Description

Technical Field

[0001] The present application relates to the technical field of desk and chair structures, and in particular to a posture-correcting classroom chair. Background Art

[0002] Desks and chairs, also known as desks and chairs in English, are the desks and chairs used by students in class. They are a type of desks and chairs, also called student desks and chairs, school desks and chairs. Desks and chairs can be divided according to age, material, and function. At present, the production of desks and chairs is replacing wood, steel, copper, and aluminum with plastic, which is an inevitable trend of technological advancement and the only way for the development of my country's manufacturing industry in the future. Desks and chairs are no exception. Moreover, desks and chairs can not only adjust the height, but also have a kind of connected desks and chairs, which are composed of adjustable-height desks, chairs, and adjustable-distance connecting plates. It solves the problem that the existing desks and chairs for primary and secondary school students cannot adjust the height of the table, the height of the chair, and the distance between the desks and chairs. It is suitable for students of all ages and shapes, and can be adjusted to a state that fully meets the hygiene standards of desks and chairs according to the individual situation of each student.

[0003] Currently, the desks and chairs used in schools can be flexibly adjusted to meet the needs of students, but there are still drawbacks in the structure of desks and chairs and their use. Most desks and chairs are flat and not ergonomic. Students will feel tired when using them. Moreover, because the desks and chairs are two separate individuals, students cannot stably adjust the comfortable position between the desks and chairs. Utility Model Content

[0004] One of the purposes of the present application is to provide a posture-correcting classroom chair.

[0005] In order to achieve the above purpose, the technical solution adopted in the present application is: a posture-correcting classroom chair, including a table top, a storage opening is provided on one end surface of the table top, a table tube is provided on the other end surface of the table top, a placement table is detachably connected to the lower outer portion of the table tube, the placement table is L-shaped as a whole, table legs are detachably connected to the table tops on both sides of the table tube, racks are provided on the inner end surfaces of the table legs, and the racks are parallel to the table legs.

[0006] Preferably, a groove is provided on the inner end surface of the table leg, the groove is the same shape as the rack, the rack is clamped in the corresponding groove, and a sliding rod is provided on one end of the rack.

[0007] Preferably, the slide bar is slidably connected to the table leg, the slide bar is horizontally arranged on the table leg, a baffle is arranged on one end of the slide bar, the baffle is arranged in a circular shape, and the diameter of the baffle is greater than the diameter of the slide bar.

[0008] Preferably, a return spring is sleeved on the slide rod, one end of the return spring is connected to the groove, the other end of the return spring is connected to the rack, and the return spring is located between the groove and the rack.

[0011] Compared with the prior art, the beneficial effects of this application are:

[0012] The present invention provides a storage opening on the table top, which can be used to store pens to prevent them from falling and being lost. A placing table is installed on the table tube of the table top, on which a water cup can be placed, and the water cup can be placed horizontally to make the placement of the water cup more stable. Racks are provided on the legs of the table top, and the racks can be connected to the fixed seats of the chair legs. When the chair legs are connected through the racks of the fixed seat legs, the positions between them can be adjusted, so that they can maintain a comfortable position after adjustment, thereby preventing the table and chair from being separated after adjustment, making it more comfortable for students to use.

[0013] In this solution, a fixed seat is arranged on the chair leg, and the fixed seat can be connected to the rack. The rack can be extended and retracted in the vertical groove of the fixed seat. During the extension and retraction process, the position between the table and the chair can be adjusted. The second gear and the first gear are arranged on the fixed seat. When the rack moves, it can drive the second gear to rotate. When the second gear rotates, the first gear will also rotate. After the adjustment is completed, the clamping head is inserted into the first gear, so that the first gear and the second gear will not rotate, and the rack will no longer move, so that the position after adjustment will not change, which is more convenient to use.
