Description

Technical Field

[0001] The utility model relates to the technical field of hollow panel boxes, in particular to a hollow panel box with anti-extrusion function. Background Art

[0002] The hollow panel box, the plastic hollow panel box is a new type of packaging material, produced by PP material, non-toxic, odorless, moisture-proof, corrosion-resistant, light in weight, gorgeous in appearance, rich and pure in color, and has high flexural resistance, anti-aging, tensile, compressive, and tear strength. The products are widely used in the product sales, transportation, and turnover processes of industries such as machinery, hardware, electronics, pesticides, advertising, and decoration.

[0003] The existing hollow panel boxes generally have poor anti-extrusion ability. When being extruded, the side walls of the hollow panel box are easily cracked, resulting in the deformation and damage of the hollow panel box and the damage of the items inside the box. Most of the box lids of the box are directly covered on the box body, and the middle of the box lid is suspended with insufficient supporting force. When the box is subjected to vertical extrusion force, the middle part of the box lid is easily deformed downward, producing a depression, and the box lid squeezes the items inside the box from above, easily damaging the internal items. Summary of the Invention

[0004] In order to solve the above problems, the utility model provides a hollow panel box with anti-extrusion function to more precisely solve the above problems.

[0005] The utility model is realized through the following technical solutions:

[0006] The utility model provides a hollow panel box with anti-extrusion function, including a box body. The upper surface of the box body is provided with a box lid. The bottom of the box body is fixedly connected with a plurality of lower reinforcing plates. All the lower reinforcing plates are perpendicular to each other and fixedly connected to each other. The lower surface of the box lid is fixedly connected with a plurality of upper reinforcing plates. All the upper reinforcing plates are fixedly connected to each other. Both sides of each lower reinforcing plate are fixedly connected with vertical anti-extrusion plates. A plurality of anti-extrusion plates are fixedly connected to different sides of the box body.

[0007] Further, two square notches are provided on the lower surface of all the upper reinforcing plates. The size and depth of the square notches correspond to those of the anti-extrusion plates. The positions of the upper reinforcing plates and the lower reinforcing plates are opposite.

[0008] Further, the length of the upper reinforcing plate is the sum of the length of the lower reinforcing plate and the thicknesses of the anti-extrusion plates on both sides.

[0009] Further, a plurality of card slots are provided on the four sides of the box body. The number of card slots is the same as the number of anti-extrusion plates, located on one side of the anti-extrusion plates. The width of the card slots is the same as the width of the anti-extrusion plates, and the height of the card slots is the same as the height of the square notches.

[0010] Further, a fixing ring is fixedly connected to the outer side of all the pressure - resistant plates. The fixing ring is located at the middle part of the pressure - resistant plate. Four vertical rods are fixedly connected to the lower surface of the fixing ring. The lower ends of the vertical rods are fixedly connected to a protective shell, and the protective shell covers the four corners under the plate box body.

[0011] Further, the two ends of the upper reinforcing plate correspond to the pressure - resistant plates. A clamping component is arranged between the two sides of the upper reinforcing plate and the pressure - resistant plates. The clamping component is located at the side walls of the square notch facing both sides.

[0012] Further, the clamping component includes a sliding rod. Slide holes are arranged at the side walls of the square notch facing both sides. The sliding rod is located in the slide hole and is slidably connected to the upper reinforcing plate. A spring is fixedly connected between the sliding rod and the side wall of the slide hole. One end of the sliding rod away from the slide hole is provided with an arc surface, and an arc - shaped groove is arranged on one side of the pressure - resistant plate close to the upper reinforcing plate.

[0013] Further, an arc - shaped clamping block is fixedly connected to the side wall of the arc - shaped groove. A groove is arranged at one end of the sliding rod with an arc surface, and a fixing block is fixedly connected in the groove. An inner arc surface is arranged on the side of the fixing block facing the outside, and the inner arc surface is matched with the arc - shaped clamping block.

[0014] Further, the arc - shaped clamping block and the fixing block are made of magnets, and the upper reinforcing plate, the lower reinforcing plate and the pressure - resistant plate are made of engineering plastics.

[0015] The beneficial effects of the present utility model:

[0016] For a hollow plate box with anti - extrusion proposed by the present utility model, by setting the upper reinforcing plate, the lower reinforcing plate and the pressure - resistant plates, when the box cover is covered on the plate box body, the upper reinforcing plate is clamped into the clamping groove on the plate box body, which can prevent the separation of the plate box body and the box cover. The clamping groove plays a positioning role. At this time, the square notch on the upper reinforcing plate fits with the pressure - resistant plates, so that the weight of the box cover is pressed on multiple pressure - resistant plates. When a downward pressure is applied above the box cover, the pressure and the gravity of the box cover and the upper reinforcing plate directly act on the pressure - resistant plates and will not act on the plate box body, providing buffering and protection for the plate box body and greatly improving the anti - pressure ability of the plate box body in the vertical direction.

[0017] For a hollow plate box with anti - extrusion, by setting the clamping component, the arc surface at one end of the sliding rod contacts the pressure - resistant plate, and the sliding rod slides into the slide hole to avoid, and the spring is compressed. When the sliding rod aligns with the arc - shaped groove, the spring pushes the sliding rod into the arc - shaped groove, and the arc - shaped clamping block is clamped onto the inner arc surface on one side of the fixing block. When it is necessary to separate the box cover, just push the box cover upward forcefully from the side of the box cover, so that the arc - shaped clamping block is separated from the sliding rod. During the separation process, the sliding rod still slides continuously to avoid until the sliding rod disengages from the arc - shaped groove. When covering the box cover, press downward, and when opening the box cover, lift it forcefully. The operation is simple. Description of the Drawings

Specific embodiments

[0025] In order to more clearly and completely illustrate the technical solution of the present utility model, the present utility model will be further described below with reference to the accompanying drawings.

[0026] Please refer to Figures 1-6, the present utility model proposes a hollow board box that resists extrusion, including a board box body 1. A box cover 2 is provided on the upper surface of the board box body 1. A plurality of lower reinforcing plates 3 are fixedly connected to the bottom of the board box body 1. All the lower reinforcing plates 3 are perpendicular to each other and fixedly connected to each other. A plurality of upper reinforcing plates 4 are fixedly connected to the lower surface of the box cover 2. All the upper reinforcing plates 4 are fixedly connected to each other. Vertical anti-pressure plates 5 are fixedly connected to both sides of each lower reinforcing plate 3. A plurality of anti-pressure plates 5 are fixedly connected to different sides of the board box body 1. Two square notches 6 are provided on the lower surface of all the upper reinforcing plates 4. The size and depth of the square notches 6 correspond to those of the anti-pressure plates 5. The positions of the upper reinforcing plates 4 and the lower reinforcing plates 3 are opposite. The length of the upper reinforcing plate 4 is the sum of the length of the lower reinforcing plate 3 and the thicknesses of the anti-pressure plates 5 on both sides. A plurality of card slots 7 are provided on the four sides of the board box body 1. The number of card slots 7 is the same as the number of anti-pressure plates 5, and the position is on one side of the anti-pressure plate 5. The width of the card slot 7 is the same as the width of the anti-pressure plate 5, and the height of the card slot 7 is the same as the height of the square notch 6. The bottom of the board box body 1 is provided with lower reinforcing plates 3, and the side walls are provided with anti-pressure plates 5. The anti-pressure plates 5 can resist the impact from the side of the board box body 1, greatly enhancing the compressive performance of the board box body 1 and preventing the side walls of the board box body 1 from deforming and squeezing towards the middle. The board box body 1 and the box cover 2 are separately provided. The positions of the upper reinforcing plates 4 and the lower reinforcing plates 3 correspond and have the same width. When the box cover 2 is covered on the board box body 1, the upper reinforcing plates 4 are inserted into the card slots 7 on the board box body 1, which can prevent the board box body 1 and the box cover 2 from separating. The card slots 7 play a positioning role. At this time, the square notches 6 on the upper reinforcing plates 4 are attached to the anti-pressure plates 5, so that the weight of the box cover 2 is pressed on the plurality of anti-pressure plates 5. When a downward pressure is applied above the box cover 2, the pressure and the gravity of the box cover 2 and the upper reinforcing plates 4 directly act on the anti-pressure plates 5 and will not act on the board box body 1, providing buffering and protection for the board box body 1 and greatly improving the vertical compressive resistance of the board box body 1.

[0027] As Figure 4 shown in Figure 6 , fixing rings 8 are fixedly connected to the outer sides of all the anti-pressure plates 5. The fixing rings 8 are located in the middle of the anti-pressure plates 5. Four vertical rods 9 are fixedly connected to the lower surface of the fixing rings 8. The lower ends of the vertical rods 9 are fixedly connected to protective shells 10. The protective shells 10 cover the four corners at the lower part of the board box body 1. The fixing rings 8 fix all the anti-pressure plates 5 and provide support for the anti-pressure plates 5 to prevent the anti-pressure plates 5 from deforming or skewing. The four corners at the lower part of the board box body 1 are covered by the protective shells 10 to prevent excessive wear at the four corners of the board box body 1. The corners of the board box body 1 are areas prone to wear. By providing the protective shells 10, the wear speed is slowed down. At the same time, the bottom of the board box body 1 is lifted by the lower reinforcing plates 3, reducing the wear at the bottom of the board box body 1.

[0028] As Figure 2 shown in Figure 3As shown, the two ends of the upper reinforcing plate 4 correspond to the anti-pressure plates 5, and a clamping assembly 11 is provided between the two sides of the upper reinforcing plate 4 and the anti-pressure plates 5. The clamping assembly 11 is located at the side walls of the square notch 6 facing both sides. When the box cover 2 is covered on the board box body 1, the square notch 6 on the upper reinforcing plate 4 is fitted with the anti-pressure plates 5. After fitting, the clamping assembly 11 between the side wall of the square notch 6 and the anti-pressure plates 5 fixes the anti-pressure plates 5 and the upper reinforcing plate 4, so that the box cover 2 is fixed on the board box body 1. When transporting objects, the box cover 2 is prevented from easily detaching from the board box body 1, causing the items in the board box body 1 to be lost.

[0029] like Figure 2 and Figure 3 As shown, the clamping assembly 11 includes a sliding rod 111, and sliding holes are provided at the side walls on both sides of the square notch 6. The sliding rod 111 is located in the sliding hole, and the sliding rod 111 is slidably connected to the upper reinforcing plate 4. A spring 112 is fixedly connected between the sliding rod 111 and the side wall of the sliding hole. An arc surface is provided at the end of the sliding rod 111 away from the sliding hole, and an arc groove 113 is provided on the side of the anti-pressure plate 5 close to the upper reinforcing plate 4. The side wall of the arc groove 113 is fixedly connected to the arc block 12, and a groove is provided at the end of the sliding rod 111 with the arc surface, and a fixing block 13 is fixedly connected in the groove. The fixing block 13 is provided with an inner arc surface on the side facing the outside, and the inner arc surface cooperates with the arc block 12. In the process of the square notch 6 on the upper reinforcing plate 4 fitting with the anti-pressure plate 5, the sliding The arc surface at one end of the rod 111 contacts the anti-pressure plate 5, and the sliding rod 111 slides into the sliding hole to avoid it, and the spring 112 is compressed. When the sliding rod 111 is aligned with the arc groove 113, the spring 112 pushes the sliding rod 111 into the arc groove 113. When encountering the arc block 12, the sliding rod 111 slides in the opposite direction to avoid it again until the arc block 12 is stuck in the inner arc surface of one side of the fixed block 13. When it is necessary to separate the box cover 2, you only need to push the box cover 2 upward from the side of the box cover 2 to disengage the arc block 12 from the sliding rod 111. During the disengagement process, the sliding rod 111 continues to slide and avoid it until the sliding rod 111 disengages from the arc groove 113. When closing the box cover 2, press down, and when opening the box cover 2, lift it up with force. The operation is simple.

[0030] like Figure 3 As shown, the arc-shaped card block 12 and the fixed block 13 are made of magnets, and the upper reinforcing plate 4, the lower reinforcing plate 3 and the anti-pressure plate 5 are made of engineering plastics. When the box cover 2 is closed, the arc-shaped card block 12 is inserted into the inner arc surface of one side of the fixed block 13, and the adsorption force between the arc-shaped card block 12 and the fixed block 13 is increased by magnetic force, so that the box cover 2 is more firmly covered on the box body 1.

[0031] Working principle: A lower reinforcement plate 3 is provided at the bottom of the box body 1, and a pressure-resistant plate 5 is provided on the side wall. The pressure-resistant plate 5 can resist the impact from the side of the box body 1. When the box cover 2 is covered on the box body 1, the upper reinforcement plate 4 is snapped into the card slot 7 on the box body 1. The square notch 6 on the upper reinforcement plate 4 fits with the pressure-resistant plate 5. During the fitting process, the arc surface at one end of the sliding rod 111 contacts the pressure-resistant plate 5, and the sliding rod 111 slides into the sliding hole to make way, and the spring 112 is compressed. When the sliding rod 111 is aligned with the arc-shaped groove 113, the spring 112 pushes the sliding rod 111 into the arc-shaped groove 113. When encountering the arc-shaped clamping block 12, the sliding rod 111 slides in the reverse direction again to make way until the arc-shaped clamping block 12 is snapped into the inner arc surface on one side of the fixed block 13. When it is necessary to separate the box cover 2, just push the box cover 2 upward forcefully from the side of the box cover 2 to make the arc-shaped clamping block 12 disengage from the sliding rod 111. The fixing ring 8 fixes all the pressure-resistant plates 5 to provide support for the pressure-resistant plates 5. The four corners below the box body 1 are covered by the protective shells 10.

[0032] Certainly, the present utility model can also have many other implementation manners. Based on this implementation manner, other implementation manners obtained by ordinary technical personnel in the field without any creative labor belong to the scope protected by the present utility model.
