Description

Technical Field

[0001] The utility model relates to the technical field of plastic packaging, and particularly relates to a PE hollow board box with a limiting structure. Background Art

[0002] There have emerged various storage devices with adjustable internal spaces in the existing market. Among them, the PE hollow board box with a limiting structure has received extensive attention due to its characteristics such as light weight, durability, cost-effectiveness, and recyclability. The PE hollow board is a composite material composed of two layers of thin films with a layer of foamed plastic in the middle, and has good impact resistance and heat insulation performance, and is suitable for making various packaging and storage containers.

[0003] However, although the PE hollow board box itself has certain advantages, there are still some limitations in practical applications. For example, the internal structure of the traditional PE hollow board box is fixed and cannot be flexibly adjusted according to the size and shape of the items, resulting in the inability to effectively utilize the internal space in some cases, or the inability to provide stable support and fixation for the items. In addition, when storing larger or special-shaped items, the traditional box may need to be disassembled or replaced, which not only increases the complexity of the operation but also reduces the work efficiency. Summary of the Utility Model

[0004] To solve the above technical problems, the utility model provides a PE hollow board box with a limiting structure.

[0005] The utility model is realized by the following technical solutions: A PE hollow board box with a limiting structure includes a box body. A sliding groove is provided on the inner wall of the box body, and a movable slider is slidably connected inside the sliding groove. A telescopic spring is fixedly connected to the lower surface of the movable slider.

[0006] Through the above technical solution, through the sliding connection between the sliding groove and the movable slider, the internal partition of the box body can be adjusted as needed, so as to adapt to the storage of items of different sizes or shapes, and improve the flexibility of use of the box.

[0007] As a further improvement of the above solution, the lower surface of the telescopic spring is fixedly connected to the inner bottom wall of the box body, and a positioning block is fixedly connected to the upper surface of the movable slider.

[0008] Through the above technical solution, combined with the elastic characteristics of the telescopic spring, the movable slider can freely move along the inner wall of the box body within a certain range, and this design increases the flexibility and adaptability of the system.

[0009] As a further improvement of the above solution, a limiting pressing plate is clamped on the surface of the positioning block.

[0010] Through the above technical solution, after the object is placed, the personnel slowly releases the limiting pressure block and no longer applies external force to it. As the limiting pressure block is released, the telescopic spring begins to contract, releasing the previously stored energy. The restoring force of the spring drives the movable slider and the positioning block to descend, and then drives the limiting pressure plate to move downward until the limiting pressure plate contacts the surface of the object, thereby pressing and fixing the object.

[0011] As a further improvement of the above solution, a connecting groove is provided on the upper surface of the limiting pressure plate.

[0012] Through the above technical solution, the opening of the connecting groove makes it convenient for personnel to disassemble and assemble the limiting pressure plate, and can provide an accurate position when installed with the positioning block.

[0013] As a further improvement of the above solution, the connecting groove is adapted to the positioning block.

[0014] Through the above technical solution, the design of the connection groove on the upper surface of the limit pressure plate and the positioning block can ensure that the limit pressure plate can be accurately installed in the predetermined position, providing stable support and positioning.

[0015] As a further improvement of the above solution, an observation window is provided on the outer surface of the box body.

[0016] Through the above technical solution, the setting of the observation window can facilitate personnel to observe the positioning of the object in the box in real time, ensuring the accuracy and safety of the operation.

[0017] As a further improvement of the above solution, an auxiliary handle is fixedly connected to the outer surface of the box body.

[0018] Through the above technical solution, the auxiliary handle provides an additional gripping point, making it more convenient to carry or move the box body and reducing hand fatigue. When operating or transporting the box body, the auxiliary handle can help the user better control the balance and prevent slipping or tipping.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] The utility model provides a limit pressure plate. When the user needs to place an object, the limit pressure plate is manually stretched to move it upward along the sliding groove. At this time, the telescopic spring is stretched to store elastic potential energy. Due to the rising phenomenon of the limit pressure plate, the height inside the box body increases, creating more space for placing objects. Once the limit pressure plate is released, the telescopic spring begins to rebound naturally, driving the movable slider, the positioning block and the limit pressure plate connected thereto to move downward, and come into close contact with the surface of the object in the box body. The restoring force of the spring and the limit pressure block exert pressure on the object to achieve limited clamping of the object and prevent it from shaking or shifting during transportation.

[0028] Next, in combination with the accompanying drawings and specific implementation manners, the present utility model will be further described. It should be noted that, on the premise of no conflict, the following-described embodiments or technical features can be arbitrarily combined to form new embodiments.

[0029] Embodiment:

[0030] Please combine Figures 1-5 , a PE hollow board box with a limit structure in this embodiment includes a box body 1. A sliding groove 2 is opened on the inner wall of the box body 1. A movable slider 3 is slidably connected inside the sliding groove 2. A telescopic spring 4 is fixedly connected to the lower surface of the movable slider 3. Through the sliding connection between the sliding groove 2 and the movable slider 3, the internal partition of the box body 1 can be adjusted as needed, so as to adapt to the storage of items of different sizes or shapes, and improve the flexibility of use of the box.

[0031] The lower surface of the telescopic spring 4 is fixedly connected to the inner bottom wall of the box body 1. A positioning block 5 is fixedly connected to the upper surface of the movable slider 3. Combining with the elastic characteristics of the telescopic spring 4, the movable slider 3 can freely move along the inner wall of the box body 1 within a certain range. This design increases the flexibility and adaptability of the system.

[0032] The surface of the positioning block 5 is engaged with the limiting pressure plate 6. After the object is placed, the staff first slowly releases the control of the limiting pressure block 6 to change it from a stressed state to a free state. This action triggers the telescopic spring 4 in the device. The spring was originally in a compressed state and accumulated a certain amount of elastic potential energy. As the limiting pressure block 6 is released, the spring begins to rebound naturally, gradually converting its internal energy into power, driving the movable slider 3 and the positioning block 5 to move downward along a predetermined trajectory. In this process, the movement of the movable slider 3 and the positioning block 5 does not occur independently. The positioning block 5 is connected to the limiting pressure plate 6 through the connecting groove 7, forming a linkage mechanism together. Therefore, as the movable slider 3 and the positioning block 5 move downward, the limiting pressure plate 6 is also synchronously pulled and pushed downward in the vertical direction. Finally, the limiting pressure plate 6 reaches the end of its stroke and is in close contact with the surface of the object to be fixed. At this time, the restoring force of the spring and the momentum of the movable slider 3 work together to make the limiting pressure plate 6 apply sufficient pressure to the object, thereby achieving a stable clamping of the object.

[0033] The upper surface of the limiting pressure plate 6 is provided with a connecting groove 7, which makes it convenient for personnel to disassemble and assemble the limiting pressure plate 6. When personnel place objects, if they find that the limiting pressure plate 6 blocks the space inside the box body 1, they can pull the positioning block 5 upwards and then move the limiting pressure plate 6 downwards to disengage the connecting groove 7 from the positioning block 5, and then the limiting pressure plate 6 can be taken out. Personnel can place some large objects inward. After placement, stretch the positioning block 5 again and align the connecting groove 7 on the upper surface of the limiting pressure plate 6 with the positioning block 5 to complete the installation.

[0034] The connecting groove 7 is adapted to the positioning block 5. The design of the connecting groove 7 on the upper surface of the limiting pressure plate 6 and the positioning block 5 being adapted to each other can ensure that the limiting pressure plate 6 can be accurately installed in the predetermined position, providing stable support and positioning.

[0035] An observation window 8 is provided on the outer surface of the box body 1. The observation window 8 is usually made of a transparent material, such as glass or transparent plastic, to ensure that external light can penetrate into the interior so that the internal situation can be seen.

[0036] An auxiliary handle 9 is fixedly connected to the outer surface of the box body 1. The auxiliary handle 9 provides an additional gripping point, making it more convenient to carry or move the box body 1 and reducing hand fatigue. When operating or transporting the box body 1, the auxiliary handle 9 can help the user better control the balance and prevent slipping or tipping.

[0037] In the embodiment of the present application, the implementation principle of a PE hollow board box with a limiting structure is as follows: The user manually stretches the limiting pressure plate 6, which moves upward along the sliding groove 2 through the cooperation of the positioning block 5 and the movable slider 3. During this process, the telescopic spring 4 is stretched and stores elastic potential energy. At this time, the height inside the box body 1 increases and the space expands, allowing personnel to place objects inside. After the objects are placed, the staff first slowly releases the control of the limiting pressure block 6, causing it to change from a stressed state to a free state. This action triggers the telescopic spring 4 inside the device. The spring was originally in a compressed state and had accumulated a certain amount of elastic potential energy. With the release of the limiting pressure block 6, the spring begins to naturally rebound, gradually converting the energy inside it into power, driving the movable slider 3 and the positioning block 5 to move downward along the established trajectory. During this process, the movements of the movable slider 3 and the positioning block 5 do not occur independently. The positioning block 5 is connected to the limiting pressure plate 6 through the connecting groove 7, forming a linkage mechanism together. Therefore, as the movable slider 3 and the positioning block 5 move downward, the limiting pressure plate 6 is also synchronously pulled and advanced downward along the vertical direction. Finally, the limiting pressure plate 6 reaches the end of its stroke and is in close contact with the surface of the object to be fixed. At this time, the restoring force of the spring and the momentum of the movable slider 3 act together, causing the limiting pressure plate 6 to exert sufficient pressure on the object, achieving stable clamping of the object and preventing the object from shaking and shifting inside the box body 1. When personnel are placing objects and find that the presence of the limiting pressure plate 6 blocks the space inside the box body 1, making it difficult to place objects, the user can first pull the positioning block 5 upward and then move the limiting pressure plate 6 downward to disengage the connecting groove 7 from the positioning block 5, thereby removing the limiting pressure plate 6. After placing large-sized objects, the user stretches the positioning block 5 again, aligns the connecting groove 7 on the upper surface of the limiting pressure plate 6 with the positioning block 5, and completes the reinstallation of the limiting pressure plate 6.

[0038] The above embodiments are only the preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention belong to the scope of protection required by the present invention.
