Description

Technical Field

[0001] This utility model relates to the field of anti-loosening nuts, specifically an anti-loosening nut for secure connection. Background Technology

[0002] Lock nuts, also known as anti-loosening nuts, are a common type of fastening nut. They include mechanical locking mechanisms, riveting locking mechanisms, friction locking mechanisms, and structural locking mechanisms.

[0003] Utility model patent CN218625006U discloses a slotted flange anti-loosening nut that facilitates connection, belonging to the field of connection facilitation technology. This utility model's slotted flange anti-loosening nut for easy connection includes an octagonal nut body, a fastening assembly, and a flange assembly. The fastening assembly is located on top of the octagonal nut body and is fixedly connected to it. The flange assembly is located below the octagonal nut body, and the flange assembly and octagonal nut body are integrated into one structure. By fixing the fastening assembly to the octagonal nut body, the connection stability of the octagonal nut body is improved, effectively reducing the possibility of tilting or detachment during the connection process between the nut and the connecting bolt. This addresses the problem of current market slotted flange anti-loosening nuts directly connecting to the connecting bolt via a slot, which inevitably leads to tilting or detachment during operation, reducing practicality.

[0004] However, the aforementioned device still has some drawbacks in practical use. A significant one is the lack of a positioning component for the anti-loosening nut after installation. Under continuous vibration, the contact surface wears down, reducing the frictional torque and weakening the anti-loosening effect, ultimately preventing the nut from securing the object. Therefore, to solve this problem, we propose a more secure anti-loosening nut. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a secure, non-loosening nut.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A securely fastened anti-loosening nut includes a connecting screw rod with several positioning holes on its exterior. A nut base is threaded onto the exterior of the connecting screw rod. A washer is connected to the bottom of the nut base, and the bottom of the washer has anti-slip texture. Positioning components are connected to both sides of the top of the nut base. Each positioning component includes a U-shaped frame. A moving groove is formed at both ends of the inner wall of the U-shaped frame. A moving rod is connected to the inner wall of the moving groove. A return spring and a moving block are respectively fitted onto the exterior of the moving rod. A damping hole is formed at one end of each of the two moving blocks, and a damping shaft is installed between the two damping holes.

[0008] Preferably, the gasket is sleeved on the outside of the connecting screw, and the bottoms of the two U-shaped brackets are respectively connected to the two sides of the top of the nut base.

[0009] Preferably, the outer side of the movable block slides in contact with the inner wall of the movable groove, and a movable hole is provided through the movable block for use with the movable rod.

[0010] Preferably, one side of the reset spring is connected to one side of the inner wall of the moving groove, and the other side of the reset spring is connected to the moving block.

[0011] Preferably, the damping shaft is externally fixed with a rotating plate, and the top of each of the two rotating plates on opposite sides is connected with a positioning rod. The positioning rod is used in conjunction with the positioning hole, and the rotating plate is located inside the U-shaped frame.

[0012] Preferably, a limiting groove is provided at the bottom of the inner wall of the U-shaped frame, and a limiting strip that cooperates with the limiting groove is connected to the bottom of the rotating plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention utilizes the cooperation of a positioning component and a positioning hole. The nut base and washer are fitted onto the top of the connecting screw. Rotating the nut base downwards, the nut base is finally threaded onto the outside of the connecting screw. The two rotating plates move away from each other, stretching the return spring. Then, rotating the rotating plates to a vertical position and stopping the movement causes the return spring to reset, allowing the positioning rod to enter the positioning hole, thus completing the positioning of the positioning component and improving the stability of the nut base.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Please see Figures 1-4 A securely fastened anti-loosening nut includes a connecting screw 1, with several positioning holes 4 on the outside of the connecting screw 1. A nut base 2 is threaded onto the outside of the connecting screw 1. A washer 5 is connected to the bottom of the nut base 2. The bottom of the washer 5 has anti-slip texture 6. Positioning components 3 are connected to both sides of the top of the nut base 2. The positioning components 3 include a U-shaped frame 31. Both ends of the inner wall of the U-shaped frame 31 have moving grooves 37. The inner wall of the moving grooves 37 is connected to a moving rod 32. A return spring 39 and a moving block 35 are respectively fitted onto the outside of the moving rod 32. A damping hole 310 is opened at the opposite end of the two moving blocks 35. A damping shaft 311 is installed between the two damping holes 310.

[0022] As a technical optimization of this utility model, the gasket 5 is sleeved on the outside of the connecting screw 1, and the bottom of the two U-shaped brackets 31 are respectively connected to the two sides of the top of the nut base 2. Through the gasket 5, the pressure of the nut base 2 can be distributed, the wear of the nut base 2 can be reduced, and the nut base 2 can also have the function of preventing loosening.

[0023] As a technical optimization of this utility model, the outer side of the moving block 35 slides in contact with the inner wall of the moving groove 37, and a moving hole is provided through the moving block 35 to cooperate with the moving rod 32; the moving hole facilitates the movement of the moving block 35 on the moving rod 32.

[0024] As a technical optimization of this utility model, one side of the reset spring 39 is connected to one side of the inner wall of the moving groove 37, and the other side of the reset spring 39 is connected to the moving block 35; the reset spring 39 facilitates the reset of the moving block 35 after it has moved.

[0025] As a technical optimization of this utility model, a rotating plate 33 is fixedly sleeved on the outside of the damping shaft 311. The top of each of the two rotating plates 33 on opposite sides is connected to a positioning rod 34. The positioning rod 34 is used in conjunction with the positioning hole 4. The rotating plate 33 is located inside the U-shaped frame 31. Through the cooperation of the positioning rod 34 and the positioning hole 4, the nut base 2 can be positioned, thereby improving the stability of the nut base 2.

[0026] As a technical optimization of this utility model, a limiting groove 38 is provided at the bottom of the inner wall of the U-shaped frame 31, and a limiting strip 36 that works in conjunction with the limiting groove 38 is connected to the bottom of the rotating plate 33; the stability of the left and right movement of the rotating plate 33 is improved by the cooperation of the limiting groove 38 and the limiting strip 36.

[0027] In use, the nut base 2 and washer 5 are fitted onto the top of the connecting screw 1. The nut base 2 is rotated downwards until it is threaded onto the outside of the connecting screw 1. The two rotating plates 33 are moved to opposite sides, stretching the return spring 39. Then, the rotating plates 33 are rotated to a vertical position. When the rotation of the rotating plates 33 is stopped, the return spring 39 returns to its original position, causing the rotating plates 33 to return to their original position. This allows the positioning rod 34 to enter the positioning hole 4, completing the positioning of the positioning component 3 and improving the stability of the nut base 2.
