Description

Technical Field

[0001] The utility model belongs to the technical field of projection equipment, in particular to a projector. Background Art

[0002] A projector, also known as a projector, is a device that can project images or videos onto a screen. Existing projectors change the angle of the projector by tilting the handle. However, this method is not only less stable, but also cannot adapt to tilting supports at smaller angles.

[0003] After searching, the Chinese patent document (authorization announcement number CN113311652A) discloses a projector, including: a projector body and a bracket assembly, wherein the projector body includes a shell and a projection assembly contained in the shell and used for projection playback; the bracket assembly includes a fixing part fixedly connected to the shell and a movable part movably connected to the fixing part and rotatably arranged on the shell. The present invention solves the problem in the related art that the projector is not convenient for adjusting the playback angle and needs to use other brackets to achieve the angle adjustment effect by providing a bracket assembly movably connected to the projector body. Although the projector can change the angle of the projector by tilting the handle, this method is not only less stable, but also cannot adapt to tilting support at a smaller angle. Utility Model Content

[0004] The purpose of the utility model is to provide a projector to solve the problems raised in the background technology.

[0005] To achieve the above object, the utility model provides the following technical solution: a projector, comprising:

[0006] The projector body has a hollow assembly plate detachably connected to both sides of the projector body, an H-shaped slider is arranged in the inner cavity of the assembly plate, and a slot for the slider to pass through is opened on the side of the assembly plate;

[0007] Two assembly circular plates are rotatably connected to the sliders through a rotating shaft, and the sides of the two sliders that are away from each other are fixedly connected with fixed arc-shaped tooth plates;

[0008] The movable arc-shaped tooth plate is meshed and connected with the fixed arc-shaped tooth plate. A threaded tube is embedded in the side of the assembly circular plate. The threaded tube is threadedly connected with an adjusting threaded rod. The adjusting threaded rod is rotatably connected with the movable arc-shaped tooth plate through a bearing. The side of the movable arc-shaped tooth plate is connected with a limit rod. A circular channel for the limit rod to pass through is opened on the side of the assembly circular plate.

[0009] The hand piece is fixedly connected to the two assembly circular plates.

[0010] As a preferred embodiment, a plurality of equally spaced threaded channels are provided at the top end of the assembly plate, and fixing threaded rods are threadedly connected to the threaded channels. Circular channels for the fixing threaded rods to pass through are provided at the top end of the slider.

[0011] As a preferred embodiment, a protection plate for protecting the projector body is provided between the two assembly plates, and the protection plate is fixedly connected to the assembly plate through a buckle.

[0012] As a preferred embodiment, an L-shaped side support plate is connected to the top end of the protection plate, and rubber pads for protecting the optical part and the operation part of the projector body are bonded to the side of the protection plate close to the projector body and the bottom end of the side support plate.

[0013] As a preferred embodiment, a plurality of rubber blocks are bonded to the bottom end of the projector body, and anti-slip lines are provided at the bottom end of the rubber pad.

[0014] As a preferred embodiment, the carrying handle includes two hollow tubes respectively fixedly connected to the assembly circular plate, and a C-shaped carrying rod is jointly arranged in the inner cavities of the two hollow tubes.

[0015] As a preferred embodiment, threaded holes are provided on the side surface of the hollow tube, auxiliary threaded rods are threadedly connected to the threaded holes, and a plurality of circular holes for the auxiliary threaded rods to pass through are provided on the side surface of the carrying rod.

[0016] Compared with the prior art, the technical effects and advantages of the present utility model are as follows:

[0017] For this projector, when it needs to be carried, it can be carried and moved by holding the carrying rod. When the angle needs to be adjusted, the meshing and fixing of the movable arc-shaped tooth plate and the fixed arc-shaped tooth plate are released, then the relative angle between the projector body and the carrying handle is changed, and the adjusting threaded rod is rotated so that the movable arc-shaped tooth plate and the fixed arc-shaped tooth plate are meshed and connected to ensure stability. After landing, the stability of the inclination of the projector body is ensured, and it can also adapt to the inclination support at a small angle.

[0018] For this projector, after the relative angle between the projector body and the carrying handle is fixed, the adjustable design of the carrying rod of the carrying handle and the hollow tube changes the distance between the carrying rod and the assembly circular plate. Coupled with the position adjustment of the slider and the assembly plate, the distance between the landing end of the projector body and the assembly circular plate is changed, thereby changing the angle between the carrying rod and the ground, and realizing the re-adjustment of the actual use angle of the projector body.

[0019] For this projector, the rubber pads of the protection plate and the side support plate can protect the optical part and the operation part of the projector body, reducing the influence of external forces during carrying.

[0020] This projector can not only be inclined and supported, but also be protected. Description of the Drawings
