Description
Technical Field
[0001] The utility model relates to the field of alarm disassembly and assembly structures, in particular to a convenient disassembly and assembly structure for an alarm. Background Art
[0002] In the fire alarm system, smoke alarm is the most common alarm. At present, smoke alarm is generally installed on the top of the wall of the building. After installation, during use, the smoke alarm needs to be regularly inspected and maintained (maintenance means that dust adheres to the smoke sensing area of the alarm during use, affecting the sensitivity of the alarm, and the dust needs to be cleaned) to ensure its normal use and sensitivity. At present, the installation of smoke alarm generally adopts the method of thread solidification. When disassembling and assembling the smoke alarm, the staff needs to climb up and use a screwdriver to twist it from bottom to top. This method not only reduces the efficiency of disassembly and assembly, but also makes the staff more laborious due to the operating angle. In order to solve the problems mentioned in the above background, we propose a convenient disassembly and assembly structure for the alarm. Utility Model Content

[0005] By adopting the above technical scheme, the utility model has four slots installed on the fixing seat, and connecting blocks and reset springs are installed inside the slots. When the smoke alarm is placed between the clamping arms on the four connecting blocks, the clamping arms clamp the smoke alarm under the action of the reset springs, and the positions of the clamping arms can be adjusted according to the size of the smoke alarm, thereby improving the convenience and applicability of disassembly and assembly. By installing a connecting beam on the supporting block, when the smoke alarm is clamped between the four clamping arms, the supporting block and the connecting beam can be clamped on the bottom shell of the smoke alarm facing the smoke part. Through the design of the limiting arm and the clamping seat, the supporting block and the connecting beam can be clamped together with the clamping arms on the fixing seat, thereby ensuring that the clamping arms clamp the smoke alarm while preventing the smoke alarm from falling due to gravity, thereby improving the stability of the fixation.

[0013] By adopting the above technical solution, the friction between the clamp arm and the housing of the smoke alarm is improved to prevent the housing of the smoke alarm from being worn.
[0014] The utility model is further configured as follows: a first limiting bolt is threadedly connected to the top of the limiting arm, and the first limiting bolt is used in conjunction with the connecting beam.
[0015] By adopting the above technical solution, the position of the limiting arm on the connecting beam is limited.
[0016] The utility model is further configured as follows: the opposite sides of the four limit arms are all threadedly connected with a second limit bolt, and the second limit bolt is used in conjunction with the extension block.
[0017] By adopting the above technical solution, the position of the extension block inside the extension groove is limited.
[0018] The utility model is further configured as follows: a protrusion which is engaged with the card seat is integrally processed on one side of the four card arms which are opposite to each other.
[0019] The above technical solution is adopted to facilitate the mutual limiting of the clamping arm and the clamping seat.
[0020] The utility model is further configured as follows: sliding blocks are symmetrically provided on the connecting beam, and sliding grooves used in conjunction with the sliding blocks are provided on the limiting arm.
[0021] The above technical solution is adopted to perform sliding limiting on the limiting arm.

[0025] 1. The utility model has four slots installed on the fixing seat, and connecting blocks and reset springs are installed inside the slots. When the smoke alarm is placed between the clamping arms on the four connecting blocks, the clamping arms clamp the smoke alarm under the action of the reset springs, and the position of the clamping arms can be adjusted according to the size of the smoke alarm, thereby improving the convenience and applicability of disassembly and assembly;
[0026] 2. The utility model installs a connecting beam on the supporting block. When the smoke alarm is stuck between four clamping arms, the supporting block and the connecting beam can be clamped on the bottom shell of the smoke alarm facing the smoke. Through the design of the limiting arm and the clamping seat, the supporting block and the connecting beam can be clamped together with the clamping arm on the fixing seat, which ensures that the clamping arm clamps the smoke alarm tightly and prevents the smoke alarm from falling due to gravity, thereby improving the stability of the fixation.
