Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the present invention will be further described in detail with reference to the accompanying drawings and specific embodiments.

Referring to the drawings, the present embodiment provides a dust screen mounting structure, which includes a substrate 1 and a dust screen 2. The base plate 1 is provided with a limiting convex edge 11, and the limiting convex edge 11 is used for guiding the moving path of the dust screen 2.

The substrate 1 is provided with a clamping part which comprises a movable clamping hook 12; one end of the movable hook 12 is hinged with the base plate 1, the movable hook 12 is connected with a hook spring 13, and the hook spring 13 is used for enabling the movable hook 12 to have a resetting trend; the dust screen 2 is provided with a connecting part matched with the clamping part, the connecting part is a hook 21 used for being connected with the movable hook 12, and the end surface of one end of the movable hook 12 opposite to the hook 21 is an inclined surface. The base plate 1 is provided with a pushing component which is in transmission connection with the movable hook 12 and is used for changing the mounting state of the movable hook and the hook; the pushing member includes a linear motor 14 and a slider 141, and the slider 141 is used for transmitting the movement of the linear motor 14 to the movable hook 12.

The base plate 1 is also provided with an ejection component for ejecting the dust screen 2, and the ejection component is a supporting spring 15. The hook 21 is arranged in the middle of the side edge of the dust screen 2, and the 15 supporting springs are symmetrically arranged around the hook 21.

The dust screen mounting structure that this embodiment provided inserts dust screen 2 from predetermined position when using, and dust screen 2 moves along the track that spacing bead 11 formed, and the support spring 15 is constantly compressed to the in-process that dust screen 2 inserted. The hook 21 on the dust screen 2 contacts with the movable hook 12, and because the opposite parts of the movable hook 12 and the hook 21 are inclined surfaces, when the movable hook 12 and the hook 21 are closed, the movable hook 12 and the hook 21 are squeezed to generate transverse split motion. The movable hook 12 rotates with the positioning pin shaft 121 as an original point, is staggered with the hook 21, the hook 21 is inserted, the movable hook 12 resets under the pulling of the hook spring 13, the hanging combination with the hook 21 is realized, and the installation of the dust screen 2 is completed.

When the dust screen 2 needs to be taken out, an electric signal is sent to the linear motor 14 through the control system, the linear motor 14 drives the slide block 141 to push the movable hook 12 to rotate, and the mounting state of the movable rod hook 12 and the hook 21 is released. After the dust screen 2 is loosened, the support spring 15 in a compressed state is restored, and the dust screen 2 is pushed out from the installation position, so that the dust screen can be conveniently taken down for cleaning.

The dust screen mounting structure that this embodiment provided can install the dust screen on the projecting apparatus fast, and need not through automatically controlled can the auto-eject dust screen with the help of the instrument when dismantling, avoids the damage that the instrument dismantlement brought, has greatly promoted the convenience of dust screen dismouting.

The substrate 1 is a structural member for mounting a load-bearing dust screen on the projector, and may be a part of the housing or a partition plate inside the projector in actual use, and the arrangement position and shape thereof do not affect the implementation of the present technical solution.

In other embodiments, one end of the movable hook 12 is fixedly connected to the substrate 1, the movable hook 12 is made of an elastic material, and preferably, the movable hook 12 is made of any one material of polypropylene, polycarbonate, and ABS plastic. Through the elastic deformation of the movable hook 12, the connection and release state switching between the movable hook 12 and the hook 21 can be realized.

The above is only a preferred embodiment of the present invention, and it should be noted that the above preferred embodiment should not be considered as limiting the present invention, and the protection scope of the present invention should be subject to the scope defined by the claims. It will be apparent to those skilled in the art that various modifications and enhancements can be made without departing from the spirit and scope of the invention, and such modifications and enhancements are intended to be within the scope of the invention.
