Detailed Description

The present invention will be further described with reference to the following detailed description of preferred embodiments thereof, which is to be read in connection with the accompanying drawings.

First, a nut anti-loosening structure according to an embodiment of the present invention will be described with reference to fig. 1 to 4, which is used for loosening prevention when a nut is connected, and the application scenario is wide.

As shown in fig. 1 to 4, the nut anti-loosening structure according to the embodiment of the present invention includes a nut main body 1, at least one anti-loosening tooth 2, a shielding layer 3, an anti-loosening ring gear 4, and a pin carrier 5.

Specifically, as shown in fig. 1 to 2 and 4, an internal thread 11 is provided on an inner wall of the nut main body 1, the internal thread 11 is used for connecting with an external thread of an external plug connector, a limiting edge 12 is provided at one end of the inner wall of the nut main body 1, and the limiting edge 12 is used for limiting when the shielding layer 3 is installed.

Specifically, as shown in fig. 1 to 2 and 4, at least one locking tooth 2 is arranged on the limiting edge 12 for playing a locking role.

Specifically, as shown in fig. 1 and 3 to 4, the shielding layer 3 is inserted on the nut body 1 for preventing signal interference.

Specifically, as shown in fig. 1 and 3 to 4, the locking gear ring 4 is sleeved at the end of the shielding layer 3, and the locking gear ring 4 is in contact with the plurality of locking teeth 2. Locking ring gear 4 comprises a plurality of teeth 41, the inclination of the first inclined plane 42 of tooth 41 and locking tooth 2 contact is greater than the inclination of the second inclined plane 42 of tooth 41 and locking tooth 2 contact, when nut main part 1 is screwed up clockwise, second inclined plane 42 contacts with locking tooth 2 on the nut main part 1 this moment, because the inclination of second inclined plane 42 is great, be convenient for screw up of nut main part 1, when nut main part 1 is unscrewed anticlockwise, first contact surface contacts with locking tooth 43 on the nut main part 1 this moment, because the inclination of first inclined plane 43 is less, difficult the twisting, thereby play locking effect.

Specifically, as shown in fig. 1 and 4, a pin carrier 5 is inserted in the shielding layer 3 for placing the connecting wires and the conductive pins.

Further, as shown in fig. 1 to 2, in the embodiment, the number of the locking teeth 2 may be three, and the locking teeth 2 are uniformly arranged on the limiting edge 12 around the axial center line of the nut body 1, so that the material processing cost can be saved on the premise of ensuring the locking effect.

Further, as shown in fig. 1 to 2 and 4, the nut body 1 is a hexagon nut, so that the nut body 1 can be conveniently installed, and can be tightened by using a conventional hexagon wrench, and installation in a narrow space can be realized.

Further, as shown in fig. 1 and 4, the axial center lines of the nut body 1, the shielding layer 3 and the pin carrier 5 are on the same straight line, so that the stability during installation is ensured.

Further, as shown in fig. 1 and 3 to 4, the lock ring gear 4 and the shielding layer 3 are integrally formed, so that the overall strength is improved.

When in use, the pin carrier 5, the shielding layer 3 and the nut body 1 are sequentially connected with each other, and then are screwed with an external plug connector through the internal thread 11 of the nut body 1.
