Description

Technical Field

[0001] This utility model relates to the field of furniture technology, specifically to a multifunctional swivel chair suitable for home use, featuring an assemblable sunshade structure that balances safety and ease of maintenance. Background Technology

[0002] As people's living standards improve, the demand for home leisure furniture is becoming increasingly diversified. Traditional chairs have relatively simple functions, mostly only providing basic seating, lacking features such as swivel adjustment and sunshade protection, making it difficult to meet users' needs in different scenarios. For example, when used outdoors, users cannot flexibly adjust their seating direction according to the direction of sunlight and are easily affected by sun and rain; when used indoors, it is also not convenient to adjust the seating posture to adapt to the needs of communication or activities.

[0003] Currently, most swivel chairs on the market only have a single swivel function and lack sunshade structures. When used outdoors, people are easily exposed to direct sunlight or rain, resulting in a poor user experience. While some chairs do have sunshades, these are usually fixed to the main body and cannot be disassembled or folded as needed. When the sunshade function is not required, the sunshade takes up a lot of space and is inconvenient for transportation and storage. Furthermore, the base structure of most existing swivel chairs is of fixed size, unable to be flexibly adjusted to the size of the space where it is placed, resulting in low adaptability. Additionally, the structural design of the swivel components is not ideal, easily causing jamming and instability during rotation, affecting user comfort.

[0004] Therefore, it is necessary to improve upon the above-mentioned issues. Utility Model Content

[0015] As a preferred embodiment of this utility model, the locking plate has a wedge-shaped conical structure, and the thickness of the locking plate gradually increases along the insertion direction. This structural design allows the locking plate to achieve a tight fit by adjusting the insertion depth according to the size of the gap between the locking screw and the frame, adapting to the filling requirements of different gap sizes, and improving the versatility and stability of the fixation.

[0016] As a preferred embodiment of this utility model, two symmetrically arranged positioning blocks are fixedly provided on one side of the inner side of the support frame. The positioning blocks have positioning holes adapted to the locking screws at their center. The positioning blocks are arranged one-to-one with the positioning mechanisms of the awning assembly. When the awning assembly is assembled onto the support assembly, the bottom of the locking screws on the positioning mechanisms passes through the positioning mechanisms and the positioning holes in sequence, and is tightened by the locking nuts and the locking screws through threaded engagement, thereby achieving a fixed connection between one side of the awning assembly and the support assembly.

[0017] As a preferred embodiment of this utility model, two symmetrically arranged positioning plates are fixedly installed on the side of the support frame away from the positioning block.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0042] Example

[0043] like Figure 1 , Figure 7 , Figure 8 , Figure 13 and Figure 15As shown, this embodiment provides a multifunctional swivel chair, including a base assembly 1, a support assembly 5, and a sunshade assembly 2. The base assembly 1 and the support assembly 5 are rotatably connected by a turntable assembly 4. The sunshade assembly 2 is detachably mounted on the support assembly 5 to enable quick disassembly and replacement of the sunshade assembly 2. The turntable assembly 4 consists of an upper turntable 40, a lower positioning plate 41, and a positioning cylinder 42. The upper turntable 40 has an upper through hole 43 adapted to the positioning cylinder 42 in its central area, and the lower positioning plate 41 has a lower through hole 44 adapted to the positioning cylinder 42 in its central area. The positioning cylinder 42 passes through the lower through hole 44 and the upper through hole 43 in a vertical direction, and the positioning cylinder 42 is fixedly installed in the lower through hole 44 by welding or interference fit. The upper turntable 40 can rotate smoothly 360° relative to the lower positioning plate 41 with the positioning cylinder 42 as the rotation axis.

[0044] The design of fixing the positioning cylinder 42 to the lower positioning plate 41 and the upper turntable 40 rotating around the positioning cylinder 42 allows for flexible rotation of the base component 1 and the support component 5. Users can freely adjust the sitting and leaning direction according to their needs, improving the convenience of use. At the same time, the positioning cylinder 42 is fixed by welding or interference fit to ensure the structural strength of the rotating component and prevent loosening after long-term use.

[0045] Specifically, the support frame 50 is made of stainless steel tubing with a diameter of 3cm and a ring diameter of 80cm. The reinforcing tubes 51 are made of stainless steel tubing of the same specifications as the support frame 50. A rotating shaft 52 is welded to the center of the intersection of the two reinforcing tubes 51. The lower end of the rotating shaft 52 extends into the positioning cylinder 42. A gap is left between the bottom of the rotating shaft 52 and the connecting bolt 82. A graphite copper sleeve is installed between the rotating shaft 52 and the positioning cylinder 42 to reduce the coefficient of rotational friction and ensure that the upper turntable 40 can rotate smoothly around the positioning cylinder 42. The upper turntable 40 is fastened and welded to the intersection of the two reinforcing tubes 51 with four M6 bolts.

[0046] like Figure 15 As shown, the support assembly 5 includes a ring-shaped closed support frame 50. Two reinforcing tubes 51 are fixedly arranged perpendicularly to each other inside the support frame 50, and the intersection of the two reinforcing tubes 51 forms a stable support node. The upper turntable 40 is fixedly installed at the intersection node of the two reinforcing tubes 51 by bolts or welding. A vertically downward extending rotating shaft 52 is fixedly connected at the center of the intersection of the two reinforcing tubes 51. The outer diameter of the rotating shaft 52 is adapted to the inner diameter of the positioning cylinder 42, and the lower end of the rotating shaft 52 extends into the interior of the positioning cylinder 42, so as to rotate with low friction along the inner wall of the positioning cylinder 42, thereby improving the stability and smoothness of the support assembly 5 during rotation.

[0047] The ring support frame 50, together with the cross reinforcing tube 51, forms a stable support node, which improves the load-bearing capacity and deformation resistance of the support component 5. The matching design of the rotating shaft 52 and the positioning cylinder 42 concentrates the rotation of the support component 5 at the mating point of the rotating shaft 52 and the positioning cylinder 42, reduces rotational friction, avoids jamming, and further ensures smooth rotation and stability.

[0048] Reference Figure 13 and Figure 15 As shown, the upper end face of the positioning cylinder 42 is on the same horizontal plane as the upper end face of the upper turntable 40. This structural design can prevent the upper end of the positioning cylinder 42 from protruding from the surface of the upper turntable 40 to form a protruding structure, preventing personnel from being bumped during use, while ensuring the flatness of the overall structure of the turntable assembly 4.

[0049] The upper surface of the positioning cylinder 42 is flush with the upper surface of the upper turntable 40, eliminating protruding structures and preventing users from being injured by bumps to their legs or hands during use, thus improving safety. At the same time, the flat structure also has a simpler appearance, which meets the aesthetic requirements of modern furniture.

[0050] Reference Figure 9 , Figure 10 and Figure 12 As shown, the base assembly 1 consists of a base frame 10 and a base support device 8. The base frame 10 includes multiple adjustable-length connecting tubes 13. The multiple connecting tubes 13 are spliced ​​together by interlocking their ends to form a polygonal or circular frame structure. The interlocking points of two adjacent connecting tubes 13 are locked and fixed by base screws 11 to achieve flexible adjustment of the overall size of the base frame 10 and adapt to the placement requirements of different usage scenarios.

[0051] Multiple connecting pipes 13 are connected and locked with base screws 11. Users can adjust the connection length of the connecting pipes 13 according to the placement scenario (such as a narrow balcony or an open courtyard), change the overall size of the base frame 10, adapt to different space sizes, and improve the environmental adaptability of the product.

[0052] Reference Figure 12 , Figure 13 and Figure 14 As shown, the base support device 8 includes multiple vertically arranged support pipes 80. The number of support pipes 80 is the same as the number of connecting pipes 13, and the support pipes 80 and connecting pipes 13 are arranged in a one-to-one correspondence. The bottom of each support pipe 80 is fastened to the corresponding connecting pipe 13 by a bottom support bolt 81, and the top of each support pipe 80 is fastened to the outer wall of the positioning cylinder 42 by a connecting bolt 82, forming a stable support structure from the base frame 10 to the positioning cylinder 42.

[0053] The support tube 80 and the connecting tube 13 correspond one-to-one and are fastened to the base frame 10 and the positioning cylinder 42 respectively by bolts, forming a complete support link from the base to the rotating component, dispersing the force, avoiding local stress concentration that could lead to structural damage, and improving the overall load-bearing stability.

[0054] Reference Figure 11 As shown, each connecting pipe 13 is equipped with a foot pad 12 with anti-slip function at its bottom. The foot pad 12 is made of rubber or silicone material, which can increase the friction with the ground and prevent the swivel chair from sliding during use. Multiple foot pads 12 are evenly distributed at equal intervals along the circumferential direction of the base frame 10 to ensure that the base assembly 1 is subjected to uniform force and improve the overall placement stability of the swivel chair.

[0055] The rubber or silicone foot pads 12 increase the coefficient of friction with the ground, effectively preventing the swivel chair from sliding or shifting during use or rotation, and are especially suitable for smooth floors such as ceramic tiles and wooden floors; the foot pads 12 are evenly distributed around the circumference to ensure that the base is evenly stressed and to prevent the chair from tilting due to unbalanced stress.

[0056] Reference Figure 2 As shown, the sunshade assembly 2 adopts a foldable storage structure, including several foldable frames 6, a sunshade fabric 7 for sun and rain protection, and positioning mechanisms 3 assembled at both ends of each frame 6. The sunshade fabric 7 is fixedly connected to the frame 6 by sewing or Velcro. The frame 6 can support and shape the sunshade fabric 7, and when the frame 6 is folded, the sunshade fabric 7 can be folded and stored together with the frame 6, reducing storage space. The foldable frame 6 drives the sunshade fabric 7 to fold, which can greatly reduce the volume of the sunshade assembly 2 when not in use or during transportation, saving storage space and making it easy to carry (such as in camping scenarios). The sunshade fabric 7 is fixed by sewing or Velcro to ensure the support and shaping effect, while realizing the functions of sunshade and rain protection, expanding the outdoor use scenarios.

[0057] Reference Figure 3 and Figure 4 As shown, the positioning mechanism 3 consists of an upper positioning plate 30, a lower positioning plate 31, and a side positioning plate 32. The upper positioning plate 30 and the lower positioning plate 31 are arranged parallel to each other and opposite to each other. The side positioning plate 32 is vertically connected to the same side edge of the upper positioning plate 30 and the lower positioning plate 31. The three together form a positioning groove 33 for accommodating the end of the skeleton 6. The end of the skeleton 6 is embedded in the positioning groove 33, and the skeleton 6 is tightly fitted to the inner wall of the positioning groove 33. At the same time, the positioning screws 34 pass through the upper positioning plate 30, the skeleton 6, and the lower positioning plate 31 in sequence to fasten the skeleton 6 to the positioning mechanism 3.

[0058] The positioning groove 33, formed by the upper positioning plate 30, the lower positioning plate 31, and the side positioning plate 32, forms a wrap-around positioning for the end of the frame 6. Combined with the through-hole fixing of the positioning screws 34, it prevents the frame 6 from loosening or shifting when supporting the sunshade cloth 7, thus ensuring the structural stability of the sunshade assembly 2.

[0059] Reference Figure 4 Locking holes 35 are provided on both sides of the upper positioning plate 30 and the lower positioning plate 31 away from the side positioning plate 32. Locking screws 36 for strengthening fixation are inserted into the locking holes 35. A locking plate 37 is detachably inserted between the locking screws 36 and the outermost frame 6. The locking plate 37 fills the gap between the locking screws 36 and the frame 6, further improving the fixing effect of the positioning mechanism 3 on the frame 6.

[0060] The locking plate 37 fills the gap between the locking screw 36 and the frame 6, preventing the frame 6 from shaking in the positioning groove 33. It is especially suitable for gap problems caused by slight deformation of the frame 6 after long-term use, and further enhances the fixing effect of the positioning mechanism 3 on the frame 6.

[0061] Reference Figure 5 The locking plate 37 has a wedge-shaped conical structure, and the thickness of the locking plate 37 gradually increases along the insertion direction. This structural design allows the locking plate 37 to achieve a tight fit by adjusting the insertion depth according to the size of the gap between the locking screw 36 and the skeleton 6, adapting to the filling requirements of different gap sizes and improving the versatility and stability of the fixation.

[0062] The thickness of the locking plate 37 increases with the insertion direction, and the insertion depth can be adjusted to accommodate different gap sizes (such as the size error of different batches of skeleton 6, the wear gap after use), without the need to replace locking parts of different specifications, thereby improving the versatility of parts and reducing maintenance costs.

[0063] Reference Figure 15 Two symmetrically arranged positioning blocks 20 are fixedly installed on one side of the inner side of the support frame 50. The positioning block 20 has a positioning hole 21 adapted to the locking screw 36 at its center. The positioning block 20 is arranged one-to-one with the positioning mechanism 3 of the sunshade assembly 2. When the sunshade assembly 2 is assembled on the support assembly 5, the bottom of the locking screw 36 on the positioning mechanism 3 passes through the positioning mechanism 3 and the positioning hole 21 in sequence, and is tightened by the locking nut 38 and the locking screw 36 through thread engagement, so as to realize the fixed connection between one side of the sunshade assembly 2 and the support assembly 5.

[0064] The positioning hole 21 of the positioning block 20 is adapted to the locking screw 36 of the positioning mechanism 3 and is tightened by the locking nut 37 to achieve precise positioning and fixation on one side of the sunshade assembly 2, providing a reference for the connection on the other side and ensuring assembly accuracy.

[0065] Reference Figure 15 Two symmetrically arranged positioning plates 22 are fixedly installed on the other side of the support frame 50 away from the positioning block 20. The positioning plates 22 are provided with connection holes 23 that are adapted to the U-bolts 24. The frame 6 of the sunshade assembly 2 is placed on the positioning plate 22. The open end of the U-bolt 24 passes through the connection hole 23 and wraps around the frame 6. Then, the positioning nut 25 is used to engage with the threaded end of the U-bolt 24 to fasten it, thereby realizing the fixed connection between the other side of the sunshade assembly 2 and the support assembly 5. With the connection structure at the positioning block 20, the overall assembly stability of the sunshade assembly 2 is ensured.

[0066] U-bolts 24 wrap around the frame 6 and are fastened by positioning nuts 25. Together with the fixing structure at the positioning block 20, they achieve symmetrical fixing on both sides of the awning assembly 2, avoiding tilting and shaking caused by fixing on one side, and ensuring the overall stability of the awning assembly 2 after assembly.

[0067] Reference Figure 6 and Figure 9 The upper and lower edges of the awning assembly 2 are fixedly fitted with Velcro 9, which includes a hook side and a rough side that cooperate with each other. After the awning assembly 2 is assembled, by attaching the hook side and the rough side of the Velcro 9, the positioning mechanism 3 and the connection part between the positioning mechanism 3 and the support assembly 5 can be covered. On the one hand, this avoids the screws, nuts and other parts of the connection part from being exposed and causing bumps. On the other hand, it improves the appearance of the awning assembly 2.

[0068] The Velcro 9 covers the positioning mechanism 3 and the connecting parts, hiding metal parts such as screws and nuts, preventing users from touching and scratching them, while also covering the connection gaps, improving the appearance of the sunshade assembly 2, and preventing dust and rainwater from entering the connecting parts and causing them to rust.

[0069] In this embodiment, the method for using and adjusting the swivel chair is as follows:

[0070] 1. Loosen the base screw 11, pull the connecting tube 13 to adjust the sleeve length, and after the size of the base frame 10 is suitable for the placement space, tighten the base screw 11 to fix it.

[0071] 2. The user sits on the seat of the support component 5 (which can be paired with the seat cushion 14) and pushes his body to make the support component 5 rotate 360° around the positioning cylinder 42 to adjust to the desired direction.

[0072] 3. Unfold the awning assembly 2, align the positioning mechanism 3 with the positioning block 20 of the support frame 50, and screw the locking screw 36 through the positioning mechanism 3 and the positioning hole 2) into the locking nut 38 to fix it; then place the frame 6 on the positioning plate 22, wrap the frame 6 with the U-bolt 24 and pass it through the connection hole 23, and screw in the positioning nut 25 to tighten it; finally, attach the Velcro 9 to cover the connection part.
