Description

Technical Field

[0001] This utility model relates to the field of cardboard box technology, specifically a high-strength cardboard box. Background Technology

[0002] Cardboard boxes are the most widely used packaging products. Depending on the materials used, there are corrugated cardboard boxes, single-layer cardboard boxes, etc., and they come in various specifications and models. Cardboard boxes commonly have three or five layers, while seven-layer boxes are less common. Each layer consists of linerboard, corrugated paper, core paper, and face paper. The linerboard and face paper are made of kraft paper or kraft paper, while the core paper is made of corrugated paper. Various items can be packed inside for storage, thus protecting and transporting the goods.

[0003] In existing technologies, when packaging bottle-shaped items with cardboard boxes, the bottles are prone to shaking and colliding, resulting in insufficient protection. Furthermore, the cardboard boxes are easily deformed by external forces, indicating inadequate strength. Therefore, we propose a high-strength cardboard box. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a high-strength cardboard box that solves the problems of bottle-shaped items easily shaking and colliding with each other, resulting in insufficient protection, and the cardboard box being easily deformed by external forces, thus lacking ideal strength.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A high-strength cardboard box includes a box body, a top cover at the top of the box body, a cushioning protection mechanism on the top cover and the bottom surface of the box body, and a reinforcing mechanism inside the box body;

[0007] The reinforcing mechanism includes two reinforcing frames, each with multiple connecting screw holes. Each reinforcing frame contains multiple sets of positioning rings.

A connecting block is fixedly connected between each set of positioning rings. A positioning rod is fixedly connected to each connecting block. A protective pad is fixedly connected to the inner wall of each positioning ring. Multiple limiting rods are provided between the multiple sets of positioning rings. Second bolts are provided at both ends of each limiting rod. Multiple fixing rods are provided between the two reinforcing frames. A first screw is fixedly connected to the bottom end of each fixing rod. A second screw is fixedly connected to the top end of each fixing rod. An adjusting nut is threaded onto the second screw. A connecting tube is fixedly connected to the top end of the adjusting nut. A third screw is rotatably connected to the top end of the connecting tube.

[0008] Preferably, the two reinforcing frames are matched with the inner cavity of the box, and the cross-sectional shape of the two reinforcing frames is set to rectangular, so that the reinforcing frames can be placed inside the box to reinforce the box and improve its strength and resistance to deformation.

[0009] Preferably, the multiple sets of positioning rings are detachably connected to the reinforcing frame by first bolts, and the multiple sets of limiting rods are detachably connected to the reinforcing frame by second bolts, so that the positioning rings and limiting rods can be disassembled and replaced.

[0010] Preferably, the limiting rod has multiple insertion holes, which match the positioning rod, allowing the positioning rod to be inserted into the insertion hole, thereby enabling the limiting rod to limit the positioning rings.

[0011] Preferably, both the first screw and the third screw are matched with connecting screw holes, which are located on opposite surfaces of the two reinforcing frames, so that the first screw and the third screw can be screwed into the connecting screw holes.

[0012] Preferably, the buffer protection mechanism includes a bubble pad, on which a first adhesive is fixedly connected, and a second adhesive is provided on the bottom surface and top cover of the box. The bubble pad is connected to the bottom surface and top cover of the box through the first and second adhesives, so as to play a buffer protection role.

[0013] This utility model provides a high-strength cardboard box. Compared with the prior art, it has the following advantages: This high-strength cardboard box can adapt to bottle-shaped items of different heights by changing the distance between the two reinforcing frames by rotating the connecting tube. Multiple sets of positioning rings are fixed to the reinforcing frames using a first bolt. Then, a limiting rod is fitted onto the positioning insert rod, and a second bolt is tightened to fix the limiting rod to the reinforcing frame. The bottle-shaped item is then placed inside the positioning ring. The positioning rings position the bottle-shaped item, preventing it from shaking and colliding with each other, thus improving the protective effect. The reinforcing frames strengthen the box body, increasing its strength and resistance to deformation. Attached Figure Description

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

[0020] Please see Figures 1 to 4 This utility model provides a technical solution:

[0021] A high-strength cardboard box includes a box body 1, a top cover 3 at the top of the box body 1, a buffer protection mechanism 4 on the top cover 3 and the bottom surface of the box body 1, and a reinforcing mechanism 2 inside the box body 1. The reinforcing mechanism 2 can strengthen the box body 1, improve its strength and resistance to deformation, and prevent bottle-shaped items from shaking and colliding with each other, thereby improving the protection effect.

[0022] The reinforcing mechanism 2 includes two reinforcing frames 201, each with multiple connecting screw holes 202. Inside each reinforcing frame 201 are multiple sets of positioning rings 203. Each positioning ring 203 has a fixing block 204 fixedly connected to both ends, and a first bolt 205 is provided on the fixing block 204. Each set of positioning rings 203 is fixedly connected to a connecting block 206, and a positioning rod 207 is fixedly connected to each connecting block 206. A protective pad 208, which is a rubber pad, is fixedly connected to the inner wall of each positioning ring 203 to protect bottle-shaped items. Multiple positioning rods 209 are provided between multiple sets of positioning rings 203. The positioning rods 209 can improve the stability of multiple sets of positioning rings 203. Each positioning rod 209 has a second bolt 210 at both ends. Multiple fixing rods 211 are provided between two reinforcing frames 201. Each fixing rod 211 has a first screw 212 fixedly connected to its bottom end and a second screw 213 fixedly connected to its top end. An adjusting nut 214 is threaded onto the second screw 213. A connecting tube 215 is fixedly connected to the top end of the adjusting nut 214. A third screw 216 is rotatably connected to the top end of the connecting tube 215.

[0023] Furthermore, the two reinforcing frames 201 are matched with the inner cavity of the box 1. The cross-sectional shape of the two reinforcing frames 201 is set to rectangular, so that the reinforcing frames 201 can be put into the box 1 to reinforce the box 1 and improve its strength and resistance to deformation.

[0024] Furthermore, multiple positioning rings 203 are detachably connected to the reinforcing frame 201 via first bolts 205, and multiple limiting rods 209 are detachably connected to the reinforcing frame 201 via second bolts 210, enabling the positioning rings 203 and limiting rods 209 to be disassembled, installed, and replaced.

[0025] Furthermore, the limiting rod 209 has multiple insertion holes that match the positioning rod 207, allowing the positioning rod 207 to be inserted into the insertion holes, thereby enabling the limiting rod 209 to limit the multiple sets of positioning rings 203.

[0026] Furthermore, both the first screw 212 and the third screw 216 are matched with the connecting screw hole 202, which is set on the opposite surface of the two reinforcing frames 201, so that the first screw 212 and the third screw 216 can be screwed into the connecting screw hole 202.

[0027] Furthermore, the cushioning protection mechanism 4 includes a bubble pad 401, on which a first adhesive 402 is fixedly connected. A second adhesive 403 is provided on the bottom surface of the box body 1 and the top cover 3. The bubble pad 401 is connected to the bottom surface of the box body 1 and the top cover 3 through the first adhesive 402 and the second adhesive 403. The bubble pad 401 protects the top and bottom of the bottle-shaped item, thus providing a cushioning protection function.

[0028] Working principle:

[0029] In use, rotating the connecting pipe 215 causes the adjusting nut 214 to rotate, which in turn moves the adjusting nut 214 along the second screw 213, adjusting the distance between the first screw 212 and the third screw 216. This changes the distance between the two reinforcing frames 201 to accommodate bottle-shaped items of different heights. Then, the first bolt 205 is used to fix multiple sets of positioning rings 203 onto the reinforcing frame 201. Next, the limiting rod 209 is fitted onto the positioning insert 207, and the second bolt 210 is tightened to fix the limiting rod 209 onto the reinforcing frame 201, thus providing a limiting and stabilizing effect for the positioning rings 203. Then, the bottle-shaped item is placed inside the positioning ring 203, which positions the bottle-shaped item to prevent it from shaking and colliding with each other, improving the protection effect. The reinforcing frame 201 strengthens the housing 1, increasing its strength and resistance to deformation.
