[0023] A forward and reverse threaded screw rod 10 is rotatably connected between the two No. 1 slide grooves 5 at one end away from each other, and the two ends of the forward and reverse threaded screw rod 10 are respectively penetrated and threadedly connected to the two No. 1 sliders 6, and the forward and reverse threaded screw rod 10 is penetrated and rotatably connected to the inner wall of the base 1 between the two No. 1 slide grooves 5, and a motor is installed on the side wall of the base 1 at one end opposite to the forward and reverse threaded screw rod 10, and the output end of the motor penetrates the side wall of the base 1 and is fixedly connected to the opposite end of the forward and reverse threaded screw rod 10, so as to facilitate the straightening of the two ends of the installation belt 7 to be more stable and synchronous, reduce the occurrence of uneven force during the tire installation process, and ensure the quality and efficiency of the tire installation.

[0024] Example 2: Reference Figure 2 - Figure 4 , further improvements are made on the basis of the first embodiment:

[0025] The bottom of the hub limiting plate 4 is fixedly connected with a No. 2 slider 11, and the hub disc 3 is provided with a No. 2 slide groove 12 at the top position relative to the three No. 2 sliders 11. The No. 2 slide grooves 12 are adapted and slidably connected to the No. 2 slide grooves 12. The inner groove of the No. 2 slide groove 12 is rotatably connected with a threaded rod 13, and the threaded rod 13 penetrates and is threadedly connected to the No. 2 slider 11. The hub disc 3 is provided with a gear groove 14 at the center position of the circle relative to one end of the three threaded rods 13. A main gear 15 is rotatably provided at the bottom of the inner groove of the gear groove 14. The threaded rod 13 is fixedly connected with a secondary gear 15 at one end relative to the gear groove 14. Gear 16, main gear 15 and sub gear 16 are all bevel gears, and main gear 15 and sub gear 16 are meshed with each other. A motor is installed inside the hub disk 3 near the bottom of the main gear 15, and the motor output end is fixedly connected to the bottom of the main gear 15. The three hub limiting plates 4 drive the three sub gears 16 to rotate through the main gear 15, so that the three threaded rods 13 can rotate synchronously, and then the three hub limiting plates 4 can stably fix the wheel hub of the automobile tire to the hub disk 3 for tire installation, making the device more convenient and stable to use.

[0026] The side walls on opposite sides of the slide seat 2 are provided with slide rail grooves 18, inside of which rollers 19 are provided for rolling. A sliding block 17 is fixedly connected to the outside of the roller 19, and the sliding block 17 is fixedly connected to the side wall of the bottom of the hub disc 3 close to the slide seat 2. When the mounting belt 7 is straightened, the hub disc 3 moves under the pulling force of the mounting belt 7. During the movement, the rollers 19 roll in the slide rail grooves 18, which provides stable movement for the hub disc 3 and prevents the hub disc 3 from detaching from the slide seat 2.

[0027] The working principle of the utility model is as follows: when in use, the tire wheel hub is placed above the wheel hub disc 3, and the wheel hub limiting plate 4 is placed on the inner side of the bottom of the wheel hub, and then the motor at the bottom of the main gear 15 is started, and the motor drives the main gear 15 to rotate, and the main gear 15 rotates the sub-gear 16 through meshing transmission, and the sub-gear 16 drives the relative threaded rod 13 to rotate, and the three threaded rods 13 rotate synchronously, and then the threaded rod 13 drives the second slider 11 to move in the second slide groove 12, at this time, the wheel hub limiting plate 4 moves driven by the second slider 11, and the three wheel hub limiting plates 4 move synchronously in the outward direction, and the wheel hub limiting plate 4 moves to the inner arc wall of the wheel hub for fitting and extrusion, so that the wheel hub is fixed to the wheel hub disc 3, and then the middle section of the mounting belt 7 is passed through the middle hole of the tire rubber carcass, and then the mounting belt 7 is sleeved to the outer side of the wheel hub above the wheel hub disc 3, and then After that, the tire carcass is moved to a position above the wheel hub in an inclined state, and then the motor on the side wall of the machine base 1 is started to drive the forward and reverse threaded screws 10 to rotate. The forward and reverse threaded screws 10 drive the two No. 1 sliders 6 to move oppositely in the two No. 1 slide grooves 5, and the two No. 1 slide grooves 5 begin to lengthen the mounting belt 7. At this time, the mounting belt 7 will squeeze and stretch outward to contact the rubber carcass. The position where the rubber carcass is stretched and widened can be quickly sleeved on the outside of the wheel hub until the mounting belt 7 is completely straightened, so that the rubber carcass is completely sleeved on the outside of the wheel hub. During the process, the wheel hub disc 3 will move toward the side of the baffle 8 as the mounting belt 7 is gradually straightened. At this time, the spring 9 is used to provide a reaction force in the moving direction to the wheel hub disc 3, so that the process of the mounting belt 7 sleeves the rubber carcass on the outside of the wheel hub is more stable, preventing the wheel hub disc 3 from moving too fast, which may cause the problem of improper installation of the rubber carcass.

[0028] The motors in the above embodiments are all applications of the prior art and will not be described in detail here.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
