[0001] This utility model relates to the field of furniture technology, specifically to a seat bracket spring connection mechanism. Background Technology

[0002] Seating furniture is an essential type of furniture in people's daily lives, widely used in homes, offices, and various public spaces. To improve seating comfort, modern seating designs are constantly being optimized, especially in the base structure. Often, a combination of materials such as compression springs, plastic mesh, and foam layers is used. Through the proper coordination between these layers, pressure on the human body is effectively distributed, enhancing the seating experience.

[0003] However, in practical use, the serpentine spring connection structure commonly used in existing seating brackets still has some problems. For example, it is inconvenient to adjust, the connection is not secure, and the cushioning effect is poor. These problems can easily cause the seat to wobble during use, which not only affects comfort but also shortens the lifespan of the furniture. In addition, the position of most spring components is currently fixed, which cannot be flexibly adjusted according to different seating structures, thus limiting its application range.

[0004] Therefore, there is an urgent need for a more rationally structured seat bracket spring connection mechanism that can not only provide a stable and reliable connection, but also has good cushioning performance and convenient adjustment function, so as to comprehensively improve the stability, applicability and durability of the seat.

[0027] 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.

[0028] Please see Figure 1 An embodiment of this utility model provides a seat bracket spring connection mechanism, including: a frame 1 and a spring connector 2.

[0029] Among them, such as Figure 1 , Figure 4 and Figure 6 As shown, the frame 1 is a rectangular structure composed of no less than 4 splicing pipes 16 and no less than 4 corner connectors 4 connected to each other at their ends. The corner connectors 4 are located at the four corners of the frame 1, and both ends of each corner connector 4 are inserted into the interior of the splicing pipe 16 through the narrowing part 5.

[0030] In the embodiments of this application, a spring connector 2 is installed on the splicing pipe 16. The bottom of the spring connector 2 is also provided with a bending boss 12. The a-side of the spring connector 2 is an inclined surface or a vertical surface. Both sides of the spring connector 2 are integrally formed with triangular bosses 8. The insertion interface 10 is formed between the triangular bosses 8 and the bending bosses 12 to accommodate the serpentine spring 3.

[0031] According to the embodiments of this application, when using the spring connecting mechanism, the spring connector 2 is first slidably installed on the splicing pipe 16 of the frame 1. The number and position of the spring connector 2 can be flexibly adjusted according to the length of the splicing pipe 16 and the elasticity requirements of the seat. In addition, the bent boss 12 at the bottom of the spring connector 2, together with the triangular boss 8, can tightly abut against the inner wall of the splicing pipe 16, improving the stability of the spring connector 2 on the frame 1 and reducing shaking. One end of the serpentine spring 3 passes through the insertion interface 10, forming a stable detachable connection with the spring connector 2, reducing up-and-down shaking. Therefore, installing the serpentine spring 3 on the frame 1 through the spring connector 2 not only allows for flexible adjustment of the number and position of the serpentine spring 3, but also achieves a stable detachable connection with the serpentine spring 3.

[0032] Furthermore, refer to Figure 5 and Figure 6 The spring connector 2 has a first hook 9 on surface a, and a second hook 14 on the bottom of the horizontal surface of the bent boss 12. In one embodiment, the first hook 9 and the second hook 14 are formed by stamping. The first hook 9 and the second hook 14 provide additional hooking structures, enabling installation with external protective structures (such as soft netting, protective fabric, etc.). Figure 3 As shown), this fixes, for example, the soft protective net 15 in this application, thereby playing a role in isolation, protection, or beautification, and improving the comfort and aesthetics of the seating.

[0033] According to embodiments of this application, such as Figure 1 and Figure 2 As shown, each of the four corners of the frame 1 is provided with a corner connector 4, and both ends of each corner connector 4 are inserted into the two ends of the splicing pipe 16 through a narrowing part 5. The corner connector 4 and the narrowing part 5 can be used to splice the adjacent ends of the four splicing pipes 16 to form the frame 1 as a whole. Its structure is stable, easy to disassemble and assemble, and suitable for rapid assembly in a variety of usage environments.

[0034] According to another embodiment, the corner connector 4 is generally in the shape of a right angle or a rounded corner (not shown in the figure). The right angle design can provide higher bending stiffness when bearing vertical loads, and the rounded corner has no sharp edges, reducing the risk of personnel collision injury.

[0035] Furthermore, each splicing pipe 16 has several first through holes 6 on its outer wall, and the first through holes 6 extend through to the inner wall of the splicing pipe 16. Each narrowing part 5 has a second through hole 7 at its top and bottom. The first through hole 6 and the second through hole 7 can be used to insert fasteners such as pins, wood bolts, clips or screws, which facilitates the connection and fixation of the frame 1 and the sofa seat.

[0036] It should be noted that, referring to Figure 7 and Figure 8When the serpentine spring 3 is arched, it can provide different elastic deformation spaces when subjected to force, so that it has good elastic compression and buffering ability in the insertion interface 10, thereby effectively improving the rebound force and stability of the connector and ensuring the reset effect of the spring connector 2 during use. When the serpentine spring 3 is flat, it is more suitable for installation in seats with high rigidity requirements and low elasticity requirements.

[0037] According to another embodiment, reference Figure 7 When the spring connector 2 is facing upwards, it operates in a balanced support mode. In this mode, the horizontal height of the insertion interface 10 is lower than the upper surface of the splicing pipe 16. After the end of the serpentine spring 3 passes through the insertion interface 10, the angle between its arched top and the plane of the frame 1 is small, providing uniform elastic support force, suitable for the cushioning needs of conventional seating; while the reference Figure 8 The horizontal height of the insertion interface 10 is basically flush with the upper surface of the splicing pipe 16, which increases the angle between the arched top of the serpentine spring 3 and the plane of the frame 1, thereby enhancing the bulging support force in the central area of ​​the seat. It is suitable for seats that require enhanced lumbar support. By flipping the direction of the spring connector 2, the arched height and support strength of the serpentine spring 3 can be flexibly adjusted without replacing the parts.

[0038] In addition, refer to Figure 9 The side of the spring connector 2 away from surface a can retain only the triangular boss 8 and the insertion interface 10, so that the outer wall of one side of the spring connector 2 is vertical to form surface b. In one embodiment, surface b can be directly welded and fixed to the outer wall of the splicing pipe 16 without being fitted onto the splicing pipe, thereby further reducing manufacturing costs.

[0039] All parts not described in this utility model are the same as or can be implemented using existing technology. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the appended claims and their equivalents.
