[0022] The following is a clear and complete description of the technical solution of the present application in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0023] like Figure 1 As shown, the embodiment of the present application provides a protective cover 100 for an alarm, and the protective cover 100 includes a cover body 1, connecting ears 2 and an adsorption structure 3. The protective cover 100 can protect the alarm.

[0024] The cover body 1 is provided with a cavity 11 with an opening at the top, and the cavity 11 can accommodate the alarm. Optionally, the cover body 1 is cylindrical, so that the cover body 1 can be adapted to the alarm. The material of the cover body 1 can be metal.

[0025] The number of the connecting ears 2 is at least two, and the connecting ears 2 are arranged on the side wall of the cover body 1, for example, the connecting ears 2 are arranged on the outer wall of the cover body 1. Optionally, one end of the connecting ear 2 is connected to the cover body 1 by welding. The number of the connecting ears 2 is set according to the requirements.

[0026] Each connecting ear 2 is provided with an adsorption structure 3, which can be adsorbed on the device where the alarm is located, so as to facilitate the installation of the protective cover 100 on the device where the alarm is located.

[0027] For example, the alarm is a smoke alarm, and the device where the alarm is located is a waste gas treatment device. When the waste gas treatment device is maintained, the smoke alarm is covered with the cover body 1, and the adsorption structure 3 is adsorbed on the top of the waste gas treatment device. The protective cover 100 protects the smoke alarm and reduces the possibility of false alarms of the alarm. After the maintenance is completed, the protective cover 100 is removed from the waste gas treatment device, which is simple to operate.

[0028] In some embodiments, the adsorption structure 3 includes a magnet, and the magnet 3 is disposed on the top surface of the connecting ear 2, so that the magnet 3 can adsorb the device where the alarm is located. In another embodiment, the adsorption structure 3 can also be a suction cup.

[0029] In some embodiments, the magnet is fastened to the connecting ear 2. For example, screw holes are respectively provided on the magnet and the connecting ear 2, and the screw 4 passes through the screw holes on the magnet and the connecting ear 2 to fasten the magnet and the connecting ear 2.

[0030] In some embodiments, the magnet is cylindrical, which is convenient for preparing the magnet. The edge of the magnet is provided with a transition fillet to improve the safety of the magnet.

[0031] like Figure 2 As shown, in some embodiments, the connecting ear 2 includes a bent plate, which is generally stepped to improve the strength of the connecting ear 2. For example, the bent plate includes a first vertical portion 21, a first horizontal portion 22, a second vertical portion 23, a second horizontal portion 24, a third vertical portion 25 and a third horizontal portion 26 in sequence. The first vertical portion 21, the first horizontal portion 22, the second vertical portion 23 and the second horizontal portion 24 form a stepped structure, and the second horizontal portion 24 is higher than the first horizontal portion 22 in the vertical direction. The third vertical portion 25 is bent downward relative to the second horizontal portion 24, and the third horizontal portion 26 is bent from the third vertical portion 25 to a direction close to the second vertical portion 23. The first vertical portion 21 is connected to the side wall of the cover body 1, and the adsorption structure 3 is arranged on the bent plate, for example, the adsorption structure 3 is arranged on the second horizontal portion 24.

[0032] The top surface of the bending plate is higher than the top surface of the cover body 1. The top surface of the bending plate is the top surface of the highest horizontal part of the bending plate. In this embodiment, the top surface of the second horizontal part 24 is higher than the top surface of the cover body 1, which facilitates the adsorption structure 3 to connect to the device where the alarm is located.

[0033] like Figure 1As shown, in some embodiments, the protective cover 100 further includes a buffer 5, which is disposed on the inner wall of the cavity 11. The buffer 5 is made of a flexible material, and when the alarm enters the cavity 11, the buffer 5 can contact the alarm, thereby preventing the alarm from directly contacting the cover body 1 and improving the safety of the alarm.

[0034] In some embodiments, the buffer member 5 includes a rubber strip, which is bonded to the inner wall of the cavity 11. Optionally, the rubber strip is annular, and the thickness of the rubber strip is set according to requirements to meet the requirements of alarms of different specifications.

[0035] In some embodiments, the outer diameter of the cover body 1 is 100 to 200 mm, and it is predicted that the cover body 1 is adaptable to alarms of different specifications.

[0036] like Figure 3 As shown, in some embodiments, the outer wall of the cover body 1 is provided with anti-slip grooves 12 to improve the safety when the protective cover 100 is moved.

[0037] The embodiments of the present application are described in detail above. Specific examples are used herein to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the technical solution and core ideas of the present application. Therefore, changes or deformations made by those skilled in the art based on the ideas of the present application, the specific implementation methods and the scope of application of the present application, all belong to the scope of protection of the present application. In summary, the contents of this specification should not be construed as limiting the present application.
