Detailed Implementation

[0019] like Figure 1As shown, this utility model discloses a seat connection structure, including a fixed rod 1 and an elastic element 2. The lower end of the elastic element 2 is connected to the upper end of the fixed rod 1, and the lower end of the fixed rod 1 is connected to the seat base. The elastic element 2 includes an elastic part 3, a first connecting part 4, and a second connecting part 5. The first connecting part 4 and the second connecting part 5 are respectively located at both ends of the elastic part 3. The first connecting part 4 is connected to the fixed rod 1, and the second connecting part 5 is connected to the seat support. This arrangement allows the user to rock the seat while sitting, improving comfort. The seat base generally supports the seat and usually has casters at the bottom for easy movement. The seat support generally provides support and mounts the seat cushion and backrest. The elastic part 3 is curved, while the first connecting part 4 and the second connecting part 5 are both flat. The elastic element 2 is generally integrally formed.

[0020] like Figure 2 and Figure 3 As shown, in one implementation, a connecting rod 6 is provided between the fixed rod 1 and the elastic element 2. The connecting rod 6 is arranged laterally and has at least one elastic element 2. This arrangement serves as a transition between the fixed rod 1 and the elastic element 2, making the installation and fixing of the elastic element 2 more convenient. Furthermore, the laterally arranged connecting rod 6 allows for the convenient installation of multiple elastic elements 2 on the fixed rod 1. Compared to a single elastic element 2, multiple elastic elements 2 can utilize elements with lower strength, toughness, and elasticity requirements, thereby saving production costs without affecting the strength and service life of the seat. Generally, two elastic elements 2 are provided, symmetrically arranged at both ends of the connecting rod 6.

[0021] Specifically, the connecting rod 6 is provided with a fixing hole 7, and the fixing rod 1 passes through the fixing hole 7 and is fixedly connected to the connecting rod 6. This arrangement enables the connection between the fixing rod 1 and the connecting rod 6, and the through-hole connection effectively improves the connection strength between the connecting rod 6 and the fixing rod 1. If one side of the connecting rod 6 is connected to and welded to the fixing rod 1, the connection strength is far lower than the connection strength if the fixing rod 1 passes through the connecting hole and is welded to both sides of the connecting rod 6.

[0022] like Figures 4 to 6 As shown, in this embodiment, the first connecting part 4 is provided with a first connecting hole 8, and the connecting rod 6 is provided with a second connecting hole 9 and a fixing bolt 10. The fixing bolt 10 passes through the first connecting hole 8 and the second connecting hole 9 to fix the first connecting part 4. With the above arrangement, the connection between the first connecting part 4 and the connecting rod 6 can be facilitated, which facilitates the assembly of the seat.

[0023] As one implementation, the second connecting part 5 is provided with a third connecting hole 11. This arrangement facilitates the connection between the second connecting part 5 and the support base.

[0024] Specifically, the length of the first connecting part 4 is longer than that of the second connecting part 5 so that the first connecting hole 8 and the second connecting hole 9 are staggered. This arrangement facilitates the assembly of the elastic element 2. When the first connecting part 4 is connected to the connecting rod 6, the shorter second connecting part 5 does not obstruct the space above the first connecting part 4, providing more assembly space for the second connecting part 5 and facilitating the connection between the elastic element 2 and the connecting rod 6. Simultaneously, the staggered design ensures that the fixing bolt 10 does not affect the assembly of the second connecting part 5, improving the overall assembly efficiency of the seat.

[0025] In this embodiment, the elastic element 2 is generally J-shaped. This design ensures that when the seat shakes, the lever arm of the upper support is smaller than that of the lower base, resulting in a faster response, greater deformation, and more elasticity when the seat shakes.

[0026] As one implementation, both the first connecting part 4 and the connecting rod 6 are provided with a washer 12, and the washer 12 has a fourth connecting hole 13 for the fixing bolt 10 to pass through. The washer 12 can improve the connection effect between the first connecting part 4 and the connecting rod 6, and also provides a certain degree of protection for the first connecting part 4 and the connecting rod 6. The washer 12 can increase the contact area with the first connecting part 4 and the connecting rod 6, making the connection between the two more stable and ensuring a stable connection effect even after long-term shaking.

[0027] like Figure 7 As shown, as one implementation method, the fixing rod 1 is a hollow tubular structure. The tubular fixing rod 1 can reduce its weight and provide two different ways of combining with the base. One is that the bottom also uses a tubular connector with the same inner diameter as the outer diameter of the fixing rod 1, which allows the fixing rod 1 to be inserted into the base. The other is that a solid rod can extend into the fixing rod 1. The solid rod connection method can increase the contact area with the fixing rod 1 and improve the connection effect.

[0028] Specifically, a fixing groove 14 is provided on the outer side of the fixing rod 1. The fixing groove 14 can facilitate the base to engage with the fixing rod 1, thus facilitating the connection of the fixing rod 1.

[0029] This utility model also discloses a seat that adopts the above-mentioned seat connection structure.

[0030] This utility model provides an elastic connection structure between the seat support and the base, including a fixed rod 1 and an elastic element 2. The lower end of the elastic element 2 is connected to the upper end of the fixed rod 1, the lower end of the fixed rod 1 is connected to the base of the seat, and the upper end of the elastic element 2 is connected to the seat support. This allows the user to rock the seat cushion while sitting on the support, improving comfort.

[0031] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
