Description

Technical Field

[0001] This utility model relates to the field of logistics turnover box technology, and in particular to a logistics turnover box with a reinforced structure. Background Technology

[0002] Logistics turnover boxes are containers used for the transportation, storage, and turnover of goods, and are widely used in logistics, warehousing, and supply chain management. They are typically made of high-strength, durable materials such as plastics, metals, or composite materials, possessing strong resistance to pressure and impact to ensure the safety of goods during transportation. The design of logistics turnover boxes usually takes into account the ease of stacking and storage; most are stackable, facilitating space saving and improving storage efficiency.

[0003] To address the aforementioned problems, Chinese Patent (Publication No. CN 216762534 U) discloses an environmentally friendly logistics turnover box with corner reinforcement structure. The box includes a box body with several lower corner edgings at the bottom, located at the four corners of the box body's bottom. Each lower corner edging has side reinforcement edgings. Upper corner edgings are tightly fitted onto the outer surfaces of the box body and the side reinforcement edgings. A cushioning pad is provided on the inner wall surface of the lower corner edgings. Both the inner surfaces of the side reinforcement edgings and the upper corner edgings have anti-slip and wear-resistant layers, which are tightly adhered to the outer surface of the box body. This invention effectively protects and reinforces the relevant corners of the logistics turnover box, making the corners less prone to deformation and damage, improving the load-bearing capacity and recycling rate of the logistics turnover box, and is more economical and environmentally friendly.

[0004] This solution effectively solves the problem of easily deformed and damaged corners of traditional logistics turnover boxes by setting up bottom corner edging, side reinforcement edging, top corner edging, and a combination of protrusions and locking holes. It enhances corner protection and support, improves load-bearing capacity and recyclability, and the structure is easy to assemble and disassemble, adaptable to logistics turnover boxes of different lengths and widths. However, its edging reinforcement structure is a fixed-size design, lacking height adjustability, and cannot match logistics turnover boxes of different heights, thus limiting its applicability.

[0005] In view of the above, it is necessary to improve the existing technology to solve the above problems. Utility Model Content

[0006] The present invention is intended to provide a solution to the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A logistics turnover box with a reinforced structure includes a box body, a lower corner edging, and an upper corner edging. A first slider and a second slider are connected to the sidewall of the box body. The first slider is located above the second slider. The upper corner edging is slidably connected to the first slider, and the lower corner edging is slidably connected to the second slider. A base plate is connected to the lower corner edging, and a sleeve is connected to the lower corner edging. The sleeve has a receiving groove with an L-shaped cross-section. Several second limiting holes are formed on the sidewall of the receiving groove. A sliding tube is connected to the upper corner edging and is slidably connected to the receiving groove. The sliding tube has an installation groove, and a first limiting hole is formed on the sidewall of the installation groove. A positioning spring is connected to the inner wall of the installation groove, and a positioning protrusion is connected to the positioning spring. The positioning protrusion matches the first and second limiting holes.

[0009] Preferably, the positioning spring is U-shaped and is fixedly connected to a spring.

[0010] Preferably, the lower corner bezel has a fixing groove, and the upper corner bezel is fixedly connected with a blocking protrusion, wherein the fixing groove and the blocking protrusion are matched with each other.

[0011] Preferably, both the blocking protrusion and the fixing groove have an L-shaped cross-section.

[0012] Preferably, the cross-sections of the first limiting groove, the slider, and the second limiting groove are all trapezoidal.

[0013] The beneficial effects of this technical solution compared to existing technologies are as follows:

[0014] (1) By sliding the upper corner edging with the first slider and the lower corner edging with the second slider, as well as the cooperation structure of the slide tube and the sleeve, the height adjustment of the reinforced edging can be realized, which can adapt to logistics turnover boxes of different heights and significantly expand the scope of application.

[0015] (2) The design of U-shaped positioning spring combined with spring makes the positioning protrusion more stable and reliable in conjunction with the first limit hole and the second limit hole. It provides elastic buffer during the adjustment process to avoid structural damage caused by rigid collision. At the same time, it ensures that the limit is not easy to loosen, thus improving the durability and ease of operation of the reinforced structure.

[0016] (3) The fixing groove of the lower corner edging and the blocking protrusion of the upper corner edging adopt an L-shaped matching structure to form a multi-directional limiting effect. When stacked or subjected to external force impact, it effectively prevents the edging from misaligning or separating from the box, further enhancing the tightness and deformation resistance of the corner reinforcement.

[0017] (4) Both the blocking protrusion and the fixing groove cross-section adopt an L-shaped matching design. When stacking, the multi-directional limiting and locking of the L-shaped folded edge allows the interlocking contact surface of the upper and lower edges to cover the horizontal and vertical directions at the same time, effectively suppressing the lateral displacement caused by shaking during stacking or transportation, and improving the stacking stability and anti-tilting ability of the box.

[0018] (5) The slider and limiting groove structure with trapezoidal cross section utilizes the inclined plane self-locking principle to enhance the stability of the sliding connection and prevent the slider from accidentally shifting during transportation vibration. Attached Figure Description

[0025] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0026] like Figure 1 The logistics turnover box with a reinforced structure shown includes a box body 1, lower corner edging 2, and upper corner edging 3, as shown. Figure 5 As shown, the four side walls of the housing 1 are connected to a first slider 9 and a second slider 17, with the first slider 9 positioned above the second slider 17, as shown. Figure 1 and Figure 2As shown, the upper corner edging 3 is provided with a second limiting groove 10 that is slidably connected to the first slider 9, and the lower corner edging 2 is provided with a first limiting groove 8 that is slidably connected to the second slider 17. The limiting grooves and sliders are matched with each other, that is, the sliders can be embedded in the limiting grooves. A base plate 11 is connected to the bottom side wall of the lower corner edging 2, and a sleeve 5 is connected to the top of the corner of the lower corner edging 2. The sleeve 5 is provided with a receiving groove 18. The cross-section of both the sleeve 5 and the receiving groove 18 is L-shaped. Several second limiting holes 7 are opened on the two side walls of the receiving groove 18. A sliding tube 4 is connected to the upper corner edging 3, such as... Figure 3 As shown, the slide tube 4 is slidably connected to the receiving groove 18. The slide tube 4 is provided with a mounting groove 19. The mounting groove 19 has first limiting holes 6 on both sides. A positioning spring 12 is fixedly connected to the inner wall of the mounting groove 19. One end of the positioning spring 12 is connected to a positioning protrusion 13. The two sides of the positioning protrusion 13 are arc-shaped transitions. The longitudinal section of the positioning spring 12 is U-shaped. The two ends of the positioning spring 12 are connected to the two ends of the spring 14. The positioning protrusion 13 matches the first limiting hole 6 and the second limiting hole 7. That is, the positioning protrusion 13, the first limiting hole 6 and the second limiting hole 7 are aligned. The two limiting holes have the same diameter. Press the positioning protrusion 13 to separate it from the second limiting hole 7 on the side wall of the sleeve 5. That is, by pressing, the positioning protrusion 13 is retracted into the mounting groove 19 of the slide tube 4. Then, push or pull the slide tube 4 up or down to complete the height adjustment of the device. When the height matching the housing 1 is reached, the positioning protrusion 13 will re-enter the second limiting hole 7 under the rebound force of the spring 14 and the positioning spring 12. The side wall of the positioning protrusion 13 will abut against the side wall of the second limiting hole 7 again to complete the fixation.

[0027] The upper corner edging 3 is connected to 15, and the lower corner edging 2 is connected to a fixing groove 16. The blocking protrusion 15 and the fixing groove 16 match each other. When stacking, align the positioning groove 16 of the other box 1 with the blocking protrusion 15 of the lower box, and then insert it to make the two boxes stacked, avoiding the two boxes from shaking or relative displacement.

[0028] The specific implementation process is as follows:

[0029] The worker first aligns the first limiting groove 8 at the bottom of the lower corner edging 2 with the second slider 17 on the side wall of the housing 1, and pushes it downwards vertically until the second slider 17 is fully embedded in the first limiting groove 8 on the side wall of the corner edging 2. Then, the worker aligns the second limiting groove 10 of the upper corner edging 3 with the first slider 9 on the top of the housing 1 and pushes it downwards vertically, completing the initial assembly of the edging and the housing. When it is necessary to adapt to housings of different heights, the worker presses down on the positioning protrusions 13 on both sides of the slide tube 4 with both hands. The U-shaped positioning spring 12 compresses the spring 14, causing the protrusions to disengage from the second limiting hole 7 on the side wall of the sleeve 5. At this time, the slide tube 4 slides up and down along the receiving groove 18, causing the upper corner edging 3 to rise and fall synchronously. After adjusting to the target height, the worker releases both hands, and the spring 14 rebounds, pushing the positioning spring 12 back to its original position, so that the positioning protrusion 13 simultaneously engages in the first limiting hole 6 of the slide tube 4 and the corresponding second limiting hole 7 of the sleeve 5, completing the height locking.

[0030] During stacking, the worker needs to align the L-shaped fixing groove 16 of the lower corner edge 2 of the upper box with the L-shaped blocking protrusion 15 of the upper corner edge 3 of the lower box, and slowly press down vertically. The bidirectional limiting of the L-shaped folded edge achieves horizontal anti-slip and vertical anti-detachment. At the same time, the first slider 9 and the second limiting groove 10 of the trapezoidal cross section cancel out vibration displacement through inclined self-locking. The entire assembly process does not require special tools, and the worker can judge the limiting status through tactile feedback, which greatly improves the operation efficiency.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solution of this utility model.
