Description

Technical Field

[0001] This utility model relates to the field of ruler technology, and is a height matching ruler for school desks and chairs. Background Technology

[0002] A height-matching desk and chair ruler is a tool used to determine the height of student desks and chairs to ensure that the height of the desks and chairs matches the student's height, thereby promoting good posture and preventing health problems such as myopia and spinal curvature. The height-matching desk and chair ruler is usually a height chart that can be pasted on the wall. It uses corresponding colors to mark the appropriate desk and chair models for children within a certain height range, which makes it easy for teachers, parents and children to determine the appropriate desk and chair height based on their height.

[0003] However, in the current technology, the ordinary ruler is used to measure the student's height, and then the appropriate height of the desk and chair can be seen on the diagram. But it is not intuitive enough. If you don't use a ruler to measure the desk and chair, you still don't know if it is suitable for you. Utility Model Content

[0004] This invention addresses the problem that while ordinary rulers measure student height and can show the appropriate desk and chair height on a diagram, this is not intuitive enough. Without measuring the desk and chair, it is still difficult to determine whether it is suitable for the student. Therefore, this invention provides a height-matching desk and chair ruler.

[0005] This utility model solves the above-mentioned technical problems through the following technical solutions:

[0006] This utility model provides a height matching ruler for desks and chairs, which includes:

[0038] like Figure 1-6 As shown, the height-matching scale for school desks and chairs includes:

[0039] A scale 1, with a lower mounting component 2 installed at its bottom end;

[0040] Upper mounting component 3 is mounted on the top of the scale 1, and the upper mounting component 3 and the lower mounting component 2 are used to fix the scale 1.

[0041] The calibration rod 4, the top of which is engaged with the retaining clip 5 mounted on the side surface of the scale 1;

[0042] The calibration component 7 is mounted on the surface of the calibration rod 4 and is used to determine the height of the table and chair corresponding to the height of the person.

[0043] The scale ruler 1 is securely installed on the wall using the upper mounting component 3 and the lower mounting component 2, ensuring its stable placement and facilitating orderly measurement by students. This avoids the need to frequently pick up and put down the scale ruler 1, saving time. The scale ruler 1 is used to measure students' height, and the appropriate desk and chair height is determined based on the student's height. The calibration component 7 is adjusted along the calibration rod 4 to easily move the calibration component 7 to the corresponding desk and chair height position. The calibration rod 4 can then be removed to compare with the student's own desk and chair; if the position is approximately the right height, it is suitable for the student's judgment.

[0044] The scale 1 includes a scale plate 11, a height area 12, and a height-corresponding seat height area 13. The front surface of the scale plate 11 is provided with scale lines, the surface of the scale plate 11 is provided with the height area 12, and the bottom side of the height area 12 is provided with a height-corresponding seat height area provided on the front surface of the scale plate 11. The height area 12 and the height-corresponding seat height area 13 can be set with corresponding colors.

[0045] In the height zone 12, first stand in front of the ruler to determine your height. Observe the color corresponding to height zone 12. Then, go to the corresponding color block in the chair height zone 13 below to determine the height of the table and chair, specifically where the table and chair reach your legs and hips.

[0046] The lower mounting assembly 2 includes a lower fixing seat 21, a lower mounting seat 22, and a lower mounting bolt 23. The lower fixing seat 21 is fixedly connected to the bottom surface of the scale plate 11, and the lower mounting seat 22 is fixedly connected to the side surface of the lower fixing seat 21. The lower mounting bolt 23 is threaded through the surface of the lower mounting seat 22.

[0047] The lower mounting base 22 is fixed by the lower mounting bolt 23, thereby fixing the lower mounting base 21 to the wall.

[0048] The number of lower mounting seats 22 is two, and the two lower mounting seats 22 are symmetrically distributed about the lower fixing seat 21.

[0049] The upper mounting assembly 3 includes an upper fixing seat 31, an upper mounting seat 32, and an upper mounting bolt 33. The upper fixing seat 31 is fixedly connected to the top surface of the scale plate 11, the upper mounting seat 32 is fixedly connected to the side surface of the upper fixing seat 31, and the upper mounting bolt 33 is threadedly connected to the surface of the upper mounting seat 32.

[0050] Rotate the upper mounting bolt 33, which passes through the upper mounting base 32. The upper mounting base 32 is fixed by the upper mounting bolt 33, and the scale 1 is kept stable under the action of the lower mounting component 2.

[0051] The number of upper mounting seats 32 is two, and the two upper mounting seats 32 are symmetrically distributed about the upper fixed seat 31.

[0052] The bottom end of the calibration rod 4 is engaged with the slot 24 opened on the top side surface of the lower fixed base 21. A handle 6 is fixedly connected to the front side of the top end of the calibration rod 4. The top end of the calibration rod 4 is engaged with the housing 5, which has a U-shaped structure in the top view.

[0053] The calibration assembly 7 includes a sliding frame 71, a fixed rod 72, a pull frame 73, an elastic spring 74, and a pointer plate 75. The sliding frame 71 is slidably sleeved on the surface of the calibration rod 4. The fixed rod 72 is slidably connected to the right side surface of the sliding frame 71. The pull frame 73 is fixedly connected to the right end of the fixed rod 72. The elastic spring 74 is fixedly installed on the side surface of the pull frame 73. The pointer plate 75 is fixedly connected to the left side of the sliding frame 71.

[0054] In student height measurement, based on the student's height, the pull frame 73 causes the fixed rod 72 to detach from the surface of the calibration rod 4, moving the sliding frame 71. The sliding frame 71 causes the fixed pointer plate 75 to move, indicating the corresponding scale line. The pull frame 73 is then released, and under the action of the elastic spring 74, the fixed rod 72 and the calibration rod 4 are brought into contact, thus fixing the sliding frame 71. The calibration rod 4 is then removed, making it easy to compare with one's own desk and chair. If the position is approximately the right height, it is suitable for the student to judge and use.

[0055] There are two elastic springs 74, which are symmetrically distributed about the fixing rod 72. The fixing rod 72 passes through the side surface of the sliding frame 71, and the pull frame 73 is elastically connected to the sliding frame 71 through the elastic springs 74.

[0056] The pointer plate 75 is disposed on the front side of the scale plate 11, and the pointer plate 75 slides and fits against the scale plate 11.

[0057] The circuits, electronic components, and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this application does not involve any improvement to the software and methods.
