[0026] like Figure 1The multi-functional tool cabinet with a foldable chair shown includes: a tool cabinet 1 body, and a backrest assembly 2 hinged to one side of the upper surface of the tool cabinet 1 to form a chair back on the surface of the tool cabinet 1 when opened. The backrest assembly 2 includes: a connecting plate 21 hinged to one side of the upper surface of the tool cabinet 1, and a support plate 22 hinged to the other end of the connecting plate 21.

[0027] The front end of the upper surface of the tool cabinet 1 is provided with a U-shaped groove 3, and a seat plate 4 is provided in the U-shaped groove 3;

[0028] Hydraulic support rod I5 is provided between the connecting plate 21 and the interior of the tool cabinet 1. On both sides of the upper surface of the tool cabinet 1, near the U-shaped groove 3, a pair of limiting mechanisms are provided to cooperate with the inner side of the support plate 22.

[0029] Working principle:

[0030] This tool cabinet 1 is installed on the train's maintenance car. During use, the connecting plate 21 (hinged to the upper surface of the tool cabinet 1) is manually lifted, and the hydraulic support rod I5 extends synchronously to provide support, pushing the connecting plate 21 to a preset angle. The support plate 22 rotates inward through the hinge point with the connecting plate 21 until its inner side engages with the limiting mechanisms on both sides of the upper surface of the tool cabinet 1, forming a stable backrest support surface. The seat plate 4 in the U-shaped groove 3 has its front end flush with the front end of the tool cabinet 1. The seat plate 4, together with the backrest assembly 2 when opened, forms a complete seat structure. After completing their work, the worker can sit on the seat plate 4 and lean against the support plate 22. At the same time, the support plate 22 will not move backward under the action of the limiting mechanism. Furthermore, even when no worker is sitting, the hydraulic support rod I5 provides a certain supporting force to the connected plate 21 when opened, and the support plate 22 will not move forward. Manually push the support plate 22 towards the connecting plate 21 until the support plate 22 is flush with the connecting plate 21. At the same time, the hydraulic support rod I5 gradually retracts, and the connecting plate 21 slowly falls back to a state of contact with the upper surface of the tool cabinet 1. This makes the support plate 22 and the connecting plate 21 completely flush with the surface of the tool cabinet 1. The tool cabinet 1 adopts a foldable design, and the main body of the tool cabinet 1 has the functions of storage and seating. When the backrest assembly 2 is unfolded, it forms a seat with a backrest. The seat plate 4 in the U-shaped groove 3 provides a support surface, meets the needs of personnel to rest, and reduces space occupation.

[0031] In the above technical solution, the limiting mechanism includes a limiting hook 6 disposed on the tool cabinet 1; wherein, a limiting hole 7 is provided on the inner side of the support plate 22 at the position where it mates with the limiting hook 6, and an avoidance groove I8 is provided on the connecting plate 21 at the position where it mates with the limiting hook 6. With this technical solution, the limiting hook 6 is fixed to both sides of the upper surface of the tool cabinet 1 (near the U-shaped groove 3), adopting an L-shaped or barbed structure, and rigidly connected to the cabinet body of the tool cabinet 1 by bolts or welding. When the connecting plate 21 is raised and opened, the support plate 22 rotates around the connecting plate 21 to a certain angle with the top surface of the tool cabinet 1, the limiting hole 7 aligns with the limiting hook 6, and the hook head automatically engages in the hole to form a mechanical lock. Simultaneously, when the connecting plate 21 is closed, the connecting plate 21 rotates to be flush with the surface of the tool cabinet 1, and the limiting hook 6 extends into the avoidance groove I8. After closing, the connecting plate 21 and the top surface of the tool cabinet 1 form a continuous plane.

[0032] In the above technical solution, the upper surface of the support plate 22 is provided with multiple mounting slots 9, and each mounting slot 9 is hinged with an armrest 10, so that multiple seats are formed between the support plate 22 and the seat plate 4 when the support plate 22 is opened. With this technical solution, the armrests 10 are hinged in the mounting slots 9, and when not in use, the armrests 10 can be folded and stored in the mounting slots 9, making the surface of the support plate 22 flat and not affecting the storage space on the upper surface of the tool cabinet 1. The presence of the armrests 10 provides arm support for the user, increases comfort when sitting, reduces fatigue caused by prolonged sitting, and helps improve the user's experience and work efficiency.

[0033] In the above technical solution, the support plate 22 has multiple protrusions 11 spaced apart on the side near the connecting plate 21, each protrusion 11 having a headrest. A flexible backrest is provided on the upper surface of the support plate 22, a flexible seat cushion is provided on the upper surface of the seat plate 4, and a flexible layer is provided on the upper surface of the connecting plate 21. The connecting plate 21 has clearance grooves II 12 that mate with the protrusions 11, and the thickness of the flexible backrest is greater than the thickness of the armrest 10. Using this technical solution, the headrests on the multiple protrusions 11 provide support points for the occupant's head. During seating, especially during rest or relaxation, the headrests effectively relieve neck pressure and reduce fatigue caused by lack of head support. The flexible backrest, flexible seat cushion, and flexible layer on the connecting plate 21 increase the comfort of the parts in contact with the human body. The flexible material better conforms to the curves of the human body, distributing pressure on different parts of the seat and avoiding localized pressure caused by prolonged seating, thus making the seating experience more comfortable. The connecting plate 21 has a relief groove II 12 that matches the protrusion 11, so that when the backrest assembly 2 is folded and stored, the protrusion 11 can be embedded in it, ensuring that the connecting plate 21 and the surface of the tool cabinet 1 can be flat and fit together without taking up extra space. At the same time, the thickness of the flexible backrest is greater than the thickness of the armrest 10, so that when the backrest assembly 2 is stored, a single worker can lie on it to rest.

[0034] In the above technical solution, the seat plate 4 and the mounting groove 9 are hinged to each other to enclose the cavity inside the tool cabinet 1. With this technical solution, since the seat plate 4 and the mounting groove 9 are hinged, the seat plate 4 can be easily laid flat when the chair function is needed. However, when larger or longer tools need to be stored, the seat plate 4 can be rotated open to store the items.

[0035] In the above technical solution, the tool cabinet 1 has multiple drawers 13 at its bottom; wherein, the drawers 13 are located below the internal cavity of the tool cabinet 1. This technical solution provides ample storage space for categorized storage, allowing tools and items of different types and sizes to be stored separately in different drawers 13 for easy retrieval. For example, commonly used tools such as screwdrivers and wrenches can be placed in one drawer 13, while precision instruments or small parts can be placed in another, improving the efficiency and organization of tool management. The drawer-13 design makes item storage more orderly, avoiding the clutter of tools and items inside the tool cabinet 1, and allowing users to organize and categorize items according to their needs. Simultaneously, the drawer-13 design allows users to place large items inside the tool cabinet 1 and small items in the drawers 13.

[0036] In the above technical solution, a hydraulic support rod II 14 is provided between the seat plate 4 and the interior of the tool cabinet 1. Using this technical solution, the hydraulic support rod II 14 provides auxiliary support when the seat plate 4 is unfolded or retracted. When workers need to open the seat plate 4 to store items, the hydraulic support rod II 14 allows the operator to easily open the seat plate 4 and store the items. Simultaneously, the hydraulic support rod II 14 also prevents the seat plate 4 from falling when it is opened, providing support for the seat plate 4.

[0037] Although the embodiments of this utility model have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for this utility model. For those skilled in the art, other modifications can be easily made.
