Description

Technical Field

[0001] The utility model belongs to the field of mechanical education desks, in particular to a desk with an adjustable tabletop angle. Background Art

[0002] Art education is a kind of education that uses education as a means to impart certain art knowledge and skills to students, develop and spread art culture, cultivate students' moral sentiment and aesthetic ability, and develop intelligence and creativity. Art desks are tables specially designed for art teaching and creation, providing teachers and students with a comfortable and convenient learning place;

[0003] Since students need to sit or stand for a long time during study, if the angle of the table is not suitable for the students, they will need to adopt incorrect postures such as lowering their heads or stretching their bodies forward for a long time to complete the learning process. This will cause stiffness and pain in the neck and shoulders. This posture may cause problems such as cervical spondylosis or periarthritis of the shoulder. Maintaining a bent or unnatural sitting posture for a long time will bring pressure and burden to the waist and back, causing low back pain. Incorrect sitting posture will also increase the pressure on the spine and affect the stability and health of the spine.

[0004] Therefore, we hope to design a desk with an adjustable tabletop angle to solve this problem. Utility Model Content

The connecting rod 65 is movably connected to the horizontal plate 1. By setting the angle adjustment component 6, the angle of the table board 3 can be adjusted.

[0027] The height adjustment component 4 includes a connecting leg 41, a ring 42, an insert rod 43, an elastic component 44, a connecting tube 45 and a connecting block 46. The connecting leg 41 is fixedly connected to the lower side of the cross plate 1, and the connecting leg 41 is slidably sleeved in the interior of the support frame 5. A plurality of grooves are opened on the right side of the connecting leg 41, and the insert rod 43 is engaged with the grooves. The insert rod 43 is slidably sleeved in the interior of the connecting leg 41, and the insert rod 43 is slidably sleeved in the interior of the support frame 5. An elastic component 44 is provided on the outside of the insert rod 43, and a connecting tube 45 is provided on the outside of the elastic component 44. A connecting block 46 is fixedly connected to the right side of the insert rod 43. By setting the height adjustment component 4, the height of the table top 3 can be adjusted.

During the displacement of the moving block 622, the support rods 64 fixedly connected to both sides thereof are driven to move, and the support rods 64 drive the connecting rods 65 hinged thereto to move. When the support rods 64 move forward, the connecting rods 65 lift up the table top 3. When the support rods 64 move backward, the table top 3 loses its upward force, and as the connecting rods 65 move downward, the angle adjustment is achieved.

[0033] See also Figure 1-Figure 3 , as the second embodiment of the present utility model: based on the description in the above embodiment, further, when it is necessary to adjust the height of the table board 3, the two connecting blocks 46 are pulled in the same direction at the same time, and the connecting block 46 drives the plug rod 43 fixedly connected thereto to move, and the plug rod 43 drives the slider 441 fixedly sleeved therewith to move, and the slider 441 moves while squeezing the spring 442. During the movement of the plug rod 43, the plug rod 43 is separated from the connecting leg 41, and a rubber ring 42 is fixedly connected to the upper side of the support frame 5, which is used to enhance the friction between the connecting leg 41 and the support frame 5 to prevent the horizontal board 1 from falling suddenly, and then the height of the table board 3 is adjusted by pressing down or lifting up the horizontal board 1. When the height of the table board 3 is adjusted to a suitable position, the connecting block 46 is released, and under the elastic force of the spring 442, the spring 442 is reset to drive the slider 441 to move, and the slider 441 drives the plug rod 43 to move and insert into another groove of the connecting leg 41.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
