Description

Technical Field

[0001] The utility model relates to the technical field of smoke alarms, in particular to a disassembly and installation structure of a smoke alarm. Background Art

[0002] Smoke alarm is actually another name for smoke sensor or smoke alarm. Smoke alarm prevents fire by monitoring the concentration of smoke. It uses ion smoke sensor inside. Ion smoke sensor is a technologically advanced sensor with stable and reliable operation. It is widely used in various fire alarm systems and its performance is far superior to gas resistor fire alarm.

[0003] When installing a smoke alarm, in order to ensure its firm installation, it is usually necessary to fix the mounting base of the smoke alarm to the wall surface with expansion bolts, and then the smoke alarm is fixed to the mounting base by clamping. When the smoke alarm needs to be disassembled for maintenance, the disassembly of the smoke alarm at the mounting base will wear the clamping structure, which will cause the smoke alarm to fall off easily during subsequent clamping. In addition, it is difficult to remove the clamping structure, which is not conducive to the disassembly, installation and maintenance of the smoke alarm. For this reason, we propose a disassembly and installation structure for the smoke alarm. Utility Model Content

[0004] The main purpose of the utility model is to provide a disassembly and installation structure for a smoke alarm, wherein a disassembly and installation structure that can be assembled is arranged at the smoke alarm, and after the disassembly and installation structure is pre-fixed on the wall with a split bent plate, the smoke alarm can be installed with a connecting plate, and the flat tube at the connecting plate is clamped and fixed at the extension plate of the bent plate, and when disassembling the smoke alarm, it is only necessary to pull and separate the flat tube and the extension plate, which facilitates the disassembly and installation of the smoke alarm during maintenance, and the flat tube is magnetically connected to the extension plate with a T-shaped magnetic plate at the flat tube. Compared with the existing card-mounted installation structure of the smoke alarm, the extension plate and the flat tube are not prone to wear and looseness problems, which effectively ensures the firmness of the smoke alarm after maintenance, disassembly and installation, and ensures that the smoke alarm can be firmly installed on the wall surface, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] The disassembly and installation structure of the smoke alarm includes a bent plate, a bottom connecting block, an extension plate and a flat tube, wherein upper mounting holes are symmetrically provided on the plate surface of the bent plate, and the extension plate is welded with the bottom connecting block below the bent foot plate of the bent plate, the extension plate is inserted into the flat tube, and the flat tube is fixed to the plate surface of the connecting plate, the upper surface of the flat tube is recessed with a T-shaped opening communicating with the tube cavity, and a T-shaped magnetic plate magnetically attracted to the extension plate is stuck and bonded in the T-shaped opening, a T-shaped countersunk hole is provided on the surface of the connecting plate outside the flat tube, and a fastening bolt is screwed between the T-shaped countersunk hole and the bottom mounting hole provided on the base surface of the smoke alarm.

[0007] Furthermore, a rubber arc sheet is bonded to the plate surface of the extension plate close to the bottom connecting block, and the rubber arc sheet is inserted between the flat tube and the extension plate;

[0008] By adopting the above technical solution, when the extension plate is inserted into the flat tube, the rubber arc sheet can play a role of friction and anti-retraction between the flat tube and the extension plate.

[0009] Furthermore, the hole size of the T-shaped opening is the same as the plate size of the T-shaped magnetic plate, and the hole wall of the T-shaped opening and the plate body of the T-shaped magnetic plate are bonded and fixed with glue;

[0010] By adopting the above technical solution, the T-shaped magnetic plate can be fixed in the T-shaped opening to connect with the magnetic extension plate.

[0011] Furthermore, the head of the fastening bolt is screwed into the large hole cavity of the T-shaped countersunk hole, and the bolt body of the fastening bolt is screwed into the bottom mounting hole of the smoke alarm along the small hole of the T-shaped countersunk hole;

[0012] By adopting the above technical solution, after the fastening bolt is screwed into the bottom mounting hole of the smoke alarm along the T-shaped countersunk hole, the head of the fastening bolt can be hidden in the large hole cavity of the T-shaped countersunk hole.

[0013] Furthermore, a bottom connecting block is welded below the bent foot plate of the bent mounting plate, and an extension plate is welded to the vertical block surface of the bottom connecting block;

[0014] By adopting the above technical solution, the lower part of the bent foot plate of the bent mounting plate can be connected to the extension plate by the bottom connecting block.

[0015] Furthermore, the length of the extension plate is the same as the length of the lumen of the flat tube;

[0016] By adopting the above technical solution, the extension plate can be inserted into the flat tube for adaption and clamping.

[0017] Compared with the prior art, the utility model has the following beneficial effects:

[0018] The utility model provides a disassembly and installation structure that can be assembled at the smoke alarm. After the disassembly and installation structure is fixed to the wall in advance with a split bent plate, the smoke alarm can be installed with a connecting plate, and the flat tube at the connecting plate is clamped and fixed at the extension plate of the bent plate. When disassembling the smoke alarm, it is only necessary to pull and separate the flat tube and the extension plate, which facilitates the disassembly and installation of the smoke alarm during maintenance.

[0019] The flat tube of the utility model is magnetically connected to the extension plate by a T-shaped magnetic plate. Compared with the existing card-mounted installation structure of the smoke alarm, it is not easy to cause wear and looseness between the extension plate and the flat tube, which effectively ensures the firmness of the smoke alarm after maintenance, disassembly and installation, and ensures that the smoke alarm can be firmly installed on the wall surface.
