Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1, such asFigures 1-4 The present invention provides the following technical solution to address the problem of inconvenient or inefficient repair of the lamp strip in a projector lamp chassis when it malfunctions: A disassembly and assembly mechanism is disclosed.

[0031] The lamp includes a lamp frame 1, a motor 2 mounted inside the lamp frame 1, a transparent cover 3 connected to the side of the lamp frame 1 away from the motor 2, a rotating plate 4 rotatably connected to the side of the motor 2, and a light strip connected to the side of the rotating plate 4; a connecting block 201 is fixed to the output end of the motor 2, positioning grooves 202 are provided on both sides of the connecting block 201, a sliding groove 203 is provided on the side of the connecting block 201 away from the motor 2, and a disassembly and assembly mechanism for replacing the rotating plate 4 is provided on the side of the connecting block 201; rotating plates 401 are connected to both the upper and lower sides of the rotating plate 4, and the rotating plate 4... The surface is equipped with an adjustment mechanism to improve the heat dissipation effect of the chassis lights. The disassembly and assembly mechanism includes a slot 204, which is opened on the side of the rotating plate 4. Guide grooves 205 are opened on both sides of the slot 204. A pressing block 206 slides inside the guide groove 205. The pressing block 206 is engaged with the positioning groove 202. A bidirectional threaded rod 207 is rotatably connected through the pressing block 206, the guide groove 205 and the slide groove 203. The bidirectional threaded rod 207 is threadedly connected to the pressing block 206, and the bidirectional threaded rod 207 is slidably connected to the slide groove 203.

[0032] When the chassis projector lamp is in use, electricity drives motor 2 to run. When motor 2 is running, the output end can drive the rotating plate 4 to rotate. When the rotating plate 4 rotates at high speed, the light strip on the side will light up and form a pattern under high speed. The light strip of the rotating plate 4 is a consumable part. When it is damaged, the bidirectional threaded rod 207 can be rotated to drive the pressing block 206 to slide threadedly. When the pressing block 206 slides threadedly, it can slide through the positioning groove 202 and the guide groove 205. When the pressing block 206 slides out of the positioning groove 202, it pulls the rotating plate 4 to the side. When the rotating plate 4 is pulled, it can drive the slot 204, the bidirectional threaded rod 207 and the pressing block 206 to move. When the slot 204 moves, it can slide through the connecting block 201. When the bidirectional threaded rod 207 moves, it can slide through the slide groove 203. When the rotating plate 4 slides to the end of the connecting block 201, it can be disassembled and replaced, which improves the efficiency of replacing chassis projector lamp parts.

[0033] Example 2, as follows Figure 2 , Figure 3 , Figure 5 and Figure 6The present invention provides the following technical solution to address the problem of low heat dissipation efficiency and insufficient practicality of the projection lamp: An adjustment mechanism is disclosed. The adjustment mechanism includes a gear block 402, which is fixed at the bottom center of a rotating plate 401. The gear block 402 rotates through the interior of the upper and lower sides of the rotating plate 4. A second motor 403 is mounted on the side of the rotating plate 4 away from the rotating plate 401. A drive wheel 404 is fixed to the output end of the second motor 403. One end of a double-headed rack 405 is meshed with the side of the drive wheel 404. The drive wheel 404 is meshed with the gear block 402 inside the upper side of the rotating plate 4. The end of the double-headed rack 405 away from the drive wheel 404 is meshed with the gear block 402 inside the lower side of the rotating plate 4. The drive wheel 404, the gear block 402, and the double-headed rack 405 are connected by a transmission mechanism.

[0034] When the chassis or projector lamp temperature is high, the transparent cover 3 can be removed from the side of the lamp frame 1. Then, start the second motor 403. The output end of the second motor 403 can drive the drive wheel 404 to rotate. When the drive wheel 404 rotates, it can drive the double-headed rack 405 to mesh with the gear block 402 inside the upper side of the rotating plate 4. When the double-headed rack 405 and the gear block 402 mesh and rotate, they can both rotate through the rotating plate 4. When the double-headed rack 405 rotates, it can drive the gear block 402 inside the lower side of the rotating plate 4 to rotate inside the rotating plate 4. The two gear blocks 402 on the upper and lower sides of the rotating plate 4 can rotate synchronously, and the two gear blocks 402 rotate in opposite directions. When the two gear blocks 402 rotate in opposite directions, they can drive the two rotating plates 401 to rotate. When the rotating plate 401 rotates, its angle can be adjusted. By adjusting the angle, the rotating plate 401 can improve the heat dissipation effect of the chassis and improve the practicality of the projector lamp.

[0035] Example 3, as follows Figure 5 and Figure 7 The present invention provides the following technical solution: In order to solve the problem of instability and possible shaking of the rotating plate 401 of the chassis projection lamp during operation, a guide mechanism is disclosed: The side of the rotating plate 4 is also provided with a guide mechanism to improve the adjustment stability of the rotating plate 401. The guide mechanism includes an arc block 406, which is fixed on the side of the rotating plate 4 near the lamp strip. There are two arc blocks 406, and the two arc blocks 406 are symmetrically connected about the central axis of the rotating plate 4. An arc groove 407 is opened through the top of the arc block 406, and a slider 408 slides inside the arc groove 407. The slider 408 is fixed on the side of the upper and lower rotating plates 401.

[0036] When the two rotating plates 401 of the projector lamp rotate in opposite directions, they can drive the slider 408 to rotate. When the slider 408 rotates, it can slide through the arc groove 407. When the slider 408 slides, it can improve the support strength of the rotating plate 401 and guide the rotation of the rotating plate 401, thereby improving the smoothness and stability of the rotating plate 401 when turning and improving the ease of operation of the projector lamp.

[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
