[0022] The present invention is further described below by way of embodiments, but the present invention is not limited to the scope of the embodiments.

[0023] Example

[0024] like Figure 1-3As shown, this embodiment provides a manual disassembly device for a gearbox. The manual disassembly device includes: a scissor link 1, a screw 2, a rocker 3 and a ball end 4; one end of the scissor link 1 is provided with a ball end 4, and the other end is vertically connected to the screw 2; one end of the screw 2 is provided with a rocker 3; the scissor link 1 moves up and down on the screw 2. In this embodiment, the rocker 3 includes a handle 31 and a support rod 32, the support rod 32 is fixed to the top of the screw 2 through a rotating shaft 33, and the handle 31 is vertically installed at the other end of the support rod 32, so as to facilitate manual rotation of the rocker 3. The screw 2 rotates under the action of the rocker 3 and the rotating shaft 33, and the rocker 3 provides a power source for the rotation of the screw 2.

[0025] like Figure 3-5 As shown, in this embodiment, the scissor link 1 includes two curved links 5, one end of the two curved links 5 is reversely cross-connected, and the other end is opened and installed at the two ends of the screw rod 2. Specifically, the two ends of the curved link 5 are bent in opposite directions, and the cross section is "S" shaped; the scissor link 1 is composed of two curved links 5 of the same shape, one end of the two curved links 5 is cross-connected and flattened, and the curved links 5 are fixed with hinges 7, and the other end is respectively connected to the upper end and the lower end of the screw rod 2, and the screw rod 2 rotates under the action of the rocker 3 to drive the two curved links 5 to move up and down.

[0026] like Figure 3-6 As shown, in this embodiment, two bent connecting rods 5 are connected to the screw rod 2 through a spiral trapezoidal nut 6; the upper end of the screw rod 2 is provided with a positive thread, and the lower end is provided with a reverse thread. Specifically, the two bent connecting rods 5 are fixed to the two spiral trapezoidal nuts 6 by screws, respectively, the bent connecting rod 5 in the upper part is fixed to the left-handed trapezoidal nut 8, and the bent connecting rod 5 in the lower part is fixed to the right-handed trapezoidal nut 9. The left-handed trapezoidal nut 8 is screwed on the positive thread at the upper end of the screw rod 2. When the screw rod 2 rotates under the action of the rocker 3, the bent connecting rod 5 in the upper part moves downward along the screw rod 2 under the action of the left-handed trapezoidal nut 8 and the positive thread. Similarly, the right-handed trapezoidal nut 9 is screwed on the reverse thread at the lower end of the screw rod 2. When the screw rod 2 rotates under the action of the rocker 3, the bent connecting rod 5 in the lower part moves upward along the screw rod 2 under the action of the right-handed trapezoidal nut 9 and the reverse thread. This drives the ball end 4 at the front end of the scissor link 1 to expand, thereby achieving the purpose of disassembling the gear box and the housing.

[0027] In this embodiment, a hand-held handle 10 is also installed in the middle of the screw rod 2. The hand-held handle 10 is used to provide a grip for the operator to use the manual disassembly device. The hand-held handle 10 is installed in the middle of the screw rod 2 and will not affect the movement of the bent links 5 at both ends of the scissor link 1 to the middle to drive the ball end 4 to expand.

[0028] The present embodiment provides a manual disassembly device for a gearbox. A scissor link is designed to connect a screw rod to form a manual disassembly device, positive and negative threads are designed at the upper and lower ends of the screw rod, and the open end of the scissor link is connected by a screw trapezoidal nut. A rocker is installed at the top of the screw rod, and the screw rod is rotated to rotate the rocker, which drives the open ends of the scissor link to move toward the middle respectively. The lever principle is used to increase the force so that the ball head end stuck in the gap between the gearbox and the housing expands, thereby achieving the purpose of disassembling the gearbox. The manual disassembly device of the utility model is easy to operate manually, saves time and effort, is easy to operate, will not damage the gearbox and the housing, improves assembly efficiency, and reduces production costs.

[0029] The working principle of the utility model is: the ball head end 4 is placed in the process gap between the gear box and the shell, the rocker 3 is rotated to rotate the screw rod 2, and the two opened ends of the scissor connecting rod 1 are driven to move toward the middle on the screw rod 2 under the action of the positive and negative threads of the screw rod 2 and the left and right rotating trapezoidal nut. The disassembly force is increased according to the lever principle, so that the ball head end 4 at the front end of the scissor connecting rod 1 expands, thereby separating the gear box and the shell, and achieving the purpose of disassembling the gear box.
