Abstract
The present invention relates to a kind of automobile-used anti-back Water-proof screw, including integrally formed nut, screw rod and guide head；Its technical characterstic is：Annular waterproof boss is made under the nut bottom surface is coaxial；The screw rod is provided with screw thread and is evenly equipped with several longitudinal anti-back slots around screw rod circumferential surface.The screw rod of the present invention is provided with screw thread and is evenly equipped with several longitudinal anti-back slots around screw rod circumferential surface；The anti-back slot is skewed slot, and its width is 0.2 0.3mm.The anti-back skewed slot has the function that out of screw to deviate from after preventing screw loosening, and circular screw rod circumferential surface is deployed troops on garrison duty and longitudinally moves back skewed slot, longitudinal anti-back chute length length, sets the anti-back effect of several straight troughs more preferable relative to the connecting portion only in nut and screw rod.
Description
Technical field
The invention belongs to technical field of fastening, particularly a kind of automobile-used anti-back Water-proof screw.
Background technology
At present, in fastening parts of automobiles product, screw is essential automobile component.But
Because it has been widely recognized and applies, for most of technical staff, lack to its technology
Improved power, cause waterproof, anticreep and the anti-theft of automobile-used screw, easy being screwed into property aspect
Some defects also be present, be related in automobile etc. on the means of transportation of personal safety as well as the property safety used
Screw be badly in need of its waterproof, anticreep and theftproof performance are further lifted, ensure driving
Member and the ride safety of automobile of passenger.
The content of the invention
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of reasonable in design, knot
Structure is simple and has the automobile-used anti-back Water-proof screw of waterproof, antitheft, anti-back and antirust function.
The present invention solves its technical problem and takes following technical scheme to realize：
A kind of automobile-used anti-back Water-proof screw, including integrally formed nut, screw rod and guide head；
Annular waterproof boss is made under the nut bottom surface is coaxial；The screw rod is provided with screw thread and ring
Several longitudinal anti-back slots are evenly equipped with around screw rod circumferential surface.
Moreover, the anti-back slot is skewed slot, its width is 0.2-0.3mm.
Moreover, uniformly it is provided with four circular theft-proof grooves on end face at the top of the nut.
Moreover, rotation indicator has integrally been made in the end wall side of the nut.
Moreover, the nut, screw rod and guiding head surface are coated with antirust coat.
The advantages and positive effects of the present invention are：
1st, making annular waterproof boss under nut bottom surface of the invention is coaxial has waterproof action.
2nd, the screw rod of the invention is provided with screw thread and is evenly equipped with number around screw rod circumferential surface
Bar longitudinal direction anti-back slot；The anti-back slot is skewed slot, and its width is 0.2-0.3mm.The anti-back is oblique
Groove has the function that out of screw to deviate from after preventing screw loosening, uniform around screw rod circumferential surface
Skewed slot is moved back in anti-longitudinal direction, longitudinal anti-back chute length length, relative to only in the company of nut and screw rod
Socket part sets the anti-back effect of several straight troughs more preferable.
3rd, four circular theft-proof grooves are uniformly provided with end face at the top of nut of the present invention, needed
It could be backed out using special tooling, there is anti-theft；And due to equal on the end face of nut top
Cloth is provided with four circular grooves, automobile inspection personnel because maintenance need knockout screw when, using special
Maintainer is facilitated quickly to unload cartridge screw with frock, it is time saving and energy saving.
4th, rotation indicator, convenient maintenance have integrally been made in the end wall side of nut of the invention
Personnel have found rapidly the screw of loosening and tighten it again in time in education.
5th, automobile using waterproof of the invention, which is put, moves back screw surface and is coated with antirust coat, effectively prevents
Its surface oxidisation.
Brief description of the drawings
Fig. 1 is the overall structure diagram of the present invention；
Fig. 2 is the top view of the present invention.
Embodiment
The embodiment of the present invention is described in further detail below in conjunction with accompanying drawing：
A kind of automobile-used anti-back Water-proof screw, as depicted in figs. 1 and 2, including integrally formed spiral shell
Cap 1, screw rod 4 and guide head 6；Annular waterproof boss is made under the nut bottom surface is coaxial
2；The screw rod is provided with screw thread and is evenly equipped with several longitudinal anti-back slots around screw rod circumferential surface
5；The anti-back slot is skewed slot, and its width is 0.2-0.3mm；At the top of the nut on end face
Uniformly it is provided with four circular theft-proof grooves 7；Rotation is integrally made in the end wall side of the nut
Indicator 3, facilitate maintainer quickly to judge whether screw produces and loosen and tightened；Institute
State nut, screw rod and be oriented to head surface and be coated with antirust coat.
It is emphasized that embodiment of the present invention is illustrative, rather than it is limited
, therefore the present invention includes being not limited to embodiment described in embodiment, it is every by
The other embodiment that those skilled in the art's technique according to the invention scheme is drawn, same category
In the scope of protection of the invention.
