Description

Technical Field

[0001] This utility model relates to the field of alarm technology, specifically to an alarm that is easy to maintain. Background Technology

[0002] An alarm is a safety device that can emit an alarm signal when an abnormal situation is detected to remind people to take action. Common alarms include smoke alarms, gas alarms, and burglar alarms. They use sensors to detect specific parameters in the environment, such as smoke, combustible gases, and illegal intrusion. Once these parameters are detected to exceed the safe range, the alarm will immediately emit an audible and visual alarm. Some can also automatically send signals to the monitoring center so that timely measures can be taken to prevent accidents from happening.

[0003] Currently, most alarms on the market are installed by fixing them at high places. This design is particularly inconvenient for maintenance. Due to the high position, maintenance personnel have to rely on ladders or other auxiliary equipment to inspect and maintain them. This is not only complicated to operate, but also greatly reduces maintenance efficiency. Therefore, it is necessary to improve this design. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 This utility model provides a technical solution: an alarm that is easy to maintain, including an outer protective shell 1, and an alarm body 5 that is movably installed inside the outer protective shell 1. The alarm body 5 can emit an alarm signal when an abnormal situation is detected to remind people to take action. The alarm can be a smoke alarm, a gas alarm, a burglar alarm, etc., without limitation. The lower end face of the outer protective shell 1 has a placement opening that is adapted to the alarm body 5. The alarm body 5 is placed inside the placement opening. The bottom of the placement opening has a guide slope to allow the alarm body 5 to enter the placement opening better.

[0023] A rotating roller 3 is rotatably connected inside the outer protective shell 1. A connecting rope 4 is wound around the rotating roller 3, and one end of the connecting rope 4 is fixedly connected to the alarm body 5. A drive component for driving the rotating roller 3 to rotate is installed inside the outer protective shell 1. The drive component includes a micro motor 2 fixedly connected inside the outer protective shell 1, and the output end of the micro motor 2 is fixedly connected to the rotating roller 3. Specifically, the connecting rope 4 on the rotating roller 3 can be used to fix the alarm body 5. By controlling the rotation of the rotating roller 3, the connecting rope 4 can be freely retracted, which makes it easy to adjust the height of the alarm body 5. By lowering it to the ground, it is convenient for staff to perform maintenance. The micro motor 2 can directly drive the rotating roller 3 to rotate, which is convenient to use. Staff can control it in various ways, such as remote control or wired control.

[0024] The bottom of the outer protective shell 1 is provided with a protective component for protecting the alarm body 5. The protective component includes two movable plates 9, which are hinged to the lower end face of the outer protective shell 1 via elastic connecting shafts 11. Each movable plate 9 has several through holes 10. The two movable plates 9 are located below the alarm body 5. The movable plates 9 can provide a closed protection for the alarm body 5 at the bottom of the outer protective shell 1. The through holes 10 on them will not affect the operation of the alarm body 5. A first magnetic block 12 is fixedly connected to each of the two movable plates 9, and a second magnetic block is fixedly connected to the lower end face of the outer protective shell 1. The mutual attraction between the first magnetic block 12 and the second magnetic block can further reinforce the movable plates 9. Specifically, when the alarm body 5 moves down, its own weight can push the movable plates 9 open.

[0025] A partition 7 is fixedly connected inside the outer protective shell 1, and a storage battery 8 is fixedly connected to the partition 7. The micro motor 2 and the alarm body 5 are both electrically connected to the storage battery 8. Baffles 6 are fixedly connected inside the outer protective shell 1 and on the partition 7. The lower end face of the two baffles 6 is in contact with the upper end face of the alarm body 5. The storage battery 8 can provide power to the micro motor 2 and the alarm body 5. The baffles 6 can limit the movement of the alarm body 5.

[0026] Two mounting plates 13 are fixedly connected to the outer protective shell 1. Each mounting plate 13 has a mounting slot. Two pads 14 are fixedly connected to the upper end face of the outer protective shell 1. An observation plate 15 is fixedly connected to the outer protective shell 1. The mounting plates 13 can facilitate the installation and fixation of the device. The pads 14 can fix it more firmly. The observation plate 15 is made of transparent material, which can facilitate the viewing of the internal condition of the outer protective shell 1.

[0027] Working principle: When in use, the device can first be installed at the location of use. During use, the alarm body 5 can monitor the surrounding environment. When maintenance is required after long-term use, the staff can start the micro motor 2 to drive the rotating roller 3 to rotate. By releasing the connecting rope 4, the alarm body 5 can be lowered. After moving it to a lower position, it is convenient for the staff to perform maintenance. The operation is simple and quick. After completion, control the micro motor 2 to reverse so that the alarm body 5 can be reset.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
