Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention.

Referring to fig. 1-5, a screwless buckle structure includes a front housing 1, a rear housing 3, and an intermediate fixing member disposed between the front housing 1 and the rear housing 3, wherein the front housing 1 is provided with at least one guide post 13, the guide post 13 is provided with a guide slot 15, a notch 17 is opened on a side wall of the guide post 13 corresponding to the guide slot 15, the intermediate fixing member is provided with a guide inclined plane 23 corresponding to the guide post 13, the guide inclined plane 23 is provided with at least one positioning hole 21 corresponding to the guide post 13, the positioning hole 21 allows the guide post 13 to pass through, the rear housing 3 is provided with a positioning post 31 capable of being sleeved in the guide slot 15, the positioning post 31 is provided with a guide rib 33 and a pressing rib 35, the pressing rib 35 is disposed on a lower half portion of the positioning post 31, the guide rib 33 is disposed on an upper half portion of the positioning post 31, and the guide rib 33 and the pressing rib 35 are connected in a seamless mode, and a clip 11 used for fixing the guide column 13 in the positioning hole is arranged on the outer side of the guide column 13. When guide post 13 got into in the locating hole 21, the condition of contradicting can take place for locating hole 21 and checkpost 11, consequently can make guide post 13 receive pressure to produce certain deformation, consequently the position of breach 17 returns and consequently diminishes for checkpost 11 passes through locating hole 21, and guide post 13 resumes, and breach 17 size resumes.
