[0016] A further technical solution is that a number of fifth through holes are longitudinally spaced at the connection points of two adjacent backrests, and the outer contour of the longitudinal section of the fifth through hole is a downwardly bent arc structure.

[0017] A further technical solution is that the stool base is also provided with a support leg, the bottom end of the support leg is connected to the top end of the stool base, the top end of the support leg is connected to a support plate, and the top end of the support plate is connected to the bottom end of the stool panel.

[0018] The beneficial effects of this utility model embodiment are as follows:

[0019] (I) A double stool includes a stool base, a stool panel and a backrest. The stool panel is disposed on the base and has two first through holes that are horizontally opened to correspond to the contact area of ​​the buttocks. The first through holes are provided with a breathable mesh. The backrest is vertically connected to the rear end of the panel and has a second through hole and a breathable mesh corresponding to the contact area of ​​the back. During use, when the buttocks and back of the human body contact the first through holes and the second through holes, the breathable mesh on the first through holes and the second through holes enhances the air circulation between the stool panel and the backrest, reduces stuffiness, and improves the heat dissipation efficiency of the stool panel and the backrest. Furthermore, when the buttocks and back of the human body contact the breathable mesh, the breathable mesh undergoes elastic deformation with the pressure of the human body, conforms to the body curve, is more ergonomic, and improves the comfort of the stool panel and the backrest.

[0020] (ii) Furthermore, the outer contour of the cross-section of the seat panel is an arc-shaped structure that bends backward, and the outer contour of the cross-section of the two first through holes on the left and right sides is an arc-shaped structure that bends to the right and left sides. This more accurately fits the curve of the human buttocks when sitting, distributing the pressure of sitting to the periphery of the ischial tuberosities. Moreover, due to the shape and structure of the seat panel and the setting of the first through holes, the area of ​​the seat panel is smaller than that of a traditional seat, which improves the utilization rate of the seat panel area and reduces the weight of the seat panel.

[0021] (III) Furthermore, a tabletop base is provided between two adjacent stool bases. A support rod is mounted on the tabletop base, with one end connected to the tabletop base and the other end connected to the joint between the two backrests. A tabletop is horizontally mounted on the support rod, and its height is higher than the stool panel. The longitudinal section of the support rod has a second arc-shaped structure bent forward, while the cross-sectional outline of the tabletop has a first arc-shaped structure bent forward. The tabletop primarily serves as a functional extension area. Its height is slightly higher than the stool panel, aligning with the natural working angle of the elbows when seated. The arc-shaped cross-sections of the tabletop and support rod maintain sufficient rigidity while saving materials, thus enhancing the functionality of the double stool.

[0022] (iv) Furthermore, the outer contour of the backrest's cross-section is a backward-bending arc structure, and this arc structure corresponds to the area of ​​contact between the back and the human body in a sitting posture. Several fourth through holes are provided on the backrest, spaced apart along the outer contour of the second through holes. The longitudinal cross-section of the fourth through holes is a second arc structure that bends outward. The arc structure of the backrest conforms to the natural curve of the human back, increasing the contact area between the back and the backrest, dispersing the concentrated pressure of a traditional flat backrest into multi-point support, reducing back pressure, and making it more ergonomic and improving comfort. The spaced fourth through holes along the outer contour of the second through holes further enhance the breathability and heat dissipation of the backrest, and the hollowed-out backrest further reduces its weight, achieving a lightweight design for the double seat.

[0032] Example:

[0033] Figure 1 This is a front view structural diagram of a double-seat stool according to the present invention. Figure 2 This is a top view schematic diagram of a two-person stool according to this utility model. Figures 1-2As shown, a double stool includes a stool base 100, a stool panel 200, and a backrest 300. The stool base 100 has at least two sections, with its bottom end resting on the ground. The stool panel 200 has at least two sections, each disposed on the stool base 100. Two first through holes 201 are horizontally spaced apart on the stool panel 200, corresponding to the area where the buttocks of a seated person contact the seat. The first through holes 201 are provided with a breathable mesh surface. For example, the stool base 100 also includes support legs 101, with the bottom end of the support legs 101 connected to the top end of the stool base 100. A support plate 102 is connected to the top end of the support legs 101, and the top end of the support plate 102 is connected to the bottom end of the stool panel 200. The backrest 300 has at least two backrests, which are vertically disposed at the rear end of the seat panel 200. A second through hole 301 is provided on the backrest 300, which corresponds to the area in contact with the back of the human body when sitting. A breathable mesh is provided on the second through hole 301. Two adjacent backrests 300 are connected together.

[0034] like Figure 2 As shown, the outer contour of the cross-section of the seat panel 200 is a first arc-shaped structure 700 that bends backward, and the outer contour of the cross-section of the two first through holes 201 on the left and right sides is a first arc-shaped structure 700 that bends to the right and left sides. This more accurately fits the curve of the human buttocks in a sitting posture, distributing the sitting pressure to the periphery of the ischial tuberosities. Furthermore, due to the shape and structure of the seat panel 200 and the setting of the first through holes 201, the area of ​​the seat panel 200 is smaller than that of a traditional seat, improving the utilization rate of the seat panel 200 area and reducing the weight of the seat panel 200.

[0035] like Figure 2 As shown, furthermore, a connecting rod 400 is connected to the front ends of two adjacent stool panels 200 on their sides, with the cross-sectional outer contour of the connecting rod 400 being a second arc-shaped structure 800 that bends forward. The connection rod 400 enhances the installation stability of the two stool panels 200. At the same time, the second arc-shaped structure 800 of the connecting rod 400 provides a stress buffer at the panel connection, eliminating the risk of hard contact between direct connectors and enhancing the strength of the connection of the connecting rod 400.

[0036] Figure 3 This is a side view of the structure of a double-seat stool according to this utility model. Figure 3As shown, a tabletop base 500 is further provided between two adjacent stool bases 100. A support rod 501 is provided on the tabletop base 500. One end of the support rod 501 is connected to the tabletop base 500, and the other end is connected to the connection point of the two backrests 300. A tabletop 600 is horizontally mounted on the support rod 501, and the height of the tabletop 600 is higher than that of the stool panel 200. The longitudinal section of the support rod 501 has a forward-bending second arc-shaped structure 800, and the cross-sectional outline of the tabletop 600 has a forward-bending first arc-shaped structure 700. The tabletop 600 is mainly used as a functional extension area. The tabletop height is slightly higher than that of the stool panel 200, which conforms to the working angle of the elbow naturally hanging down when sitting. The arc-shaped sections of the tabletop 600 and the support rod 501 maintain sufficient rigidity while saving materials, thus improving the functionality of the double stool.

[0037] like Figure 2 As shown, the desktop panel 600 further includes several third through holes 601. The third through holes 601 on the desktop panel 600 achieve the basic ventilation function of the desktop panel 600 through a uniform hole array, which reduces heat accumulation on the contact surface between the desktop and the object, and avoids excessive openings from affecting the load-bearing performance.

[0038] like Figure 3 As shown, a rotating shaft 502 is provided at the connection between the support rod 501 and the desktop 600. The bottom end of the rotating shaft 502 is rotatably connected to the support rod 501, and the bottom end of the desktop 600 is rotatably located at the top end of the support rod 501. The desktop 600 can be rotated to switch different orientations according to usage requirements, meeting different user needs, increasing the applicability of the desktop 600, and improving the functionality of the desktop 600.

[0039] like Figure 2 As shown, furthermore, the outer contour of the cross-section of the backrest 300 is a second arc-shaped structure 800 that bends backward, and the second arc-shaped structure 800 of the backrest 300 corresponds to the area of ​​contact between the back of the human body in a sitting posture. Several fourth through holes 302 are provided on the backrest 300, and the fourth through holes 302 are spaced apart along the outer contour of the second through holes 301. The outer contour of the longitudinal section of the fourth through holes 302 is a second arc-shaped structure 800 that bends outward. The second arc-shaped structure 800 of the backrest 300 conforms to the natural curve of the human back, increasing the contact area between the human back and the backrest 300, dispersing the concentrated pressure of the traditional flat backrest 300 into multi-point support, reducing back pressure, making it more ergonomic, and improving the comfort of the backrest 300. The spaced distribution of the fourth through holes 302 along the outer contour of the second through holes 301 further improves the breathability and heat dissipation of the backrest 300, and the hollowed-out backrest 300 further reduces the weight of the backrest 300, achieving a lightweight design for the double seat.

[0040] like Figure 1 As shown, furthermore, several fifth through holes 303 are longitudinally spaced at the connection between two adjacent backrests 300. The outer contour of the longitudinal section of the fifth through hole 303 is a first arc structure 700 that bends downward. The design of the fifth through hole 303 also improves the ventilation and heat dissipation effect of the backrest 300. The hollow design reduces the weight of the double seat and realizes the lightweight design of the double seat.

[0041] Figure 4 This is a schematic diagram of the first arc-shaped structure in a double-seat stool according to the present invention. Figure 5 This is a schematic diagram of the second arc-shaped structure in a double-seat stool according to this utility model. Figures 4-5 As shown, specifically, the first arc-shaped structure 700 described above is composed of a first arc segment 710 and a second arc segment 720 that transition continuously. The center of curvature of the first arc segment 710 is located on the inner side of the cross-section, forming a curve that convexes outward. The second arc segment 720 connects to the middle region of the first arc segment 710, and its center of curvature is located on the outer side of the cross-section, forming a curve that concaves inward. The junction of the first arc segment 710 and the second arc segment 720 is smoothly connected by a first connecting segment 730 with a continuous transition in curvature. The curvature on the first arc segment 710 is not equal to the curvature on the second arc segment 720, so that the overall shape of the cross-sectional profile presents a quasi-elliptical structure with local concave deformation on one side.

[0042] The second arc-shaped structure 800 is composed of a continuously transitioning third arc segment 810 and a fourth arc segment 820. The center of curvature of the third arc segment 810 is located on the outer side of the cross-section, forming a curve that convexes outward. The fourth arc segment 820 connects to the middle region of the third arc segment 810, and its center of curvature is located on the outer side of the cross-section, forming a curve that concaves inward. The junction of the first arc segment 710 and the second arc segment 720 is smoothly connected by a second connecting segment 830 with continuously transitioning curvature. The curvature on the third arc segment 810 is equal to the curvature on the fourth arc segment 820, so that the overall shape of the cross-sectional profile presents a curved strip structure.

[0043] In this embodiment, the breathable mesh on the first through hole 201 and the second through hole 301 enhances the air circulation between the seat panel 200 and the backrest 300, reduces stuffiness, and improves the heat dissipation efficiency of the seat panel 200 and the backrest 300. Furthermore, when the human buttocks and back come into contact with the breathable mesh, the breathable mesh undergoes elastic deformation with the pressure of the human body, conforming to the body curves, which is more ergonomic and improves the comfort of the seat panel 200 and the backrest 300.

[0044] 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.

[0045] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
