[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present invention pertains. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0034] Embodiment 1

[0035] As Figure 1 -7 shows a locking assembly, including a locking cover 30, a locking member 10, and a first elastic member 20. A locking groove 31 is provided on the locking cover 30. Specifically, one end of the locking member 10 forms a locking end, and the other end of the locking member 10 forms an installation end. The first elastic member 20 is abutted against the installation end, and the first elastic member 20 can provide a first elastic stress. The first elastic stress can drive the installation end to move closer to the locking cover 30, so that the locking end is snapped into the locking groove 31.

[0036] Based on this structure, when using the locking assembly of the present invention, the locking cover 30 and the locking member 10 can be respectively installed on two components to be locked, and the locking member 10 corresponds to the locking groove 31 of the locking cover 30. Under normal circumstances, the first elastic member 20 maintains a normal extended state. The first elastic member 20 can provide a first elastic stress, so that the locking end of the locking member 10 is correspondingly snapped into the locking groove 31 of the locking cover 30 to maintain the locked state. The elastic stress provided by the first elastic member 20 locks the locking end and the locking cover 30, and the locking structure is stable.

[0037] In addition, when unlocking, press the locking member 10, the first elastic member 20 is compressed, and the locking end can be withdrawn from the locking groove 31, and unlocking can be achieved, avoiding wear caused by forced unlocking.

[0038] It should be noted that since the first elastic member 20 provides a driving force for the locking end to move closer to the locking groove 31 of the locking cover 30, even if the locking end is worn, the first elastic stress provided by the first elastic member 20 can compensate for the gap caused by wear, the assembly structure is more stable, and it is not easy to become loose after long-term use.

[0039] Further, a through hole 32 may be provided in the locking groove 31. The through hole 32 can penetrate through both sides of the locking cover 30. When the locking end is snap-fitted into the locking groove 31, the through hole 32 allows an external pressing member to pass through and press the locking end, and the locking end can withdraw from the locking groove 31 to complete the unlocking action.

[0040] More specifically, the locking assembly further includes a pressing member 40 and a second elastic member 50. One end of the pressing member 40 can be inserted into the through hole 32. The end portion inserted into the through hole 32 can be used to press the locking end, while the other end of the pressing member 40 can be used for manual pressing. The second elastic member 50 is clamped between the locking cover 30 and the pressing member 40. The second elastic member 50 can provide a second elastic stress, and the second elastic stress can drive the pressing member 40 away from the locking cover 30.

[0041] When unlocking, the pressing member 40 can be manually pressed. The end portion of the pressing member 40 inserted into the through hole 32 can press the locking end, and the locking end can be pressed to withdraw from the locking groove 31. During this process, both the second elastic member 50 and the first elastic member 20 are compressed to achieve unlocking.

[0042] Of course, in the locked state, the second elastic member 50 remains in the extended state, providing a second elastic stress, so that the end portion of the pressing member 40 is inserted into the through hole 32 and withdraws from the locking groove 31, while the first elastic member 20 can provide a first elastic stress to drive the locking end to be snap-fitted in the locking groove 31 to maintain the locked state.

[0043] In addition, in the absence of the through hole 32 and the pressing member 40, one of the components to be locked can also be directly moved. Due to the presence of the first elastic member 20, the mutual force between the two components can cause the first elastic member 20 to be compressed, and the locking end can withdraw from the locking groove 31, and unlocking can also be achieved.

[0044] Specifically, a through post can be provided at the end portion of the pressing member 40. The through post can be inserted into the through hole 32 to facilitate assembly. The portion of the end portion of the pressing member 40 away from the through end can be an arc-shaped piece to facilitate manual pressing.

[0045] It should be noted that the pressing member 40 can be implemented by using a button structure in the prior art. In addition, in this embodiment, the first elastic member 20 and the second elastic member 50 can both be implemented by using a spring in the prior art. In other cases, the first elastic member 20 and the second elastic member 50 can also be made of other self-resetting materials such as elastic rubber blocks in the prior art.

[0046] Further, a buckle 11 can be provided at the installation end. The buckle 11 can assemble the locking member 10 on the component to be locked to facilitate disassembly and assembly.

[0047] Of course, it is also possible to directly insert and install the active mounting end onto the structure to be locked, and then correspondingly set a limit buckle on the structure to be locked to prevent the mounting end from detaching from the structure to be locked, which is also convenient for assembly.

[0048] Embodiment 2

[0049] Such as Figure 1 As shown in FIG. -7, a handle locking structure includes a handle 60, a housing 70, and a locking assembly. The locking assembly includes a locking cover 30, a locking member 10, and a first elastic member 20. The locking cover 30 is installed at the bottom end of the handle 60, and a locking groove 31 is provided on the locking cover 30. The locking member 10 is installed on the housing 70. Specifically, one end of the locking member 10 forms a locking end, and the other end of the locking member 10 forms a mounting end. The first elastic member 20 is abutted against the mounting end, and the first elastic member 20 can provide a first elastic stress. The first elastic stress can drive the mounting end to move closer to the locking cover 30 so that the locking end is snapped into the locking groove 31.

[0050] Based on the above structure, when using the handle locking structure of the present invention, the locking cover 30 can be assembled at the bottom end of the handle 60, and the locking member 10 and the first elastic member 20 are installed on the housing 70. When locking the handle 60 and the housing 70, the locking cover 30 on the handle 60 can correspond to the locking member 10 of the housing 70. Through the locking of the locking cover 30 and the locking member 10, the handle 60 can be locked on the housing 70 or the box body. When the user lifts the handle 60, the housing 70 or the box body can be taken away, reducing the complicated operation and misoperation of the user.

[0051] It should be noted that the above housing can be the box body of a lunch box, the box body of a thermal insulation box, the cup body of a cup, or the box body of a storage box, or a basket, etc. In short, any structure with a handle can be applied.

[0052] Specifically, the handle 60 is directly combined with the cover body through a hook or a screw, and the handle 60 can rotate freely. When combined with the housing 70, the cover body covers the housing 70. As long as the handle 60 is lifted, the locking end on the housing 70 can, under the action of the first elastic member 20, correspond to the locking groove 31 on the handle 60. The first elastic stress can keep it in a state of being snapped into the locking groove 31 to achieve locking, and the locking structure is stable. When removing the cover body, by pressing the above-mentioned locking end, the first elastic member 20 can be compressed to achieve unlocking.

[0053] Of course, the handle 60 can also be directly combined with the housing 70 without using the cover body structure.

[0054] More specifically, a guiding groove 33 may be provided on the locking cover 30. One end of the guiding groove 33 penetrates into the locking groove 31, and the other end of the guiding groove 33 penetrates to the edge of the locking cover 30. The guiding groove 33 can guide the locking end to slide into the locking groove 31.

[0055] When the handle 60 is assembled with the housing 70, the locking end on the housing 70 can correspond to the guiding groove 33 under the action of the first elastic member 20. The locking end can slide along the guiding groove 33 under the action of the first elastic stress and gradually slide into the locking groove 31, and is clamped with the locking groove 31 to achieve locking, and the locking structure is stable.

[0056] When removing the cover body, by pressing the above-mentioned locking end, the first elastic member 20 can be compressed, and then the handle 60 is toggled to make the locking end slide out along the guiding groove 33 to achieve unlocking.

[0057] It should be noted that due to the existence of the guiding groove 33, the locking end of the locking member 10 can correspond to the edge position of the locking cover 30, without corresponding to the middle of the locking cover 30. By rotating the handle 60, the locking end corresponding to the guiding groove 33 can achieve locking and unlocking. Compared with setting the card slot in the middle, by setting the structure extending to the edge of the locking cover 30, without pulling the handle 60, the locking and unlocking operations are more convenient.

[0058] Furthermore, a through hole 32 may be provided in the locking groove 31. The through hole 32 can penetrate to both sides of the locking cover 30. When the locking end is clamped into the locking groove 31, the through hole 32 can allow an external pressing member to pass through and press the locking end, and the locking end can withdraw from the locking groove 31 to complete the unlocking action.

[0059] More specifically, the locking assembly further includes a pressing member 40 and a second elastic member 50. One end of the pressing member 40 can penetrate into the through hole 32. The end portion penetrating into the through hole 32 can be used to press the locking end, and the other end of the pressing member 40 can be used for manual pressing. The above-mentioned second elastic member 50 is clamped between the locking cover 30 and the pressing member 40. The second elastic member 50 can provide a second elastic stress, and the second elastic stress can drive the pressing member 40 away from the locking cover 30.

[0060] When unlocking, the above-mentioned pressing member 40 can be manually pressed. The end portion of the pressing member 40 penetrating into the through hole 32 can press the locking end, and the locking end can be pressed to withdraw from the locking groove 31. In this process, both the second elastic member 50 and the first elastic member 20 are compressed to achieve unlocking.

[0061] Of course, in the locked state, the second elastic member 50 remains in the extended state, providing a second elastic stress, causing the end of the pressing member 40 to pass through the through-hole 32 and withdraw from the locking groove 31, while the first elastic member 20 can provide a first elastic stress to drive the locking end to be clamped in the locking groove 31 to maintain the locked state.

[0062] In addition, in the absence of the through-hole 32 and the pressing member 40 described above, one of the components to be locked can also be directly moved. Due to the presence of the first elastic member 20, the mutual force between the two components can cause the first elastic member 20 to be compressed, and the locking end can withdraw from the locking groove 31, and unlocking can also be achieved.

[0063] Based on the above structure, unlocking can be achieved by pressing the pressing member 40, and unlocking can be performed by pressing on the outer side of the handle 60, which is more convenient to operate.

[0064] Specifically, a through-column can be provided at the end of the pressing member 40, and the through-column can pass through the through-hole 32 to facilitate assembly. The part of the end of the pressing member 40 away from the through-end can be an arc-shaped piece to facilitate manual pressing.

[0065] It should be noted that the pressing member 40 can be selected as a button structure in the prior art to implement. In addition, in this embodiment, the first elastic member 20 and the second elastic member 50 can both be selected as springs in the prior art. In other cases, the first elastic member 20 and the second elastic member 50 can also be made of other self-resetting materials such as elastic rubber blocks in the prior art.

[0066] Furthermore, a buckle 11 is provided at the installation end, and a card slot is correspondingly provided on the housing 70. One end of the first elastic member 20 passes through the card slot, and the other end of the first elastic member 20 abuts against the installation end; the buckle 11 is movably clamped into the card slot. In this way, when the locking member 10 is assembled to the housing 70, the buckle 11 on the locking member 10 can movably pass through the card slot, and the first elastic member 20 can also be assembled in the card slot. The buckle 11 on the locking member 10 can abut against the outer side wall of the card slot under the action of the first elastic member 20 to prevent the locking member 10 from disengaging from the card slot. At the same time, the buckle 11 can move in the card slot when the locking member 10 is pressed, facilitating locking and unlocking, and making disassembly and assembly more convenient.

[0067] Of course, it is also possible to directly insert the installation end movably onto the card slot, that is, the installation end and the housing are slidably matched in an inserted manner. Then a limit buckle is provided at the outlet position of the card slot to prevent the installation end from disengaging from the card slot structure, which is also convenient for assembly.

[0068] Embodiment 3

[0069] An electric rice box includes the handle locking structure in Embodiment 2, and the housing 70 is formed as the box body of the electric rice box; a heating component is provided inside the housing 70, that is, the handle locking structure in Embodiment 2 can be applied to the electric rice box.

[0070] Specifically, the handle 60 is directly combined with the lid body by a hook or a screw, and the handle 60 can rotate freely. When combined with the box body, the lid body covers the box body. As long as the handle 60 is lifted, the locking end on the box body can, under the action of the first elastic member 20, correspond to the locking groove 31 in the handle 60, and the first elastic stress can keep it in a state of being clamped in the locking groove 31 to achieve locking, and the locking structure is stable. When removing the lid body, by pressing the above-mentioned locking end, the first elastic member 20 can be compressed to achieve unlocking.

[0071] Of course, the handle 60 can also be directly combined with the box body without using the lid body structure.

[0072] It should be noted that the above-mentioned heating component can be installed at the bottom end of the box body, and the heating component can directly heat the food in the box body. In addition, the power cord of the heating component can be led out from the outside of the box body and electrically connected to the external mains supply.

[0073] Of course, the above-mentioned heating component can be selected from structures such as resistors or heating plates in the prior art to achieve.

[0074] For those skilled in the art, various corresponding changes and deformations can be made according to the technical solutions and concepts described above, and all these changes and deformations should fall within the protection scope of the claims of the present invention.
