Abstract
The invention relates to an antitheft screw assembly which comprises a bolt and a nut. The bolt and the nut are provided with matched threads. A vertical first hollow core is arranged in the middle of the upper end of the bolt, and an arc-shaped second hollow core is arranged below the first hollow core. The first hollow core and the second hollow core communicate with each other smoothly. A circular-arc-shaped pin is arranged in the second hollow core in an interference fit manner. The lower end of the pin is provided with a sharp end. A groove matched with the sharp end is formed in the side face of the inner wall of the nut. An opening in the lower end of the second hollow core is formed in the left side of the bolt. The first hollow core deviates towards the right side of the center of the bolt. The antitheft screw assembly has the beneficial effects of being simple in structure, good in antitheft effect and easy to mount.
Description
Technical field
The present invention 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 more, but it has the shortcoming 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 the present invention is aiming at disadvantages mentioned above, it is provided that a kind of simple in construction, good anti-theft effect, installation are easy to anti-theft screw assembly。
The technical scheme is that and be achieved in that: anti-theft screw assembly, including screw bolt and nut, they have the screw thread of cooperation, it is characterized in that: in the middle of described bolt upper end, have the first vertical hollow, first hollow is presented herein below arc the second hollow, 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 the right side of bolt-center。
The invention has the beneficial effects as follows: such anti-theft screw assembly has simple in construction, good anti-theft effect, the easy advantage of installation。Described pin lower end has tip, and described screw inwall side has the groove coordinating tip, has the better advantage of anti-theft 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, has the advantage being easily installed。
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention。
Wherein: 1, bolt 2, nut the 3, first hollow the 4, second hollow 5, pin 6, most advanced and sophisticated 7, groove。
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described。
As 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: in the middle of described bolt upper end, have the first vertical hollow 3, first hollow is presented herein below arc the second hollow 4, the first hollow and the smooth connection of the second hollow, has 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, head part upper end is pounded with hammer, head part lower end heads on pin, and pin acts on the side of nut, it is possible to play antitheft effect, such screw assembly is especially suitable for the screw of the unified specification of large quantities of installation, for instance the guide rail of railway is first-class。
Saying further, described pin lower end has most advanced and sophisticated 6, and such pin heads on nut side, fixing better effects if。
Saying further, described nut inner wall side has the groove 7 coordinating tip。Such anti-theft effect is better。
Saying further, 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, so can arrange longer by the second hollow, and the curvature of annulus is less, and result of use is better。
The foregoing is only specific embodiments of the invention, but the architectural feature of the present invention is not limited to this, any those skilled in the art is in the field of the invention, and change or the modification made all are encompassed in the scope of the claims of the present invention。
Claims (5)
1. anti-theft screw assembly, including screw bolt and nut, they have the screw thread of cooperation, it is characterized in that: in the middle of described bolt upper end, have the first vertical hollow, first hollow is presented herein below arc the second hollow, first hollow and the smooth connection of the second hollow, have the circular arc pin of interference fit inside the second hollow。
2. anti-theft screw assembly according to claim 1, is characterized in that: described pin lower end has tip。
3. anti-theft screw assembly according to claim 1 and 2, is characterized in that: described nut inner wall side has the groove coordinating tip。
