A fixing groove is opened in the middle of the fixed side plate, and the fixed side plate and the connecting vertical plate slide together to drive the movable pressure block to move downward.

[0017] As a preferred embodiment of this utility model, a fixing rod is fixedly connected to the side of the connecting vertical plate, and a fixing cap for locking and limiting is threaded onto the outer surface of the fixing rod, and the fixing cap is engaged in the fixing groove.

[0018] Using the above technical solution, a fixing rod is fixedly connected to the side of the connecting vertical plate, and a fixing cap for locking and limiting is threaded on the outer surface of the fixing rod. The fixing cap is engaged in the fixing groove, which facilitates limiting the movement between the fixing side plate and the connecting vertical plate.

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] Please see Figures 1-8 .

[0038] To address the cumbersome and inconvenient process of fixing the peristaltic pump tube 2 in existing technologies, which hinders quick positioning and disassembly / replacement, this solution employs the following technical approach: a detachable, wear-resistant plastic peristaltic pump tube fixing structure. This structure includes a pump tube fixing sleeve 1 and a peristaltic pump tube 2 that penetrates the middle of the sleeve 1. A movable connecting block 3 is telescopically connected to the left and right sides of the fixing sleeve 1. A movable mounting plate 4 is fixedly connected to the side of the movable connecting block 3 closest to the peristaltic pump tube 2. The movable mounting plate 4 and the arc-shaped clamping plate 5 form a telescopic structure. The arc-shaped clamping plate 5 clamps the left and right sides of the peristaltic pump tube 2. A silicone soft strip 6 is provided on the inner side of the arc-shaped clamping plate 5, and the silicone soft strip 6 is fitted to the peristaltic pump tube 2. A movable pressure block 14 is fitted to the upper end of the movable connecting block 3, and the side of the movable pressure block 14 matches the side of the movable connecting block 3.

[0039] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 7 As shown, during installation, the peristaltic pump tube 2 is first inserted into the pump tube fixing sleeve 1. Arc-shaped clamps 5 are provided at both ends of the inner side of the pump tube fixing sleeve 1. When clamping the peristaltic pump tube 2, the connecting vertical plate 9 is moved downwards, sliding within the fixed side plate 10. A movable pressure block 14 is fixedly connected to the lower end of the connecting vertical plate 9, and the side of the movable pressure block 14 matches the side of the movable connecting block 3. The movable pressure block 14 presses against the movable connecting block 3, thereby causing the movable connecting block 3 to slide between it and the pump tube fixing sleeve 1. Simultaneously, connecting side plates 15 are fixedly connected to both the front and rear ends of the movable connecting block 3. The connecting side plates 15 cause the connecting side rod 16 to slide between it and the limiting post 17, and the connecting side rod 16 presses against the second spring 18. This causes the second spring 18 to undergo elastic deformation, improving the stability of the movable connecting block 3 during movement. At the same time, the movable connecting block 3 pushes the arc-shaped clamping plate 5 to move closer to the peristaltic pump tube 2, so that the arc-shaped clamping plate 5 stably clamps and fixes the peristaltic pump tube 2. Moreover, silicone soft strips 6 are evenly spaced on the inner side of the arc-shaped clamping plate 5, and the silicone soft strips 6 are fitted to the peristaltic pump tube 2. The movable connecting block 3 drives the movable mounting plate 4 to slide between the fixed connecting block 7, and the movable mounting plate 4 and the arc-shaped clamping plate 5 move relative to each other. At the same time, the first spring 8 is provided between the movable mounting plate 4 and the arc-shaped clamping plate 5, which can play a good buffering role for the arc-shaped clamping plate 5, so that the arc-shaped clamping plate 5 forms an elastic structure on the inner side of the pump tube fixing sleeve 1, which can ensure the clamping stability while avoiding damage to the peristaltic pump tube 2.

[0040] In addition, as the connecting vertical plate 9 moves downwards, such as Figure 6 and Figure 8 As shown, a fixing groove 11 is fixedly connected to the side of the connecting vertical plate 9. The connecting vertical plate 9 drives the fixing rod 12 to move downward and connect with the fixing side plate 10 through a slot. Then, the threaded connection is rotated to the fixing cap 13 used for locking and limiting, so that the fixing cap 13 is engaged in the fixing groove 11 opened in the middle of the fixing side plate 10, limiting the connection between the connecting vertical plate 9 and the fixing side plate 10, realizing the fixation between the movable connecting block 3 and the pump tube fixing sleeve 1, and completing the stable clamping of the peristaltic pump tube 2. When it is necessary to adjust the peristaltic pump... To disassemble tube 2, simply reverse the above operation, i.e., loosen the limit between the connecting vertical plate 9 and the fixed side plate 10. At this time, the second spring 18 restores its elastic deformation, pushing the connecting side rod 16 to move outward. The connecting side rod 16, together with the connecting side plate 15, causes the movable connecting block 3 to slide between the movable connecting block 3 and the pump tube fixing sleeve 1, so that the movable connecting block 3 drives the arc-shaped clamp 5 to move away from the peristaltic pump tube 2, loosening the clamp on the peristaltic pump tube 2, thus facilitating the replacement of the peristaltic pump tube 2.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
