Abstract
The utility model discloses a kind of step nut, it is characterized in that: described step nut is " I " type, this step nut comprises three parts, is followed successively by first step part, the second nut part and the 3rd step part; One end of described the second nut part is connected with first step partial fixing, and the other end of the second nut part is fixedly connected with the 3rd step part; Described first step part, the second nut part and the 3rd step part are provided with the through hole running through, and the through-hole inner surface of the second nut part is provided with screw thread; First step part and the 3rd step part are annular, and first step part and the 3rd step part are equipped with four oval holes; The utility model step nut designs meets the requirement of manipulator operation, has improved to a large extent the problems such as tensile strength, has reduced product because the waste that insufficient strength causes provides cost savings.
Description
Technical field
The utility model belongs to nut field, particularly a kind of step nut.
Background technique
Existing nut is because the feature of structure is difficult to meet existing requirement, in use often occur that tensile strength causes product rejection not, the problems such as lock screw difficulty, cause product to cause to a great extent and scrap, increase maintenance cost and lose time, greatly reducing working efficiency.
Model utility content
The purpose of this utility model is to provide a kind of simple in structure, step nut that tensile strength is large.
The technical solution that realizes the utility model object is:
A kind of step nut, is characterized in that: described step nut is " I " type, this step nut comprises three parts, is followed successively by first step part, the second nut part and the 3rd step part; One end of described the second nut part is connected with first step partial fixing, and the other end of the second nut part is fixedly connected with the 3rd step part; Described first step part, the second nut part and the 3rd step part are provided with the through hole running through, and the through-hole inner surface of the second nut part is provided with screw thread; First step part and the 3rd step part are annular, and first step part and the 3rd step part are equipped with four oval holes.
The utility model compared with prior art, its remarkable advantage:
(1) the utility model step nut, is equipped with four oval holes on first step part and the 3rd step part, increases gasket construction intensity, also facilitates manipulator dismounting operation simultaneously.
(2) the utility model step nut, the step part at two ends can increase the integrally-built tensile strength of nut, improves the utilization rate of nut.
Below in conjunction with accompanying drawing, the utility model step nut is described in further detail.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model step nut.
Embodiment
As shown in Figure 1:
A kind of step nut, is characterized in that: described step nut is " I " type, this step nut comprises three parts, is followed successively by first step part, the second nut part and the 3rd step part; One end of described the second nut part is connected with first step partial fixing, and the other end of the second nut part is fixedly connected with the 3rd step part; Described first step part, the second nut part and the 3rd step part are provided with the through hole running through, and the through-hole inner surface of the second nut part is provided with screw thread; First step part and the 3rd step part are annular, and first step part and the 3rd step part are equipped with four oval holes.
