Although some features may be combined to show a possible system design, these features may also be used in other combinations not explicitly described. Thus, the combinations illustrated are not intended to be limiting unless otherwise specified.

The principles of the present invention will be described in detail below with reference to the accompanying drawings and examples.

A waterproof projector comprises a machine core 1 and a sealed machine shell positioned at the periphery of the machine core 1;

the casing comprises a box body 2 with an opening on the front side and a cover plate 3 arranged at the opening of the box body, and a waterproof rubber ring 4 is arranged between the cover plate 3 and the box body 2;

a projection window 21 is arranged on one side of the case opposite to the lens of the machine core 1, and the projection window 21 is sealed by a glass panel 5;

the casing has still been seted up the wiring hole, and water joint 6 is installed to the wiring hole outside.

The size and the opening position of the projection window 21 are different according to the characteristics of the near-focus lens movement and the far-focus lens movement. The technical features of the two models are described below by two embodiments.

Example 1

The embodiment is suitable for the near-focus lens movement.

As shown in fig. 1 to 6, a rectangular projection window 21 is formed on the front surface of the housing, and the projection window 21 is sealed by a glass panel 5 made of ultra-white optical glass.

In this embodiment, the upper portion of the waterproof rubber ring 4 is provided with an arc surface 41;

when the cover plate 3 presses the waterproof rubber ring 4, the pressure intensity of the cambered surface is larger than that of the contact part of the plane structure, and the sealing effect is improved.

In order to further improve the sealing effect, the upper part of the waterproof rubber ring 4 is provided with a convex strip 42 extending in the same direction.

In this embodiment, the external of the box body 2 is provided with a telescopic bracket 7;

when available supports are arranged near the installation position, the projectors can be fixed through the telescopic supports 7.

In the embodiment, the telescopic box further comprises a steering support 8, and the telescopic bracket 7 is connected with the box body 2 through the steering support 8;

the steering support 8 is used for adjusting the projection visual angle of the projector without dead angles, and can be matched with the telescopic support 7 to more conveniently debug the projector after installation;

the steering support 8 comprises a rotating connection 81, a first leg 82 and a second leg 83;

one side of the rotating connecting piece 81 is hinged with the first leg 82 through a first hinge shaft 84;

the other side of the rotating connecting piece 81 is hinged with the second supporting leg 83 through a second hinge shaft 85;
