[0013] Compared with the prior art, the utility model has the following outstanding and beneficial technical effects:

[0014] 1. The tire pressing machine provided by the utility model places the tire against the working surface, drives the connecting rod by driving the cylinder, and the connecting rod drives the tire pressing plate to press the tire on the working surface, so that the tire can be easily separated from the wheel hub from the connection. The overall operation is simple and the structure is simple.

[0015] 2. The utility model further provides a beading plate which is operated and rotated by an operating lever, thereby facilitating the beading plate to be embedded in the connection between the tire and the wheel hub. This is not only more convenient in operation but also has a wider range of applications.

[0016] 3. The utility model further provides a beading plate, which is chamfered to prevent the tire from being punctured when the beading plate is embedded. At the same time, the long side contacts the tire, which reduces the pressure and prevents the tire surface from being punctured.

[0017] 4. The utility model further arranges the box body as the cylinder frame, which provides certain protection for the cylinder. At the same time, a pedal switch is arranged to make the operation more convenient for the user.

[0018] 5. The arc-shaped connecting rod provided by the utility model enables the horizontally placed cylinder to make the tire bead plate act on the action surface of the cylinder frame in a vertical manner when operating the piston rod. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The present invention will be further described below with reference to the accompanying drawings. Figure 1 — Figure 3 :

[0029] A miniature tire pressing machine comprises a cylinder frame 1 with a horizontally placed cylinder 2 fixed inside, a working surface 10 for abutting against a tire is arranged on one side of the cylinder frame 1, a support frame 3 is arranged on one side of the cylinder frame 1 located on a cylinder piston rod 20, a longitudinally arranged articulated vertical shaft 30 is arranged on the support frame 3, a connecting rod 4 is movably hinged on the top of the articulated vertical shaft 30, one end of the connecting rod 4 is hingedly connected to the end of the cylinder piston rod 20, and a tire pressing plate 5 is arranged on the other end of the connecting rod 4. When the cylinder 2 drives the cylinder piston rod 20 to move outward, the connecting rod 4 rotates along the articulated vertical shaft 30 and drives the tire pressing plate 5 to vertically press toward the working surface 10.

[0030] The specific tire pressing operation is:

[0031] The operator places the tire assembly to be repaired against the working surface 10, drives the air cylinder, and allows the cylinder piston rod 20 of the air cylinder to drive the connecting rod to rotate along the hinged vertical axis 30. After the rotation, the tire pressing plate 5 presses the tire against the connection between the tire and the wheel hub, so that the tire falls off the wheel hub, which is convenient for the subsequent tire removal operation. It is easy to operate and is very suitable for the tire removal operation of household cars.

[0032] Preferably, a movable sleeve 40 is fixed to the end of the connecting rod 4, a movable shaft 50 inserted into the movable sleeve 40 is fixed to the side of the tire pressing plate 5, and an operating rod 51 is fixed to the upper end of the movable shaft 50. When the operating rod 51 drives the movable shaft 50 to rotate along the movable sleeve 40, the tire pressing plate 5 rotates along the axial direction of the movable shaft 50.

[0033] In the above structure, the tire pressing plate 5 can rotate to a certain extent at the end of the connecting rod according to the rotation of the operating rod 51, so as to facilitate the operator to calibrate the connection position between the tire and the wheel hub, which is more convenient to operate and has a wide range of applications.

[0034] Preferably, the tire beating plate 5 is an arc plate, the arc plate is in the shape of an isosceles trapezoid, and the active end of the tire beating plate 5 embedded in the tire is the long side of the arc plate.

[0035] Preferably, the corners of the tire pressing plate 5 are rounded.

[0036] The trapezoidal structure design can squeeze the long side with smaller pressure when pressed into the joint to avoid tire puncture, and the rounded corners are the same. And the curved plate design can be applicable to the curved joints to a certain extent.

[0037] Preferably, the cylinder frame 1 is a box structure, a cylinder bracket 11 is arranged inside the cylinder frame 1, and the cylinder 2 is transversely placed on the cylinder bracket 11 by bolts.

[0038] Preferably, a switch opening 12 is provided below the cylinder frame 1 , and a pedal switch 6 for controlling the movement of the cylinder piston rod 20 is provided in the switch opening 12 .

[0039] In the above structure, the design of the box body can provide certain protection for the cylinder, and the cylinder bracket 11 can fix the cylinder more firmly; and the switch is provided to facilitate the operator to control the cylinder with his feet, so as to facilitate the tire pressing operation.

[0040] Preferably, the connecting rod 4 is in an arc shape. The arc-shaped connecting rod design can facilitate the bead plate to act vertically on the surface of the working surface.

[0041] Working principle:

[0042] The miniature tire pressing machine provided by the utility model utilizes the simple principle of the cylinder to drive the tire pressing plate to squeeze the connection between the tire and the wheel hub, thereby achieving the tire pressing effect. The overall structure is simple, the operation is convenient, and it is very suitable for the tire pressing operation of household vehicles, which is convenient for the subsequent tire removing operation.
