Description

Technical Field

[0001] This application relates to the field of enclosed box technology, specifically to an enclosed box that can resist deformation under stress. Background Technology

[0002] Collapsible boxes typically consist of three parts: a pallet, a box body, and a lid. They are assembled by stacking and are made up of one or more side panels. This structure not only gives collapsible boxes extremely high stackability and space utilization, but also makes them easy to disassemble and assemble.

[0003] Existing palletized crates can only serve the purpose of storing goods. Due to the relatively weak structural strength of the crate body, when the goods are unevenly distributed inside the crate (such as being too heavy on one side or having an irregular shape), the stress in some areas will far exceed the design value, while other areas will not be stressed enough, which will disrupt the structural balance and easily cause slight deformation of the crate body. When the deformation is too large, it is difficult to restore the original shape, affecting the normal storage and transportation of goods. Utility Model Content

[0004] In view of this, the purpose of this utility model is to overcome the shortcomings of the prior art by proposing a cladding box that can resist deformation under stress, so as to solve the problems existing in the prior art.

[0005] To achieve the above objectives, this utility model provides a collapsible box resistant to deformation under stress, comprising a pallet, a box body on the top of the pallet, a box cover detachably mounted on the top of the box body, a fixed platform fixedly connected to the outer surface of the pallet, a first recessed frame fixedly connected to the top of the fixed platform, a first frame shaft fixedly passing through the inner side of the first recessed frame, a swing plate rotatably connected to the outer surface of the first frame shaft, a pressure-resistant plate fixedly connected to the top of the swing plate, rubber nails provided on the inner side of the pressure-resistant plate, and a drive adjustment mechanism for controlling the position of the pressure-resistant plate provided on the fixed platform.

[0006] Preferably, the drive position adjustment mechanism includes a slide rail fixedly connected to the outer surface of the fixed platform, and a slide bracket slidably connected to the outer surface of the slide rail. The drive position adjustment mechanism can adjust the position of the pressure plate so that the pressure plate contacts and supports the position where the box body deforms at a suitable angle, thereby reducing the continued deformation of the box body during the storage of items.

[0007] Preferably, a screw is movably inserted through the inner side of the slide rail, and a plurality of screw holes are opened on the outer surface of the slide bracket, and the screw holes are threadedly connected to the screw.

[0008] Preferably, a second recess is fixedly connected to the top of the carriage, and a second frame shaft is fixedly passed through the inner side of the second recess.

[0009] Preferably, an electric actuator is rotatably connected to the outer surface of the second frame shaft, and a drive block is fixedly connected to the output end of the electric actuator.

[0010] Preferably, a concave plate is fixedly connected to the outer surface of the swing plate, and a plate shaft is fixedly inserted through the inner side of the concave plate, with the outer surface of the plate shaft rotatably connected to the inner surface of the drive block.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This collapsible box, which is resistant to deformation under stress, can move laterally along the slide rail via a sliding frame. The support points can be precisely adjusted according to the deformation position of the box, adapting to the problem of local pressure concentration caused by different cargo distributions. With the synchronous swinging and closing of two sets of concave anti-pressure plates, it forms a wrap-around support for the box, which not only disperses the pressure at a single point, but also enhances the overall torsional strength through the fit between the concave structure and the outer wall of the box, significantly improving the collapsible box's resistance to deformation under stress.

[0013] 2. This resistant-to-deformation box, when held in place by the pressure plate, provides strong friction without additional texture when the rubber nail surface contacts the box material, preventing the pressure plate from sliding or shifting and ensuring that the supporting force continues to act on the deformation area. At the same time, the elastic deformation capacity of the rubber nail can absorb the vibration and impact energy during transportation or stacking, reducing the direct impact of external forces on the box and lowering the risk of deformation.

Detailed Implementation

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] Please see Figure 1-4 A type of resistant deformation-resistant box includes a pallet 1, a box body 2 on the top of the pallet 1, a box cover 3 detachably installed on the top of the box body 2, a fixed platform 4 fixedly connected to the outer surface of the pallet 1, a first recessed frame 5 fixedly connected to the top of the fixed platform 4, a first frame shaft 6 fixedly passing through the inner side of the first recessed frame 5, a swing plate 7 rotatably connected to the outer surface of the first frame shaft 6, a pressure-resistant plate 8 fixedly connected to the top of the swing plate 7, the pressure-resistant plate 8 is concave in design and has two sets arranged symmetrically around the outer perimeter of the box body 2, rubber nails 9 are provided on the inner side of the pressure-resistant plate 8, the rubber nails 9 are made of rubber and have a certain cushioning effect, and a drive adjustment mechanism for controlling the position of the pressure-resistant plate 8 is provided on the fixed platform 4.

[0021] Through the above technical solution, the device can open the box cover 3 during use and place the items into the box 2. If the items are not evenly distributed in the box 2, it is easy to cause the box 2 to deform slightly. In order to prevent the box 2 from deforming to the point that it is difficult to restore its original shape, a drive position adjustment mechanism is designed to adjust the position of the pressure plate 8 so that it rests against the surface of the box 2 at a relatively appropriate angle, thereby preventing the box 2 from continuing to deform and improving the box's resistance to deformation.

[0022] Specifically, the drive position adjustment mechanism includes a slide rail 10 fixedly connected to the outer surface of the fixed platform 4, and a slide bracket 11 slidably connected to the outer surface of the slide rail 10.

[0023] Through the above technical solution, the slide 11 can slide along the surface of the slide rail 10, thereby adjusting the position of the second recess 14, and changing the angle adjustment range of the pressure plate 8 in conjunction with the extension and retraction of the electric push rod 16.

[0024] Specifically, a screw 12 is movably inserted through the inner side of the slide rail 10, and several screw holes 13 are opened on the outer surface of the slide bracket 11, and the screw holes 13 are threadedly connected to the screw 12.

[0025] Through the above technical solution, three sets of screw holes 13 are designed on both sides of the slide 11. When the screw 12 passes through the slide rail 10 and is stably connected to different screw holes 13, it can achieve the effect of adjusting the lateral position of the slide 11.

[0026] Specifically, a second recess 14 is fixedly connected to the top of the carriage 11, and a second frame shaft 15 is fixedly inserted through the inner side of the second recess 14.

[0027] Through the above technical solution, the second recess 14 cooperates with the second bracket shaft 15 to adapt to the angle deflection of the electric push rod 16 itself, because the electric push rod 16 will also have an angle deflection during the process of pushing and pulling the plate shaft 19 through the drive block 17.

[0028] Specifically, an electric actuator 16 is rotatably connected to the outer surface of the second shaft 15, and a drive block 17 is fixedly connected to the output end of the electric actuator 16.

[0029] Through the above technical solution, during the process of the electric actuator 16 pushing and pulling the plate shaft 19 through the drive block 17, the drive block 17 and the plate shaft 19 will rotate accordingly, thereby acting on the swing plate 7.

[0030] Specifically, a concave plate 18 is fixedly connected to the outer surface of the swing plate 7, and a plate shaft 19 is fixedly inserted through the inner side of the concave plate 18. The outer surface of the plate shaft 19 is rotatably connected to the inner surface of the drive block 17.

[0031] Through the above technical solution, after the plate shaft 19 is pushed or pulled, it will act on the swing plate 7 through the concave plate 18, thereby causing the swing plate 7 to rotate along the first frame shaft 6 to adjust the position of the pressure-resistant plate 8.

[0032] Working principle: During use, the lid 3 of the container can be opened to place items into the container 2. If the goods are unevenly distributed inside the container (e.g., one side is too heavy, or the shape is irregular), the stress in some areas will far exceed the design value, while other areas will not be stressed enough, disrupting the structural balance and easily causing slight deformation of the container 2. If the deformation is too large, it will be difficult to restore the original shape, affecting the normal storage and transportation of the goods. Therefore, the position of the slide 11 can be moved laterally according to the specific situation, that is, the slide 11 is moved along the slide rail. 10. Slide the slide rail 10 and insert the screw 12 into the corresponding screw hole 13 at the appropriate position to stabilize the slide 11 (during this process, the electric actuator 16 needs to extend and retract to a certain extent). Then, turn on the electric actuator 16. As the electric actuator 16 pushes the plate shaft 19 through the drive block 17 at the output end, its bottom will rotate along the second frame shaft 15. After the plate shaft 19 is pushed, it will act on the swing plate 7 through the concave plate 18, thereby causing the swing plate 7 to rotate along the first frame shaft 6. At the same time, As the swing plate 7 swings, the pressure-resistant plate 8 deflects synchronously until it is stuck on the outside of the box 2 and holds against the deformation point of the box 2. By applying appropriate pushing force, the box 2 can be prevented from deforming further. The rubber nails 9 on the inside of the pressure-resistant plate 8 have a high coefficient of friction, which means that even without additional texture or structure, the rubber nails 9 can provide excellent anti-slip effect. When the pressure-resistant plate 8 contacts the box 2, the rubber nails 9 can fit tightly against the surface of the box 2, effectively preventing the pressure-resistant plate 8 from sliding or shifting on the box 2, thereby ensuring the stability of the box 2. At the same time, due to the good elasticity of the rubber nails 9, they can absorb and disperse impact force. During transportation or stacking, the box 2 may be subjected to vibration or impact. The rubber nails 9 can play a buffering role, reducing the impact of these external forces on the box 2, thereby reducing the risk of deformation of the box 2. As the two sets of concave pressure-resistant plates 8 swing and approach synchronously, they can effectively resist the deformation of the entire box 2, further improving the box's resistance to deformation.

[0033] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
