[0026] As shown in the drawings, a tire tread measuring device comprises a box 1, a transparent plate 2 is arranged on the top of the box 1 for placing a tire tread; further comprising: Figures 1-4

[0027] a transmission assembly 3, the transmission assembly 3 comprises a driving sprocket 31, a driven sprocket 32 and a chain 33 connecting the two, the driven sprocket 32 is fixedly installed at the bottom end of a transmission screw 34;

[0028] a lifting assembly 4, the lifting assembly 4 comprises a lifting plate 41 which is threadedly connected with the transmission screw 34, the transmission screw 34 is vertically arranged in the box 1;

[0029] a detector 5, the detector 5 is arranged on the lifting plate 41.

[0030] ​Specifically, the box 1 is used as a basic bearing structure, and a transparent plate 2 is mounted on the top of the box 1 for placing the tire tread. The transparent plate 2 is made of tempered glass or acrylic material and is fixed on the top of the box 1 by bolts. The driving sprocket 31 and the driven sprocket 32 are connected by the chain 33 to form a transmission link, and the driven sprocket 32 is fixedly installed at the bottom end of the transmission screw 34 to realize power transmission. The driving sprocket 31 can be manually driven or motor driven. In this embodiment, a manual crank is arranged on the driving sprocket 31, and the driving sprocket 31 is manually rotated. The lifting plate 41 of the lifting assembly 4 is threadedly connected with the transmission screw 34, and the transmission screw 34 is stably installed in the box 1 by bearings. The detector 5 is arranged on the lifting plate 41 and moves with the lifting plate 41. When the device is running, the driving sprocket 31 rotates, and the chain 33 drives the driven sprocket 32 to rotate synchronously. Since the driven sprocket 32 is fixedly connected with the transmission screw 34, the transmission screw 34 starts to rotate. The transmission screw 34 stably rotates under the support of the bearings and drives the lifting plate 41 to move up and down along the axial direction of the transmission screw 34 through the thread connection with the lifting plate 41. The detector 5 installed on the lifting plate 41 also moves vertically. By adjusting the height of the lifting plate 41, the distance between the detector 5 and the tire tread is changed. In this application, the transmission assembly 3 is arranged to adopt the chain and sprocket connection mode, which is simple and efficient. The transmission screw 34 provides stable support for the lifting of the lifting plate 41. The lifting assembly 4 and the transmission assembly 3 ensure that the lifting action is accurately controllable, meet the requirements of measuring different height positions of the tire tread, and can be flexibly adjusted in height to meet the diversified measurement requirements of different specifications of tire tread, greatly improving the practicality of the device, adapting to the observation requirements of different details of the tire tread, and realizing more accurate measurement.

[0031] As shown in Figure 1 , 2 , the transmission screw 34 is two, symmetrically distributed on both sides of the box 1, and each transmission screw 34 is fixed with a driven sprocket 32 at the bottom end. The driving sprocket 31 drives two driven sprockets 32 through the chain 33.

[0032] Specifically, the chain 33 forms a triangular closed loop path around the driving sprocket 31 and the two driven sprockets 32, and the rotation of the driving sprocket 31 drives the two driven sprockets 32 to rotate synchronously through the chain 33. Since the driven sprockets 32 are fixed at the bottom ends of the two transmission screws 34, the two transmission screws 34 rotate synchronously and in the same direction. The two transmission screws 34 are symmetrically distributed and work synchronously, ensuring the stability and synchronization of the lifting plate 41 during lifting, making the lifting plate 41 move vertically without deviation, and accurately controlling the height position of the detector 5 to meet the high-precision measurement requirements.

[0033] As shown in Figure 1As shown, the lifting assembly 4 includes two lifting plates 41 respectively arranged on the transmission screw rods 34, and a connecting bracket 42 is arranged between the two lifting plates 41, and the detector 5 is arranged on the connecting bracket 42.

[0034] Specifically, the two lifting plates 41 are respectively arranged on the two transmission screw rods 34, which can provide more balanced and stable support for the connecting bracket 42 from both sides. The two transmission screw rods 34 rotate synchronously, driving the two lifting plates 41 to rise and fall synchronously, and the connecting bracket 42 is more evenly stressed in this process and is not prone to tilting or shaking, ensuring the stability of the detector 5 installed on the connecting bracket 42 during vertical movement.

[0035] As shown in Figure 1 , 3 , the lifting assembly 4 further includes a guide rod 43, which is arranged in parallel with the transmission screw rod 34 and is in sliding connection with the lifting plate 41 to limit the circumferential deviation thereof.

[0036] Specifically, the guide rod 43 is arranged in parallel with the transmission screw rod 34 and is in sliding connection with the lifting plate 41, which can provide reliable guiding effect for the lifting plate 41. When the transmission screw rod 34 drives the lifting plate 41 to move up and down, the guide rod 43 can limit the deviation of the lifting plate 41 in the radial direction, so that it can only move smoothly in the vertical direction, thereby ensuring the position accuracy of the detector 5 during measurement and improving the accuracy of measurement.

[0037] As shown in Figure 1 , 2 , the detector 5 is in sliding connection with the connecting bracket 42 and can slide horizontally and be fixed by a locking knob.

[0038] Specifically, the detector 5 can slide horizontally on the connecting bracket 42, so that it can flexibly adjust the position according to the measurement needs of different tire treads. For tire treads of different widths or shapes, the detector 5 can be slid to the optimal measurement position to ensure that the required parameters can be accurately measured, thereby improving the adaptability of the equipment to various types of tire treads.

[0039] As shown in Figure 1 , the detector 5 is a laser measuring instrument or an industrial camera, and the detector 5 is connected with the computer 6 and transmits detection data to the computer 6.

[0040] Specifically, in the tire tread measuring device, the detector 5 has a variety of choices, which can be a laser measuring instrument or an industrial camera, greatly expanding the detection capability of the device. The laser measuring instrument can accurately measure the size parameters of the tire tread, such as the pattern depth, etc. When the detector 5 is an industrial camera, the industrial camera shoots a high-definition image of the tire tread, and uses image processing algorithms to identify and analyze whether there are surface defects such as cracks and bubbles in the image. The detector 5 is connected to the computer 6, realizing efficient transmission of detection data. Whether the data collected by the laser measuring instrument or the industrial camera can be transmitted to the computer 6 in time. The computer 6 can further analyze, store and display these data by virtue of its powerful data processing capability.
