The arc surface of the round rod 207 is slidably connected to a fixing block 208, and the fixing block 208 is fixedly connected to one side of the installation frame 202. The arc surface of the round rod 207 is sleeved with a spring 209, and the two ends of the spring 209 are respectively fixedly connected to the round rod 207 and the fixing block 208. The limiting rod 204 is used to fix the installation block 201 in the installation frame 202, so that the fire alarm 1 is fixed in the installation frame 202. The mounting plate 203 is mounted on the mounting frame 202 to improve the efficiency of disassembly and assembly of the fire alarm 1 during maintenance. The mounting plate 203 does not need to be removed to prevent the screws on the mounting plate 203 from loosening and detaching from the wall. The inner wall of the mounting frame 202 is rotatably connected with a plurality of pulleys 210. The arc surfaces of the plurality of pulleys 210 are slidably connected with the mounting block 201. The pulleys 210 reduce the friction between the inner wall of the mounting frame 202 and the mounting block 201, so that the mounting block 201 can slide into and out of the mounting frame 202 more smoothly. A pull rope 211 is fixedly connected to the side of the 06 away from the installation frame 202, and a pull ring is fixedly connected to the end of the pull rope 211 away from the connecting plate 206. The connecting plate 206 is driven to move by operating the pull rope 211 and the pull ring, which is convenient for the user to move the connecting plate 206. A positioning frame 212 is fixedly connected to the side of the mounting plate 203 close to the mounting frame 202. The inner wall of the positioning frame 212 is slidably connected to the pull rope 211.

An anti-skid groove 35 is provided on one side of the support frame 33 at a position corresponding to the positioning rod 32. A plurality of anti-skid protrusions are fixedly connected to the inner wall of the anti-skid groove 35. The anti-skid groove 35 increases the friction between the support frame 33 and the positioning rod 32, so that the positioning rod 32 has a better limiting effect on the support frame 33. A plurality of anti-skid patterns 36 are provided on one end of the positioning rod 32 away from the auxiliary frame 31. The plurality of anti-skid patterns 36 are evenly distributed on the positioning rod 32. The anti-skid patterns 36 increase the friction at the operating end of the positioning rod 32, so that the user can rotate the positioning rod 32 more conveniently.

[0032] The working principle of a fire emergency alarm provided by the utility model is as follows: by setting an adjustment structure 2, first use screws to fix the mounting plate 203 at a specified position on the indoor roof, and then pull the connecting plate 206 in a direction away from the mounting frame 202, and the connecting plate 206 drives the limiting rod 204 and the round rod 207 to move in a direction away from the mounting frame 202. During this process, the limiting rod 204 gradually slides away from the inner wall area of ​​the mounting frame 202, and the round rod 207 slides along the fixing block 208, and the spring 209 is in a compressed state. Then, the fire alarm 1 is operated to approach the mounting frame 202, so that the mounting block 201 completely slides into the inner wall of the mounting frame 202, and then the connecting plate 206 is loosened. The round rod 207 moves in a direction close to the mounting frame 202 under the action of the elastic force of the spring 209, and the round rod 207 drives the connecting plate 206 The fire alarm 1 is fixed on the mounting plate 203. When disassembly and maintenance are required, the connecting plate 206 is pulled to make the limiting rod 204 slide away from the limiting hole 205, release the limiting of the mounting block 201, and move away from the fire alarm 1. The pulley 210 is used to reduce the friction between the inner wall of the mounting frame 202 and the mounting block 201, so that the mounting block 201 can slide in and out of the mounting frame 202 more smoothly. The connecting plate 206 is driven to move by operating the pull rope 211 and the pull ring, so that the user can move the connecting plate 206 conveniently. The pull rope 211 is limited on the mounting plate 203 by the positioning frame 212 to prevent the pull rope 211 from swinging in the air.

[0033] By setting the auxiliary structure 3, the movable frame is first operated to slide into the auxiliary frame 31, and the protective net frame 34 is made to cover the smoke detection port on the fire alarm 1, and then the positioning rod 32 is rotated, and the positioning rod 32 is moved along the auxiliary frame 31 toward the direction close to the support frame 33 with the help of the thread, until the positioning rod 32 is tightly against the support frame 33, so that the position of the protective net frame 34 is fixed. When the protective net frame 34 needs to be disassembled and maintained, the positioning rod 32 is reversed, and the positioning rod 32 is moved away from the support frame 33 along the auxiliary frame 31 with the help of the thread, the limit on the support frame 33 is released, and the support frame 33 is moved away from the auxiliary frame 31, wherein the friction between the support frame 33 and the positioning rod 32 is increased by the anti-slip groove 35, so that the limiting effect of the positioning rod 32 on the support frame 33 is better, and the friction of the operating end of the positioning rod 32 is increased by the anti-slip pattern 36, so that the user is convenient to rotate the positioning rod 32.

[0034] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.

[0035] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention.
