[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0025] Reference Figure 1 and Figure 2 The utility model provides an embodiment: a highly flame-retardant wooden fireproof door, comprising a door frame 1, a top shell 5 is fixedly connected to the top of the door frame 1, a flap 14 is rotatably connected to the bottom end of the top shell 5, and fixed brackets 13 are fixedly connected to the top two sides of the flap 14, and the two fixed brackets 13 are connected to a sleeve rod 11 through an installation assembly, and a rolled-up fireproof cloth 2 is arranged on the outer wall of the sleeve rod 11, and a plurality of hooks 12 are sleeved on one side of the fireproof cloth 2, and the hooks 12 are sleeved with the sleeve rod 11, and before the sleeve rod 11 is fixed, the hooks 12 are sleeved on the sleeve rod 11 first, so as to realize the fixed installation of the fireproof cloth 2, and the installed fireproof cloth 2 is rolled up from bottom to top and placed inside the top shell 5, and the rolled-up fireproof cloth 2 is placed inside the top shell 5 by using an electromagnetic lock, and the fireproof door 7 is rotatably connected to both sides of the interior of the door frame 1;
[0026] Among them, reference Figure 4 The mounting assembly includes a fixing knob 10 threadedly connected to two ends of a sleeve rod 11, and two ends of the sleeve rod 11 are sleeved with a fixing bracket 13;
[0027] Specifically, after the sleeve rod 11 passes through the middle through hole of the fixing bracket 13, the fixing knob 10 is rotated so that the fixing knob 10 is at both ends of the sleeve rod 11 until the fixing knob 10 is in contact with the fixing bracket 13, thereby fixing the sleeve rod 11 on the flap 14. Before fixing the sleeve rod 11, the hook 12 is first put on the sleeve rod 11, so as to fix the fire isolation cloth 2. After the installation, the fire isolation cloth 2 is rolled up from bottom to top and placed inside the top shell 5. The rolled up fire isolation cloth 2 is placed inside the top shell 5 using an electromagnetic lock.
[0028] Reference Figure 5The bottom end of the fireproof cloth 2 is fixedly connected with a counterweight magnet 15, and one side of the door frame 1 is attracted to the counterweight magnet 15, so that the fireproof cloth 2 falling under gravity is attracted to the door frame 1 at one end of its bottom, so as to be fixed; a through groove 3 is provided inside the fireproof cloth 2, and transparent glue is fixed inside the through groove 3; door locks are provided on both sides of one side of the fire door 7, and an observation window 6 is provided inside the fireproof door 7. The fireproof cloth 2 is made of four layers of fireproof cloth, namely: the outer layer is aramid fireproof clothing fabric, the second layer is aramid aluminum foil cloth, the third layer is aramid pre-oxidized fiber quilted blanket, and the inner layer is aramid firefighting clothing fabric.
[0029] Reference Figure 3 A door closer 9 is fixedly connected to the top of the door frame 1, and the bottom end of the door closer 9 is connected to the fire door 7 through a connecting rod 8; the setting of the door closer 9 allows the door to be automatically closed by being compressed and released after being opened, and acts like a spring door, which can ensure that the door is accurately and timely closed to the initial position after being opened. A magnetic lock 4 is provided on the top of the flap 14 and the top shell 5, and the magnetic lock 4 is connected through a temperature sensor, wherein the temperature sensor adopts a thermistor, which detects the ambient temperature and converts it into an electrical signal to realize the activation of the magnetic lock 4, thereby realizing the automatic opening and closing of the flap 14.
[0030] Working principle: first, after the sleeve rod 11 passes through the middle through hole of the fixing bracket 13, the fixing knob 10 is rotated so that the fixing knob 10 is at both ends of the sleeve rod 11 until the fixing knob 10 is in contact with the fixing bracket 13, thereby fixing the sleeve rod 11 on the flap 14. Before fixing the sleeve rod 11, the hook 12 is first put on the sleeve rod 11, so as to achieve the fixed installation of the fireproof cloth 2. After the installation, the fireproof cloth 2 is rolled up from bottom to top and placed inside the top shell 5. The rolled-up fireproof cloth 2 is placed inside the top shell 5 by using an electromagnetic lock. The ambient temperature is detected by a temperature sensor. When high temperature is detected, it is converted into an electrical signal to start the magnetic lock 4, so that the flap 14 is folded downward under gravity. At this time, the fireproof cloth 2 rolled up inside the top shell 5 rotates downward and unfolds under gravity. Finally, under inertia, it is attracted with the door frame 1 to achieve fixation, thereby achieving further wrapping and protection of the fire door 7, thereby achieving a fireproof effect.
[0031] Finally, it should be noted that the above is only 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 can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
