Technical Field
[0001] The utility model belongs to the technical field of office chairs, and in particular relates to a high-load-bearing multifunctional swivel chair. Background Art
[0002] A swivel chair is a chair designed to provide comfortable sitting, with a base that can rotate 360° and is usually equipped with wheels to facilitate easy movement on a horizontal surface. Swivel chairs are widely used in offices, home workspaces, meeting rooms, and other places where sitting and working for long periods of time are required.
[0003] The existing swivel chair has a large seat surface area, but due to posture problems, the occupant often cannot sit completely on the seat surface, but only sits on a small part of the seat surface, which generates a large pressure on the local seat surface, especially when the seat surface is subjected to a large load, it is easy to collapse.
[0004] In summary, a swivel chair with strong load-bearing capacity is currently needed. Utility Model Content
[0005] The utility model aims to provide a high-load-bearing multifunctional swivel chair. The swivel chair adds a spring between the movable seat surface and the bottom of the inner cavity of the groove, so that the user's weight is evenly distributed on the entire seat under the transfer of the spring, thereby reducing the pressure on the local part of the seat and improving its load-bearing capacity.

Flexible cushion materials include memory foam, high-density foam, etc., which have good elasticity and support.
[0020] In summary, the utility model has the following benefits:
[0021] 1. The utility model adds springs at equal distances between the movable seat surface and the bottom of the inner cavity of the groove, so that when the user sits on the movable seat surface, the movable seat surface will compress the spring, which plays a certain buffering role, so that the user's weight is evenly distributed on the entire seat under the transfer of the spring, thereby reducing the local pressure on the seat and improving its load-bearing capacity.
[0022] 2. When a heavier user sits on the movable seat surface, the spring can be compressed to perform buffering, so that the vertical rod can also be driven to move downward. By utilizing the hinged effect between the vertical rod and the movable rod and the connecting rod, and the movable cooperation between the movable rod and the bar frame, the two groups of movable rods can be pushed to move back to each other. When the movable rod moves to the other side of the bar frame, it cannot move further due to obstruction. At this time, the movable seat surface can be supported at multiple points, which not only protects the movable seat surface and prevents it from being damaged by excessive pressure, but also further improves the overall load-bearing capacity of the swivel chair.

After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
[0031] Example:
[0032] A seat 1 is provided with a groove on the top of the seat 1, a movable seat surface 2 is movably arranged inside the groove, a spring 3 is equidistantly arranged between the bottom of the movable seat surface 2 and the bottom of the inner cavity of the groove, a seat back 4 is fixedly connected to one side of the seat 1, a bracket 5 is symmetrically fixedly connected to the bottom of the seat 1, a connecting plate is fixedly connected between the two sets of brackets 5, a supporting foot 6 is fixedly connected to the bottom center of the connecting plate, a universal wheel 7 is rotatably connected to the bottom of the supporting foot 6, a positioning column 8 is fixedly connected to the bottom of the movable seat surface 2 and the bottom of the inner cavity of the groove corresponding to the position of the spring 3, which can To prevent the position of the spring 3 from shifting, armrests 9 are fixedly connected to both sides of the seat 1. Flexible cushions are added to the outside of the armrests 9 to facilitate the placement of the user's hands and increase the comfort when placing the hands. The backrest 4 is a curved structure. A lumbar pillow 10 and a headrest 11 are fixedly connected to the backrest 4. The curve shape is convenient for fitting the user's back. The lumbar pillow 10 and the headrest 11 can increase the comfort of the user's waist and neck. A locking piece is provided on the universal wheel 7, which can lock the universal wheel 7 to prevent the swivel chair from moving.
[0033] The auxiliary support assembly includes four groups of vertical rods 101 symmetrically fixedly connected to both sides of the bottom of the movable seat surface 2 and slidably connected to the seat 1. Both sides of the bracket 5 are fixedly connected with a strip frame 102. The two groups of strip frames 102 on the same side are internally movably connected with the same movable rod 103. The movable rod 103 and the two groups of vertical rods 101 on the same side are hinged with a connecting rod 104 through a hinge. Both ends of the movable rod 103 are fixedly connected to a limiting plate 105. The height of the inner side surface of the strip frame 102 is consistent with the height of the movable rod 103.
[0034] The implementation principle of a high-load-bearing multifunctional swivel chair in the embodiment of the present application is as follows: the swivel chair can be moved to a desired position by using universal wheels 7, and when it reaches the specified position, the universal wheels 7 are locked by using a locking piece, and when the user takes a seat, springs 3 are equidistantly provided between the movable seat surface 2 and the bottom of the inner cavity of the groove, so that when the user sits on the movable seat surface 2, the movable seat surface 2 will compress the spring 3, thereby playing a certain buffering role, avoiding the user's weight directly acting on the swivel chair, thereby reducing the local force on the seat, and ensuring the overall structural strength of the swivel chair, and when a heavier user sits on the movable seat surface 2, the spring 3 is compressed for buffering, so that it can also drive the vertical rod 101 to move downward together. By utilizing the hinged connection between the vertical rod 101 and the movable rod 103 and the connecting rod 104, and the movable cooperation between the movable rod 103 and the bar frame 102, the two groups of movable rods 103 can be pushed to move back to each other. When the movable rod 103 moves to the other side of the bar frame 102, it cannot continue to move due to the obstruction. At this time, it can provide multi-point support for the movable seat surface 2, which not only protects the movable seat surface 2 and prevents it from being damaged by excessive pressure, but also improves the overall load-bearing capacity of the swivel chair, further protecting the swivel chair. When the user leans on the chair back 4, its curved structure can better fit the user's back. At the same time, the lumbar pillow 10 and the headrest 11 can support the user's waist and neck.
