Description

Technical Field

[0001] The utility model relates to the technical field of projectors, in particular to a multifunctional projector. Background Art

[0002] Projectors are currently a very commonly used projection viewing instrument. They are small, light, easy to carry, and can bring users a good viewing experience when used. Therefore, they are deeply loved by people.

[0003] However, current projectors generally need to be equipped with a bracket for use, and the bracket is used to stably support the projector on the ground, or to be hung on the ceiling of an indoor wall, and then the projector can be used normally.

[0004] It is not difficult to see that a projector that requires an additional bracket to be used will bring certain inconveniences to the user. If the bracket is not prepared temporarily, the projector will be difficult to use normally; and when the projector is not in use, it can only be simply placed without effective protection. If it is accidentally knocked off, the projector will suffer considerable damage. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the above technical difficulties and provide a multifunctional projector, which can be used alone. When in use, the height and the up and down tilt angle of the projector body can be conveniently adjusted, and when not in use, it can be effectively protected by a protective box.

[0006] In order to solve the above technical problems, the technical solution provided by the utility model is:

[0007] A multifunctional projector, comprising a projector body, and further comprising:

[0008] The protective box includes a lower half box and an upper half box; the two are structures in which a square box is divided into two by the inclined planes of the front bottom edge and the rear top edge, and the two are assembled together;

[0009] Positioning structure, the projector body is movably arranged in the lower half box, and after lifting adjustment or upside down adjustment, it is fixed in the lower half box through the positioning structure.

[0010] As an improvement, the tops of the lower half box and the upper half box are hinged to each other, and the left and right sides are fixed together by a fixing structure. The fixing structure includes a T-shaped column, an elastic rope, a ring, a hanging ring and a hook; the end of the T-shaped column is fixed to the lower half box, one end of the elastic rope is tied to a ring that is movably connected to the thin section of the T-shaped column, and the other end is tied to a hanging ring. The hook is fixed to the upper half box, and after being hung with the hanging ring, the elastic rope is tightened. It is convenient to firmly fix the lower half box and the upper half box together after the lids are closed together.

[0011] As an improvement, the positioning structure includes a threaded post, a gasket ring, and a knob nut; threaded posts are respectively fixed on the left and right sides of the projector body, and strip-shaped through holes for the threaded posts to pass through are respectively reserved on the left and right side walls of the lower half box body. A gasket ring movably connected to the inner wall of the lower half box body is sleeved and fixed on the threaded post, and the part of the threaded post extending out of the lower half box body is a threaded rod part, and a knob nut is threadedly sleeved on the threaded rod part. The threaded post moves up and down under the restriction of the strip-shaped through hole. It is convenient to fix the projector body to the lower half box body after the lifting adjustment or the up-and-down flipping adjustment movement of the projector body.

[0012] The advantages of the present utility model compared with the prior art are as follows:

[0013] 1. When the present novelty is in use, the projector body can move up and down and be adjusted by up-and-down flipping in the lower half box body, and can be conveniently fixed by the positioning structure after the movement. In this way, it is possible to conveniently adjust the height and the up-and-down tilt angle of the projector body during use, enabling the user to use the projector more comfortably.

[0014] 2. When the present novelty is not in use, the lower half box body and the upper half box body are covered together and fixed together by the fixing structure. In this way, an effective protection effect can be implemented on the projector body, so that when it is not in use, it is not easily damaged due to reasons such as falling.
