[0064] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0065] It should be noted that when a component is referred to as being "mounted on" another component, it may be directly on the other component or there may be a central component. When a component is considered to be "set on" another component, it may be directly set on the other component or there may be a central component at the same time.

[0066] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art to which the present application belongs. The terms used herein in the specification of the present application are only for the purpose of describing specific embodiments and are not intended to limit the present application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0067] Some embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0068] Please also read Figure 1 , Figure 2 and Figure 3 The locking assembly 100 provided in the embodiment of the present application includes a base 10, a first locking component 20 and a second locking component 30. The bottom wall of the first locking component 20 is installed on the base 10, and a protrusion 21 is convexly provided on the side wall where the first locking component 20 is connected to the base 10.

[0069] The second locking member 30 includes a fixing portion 31, a clamping portion 32 rotatably connected to the fixing portion 31, and an elastic portion 33 abutting between the fixing portion 31 and the clamping portion 32. The fixing portion 31 is configured to abut the first locking member 20, and the fixing portion 31 is provided with a receiving groove 311. The clamping portion 32 includes a connecting end 321, and a first clamping end 322 and a second clamping end 323 extending from different directions of the connecting end 321, respectively. The connecting end 321 and the fixing portion 31 are rotatably connected, the first clamping end 322 is provided in the receiving groove 311, and the elastic portion 33 is elastically abutted between the fixing portion 31 and the first clamping end 322. A clamping groove 3231 is provided at one end of the second clamping end 323 away from the first clamping end 322. The first clamping end 322 is configured to push the clamping groove 3231 on the second clamping end 323 to clamp the protrusion 21 under the elastic force of the elastic portion 33.

[0070] In the above-mentioned lock assembly 100, when the lock assembly 100 needs to be locked, the fixing portion 31 is placed on the first lock member 20, and the user drives the second clamping end 323 to rotate relative to the fixing portion 31 with one hand, so that the clamping groove 3231 on the second clamping end 323 clamps the protrusion 21 on the first lock member 20. When the lock assembly 100 needs to be opened, the user drives the first clamping end 322 to rotate relative to the fixing portion 31 with one hand and applies pressure to the elastic portion 33. At this time, the second clamping end 323 rotates with the first clamping end 322 and separates from the fixing portion 31, so that the protrusion 21 can be separated from the clamping groove 3231 on the second clamping end 323, so that the user can lock or open the lock assembly 100 with one hand, thereby improving the convenience of using the lock assembly 100.

[0071] It is understandable that the first locking member 20 and the second locking member 30 can be respectively connected to two elements that need to be locked, thereby improving the versatility of the locking assembly 100.

[0072] Please also read Figure 2 , Figure 3 and Figure 4 In some embodiments, the fixing portion 31 includes a bottom plate 312, a first side plate 313 and two second side plates 314, and the bottom plate 312 is configured to abut against the first locking member 20. The first side plate 313 and the two second side plates 314 are arranged around the bottom plate 312, and the two second side plates 314 are arranged opposite to each other. The receiving groove 311 is formed between the bottom plate 312, the first side plate 313 and the two second side plates 314, and the elastic portion 33 elastically abuts between the bottom plate 312 and the first clamping end 322. Through the above arrangement, the first clamping end 322 and the elastic portion 33 are both arranged in the receiving groove 311, thereby improving the space utilization rate of the second locking member 30.

Through the above arrangement, the rotating rod 34 is arranged in the receiving groove 311 and is located between the two second side plates 314. The connecting end 321 rotates around the rotating rod 34 under the action of an external force to realize the rotation of the clamping portion 32 relative to the fixing portion 31, thereby reducing the risk of the clamping portion 32 being separated from the fixing portion 31.

[0074] Please continue reading Figure 3 and Figure 4 In some embodiments, the clamping portion 32 also includes a pressing end 324, which is connected to the connecting end 321 and extends in a direction away from the fixing portion 31, so that the user can press the pressing end 324 with one hand, thereby driving the connecting end 321 and the first clamping end 322 and the second clamping end 323 connected to the connecting end 321 to rotate relative to the fixing portion 31 to achieve the closing or opening of the locking assembly 100.

[0075] Please also read Figure 1 and Figure 2 In some embodiments, the fixing portion 31 further includes a stopper 315, which is connected to the side of the bottom plate 312 away from the elastic portion 33.

The clamping portion 32 includes a connecting end 321, and a first clamping end 322 and a second clamping end 323 extending from different directions of the connecting end 321, respectively. The connecting end 321 and the fixing portion 31 are rotatably connected, the first clamping end 322 is provided in the receiving groove 311, and the elastic portion 33 is elastically abutted between the fixing portion 31 and the first clamping end 322. A clamping groove 3231 is provided at one end of the second clamping end 323 away from the first clamping end 322. The first clamping end 322 is configured to push the clamping groove 3231 on the second clamping end 323 to clamp the protrusion 21 under the elastic force of the elastic portion 33.

[0079] The cover mechanism 40 includes a cover 41, which is rotatably connected to the base 10 to achieve a transition between a first position 411 and a second position 412. The end of the cover 41 is connected to the fixing portion 31, and the cover 41 is configured to drive the fixing portion 31 to abut against the first locking member 20 when rotating from the first position 411 to the second position 412.

[0080] In this embodiment, the cover plate 41 is in an open state when it is in the first position 411 , and is in a closed state when it is in the second position 412 .

[0081] In the above-mentioned locking device 200, when the user drives the cover plate 41 to rotate from the first position 411 to the second position 412 with one hand, the fixing portion 31 connected to the cover plate 41 is placed on the first locking member 20. At this time, the user can drive the second clamping end 323 to rotate relative to the fixing portion 31 with one hand, so that the clamping groove 3231 on the second clamping end 323 clamps the protrusion 21 on the first locking member 20. When the user drives the cover plate 41 to rotate from the second position 412 to the first position 411 with one hand, the user can drive the first clamping end 322 to rotate relative to the fixing portion 31 with one hand and apply pressure to the elastic portion 33. At this time, the second clamping end 323 rotates with the first clamping end 322 and separates from the fixing portion 31, so that the protrusion 21 can be separated from the clamping groove 3231 on the second clamping end 323, so that the user can drive the cover plate 41 to close or open with one hand, thereby improving the convenience of using the locking device 200.

[0082] Please also read Figure 4 , Figure 5 and Figure 6In some embodiments, a first inclined wedge surface 3232 is provided at one end of the second holding end 323 away from the connection end 321, and the first inclined wedge surface 3232 is disposed adjacent to the holding groove 3231.
