Abstract
The present invention relates to a kind of Anti-loosening nut, comprise the first nut and the second nut that cooperatively interact, one side plane of described first nut is provided with some grooves, described inside grooves nut radial direction is fixed an axle and groove is divided into the first groove and the second groove, be set with reducing " U " shaped element part on the shaft, the side arm of described reducing " U " shaped element part is vertically welded with two pads, be respectively the first pad and the second pad, described first pad and nut plane are inclined to set, Returnning spring is provided with in first groove of lower end, the another side that described second groove bottom is provided with through hole and nut is through, described second nut side uniform plane is provided with some draw-in grooves, described first pad may correspond to and is connected on draw-in groove.Anti-loosening nut of the present invention, easy to use, solve the fastening piece of machine use in the course of the work because the External Force Actings such as vibrations easily produce loosening problem.
Description
Technical field
The present invention relates to a kind of fastening piece, be specifically related to a kind of locking nut preventing loosening.
Background technique
In many mechanical equipment installation engineerings, bolt, nut are one of indispensable accessories, and its effect is coupled together securely equipment components, and equipment is run well.
Nut conventional at present because the External Force Actings such as vibrations easily produce loosening, easily breaks down, affects job schedule in machine operation process.
Summary of the invention
For above-mentioned situation, the object of this invention is to provide a kind of Anti-loosening nut, simple to operate, easy to use, reduce the potential safety hazard in working procedure.
Technological scheme of the present invention is as follows:
A kind of Anti-loosening nut, comprise the first nut and the second nut that cooperatively interact, described first nut, second nut internal diameter is equipped with screw thread, one side plane of described first nut is provided with some grooves, described inside grooves nut radial direction is fixed an axle and groove is divided into the first groove and the second groove, be set with reducing " U " shaped element part on the shaft, the side arm of described reducing " U " shaped element part is vertically welded with two pads, be respectively the first pad and the second pad, correspondence is arranged at the notch of the first groove and the second groove, described first pad and nut plane are inclined to set, Returnning spring is provided with in first groove of lower end, the upper end of Returnning spring and the first pad contacts, the another side that described second groove bottom is provided with through hole and nut is through, inside is provided with screw thread, be threaded screw, described screw connects from the groove opposing side of nut, described second nut side uniform plane is provided with some draw-in grooves, described first pad may correspond to and is connected on draw-in groove.
Preferably, described groove is provided with three, has stability, better can prevent nut loosening.
Anti-loosening nut of the present invention, easy to use, solve the fastening piece of machine use in the course of the work because the External Force Actings such as vibrations easily produce loosening problem.During concrete use, need the used time, by the second nut-welding in the side needing secure component, tighten the first nut, the first pad of the first nut is connected in the draw-in groove of the second nut.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the first nut fragmentary, perspective view of the present invention;
Fig. 3 is the first nut groove sectional drawing of the present invention.
Embodiment
As shown in Figure 1, a kind of Anti-loosening nut, as shown in Figure 1, comprise the first nut 1 and the second nut 2 cooperatively interacted, described first nut 1, second nut 2 internal diameter is equipped with screw thread, as Fig. 2, shown in Fig. 3, one side plane of described first nut 1 is provided with some grooves 2, described groove 2 internal nut radial direction is fixed an axle 3 and groove 2 is divided into the first groove 4 and the second groove 5, described axle 3 is set with reducing " U " shaped element part 6, the side arm of described reducing " U " shaped element part 6 is vertically welded with two pads, be respectively the first pad 7 and the second pad 8, correspondence is arranged at the notch of the first groove 4 and the second groove 5, described first pad 7 and the first nut 1 plane are inclined to set, Returnning spring 9 is provided with in first groove 1, the upper end of Returnning spring 9 contacts with the first pad 7, the another side that described second groove 5 bottom is provided with through hole 10 and the first nut 1 is through, inside is provided with screw thread, be threaded screw 11, described screw 11 connects from groove 2 opposing side of the first nut 1, described second nut 2 side uniform plane is provided with some draw-in grooves 12, described first pad 7 may correspond to and is connected on draw-in groove 12.
During concrete enforcement, need with fastening piece, during as bolt, being inserted by bolt needs in the through hole of secure component, second nut 2 of the present invention welds firmly with needing the opposite side of secure component, the side being provided with draw-in groove 12 is outside, and then tighten the first nut 1, first card 7 of the first nut 1 is connected to the draw-in groove 12 li of the second nut 2, prevent from loosening, when needs are opened, tighten the screw 11 of the second groove 5, the second pad 8 is lived on screw 11 crown, under the effect of screw 11, reducing " U " shaped element part 6 tilts to the first groove 4, first pad 7 compression reseting spring 9, first pad 7 and the first nut 1 side are in same plane, rotate the first nut 1 to open, under the effect of Returnning spring 9, first pad 7 resets.
