Abstract

A lock structure and a cooking appliance are provided. The lock structure has a fixing member and a locking assembly. The locking assembly has a bearing member, a mount connected to the bearing member, a driving member, a first elastic member and a locking member. The bearing member is detachably connected to a surface. At least a portion of the driving member is provided within the mount. A first end of the first elastic member is connected to the driving member. The locking member is connected to a second end of the first elastic member. The locking member is capable of moving relative to the mount under the driving of the driving member and the first elastic member, and is locked to or separated from the fixing member.

First claim

What is claimed is:

1 . A lock structure comprising:
a fixing member; and a locking assembly comprising:
a bearing member detachably connected to a mounting surface;
a mount connected to the bearing member;
a driving member, at least a portion of the driving member being provided within the mount;
a first elastic member, a first end of the first elastic member being connected to the driving member; and
a locking member connected to a second end of the first elastic member, wherein the locking member is capable of moving relative to the mount under the driving of the driving member and the first elastic member and is locked to or separated from the fixing member.

2 . The lock structure according to claim 1 , wherein the bearing member comprises:
a mounting portion provided with a first opening, wherein the mounting portion comprises a first side surface, and the first side surface is used for detachably connecting with the mounting surface; and a bearing portion, wherein a first end of the bearing portion is connected to the first side face, the bearing portion is provided with a second opening and a receiving portion in communication, the second opening is located at a second end of the bearing portion, the mount extends into the receiving portion via the first opening, and the locking member is capable of moving relative to the second opening and being locked to or separated from the fixing member.

3 . The lock structure according to claim 2 , wherein:
the mounting portion extends out of the circumferential edge of the bearing portion, and the mounting portion extending out of the circumferential edge of the bearing portion is configured to abut against the mounting surface.

4 . The lock structure according to claim 2 , wherein the mount is detachably connected to the bearing portion.

5 . The lock structure according to claim 2 , wherein the bearing member further comprises a baffle connected to the bearing portion, wherein the baffle is capable of sliding within the accommodating portion to push the locking member.

6 . The lock structure according to claim 1 , wherein the locking assembly further comprises a guide structure provided on the mount, wherein at least a portion of the driving member is movable along with the guide structure and restrained at an end of the guide structure.

7 . The lock structure according to claim 6 , wherein the driving member comprises:
a pressing member penetrating the mount and movably connected to the mount, wherein the pressing member comprises a first inclined surface; and a moving member slidingly connected to the guide structure, the moving member being connected to a first end of the first elastic member, the moving member being capable of being restrained to an end portion of the guide structure, wherein the moving member comprises a second inclined surface, and the first inclined surface is configured to abut against the second inclined surface, so as to drive the moving member to drive the locking member to switch the station.

8 . The lock structure according to claim 7 , wherein:
the moving member comprises a sliding jaw sleeve, a sidewall of the sliding jaw sleeve is provided with a first protruding portion, wherein the first protruding portion is slidably connected to the guide structure and is configured to abut against the end portion of the guide structure, and the second inclined surface is provided on the first protruding portion.

9 . The lock structure according to claim 1 , wherein the locking assembly further comprises a driving inclined surface abutting against a fixing member to drive the locking member to move relative to the mount.

10 . The lock structure according to claim 1 , wherein the locking assembly further comprises a second elastic member provided in the mount and connected to the driving member and the mount for moving the locking member back,
wherein at least a part of the first elastic member is located inside the locking member, and the second elastic member is sleeved on the locking member.

11 . A cooking appliance comprising:
a cavity body assembly; a door body assembly in an open-close connection with the cavity body assembly; and the lock structure according to claim 1 , wherein the fixing member is provided in one of the cavity body assembly and the door body assembly, and the locking assembly is provided in the other of the cavity body assembly and the door body assembly.

12 . The cooking appliance according to claim 11 , wherein the cavity body assembly comprises:
