DETAILED DESCRIPTION

[0025] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] Embodiment 1: A waterproof water curtain projection frame bottom shell, see Figure 1-Figure 4 As shown, it includes a bottom shell 1, a threaded tube 102, a positioning column 104 and a connection port 2. Four blind holes 101 distributed in an annular manner are opened on one side of the bottom shell 1. Four threaded tubes 102 distributed in an annular manner are fixedly connected to one side of the bottom shell 1 by means of plastic molding. Four threaded holes 103 distributed in an annular manner are opened in the middle of the bottom shell 1. The threaded holes 103 are through holes. Two positioning columns 104 are fixedly connected to the middle of the bottom shell 1 by means of plastic molding. A connection port 2 for connecting a connection line is provided on the bottom shell 1. The bottom shell 1 is made of ADC12 aluminum. The surface of the bottom shell 1 is sprayed with matte fine sand grain black powder. It also includes a first airbag 3 , an air guide tube 4, a positioning frame 5, a second airbag 6, a push plate 7, a connecting plate 8, a mounting plate 9 and a fixing assembly. Four mounting plates 9 are installed on the circumferential edge of the bottom shell 1 by welding. A connecting plate 8 is slidably arranged in the mounting plate 9. Push plates 7 are commonly installed on the four connecting plates 8 by welding. Four positioning frames 5 are fixedly connected to the circumferential edge of the bottom shell 1 by welding. The second airbag 6 is sleeved on the positioning frame 5. The first airbag 3 is installed on the inner edge of the bottom shell 1. The first airbag 3 and the second airbag 6 are commonly connected and communicated with the air guide tube 4. Each second airbag 6 is fixedly connected to the push plate 7.

[0027] See also Figure 4 As shown, the fixing assembly includes an iron sheet 11 embedded in the connecting plate 8, and a magnet 10 is mounted on the mounting plate 9 by welding, and the magnet 10 and the iron sheet 11 attract each other.

[0028] When it is necessary to assemble the bottom shell 1 with the upper frame, the upper frame is accurately docked with the bottom shell 1 through the positioning column 104 and the blind hole 101, and the upper frame is connected and installed with the bottom shell 1 by screwing into the threaded barrel 102 and the threaded hole 103. Then, the second airbag 6 is compressed by pushing the push plate 7 to make the connecting plate 8 slide in the mounting plate 9, so that the iron sheet 11 is close to the magnet 10, and the iron sheet 11 is adsorbed by the magnet 10 to fix the connecting plate 8 on the mounting plate 9. After the second airbag 6 is compressed, the air inside it is input into the first airbag 3 through the air duct 4, so that the first airbag 3 expands, so as to fill and seal the gap between the bottom shell 1 and the upper frame to prevent water from penetrating into the shell.

[0029] Example 2: Based on Example 1, refer to Figure 5 and Figure 6 As shown, it also includes a guide rod 13 installed on both sides of the connecting port 2 by welding, a connecting seat 14 is slidably provided on the guide rod 13, two connecting rods 15 are hingedly connected to the connecting seat 14, the two connecting rods 15 at the upper part of the two connecting seats 14 are hingedly connected to an anti-slip splint 12, and the two connecting rods 15 at the lower part of the two connecting seats 14 are hingedly connected to another anti-slip splint 12, and the two anti-slip splints 12 are symmetrical in style and have a semicircular notch in the middle.

[0030] When the transmission line needs to be connected, the connecting seats 14 on both sides are pushed to slide along the guide rods 13 toward the side close to each other. At this time, the first elastic member 16 is compressed and deformed by the force, and then the two anti-dropout clamps 12 are pushed to move away from each other through the connecting rod 15, and then the transmission line is connected from the connecting port 2. After the connecting seat 14 is loosened, the first elastic member 16 loses the force and returns to its original state, and then pushes the connecting seat 14 to slide away from each other, so that the two anti-dropout clamps 12 are close to each other and clamp the transmission line to prevent the transmission line from being pulled out and disconnected.

[0031] See also Figure 7 As shown, it also includes a mounting seat 17 installed on the outside of the bottom shell 1 by bolt connection, two clamping rods 18 are slidably arranged on both sides of the mounting seat 17, and two limit plates 19 are installed on the bottom shell 1 by bolt connection. The two limit plates 19 are respectively located on both sides of the mounting seat 17. The clamping rod 18 is slidably connected to the limit plates 19 on the same side. A second elastic member 20 is wound around the clamping rod 18, and the second elastic member 20 is located between the mounting seat 17 and the limit plates 19. The second elastic member 20 is used to push the clamping rods 18 on both sides to approach each other.

[0032] When the bottom shell 1 needs to be installed on the bracket, the clamping rods 18 on both sides are pulled to slide away from each other. At this time, the second elastic member 20 is compressed and deformed by the force, and then the mounting seat 17 is put on the bracket and the clamping rod 18 is released. The second elastic member 20 loses the force and returns to its original state, thereby pushing the clamping rod 18 to penetrate the mounting seat 17 and engage with the bracket, so that the bottom shell 1 is installed on the bracket.

[0033] See also Figure 3 and Figure 7 As shown, a telescopic sleeve 21 is sleeved on the clamp rod 18, and a rubber ring 201 is sleeved in the threaded hole 103. The telescopic sleeve 21 is telescopic with the sliding of the clamp rod 18, and is used to protect the second elastic member 20 from being damaged; the rubber ring 201 is used to enhance the tightness of the connection between the threaded hole 103 and the screw, prevent the screw from falling off, and prevent water from penetrating.
