Description

Technical Field

[0001] The utility model relates to the technical field of teaching tools, and in particular to an interactive projection touch-screen all-in-one machine. Background Art

[0002] The teaching touch all-in-one machine is developed on the basis of conventional electronic teaching and computer equipment. It has the functions of teaching, academic reports, conferences, comprehensive discussions, demonstration exchanges, remote teaching, remote marking, remote classes, remote question setting, remote conferences, etc.; through the touch function, it can better meet the comprehensive requirements of academic reports, conferences, academic exchanges, multimedia teaching, on-site teaching and distance education, and has an intelligent management system and good audio and video effects; it can also meet the requirements of comprehensive demonstration, discussion, and live broadcast through various resources such as slides, projection films, multimedia courseware, videotapes, DVD / SVCD / VCD, physical materials, etc., with good visual effects, improving the school's strength and image.

[0003] The above device still has the following deficiencies in practical application:

[0004] Because the device is exposed to the air for a long time and the electronic parts such as the projection touch screen are relatively fragile and cannot be protected during non-working hours, it will be damaged under the action of certain external forces, which increases the possibility of damage to the device. Based on this, an interactive projection touch screen all-in-one machine is proposed. Utility Model Content

[0005] The purpose of the utility model is to provide an interactive projection touch screen all-in-one machine to solve the problems raised in the above background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] An interactive projection touch screen all-in-one machine includes a main body box, a lifting motor is arranged inside the main body box, the output end of the lifting motor is connected to a power gear, the side of the power gear is rotatably connected to a left connecting gear and a right connecting gear, a left threaded column is installed on the top of the left connecting gear, and a right threaded column is installed on the top of the right connecting gear, and the right threaded column is connected to the lifting platform through threads.

[0008] Preferably, the left connecting gear and the right connecting gear are symmetrically arranged on both sides of the power gear, and are rotationally connected to the power gear arranged in the middle.

[0009] Preferably, bearings are provided at the bottom ends of the left connecting gear and the right connecting gear, and the left threaded column and the right threaded column both penetrate the lifting platform.

[0010] Preferably, two holes are provided at the top of the lifting platform, the diameters of the holes match the left threaded column and the right threaded column, and the shape of the holes is designed to be wide at the top and narrow at the bottom.

[0011] Preferably, a rotating disk is provided at the top of the lifting platform, a connecting column is installed at the top of the rotating disk, a connecting plate is provided on the side of the connecting column, a projection screen is connected to the top of the connecting plate, and a handle is installed at the top of the rotating disk.

[0012] Preferably, a groove is provided at the top of the lifting platform, the size of the groove matches the rotating disk, and connecting plates are symmetrically provided on both sides of the connecting column.

[0013] Preferably, a connecting shaft is provided inside the connecting column, and both ends of the connecting shaft are respectively connected to the connecting plate.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. By turning on the lifting motor, the lifting motor drives the power gear at the output end to rotate, and the power gear drives the left connecting gear and the right connecting gear on both sides to rotate synchronously, so the left threaded column and the right threaded column respectively connected to the left connecting gear and the right connecting gear will also rotate synchronously. The lifting platform penetrated by the left threaded column and the right threaded column cannot rotate synchronously due to the limitation of the main box, so the lifting platform will move up and down vertically along the thread extension direction of the right threaded column. When the device is not in working time, the lifting platform can be moved downward to make the projection screen at the top enter the main box and store the projection screen, thereby protecting the projection screen and its related electronic components and reducing the possibility of damage to the projection screen by the outside.

[0016] 2. The rotating disk can be rotated in situ by the rotating shaft arranged at the bottom of the rotating disk to adjust the horizontal display angle of the projection screen. The connecting plate is connected to the connecting shaft arranged inside the connecting column to adjust the vertical display angle of the projection screen, which increases the flexibility of the device, can display more angles, and improves the viewing effect of users.
