DETAILED DESCRIPTION

[0022] 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.

[0023] like Figures 1 to 5 As shown, the utility model provides a waterproof DLP display screen, including a chassis 1, a DLP screen 2 is arranged on the front of the chassis 1, and also includes:

[0024] A waterproof component, which is arranged on the front of the chassis 1 and is used to improve the sealing performance at the edge of the DLP screen 2;

[0025] Among them, the waterproof component includes a fixed frame 3, a cavity 4 is opened inside the fixed frame 3, a first fixed shaft 5 is installed inside the cavity 4, a movable plate 6 is sleeved on the outer surface of the first fixed shaft 5, an extrusion plate 7 is installed on one side of the movable plate 6, a rubber bag 8 is arranged on the inner side of the extrusion plate 7, a plurality of groups of movable frames 9 are hinged on the outer side of the extrusion plate 7, a connecting frame 10 is hinged between two adjacent groups of movable frames 9, a mounting rod 11 is installed on one side of the connecting frame 10, a fixed plate 12 is installed inside the cavity 4, a first spring 13 is sleeved on the outer surface of the mounting rod 11, a baffle 14 is installed on the end of the mounting rod 11, and the baffle 14 is sleeved with the cavity 4.

[0026] The elastic force of the first spring 13 will push the baffle 14. At this time, through the cooperation between the mounting rod 11 and the fixed plate 12, the mounting rod 11 will pull the movable frame 9 through the connecting frame 10, thereby pulling the extrusion plate 7. At the same time, through the cooperation between the movable plate 6 and the first fixed shaft 5, the two extrusion plates 7 will move relative to each other, so that the rubber bag 8 can be squeezed by the extrusion plate 7, so that the rubber bag 8 can cover the DLP screen 2 more tightly, so that the rubber bag 8 is always tightly fitted with the edge of the DLP screen 2 to maintain its sealing effect.

[0027] A slot 15 is formed on the outer side of the chassis 1 , a second fixed shaft 16 is installed inside the slot 15 , and a second spring 17 and a limit frame 18 are sleeved on the outer surface of the second fixed shaft 16 .

[0028] By pressing the baffle 14 and squeezing the inclined surface of the limit frame 18, when the baffle 14 moves to a certain position, since the second spring 17 is in a compressed state, an elastic force will be applied to the limit frame 18, so that the movement of the baffle 14 can be limited by the limit frame 18. At the same time, pressing the baffle 14 will drive the connecting frame 10 through the installation rod 11, so that the movable frame 9 drives the squeezing plate 7 to release the squeezing of the rubber bag 8, thereby not affecting the installation and disassembly operations of the DLP screen 2.

[0029] The rubber bag 8 is filled with liquid, and the rubber bag 8 is wrapped around the edge of the DLP screen 2 .

[0030] The liquid filled inside the rubber bag 8 will deform and fit with the edge of the DLP screen 2 when the extrusion plate 7 squeezes the rubber bag 8, so that it is in close contact with the DLP screen 2 and can be sealed.

[0031] The cavity 4 is provided with 19 inside, and 19 is arranged between the extrusion plate 7 and the rubber bag 8 .

[0032] Through the design of 19, the gap between the two extrusion plates 7 can be blocked, and then when the rubber bag 8 is squeezed, the rubber bag 8 is prevented from entering the gap between the two extrusion plates 7 after being deformed.

[0033] The mounting rod 11 is sleeved with the fixing plate 12 , the first spring 13 is elastically supported between the baffle plate 14 and the fixing plate 12 , and the extrusion plate 7 is in extrusion contact with the rubber bag 8 .

[0034] Through the design of the first spring 13, the baffle 14 has good elastic reset performance. At this time, since the first spring 13 is in a compressed state, an elastic force will be applied to the baffle 14, so that the baffle 14 can drive the mounting rod 11 to make the connecting frame 10 pull the movable frame 9 to drive the extrusion plate 7 to squeeze the rubber bag 8.

[0035] The second spring 17 is elastically supported between the notch 15 and the limiting frame 18 . The end of the limiting frame 18 is provided with a chamfer. One side of the limiting frame 18 can block the baffle 14 when the baffle 14 moves.

[0036] The design of the second spring 17 allows the limiting frame 18 to have good elastic reset performance. At this time, since the second spring 17 is in a compressed state, an elastic force is applied to the limiting frame 18 , so that the baffle 14 can be limited by the limiting frame 18 .

[0037] The working principle and use process of this utility model:

[0038] First, the elastic force of the first spring 13 will exert a pressure on the baffle 14. At this time, the baffle 14 will drive the connecting frame 10 through the mounting rod 11, so that the mounting rod 11 pulls the movable frame 9 through the connecting frame 10. At the same time, through the cooperation between the movable plate 6 and the first fixed axis 5, the two squeezing plates 7 will move relative to each other, so that the rubber bag 8 can be squeezed by the squeezing plate 7. The liquid filled in the rubber bag 8 will be deformed after the rubber bag 8 is squeezed, so that the rubber bag 8 can cover the DLP screen 2 more tightly, thereby maintaining its sealing effect.
