Description
Technical field
The utility model relates to mechanical field, more specifically to a kind of screw assembly.
Background technique
In every profession and trade, screw is all extremely important, screw is the vitals that connects two objects, and some equipment need to be used the screw with spring, place spring between screw and fastening time, rotary screw spring also can rotate along with the rotation of screw, makes troubles to installing.
Summary of the invention
The purpose of this utility model is to overcome prior art deficiency.For achieving the above object, the utility model has adopted following technological scheme:
A kind of screw assembly, comprises screw body, spring and a mounting plate, and described screw body comprises nut and screw rod, nut top is provided with polygonal notch, screw rod is made up of upper and lower two-part, and upper part screw diameter is greater than lower part screw diameter, in upper part screw rod lower end, draw-in groove is set; Described mounting plate arranges a notch corresponding with spring, and notch is provided with an extending groove, and described extending groove is L-type; Described spring one end arranges extending body, and extending body is corresponding with described extending groove; Described spring fitting is between nut and mounting plate, and spring extending body is arranged in notch extending groove.
Described spring diameter is greater than screw diameter and is less than nut diameter.
Described mounting plate notch is made up of upper part groove, lower part penetration hole and extending groove three parts, and upper part groove diameter is greater than lower part penetration hole diameter, and extending groove and upper part groove join, and the extending groove degree of depth is identical with depth of groove.
Described spring diameter is greater than the lower part penetration hole diameter in mounting plate notch, is less than the diameter that groove is divided in notch middle and upper part.
The utlity model has following advantage: can prevent that spring is along with screw rotates and rotates, simple in structure, easy to use.
