SUMMERY OF THE UTILITY MODEL

In view of the defects existing in the prior variable speed motor, the utility model aims to solve the technical problem that: the variable speed motor for the safe box is more reasonable in design, convenient to assemble and firm in assembly of all parts after assembly.

In order to achieve the above object, according to one aspect of the present invention, the present invention is realized by the following technical measures: a variable speed motor for a safe, comprising:

the motor rear shell is internally hollow with an opening on the bottom surface, the opening side of the bottom surface of the motor rear shell is movably sealed by a sealing cover, a fixed column extends upwards from the top surface of the motor rear shell, and an opening is formed in one side of the fixed column;

the motor body is arranged in the motor rear shell, a power gear of the motor body is opposite to the opening of the fixed column, and clamping teeth of part of the power gear are positioned on the outer side of the fixed column;

the motor front shell is arranged at the top of the motor rear shell, a terminal output shaft is fixed at the center of the motor front shell, the top end of the terminal output shaft extends out of the motor front shell, the bottom end of the terminal output shaft is inserted and fixed at the top of the fixed column, and meanwhile, a driven gear is also arranged on the terminal output shaft;

and one end of a central shaft of the reduction gear set is inserted in the front shell of the motor, the other end of the central shaft of the reduction gear set is inserted and fixed on the top surface of the rear shell of the motor, and the reduction gear set is connected with the power gear and the driven gear.

This a variable speed motor for safe is through setting up a motor backshell, assembles can be more convenient than iron buckle and fan-shaped support, fixes through motor backshell and motor front shell simultaneously, and the part in two motor shells is fixed will be more firm.

Further, the power of the motor body is a national standard R300 micro motor. The design reduces the consumption of the copper coil in the motor body, thereby reducing the production cost.

Furthermore, a clamping interface is formed in the top surface of the motor rear shell, a clamping joint is arranged in the motor front shell, and the motor front shell is clamped in the clamping interface of the motor rear shell through the clamping joint to enable the motor rear shell and the motor rear shell to be fixed. The mutual fixation between two motor casings is convenient for through the design.

Compared with the prior art, the utility model has the advantages of: 1. the variable speed motor is convenient to install; 2. all parts are firmly fixed; 3. the production cost is reduced.
