Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

It will be understood that when an element is referred to as being "fixed to" another element, it can be directly on the other element or intervening elements may also be present. When a component is considered to be "connected" to another component, it can be directly connected to the other component or intervening components may also be present. When an element is referred to as being "disposed on" another element, it can be directly on the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like are used herein for illustrative purposes only.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this utility model belongs. The terminology used herein in the description of the utility model is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model. The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.

The utility model provides a motor stator, the structure of which is shown in figures 1-4, the motor stator comprises a stator ring 1, a plurality of winding rods 7 are arranged in the stator ring 1, a plurality of connecting grooves 2 are formed in the top end of the stator ring, sliding rods 3 are fixed in the connecting grooves 2, clamping grooves 4 are formed in both sides of the connecting rods, support rings 5 are connected onto the sliding rods 3 in a sliding manner, the support rings 5 are connected with the connecting grooves 2 through first springs 6 encircling the side surfaces of the sliding rods 3, a limiting block 8 is fixed at one end of each winding rod 7, the limiting block 8 is connected with the sliding rods 3 in a sliding manner, grooves 9 are formed in both sides of each limiting block, and inclined clamping blocks 11 matched with the clamping grooves 4 are connected into the grooves 9 through second springs 10. With the motor stator, under the elastic drive of the two second springs 10, the two inclined clamping blocks 11 are respectively connected with the two clamping grooves 4, so that the winding rod 7 is firmly connected on the stator ring 1, and the user requirement is met.

Specifically, the limiting block 8 is matched with the connecting groove 2, so that the limiting block cannot rotate when moving up and down.

Specifically, the number of the connecting grooves 2 is the same as that of the winding rods 7 and corresponds to one.

The working principle of the utility model is as follows: when a plurality of winding rods 7 are installed, the winding rods are firstly in one-to-one correspondence with a plurality of connecting grooves 2, the limiting blocks 8 are positioned in the connecting grooves 2, then the limiting blocks 8 are pressed down to drive the supporting ring 5 to compress the first springs 6, meanwhile, the two inclined clamping blocks 11 are respectively pressed into the grooves 19 and compress the second springs 11 until the grooves 19 move to the clamping grooves 6, and at the moment, the two second springs 11 are reset and drive the two inclined clamping blocks 11 to respectively enter the two clamping grooves 6 for buckling connection, so that the connection of the winding rods 7 is completed; when the winding rod 7 is to be detached, the limiting block 8 is continuously pressed down, the two inclined clamping blocks 11 enter the disengaging clamping grooves 6 respectively under the limiting of the two clamping grooves 6 and are extruded into the grooves 19, the second springs 11 are compressed simultaneously, and the winding rod 7 is detached when the two inclined clamping blocks 11 are completely disengaged from the two clamping grooves 6 respectively.
