Of course, in the locked state, the second elastic member 50 is kept in the extended state to provide the second elastic stress, so that the end of the pressing member 40 penetrates through the through hole 32 and exits from the locking groove 31, and the first elastic member 20 provides the first elastic stress to drive the locking end to be snapped into the locking groove 31, so as to keep the locked state.

In addition, in the case of not having the through hole 32 and the pressing piece 40, one of the members to be locked may be directly moved, and due to the existence of the first elastic member 20, the interaction force between the two members may cause the first elastic member 20 to be compressed, and the locking end may be withdrawn from the locking groove 31, and the unlocking may also be achieved.

Specifically, a through-connection column can be further arranged at the end of the pressing piece 40, and the through-connection column can be penetrated into the through-connection hole 32, so that the assembly is facilitated. The part of the end of the pressing piece 40 far away from the penetrating end can be a circular arc piece, so that the pressing piece can be pressed by hands conveniently.

It should be noted that the pressing member 40 may be implemented as a button structure in the prior art. In addition, in the present embodiment, the first elastic member 20 and the second elastic member 50 may be implemented by using springs in the prior art, and in other cases, the first elastic member 20 and the second elastic member 50 may also be made of other materials capable of self-restoring, such as elastic rubber blocks in the prior art.

Further, a buckle 11 can be arranged at the mounting end, and the buckle 11 can assemble the locking piece 10 on the part to be locked, so that the assembly and disassembly are convenient.

Of course, the mounting end can also be movably inserted to the structure to be locked, and then the limiting buckle is correspondingly arranged on the structure to be locked, so that the mounting end is prevented from being separated from the structure to be locked, and the assembly is also convenient.

In the case of the example 2, the following examples are given,

a handle locking structure as shown in fig. 1-7, comprising a handle 60, a housing 70 and a locking assembly, wherein the locking assembly comprises a locking cover 30, a locking piece 10 and a first elastic member 20, the locking cover 30 is mounted at the bottom end of the handle 60, the locking cover 30 is provided with a locking groove 31, the locking piece 10 is mounted on the housing 70, one end of the locking piece 10 is formed as a locking end, the other end of the locking piece 10 is formed as a mounting end, the first elastic member 20 abuts against the mounting end, the first elastic member 20 can provide a first elastic stress, and the first elastic stress can drive the mounting end to move close to the locking cover 30, so that the locking end is clamped to the locking groove 31.

On the basis of the structure, when the handle locking structure is used, the locking cover 30 can be assembled at the bottom end of the handle 60, the locking piece 10 and the first elastic part 20 are installed on the shell 70, when the handle 60 and the shell 70 are locked, the locking cover 30 on the handle 60 can correspond to the locking piece 10 of the shell 70, the handle 60 can be locked on the shell 70 or the box body through the locking of the locking cover 30 and the locking piece 10, a user can take away the shell 70 or the box body by lifting the handle 60, and the complex operation and misoperation of the user are reduced.

The shell can be a box body of a lunch box, a box body of a heat preservation box, a cup body of a cup, a box body of a storage box, a basket and the like, and the structure with the handle can be applied.

Specifically, handle 60 directly combines together through trip or screw and lid, and handle 60 can freely rotate, and when combining with casing 70, the lid closes on casing 70, as long as lift handle 60, and the locking end on casing 70 can be under the effect of first elastomeric element 20, and the correspondence is in handle 60's locking groove 31, and first elastic stress can make its state that keeps the joint at locking groove 31, realizes the locking, and locking structure is stable. When the cover is removed, the first elastic member 20 may be compressed by pressing the locking end, thereby unlocking the cover.

Of course, handle 60 may also be directly coupled to housing 70 without the use of a cover structure.

More specifically, the locking cover 30 may be provided with a guide groove 33, one end of the guide groove 33 may be penetrated into the locking groove 31, and the other end of the guide groove 33 may be penetrated into the edge of the locking cover 30, and the guide groove 33 may guide the locking end to slide into the locking groove 31.

When handle 60 and casing 70 assemble, the locking end on casing 70 can be under the effect of first elastic component 20, corresponding to guide way 33, and the locking end can slide along guide way 33 under the effect of first elastic stress to progressively slide into locking groove 31, with locking groove 31 joint, realize the locking, locking stable in structure.

When the cover body is taken down, the first elastic part 20 can be compressed by pressing the locking end, and then the handle 60 is pulled, so that the locking end slides out along the guide groove 33 to realize unlocking.

It should be noted that, due to the existence of the guide groove 33, the locking end of the locking element 10 may be located at the edge of the locking cover 30, and the locking and unlocking can be achieved without rotating the handle 60 and the locking end corresponding to the guide groove 33, corresponding to the middle of the locking cover 30. For the draw-in groove setting in the middle part, through setting up the structure that extends to the border of locking lid 30, need not to stimulate handle 60, locking and unblock operation are more convenient.

On the basis of the structure, the unlocking is realized by pressing the pressing piece 40, the unlocking can be pressed outside the handle 60, and the operation is more convenient.

Specifically, a through-connection column may be further disposed at an end of the pressing member 40, and the through-connection column may be penetrated into the through-connection hole 32, so as to facilitate assembly. The part of the end of the pressing piece 40 far away from the penetrating end can be a circular arc piece, so that the pressing piece can be pressed by hands conveniently.
