Description

Technical Field

[0001] The invention relates to the technical field of packaging boxes, and in particular provides a modular packaging box made of diatom boards. Background Art

[0002] With the development of modern logistics, the amount of packaging boxes is increasing. At present, there are many kinds of express boxes on the market. Common express box carton materials include corrugated paper, honeycomb paperboard, pulp molding and cushioning kraft paper pads. Cartons have the characteristics of strong flexibility, but they are prone to tearing, flattening, and the strength is greatly reduced after contact with water, which makes them more prone to damage. The wear rate of carton is high and cannot be repaired, the recycling rate is low, and the pollution is large. Plastic box materials are not easy to be flattened, but they often have cracking and damage, which cannot be repaired, the recycling rate is low, and the pollution is serious. Diatom board has good hygroscopicity and can effectively adjust the humidity of the environment. The diatom board itself has certain antibacterial properties, which helps to maintain the hygiene inside the packaging box and reduce the moisture or mildew of items caused by humidity changes. At the same time, it is light in weight and has good firmness. It is generally used for the transportation of high-value goods such as medicines with high requirements for humidity and mold or electronic products with high environmental requirements.

[0003] The existing packaging boxes made of diatom boards have a simple connection and fixing method and lack a consistent box support structure. At the same time, since the diatom boards are relatively brittle, they are easily damaged by squeezing or impact, resulting in a lack of strength in the entire box structure.

[0043] For example, in one embodiment: the outer end of the linkage slide plate 322 is made of elastic material.

[0044] For example, in one embodiment: when the packaging box needs to be assembled, the two side panels 25 are respectively installed in the lateral mounting frame 111 away from the middle mounting frame 12, the outer ends of the four connecting columns 112 are clamped and installed at the four corners on the inner side of the lateral mounting frame 111 away from the middle mounting frame 12, and the two ends of the two end side panels 23 are respectively inserted and installed in the side panel mounting grooves 117 on the inner sides of the four connecting columns 112, and the positioning clamping blocks 26 on the end side panels 23 are clamped in the side panel clamping grooves 118, until the side walls of the end side panels 23 are inserted and installed in the panel clamping grooves 113 of the lateral mounting frame 111 away from the middle mounting frame 12, so as to complete the installation of the end side panels 23. Subsequently, the two docking panels 24 are installed again according to the above steps, and the preset card slot 115 is arranged opposite to the preset installation slot 121, and then the inner end of the connecting column 112 is carded in the other lateral installation frame 111, and the inner sides of the two end lateral panels 23 and the inner sides of the two docking panels 24 are carded in the panel card slot 113 of the other lateral installation frame 111. Then, the four rubber corner mounting blocks 132 are fixedly installed at the corners of the lateral mounting frame 111 away from the middle mounting frame 12, and then the sliding block 131 is entered into the docking slot 119 along the transverse slot 116 using the sliding card column 133, and the outer end of the outer wall of the sliding block 131 enters the preset through slot 134, and then the sliding block 131 is continued to be pushed. Since the inner diameter of the preset through slot 134 gradually decreases from the inside to the outside, when the sliding block 131 is continued to be pushed, the outer end of the sliding block 131 will be stuck in the rubber corner mounting block 132. At this time, one of the sliding card columns 133 will be located in the docking slot 119, and the other sliding card column 133 will be located in the transverse slot 116, thereby completing the installation of the opposite side mounting frame 11. Then, the two end panels 21 are respectively installed on the top and bottom of the middle installation frame 12, and the two main panels 22 are respectively installed on the two ends of the middle installation frame 12, and the positioning card blocks 26 of the two main panels 22 and the positioning card blocks 26 of the two end panels 21 are clamped in the clamping grooves of the inner wall of the middle installation frame 12, thereby completing the installation of the middle installation frame 12 and the two end panels 21 and the two main panels 22. Then, the docking card blocks 114 on the two side installation frames 11 are clamped and installed in the docking card grooves 123 on both sides of the middle installation frame 12, and are clamped and installed in the four clamping assemblies 30 using four locking components 40. Then, the installation of the packaging box is completed, and the installed packaging box is unified in form, quick to disassemble and assemble, and firmly limited. The corners of the packaging box that are easily subjected to stress during transportation are reinforced using the side installation frame 11. In addition, each panel component is easy to disassemble. When a panel is damaged, the panel can be directly replaced, which is convenient and easy, greatly reducing the transportation cost.

[0045] For example, in one embodiment: when it is necessary to clamp the locking assembly 30 in the locking assembly 40, pull the locking rotating plate 431 to rotate upward around the locking seat 42, and make the side wall of the locking mounting plate 41 abut against the side wall of the locking mounting seat 31, and then lower the locking rotating plate 431, so that the locking rotating plate 431 rotates downward under the action of the compression spring 44, so that the lock 432 is clamped in the locking groove 313. When the lock buckle 432 is locked in the lock buckle groove 313, the lock trigger slider 321 will move downward along the linkage slide groove. Since the inclined surface 328 abuts against the abutting surface 327, the linkage slide plate 322 will slide outward along the horizontal installation slide 315 until the linkage locking block 323 is arranged opposite to the limiting concave block 411, and the linkage locking block 323 moves upward along the vertical slide groove 329 under the action of the linkage spring 333, so that the top surface of the linkage locking block 323 abuts against the bottom surface of the limiting concave block 411, and the linkage locking column 334 on the linkage locking block 323 passes through the linkage sliding hole 412 and the interlocking hole 445 and abuts against the outer wall of the return ball 434. Then the lock buckle 432 is locked and locked to prevent the lock buckle 432 from loosening due to vibration during subsequent transportation.
