Detailed Description
The present invention will be further described with reference to the accompanying drawings and the following detailed description.
A combination antitheft screw as shown in fig. 1 and fig. 2, a combination antitheft screw characterized in that: the anti-theft screw comprises an anti-theft screw 100 and a matching rotary head 200, wherein a special-shaped sunk platform 103 is arranged at one end of the anti-theft screw 100, a special-shaped boss 204 and an outer hexagonal boss 202 are respectively arranged at two ends of the matching rotary head 200, the special-shaped boss 204 is matched with the special-shaped sunk platform 103, and a sunk groove 205 is formed in the outer hexagonal boss 202. The arrangement of the sinking platform at the upper end of the anti-theft screw 100 will not affect the stability of the screw, especially the thread structure. When the matching rotor 200 is clamped into the anti-theft screw 100, the anti-theft screw 100 can be screwed by using tools such as a cross, a straight line, a wrench and the like, and the matching rotor 200 which is small in size and convenient to carry can be used for mounting and dismounting screws by using various tools. The combined anti-theft screw has the advantages that the structure is stable, the matched and rotated nut is small in size and easy to carry when the anti-theft screw is used for preventing theft, and the screw can be disassembled and assembled by using various common tools, so that the use is convenient.
On the basis of the above, as shown in fig. 1, the upper end of the anti-theft screw 100 is provided with a cylinder 101, the special-shaped sunken platform 103 is arranged in the cylinder 101, and the thickness of the cylinder 101 is greater than the depth of the special-shaped sunken platform 103. The arrangement of the special-shaped sinking platform 103 in the thicker cylinder does not affect the structural stability of the anti-theft screw 100. The whole structure of the special-shaped sinking platform 103 is in the cylinder 101, the cylinder has enough thickness and an outer cylindrical surface to wrap the special-shaped sinking platform 103, and the situation that a screw is damaged is not easy to occur when the special-shaped sinking platform is used.
On the basis, as shown in fig. 1, the special-shaped sinking platform 103 is not structurally matched with the commercial flow screw disassembling tool. The screw can not be screwed by a common tool for disassembling the screw, and the anti-theft effect can be achieved. When in use, the antitheft screw 200 can be operated only by using the matched matching rotary head 200 component, thereby effectively ensuring the antitheft performance of the antitheft screw.
On the basis of the above, as shown in fig. 1, an outer hexagonal boss 202 is provided on the upper surface 201 of the matching rotor 200. After the matching rotor 200 is engaged with the antitheft screw 100, the antitheft screw 100 can be assembled and disassembled by using a tool such as a wrench which can operate an external hexagonal screw.
On the basis, as shown in fig. 1, the outer hexagonal boss 202 is provided with a sinking groove 205, the depth of the sinking groove 205 is half of the thickness of the outer hexagonal boss 202, and the sinking groove 205 is a cross and straight combined groove. The depth of the undercut 205 is only half of the thickness of the outer hexagonal boss 202, and the structural integrity of the outer hexagonal boss 202 is not affected. After the matching rotor 200 is snapped into the antitheft screw 100, the antitheft screw 100 can be assembled and disassembled by using a cross screwdriver and a straight screwdriver.
On the basis, as shown in fig. 1 and 2, the lower surface 203 of the matching swivel 200 is provided with a special-shaped boss 204, the special-shaped boss 204 is matched with the special-shaped sinking platform 103 in structure, and the special-shaped boss 204 can be just clamped into the special-shaped sinking platform 103. The matching rotary head 200 and the antitheft screw 100 can be perfectly matched for use. The depth of the special-shaped sunken table 103 is the same as the thickness of the special-shaped boss 204, so that the effects of firmness and material and space saving are achieved.
On the basis of the above, as shown in fig. 1, the outer diameter of the anti-theft screw 100 is the same as the outer diameter of the matching rotor 200. Has enough firmness and does not influence the use of the antitheft screw 100 in the hole. When the outer diameter of the antitheft screw 100 is larger than the outer diameter of the matching rotor 200, the matching rotor 200 is easily damaged by applying a force to the antitheft screw 100 through the matching rotor 200. When the outer diameter of the anti-theft screw 100 is smaller than the outer diameter of the matching rotor 200, the anti-theft screw 100 is installed in a hole slightly larger than the diameter of the anti-theft screw 100, and the matching rotor cannot be used.
The above-mentioned embodiments, further detailed description of the objects, technical solutions and advantages of the present invention, it should be understood that the above-mentioned embodiments are only specific embodiments of the present invention, and are not intended to limit the present invention, and any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the scope of the present invention.
