Description

Technical Field

[0001] The utility model relates to the technical field of gas booster pumps, in particular to a multi-cylinder multi-stage gas booster pump. Background Art

[0002] A gas booster pump is a device used to compress gas. It mainly uses low-pressure gas at the large-area piston end to drive the small-area piston end, thereby generating high-pressure fluid. It can be used to compress air and various other gases. The output air pressure can be steplessly adjusted by the driving air pressure to increase the output air pressure.

[0003] The patent application number is "219865429U" for "a multi-stage multi-cylinder gas booster pump". The booster pump drives the eccentric shaft to rotate by a motor-driven conveyor belt. Due to the eccentric design of the eccentric shaft, the connecting part can achieve a cylindrical motion trajectory. Because the other end of the connecting part cooperates with the rotation of the piston rod, a dynamic effect of a swing arm is formed, which in turn drives multiple piston rods to reciprocate. Through the symmetrical layout between the multiple piston rods, the balance can be well guaranteed, and rapid pressurization can be achieved in a small space. The pressurization effect is also extremely stable.

[0004] However, the applicant believes that the booster pump has the following problems when in use: the booster pump uses a motor to drive the eccentric shaft to rotate, thereby driving the reciprocating motion of the piston, but because the connecting part has a cylindrical motion trajectory rather than linear motion, the movement process of the piston may be unstable, and the multiple piston rods of the booster pump cannot move synchronously. Utility Model Content

[0005] The purpose of the utility model is to provide a multi-cylinder multi-stage gas booster pump, which solves the problem that the movement process of the piston of the existing booster pump is unstable and the multiple piston rods of the booster pump cannot move synchronously.

[0006] To achieve the above object, a multi-cylinder multi-stage gas booster pump is provided, comprising: a base, a cylinder head fixedly connected to the top of the base, a piston sleeve provided on one side of the cylinder head, a piston rod slidably connected to the interior of the piston sleeve to facilitate the boosting of the booster pump;

[0007] The top of the base is fixedly connected to a support leg, the top of the support leg is fixedly connected to a moving slot, the other end of the piston rod is fixedly connected to a moving block, the top of the moving block is fixedly connected to a first mounting plate, the inner side of the first mounting plate is fixedly connected to a first fixed shaft, the top of the base is fixedly connected to an electric lifting rod, the output end of the electric lifting rod is fixedly connected to a mounting seat, the side of the mounting seat is fixedly connected to a second mounting plate, the inner side of the second mounting plate is fixedly connected to a second fixed shaft, and the outer wall of the second fixed shaft is rotatably connected to a connecting rod, so as to drive the synchronous reciprocating motion of multiple piston rods in the corresponding piston sleeves, so that the movement process of the piston rod is more stable.

[0008] According to the multi-cylinder multi-stage gas booster pump, through holes are provided at both ends of the connecting rod, and the shape and size of the through holes match the shape and size of the first fixed shaft and the second fixed shaft, and the two ends of the connecting rod are respectively rotatably connected to the first fixed shaft and the second fixed shaft, which facilitates the connection between the connecting rod and the first fixed shaft and the second fixed shaft.

[0009] According to the multi-cylinder multi-stage gas booster pump, the shape and size of the moving block match the shape and size of the moving groove, and the moving block is slidingly connected to the moving groove under the action of the connecting rod, which facilitates the sliding of the moving block inside the moving groove.

[0010] According to the multi-cylinder multi-stage gas booster pump, sliders are fixedly connected on both sides of the moving block, and sliding grooves are opened on both sides of the moving groove. The shape and size of the sliders match the shape and size of the sliding grooves, and the sliders are slidably connected to the sliding grooves, which facilitates the sliding of the sliders and improves the stability of the moving block in the moving groove.

[0011] According to the multi-cylinder multi-stage gas booster pump, both sides of the cylinder cover are provided with an air inlet and an air outlet, which facilitates the boosting of the booster pump.

[0012] According to the multi-cylinder multi-stage gas booster pump, the number and positions of the cylinder cover, piston rod, movable groove, movable block, first fixed shaft, second fixed shaft and connecting rod correspond to each other, so as to facilitate the synchronous reciprocating motion of multiple piston rods.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: the multi-cylinder multi-stage gas booster pump drives the lifting and lowering of the mounting seat through the provided electric lifting rod, thereby driving the connecting rod to push the moving block to move in the moving groove. Since one side of the moving block is fixedly connected to the piston rod, the lifting and lowering of the electric lifting rod can drive multiple piston rods to reciprocate at the same time, thereby improving the boosting efficiency of the booster pump and the stability of the boosting process, and at the same time improving the practicality of the multi-cylinder multi-stage gas booster pump to a certain extent.
