Description

Technical Field

[0001] This utility model belongs to the field of protective devices, specifically relating to a tire inflation protection device. Background Technology

[0002] A tire is a ring-shaped, elastic rubber product mounted on a metal rim, typically fitted onto various vehicles or machinery to achieve contact with the road surface and ensure vehicle performance. Tires play a crucial role in vehicle operation, primarily in the following aspects: 1) The tire is the only point of contact between the vehicle and the ground, therefore it must be able to withstand the vehicle's full weight and load. Proper tire design and material selection ensure that the tire maintains stable shape and performance under heavy pressure; 2) The friction between the tire and the ground is the source of the vehicle's forward momentum and is also key to slowing down during braking. The tire's material and tread design affect its friction with the ground, thus influencing the vehicle's traction and braking performance; 3) Tires possess a certain degree of elasticity, absorbing impacts and vibrations from the road surface, thereby protecting the vehicle and passengers from bumps and shocks. This contributes to improved ride comfort and reduced wear on vehicle components; 4) The tire's tread design affects the vehicle's handling performance and driving stability. For example, using appropriate tread patterns and widths can improve vehicle grip and handling, making the vehicle more stable at high speeds and during sharp turns; 5) Different types of tires are suitable for different road conditions. For example, highway tires are suitable for paved roads, while off-road tires are suitable for rough and uneven off-road conditions.

[0003] With the rapid development of vehicles, tire inflation operations have become more frequent. However, tire blowouts can occur during inflation, posing a serious threat to the lives of workers. Therefore, a protective device is needed to protect the lives of workers during tire inflation. Utility Model Content

[0004] The purpose of this invention is to address the serious threat to the life safety of workers caused by tire blowouts during the inflation process. This invention proposes a tire inflation protection device that can restrict tire inflation and prevent blowouts from posing a safety threat to workers. The device has good overall performance.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows: a tire inflation protection device, including a protective cage, a movable plate rotatably connected inside the protective cage, an inflation pipeline and a control switch installed on the protective cage, an air control valve provided in the inflation pipeline, the air control valve being electrically connected to the control switch, the control switch being located below the movable plate, and the movable plate being able to abut against the control switch when rotated in a direction away from the tire, a protective door installed on the protective cage, a limit block fixed inside the protective door, the side of the limit block away from the protective door being an inclined surface, the upper end of the inclined surface being inclined towards the direction close to the protective door, when the tire... When positioned between the movable plate and the limiting block, the tire can simultaneously contact both the movable plate and the limiting block. In use, first place the tire inside the protective cage, then close the protective door, causing the limiting block on the protective door to contact the tire. When the protective door is fully closed, the limiting block pushes the tire to contact the movable plate, causing the movable plate to move and contact the control switch, triggering the control switch. The control switch then opens the air circuit to begin inflating the tire. During inflation, the protective cage restricts the tire, preventing debris from flying at workers in the event of a tire blowout, thus ensuring the safety of workers. Overall, the product has a good performance.

[0006] Furthermore, the pneumatic control valve is a solenoid valve, and the control switch is a pressure switch.

[0007] Furthermore, the inflation pipeline includes an air compressor and a valve core tube. The output end of the air compressor is connected to the input end of the air circuit control valve through the air supply pipeline. The output end of the valve core tube is equipped with an air nozzle connector, and the input end of the valve core tube is connected to the output end of the air circuit control valve.

[0008] Furthermore, an electromagnetic lock is installed between the protective door and the protective cage, and the electromagnetic lock is electrically connected to the pneumatic control valve.

[0009] Furthermore, an interlock circuit is electrically connected between the electromagnetic lock and the pneumatic control valve. This interlock circuit can restrict the protective door from opening during the inflation process.

[0010] Furthermore, a valve is installed in the air supply line between the air compressor and the air circuit control valve, which can shut off the air source in time if the air circuit control valve is damaged.

[0011] As can be seen from the above technical solutions, this utility model has the following advantages:

[0012] By placing the tire inside the protective cage and then closing the protective door, the limiting block on the protective door comes into contact with the tire. When the protective door is fully closed, the limiting block pushes the tire against the movable plate, causing the movable plate to move and contact the control switch, triggering the control switch. The control switch then opens the air circuit to begin inflating the tire. During inflation, the protective cage restricts the tire, preventing debris from flying at workers in the event of a tire blowout, thus ensuring the safety of workers. Overall, the system is highly effective. Attached Figure Description

[0018] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0019] like Figure 1-2As shown, this embodiment provides a tire inflation protection device, including a protective cage 1. A movable plate 2 is rotatably connected inside the protective cage 1. An inflation pipeline and a control switch 3 are installed on the protective cage 1. The inflation pipeline is equipped with an air control valve 10, which is electrically connected to the control switch 3. The air control valve 10 is a solenoid valve, and the control switch 3 is a pressure switch. The inflation pipeline includes an air compressor 11 and a valve core air pipe 7. The output end of the air compressor 11 is connected to the input end of the air control valve 10 via an air supply pipeline. The output end of the valve core air pipe 7 is equipped with an air nozzle connector, and the input end of the valve core air pipe 7 is connected to the output end of the air control valve 10. A valve 12 is installed in the air supply pipeline between the air compressor 11 and the air control valve 10, allowing air to flow through the air control valve 10. In case of damage, the air supply should be shut off immediately. The control switch 3 is located below the movable plate 2, and the movable plate 2 can abut against the control switch 3 when it rotates away from the tire 6. A protective door 4 is installed on the protective cage 1, and an electromagnetic lock is installed between the protective door 4 and the protective cage 1. The electromagnetic lock is electrically connected to the air circuit control valve 10, and an interlock circuit is electrically connected between the electromagnetic lock and the air circuit control valve 10. The interlock circuit can restrict the protective door 4 to prevent the protective door 4 from opening during inflation. A limit block 5 is fixed on the inner side of the protective door 4. The side of the limit block 5 away from the protective door 4 is an inclined surface, and the upper end of the inclined surface is inclined towards the protective door 4. When the tire 6 is between the movable plate 2 and the limit block 5, the tire 6 can abut against both the movable plate 2 and the limit block 5 at the same time.

[0020] Specifically, such as Figure 3As shown, control switch 3 is a pressure switch. When pressure is applied, control switch 3 is triggered. During inflation, the inflation pressure of tire 6 is first set, and this signal is transmitted to control switch 3 through pressure input terminal 8. When tire 6 contacts movable plate 2 and movable plate 2 triggers control switch 3, control switch 3 is compressed by tire 6, generating pressure. This pressure is transmitted to pressure output terminal 9. Because the air pressure inside the tire is insufficient, the pressure at pressure input terminal 8 is greater than the pressure at pressure output terminal 9. At this time, control switch 3 sends a signal to air circuit control valve 10, causing air circuit control valve 10 to actuate, allowing compressed air to be injected into the tire through valve core air pipe 7. As the air pressure inside the tire increases, the outer diameter of the tire gradually increases, continuing to apply pressure to movable plate 2, and thus continuing to apply pressure to control switch 3, allowing the pressure from control switch 3 to be transmitted to pressure output terminal 9. When the pressure received by the output terminal 9 from the control switch 3 matches that of the pressure input terminal 8, the control switch 3 sends a signal to close the air circuit control valve 10, stopping the inflation of the tire 6 and preventing over-inflation that could lead to a tire explosion. An electromagnetic lock is also installed between the protective door 4 and the protective cage 1. The electromagnetic lock is connected to the air circuit control valve 10. When the air circuit control valve 10 is open to inflate the tire 6, the electromagnetic lock is locked, preventing the protective door 4 from being opened. When inflation is complete and the air circuit control valve 10 is closed, the electromagnetic lock is opened, completing the inflation operation. (The pressure comparison between the pressure input terminal 8 and the pressure output terminal 9 and the signal transmission between the air circuit control valve 10 and the control switch 3 are common knowledge to those skilled in the art. The pressure comparison method can be mechanical or electrical. The specific method used is selected by those skilled in the art based on the actual needs of the site.)
