Technical Field

[0001] The utility model relates to the technical field of hardware fittings, in particular to a quick disassembly and assembly type connection structure. Background Technique

[0002] Quick-release fittings refer to those fittings that can be quickly installed and disassembled. The design purpose of quick-release fittings is to improve work efficiency, simplify the assembly and disassembly process, reduce the use of tools, and lower maintenance costs.

[0003] Advantages of quick-release fittings:

[0004] High efficiency and convenience: It can significantly reduce the assembly and disassembly time and improve work efficiency;

[0005] Simple operation: Usually no professional tools are required, and users can easily complete the operation;

[0006] Strong versatility: Many quick-release fittings have standardized interfaces and are applicable to a variety of devices and application scenarios;

[0007] High safety: Safety factors are considered in the design to avoid equipment damage or personal injury caused by improper operation.

[0008] At present, for some sofas or chairs made of metal materials, the hip cushions and the overall frames are mainly fixed by welding or screws. This results in a large space occupation during batch transportation. Therefore, it is necessary to improve the connection part and design a quick insertion structure for the hip cushions and the frames to facilitate split transportation or assembly use. Content of the Utility Model

[0009] The purpose of the utility model is to solve the above-mentioned disadvantages in the prior art and propose a quick disassembly and assembly type connection structure.

[0010] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0011] Design a quick disassembly and assembly type connection structure, including a quick-release pin head and a quick-release pin seat. The quick-release pin head and the quick-release pin seat are slidably arranged relative to each other. The cross-section of the slideway of the quick-release pin seat is a convex-shaped structure. The quick-release pin head fits and slides closely with the slideway. An installation plate is welded and fixed to the end of the quick-release pin head.

[0012] Specifically, the quick-release pin head, the quick-release pin seat and the installation plate are all made of stainless steel materials.

[0013] Specifically, the shape of the vertically opened front of the slideway of the quick-release pin seat is a conical structure.

[0014] Specifically, the position where the end of the quick-release pin head fits the vertically opened slideway is a conical structure.

[0015] The design scheme proposed by the present utility model has the following beneficial effects during application:

[0016] 1. By sliding the quick-release pin head and the quick-release pin seat, quick splicing of the two can be achieved. When applied at the connection position, stable installation can be ensured while also enabling quick disassembly. Compared with screw or welding installation methods, it has better flexibility. When transporting the object to which the quick-release structure is attached, it can be transported separately, reducing the occupied space. BRIEF DESCRIPTION OF THE DRAWINGS
