[0037] In the prior art, the installation mode of the current laser projector is single, one is placed on a horizontal table, and the other is installed below the lifting tool. In view of the single installation structure of the current laser projector, there is a technical problem that cannot adapt to different environments.

[0038] In the technical scheme of the present application, specifically, Figures 1 to 4 , the extension plate mechanism 300 includes a rotating sleeve 351, a first extension plate 311, and a second extension plate 312. The rotating sleeve 351 is vertically arranged and penetrates through the lower side wall of the shell 101. A bearing assembly is arranged between the rotating sleeve 351 and the lower side wall of the shell 101 to enable the rotating sleeve 351 to rotate. The first extension plate 311 and the second extension plate 312 are respectively arranged on both sides of the lower end of the rotating sleeve 351. The first extension plate 311 is slidably connected with the shell 101 through a first sliding assembly, and the second extension plate 312 is slidably connected with the shell 101 through a second sliding assembly.

The first sliding blocks 321 cooperate with the first sliding groove. The second sliding assembly includes second sliding blocks 322 arranged on both sides of the second extension plate 312 and a second sliding groove arranged on the shell 101. The second sliding blocks 322 cooperate with the second sliding groove.

[0040] In combination with FIGS. 4 and Figure 5 , the rotating drive mechanism 200 includes a lifting rod 211 fixed to the upper side wall of the shell 101 and a drive rod arranged inside the lifting rod 211. The lifting rod 211 has a connecting port 212 connected with the external lifting tool 410. The drive rod is arranged to slide up and down inside the lifting rod 211. When the lifting rod 211 is connected with the external lifting tool, the drive rod is pressed downward by the external lifting tool to move downward. The lower end of the drive rod is threadedly connected with the upper end of the rotating sleeve 351, so that when the drive rod moves downward, the rotating sleeve 351 is driven to rotate, thereby driving the first extension plate 311 and the second extension plate 312 to move away from each other. The inside of the lifting rod 211 is provided with an elastic member for driving the drive rod to move upward, so that when the drive rod moves upward, the rotating sleeve 351 is driven to rotate, thereby driving the first extension plate 311 and the second extension plate 312 to move towards each other.

[0041] Specifically, referring to Figure 5The lifting rod 211 is provided with a limiting block 241, the limiting block is provided with a limiting groove, the driving rod is provided with a limiting protrusion 232, the limiting protrusion 232 is vertically arranged upwards and downwards to realize the upward and downward sliding of the driving rod along the inside of the lifting rod 211. The driving rod comprises a first rod part 221 at the upper part, a second rod part 231 at the middle part and a third rod part 241 at the lower part, the limiting block 241 is provided with a through hole for the second rod part 231, the limiting protrusion 232 is arranged on the second rod part 231, and the outer diameters of the first rod part 221 and the third rod part 241 are greater than the outer diameter of the through hole.

[0042] As shown in Figure 4 and Figure 5 , the upper part of the rotating sleeve 351 is inserted into the inside of the lifting rod 211 to be screwed with the third rod part 241. Specifically, the rotating sleeve 351 is provided with a ball internal thread, the third rod part 241 is provided with a screw rod external thread 242, and the ball internal thread is connected with the screw rod external thread 242 in a matched mode.

[0043] Among them, the elastic member is a spring 251, the spring 251 is sleeved on the third rod part 241, one end of the spring 251 is abutted against the upper end of the rotating sleeve 351, and the lower part of the second rod part 231 is provided with a reset flange for abutting against the other end of the spring 251. In some other embodiments, the spring 251 can be sleeved on the outer circle of the second rod part 231, one end of the spring is abutted against the limiting block 214, and the other end is abutted against the first rod part 221, which can also reset the driving rod.

[0044] It can be understood that, in the technical scheme of the present application, by designing the rotating driving mechanism 200 and the extension plate mechanism 300, when the laser projector body 100 is used for installing the lifting appliance, as shown in Figure 6 , specifically, the lifting rod 211 is screwed with the lifting appliance screw rod 420 of the lifting appliance 410, wherein, referring to Figure 4The connecting port 212 of the hoisting rod 211 is provided with a connecting internal thread 213 for connecting with the external lifting device 410. When the hoisting rod 211 is connected with the lifting device screw rod 420, the lifting device screw rod 420 will contact the first rod part 221, press the driving rod downward, and in the process of the driving rod moving downward, the second rod part 231 moves along the length direction of the limiting protrusion 232, and the rotating sleeve 351 threaded with the third rod part 231 will rotate. Then the rotating sleeve 351 drives the driving gear 341 to rotate, and the driving gear 341 drives the first driven rack and the second driven rack to slide. Because the first driven rack and the second driven rack are distributed on both sides of the driving gear 341, when the driving gear 341 rotates, the sliding directions of the first driven rack 331 and the second driven rack 332 distributed on both sides of the driving gear 341 are opposite to each other, thereby driving the first extension plate 311 and the second extension plate 312 to move towards each other, so that the first extension plate 311 and the second extension plate 312 can be retracted. When the laser projector body 100 is hoisted, the first extension plate 311 and the second extension plate 312 are retracted, and the phenomenon of collision can be avoided.

[0045] When the laser projector body 100 is placed on the desktop, the upper part of the spring 251 presses the second rod part 231 to move upward, so that the driving rod is reset upward. In the process of the driving rod moving upward, the rotating sleeve 351 threaded with the third rod part 241 will rotate, and through the driving gear 341 at the lower end, the first driven rack 331 and the second driven rack 332 are driven to slide, thereby driving the first extension plate 311 and the second extension plate 312 to move away from each other, and the first extension plate 311 and the second extension plate 312 are unfolded from both sides of the shell 101. After unfolding, as shown in Figure 1 and Figure 2 illustrated, in this way, the laser projector body 100 can be placed more stably.

[0046] The above describes the embodiments of the present application in detail in combination with the drawings, but the present application is not limited to the above-described embodiments, and various changes can be made within the knowledge range of ordinary skilled in the art without departing from the purpose of the present application.
