Description
Technical Field
[0001] The utility model relates to the technical field of tire anti-skid spikes, in particular to a novel automobile tire anti-skid spike. Background Art
[0002] Some cars that often go to mountainous areas usually have anti-skid spikes installed on the outer wall of their tires to increase the anti-skid strength of the outer wall of the car tires, prevent the tires from slipping when driving on mountainous areas, and ensure the safety of the car driving on mountainous areas.
[0003] After long-term use of automobile tire anti-skid spikes, the anti-skid spike cone at the bottom will be severely worn. At this time, the entire anti-skid spike needs to be replaced. Since it is difficult to replace the anti-skid spike cone at the bottom of the existing anti-skid spikes alone, it will lead to a waste of resources of other useful components. In view of the above situation, technical innovation is carried out based on the existing automobile tire anti-skid spikes. Utility Model Content
[0004] The utility model aims to provide a novel anti-skid spike for automobile tires to solve the problems raised in the above-mentioned background technology.
[0005] To achieve the above purpose, the utility model provides the following technical solution: a new type of anti-skid stud for automobile tires, comprising:
[0006] The anti-skid nail column has a slot on its outer side wall and an anti-skid nail cone is placed at the bottom of the anti-skid nail column, wherein:
[0007] A screw is provided at the top of the anti-skid spike cone, and insertion holes are provided at the top of the screw and the anti-skid spike cone. A mounting hole is provided at the front side of the anti-skid spike cone. A first threaded hole is provided at the bottom of the anti-skid spike column. A positioning pin is provided at the top of the first threaded hole, and a second threaded hole is provided at the front side of the positioning pin. The second threaded hole is aligned with the mounting hole, and the second threaded hole is connected with the insertion hole of the anti-skid spike cone.
[0008] Preferably, the screw is threaded into the first threaded hole, and the positioning pin is inserted into the insertion holes of the screw and the anti-slip spike cone.
[0009] Preferably, a cross bolt is provided in the mounting hole, and the cross bolt is threadedly connected to the second threaded hole.
[0010] Preferably, a first sealing ring is provided in the mounting hole, and the first sealing ring is located on the outer ring of the cross bolt.
[0011] Preferably, a second sealing ring is provided on the top of the anti-slip spike cone, and the second sealing ring is located on the outer ring of the screw.
[0012] Preferably, the top of the second sealing ring fits with the bottom of the anti-slip nail column, and the inner side wall of the first sealing ring fits with the outer side wall of the cross bolt.
[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0014] The utility model evenly opens mounting holes on the automobile tires, and inserts the anti-skid spikes into the mounting holes. Since the automobile tires are made of rubber and have elasticity, when the anti-skid spikes are inserted into the mounting holes, they are squeezed and tightly fixed in the mounting holes. The contact surface of the anti-skid spikes can be increased through the clamping grooves, thereby improving the installation stability of the anti-skid spikes.
[0015] The anti-skid spike cone is fixed to the bottom of the anti-skid spike column by a screw rod, and the positioning pin is fixed in the insertion hole of the anti-skid spike cone and the screw rod by a cross bolt. The anti-skid spike cone can be stably fixed to the bottom of the anti-skid spike column by the mutual cooperation of the screw rod and the cross bolt, thereby improving the integral stability of the anti-skid spike;
[0016] When the anti-skid spike cone needs to be replaced due to wear, it is only necessary to unscrew the cross bolt first, and then unscrew the anti-skid spike cone connecting screw, so as to achieve the effect of convenient replacement of the anti-skid spike cone;
[0017] The first sealing ring can prevent dirt from entering the connection between the cross bolt and the mounting hole of the anti-skid spike cone, thereby improving the ease of disassembly and assembly of the cross bolt. The second sealing ring can prevent dirt from entering the connection between the screw rod and the first threaded hole of the anti-skid spike column, thereby improving the ease of disassembly and assembly of the screw rod.
