Description

Novel split formula bolt structure

Technical Field

The utility model relates to a bolt technical field especially relates to a novel split formula bolt structure.

Background

Bolt: mechanical parts, cylindrical threaded fasteners fitted with nuts. A fastener consisting of a head part and a screw (a cylinder with external threads) needs to be matched with a nut and is used for fastening and connecting two parts with through holes. This form of connection is known as a bolted connection. If the nut is unscrewed from the bolt, the two parts can be separated, so that the bolt connection belongs to detachable connection.

In daily life, the bolt is slippery, and when the bolt is slippery, the bolt is always troublesome because the workpiece cannot be screwed down, and the bolt cannot be detached and replaced by a new bolt.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the defects existing in the prior art and providing a novel split type bolt structure.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a novel split formula bolt structure, includes two side bolts, two limit bolts and a central bolt, central bolt establishes on the relative one side inner wall of two side bolts and two limit bolts, the side bolt all includes spiral shell head and screw rod portion, and the spiral shell head is close to one side of central bolt and opens there is the draw-in groove, screw rod portion includes side screw rod and bail, and the bail symmetry is provided with on the side screw rod is close to one side inner wall of central bolt, the limit bolt includes bayonet lock and limit screw rod, and goes up the bayonet lock and fix on one side outer wall that the central bolt was kept away from on the top of limit screw rod, the nail catching groove has been seted up to one side that the limit bolt is close to central bolt, central bolt is T type structure, and the both sides outer wall of central bolt all is equipped with the support.

Preferably, the nail catching grooves on the side bolts are pin grooves which are arranged on two sides in parallel, and the nail catching grooves and the side faces of the staple bolts on the side bolts form clamping matching.

Preferably, the both sides of the spiral shell head portion of side bolt all are equipped with the side buckle, and the both sides outer wall of side buckle and last bayonet lock forms the joint cooperation.

Preferably, last draw-in groove on the side bolt is the right angle structure, and the support is buckled and is L type structure, the bottom outer wall joint that the support was buckled is on the inner wall of last draw-in groove.

Preferably, the middle part of the central bolt is a central column, and the outer walls of four sides of the central column are respectively in sliding clamping fit with the two side bolts and the four inner sides of the two side bolts.

The utility model has the advantages that: the bolt structure divides the traditional bolt into five parts according to the principle of the open-hole lock, the five parts are assembled together to form a complete bolt, if a central object block is drawn out, the bolt can be divided into five parts, and in the process of dividing the bolt, the bolt can be only divided from the inside, so that the space outside the bolt can not be influenced; the bolts can be removed even if they have been installed in the instrument or device, needless to say that the already installed instrument or device is removed again. This can save people's energy and material resources. After the bolt is detached, the damaged part can be replaced by a new part, and other parts can be reused, so that the bolt is environment-friendly and convenient.
