Technical Field

[0001] This utility model relates to the field of fire door technology, specifically to a steel fire door that is easy to install. Background Technology

[0002] Steel fire doors refer to doors with a specified fire resistance performance, consisting of a door frame, door leaf skeleton, and door leaf panel made of steel materials. If the door leaf is filled with materials, it is filled with fireproof and heat-insulating materials that are non-toxic and harmless to the human body, and equipped with fireproof hardware accessories. Steel fire doors are usually composed of a door frame, connecting skeleton, and door panel. During installation, the door frame and connecting skeleton usually need to be installed and connected.

[0003] However, there are still some problems with the installation of existing steel fire doors:

[0004] Firstly, fire doors are generally installed using hinges, but traditional hinges are pre-connected, which reduces the ease of fire door installation due to their lack of flexibility.

[0005] Secondly, the existing fire door structure lacks an effective auxiliary positioning structure during installation, often requiring workers to manually support the fire door to align it in place. This not only increases manpower input but also raises the installation cost of the fire door. Utility Model Content

[0006] To address the issues of poor installation flexibility and lack of effective auxiliary positioning structures in existing fire door installation structures, the purpose of this utility model is to provide a steel fire door that is easy to install.

[0019] 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.

[0020] Example: Figure 1-5 As shown, this utility model provides a steel fire door that is easy to install, including a door frame body 1. The fire door body 4 is provided inside the door frame body 1. An auxiliary positioning component 3 is provided on one side of the door frame body 1 to cooperate with the fire door body 4. The auxiliary positioning component 3 is used in conjunction with the fire door body 4 to help determine the position of the fire door body 4 during installation, thereby improving installation accuracy. A first hinge body 6 is provided parallel to one side of the door frame body 1. The first hinge body 6 is fixedly connected to the door frame body 1 by bolts. A second hinge body 5 is provided parallel to one side of the fire door body 4. The second hinge body 5 is fixedly connected to the fire door body 4 by bolts. The first hinge body 6 is fixed to the door frame body 1 by bolts, and the second hinge body 5 is fixed to the fire door body 4 by bolts. This split installation method is more flexible in installation than the traditional pre-connected integral hinge.

[0021] Correspondingly, a connecting component 2 is provided between the first hinge body 6 and the second hinge body 5. There are three connecting components 2, and the internal structure of the three connecting components 2 is the same. The three connecting components 2 with the same structure can stably connect the first hinge body 6 and the second hinge body 5, improving the flexibility of fire door installation.

[0022] The connecting component 2 includes a first post sleeve 21 arranged in parallel. The first post sleeve 21 is fixedly installed on one side of the first hinge body 6. A second post sleeve 23 is fixedly connected in parallel to one side of the second hinge body 5. Correspondingly, the first post sleeve 21 and the second post sleeve 23 are arranged alternately. The first post sleeve 21 is fixed on the first hinge body 6, and the second post sleeve 23 is fixed on the second hinge body 5. The two are arranged alternately to provide an accurate insertion position for the positioning pin 22.

[0023] A positioning pin 22 is movably inserted into both the first and second column sleeves 21 and 23, achieving a preliminary connection between the first hinge body 6 and the second hinge body 5. A positioning sleeve 26 is movably fitted onto the top of the positioning pin 22. The positioning sleeve 26 and the positioning pin 22 are threadedly connected to a locking screw 24. The outer surfaces of the positioning sleeve 26 and the positioning pin 22 are respectively provided with a first screw hole 25 and a second screw hole 27 for use with the locking screw 24. The locking screw 24 is threadedly connected to the first screw hole 25 and the second screw hole 27. The positioning sleeve 26 is fitted onto the top of the positioning pin 22, and the locking screw 24 is threadedly connected to the first screw hole 25 and the second screw hole 27 on the positioning sleeve 26 and the positioning pin 22. After installation, this further tightens the connection between the first hinge body 6 and the second hinge body 5, preventing the positioning pin 22 from loosening during use. This split installation method improves the flexibility and convenience of fire door installation.

[0024] The auxiliary positioning component 3 includes a slot 31, which is located on one side of the door frame body 1. A positioning plate 33 is movably engaged in the slot 31. A protruding strip on the positioning plate 33 can control the gap between the fire door body 4 and the door frame body 1 during installation.

[0025] The positioning plate 33 and the slot 31 are movably connected to a vertical rod 35. A vertical groove 36 is provided on one side of the door frame body 1 to cooperate with the vertical rod 35. The vertical rod 35 is slidably connected to the vertical groove 36. A through groove 34 is provided on one side of the upper surface of the positioning plate 33 to cooperate with the vertical rod 35. A groove 32 is provided in the slot 31 to cooperate with the vertical rod 35. The vertical rod 35 is movably connected to the through groove 34 and the groove 32. The vertical rod 35 passes through the through groove 34 and the groove 32 in sequence and is slidably connected to the vertical groove 36 on one side of the door frame body 1. This can stably fix the positioning plate 33, ensure the stability of the auxiliary positioning, and thus effectively reduce the cost of fire door installation.

[0026] Working principle: First, the positioning plate 33 is inserted into the slot 31 by the auxiliary positioning component 3, and the vertical rod 35 passes through the through slot 34 and the groove 32 in sequence and slides in the vertical slot 36 to fix the positioning plate 33 in a suitable position. In this way, the positioning plate 33 can control the gap between the fire door body 4 and the door frame body 1.

[0027] Then, the first hinge body 6 and the second hinge body 5 are installed on the fire door body 4 and the door frame body 1 at appropriate positions by means of bolt connection.

[0028] Next, place the fire door body 4 that needs to be installed against the positioning plate 33 to ensure that the fire door body 4 can be accurately installed inside the door frame body 1.

[0029] Next, by connecting component 2, the positioning pin 22 is inserted into the staggered first post sleeve 21 and second post sleeve 23 to initially position the first hinge body 6 and the second hinge body 5.

[0030] Then, the positioning sleeve 26 is placed on the top of the positioning pin 22, and the locking screw 24 is tightened to make it fit tightly with the first screw hole 25 and the second screw hole 27, thereby firmly fixing the positioning pin 22 inside the first column sleeve 21 and the second column sleeve 23, realizing a stable connection between the first hinge body 6 and the second hinge body 5, realizing a split installation, and thus improving the installation convenience of the entire fire door.

[0031] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
