Abstract
The utility model relates to an antitheft screw subassembly, the name is antitheft screw subassembly, including the screw bolt and nut, they have a complex screw thread, bolt upper end in the middle of have vertical first hollow, be arc second hollow below the first hollow, first hollow and second hollow be in the same direction as smooth intercommunication, has the convex of interference fit to pin in that the second hollow is inside, the pin lower extreme pointed end has, inner wall of nut side the most advanced recess of cooperation has, second hollow lower extreme opening in the left side of bolt, the right side at first hollow erroneous tendency bolt center. Such antitheft screw subassembly have simple structure, theftproof effectual, install easy advantage.
Description
Technical field
This utility model relates to anti-theft screw assembly.
Background technology
Screw assembly includes screw bolt and nut, and they have the screw thread of cooperation；In prior art, although anti-theft screw is relatively
Many, but it has the shortcomings such as structure complexity, poor, the installation difficulty of anti-theft effect, have impact on the use of anti-theft screw.
Summary of the invention
The purpose of this utility model is aiming at disadvantages mentioned above, it is provided that a kind of simple in construction, good anti-theft effect, installation are easy
Anti-theft screw assembly.
The technical solution of the utility model is achieved in that anti-theft screw assembly, and including screw bolt and nut, they have
The screw thread coordinated, is characterized in that: having the first vertical hollow in the middle of described bolt upper end, the first hollow is presented herein below arc second
Hollow, the first hollow and the smooth connection of the second hollow, have the circular arc pin of interference fit inside the second hollow.
Saying further, described pin lower end has tip.
Saying further, described nut inner wall side has the groove coordinating tip.
Saying further, the second described hollow lower ending opening is in the left side of bolt, and the first hollow is partial to bolt-center
Right side.
The beneficial effects of the utility model are: such anti-theft screw assembly has simple in construction, good anti-theft effect, installation
Readily advantage.Described pin lower end has tip, and described screw inwall side has the groove coordinating tip, has anti-
Steal the more preferable advantage of effect；The second described hollow lower ending opening is in the left side of bolt, and the first hollow is partial to the right side of bolt-center
Side, has the advantage being easily installed.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein: 1, bolt 2, nut the 3, first hollow the 4, second hollow 5, pin 6, tip 7, groove.
Detailed description of the invention
The utility model will be further described below in conjunction with the accompanying drawings.
As it is shown in figure 1, anti-theft screw assembly, including bolt 1 and nut 2, they have the screw thread of cooperation, it is characterized in that:
Having the first vertical hollow 3 in the middle of described bolt upper end, the first hollow is presented herein below arc the second hollow 4, the first hollow and
The two smooth connections of hollow, have the circular arc pin 5 of interference fit inside the second hollow.
So, after this nut is arranged on bolt, can be placed on inside the first hollow with head part, pound on head part with hammer
End, head part lower end heads on pin, and pin acts on the side of nut, can play antitheft effect, and such screw assembly is non-
Often being suitable for the screw of the unified specification of large quantities of installations, the guide rail of such as railway is first-class.
Saying further, described pin lower end has most advanced and sophisticated 6, and such pin heads on nut side, and fixing effect is more
Good.
Saying further, described nut inner wall side has the groove 7 coordinating tip.So anti-theft effect is more preferable.
Saying further, the second described hollow lower ending opening is in the left side of bolt, and the first hollow is partial to bolt-center
Right side, so can arrange longer by the second hollow, and the curvature of annulus is less, and using effect is more preferable.
The foregoing is only specific embodiment of the utility model, but architectural feature of the present utility model be not limited to this,
Any those skilled in the art is in field of the present utility model, and change or the modification made all are contained of the present utility model
In the scope of the claims.
