Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] Example 1:

[0024] As attached Figure 1-4 As shown, in a preferred embodiment, based on the above method, it further includes a tire press body 1, an operating platform 2 on the tire press body 1, a wheel hub 3 placed on the operating platform 2, a guide cylinder 12 placed on the wheel hub 3, and a tire 4 connected to the upper end of the guide cylinder 12. A hydraulic device 9 is provided on the tire press body 1, and a fixing plate 10 is connected to the lower end of the hydraulic device 9. A lower pressure plate 11 is provided below the fixing plate 10, and the lower pressure plate 11 is connected to the fixing plate 10. The plates 10 are connected by connecting rods 14. The lower pressure plate 11 has a ring-shaped structure and a fixed cylinder 8 is inserted inside the lower pressure plate 11. The upper end of the fixed cylinder 8 is connected to the fixed plate 10, and a high-pressure nozzle 13 is provided on the lower side of the fixed cylinder 8. A pressurizing device 5 and an oil storage tank 6 are provided on one side of the tire pressurizer body 1. A conduit 7 is connected between the pressurizing device 5, the oil storage tank 6 and the fixed cylinder 8. An installation hole 17 is opened on the hub 3 and the installation hole 17 is located on the vertical axis of the hub 3.

[0025] Example 2:

[0026] The following description further illustrates one embodiment of the solution, with a detailed explanation of its working method.

[0027] As attached Figure 1 and 4As shown, in a preferred embodiment, based on the above method, a positioning rod 16 is further provided at the middle position on the operating platform 2, and the diameter of the positioning rod 16 is smaller than the mounting hole 17. When the wheel hub 3 is placed on the operating platform 2, the wheel hub 3 can be sleeved on the outside of the positioning rod 16 through the mounting hole 17 to position the wheel hub 3, which can prevent the wheel hub from moving around when pressing the tire.

[0028] As attached Figure 1 As shown, in a preferred embodiment, based on the above method, the vertical cross-sectional width of the lower pressure plate 11 is equal to the vertical cross-sectional width of the tire 4, and the outer diameter of the lower pressure plate 11 is equal to the outer diameter of the tire 4. When the lower pressure plate 11 presses down on the tire 4, it can apply force evenly to the outer edge of the tire 4 without interfering with the pressing operation of the tire 4. The outer side of the guide cylinder 12 is a combination of conical and cylindrical structure, and the inside of the guide cylinder 12 is provided with an inverted "T" shaped through hole 15. The outer dimensions of the large end of the through hole 15 match the outer dimensions of the wheel hub 3. The inner side of the lower end of the guide cylinder 12 can be fitted into the outside of the wheel hub 3, so that the guide cylinder 12 can cover the outside of the wheel hub 3. When the tire 4 moves downward along the outside of the guide cylinder 12, the inner diameter of the tire 4 will temporarily expand due to elasticity. When the tire 4 reaches the bottom of the guide cylinder 12, the position of the tire 4 is fixed. When the guide cylinder 12 is pulled upward, the tire 4 can be fixed in the groove of the wheel hub 3 due to elasticity.

[0029] As attached Figure 2 As shown, in a preferred embodiment, based on the above method, the outer diameter of the small end of the guide cylinder 12 is smaller than the inner diameter of the tire 4. The tire 4 can be sleeved downward along the small end of the guide cylinder 12 on the outside of the guide cylinder 12, so that it can move downward along the downward pressure of the lower pressure plate 11.

[0030] As attached Figure 2 and 3 As shown, in a preferred embodiment, based on the above method, the high-pressure nozzles 13 are further distributed evenly along the annular direction at the lower end of the fixed cylinder 8, and the installation direction of the fixed cylinder 8 is inclined downward from the inside to the outside. The maximum diameter at the outer end of the annularly distributed high-pressure nozzles 13 is smaller than the diameter at the small end of the through hole 15. The high-pressure nozzles 13 at the lower end of the fixed cylinder 8 can enter the tire 4 and the through hole 15, avoiding interference of the high-pressure nozzles 13 with the pressing operation of the tire 4. The downwardly inclined high-pressure nozzles 13 can conveniently and evenly spray the degreaser onto the inner side of the tire 4. Five connecting rods 14 are provided, and the diameter of the connecting rods 14 is equal to the width of the vertical section of the lower pressure plate 11. The connecting rods 14 are evenly distributed along the annular direction between the lower pressure plate 11 and the fixed plate 10, which can make the lower pressure plate 11 bear force evenly and conveniently apply force downward to the tire 4 evenly.

[0031] Working principle: First, place the wheel hub 3 on the operating platform 2 of the tire press body 1, so that the mounting hole 17 fits into the outside of the positioning rod 16 to position the wheel hub 3. Then, put the guide cylinder 12 on top of the wheel hub 3, and then place the tire 4 on top of the guide cylinder 12. Start the hydraulic device 9, so that the hydraulic device 9 drives the fixing plate 10 to move downward. The fixing plate 10 drives the lower pressure plate 11 to move downward through the connecting rod 14. When the high-pressure nozzle 13 at the lower end of the fixing cylinder 8 begins to enter the tire 4, start the pressurization device 5. The pressurization device 5 will pressurize the oil tank. The degreasing agent in 6 is transported through the conduit 7 to the high-pressure nozzle 13 and sprayed onto the inside of the tire 4. Then the pressurizing equipment 5 is stopped, and the lower pressure plate 11 will drive the tire 4 to continue moving downward along the guide cylinder 12. At this time, the high-pressure nozzle 13 will enter the through hole 15 without interfering with the pressing work. The tire 4 will temporarily expand its inner diameter due to elasticity. When the tire 4 reaches the bottom of the guide cylinder 12, the lower pressure plate 11 is lifted upward, and then the position of the tire 4 is fixed. The guide cylinder 12 is pulled upward, and the tire 4 can be fixed in the groove of the wheel hub 3 due to elastic contraction, thus completing the pressing work.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
