Preferred embodiments of the present utility model will be further elaborated below with reference to the drawings of the present specification.

A locking structure according to an embodiment of the present utility model is described below with reference to fig. 1 to 7.

Referring to fig. 1 to 7, the locking structure 1 includes a supporting block 11, a slider 12, a locking member 14, a first elastic member 13 and a second elastic member 15, where the slider 12 is disposed on the supporting block 11 in a manner of being able to move up and down, the first elastic member 13 is abutted against and connected with the slider 12, and when the slider 12 descends relative to the supporting block 11, the slider 12 elastically deforms the first elastic member 13 to have elastic potential energy, so as to be able to drive the slider to ascend relative to the supporting block 11. The locking piece 14 is movably arranged on the supporting block 11, the locking piece 14 moves relative to the supporting block 11 to have a locking position and an unlocking position, when the sliding block 12 descends, the sliding block 12 is separated from the locking piece 14, and when the sliding block 12 ascends, the sliding block 12 is in linkage connection with the locking piece 14 and drives the locking piece 14 to move from the unlocking position to the locking position; the second elastic member 15 is abutted against and connected with the locking member 14, the elastic force of the second elastic member 15 is used for driving the locking member 14 to return to the unlocking position, and when the locking member 14 moves from the unlocking position to the locking position, the locking member 14 elastically deforms the second elastic member 15.

For example, when the locking piece 14 is at the locking position, the sliding block 12 abuts against the locking piece 14, the sliding block 12 is used for limiting the movement of the locking piece 14 relative to the supporting block 11, at this time, the first elastic piece 13 is in a natural extension state, and the second elastic piece 15 is in a compression deformation state; when an external force capable of enabling the sliding block 12 to move downwards is applied to the sliding block 12, the sliding block 12 descends to enable the sliding block 12 to be separated from the locking piece 14 so as to avoid the locking piece, the locking piece 14 moves relative to the supporting block 11 under the drive of the elastic restoring force of the second elastic piece 15, the locking piece 14 reaches an unlocking position, when the locking piece 14 is in the unlocking position, the second elastic piece 15 is in a natural extension state, and the first elastic piece 13 is in a compression deformation state under the downward pressure of the sliding block 12; when the external force applied to the slider 12 is removed, the slider 12 is reset under the drive of the elastic restoring force of the first elastic member 13, that is, moves upward relative to the supporting block 11, during the process of lifting, the slider 12 abuts against the locking member 14 and applies a force for displacing the locking member 14, the locking member 14 moves from the unlocking position to the locking position, during the process of moving, the locking member 14 presses the second elastic member 15 to elastically deform, and after the first elastic member 13 drives the slider 12 to reset, the slider 12 limits the locking member 14 at the locking position. In this embodiment, the linkage connection is such that the lifting movement of the slider 12 causes a displacement movement of the catch member 14 from the unlocked position to the locked position.

The unlocking and locking of the locking element 14 by the slider 12 can achieve automatic locking and automatic unlocking of the locking element 14 to an object to be locked (the tray will be described below with reference to fig. 8). Specifically, when the locking piece 14 is at the locking position, the sliding block 12 is combined with the locking piece 14, the locking piece 14 is in a locked state, at this time, the locking piece 14 is separated from the object to be locked, when the sliding block 12 descends, the sliding block 12 is separated from the locking piece 14, the locking piece 14 is in an unlocked state, the sliding block 12 releases the locking restriction on the locking piece 14, at this time, the locking piece 14 moves to the unlocking position, in the unlocking position, the locking piece is buckled on the object to be locked, the locking effect of the object to be locked is exerted, and when the sliding block 12 ascends, the sliding block 12 is combined with the locking piece 14 and drives the locking piece 14 to be separated from the object to be locked, and the unlocking effect of the object to be locked is exerted, so that the automatic locking and the automatic unlocking of the object to be locked are realized.

In more detail, the first elastic member 13 and the second elastic member 15 may be springs. It will be appreciated that when the locking member 14 is in the locked position, the first elastic member 13 may be in a moderately compressed deformation state, and may cooperate with a limiting structure (which may be specifically understood by referring to the stop member 19 in fig. 7) to control the stroke range of the lifting movement of the slider 12, and when the slider 12 is lowered, the first elastic member 13 is further compressed and deformed by the downward pressure of the slider 12, so as to form a driving force for driving the slider 12 to move upward. It will be appreciated that when the locking element 14 is in the unlocking position, the second elastic member 15 may be in a moderate compression deformation state, and may cooperate with a limiting structure (which may be specifically understood by referring to the limiting stop 113 in fig. 6) to control the travel range of the displacement movement thereof, and when the slider 12 is lifted, the second elastic member 15 is further compressed and deformed by the pressure of the locking element 14, so as to form a driving force for driving the locking element 14 to move from the locking position to the unlocking position.

Referring to fig. 2, 4 and 5, the slider 12 is provided with a first inclined plane 121, the locking element 14 is provided with a second inclined plane 141, and when the slider 12 is lifted, the first inclined plane 121 abuts against the second inclined plane 141 and slides along the second inclined plane 141, so as to drive the locking element 14 to move from the unlocking position to the locking position.

It will be appreciated that the direction of movement of the displacement movement of catch member 14 between the unlocked and locked positions is perpendicular to the direction of lifting movement of slider 12.

Referring to fig. 1 and 2, the support block 11 is provided with a first guide channel 111 and a second guide channel 112, the guide direction of the first guide channel 111 is perpendicular to the guide direction of the second guide channel 112, the first guide channel 111 and the second guide channel 112 are partially overlapped to be communicated, at least part of the sliding block 12 is slidably connected to the first guide channel 111, at least part of the locking piece 14 is slidably connected to the second guide channel 112, wherein a first inclined surface 121 is arranged on one side, close to the second guide channel 112, of the sliding block 12 located in the first guide channel 111, a second inclined surface 141 is arranged on one side, close to the first guide channel 111, of the locking piece 14 located in the second guide channel 112, and the first inclined surface 121 and the second inclined surface 141 are abutted or separated in an overlapped area of the first guide channel 111 and the second guide channel 112.
