Description

Multi-interface display device

technical field

The invention relates to the technical field of teaching instruments, in particular to a multi-interface display device.

Background technique

The display device is a common teaching tool in teaching. For example, in the art majors of various colleges and universities, many paintings are often hung up for students to explain in class, and multiple paintings are compared and observed. The combination of theory and practice can make the Students quickly grasp the knowledge taught, but when multiple paintings are displayed at the same time due to the lack of display bearing devices, it is impossible to compare them, and it is even more inconvenient to change and describe the paintings. If each painting is displayed on an easel, It also takes up space, and if it is changed frequently, it is easy to damage the drawing paper. If it is an oil painting, it is easy to blur the quality of the picture if it is not completely drained.

Contents of the invention

In view of the technical problems existing in the prior art, the present invention provides a rotatable and reversible multi-interface display device for simultaneous comparative display of multiple paintings.

For realizing above-mentioned technical purpose, the technical scheme that the present invention adopts is as follows:

The multi-interface display device includes a rectangular frame, which is detachably installed above the support frame, the support frame includes a support base and a telescopic rod, one end of the telescopic rod is fixed on the support base, and the other end of the telescopic rod is set There is a 360° swivel joint, and the rectangular frame is flexibly connected to the swivel joint. The rectangular frame is composed of side frames with U-shaped grooves on the other three sides of the upper opening. A sliding shaft that can slide up and down in the side frames on both sides, the sliding shaft is provided with a drawing paper shelf, the upper end of the drawing paper shelf is movably fixed on the upper ends of the two side frames of the rectangular frame, and the rectangular frame The upper ends of the side frames on both sides are provided with movable buckles that can block the sliding shaft.

The multi-interface display device with this design can place multiple pictures on the same easel for comparison at the same time, which saves floor space and makes it easier to understand the comparison of multiple pictures during teaching. Compared with the existing technology, not only the entire rectangular frame can be rotated , the two sides of the drawing paper shelf can also be rotated to make more effective use of materials and space. After a painting is completed, it is not necessary to take it off and replace it in time. It is more convenient to use it by directly reversing the drawing paper shelf, and it also protects the painting when it is not dry. In case of taking it down and damage it.

It is further defined that the movable buckle includes a fixed support fixed on the inner side of the side frame, the lower part of the fixed support is movably connected to the support frame through a pin shaft, the upper part of the fixed support is provided with a handrail buckle, and the handrail buckle is connected to the The pull rod fixed on the support frame, when the armrest buckle is pulled upwards, the pull rod, the support frame and the fixed support can form a tripod to carry the sliding shaft. The outside of the side frame of the rectangular frame is provided with a grab for fixing the armrest buckle. The design of the movable buckle is to fix the sliding shaft to ensure the smooth rotation of the drawing paper shelf. The purpose is to place a few more drawing papers in the case of saving the easel, lift the sliding shaft to the position of the support frame, and then pull the armrest buckle to make the pull rod drive the support The shelf is in a vertical state, and then the armrest buckle is fixed on the hook so that the three form a tripod to support the sliding shaft, so as to ensure that the drawing paper shelf can be turned over smoothly.

It is further defined that the movable buckle is embedded in the inner sides of the side frames on both sides of the rectangular frame, and the inner upper surface of the side frame is flush with the upper surface of the movable buckle. When the sliding shaft moves to the position of the support frame of the movable buckle, the armrest buckle is pulled to fix it.

It is further defined that lighting devices are provided on both sides of the rectangular frame, in order to make the pictorial display clearer.

It is further defined that a buckle is provided on the front side of the bottom side frame of the rectangular frame, and the buckle can be matched with the hook on the front side of the drawing paper shelf. After the drawing paper shelf and the sliding shaft are pulled upward at the same time, the drawing The paper shelf rotates and flips around the sliding axis. This design is to make the drawing paper shelf better fixed and will not turn around along the path.
