Further, bottom plate 213 is provided with limiting stand 2132 at the forward edge of groove 2131, when the groove of connecting rod 2211
When being positioned over to portion in groove 2131, limiting stand 2132 limits connecting rod 2211 and moved.
As shown in figure 5, stop pin assembly 23 includes stop pin 231 and locking elastic part 232, unblock pin assemblies 24 include solution
Lock pin 241 and latch elastic component 242, stop pin 231 and locking elastic part 232 are front and rear respectively to be positioned over the first cylinder groove 2111
Interior, stop pin 231 is in transverse shifting in the first cylinder groove 2111；Elastic component 242 is front and rear respectively is positioned over for latch 241 and unblock
In second cylinder groove 2112, latch 241 is in transverse shifting in the second cylinder groove 2112.
Further, the front end of the first cylinder groove 2111 and the second cylinder groove 2112 offers default insertion sky along preset strokes
Between 2115, the preset strokes can be understood as the shift length that stop pin 231 and latch 241 move, and stop pin 231 slides
Just it can realize that lock-out state, and latch 241 can realize released state just after sliding the shift length after the shift length,
Stop pin 231 is offered to lower convex platform 233 to the extension of the lower section of default run-though space 2115, and latch 241 is to default run-though space
2115 top extensions offer upward boss 243, and upward boss 243 is located in front of lower convex platform 233, and upward boss 243
Top is located at the top to the bottom of lower convex platform 233.
Further, rear baffle 215 is respectively equipped with boss in the contact position of locking elastic part 232 and unblock elastic component 242
2151, the precompression of locking elastic part 232 and unblock elastic component 242 can be configured by the height of the boss 2151.
Crank 4 is provided with by traction body 3, reset wind spring, the sliding traction dress of this example are installed at the rotary shaft of the crank 4
Traction is put by the specific works state diagram of traction body 3 as shown in fig. 6, concrete operating principle is：
Shown in original state such as Fig. 6 (a), link component 22 is positioned over bottom plate 213 by the transverse part of connecting rod 2211
Groove 2131 in, in original state, stop pin 231 is supported to inside the notch of the first cylinder groove 2111 by baffle plate 2215, unblock
The front end of pin 241 protrudes from the outside of front apron 214, and latch 241 is limited in front apron 214. by upward boss 243
Sliding block SBR is drawn, such as Fig. 6 (b), is back to by traction cable 11 by sliding block 12 is drawn by after traction body 3
Side, when crank 4 contacts with bottom plate 213, crank 4 can take advantage of a situation swing along the bottom bevel of bottom plate 213, smooth to draw slip 12
By the way that crank 4 is resetted by rear resilience completely in traction sliding block 12.
Clamping prepares to arrive clamp position, and as shown in Fig. 6 (c), Fig. 6 (d), Fig. 6 (e), traction sliding block 12 is in traction cable 11
In the case of front haulage, traction sliding block 12 moves forward, and crank 4 is snapped into a few font jacking blocks 2213, and crank 4 withstands several words
Type jacking block 2213, make link component 22 is overall to move up, crank 4 is also with rotating, when crank 4 turns to extreme position
When, now, link component 22 is jacked up completely, and baffle plate 2215 departs from the notch of the first cylinder groove 2111, and stop pin 231 is being locked
Elastic force effect lower outwards ejection, the stop pin 231 for determining elastic component 232 slip into what a few font jacking blocks 2213 and cross beam frame 2212 opened up
In open slot 2214, realize that stop pin 231 locks link component 22, for stop pin 231 outwards during ejection, it is convex downwards
When platform 233 contacts with upward boss 243, limitation stop pin 231 continues outwards to eject；Now, the termination of crank 4 is stuck in connection
Between the positive stop lug boss 22111 and pedestal 211 of bar 2211, e.g., crank 4 can be T-type structure, and the horizontal termination of crank 4 is by card
Between positive stop lug boss 22111 and pedestal 211, so as to realize clamping of the link component 22 to crank 4, after the completion of clamping, quilt
Traction body 3 can move forward and backward under the drive of traction sliding block 12.
It is controllable when can not be moved on when being moved into place by traction body 3 shown in release conditions such as Fig. 6 (f) and Fig. 6 (g)
System traction sliding block 12 continues firmly before to push away by traction body 3, when the contact force of latch 241 and crank 4 is greatly to more than releasing force,
The releasing force refers to locking elastic part 232 and unlocks the pressure summation of elastic component 243 in the locked state, and latch 241 is bent
Handle 4 is pushed back in the second cylinder groove 2112, meanwhile, angle lock pin 241 drives stop pin 231 to bounce back, so as to which the pin 231 that unlocks is to even
The screens of frame component 22 is connect, the elastic component 222 that is reset of link component 22 is promoted and is moved down, it is final to discharge crank 4, the quilt of crank 4
After release, traction sliding block 12 returns, and crank 4 smoothly can be deviate from from link component 22, so as to realize traction sliding block 12 and quilt
The separation of traction body 3.
The sliding traction device of this example can chronologically realize traction sliding block 12 and the mechanical clamping and release by traction body 3
Separation, without the electric device such as sensing and driving, light small simple, the general beneficial effect such as reliable is achieved, can be applied to effectively
The space structures such as load extending arm, film solar sail, thin film solar battery array, film antenna expansion field, production line material are defeated
The field such as send.
Use above specific case is illustrated to the present invention, is only intended to help and is understood the present invention, not limiting
The system present invention.For those skilled in the art, according to the thought of the present invention, can also make some simple
Deduce, deform or replace.
