[0047] The motorcycle front shock absorber inner and outer tube tightening device is a device for tightening the inner and outer tubes of the motorcycle front shock absorber, and can quickly tighten the motorcycle front shock absorber.

[0048] In the related art, the inner and outer tubes of the motorcycle front shock absorber are generally tightened and fixed by relevant professionals using professional tools, which requires a lot of manpower and cannot be tightened quickly.

[0049] Based on this, in order to improve the problem of requiring a lot of manpower costs and low tightening efficiency in the related technology, the embodiment of the present application provides the following solution.

[0050] Please also read Figure 1 and Fig.12 The embodiment of the present application provides a motorcycle front shock absorber inner and outer tube tightening device 100, including a frame 10, a first tightening part 20, a second tightening part 30, a linkage mechanism 40 and a power input device 50.

[0051] The frame 10 defines a first space 110 , and the first space 110 is communicated with the external space.

[0052] The first tightening portion 20 is disposed in the first space 110 and is used to tighten one end of the inner and outer tubes of the motorcycle front shock absorber.

[0053] The second tightening portion 30 is disposed in the first space 110 and is used to tighten the other end of the inner and outer tubes of the motorcycle front shock absorber.

[0054] The linkage mechanism 40 is disposed in the first space 110 and is transmission-connected to the first tightening portion 20 and the second tightening portion 30 respectively.

[0055] The power input device 50 is disposed on the frame 10 , and the power input device 50 is connected to the linkage mechanism 40 .

[0056] Among them, when the power input device 50 is driven forward, the power input device 50 drives the first tightening part 20 and the second tightening part 30 through the linkage mechanism 40 to tighten the inner and outer tubes of the motorcycle front shock absorber; when the power input device 50 is driven reversely, the power input device 50 drives the first tightening part 20 and the second tightening part 30 through the linkage mechanism 40 to release the tightening operation on the inner and outer tubes of the motorcycle front shock absorber.

[0057] It can be understood that the frame 10 is used to install mechanisms such as the first tightening part 20, the second tightening part 30, the linkage mechanism 40 and the power input device 50. The frame 10 can be set as a square cabinet or an elliptical cabinet, etc.; the first tightening part 20 is used to tighten one end of the inner tube of the motorcycle shock absorber. For example, the first tightening part 20 can be set as a device in which a wrench and a gear cooperate, and the linkage mechanism 40 drives the wrench to tighten the inner tube of the motorcycle shock absorber through the gear; for another example, a device in which a wrench cooperates with a movable and rotatable mechanism drives the wrench through the movable and rotatable mechanism so that the wrench tightens the inner tube of the motorcycle shock absorber; the second tightening part 30 is used to tighten one end of the outer tube of the motorcycle shock absorber. For example, the second tightening part 30 can be set as a device in which a wrench and a gear cooperate, and the linkage mechanism 40 drives the wrench to tighten the outer tube of the motorcycle shock absorber through the linkage mechanism 40; for another example, the wrench is connected to a movable and rotatable mechanism. , a wrench is driven by a movable and rotatable mechanism so that the wrench can tighten the outer tube of the motorcycle shock absorber; the linkage mechanism 40 is used to transmit the power of the power input device 50 to the first tightening part 20 and the second tightening part 30 at the same time. For example, the linkage mechanism 40 can be set as a device in which multiple gears are connected to a connecting shaft, one of which is transmission-connected to the first tightening part 20, another gear is transmission-connected to the second tightening part 30, and the connecting shaft is transmission-connected to the power input device 50; for another example, a device in which multiple gears are connected to a connecting shaft, a line connecting the center points of the multiple gears coincides with the connecting shaft, one of which is transmission-connected to the first tightening part 20, another gear is transmission-connected to the second tightening part 30, and the last gear is transmission-connected to the power input device 50; the power input device 50 is used to input power to the tightening device 100 of the inner and outer tubes of the motorcycle front shock absorber, and the power input device 50 can be set as an electric motor or a small internal combustion engine.

[0058] As can be seen from the above, the motorcycle front shock absorber inner and outer tube tightening device 100 provided in the embodiment of the present application is provided with a frame 10 having a first space 110 connected to the external space, a first tightening part 20 arranged in the first space 110, a second tightening part 30 arranged in the first space 110, a linkage mechanism 40 connected to the first tightening part 20 and the second tightening part 30, and a power input device 50 arranged on the frame 10 and connected to the linkage mechanism 40; by placing the inner and outer tubes of the motorcycle front shock absorber between the first tightening part 20 and the second tightening part 30, the power input device 50 tightens the first tightening part 20 and the second tightening part 30 through the linkage mechanism 40. The first tightening part 20 and the second tightening part 30 simultaneously tighten the two fasteners (such as hexagonal screws) at both ends of the inner and outer tubes of the motorcycle front shock absorber; this replaces the professional personnel who use professional tools to tighten the inner and outer tubes of the motorcycle front shock absorber, and improves the efficiency of tightening the inner and outer tubes of the motorcycle front shock absorber; the power input device 50 simultaneously drives the first tightening part 20 and the second tightening part 30 through the linkage mechanism 40 to release the tightening operation of the inner and outer tubes of the motorcycle front shock absorber, so that after the tightening operation is completed, the inner and outer tubes of the motorcycle front shock absorber can be taken out of the motorcycle front shock absorber inner and outer tube tightening device 100 in time.

[0116] When the first transmission gear assembly 21 drives the first pushing member 275 to rotate in the opposite direction through the first transmission rod 24, the first pushing member 275 disengages from the first pushing fitting member 274, so that the first pushing fitting member 274 and the first tightening member 273 move in the direction away from the inner and outer tubes of the motorcycle's front shock absorber under the action of the first spring 276, and then the first tightening member 273 retracts into the first movable opening 272 to release the fit with the hexagonal screw at one end of the inner and outer tubes of the motorcycle's front shock absorber.

[0117] It can be understood that the first tightening device 271 is used to drive the first tightening member 273 to rotate, and the first tightening device 271 can be set as a cylinder, a cone or a cuboid.
