Description

Technical Field

[0001] This utility model relates to the field of cabinet technology, and in particular to a cabinet with a safety lock. Background Technology

[0002] Cabinet units with security locking features have wide applications in industrial, commercial, and residential settings. Their core function is to prevent unauthorized access through physical or electronic means, thereby ensuring the security of equipment, data, or stored items.

[0003] Currently, cabinet air conditioners typically use mechanical or electronic locks on the doors to lock the doors and prevent unauthorized personnel from accessing or removing internal items. However, existing mechanical lock structures mainly rely on the lock cylinder and the opposite hinge to connect to the cabinet body, while the edges of the door panel are only in a mating state, resulting in poor overall door locking stability. This is especially true in double-door structures, where the connection stability at the lock cylinder is insufficient after locking, affecting overall security.

[0004] Therefore, there is an urgent need for a cabinet machine with a security lock that offers higher security and stability. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, the present invention provides a cabinet with a security lock that has higher security and stability.

[0006] The technical implementation scheme of this utility model is as follows: a cabinet-type air conditioner with a safety lock includes a bracket, a base plate, a frame, a top plate, opening and closing doors, a mechanical lock, a protective cover, a mounting plate, an eccentric rotating shaft, a motor, a movable plate, and a locking plate. The base plate is mounted on the bracket, the frame is mounted on the base plate, and the top plate is mounted on the top of the frame. Opening and closing doors are hinged to the left and right sides and the front sides of the frame. Mechanical locks are installed between the opening and closing doors on the front sides and between the opening and closing doors on the left and right sides and the frame. Protective covers are installed on both the top and bottom plates, and each of the top and bottom plates has a set of spaced-out features. Mounting plates are located inside the corresponding protective covers. One of the mounting plates in each of the two sets is equipped with a motor. An eccentric shaft is rotatably connected between the two mounting plates in the same set. The shaft end of the eccentric shaft is connected to the output end of the motor on the same side. A movable plate is fitted on the eccentric shaft. There is space between the movable plate and the corresponding eccentric shaft for contact sliding. The movable plates on both sides also form a sliding fit with the corresponding top plate or bottom plate. The movable plates are equipped with a locking plate corresponding to the number and position of each opening and closing door. The locking plate slides through the corresponding top plate or bottom plate and engages with the adjacent opening and closing door.

[0007] As an improvement to the above solution, it also includes a guide block 1, a pressing rod, a guide block 2, a limiting rod, and an elastic element. Each opening and closing door has crisscrossing grooves. Each groove has a guide block 1 that matches the layout, quantity, and position of the card plates. Each guide block 1 has a pressing rod that slides on it and contacts and cooperates with each adjacent card plate. Each groove has a guide block 2 located next to the pressing rod. Each guide block 2 has a limiting rod that slides on it and contacts and abuts against the adjacent pressing rod. An elastic element is provided between the limiting rod and the corresponding guide block 2. The limiting rod is inserted and cooperates with the opposite opening and closing door and the frame.

[0008] As an improvement to the above solution, the end of the extrusion rod that contacts the corresponding limiting rod has a wedge-shaped surface that is compatible.

[0009] As an improvement to the above solution, lighting is also included, with one lighting lamp installed on each side of the upper protective cover.

[0010] As an improvement to the above solution, a camera is also included, with a camera installed on the front of the upper protective cover.

[0011] As an improvement to the above solution, the bottom of the bracket is raised around its perimeter.

[0012] The present invention has the following advantages: 1. The present invention sets up an eccentric rotating shaft driven by a motor to drive the movable plate and the locking plate to move in coordination, so as to realize the precise insertion and locking of the upper and lower ends of the door. This not only significantly improves the overall locking strength of the cabinet, but also effectively overcomes the problem of structural loosening and insufficient anti-pry performance caused by traditional mechanical locks relying only on single-point locking, thereby greatly improving the safety and stability of the cabinet.

[0013] 2. Based on the card plate locking structure, this utility model further introduces a linkage mechanism between the compression rod and the limit rod, and cooperates with the elastic element to realize automatic insertion-type lateral locking, so that both sides of the door can complete the locking action simultaneously during the closing process, forming a three-dimensional locking structure with all-round and multi-point linkage in all directions, thereby comprehensively enhancing the anti-pry capability of the cabinet door and the stability of the overall structure.

Detailed Implementation

[0019] The above-described solution will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of this application. The implementation conditions used in the embodiments may be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are generally those in routine experiments.

[0020] Example: A cabinet machine with a security lock, such as Figures 1-3 As shown, the system includes a bracket 1, a base plate 2, a frame 3, a top plate 4, hinged doors 5, a mechanical lock 6, a protective cover 7, a mounting plate 8, an eccentric rotating shaft 9, a motor 10, a movable plate 11, and a locking plate 12. The bracket 1 is the basic support component of the overall structure. Its bottom is raised around the perimeter, which not only enhances the stability of the cabinet when placed on the ground, but also effectively prevents external liquids from seeping into the interior, improving the safety and service life of the equipment. The base plate 2 is mounted on the bracket 1, the frame 3 is mounted on the base plate 2, and the top plate 4 is mounted on the top of the frame 3, thus constructing a complete cabinet frame structure. Hinged doors 5 are hinged on the left, right, and front sides of the frame 3, forming a multi-sided openable structure, facilitating operation and maintenance from different directions. Mechanical locks 6 are installed between the hinged doors 5 on the front sides and between the hinged doors 5 on the left and right sides and the frame 3 to achieve basic closure and locking functions, ensuring that the doors are not easily opened when not in use. The top plate 4 and... Each base plate 2 is equipped with a protective cover 7, and each top plate 4 and base plate 2 is equipped with a set of spaced mounting plates 8. The mounting plates 8 are located inside the corresponding protective covers 7 to protect the internal locking structure from external environmental influences and improve the overall appearance. One of the mounting plates 8 in each set is equipped with a motor 10. An eccentric shaft 9 is rotatably connected between the two mounting plates 8 in the same set. The shaft end of the eccentric shaft 9 is connected to the output end of the motor 10 on the same side. A movable plate 11 is sleeved on each eccentric shaft 9. There is a space between the movable plate 11 and the corresponding eccentric shaft 9 for contact sliding, so that when the eccentric shaft 9 rotates, it can drive the movable plate 11 to produce linear displacement movement. The movable plates 11 on both sides also form a sliding fit with the corresponding top plate 4 or base plate 2. The movable plate 11 is equipped with a locking plate 12 corresponding to the number and position of each opening and closing door 5. The locking plate 12 slides through the corresponding top plate 4 or base plate 2 and engages with the adjacent opening and closing door 5.

[0021] Specifically, the eccentric shaft 9 is driven to rotate by the motor 10, which in turn moves the movable plate 11 along the guide direction to achieve automated locking and unlocking operations. The locking plate 12 moves with the movable plate 11 and inserts into the end of the opening and closing door, forming a rigid limit in the vertical direction, which effectively prevents the opening and closing door 5 from loosening or opening due to external force, and enhances the stability and safety of the overall structure. It can be seen that the cabinet achieves efficient and stable locking of multiple opening and closing doors 5 through a reasonably arranged mechanical transmission structure and locking components. It has the advantages of compact structure, reliable operation and simple operation, and is suitable for various high-safety scenarios.

[0022] like Figure 4 As shown, it also includes guide block 13, pressing rod 14, guide block 2 15, limiting rod 16, and elastic element 17. Each opening and closing door 5 has crisscrossing grooves. Each groove contains guide block 13 that matches the layout and number of the card plates 12. Each guide block 13 has a pressing rod 14 slidably mounted on it, contacting and engaging with adjacent card plates 12. Each groove also contains guide block 2 15 located beside the adjacent pressing rod 14. Each guide block 2 15 has a limiting rod 16 slidably mounted on it, contacting and abutting with the adjacent pressing rod 14. The pressing rod 14 and... The end of the corresponding limiting rod 16 that contacts the limiting rod 16 has a wedge-shaped surface that is adapted to it. An elastic element 17 is provided between the limiting rod 16 and the corresponding guide block 15. In this embodiment, the elastic element 17 is a spring. The limiting rod 16 is inserted and cooperated with the corresponding opening and closing door 5 and the frame 3, so that when there is no external force, the limiting rod 16 automatically resets with the elastic force of the elastic element 17, and can be inserted into the corresponding opening and closing door 5 and the frame 3 when needed. On the basis of the card plate 12, a side locking point is added to form a locking structure in all directions, which greatly enhances the anti-pry and stability of the cabinet.

[0023] like Figure 1 As shown, it also includes a lighting lamp 18. A lighting lamp 18 is provided on each side of the upper protective cover 7, which can provide local lighting, making it easier to operate or maintain the equipment in low light conditions and improving the user experience.

[0024] like Figure 1 As shown, it also includes a camera 19. The front of the upper protective cover 7 is equipped with a camera 19, which is used to monitor the environmental conditions around the cabinet in real time and enhance security capabilities.

[0025] During use, if it is necessary to lock each of the opening and closing doors 5, first close each door 5 to lock the mechanical lock 6. Then start the motor 10 to drive the eccentric shaft 9 connected to it to rotate between the corresponding mounting plates 8. As the eccentric shaft 9 rotates, it drives the movable plate 11 on it to move synchronously and slide on the bottom plate 2 or top plate 4. The movement of the movable plate 11 causes the locking plate 12 connected to it to move accordingly and insert into the corresponding top plate 4 or bottom plate 2, thereby locking into the end of the opening and closing door 5, fixing the vertical position of the opening and closing door 5, thus enhancing the stability of the overall structure.

[0026] Meanwhile, during insertion, the locking plate 12 contacts the corresponding pressing rod 14. As the locking plate 12 penetrates further, it pushes the pressing rod 14 to slide along the guide block 13 and contact the limiting rod 16. The contact surface of the two is a wedge-shaped structure, which, after mating, pushes the limiting rod 16 to slide along the guide block 15, causing the elastic element 17 to deform. Finally, the limiting rod 16 is inserted into the corresponding opening and closing door 5 or frame 3 structure, further stabilizing the position of both sides of the opening and closing door 5, thereby achieving comprehensive safety locking.

[0027] When the door 5 needs to be opened, the motor 10 is started and its output end is reversed, causing the movable plate 11 to slide in the opposite direction, thereby releasing the locking plate 12 from the locked state of the door 5 and releasing the pushing action on the pressing rod 14. At this time, the limiting rod 16 loses its pressing action and resets under the action of the elastic element 17, thereby releasing the locking restriction on the door 5 and facilitating the opening operation of the door 5.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that variations may be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
