Unlocking of the plug 1 and the receptacle 2 is caused by axial displacement of the unlocking member 20 in the unlocking direction (rearward), causing the locking claws 30 to rotate about the fulcrum. In the unlocking process of the plug 1 and the socket 2, the unlocking component axially moves in the unlocking direction, the main unlocking wedge 21 on the unlocking component can generate acting force which is perpendicular to the inclined planes of the two wedges on the auxiliary unlocking wedge 31 on the locking claw 30, the locking claw rotates around the pin 4 through the lever principle, the front end of the locking claw 30 is lifted upwards to be separated from the locking groove, then the unlocking component is pulled continuously, the rear end of the unlocking component abuts against the stopping flange 5 and applies acting force to the plug in the backward direction, and the plug is pulled out from the socket at one time. It should be noted here that when the unlocking sleeve is pulled to move backward until it abuts against the stop flange, the main unlocking wedge 21 is located on the front side of the secondary unlocking wedge 31 and does not slide backward beyond the secondary unlocking wedge.
Through the introduction of the push-pull locking connecting assembly, the locking claw utilizes the lever principle, can conveniently realize the locking and plugging of the plug and the socket, can realize the unlocking and the pulling-out of the plug and the socket only through the simple axial movement of the unlocking part, and is very simple and convenient to operate; in addition, the short axial unlocking distance can reduce the overall size of the assembly, and is beneficial to the development of the assembly towards miniaturization; and utilize lever principle unblock and prior art can improve the mechanical life of subassembly locking mechanism moreover.

In the second embodiment, as shown in fig. 8, unlike the first embodiment, the locking claw and the pin of the cylindrical housing may be integrally formed, and the spring may be removed, so that the locking and unlocking may be performed by the elastic deformation of the claw itself. The two sides of the locking claw in the width direction are connected with the groove wall through a torsion bar 14, and the torsion bar 14 is a structure which can be screwed around the axis of the torsion bar 14 to generate elastic deformation. When the locking claw is inserted, under the interaction of the claw guide inclined plane and the operation guide inclined plane, the locking claw is enabled to swing around the torsion bar, so that the claw at the front end of the locking claw slides into the locking groove, and when the locking claw is unlocked, the locking claw swings around the torsion bar 14 under the action of the unlocking sleeve, so that the front end of the locking claw is lifted upwards and separated from the locking groove to complete unlocking.
In the third embodiment, as shown in fig. 9, unlike the second embodiment, the limit projection 13 on the cylindrical base may be arranged on the outer side surface of the locking pawl, and accordingly, the limit projection 22 on the unlocking sleeve is arranged at a position corresponding to the limit projection 13.
In the fourth embodiment, as shown in fig. 10, the front end of the locking claw has two claws unlike the first embodiment, but of course, in other embodiments, the number of the claws may be three or more.
In the fifth embodiment, as shown in fig. 11, different from the first embodiment, other forms of springs may be used to provide the locking claw with the elastic force, and the springs are changed to torsion springs, the torsion springs 71 are installed at the rotation shaft positions of the locking claws, and the elastic force-applying ends are applied to the rear ends of the locking claws.
For another example, in another embodiment, different from the first embodiment, the unlocking member is an unlocking piece, and two unlocking pieces are provided, and are respectively slidably and slidably mounted on groove walls of the two groove structures in the front-rear direction to cover the locking connection structure, and apply an acting force to the locking claw by pushing the mating structure in the process of backward sliding, and enable the locking claw to swing to the unlocking state. Of course, in other embodiments, there is only one locking connection structure, and correspondingly, only one unlocking tab; or when the unlocking sleeve is used as the unlocking component, only one pushing matching structure corresponding to the locking connection structure is arranged in the unlocking sleeve.
Or in other embodiments, different from the first embodiment, one of the master unlocking wedge block and the slave unlocking wedge block is a common rectangular bump, or one of the master unlocking wedge block and the slave unlocking wedge block is a hemispherical block; the anti-disengaging structure for stopping the unlocking sleeve can comprise a stopping flange and a C-shaped clamping ring positioned on the front side of the stopping flange, the peripheral surface of the front end of the cylindrical shell is provided with a clamping groove, and the clamping ring is clamped in the clamping groove and can be used for preventing and stopping the unlocking sleeve on the front side.
For another example, in another embodiment, different from the above-mentioned embodiment, the locking structure provided on the socket plugging end is a hook protruding from the cylindrical thin-walled structure, and the claw at the front end of the locking claw for engaging with the claw is a hook-and-loop structure.
The specific structure of the embodiment of the push-pull locking plug of the present invention is the same as the structure of the plug in the embodiment of the push-pull locking connection assembly described above, and the detailed description thereof is omitted.
The above description is only a preferred embodiment of the present invention, and not intended to limit the present invention, the scope of the present invention is defined by the appended claims, and all structural changes that can be made by using the contents of the description and the drawings of the present invention are intended to be embraced therein.
