Description

Technical Field

[0001] This utility model relates to the technical field of trailer auxiliary tools, and more specifically, to a sliding toolbox for trailers. Background Technology

[0002] In the daily use and maintenance of trailers, the toolbox is an indispensable component. It is used to store various maintenance tools to ensure that the trailer can be repaired and maintained in a timely manner. However, traditional trailer toolboxes have many problems in design and use, making it difficult to meet actual needs.

[0003] For example, the toolbox door is inconvenient to open: Most traditional trailer toolboxes use side-opening or top-opening doors. Side-opening doors cannot be fully opened when the trailer is parked in a narrow space, making it extremely inconvenient to retrieve tools; although top-opening doors do not occupy side space when opened, they extend upwards after opening, making them prone to colliding with obstacles above the trailer. Moreover, when working at heights, opening the door will also affect the operator's line of sight and operating space, reducing work efficiency.

[0004] Furthermore, the access angle is limited: typical trailer toolboxes only have an opening on the front. When the trailer is poorly positioned, or there are other vehicles, equipment, or other obstacles nearby, it is difficult for operators to approach the toolbox from the front and retrieve the tools smoothly. This limitation of a single access angle severely restricts the practicality of the toolbox in complex working environments.

[0005] Secondly, the lack of door limiters: Many traditional trailer toolboxes lack effective door limiters. Once opened, the door can easily close accidentally due to vehicle vibration, wind, or accidental contact by the operator, potentially pinching the operator's hand and damaging the tools being retrieved. Furthermore, without limiters, the door may collide with the toolbox body during movement, generating noise and accelerating wear at the connection between the door and the body, thus reducing the toolbox's lifespan.

[0006] Furthermore, existing trailer toolboxes have relatively limited functionality, primarily focusing on tool storage while rarely considering convenience and safety during actual use. With the continuous development of the trailer transportation industry and increasingly stringent requirements for trailer maintenance efficiency and quality, these shortcomings of traditional toolboxes have become increasingly apparent, urgently necessitating a new type of trailer toolbox to address these issues and improve the efficiency and safety of trailer maintenance work. Utility Model Content

[0007] The purpose of this utility model is to overcome the shortcomings of the existing technology and to propose a sliding toolbox for trailers, comprising:

[0008] The box is used to store commonly used tools for trailer maintenance;

[0009] The box door can be fastened to the opening of the box.

[0010] The door opening and closing mechanism includes a hinge shaft one fixedly installed on the side of the box body, a rotating connecting rod hinged to the hinge shaft one, and the other end of the rotating connecting rod hinged to a hinge shaft two provided on the side of the door.

[0011] Preferably, the box body has openings on both the left and right sides for retrieving tools.

[0012] Preferably, the door opening and closing mechanism is further provided with a door limiting component, which includes a limiting slide rail formed on the side of the door and a limiting shaft fixedly installed on the bottom side of the box body, wherein the limiting slide rail and the limiting shaft are slidably connected.

[0013] Preferably, the end of the limiting slide is provided with an L-shaped limiting shaft groove.

[0014] Preferably, the enclosure is made of high-strength corrosion-resistant material to improve its service life and corrosion resistance.

[0015] Preferably, a sealing strip is provided between the door and the body of the box to prevent dust, rainwater, etc. from entering the box and to protect the internal tools.

[0016] Preferably, the surface of the rotating linkage is provided with an anti-slip coating, which facilitates the operator to manually operate the rotating linkage to open or close the box door.

[0017] Compared with existing technologies, the beneficial effects of this utility model are:

[0018] Ease of Use: The toolbox door opening mechanism employs a combination design of hinge shaft one, rotating link, and hinge shaft two. When the door is opened, it slides down along a specific trajectory via the rotating link. Compared to traditional side-opening or top-opening toolbox doors, this sliding opening method makes it easier for operators to access the toolbox in space-constrained trailer scenarios. There's no need to worry about the door occupying too much side or overhead space when open, allowing for easier and faster access to tools and significantly improving efficiency when performing maintenance work next to the trailer. When open, the door can be completely concealed at the bottom of the toolbox, making tool access even more convenient.

[0019] Multi-directional access flexibility: Openings for accessing tools are provided on both the left and right sides of the toolbox, offering operators more options for retrieving and placing tools. In actual trailer maintenance work, the working space around the trailer is often quite complex, and sometimes it is inconvenient to access tools from the front. In such cases, tools can be accessed from the openings on the left and right sides, making the use of the toolbox less restricted by surrounding obstacles or working positions, significantly improving the flexibility and convenience of toolbox use.

[0020] Door opening safety and stability: The limiting slide and limiting shaft in the door limiting assembly work together. During the opening and closing of the door, the limiting shaft always slides within the limiting slide, effectively limiting the door's movement trajectory and preventing it from shaking or swinging excessively. Simultaneously, the L-shaped limiting shaft groove at the end of the limiting slide allows the limiting shaft to engage when the door is opened to a specific position, further positioning and limiting the door. This prevents the door from accidentally sliding out and injuring personnel, ensuring the door's stability when retrieving tools and reducing safety risks caused by accidental door movement.

[0022] Figure 2 This is a schematic diagram of the structure of the sliding toolbox door for trailers proposed in this utility model. Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Referring to the figure, this embodiment provides a sliding toolbox for trailers, including:

[0025] Box 1 is used to store commonly used tools for trailer maintenance;

[0026] Box door 2 can be fastened to the opening of the box body;

[0027] Here, the top of the box is provided with a latch for easy locking of the box door, and the box door is correspondingly provided with a lock. The box door can be locked to the box body by locking the lock. One or more lugs for easy pulling of the box door can also be provided on the top of the box door (not shown in the figure, users can install and set them according to actual needs).

[0028] The door opening and closing mechanism includes a hinge shaft 3 fixedly installed on the side of the box body. A rotating connecting rod 4 is hinged to the hinge shaft 3, and the other end of the rotating connecting rod 4 is hinged to a hinge shaft 5 located on the side of the door 2.

[0029] In practical use, when it is necessary to open the door 2, the operator only needs to hold the upper lug of the door and gently pull it down. The rotating linkage will rotate around the hinge axis 3 as the door moves, allowing the door 2 to slide smoothly down and open along a specific trajectory until the door 2 is completely placed at the bottom of the box 1. The whole process is easy and convenient to operate, and the opening range is moderate, without taking up too much space. To close the door 2, push the door 2 in the opposite direction, rotate the linkage 4 to make the door 2 rise until the door 2 is locked at the opening of the box 1, and then lock the door with the lock.

[0030] Furthermore, the box 1 has openings for taking out tools on both the left and right sides, and the edges of the openings are rolled to prevent operators from being scratched when taking out tools.

[0031] Furthermore, the door opening and closing mechanism is also provided with a door limiting component, which includes a limiting slide 6 opened on the side of the door and a limiting shaft 7 fixedly installed on the bottom side of the box body. The limiting slide 6 and the limiting shaft 7 are slidably connected.

[0032] Furthermore, the end of the limiting slide 6 is provided with an L-shaped limiting shaft groove 8.

[0033] Here, when the door 2 is opened, the limiting slide 6 slides on the limiting shaft 7, effectively restricting the movement trajectory of the door 2, ensuring it can only slide along the direction of the slide 6, preventing the door from shaking or shifting. When the door is opened to its maximum position, under the action of gravity, the limiting shaft 7 slides into the L-shaped limiting shaft groove 8. The limiting shaft, locked in the groove, prevents the door from closing accidentally, providing a stable operating environment for the operator to retrieve tools. When closing the door 2, a slight force is needed to lift the door upwards to disengage the limiting shaft from the L-shaped limiting shaft groove, and then the door is pushed up to close. This design greatly improves the safety and stability during the opening and closing of the door.

[0034] Furthermore, the enclosure is made of high-strength, corrosion-resistant material to improve its service life and corrosion resistance.

[0035] Furthermore, a sealing strip is installed between the door and the body of the box to prevent dust, rainwater, and other contaminants from entering the box and to protect the internal tools.

[0036] The overall working principle of the above embodiments is as follows:

[0037] When the trailer door needs to be opened, the operator applies force to it. Since the door is hinged to one end of a rotating linkage via hinge shaft two, and the other end of the linkage is hinged to the trailer body via hinge shaft one, a movable linkage structure is formed. The operator's pulling force causes the door to move downwards, driving the rotating linkage to rotate around hinge shaft one. During rotation, the linkage pushes the door down a specific trajectory to open. For example, in routine trailer maintenance, the maintenance personnel can easily open the door by gently pulling down the door handle or lifting lug. Compared to traditional side-opening or top-opening doors, this sliding opening method is more convenient to operate in limited spaces, without worrying about the door occupying too much side or top space when open.

[0038] When closing the cabinet door, the operator applies force in the opposite direction, pushing the door upwards. At this time, the rotating linkage, driven by the door, rotates in the opposite direction around the hinge axis, causing the door to rise along the reverse trajectory from when it opened, until the door latches onto the cabinet opening, completing the closing action. This process is simple, direct, and convenient to operate, and ensures the door closes tightly, protecting the tools inside.

[0039] During the aforementioned operations, the openings on both sides of the toolbox provide operators with more angles for accessing and placing tools. When the space around the trailer is complex and tools cannot be easily accessed from the front, they can be taken from the side openings. For example, when the trailer is parked against a wall or other obstacles block the front opening, maintenance personnel can quickly obtain the necessary tools from the side openings, improving the flexibility and convenience of using the toolbox.

[0040] Door limiting principle: The limiting slide and limiting shaft in the door limiting assembly work together to limit the door's movement. During opening and closing, the limiting shaft slides within the limiting slide, restricting the door's trajectory and preventing it from wobbling or swinging excessively. When the door opens to the L-shaped limiting shaft groove at the end of the limiting slide, the limiting shaft slides into the groove, positioning and limiting the door to prevent accidental closure. To close the door, it must be slightly lifted to disengage the limiting shaft from the L-shaped groove before the door can be pushed up to close. This design ensures stable door opening while improving safety, preventing injury to operators or damage to tools.

[0041] Furthermore, if the box body is made of corrosion-resistant materials, such as aluminum alloy, it can effectively resist wind, rain, and chemical corrosion during trailer operation, extending the box body's service life. The sealing strip between the box door and the box body fills the gap between them, preventing dust, rainwater, and other impurities from entering the box and protecting tools from corrosion.

[0042] The above specific embodiments further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above are only specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be covered within the protection scope of this utility model.
