Abstract

The utility model discloses a hexagon head bolt provided with a self-locking function, comprising a hexagon head bolt (1), a nylon locking element (2) for preventing loosening of the bolt in use is inlaid in the thread portion of the hexagon head bolt (1); the head portion of the hexagon head bolt (1) is provided with one to three fuse through holes (3). The hexagon head bolt in the utility model via disposing fuse through holes at the head portion of the hexagon head bolt, and inlaying the nylon locking element at the thread portion of the hexagon head bolt, when the hexagon head bolt is screwed up and in serial connection with adjacent bolts, metal fuses are disposed at the head portion, and under the spring action of the nylon locking element of the thread rod portion, the hexagon head bolt can play effective self-locking effect. The hexagon head bolt in the utility model can be directly screwed to a base body for use, and can be used matching with a nut. The hexagon head bolt is advantaged by high efficient anti-loosening function, simple structure, easy making, and lower manufacture cost.

Description

A kind of hexagon head bolt with auto-lock function
Technical field
The utility model relates to a kind of hexagon head bolt with auto-lock function, belongs to technical field of fastening.
Background technique
At present, hexagon head bolt has been widely used in all trades and professions, but that most of bolt of the prior art all exists when using its anti-loosening property is relatively poor, when particularly using in the workplace of some vibrations, is easy to take place the phenomenon of bolt looseness.For addressing this problem, many self-locking screws with locking functions have also appearred in the prior art, though the each have their own advantage become flexible of preventing of these self-locking screws, these self-locking screw ubiquities complex structure, fabricating cost problem of higher.Therefore, existing hexagon head bolt still can not satisfy the needs of use.
Summary of the invention
The purpose of this utility model is, provides a kind of have efficient locking functions and the hexagon head bolt with auto-lock function simple in structure, that making is easy, fabricating cost is lower, to overcome the deficiencies in the prior art.
The technical solution of the utility model: a kind of hexagon head bolt of the present utility model with auto-lock function, comprise existing hexagon head bolt structure, on the helical thread portion of hexagon head bolt, be inlaid with nylon locking element loosening when being used to prevent the bolt use.
Above-mentioned 1~5 pitch of threaded stem front end that is embedded in the front end of the nylon locking element on the hexagon head bolt helical thread portion apart from hexagon head bolt.
The above-mentioned plunger type that is shaped as, stripe shape, the patch type or ring-like that is embedded in the nylon locking element on the hexagon head bolt helical thread portion.
Head at above-mentioned hexagon head bolt also is provided with 1~3 safety fuse cutout through hole.
Owing to adopted technique scheme, the utility model is provided with the safety fuse cutout through hole by the head at hexagon head bolt, simultaneously inlay the nylon locking element at the helical thread portion of hexagon head bolt, like this after hexagon head bolt is tightened by putting on the metal safety fuse cutout at head and with the series connection of adjacent bolt, and under the elastic force effect of the nylon locking element of thread rod part, hexagon head bolt of the present utility model can produce effective self-locking action.The utility model can directly be screwed into matrix and use, also can with the nut use that matches.Therefore, the utility model compared with prior art, the utility model not only have efficient locking function but also have simple in structure, make easily, advantage that fabricating cost is lower.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Structural representation when Fig. 2 is the plunger type for nylon locking element of the present utility model;
Structural representation when Fig. 3 is stripe shape for nylon locking element of the present utility model;
Structural representation when Fig. 4 is ring-like for nylon locking element of the present utility model;
Structural representation when Fig. 5 is the patch type for nylon locking element of the present utility model.
Description of symbols in the accompanying drawing: 1-hexagon head bolt, 2-nylon locking element, 3-safety fuse cutout through hole.
Embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Embodiment of the present utility model: structure of the present utility model as shown in Figure 1, when making a kind of hexagon head bolt with auto-lock function of the present utility model, the structure of its hexagon head bolt 1 can directly adopt existing hex head bolt structure according to the needs that use, directly inlay nylon locking element 2 loosening when being used on fixing prevent the bolt use during making on the helical thread portion of hexagon head bolt 1, the Manufacturing material of nylon locking element 2 can adopt nylon material of the prior art; Carrying out nylon locking element 2 when inlaying, the scope of the front-end control of the nylon locking element 2 on hexagon head bolt 1 helical thread portion in 1~5 pitch of threaded stem front end of distance hexagon head bolt 1 will be embedded in; The shape that is embedded in the nylon locking element 2 on hexagon head bolt 1 helical thread portion is made into plunger type (as shown in Figure 2), or is made into stripe shape (as shown in Figure 3), or be made into ring-like (as shown in Figure 4), or be made into patch type (as shown in Figure 5); Bore 1~3 safety fuse cutout through hole 3 at the head of hexagon head bolt 1 then.
