Technical Field
The utility model relates to a bolt technical field specifically is a fastening type check bolt.
Background
The bolt is a mechanical part, a cylindrical threaded fastener matched with a nut, a fastener consisting of a head part and a screw (a cylinder with an external thread) needs to be matched with the nut and is used for fastening and connecting two parts with through holes, the connection form is called bolt connection, although the use of the bolt can be realized in the prior art, the problem that the bolt is easy to loosen due to the fact that the bolt is fixed only through a threaded structure in the use process, and meanwhile, the problem that the bolt is easy to loosen due to the fact that the bolt is fixed only through the threaded structure in the use process still exists.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a fastening type check bolt to only appear not hard up problem through the helicitic texture is fixed easily in the use that proposes in solving above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme: a fastening type anti-loose bolt comprises a first bolt head and a first threaded rod, wherein the lower end of the first bolt head is fixedly connected with the first threaded rod, and an auxiliary assembly is arranged inside the lower portion of the first threaded rod;
the auxiliary assembly comprises a second bolt head, a cushion block and a second threaded rod;
the second threaded rod is connected to the inner wall of the first threaded rod in a threaded mode, the upper end of the second threaded rod is fixedly connected with a second bolt head, and a cushion block is fixedly connected to the lower end of the second threaded rod.
Preferably, a notch is processed on the lower inner wall of the first threaded rod.
Preferably, a limiting component is arranged inside the cushion block;
the limiting assembly comprises a clamping block, a spring and a cross rod;
the fixture blocks are located on the left side and the right side of the cushion block, cross rods are fixedly connected to the upper side and the lower side of the inner side wall of each fixture block, springs are arranged on the outer walls of the cross rods, and the inner side and the outer side of each spring are fixedly connected with the fixture blocks and the cushion block respectively.
Preferably, a conical surface is machined in the lower end of the first threaded rod.
Compared with the prior art, the beneficial effects of the utility model are that: this fastening type check bolt:
through the matching among the first threaded rod, the second threaded head, the second threaded rod, the fixture block and the spring, the second bolt head is held tightly in the process of rotating the first threaded rod, the second threaded rod is prevented from rotating, the second threaded rod and the fixture block can be driven to move outwards while the first threaded rod is screwed into the threaded hole inwards, the fixture block and the first bolt head are clamped inwards to realize fixation, and the problem that looseness is easy to occur only through the fixation of a threaded structure in the use process is avoided;
through first threaded rod, the second threaded rod, the fixture block, the cooperation between the conical surface and the first bolt head, because the screw thread direction of first threaded rod and second threaded rod is just opposite, consequently at the in-process that first threaded rod was twisted, first bolt head and fixture block move inwards in step, twist out the in-process, first bolt head and fixture block move outwards in step, and the conical surface that receives first threaded rod at extreme position fixture block stops inwards to withdraw, can take out, avoided current check bolt need carry out other operations again after twisting the main bolt and just can realize fixed problem.

Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-4, the present invention provides a technical solution: the utility model provides a fastening type check bolt, including first bolt head 1 and first threaded rod 5, the lower extreme rigid coupling of first bolt head 1 has first threaded rod 5, the inside auxiliary assembly 3 that is provided with in below of first threaded rod 5, auxiliary assembly 3 includes second bolt head 301, cushion 302 and second threaded rod 303, second threaded rod 303 threaded connection is at the inner wall of first threaded rod 5, first threaded rod 5 rotates and to order about second threaded rod 303 and remove, the upper end and the fixed linking to each other of second bolt head 301 of second threaded rod 303, the lower extreme rigid coupling of second threaded rod 303 has cushion 302, the processing of the below inner wall of first threaded rod 5 has breach 4, breach 4 can supply cushion 302 to remove.
Spacing subassembly 2 is provided with in the inside of cushion 302, spacing subassembly 2 includes fixture block 201, spring 202 and horizontal pole 203, a plurality of fixture blocks 201 are located the left and right sides of cushion 302, the equal rigid coupling in both sides has horizontal pole 203 about the inboard inner wall of fixture block 201, the outer wall of horizontal pole 203 is provided with spring 202, spring 202's elastic coefficient can be decided according to concrete in service behavior, spring 202's inside and outside both sides respectively with fixture block 201 and cushion 302 fixed continuous, the inside processing of the lower extreme of first threaded rod 5 has conical surface 6.
When the fastening type anti-loosening bolt is needed to be used, firstly, a user can insert the first threaded rod 5 provided with the second threaded rod 303 into the corresponding threaded hole and starts to rotate at the meshing position, in the inserting process, the clamping blocks 201 on two sides can be blocked by the inner wall of the threaded hole, the clamping block 201 moves inwards and retracts into the first threaded rod 5, before the clamping block 201 starts to rotate, the clamping block 201 is separated from the range of the threaded hole, the elastic force of the spring 202 pushes the clamping block 201 to pop out outwards, then the second bolt head 301 is held tightly in the process of rotating the first threaded rod 5, the second threaded rod 303 is prevented from rotating, the second threaded rod 303 and the clamping block 201 can be driven to move outwards while the first threaded rod 5 is screwed into the threaded hole inwards, the fastening is realized by inwards clamping the clamping block 201 and two sides of the first bolt head 1, and the problem that the fastening is easy to loosen only through a threaded structure in the using process is avoided, meanwhile, the thread directions of the first threaded rod 5 and the second threaded rod 303 are just opposite, so that the first bolt head 1 and the fixture block 201 synchronously move inwards in the screwing process of the first threaded rod 5, the first bolt head 1 and the fixture block 201 synchronously move outwards in the screwing process, the fixture block 201 is blocked by the conical surface 6 of the first threaded rod 5 at the limit position and retracts inwards, the locking bolt can be taken out, and the problem that the existing locking bolt can be fixed only by performing other operations after being screwed into a main bolt is solved.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
