Detailed Description

Specific embodiments of the present utility model are described in further detail below. It should be understood that the description herein of the embodiments of the utility model is not intended to limit the scope of the utility model.

Fig. 1 to 2 are schematic structural views of a buckle capable of adapting to multiple size apertures according to the present utility model. The snap-fit multi-dimensional aperture comprises a base portion 10, a plug portion 20 provided on one side of the base portion 10, and a connecting portion 30 provided on the other side of the base portion 10, and further functional modules, such as chamfers provided on the side of the base portion 10, which are well known to those skilled in the art, and will not be described in detail herein.

The base 10 includes a base plate 11, and two receiving grooves 12 spaced apart from each other at the top of the base plate 11. In this embodiment, the top surface of the substrate 11 is rectangular, so that the processing and production of the bottom plate are facilitated. The receiving groove 12 is disposed corresponding to the insertion portion 20, and the specific position thereof will be described in detail below.

The clamping portion 20 includes a main rod 21 and two elastic pieces 22 symmetrically disposed at two sides of the end of the main rod 21. The main lever 21 is provided at a central position of one side of the base plate 11, thereby facilitating alignment of the engaging portion 20 by aligning the base plate 11 when in use by a user. In this embodiment, the main lever 21 is a cube column, thereby facilitating the installation of the elastic piece 22. The elastic pieces 22 are respectively arranged at the tops of two opposite side surfaces of the upright post 21, and are in an integral structure with the upright post 21. Each of the elastic pieces 22 includes a guide portion 221 having one end connected to the end of the main lever 21, and an abutment portion 222 provided at the end of the guide portion 221. The guide 221 forms an angle with the main lever 21. The included angle is acute so that one end of the two elastic pieces 22 forms a tip for easy insertion into the insertion hole. The connection part between the guide part 221 and the main rod 21 is in a convergent shape, so that when the elastic piece 22 bears an external force, the connection part between the guide part 221 and the main rod 21 is easier to bend and deform, the included angle between the guide part 221 and the main rod 21 is reduced, and the elastic piece 22 is convenient to insert into an insertion hole. An included angle is formed between the abutment portion 222 and the guiding portion 221, so that the end of the abutment portion 222 is inclined toward the main rod 21 to form an included angle with the main rod 21, and when the aperture sizes of the jacks are different, the edges of the jacks can abut against different positions of the outer wall of the abutment portion 222, so that enough pressure can be obtained. It should be noted that, the included angle between the extending direction of the abutment portion 222 and the extending direction of the main rod 21 is an obtuse angle, so as to ensure that the outer wall of the abutment portion 222 can be abutted by the hole edge of the jack. The outer side surface of the propping part 222 is horizontally provided with at least one guide groove 223, and the hole edge of the jack is clamped in the corresponding guide groove 223, so that the propping part 222 is prevented from generating offset in the propping process to influence the clamping effect.

The connection portion is used for fixing the base portion on the surface of the device. In this embodiment, the connection portion is a mushroom-shaped buckle.

When in use, if the object A and the object B are required to be fixed, a through jack is formed on the surface of the object B. The base is first mounted on the surface of the object a by the connection and the boom is extended perpendicularly to the surface of the object a. And then moving the object A and the object B so that the clamping part stretches into the jack. The guide part is continuously pressed in the moving process, so as to be close to the main rod 21, and further drive the abutting part to be also close to the main rod 21 until the connecting part of the guide part and the abutting part passes through the jack. And then continuously moving the object B, so that the hole edge of the jack is just clamped on the outer wall of the propping part. At this time, if opposite forces are applied to the object a and the object B, respectively, to separate them, the abutment portion will rotate about the base of the abutment portion under the force to prevent the abutment portion from coming out of the insertion hole. It should be noted that the aperture size of the adapted jack is related to the length of the abutment portion and the angle between the abutment portion and the main lever.

The above is only a preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model, and any modifications, equivalent substitutions or improvements within the spirit of the present utility model are intended to be covered by the claims of the present utility model.
