[0002] Projection cabinets play an important role in modern display and interactive technologies. They not only have the product display function of traditional display cabinets, but also incorporate advanced projection technology and multimedia interactive elements, thereby greatly improving the display effect and user experience.

[0003] A search revealed that Chinese Patent Publication No. CN209712336U discloses "a liftable holographic projection cabinet, comprising a cabinet body, a lifting box at the top of the cabinet body, a lifting motor inside the lifting box, a transmission gear on the lifting motor, a transmission rod inside the lifting box, a transmission gear in the middle of the transmission rod meshing with the transmission gear, lifting gears at both ends of the transmission rod, and lifting gears meshing with the lifting gears inside the lifting box. The lifting gears are sleeved on the lifting rod, which has threads. The lifting rod extends into the cabinet body and connects to a lifting platform. A holographic projector with a projection screen is mounted on the lifting platform. By setting up a lifting motor, the lifting of the platform is mechanized, eliminating the need for manual lifting. By setting up transmission gears and transmission gears, the mechanical force generated by the lifting motor can be transmitted to the transmission rod for subsequent lifting." However, the following defects still exist:

[0004] (1) However, when the device lifts the holographic projector, one end of the lifting rod will move upward, which will affect the aesthetics of the device.

[0005] (2) However, when the device needs to move the cabinet, it is necessary to push the cabinet directly, which is inconvenient to apply a pushing force to the cabinet, thus affecting the worker's operation.

[0006] Therefore, we made improvements and proposed a multi-functional projection cabinet. Utility Model Content

All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0038] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0039] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0040] like Figure 1-8As shown, this embodiment proposes a multi-functional projection cabinet, including a cabinet body 1, a lifting mechanism 2 is provided inside the cabinet body 1, a moving component 3 is provided outside the cabinet body 1, and a rotating component 4 is provided inside the lifting mechanism 2.

[0041] The lifting mechanism 2 includes a lifting motor 201, a lead screw 202, a screw barrel 203, a lifting plate 204, a holographic projector 205, and a display hole 206. The lifting motor 201 is bolted to the inner bottom wall of the cabinet 1. The lead screw 202 is coaxially arranged at the output end of the lifting motor 201. The screw barrel 203 is threaded to the outside of the lead screw 202. The lifting plate 204 is slidably connected to the inside of the cabinet 1. The holographic projector 205 is arranged above the lifting plate 204. The display hole 206 is formed in the... The top of the cabinet 1, the top of the screw cylinder 203 is rotatably connected to the bottom of the lifting plate 204. When in use, the lifting motor 201, the lead screw 202, the screw cylinder 203, the lifting plate 204 and the holographic projector 205 are all located inside the cabinet 1. When the holographic projector 205 is used for projection, the lifting motor 201 is started, which causes the lead screw 202 to drive the screw cylinder 203, the lifting plate 204 and the holographic projector 205 to rise, and then pass through the display hole 206, and then the projection can be performed.

[0042] like Figure 4 As shown, the movable component 3 includes casters 301, a placement frame 302, a connecting rod 303, and a fixing rod 304. The casters 301 are bolted to the bottom of the cabinet 1. The placement frame 302 is hinged to the outer wall of the cabinet 1. The connecting rod 303 is rotatably connected to one end of the placement frame 302. The fixing rod 304 is fixedly connected to the outer wall of the connecting rod 303 and is slidably connected to the placement frame 302. One end of the fixing rod 304 extends into the wall of the cabinet 1 and is slidably connected to the cabinet 1. When the cabinet 1 is pushed to its destination, the connecting rod 303 is lifted diagonally upwards to disengage the fixing rod 304 from the cabinet 1. Then, the connecting rod 303 is rotated to allow the fixing rod 304 to enter the interior of the placement frame 302. Finally, the placement frame 302 is rotated to make the fixing rod 304 fit against the outer wall of the cabinet 1, allowing for easy storage without compromising aesthetics.

[0043] like Figure 3 As shown, the rotating assembly 4 includes a support platform 401 and a rotating motor 402. The support platform 401 is fixedly connected to the bottom of the holographic projector 205, and the rotating motor 402 is bolted to the top of the lifting plate 204. The output ends of the support platform 401 and the rotating motor 402 are coaxially arranged. When the holographic projector 205 projects, the rotating motor 402 is activated, thereby causing the support platform 401 and the holographic projector 205 to rotate, thus facilitating viewing for people in different positions.

[0044] like Figure 4As shown, a stabilizing rod 5 is fixedly connected to the inner bottom wall of the cabinet 1. The top of the stabilizing rod 5 passes through the lifting plate 204 and is slidably connected to the lifting plate 204. There are two stabilizing rods 5, which are symmetrically arranged. When the lifting plate 204 is raised or lowered, the lifting plate 204 will move along the stabilizing rod 5, thereby improving the stability of the lifting plate 204 when it is raised or lowered.

[0045] like Figure 3 As shown, a shielding ring 6 is bolted to the bottom of the support platform 401, and a blocking ring 7 is bolted to the top of the lifting plate 204. The shielding ring 6 and the blocking ring 7 are slidably connected. When the holographic projector 205 is located above the cabinet 1, the shielding ring 6 and the blocking ring 7 can shield the rotating motor 402, thereby further enhancing the aesthetics of the device.

[0046] like Figure 1 As shown, a storage slot 8 is provided on the side wall of the cabinet 1 to store the placement frame 302 and the connecting rod 303. When in use, the storage slot 8 can store the connecting rod 303 and the fixing rod 304, so that the fixing rod 304 fits more tightly with the cabinet 1.

[0047] like Figure 1 and Figure 7 As shown, an observation hole 9 is provided on the outer wall of the cabinet 1. A connecting plate 10 is fixedly connected to the inner wall of the observation hole 9. A first inclined plate 11 is hinged to the side wall of the connecting plate 10. A second inclined plate 12 is hinged to the side wall of the first inclined plate 11. There are several first inclined plates 11 and two inclined plates 12, which are evenly distributed. When in use, the combined use of multiple first inclined plates 11 and second inclined plates 12 can block the observation hole 9, and at the same time facilitate the observation of the interior of the cabinet 1.

[0048] like Figure 8 As shown, a slide rail 13 is bolted to the inner top wall of the cabinet 1. A baffle 14 is slidably connected inside the slide rail 13 to block the display hole 206. When the holographic projector 205 is not needed, the baffle 14 can block the display hole 206 to prevent dust from falling on the holographic projector 205.

[0049] like Figure 1 As shown, a slide groove 15 is provided on the top of the cabinet 1, and an extension rod 16 is bolted to the top of the baffle 14. The extension rod 16 is located inside the slide groove 15 and is slidably connected to the slide groove 15. When the baffle 14 is moved, the baffle 14 can be operated from the outside through the extension rod 16, which improves convenience.

[0050] like Figure 5 As shown, a round rod 17 is bolted to the outer wall of the cabinet 1. A rubber head 18 is fused to one end of the round rod 17. When the cabinet 1 is pushed to move, the rubber head 18 can prevent the cabinet 1 from directly colliding with external debris and reduce the impact on the cabinet 1.

[0051] Specifically, when using this multi-functional projection cabinet: lift the connecting rod 303 diagonally upwards to rotate the placement frame 302. Then rotate the connecting rod 303 to disengage the fixing rod 304 from the interior of the placement frame 302. Next, press one end of the fixing rod 304 against the outer wall of the cabinet 1 and move it downwards, thereby inserting the fixing rod 304 into the wall of the cabinet 1 and fixing the connecting rod 303. This facilitates moving the cabinet 1. When the device is moved to the desired position, connect the lifting motor 201, the rotating motor 402, and the holographic projector 205 to an external power source. During projection, pinch the extension rod 16 and move it to one side to disengage the baffle 14. Display hole 206, then start lifting motor 201. Lifting motor 201 drives lead screw 202 to rotate, thereby causing screw barrel 203, lifting plate 204, holographic projector 205, rotary motor 402, shielding ring 6 and blocking ring 7 to rise. When lifting plate 204 is in contact with the inner top wall of cabinet 1, lift motor 201 is turned off, and then holographic projector 205 is started to project. During projection, rotary motor 402 is started, and rotary motor 402 drives holographic projector 205 to rotate, thus making it easier for outsiders to view. At the same time, shielding ring 6 and blocking ring 7 can block rotary motor 402, thereby improving the aesthetics of the device.

[0052] All technical features in this embodiment can be freely combined according to actual needs.

[0053] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
