Multifunctional learning seat

Abstract

A multifunctional learning seat comprises a carriage, a backrest plate, a seat plate component, a pneumatic bar, and a connecting sleeve. The seat plate component comprises a top plate, a backrest plate support, and a lifting regulating lever, wherein one end of the backrest plate support is fixedly connected to the top plate. A resilient tube is disposed at the other end of the backrest plate support and fixedly connected with the backrest plate. The top end of the pneumatic bar is connected with the lifting adjusting lever. The bottom end of the pneumatic bar is connected with the carriage through the connecting sleeve. The lifting adjusting lever is fixed at the bottom of the bottom plate through a screw. The carriage is provided with tube legs which are provided with castors or suckers. A return spring is disposed inside the resilient tube. The height of the seat is optionally adjusted through the pneumatic bar and the adjusting lever, a chair meeting the needs of students for height and posture is provided for students, the seat can be applied to keep correct reading-writing postures during learning, spinal column deformity and myopia are prevented, and the design of the carriage with the tube legs allows the structure of the seat to be more solid and stable.

Description

technical field [0001] The invention relates to a rotating and lifting learning seat, in particular to a multifunctional learning seat. Background technique [0002] Existing school chairs for students generally have a fixed height from the chair surface to the ground. Since the height of students changes greatly during the study period, if the distance between the chair surface and the desk surface and the chair surface to the ground cannot be adjusted in time, the use of time is not in line with hygiene. Standard desks and chairs will cause the feet to not be flat on the ground. The gravity of the calf will compress the blood vessels and nerves at the back of the thigh, and the blood circulation will be poor. Sitting on the front of the chair, bearing weight on both upper limbs; the height difference between desks and chairs makes students’ eyes too close when reading and writing; when writing, the shoulders are shrugged or one arm can only be placed on the table, resultin...

[0002] Existing school chairs for students generally have a fixed height from the chair surface to the ground. Since the height of students changes greatly during the study period, if the distance between the chair surface and the desk surface and the chair surface to the ground cannot be adjusted in time, the use of time is not in line with hygiene. Standard desks and chairs will cause the feet to not be flat on the ground. The gravity of the calf will compress the blood vessels and nerves at the back of the thigh, and the blood circulation will be poor. Sitting on the front of the chair, bearing weight on both upper limbs; the height difference between desks and chairs makes students’ eyes too close when reading and writing; when writing, the shoulders are shrugged or one arm can only be placed on the table, resulting in scoliosis; the height difference between desks and chairs is too small , when the head and trunk are bent forward, the weight of the upper body is supported by the upper limbs and the upper body is placed on the table to form a kyphosis, which induces cervical spondylosis and myopia
