Detailed Description

The following are specific embodiments of the present utility model and the technical solutions of the present utility model will be further described with reference to the accompanying drawings, but the present utility model is not limited to these embodiments.

As shown in fig. 1 and 2, the switched reluctance motor comprises a motor main body 1, base plates 2 are arranged on two sides of the bottom of the motor main body 1, extension seats 3 extending outwards are arranged on the front end and the rear end of each base plate 2, mounting grooves 4 axially formed in the direction of the other extension seat 3 by one extension seat 3 are formed in the base plates 2, a plurality of connecting holes 5 are formed in the mounting grooves 4 at intervals transversely, the connecting holes 5 are mounted on a frame or a base in the corresponding working condition field through mounting screws, the longitudinal section of each mounting groove 4 is semicircular, a pressing rod 6 is fixedly mounted in each mounting groove 4, the lower end part of each pressing rod 6 is in a semi-cylindrical shape, the upper end part of each pressing rod 6 is rectangular, limiting grooves communicated with the corresponding mounting grooves 4 are formed in the two inner side walls of each extension seat 3, and limiting assemblies which can be in contact with the limiting surfaces 7 and are used for limiting the pressing rods 6 are arranged in the limiting grooves.

Further, the limiting component is composed of a limiting block 8 with an inclined surface on the outer end face and a spring 9 fixedly arranged between the limiting block 8 and the limiting groove, after the screw is installed in the connecting hole 5, the screw is limited by installing the lower pressing rod 6 in order to prevent the screw from loosening due to long-time working conditions, the surface of the lower end part of the limiting component is contacted with the limiting block 8 in the process of installing the lower pressing rod 6 in the installing groove 4, and due to the inclined arrangement of the outer end face of the limiting block 8 and the action of the spring 9, the spring 9 contracts inwards along with the downward pressing of the lower pressing rod 6, the limiting block 8 moves inwards until the limiting block 8 is pushed down to a corresponding position, and the limiting block 8 pops up to be contacted with the limiting surface 7 on the lower pressing rod 6 so that the lower pressing rod 6 is limited.
