Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of toothed bolts, in particular to an anti-theft external hexagonal flange-faced toothed bolt. Background Art
[0002] At present, most anti-theft bolts use conical external threads in conjunction with special tools. They can only be tightened by applying force clockwise. If they are disassembled by applying force counterclockwise, the tool will fall off. The conical shape effectively avoids the possibility of disassembly with pipe wrenches, thereby achieving a better anti-theft and unloading effect. The current anti-theft external hexagonal flange-face toothed bolts have low strength and are prone to cracking and damage when the bolts are twisted. Therefore, we propose an anti-theft external hexagonal flange-face toothed bolt. Utility Model Content
[0003] The purpose of the utility model is to provide an anti-theft external hexagonal flange-faced toothed bolt to solve the problems raised in the above-mentioned background technology.
[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solution: an anti-theft external hexagonal flange toothed bolt, comprising a screw, an external thread is provided below the outer side wall of the screw, a hexagonal bolt head is provided at one end of the screw, a gasket is provided at the bottom of the hexagonal bolt head, three groups of second reinforcing ribs are provided inside the screw, third reinforcing ribs are provided on the outer sides of each of the three groups of second reinforcing ribs, and reinforcing frames are provided on the outer sides of the three groups of second reinforcing ribs.
[0005] Furthermore, a fourth reinforcing rib is provided inside the screw rod, and an outer side wall of the fourth reinforcing rib is in contact with an inner side wall of the reinforcing frame.
[0006] Furthermore, the outer side walls of the reinforcement frame are each provided with three groups of first reinforcement ribs, and one ends of the three groups of first reinforcement ribs are respectively connected to the inner side walls of the three groups of third reinforcement ribs.
[0007] Furthermore, the reinforcement frame is arranged in a triangular shape.
[0008] Furthermore, the third reinforcing rib is arranged in an arc shape.
[0009] Furthermore, three groups of the second reinforcing ribs are distributed in a ring array inside the screw.
[0010] Compared with the prior art, the beneficial effect of the present invention is that the present invention can improve the overall strength of the bolt through the cooperation of the first reinforcing rib, the second reinforcing rib, the third reinforcing rib, the fourth reinforcing rib and the reinforcing frame, so that the bolt will not easily crack or be damaged when subjected to torsion.
