[0002] In densely populated buildings, a large number of fire protection facilities are usually installed to take corresponding measures in the event of a fire, reducing casualties and property losses. These fire protection facilities include steel fire doors. As one of the fire-resistant partitioning measures in buildings, steel fire doors are usually used at the entrances and exits of stairwells or pipe shafts. They are required to be able to block smoke and fire. Fire doors play an important role in preventing the spread and propagation of smoke and fire and reducing losses.

[0003] Patent document CN222615184U discloses a steel door with an automatic alarm function, including a door frame. The door is characterized by a steel door hinged to the inside of the door frame, a smoke detector on the surface of the steel door, an escape door hinged to the inside of the steel door, and a drive assembly inside the steel door. The smoke detector is triggered by smoke from combustion, emitting an alarm sound to alert people inside the building. In implementing this technical solution, the inventors discovered at least the following problems in the prior art: During use, the aforementioned steel door can be used to trigger a fire alarm via a smoke detector. However, the smoke sensor is directly fixed to the steel door and is not easy to remove, making it inconvenient to repair or replace the smoke detector later. Furthermore, the smoke sensor lacks protection and cannot effectively prevent small insects and larger dust particles from entering the photoelectric labyrinth of the smoke sensor. Insects can easily clog the sampling channel of the smoke sensor or interfere with the sensitivity of the optical sensor. Utility Model Content

[0019] Furthermore, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0020] Please see Figures 1-5 As shown in the figure, the present invention provides a steel door with an automatic alarm function, including a steel door body 1, a mounting base 2 fixedly installed on one side of the steel door body 1, a mounting component 3 installed inside the mounting base 2, a protective cover 4 fixedly connected to one side of the mounting base 2, a smoke detector 5 installed on one side of the mounting base 2, the smoke detector 5 being located inside the protective cover 4, a filter screen 6 installed inside the protective cover 4, and a pair of fixing blocks 7 fixedly connected to the mounting base 2.

[0021] The smoke detector 5 on one side of the steel door body 1 automatically alarms in case of fire. The smoke produced by the fire will trigger the smoke detector 5, causing it to sound an alarm to alert people inside the building. The smoke detector 5 is installed on one side of the mounting base 2 via the mounting component 3, which facilitates the installation and removal of the smoke detector 5 and makes it easy to inspect and maintain. The protective cover 4 and the filter screen 6 can block mosquitoes and small insects, preventing them from damaging the alarm system inside the smoke detector 5 during normal use.

[0022] Preferably, the mounting assembly 3 includes a first spring 31 disposed at the bottom of the inner cavity of the mounting base 2, a wedge block 32 disposed at the top of the first spring 31, and a moving rod 33 slidably disposed on the inclined surfaces on both sides of the wedge block 32. A second spring 34 is disposed on both sides of the inner wall of the mounting base 2. One end of the second spring 34 is fixedly engaged with one side of the moving rod 33. A pressing block 35 is fixedly connected to the top of the wedge block 32. The pressing block 35 movably passes through the mounting base 2 and extends to the outside of the mounting base 2. A moving groove 36 is opened inside the mounting base 2 to cooperate with the moving rod 33. An insert block 37 is fixedly connected to the bottom of the moving rod 33 and is inserted into the reserved groove 8.

[0023] Mounting base 2 is fixedly installed on the steel door body 1 by fixing block 7. Manually pressing down on pressing block 35 causes wedge block 32 to move downwards, compressing the first spring 31. As wedge block 32 moves downwards, one side of each of the two moving rods 33 slides on the inclined surfaces of the wedge block 32. As the width of wedge block 32 changes, the two moving rods 33 move towards each other under the elastic action of the second spring 34. The moving rods 33 then cause the two insert blocks 37 to move towards each other, completing the first step. Next, the smoke alarm 5 is installed on mounting base 2. Two insert blocks 37 are inserted into the reserved slots 8 at the top of the smoke alarm 5. The pressing block 35 is released, and the wedge block 32 returns to its initial position under the elastic action of the first spring 31. The two moving rods 33 return to their initial positions under the influence of the width change of the wedge block 32 and the elastic action of the second spring 34, so that the two insert blocks 37 are inserted into the L-shaped reserved slots 8, and the smoke alarm 5 is connected and fixed. Thus, only the pressing block 35 needs to be controlled to move the two insert blocks 37 in the reserved slots 8, which facilitates quick installation and disassembly.

[0024] It should be noted that the spring force coefficient of the first spring 31 is greater than that of the second spring 34, so as to prioritize the reset function of the pressing block 35 and avoid the pressing block 35 being obstructed by the spring force of the second spring 34 when resetting.

[0025] Preferably, the filter screen 6 is fixedly connected to the insert rods 9 on both sides, and the inner wall of the protective cover 4 is provided with slots 10 on both sides for use with the insert rods 9.

[0026] The filter screen 6 is inserted into the slot 10 on the inner wall of the protective cover 4 via the insert rods 9 on both sides, which facilitates the installation and removal of the filter screen 6 and makes it easy to clean the filter screen 6.

[0027] Preferably, a viewing window 11 is provided on one side of the steel door body 1, and handles 12 are provided on both sides of the steel door body 1.

[0028] The viewing window 11 allows people outside the steel door body 1 to observe the fire situation inside, and the handle 12 facilitates the opening and closing of the steel door body 1.

[0029] The working principle of this utility model is as follows: A smoke detector 5 on one side of the steel door body 1 automatically triggers a fire alarm. Smoke generated during combustion will activate the smoke detector 5, causing it to sound an alarm and alert people inside the building. The mounting base 2 is fixedly installed on the steel door body 1 via a fixing block 7. Manually pressing down the pressing block 35 causes the wedge block 32 to move downwards, compressing the first spring 31. As the wedge block 32 moves downwards, one side of each of the two moving rods 33 slides on the inclined surfaces on both sides of the wedge block 32. As the width of the wedge block 32 changes, the two moving rods 33 move towards each other under the elastic action of the second spring 34. The moving rods 33 then cause the two insert blocks 37 to move towards each other, thus completing the first step. Next, the smoke detector 5 is installed... Installed on mounting base 2, the two insert blocks 37 are inserted into the reserved slots 8 at the top of the smoke alarm 5. Releasing the pressing block 35 allows the wedge block 32 to return to its initial position under the elastic action of the first spring 31. The two moving rods 33, affected by the width change of the wedge block 32 and the elastic action of the second spring 34, return to their initial positions, allowing the two insert blocks 37 to be inserted into the L-shaped reserved slots 8, thus connecting and fixing the smoke alarm 5. This achieves the goal of moving the two insert blocks 37 within the reserved slots 8 simply by controlling the pressing block 35, facilitating quick installation and disassembly. The protective cover 4 and filter screen 6 can block mosquitoes and small insects, preventing damage to the internal alarm system of the smoke alarm 5 during normal use.

[0030] It should be understood that numerous specific implementation decisions can be made during the development of any practical implementation, such as in any engineering or design project. Such development efforts may be complex and time-consuming, but for those skilled in the art who benefit from this disclosure, the development effort will be a routine work of design, manufacturing, and production without requiring much experimentation.

[0031] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
