Description

Technical Field

[0001] The utility model relates to the field of seats, in particular to a seat which is easy to lift and adjust. Background Art

[0002] Chairs, as one of the indispensable furniture in daily life, are widely used in many fields such as home, office, school, transportation and public places. As people's requirements for quality of life and work efficiency continue to improve, the demand for comfort, convenience and personalization of seats is also increasing. Among them, the lifting and adjustment function of the seat is particularly important. It can meet the needs of people of different heights, and it also helps to improve sitting posture and reduce physical fatigue caused by sitting for a long time.

[0003] The existing seat lifting and adjustment functions are mainly achieved through pneumatic, spiral and other lifting mechanisms. Pneumatic lift chairs are favored by the market for their advantages such as fast lifting speed and easy operation. Their structure mainly includes seats, cylinders, pneumatic rods and bases. The seat is lifted and adjusted by controlling the up and down movement of the piston rod in the cylinder. The spiral lift chair moves the seat in the vertical direction by rotating the spiral rod to achieve the purpose of adjusting the height.

[0004] However, existing seats usually have a height adjustment function, and the height adjustment of the seat will generally drive the armrests of the seat to rise and fall. When the armrests follow the seat to rise and fall, when they are stored under the table, the high height of the armrests can easily lead to a limited storage range of some seats, making it difficult to store the seats under the table. In addition, the footrests on existing seats are simply set and not easy to raise and lower and adjust, and the heights of the armrests and footrests cannot meet the use needs of people of different heights, limiting the applicability of the seats. The spiral lifting mechanism of some seats has poor support for the seats, poor stability during the lifting process, and is prone to shaking or tilting, which provides poor support and comfort for the seats, affecting the use effect.

[0015] The beneficial effects of the utility model are as follows: the seat plate is connected to the lifting rod through the support frame, which enhances the stability of the seat plate and makes the lifting process more stable and smooth, effectively reducing the shaking or jamming phenomenon that may occur during use. The seat plate can be conveniently moved up and down in the lifting sleeve through the lifting rod. When the seat plate is lifted, the columns on both sides of the seat plate are installed with corresponding armrests, so that the armrests are connected with the guide grooves on the columns through the guide tubes, and can be matched with the limiting grooves through the limiting buckles, so that the height of the armrests can adapt to the placement height of the hands of different users, thereby improving the practicality and comfort of the seat. The user can easily adjust it to a suitable height according to his own needs or the needs of the seat storage occasion. The connecting seat on the base is connected to the liftable threaded sleeve through a thread, so that the footrest is connected to the threaded sleeve through the mounting block. The lifting of the threaded sleeve can drive the footrest to be height adjusted, and the lifting of the threaded sleeve is controlled by adjusting the bolt, which provides users with more flexible use options, thereby meeting the needs of users with different heights and improving the comfort of use.
