Description

Technical Field

[0001] The utility model belongs to the technical field of anti-loosening and anti-theft nuts, and more specifically, particularly relates to an anti-loosening and anti-theft nut with an extrusion block kit. Background Art

[0002] Anti-loosening and anti-theft nuts are made of special engineering plastics permanently attached to the threads. During the tightening process of the internal and external threads, the engineering plastics are squeezed to generate a strong reaction force, which greatly increases the friction between the internal and external threads and provides absolute resistance to vibration.

[0003] Based on the above, the inventors have found the following problems: during the use of existing anti-loosening and anti-theft nuts, they are directly installed by rotating them with a wrench, but when they are used in a fixed manner, when the frequent vibration amplitude is large, the nuts will shake and then become loose, which indirectly reduces the efficiency of use.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and an anti-loosening and anti-theft nut with an extrusion block kit is provided, in order to achieve the purpose of having more practical value. Utility Model Content

[0005] The purpose and effect of the anti-loosening and anti-theft nut with an extrusion block kit of the utility model are achieved by the following specific technical means:

[0006] A loosening and theft-proof nut with an extrusion block kit comprises a nut body, a ring is fixedly installed on the bottom end of the nut body, a mounting thread is arranged inside the nut body, a group of grooves are opened on the inner wall of the nut body, and an extrusion mechanism is installed inside the grooves.

[0007] Furthermore, the bottom end surface of the circular ring is provided with a plurality of groups of thrust teeth.

[0008] Furthermore, the extrusion mechanism comprises a rotating rod, a surface of which is provided with threads, and one end of the rotating rod is rotatably connected to the extrusion block.

[0009] Furthermore, a group of threaded holes are arranged on the surface of the nut body, the rotating rod is installed through the inside of the threaded holes, and the threads are engaged with the threaded holes.

[0010] Furthermore, the extrusion block is installed inside the groove.

[0011] Furthermore, the surface of the nut body is plated with a rust inhibitor.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] Through the design of the thrust teeth, the staff will press the bottom end of the ring against the surface of the object when using the nut for installation. At the same time, under the action of the thrust teeth, the vibration amplitude of the nut body can be effectively reduced, reducing the possibility of loosening, and indirectly improving the use efficiency of the nut. It is very simple.

[0014] Through the cooperation between the thread and the threaded hole, after the staff uses a wrench to install the nut, they can rotate the rotating rod to squeeze the extrusion block toward the internal bolt surface, which can effectively increase the internal clamping force. The operation steps are very simple and the design greatly increases practicality. BRIEF DESCRIPTION OF THE DRAWINGS
