Abstract
The invention provides a tail self-sealing lock bolt which comprises a screw head and a threaded column, wherein the screw head is fixedly connected with the head of the threaded column into a whole; a stepped shaft is arranged at the tail of the threaded column, and the diameter of the stepped shaft is smaller than that of the head of the threaded column; the stepped shaft is wrapped by a tail sleeve, and the diameter of the tail sleeve is equal to that of the head of the threaded column; external threads are respectively processed on the outer diameter surfaces of the threaded column and the tail sleeve in an integral way; the tail sleeve is made of a elastic non-metallic material. When the tail self-sealing lock bolt is used, the elastic action directly acts on the threaded column, thus being prevented from being loosened. Furthermore, the tail sleeve has larger elastic deformation, and a threaded hole is directly sealed, so that the bolt can bear higher screwing force.
Description
Art
The invention belongs to hardware technical field, especially relate to a kind of afterbody selfsealings chek bolt.
Background technique
Bolt is a kind of cylindrical threaded fastening piece, is also often called screw.Can be directly used in machinery, can with nut adapted.Traditional bolt is directly overall adopts Structural Hardware, in use, directly adopts screw-thread fit to lock with nut or part.But traditional bolt in use, be usually used on the parts that take regular exercise or shake, bolt easily produces after a long time use and loosens, and what easily make locking element be locked is firm not.Therefore bolt usually also can be assisted with some resilient pads in the process using connection, and prevent from loosening, assembly process is comparatively loaded down with trivial details.And traditional being threaded, also have the gap of some after being threaded between the internal thread of metal parts and outside thread, if therefore bolt is used in some structures run through, if be used for sealing gas or liquid, just than being easier to leakage of leaking gas; Therefore traditional bolt usually also needs to use special sealing gasket in the process of sealing, sometimes also needs to design special sealing configuration.
Conventional bolt is carrying out only producing tightening force by the screw thread generation deformation firmly tightening bolt bolt constantly in fastening process in addition, because these deformation mainly concentrate on several screw threads of bolt head, therefore the main tightening force of bolt provides primarily of several screw threads of stud end.Easily the outside thread of bolt is damaged when screw thread torsion is excessive like this.
Summary of the invention
For above-mentioned problem, the object of the present invention is to provide a kind of easy to use, after a procedure can auto lock, prevent from loosening, self-sealing afterbody selfsealings chek bolt can be carried out in double thread hole simultaneously.
The technical solution adopted for the present invention to solve the technical problems is: this afterbody selfsealings chek bolt comprises spiral shell head, screw column; Described spiral shell head is fixedly connected with one-body molded with screw column head, the afterbody of described screw column is designed with the multidiameter shaft that diameter is less than head diameter, described multidiameter shaft is enclosed with the tail cover that diameter is the same with screw column head diameter, the external diameter surface that described screw column and tail overlap is processed with integrated outside thread, and described tail cover uses resilient nonmetallic material to make.
As preferably, described tail cover uses plastics or rubber material to make.
As preferably, described spiral shell head adopts hexagon head or interior hexagonal structure.
As preferably, described tail cover is connected with adopting worm structure between multidiameter shaft.
As preferably, between described tail cover top and screw column stepped locations, be equipped with cushion.
Beneficial effect of the present invention is: this afterbody selfsealings chek bolt usage mode is similar to conventional bolt, does not need resilient pad and its sealing gasket when just this bolt uses; When this bolt uses, described tail cover part can produce larger deformation, produces elastic force to the screw column of metal, and like this when the part movement or the vibrations that use this bolt, described tail cover directly will produce elastic reaction by double thread post, prevents it from loosening.And tail cover can produce larger elastic strain, can seal in direct double thread hole, under the environment needing sealing, use this bolt will be more convenient like this, do not need to use sealing gasket and other sealing configuration, simultaneously because whole tail cover outside is all sealing surface, sealing effect is better.Due to this bolt fastened time, tail cover also can produce larger deformation, make the warping force of this bolt entirety not only act on several screw threads of stud head, the lashing force making bolt to bear like this is larger.
Accompanying drawing explanation
Fig. 1 is the structural representation in afterbody selfsealings chek bolt front.
Embodiment
Below in conjunction with drawings and Examples, the present invention is further described:
As shown in the embodiment shown in fig, this afterbody selfsealings chek bolt, it comprises spiral shell head 1, screw column 2; Described spiral shell head 1 is fixedly connected with one-body molded with screw column 2 head, the afterbody of described screw column 2 is designed with the multidiameter shaft 21 that diameter is less than head diameter, the tail described multidiameter shaft 21 being enclosed with diameter the same with screw column 2 head diameter overlaps 3, the external diameter surface that described screw column 2 and tail overlap 3 is processed with integrated outside thread, and described tail cover 3 uses resilient nonmetallic material to make.
This bolt is when specifically making, and the blank of described spiral shell head 1, screw column 2 one is first produced, and then the blank of tail cover 3 is wrapped in described multidiameter shaft 21, finally carries out outside thread processing.
This afterbody selfsealings chek bolt usage mode is similar to conventional bolt, does not need resilient pad and its sealing gasket when just this bolt uses; When this bolt uses, described tail overlaps 3 parts can produce larger deformation, produces elastic force to the screw column 2 of metal, and like this when the part movement or the vibrations that use this bolt, described tail cover 3 directly will produce elastic reaction by double thread post 2, prevents it from loosening.And tail cover 3 can produce larger elastic strain, can seal in direct double thread hole, under the environment needing sealing, use this bolt will be more convenient like this, do not need to use sealing gasket and other sealing configuration, simultaneously because whole tail cover outside is all sealing surface, sealing effect is better.
Due to this bolt fastened time, tail cover also can produce larger deformation, make the warping force of this bolt entirety not only act on several screw threads of stud head, the lashing force making bolt to bear like this is larger.
Described tail cover 3 uses plastics or rubber material to make.Use plastics or rubber material make described tail overlap 3 time, the mode of injection moulding can be adopted directly tail cover 3 to be injected into described multidiameter shaft 21 position, straight forming.
As shown in Figure 1, described spiral shell head 1 adopts hexagon head structure; Described spiral shell head 1 also can adopt interior hexagonal or other structure.
As shown in Figure 1, described tail cover 3 adopts worm structure to be connected with between multidiameter shaft 21.Adopt demountable structure between described tail cover 3 and multidiameter shaft 21, like this when described tail cover 3 damages, the mode changing tail cover 3 can be adopted to be repaired by whole bolt.Described tail overlaps between 3 tops and screw column 2 stepped locations and is also equipped with cushion 4.Described cushion 4 can play the top pressure effect to tail cover 3, and like this when this bolt is twisted, it is larger that described tail overlaps 3 deformation quantities, and double thread hole produces larger grasp, makes bolt whole stressed more balanced.
