[0020] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0021] This embodiment provides a quick disassembly and assembly gear shifting structure, such as Figure 1 and Figure 2 As shown, it comprises a shifting tooth 1, a shifting tooth buckle 2, a shifting tooth mounting shaft 3, a shifting tooth cover plate 7 and a spring 6. The shifting tooth mounting shaft 3 is arranged at the inner sides of both ends of the shifting tooth 1. The shifting tooth mounting shaft 3 is provided with a clamping groove 31. The shifting tooth 1 is provided with the shifting tooth buckle 2 on the inner side corresponding to the shifting tooth mounting shaft 3. The shifting tooth buckle 2 is provided with a boss 211. The shifting tooth cover plate 7 is arranged at the rear side of the shifting tooth 1. The spring 6 is arranged between the shifting tooth buckle 2 and the shifting tooth cover plate 7. Under the action of the spring 6, the boss 211 is clamped with the clamping groove 31. The shifting tooth buckle 2 clamps the boss 211 on the shifting tooth buckle 2 to the clamping groove 31 of the shifting tooth mounting shaft 3 by the elastic force of the spring 6. When the shifting tooth buckle 2 is pressed, the spring 6 is compressed, and the boss 211 on the shifting tooth buckle 2 is separated from the clamping groove 31 of the shifting tooth mounting shaft 3. At this time, the shifting tooth 1 can be disassembled by moving it upward.

[0022] The structure of this embodiment is suitable for the gear shifting 1 structure used when the synchronous belt 5 transports capsules. The structure adopts the buckle principle to achieve the rapid disassembly and assembly of the gear shifting 1 without tools, thus overcoming the difficulty of the traditional gear shifting 1 being difficult to disassemble and assemble.

[0023] Specifically, a synchronous belt holder 4 is provided below the shifting gear 1 corresponding to the shifting gear installation shaft 3, and the synchronous belt holder 4 is provided above the synchronous belt 5. The shifting gear 1 is installed on the synchronous belt 5 through the shifting gear installation shaft 3 and the synchronous belt holder 4.

[0024] Furthermore, the shift gear mounting shaft 3, the synchronous belt holder 4 and the synchronous belt 5 are connected by screws.

[0025] Specifically, the slot 31 is a circumferential annular groove arranged on the gear mounting shaft 3. In addition, the slot 31 may not be a full-circle structure, but may be a partial groove in the circumferential direction, as long as the boss 211 can enter the slot 31.

[0026] Specifically, the shifting gear buckle 2 includes a front shaft 21 and a rear shaft 22 connected in sequence, the diameter of the rear shaft 22 is smaller than the diameter of the front shaft 21, the front shaft 21 passes through the shifting gear 1, the boss 211 is arranged on the front shaft 21, the shifting gear cover plate 7 is provided with a groove corresponding to the rear shaft 22, the rear shaft 22 extends into the groove, and the spring 6 is sleeved on the rear shaft 22. The present application does not impose any specific restrictions on the shape of the boss 211, as long as the boss 211 can enter the slot 31. The rear side surface of the shifting gear 1 is provided with a mounting cavity corresponding to the boss 211 and the slot 31, and the boss 211 and the slot 31 are engaged in the mounting cavity. A horizontal circular hole for mounting the front shaft 21 is provided on the front side surface of the shifting gear 1, and the circular hole passes through the mounting cavity backwards and is connected with it.

[0027] Specifically, mounting holes are provided at both ends of the shifting tooth 1 and penetrated vertically, and the shifting tooth mounting shaft 3 is arranged in the mounting holes. The positions of the mounting holes enable the clamping slot 31 to be located in the mounting cavity.

[0028] The working process of this embodiment is as follows: there is a circle of annular grooves on the shift gear installation shaft 3 as a slot 31, and there is a boss 211 on the shift gear buckle 2. The shift gear buckle 2 clamps the boss 211 on the shift gear buckle 2 to the slot 31 of the shift gear installation shaft 3 through the elastic force of the spring 6; when the shift gear buckle 2 is pressed, the spring 6 is compressed, and at the same time the boss 211 on the shift gear buckle 2 is disengaged from the slot 31 of the shift gear installation shaft 3, and the shift gear 1 can be removed by moving it upwards; the operation process during installation is opposite to the above.

[0029] Installation process of the shift gear 1 and the shift gear buckle 2: the synchronous belt holder 4 and the shift gear mounting shaft 3 are installed on the synchronous belt 5 by screws; the shift gear buckle 2 is installed on the shift gear 1, and the spring 6 is installed on the shift gear buckle 2 and fixed by the shift gear cover plate 7.

[0030] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
