DETAILED DESCRIPTION

[0023] The utility model provides a drainage bag hanging and fixing device, such as Figure 1-3 As shown, it includes a main shaft 11, a hanging handle 12, a rotating disk 13, a first opening 14, a first sliding groove 15, a drainage bag body 16, an upper cover 17, a clamping groove 18, a drainage tube 19, a sliding connecting rod 20, a clamping block 21, a first connecting block 22, an elastic member 23, a rotating groove 24, a rotating ring 25, an internal thread 26, an external thread 27, and a drainage tube holder 28.

[0024] like Figure 1-3 As shown, the upper cover 17 is fixedly connected to the drainage bag body 16, and a drainage tube 19 is arranged on the upper cover 17, which is characterized in that: a snap-in groove 18 is opened on the outer circumferential surface of the upper cover 17, and the suspension mechanism includes a main shaft 11 and a rotating disk 13, one end of the main shaft 11 is rotatably connected to the suspension handle 12, a first opening 14 and three first sliding grooves 15 are opened on the rotating disk 13, the main shaft 11 is rotatably connected to the first opening 14, and a limiting assembly is arranged in the first sliding groove 15, and the limiting assembly includes a sliding connecting rod 20 and a snap-in block 21, the sliding connecting rod 20 is fixedly connected to the snap-in block 21, the sliding connecting rod 20 is slidably connected to the first sliding groove 15, and the snap-in block 21 is used to engage with the snap-in groove 18.

[0025] It is worth noting that a limiting groove is provided in the first sliding groove 15, and a limiting block is provided on the part of the outer cylindrical surface of the sliding link 20 located in the first sliding groove 15, so the relative height of the sliding link 20 and the first sliding groove 15 remains unchanged, and the three first sliding grooves 15 are arranged with equal arcs with the first opening 14 as the axis core. The first sliding groove 15 is an arc-shaped groove, and one end of the first sliding groove 15 is connected to the first opening 14. A drainage tube holder 28 is provided on the outer cylindrical surface of the rotating disk 13, and the drainage tube holder 28 is used to clamp the drainage tube 19.

[0026] The limiting assembly also includes a first connecting block 22, an elastic member 23 and a rotating ring 25. The first connecting block 22 is rotatably connected to one end of the sliding connecting rod 20 away from the clamping block 21. A rotating groove 24 is opened on the main shaft 11. The rotating ring 25 is rotatably connected to the rotating groove 24. One end of the elastic member 23 is fixedly connected to the first connecting block 22, and the other end of the elastic member 23 is fixedly connected to the outer cylindrical surface of the rotating ring 25.

[0027] A chamfer is provided between the end surface of the clamping block 21 away from the sliding link 20 and the outer circumferential surface of the clamping block 21 , and a chamfer is provided between the end surface of the upper cover 17 away from the drainage bag body 16 and the outer circumferential surface of the upper cover 17 .

[0028] An internal thread 26 is provided on the outer circumferential surface of the first opening 14, and an external thread 27 is provided on the outer circumferential surface of the main shaft 11 near the end of the drainage bag body 16, and the internal thread 26 is adapted to the external thread 27. When the sliding link 20 is located at the extreme position of the first sliding groove 15 away from the first opening 14, the elastic member 23 is in a stretched state, and when the sliding link 20 is located at the extreme position of the first sliding groove 15 close to the first opening 14, the elastic member 23 is in a relaxed state.

[0029] When the drainage bag is hung and fixed in this scheme, first, the upper cover 17 is aligned with the lower end of the main shaft 11, and the rotating disk 13 is rotated to move the rotating disk 13 toward the lower end of the main shaft 11. The rotating disk 13 drives the sliding connecting rod 20, and the clamping block 21 drives the clamping block 21 to move until the lower plane of the clamping block 21 contacts the chamfer of the upper plane of the upper cover 17, and then, the rotating disk 13 is continued to be pushed to rotate so that the clamping block 21 moves toward the upper cover 17.

[0030] When the clamping block 21 continues to move downward, the clamping block 21 is subjected to a force away from the chamfered surface of the upper cover 17, and the clamping block 21 drives the sliding link 20 to slide along the first sliding groove 15 in a direction away from the first opening 14. The sliding link 20 drives the first connecting block 22 to stretch the elastic member 23, and the elastic force of the elastic member 23 on the first connecting block 22 and the pulling force generated by the first connecting block 22 on the elastic member 23 are balanced with each other.

[0031] When the clamping block 21 moves to the point where the clamping block 21 is opposite to the clamping groove 18, the pulling force generated by the first connecting block 22 on the elastic member 23 disappears, and the elastic force of the elastic member 23 on the first connecting block 22 drives the first connecting block 22 to move in the direction of the elastic member 23, and the first connecting block 22 drives the sliding connecting rod 20 to slide along the first sliding groove 15 in the direction close to the first opening 14, and the sliding connecting rod 20 drives the clamping block 21 to embed into the clamping groove 18.

[0032] Finally, the drainage tube 19 is embedded in the drainage tube holder 28, and the hanging handle 12 is hung on the hook.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
