[0035] Reference Figure 1-4 As shown, an embodiment of the present application provides a steering wheel disassembly device, which includes a positioning block 1, a connecting assembly and a push rod 5. The connecting assembly is connected to the positioning block 1, and is used to connect with the steering wheel to limit the relative movement of the positioning block 1 and the steering wheel in the axial and radial directions of the steering wheel. The push rod 5 is threadedly connected to the positioning block 1. When the connecting assembly is connected to the steering wheel, the push rod 5 is coaxial with the steering wheel, and is suitable for being supported by the steering wheel connecting shaft through the push rod 5, and driving the steering wheel to move axially relative to the connecting shaft when rotating relative to the positioning block 1.

[0036] Reference Figure 1-2 As shown, specifically, the shape and size of the positioning block 1 are configured according to the shape. In order to realize its connection with the steering wheel, the connecting assembly includes two fixed connecting rods 2 and one movable connecting rod 3. The axes of the fixed connecting rods 2 and the movable connecting rod 3 are both perpendicular to the axis of the push rod 5. One end of the fixed connecting rod 2 is connected to the positioning block 1, and the other end is bent to form a hook 4 for hooking on the steering wheel. The movable connecting rod 3 also has one end connected to the positioning block 1, and the other end is bent to form a hook 4 for hooking on the steering wheel. The movable connecting rod 3 and the two fixed connecting rods 2 are circumferentially spaced along the push rod 5, and the movable connecting rod 3 can move relative to the positioning block 1 along its axial direction. Specifically, the fixed connecting rod 2 and the movable connecting rod 3 are both connected to the positioning block 1 at one end and extend away from the positioning block 1 and bend to form a hook 4 at the other end. In this embodiment, the axes of the fixed connecting rod 2 and the movable connecting rod 3 intersect with the axis of the top rod 5, and the angles between the two fixed connecting rods 2 and the movable connecting rod 3 are both 120°. In this way, when the fixed connecting rod 2 and the movable connecting rod 3 are connected to the steering wheel and force is applied to the steering wheel in the axial direction of the steering wheel, the steering wheel is evenly stressed in the circumferential direction, thereby avoiding damage to the steering wheel caused by excessive local force.

[0037] Reference Figure 1-2As shown, in order to facilitate the connection of the device to the steering wheel, the movable connecting rod 3 is set to be movable axially relative to the positioning block 1. In actual operation, the movable connecting rod 3 is moved away from the positioning block 1, so that the distance between the hook 4 of the fixed connecting rod 2 and the hook 4 of the movable connecting rod 3 is increased, and the device can be moved axially along the steering wheel until the fixed connecting rod 2 and the movable connecting rod 3 are in contact with the steering wheel, and then moved radially until the hook 4 of the fixed connecting rod 2 is hooked on the steering wheel, and then the movable connecting rod 3 is moved until it is hooked on the steering wheel and locked, thereby completing the connection between the device and the steering wheel.

[0038] Reference Figure 1-3 As shown, specifically, the movable connecting rod 3 is connected to the positioning block 1 through a connecting structure, and the connecting structure includes a fixing rod 6 and a connecting bolt 7. The axis of the fixing rod 6 is parallel to the axis of the movable connecting rod 3. One end of the fixing rod 6 is fixed to the positioning block 1. The fixing rod 6 is provided with an adjustment slot 61 extending along its axial direction. The adjustment slot 61 is axially penetrated in the push rod 5. The connecting bolt 7 passes through the movable connecting rod 3 and the adjustment slot 61 and then connects with a nut. When the nut is loose, the movable connecting rod 3 can be moved along the length direction of the adjustment slot 61, that is, the movable connecting rod 3 can be moved axially relative to the positioning block 1, or the movable connecting rod 3 and the fixing rod 6 can be locked by tightening the nut, so that the device can be stably connected to the steering wheel.

[0039] In other embodiments, the fixed connecting rods 2 may be replaced by movable connecting rods 3 to accommodate the disassembly of steering wheels of different specifications and sizes.

[0040] Reference Figure 1-2 As shown, further, the push rod 5 passes through the positioning block 1 and is threadedly connected to the positioning block 1. One end of the push rod 5 is set to be semi-spherical, which is used to contact the connecting shaft to reduce the resistance when relative to the connecting shaft rotates. The other end of the push rod 5 is set to have a polygonal cross-section, so as to facilitate driving the push rod 5 to rotate by a wrench or other device.

[0041] Reference Figure 4 As shown, when the steering wheel disassembly device of the present application is in use, the nut connected to the connecting screw is first loosened, and the movable connecting rod 3 is moved away from the positioning block 1 until the device can be moved axially along the steering wheel until the fixed connecting rod 2 and the movable connecting rod 3 are in contact with the steering wheel, and then the device is moved radially along the steering wheel until the hook 4 of the fixed connecting rod 2 is hooked on the steering wheel, and then the movable connecting rod 3 is moved until it is hooked on the steering wheel and locked, thereby completing the connection between the device and the steering wheel; rotate the push rod 5 until the hemispherical end abuts against the end of the connecting shaft, and continue to rotate the push rod 5 to generate a reverse force on the positioning block 1 and the steering wheel, driving the steering wheel to move axially along the connecting shaft until it is separated from the connecting shaft, thereby completing the disassembly of the steering wheel.

[0042] In order to avoid damaging the steering wheel, rubber pads are provided on the contact surfaces of the movable connecting rod 3 and the fixed connecting rod 2 with the steering wheel.

[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
