[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Example 1

[0025] like Figure 1 As shown;

[0026] A protective mechanism for a fire alarm comprises an alarm 1.

[0027] In this embodiment: the existing disclosure (announcement) number: CN219228004U discloses a protection mechanism based on a fire alarm. In order to solve the existing problems existing in this prior art, as disclosed in the background technology above, "due to the existing alarm protection mechanisms, most of them are fixedly installed on the surface of the alarm, and the alarm needs to be inspected and maintained regularly. Since the protection mechanism is not easy to disassemble, the staff will encounter obstacles when repairing the alarm." In terms of combined use, this problem is obviously a problem that exists and is difficult to solve. In view of this, in order to solve this technical problem, the installation component 2 and the protection component 3 are added to this application document.

[0028] More specifically:

[0029] like Figures 1 to 4 As shown:

[0030] In combination with the above content: it also includes a mounting component 2 arranged on the surface of the alarm 1;

[0031] The mounting assembly 2 includes a mounting base 21 which is sleeved on the surface of the alarm 1. Two vertical plates 1 23 and two vertical plates 24 are symmetrically arranged on the surface of the mounting base 21. A mounting groove 25 is provided on the surface of the mounting base 21. The vertical plate 1 23 and the vertical plate 24 are slidingly connected to the mounting base 21 through the mounting groove 25. Two spring pins 26 are provided on the four sides of the mounting base 21. The pin portion of each spring pin 26 passes through the surface of the mounting base 21 and extends into the mounting groove 25, and is slidingly connected to the vertical plate 1 23 and the vertical plate 24. The ends of the two spring pins 26 arranged on the same side are fixedly connected to a baffle 27, and a hinge seat 29 is provided between the baffle 27 and the mounting base 21. The hinge seat 29 is fixedly connected to the surface of the mounting base 21, and the rotating shaft portion of the hinge seat 29 is rotatably connected to a block 210. The surface of the baffle 27 is provided with a card slot 28 adapted to the block 210.

[0032] In this embodiment: since the surface of the alarm 1 is provided with a mounting base 21, when the staff needs to remove the vertical plate 1 23 and the vertical plate 24, they can pull the baffle 27. At this time, the baffle 27 drives the spring pin shaft 26 to disengage from the slot 28, and then the block 210 connected by rotating on the surface of the hinge seat 29 is inserted into the slot 28, thereby separating the vertical plate 1 23 and the vertical plate 24 from the mounting base 21. This design can facilitate the staff to repair the alarm 1.

[0033] Going further:

[0034] In an optional embodiment, four mounting plates 22 are fixedly connected to the surface of the mounting base 21 .

[0035] In this embodiment, since the surface of the mounting base 21 is provided with a mounting plate 22 , with this design, a worker can install the mounting plate 22 on the wall surface through the threaded bolts provided on the surface of the mounting plate 22 .

[0036] Going further:

[0037] In an optional embodiment, the vertical plate 1 23 and the vertical plate 24 are connected by bolts 211 .

[0038] In this embodiment, since the bolts 211 are provided, this design can further enhance the stability of the protection mechanism.

[0039] Going further:

[0040] In an optional embodiment, it further includes a protection component 3 provided on the surface of the two vertical plates 24;

[0041] The protection component 3 includes a protection plate 32 slidably connected to the surface of one of the vertical plates 24, the surface of the protection plate 32 is fixedly connected to the limiting block 33, and the surface of the limiting block 33 is slidably connected to the limiting rod 34, the limiting rod 34 is fixedly connected to the surface of the vertical plate 24 near the limiting block 33, and the surface of the limiting rod 34 is wrapped with a spring 1 35, the two ends of the spring 1 35 are respectively fixedly connected to the limiting block 33 and the vertical plate 2 24 near the limiting block 33, a slot 31 adapted to the protection plate 32 is provided on the surface of the vertical plate 2 24 away from the limiting block 33, and a handle 36 is fixedly connected to the surface of the protection plate 32.

[0042] In this embodiment: since a protective plate 32 is provided, the staff can pull the handle 36 to disengage the protective plate 32 from the slot 31. During this process, the limit blocks 33 and the limit rods 34 fixed on both sides of the protective plate 32 slide, and the spring 1 35 is stretched. This design can prevent the alarm 1 from being accidentally touched, and can also facilitate the use of the alarm 1.

[0043] Working principle: Since the surface of the alarm 1 is provided with a mounting base 21, when the staff needs to dismantle the vertical plate 1 23 and the vertical plate 24, they can pull the baffle 27. At this time, the baffle 27 drives the spring pin 26 to disengage from the card slot 28, and then the card block 210 connected by rotating the surface of the hinge seat 29 is inserted into the card slot 28, so that the vertical plate 1 23 and the vertical plate 24 are separated from the mounting base 21. With this design, it is convenient for the staff to repair the alarm 1. Since the surface of the mounting base 21 is provided with a mounting plate 22, with this design, the staff can repair the alarm 1 conveniently. The operator can install the mounting plate 22 on the wall surface through the threaded bolts provided on the surface of the mounting plate 22. Since the bolts 211 are provided, this design can further enhance the stability of the protection mechanism. Since a protection plate 32 is provided, the operator can pull the handle 36 to disengage the protection plate 32 from the slot 31. During this process, the limit blocks 33 and limit rods 34 fixed on both sides of the protection plate 32 slide and cause the spring 1 35 to stretch. This design can prevent the alarm 1 from being accidentally triggered while also making it convenient to use the alarm 1.

[0044] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
