Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of seats, in particular to a multifunctional office seat. Background Art
[0002] An office chair is a seat that can be used by office workers when they are working. In the prior art, there are many types of seats, and the lumbar support of the seats can be rotated and adjusted and has a retractable foot pad. However, in the prior art, the retractable foot pad is mostly retracted by a single rod. In order not to affect the restriction of the foot pad on the legs of the worker when retracted, the length of the single rod must not exceed the length of the seat cushion. For people with long legs, when the foot pad moves to the maximum stroke, the worker lies on the seat to rest, and the foot pad can only support the calf part of the worker, so it cannot fully support the worker's feet, causing the worker's feet to hang in the air, and the muscles and blood vessels in the calf part of the worker are easily compressed when pressed on the foot pad, reducing the comfort of the human body when resting. Utility Model Content
[0003] The utility model aims to solve the shortcomings in the prior art and proposes a multifunctional office chair.
[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is: a multifunctional office chair, including a lumbar support, armrests, a seat cushion, a foot pad, a hydraulic telescopic rod, a pulley and a seat bracket, two fixed tubes are provided under the seat cushion, one end of the fixed tube is movably connected with a movable tube, one end of the movable tube is movably connected with a movable rod, and the two ends of the foot pad are respectively connected to one end of the two movable rods.
[0005] Preferably, the lumbar support is installed on the side of the seat cushion.
[0006] Preferably, the two armrests are mounted on two symmetrical sides of the seat cushion.
[0007] Preferably, the seat bracket is located below the seat cushion, the movable end of the hydraulic telescopic rod is installed at the bottom of the seat cushion, the bottom end of the hydraulic telescopic rod is installed at the top of the seat bracket, and a plurality of pulleys are installed at the bottom end of the seat bracket.
[0008] Preferably, a plurality of support members are installed between the outside of the two fixing tubes and the bottom of the seat cushion.
[0009] Preferably, the other ends of the movable tube and the movable rod are both installed with a second limiting ring, and one ends of the fixed tube and the movable tube are both installed with a first limiting ring, and the second limiting ring is in contact with the side surface of the first limiting ring.
[0010] Compared with the prior art, the utility model has the following beneficial effects:
[0011] In this solution, a slidable movable tube is arranged in a fixed tube, and a slidable movable rod is arranged in the movable tube. Compared with the single-stage telescopic method in the prior art, this solution can extend the extension length of the foot pad through a two-stage telescopic method, thereby making it easier for workers with longer legs to contact the foot pad in the lounge, thereby facilitating the use of the workers. BRIEF DESCRIPTION OF THE DRAWINGS
[0012] Figure 1 This is a schematic diagram of the structure of the multifunctional office chair of the utility model;
[0013] Figure 2 The utility model is a schematic diagram of the connection structure of the fixed tube, the movable tube and the movable rod of the multifunctional office chair.
[0014] In the figure: lumbar support 1, armrest 2, seat cushion 3, fixed tube 4, movable tube 5, movable rod 6, foot pad 7, hydraulic telescopic rod 8, pulley 9, seat bracket 10, support member 11, first limiting ring 12, second limiting ring 13. DETAILED DESCRIPTION
[0015] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.
[0016] like Figure 1-2 The multifunctional office chair shown includes a lumbar support 1, an armrest 2, a seat cushion 3, a foot pad 7, a hydraulic telescopic rod 8, a pulley 9 and a seat bracket 10. Two fixed tubes 4 are arranged under the seat cushion 3. A movable tube 5 is movably inserted at one end of the fixed tube 4, and a movable rod 6 is movably inserted at one end of the movable tube 5. Both ends of the foot pad 7 are respectively connected to one end of the two movable rods 6 by screws. When adjusting the elongation length of the foot pad 7, it is only necessary to pull the movable tube 5 to slide in the fixed tube 4. After reaching the maximum stroke, the movable rod 6 is pulled to slide in the movable tube 5 to adjust the moving stroke of the foot pad 7, which is convenient for staff with long legs to lie on the seat to rest. The foot pad 7 can support the feet of the staff, avoid compressing the muscles and blood vessels of the calf part, and improve the comfort of the staff.
[0017] The lumbar support 1 is installed on the side of the seat cushion 3 by screws. The lumbar support 1 is an adjustable lumbar support. When the staff needs to rest, they only need to apply external force to the lumbar support 1, and the lumbar support 1 will move in a circular arc on the seat cushion 3, so that the lumbar support 1 rotates to the same horizontal state as the seat cushion 3, making it convenient for the lumbar support 1 to support the waist of the staff.
[0018] Two armrests 2 are mounted on two symmetrical sides of the seat cushion 3 by screws, and the armrests 2 can be used for hand support of the staff.
[0019] The seat bracket 10 is located below the seat cushion 3, the movable end of the hydraulic telescopic rod 8 is installed on the bottom of the seat cushion 3 by screws, the bottom end of the hydraulic telescopic rod 8 is installed on the top of the seat bracket 10 by screws, and a plurality of pulleys 9 are installed on the bottom end of the seat bracket 10 by screws. The pulleys 9 can be used for the sliding of the seat. After the staff stands up, the staff's legs will push the seat back, and there is no need to manually move the seat away, which makes it convenient to separate the seat from the work station.
[0020] A plurality of support members 11 are installed between the outside of the two fixing tubes 4 and the bottom of the seat cushion 3 by means of screws, and the support members 11 improve the stability of the connection between the fixing tubes 4 and the seat cushion 3 .
[0021] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and the specification only describe the principles of the utility model. The utility model may be subject to various changes and improvements without departing from the spirit and scope of the utility model. These changes and improvements fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
