[0029] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0030] Please see Figures 1 to 6 This utility model provides a tire pressing device, including a base 100, a workbench 200, a clamp 300, a lifting rod 400, and a pressing block 500.

[0031] The workbench 200 is rotatably arranged at the top end of the base 100, and the workbench 200 is provided with a positioning hole, and the end of the tower base 1 of the wheel can be inserted into the positioning hole. It should be noted that in the specific implementation, a soft pad ring matched with the outer diameter of the tower base 1 can be arranged in the positioning hole, so as to improve the stability between the tower base 1 and the positioning hole, and at the same time, the outer wall of the tower base 1 is protected.

[0032] The clamp 300 comprises a plurality of limiting blocks 310. The plurality of limiting blocks 310 are arranged on the workbench 200 in a circumferential direction and are centered on the positioning hole. When the rim 2 is installed on the workbench 200, the clamp 300 can abut against the lower edge of the outer wall of the rim 2. The hanger rod 400 is arranged on the base 100 through a cantilever support and extends towards the ground, and the hanger rod 400 can move in the radial direction of the positioning hole.

[0033] The pressing block 500 is installed at the bottom end of the hanger rod 400, and the front and rear ends of the pressing block 500 are spaced apart to form a guide portion 510 and a guide portion 520. The lower end surface of the guide portion 510 is flush with the upper surface of the rim 2, and the lower surface of the guide portion 520 is flush with the upper outer ring of the rim groove of the rim 2.

[0034] In use, after the tower base 1, the hub, the rim 2 and the spokes are assembled, the end of the tower base 1 is inserted into the positioning hole, and all the clamps 300 abut against the lower edge of the rim 2. Then, the tire is placed on the rim 2, and the air valve on the tire is inserted through the corresponding perforation of the rim 2. Then, the hanger rod 400 is moved until the lower end surface of the guide portion 510 is flush with the upper surface of the rim 2, and the lower surface of the guide portion 520 is flush with the upper outer ring of the rim groove of the rim 2. Then, the tire is manually pressed down so that part of the tire is below the guide portion 510 and the guide portion 520. Then, the rim 2 is rotated towards the guide portion 520. During the rotation, the guide portion 510 presses down the edge of the tire. As the tire continues to rotate, the pressed part is guided into the rim groove under the action of the guide portion 520. As the rim 2 continues to rotate, the entire tire is completely fitted into the rim groove. Then, the hanger rod 400 is moved radially away, and the entire tire is removed, completing the assembly of the tire.

[0035] The tire pressing device can position the tire through the clamps, and the guide portion and the guide portion can guide during the pressing process, so that the tire can be quickly installed in the rim groove, and the entire device has a simple structure and is easy to operate.

[0036] In this embodiment, the cantilever support is provided with a first sliding groove which is downwardly open and extends in the radial direction of the positioning hole, and the top of the hanger rod 400 is provided with a first sliding block 410 which is slidably arranged in the first sliding groove.

[0037] In use, the press-fit block 500 can be moved to the desired position by pulling the lifting rod 400 along the first sliding groove.

[0038] As a preferred embodiment, the top surface of the first sliding groove is provided with a plurality of grooves at intervals along the length direction thereof, and the bottom surface of the first sliding block 410 is provided with a plurality of protrusions. The first elastic member 420 is connected between the first sliding block 410 and the top surface of the first sliding groove, and the first sliding block 410 is pressed against the bottom surface of the first sliding groove under the action of the first elastic member 420. The protrusions are clamped in the grooves, and the protrusions can be disengaged from the grooves when the lifting rod 400 is pushed up. Of course, in other embodiments, the friction between the first sliding block 410 and the first sliding groove can be increased by enlarging the anti-skid pads.

[0039] In use, in the normal state, the protrusions are clamped in the grooves. When it is necessary to move the position of the press-fit block 500, the lifting rod 400 is first pushed up to allow the protrusions to disengage from the grooves, and then the lifting rod 400 is moved. When the press-fit block 500 is moved to the desired position, the lifting rod 400 is released, and the first sliding block 410 is lowered under the action of the first elastic member 420, and the protrusions are reinserted into the grooves. Thus, the press-fit block 500 can be prevented from sliding arbitrarily during the press-fitting process, thereby ensuring stable press-fitting.

[0040] As another preferred embodiment, the clamp 300 further comprises a second sliding block 320. A plurality of second sliding grooves extending radially along the positioning hole are formed at intervals on the workbench 200, and the bottom end of each clamp 300 is provided with a second sliding block 320. The second sliding block 320 is clamped in the second sliding groove in a slidable manner. In use, since the clamp 300 can move radially, it can be adapted to the press-fitting of tires of different diameters.

[0041] In specific implementation, the clamp 300 further comprises a second elastic member 330. The second elastic member 330 is arranged in the second sliding groove and located away from the positioning hole. The second elastic member 330 is connected between the second sliding block 320 and the side wall of the second sliding groove away from the positioning hole.

[0042] The second elastic member 330 can provide a certain pressing force to the clamp 300 when the clamp 300 is clamped to the outer wall of the rim 2, thereby improving the pressing effect on the rim 2.

[0043] In addition, in specific implementation, an inwardly inclined hook plate 340 can be arranged on the top of the limiting block 310. After the rim 2 is installed on the installation table, the hook plate 340 can be hooked in the rim groove of the rim 2. The hook plate 340 can further improve the clamping stability of the clamp 300.

[0044] The use mode of the tire press-fitting device is as follows:

[0045] In use, first, the tower base 1, the hub, the rim 2, the spoke are assembled, then pull the clamp 300 to the tower base 1 end can be inserted into the positioning hole, make all the clamp 300 abut on the lower edge of the rim 2, then place the tire on the rim 2, and the tire air nozzle is inserted into the corresponding hole of the rim 2, then push the lifting rod 400 and move the lifting rod 400, the guide part 510 is moved to the destination, at this time, the lower end surface of the guide part 510 is flush with the upper surface of the rim 2, and the lower surface of the guide part 520 is flush with the upper outer ring of the rim groove; then manually press the tire, so that part of the tire is below the guide part 510 and the guide part 520, then rotate the rim 2 to the guide part 520 direction, in the rotating process, the guide part 510 presses the edge of the tire, with the tire continuing to rotate, the pressed part is guided into the rim groove under the action of the guide part 520, with the continuous rotation of the rim 2, until the whole tire is completely fitted in the rim groove, then move the lifting rod 400 radially, the whole tire is taken off, and the assembly of the tire is completed.

[0046] The tire press-fitting device has the advantages that the positioning of the clamp can guide the guide part and the guide part in the press-fitting process, so that the tire can be quickly installed in the rim groove, and the whole device has simple structure and convenient operation.
