Description

Technical Field

[0001] The utility model relates to the technical field of student tables and chairs, in particular to a student table and chair with protection and correction functions. Background Art

[0002] At present, many students have the habit of bad sitting posture. In the long run, it will not only cause different degrees of damage to students' bodies, but also make students' eyesight decline more easily. Continuous development can turn into irreversible true myopia. Therefore, it is very important to correct students' bad sitting posture and protect their eyesight.

[0003] However, existing student desks and chairs are generally just ordinary desks and chairs. Although both can be adjusted in height according to students' needs, they do not have the function of correcting students' bad sitting postures and protecting students' eyesight; and the chairs and stools can only be adjusted at a few fixed heights, and the adjustment accuracy is low. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the above technical difficulties and provide a student desk and chair with a protective and corrective function, which can effectively correct students' bad sitting posture and protect students' eyesight when in use, and the height adjustment accuracy of the chair and stool is higher.

[0005] In order to solve the above technical problems, the technical solution provided by the utility model is:

[0006] A student desk and chair with protection and correction functions, comprising a desktop panel and a chair panel, a storage box is fixed on the lower side of the desktop panel, a backrest panel is fixed on the chair panel, and further comprising:

[0007] A crossbeam and an inverted T-shaped table leg; the table legs are provided in a pair in mirror image on the left and right sides, and the tops are detachably mounted on the left and right sides of the storage box, and the two ends of the crossbeam are detachably connected to the middle of the two table legs respectively;

[0008] The telescopic chair stool legs are mirror-imaged and arranged in a pair on the left and right sides; the telescopic chair stool legs include an inner thread tube, an outer thread tube, a handle screw and a support foot; the top of the inner thread tube is fixed to the lower side of the chair panel, and the inner thread is matched with the outer thread tube, the bottom end of the outer thread tube passes through to the outside of the inner thread tube, and the support foot is fixed to the bottom end, and a long strip-shaped limiting through hole is reserved on the side wall of the outer thread tube, and the handle screw passes through and is threadedly connected to the outer wall of the inner thread tube, and is just inserted into the limiting through hole;

[0009] A chest and abdomen support plate and a supporting structure; the chest and abdomen support plate is connected to the desktop panel via the supporting structure, and the distance between the chest and abdomen support plate and the desktop panel is adjustable.

[0010] As an improvement, a threaded sleeve is integrally formed on the outer wall of the inner thread tube. After the handle screw is threaded into the threaded sleeve, an anti-slip washer is sandwiched between the handle and the end surface of the threaded sleeve. In this way, the inner thread tube and the outer thread tube can be more firmly fixed together by the handle screw.

[0011] As an improvement, the support structure includes a movable rod, a limiting sleeve and a hand screw; the back of the chest and abdomen support plate is fixedly connected with a movable rod, and a limiting sleeve fixed to the lower side of the desktop panel is movably sleeved on the movable rod, and the movable rod is fixed to the inner side of the limiting sleeve by a hand screw. It is convenient to adjust the distance between the chest and abdomen support plate and the desktop panel.

[0012] The advantages of the utility model compared with the prior art are:

[0013] 1. When the present invention is in use, the distance between the student and the desktop can be limited through the design of the chest and abdomen support plate and the supporting structure, thereby effectively correcting the student's bad sitting posture and protecting the student's eyesight.

[0014] 2. When the new model is in use, the design of the retractable chair legs makes the height adjustment accuracy of the chair panel higher and can better meet the height adjustment needs of students.

[0015] 3. The desk part and the seat part of the new model are both assembled structures, and can be loaded and transported more conveniently after being disassembled. BRIEF DESCRIPTION OF THE DRAWINGS
