AI Technical Summary
When replacing the pump pipe, existing peristaltic pumps need to remove the pump head or use a quick connection structure, which leads to the easy-to-break, loss or damage to the pump cover, and the clamping pressure of the snapping structure on the pump pipe is limited, affecting the friction between the pump pipe and the synchronous disk.
The peristaltic pump with a large flow connecting rod structure drives the pump seat to move during the opening and closing of the pump cover, thereby realizing the replacement of the pump pipe without removing the pump cover. The pump seat and the pump shell match the pump tube to strengthen the binding force of the pump pipe.
It realizes the convenience and safety of pump pipe replacement, avoids damage and loss of pump cover, enhances the friction between the pump pipe and the synchronization disk, and meets the requirements of large flow.

Abstract
Description
Technical Field
[0001] The utility model relates to a peristaltic pump with a large-flow connecting rod structure, belonging to the technical field of peristaltic pumps. Background Art
[0002] During the use of a peristaltic pump, the pump tube, as a vulnerable part, often needs to be replaced. At present, the vast majority of peristaltic pump tubes need to disassemble the pump head for replacement, and a small number are quickly disassembled and replaced through a quick-connection structure. During the quick-disassembly replacement process, the pump cover needs to be disassembled for replacement. In actual applications, situations such as loss or damage of the pump cover caused by disassembly may occur, resulting in affecting the replacement. Moreover, the clamping pressure of the buckle structure on the pump tube is limited, affecting the friction between the pump tube and the synchronous disk. Summary of the Utility Model
[0003] The utility model overcomes the deficiencies existing in the prior art and provides a peristaltic pump with a large-flow connecting rod structure. The pump tube has a large space, meeting the requirements of large flow. During the opening and closing process of the pump cover, the connecting rod structure drives the pump seat to press and release the pump tube, without the need to disassemble the pump cover.
[0004] To solve the above technical problems, the technical solution adopted by the utility model is as follows: A peristaltic pump with a large-flow connecting rod structure, including a machine body, a pump housing, a pump seat, a synchronous disk, and a pump tube. The pump housing is fixed on the machine body. The pump seat is arranged on the pump housing. The synchronous disk is power-connected to the power output end of the machine body passing through the pump housing. The pump tube is arranged on the synchronous disk. The pump seat is movably arranged on the side of the pump housing and can move horizontally along the pump housing. The outer end of the pump seat is connected with a pump cover through a connecting rod. One end of the pump cover is hinged to the connecting rod, and the other end of the pump cover is fixed on a locking block on the machine body. The pump cover can drive the connecting rod to drive the pump seat to move during the opening and closing process.
[0005] Further, a horizontal guide groove is arranged at one end of the pump seat facing the pump housing. The pump seat is fixed through a guide post fixed on the pump housing, and the guide post is inserted into the guide groove in a matching manner.
[0006] Further, the synchronous disk, the pump seat, and the pump housing jointly constrain the pump tube, and the pump tube extends out from the side of the pump housing far from the distal end of the pump seat.
[0007] Further, a groove for installing the connecting rod is arranged at the outer end of the pump seat, and the end of the connecting rod is correspondingly hinged in the groove.
[0008] The beneficial effects of the present utility model compared with the prior art are as follows: The present utility model uses a synchronous disk, a pump base and a pump housing to match and constrain the pump pipe. The pump pipe extends from the side of the pump housing far away from the distal end of the pump base. The constraint space is large, the applicable pump pipe diameter is large, meeting the use requirements of large flow. At the same time, the pump cover is connected to the movably arranged pump base through a connecting rod structure. When the pump cover is opened, the connecting rod drives the pump base to move outwards, loosening the pump pipe. When the pump cover is closed, the connecting rod drives the pump base to move inwards, pressing the pump pipe. The pipe replacement is convenient, and the pump cover is not easily damaged or lost, with strong practicability. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The following further elaborates on the present utility model with reference to specific embodiments.
[0014] As Figure 1 , Figure 2 shown, a peristaltic pump with a large-flow connecting rod structure of the present utility model includes a machine body 1, a pump housing 2, a pump base 3, a synchronous disk 4 and a pump pipe. The pump housing 2 is fixed on the machine body 1. One end of the pump base 3 facing the pump housing 2 is provided with a horizontal guide groove. The pump base 3 is fixed through a guide post fixed to the pump housing 2. The guide post is inserted into the guide groove in a matching manner. The synchronous disk 4 is power-connected to the power output end of the machine body 1 penetrating through the pump housing 2. The pump pipe is arranged on the synchronous disk 4. A groove for installing the connecting rod 5 is provided at the outer end of the pump base 3. The end of the connecting rod 5 is correspondingly hinged in the groove. One end of the pump cover 6 is hinged to the connecting rod 5, and the other end of the pump cover 6 is fixed to a locking block on the machine body 1. The pump cover 6 can drive the connecting rod 5 to drive the pump base 3 to move during the opening and closing process.
[0015] The present utility model uses the synchronous disk 4, the pump base 3 and the pump housing 2 to match and constrain the pump pipe. The pump pipe extends from the side of the pump housing 2 far away from the distal end of the pump base 3. The constraint space is large, the applicable pump pipe diameter is large, meeting the use requirements of large flow. At the same time, the pump cover 6 is connected to the movably arranged pump base 3 through a connecting rod structure. When the pump cover 6 is opened, the connecting rod drives the pump base 3 to move outwards, loosening the pump pipe. When the pump cover 6 is closed, the connecting rod drives the pump base 3 to move inwards, pressing the pump pipe. The pipe replacement is convenient, and the pump cover 6 is not easily damaged or lost, with strong practicability.
