[0002] At present, most of the assembly of the gearbox shaft system and the insertion operation between the shaft system components and the gearbox housing in the factory are completed by manual operation. In particular, in the insertion operation, several gearbox shaft systems and shift forks that need to be assembled together are assembled together according to the correct assembly relationship to form a gearbox shaft system component, which is inserted into the gearbox housing as a whole. During the entire insertion process, the assembled gearbox shaft system component must be grabbed from the operating table and moved to the insertion position, and the axis of the gearbox shaft system component must be rotated from horizontal to vertical, as well as the up and down insertion movement.

[0003] According to the current design situation in the industry, in order to realize the rotation operation of a shaft of the gearbox shaft system assembly, lock the position to prevent disengagement when it is rotated into place (referred to as "stuck position" in this article), and be able to easily and quickly switch the rotation and locking states, the design of separating the rotation and locking functions is basically adopted. That is, when in use, two actions are required to complete the operation, such as rotating the operating handle + inserting the limit pin or tightening the locking screw, which makes the operation complicated. The operator needs to bear the weight of the shaft system and it is time-consuming and laborious. There is a large number of errors, and the safety of the operator and the shaft system cannot be guaranteed. Utility Model Content

[0032] The rotating shaft 3 is connected to the handle 9 through the connecting plate 4 and the hinge body 8. The rotating shaft 3 is installed in the bushing 2. The bushing 2 is installed on the main board 1. The rotating shaft 3 rotates in the bushing 2 under the driving of the horizontal rotation of the handle 9.

[0033] A through hole is provided on one end of the main board 1, and the bushing 2 is installed in the through hole. The bushing 2 and the main board 1 are fixedly installed by screws. The bushing 2 is a T-shaped structure, and a through hole is provided inside the bushing 2. The rotating shaft 3 is installed in the through hole with a gap, and rotates in the bushing 2 under driving;

[0034] One side of the connecting plate 4 is fixedly connected to the rotating shaft 3, and the other side of the connecting plate 4 is connected to the hinge body 8; one end of the hinge body 8 is connected to the handle 9.

[0035] One end of the locking pin 7 passes through the connecting plate 4 and is connected to the hinge body 8, and the other end of the locking pin 7 is installed on the main board 1; the locking pin 7 is installed on the connecting plate 4 with a gap. The locking pin 7 is connected to the hinge body 8 through the second hinge pin 6; when the handle 9 rotates up and down, the hinge body 8 is driven to rotate synchronously;

[0036] The hinge body 8 is connected to the connecting plate 4 by a first hinge pin 10. The handle 9 is rotated or pressed down up and down with the center of the first hinge pin 10 as an axis.

[0037] The rotating shaft 3 and the connecting plate 4 are connected by screws 5. The number of screws 5 in the utility model is 2.

[0038] The locking pin 7 is provided with a compression spring 11. The locking pin 7 is a cylindrical structure, and the compression spring 11 is sleeved on the outer body of the locking pin 7 and is located between the connecting plate and the main plate.

[0039] The hinge body 8 is provided with an arc groove for driving the hinge pin 6 to move;

[0040] like Figure 2 As shown, the main board 1 is provided with a travel limit groove 13, and the two sides of the travel limit groove 13 are used to limit the positioning pin 7, so that the rotating shaft 3 rotates within the working range; the travel limit groove 13 is an arc-shaped structure that matches the motion trajectory of the positioning pin 7;

[0041] The main board 1 is provided with a locking hole 12. When the handle 9 is rotated to the limit position, the locking pin 7 is locked in the locking hole 12 to limit the rotation of the rotating shaft 3. One end of the locking pin 7 extends into the travel limit groove. The locking hole 12 is provided at the end of the travel limit groove. A retaining ring is provided at the end of the locking pin 7.

[0042] The position of the locking hole and the size of the travel limit slot can be designed according to specific needs, and other structures can be directly applied, making the device highly scalable.

[0043] Example 1

[0044] The rotating shaft 3 is connected to the handle 9 through the connecting plate 4 and the hinge body 8, and can rotate in the bushing 2 installed on the main board 1 under the horizontal rotation drive of the handle 9; the hinge body 8 and the connecting plate 4 are connected by a first hinge pin 10, and the handle 9 can also rotate up and down (i.e., lift up (see attached Figure 2 ) or press down (see attached Figure 1); The hinge body 8 is also connected to the locking pin 7 by a second hinge pin 6 (which is exactly the same as the first hinge pin). When the handle 9 rotates up and down, the hinge body 8 is driven to rotate synchronously. The arc groove on the hinge body 8 drives the second hinge pin 6 to move in the arc groove. Since the second hinge pin 6 is fixed on the locking pin 7, and the locking pin 7 is installed on the connecting plate 4 with a gap, it will drive the locking pin 7 to move up and down. The function of the compression spring 11 is to make the handle 9 rotate to the top when not in operation, and the locking pin 7 is at the bottom. The locking pin and the connecting plate are matched with a moderate gap;

[0045] The function of the travel limit groove on the main board 1 is to limit the rotation of the rotating shaft 3 within the working range by limiting the positioning pins 7 on both sides thereof; the function of the positioning hole 12 on the main board 1 is that when the handle 9 is rotated to two extreme positions, that is, the operation is in place, the handle 9 will inevitably be released. At this time, under the action of the spring force, the handle 9 is automatically lifted up, and the positioning pin 7 also automatically falls downward into the positioning hole 12, thereby limiting the rotation of the rotating shaft 3.

[0046] When it is necessary to operate the rotating shaft 3 to rotate, the handle 9 is pressed downward to be close to horizontal, and the hinge body 8 rotates upward synchronously to drive the locking pin 7 (overcoming the spring force) to rise. The lowest point of the locking pin 7 will be higher than the bottom surface of the travel limit groove on the main board 1. At this time, the locking pin 7 is not restricted by the locking hole 12, and the rotating shaft 3 can be rotated arbitrarily within the working stroke.
