DETAILED DESCRIPTION

[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0026] The utility model provides Figure 1-4 The temporary lighting device for indoor construction shown in the figure includes a base 1, a telescopic bracket 2 is fixedly connected to the top of the base 1, and the upper end of the telescopic bracket 2 is fixedly connected to the outer frame 3, and the inner part of the outer frame 3 is movably installed with a mounting frame 4, and the inner part of the mounting frame 4 is buckled and installed with a light panel body 5, the inner part of the outer frame 3 is threadedly connected to a rotating shaft 8, and the inner part of the rotating shaft 8 is movably provided with a linkage shaft 9, and the end of the linkage shaft 9 is fixedly connected to a side wall of the mounting frame 4, and the other side wall of the mounting frame 4 is fixedly connected to an auxiliary shaft 10, and the auxiliary shaft 10 is rotatably connected to the outer frame 3 through a bearing, and further includes:

[0027] The movable component 15, the mounting frame 4 is composed of an arch frame 401 and a connecting rod 402, wherein the arch frame 401 and the connecting rod 402 are movably connected by a spring 1504, and a cavity 1501 is provided inside the connecting rod 402, and the inner wall of the cavity 1501 is fixedly connected to the support rod 1502, and the support rod 1502 can move inside the channel 1503 provided inside the arch frame 401.

[0028] The arch frame 401 and the connecting rod 402 are provided with two symmetrical groups, and the ends of the two groups of arch frames 401 symmetrically arranged above and below are movably connected with the ends of the two connecting rods 402 symmetrically arranged left and right. In this way, the two groups of arch frames 401 in the movable state ensure that the light panel body 5 can be buckled and connected with the mounting frame 4.

[0029] A contact piece 6 is fixedly connected to the inner wall of the upper arch frame 401, and the contact piece 6 matches the contact notch 7 provided inside the light board body 5 to ensure normal lighting of the light board body 5.

[0030] The outer ring of the rotating shaft 8 is provided with a thread 11, and the thread 11 is threadedly connected to the thread groove 12 provided inside the outer frame 3. The end of the rotating shaft 8 is fixedly connected to a turntable. Rotating the turntable drives the rotation of the rotating shaft 8. The thread 11 provided on the outer ring of the rotating shaft 8 is threadedly connected to the outer frame 3. The threaded connection is self-locking, which ensures that the angle of the lamp board main body 5 can be fixed by itself after rotation.

[0031] The end walls of the linkage shaft 9 are fixedly connected with protrusions 13, and the linkage shaft 9 presents a horizontal "T" shape. The outer wall of the "T"-shaped end of the linkage shaft 9 is in contact with and slidably connected to the inner wall of the movable groove 14 set inside the rotating shaft 8, ensuring that the rotation of the rotating shaft 8 drives the rotation of the linkage shaft 9.

[0032] The spring 1504 is movably mounted on the outer ring of the support rod 1502, and the upper and lower ends of the spring 1504 are respectively fixedly connected to the end of the arch frame 401 and the bottom wall of the cavity 1501 set inside the connecting rod 402 close to the arch frame 401. Under the elastic force of the spring 1504, the two groups of symmetrically arranged arch frames 401 are clamped and installed on the lamp board body 5, so as to facilitate the subsequent replacement of the lamp board body 5.

[0033] Working principle: When using a temporary lighting device for indoor construction, first, the rotating shaft 8 fixedly connected to the rotating shaft is twisted by turning the turntable. The rotation of the rotating shaft 8 drives the linkage shaft 9 movably connected to the rotating shaft 8 to rotate, and then drives the lamp board body 5 installed in the mounting frame 4 fixedly connected at the end of the linkage shaft 9 to achieve angle changes. At the same time, with the assistance of the auxiliary shaft 10, the rotation of the mounting frame 4 is guaranteed to be more stable. Since the thread 11 provided on the outer ring of the rotating shaft 8 is threadedly connected to the thread groove 12 provided inside the outer frame 3, the rotating shaft 8 threadedly connected to the outer frame 3 will be displaced during rotation. At the same time, the rotating shaft 8 set in a "T" shape is movably connected to the linkage shaft 9. In this way, when the rotating shaft 8 rotates, the linkage shaft 9 does not affect the movement of the rotating shaft 8, and the threaded connection is self-locking. In this way, no matter how much the rotating shaft 8 rotates, it can ensure that the angle of the lamp board body 5 installed in the mounting frame 4 can be fixed by itself after rotation, which is convenient for the use of the entire lighting device.

[0034] When the lamp board body 5 needs to be replaced later, the lamp board body 5 can be removed by moving the arch frame 401 so that the contact piece 6 leaves the contact slot 7, which is also convenient for subsequent installation.

[0035] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
