[0024] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0025] like Figures 1-5 As shown, the tire inner support special quick disassembly and assembly tool includes a box body 1. The inner side of the box body 1 is fixedly connected to the fixed end of the cylinder 3. The telescopic end of the cylinder 3 passes through the sleeve hole 7 and is fixedly connected to the clamping plate 6. The sleeve hole 7 is opened on the right side of the box body 1. The bottom of the box body 1 is provided with a fixing mechanism 5.

[0026] Furthermore, the cylinder 3 is connected to the pneumatic switch 8 via two air supply pipes 2, and the pneumatic switch 8 is fixedly connected to the front end of the threaded seat 9 via multiple bolts 14.

[0027] Furthermore, the rear end of the threaded seat 9 is fixedly connected to the inner rear side of the housing 1, and the pneumatic switch 8 is also fixedly connected to one end of the air inlet pipe 10. When using this device, the air inlet pipe 10 can be connected to an external air source first, and then the position of the card plate 6 can be adjusted by controlling the extension and retraction of the cylinder 3 using the pneumatic switch 8.

[0028] Furthermore, the other end of the intake pipe 10 passes through the sleeve hole 12 and extends to the outside of the housing 1, with the sleeve hole 12 being opened on the upper surface of the housing 1.

[0029] Furthermore, the fixing mechanism 5 includes a fixing plate 51, which is fitted inside the groove 4, and the groove 4 is opened on the bottom surface of the box body 1.

[0030] Furthermore, the middle part of the fixing plate 51 is fixedly connected to the bottom end of the rotating shaft 56, and the rotating shaft 56 is fixedly connected to the bottom surface of the housing 1 through a sealed bearing.

[0031] Furthermore, the upper end of the rotating shaft 56 extends into the housing 1 and is fixedly provided with a worm gear 52. The worm gear 52 is meshed with the worm 53. By setting the rotating shaft 56 to be connected to the fixed plate 51, and setting the worm gear 52 and the worm 53 to be connected to the rotating shaft 56, when using this device, the worm 53 and the worm gear 52 can be used to control the rotation of the rotating shaft 56 and the fixed plate 51 to adjust the position of the clamping plate 55, so that the gap between the clamping plate 55 and the hub spokes corresponds, so that the clamping plate 55 can pass through the gap of the spokes and enter the interior of the hub.

[0032] Furthermore, the optical shaft at the rear end of the worm gear 53 is rotatably connected to the rear side of the housing 1 via a bearing. A wheel is fixedly installed at the front end of the worm gear 53. Screw holes 57 are opened at both ends of the fixing plate 51. The two screw holes 57 are threadedly connected to the two screws 54 respectively. After the clamping plate 55 is placed inside the hub through the gap of the spoke plate, the user can pull the clamping plate 55 to rotate so that the opposite ends of the two clamping plates 55 are rotated to the lower part of the center of the hub. And rotate the screw 54 so that the screw 54 moves upward along the screw hole 57 and drives the clamping plate 55 to move upward. When the clamping plate 55 is in close contact with the inner side of the center of the hub, stop rotating the screw 54 to complete the fixation of the device, thereby fixing the position of the housing 1 so as to use the movement of the clamping plate 6 to push the tire beak to expand.

[0033] Furthermore, the bottom optical shafts of the two screws 54 are rotatably connected to the opposite ends of the two clamping plates 55 via bearings. A wheel is fixedly installed at the upper end of each of the two screws 54, and a through groove 13 is correspondingly provided above each of the two screws 54. The two through grooves 13 are opened at the upper end of the groove 4 and are connected to the lower inner side and rear side of the housing 1. By providing a through groove 13 at the bottom of the housing 1 corresponding to the screws 54, when the rotating shaft 56 drives the fixing plate 51 and the screws 54 to rotate, the screws 54 can pass through the through groove 13, thereby achieving the purpose of adjusting the position of the clamping plate 55.

[0034] Furthermore, a handle 11 is fixedly installed on the upper surface of the box 1, and the card plate 6 is U-shaped.

[0035] The working principle of the utility model is: when the device is used to assist maintenance personnel to dismount the inner support of the tire, the user can first adjust the position of the clamping plate 55 according to the hub spoke position, at this time the user can rotate the worm 53 to drive the rotating shaft 56, the fixed plate 51 and the clamping plate 55 to rotate by the worm wheel 52, so that the clamping plate 55 is rotated to correspond to the gap between the two spokes, the bottom end of the clamping plate 6 can be placed at the toe of the tire, and the box body 1 is placed on the outer side of the tire hub, then the user can pull the clamping plate 55 to rotate so that the opposite ends of the two clamping plates 55 are rotated to below the hub center part, and the screw rod 54 is rotated so that the screw rod 54 moves upwards along the screw hole 57 to drive the clamping plate 55 to move upwards, when the clamping plate 55 is in close contact with the inner side of the hub center, the rotation of the screw rod 54 is stopped to complete the fixation of the device;

[0036] Then the user can connect the air inlet pipe 10 with the air source outside, and control the air cylinder 3 to extend to push the clamping plate 6 to move outside the box body 1 by the pneumatic switch 8, so that the clamping plate 6 clamps the toe of the tire to move outward, the space between the tire and the hub is increased, the clamping plate 6 is stopped to extend when the clamping plate 6 moves to the appropriate position, at this time the inner support of the tire can be dismounted through the gap between the tire and the hub, after the maintenance work is completed, the air cylinder 3 can be controlled to shrink to restore the clamping plate 6 to the original position, then the screw rod 54 is reversely rotated to make the clamping plate 55 separate from the inner side of the hub, and the clamping plate 55 is rotated to correspond to the gap between the spokes, at this time the box body 1 can be pulled upwards to take off the box body 1 from the hub.

[0037] The above is only the preferred embodiment of the utility model, it should be pointed out that, for ordinary skilled person in the art, without departing from the principle of the utility model, a number of improvements and refinements can be made, these improvements and refinements should also be regarded as the protection scope of the utility model. The structures, devices and operation methods not specifically described and explained in the utility model are implemented according to the conventional means in the art, without special description and limitation.
