Technical Field
[0001] This utility model relates to the field of peristaltic pump technology, and more specifically, to a peristaltic pump that prevents the adapter from falling off. Background Technology
[0002] Peristaltic pumps pump fluid by alternately squeezing and releasing a tubing through rotating rollers. The pump tubing between three rotating rollers forms a "pillow" shape for the fluid. Currently, peristaltic pumps use a motor to drive an I-beam joint, where rollers directly squeeze the tubing to create a sealed vacuum environment and draw in the liquid. However, existing adapters are prone to detachment and cannot be securely fixed inside the pump.
[0003] Therefore, how to improve the adapter so that it can be fixed inside the pump has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention
[0004] The technical problem to be solved by this utility model is that, in the existing technology, the rotating shaft of the motor drives the I-beam groove, and the roller on the I-beam groove directly squeezes the hose to form a sealed vacuum environment to pump liquid. The existing adapter is easy to fall off and cannot be fixed in the pump. This utility model provides a peristaltic pump that prevents the adapter from falling off.
[0005] The technical solution adopted by this utility model to solve its technical problem is: to construct a peristaltic pump that prevents the adapter from falling off, which has the following features:
[0006] The pump bottom shell is formed into a hollow structure. A through hole is provided on one side of the pump bottom shell, and a semi-circular groove is provided at one end of the pump bottom shell. Ribs are provided in the groove. The shell is provided with a buckle structure to cooperate with the pump top cover for installation and fixation. Two buckle structures are provided at the bottom to fix the motor.
[0007] The motor has a shaft that passes through the through hole and extends into the pump bottom housing, and a cross-shaped shaft is provided on one side of the motor.
[0008] An I-beam groove is radially disposed within the pump bottom housing. The I-beam groove meshes with the cross-shaped rotating shaft. Equilateral triangles are arranged through holes on the top and bottom surfaces of the I-beam groove.
[0009] A steel needle is inserted into the through hole of the I-shaped groove;
[0010] The roller is cylindrical with a through hole in the middle to facilitate the passage of the steel needle and its installation in the I-shaped groove.
[0011] A flexible hose, which is fitted onto a roller inside the I-shaped groove;
[0012] The pump cover has a semi-circular groove at one end, with ribs in the groove. The pump cover covers the top of the pump base and is used to fix the adapter and hose.
[0013] The adapter is L-shaped and has a circular baffle at one end. The circular baffle is located in the semi-circular groove between the pump bottom shell and the pump top cover.
[0014] In the peristaltic pump with anti-adaptor detachment described in this utility model, a through hole is provided on one side of the pump base, through which the motor passes and extends into the base; one end of the I-beam groove is connected to the cross shaft of the motor, the I-beam groove is radially arranged inside the pump base, a steel needle passes through the I-beam groove, a roller passes through the steel needle, and a hose is sleeved on the roller of the I-beam groove; one end of the adapter is connected to a hose and installed between the pump base and the pump top cover, and the adapter is restricted by the ribs at the semi-circular grooves in the pump base and the pump top cover; the roller squeezes the hose to form a sealed vacuum pumping environment.
[0015] Compared with existing technologies, the adapter is restricted to move horizontally along the pipe opening by the ribs at the semi-circular grooves in the pump bottom shell and the pump top cover. At the same time, a circular baffle is designed on the adapter. It is installed by the cooperation of the ribs at the semi-circular grooves in the pump bottom shell and the pump top cover to prevent the adapter from falling off when the pump is working. In addition, the circular baffle does not restrict the adapter to rotate 360 degrees along the pipe opening, so it can be used for different angle requirements. Attached Figure Description

A semi-circular groove is provided at one end of the pump bottom shell 102. Ribs are provided in the groove. The shell is provided with a buckle structure to cooperate with the pump top cover for installation and fixation. Two buckle structures are provided at the bottom to fix the motor.
[0022] The motor 101 has a rotating shaft that passes through the through hole and extends into the pump bottom housing. A cross-shaped rotating shaft is provided on one side of the motor 101.
[0023] The I-beam groove 107 is radially disposed inside the pump bottom shell 102. The I-beam groove 107 meshes with the cross-shaped rotating shaft. Equilateral triangles are arranged through holes on the top and bottom surfaces of the I-beam groove 107.
[0024] Steel needles 106 (106a, 106b, 106c) are inserted into the through holes of the I-beam groove;
[0025] The rollers 105 (105a, 105b, 105c) are cylindrical with a through hole in the middle, so that the steel needles 106 (106a, 106b, 106c) can pass through and be installed in the I-beam groove 107.
[0026] The flexible hose 103 is sleeved on the rollers 105 (105a, 105b, 105c) inside the I-shaped groove 107;
[0027] The pump cover 108 has a semi-circular groove at one end, and ribs are provided in the groove. The pump cover 108 covers the top of the pump bottom shell 102 and is used to fix the adapter 104 (104a, 104b) and the hose 103.

At the same time, a circular baffle is designed on the adapter. It is installed by cooperating with the ribs at the semi-circular grooves inside the pump base and pump cover to prevent the adapter from falling off when the pump is working. Meanwhile, the circular baffle does not restrict the adapter from rotating 360 degrees along the pipe opening, which can be used for different angle requirements.
