Description

Technical Field

[0001] The utility model relates to the technical field of buckles, in particular to a building block buckle structure. Background Technique

[0002] The design of the pet building block box is similar to that of traditional building block toys and has the characteristics of being assembled and disassembled. This means that pet owners can freely combine and adjust the shape and structure of the box according to their own preferences and the needs of their pets. This flexibility not only increases the fun of the product but also makes the interaction between pet owners and their pets more interesting and rich.

[0003] The splicing of the pet building block box needs to be completed with the help of a buckle structure. The commonly used buckle for pet building block boxes is usually a "day"-shaped buckle. This buckle consists of a male head and a female head. When splicing, the male head needs to be inserted into the female head. The male head has a deformable protrusion, and this protrusion can be engaged with the corresponding slot in the female head. This kind of buckle is usually made of plastic. After being disassembled and assembled multiple times, the protrusion of the male head becomes smaller due to friction with the female head. Over time, the protrusion of the male head is prone to disengage from the slot of the female head, resulting in the failure of the engagement. For this reason, we propose a new buckle structure. An additional boosting rod is added to the male head, which can always push against the protrusion to ensure the stability of the engagement. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a building block buckle structure, which solves the problems raised in the above background technique.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0036] See also Figure 1-5 , the utility model provides a technical solution: a building block buckle structure, comprising a male head 1 and a female head 2 that buckle with each other;

[0037] The male connector 1 includes a handle 11, the bottom ends of which are connected to a guide rod 12, two symmetrically arranged elastic rods 13 and two symmetrically arranged booster rods 14, the guide rod 12 is located between the two booster rods 14, and the elastic rod 13 is located outside the booster rods 14. The handle 11, the guide rod 12, the elastic rod 13 and the booster rod 14 are a whole, which are formed by an injection molding process. During the injection molding, two through holes 17 are formed inside the handle 11 through a corresponding mold, and two through holes 17 are formed in the guide rod 12. A "V"-shaped deformation allowance groove 16 is formed between the insertion rod 12 and the auxiliary rod 14, and an unsealed opening is reserved in the through hole 17. The through hole 17 is connected to the deformation allowance groove 16 through the unsealed opening, and an oblong deformation allowance groove 2 18 is formed between the auxiliary rod 14 and the elastic rod 13. The bottom end of the auxiliary rod 14 is integrally connected to the protrusion 15, and the outer side of the elastic rod 13 is integrally connected to a step protrusion. When the male head 1 is inserted into the female head 2, the protrusion 15 will push the elastic rod 13 outward.

[0038] Please read Figure 6 As shown; a force unloading groove 25 is provided between the two outer sides of the handle 11 and the elastic rod 13, and a circular hole is provided between the elastic rod 13 and the force unloading groove 25. The circular hole is used to avoid cracking of the contact point. Because the edges of the circular holes are round, when the pressure is received during expansion, the arc will have a tightening effect, so the force will be better.

[0039] In addition, the female connector 2 includes a plug shell 21, which is also integrally formed through an injection molding process. A slot 22 adapted to the male connector 1 is provided inside the plug shell 21, and a clamping hole 23 connected to the slot 22 is provided on both sides of the slot 22. A clamping step 24 that can engage with the step protrusion of the elastic rod 13 is reserved at the top of the clamping hole 23.

[0040] When using this snap-fit ​​structure, the male connector 1 needs to be plugged into the inside of the female connector 2. During the plugging process, the step protrusion of the elastic rod 13 is squeezed inward by the plug shell 21, causing the elastic rod 13 and the auxiliary rod 14 to move inward, thereby reducing the space of the deformation margin groove 16. When the step protrusion of the elastic rod 13 enters the card hole 23, the elastic rod 13 will reset and rebound because it is no longer squeezed by the plug shell 21. At the same time, the auxiliary rod 14 will also rebound synchronously with the elastic rod 13, and the protrusion 15 of the auxiliary rod 14 will abut against the inner side of the elastic rod 13, that is, it can give the elastic rod 13 an outward thrust, so that the step protrusion of the elastic rod 13 can be tightly engaged with the card step 24 and is not easy to disengage.
