Among them: 1-frame, 2-tire bracket, 3-base, 4-universal wheel, 5-hydraulic jack, 6-adjustable screw, 7-push handle, 8-I-shaped bracket, 9-slide, 10- Lower beam, 11-guide rod, 12-roller, 13-threaded hole, 14-guide hole.

Detailed ways

The three-dimensional view of the tire disassembly and assembly assist device of the present utility model is shown in FIG. 1, including a vertical frame 1, a tire support 2, a horizontal base 3, a universal wheel 4, a hydraulic jack 5, an adjustable screw 6, a push handle 7, an I-shaped Type bracket 8, slideway 9, lower beam 10, etc. Taking the direction of operation as the front, the frame 1 includes two left and right uprights, and two pushers 7 are welded on the left and right uprights. A slideway 9 is processed on the inner side of the frame column. The horizontal base 3 is fixed to the frame 1 by welding, and the universal wheel 4 is fixed under the base 3 to adjust the moving direction. A slidable movable bracket is installed in the slideway 9, and the movable bracket includes an I-shaped bracket 8 and a lower beam 10. The I-shaped bracket 8 and the lower beam 10 are connected by an adjustable screw 6 and a guide rod 11, which can be adjusted. The screw 6 and the guide rod 11 are fixed on the lower beam 10, and the adjustable screw 6 is rotatable. The I-shaped bracket 8 is threadedly connected with the adjustable screw 6 and slidably connected with the guide rod 11 , so that when the adjustable screw 6 rotates, the I-shaped bracket 8 can be adjusted to move up and down under the action of the guide rod 11 . Two tire brackets 2 are installed in front of the I-shaped bracket 8 , and the tire brackets 2 are used to place the tires when dismounting the tires. The roller on the tire bracket 2 can rotate around the axis of the tire bracket through the bearing, which is convenient for adjusting the positioning of the bolts between the tire and the wheel hub in the circumferential direction. The hydraulic jack 5 connects the lower beam 10 and the base 3, and can push and pull the lower beam 10, so that the movable bracket moves quickly in the slideway 9, and can quickly adjust the height of the tire bracket 2, thereby quickly adjusting the relative position of the tire and the hub. When fine adjustment is required, the adjustable screw 6 can be used.

The rollers 12 at the left and right ends of the I-shaped bracket 8 are sleeved in the slideway 9 and cooperate with the slideway 9. See Figure 2, the I-shaped bracket 8 can be moved up and down in the slideway 9, and the two ends of the lower beam 10 can be realized. The rollers 12 are also installed to move in the slideway 9 together with the I-shaped bracket 8 . The I-shaped bracket 8 is machined with a threaded hole 13 matched with the adjustable screw 6 , and a guide hole 14 matched with the guide rod 11 .

The utility model adjusts the position of the tire bracket by adjusting the universal wheel 4, the hydraulic jack 5 and the adjustable screw 6, thereby realizing the disassembly and assembly of the tire. Taking the installation of tires as an example, the pusher pushes the tires directly under the brake of the motor vehicle, and the hydraulic jack is used to lift the tires to the specified height. Align with the bolt holes on the tire brake or brake disc for easy installation of tire bolts.

The utility model is mainly used in tire shops, automobile repair shops, etc., to realize quick disassembly and assembly of automobile tires, and improve work efficiency.
