Description

An angle-adjustable library desk

technical field

The utility model relates to a library desk, in particular to an angle-adjustable library desk.

Background technique

For the students of the mechanical department or the art department, drawing is a lesson that they need to go through again and again. Facing the large drawing paper or canvas, it cannot be unfolded on the desks of ordinary classrooms, so they need to go to the library to draw. Although the desks in the library are large enough to hold drawings, the desks are generally horizontal and need to be drawn on the desk, which is not only bad for drawing, but also causes a greater burden on the spine when drawing for a long time.

Utility model content

The applicant has carried out research and improvement aiming at the above-mentioned existing problems, and provides a library desk with an adjustable angle that can support the upper table board and facilitate drawing.

The technical scheme adopted in the utility model is as follows:

An angle-adjustable library desk, the desk includes table legs, a drawer and an upper table top, the drawer is fixed on the table legs, and the left and right sides of the upper end of the drawer are integrally connected with two bent side panels, the The upper table top is arranged between two bent side plates, and the front end of the upper table top is rotatably connected with the two bent side plates through a rotating shaft, the rear end of the upper table top is connected to a driving rod, and the lower end of the driving rod is connected to a driving part. Two fixing clips are arranged on the upper side of the rear end of the upper desktop, and a placement slot is provided on the upper side of the front end of the upper desktop, and a rotatable baffle is arranged in the placement slot, and a control button is arranged on one side of the drawer, and the control button is electrically powered. Even drive parts.

As a further improvement of the above technical solution:

A rolling ball is arranged on the upper end of the driving rod, and a rolling ball seat is arranged on the lower side of the matching upper table top, and the rolling ball cooperates with the rolling ball seat to connect the driving rod and the upper table top.

The driving component is a driving cylinder or a driving oil cylinder.

The beneficial effects of the utility model are as follows: the angle-adjustable library desk can fix the drawing paper on the upper table through the fixing frame, and then the inclination angle of the upper table can be adjusted by driving the cylinder, which is convenient for drawing.

detailed description

Below in conjunction with accompanying drawing, illustrate the specific embodiment of the present utility model.

As shown in Figure 1, the angle-adjustable library desk of the present embodiment includes a table leg 1, a drawer 2 and an upper table top 3, the drawer 2 is fixed on the table leg 1, and the left and right sides of the upper end of the drawer 2 are integrally connected to two One bent side plate 21, the upper desktop 3 is arranged between the two bent side plates 21, and the front end of the upper desktop 3 is rotationally connected with the two bent side plates 21 through a rotating shaft 31, and the rear end of the upper desktop 3 is connected to the driving rod 4 , the upper end of the driving rod 4 is provided with a rolling ball 41, and the lower side of the matching upper desktop 3 is provided with a rolling ball seat 34, and the rolling ball 41 cooperates with the rolling ball seat 34 to connect the driving rod 4 and the upper table 3, and the lower end of the driving rod 4 is connected to the driving cylinder 7, and the upper end of the driving rod 4 is connected to the driving cylinder 7. Two fixed clips 5 are set on the upper side of the desktop 3 rear end, and a placement groove 32 is provided on the upper side of the front end of the upper desktop 3, and a rotatable baffle plate 33 is set in the placement groove 32, and a control button 6 is arranged on one side of the drawer 2, and the control button 6 is electrically powered. Even driving cylinder 7.

When the self-angle-adjustable library desk is in use, the drawing or canvas is fixed on the upper desktop 3 through the fixing frame 5, the control button 6 is pressed, and the upper desktop 3 is pushed up to a suitable position by driving the cylinder 7 and the driving rod 4. The drawing pen or paintbrush can be placed in the placement slot for easy access, and some other items can be placed in the drawer.
