Description

Technical Field

[0001] This utility model relates to the field of fire door technology, specifically a wooden fire door. Background Technology

[0002] Wooden fire doors play an important role in the construction industry. They are mainly used to isolate fire sources and effectively block the spread of fire, protecting people's lives and property. However, fires produce a lot of smoke, so the design of wooden fire doors must take into account the requirements for personnel evacuation and smoke prevention.

[0003] The prior art, disclosed in CN221373375U, provides a combined fireproof structure for a wooden fire door, relating to the field of fire doors. It includes a fire door frame, a fire door body movably installed within the frame, a door handle fixedly installed at the edge of the fire door body, an inlet / outlet hole in the middle of the fire door body, a sealing mechanism at the bottom of the fire door body, a sealing baffle movably installed at the bottom of the fire door body, a limiting support fixedly installed in the middle of the sealing baffle, a limiting hole at the upper edge of the limiting support, a guide rod fixedly installed in the middle of the sealing baffle, a return spring sleeved on the guide rod, and a limiting mechanism within the inlet / outlet hole. A heat-absorbing metal plate absorbs heat and transfers it to the metal sleeve, causing the plastic limiting rod to melt. Once the plastic limiting rod melts, the limiting support loses its obstruction, and the return spring pushes the sealing baffle downwards to block the gap at the bottom of the fire door, preventing the free flow of dense smoke.

[0004] The aforementioned patent mainly uses the cooperation of a limiting structure and a spring structure to block the gap at the bottom of the fire door with a sealing baffle. However, this method of sealing the bottom of the fire door relies on damaging the limiting structure. This can lead to the bottom of the fire door being blocked for a long time if the limiting structure is accidentally melted by high temperatures. Reinstalling the spring structure is also quite complicated, which greatly reduces the overall practicality of the combined fireproof structure of the wooden fire door. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a wooden fireproof door that solves the above-mentioned technical problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A wooden fire door includes a door frame, within which a fire door body is rotatably mounted. A temperature sensor for temperature detection is fixedly mounted on one side of the fire door body, and an electric controller for powering and driving the temperature sensor is fixedly mounted on the side of the fire door body away from the temperature sensor. The electric controller is electrically connected to the temperature sensor. The fire door body includes a wooden wall with an inner groove. An electric push rod is fixedly mounted at the top of the inner groove and is electrically connected to the electric controller. A sealing component for sealing the bottom of the door frame is fixedly mounted on the telescopic end of the electric push rod. The telescopic end of the electric push rod, with its sealing component, allows the sealing component to be moved directly with the extension of the electric push rod, thus facilitating the sealing of the bottom of the wooden fire door and greatly improving its usability.

[0007] Furthermore, a transmission assembly is fixedly installed on the wooden wall. This transmission assembly drives the sealing assembly to move within the inner groove. The sealing assembly includes a movable plate fixed to the telescopic end of the electric actuator. Multiple toothed holes are formed on the side of the movable plate near the transmission assembly, and the transmission assembly meshes with the movable plate. This meshing of the transmission assembly and the movable plate allows the movable plate to move along with the transmission assembly as it rotates, improving the overall integrity of the internal structure of the wooden fire door.

[0008] Furthermore, the transmission assembly includes a fixed plate fixedly mounted on the wooden wall, a rotatable handle rotatably mounted at the center of the fixed plate, and a gear fixedly mounted at the tail end of the rotatable handle, the gear engaging with the toothed hole.

[0009] Furthermore, an alarm is fixedly mounted on the side of the fire door body near the temperature sensor, and the alarm is electrically connected to the live controller. This electrical connection allows the live controller to directly control the alarm, significantly enhancing the intelligence of the internal structure of the wooden fire door.

[0010] Furthermore, a rectangular groove is formed at the end of the movable plate away from the electric actuator. An elastic element is fixedly connected to the movable plate within this rectangular groove. The elastic element is used to further seal the bottom of the door frame. This further seals the bottom of the door frame, improving the sealing performance of the elastic element at the bottom of the door frame.

[0011] Furthermore, the elastic element is made of rubber. The rubber material improves the sealing performance of the elastic element at the bottom of the door frame.

[0012] Furthermore, the movable panel is T-shaped. This T-shape reduces the size of the internal groove in the wooden wall, improving the energy efficiency of the wooden fire door. Beneficial effects

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This invention features an electric push rod fixedly installed on the top of the sealing assembly, which, in conjunction with a rotatable gear meshing on one side of the sealing assembly, allows the sealing assembly to move downwards to seal the bottom of the wooden fire door when the user needs to seal it, both automatically and manually. The sealing assembly can also automatically move upwards, greatly improving the practicality of the wooden fire door. Attached Figure Description

[0021] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0022] Example

[0023] The following is in conjunction with the appendix Figure 1 - Appendix Figure 5This application will be further described in detail below. A wooden fire door includes a door frame 1, a fire door body 2 rotatably mounted inside the door frame 1, a temperature sensor 3 for temperature detection fixedly mounted on one side of the fire door body 2, and an electric controller 5 for powering and driving the temperature sensor 3 fixedly mounted on the side of the fire door body 2 away from the temperature sensor 3. The electric controller 5 is electrically connected to the temperature sensor 3. The fire door body 2 includes a wooden wall 22, an inner groove 24 is formed inside the wooden wall 22, an electric push rod 21 is fixedly mounted on the top of the inner groove 24, the electric push rod 21 is electrically connected to the electric controller 5, a sealing component 25 for sealing the bottom of the door frame 1 is fixedly mounted on the telescopic end of the electric push rod 21, and a transmission component 23 is fixedly mounted on the wooden wall 22. The transmission component 23 is used to drive the sealing component 25 to move in the inner groove 24. The sealing component 25 includes components fixed to the electric push rod 21. The movable plate 252 on the telescopic end of the rod 21 has multiple toothed holes 251 on the side of the movable plate 252 near the transmission component 23. The transmission component 23 meshes with the movable plate 252. The transmission component 23 includes a fixed plate 232 fixedly installed on the wooden wall 22. A handle 231 is rotatably installed at the center of the fixed plate 232. A gear 233 is fixedly installed at the tail end of the handle 231. The gear 233 cooperates with the toothed holes 251. The fire door body 2 is fixedly installed with an alarm 4 on the side near the temperature sensor 3. The alarm 4 is electrically connected to the live controller 5. A rectangular groove is opened at the end of the movable plate 252 away from the electric push rod 21. An elastic element 253 is fixedly connected in the rectangular groove of the movable plate 252. The elastic element 253 is used to further seal the bottom of the door frame 1. The elastic element 253 is made of rubber. The movable plate 252 is T-shaped.

[0024] Among them, the electric actuator 21 is model XDHA24-500. With its advantages of silent gears, stable base and low resistance metal shell, the electric actuator 21 can operate in wooden fire doors for a longer period of time. The electric actuator 21 can self-lock when it is powered on and is in a non-self-locking state when it is not powered on. Therefore, when the electric actuator 21 is not powered on, the user can rotate the handle 231 to rotate the gear 233, which will move the movable plate 252 up and down through the tooth hole 251.

[0025] The live controller 5 contains a power supply and an Arduino control board. The Arduino control board is electrically connected to the electric push rod 21, the temperature sensor 3, and the alarm 4. Therefore, when the temperature sensor 3 detects that the outside temperature is higher than the set value, the temperature sensor 3 will transmit an electrical signal to the Arduino control board. The Arduino control board will then activate the alarm 4 to sound an alarm, alerting people outside that a fire has occurred. At the same time, the Arduino control board will trigger the electric push rod 21 to move the sealing component 25 downwards, causing the sealing component 25 to seal the bottom of the wooden fire door, preventing smoke from passing through the wooden fire door.

[0026] Since the elastic element 253 is made of rubber, when the movable plate 252 moves downward, the elasticity of the rubber material allows the entire sealing assembly 25 to fit the floor more closely, thereby further improving the sealing performance of the wooden fire door and further reducing the amount of smoke passing through the wooden fire door.

[0027] The working principle of this utility model is explained below: Unless otherwise specified, all internal mechanical structures of the wooden fire door are fixed by threads. To allow for a more intuitive observation of the technical features, bolt connections are appropriately concealed in the diagram. During use, the bottom of the wooden fire door is kept open for extended periods of ventilation. When a fire occurs around the wooden fire door, the heat generated by the fire is directly sensed by the temperature sensor 3. When the heat detected by the temperature sensor 3 exceeds a set value, the electrical controller 5 controls the alarm 4 to sound an alarm and causes the electric push rod 21 to move downwards, carrying the sealing assembly 25, thereby closing the bottom of the wooden fire door. Effective sealing is achieved. When the temperature sensor 3 causes the sealing component 25 to move downward due to false temperature detection, the user can directly control the electric actuator 21 to move the sealing component 25 upward by controlling the energized controller 5, or rotate the handle 231 to rotate the gear 233. At this time, the electric actuator 21 needs to be in a de-energized state. The rotation of the gear 233 will directly move the movable plate 252 upward through the tooth hole 251. This allows the sealing component 25 to be moved manually or automatically when the wooden fire door is in use, greatly improving the practicality of the wooden fire door.

[0028] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
