[0035] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0036] The present invention provides an adaptive quick-locking plug-in / disconnection assist device, which comprises a screw assembly, a rotating shaft assembly, a connecting rod 1, a lifting handle 3, and a hook claw 4.

[0037] There are two sets of rotating shaft components and hook claws respectively. The hook claw 4 is connected to the connecting rod 1 through the rotating component, and the hook claw 4 can move horizontally relative to the connecting rod 1 through the rotating component.

[0038] Screw components such as Figure 2 , Figure 3 As shown, it includes a screw rod 5, a lever 6, a spring pressure plate 7, a locking spring 8, a rotating washer 9, a rotating head 10 and a limiting pin 11.

[0039] The screw rod 5 is connected to the connecting rod 1 by a thread. By rotating the screw rod 5, it can move up and down linearly relative to the connecting rod 1, thereby realizing the pressing operation of the separation connector. The lever 6 passes through the through hole at the top of the screw rod 5 and is connected thereto, and can move linearly along the through hole relative to the screw rod 5. The spring pressure plate 7 is connected to the screw rod 5 by a thread. By rotating the spring pressure plate 7, it can move along the thread on the screw rod 5. Figure 1 The locking spring 8 passes through the screw rod 5 and is sandwiched between the spring pressing piece 7 and the lifting handle 3. The spring pressing piece 7 and the locking spring 8 cooperate with each other to apply a force to the lifting handle 3. Figure 1 The downward pressure shown in the figure can automatically reset the handle 3 when the lifting handle 3 is released. The downward pressure can be adjusted by rotating the spring pressure plate 7. There are two rotating washers 9 installed at the bottom of the screw 5 and can rotate freely. The rotating head 10 is installed below the rotating washer 9 and is only suspended on the surface of the screw, but not fixed to the screw. When the screw 5 is pressed down, the rotating head 10 will not rotate with the screw 5 under the action of the rotating washer, so as to prevent scratching the connector surface. The limit pin 11 is fixedly connected to the screw 5, and through cooperation with the shoulder of the screw 5, it limits the up and down movement of the rotating washer 9 and the rotating head 10 without affecting their rotation.

[0040] Rotating components such as Figure 2 As shown, it includes a rotating shaft 2, a sleeve 12 and a plug 13. The sleeve 12 is connected to the hook 4 and the connecting rod 1. The rotating shaft 2 is connected to the sleeve 12. The plug 13 is fixedly connected to the rotating shaft 2.

[0041] The lifting handle 3 is connected to the screw rod 5 , and the screw rod 5 passes through a through hole on the lifting handle 3 , so that the lifting handle 3 can move linearly along the screw rod 5 .

[0042] The lifting handle 3 is connected to the hook 4, and the hook 4 passes through the through slot of the lifting handle 3, limiting the rotation of the lifting handle 3 so that it can only move up and down. At the same time, when the lifting handle 3 is moved, the left and right hooks can move in opposite directions under the restriction of the through slot, and the two hooks can cooperate to form two states of opening and closing.

[0043] The method of using the device to assist is:

[0044] While holding the connecting rod 1 with your palm, pull the lifting handle 3 with your fingers, so that the lifting handle 3 moves Figure 1 At this time, the internal groove of the lifting handle 3 presses against the inner side of the hook 4. Since the angle formed by the hooks 4 on both sides is an obtuse angle in the initial state, as the lifting handle 3 moves upward, the two hooks 4 move in opposite directions around the rotating shaft 2, and the angle between the two hooks 4 gradually increases until the distance between the two hooks 4 is enough to clamp the separation connector, and then the lifting handle is released. At this time, under the action of the locking spring 8, the lifting handle 3 automatically moves to Figure 1 As shown, the lower part is reset, and at the same time, under the limit of the internal slot of the lifting handle 3, the angle formed by the hook claws 4 on both sides gradually decreases until the hook claws 4 clamp the connector, and the lifting handle 3 stops resetting. At this time, the bend below the hook claw 4 clamps the connector flange, and the connector body is clamped into the V-shaped notch below the hook claw 4, so that the center of the connector is automatically aligned with the upper screw 5. The spring pressing piece can be turned clockwise to compress the locking spring 8, thereby increasing the clamping force of the hook claw 4.

[0045] When the hook 4 clamps the connector, hold the lever 6 and turn the screw 5 clockwise until the rotating head 10 below the screw 5 presses against the top of the separation connector, and continue to turn the screw 5. The separation connector is pressed downward by the screw 5. At the same time, the hooks 4 on both sides press against the connector flange, and the lifting handle 3 remains motionless under the action of the locking spring 8. The entire device is in a locked state to ensure that the connector does not move. When the screw 5 presses the separation connector downward, the screw shoulder presses the rotating washer 9 below, and the pressure is transmitted to the rotating head 10 through the two layers of rotating washers 9, thereby pressing down the separation connector. Since the downward pressure of the screw is indirectly transmitted to the rotating head 10 through the rotating washer 9, the rotating head 10 will not rotate with the screw 5, and the rotating head 10 and the connector are relatively stationary.

[0046] When the screw rod 5 rotates to a suitable position, the separation connector is pressed down. At this time, the present invention is in a locked state as a whole. The pressed state remains unchanged, and the test plug can be freely plugged in and out. After the test is completed, the lifting handle 3 is pulled upward. Under the action of the internal groove of the lifting handle 3, the claws 4 on both sides open, and the device is no longer locked. After taking out the separation connector, the lifting handle automatically resets under the action of the spring 8, and a new round of testing can be carried out.

[0047] The above-described embodiments are only preferred specific implementations of the present invention. Common changes and substitutions made by those skilled in the art within the scope of the technical solution of the present invention should be included in the protection scope of the present invention.
