When the supporting platform 2 is used, the supporting platform 2 is fixed on a wall or a bearing table 3 through the fixing support 25, then the bottom case 101 of the laser projection device 10 corresponds to the adjusting component on the supporting platform 2, the laser projection device 10 is supported on the adjusting component, and after the laser projection device 10 is adjusted, the whole laser projection device 10 is fixed through the fastening portion. The supporting platform that this application embodiment provided can also stretch out and draw back along first direction, changes the distance of laser projection equipment to projection screen, realizes the adjustment of throw ratio.

The supporting platform 2 provided by the embodiment of the application further comprises at least one through hole, the through hole is long-strip-shaped, and the central axis of the fastening part penetrates through the through hole.

Specifically, when the adjusting assembly is connected to the fastening portion, if the adjusting assembly 23 penetrates through the supporting platform 2, the width of the through hole is between the adjusting portion 231 and the supporting portion 232, so that the adjusting assembly 23 can slide in the through hole along the first direction, and the fastening portion 24 connected thereto is driven to slide and not fall off; if the adjusting assembly 23' is disposed on the first side of the supporting platform 2, the width of the through hole is between the fastening portion 24' and the adjusting handle 2311', so that the fastening portion 24' can slide in the through hole along the first direction, and the adjusting assembly 23' connected thereto is driven to slide and not fall off. When the adjusting assembly 23 ″ is not connected to the fastening part 24', the width of the through hole may be greater than that of the fastening part 24 ″ so that the fastening part 24 ″ slides in the first direction within the through hole and then is fixed to the bottom case 101 of the laser projection apparatus. The through-hole sets up to the aim at of rectangular shape, and the laser projection equipment model is different, sets up also different in the screw position of its drain pan, consequently through setting up rectangular shape through-hole, thereby can make adjusting part or fastening portion slide along the first direction in the through-hole and the screw cooperation of laser projection equipment drain pan, makes supporting platform be applicable to more laser projection equipment.

As an implementation manner of the present application, when the adjusting assembly is connected to the fastening portion, the whole body of the adjusting assembly connected to the fastening portion slides in the through holes, the number of the through holes is three, and the through holes are matched with the adjusting assembly and arranged in an isosceles triangle, or the number of the through holes is five and arranged in an X shape, or the number of the through holes is seven and arranged along the second direction of the laser projection apparatus 10, and the lengths of the two through holes are different. Since there are errors in the arrangement of the screw holes at the bottom of the laser projection apparatus 10, in order to reduce such assembly errors, the number of through holes may be set to seven, five of which are arranged in an X-shape, and the other two of which are arranged along the second direction, and the distance between the two through holes is greater than the length of the bottom side of the X-shape.

As another implementation manner of the present application, when the adjusting assembly is not connected to the fastening portion, the fastening portion slides in the through hole, since the through hole is used for the fastening portion to pass through, but in order to make the supporting platform suitable for more laser projection apparatuses, the number of the through holes is set to two, the through holes are arranged along the second direction of the laser projection apparatus, and the lengths of the two through holes along the first direction are not consistent.

The above description is only illustrative of the embodiments of the present application and should not be construed as limiting the embodiments of the present application, and any modifications, equivalents, improvements and the like made within the spirit and principle of the embodiments of the present application should be included in the protection scope of the embodiments of the present application.
