Description

Technical Field

[0001] This utility model belongs to the field of tire puncture prevention technology, and particularly relates to a double-insurance device for preventing punctures in bicycle tires. Background Technology

[0002] With the development of the times, transportation tools are becoming more and more advanced. Cars are the main means of transportation for families. At present, fewer and fewer people ride bicycles. The largest groups are primary school students and the elderly. Primary school students use them to go to and from school, while the elderly use them for leisure and fitness. Bicycles are a preferred means of transportation for primary school students and the elderly because they are green, environmentally friendly, and energy-saving. However, the biggest drawback of riding bicycles is that the tires are easily punctured by nails.

[0003] The existing utility model with authorization announcement number CN216443422U discloses an anti-puncture tire component, including a tire body and a wheel hub body. The tire body is fitted onto the outer wall of the wheel hub body. An anti-puncture mechanism is located at the outer end of the wheel hub body and includes a support plate. Two sets of support plates are provided, and the sides of the support plates that are close to each other are movably connected to the front and rear ends of the wheel hub body through bearings. Guide plates are fixed to the lower side of one side of each set of support plates, and the guide plates are located on the front and rear sides of the wheel hub body. The two sets of guide plates are designed in a figure-eight shape. A connecting plate is provided at the top of the guide plate, and fixing components are provided on both sides of the top of the connecting plate. A support mechanism is located between the guide plate and the connecting plate and includes a rotating block.

[0004] By adopting the above technical solution, this utility model can reduce the probability of the tire body being punctured, effectively protect the tire body, and thus improve the service life of the tire body. However, the middle of the figure-eight design of the above technical solution still cannot be cleaned, and there are more installed parts, which increases the overall weight and resistance, and also increases the production cost. Therefore, it is still impossible to avoid the problem of tires being punctured by nails while riding. In addition, if the parts of the above technical solution do not fit well, jamming can easily occur, posing a significant safety hazard.

[0005] Therefore, we propose a double-safety device for puncture-proof bicycle tires to solve the above problems. Utility Model Content

A second mounting bracket is fixedly connected to the upper surface of the magnet box, and a curved rod bracket is fixedly connected to the upper surface of the second mounting bracket. Two magnet blocks are snapped into the inner wall of the magnet box. A base support bracket is fitted onto the outer surface of the magnet box, and several bolts are provided on the outer side of the base support bracket. The ends of each group of bolts close to each other penetrate the base support bracket and are threadedly connected to the inner wall of the magnet box. A limit bracket is fixedly connected to the end of the curved rod bracket away from the second mounting bracket.

[0009] Preferably, the outer side of the magnet box is provided with a wheel rim, and the inner wall of the wheel rim is rotatably connected to a central shaft.

[0010] Preferably, two support frames are fitted on the outer surface of the central shaft, and a shock-absorbing rod is fixedly connected to the upper surface of each support frame.

[0011] Preferably, a connecting bridge is provided above the wheel rim, and the upper surfaces of the two shock absorber rods are fixedly connected to the bottom surface of the connecting bridge.

[0012] Preferably, each of the shock absorber rods has a mounting base fixedly connected to its outer surface, and two mounting bases have mudguards fixedly connected to their outer surfaces. The outer surface of the mudguards is fixedly connected to the outer surface of the limiting frame.

[0013] Preferably, a brake pad is fixedly connected to the outer surface of the wheel rim, and a brake is provided on the outer side of the brake pad.

[0014] Preferably, the outer surface of the central shaft is threaded with four threaded caps, and the side of each set of threaded caps that is close to each other is in contact with the outer surface of the support rod.

[0015] In summary, the technical effects and advantages of this utility model are as follows:

[0023] Reference Figures 1-4 This embodiment provides a double-insurance device for preventing punctures in bicycle tires. The double-insurance device for preventing punctures in bicycle tires includes a magnet box 1. Two first mounting brackets 2 are fixedly connected to the back of the magnet box 1. A rim 10 is provided on the outer side of the magnet box 1. A central axle 11 is rotatably connected to the inner wall of the rim 10. The rim 10 contacts the ground to support the magnetic device. The central axle 11 can rotate in conjunction with the rim 10.

[0024] Each first mounting bracket 2 has a support rod 3 fixedly connected to its back. The upper surface of the magnet box 1 has a second mounting bracket 4 fixedly connected to it. The outer surface of the central shaft 11 is fitted with two support brackets 12. The upper surface of each support bracket 12 has a shock-absorbing rod 13 fixedly connected to it. The support bracket 12 can support the shock-absorbing rod 13, and the support bracket 12 has the effect of saving space.

[0025] The upper surface of the second mounting bracket 4 is fixedly connected to the bent rod bracket 5. The inner wall of the magnet box 1 is fitted with two magnet blocks 6. A connecting bridge 14 is provided above the wheel rim 10. The upper surfaces of the two shock absorber rods 13 are fixedly connected to the bottom surface of the connecting bridge 14. The connecting bridge 14 is used for the two shock absorber rods 13 to play a stabilizing role.

[0026] The outer surface of the magnet box 1 is fitted with a base bracket 7. Several bolts 8 are provided on the outer side of the base bracket 7. The outer surface of each shock absorber rod 13 is fixedly connected with a mounting base 15. The outer surfaces of the two mounting bases 15 are jointly fixedly connected with mudguards 16. The outer surface of the mudguards 16 is fixedly connected to the outer surface of the limiting frame 9. The mudguards 16 are supported by the two mounting bases 15, and the limiting frame 9 can be supported by the mudguards 16.

[0027] The ends of each bolt group 8 that are close to each other pass through the base bracket 7 and are threaded to the inner wall of the magnet box 1. The end of the bent rod bracket 5 that is away from the second mounting bracket 4 is fixedly connected to the limit bracket 9. The outer surface of the wheel rim 10 is fixedly connected to the brake pad 17. The brake brake 18 is provided on the outer side of the brake pad 17.

[0029] The working principle of this utility model is as follows: In use, firstly, the limiting frame 9 is installed on the mudguard 16. Then, the fixed connection between the limiting frame 9 and the bending rod frame 5 is used to ensure the stability of the bending rod frame 5. Two support rods 3 are installed on the outer surface of the central shaft 11 to ensure its stability. Two threaded caps 19 are used to further ensure the stability of the support rods 3. At this time, the connection between the first mounting frame 2 and the magnet box 1, and the fixed connection between the first mounting frame 2 and the support rods 3, ensure the stability of the magnet box 1. The bottom bracket 7 can prevent the magnet blocks 6 from falling out. Several bolts 8 are used to install the bottom bracket 7 on the magnet box 1. If there are iron nails on the road ahead during riding, they will be attracted by the two magnet blocks 6 when they are about to contact the tire, and will remain attracted to the bottom surface of the magnet blocks 6, thus avoiding the problem of iron nails puncturing the tire.
