Description

Technical Field

[0001] The utility model belongs to the technical field of nuts and relates to an anti-loosening nut, in particular to an anti-loosening nut. Background Art

[0002] A nut is a part that is screwed together with a screw to tighten the bolt. A nut is a part that tightly connects mechanical equipment. Nuts and bolts of the same specifications can be connected together through the inner thread.

[0003] Most of the nuts on the market do not have a reinforcement structure. However, due to the spiral fastening structure of the screw and the nut, the nut will become loose during long-term use due to the influence of external factors, which can easily affect the stability of the fastened equipment or building. Therefore, it is of great significance to design an anti-loosening nut. Summary of the invention

[0004] The utility model aims to provide an anti-loosening nut in view of the above problems existing in the prior art.

[0005] The purpose of the utility model can be achieved through the following technical solutions: an anti-loosening nut, including a nut body, characterized in that a protection unit composed of a left shell and a right shell is arranged on the outside of the nut body, two top plates are symmetrically arranged on the top of the protection unit, and friction pads are symmetrically arranged on the two top plates, guide rods are symmetrically arranged on both sides of the right shell, bolts are arranged on the guide rods, guide grooves are symmetrically opened on both sides of the left shell, and threaded holes are opened in the guide grooves.

[0006] In the above-mentioned anti-loosening nut, a plurality of symmetrical tension springs are fixedly arranged between the two sides of the nut body and the protection unit.

[0007] In the above-mentioned anti-loosening nut, two symmetrical extrusion plates are movably provided on the top of the protection unit.

[0008] In the above-mentioned anti-loosening nut, limit rods are symmetrically arranged on both sides of the extrusion plate, and a limit groove used in conjunction with the limit rod is opened on the top of the protection unit.

[0009] Compared with the prior art, the anti-loosening nut increases the friction between the nut body and the screw by making the friction pad in close contact with the surface of the screw, making the nut body more stable and less likely to loosen during use, and the protective unit can protect the nut body.

[0015] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0016] like Figure 1 , 2 As shown in Figures 3 and 4, the anti-loosening nut comprises a nut body 1. A protection unit 2 consisting of a left shell 3 and a right shell 4 is arranged outside the nut body 1. Two top plates 5 are symmetrically arranged on the top of the protection unit 2, and friction pads 6 are symmetrically arranged on the two top plates 5. Guide rods 7 are symmetrically arranged on both sides of the right shell 4, and bolts 8 are arranged on the guide rods 7. Guide grooves 9 are symmetrically opened on both sides of the left shell 3, and threaded holes 10 are opened in the guide grooves 9. When the nut body 1 is used in conjunction with the screw, the protection unit 2 is in a combined state. At this time, the protection unit 2 is fixedly arranged on the protection unit 2. The top plates 5 on the top plates 5 are merged, and the friction pads 6 on the top plates 5 will fit tightly against the surface of the screw. The friction pads 6 increase the friction between the nut body 1 and the screw, so that the nut body 1 is more stable during use and is not easy to loosen, and the protection unit 2 can protect the nut body 1, and the guide rods 7 and the guide grooves 9 can guide the opening and closing movements of the protection unit 2. After the protection units 2 are merged, the merged protection units 2 can be fixed by using the bolts 8 and the threaded holes 10, so that the friction pads 6 can stably and tightly fit against the surface of the screw.

[0017] Preferably, a plurality of symmetrical tension springs 11 are fixedly provided between the two sides of the nut body 1 and the protection unit 2 , and when not affected by external forces, the protection unit 2 can merge by itself through the force of the tension springs 11 to protect the nut body 1 .

[0018] Preferably, two symmetrical extrusion plates 12 are movably provided on the top of the protection unit 2. When the nut body 1 is disassembled, the bolts 8 fixing the protection unit 2 are released. By pressing the extrusion plate 12, the extrusion plate 12 will open the left shell 3 and the right shell 4, so that the friction pad 6 will not contact the surface of the screw, thereby facilitating the disassembly of the nut body 1. After the disassembly is completed, the extrusion plate 12 is pushed to reset, and the protection unit 2 is automatically combined to protect the nut body 1 under the action of the tension spring 11.

[0019] Preferably, limiting rods 13 are symmetrically arranged on both sides of the extrusion plate 12, and a limiting groove 14 used in conjunction with the limiting rod 13 is opened on the top of the protective unit 2. The use of the limiting rod 13 and the limiting groove 14 can limit the movement of the extrusion plate 12, and the extrusion plate 12 can support the protective unit 2 in an open state.

[0020] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0021] Although the present invention uses more terms such as nut body 1, protection unit 2, left housing 3, right housing 4, top plate 5, friction pad 6, guide rod 7, bolt 8, guide groove 9, threaded hole 10, tension spring 11, extrusion plate 12, limit rod 13, limit groove 14, etc., it does not exclude the possibility of using other terms. These terms are used only to more conveniently describe and explain the essence of the utility model; interpreting them as any additional restrictions is contrary to the spirit of the utility model.
