Description

Technical Field

[0001] The utility model relates to the technical field of buckles, in particular to an elastic buckle for convenient disassembly and fixing of a stud. Background Technique

[0002] When assembling the automobile front bulkhead sound insulation and heat insulation pad, the connection and fixing method of the stud and the metal reed is usually used. However, this fixing method is a one-way snap-fit assembly and is not easy to disassemble and repair. Therefore, an elastic buckle for convenient disassembly and fixing of the stud is designed to facilitate disassembly and assembly. Content of the Utility Model

[0003] The utility model aims to solve the above technical problems and provides an elastic buckle for convenient disassembly and fixing of a stud.

[0004] To solve the above technical problems, the technical solution provided by the utility model is as follows:

[0005] An elastic buckle for convenient disassembly and fixing of a stud, including a buckle base, a clamping post housing is installed on the buckle base, a movable connecting plate is relatively installed in the clamping post housing, a guiding plate is installed on the connecting plate, an extrusion groove is opened on the outer side of the upper end of the clamping post housing, two flipable pressing plates are installed on both sides of the guiding plate, an expansion plate is installed at the lower end of the pressing plate and one end of the expansion plate is connected to the inner wall of the extrusion groove, and a clamping tongue for clamping the stud is installed on the connecting plate.

[0006] Preferably, a pressing plate flipping groove is opened at the upper end between the guiding plate and the pressing plate, and when the pressing plate flips downward, the expansion plate is driven to abut against one side of the extrusion groove, thereby driving the guiding plate to move upward.

[0007] Preferably, fixing rings are installed at the lower ends of the two connecting plates, and the clamping tongue is installed on the fixing rings.

[0008] Preferably, a U-shaped movable groove is opened on the outer side of the clamping post housing so that a movable protrusion is formed on the clamping post housing.

[0009] Preferably, the lower end of the movable protrusion is connected to the upper end of the clamping tongue.

[0010] Preferably, an installation groove for mating with the stud installation is opened on the buckle base.

[0011] After adopting the above structure, the utility model has the following advantages:

[0012] The utility model pinches the pressure plates on both sides to flip downward, and the expansion plates touch the lever fulcrums of the extrusion groove respectively. The pressure plates continue to apply pressure and flip, and the expansion plates contact and deform the housing of the clamping column. The internal clamping tongue in the vertical direction is forced to tilt outward. At this time, the buckle can be separated from the stud, completing the convenient disassembly and assembly of the reusable stud. It is easier to disassemble and assemble than the traditional one-way irreversible spring clip and has reuse value.

[0013] The above summary is for the purpose of description only and is not intended to be limiting in any way.

[0022] Embodiments of the present application will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present application and should not be construed as a limitation of the present application.

[0023] In the description of the present application, it should be noted that, unless otherwise clearly specified and defined, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and can be the communication inside two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to specific circumstances.

[0024] The following further describes the present utility model in detail in combination with the full text.

[0025] Combined with the attached Figures 1-6 , an elastic buckle for convenient disassembly and fixation of a stud, including a buckle base 5, a clamping post housing 7 is installed on the buckle base 5, a movable connecting plate 8 is relatively installed inside the clamping post housing 7, a guide plate 9 is installed on the connecting plate 8, an extrusion groove 4 is opened on the outer side of the upper end of the clamping post housing 7, flipable pressing plates 2 are installed on both sides of the guide plate 9, an expansion plate 3 is installed at the lower end of the pressing plate 2 and one end of the expansion plate 3 is connected to the inner wall of the extrusion groove 4. Specifically, the expansion plate 3 is a pressing plate expansion structure for assisting the pressing plate 2 to apply force to the clamping post housing 7, and a clamping tongue 6 for clamping the stud is installed on the connecting plate 8. When the present utility model is specifically implemented, the elastic buckle is an integrally formed structure, and the elastic buckle is made of elastic plastic or an elastic material.

[0026] A pressing plate flipping groove 1 is opened between the upper ends of the guide plate 9 and the pressing plate 2. When the pressing plate 2 flips downward, it drives the expansion plate 3 to abut against one side of the extrusion groove 4, thereby driving the guide plate 9 to move upward. Specifically, the thinning of the pressing plate flipping groove 1 is beneficial for the pressing plate 2 to flip downward, and the boss of the extrusion groove 4 is a lever fulcrum for supporting the structure of the pressing plate 2.

[0027] Fixed rings 11 are installed at the lower ends of the two connecting plates 8, and the clamping tongue 6 is installed on the fixed rings 11.

[0028] A U-shaped movable groove 10 is opened on the outer side of the clamping post housing 7, so that a movable protrusion 12 is formed on the clamping post housing 7. The lower end of the movable protrusion 12 is connected to the upper end of the clamping tongue 6. The clamping tongue 6 is clamped with the stud to complete the fixation. When an upward force is applied, the clamping tongue 6 and the movable protrusion 12 can only exert force outward (the outer side of the stud) and tilt upward. At this time, separating the clamping tongue 6 of the buckle from the stud can complete the disassembly.

[0029] The buckle base 5 is provided with an installation groove for fitting the stud, and the buckle base 5 presses the soft decoration. Figure 5 and Figure 6 As shown, the stud is inserted into the clamping column housing 7 through the installation groove, and the stud is clamped by the clamping tongue 6.

[0030] The working principle of this utility model:

[0031] After the buckle and stud are assembled, Figure 5 and Figure 6 As shown in the cross-sectional view during installation, pinch the pressure plates 2 on both sides by hand and flip them downward, and the expansion plates 3 touch the lever fulcrums of the extrusion groove 4 respectively. When the pressure plates 2 continue to be pressed and flipped, the expansion plates 3 come into contact with the clamping column shell 7 and deform it, driving the guide plate 9 upward, and the connecting plate 8 moves in the clamping column shell 7. The internal clamping tongue 6 in the vertical direction is forced to tilt outward, and the buckle can be separated from the stud.

[0032] The above describes the utility model and its implementation methods, which is not restrictive. What is shown in the full text is only one of the implementation methods of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it, without departing from the purpose of the invention of the utility model, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the utility model.
