Description

Technical Field

[0001] This utility model relates to the field of school supplies technology, and in particular to a student desk and chair with double markings and a standard refinement to 1cm as the unit of precise fitting. Background Technology

[0002] The precise height of student desks and chairs determines whether children will tiptoe, hunch their shoulders, or hunch over the desk while reading and writing. According to GB / T3976-2014 "Functional Dimensions of School Desks and Chairs," a standard reference table is provided for the appropriate height for the desktop, the clearance under the desk, the chair seat height, and the chair seat depth. Currently, the height adjustment components on student desks and chairs on the market only indicate the desktop height or chair seat height, without specifying the appropriate height. Parents and some students need to consult the GB / T 3976-2014 "Functional Dimensions of School Desks and Chairs" reference table to adjust the height correctly. Furthermore, most students are unaware of this reference table and adjust the desks and chairs based on their own feeling, resulting in incorrect reading and writing postures. Incorrect reading and writing postures can easily lead to myopia, strabismus, and spinal misalignment in students.

[0003] The applicant has discovered that the prior art has at least the following technical problems:

[0004] In the existing technology, student desks and chairs only indicate the height of the desktop or the height of the chair, without indicating the appropriate height. Utility Model Content

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0031] In the description of this utility model, it should be noted that, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0032] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0033] This utility model provides a student desk and chair with dual markings, including a lifting component 1 and a dual-marker 2, wherein the dual-marker 2 is engraved on the lifting component 1; the dual-marker 2 includes desktop height data 21 or chair height data 22, height data 23, and scale lines 24, the desktop height data 21 and height data 23 are respectively located on both sides of the scale line 24, and one scale line 24 corresponds to a height value of desktop height data 21 and a height value of the corresponding height data 23; or the chair height data 22 and height data 23 are respectively located on both sides of the scale line 24, and one scale line 24 corresponds to a height value of chair height data 22 and a height value of the corresponding height data 23. This utility model provides a student desk and chair with dual markings. The outer wall of the lifting component 1 on the student desk is engraved with a dual-marking ruler 2, with the desktop height data 21 and the height data 23 corresponding one-to-one through the scale lines 24. The outer wall of the lifting component 1 on the student chair is also engraved with a dual-marking ruler 2, with the chair height data 22 and the height data 23 corresponding one-to-one through the scale lines 24. Therefore, when adjusting the height of the student desk and chair, students only need to check the corresponding position of the desktop height data 21 or chair height data 22 and height data 23 on the lifting component 1, so that they can adjust the height of the student desk and chair according to their own height without having to look up the reference table GB / T 3976-2014 "Functional Dimensions of School Desks and Chairs". This solves the technical problem in the prior art where student desks and chairs only have the desktop height or chair height dimensions marked, but do not have the corresponding height dimensions marked.

[0034] The difference between the two height values ​​in the desktop height data 21 corresponding to two adjacent scale lines 24 is 1cm; or the difference between the two height values ​​in the chair height data 22 corresponding to two adjacent scale lines 24 is 1cm. The dual-scale ruler 2 accurately adapts to the user's height with a 1cm desktop or chair height. This allows the user to more accurately adapt to their own height, ensuring that their feet are firmly planted, thighs are parallel to the ground, back is supported, the desktop is at their abdomen, shoulders are not hunched, forearms are naturally resting on the edge of the table, and the body is relaxed. The eyes are one foot away from the desktop, achieving the 33cm golden viewing distance, allowing the eyes to maintain their physiological state and protecting them from myopia (when the viewing distance is less than one foot, the ciliary muscle contracts, causing the lens to become more convex, increasing refractive power and causing accommodative lag, leading to axial elongation, the core cause of myopia), reducing the occurrence and development of myopia, while also reducing spinal curvature and distracting learning efficiency and concentration. This utility model first refers to GB / T 3976-2014 "Functional Dimensions of School Desks and Chairs" to calculate the value of the required desktop height per centimeter for a height of 105 cm to 180 cm, and the value of the required chair height per centimeter.

[0035] As an optional implementation, the lifting component 1 is a manual lifting structure, and the user needs to manually operate the lifting component 1 to raise or lower it.

[0036] As an optional implementation, the lifting assembly 1 is a pneumatic lifting structure or an electric lifting structure, and the lifting of the lifting assembly 1 can be controlled by a switch.

[0037] As an optional implementation, a display screen and an operation panel are also included. The display screen and the operation panel are electrically connected and are both installed on the student desk or chair. The operation panel is electrically connected to the drive device on the lifting assembly 1. The display screen is used to display the user's height value and the corresponding desktop height or chair height value. The display screen is used to display accurate data that matches the user's reading and writing posture, that is, the user's height value and the corresponding desktop height or chair height value. When the user raises or lowers the desk and chair using the up or down keys on the operation panel, the current desktop height or chair height is displayed, and the height that matches the sitting posture is also displayed. Alternatively, the user can input a height value, and the corresponding desktop height value or chair height value will be displayed on the display screen, while the lifting assembly 1 will be adjusted to the displayed height. Or, the user can input a desktop height value or chair height value on the operation panel, and the corresponding height value will be displayed on the display screen, while the lifting assembly 1 will be adjusted to the displayed height.

[0038] The control panel features up and down buttons and shortcut keys. Pressing the up button increases the value displayed on the screen, while pressing the down button decreases the value. The shortcut keys are pre-set values ​​that are directly displayed on the screen when pressed. Alternatively, the control panel can have a touch screen, allowing users to input numbers by handwriting or touching the corresponding area to output values. Another option is a control panel with 10 numeric keys (0-9) and a decimal point key, allowing users to input values ​​by pressing the keys.

[0039] As an optional implementation, a bidirectional scale 2 is engraved on the outer wall of the inner rod 11 on the lifting assembly 1, and the inner rod 11 extends into the outer sleeve 12 of the lifting assembly 1 and is slidably connected to the outer sleeve 12.
