[0021] See also Figure 1-4 , the utility model provides the following technical solutions:

[0022] A gear box that is easy to disassemble, assemble and overhaul includes a gear set 3. A front cover 1 and a rear cover 2 are respectively provided on both sides of the gear set 3. The gear set 3 is positioned and installed through the front cover 1 and the rear cover 2. The front cover 1 and the rear cover 2 can cover each other. A sealing rubber ring 5 is respectively installed on the two connecting surfaces of the front cover 1 and the rear cover 2. A plurality of connecting mechanisms 4 are jointly installed on the front cover 1 and the rear cover 2. When the plurality of connecting mechanisms 4 are buckled, the front cover 1 and the rear cover 2 are pressed against each other, and at the same time, the two sealing rubber rings 5 ​​are squeezed against each other, thereby ensuring the sealing of the connection between the front cover 1 and the rear cover 2.

[0023] The connecting mechanism 4 includes a hook 41, and a connecting boss 11 is provided at the connection between the front cover 1 and the rear cover 2, and a connecting boss 21 is correspondingly provided on the rear cover 2. After assembly is completed, the connecting boss 11 and the connecting boss 2 21 are correspondingly fitted with each other, the hook 41 is fixed on the upper side of the connecting boss 2 21, and the hook surface of the hook 41 faces upward, and a connecting end 42 is fixed on the lower side of the connecting boss 11, and a panel 43 is rotatably connected to the connecting end 42, one end of the panel 43 is connected to the connecting end 42, and the other end is a movable end, and a pull ring 44 is rotatably connected to the movable end of the panel 43. When the pull ring 44 is hooked with the hook 41, the front cover 1 and the rear cover 2 are engaged with each other, and the two sealing rubber rings 5 ​​are squeezed against each other, that is, the gear box installation is completed.

[0024] A limit block 47 is provided at the movable end of the panel 43. When the panel 43 is in the buckled state, the limit block 47 contacts the outer wall of the front cover 1, and the panel 43 cannot continue to rotate in the direction of the front cover 1.

[0025] The minimum distance from the rotation center of the pull ring 44 on the panel 43 to the front cover 1 is smaller than the distance from the rotation center of the panel 43 on the connecting end 42 to the front cover 1, that is, when the panel 43 is in the snap-fit ​​state, the pull ring 44 exerts a pulling force on the panel 43 obliquely upward inside the gear box, and this pulling force and the supporting force of the limit block 47 on the panel 43 offset each other, thereby preventing the panel 43 from moving and maintaining the locking state of the connecting mechanism 4, thereby ensuring the stability of the connection.

[0026] A slot 45 is provided on the plate surface of the movable end of the panel 43, and a buckle 46 is correspondingly provided on the outer side wall of the front cover 1. The end of the buckle 46 connected to the front cover 1 is made of elastic metal, and the end of the buckle 46 away from the front cover 1 is set in a hook shape, and the hook tip of the buckle 46 can pass through the slot 45. The hook tip of the buckle 46 faces the side away from the rear cover 2 and can be engaged with the slot 45. When the panel 43 is buckled downward, the hook tip of the buckle 46 contacts the bottom edge of the slot 45, and the bottom edge of the slot 45 pushes the buckle 46 to bend upward by a certain angle until the hook tip of the buckle 46 passes through the slot 45, and the buckle 46 is reset and engaged with the slot 45. The buckle 46 enhances the stability of the panel 43 buckling, thereby improving the bonding performance of the connecting surface of the front cover 1 and the rear cover 2.

[0027] When the gear box needs to be disassembled, it is only necessary to push the buckle 46 upwards and rotate the panel 43 outwards so that the buckle 46 is disengaged from the slot 45 and the pull ring 44 is disengaged from the hook 41, which is convenient to operate.

[0028] Specifically, the front cover 1 and the rear cover 2 are snap-connected through a number of connecting mechanisms 4. By rotating the panel 43 of the connecting mechanism 4 upward, the pull ring 44 can be moved into the hook 41, and then the panel 43 is rotated downward until the limit block 47 abuts against the outer wall of the front cover 1. At this time, the pull ring 44 pulls the hook 41 downward so that the front cover 1 and the rear cover 2 fit tightly against each other. At the same time, the upward reaction force of the pull ring 44 on the panel 43 and the supporting force of the front cover 1 on the panel 43 through the limit block 47 are balanced with each other. The connecting mechanism 4 is in a locked state, which is easier to disassemble and assemble than with bolt connections, and is convenient for maintenance.
