[0002] Office chairs refer to various chairs provided for convenience in daily work and social activities. Office partners divide office chairs into narrow and broad definitions. In a narrow sense, office chairs refer to backrest chairs used when people are working at a desk in a seated position. In a broad sense, office chairs refer to all chairs used in offices, including executive chairs, mid-level chairs, guest chairs, staff chairs, conference chairs, visitor chairs, training chairs, etc.

[0003] A portable office chair, disclosed in Chinese Patent Publication No. CN221931611U, comprises a seat, a cushion, and a support beam. The seat has an inwardly recessed mounting groove with sliding grooves on both its front and rear sides. A cushion is placed within the mounting groove, and sliding ribs are symmetrically arranged on both the front and rear sides of the cushion. The cushion is inserted downwards onto the seat, with the sliding ribs corresponding to the sliding grooves. The support beam includes longitudinal beams and transverse beams, assembled in an L-shape. There are two longitudinal beams, one on each side, with two beams on each side. The length of the right longitudinal beam is half the length of the left longitudinal beam.

[0004] In the above solution, the seat is folded using a universal joint, adjustment groove, locking bolt, and locking block, which results in the following disadvantage: the locking bolt needs to be repeatedly loosened or tightened when folding the seat, requiring the use of additional auxiliary tools. Utility Model Content

[0005] The purpose of this invention is to provide a portable office chair to solve the problem that the chair needs to be repeatedly loosened or tightened when folded, requiring additional auxiliary tools.

[0006] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: a portable office chair, including a seat plate, the seat plate being rotatably disposed inside a support frame, support rods being rotatably disposed on the left and right sides of the seat plate, and rotating holes being opened on the outer sides of the two support rods and the left and right sides of the outer wall of the support frame, respectively; two rotating columns being fixed on the left and right sides of the seat plate, the two rotating columns being rotatably disposed in the two rotating holes, and turntables being fixed at the outer ends of the two rotating columns, with fixing grooves opened on the outer sides of the two turntables; L-shaped plates being fixed on the left and right sides of the seat plate and the left and right sides of the outer wall of the support frame, and fixing holes being opened on one side of the two L-shaped plates, with fixing columns slidably inserted into the two fixing holes, the fixing columns being slidably inserted into the fixing grooves, and stop blocks being fixed at the outer ends of the two fixing columns, with springs fixed between the two stop blocks and the two L-shaped plates, and the two springs being wrapped around the two fixing columns.

[0007] Preferably, a bearing plate is fixed inside the support frame, the top surface of the bearing plate is in contact with the bottom surface of the seat plate, and two blocking plates are fixed to the bottom surface of the seat plate, with the rear side of each of the two blocking plates in contact with the front side of the two support rods.

[0008] Preferably, the inner wall of the support frame has storage slots on the left and right sides respectively.

[0009] Preferably, a connecting plate is detachably installed between the support frame and the two support rods.

[0010] Preferably, the outer sides of the two support rods and the left and right sides of the outer wall of the support frame are provided with snap-fit ​​holes, and the inner sides of the two connecting plates are fixed with two elastic snap-fit ​​blocks, which are detachably snapped into the two snap-fit ​​holes respectively.

[0011] Preferably, the bottom surface of the support frame is fixed with two first anti-slip blocks, and the bottom surfaces of the two support rods are respectively fixed with second anti-slip blocks.

[0012] Compared with existing technologies, a portable office chair that adopts the above-mentioned technical solution has the following beneficial effects:

[0013] First, during use, the seat board, support frame, support rod, rotating hole, rotating column, turntable, fixing groove, L-shaped plate, fixing hole, fixing column, stop block and spring work together to help staff quickly fold and store the chair. The operation is simple and convenient, without the need for additional auxiliary tools, saving time and effort. At the same time, the foldable design improves the portability of the chair, making it convenient for staff to carry and use in different scenarios.

[0014] Second, during use, the support plate provides additional support to the seat. Under the weight of the worker, the support plate can evenly distribute the pressure, effectively enhancing the seat's load-bearing capacity and improving the seat's stability. Simultaneously, the two baffles prevent the support rods from sliding forward or shifting under external forces, further ensuring the stability of the seat structure. This makes the seat more compact when folded, saving storage space. The connection method effectively enhances the seat's stability, ensuring that the seat will not wobble or loosen when the worker sits on it.

[0015] Third, the chair is simple and convenient to operate, saving time and labor costs while improving its flexibility. The first and second anti-slip blocks fit tightly against the contact surface, increasing friction between the chair and the ground, preventing easy slippage or displacement, and effectively ensuring the safety and stability of the workers.

[0021] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] like Figures 1-4As shown, a portable office chair includes a seat 1, which is rotatably disposed inside a support frame 2. Support rods 3 are rotatably disposed on the left and right sides of the seat 1. Rotation holes 4 are provided on the outer sides of the two support rods 3 and the outer walls of the support frame 2 on the left and right sides, respectively. Two rotating columns 5 are fixed to the left and right sides of the seat 1, and are rotatably disposed within the two rotating holes 4. A turntable 6 is fixed to the outer end of each of the two rotating columns 5. A fixing groove 7 is provided on the outer side of each of the two turntables 6. L-shaped plates 8 are fixed to the left and right sides of the seat 1 and the outer walls of the support frame 2 on the left and right sides, respectively. A fixing hole 9 is provided on one side of each of the two L-shaped plates 8. A fixing post 10 is slidably inserted into each of the two fixing holes 9 and is slidably inserted into the fixing groove 7. A stop block 11 is fixed to the outer end of each of the two fixing posts 10. A spring 12 is fixed between each stop block 11 and each of the two L-shaped plates 8, and the two springs 12 are wrapped around the two fixing posts 10.

[0023] During use, when the staff needs to fold and store the chair, firstly, the staff grasps the stops 11 on the L-shaped plates 8 on both sides of the seat 1 and pulls them outwards. At this time, the spring 12 connected to the stops 11 is stretched, producing elastic deformation. Simultaneously, the fixing post 10 disengages from the fixing groove 7 on the turntable 6 under the action of external force. Next, the staff rotates the support rod 3 counterclockwise by 90 degrees, so that the support rod 3 is parallel to the seat 1. Then, the staff releases the stops 11. Under the action of the elastic restoring force of the spring 12, the fixing post 10 automatically resets and slides into another pre-set groove on the turntable 6. The support rod 3 is securely fixed in the pre-designed fixing groove 7 after rotation. After the support rod 3 is folded and fixed, the staff operates the stops 11 of the two L-shaped plates 8 on the support frame 2 in the same way. Pulling the stops 11 makes the fixing column 10 disengage from the fixing groove 7 on the turntable 6. Then, the seat 1 is rotated 90 degrees clockwise so that the seat 1 is parallel to the support frame 2. Finally, the stops 11 are released, and the spring 12 plays its role again, automatically resetting the fixing column 10 and inserting it into the corresponding fixing groove 7 on the turntable 6, thus completing the folding and fixing of the seat 1. At this point, the entire seat is folded and stored. The combination of seat 1, support frame 2, support rod 3, rotating hole 4, rotating column 5, turntable 6, fixing groove 7, L-shaped plate 8, fixing hole 9, fixing column 10, stop block 11 and spring 12 allows staff to quickly fold and store the chair. The operation is simple and convenient, requiring no additional auxiliary tools, saving time and effort. At the same time, the foldable design improves the portability of the chair, making it convenient for staff to carry and use in different scenarios.

[0024] like Figures 1-4 As shown, a bearing plate 13 is fixed inside the support frame 2. The top surface of the bearing plate 13 is in contact with the bottom surface of the seat plate 1. Two baffle plates 14 are fixed on the bottom surface of the seat plate 1. The rear sides of the two baffle plates 14 are in contact with the front sides of the two support rods 3.

[0025] During use, when the staff sits on the seat 1, the support plate 13 provides additional support for the seat 1. Under the pressure of the staff's weight, the support plate 13 can evenly distribute the pressure, effectively enhancing the load-bearing capacity of the seat 1 and improving the stability of the seat. At the same time, the two baffles 14 can prevent the support rod 3 from sliding forward or shifting under the action of external force, further ensuring the stability of the seat structure.

[0026] like Figures 1-4 As shown, storage slots 15 are respectively opened on the left and right sides of the inner wall of the support frame 2, and connecting plates 16 are detachably installed between the support frame 2 and the two support rods 3.

[0027] During use, when the operator follows the steps described above to rotate the support rod 3 counterclockwise to make it parallel to the seat 1, and then rotates the seat 1 clockwise to make it parallel to the support frame 2, the support rod 3 can be neatly stored in the storage slot 15. This makes the seat more compact after folding, saving storage space. When the seat is in the unfolded state, the operator installs the connecting plate 16 between the support rod 3 and the support frame 2. Through the connection of the connecting plate 16, the support rod 3, the support frame 2, and the seat 1 form a stable overall structure. This connection method effectively enhances the stability of the seat, ensuring that the seat will not shake or loosen when the operator sits on it.

[0028] like Figures 1-4 As shown, the outer sides of the two support rods 3 and the left and right sides of the outer wall of the support frame 2 are provided with snap-fit ​​holes 17. The inner sides of the two connecting plates 16 are each fixed with two elastic snap-fit ​​blocks 18. The two elastic snap-fit ​​blocks 18 are respectively detachably snapped into the two snap-fit ​​holes 17. The bottom surface of the support frame 2 is fixed with two first anti-slip blocks 19, and the bottom surfaces of the two support rods 3 are respectively fixed with second anti-slip blocks 20.

[0029] During use, when the connecting plate 16 needs to be installed, the operator simply aligns the elastic locking block 18 on the inner side of the connecting plate 16 with the locking hole 17, and then presses the connecting plate 16. Under the action of external force, the elastic locking block 18 undergoes elastic deformation and smoothly locks into the locking hole 17, achieving quick installation of the connecting plate 16. When the connecting plate 16 needs to be disassembled, the operator simply pulls the connecting plate 16 outward or squeezes the elastic locking block 18. Under the action of tension, the elastic locking block 18 undergoes elastic deformation again and disengages from the locking hole 17, completing the disassembly of the connecting plate 16. The operation is simple and convenient, saving not only time and labor costs but also improving the flexibility of the chair's use. When the operator places the chair on the ground or other working surfaces, the first anti-slip block 19 and the second anti-slip block 20 are in close contact with the contact surface, increasing the friction between the chair and the ground, preventing easy slippage or displacement, and effectively ensuring the operator's working safety and stability.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
