Description

Technical Field

[0001] This application relates to the field of plunger pumps, and more specifically, to a plunger pump front plate that is easy to install and remove. Background Technology

[0002] Currently, piston pumps are an important component of hydraulic systems. They rely on the reciprocating motion of pistons within a cylinder to change the volume of the sealed working chamber, thereby achieving oil suction and pressure. Piston pumps offer advantages such as high rated pressure, compact structure, high efficiency, and convenient flow rate adjustment. They are widely used in high-pressure, high-flow-rate applications where flow rate regulation is required, such as hydraulic presses, construction machinery, and ships.

[0003] The front plate is used to protect the plunger pump. During assembly, the front plate needs to be fixed to the pump housing. The front plate generally needs to be replaced after a period of use.

[0004] The existing technical solutions mentioned above have the following drawbacks: the front panel structure is simple and easily damaged, and the front panel is mostly a fixed structure, which is cumbersome to disassemble and assemble, complicated to operate, and causes inconvenience to the operator. Utility Model Content

[0005] To overcome the above shortcomings, this application provides a plunger pump front plate that is easy to disassemble and assemble, aiming to improve the problems of cumbersome disassembly and assembly and complicated operation.

[0007] The pump casing sidewall is provided with a positioning groove, and the inner wall of the positioning groove is provided with a slot; the protective structure includes a front plate and a guard plate, a buffer is installed between the front plate and the guard plate, and a reinforcing rib is fixed to the inner wall of the guard plate;

[0008] The snap-fit ​​structure includes a protrusion and a snap-fit ​​block. The protrusion is fixedly connected to the front plate and engages with the positioning groove. The snap-fit ​​block is embedded in the protrusion and engages with the slot. A limit button for limiting the displacement of the snap-fit ​​block is installed inside the protrusion.

[0009] In a preferred embodiment of this utility model, two buffer members are provided, and the two buffer members are symmetrically arranged at both ends of the front plate.

[0010] In a preferred embodiment of this utility model, the front plate is fixed with a limiting tube, the guard plate is fixed with a limiting rod, and one end of the limiting tube is inserted into the limiting rod.

[0011] In a preferred embodiment of this utility model, the buffer includes

[0012] The front plate is fixed with a hinge seat, a pull rod with one end hinged to the hinge seat, and a damping structure with one end hinged to the hinge seat; one end of the pull rod abuts against the inner wall of the guard plate, and the other end of the damping structure is hinged to the pull rod.

[0013] In a preferred embodiment of this utility model, the damping structure includes a slide rod with one end hinged to the pull rod, a slide sleeve with one end hinged to the hinge seat, and a compression spring disposed within the slide sleeve; one end of the slide rod is slidably inserted into the slide sleeve; and one end of the compression spring abuts against the slide rod.

[0014] In a preferred embodiment of the present invention, the upper end of the locking block extends to the outer surface of the protrusion, and a first return spring is connected between the lower end of the locking block and the inner wall of the protrusion.

[0015] In a preferred embodiment of this utility model, a guide rod is fixed inside the protrusion, a through hole is provided on the surface of the locking block, the guide rod slides through the through hole, and the first reset spring is sleeved on the surface of the guide rod.

The limit button is located directly below the card block.

[0017] Beneficial effects: This application provides a plunger pump front plate that is easy to install and disassemble. By pressing the limit button, the locking block moves downward without obstruction, realizing the separation of the locking block from the slot, which is convenient for disassembly. After releasing the button, it resets, resisting the sliding path of the locking block to achieve a locking effect, preventing the protrusion from dislodging from the positioning groove during equipment operation and ensuring the stable connection of the protective structure. A buffer is installed between the front plate and the guard plate to reduce the damage of external impacts to the plunger pump and improve the protection performance. Reinforcing ribs are fixed on the inner wall of the guard plate to enhance the resistance strength, increase the service life, and extend the maintenance and replacement cycle. The protective structure improves the durability of the front plate and extends its service life. The snap-fit ​​structure facilitates disassembly and maintenance, simplifies operation, and improves work efficiency. Attached Figure Description
