LCD projection device for reducing external dust erosion based on music teaching

Abstract

The invention discloses an LCD projection device for reducing external dust erosion based on music teaching. The LCD projection device comprises a fixed top seat, the fixed top seat is designed to be of a circular disc-shaped structure; a fixed frame is rotationally mounted on the bottom side of the fixed top seat; a projection device placement box is rotationally mounted on the lower side of the fixing frame; and a mounting frame is arranged on the inner side of the projection device placement box, and an LCD projection device is placed and mounted on the mounting frame. According to the LCD projection device capable of reducing external dust erosion, heat conduction bags are fixedly arranged on the inner walls of the upper side and the lower side of a projection device placement box, the heat conduction bags are made of soft materials, the heat conduction bags are communicated with cooling fins, and the inner sides of the heat conduction bags are also filled with heat conduction and cooling liquid; the design of the heat conduction bag is beneficial to better and closer contact with the upper wall and the lower wall of the LCD projection device, so that heat on the inner side of the LCD projection device is better absorbed and dissipated through the cooling fins, and the heat dissipation rate and the heat dissipation effect of the LCD projection device are effectively improved.

Description

technical field [0001] The invention relates to the technical field of music teaching auxiliary equipment, in particular to an LCD projection device for reducing external dust erosion based on music teaching. Background technique [0002] In today's pursuit of high efficiency and fast-paced modern office, projectors can be seen everywhere as new office equipment users. The projector can not only be used in temporary meetings, technical lectures, network centers, command and monitoring centers, but also can be connected with computers, workstations, etc., or connected with video recorders, TV sets, DVD players, and physical exhibition stands, etc. It can be said that it is a kind of Widely used large-screen imaging equipment; among them, LCD projection devices are often used in teaching. [0003] After patent retrieval, the existing patent number is CN 102636945 B, a projector dustproof device, including a first elastic fastening cover, a second elastic fastening cover, an e...

Problems solved by technology

[0007] The object of the present invention is to provide a kind of LCD projection device based on music teaching to reduce external dust erosion, to solve the problem that the structural design proposed in the above background technology is relatively traditional, resulting in poor dustproof effect, and the existing methods of improving dustproof effect The method is to seal the outer side with a dust-proof box. Although this method improves the dust-proof effect, it reduces the heat dissipation performance, thereby affecting the use effect of the projection device and reducing the service life of the projection device. If the cooling fan is added, it will increase. The risk of dust entering, the place where the cooling fan is added will absorb a large amount of dust, which increases the risk of dust eroding the projection device, and dust obstruction will also affect the heat dissipation effect, and the existing projection devices are mostly installed on the roof wall of the house , so that the use of adjustment and maintenance is extremely inconvenient
