[0020] Compared with the related art, the dustproof conference projector provided by the utility model has the following beneficial effects:

[0021] The utility model provides a dustproof conference projector. When the existing projector body is not in use, it is just randomly placed aside. The dust in the air is easy to adhere to the projector body for a long time. When the dust adheres to the lens, it affects the use of the projector body. The dust enters the projector body from the heat dissipation port and easily causes dust accumulation in the internal components. Therefore, when the projector body needs to be protected from dust, two positioning holes on one side of the arch plate are aligned with two positioning rods on one side of the projector body and inserted for positioning. When the arch plate is placed in place, the screw rods on the inner walls of the two fixing plates are driven to rotate by rotating the rotating rod, and the movement of the two connecting plates is driven by the rotation of the screw rod. Because the arc surface of the screw rod is provided with two reverse threads, the two connecting plates can move closer to or away from each other, and at the same time, the two connecting plates move on the arc surface of the limiting rod. The limiting rod can prevent the two connecting plates from deflecting during the movement, and the movement of the two connecting plates away from each other drives the two fixing rods to move away from each other. The two fixing rods are respectively inserted into the two fixing grooves on the inner wall of the groove to limit and fix the arched plate when the projector body is not in use, the first dustproof cloth rolled up on the connecting rod is moved and unfolded to cover the projector body, so that the gravity rod on the first dustproof cloth is hung on the other side of the projector body. After the dust cloth is laid, the two second dust cloths are turned over and laid on the front and back sides of the projector body respectively, so that the projector body is protected from dust by the first dust cloth and the second dust cloth. When the projector body needs to be used, the two second dust cloths are turned over and laid on the first dust cloth, and then the connecting rod is driven to rotate by rotating the turntable. The arc surface of the turntable is fixed with an anti-slip sleeve, which can increase the friction between the hand of the person and the arc surface of the turntable, so that the person can rotate the turntable more stably. The material of the turntable is titanium alloy. The surface of the titanium alloy turntable is relatively hard. Even after long-term use, the titanium alloy turntable will not be deformed, and the service life is relatively long. The first dustproof cloth and the second dustproof cloth are rolled up by rotating the connecting rod. After the rolling is completed, the screw on the inner wall of the connecting plate is rotated to insert it between the gear teeth for fixing. A guide block is fixed to one end of the screw. Because the guide block is conical, it is convenient for the screw to be quickly and accurately inserted between the gear teeth on the gear. When the first dustproof cloth and the second dustproof cloth need to be cleaned, the two fixing rods are driven to move closer to each other and disengage from the fixing groove to release the fixation by rotating the rotating rod in the opposite direction. Then the arch plate is removed to clean the first dustproof cloth and the second dustproof cloth. By setting the adjustment structure, the effect of conveniently protecting the projector body from dust when it is not in use is achieved. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The working principle of a dustproof conference projector provided by the utility model is as follows: when the existing projector body 1 is not in use, it is just placed aside at random. The dust in the air is easy to adhere to the projector body 1 for a long time. When the dust adheres to the lens, it affects the use of the projector body 1. When the dust enters the interior of the projector body 1 from the heat dissipation port, it is easy to cause dust accumulation in the internal components. Therefore, when the projector body 1 needs to be protected from dust, the two positioning holes 217 on one side of the arch plate 201 are aligned with the two positioning rods 216 on the side of the projector body 1 and inserted for positioning. When the arch plate 201 is placed in place, the screw rods 212 on the inner walls of the two fixing plates 211 are driven to rotate by rotating the rotating rod 213, and the screw rods 213 are used to rotate the screw rods 213. The rotation of 212 drives the movement of the two connecting plates 214. Because the arc surface of the screw rod 212 is provided with two reverse threads, the two connecting plates 214 move closer to or away from each other. At the same time, the two connecting plates 214 move on the arc surface of the limiting rod 218. The limiting rod 218 can prevent the two connecting plates 214 from deflecting during the movement. The movement of the two connecting plates 214 away from each other drives the two fixing rods 215 to move away from each other. The two fixing rods 215 move away from each other and are respectively inserted into the two fixing grooves 210 on the inner wall of the groove 209 to limit and fix the arch plate 201. When the projector body 1 is not in use, the first dustproof cloth 203 rolled up on the connecting rod 202 is pulled The first dustproof cloth 203 is unfolded and spread on the projector body 1, so that the gravity rod 205 on the first dustproof cloth 203 is hung on the other side of the projector body 1. When the first dustproof cloth 203 is spread, the two second dustproof cloths 204 are respectively turned over and spread on the front and back sides of the projector body 1, thereby the projector body 1 is dust-proofed by the first dustproof cloth 203 and the second dustproof cloth 204. When the projector body 1 needs to be used, the two second dustproof cloths 204 are turned over and spread on the first dustproof cloth 203, and then the connecting rod 202 is driven to rotate by rotating the turntable 220. The arc surface of the turntable 220 is fixed with an anti-skid cover 221, and the anti-skid cover 221 can increase the friction between the hand of the person and the arc surface of the turntable 220, so that the person The turntable 220 is rotated more stably. The turntable 220 is made of titanium alloy. The surface of the turntable 220 made of titanium alloy is relatively hard. Even after long-term use, the turntable 220 made of titanium alloy will not be deformed and has a long service life. The first dustproof cloth 203 and the second dustproof cloth 204 are rolled up by rotating the connecting rod 202. When the rolling is completed, the screw 208 on the inner wall of the rotating connecting plate 207 is inserted between the gear teeth on the gear 206 for fixing. A guide block 219 is fixed at one end of the screw 208. Because the guide block 219 is conical, it is convenient for the screw 208 to be quickly and accurately inserted between the gear teeth on the gear 206. When the first dustproof cloth 203 and the second dustproof cloth 204 need to be cleaned,The two fixing rods 215 are driven to move closer to each other and disengage from the fixing slot 210 by rotating the rotating rod 213 in the opposite direction to release the fixing, and then the arch plate 201 is removed to clean the first dustproof cloth 203 and the second dustproof cloth 204. By setting the adjustment structure 2, the projector body 1 can be conveniently protected from dust when it is not in use.
