Abstract
Description
Technical Field
[0001] This utility model relates to the field of storage cabinet technology, and in particular to an impact-resistant sheet metal mirror cabinet for a high-speed train washroom. Background Technology
[0002] With the development of high-speed rail, the internal facilities of bullet trains are constantly being upgraded. As a space that passengers use frequently, the functionality and safety design of the washroom are particularly important. The sheet metal mirror cabinet, as an important component inside the washroom for temporary storage of items and mirror cleaning, not only needs to meet the requirements of ease of use, but also needs to have good impact resistance and structural stability to cope with complex conditions such as vibration, impact or emergency braking that may occur during train operation.
[0003] Existing mirror cabinets in high-speed train washrooms generally have simple structures, and most lack effective locking devices, making it impossible to achieve closed control of the cabinets and lacking the ability to manage and control safety in response to emergencies. In addition, the simple internal structure of traditional mirror cabinets makes it easy for items to slip or shift, especially at high speeds, where the lack of effective restraint structures poses a safety hazard.
[0004] Therefore, we propose an impact-resistant sheet metal mirror cabinet for high-speed train washrooms to solve the existing problems. Utility Model Content
[0005] The purpose of this utility model is to address the problems existing in the background technology by proposing an impact-resistant sheet metal mirror cabinet for the washroom of a high-speed train.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an impact-resistant sheet metal mirror cabinet for a high-speed train washroom, comprising a cabinet body, a secondary door, and a main door, characterized in that: the front opening of the cabinet body is respectively provided with a secondary door and a main door via two multi-link hinges, the secondary door is provided with an extension block, and the main door presses on the extension block;
[0007] The cabinet has an internal shelf panel, and a baffle is movably installed at the front end of the shelf panel;
[0008] A locking component is provided between the cabinet and the main door, which is used to lock the cabinet and the main door together.
[0009] Preferably, the multi-link hinge consists of a first pin seat, an arc-shaped rod, a beam rod, and a second pin seat. The first pin seat is fixedly mounted on the inner wall of the cabinet. One end of the arc-shaped rod is rotatably mounted on the first pin seat. One end of the beam rod is rotatably mounted on the other end of the arc-shaped rod. The second pin seat is rotatably mounted on the other end of the beam rod. The second pin seat is fixedly connected to the corresponding door.
[0010] Preferably, the locking assembly consists of a hanging block, a hook, a main body shell, an operating head, and a shaft. The main body shell is fixedly installed at the bottom of the inner wall of the cabinet, the shaft is rotatably installed on the main body shell, the hook is fixedly installed at the top of the shaft, and the operating head is fixedly installed at the bottom of the shaft.
[0011] Preferably, the hanging block is fixedly mounted on the main door, and the hook relies on rotation to complete the engagement and disengagement actions with the hanging block.
[0012] Preferably, sockets are symmetrically fixedly arranged on the interlayer plate, and the interlayer plate is slidably inserted between two sockets.
[0013] Preferably, the back of the cabinet is provided with mounting screw holes at equal intervals.
[0014] Preferably, the bottom of the secondary door and the main door are designed with a slope, and the slope protrudes from the lower surface of the cabinet.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] This utility model is an impact-resistant sheet metal mirror cabinet for high-speed train washrooms. During use, the mirror cabinet can be fixed to a designated position in the high-speed train washroom through the mounting screw holes on the back. A mirror can be installed inside the cabinet for personnel to groom their appearance.
[0017] When needed, the main door and the secondary door can be opened to temporarily store items on the shelf inside the cabinet. At this time, the design of the baffle can prevent items from moving out of the shelf, which can prevent items from being damaged due to vibration during train operation.
[0018] Furthermore, in specific situations, when train personnel do not wish for personnel to use the mirror cabinet, the train personnel insert a special key into the operating head, and then control the operating head to rotate using the key. The operating head drives the shaft to rotate, and the shaft drives the hook to rotate, thereby making the hook and the hanging block interlock. At this time, the main door cannot be opened, and through the design of the extension block, the main door presses against the extension block, making the secondary door unable to be opened either, thus completing the locking of the cabinet.
[0019] This utility model has an extension block between the main door and the secondary door. When the main door is closed, it covers the extension block of the secondary door to achieve indirect locking of the secondary door. At the same time, in conjunction with the locking components composed of hanging blocks, hooks, and operating heads, the cabinet door can be completely closed. It is suitable for locking management during train operation or non-passenger use periods to ensure equipment safety.
[0020] The cabinet has movable baffles at the front of the internal shelf panels, which can effectively prevent items from slipping or tipping over when the train accelerates or vibrates, thus improving the stability of the stored items and preventing damage to items or mess in the washroom due to falls.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] Example 1
[0030] like Figures 1-5 As shown, the present invention proposes an impact-resistant sheet metal mirror cabinet for a high-speed train washroom, comprising a cabinet body 1, a secondary door 2 and a main door 3. The front opening of the cabinet body 1 is rotatably connected to the secondary door 2 and the main door 3 by two multi-link hinges 4. An extension block 201 is provided on the secondary door 2. When the main door 3 is closed, it presses against the extension block 201, thereby indirectly limiting the movement of the secondary door 2.
[0031] This linkage limit structure can automatically restrict the opening of the secondary door 2 when the main door 3 is closed without the need for additional complex linkage mechanisms or elastic components, thus improving the simplicity and reliability of the structure.
[0032] The multi-link hinge 4 includes a first pin seat 401, an arc-shaped rod 402, a beam rod 403, and a second pin seat 404. The first pin seat 401 is fixed to the inner wall of the cabinet 1. One end of the arc-shaped rod 402 is rotatably connected to the first pin seat 401. One end of the beam rod 403 is rotatably connected to the other end of the arc-shaped rod 402. The second pin seat 404 is installed on the other end of the beam rod 403 and fixed to the corresponding door. Through the above structure, the multi-link hinge 4 can realize the buffered movement trajectory during the opening and closing of the door, improving the overall stability of use. This structure can provide segmented buffer support during the opening of the door, preventing the door from rebounding quickly under the action of external force.
[0033] Several mounting screw holes are evenly spaced on the back of cabinet 1 to install the entire mirror cabinet structure in a designated position in the washing room of the high-speed train, which facilitates disassembly and maintenance. The bottom ends of the main door 3 and the secondary door 2 are sloping, with the sloping surface protruding from the lower surface of cabinet 1 to optimize the human-machine operation angle.
[0034] The cabinet 1 has an internal shelf 5. A baffle 6 is movably installed at the front end of the shelf 5 to prevent items temporarily placed on the shelf 5 from slipping off during train operation. The two sides of the shelf 5 are symmetrically inserted between sockets 7. The sockets 7 are fixed to the inner wall of the cabinet 1. The shelf 5 can be disassembled and assembled by sliding.
[0035] Example 2
[0036] like Figures 1-5 As shown, the present invention proposes an impact-resistant sheet metal mirror cabinet for the washroom of a high-speed train. Compared with the first embodiment, this embodiment further includes a locking component 8 between the cabinet body 1 and the main door 3, which is used to realize the opening and closing locking control of the main door 3. This structure can be forcibly locked when the crew needs to restrict passengers from using the mirror cabinet, which helps to improve the standardization of train management and safety control capabilities. It is particularly suitable for special scenarios such as nighttime rest periods, fault maintenance periods, or closed management.
[0037] The locking assembly 8 includes a hanging block 801, a hook 802, a main body shell 803, an operating head 804, and a shaft 805. The hanging block 801 is fixedly installed on the main door 3, the main body shell 803 is fixed to the bottom of the inner wall of the cabinet 1, the shaft 805 is rotatably installed on the main body shell 803, the hook 802 is fixed to the top of the shaft 805, and the operating head 804 is fixed to the bottom of the shaft 805. During use, a specific key can be inserted into the operating head 804 and rotated to drive the shaft 805 to rotate the hook 802, so that the hook 802 and the hanging block 801 can be engaged and released, thereby controlling the opening and locking of the main door 3. This structure can achieve quick locking and unlocking through a simple rotation action, without the need for an external power supply or complex control module. The structure is reliable and the response is fast, avoiding the problems of misoperation or power failure that may be encountered when using electronic locks in high-speed rail washrooms.
[0038] After the main door 3 is locked, it presses down the extension block 201, thereby indirectly locking the secondary door 2, achieving simultaneous closing of both doors. The operation is convenient and the sealing effect is stable. The overall locking component 8 is placed below the cabinet 1, in a concealed position, which improves security and reduces the chance of accidental activation.
[0039] The above specific embodiments are merely several preferred embodiments of this utility model.
