Description
Technical field
The utility model relates to a kind of fasteners, and more specifically it is related to a kind of check bolt.
Background technique
The bolt in standard component is mostly that screw head and stud are directly linked together at present, does not have anti-loosening function, makes
With easily being loosened in the process because shaking, the maintenance rate using the screw device is increased, is brought inconvenience to user.
In the prior art, the Chinese patent document that application publication number is CN104564991A discloses a kind of novel anti-
Loose bolt, is equipped with ring flange in the side of hexagonal screw head, is equipped with stud, the hexagonal screw head, ring flange in the side of ring flange
With being in the same center line at center for stud, the diameter of the ring flange is greater than the diameter of hexagonal screw head.In the flange
It is laid with one week locking movable tooth on the one side periphery of disk, has the effect of preventing from loosening.
But the check bolt of this set is equipped with for only leaning on locking movable tooth and carries out preventing from loosening, anti-loosening effect
Difference could be improved.
Utility model content
In view of the deficienciess of the prior art, having prevents the purpose of this utility model is to provide a kind of check bolt
The effect of loosening.
To achieve the above object, the utility model provides following technical solution: a kind of check bolt, include spiral shell body with
And the nut integrally generated with the spiral shell body, the spiral shell is equipped with partes glabra with it, anti-loosing slice is slidably equipped on the partes glabra, described
Protruded towards nut dish-shaped in the middle position of anti-loosing slice.
By using above-mentioned technical proposal, it is slidably equipped with anti-loosing slice on partes glabra, it is locking when being reinforced using the bolt
Piece is moved to abutted with nut after deformation occurs, when after bolt is fixed not by artificial active force, anti-loosing slice has one to nut
A active force, and nut and spiral shell body are integrally fixedly installed so that external screw thread with spiral shell and cooperate the outer bolt internal screw thread it
Between have an opposing force, play prevent loosen effect.
The utility model is further arranged to: the anti-loosing slice is equipped with interior spiral shell corresponding with the external screw thread with spiral shell
Line.
By using above-mentioned technical proposal, anti-loosing slice can be limited in partes glabra by being threadedly coupled with spiral shell body by anti-loosing slice
On, have the function of that anti-loosing slice is prevented to be detached from spiral shell body.
The utility model is further arranged to: the introduction part far from nut is equipped with the spiral shell.
By using above-mentioned technical proposal, the design of introduction part be threaded into spiral shell convenient for anti-loosing slice and with it is outer with spiral shell
It is threadedly engaged.
The utility model is further arranged to: the anti-loosing slice towards on one end of nut integrally formed with a plurality of anti-skidding recessed
Slot.
By using above-mentioned technical proposal, the setting of antiskid groove increases the surface roughness of anti-loosing slice, and increase rubs
Power is wiped, there is antiskid effect, so that nut is more stable when fixed with anti-loosing slice, further promotes anti-loosing effect.
The utility model is further arranged to: the length direction of the antiskid groove is directed toward the axial line of nut.
By using above-mentioned technical proposal, for nut in rotation, nut and antiskid groove are close in 90 degree of directions movements, tool
There is preferable antiskid effect.
The utility model is further arranged to: the nut is equipped with multiple raised lines towards one end of anti-loosing slice.
By using above-mentioned technical proposal, the surface roughness of nut is strengthened, increasing friction force improves anti-skidding effect
Fruit.
The utility model is further arranged to: zinc-aluminium painting is equipped on the spiral shell body, the nut and the anti-loosing slice
Layer.
By using above-mentioned technical proposal, there is etch-proof effect.
The utility model is further arranged to: the nut is equipped with plum blossom groove, the edge and spiral shell of the plum blossom groove
Crown is provided with lead angle between end.
By using above-mentioned technical proposal, plum blossom groove can cooperate the tool of wabbler to be rotated, and the setting of lead angle rises
To the effect of guidance, it is inserted into plum blossom groove convenient for tool.
In conclusion the bolt in the utility model can make anti-loosing slice when fixed, deformation occurs, after the completion of fixation,
The deformation power of anti-loosing slice make bolt and its with stronger between unification fixing piece, prevent from loosening, while antiskid groove and convex
The setting of item plays stability of the nut with anti-loosing slice after fixed, further strengthens locking effect.

Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
Present embodiment discloses a kind of check bolts, as shown in Figure 1, including spiral shell body 1 and integrally generating with spiral shell body 1
Nut 2,2 upper end of nut is provided with plum blossom groove 3, and is provided with lead angle 4 between 2 top of plum blossom groove 3 and nut, is inserted into convenient for tool
To plum blossom groove 3.
It as shown in Figure 1 and Figure 2, successively include partes glabra 5, threaded portion 6 from close nut 2 to separate nut 2 on spiral shell body 1
With introduction part 7, which is external screw thread, is slidably equipped with anti-loosing slice 8 on partes glabra 5, perforation 9 is provided on the anti-loosing slice 8, locking
For piece 8 towards the internal screw thread being provided on one end of spiral shell body 1 with external screw thread cooperation, the mode being connected through a screw thread makes 8 turns of anti-loosing slice
Enter to partes glabra 5, has the effect of preventing anti-loosing slice 8 from skidding off spiral shell body 1.And the setting of introduction part 7 have facilitate anti-loosing slice 8
Go to the effect of threaded area.It is provided with Aluminum Coating on spiral shell body 1, nut 2 and anti-loosing slice 8, there is etch-proof effect
As shown in Fig. 2, the middle section of the anti-loosing slice 8 protruded towards nut 2 it is dish-shaped, the anti-loosing slice 8 have deformation energy
Power, when bolt is tightened fixed, anti-loosing slice 8 is first abutted with nut 2, and then as tightening for bolt, deformation occurs, works as spiral shell
When bolt fixation no longer rotates, there is one between the physics that nut 2 fixes bolt and the bolt by the deformation power of anti-loosing slice 8
Separate active force, to achieve the effect that prevent from loosening.
As shown in Figure 1 and Figure 2, anti-loosing slice 8 is towards being provided with circumferential equally distributed multiple antiskid grooves on one end of nut 2
10, the setting of antiskid groove 10 increases the surface roughness of anti-loosing slice 8, and increasing friction force has antiskid effect, to make
It is more stable when obtaining nut 2 with the fixation of anti-loosing slice 8, further promote anti-loosing effect.And the length of the antiskid groove 10 is rectangular
It is directed toward the axle center of nut 2, in rotation, nut 2 and antiskid groove 10 have preferable such nut 2 close in 90 degree of rotations
Antiskid effect.Nut 2 has a plurality of raised line 12 towards integrally generating on one end of anti-loosing slice 8, reinforces antiskid effect, thus further
Reinforce anti-loosing effect.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all practical at this
Within novel design concept, any modification, equivalent replacement, improvement and so on should be included in the protection of the utility model
Within the scope of.
