Abstract
The invention discloses a screw component provided with a spring. The screw component comprises a screw body, the spring and a mounting plate, wherein the screw body comprises a nut and a screw rod, a polygonal notch is formed in the top of the nut, the screw rod consists of upper and lower parts, the diameter of the upper-part screw rod is larger than that of the lower-part screw rod, and a clamping groove is formed in the lower end of the upper-part screw rod; a notch corresponding to the spring is formed in the mounting plate, and a spring fixing ring is arranged in the notch; the spring is arranged between the nut and the mounting plate and is fixed and prevented from rotating by the spring fixing ring. The screw component has the advantages as follows: the spring can be prevented from rotating along with the rotation of the screw body, and the screw component is simple in structure and convenient to use.
Description
Technical field
The present invention relates to mechanical field, more specifically to a kind of screw assembly with spring.
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 object of the invention is to overcome prior art deficiency.For achieving the above object, the present invention has adopted following technological scheme:
A kind of screw assembly with spring, comprise screw body, spring and a mounting plate, 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, 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, is provided with spring retaining ring in notch; Described spring is between nut and mounting plate, and spring is by its rotation of the fixing prevention of spring retaining ring.
Described spring diameter is greater than screw diameter and is less than nut diameter.
Described mounting plate notch is made up of two-part, upper part groove and lower part penetration hole, and upper part groove diameter is greater than lower part penetration hole diameter, and spring retaining ring is arranged in part 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 present invention has advantages of as follows: can prevent that spring is along with screw rotates and rotates, and simple in structure, easy to use.
Brief description of the drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation after screw, spring are connected with mounting plate;
Fig. 3 is that clip is stuck in the schematic diagram on draw-in groove.
Wherein, 1, nut; 2, screw rod; 3, draw-in groove; 4, spring; 5, mounting plate; 6, spring retaining ring; 7, clip; 8, groove; 9, penetration hole.
Embodiment
With the drawings and specific embodiments, the present invention is further detailed explanation below.
As shown in the figure, a kind of screw assembly with spring, comprise screw body, spring 4 and a mounting plate 5, described screw body comprises nut 1 and screw rod 2, nut 1 top is provided with polygonal notch, screw rod 2 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 3 is set; Described mounting plate 5 arranges a notch corresponding with spring 4, is provided with spring retaining ring 6 in notch; Described spring 4 is between nut 1 and mounting plate 5, and spring 4 is by fixing its rotation of prevention of spring retaining ring 6.
Described spring 4 diameters are greater than screw rod 2 diameters and are less than nut 1 diameter.
Described mounting plate 5 notches are made up of two-part, upper part groove 8 and lower part penetration hole 9, and upper part groove 8 diameters are greater than lower part penetration hole 9 diameters, and spring retaining ring is arranged in part groove 8.
Described spring 4 diameters are greater than lower part penetration hole 9 diameters in mounting plate 5 notches, are less than the diameter that groove 8 is divided in notch middle and upper part.
When use, one, spring is passed to spring retaining ring, effectively prevent from the time of turn screw, spring being driven.
