The terms "vertical," "horizontal," "left," "right," and the like are used herein for illustrative purposes only.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this utility model belongs. The terminology used in the description of the utility model herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model. The term "and/or" as used in this specification includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1, in a first aspect, the present utility model provides an unlocking structure 10, comprising: housing 100, spindle 200, knob 400, and lock cylinder 500.

The case 100 may be formed in a regular shape such as a rectangular parallelepiped or a square, or the case 100 may be formed in an irregular three-dimensional shape. The housing 100 has an accommodating space therein, the housing 100 is provided with a through hole 110, and the through hole 110 can communicate the accommodating space with the outside of the housing 100. Of course, the housing 100 may be implemented as any other suitable shape or configuration of the housing 100, as desired.

Referring to fig. 2-3, the housing 100 is illustratively provided with a mounting plate with the through-hole 110 disposed therein.

For the above-mentioned rotation shaft 200, it is coupled with the through hole 110 in a matching manner. Illustratively, the rotary shaft 200 passes through the through hole 110 and is limitedly connected with the mounting plate along the axial direction of the rotary shaft 200 to prevent the rotary shaft 200 from moving in the axial direction.

When the rotation shaft 200 receives a force in the circumferential direction of the rotation shaft 200, the rotation shaft 200 can rotate within the through hole 110. The rotating shaft 200 is provided with a first connection portion 210. Specifically, along the axial direction of the rotating shaft 200, the rotating shaft 200 includes a first end and a second end, and the first connection portion 210 is disposed at the first end of the rotating shaft 200.

Specifically, the force along the axial direction of the rotation shaft 200 may be directed toward the housing or away from the housing, and when the force is directed toward the housing, the knob 400 moves toward the housing, and when the force is directed away from the housing, the knob 400 moves away from the housing.

When subjected to torque in the circumferential direction of the rotary shaft 200: if the knob 400 is at the first position, the knob 400 can transmit torque to the rotating shaft 200 to rotate the rotating shaft 200 because the second connecting portion 410 is in matching connection with the first connecting portion 210; if the knob 400 is at the second position, the second connecting portion 410 is separated from the first connecting portion 210, so that the knob 400 cannot transmit torque to the rotation shaft 200, and the rotation shaft 200 cannot rotate.

It will be appreciated that, along the axial direction of the shaft 200, the first connection portion 210 and the second connection portion 410 may be partially or completely connected, so that the first position does not refer to a certain position alone, and the first position refers to: when the first connecting portion 210 is partially connected to the second connecting portion 410 and is completely connected to the second connecting portion 410, the knob 400 is integrated at all positions. Similarly, the second position refers to: the first connection portion 210 and the second connection portion 410 are disconnected from each other, and the knob 400 is positioned in a combined manner.

The lock cylinder 500 is connected to the second end of the rotary shaft 200. When the rotating shaft 200 rotates, the rotating shaft 200 drives the lock cylinder 500 to move, so as to realize unlocking or locking operation, and it should be noted that the unlocking or locking operation can control the rotating shaft 200 to rotate along two opposite directions for implementation, and the disclosure of the present application should not be understood as insufficient with reference to the prior art.
