Patent Application
20190162213
The present invention relates to the field of security and protection, and in particular, to a combined fixing apparatus and an alarm device.
Existing installations, such as alarms, are usually installed by punching. Specifically, a hole is punched on an installation surface (such as a ceiling or wall) first. Then a hanging board (a connecting plate having two ends being plate-shaped connectors) is installed in the hole by using a plastic expansion rubber plug, and a screw is inserted in the plastic expansion rubber plug to fix the hanging board. Next, an alarm body is fixed onto the hanging board by using a snap mechanism.
In an actual operation, if the above installation manner is adopted, manual punching is required in the process of installation, which not only needs to damage an installation surface but also needs to implement the process manually, thus having high labor costs.
Embodiments of the present invention provide a combined fixing apparatus, aimed at solving the problem existing in the prior art that manual punching is required in the process of installation, which not only needs to damage an installation surface but also needs to implement the process manually, thus having high labor costs.

The embodiments of the present invention further provide an alarm device, including:
an alarm; and
a combined fixing apparatus that can be fixedly connected to the alarm, configured to install the alarm on an installation surface;
wherein the combined fixing apparatus includes:
a first fixing part that can be fixed to the installation surface in a punching-free manner; and
a second fixing part that can be fastened to an installation;
wherein the first fixing part and the second fixing part are provided with detachable structures cooperating with each other and reliably connecting the first fixing part to the second fixing part respectively.

In the embodiment of the present invention, the first fixing part is detachably connected to the second fixing part, facilitating assembly and disassembly of installations, and the first fixing part is fixed in the punching-free manner, which can avoid the damage to the installation surface and can reduce labor costs of the installation, improving the working efficiency.
The installation surface may be an object such as a ceiling or a wall. The installation may be an alarm or the like.
In the embodiment of the present invention, the first fixing part and the second fixing part can be connected by using detachable structures, as described in detail as follows:
In Embodiment 1 of the present invention, an implementation manner in which a first fixing part 10 and a second fixing part 20 can be connected by means of clamping after rotation is provided.
Referring to
In Embodiment 1 of the present invention, the first fixing part 10 further includes operable notches 14 disposed oppositely. After the second fixing part 20 is embedded into the borders 12 of the first fixing part 10, by gripping the positions of the operable notches 14 and rotating the second fixing part 20, the first fixing part 10 and the second fixing part 20 rotate relatively to form clamping.
Further, the borders 12 form two borders 12 disposed oppositely under the influences of the operable notches 14 of the first fixing part 10.
Referring to
In Embodiment 1 of the present invention, the second fixing part 20 further includes a first limit structure 23. The first limit structure 23 is disposed on a screw-in side of the second fixing part 20, and can be configured to limit the quantity of screw-in of the second fixing part 20 screwed in the borders 12 of the first fixing part 10. The first limit structure 23 is higher than the snaps 13. Therefore, when the second fixing part 20 rotates to the position where the first limit structure 23 comes into contact with the snaps 13, the first limit structure 23 can stop the snaps 13 from passing and then stop the second fixing part 20 from rotating, to form locked clamping.
In Embodiment 1 of the present invention, the second fixing part 20 further includes a second limit structure 24. The second limit structure 24 is disposed on a side opposite the screw-in side, and is formed by extending outwardly from an edge on one side of the notches 22. The second limit structure 24 is higher than the snaps 13. Therefore, when the second fixing part 20 needs to be removed from the borders 12 of the first fixing part 10, the second fixing part 20 can be rotated to the second limit structure 24, such that the notches 22 disposed on the second fixing part 20 correspond to the snaps 13 on the first fixing part 10, and the second fixing part 20 is separated from the first fixing part 10. By setting the second limit structure 24, the notches 22 can be found quickly, such that the second fixing part 20 is separated from the first fixing part 10 quickly, which is easy to disassemble.
