Abstract
The utility model relates to an automobile -usedly prevent moving back waterproof screw, nut, screw rod and direction head including integrated into one piece, its technical characterstic lies in: the nut bottom surface is coaxial makes annular waterproof boss downwards, it has several vertically to prevent moving back the groove to be equipped with the screw on the screw rod and to surround screw rod circumference surface equipartition. The utility model discloses an it has several vertically to prevent moving back the groove to be equipped with the screw on the screw rod and to surround screw rod circumference surface equipartition, to prevent moving back the groove and be the chute, is its width 0.2 0.3mm. Should prevent moving back the chute and have the effect that prevents the not hard up back of screw and deviate from from the screw in, and encircle screw rod circumference surface equipartition and prevent vertically moving back the chute, it is long vertically to prevent moving back chute length, for only preventing what the connecting portion of nut and screw rod set up several straight flutes that to move back the effect better.
Description
Technical field
This utility model 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 requisite automobile component.But because it is widely recognized
And application, for most of technical staff, lack power to its technological improvement, lead to the waterproof of automobile-used screw, anticreep with
And also there are some defects, on the means of transportation that automobile etc. is related to personal safety as well as the property safety in anti-theft, easily being screwed into property aspect
Screw used is badly in need of its waterproof, anticreep and theftproof performance are lifted further, ensures the vapour of driver and passenger
Car driving safety.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of reasonable in design, structure is simple and has
There is the automobile-used anti-back Water-proof screw of waterproof, antitheft, anti-back and antirust function.
This utility model solves its technical problem and takes technical scheme below to realize：
A kind of automobile-used anti-back Water-proof screw, including integrally formed nut, screw rod and guide head；Described nut bottom surface is coaxial
Make downwards annular waterproof boss；Described screw rod is provided with screw thread and is evenly equipped with several longitudinal anti-backs around screw rod circumferential surface
Groove.
And, described anti-back slot is skewed slot, and its width is 0.2-0.3mm.
And, described nut top end face uniformly has four circular theft-proof grooves.
And, rotation indicator has integrally been made in the end wall side of described nut.
And, described nut, screw rod and guiding head surface are all coated with antirust coat.
Advantage of the present utility model and good effect are：
1st, make annular waterproof boss under nut bottom surface of the present utility model is coaxial and there is waterproof action.
2nd, described screw rod of the present utility model is provided with screw thread and is evenly equipped with several longitudinal anti-backs around screw rod circumferential surface
Groove；Described anti-back slot is skewed slot, and its width is 0.2-0.3mm.This anti-back skewed slot have prevent de- in screw after screw loosening
The effect going out, all deploys troops on garrison duty around screw rod circumferential surface and longitudinally moves back skewed slot, this longitudinal anti-back chute length is long, with respect to only in nut
The anti-back effect arranging several straight troughs with the connecting portion of screw rod is more preferable.
3rd, uniformly have four circular theft-proof grooves on the end face of nut top described in the utility model, special tooling need to be adopted
Could be backed out, be there is anti-theft；And uniformly have four circular grooves, automobile inspection personnel due on the end face of nut top
When needing knockout screw because of maintenance, maintainer is facilitated quickly to unload cartridge screw using special tooling, time saving and energy saving.
4th, rotation indicator has integrally been made in the end wall side of nut of the present utility model, facilitates maintainer in education
When, it is simultaneously tightened by rapid discovery loosens in time screw again.
5th, automobile waterproof of the present utility model is put and is moved back screw surface and be coated with antirust coat, effectively prevents its surface oxidisation.
Brief description
Fig. 1 is overall structure diagram of the present utility model；
Fig. 2 is top view of the present utility model.
Specific embodiment
Below in conjunction with accompanying drawing, this utility model embodiment is described in further detail：
A kind of automobile-used anti-back Water-proof screw, as depicted in figs. 1 and 2, including integrally formed nut 1, screw rod 4 and guide head
6；Annular waterproof boss 2 is made under described nut bottom surface is coaxial；Described screw rod is provided with screw thread and around screw rod circumferential surface
It is evenly equipped with several longitudinal anti-back slots 5；Described anti-back slot is skewed slot, and its width is 0.2-0.3mm；On the end face of described nut top all
Cloth has four circular theft-proof grooves 7；Rotation indicator 3 has integrally been made in the end wall side of described nut, facilitates maintainer
Whether quick judgement screw produces and loosens and tightened；Described nut, screw rod and guiding head surface are all coated with antirust coat.
It is emphasized that embodiment described in the utility model is illustrative rather than determinate, therefore this reality
It is not limited to the embodiment described in specific embodiment with new inclusion, every new according to this practicality by those skilled in the art
The other embodiment that the technical scheme of type draws, also belongs to the scope of this utility model protection.
