Description

Technical Field

[0001] The utility model relates to the technical field of nuts, in particular to a reduced-diameter slotted anti-loosening nut. Background Art

[0002] A nut is a nut that is screwed together with a bolt or screw for tightening. The inner thread is connected to the outer thread of the bolt through rotation. Only nuts and bolts of the same specifications can be connected together.

[0003] The fastening of nuts and bolts is generally relatively stable, but in the prior art, if the fasteners are in vibration for a long time, there will be a difference in vibration frequency between the connecting parts, which will cause a certain displacement between the connecting parts in the connecting structure, causing the connection between the nut and the stud to become loose or even fall off, which is not practical enough. Therefore, it is necessary to redesign a reduced diameter slit anti-loosening nut to address the above problem. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and provides a reduced-diameter slotted anti-loosening nut.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

The inner wall of the locking nut is slidably installed with two connecting plates through an installation groove, the ends of the two connecting rods are respectively fixedly connected to the outer walls of the connecting plates on the same side, and the outer walls of the two connecting plates are fixedly installed with multiple limiting plates, the upper end surface of the locking nut is fixedly installed with a rotating nut through a supporting mechanism, the outer wall of the locking nut is fixedly installed with a connecting frame through a connecting mechanism, a stud bolt is rotatably installed inside the connecting frame, and the outer wall of the stud bolt is threadedly installed with two movable plates through a limiting mechanism.

[0012] Beneficial effects of the utility model:

[0013] 1. By setting components such as connecting plates, limit plates, connecting rods and springs, the fixed spring drives the connecting plate to move through the connecting rod, and the connecting plate can drive the limit plate to insert into the thread of the screw. Because each limit plate is set horizontally, when it is inserted into the thread, it can limit the outer thread of the screw and the inner thread of the locking nut, thereby preventing it from loosening.

[0014] 2. By setting up components such as stud bolts, limit rods, movable plates and anti-skid pads, the stud bolts drive the two movable plates to move by cooperating with the limit rods. When the two movable plates are close to each other, they can respectively drive the anti-skid pads to clamp the outer wall of the screw. The anti-skid pads increase the friction force to prevent the locking nut from loosening, thereby preventing the limit plate from damaging the screw threads when loosening.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-5 The outer wall of the two connecting rods 3 is fixed with a shift block 4, and the inner wall of the two shift blocks 4 is connected to the outer wall of the locking nut 1 through a fixing mechanism. The fixing mechanism includes a fixing spring 5 installed on the outer wall of the connecting rod 3, and the two ends of the fixing spring 5 are elastically connected to the outer wall of the locking nut 1 and the inner wall of the shift block 4 respectively. The inner wall of the locking nut 1 is slidably installed with two connecting plates 6 through the mounting groove, and the ends of the two connecting rods 3 are respectively fixedly connected to the outer wall of the connecting plate 6 on the same side, and the outer walls of the two connecting plates 6 are fixedly installed with multiple limiting plates 7, and the thickness of each limiting plate 7 is the same as the gap between the screw threads, and the limiting plate 7 can be accurately stuck in the gap between the screw threads.

[0023] A rotating nut 9 is fixedly installed on the upper end surface of the locking nut 1 through a supporting mechanism, and the supporting mechanism includes two supporting columns 8 fixedly installed on the upper end surface of the locking nut 1, and the ends of the two supporting columns 8 are fixedly connected to the bottom wall of the rotating nut 9. A connecting frame 11 is fixedly installed on the outer wall of the locking nut 1 through a connecting mechanism. The connecting mechanism includes a connecting rod 10 fixedly installed on the outer wall of the locking nut 1, and the end of the connecting rod 10 is fixedly connected to the outer wall of the connecting frame 11. A stud 12 is rotatably installed inside the connecting frame 11, and two movable plates 14 are threadedly installed on the outer wall of the stud 12 through a limiting mechanism. The limiting mechanism includes a limiting rod 13 fixedly installed inside the connecting frame 11, and the limiting rod 13 slides through the two movable plates 14. The limiting rod 13 can limit the two movable plates 14, so that the two movable plates 14 can only move axially along the outer wall of the stud 12. The inner walls of the two movable plates 14 are fixedly installed with anti-slip pads 15, and the two anti-slip pads 15 are made of rubber.

[0024] When the utility model is used, a wrench can be used to twist the rotating nut 9, so that it drives the locking nut 1 to rotate through the two support columns 8. While rotating, the shifting block 4 can be moved to drive the connecting plate 6 to move inside the installation groove through the connecting rod 3. When the locking nut 1 completes the connection with the screw, the shifting block 4 can be loosened to allow the fixing spring 5 to drive the limiting plate 7 to move through the connecting rod 3. The connecting plate 6 can drive the limiting plate 7 to insert into the thread of the screw. Because each limiting plate 7 is horizontally arranged, when it is inserted into the thread, it can achieve the limit between the outer thread of the screw and the inner thread of the locking nut 1, thereby preventing it from loosening.

[0025] The gap of the locking seam can also be adjusted by rotating the hexagon socket bolt 2, so that the tightness of the locking nut 1 can be conveniently adjusted. When the connection is completed, the stud bolt 12 can be rotated by a wrench, and the stud bolt 12 drives the two movable plates 14 to move by cooperating with the limit rod 13. When the two movable plates 14 are close to each other, they can respectively drive the anti-skid pads 15 to clamp the outer wall of the screw. Since the anti-skid pads 15 are made of rubber material, rubber has good anti-skid properties, and a layer of tiny convex structures are generally formed on the rubber surface. These convex structures form a small "suction cup" that can absorb and keep the surface of an object firmly attached to the rubber material to prevent sliding, and the rubber material has good elasticity and softness, which enables it to form a closer contact between the surface and the bolt thread, thereby increasing friction and improving the friction coefficient. By increasing friction, the locking nut 1 can be prevented from loosening, thereby preventing the limit plate 7 from damaging the screw thread when loosening.

[0026] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
