Description

Novel pump body structure Technical Field The utility model belongs to the technical field of pump bodies, and particularly relates to a novel pump body structure. Background The structural connection of the existing pump body is formed by three claw buckles uniformly distributed in the circumference. The structure is simple, complex processes like screw fixation and the like are omitted, and the production cost is reduced. However, the claw buckle has the following defects that the strength and the action strength of the claw buckle are ensured, the positioning boss of the claw buckle must reach a certain width, the thickness of the claw buckle is also thick, and the positioning step fixedly connected with the claw buckle also has a certain height, so that the connection stability of the claw buckle must be ensured by reaching the relevant strength. In order to meet the above requirements, the three claw buckles are buckled into the grooves of the fixed positioning steps, so that the claw buckles have to generate a certain deformation amount, and the claw buckles can be buckled into the fixed positions only when the deformation amount reaches the condition that the claw buckles are completely retracted into the grooves of the positioning steps. In addition, the moving structure is realized by a push-pull structure formed by connecting a reset pressure spring and the tail part of the movable iron core. This arrangement resets the compression spring in a compressed state. The fixed iron core and the fixed mode on the fixed iron core are also a movable structure. Therefore, the iron core is in a non-central shaft state under the action of the reset pressure spring, and has a certain inclination. The stress is just at the inclined position of the tail end of the iron core. The acting force range of the return spring comprises the whole space of the iron core and the return spring. In this state, the movable iron core generates a large polarization due to the eccentric force of the return spring during the up-and-down reciprocation of the movable iron core. The friction between the iron core and the inner wall of the cylindrical pipe is larger, so that a great amount of pump body power loss is increased. Thus, the flow stability of the pump body is not facilitated, and the attenuation is larger. Therefore, the utility model designs a novel pump body structure.
