Description

Technical Field

[0001] The utility model relates to the technical field of peristaltic pumps, and more specifically, to a peristaltic pump with convenient tube replacement. Background Technique

[0002] During the application of a peristaltic pump, conventional built-in tubes are all attached to the base. Through the rotation of the wheel set, during the rotation process, the rollers on the wheel set repeatedly squeeze the built-in tube, causing the built-in tube to continuously open, close, and generate negative pressure to achieve fluid transmission.

[0003] Since the built-in tube is a wearing part, it needs to be replaced regularly. When replacing the built-in tube in a conventional U-shaped structure, because the surface where the built-in tube is attached to the base is fixed, the pump cover and the wheel set need to be removed simultaneously before installing the built-in tube. When replacing the built-in tube in batches, the workload of tube replacement will be greatly increased, and the batch consistency after tube replacement cannot be guaranteed. Therefore, we made improvements and proposed a peristaltic pump with convenient tube replacement. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide a peristaltic pump with convenient tube replacement, which can effectively solve the problem that the existing traditional U-shaped structure needs to disassemble at least two or more parts, resulting in cumbersome replacement.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A peristaltic pump with convenient tube replacement, including a base, a motor is fixedly installed at the bottom of the base through a cross-recessed pan head screw, a pump cover is installed at the upper end of the base, a hose is arranged between the base and the pump cover, pipe clamps are fixedly installed at both ends of the hose, a boss is installed on one side of the upper surface of the base, and the pipe clamp is inserted into the boss;

[0007] A buckle is rotatably installed in the middle of the boss, a limit card slot is opened on the upper surface of the pump cover, and the upper end of the buckle is matched with the limit card slot.

[0008] Preferably, a wheel frame is fixedly installed at the output end of the motor, several small shafts are rotatably installed inside the wheel frame, a roller is fixedly installed on the shaft body of each small shaft, and a bearing is arranged at the upper end of the wheel frame;

[0009] An upper support is fixedly installed on one side of the base, and the upper support is rotatably connected with the bearing.

[0010] Preferably, joints are installed at both ends of the hose, and a cable tie is arranged on the hose body.

[0011] Preferably, a block is installed at the bottom of the other end of the pump cover, a clamping seat is fixedly installed at the other end of the base, and the block is in limit cooperation with the clamping seat.

[0012] Preferably, positioning posts are respectively arranged on both sides of the bottom of the buckle, and angular limits are arranged on both sides of the buckle.

[0013] Preferably, a guiding groove is formed in the middle of the boss, the inner wall of the guiding groove is in limit fit with the angular limit, a positioning hole is formed in the lower side of the guiding groove, and the positioning post is rotatably installed inside the positioning hole.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] (1) When replacing the built-in tube, only one component needs to be disassembled to replace the built-in tube. Compared with the traditional U-shaped structure that requires at least two or more parts to be disassembled to replace the built-in tube, in this application, only the buckle needs to be opened and the pump cover disassembled to quickly take out the built-in tube, and during assembly, only the pump cover needs to be covered and the buckle closed, so that the replacement efficiency is improved, and under the above conditions, this structure is more compact.

[0016] (2) In this application, the installation and fixation method of the built-in tube is compatible with both fixed-length and non-fixed-length built-in tubes. The end of the fixed-length hose is provided with a joint for extended connection. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation mode

[0025] Next, in combination with the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than 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 work shall fall within the protection scope of the present utility model.

[0026] As Figures 1 to 7 shown, a peristaltic pump with convenient tube replacement includes a base 2. The bottom of the base 2 is fixedly installed with a motor 8 through a cross recessed pan head screw 13. A pump cover 1 is installed at the upper end of the base 2. A hose 9 is arranged between the base 2 and the pump cover 1. Both ends of the hose 9 are fixedly installed with pipe clamps 11. A boss 204 is installed on one side of the upper surface of the base 2. The pipe clamp 11 is inserted into the boss 204;

[0027] A buckle 5 is rotatably installed in the middle of the boss 204. A limit card slot 102 is opened on the upper surface of the pump cover 1. The upper end of the buckle 5 is matched with the limit card slot 102.

[0028] In this embodiment, a wheel frame 3 is fixedly installed at the output end of the motor 8. A plurality of small shafts 7 are rotatably installed inside the wheel frame 3. A roller 6 is fixedly installed on the shaft body of each small shaft 7. A bearing 14 is arranged at the upper end of the wheel frame 3;

[0029] An upper support 4 is fixedly installed on one side of the base 2. The upper support 4 is rotatably connected to the bearing 14.

[0030] In this embodiment, joints 10 are installed at both ends of the hose 9. A cable tie 12 is arranged on the body of the hose 9.

[0031] In this embodiment, a block 101 is installed at the bottom of the other end of the pump cover 1. A card seat 203 is fixedly installed at the other end of the base 2. The block 101 is in limit fit with the card seat 203.

[0032] In this embodiment, positioning columns 502 are respectively arranged on both sides of the bottom of the buckle 5. Angle limits 501 are arranged on both sides of the buckle 5. A guide groove 201 is opened in the middle of the boss 204. The inner wall of the guide groove 201 is in limit fit with the angle limit 501. A positioning hole 202 is opened on the lower side of the guide groove 201. The positioning column 502 is rotatably installed inside the positioning hole 202.

[0033] Through the limit fit between the inner wall of the guide groove 201 and the angle limit 501; at the same time, the buckle 5 is designed with a rotation angle limit to prevent the buckle from rotating too large an angle. The positioning column 502 arranged at the bottom of the buckle 5 can be used to make the buckle 5 rotate between the positioning holes 202, so that the upper end of the buckle 5 can be buckled on the pump cover 1.

[0034] In this application, the mating surface of the combined built-in tube and the pump cover has a specific arc surface design, so that the mating surface of the combined built-in tube and the pump cover is always centered and mated during the operation of the pump. If the combined built-in tube cannot be fully centered and mated with the arc surface, the service life of the built-in tube ≤ 50 hours, and the standard service life of the built-in tube ≥ 1000 hours; and there is an anti-fooling structure design between the pump cover 1 and the base 2 to ensure the uniqueness of the assembly method when the pump cover 1 and the base 2 are assembled.

[0035] In this application, only the buckle 5 needs to be opened, and then the pump cover 1 can be easily taken out, so that the built-in tube can be quickly taken out and replaced with a new built-in tube. Other components do not need to be disassembled by personnel, and the replacement efficiency is improved.
