Abstract
Description
Technical Field
[0001] This utility model relates to the field of tire technology, and in particular to a tire pressure testing device. Background Technology
[0002] As the only component of a vehicle in contact with the ground, tires directly affect driving safety, comfort, and fuel economy. Therefore, tires must undergo rigorous testing after production to ensure compliance with national standards, industry specifications, and brand design requirements. Among these tests, pressure testing simulates extreme conditions to verify the tire's structural strength under extreme conditions, preventing tire rupture or blowouts caused by insufficient tire pressure or overload. It also verifies the tire's resistance to deformation under sudden stress, ensuring vehicle control remains intact. Therefore, tire pressure testing is a crucial step in tire research, development, production, and quality control. Currently, most existing testing equipment only tests the tire tread and cannot effectively test the tire sidewall. Although the tread provides more direct data due to its direct contact with the ground, the sidewall is thinner and more prone to rupture or blowout under sudden external forces. Therefore, sidewall testing is more necessary. Furthermore, existing testing equipment can only test each tire individually, requiring the removal and installation of another tire after each test before continuing testing. This method is time-consuming, labor-intensive, and inefficient. Utility Model Content

[0022] like Figure 1-6As shown in this embodiment, a tire pressure testing device includes a base plate 1 and a support frame set in the center of the base plate 1. The support frame includes support plates 2 arranged parallel to each other and vertically. The upper ends of the two support plates 2 are connected by a support shaft 3. A triangular rotating plate 4 is vertically arranged between the two support plates 2. The triangular rotating plate 4 is movably engaged with the support shaft 3 by a fixing sleeve 5 set in the center of its front side wall. Fixing members 6 for fixing tire hubs are respectively provided at the three corners of the triangular rotating plate 4. A driven rotating wheel 7 sleeved on the support shaft 3 is provided in the center of the rear side wall of the triangular rotating plate 4. A reduction motor 8 is provided on the rear support plate 2. The reduction motor 8 is fixed to the rear side wall of the support plate 2 by a motor bracket 9. The output shaft of the reduction motor 8 movably passes through the support plate 2 on this side and is connected to the driving rotating wheel 10. A belt 11 is wound around the driving rotating wheel 10 and the driven rotating wheel 7. A tire tread testing mechanism is provided on the base plate 1 below the triangular rotating plate 4, and a tire sidewall testing mechanism is provided on the front support plate 2.
[0023] Optionally, the fixing member 6 includes a fixing platform 601 disposed on the front side wall of the triangular rotating plate 4, a fixing seat 602 disposed on the outside of the fixing platform 601, and a plurality of studs 603 that cooperate with the wheel hub disposed on the fixing seat 602.
[0024] Optionally, the triangular rotating plate 4 is provided with clamping components that cooperate with each fixing component 6. Each clamping component includes a triangular support seat 12 fixedly sleeved on a fixing sleeve. The triangular support seat 12 is connected to the triangular rotating plate 4, and the center of each of its sides is aligned with the corner of the triangular rotating plate 4. A first guide cylinder 13 is provided on the side wall of the triangular support seat 12, and a first telescopic cylinder 14 is movably engaged within the first guide cylinder 13. The outer end of the first telescopic cylinder 14 is connected to a clamping plate 15. A first electric telescopic rod 16 is provided on the side wall of the triangular support seat 12 within the first guide cylinder 13, and the piston rod end of the first electric telescopic rod 16 is fixedly connected to the clamping plate 15. The clamping components can better secure the tire, facilitating subsequent pressure testing.
[0025] Optionally, the clamping plate 15 facing the fixing member 6 has an arc surface, and the clamping plate 15 facing the triangular rotating plate 4 has a sliding plate 17 that movably abuts against the triangular rotating plate 4. The clamping plate 15 with the arc surface can better conform to the shape of the tire, thereby increasing the contact area with the tire and improving the clamping strength with the tire.
[0026] Optionally, the tread testing mechanism includes a second guide cylinder 18 disposed on a base plate 1, a second telescopic cylinder 19 movably engaged within the second guide cylinder 18, the upper end of which is connected to an arc plate 20, a second electric telescopic rod 21 disposed on the base plate 1 within the second guide cylinder 18, the piston rod end of the second electric telescopic rod 21 being fixedly connected to the arc plate 20, a groove 22 being disposed in the center of the surface of the arc plate 20, and a first pressure detector 23 being disposed within the groove 22.

[0028] Before using this device, each tire needs to be installed on the respective fixing member 6, so that the tires mounted on the rims are locked onto the studs 603 of the fixing base 602, thus fixing their positions. Then, the corresponding tires on the corresponding sides are clamped with clamping members. The first electric telescopic rod 16 pushes the clamping plate 15 outward, and the clamping plate 15 moves outward along the first guide cylinder 13 through the first telescopic cylinder 14 to ensure smooth movement until the clamping plate 15 abuts against the tire surface, facilitating subsequent pressure testing. During use, the reduction motor 8 is started. The output shaft of the reduction motor 8 drives the driving wheel 10 to rotate, which in turn drives the driven wheel 7 to rotate through the belt 11. As the driven wheel 7 rotates, it drives the triangular rotating plate 4 to rotate radially along the direction of the fixing sleeve 5 until one of the fixing members 6 for mounting the tire is located between the two support plates 2. Then, the second electric telescopic rod 21 is activated. The piston rod of the second electric telescopic rod 21 drives the arc plate 20 to move upward. The arc plate 20 then moves vertically upward along the second guide cylinder 18 through the second telescopic cylinder 19 until the first pressure detector 23 contacts the tire tread and performs a pressure test. When performing a sidewall test, the drive cylinder 24 operates. The piston rod of the cylinder 24 drives the second pressure detector 25 to move outward until it contacts the tire sidewall and performs a pressure test. Its structure is reasonably designed and easy to operate. It can not only complete the test of the tire tread but also effectively test the tire sidewall, thereby obtaining more accurate tire data. This provides effective data support for tire research and development, production, and quality control. Simultaneously, multiple tires can be tested continuously, and the disassembly and installation of other tires can be completed during the testing process, saving time and labor, greatly improving testing efficiency, and solving the problems existing in the prior art.
