Description

Technical Field

[0001] This utility model relates to the field of spring buckle manufacturing technology, and in particular to a spring buckle. Background Technology

[0002] A sofa is a multi-seat chair with cushions, typically equipped with springs, foam, and armrests; it belongs to the category of upholstered furniture. Among them, spring sofa cushions are a popular choice for home furnishings due to their elastic support and breathability. They are also less prone to deformation even after prolonged use, making them popular with many consumers. During the production process of spring cushions, spring clips need to be fixed to the spring cushion frame, and then the two ends of the springs are hung on the clips. Existing spring clip structures, such as patent number "202221355654.2 A Sofa Spring Clip," have a fixing part 1 and a bending part 2. The opening angle is limited after these two parts are combined, meaning the opening angle is relatively small. This structure makes blind insertion difficult during installation and inconvenient when installing springs, requiring further improvement. Utility Model Content

[0017] The following detailed description, in conjunction with the accompanying drawings, will further illustrate this utility model. Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] It should be noted that when a component is said to be "mounted on" another component, it can be directly mounted on the other component or may be interspersed with a component. When a component is said to be "set on" another component, it can be directly set on the other component or may be interspersed with a component. When a component is said to be "fixed to" another component, it can be directly fixed to the other component or may be interspersed with a component.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0021] like Figures 1 to 4 As shown, a spring buckle of this utility model includes a main body 1, a foot nail 2, a first bent portion 3, a connecting portion 4, and a second bent portion 5. The foot nail 2 is disposed on one side of the main body 1, and the other side of the foot nail 2 is inserted and fixed to a spring pad frame. One end of the first bent portion 3 is connected to the main body 1, and the other end is connected to the connecting portion 4. The second bent portion 5 is connected to the other end of the connecting portion 4, and the second bent portion 5 is bent outward. The main body 1, the first bent portion 3, the connecting portion 4, and the second bent portion 5 are connected in sequence to form an opening 6 that cooperates with the spring.

[0022] Because the second bend 5 bends outward, the angle of the opening 6 is increased, which is more conducive to the cooperation between the spring and the spring clip, enabling blind insertion. The opening 6 can reach close to 90 degrees, but in this embodiment it is 80 degrees.

[0023] To facilitate machine bending and reduce the force applied, a first hole 7 is provided at the junction of the second bending part 5 and the connecting part 4.

[0024] To further facilitate bending and reduce the force applied, there are two first holes 7. In this embodiment, the two first holes 7 correspond to two second protrusions 9, that is, the second protrusions 9 are formed by stamping the first holes 7 and are arranged side by side.

[0025] To reduce friction between the spring and the spring clip, that is, to reduce metal-to-metal friction and ensure service life, a gasket 10 is also included. The main body 1 and the second bending part 5 are respectively provided with a first protrusion 8 and a second protrusion 9. The gasket 10 is disposed at the first bending part 3, and the two ends of the gasket 10 respectively cooperate with the first protrusion 8 and the second protrusion 9, so that the gasket 10 is fixedly installed at the first bending part 3.

[0026] To make the gasket 10 more securely installed, there are two of each of the first protrusion 8 and the second protrusion 9.

[0027] For a more secure installation, the foot spikes 2 are set perpendicular to the main body 1, although a slight angular offset is acceptable.

[0028] The sofa and spring buckle are installed more securely and are not easy to pull out. The foot nail part 2 has four nails, two of which are equipped with barbs 201.

[0029] It is worth mentioning that, in order to facilitate bending the first bending portion 3, a second hole 11 is provided on the first bending portion 3. In this embodiment, the second hole 11 passes through the connecting portion 4, the first bending portion 3, and the main body portion 1.

[0030] Furthermore, in order to enhance the strength of the first bend 3, a first reinforcing rib 12 is provided at the outer edge of the second hole 11.

[0031] Furthermore, in order to enhance the strength of the first bend 3, second reinforcing ribs 13 are provided at the edges on both sides of the first bend 3.

[0032] It is worth mentioning that in this embodiment, the first bending portion 3 bends inward, and the second bending portion 5 bends outward. The main body portion 1 and the connecting portion 4 are planar.

[0033] In this embodiment, the foot spike 2, the first protrusion 8, and the second protrusion 9 are all formed by stamping. That is, except for the gasket 10, the rest are all one piece made of metal. Among them, the gasket 10 is made of plastic.

[0034] Furthermore, to ensure the strength of the first bend 3 and the opening angle of the second bend 5, and to facilitate compatibility with springs of different sizes, the radius of the rounded corner R1 at the first bend 3 is 4.5 ± 1.5 mm, preferably 4.5 mm in this embodiment; the radius of the rounded corner R2 at the second bend 5 is 3.2 ± 1.5 mm, preferably 3.2 mm in this embodiment. Also, to ensure strength, the thickness A of the main body 1, the foot nail 2, the first bend 3, the connecting part 4, and the second bend 5 is 0.9–1.2 mm, preferably 1 mm. Furthermore, the angle B formed by the connecting part 4 and the main body 1 is 14.5 ± 5 degrees, preferably 14.5 degrees.

[0035] When in use, the spring clip is fixed to the spring cushion frame of the sofa, and then the two ends of the spring are hung on the first bend 3 of the spring clip, which increases the angle of the opening 6, making it easier for the spring and the spring clip to cooperate, and enabling blind insertion.

[0036] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0037] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Any appropriate changes and variations made to the above embodiments within the scope of the essential spirit of the present utility model shall fall within the scope of protection claimed by the present utility model.
