Technical Field

[0001] The utility model relates to the technical field of lighting, in particular to a rotating seat for a projection lamp. Background Art

[0002] A projection lamp is a decorative lamp, and its main function is to project the pattern printed on the projection film onto the wall or ceiling to create a specific environment or scene, such as creating a starry sky environment. Most of the projection lamps on the current market are film-type projection lamps, and their working principle is to place the projection film directly outside the light source and project the image using the principle of pinhole imaging, such as forming a starry sky projection scene. The projection range of the projection lamp with this structure is relatively large, and the atmosphere creation effect is better, for example, images can be projected on the four walls and roof of the room;

[0003] The installation dimensions of the existing projection lamp rotating seat are generally fixed, which makes it impossible to install and fix projection lamps of different sizes and models, so that the rotating seat has certain limitations. At the same time, the projection lamp will have a problem of temperature rise due to long-term operation, and the existing projection lamp rotating seat cannot cool it down, thereby reducing the service life of the projection lamp. In view of the above problems, the inventor proposes a rotating seat for a projection lamp to solve the above problems. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Example: Figure 1-4 As shown, the utility model provides a technical solution: a rotating seat for a projection lamp, comprising a mounting frame 1, a rotating frame 11 is rotatably connected at the center of one end of the mounting frame 1, a rotating seat body 2 is fixedly connected to the end of the rotating frame 11 away from the mounting frame 1, an inner cylinder 22 is inserted at the center of the rotating seat body 2, a rotating disk 24 is rotatably connected to the inner wall of the inner cylinder 22, three fans 25 are fixedly installed at the side end of the rotating disk 24 near the outer ring, an L-plate 27 is symmetrically provided near the center of the end of the rotating seat body 2 away from the inner cylinder 22, a side plate 28 is fixedly connected to the end of the L-plate 27 away from the inner cylinder 22, an insertion shaft 29 is slidably inserted inside the side plate 28, a pull plate 211 is fixedly connected to the end of the insertion shaft 29 away from the rotating seat body 2, a spring 210 is fixedly connected to the side end of the pull plate 211, and the other end of the spring 210 is fixedly connected to the side plate 28, and the spring 210 is sleeved on the outer ring of the insertion shaft 29.

[0020] Two groups of clamping holes 26 are symmetrically provided near the center of the rotating seat body 2 , and the clamping holes 26 are adapted to the insertion shaft 29 .

[0021] By adopting the above technical solution, two groups of clamping holes 26 are provided to cooperate with the insertion shaft 29 to achieve the limiting work of the side plate 1 28.

[0022] A dustproof plate 23 is fixedly connected to one end of the inner cylinder 22 away from the mounting frame 1 .

[0023] By adopting the above technical solution, a dustproof plate 23 is provided at the side end of the inner cylinder 22 to prevent dust from entering the inner cylinder 22 .

[0024] A motor 21 is fixedly mounted on one end of the inner cylinder 22 close to the mounting frame 1 , and an output end of the motor 21 passes through the inner cylinder 22 and is fixedly connected to the rotating disk 24 .

[0025] By adopting the above technical solution, the motor 21 is operated so that the fixedly connected rotating disk 24 is rotated.

[0026] A mounting plate is symmetrically fixedly connected to one end of the mounting frame 1 away from the rotating seat body 2 and close to the center.

[0027] By adopting the above technical solution, two mounting plates are arranged at one end of the mounting frame 1 away from the rotating seat body 2 in order to facilitate the fixed installation of the device.

[0028] Working principle: When the device is in use, by pulling the two pull plates 211, the fixedly connected plug shaft 29 moves away from the motor 21, so as to release the limit work of the L plate 27. After the L plate 27 moves to a suitable position, the pulling force on the pull plate 211 can be released, and then under the elastic action of the spring 210, the plug shaft 29 drives the pull plate 211 to be inserted into the clamping hole 26, so as to complete the limit work of the two L plates 27, so as to realize the limit work of the projection lamp body 3 of different models, thereby solving the problem that the installation size of the rotating seat is generally a fixed model, making it impossible to install and fix projection lamps of different sizes and models;

[0029] By rotating the handle 34, the fixedly connected projection cover 35 is rotated, so as to realize the work of projecting light and shadows of various shapes. When the projection lamp body 3 works for a long time and causes the problem of overheating, the fan 25 and the motor 21 are operated at the same time, so that the fixedly connected rotating disk 24 drives the three fans 25 to rotate, so as to realize the work of heat dissipation of the projection lamp body 3, thereby solving the problem that the projection lamp rotating seat cannot cool the working projection lamp, thereby reducing the service life of the projection lamp.

[0030] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
