Description
Technical Field
The invention relates to the technical field of cabin penetrating connectors, in particular to an anti-loosening structure for a cabin penetrating socket installed by a fastening nut.
Background
The cabin penetrating socket is mounted at a cabin plate, and is used for realizing cabin penetrating connection.
The traditional design method for installing the cabin-penetrating socket by the fastening nut has two types:
firstly, equipartition fuse hole on the fastening nut circumference sets up fastening nut's internal thread to left-handed screw simultaneously. The plug is installed in a right-handed mode, the fastening nut of the nut installation cabin penetrating socket is secured with the plug in a matched mode, and therefore the anti-loosening fastening of the connecting component is achieved. And this kind of locking structural design that takes off, the cabin socket is worn in fastening nut installation must be played the insurance with the plug of cooperation installation and just can realize coupling assembling's fastening, if the cabin socket is worn in fastening nut installation is reserve socket, does not have during normal use with it matched with plug, then this cabin socket is worn in nut installation can not realize self-fastening, has not hard up and the risk of deck plate separation.
And secondly, a double-fastening nut structure is adopted, two identical fastening nuts are arranged at the fastening ends of the nut installation cabin penetrating sockets, and looseness prevention is realized by increasing friction force. After the two fastening nuts are screwed up in opposite directions, the nuts are always under the action of additional pressure and friction force, and the friction force still exists when the working load changes, so that the anti-loosening effect is achieved. By adopting the anti-loosening structural design, the tightening torque of the upper nut and the lower nut needs to be accurately controlled in the process of tightening the double nuts. If the moment applied to the upper nut is not enough to overcome the pressure born by the lower nut, the upper nut and the lower nut are just equivalent to one nut, and when alternating load is applied, the friction force between the screw pairs of the double nuts can be reduced or instantly disappears, so that the anti-loosening effect cannot be achieved. Because the screw thread direction is the same, the locking capability cannot be improved by using a fuse to play a fuse between the two nuts. The double nut structure cannot be used in environments where vibration resistance is very demanding.

Compared with the prior art, the invention has obvious advantages and beneficial effects. By means of the technical scheme, the invention can achieve considerable technical progress and practicability, has wide industrial utilization value and at least has the following advantages:
the invention adopts a mode of combining a fastening nut and a stop washer, and radial stop is realized after the flat and inner key structures of the stop washer are matched and assembled in place with the flat structure and the installation key groove of the cabin-penetrating outer shell. And screwing the fastening nut to be attached to the stop gasket, and finally, punching a fuse between the fastening nut and the stop gasket to ensure radial stop of the fastening nut and finally realize fastening and loosening prevention of the socket. According to the invention, through the application of the novel high-reliability fastening anti-loosening structure for the nut installation cabin-penetrating socket, the loosening problem of the fastening nut installation cabin-penetrating socket in a high-vibration environment can be solved, and the connection reliability is ensured.

Detailed Description
To further illustrate the technical means and effects of the present invention adopted to achieve the predetermined objects, the following detailed description will be given to the specific implementation, structure, features and effects of the anti-loosening structure for a fastening nut mounted through-cabin socket according to the present invention with reference to the accompanying drawings and preferred embodiments.
Please refer to fig. 1-4, which are schematic structural views of parts of an anti-loosening structure for a cabin-penetrating socket installed by a fastening nut according to the present invention, the anti-loosening structure includes a stop washer 3 circumferentially and rotatably assembled at the front end of a housing of the cabin-penetrating socket 1, and the stop washer 3 is pressed against an installation cabin plate 2 by the fastening nut 10 screwed on the housing of the cabin-penetrating socket to achieve axial position limitation of the stop washer. The radial stopping between the stopping gasket 3 and the fastening nut 10 is realized through a fuse 9, so that the fastening and the loosening prevention of the socket are realized.
Preferably, the cabin penetrating socket shell and the stop gasket are matched with each other through the concave-convex connection surface to realize circumferential rotation stop.
In the embodiment of the invention, the outer peripheral surface of the front end of the outer shell of the cabin penetrating socket 1 is provided with a concave structure, the stop gasket 3 is internally provided with a convex structure matched with the concave structure, and the concave structure and the convex structure are matched to realize circumferential rotation stop.
Preferably, the outer peripheral surface of the front end of the cabin-penetrating socket outer shell is provided with at least 1 outer peripheral surface flat structure 5 and/or at least one key groove 7, the inner ring of the stop washer 3 is provided with an inner peripheral surface flat structure 4 and/or a corresponding convex key 6, and circumferential rotation stopping of the inner peripheral surface flat structure and the outer peripheral surface flat structure is realized through matching of the inner peripheral surface flat structure and the outer peripheral surface flat structure and/or matching of the convex key and the key groove, but the invention is not limited to this.
