Description

Technical Field

[0001] The present application relates to the technical field of elastic buckles, and specifically discloses a structure for preventing an elastic buckle from rotating and falling off. Background Art

[0002] At present, there are many buckle structures used in automobiles, with complicated shapes and types, and corresponding matching structures and limiting methods. Most buckle structures are elastic buckles;

[0003] Elastic buckle: including elastic parts and connecting parts, the principle is basically the same. The elastic part has a variable size. The elastic part is inserted into the limit hole through a small size, and then the elastic part changes from a small size to a large size, thereby realizing the connection of the elastic buckle. The connecting part is used to connect the objects installed on the elastic buckle;

[0004] This type of elastic buckle is frequently used, but it also has certain problems: although the elastic part can control the freedom of up and down movement, it cannot control the freedom of left and right rotation. Since the rotation of the entire elastic buckle cannot be restricted, there is a risk of loose assembly based on the rotation;

[0005] Later, with the improvement of technology, a limiting structure was added to the connecting piece to restrict the rotation of the elastic buckle. This elastic buckle also has certain problems. That is, if it is forcibly rotated and squeezed, the spring piece will be deformed under the force, which may cause the spring piece to break and the assembly to loosen. There is also a risk of the buckle failing and falling off. In view of this, the inventor proposed a structure to prevent the elastic buckle from rotating and falling off. Utility Model Content

[0006] The utility model aims to solve the problem that the traditional elastic buckle has insufficient structure to limit the degree of freedom, thus causing the elastic buckle to fall off.

[0007] In order to achieve the above object, the utility model provides the following basic solutions:

[0008] A structure for preventing an elastic buckle from rotating and falling off, comprising a limiting rib fixedly connected to the periphery of a limiting hole for limiting an elastic member and a limiting assembly fixedly connected to the bottom of the elastic member and clamped to the limiting hole;

[0009] The limiting assembly includes a vertical block, an elastic curvature plate symmetrically fixed on both sides of the vertical block, and a notch surface opened at the end of the elastic curvature plate, the notch surface is clamped with the inner wall of the limiting hole, a plurality of grooves are opened on the notch surface, a rotating wheel whose rotation direction is consistent with the expansion direction of the elastic curvature plate is installed in the groove, and the rotating surface of the rotating wheel is in contact with the bottom of the limiting hole.

[0010] The principles and effects of this basic solution are:

[0011] 1. Compared with the prior art, the device has a simple structure and an ingenious design. The device is provided with a limiting rib, which can effectively block the rotation of the device and prevent the buckle from rotating.

[0012] 2. Compared with the prior art, this device is provided with a limit assembly to prevent the device from falling off and shifting.

[0013] 3. Compared with the prior art, a plurality of grooves are provided on the notch surface, and a rotating wheel whose rotation direction is consistent with the unfolding direction of the elastic arc plate is installed in the groove. The rotating surface of the rotating wheel contacts the bottom of the limiting hole. The notch surface can accelerate the clamping of the device and limit the rotation direction of the rotating wheel. When rotation occurs, the rotating wheel can block the rotation and avoid the rotation of the device.

[0014] 4. Compared with the prior art, this device has better stability and more fixing freedom than a single buckle limit matching surface. At the same time, the buckle limit hole is suitable for more types of installation buckles, and the installation is simple. The strength stability and locking effect are maintained longer, and it can better prevent the buckle from unhooking, and the installation can be more stable.

[0015] Furthermore, the limiting rib is a frame-type limiting rib, and the center of the frame-type limiting rib is consistent with the center of the limiting hole.

[0016] Furthermore, a gap is left between the frame-shaped limiting rib and the elastic member, and the gap is less than 0.5 mm.

[0017] Furthermore, a blocking block is fixedly connected to the inner side of the notch surface, and the blocking block contacts the inner wall of the limiting hole. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0025] The reference numerals in the drawings of the specification include: elastic member 1, limiting hole 2, limiting plate 3, limiting surface 4, limiting rib 5, vertical block 6, elastic arc plate 7, buckle body 8, notch surface 9, groove 10, rotating wheel 11.

[0026] Implementation example Figure 1 and Figure 2 As shown:

[0027] like Figure 1 As shown, Figure 1 This is the first generation of products. The first generation of elastic buckles can only limit the up and down directions, and there is no limit on the freedom of left and right rotation. Therefore, there is a risk of the elastic buckle falling off when rotating;

[0028] Similarly, if Figure 2 As shown, Figure 2 The second generation product has an additional set of limit plates 3 in the elastic buckle, which further limits the degree of freedom of rotation. The problem is that since the two ends of the elastic buckle are made of spring material, the spring is deformed by force when it is rotated and squeezed, which may cause the spring to break and the assembly to loosen. There is also the risk of the buckle failing and falling off. Based on the above product defects, a set of Figure 3 and Figure 4 and Figure 5 , a newer and more restrictive structure for preventing the elastic buckle from rotating and falling off.

[0029] A structure for preventing an elastic buckle from rotating and falling off comprises a limiting rib 5 fixed around a limiting hole 2 for limiting an elastic member 1 and a limiting assembly fixed to the bottom of the elastic member 1 and engaged with the limiting hole 2, wherein the limiting rib 5 is installed on a limiting surface 4.

[0030] The limiting assembly includes a vertical block 6, an elastic radian plate 7 symmetrically fixed on both sides of the vertical block 6, and a notch surface 9 opened at the end of the elastic radian plate 7, the notch surface 9 is clamped with the inner wall of the limiting hole 2, and a plurality of grooves 10 are opened on the notch surface 9. A rotating wheel 11 whose rotation direction is consistent with the expansion direction of the elastic radian plate 7 is installed in the groove 10, and the rotating surface of the rotating wheel 11 contacts the bottom of the limiting hole 2. The limiting rib 5 is a frame-type limiting rib 5, and the center of the frame-type limiting rib 5 is consistent with the center of the limiting hole 2. A gap is left between the frame-type limiting rib 5 and the elastic member 1, and the gap is less than 0.5mm. A blocking block is fixed to the inner side of the notch surface 9, and the blocking block contacts the inner wall of the limiting hole 2. A buckle body 8 is installed on the top of the elastic member 1, and the buckle body 8 is used to connect external parts.

[0031] Specific implementation process:

[0032] The first step is to move the elastic radian plate 7 toward the limiting hole 2 and insert it into the limiting hole 2. After the elastic radian plate 7 is inserted into the limiting hole 2, the elastic radian plate 7 is reset, and the two sides of the elastic radian plate 7 are larger than the aperture of the limiting hole 2 to achieve snap connection;

[0033] In the second step, due to the limitation of the limiting rib 5, the elastic part 1 cannot rotate. At this time, the rotating wheel 11 on the notch surface 9 accelerates the clamping of the elastic arc plate 7, and the rotation direction of the rotating wheel 11 is consistent with the elastic arc plate 7. Therefore, even if an external force acts on the elastic part 1 and wants the elastic part 1 to rotate, the rotating wheel 11 can cooperate with the use of the limiting rib 5 to prevent the elastic part 1 from rotating.

[0034] The device solves the problem that the traditional elastic buckle has insufficient structure to limit the degree of freedom, which leads to the elastic buckle falling off.

[0035] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
