Description

Technical Field

[0001] This utility model belongs to the field of packaging carton connection technology, specifically relating to a carton connecting buckle. Background Technology

[0002] With the development of the times, online shopping has entered thousands of households. Many people buy cardboard boxes online to use as storage boxes and moving boxes. Before use, cardboard boxes are laid flat. Large cardboard boxes have a larger area after being laid flat, which is inconvenient for express delivery. When packing and shipping, the flat cardboard boxes need to be folded in half, which results in the cardboard boxes that buyers receive being folded. Although they can still be used, they are not aesthetically pleasing and greatly affect the buyer's shopping experience. Traditional carton assembly processes, including gluing or stapling, must be completed before the carton leaves the factory and cannot be changed. The large surface area of ​​large, flat cartons also presents challenges for courier handling and shipping. To address these issues, this applicant proposes a carton connector buckle that can replace gluing and stapling for carton assembly. At the factory, connecting holes are simply die-cut at the carton's flaps and side joints, eliminating the need for gluing and stapling. During packing and shipping, the carton is folded inwards along the crease lines, preserving its integrity while reducing the flat surface area and increasing stacking thickness, thus facilitating courier transport. Buyers receive cartons without unsightly creases. To complete the assembly, simply attach the matching carton connector buckle through the connecting holes from both the inside and outside of the carton and tighten it. The process is simple, significantly improving the buyer's shopping experience and the overall usability of the carton. Utility Model Content

[0003] The purpose of this utility model can be achieved through the following technical solution: a carton connecting buckle, including a male buckle 1 and a female buckle 2. The male buckle 1 is composed of a male buckle base plate 101 and a male buckle post 102, and the female buckle 2 is composed of a female buckle base plate 201 and a female buckle post 202. In use, the female buckle post 202 is passed through the overlapping tongue connection hole 302 and the box side connection hole 304 of the carton 3, and then the male buckle post 102 is inserted into the female buckle post 202 from the other side of the carton and pressed tightly. The two will interlock and snap together. The male buckle base plate 101 and the female buckle base plate 201 form a clamp that tightly adheres to the box board from both the inside and outside of the carton and clamps and fixes the carton tongue 301 and the box side connection part 303 to complete the connection into a carton, achieving the same carton-forming effect as gluing or nailing.

[0004] Furthermore, the base plate of the carton connecting buckle (including male buckle base plate 101 and female buckle base plate 201) is elliptical, with a maximum length of 80 mm, a maximum width of 40 mm, and a thickness of 3 mm. One side of the base plate is flat, and the other side is perpendicularly connected to the tail of the buckle post. One base plate can have one or more buckle posts, and the number of buckle posts for the matching male and female buckles is the same. The flatness of the base plate is larger than the diameter of the buckle post. The following description uses a double buckle post as an example. It should be noted that the length, width, and height data mentioned are only for ease of description and should be adjusted according to specific circumstances in actual application.

[0005] Furthermore, the individual male buckle post is 10 mm high and consists of four identical frustum-shaped segments connected in the same direction, forming a cylinder with protrusions. The largest diameter of the frustum is 10 mm and the smallest is 6 mm. Between the segments, there is a stepped, 2 mm protrusion. The post is thicker at the tail and thinner at the head. The entire male buckle post is divided into four parts by two V-shaped grooves that intersect in a cross shape. The grooves run through the entire post, with the grooves wider at the head and narrower at the tail. The grooves cause the post to contract towards the center when under force, making it easy to pass through the smallest diameter part of the female buckle post cavity. After the force is released, the post will automatically spring back to its original diameter and lock with the female buckle post. The female buckle post is 10 mm high and has an outer diameter of 16 mm. It is an open, hollow cylinder with an internal hollow cavity shape corresponding to the shape and size of the male buckle post. It consists of four hollow frustum-shaped segments, resembling a funnel. Once the male buckle post is inserted, it is locked in place and cannot be pulled out.

[0006] Furthermore, the carton connecting buckle needs to have connecting holes die-cut at corresponding positions on the carton 3 for proper use. Specifically, a connecting hole 302 is die-cut on the carton tongue 301, and a side connecting hole 304 is die-cut on the side connecting portion 303. When using the carton connecting buckle, first connect the carton tongue 301 and the side connecting portion 303 together, with the carton tongue 301 inside and the side connecting portion 303 outside, so that the connecting hole 302 aligns with the side connecting hole 304. 04. Overlapping: At this point, the female buckle post 202 is passed through the overlapping connection hole from inside the carton, and the male buckle post 102 is inserted into the female buckle post 202 from the outside of the carton. The male buckle base plate 101 and the female buckle base plate 201 are simultaneously tapped from both inside and outside to make the male buckle post 102 insert into the female buckle post 202. At the same time, the male buckle base plate 101 and the female buckle base plate 201 are tightly attached to both sides of the carton board to form a clamp to clamp and fix the carton tongue 301 and the carton side connection part 303, thus completing the carton assembly.
