[0002] A projector is a device that can project images or videos onto a screen. It can be connected to computers, VCDs, DVDs, BDs, game consoles, DVs, etc. through different interfaces to play corresponding video signals. It is widely used in homes, offices, schools and entertainment venues. Depending on the working method, there are different types such as CRT, LCD, DLP, 3LCD, etc. However, it often requires a supporting device to cooperate with each other during use, and the supporting device must support it for stable use.

[0003] The existing projector support device is a device used to support and fix the projector, and is usually made of metal or aluminum alloy. For example, the Chinese patent with publication number CN218178412U and name: Projector Support, is to place the projector inside a rectangular placement plate and clamp it through an adjustment structure, so that the projector can be quickly fixed for use. However, due to different usage scenarios of different users, the support structure is placed in different positions during use. Therefore, in some occasions, due to the influence of unequal placement positions, it is necessary to finely adjust the height of one side of the projector placed on the support device platform, so that the projection effect can be improved to meet the situation of autonomous projection. Therefore, the present application provides a projector support device to meet the needs. Utility Model Content

In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0026] Combine the following Figure 1-4 The embodiment shown describes the technical solution of the utility model:

[0027] It includes a placement rack 1, the interior of the placement rack 1 is rotatably connected to a supporting plate 3 through an installation shaft 2, and the bottom of the supporting plate 3 is fixedly connected to a plurality of elastic members 4, the bottom end of the elastic member 4 is fixedly connected to the placement rack 1, and the bottom of the supporting plate 3 is fixedly connected to a plurality of mounting seats 5, the bottom of the placement rack 1 is fixedly connected to a support frame 7, and the interior of the support frame 7 is slidably connected to two support plates 6, the support plate 6 and the mounting seat 5 are rotatably connected, and the support plate 6 supports the support plate 3 through the mounting seat 5.

[0028] During its use, the support frame 7 can be directly placed on a flat surface, and the projector can be placed on top of the support plate 3, and the projector can be supported by the support plate 3. At this time, the support plate 6 can be directly pulled to make it slide under force. Since the top of the support plate 6 is rotationally connected to the mounting seat 5, the sliding force of the support plate 6 itself can be converted into a rotating force on itself, thereby changing the angle between itself and the support frame 7, and then changing the height position of its top. The mounting seat 5 applies a longitudinal thrust to the support plate 3, so that the support plate 3 will rotate along the mounting shaft 2 under the action of its thrust, and then the horizontal angle of the projector can be adjusted to ensure the stability of the projection.

[0029] Two guide grooves 10 are provided inside the support frame 7 , and the inside of the guide groove 10 is slidably connected to a same sliding block 8 via two electric push rods 11 , and the top of the sliding block 8 is rotatably connected to the bottom of the support plate 6 .

[0030] During its use, the electric push rod 11 can be directly controlled by an external controller, so that the electric push rod 11 is driven by force to drive the sliding block 8 to move. At this time, the sliding block 8 can effectively transmit its rotational force to the support plate 6, so that the support plate 6 can move and adjust autonomously under the action of its force, thereby simplifying its overall adjustment steps and making it more convenient during adjustment.

[0031] A guide rod 12 is fixedly connected inside the guide groove body 10 , and the guide rod 12 is arranged between the two electric push rods 11 . A through hole is opened on the side wall of the sliding block 8 , and the guide rod 12 passes through both sides of the sliding block 8 through the through hole.

[0032] When the sliding block 8 is moved by force, the sliding block 8 can slide along the guide rod 12 through the through hole under the action of its moving force. At this time, the setting of the guide rod 12 will effectively limit the moving trajectory of the sliding block 8, so that the sliding block 8 can slide stably under the action of its force, thereby ensuring the stability of its overall adjustment and avoiding the possibility of deviation.

[0033] A support shaft 9 is fixedly connected inside the support frame 7 , and two sides of the support shaft 9 penetrate through two sides of the support plate 6 , so that the support plate 6 can rotate along the support shaft 9 .

[0034] When the support plate 6 is moved by force, its moving force will rotate along the central axis of the support shaft 9 under the action of the support shaft 9, thereby changing the angle between the support plate 3 and the support frame 7 and the support plate 6, so that the support plate 6 can better adjust the height of the support plate 3.

[0035] A square opening 16 is formed on the support plate 6 , and the support plate 6 forms an L-shaped structure through the square opening 16 , and the two square openings 16 are arranged opposite to each other.

[0036] The setting of the L-shaped structure can effectively increase the installation space between the side wall of the support plate 6 and the mounting seat 5, so that the support plate 6 can be rotatably connected to the three mounting seats 5 at the same time, and then increase the connection points between the support plate 6 and the support plate 3, so that the moving force of the support plate 6 will be evenly transmitted to the side wall of the support plate 3, thereby driving the support plate 3 to be stably adjusted.

[0037] A clamping plate 15 is disposed inside the placement rack 1 , and the supporting plate 3 and the two clamping plates 15 form a concave structure, and the side walls of the clamping plates 15 are fixedly connected to the placement rack 1 via a plurality of compression springs 14 .

[0038] During its use, the projector can be directly placed between the two clamping plates 15. At this time, the clamping plate 15 can transfer the thrust of the projector to the compression spring 14, so that the compression spring 14 is deformed and shortened due to the force, and then drives the clamping plates 15 to move synchronously, so that the two clamping plates 15 are moved away from each other, and then the space between the two clamping plates 15 is increased, so that the projector can be effectively placed. After it is placed, you can directly let go. At this time, the reaction force of the compression spring 14 will push the clamping plate 15 to reset itself, and then clamp and fix the projector.

[0039] A plurality of anti-slip strips 13 are fixedly connected to the top of the supporting plate 3, and the plurality of anti-slip strips 13 are horizontally distributed.

[0040] The provision of the anti-slip strip 13 can effectively increase the contact friction between the projector and the supporting plate 3, making the projector more stable during its use and avoiding the possibility of movement due to its own gravity and the like.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
