Description

A kind of plastic packaging motor is with the mounting structure of end cap

Technical field:

The utility model relates to the mounting structure of a kind of plastic packaging motor with end cap.

Background technology:

The traditional plastic packaging motor housing and the mounting structure of end cap; Usually adopt gap fiting mode,, reach the purpose of cooperation through changing the internal diameter size tolerance of end cap and plastic packaging housing; This structural reliability is not high; In actual production and use, occur loosening, the dropping situations of end cap easily, potential safety hazard is big, has a strong impact on the normal use of motor.

Summary of the invention:

The purpose of the utility model provides the mounting structure of a kind of plastic packaging motor with end cap, and this is simple in structure, and end cap and plastic packaging housing are installed fastening, good reliability, have solved problems such as end cap becomes flexible, comes off.

The purpose of the utility model is achieved through following technical proposals.

A kind of plastic packaging motor comprises plastic packaging housing and end cap with the mounting structure of end cap, and end cap is nested with the plastic packaging housing; Plastic packaging housing the inside parcel stator module, the middle cavity that is formed for installing rotor assembly of plastic packaging housing, end cap protrudes cylinder downwards; Cylinder embeds in the cavity and with the plastic packaging shell end and cooperates; The end internal face of the cavity of plastic packaging housing is offered some grooves, and the lateral wall of cylinder protrudes some fixture blocks, and fixture block embeds in the groove.

Above-mentioned described cylinder is annular, and groove is set in the middle of the cylinder.

Above-mentioned described plastic packaging housing is injection mo(u)lding, and an end of plastic packaging housing is provided with the housing bearing chamber.

Above-mentioned described plastic packaging inner walls is provided with step, and wiring board is bearing on the step.

In the middle of the above-mentioned described end cap bearings mounted bearing chamber, the nested damping washer in end cap bearing outside are set.

Above-mentioned described some fixture blocks are 2 or more than 2.

The utility model compared with prior art; Have following effect: 1) the utility model is offered some grooves through the end internal face at the cavity of plastic packaging housing; The lateral wall of cylinder protrudes some fixture blocks, and fixture block embeds in the groove, makes end cap and plastic packaging housing that fastening, good reliability is installed; Effectively avoid having solved problems such as end cap becomes flexible, comes off owing to size cooperates cause loosening; 2) described cylinder is annular, in the middle of the cylinder groove is set, and groove makes cylinder have elasticity, and is easy for installation; 3) some fixture blocks are 2 or more than 2, and end cap is stressed evenly, guarantee that end cap and plastic packaging housing are fastened together.
