[0024] 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.

[0025] Reference Figure 1-Figure 7 A new type of anti-loosening nut includes a basic body 4 and a device body 1. A circular hole 2 is opened inside the device body 1. The top and bottom ends of the basic body 4 are respectively provided with a first threaded portion 6 and a second threaded portion 5. The first threaded portion 6 passes through the circular hole 2 from bottom to top. A nut body 7 is provided on the outer wall of the first threaded portion 6. An anti-loosening mechanism is provided inside the nut body 7 to prevent the nut from loosening itself.

[0026] As a technical optimization solution in the present invention, the inner wall of the nut body 7 is provided with a third threaded portion 10, and the first threaded portion 6 is threadedly connected to the third threaded portion 10. The nut body 7 can be threadedly connected to the first threaded portion 6 through the third threaded portion 10 provided on the inner wall, so that the nut body 7 and the basic body 4 can be connected and fixed.

[0027] As a technical optimization solution in the utility model, a rubber ring 9 is installed between the basic body 4 and the first threaded portion 6, and the rubber ring 9 is in contact with the top of the equipment body 1. After the nut body 7 is threadedly installed on the surface of the first threaded portion 6, the top of the nut body 7 is closely in contact with the inner top surface of the equipment body 1. As the nut body 7 continues to be tightened on the surface of the first threaded portion 6, the rubber ring 9 is driven to be closely in contact with the outer top surface of the equipment body 1, so that the rubber ring 9 is compressed and deformed, filling the gap between the basic body 4 and the equipment body 1, thereby forming a structure with a certain sealing performance. This design can effectively avoid oil leakage, water leakage and the like between working parts under high temperature, high pressure or high speed environment, thereby extending the service life of the equipment; in addition, the rubber ring 9 can also play a role in preventing loosening. In some working environments, due to vibration or other reasons, the nut body 7 may loosen by itself, causing damage to the equipment or system. The rubber ring 9 can increase the friction and shock resistance between the basic body 4 and the equipment body 1, prevent the nut body 7 from loosening, thereby improving safety and stability to a certain extent.

[0028] As a technical optimization solution in the present invention, the edges of the basic body 4 and the nut body 7 are all rounded, and the surfaces of the first threaded portion 6, the second threaded portion 5 and the third threaded portion 10 are all coated with an anti-corrosion coating. In actual use, the setting of the rounded edges can increase the grip feel on the one hand, and on the other hand, it can facilitate the insertion of the hexagonal wrench and facilitate construction; the setting of the anti-corrosion coating can effectively increase the service life of the first threaded portion 6, the second threaded portion 5 and the third threaded portion 10.

[0029] As a technical optimization solution in the present invention, the outer wall of the basic body 4 and the outer wall of the nut body 7 are both provided with an outer anti-rust coating, and the inner wall of the basic body 4 is provided with an inner anti-rust coating. By providing the inner anti-rust coating and the outer anti-rust coating, the anti-corrosion ability of the inner and outer walls of the basic body 4 and the outer wall of the nut body 7 can be effectively increased, and the service life of the basic body 4 and the nut body 7 can be improved.

[0030] As a technical optimization solution in the present invention, the anti-loosening mechanism includes a slot 11 opened on the diagonal side of the nut body 7, and the slot 11 divides the diagonal side of the nut body 7 into an upper half 13 and a lower half 14. Figure 7 As shown, after being divided by the groove 11, the upper part 13 is thinner than the lower part 14 to facilitate subsequent operations.

[0031] As a technical optimization solution in the utility model, the upper half 13 and the lower half 14 are respectively provided with a light hole 12 and a threaded hole 3, and the nut body 7 is provided with a screw 8, which passes through the light hole 12 and is threadedly connected with the threaded hole 3. When the third threaded portion 10 of the inner wall of the nut body 7 is threadedly connected with the first threaded portion 6, and the nut body 7 is tightened on the surface of the first threaded portion 6, the screw 8 is placed in the light hole 12, and the top of the screw 8 passes through the light hole 12 and is threadedly matched with the threaded hole 3, so that the screw 8 can be screwed into the threaded hole 3, thereby driving the upper half 13 to move a certain distance, and as the screw 8 continues to be tightened in the threaded hole 3, the upper half 13 and the lower half 14 can be tightened, and then the third threaded portion 10 of the inner wall of the nut body 7 clamps the first threaded portion 6, so as to achieve the effect of preventing the nut body 7 from loosening on the surface of the basic body 4.

[0032] In the utility model, when the entire component is installed inside the circular hole 2 opened inside the device body 1, the top end of the basic body 4 can be passed through the circular hole 2 from top to bottom, so that the first threaded portion 6 is located inside the device body 1, and then the nut body 7 is threadedly installed on the surface of the first threaded portion 6, so that the top end of the nut body 7 is tightly abutted against the inner top surface of the device body 1, and as the nut body 7 continues to be tightened on the surface of the first threaded portion 6, the rubber ring 9 is driven to tightly abut against the outer top surface of the device body 1, so that the rubber ring 9 is compressed and deformed, filling the gap between the basic body 4 and the device body 1, thereby forming a structure with a certain sealing performance.

[0033] The rubber ring 9 can increase the friction and shock resistance between the basic body 4 and the device body 1, prevent the nut body 7 from loosening, and thus improve the safety and stability to a certain extent.

[0034] After the nut body 7 is tightened on the surface of the first threaded portion 6, the screw 8 is placed inside the light hole 12, and the screw 8 is threadedly matched with the threaded hole 3, so that the screw 8 can be screwed into the threaded hole 3, thereby driving the upper part 13 and the lower part 14 to be tightened, and then the third threaded portion 10 on the inner wall of the nut body 7 clamps the first threaded portion 6, so as to achieve the effect of preventing the nut body 7 from loosening on the surface of the basic body 4, thereby preventing the nut body 7 from loosening during use, resulting in the installation and sealing of the cable connector being affected.

[0035] 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.
