Technical Field

[0001] This utility model relates to the field of alarm device technology, specifically to a fire detection alarm device. Background Technology

[0002] Fire detection alarm devices are used to detect fires within buildings. They are typically smoke detectors, which provide early warnings by monitoring the amount of smoke in the room. These devices are usually installed on the ceiling and are generally fixed to the ceiling by direct adhesive or bolts. Since the alarms are battery-powered, the batteries need to be replaced after a certain number of years of use. The direct fixing method to the ceiling makes it difficult to remove the alarms, which makes battery replacement inconvenient and reduces the user experience.

[0003] In view of this, a design or technical improvement is proposed to solve the above problems.

[0004] The above content is only used to help understand the technical solution of this utility model and does not represent an admission that the above content is the closest prior art. Utility Model Content

[0028] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] like Figure 1-11The fire detection and alarm device shown includes an alarm body 1, an mounting box 2, and two sets of limiting sliding latches 21 on the mounting box 2. The alarm body 1 is equipped with a mounting bracket 22, which contains two sets of inner latch plates 23 that are adapted to and engage with the latches 21. A release assembly is also provided on the mounting bracket 22. The device is fixed to the ceiling via the mounting box 2, and further secured by the engagement between the inner latch plates 23 on the alarm body 1 and the latches 21 on the mounting box 2. This facilitates the installation of the alarm body 1. When the alarm body 1 needs to be removed, the release assembly disengages the latches 21 from the inner latch plates 23, thus improving the ease of installation and removal of the alarm body 1 and optimizing the user experience.

[0030] In one embodiment, the mounting box 2 includes a fixed base plate 3 adapted to be connected with the mounting bracket 22 and a snap-fit ​​frame plate 31 disposed on the fixed base plate 3; the fixed base plate 3 has multiple sets of mounting holes 32; the snap-fit ​​frame plate 31 is hollow inside, and two sets of locking tongues 21 are disposed opposite to each other on the side walls of the snap-fit ​​frame plate 31 for upper limit sliding. When the mounting box 2 is installed, it is fixed to the ceiling by bolts passing through the mounting holes 32, thereby fixing the mounting box 2 to the ceiling as a whole. The alarm body 1 is conveniently assembled by engaging the inner snap-fit ​​plate 23 at its upper end with the locking tongues 21 on the snap-fit ​​frame plate 31.

[0031] In one embodiment, a housing 4 is provided on the outer surface of the snap-fit ​​plate 31 to movably engage the locking tongue 21. A limiting groove 41 is formed on the inner sidewall of the housing 4. Limiting sliders 42 are provided on both sides of the locking tongue 21 to limit its sliding within the limiting groove 41. A first spring 43 is provided between the locking tongue 21 and the inner sidewall of the housing 4. A wedge plate 5 is provided on one end of the locking tongue 21. A first wedge-shaped surface 51, adapted to the wedge plate 5, is provided on the side end of the inner snap-fit ​​plate 23. When the alarm body 1 is assembled with the mounting box 2... When the alarm body 1 is brought close to the mounting box 2, the inner snap plate 23 at its upper end will approach the latch 21. Then, the first wedge-shaped surface 51 on the inner snap plate 23 abuts against the wedge plate 5 on the latch 21, thereby pushing the latch 21 to retract into the housing 4 until the inner snap plate 23 moves to a misalignment with the latch 21. At this time, the latch 21 rebounds under the push of the first spring 43 and abuts against the back side of the inner snap plate 23, thereby fixing the alarm body 1 to the mounting box 2.

[0032] In one embodiment, two sets of inner buckle plates 23 are arranged opposite to each other on the side wall of the mounting bracket 22. The side walls of the mounting bracket 22 are also provided with relief grooves 52 for the locking tongue 21. By setting the relief grooves 52, the locking tongue 21 can move at the relief grooves 52 when the mounting bracket 22 is sleeved with the fixed base plate 3, so as not to affect the sleeved action of the two.

[0033] In one embodiment, the release assembly includes a fixing plate 6 disposed on the inner wall of the mounting bracket 22, a trigger rod 61 movably connected to the side wall of the mounting bracket 22, a connecting frame 62 disposed at the end of the trigger rod 61, a push rod 63 disposed on both sides of the connecting frame 62, and a second spring 64 disposed between the connecting frame 62 and the fixing plate 6; the end of the latch 21 is provided with a second wedge-shaped surface 65 adapted to the push rod 63. When the inner buckle plate 23 and the latch 21 are in the buckling state, by pressing the trigger rod 61 from the side end of the alarm body 1, it causes the push rod 63 to slide within the mounting bracket 22 through the connecting frame 62, thereby forming an abutment with the second wedge-shaped surface 65 at the end of the latch 21, thereby pushing the latch 21 to retract into the housing 4, causing it to be misaligned with the inner buckle plate 23, and thus the alarm body 1 can be pulled down directly to separate it from the mounting box 2.

[0034] In one embodiment, a concealed cover 7 adapted to the fixed base plate 3 is provided on the outer surface of the buckle plate 31. The concealed cover 7 is snap-fitted to the fixed base plate 3. The buckle plate 31 is detachably connected to the fixed base plate 3 through the concealed cover 7. The concealed cover 7 can cover and hide the bolts on the fixed base plate 3, improving the aesthetics of the product. At the same time, the combination of snap-fit ​​splicing improves the ease of assembly of the product.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
