A packaging box with pressure resistance

Abstract

This utility model discloses a packaging box with a pressure-resistant function, including a packaging box with side handles on both sides and side lifting handles installed on both outer walls of the packaging box. Pressure-resistant devices are installed at each of the four corners of the packaging box, and alignment blocks are installed at the bottom of the packaging box. A lower base is provided inside each pressure-resistant device, and a plurality of side slide rails are installed on the upper surface of the lower base. Compression springs are installed between the side slide rails, and anti-deviation guards are fixed on the lower base. Slider blocks are installed on the plurality of side slide rails. Through the pressure-resistant devices installed at each of the four corners of the packaging box, the force is distributed to the top blocks with rods at the four corners during stacking. With the auxiliary vertical displacement of the fixing blocks, the sliders slide down the side slide rails under pressure, compressing the compression springs. With the assistance of the compression springs, the top blocks with rods are supported. Therefore, when packaging boxes are stacked, the downward pressure is supported, achieving the pressure-resistant function and preventing the top of the packaging box from cracking under pressure.

Description

Technical Field

[0001] This utility model relates to the field of packaging box technology, specifically a packaging box with pressure resistance function. Background Technology

[0002] Packaging boxes are containers used to protect, transport, and store goods. They are usually made of corrugated cardboard, plastic, or wood. They are designed to be sturdy and durable, effectively preventing damage to goods from collisions, squeezing, or moisture during transportation. They are suitable for various industries such as electronics, food, and daily necessities.

[0003] Currently, existing packaging boxes generally support other packaging boxes directly through the box body. This can cause some heavier packaging boxes to be stacked on top of lighter packaging boxes, which can put pressure on the surface of the packaging boxes and make them prone to cracking at the top. Therefore, there is a need for packaging boxes with pressure resistance to change this situation. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a packaging box with pressure resistance. By installing pressure-resistant devices at all four corners of the packaging box, the force is distributed to the top blocks with rods at the four corners during stacking. Combined with the auxiliary vertical displacement of the fixing blocks, the packaging boxes can be supported by downward pressure when stacked, thus achieving pressure resistance.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a packaging box with pressure resistance, comprising a packaging box with side handles on both sides, side lifting handles installed on both outer walls of the packaging box, pressure-resistant devices installed at the four corners of the packaging box, and alignment blocks installed at the bottom of the packaging box; a lower base is provided inside the pressure-resistant devices, a plurality of side slide rails are installed on the upper surface of the lower base, compression springs are installed between the side slide rails, anti-deviation guards are fixed on the lower base, sliders are installed on the plurality of side slide rails, a fixing block is installed above the sliders, a slot is formed above the fixing block, and a rod-mounted top block passes through the fixing block. The rod-mounted top block is mainly supported by the slider below, and the bottom of the slider is supported by a compression spring, so that when pressure is applied, the force is indirectly transmitted to the compression spring, providing a certain pressure resistance.

[0006] Furthermore, the bottom of the rod-mounted top block is fixed to the surface of the slider, the slider slides in conjunction with the side slide rail, the rod-mounted top block is engaged in the slot, and the bottom of the slider is fixed to the top of the compression spring. The side slide rail mainly slides in conjunction with the slider, and the slider transmits pressure to the rod-mounted top block, engaging it in the slot to distribute the pressure on the top of the packaging box.

[0007] Furthermore, the anti-deviation guard is located on the outside of the compression spring. The lower base, the side slide rail, and the fixing block are all fixed to the outer wall of the packaging box. The alignment block is used to engage with another packaging box. The alignment block is mainly installed at the bottom of the packaging box. By using the alignment block, the surface of another packaging box can be accurately aligned and engaged. When engaged, the compression spring will be subjected to force, which, with the assistance of the anti-deviation guard, prevents the compression spring from deviating outward.

[0008] Furthermore, the slider is triggered by the rod top block, and the slider is supported below by the compression spring.

[0009] Furthermore, the packaging box is made of one piece of plastic and has a built-in through groove for drainage or ventilation.

[0010] Beneficial effects

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

[0012] This invention utilizes anti-compression devices installed at all four corners of the packaging box. During stacking, the force is distributed to the top blocks with rods at the four corners. With the assistance of the fixed blocks and vertical displacement, the slider slides down the side rail under pressure, compressing the compression spring. With the assistance of the compression spring, the top blocks with rods are supported. Thus, when packaging boxes are stacked, the downward pressure is supported, achieving an anti-compression function and preventing the top of the packaging box from cracking under pressure.

Figure 3 This is a three-dimensional enlarged structural diagram of the pressure-resistant device of this utility model.

[0021] This utility model provides a packaging box with pressure resistance function, including a packaging box 1, side handles 2 on both sides of the packaging box 1, side lifting handles 3 on both outer walls of the packaging box 1, pressure resistance devices 12 installed at the four corners of the packaging box 1, and alignment blocks 11 installed at the bottom of the packaging box 1; a lower base 121 is provided inside the pressure resistance device 12, a plurality of side slide rails 125 are installed on the upper surface of the lower base 121, a compression spring 123 is installed between the side slide rails 125, an anti-deviation guard 122 is fixed on the lower base 121, a slider 124 is installed on the plurality of side slide rails 125, a fixing block 126 is installed above the slider 124, a slot 127 is formed above the fixing block 126, and a rod-mounted top block 128 passes through the fixing block 126.

[0022] The working principle of this utility model is explained below:

[0023] This utility model, by setting the packaging box 1 in a designated position, can be assisted by a side handle or a side table handle 3 to lift the packaging box 1 with combined force. When the packaging boxes 1 are stacked, the alignment block 11 is nested with the surface of another packaging box 1, and the anti-compression device 12 aligns with the lower base 121 inside the other packaging box 1. The rod top block 128 is placed on the lower surface of the lower base 121 inside the other packaging box 1. While under force, the rod top block 128 moves vertically downward with the assistance of the fixing block 126, compressing the compression spring 123, while the slider 124 slides between the side slide rails 125. The anti-deviation guard 122 prevents the compression spring 123 from deviating outward and supports the upper rod top block 128, thus supporting the other packaging box 1 synchronously with the packaging box 1, dispersing the force, improving the compressive energy supply, and preventing cracking at the contact points on the surface of the packaging box 1.

Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
