[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0034] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0035] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0036] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0037] Example 1

[0038] Reference Figures 1 to 8 , which is the first embodiment of the present invention, provides a tire disassembly method for automobile inspection and maintenance, which can achieve that when faced with a variety of threaded sleeves of different specifications, workers do not need to frequently change tools for disassembling threaded sleeves, and can directly disassemble different threaded sleeves, thereby improving disassembly efficiency.

[0039] First, adjust the length of the telescopic rod 107c and use the disassembly mold 107h to disassemble the screw sleeve, and then push and drop the disassembled tire onto the surface of the arc plate 201d;

[0040] First, the height of the support frame 101 is adjusted by using the support device 100, and then the screw sleeve on the tire surface is removed by using the disassembly assembly 107. After the screw sleeve is removed, the tire is pushed out by using the push-out mechanism 300 and falls onto the surface of the arc plate 201d.

[0041] When the threaded sleeve on the tire surface needs to be removed, the worker needs to align the removal mold 107h with the threaded sleeve, and then squeeze the removal mold 107h against the surface of the threaded sleeve through the operation of the electric push rod 405, and then use the spring 107g to expand it, which can adapt to the removal of threaded sleeves of the same model but different sizes.

[0042] Example 2

[0043] Reference Figures 1 to 8 , which is the second embodiment of the present invention, provides a protection mechanism 200 to protect the disassembly mold 107h when the tire is pushed and dropped.

[0044] The protective mechanism 200 is arranged on one side of the support frame 101. The protective mechanism 200 includes an unfolding component 201. The unfolding component 201 includes a stroke column 201a arranged on one side of the support frame 101. The left and right sides of the stroke column 201a are penetrated by unfolding plates 201b. An inclined plate 201c is arranged on the opposite side of the unfolding plate 201b, and an arc plate 201d is arranged on the opposite side of the unfolding plate 201b. A protective plate 201e is arranged on the rear side of the unfolding plate 201b. A rotating component 201f is arranged at the bottom of the unfolding plate 201b. The rotating component 201f includes a rotating component arranged on the arc plate 201d. The first tooth plate 201f-1 is at the bottom of the shaped plate 201d, and the surface of the first tooth plate 201f-1 is meshed with the first gear 201f-2, the top of the first gear 201f-2 is provided with a first pulley 201f-3, the surface of the first pulley 201f-3 is connected to the second pulley 201f-4 through a belt transmission, and the bottom of the second pulley 201f-4 is provided with a second gear 201f-5, and the bottom of the first gear 201f-2 and the second gear 201f-5 are both provided with a connecting member 201f-6, and the top of the connecting member 201f-6 is connected to the bottom of the support frame 101.

[0045] Specifically, after the tire is disassembled, the tire can be automatically pushed down to the surface of the arc plate 201d, and the disassembly mold 107h can be reset to drive the unfolding plate 201b to reset. When the tire is automatically pushed down to the surface of the arc plate 201d, the disassembly mold 107h can be protected.

[0046] Furthermore, when the electric push rod 405 is running, the plug-in slot will be driven to move by the plug-in rod 406, and the second tooth plate 407-1 will be driven to move by the movement of the plug-in sleeve 407. The second gear 201f-5 will be rotated by the movement of the second tooth plate 407-1. When the second gear 201f-5 rotates, the second pulley 201f-4 will be used to drive the first pulley 201f-3 to rotate by the belt, thereby driving the first gear 201f-2 to rotate. Since the first gear 201f-2 is meshed with the first tooth plate 201f-1 on its surface, and during the rotation of the first gear 201f-2, the first tooth plate 201f-1 will be driven to the opposite direction. The second gear 201f-5 rotates in the opposite direction, thereby driving the unfolding plate 201b to move in the opposite direction, so as to provide a path for disassembling the screw sleeve of the disassembly mold 107h. After the screw sleeve is completely disassembled, the worker docks the plug rod 406 and the plug sleeve 407 again, and uses the operation of the electric push rod 405 to drive the fixed plate 107d to reset. When the electric push rod 405 runs again and returns to the inside of the plug sleeve 407 through the plug rod 406, it can drive the second tooth plate 407-1 to move again, so that the second gear 201f-5 rotates in the opposite direction, thereby driving the unfolding plate 201b to move in the opposite direction, so as to protect the disassembly mold 107h when the tire falls off.

[0047] Example 3

[0048] Reference Figure 1 , 4 8 is a third embodiment of the present invention, which provides a push-out mechanism 300, which can automatically squeeze and remove the tire after the threaded sleeve on the tire surface is completely removed.

[0049] The extrusion assembly 301 includes an electric cylinder 301a arranged on the top of the support plate 103, and a connecting sleeve 301b is provided at the output end of the electric cylinder 301a. Pulling rods 301c are passed through the left and right sides of the connecting sleeve 301b, and the pulling rod 301c is slidably connected to the surface of the extrusion rod 301e through the pulling groove 301d, and the pulling groove 301d is opened on the left and right sides of the extrusion rod 301e; driving grooves 408 are opened on the front and back sides of the extrusion rod 301e, and a driving rod 409 is provided on the surface of the driving groove 408, and one side of the driving rod 409 is fixedly connected to one side of the arc plate 201d, and a support member 410 is provided on the top of the support plate 103, and the left and right sides of the support member 410 pass through the left and right sides of the extrusion rod 301e, and the extrusion rod 301e is in a movable state.

[0050] Specifically, after the screw sleeve on the surface of the tire is completely removed, the tire can be automatically pushed out and dropped onto the surface of the unfolding plate 201b, reducing the need for workers to remove it manually and avoiding injuries to workers who fail to hold the tire firmly due to its heavy weight.

[0051] Furthermore, when the electric push rod 405 stops running, the operation of the electric cylinder 301a can drive the pulling rod 301c to be squeezed on the surface of the pulling groove 301d, so that the squeezing rod 301e squeezes one side of the tire with the connecting part 201f-6 as the center, so that the tire falls onto the surface of the arc plate 201d after being squeezed by one side, completing the disassembly.

[0052] The remaining structure is the same as that of Example 2.

[0053] Example 4

[0054] Reference Figures 1 to 8 , which is the fourth embodiment of the present invention. This embodiment is different from the third embodiment in that: this embodiment provides a tire removal device for automobile inspection and maintenance.

[0055] When using the device;

[0056] Workers are required to use telescopic columns to adjust the support frame 101 to a suitable height, and then start the electric push rod 405. When the electric push rod 405 is running, it can drive the fixed plate 107d, the extension plate and the telescopic rod 107c to move together and move them to the position of the screw sleeve. When the screw sleeve needs to be disassembled, the worker starts the motor 107b, which can drive the telescopic rod 107c to rotate during electric operation, and the rotation of the telescopic rod 107c can simultaneously drive the fixed plate 107d to rotate, so that the fixed plate 107d drives the extension plate 401 to rotate. At this time, since the disassembly mold 107h is squeezed by the surface of the screw sleeve, the inner wall after the spring 107g is expanded is in contact with the surface of the screw sleeve, and since the fixed rod 107f is provided to support the disassembly mold 107h, the screw sleeve can be disassembled by the disassembly mold 107h through the rotation of the motor 107b;

[0057] When the electric push rod 405 is running, the plug-in slot will be driven to move by the plug-in rod 406, and the second tooth plate 407-1 will be driven to move by the movement of the plug-in sleeve 407, and the second gear 201f-5 will be rotated by the movement of the second tooth plate 407-1. When the second gear 201f-5 rotates, the first pulley 201f-3 will be rotated by the second pulley 201f-4 using the belt drive, thereby driving the first gear 201f-2 to rotate. Since the surface of the first gear 201f-2 is meshed with the first tooth plate 201f-1, and during the rotation of the first gear 201f-2, the first tooth plate 201f-1 will be driven to move in the opposite direction, thereby driving the unfolding plate 201b to move in the opposite direction, which is used to provide a path for disassembling the screw sleeve of the disassembly mold 107h;

[0058] After the screw sleeve is completely removed, the worker re-joins the plug rod 406 and the plug sleeve 407, and uses the operation of the electric push rod 405 to reset the fixed plate 107d. When the electric push rod 405 is running again and returns to the inside of the plug sleeve 407 through the plug rod 406, it can drive the second gear plate 407-1 to move again, so that the second gear 201f-5 rotates in the opposite direction, thereby driving the expansion plate 201b to move in the opposite direction. When the electric push rod 405 stops running, the operation of the electric cylinder 301a can drive the pulling rod 301c to squeeze the surface of the pulling groove 301d, so that the squeezing rod 301e squeezes one side of the tire with the connecting piece 201f-6 as the center, so that the tire is squeezed by one side and falls onto the surface of the arc plate 201d, completing the disassembly.

[0059] In summary: when the tire needs to be installed, the arrangement of the inclined plate 201c in the present application facilitates the installation of the tire, and also facilitates the removal of the tire by dropping it onto the surface of the arc plate 201d.
