Description

Technical Field

[0001] This utility model relates to the field of depth detection technology, specifically a tire tread depth detection device. Background Technology

[0002] Tire tread patterns increase the friction between the tire and the ground, making it easier for the vehicle to start, accelerate, and brake, reducing the skid distance on wet and slippery surfaces, improving vehicle stability during driving, and reducing sideslip.

[0003] Insufficient tire tread depth reduces the friction between the tire and the ground, making it prone to slipping on wet roads. This affects vehicle handling and braking performance, increasing the risk of traffic accidents.

[0004] Based on the measurement results of tire tread depth, car owners can reasonably arrange the time to change tires, avoiding waste or safety hazards caused by changing tires too early or too late.

[0005] The common method for measuring tire tread depth is to use a tread depth gauge. However, when measuring tire tread depth, it is necessary to rotate the tire and measure multiple tread points to ensure the accuracy of the measurement results. A common method is to suspend the tire outside the axle and measure the tire tread depth while rotating it. This method is inefficient and time-consuming. Therefore, a tire tread depth measuring device is proposed. Utility Model Content

A probe 21 is disposed at the lower end of the main gauge 23 located at the lower part of the tire tread gauge 18. A ball bearing 22 is rotatably disposed at the lower end of the probe 21.

[0034] Side block 24 is located on the outer side of tire tread gauge 18. A pull rod 25 is provided inside the side block 24 and is slidably connected to the side block 24. A disc 29 is provided at the lower end of the pull rod 25. A return spring 26 is provided between the disc 29 and the side block 24 outside the pull rod 25. A pressure plate 27 is provided at the upper end of the pull rod 25.

[0035] The display control panel 20 is located on the outer side of the shell 1.

[0036] Please see Figure 1 and Figure 2 The lower end of the pressure plate 27 is provided with a groove 28, and the groove 28 is adapted to the main scale 23. The interior of the upright shell 1 is provided with a second drive motor 13. The output end of the second drive motor 13 is equipped with a drive screw 14. The slide plate 15 is connected to the drive screw 14 by a threaded connection. The rotation of the drive screw 14 is used to control the slide plate 15 to lift and lower, so that the side plate 16 can be lifted and lowered to adapt to tires of different diameters.

[0037] Please see Figure 1 and Figure 2 The lower end of the display control screen 20 is provided with a side frame 19, which is connected to the display control screen 20 and the vertical shell 1. The side frame 19 is used to support the display control screen 20.

[0038] Please see Figure 1 and Figure 2 A grip tube 11 is provided at one end of the outer side of the clamp 10, and the grip tube 11 is connected to the clamp 10. The grip tube 11 is held so as to rotate the clamp 10.

[0041] This solution involves mounting the tire on the outside of the drive rod 7 and pressing it against the outside of the retaining shell 9. Then, by gripping the grip tube 11, the clamping shell 10 is mounted on the outside of the drive rod 7 and rotated. Through threaded engagement, the clamping shell 10 moves towards the tire, clamping and fixing it in place. The second drive motor 13 is activated, causing the drive screw 14 to rotate. With the threaded engagement and the sliding connection between the sliding plate 15 and the drive screw 14, and the sliding connection between the first sliding groove 12 and the sliding plate 15, the rotational motion of the drive screw 14 is converted into linear motion of the sliding plate 15 and the side plate 16. This causes the tire tread gauge 18 to move towards the tire, with its lower end contacting the outside of the tire. Pulling the pressure plate 27 causes the pull rod 25 to rise, and the disc 29 pushes the return spring 26 upwards. The return spring 26 is compressed and deformed under force. Then… Rotate the pressure plate 27 to the upper end of the main ruler 23, slowly release the pressure plate 27, and the return spring 26 returns to its original position, pushing the disc 29 so that the pull rod 25 drives the pressure plate 27 to move downward. The groove 28 at the lower end of the pressure plate 27 engages with the main ruler 23. The main ruler 23 moves downward, causing the probe 21 to descend and insert into the tire tread. The probe 21, in conjunction with the main ruler 23, detects the tire tread depth. The tire tread depth value is displayed on the display control screen 20. Start the first drive motor 5 to make the drive gear 6 rotate. The transmission gear 8 and the drive gear 6 mesh, which in turn causes the drive rod 7 to rotate, thereby causing the tire to rotate. The ball bearing 22 at the lower end of the probe 21 rolls inside the tire tread, thus detecting the tread depth of the rotating tire.
