[0021] Refer to Figures 1-4, A fast-opening wired emergency communication device, including an optical terminal 100 and a double-inclined plane bracket 101. The double-inclined plane bracket 101 is provided with a wall-fitting surface 102. Two threaded sleeve rods 200 are rotatably installed on the inner wall of the double-inclined plane bracket 101. The inner walls of the two threaded sleeve rods 200 are both threadedly installed with lead screws 201. The two lead screws 201 are both slidably installed on the double-inclined plane bracket 101. One end of each of the two lead screws 201 away from each other is fixedly installed with a connecting plate 202. One side of each of the two connecting plates 202 is fixedly installed with a sponge pad 203. One end of each of the two threaded sleeve rods 200 close to each other is fixedly installed with a driven bevel gear 300. The two driven bevel gears 300 are both rotatably installed on the inner wall of the double-inclined plane bracket 101. A driving bevel gear 301 is rotatably installed on the inner wall of the double-inclined plane bracket 101. The driving bevel gear 301 meshes with the two driven bevel gears 300. One end of a connecting shaft 302 is fixedly installed on one side of the driving bevel gear 301. The other end of the connecting shaft 302 penetrates through the double-inclined plane bracket 101 and is fixedly installed with a knob 303. The connecting shaft 302 is rotatably installed on the double-inclined plane bracket 101. Two guiding sliders 400 are slidably installed on one side of the double-inclined plane bracket 101. The same L-shaped support plate 401 is fixedly installed on one side of the two guiding sliders 400. The optical terminal 100 is fixedly installed on the L-shaped support plate 401. Positioning bolts 402 are movably installed on the two guiding sliders 400. A plurality of threaded holes 403 are opened on one side of the double-inclined plane bracket 101. The two positioning bolts 402 are respectively threadedly installed in the corresponding two threaded holes 403. During installation, the double-inclined plane bracket 101 can be moved according to the installation position first. The double-inclined plane bracket 101 can use the wall-fitting surface 102 to fit a flat wall surface, or use the two inclined surfaces on both sides of the double-inclined plane bracket 101 to fit the corner of the wall surface for installation. After placing it, the knob 303 can be rotated. The knob 303 will drive the connecting shaft 302 to rotate on the double-inclined plane bracket 101. The rotation of the connecting shaft 302 will drive the driving bevel gear 301 to rotate. When the driving bevel gear 301 rotates, it will drive the two threaded sleeve rods 200 to rotate through meshing with the two driven bevel gears 300. The rotating threaded sleeve rods 200 will drive the limiting ring 209 to rotate in the annular groove 208, thereby avoiding the situation of the threaded sleeve rods 200 shifting and falling off. The continuously rotating two threaded sleeve rods 200 will respectively drive the two lead screws 201 to slide away from each other through two threaded holes 210. The sliding two lead screws 201 will respectively drive the two connecting plates 202 away from each other, so that the two connecting plates 202 drive the two sponge pads 203 to respectively abut against the upper and lower wall surfaces. By setting the sponge pads 203, damage to the wall surface can be avoided. After abutting, the fixation of the double-inclined plane bracket 101 can be completed, thus realizing the installation of the optical terminal 100 without punching holes. Among them, during the movement of the connecting plate 202, the connecting blocks 204 on both sides will be driven to move.When the connecting block 204 moves, it will drive the guiding slide rod 205 to slide in the guiding slide hole 207 on the limiting block 206, thereby restricting the moving directions of the connecting plate 202 and the lead screw 201. And by setting the stop block 211, it can prevent the guiding slide rod 205 from slipping off the limiting block 206.,

[0022] Further, connecting blocks 204 are fixedly installed on both sides of the connecting plate 202. One side of each of the two connecting blocks 204 is fixedly installed with a guiding slide rod 205. Limiting blocks 206 are slidably installed on both of the two guiding slide rods 205. The two limiting blocks 206 are fixedly installed on the double-inclined plane bracket 101. During the movement of the connecting plate 202, it will drive the connecting blocks 204 on both sides to move. When the connecting block 204 moves, it will drive the guiding slide rod 205 to slide on the limiting block 206.,

[0023] Further, a guiding slide hole 207 is formed in the limiting block 206. The guiding slide rod 205 is slidably installed in the guiding slide hole 207. When the connecting block 204 moves, it will drive the guiding slide rod 205 to slide in the guiding slide hole 207 on the limiting block 206, thereby restricting the moving directions of the connecting plate 202 and the lead screw 201.,

[0024] Further, a stop block 211 is fixedly installed at one end of the guiding slide rod 205. The stop block 211 corresponds to the limiting block 206. By setting the stop block 211, it can prevent the guiding slide rod 205 from slipping off the limiting block 206.,

[0025] Further, two annular grooves 208 are formed in the inner wall of the double-inclined plane bracket 101. Limiting rings 209 are rotatably installed in both of the two annular grooves 208. The two limiting rings 209 are respectively fixedly sleeved on the two threaded sleeve rods 200. The rotating threaded sleeve rods 200 will drive the limiting rings 209 to rotate in the annular grooves 208, thereby avoiding the situation that the threaded sleeve rods 200 shift and fall off.,

[0026] Further, a threaded hole 210 is formed in the inner wall of the threaded sleeve rod 200. The lead screw 201 is threadedly installed in the threaded hole 210. The two rotating threaded sleeve rods 200 will respectively drive the two lead screws 201 to slide in opposite directions through the two threaded holes 210. The two sliding lead screws 201 will respectively drive the two connecting plates 202 to move away from each other.,

[0027] Further, two T-shaped sliding grooves 404 are formed in the inner wall of the double-inclined plane bracket 101. T-shaped sliding blocks 405 are slidably installed in both of the two T-shaped sliding grooves 404. The two T-shaped sliding blocks 405 are respectively fixedly installed on the two guiding sliding blocks 400. When the guiding sliding block 400 moves, it will drive the T-shaped sliding block 405 to slide in the T-shaped sliding groove 404, thereby restricting the moving directions of the guiding sliding block 400 and the L-shaped support plate 401.,

[0028] Working principle of the utility model:

[0029] During installation, the double-inclined plane bracket 101 can be moved according to the installation position first. The double-inclined plane bracket 101 can use the wall fitting surface 102 to fit a flat wall surface, or use the two inclined surfaces on both sides of the double-inclined plane bracket 101 to fit the corner of the wall for installation. After placing it, the knob 303 can be rotated. The knob 303 will drive the connecting shaft 302 to rotate on the double-inclined plane bracket 101. The rotation of the connecting shaft 302 will drive the linkage bevel gear 301 to rotate. When the linkage bevel gear 301 rotates, it will drive the two threaded sleeve rods 200 to rotate through meshing with the two driven bevel gears 300. The rotating threaded sleeve rods 200 will drive the limiting ring 209 to rotate in the annular groove 208, thereby avoiding the situation that the threaded sleeve rods 200 shift and fall off. The two continuously rotating threaded sleeve rods 200 will respectively drive the two lead screws 201 to slide away from each other through the two threaded holes 210. The two sliding lead screws 201 will respectively drive the two connecting plates 202 to move away from each other, so that the two connecting plates 202 drive the two sponge pads 203 to respectively abut against the upper and lower wall surfaces. By setting the sponge pads 203, damage to the wall surface can be avoided. After abutting, the fixation of the double-inclined plane bracket 101 can be completed, thereby realizing the installation of the optical terminal 100 without drilling holes. Among them, during the movement of the connecting plate 202, the connecting blocks 204 on both sides will be driven to move. When the connecting blocks 204 move, they will drive the guiding slide rods 205 to slide in the guiding slide holes 207 on the limiting blocks 206, thereby restricting the moving directions of the connecting plate 202 and the lead screw 201. And by setting the stop block 211, it can prevent the guiding slide rods 205 from slipping off the limiting blocks 206. By rotating the two positioning bolts 402, the positioning bolts 402 can be screwed off from the corresponding threaded holes 403. At this time, the restriction on the guiding slider 400 and the L-shaped support plate 401 can be released. By pushing the L-shaped support plate 401, the two guiding sliders 400 can be driven to move. When the guiding sliders 400 move, they will drive the T-shaped sliders 405 to slide in the T-shaped chutes 404, thereby restricting the moving directions of the guiding sliders 400 and the L-shaped support plate 401 and preventing the guiding sliders 400 from slipping off the double-inclined plane bracket 101. Continuously pushing the L-shaped support plate 401 can realize the height adjustment of the optical terminal 100 so as to adjust according to the length of the line. After adjustment, rotating the two positioning bolts 402 again and screwing them into the corresponding threaded holes 403 can complete the fixation.
