When processing rubber tires, it is necessary to clamp and fix them, so a special fixing device is required.

[0003] In the Chinese utility model patent with the publication number CN216608756U, a clamping device for rubber tire detection is disclosed. This device can clamp and fix the tire by the main limit seats on the fixing component moving towards each other. In addition, auxiliary limit seats are arranged on both sides of the main limit seats, and the auxiliary limit seats can be used to cooperate with the clamping of tires with different thicknesses. Regarding the above related technology, the inventor believes that there are the following defects:

[0004] When this device is actually used, due to the elasticity of the rubber tire, the clamping and fixing method from both sides is likely to cause the tire to be deformed inward under pressure, thus affecting the detection of the tire. Therefore, we provide a rubber tire quick fixing device. Content of the Utility Model

[0005] To solve the problem that the clamping and fixing method from both sides in the above background art is likely to cause the tire to be deformed inward under pressure, thus affecting the detection of the tire, the utility model provides a rubber tire quick fixing device.

[0006] The utility model is realized by adopting the following technical solutions: A rubber tire quick fixing device includes:

[0007] A disc, one side center of the disc is fixedly connected with an electric push rod, and the telescopic end of the electric push rod penetrates through the disc and is fixedly connected with a connecting block;

[0025] Embodiment 1:

[0026] Please refer to Figures 1-3 , a rapid fixing device for rubber tires in this embodiment includes:

[0027] A disc 1, the center of one side of the disc 1 is fixedly connected with an electric push rod 2, and the telescopic end of the electric push rod 2 penetrates through the disc 1 and is fixedly connected with a connecting block 3;

[0028] A tire clamping assembly, the tire clamping assembly includes slide bars 101 fixedly connected to the disc 1 at equal intervals in the circumferential direction through brackets, an L-shaped connecting rod 102 is slidably connected to the outside of the slide bar 101, an abutting plate 103 is fixedly connected to the end of the L-shaped connecting rod 102, a link rod 104 is hinged between the L-shaped connecting rod 102 and the connecting block 3 through a hinge member, and the abutting plate 103 is designed with an arc-shaped structure, which is convenient for fitting with the tire, thereby increasing the contact area between the device and the tire, ensuring the uniformity of the force on the tire, preventing its deformation, a strip-shaped through groove for the movement of the link rod 104 is opened on one side bracket, and anti-slip particles are arranged on the surface of the abutting plate 103, which can increase the friction between the tire and the abutting plate 103, prevent slipping, and ensure the stability of the tire fixation;

[0029] A tire rotating assembly, the tire rotating assembly includes connecting frames 201 fixedly connected to the disc 1 at equal intervals in the circumferential direction, a vertical rod 202 is slidably connected to the connecting frame 201, one end of the vertical rod 202 is fixedly connected with a connecting seat, a roller 203 is rotatably connected to the connecting seat, a spring 204 is sleeved on the outside of the vertical rod 202, pin holes 205 penetrating through the vertical rod 202 are equidistantly arranged on the vertical rod 202, and a pin shaft 206 is inserted into the pin hole 205. By using the cooperation of the pin shaft 206 and the pin hole 205, the position of the roller 203 can be fixed.

[0030] In the embodiment of the present application, the implementation principle of a rapid fixing device for a rubber tire is as follows: First, place the tire between the abutting plate 103 and the roller 203. Then, start the electric push rod 2. The electric push rod 2 pushes the connecting block 3 to move. By utilizing the sliding fit between the L-shaped connecting rod 102 and the sliding rod 101, and the hinged action between the L-shaped connecting rod 102, the connecting block 3 and the connecting rod 104, the abutting plate 103 can be driven to extend outwards, so as to rapidly limit the tire from the inner side. Moreover, the multi-point support method can increase the contact area between the tire and the device, making the force on the tire more uniform. Then, pull out the pin shaft 206. By utilizing the resilience of the spring 204 and the sliding fit between the vertical rod 202 and the connecting frame 201, the roller 203 can be made to contact the surface of the tire. Subsequently, re-insert the pin shaft 206 into the pin hole 205 to limit and fix the roller 203.

When the electric push rod 2 drives the abutting plate 103 to retract, multiple groups of rollers 203 can still clamp and limit the tire. At the same time, by utilizing the rotational fit between the roller 203 and the connecting seat, the tire can be stably rotated conveniently, so as to rapidly change the processing position of the tire, further improving the practicability of the device. There is no need to repeatedly disassemble the tire, and the operation is simple, convenient and fast. Finally, just take off the processed tire.
