Description

Technical Field

[0001] The utility model relates to the technical field of fasteners, in particular to the technical field of locking nuts. Background Art

[0002] Locking nuts are widely used in machinery and other industries. Their working principle is to use the friction between the nut and the bolt for self-locking. However, the reliability of this self-locking will be reduced under dynamic loads. In some important occasions, we will take some anti-loosening measures to ensure the reliability of nut locking. Anti-loosening measures will make it difficult to disassemble the nut, which will bring certain difficulties to the repair and maintenance of the subsequent facilities or equipment. Summary of the invention

[0004] To achieve the above-mentioned purpose, the utility model proposes a locking nut which is easy to disassemble, including a main nut, an auxiliary cylinder, an auxiliary ring, a spring, a connecting rod, a clamping block, and a clamping groove. There are two main nuts, a main threaded hole is provided on the main nut, and an auxiliary cylinder is fixed on the upper end surface of the main nut. The auxiliary cylinder and the main nut are an integrated structure. The auxiliary cylinder and the main threaded hole are located on the same axis, the inner diameter of the auxiliary cylinder is larger than the inner diameter of the main threaded hole, an external thread is provided on the outer wall of the auxiliary cylinder, the auxiliary ring is in a circular ring shape, and an internal thread matching the external thread is provided on the inner wall of the auxiliary ring. The auxiliary ring is screwed on the auxiliary cylinder, and the spiral direction of the internal thread is the same as the spiral direction of the thread in the main threaded hole. A spring is clamped between the main nut and the auxiliary ring, and the spring is in a compressed state. The connecting rod intersects and is perpendicular to the central axes of the two main nuts, clamping blocks are provided at both ends of the connecting rod, and a clamping groove matching the clamping block is provided on the side wall where the spacing between the two auxiliary rings is the smallest, and the two clamping blocks are respectively embedded in the two clamping grooves.

[0005] Preferably, the upper end surface of the main nut and the lower end surface of the auxiliary ring are both provided with embedding grooves, and the upper and lower ends of the spring are respectively embedded in the two embedding grooves.

[0006] Preferably, the slot is T-shaped.

[0007] Preferably, the slot is open on both the side wall and the top wall of the auxiliary ring, and a magnet is fixed on the wall of the slot parallel to the bottom wall of the auxiliary ring.

[0008] The beneficial effects of the utility model are as follows: the utility model screws two auxiliary rings onto the auxiliary cylinders on the two main nuts respectively, a connecting rod connects the two auxiliary rings, and a spring is sandwiched between the auxiliary ring and the main nut, so that when the main nut has a tendency to loosen, it will be subjected to great pressure from the spring, making it difficult for the nut to loosen.

[0014] See also Figure 1 , Figure 2 , Figure 3 The utility model is a locking nut that is easy to disassemble, comprising a main nut 1, an auxiliary tube 11, an auxiliary ring 2, a spring 3, a connecting rod 4, a clamping block 41, and a clamping groove 21. The main nut 1 has two parts, a main threaded hole 10 is provided on the main nut 1, an auxiliary tube 11 is fixed on the upper end surface of the main nut 1, the auxiliary tube 11 and the main nut 1 are an integrated structure, the auxiliary tube 11 and the main threaded hole 10 are located on the same axis, the inner diameter of the auxiliary tube 11 is larger than the inner diameter of the main threaded hole 10, an external thread is provided on the outer wall of the auxiliary tube 11, and the auxiliary ring 2 is in a circular ring shape. An internal thread matching the external thread is provided on the inner wall of the auxiliary ring 2. The auxiliary ring 2 is screwed on the auxiliary tube 11. The spiral direction of the internal thread is the same as the spiral direction of the thread in the main threaded hole 10. A spring 3 is clamped between the main nut 1 and the auxiliary ring 2. The spring 3 is in a compressed state. The connecting rod 4 intersects and is perpendicular to the central axes of the two main nuts 1. Blocks 41 are provided at both ends of the connecting rod 4. A slot 21 matching the block 41 is provided on the side wall where the distance between the two auxiliary rings 2 is the smallest. The two blocks 41 are respectively embedded in the two slots 21.

[0015] The upper end surface of the main nut 1 and the lower end surface of the auxiliary ring 2 are both provided with embedding grooves, and the upper and lower ends of the spring 3 are respectively embedded in the two embedding grooves.

[0016] The slot 21 is T-shaped.

[0017] In order to prevent the block 41 from being separated from the slot 21 , the slot 21 is open at both the side wall and the top wall of the auxiliary ring 2 . A magnet 22 is fixed on the wall of the slot 21 parallel to the bottom wall of the auxiliary ring 2 , and the magnet 22 attracts the block 41 .

[0018] Working process of this utility model:

[0019] During the working process of the locking nut which is easy to disassemble, the two main nuts 1 are screwed onto two adjacent screw rods respectively, and after tightening, the spring 3 is sleeved on the outside of the auxiliary tube 11, and the bottom end of the spring 3 is embedded in the embedding groove on the main nut 1, and then the auxiliary ring 2 is screwed onto the auxiliary tube 11, and the auxiliary ring 2 presses the spring 3 downward to make it in a compressed state, and the auxiliary ring 2 is adjusted so that the two auxiliary rings 2 are basically at the same horizontal height and the slots 21 are opposite, and then the connecting rod 4 is installed between the two auxiliary rings 2, and the blocks 41 at both ends of the connecting rod 4 are respectively inserted into the two slots 21 during installation to complete the installation. When the main nut 1 tends to loosen, since the two auxiliary rings 2 are connected by the connecting rod 4, the auxiliary ring 2 cannot rotate, and the auxiliary ring 2 cannot move up and down, and the main nut 1 will have a tendency to approach the auxiliary ring 2. Due to the existence of the spring 3, the main nut 1 will be subjected to a large downward pressure, and the main nut 1 is difficult to move upward, which makes it difficult to loosen.

[0020] When the nut needs to be removed, first remove the connecting rod 4, then remove the auxiliary ring 2 and the spring 3, and finally remove the main nut 1. The nut is easy to remove, which is convenient for the later maintenance and repair of the equipment or facilities.

[0021] The above embodiments are intended to illustrate the present invention, not to limit the present invention. Any solution that is a simple transformation of the present invention falls within the protection scope of the present invention.
