[0030] The second unlocking mechanism 104 comprises a rotating block 1042 arranged on the lock cylinder 102 and a sliding block 1041 arranged in the lock shell 101, a pull rod 10421 is arranged on the rotating block 1042, and a slot 10411 for inserting the pull rod 10421 is arranged on the sliding block 1041, so that when the lock cylinder 102 rotates, the sliding block 1041 can move towards the first unlocking mechanism 103, and the sliding block 1041 is provided with a traction rope 2 connected with the first side lock 3, the traction rope 2 is a steel wire, when the sliding block 1041 moves in the lock shell 101 towards the first unlocking mechanism 103, the first side lock 3 is in an unlocked state; when the sliding block 1041 is not driven to slide in the lock shell 101, the first side lock 3 is in a locked state.

[0031] Referring to Figure 3 , Figure 4 , Figure 5 and Figure 6The first side lock 3 comprises a fixing seat 301, a locking driving member 302 and a locking executing member 303. The fixing seat 301 is arranged on the fixed frame 8, and the locking driving member 302 and the locking executing member 303 are arranged in the fixing seat 301 respectively. One end of the locking driving member 302 is connected with the traction rope 2. When the sliding block 1041 moves in the locking shell 101 towards the first unlocking mechanism 103, the locking driving member 302 slides in the fixing seat 301 relative to the locking executing member 303 under the traction of the traction rope 2. The locking executing member 303 comprises a rotating shaft 3032 and a hook 3031. The rotating shaft 3032 is arranged in the fixing seat 301, and the hook 3031 is hinged on the rotating shaft 3032. The hook 3031 comprises a fixedly connected abutting portion 30311 and an executing portion 30312. A first wedge surface 3021 capable of abutting with the abutting portion 30311 is arranged on the locking driving member 302. The executing portion 30312 is used for locking and unlocking between the back cover plate 7 and the fixed frame 8. When the locking driving member 302 is pulled by the traction rope 2 to slide in the fixing seat 301 relative to the abutting portion 30311, the abutting portion 30311 moves along the first wedge surface 3021. At this time, the abutting portion 30311 and the executing portion 30312 start to rotate around the axis of the rotating shaft 3032, which makes the executing portion 30312 no longer lock the back cover plate 7 on the fixed frame 8. Correspondingly, when the locking executing member 303 is not pulled by the traction rope 2, the abutting portion 30311 is in the original position. At this time, the executing portion 30312 locks the back cover plate 7 on the fixed frame 8.

[0032] Referring to Figure 7 and Figure 8 Further, a first spring 304 is arranged in the fixing seat 301 at the position corresponding to the executing portion 30312. One end of the first spring 304 is fixedly arranged in the fixing seat 301, and the other end of the first spring 304 abuts with the upper surface of the executing portion 30312. When the executing portion 30312 no longer locks between the fixed frame 8 and the back cover plate 7 under the sliding of the abutting portion 30311 along the first wedge surface 3021, the first spring 304 is in the compressed state. When the executing portion 30312 locks between the fixed frame 8 and the back cover plate 7, the first spring 304 is in the original length. This makes the executing portion 30312 re-lock between the fixed frame 8 and the back cover plate 7 under the elastic force of the first spring 304 when the back cover plate 7 is re-covered on the fixed frame 8 when the locking driving member 302 is not pulled by the traction rope 2. At this time, the abutting portion 30311 moves the locking driving member 302 to the position before being pulled by the traction rope 2 by abutting with the first wedge surface 3021.

[0033] Further, the pop-up mechanism 9 is further arranged on the back cover plate 7, the pop-up mechanism 9 comprises a plug rod 901, a third spring 902 and a limiting portion 903 arranged on the plug rod 901, wherein one end of the plug rod 901 is inserted on the back cover plate 7, the limiting portion 903 is coaxially fixed at the middle position of the length of the plug rod 901, the third spring 902 is sleeved on the end of the plug rod 901 inserted on the back cover plate 7, one end of the third spring 902 is fixedly connected with the back cover plate 7, and the other end of the third spring 902 is abutted with the limiting portion 903, when the back cover plate 7 covers on the fixed frame 8, the third spring 902 is in a compressed state, at this time, the execution part 30312 can lock the back cover plate 7 on the fixed frame 8; when the execution part 30312 unlocks between the back cover plate 7 and the fixed frame 8, the plug rod 901 is popped up under the action of the spring, so that the back cover plate 7 can be quickly popped up from the fixed frame 8, so that the user can more conveniently open the back cover plate 7 from the fixed frame 8 to realize the taking of the articles.

[0034] With reference to Figure 9 , Figure 10 and Figure 11 , the second side lock 4 in the embodiment 2 is further added on the basis of the embodiment 1, which can be connected in series with the locking execution part 303 or the sliding block 1041 through the traction rope 2, at least two traction ropes 2 can be arranged on the sliding block 1041, one of which is used for connecting the second side lock 4, and the other is connected with the locking driving part 302, it is worth mentioning that the number of the second side lock 4 can be one or more, and correspondingly, in addition to the traction rope 2 used for connecting the locking driving part 302, the number of the remaining traction ropes 2 corresponds to the number of the second side lock 4.

[0035] In addition to being directly connected with the traction rope 2 on the sliding block 1041, the second side lock 4 can also be directly connected with the locking driving part 302 through the traction rope 2, and the unlocking and locking of the second side lock 4 are realized by moving the locking driving part 302 through the sliding block 1041.

[0036] The second side lock 4 comprises a mounting seat 401, an unlocking block 402 and a locking block 403, wherein the mounting seat 401 is fixedly arranged on the longer frame of the fixed frame 8, the locking block 403 is slidingly arranged on the mounting seat 401 and can slide on the mounting seat 401 in the horizontal direction relative to the mounting seat 401, and the second spring 404 is further arranged in the mounting seat 401 for pushing one end of the locking block 403 out of the mounting seat 401, at this time, the locking block 403 is used to realize the locking between the back cover plate 7 and the fixed frame 8.

[0037] The upper locking block 403 is also arranged on the mounting base 401 and can slide in the vertical direction relative to the mounting base 401. The upper end of the unlocking block 402 is connected with the traction rope 2, and the lower end of the unlocking block 402 is arranged in the mounting base 401 and passes through the upper locking block 403. A second wedge surface 4021 is arranged at the position of the unlocking block 402 below the upper locking block 403 and abuts against the upper locking block 403. When the unlocking block 402 moves upward relative to the upper locking block 403 under the traction of the traction rope 2, the upper locking block 403 can slide along the direction of the second wedge surface 4021, so that the upper locking block 403 can retract on the mounting base 401. At this time, the second spring 404 is compressed, so as to realize the unlocking between the rear cover plate 7 and the fixed frame 8.

[0038] When it is needed to re-lock the rear cover plate 7 and the fixed frame 8, the lock core 102 can be rotated to the original position. At this time, the pushing block originally close to the first unlocking mechanism 103 moves away from the first unlocking mechanism 103 under the driving of the pushing rod 10421. This can make the traction rope 2 between the second sliding block and the locking driving part 302 or between the second sliding block and the pushing block have a margin for the second sliding block to move to the original position. At this time, the unlocking block 402 moves downward relative to the upper locking block 403 under the action of gravity. At this time, the traction rope 2 is in the straightened state again, and the upper locking block 403 is retracted from the mounting base 401 under the action of the elastic force of the second spring 404, so as to realize the locking between the rear cover plate 7 and the fixed frame 8.

[0039] The above are preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, any equivalent changes made on the basis of the structure, shape and principle of the present application should be covered within the protection scope of the present application.
