Regulating mechanism realizing continuous and wide-range adjustment on dip angle of table board and learning table

Abstract

The invention provides a regulating mechanism realizing continuous and wide-range adjustment on the dip angle of a table board and a learning table using the regulating mechanism. The regulating mechanism comprises a connecting part, a trapezoidal screw, a first rolling bearing with a box, a second rolling bearing with a box, a trapezoidal nut slider and a hand crank, wherein the upper end of theconnecting part is hinged to the back side of the table board, and the lower end of the connecting part is hinged to the trapezoidal nut slider; a first end of the trapezoidal screw and the first rolling bearing with the box are in transition fit, and the part, close to the second end, of the trapezoidal screw and the second rolling bearing with the box are in transition fit; the first rolling bearing with the box and the second rolling bearing with the box are fixedly connected with a table board fixing rack; and the hand crank is arranged in the second end of the trapezoidal screw. For the regulating mechanism and the learning table, the trapezoidal screw and the trapezoidal nut slider are in screwing match, a self-locking effect is achieved, the self-locking is steady and reliable, theadditional locking and unlocking components and parts are not needed, the learning table with the design is simple in structure, and easy and labor-saving to operate, more important, the dip angle adjustment is smooth and steady, as well as continuous, and the range is large. The adjustment on the dip angle of the table board can reach 90 degrees, and continuous adjustment within 0-90 degrees canbe realized.

Description

technical field [0001] The invention relates to an adjustment mechanism capable of continuously adjusting the inclination angle of a desktop board in a large range and a study table using the adjustment mechanism. Background technique [0002] At present, the inclination adjustment range of most of the learning desks is small, only 0-30°, and very few of them can be adjusted to a large extent, and can only be adjusted intermittently. The adjustment method is complicated and inconvenient to operate. [0003] With the advancement of science and technology, children's learning needs are also expanding rapidly. The learning table is not only a simple need for reading and writing, but is expanding to many aspects of learning and life; including painting, etc. -30° is difficult to meet children's learning needs; moreover, the tabletop inclination adjustment method is complicated, requiring multiple actions at the same time with one hand, not only pulling the top of the tabletop wi...

[0002] At present, the inclination adjustment range of most of the learning desks is small, only 0-30°, and very few parts can be adjusted to a large extent, and can only be adjusted intermittently. The adjustment method is complicated and inconvenient to operate.

[0003] With the advancement of science and technology, children's learning needs are also expanding rapidly. The learning table is not only a simple need for reading and writing, but is expanding to many aspects of learning and life; including painting, etc. -30° is difficult to meet children's learning needs; moreover, the tabletop inclination adjustment method is complicated, requiring multiple actions at the same time with one hand, not only pulling the top of the tabletop with one hand, but also pressing the button or handle with the same hand while pulling the tabletop with one hand or the left hand pulls the top of the desktop, and the right hand simultaneously presses the button switch at the bottom of the desktop to unlock or lock. These desktop tilt adjustment actions are for growing users (children). The operation is extremely inconvenient, time-consuming and labor-intensive, and has potential safety hazards, which does not meet the requirements of ergonomics at all.
