Description

Technical Field

[0001] This utility model relates to the field of gasoline engine water pumps, and more particularly to a gasoline engine water pump with a shock absorption mechanism. Background Technology

[0002] A gasoline engine water pump is a centrifugal pump, consisting of a pump and a support frame. It is low-cost, lightweight, and easy to maintain, and also has advantages such as low manufacturing cost and low noise. The common gasoline engine water pump is a centrifugal pump. The working principle of a centrifugal pump is that when the pump is filled with water, the engine drives the impeller to rotate, generating centrifugal force. Under the action of centrifugal force, the water in the impeller channels is thrown outwards and flows into the pump casing. This reduces the pressure at the center of the impeller, which is lower than the pressure in the inlet pipe. Water then flows from the suction pool into the impeller under this pressure difference. In this way, the pump can continuously draw and supply water.

[0003] A gasoline engine water pump generates power by burning gasoline, driving the pump impeller to rotate and pump water. During this process, the ignition, combustion, and explosion of the gasoline engine, as well as the rotation of the water pump impeller, all produce vibrations. These vibrations are inevitable phenomena in the process of mechanical energy conversion and transmission. Furthermore, the gasoline engine water pump consists of multiple mechanical components, such as the crankshaft, connecting rod, piston, and water pump impeller. When these components move at high speeds, they generate additional vibrations due to inertia, friction, and mechanical clearances. These vibrations are transmitted to the outside through the water pump's base, pipes, and other components, creating perceptible vibrations.

[0004] Prolonged vibration can not only affect the service life and performance of water pumps, leading to accelerated wear of components and reduced sealing performance, but also cause noise pollution to the surrounding environment.

[0005] Therefore, it is necessary to provide a new gasoline engine water pump with a shock-absorbing mechanism to solve the above-mentioned technical problems. Utility Model Content

One end of the driving rack is hinged to the hinge plate, and a first buffer is fixed to the other end of the driving rack. The end of the first buffer is fixed to the base plate. The gear is rotatably connected to the base plate and meshes with the driving rack and the driven rack. A second buffer is fixed to the end of the driven rack, and the end of the second buffer is fixed to the base plate.

[0011] Preferably, each of the two driven racks arranged opposite to each other is provided with a second movable groove, and a second movable hole is provided on the bottom wall of the second movable groove. The two driven racks opposite to each other are supported by a second support member.

[0012] Preferably, the second support member includes a second support rod and two second upright plates, the two second upright plates are respectively inserted into two second movable holes, the second support rod movably passes through the through holes opened in the inner walls of the two second movable slots, and the two ends of the second support rod are respectively fixed to the two second upright plates.

[0013] Preferably, at least one auxiliary buffer is installed between the bottom plate and the top plate. The auxiliary buffer includes a movable plate, a sleeve, and a third buffer. The top end of the movable plate is fixed to the bottom of the top plate, the bottom end of the sleeve is fixed to the top of the bottom plate, the bottom end of the movable plate is slidably disposed inside the sleeve, and the two ends of the third buffer are respectively fixed to the bottom end of the movable plate and the bottom wall of the inner cavity of the sleeve.

[0015] Preferably, in a stable state, the angle between the hinge plate and the horizontal plane of the gasoline engine water pump body is 30-60 degrees.

[0016] Compared with related technologies, the gasoline engine water pump with a shock-absorbing mechanism provided by this utility model has the following beneficial effects:

[0017] When the gasoline engine water pump body vibrates during operation, the gasoline engine water pump body drives the top plate to move downward, reducing the angle between the hinge plate and the horizontal plate. Under the push of the hinge plate, the drive gear squeezes the first buffer member. At the same time, the drive rack drives the gear to rotate. Under the action of the gear, the driven rack moves in the opposite direction to the drive rack, stretching the second buffer member. Under the action of the first and second buffer members, the buffering effect of the gasoline engine water pump body is achieved, reducing the problem of component wear and noise pollution caused by vibration. In this utility model, the mutual cooperation of the drive rack, gear and driven rack enables the device to achieve multi-level buffering in a limited space, improving the buffering effect.
