DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0022] See also Figure 1 to Figure 4 The utility model provides an adjustable projector support rod device, comprising: a support plate 1, the edge of the support plate 1 is evenly provided with mounting grooves 2, and the inner walls on both sides of the mounting grooves 2 are provided with connecting tooth holes 3, the center of the upper surface of the support plate 1 is fixedly connected with a heat dissipation fan 4, and the top of the heat dissipation fan 4 is fixed with a placement plate 5, the middle part of the placement plate 5 is penetrated, and a heat dissipation net 7 is installed at the center of the upper surface of the placement plate 5;

[0023] Specifically, the placement tray 5 is through-through in the middle, and the wind blown out from the heat dissipation fan 4 can pass through the placement tray 5 and act on the projector installed above the placement tray 5 via the heat dissipation net 7, thereby dissipating the bottom of the projector and helping the projector to operate normally.

[0024] A movable groove 6 is transversely arranged in the middle of the upper surface of the placing plate 5, and a support plate 8 is slidably installed inside the movable groove 6. There are two support plates 8 in total, and an elastic telescopic rod 9 is connected between the support plates 8. A bow plate 10 is fixed above the ends of the support plates 8 that are close to each other, and a connecting hole 11 is penetrated inside the upper part of the bow plate 10. A spring telescopic column 12 is fixed on the upper surface of the support plate 8, and a baffle 13 is fixed above the ends of the support plates 8 that are far away from each other.

[0025] Specifically, the two support plates 8 are respectively located on both sides above the placement plate 5 and can be moved along the movable groove 6 to match projectors of different sizes. The two support plates 8 are pulled by two elastic telescopic rods 9, which makes there be an elastic force between the support plates 8. After the projector is placed on the support plate 8, the support plates 8 can be close to each other, and then the projector can be clamped by the baffle 13. The bow plate 10 is used to separate the projector and the support plate 8, which helps to dissipate heat from the bottom of the projector and is convenient for connecting and fastening the bottom of the projector. The screws are passed through the connecting holes 11 and locked to the bottom surface of the projector. The projector is fixed on the support plate 8. The spring telescopic column 12 is also elastic. The spring telescopic column 12 supports the projector so that the projector is placed in a balanced and stable manner.

[0026] The inner side of the installation groove 2 is rotatably connected with a connecting rod 14, and the connecting shaft end at the top of the connecting rod 14 is provided with a sawtooth structure, and the connecting shaft end at the top of the connecting rod 14 is respectively meshed with the connecting tooth hole 3;

[0027] Specifically, the rotational connection between the connecting rod 14 and the supporting plate 1 is not an ordinary rod hole connection, but a rotational connection achieved by engaging with each other through a hole with a serrated structure, i.e., the connecting tooth hole 3, and an axis with a serrated structure, i.e., the connecting axis at the top of the connecting rod 14. This connection method enables the connecting rod 14 to rotate at an angle and stop at the angle, thereby ensuring the stability of the structure.

[0028] The lower part of the connecting rod 14 is rotatably connected with an attachment rod 15, and the lower end of the connecting rod 14 is provided with a locking tooth hole 16 which is transversely penetrated inside, and the inner side of the locking tooth hole 16 is matched with a gear shaft 17 which is respectively fixed on both sides of the top of the attachment rod 15, and the lower part of the attachment rod 15 is fixed with an attachment plate 18, and the interior of the attachment plate 18 is penetrated with positioning holes 19 at equal distances;

[0029] Specifically, the rotational connection between the attachment rod 15 and the connecting rod 14 is the same as the rotational connection structure between the connecting rod 14 and the support plate 1. Both of them are rotational connections achieved by the mutual meshing of a hole with a serrated structure and an axis with a serrated structure. The meshing cooperation of the gear shaft 17 and the locking gear hole 16 is used to achieve the angle adjustment of the attachment rod 15 and the connecting rod 14, and the attachment rod 15 and the connecting rod 14 remain stationary after the angle is adjusted. In this way, when installed and fixed, the structure between the attachment rod 15, the connecting rod 14 and the support plate 1 is stable, the angle between the support plate 1 and the connecting rod 14 is adjustable, and the angle between the connecting rod 14 and the attachment rod 15 can also be adjusted. In this way, the structure of the entire support rod device is highly flexible and can be deformed at will to match different installation positions.

[0030] The working principle of the utility model is:

[0031] The support rod device can be flexibly adjusted and deformed at will to match different installation positions, for example: pull the connecting rod 14 to the four sides or keep the connecting rod 14 stationary, turn each attachment rod 15 to the horizontal, and each attachment rod 15 can be attached to the horizontal surface to achieve horizontal installation; for example: pull the connecting rod 14 directly to be level with the support plate 1, and each attachment rod 15 can be attached to the vertical surface for vertical installation; for example: adjust the angle between the connecting rod 14 and the support plate 1 respectively, and then adjust each attachment rod 15 so that each attachment rod 15 is placed on the same inclined plane, so that each attachment rod 15 can be attached to the inclined surface, and the installation is complete. For example, the connecting rod 14 is adjusted to form an angle with the supporting plate 1, and then the attachment rods 15 are adjusted to form a vertical angle between two adjacent attachment rods 15, so that the support rod device can be installed at the corner position, and the projector is installed and fixed on the support plate 8, and screws are passed through the connecting holes 11 on the bow plate 10, and then locked to the bottom surface of the projector. The two sides of the projector are clamped by the baffles 13, so that the projector is stably installed. After the projector starts working, the heat dissipation fan 4 is started synchronously, and the wind generated by the heat dissipation fan 4 reaches the bottom of the projector through the heat dissipation net 7 to dissipate heat from the bottom of the projector.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
