By changing the inflation amount of the tire 0, the pressure resistance of the tire 0 under different air pressures can be detected. By using the adjustment mechanism 4 of the device, the detection condition of the tire 0 can be adjusted. When the tire 0 moves downward and contacts the first connecting roller 311 on the connecting plate 2, the second motor 40 can be started to drive the first screw rod 41 to rotate, so that the first moving frame 42 drives the connecting column 20 to move leftward, so that the connecting plate 2 moves leftward, and the contact area between the tire 0 and the first connecting roller 311 is adjusted to simulate the driving condition of the tire 0 on an uneven road surface.

5. A tire pressure resistance detection device according to claim 3, characterized in that: The second connecting rollers (49) are all provided with convex points.

6. A tire pressure resistance detection device according to claim 3, characterized in that: The invention also comprises a water spray mechanism (5), which comprises a connecting and fixing support frame (50), a connecting pipe (51) and a spray head (52). The upper right part of the base (1) is connected to the connecting and fixing support frame (50), the connecting pipe (51) is connected to the connecting and fixing support frame (50), and the lower side of the connecting pipe (51) is connected to a plurality of spray heads (52). When the tire (0) is inspected, water is passed into the connecting pipe (51), so that the spray head (52) sprays water onto the tire (0).

7. A tire pressure resistance detection device according to claim 6, characterized in that: The nozzles (52) are all trumpet-shaped.

8. A tire pressure resistance detection device according to claim 6, characterized in that: The invention also comprises a marking mechanism (6), which comprises a fixed bracket (60), a third cylinder (61) and a marking pen (62). The fixed bracket (60) is connected to the right side of the middle of the base (1), the third cylinder (61) is connected to the fixed bracket (60), the telescopic end of the third cylinder (61) passes through the base (1), and the left side of the telescopic end of the third cylinder (61) is connected to the marking pen (62). After the tire (0) is placed downward on the connecting plate (2), the third cylinder (61) is started to move the marking pen (62) to contact the tire (0).

9. A tire pressure resistance detection device according to claim 8, characterized in that: The device also comprises a placement mechanism (7), which comprises a connecting and fixing frame (70) and a placement rod (71). The left side of the base (1) is connected to the connecting and fixing frame (70), and the upper part of the connecting and fixing frame (70) is connected to the placement rod (71). When testing, the tires (0) to be tested are hung one by one on the placement rod (71), and when testing is required, the tires (0) are removed from the placement rod (71).

10. A tire pressure resistance detection device according to claim 9, characterized in that: The utility model also comprises a prompting mechanism (8), which comprises a fixed column (80), a guide knocking column (81), a second spring (82) and a prompting bell (83). The fixed column (80) is connected to the rear side of the connecting column (20), the guide knocking column (81) is slidably connected to the fixed column (80), the second spring (82) is connected between the guide knocking column (81) and the fixed column (80), and the prompting bell (83) is connected to the rear side of the lower part of the first movable frame (42) at the rear side. When the connecting column (20) rotates, the fixed column (80) and the guide knocking column (81) are driven to rotate, so that the guide knocking column (81) hits the prompting bell (83) under the action of the second spring (82), so that the prompting bell (83) rings.
