Description

Technical Field

[0001] This utility model relates to the field of packaging material processing technology, and in particular to a waterproof structure for printed packaging boxes. Background Technology

[0002] Waterproof printing and packaging box structures utilize a purely physical method to achieve waterproofing, aiming to prevent damage to products from moisture and other environmental factors. This technology employs the selection of packaging materials with moisture-proof, damp-proof, and waterproof properties, combined with a rational packaging structure design and effective moisture-proof measures, ensuring that products remain dry and stable during transportation, storage, and use. It is widely used in various fields such as food, pharmaceuticals, and electronics. In the food industry, this technology ensures the dryness and taste of food, extending its shelf life; in the pharmaceutical industry, it protects medicines from the destructive effects of humid environments, ensuring their efficacy and safety; and in the electronics industry, it prevents malfunctions and damage caused by moisture.

[0003] Existing packaging boxes generally have poor waterproofing and low overall strength, which can lead to valuable items inside getting wet and damaged during transportation, causing unnecessary economic losses. In addition, poor structural strength can cause items to be squeezed and dropped, resulting in unnecessary economic losses. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a waterproof structure for printed packaging boxes, aiming to improve the problems of poor waterproof sealing and fragile overall structure of the packaging boxes.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a waterproof structure for a printed packaging box, comprising a box body, a guide strip fixedly connected to the inner wall of the box body, a nylon plate slidably connected to the outer wall of the guide strip, a connecting block fixedly connected to the lower surface of the nylon plate, a key pin fixedly connected to the outer wall of the connecting block, and a self-locking component provided on the inner wall of the box body.

[0006] The self-locking assembly includes a base plate, a grooved plate fixedly connected to the outer wall of the base plate, a pin slidably connected to the inner wall of the grooved plate, a first clamping ring slidably connected to the outer wall of the pin, a second clamping ring slidably connected to the outer wall of the pin, a key pin slidably connected to the inner wall of the first clamping ring, and a key pin slidably connected to the inner wall of the second clamping ring. A spring is fixedly connected to the outer walls of both the first and second clamping rings, with one end of the spring fixedly connected to the outer wall of the base plate.

[0007] Furthermore, a back panel is fixedly connected to the lower surface of the box, and an inner packaging panel is rotatably connected to the back panel via a hinge, and an outer packaging panel is rotatably connected to the back panel via a hinge.

[0008] Furthermore, a retaining ball is fixedly connected to the outer wall of the inner packaging board, a hinge is provided on the inner wall of the inner packaging board, and a magnetic suction plate is provided at one end of the inner packaging board.

[0009] Furthermore, the inner wall of the outer packaging panel is provided with a hinge, the outer wall of the outer packaging panel is provided with a buckle hole, and a buckle shell is fixedly connected to the outer wall of the outer packaging panel.

[0010] Furthermore, a bushing is fixedly connected to the upper surface of the nylon plate, a rubber strip is fixedly connected to the lower surface of the nylon plate, and a handle is rotatably connected to the inner wall of the bushing.

[0011] Furthermore, a top plate is fixedly connected to one side of the outer wall of the box, and a base is fixedly connected to the other side of the outer wall of the box.

[0012] Furthermore, the outer wall of the top plate is fixedly connected to the upper surface of the back plate, and the outer wall of the base is fixedly connected to the upper surface of the back plate.

[0013] Furthermore, a crossbeam is fixedly connected to the inner wall of the box, and a vertical rod is fixedly connected to the inner wall of the box.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the sliding door self-locking component uses a locking tongue under the sliding nylon waterproof board that engages with a spring clamp to complete the self-locking process. The nylon board has a waterproof rubber strip at the end to increase the internal waterproof sealing. The opening and closing of the self-locking component is made more convenient by placing the handle and guide strip flat on the nylon board. The nylon board, guide strip and rubber strip work together to provide better physical sealing and waterproof performance. The internal structure is also equipped with columns and crossbars to reinforce the overall structure and make the structure more stable.

[0016] 2. In this utility model, the double-layer packaging board adopts an inner and outer two-layer packaging board design. The inner packaging board is closely attached to the inside of the box body and is magnetically attached to the outer wall of the box body, which can firmly wrap the box body and bring good sealing performance. The outer packaging board has a snap hole at the end, which, together with the ball buckle on the outer wall of the inner packaging board, realizes physical opening and closing. After closing, it will firmly stick to the inner packaging board, which not only further enhances the overall sealing performance, but also further strengthens the structure.
