This fixing rail 100 is provided with a support fixing part 600 and a detachable fixing clip 110, so that the user can selectively couple the fixing rail 100 to the position (height) requested by the user. . For example, the fixing clip 110 may be inserted and coupled to the support fixing part 600 in a fitting form.

A first guide groove 120 is formed in this fixed rail 100 to guide the movement of the ball 210 provided in the retainer 200, and the ball 210 moves in the longitudinal direction of the first guide groove 120. can be moved accordingly. This first guide groove 120 is in rolling contact with a portion of the outer peripheral surface of the ball 210 being seated.

And the moving rail 300 is configured to slide from the fixed rail 100. In this moving rail 300, a second guide groove 310 is formed in rolling contact with the ball 210 provided in the retainer 200, and the ball 210 moves along the longitudinal direction of the second guide groove 310. can be moved

In this way, as the retainer 200 with a plurality of balls 210 is disposed between the fixed rail 100 and the moving rail 300, the moving rail 300 moves smoothly (into or out of the fixed rail 100). withdrawal) can be made.

Meanwhile, the locking bracket 400 is coupled to one end of the fixed rail 100.

This locking bracket 400 is configured to restrain the movement of the moving rail 300 when the moving rail 300 is completely retracted. That is, the locking bracket 400 is inserted into the locking fixing groove 531 provided in the cap 500 and limits the withdrawal of the moving rail 300.

Such a locking bracket 400 may include a bracket body portion 410, a first protrusion 420, a second protrusion 430, a locking fixing portion 440, and a buffer portion 450.

Here, the bracket body portion 410 forms the external shape of the locking bracket 400.

This locking bracket 400 is formed with a coupling hole 402 into which the coupling protrusion 130 provided on the fixing rail 100 is inserted, so that the locking bracket 400 can be coupled to the fixing rail 100.

And the first protrusions 420 protrude from the top and bottom of the bracket body 410 to face each other. This first protrusion 420 protrudes from the bracket body 410 and protrudes outward from the bracket body 410 toward the support fixture 600 fixed to the inner wall.

The pair of first protrusions 420 are provided with locking fixing parts 440, and the spaced apart locking fixing parts 440 form an fitting space 401 into which the locking guide part 530 is inserted. In the process of inserting the moving rail 300 into this fitting space 401, the locking guide portion 530 provided on the cap 500 may be inserted.

When the movable rail 300 is fully retracted, the locking fixing part 440 is inserted into the locking fixing groove 531 formed in the locking guide part 530, thereby restricting the movement of the movable rail 300. The process of introducing the moving rail 300 will be described in detail later.

In this way, the locking fixing part 440 inserted into the locking fixing groove 531 is formed to be gently curved and convex to enable elastic deformation. This locking fixture 440 may be made of, for example, a leaf spring.

And the second protrusion 430 protrudes from one end of the bracket body portion 410. Here, the second protrusion 430 is formed to protrude inward from the bracket body portion 410 in the opposite direction to the first protrusion 420.

This second protrusion 430 is provided with a buffer portion 450, and the buffer portion 450 causes one end of the fixed rail 100 to directly hit the cap 500 during the retraction of the moving rail 300. This is done to prevent noise.

Like the locking fixing portion 440, the buffer portion 450 is formed to be gently curved and convex. At this time, the convex surface of the buffer portion 450 is disposed to face the inner surface of the cap 500. Like the locking fixing unit 440, this buffer unit 450 may be made of a leaf spring capable of elastic deformation.

Therefore, for example, in the process of fully retracting the moving rail 300, if excessive force is applied to the moving rail 300 at once and the cap 500 hits one end of the fixed rail 100, the buffer portion 450 ) prevents the generation of impact noise caused by collision between parts by elastically supporting the cover portion 510 provided on the cap 500.

Here, the first fixing part 521 is coupled to the cover part 510 and is disposed on the outer surface of the moving rail 300 in a state in which the cap 500 and the moving rail 300 are coupled.

And the second fixing part 522 is disposed on the inner surface of the moving rail 300 in a state in which the cap 500 and the moving rail 300 are coupled. A fastening fixing groove 524 is formed at the other end of the second fixing part 522. This fastening fixing groove 524 is inserted and fixed into the fastening fixing part 301 formed on the moving rail 300 when the cap 500 and the moving rail 300 are coupled.

And the connection part 523 is formed to connect the first fixing part 521 and the second fixing part 522.

One end of this connection part 523 is connected to the first fixing part 521, and the other end is connected to the second fixing part 522. When such a cap 500 is coupled to the moving rail 300, the connection part 523 is inserted through the fastening hole 302 and the end of the second fixing part 522 is connected to the fastening fixing part 301. It is inserted and fixed, and the first fixing part 521 is supported on the outer surface of the moving rail 300.

And the locking guide part 530 protrudes from the cover part 510 like the cap fixing part 520.

Locking fixing grooves 531 are formed on the upper and lower surfaces of the locking guide portion 530. The locking fixing part 440, which is elastically restored in the process of completely retracting the moving rail 300, is inserted into this locking fixing groove 531.

This locking guide portion 530 is inserted into the fitting space portion 401 when the moving rail 300 is completely retracted. In this process, the locking fixture 440 elastically supports the locking fixture groove 531 to restrict the withdrawal of the moving rail 300.

In this way, with the locking fixing part 440 inserted into the locking fixing groove 531, in order to withdraw the movable rail 300, the movable rail 300 must be pulled with a force exceeding a certain level, but the movable rail 300 is fixed. It can be withdrawn from the rail 100.

In this way, the sliding device 1000 is provided with a locking bracket 400 and a cap 500 that restrain the movement of the moving rail 300 when the moving rail 300 is fully retracted, so that, for example, an oven ( The sliding device 1000 can be prevented from being pulled out on its own during the process of opening the door 2 of 10).

The cap 500 provided in this sliding device 1000 has a simple coupling structure with the moving rail 300, so when the cap 500 is damaged, the operator can easily replace the cap 500.

In addition, the locking bracket 400 and the fixing rail 100 have a simple coupling structure, so when the locking bracket 400 is damaged, the worker can easily replace the locking bracket 400.

In this way, the cap 500 and the locking bracket 400 provided in the sliding device 1000 provide effective locking control and are also easy to replace.

Here, the conventional sliding device controls the locking of the sliding device through structural changes in the moving rail or fixed rail. In this conventional sliding device, if a problem occurs in the locking operation, the moving rail or the fixed rail itself must be replaced, which not only complicates the replacement process but also increases the replacement cost.

However, if a problem occurs in the sliding device 1000 according to the present invention in the locking state, the replacement work is simple because only the damaged cap 500 or the locking bracket 400 needs to be replaced.

As shown in FIG. 6, in the process of completely retracting the moving rail 300, the front end of the locking guide portion 530 is inserted into the fitting space portion 401.

Here, the width D1 of the front end of the locking guide part 530 is wider than the spaced width D2 between the locking fixing parts 440 facing each other in the restored state, so that the front end of the locking guide part 530 fits into the space. In the process of being inserted into the unit 401, the locking fixture 440 is pressed and elastically deformed.

And when the moving rail 300 is completely inserted, the locking fixing part 440 is located in the locking fixing groove 531 formed in the locking guide part 530, and the locking fixing part 440 in a pressurized state restores elasticity. This elastically supports the locking fixing groove 531.

In this way, in order to withdraw the movable rail 300 while the locking fixing part 440 is inserted into the locking fixing groove 531, a force of more than a predetermined amount must be applied to the movable rail 300, but the movable rail 300 It can be withdrawn from the fixed rail 100.

However, this is only a preferred embodiment of the present invention, and the scope of the present invention is not limited by the scope of description of this embodiment.
