The tire anti-skid nail solves the technical problems that an existing tire anti-skid nail is poor in anti-skid effect, if an existing nail hole is avoided, the tire is damaged seriously, and the service life of the tire is affected due to the fact that the tire anti-skid nail comprises a tire anti-skid nail body, a push block and a triangular block are staggered through an upward-moving auxiliary structure, and the tire anti-skid nail is limited by the resilience force of a limiting spring at the moment. The limiting spring drives the limiting plate and the triangular block to move towards the middle of the hollow frame, meanwhile, the limiting clamping rod moves towards the middle of the hollow frame along with the triangular block, the tip end of the limiting clamping rod is gradually disengaged from the nail body, the hollow frame can be directly pulled out of the nail body without being restrained, and the nail head extending out of the tire can be detached and replaced conveniently.

Description

Technical Field

[0001] The utility model relates to the technical field of tire anti-skid spikes, in particular to improved tire anti-skid spikes. Background Art

[0002] Tire studs are tire accessories that are directly embedded in the tire surface. They increase the tire's anti-skid ability and safety performance while making the tire more beautiful. They are mainly suitable for areas with long winters and thick ice and snow accumulation. They are also suitable for places where high-risk driving methods are required in harsh road conditions such as off-road and racing.

[0003] Most of the existing tire anti-skid spikes are directly driven on the tire. When the anti-skid spikes are worn and need to be replaced, the original anti-skid spikes often need to be pulled out. However, the original nail holes for installing the anti-skid spikes are easily worn out. The anti-skid spikes that are continued to be driven into the original nail holes are not strong enough and the anti-skid effect is poor. If the anti-skid spikes are driven elsewhere on the tire avoiding the existing nail holes, the tire will be greatly damaged and the tire life will be affected. In view of this, we propose an improved tire anti-skid spike. Utility Model Content

[0004] The utility model aims to overcome the deficiencies of the prior art, meet the actual needs, and provide an improved tire anti-skid spike to solve the technical problem that the existing tire anti-skid spikes are mostly directly driven on the tire. When the anti-skid spikes are worn and need to be replaced, the original anti-skid spikes often need to be pulled out. However, the original nail holes for installing the anti-skid spikes are easily worn out, and the anti-skid spikes that are continued to be driven into the original nail holes of the anti-skid spikes are not strong enough and the anti-skid effect is poor. If the anti-skid spikes are driven elsewhere on the tire avoiding the existing nail holes, the tire will be greatly damaged, which will affect the life of the tire.

[0005] In order to achieve the purpose of the utility model, the technical solution adopted by the utility model is: designing an improved tire anti-skid spike, including a tire anti-skid spike body, an auxiliary structure is arranged inside the tire anti-skid spike body, and a limiting mechanism is arranged at the bottom of the auxiliary structure;

[0006] The limiting mechanism includes a triangular block, which is attached to the side of the auxiliary structure. The side of the triangular block away from the auxiliary structure is connected to a limiting clamping rod. The bottom of the triangular block is fixedly connected to a limiting plate. A fixing rod passes through the inside of the limiting plate. One side of the limiting plate is connected to a limiting spring.

[0007] Preferably, the fixing rod is fixedly connected to the tire anti-skid stud body, and the limiting plate forms an elastic structure with the tire anti-skid stud body via a limiting spring.

[0008] Preferably, the tire anti-skid spike body comprises a spike head, a hollow frame is fixedly connected to the bottom of the spike head, and a spike body is attached to the outside of the hollow frame.

[0009] Preferably, the tip of the limit clamp rod passes through the hollow frame and is clamped in the interior of the nail body, and the nail head is made of alloy steel.

[0010] Preferably, the auxiliary structure includes a movable plate, the movable plate is engaged with the inside of the nail head, a buckle groove is provided inside the movable plate, a vertical pole is fixedly connected to the bottom of the movable plate, a return spring is sleeved on the outside of the vertical pole, and a push block is fixedly connected to the bottom of the vertical pole.

[0011] Preferably, two ends of the return spring are fixedly connected to the movable plate and the nail head respectively, and the movable plate forms an elastic structure with the return spring and the nail head.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The utility model dislocates the push block and the triangular block by moving the auxiliary structure upward. At this time, under the influence of the rebound force of the limiting spring, the limiting spring drives the limiting plate and the triangular block to move toward the middle of the hollow frame. At the same time, the limiting clamping rod also moves toward the middle of the hollow frame with the triangular block. The tip of the limiting clamping rod gradually separates from the nail body, so that the hollow frame is not constrained and can be directly pulled out of the nail body, which is convenient for disassembly and replacement of the nail head extending out of the tire.

[0014] 2. In the utility model, the original integrated tire anti-skid spike body is designed to be modular, which is convenient for partial disassembly and replacement of the tire anti-skid spike body, thereby reducing the replacement cost and eliminating the need to pull the spike body out of the tire, thereby improving convenience.

[0015] 3. In the utility model, since the hardness of the reset spring is greater than that of the limit spring, the movable plate drives the vertical rod and the push block to squeeze a group of triangular blocks under the normal state of the reset spring. At this time, the limit spring contracts. When the buckle groove is hooked by an external hook to drive the movable plate to move outward, the reset spring is effectively stretched, and the vertical rod and the push block move up at the same time, and a group of triangular blocks effectively move closer to the middle of the hollow frame.

[0024] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0025] Improved tire studs, see Figures 1 to 4 , comprising a tire anti-skid stud body 1, an auxiliary structure 2 is provided inside the tire anti-skid stud body 1, and a limiting mechanism 3 is provided at the bottom of the auxiliary structure 2;

[0026] The limiting mechanism 3 includes a triangular block 301, which is attached to the side of the auxiliary structure 2. The side of the triangular block 301 away from the auxiliary structure 2 is connected to a limiting clamping rod 302. The bottom of the triangular block 301 is fixedly connected to a limiting plate 303. A fixing rod 304 runs through the inside of the limiting plate 303. A limiting spring 305 is connected to one side of the limiting plate 303, wherein the fixing rod 304 and the tire anti-skid stud body 1 are fixedly connected, and the limiting plate 303 forms an elastic structure with the tire anti-skid stud body 1 through the limiting spring 305. The utility model moves the auxiliary structure 2 upward so that the push block 205 and the triangular block 301 are misaligned. At this time, under the influence of the rebound force of the limiting spring 305, the limiting spring 305 drives the limiting plate 303 and the triangular block 301 to move toward the middle of the hollow frame 102. At the same time, the limiting clamping rod 302 also moves toward the middle of the hollow frame 102 with the triangular block 301. The tip of the limiting clamping rod 302 gradually separates from the nail body 103, so that the hollow frame 102 is not constrained and can be directly pulled out of the nail body 103, which is convenient for disassembly and replacement of the nail head 101 extending out of the tire.

[0027] It is worth noting that the tire anti-skid spike body 1 includes a spike head 101, a hollow frame 102 is fixedly connected to the bottom of the spike head 101, a spike body 103 is attached to the outside of the hollow frame 102, wherein the tip of the limit clamping rod 302 passes through the hollow frame 102 and is engaged with the inside of the spike body 103, and the material of the spike head 101 is alloy steel. In the utility model, the original integrated tire anti-skid spike body 1 is designed to be modular, which is convenient for partial disassembly and replacement of the tire anti-skid spike body 1, reducing the replacement cost while not needing to pull the spike body 103 out of the tire, thereby improving convenience.

[0028] It is worth mentioning that the auxiliary structure 2 includes a movable plate 201, which is engaged in the nail head 101. A buckle groove 202 is provided inside the movable plate 201. A vertical rod 203 is fixedly connected to the bottom of the movable plate 201. A reset spring 204 is sleeved on the outside of the vertical rod 203, wherein the two ends of the reset spring 204 are respectively fixedly connected to the movable plate 201 and the nail head 101. The movable plate 201 forms an elastic structure with the nail head 101 through the reset spring 204, and a push block 205 is fixedly connected to the bottom of the vertical rod 203. In the utility model, since the hardness of the return spring 204 is greater than that of the limit spring 305, the movable plate 201 drives the vertical rod 203 and the push block 205 to squeeze a group of triangular blocks 301 under the normal state of the return spring 204. At this time, the limit spring 305 contracts. When the buckle groove 202 is hooked by an external hook-like tool to drive the movable plate 201 to move outward, the return spring 204 is effectively stretched, and the vertical rod 203 and the push block 205 move upward at the same time, and the group of triangular blocks 301 effectively move closer to the middle of the hollow frame 102.

[0029] Working principle: A plurality of tire anti-skid spike bodies 1 are driven into the tire surface to increase the tire anti-skid ability. When the nail head 101 of the tire anti-skid spike body 1 is worn, the buckle groove 202 is hooked with the help of external hooks to drive the movable plate 201 to move outward. At this time, the reset spring 204 is stretched, and the vertical rod 203 and the push block 205 are moved upward, so that the push block 205 is misaligned with the triangular block 301. Under the influence of the rebound force of the limiting spring 305, a group of triangular blocks 301 move closer to the middle of the hollow frame 102, and the limiting clamp rod 303 is moved upward. 02 also moves with the triangular block 301 toward the middle of the hollow frame 102, and the tip of the limiting rod 302 gradually separates from the nail body 103, so that the hollow frame 102 can be directly pulled out of the nail body 103 without constraint, which is convenient for disassembly and replacement of the nail head 101 extending out of the tire. The utility model designs the original integrated tire anti-skid nail body 1 into a modular type, which is convenient for partial disassembly and replacement of the tire anti-skid nail body 1, thereby reducing the replacement cost and eliminating the need to pull the nail body 103 out of the tire, thereby improving convenience.
