Description

Technical Field

[0001] This utility model relates to the field of learning tools technology, specifically a device for one-click automatic adjustment of desk and chair height based on myopia prevention and control. Background Technology

[0002] With the fast pace of modern life and the widespread use of electronic products, it has become the norm for children and teenagers to spend long hours studying and entertaining themselves in front of screens. This has not only led to increasingly serious vision problems, especially the sharp rise in myopia rates, but has also had a negative impact on their sitting habits. Maintaining incorrect sitting postures for a long time, such as looking down or bending over, will further aggravate eye fatigue, affect spinal health, and may eventually lead to more serious vision loss and postural problems.

[0003] Currently, there are adjustable tables and chairs on the market designed to accommodate different heights and user needs. By adjusting the height of the tables and chairs, users can maintain a correct sitting posture, thereby reducing the burden on their eyes and spine. However, most traditional adjustable tables and chairs use manual screw rods or lever designs. Users need to exert a lot of force to rotate or push and pull the adjustment device when adjusting the height. This is not only cumbersome to operate, but also particularly inconvenient for people with less strength (such as children and the elderly).

[0004] Therefore, in order to address the above problems, the applicant needs to design a device that automatically adjusts the height of desks and chairs with one click based on myopia prevention and control. Summary of the Invention

[0005] The purpose of this invention is to provide a device for one-click automatic adjustment of table and chair height based on myopia prevention and control, so as to solve the problems mentioned in the background art.

[0007] It also includes: a buffer plate fixedly connected to the lower surface of the table belly, and an electric telescopic rod fixedly installed below the buffer plate. A fixing plate is fixedly installed at the end of the electric telescopic rod away from the buffer plate, and the fixing plate is fixedly connected to the support frame.

[0008] A hollow rod is fixedly connected to the table belly, and a connecting rod is slidably arranged inside the hollow rod. A seat is fixedly arranged at the end of the connecting rod away from the hollow rod. A linkage column is fixedly arranged below the seat, and a fixing frame is slidably arranged on the outside of the linkage column.

[0009] The signal receiver is arranged above the fixed plate and is used to control the starting of the electric telescopic rod.

[0010] Further, the controller is provided with a rising button and a falling button, and the rising button and the falling button are used to control the rising or falling of the electric telescopic rod through the controller and the signal receiver.

[0012] Further, the bottom surface of the support frame is provided with a wear-resistant pad one, the bottom surface of the fixed frame is provided with a wear-resistant pad two, and the bottom ends of the wear-resistant pad one and the wear-resistant pad two are flush.

[0013] Through the above structure design, the wear-resistant pad one and the wear-resistant pad two are used to reduce the friction loss of the support frame and the fixed frame with the ground, so as to improve the service life of the device.

[0014] Further, the top of the fixed plate is fixedly provided with a protective shell, the inside of the protective shell is slidably provided with a sliding block, and the sliding block is fixedly connected with the table belly.

[0015] Through the above structure design, the protective shell and the sliding block are used to protect the electric telescopic rod and improve the safety.

[0016] Further, the bottom of the fixed plate is fixedly provided with a reinforcing rod, and the end of the reinforcing rod away from the fixed plate is fixedly connected with the support frame.

[0017] Through the above structure design, the reinforcing rod is used to support the fixed plate, so as to improve the bearing capacity and stability of the fixed plate.

[0018] Further, the seat is fixedly provided with a connecting frame, and the connecting frame is fixedly provided with a backrest.

[0019] Through the above structure design, the backrest is used to make the seat more comfortable when used.

[0020] Further, the table belly is fixedly provided with a hook, and the hook is used to hang heavy objects.

[0021] Through the above structure design, the hook is used to bear heavy objects, so as to improve the use range of the device and improve the use comfort of the device.

[0022] Compared with the prior art, the one-key automatic height adjusting table and chair device based on myopia prevention has the advantages that the height can be conveniently adjusted, the eyesight is protected, and specific contents are as follows.

[0023] When the one-key automatic height adjusting table and chair device based on myopia prevention is used, the rising button or the descending button is pressed by external force, the controller sends the rising or descending electric signal to the signal receiver, the signal receiver controls the electric telescopic rod to rise or descend after receiving the rising or descending electric signal, the electric telescopic rod rising or descending drives the buffer plate to rise or descend, drives the table belly and the table top plate to rise or descend, at the same time, the table belly moving drives the hollow rod to move, the hollow rod drives the seat to synchronously rise or descend through the connecting rod, the height of the table and the chair is conveniently adjusted, the user's correct sitting posture is helped to maintain, the eyesight is protected, the operation is convenient, and the adjusting efficiency is high.
