Description

Technical Field

[0001] This application relates to the field of tire repair technology, specifically a tire repair pressing mechanism. Background Technology

[0002] Tires are circular, elastic rubber products that are mounted on various vehicles or machinery and roll on the ground. They are typically mounted on metal rims, supporting the vehicle body, cushioning external impacts, ensuring contact with the road surface, and guaranteeing the vehicle's driving performance. When a tire is damaged, it can be retreaded to restore its functionality, replacing worn or otherwise damaged tires. This process requires a pressing mechanism to increase the tightness between the patch and the tire.

[0003] Patent CN205997391U discloses a tire repair and pressing mechanism. This mechanism suspends the tire on a cam, with a lower pressing frame rotated to a position directly below the upper pressing frame. Rotating the handle, via a screw drive, moves the lower pressing frame downwards until the cam and concave wheel press the tire to a certain extent. A first motor then drives the concave wheel to rotate, achieving tire repair and pressing. This device is simple in structure, convenient to use, and low in cost. However, the fixed cam position and height of this pressing mechanism increase friction between the tire bottom and the ground during pressing, leading to increased tire damage and shortened tire lifespan after repair. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this application provides a tire repair and pressing mechanism that solves the problems mentioned in the background section.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this application provides the following technical solution: a tire repair pressing mechanism, comprising a base plate, an adjustment mechanism for adjusting the pressing distance, and a pressing mechanism for tightly connecting the patch and the original tire. A lifting mechanism for adjusting the tire height during pressing is connected to the top left side of the base plate. The lifting mechanism includes a screw and a moving ring. The screw is positioned above the base plate, and the inner wall of the moving ring is threadedly connected to the surface of the screw. The left side of the adjustment mechanism is connected to the right side of the lifting mechanism, and the pressing mechanism is connected to the adjustment mechanism.

[0008] By adopting the above technical solution, the screw rotation can drive the moving ring to move up and down, thereby moving the pressed tire to a suitable height and avoiding tire friction damage.

[0009] Preferably, the lifting mechanism further includes a side plate and a first motor. The bottom of the side plate is connected to the top left side of the base plate. A movable groove is provided on the left side of the side plate. The bottom of the inner wall of the movable groove is rotatably connected to the bottom of the screw. The first motor is connected to the top of the side plate, and the output shaft of the first motor is connected to the top of the screw.

[0010] By adopting the above technical solution, the output shaft of the first motor at the top of the side plate can be used to drive the screw in the movable slot to rotate, providing power support for the operation of the lifting mechanism.

[0011] Preferably, the lifting mechanism further includes a limiting plate and a sliding groove. The limiting plate is connected to one side of the moving ring, and the sliding groove is opened on both sides of the movable groove. The sliding groove is slidably connected to the limiting plate.

[0012] By adopting the above technical solution, the sliding connection between the limiting plate and the slide groove can be used to convert the rotation of the moving ring driven by the screw into the up and down movement of the moving ring, thereby improving the stability of the moving ring when it moves upward.

[0013] Preferably, the lifting mechanism further includes a connecting rod, which is connected to the right side of the moving ring.

[0014] By adopting the above technical solution, the lifting mechanism and the adjusting mechanism can be connected by a connecting rod, and the tire can be provided with support force during pressing.

[0015] Preferably, the adjustment mechanism includes a U-shaped frame and a fixed plate. The left side of the U-shaped frame is connected to one end of the connecting rod, the left side of the fixed plate is connected to the lower right side of the U-shaped frame, a fixed block is connected to the top of the fixed plate, and a bidirectional hydraulic rod is connected to the fixed block.

[0016] By adopting the above technical solution, the bidirectional hydraulic rod connected to the top fixing block of the fixed plate connected by the U-shaped frame can provide power support for adjusting the pressing gap, thus ensuring the accuracy of the pressing gap.

[0017] Preferably, the adjustment mechanism further includes a fixed ring and a support plate. The side of the fixed ring is connected to one end of a bidirectional hydraulic rod, and a folding frame is rotatably connected to the inner wall of the fixed ring. The bottom of the support plate is slidably connected to the top of the folding frame.

[0018] By adopting the above technical solution, the bidirectional hydraulic rod can be extended to drive the fixed ring to move in opposite directions. The movement of the fixed ring in opposite directions causes the folding frame to extend, and the extension of the folding frame causes the support plate to move up to a suitable height, thus ensuring the pressing effect.

[0019] Preferably, the pressing mechanism includes a retaining plate and a concave wheel. The top of the retaining plate is connected to one side of the top of the inner wall of the U-shaped frame. A second motor is connected to one side of the retaining plate, and one side of the concave wheel is connected to the output shaft of the second motor.

[0020] By adopting the above technical solution, the output shaft of the second motor connected to the fixing plate can be rotated to drive the concave wheel to rotate, which is convenient for moving and pressing tires of different sizes, thus expanding the range of tire repair.

[0021] Preferably, the pressing mechanism further includes a support column and a rotating ball, the bottom of the support column is connected to the top of the support plate, the top of the support column has a rotating groove, and the surface of the rotating ball is rotatably connected to the inner wall of the rotating groove.

[0022] By adopting the above technical solution, the rotation of the ball bearing in the groove opened at the top of the support column can be used to facilitate the movement of the pressed tire position, thereby making the tire repair area more evenly stressed and improving the tightness between the repair patch and the tire.

[0023] (III) Beneficial Effects

[0024] This application provides a tire repair and pressing mechanism, which has the following beneficial effects:

[0025] 1. This tire repair pressing mechanism, by setting up a lifting mechanism, the output shaft of the first motor at the top of the side plate rotates, driving the screw connected to the movable groove to rotate. The rotation of the screw drives the moving ring connected to the limiting plate in the slide groove to move upward. The upward movement of the moving ring drives the connecting rod to move upward to a suitable height, avoiding the possibility of tire damage caused by the friction between the bottom of the tire and the ground when the tire is pressed and moved, ensuring the integrity of other parts during tire repair, and extending the service life of the repaired tire;

[0026] 2. This tire repair pressing mechanism, through the setting of an adjustment mechanism, shortens the bidirectional hydraulic rod connected to the fixed block at the top of the fixed plate connected to the U-shaped frame, causing the fixed ring to move towards each other. The movement of the fixed ring towards each other causes the folding frame to extend. The extension of the folding frame causes the support plate to move up to a suitable height, reducing the difficulty of adjusting the pressing gap, improving the accuracy of the pressing gap value, ensuring the pressing effect, and improving the tire repair efficiency.

For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0036] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0037] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4This application provides a tire repair pressing mechanism, including a base plate 1, an adjusting mechanism 3 for adjusting the pressing distance, and a pressing mechanism 4 for tightly connecting the patch and the original tire. A lifting mechanism 2 for adjusting the tire height during pressing is connected to the top left side of the base plate 1. The lifting mechanism 2 includes a screw 204 and a moving ring 205. The screw 204 is positioned above the base plate 1, and the inner wall of the moving ring 205 is threadedly connected to the surface of the screw 204. A side plate 201 is connected to the top left side of the base plate 1. A movable groove 202 is formed on the left side of the side plate 201, and the bottom of the inner wall of the movable groove 202 is rotatably connected to the bottom of the screw 204. A first motor 203 is connected to the top of the side plate 201, and the output shaft of the first motor 203 is connected to the screw 204. 4. The top connection is provided. A limiting plate 206 is connected to one side of the moving ring 205. Slide grooves 207 are provided on both the front and rear sides of the movable groove 202. The slide grooves 207 are slidably connected to the limiting plate 206. A connecting rod 208 is connected to the right side of the moving ring 205. The left side of the adjusting mechanism 3 is connected to the right side of the lifting mechanism 2. The pressing mechanism 4 is connected to the adjusting mechanism 3. The output shaft of the first motor 203 at the top of the side plate 201 rotates, which drives the screw 204, which is rotatably connected to the movable groove 202, to rotate. The rotation of the screw 204 drives the moving ring 205, which is connected to the limiting plate 206 in the slide groove 207, to move upward. The upward movement of the moving ring 205 drives the connecting rod 208 to move upward. The upward movement of the connecting rod 208 drives the tire at the top of the ball bearing 406 to move to a suitable height.

[0038] Reference Figure 5 and Figure 6 In one aspect of this embodiment, the adjustment mechanism 3 includes a U-shaped frame 301 and a fixing plate 302. The left side of the U-shaped frame 301 is connected to one end of the connecting rod 208, and the left side of the fixing plate 302 is connected to the lower right side of the U-shaped frame 301.

A folding frame 306 is rotatably connected to the inner wall of the fixing ring 305, and a support plate 307 is slidably connected to the top of the folding frame 306. When the bidirectional hydraulic rod 304 connected to the fixing block 303 at the top of the fixing plate 302 connected to the U-shaped frame 301 shortens, it causes the fixing ring 305 to move towards each other. When the fixing ring 305 moves towards each other, it causes the folding frame 306 to extend. When the folding frame 306 extends, it causes the support plate 307 to move upward, causing the top of the tire repair area to fit against the concave wheel 403.

[0039] Reference Figure 5 and Figure 6In one aspect of this embodiment, the pressing mechanism 4 includes a retaining plate 401 and a concave wheel 403. The top of the retaining plate 401 is connected to one side of the top of the inner wall of the U-shaped frame 301. A second motor 402 is connected to one side of the retaining plate 401. One side of the concave wheel 403 is connected to the output shaft of the second motor 402. A support column 404 is connected to the top of the support plate 307. A rotating groove 405 is opened on the top of the support column 404. A rotating ball 406 is rotatably connected to the inner wall of the rotating groove 405. The output shaft of the second motor 402 on one side of the retaining plate 401 rotates to drive the concave wheel 403 to rotate. The rotation of the concave wheel 403 drives the rotating ball 406 in the rotating groove 405 of the support column 404 to rotate, thereby pressing the repair area.

[0040] All electrical devices in this plan are powered by an external power source.

[0041] Working principle: In use, the tire is placed on top of the rotating ball 406. The output shaft of the first motor 203 at the top of the side plate 201 rotates, driving the screw 204, which is rotatably connected to the movable groove 202, to rotate. The rotation of the screw 204 causes the moving ring 205, which is connected to the limiting plate 206 in the slide groove 207, to move upward. The upward movement of the moving ring 205 causes the connecting rod 208 to move upward. The upward movement of the connecting rod 208 causes the tire on top of the rotating ball 406 to move to the bottom and lift off the ground. The fixed plate 302, which is connected to the U-shaped frame 301, then... The bidirectional hydraulic rod 304 connected to the top fixing block 303 shortens, causing the fixing ring 305 to move towards each other. The movement of the fixing ring 305 towards each other causes the folding frame 306 to extend. The extension of the folding frame 306 causes the support plate 307 to move upward, causing the top of the tire repair area to fit against the concave wheel 403. The output shaft of the second motor 402 on one side of the fixing plate 401 rotates, causing the concave wheel 403 to rotate. The rotation of the concave wheel 403 causes the rotating ball 406 in the rotating groove 405 of the support column 404 to rotate, pressing the repair area together.
