Abstract

The utility model discloses a special combined nut. The special combined nut comprises a nut core and a hexagonal socket. The nut core is shaped like a cylinder, a threaded hole is formed in the center of the cylinder, and three convex ribs are symmetrically arranged on the outer circle of the cylinder. The hexagonal socket comprises a hexagonal block and a cylindrical socket, the hexagonal block is arranged on the upper portion of the cylindrical socket, a core hole is formed in the cylindrical socket, three triangular grooves are symmetrically formed in the hole wall of the core hole, and the nut core is arranged in the core hole. Through the method, the special combined nut is provided, the nut core can be screwed only when in cooperation with the hexagonal socket, the hexagonal socket is taken down after the nut core is tightened, and thus the anti-theft performance is good; the end of the hexagonal socket can be suitable for an ordinary wrench, cost for arranging a special wrench is saved, and the special combined nut is low in cost and wide in application range.

Description

A kind of special combination nut

Technical field

The utility model relates to specialized nut design field, particularly relates to a kind of special combination nut.

Background technique

Nut is exactly nut, is the part that is used for playing the role of fastening together with a kind of and bolt or screw rod are screwed in, nut be almost manufacturing machine must use a kind of element, also more in the application of building or other field, relate to the various tool of live and work.The kind of nut is a lot, except common nut, also has self-locking nut, lock nut, locking nut, four paws nut, screw-in nut, lock nut, thin bar screw attaching nut etc. to have the nut of specific function.

Equipment component or vehicle, for antitheft or false proof needs have used special nut, due to the narrow limitation of common wrench, just special nut must adopt special spanner to turn, therefore most of special nut also can be called anti-theft nut.The appearance of anti-theft nut has greatly reduced the stolen phenomenon of object has occurred because turning nut, but anti-theft nut must be equipped with special spanner, has improved production cost, has affected further popularization.

Model utility content

The technical problem that the utility model mainly solves is to provide a kind of special combination nut, reduces the expense of special spanner, and with low cost, theftproof performance is good.

For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of special combination nut is provided, comprise: nut core body and Hexagonal jacket, described nut core body profile is a cylindrical body, described cylindrical central position is provided with a tapped hole, on described cylindrical cylindrical, be symmetrically arranged with three convex tendons, described Hexagonal jacket comprises Hexagon square and cylindrical sleeves, described Hexagon square is arranged on the top of cylindrical sleeves, described cylindrical sleeves inside is provided with a core body hole, on the hole wall in described core body hole, be symmetrically arranged with three triangular grooves, described nut core body is arranged in core body hole.

In preferred embodiment of the utility model, the cross section of described three convex tendons is respectively a triangle, and the length of described three convex tendons is identical with cylindrical height.

In preferred embodiment of the utility model, the middle part of described Hexagon square is provided with a through hole.

In preferred embodiment of the utility model, the diameter in described core body hole is identical with cylindrical outside diameter.

In preferred embodiment of the utility model, described triangular groove and convex tendon match.

The beneficial effects of the utility model are: a kind of special combination nut that the utility model is pointed out, nut core body must just can turn under the cooperation of Hexagonal jacket, tightening rear Hexagonal jacket takes off, theftproof performance is good, and Hexagonal jacket end can be suitable for common wrench, reduce the expense that is equipped with special spanner, with low cost, applied widely.

Brief description of the drawings

In order to be illustrated more clearly in the technological scheme in the utility model embodiment, below the accompanying drawing of required use during embodiment is described is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing, wherein:

Fig. 1 is the structural representation of a kind of special combination nut one preferred embodiment of the utility model;

Fig. 2 is the structural representation of parts 2 in Fig. 1;

Fig. 3 is that the A-A of Fig. 2 is to sectional view;

In accompanying drawing, the mark of each parts is as follows: 1, nut core body, 2, Hexagonal jacket, 11, convex tendon, 21, Hexagon square, 22, cylindrical sleeves, 23, triangular groove.

Embodiment

To the technological scheme in the utility model embodiment be clearly and completely described below, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making all other embodiments that obtain under creative work prerequisite, all belong to the scope of the utility model protection.

Refer to Fig. 1 to Fig. 3, the utility model is embodiment comprise:

A kind of special combination nut, comprise: nut core body 1 and Hexagonal jacket 2, described nut core body 1 profile is a cylindrical body, described cylindrical central position is provided with a tapped hole, on described cylindrical cylindrical, be symmetrically arranged with three convex tendons 11, described Hexagonal jacket 2 comprises Hexagon square 21 and cylindrical sleeves 22, described Hexagon square 21 is arranged on the top of cylindrical sleeves 22, described cylindrical sleeves 22 inside are provided with a core body hole, on the hole wall in described core body hole, be symmetrically arranged with three triangular grooves 23, described nut core body 1 is arranged in core body hole, Hexagon square 21 can coordinate common wrench to twist, while tightening, nut core body 1 is fixed outer bolt.

A kind of special combination nut of the utility model has adopted nut core body 1 especially, and cylindrical appearance makes common wrench be difficult to fix, and the cross section of described three convex tendons 11 is respectively a triangle, and the length of described three convex tendons 11 is identical with cylindrical height.

Further, the middle part of described Hexagon square 21 is provided with a through hole, facilitates outer bolt end to pass.

Further, the diameter in described core body hole is identical with cylindrical outside diameter, facilitates nut core body 1 to be arranged in core body hole, coordinates closely.

Further, described triangular groove 23 matches with convex tendon 11, and when Hexagonal jacket 2 is twisted, nut core body 1 rotates.

In sum, a kind of special combination nut that the utility model is pointed out, nut core body 1 only just can rotate under the twisting of Hexagonal jacket 2, and theftproof performance is good, and Hexagonal jacket 2 can be suitable for common wrench, has save the cost of special spanner, good economy performance.
