FIG. 1 is a schematic perspective view of the structure of the present utility model;
fig. 2 is a schematic diagram showing connection between a limit post and a side block of the structure of the present utility model.
In the figure: 1. a nut body; 2. a threaded positioning hole; 3. a fixed block; 4. a limit column; 5. a side block; 6. a rubber convex pad; 7. an anti-slip bump; 8. and a rubber outer ring.
Detailed Description
The utility model is further described below with reference to examples.
The following examples are illustrative of the present utility model but are not intended to limit the scope of the utility model. The conditions in the examples can be further adjusted according to specific conditions, and simple modifications of the method of the utility model under the premise of the conception of the utility model are all within the scope of the utility model as claimed.
Referring to fig. 1-2, the utility model provides a locking nut of a driving shaft of a split nut, which comprises a nut main body 1, wherein both sides of the inner wall of the nut main body 1 are provided with threaded positioning holes 2 which penetrate through the design, the threaded positioning holes 2 are positioned between adjacent threaded grooves in the nut main body 1, both sides of the outer wall of the nut main body 1 are provided with fixing blocks 3, one side of the fixing blocks 3 close to the nut main body 1 is fixedly connected with a limit column 4, one end of the limit column 4 is in threaded connection with the threaded positioning holes 2, and one side of the nut main body 1 is fixedly connected with a side block 5 in principle of the fixing blocks 3.
