Description

Technical Field

[0001] The present disclosure generally relates to the technical field of locks, and particularly to a double-lock structure and a cabinet structure equipped with the double-lock structure. Background Art

[0002] In the prior art, the door lock of a self-service terminal device is generally a cylindrical lock, which uses a single lock tongue to hook the door frame to achieve the closing between the cabinet door and the frame. However, this single-lock method cannot meet the requirement of dual management. One person can complete the unlocking and locking, resulting in a low level of security. On the other hand, the locking depends on turning the key to the locking position. Once forgetting to use the key to lock, the lock will be in the unlocked state, which may lead to forgetting to close the cabinet door and affect the security of the device.

[0003] Therefore, the prior art needs to be improved. Summary of the Utility Model

[0004] In view of the above-mentioned defects or deficiencies in the prior art, it is desired to provide a double-lock structure and a cabinet that can meet the actual usage requirements.

[0005] Based on one aspect of the embodiments of the present application, the embodiments of the present application provide a double-lock structure, which includes:

[0006] A housing, a first lock structure, a second lock structure, and a cover plate;

[0007] The first lock structure and the second lock structure are arranged side by side inside the housing, and the cover plate is used to fix the opening of the housing to form a cavity space in the housing;

[0008] The first lock structure includes: a first lock core, a first linkage slide, a first lock rod, a first connecting piece, and a first spring;

[0009] A keyhole is provided in the middle of the first lock core. When the key rotates in the keyhole, the first lock core rotates accordingly;

[0010] One end of the first lock core is connected to the first linkage slide. When the first lock core rotates driven by the key, it drives the first linkage slide to move towards the first lock core;

[0011] The first connecting piece is in an "L" shape. One end of it is connected to the first linkage slide, and the other end is connected to the first lock rod. When the first linkage slide moves towards the first lock core, it drives the first connecting piece to move synchronously, thereby driving the first lock rod to move towards the first lock core;

[0012] One end of the first spring is connected to the housing, and the other end is connected to the first connecting member at the connection with the first linkage sliding piece. When the first connecting member moves towards the first lock core under the drive of the first linkage sliding piece, the first spring is stretched by the pulling force of the first connecting member. When the force of the first linkage sliding piece on the first connecting member disappears, the first spring restores the first connecting member to its initial position, so that the first lock core, the first linkage sliding piece, and the first lock rod all return to their initial positions;

[0013] The second lock structure is the same as the first lock structure.

[0014] In another embodiment, the first lock rod is of a straight rod structure and extends out of the housing through the upper opening of the housing. When the first lock core drives the first linkage sliding piece towards the first lock core under the acting force of the key rotation, the first connecting member is driven to move with the first linkage sliding piece, thereby driving the first lock rod to move towards the first lock core. When the acting force of the key rotation on the first lock core disappears, the first spring restores the first connecting member to its initial position, so that the first lock rod returns to its initial position.

[0015] Based on another aspect of the embodiments of the present application, a cabinet is disclosed. The double-lock structure described in the embodiments of the present application is provided on the cabinet, and the cabinet includes a cabinet door and a frame;

[0016] The double-lock structure is provided on the cabinet door;

[0017] When the first lock structure and the second lock structure simultaneously insert keys and apply a force to rotate the keys to a set position, the first lock structure and the second lock structure will unlock, and the cabinet door and the frame are in an unlocked and separated state;

[0018] When the acting force applied by the key inserted into the first lock structure or the second lock structure disappears, the first lock structure or the second lock structure will return to its initial state, the cabinet door is fixed on the frame, and the cabinet door and the frame are in a locked and combined state.

[0019] In the embodiments of the present application, by providing the first lock structure and the second lock structure with the same structure in the housing, the first lock structure includes a first lock core, a first linkage sliding piece, a first lock rod, a first connecting member, and a first spring; the first lock core drives the first connecting member to move through the first linkage sliding piece, thereby driving the first lock rod to move, and the first spring controls the reset of the first connecting member. The present application can effectively solve the problem of the insecurity of a single lock body, manage with double-person and double-lock, and when the key is pulled out, the lock body is naturally locked, and the situation of forgetting to lock will not occur, greatly improving the safety level.

[0020] Other features, objects, and advantages of the present application will become more apparent by reading the detailed description of non-limiting embodiments with reference to the following drawings:

[0021] Figure 1 An exemplary schematic diagram of a double-lock structure according to an embodiment of the present application is shown.

[0022] In the formula, 100 is the housing, 200 is the first lock structure, 300 is the second lock structure, and 400 is the cover plate;

[0023] 201 is the first lock core, 202 is the first linkage sliding piece, 203 is the first lock rod, 204 is the first connecting piece, and 205 is the first spring. Detailed implementation manners

[0024] The present application will be further described in detail below with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the related technical solutions and do not limit the present application. Additionally, it should be noted that for the convenience of description, only parts related to the present application are shown in the drawings.

[0025] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application will be described in detail below with reference to the drawings and embodiments.

[0026] As Figure 1 shown, the double-lock structure of this embodiment includes:

[0027] A housing 100, a first lock structure 200, a second lock structure 300, and a cover plate 400;

[0028] The first lock structure 200 and the second lock structure 300 are arranged in parallel inside the housing 100, and the cover plate 400 is used to fix the opening of the housing 100 to form a cavity space in the housing 100;

[0029] The first lock structure 200 includes: a first lock core 201, a first linkage sliding piece 202, a first lock rod 203, a first connecting piece 204, and a first spring 205;

[0030] A keyhole is provided in the middle of the first lock core 201. When the key rotates in the keyhole, the first lock core 201 rotates accordingly;

[0031] One end of the first lock core 201 is connected to the first linkage sliding piece 202. When the first lock core 201 rotates driven by the key, it drives the first linkage sliding piece 202 to move towards the direction of the first lock core 201;

[0032] The first connecting member 204 is an L-shaped structure, one end of which is connected to the first linkage slide 202, and the other end is connected to the first locking rod 203. When the first linkage slide 202 moves toward the first lock cylinder 201, the first connecting member 204 is driven to move synchronously, thereby driving the first locking rod 203 to move toward the first lock cylinder 201;

[0033] One end of the first spring 205 is connected to the housing 100, and the other end is connected to the first connecting member 204 at the connection with the first linkage slide 202. When the first connecting member 204 moves toward the first lock cylinder 201 under the drive of the first linkage slide 202, the first spring 205 is pulled by the first connecting member 204 and its side lengthens. When the force of the first linkage slide 202 on the first connecting member 204 disappears, the first spring 205 restores the first connecting member 204 to its initial position, thereby restoring the first lock cylinder 201, the first linkage slide 202, and the first lock rod 203 to their initial positions.

[0034] Specifically, since the first linkage slide 202 and the first spring 205 are respectively located on both sides of the first connecting member 204, when the key is inserted into the first lock cylinder 201 and rotated, the first linkage slide 202 will move toward the first lock cylinder 201, which will inevitably drive the first spring 205 to be stretched, thereby generating a pulling force in the opposite direction of the first lock cylinder 201. At this time, if the key in the first lock cylinder 201 is pulled out, or the force applied by the key disappears, the first spring 205 will pull the first connecting member 204 to move in the opposite direction of the first lock cylinder 201, thereby driving the first linkage slide 202 to move synchronously in the opposite direction of the first lock cylinder 201, thereby restoring the lock hole of the first lock cylinder 201 to its original state. Since the first locking rod 203 is fixed on the same side of the first connecting member 204 as the first spring 205, when the first spring 205 contracts without external force, the first locking rod 203 will also move in the opposite direction of the first lock core 201 as the first connecting member 204 moves, so that the first locking rod 203 is equivalent to being away from the first lock core 201. According to the unlocking and locking principles of the door lock, when the first locking rod 203 is away from the first lock core 201, it is equivalent to inserting the first locking rod 203 into the locking hole, thereby realizing the locking of the door lock. When the first locking rod 203 moves toward the first lock core 201, it is equivalent to moving the first locking rod 203 away from the locking hole, thereby realizing the unlocking of the door lock.

[0035] The second lock structure 300 is the same as the first lock structure 200. Since this application is a double-body lock, the first lock structure 200 and the second lock structure 300 are respectively responsible for locking and unlocking the upper and lower ends of a door. In this way, the double-lock structure realizes the unlocking and locking of the upper and lower ends of a door.

[0036] In another embodiment, the first lock rod 203 is in a straight rod shape and extends out of the upper opening of the housing 100. When the first lock core 201 drives the first linkage slide 202 to move in the direction of the first lock core 201 under the driving force of the key rotation, it drives the first connecting member 204 to move with the first linkage slide 202, thereby driving the first lock rod 203 to move in the direction of the first lock core 201. When the driving force of the key rotation disappears from the first lock core 201, the first spring 205 restores the first connecting member 204 to its initial position, thereby causing the first lock rod 203 to return to its initial position.

[0037] Based on the disclosure of an embodiment of this application, a cabinet body is provided with the double-lock structure described in the embodiment of this application. The cabinet body includes a cabinet door and a frame;

[0038] The double-lock structure is provided on the cabinet door;

[0039] When the first lock structure 200 and the second lock structure 300 simultaneously insert the key and apply a force to rotate the key to the set position, the first lock structure 200 and the second lock structure 300 will unlock, and the cabinet door and the frame are in an unlocked and separated state;

[0040] When the force applied to the key inserted into the first lock structure 200 or the second lock structure 300 disappears, the first lock structure 200 or the second lock structure 300 will return to its initial state, the cabinet door is fixed on the frame, and the cabinet door and the frame are in a locked and combined state.

[0041] Specifically, a double-lock structure is provided on the cabinet door. The first lock structure 200 is responsible for locking the upper end of the cabinet door to the frame, and the second lock structure 300 is responsible for locking the lower end of the cabinet door to the frame. The structures and working principles of the first lock structure 200 and the second lock structure 300 are exactly the same.

[0042] In the initial state, both the first lock structure 200 and the second lock structure 300 are in a locked state, and the lock rods of the first lock structure 200 and the second lock structure 300 are inserted into the lock rod holes of the frame to realize the locking of the cabinet door and the frame.

[0043] When the key of the first lock structure 200 is inserted into the keyhole of the first lock core 201 and rotated in the set direction, the key generates an upward pulling force on the first linkage sliding piece 202 through the keyhole. At this time, since the first linkage sliding piece 202 is connected to the first connecting piece 204, when the first linkage sliding piece 202 moves towards the first lock core 201, the first connecting piece 204 will also move towards the first lock core 201. Since one end of the first spring 205 is fixed on the housing 100 and the other end is fixed on the first connecting piece 204, when the first connecting piece 204 also moves towards the first lock core 201, the first spring 205 will be stretched to generate a pulling force in the opposite direction. At the same time, since the first lock rod 203 is also fixed on the first connecting piece 204, at this time, the movement of the first connecting piece 204 will also drive the first lock rod 203 to move synchronously. When the key rotates to the set position, the first lock rod 203 will be pulled out from the lock rod hole of the frame. At this time, the first lock structure 200 on the cabinet door will be separated from the frame, and the unlocking of the first lock structure 200 is realized at this time. When the unlocking is completed, if the key is released at this time and the first lock rod 203 is not aligned with the lock rod hole of the frame, the first lock rod 203 will return to its original position, but the door closing is not realized. Only when the first lock rod 203 is aligned with the lock rod hole of the frame and the key is released at the same time, the first lock rod 203 can be inserted into the lock rod hole of the frame to realize the door closing.

[0044] The unlocking and locking methods of the second lock structure 300 are exactly the same as those of the first lock structure 200.

[0045] The above description is only the preferred embodiment of the present application and the explanation of the applied technical principles. Those skilled in the art should understand that the scope of the utility model involved in the present application is not limited to the technical solutions formed by the specific combination of the above technical features, and should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the inventive concept of the utility model. For example, the technical solutions formed by mutually replacing the above features with the (but not limited to) technical features with similar functions disclosed in the present application.
