Description

Technical Field

[0001] This utility model belongs to the field of tire technology, specifically relating to a tire rear air inflation device. Background Technology

[0002] Tire manufacturers often use a burst inflation method when inflating tires. Burst inflation is a rapid inflation technology that uses a burst inflator with an automatic lifting function to inject a large amount of high-pressure gas into the tire in a short time, so that the tire can quickly reach the required pressure value.

[0003] However, when a tire is overinflated, the internal air pressure rises sharply. If the tire is not stable enough, it is easy for it to move unexpectedly. This unexpected movement may not only damage the tire, but also cause harm to the operator and the surrounding environment.

[0004] Therefore, in order to address the aforementioned technical problems, it is necessary to provide a tire rear air inflator.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

Detailed Implementation

[0027] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0028] like Figures 1-2 and Figures 5-6As shown, a tire rear-mounted air-inflating device according to one embodiment of this utility model includes a lifting controller 1, an air-inflator 2 installed below the lifting controller 1, a support assembly 3 installed below the air-inflator 2, a power assembly 4 fixedly connected to the inner wall of the support assembly 3, and a tire located on the top end face of the power assembly 4 and directly below the air-inflator 2. A protective assembly 5 matching the support assembly 3 is installed on the outer wall of the power assembly 4 and located below the tire. During use, when the air-inflator 2 moves downward, it exerts a downward force on the tire, causing the tire to move the power assembly 4 downward, which in turn causes the power assembly 4 to move the protective assemblies 5 on both sides upward. During tire inflation, the protective assemblies 5 are positioned on the outer rim of the tire, preventing tire displacement and potential harm to personnel and the environment, and ensuring inflation efficiency.

[0029] like Figures 3-4 As shown, the support assembly 3 includes an air-filling platform 301, and an integrally formed basin-type support seat 302 on the inner wall of the air-filling platform 301. The power assembly 4 includes a support plate 401, the outer wall of the support plate 401 is attached to the top inner wall of the basin-type support seat 302, a pair of first sliding grooves 3021 are formed on the inner wall of the basin-type support seat 302, and a pair of first sliders 4012 that match the pair of first sliding grooves 3021 are integrally formed on the bottom outer wall of the support plate 401. The outer wall of the first sliders 4012 is slidably connected to the inner wall of the first sliding grooves 3021. When the tire exerts a downward force, the outer wall of the support plate 401 slides downward on the inner wall of the basin-type support seat 302. At this time, the first sliders 4012 located on opposite sides of the support plate 401 slide on the inner wall of the first sliding grooves 3021, thereby increasing the stability of the support plate 401 when sliding downward.

[0030] like Figures 3-6 As shown, a pair of brackets 404 are fixedly connected to the inner wall of the bottom end of the basin-type support 302 on both sides of the through groove 304. A rotating groove is provided on the inner wall of each pair of brackets 404. A pressure column 4011 is fixedly connected to the bottom end face of the support plate 401. A rotating column 4031 is rotatably connected to the inner wall of the rotating groove. A rocker arm 403 is integrally formed on the outer wall of the rotating column 4031. A pressure block 4032 is welded to one end of the rocker arm 403. The top end face of the pressure block 4032 is attached to the bottom end face of the pressure column 4011. A pair of first openings are provided on the inner wall of the basin-type support 302. The first opening groove 3022 has a through groove 3022. The end of the rocker arm 403 away from the pressure block 4032 passes through and slides on the inner wall of the first opening groove 3022. The bottom end face of the air-filling platform 301 has a through groove 304. When the support plate 401 moves downward, it drives the pressure column 4011 to move downward, thereby driving the pressure block 4032 located at one end of the rocker arm 403 to move downward. At this time, the two ends of the rotating column 4031 rotate in the rotating groove of the bracket 404, thereby driving the other end of the rocker arm 403 to move upward, so that one end of the rocker arm 403 passes through and slides on the inner wall of the first opening groove 3022.

[0031] Furthermore, the protective component 5 includes a protective plate 501. The outer wall of the protective plate 501 has a through hole 5011 that matches the rocker arm 403. One end of the rocker arm 403 passes through and slides against the inner wall of the through hole 5011. Two pairs of T-shaped grooves 3023 are formed on the outer wall of the basin-type support 302. A T-shaped slider 502 matching the T-shaped grooves 3023 is integrally formed on the inner wall of the protective plate 501. An arc-shaped groove 303 matching the protective component 5 is formed on the end face of the air-filling platform 301. The outer wall of the protective plate 501... The wall slides on the inner wall of the arc groove 303, and the outer wall of the T-shaped slider 502 slides on the inner wall of the T-shaped groove 3023. When one end of the rotating column 4031 moves upward, one end of the rocker arm 403 is located in the through hole 5011, thereby driving the protective plate 501 to slide upward through the arc groove 303. At the same time, the T-shaped slider 502 slides on the inner wall of the T-shaped groove 3023, thereby realizing that the deflation inflator 2 presses down on the tire while the protective component 5 rises, which plays a certain limiting role on the tire and prevents it from displacing.

[0032] Furthermore, multiple sets of dampers 405 are installed on the bottom end face of the support plate 401. The bottom end of the damper 405 is installed on the inner wall of the bottom end of the basin support 302. A spring 406 is sleeved on the outside of the damper 405. After the tire is fully inflated, the lifting controller 1 drives the deflation pump 2 to move upward, so that the deflation pump 2 is away from the top of the tire. At this time, the tire and the support plate 401 move upward under the action of the damper 405 and the spring 406. At the same time, the rocker arm 403 returns to the initial state. The protective component 5 moves downward under the action of the rocker arm 403 until it does not protrude from the top end face of the inflation platform 301. Then, the workers can transport the tire to other processes.

[0033] When using it, in the initial state, such as Figure 1 and Figure 5 As shown, the tire is placed above the support plate 401, at which point the protective component 5 does not protrude from the top end face of the air-filling platform 301; in the working state, as... Figure 2 and Figure 6 As shown, the lifting controller 1 is activated, causing it to slowly move the inflator 2 downwards. Then, the bottom of the inflator 2 moves downwards, touching the top of the tire. This causes the tire to exert a downward force on the pressure column 4011, moving one end of the rocker arm 403 (the pressure block 4032) downwards. Simultaneously, the end of the rocker arm 403 away from the pressure column 4011 moves upwards, thereby moving the protective plate 501 upwards. At this point, the tire is located inside the protective plate 501, thus preventing tire displacement during inflation. When the work is completed, as shown... Figure 1 and Figure 5As shown, after the inflation work is completed, the lifting controller 1 drives the air inflator 2 to rise slowly, so that the bottom end face of the air inflator 2 is away from the top of the tire. Then, under the action of the damper 405 and the spring 406, the support plate 401 moves upward, thereby driving the tire to move upward. At this time, the pressure block 4032 located below the pressure column 4011 on the rocker arm 403 moves upward, and the other end of the rocker arm 403 drives the protective component 5 to move downward, so that when the protective component 5 returns to the initial state, it does not protrude from the top end face of the inflation platform 301, which facilitates the subsequent transportation work.
