Screw-free inflating pump movement

Abstract

The invention relates to the technical field of portable air compressors, in particular to a screw-free inflating pump movement. The screw-free inflating pump movement comprises a cylinder piston assembly, a driving motor and a speed reduction assembly and further comprises an inner box cover and an outer box cover which are buckled to each other; a containing cavity is formed in the inner box cover and the outer box cover which are buckled; the cylinder piston assembly and the speed reduction assembly are both installed in the containing cavity; the driving motor is connected to the inner box cover in a clamped manner and connected with the speed reduction assembly; a piston connection rod of the cylinder piston assembly is connected with the speed reduction assembly; and a cylinder cover is connected to an air outlet of the cylinder piston assembly in a clamped manner. By means of the inflating movement, various parts can be connected and fixed without screws, the installing procedures of the inflating movement are simplified, it is not needed to allocate lots of workers to perform the screw locking action in the batch production process, installation is convenient and fast, the labor intensity of workers is relieved, and the manufacturing cost of an enterprise is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of portable air compressors, in particular to a screwless air pump core. Background technique [0002] The prior art application number is 200420095429.5, the name is: Portable tire inflator, which discloses an inflatable core, including a bracket, a motor is fitted on the upper end of the bracket, and a small gear is fitted on the output shaft, and the small gear meshes with a large gear. The center of the large gear shaft is fitted with a drive shaft, and its bottom end is additionally fitted with a cam integrally formed with the crank. The front and rear journals of the bracket have two concentric oil-impregnated bearings and a cylinder fitted with it. Gas nozzle assembly. The inflatable core needs to be installed with different parts during the assembly process. For example, the motor and the cylinder need to be connected to the bracket, and the cylinder head needs to be installed on the cylinder. A la...

AI Technical Summary

Problems solved by technology

The inflatable core needs to be installed with different parts during the assembly process. For example, the motor and the cylinder need to be connected to the bracket, and the cylinder head needs to be installed on the cylinder. A large number of workers perform the screw locking action, which not only makes the installation more troublesome, increases the labor intensity of the workers, but also greatly increases the manufacturing cost of the enterprise
