Description

Technical Field

[0001] The utility model belongs to the technical field of fireproof doors, and in particular relates to a weld-point-free reinforced fireproof door. Background Art

[0002] Fire doors are doors that meet fire resistance, stability, integrity, and thermal insulation requirements for a specified period of time. Installed between fire compartments, evacuation stairwells, vertical shafts, and other locations, these fireproof partitions offer a certain degree of fire resistance and prevent the spread of fire and smoke, effectively preventing the spread of fire and ensuring evacuation. Fire doors are a crucial component of firefighting equipment and a crucial part of fire prevention.

[0003] For example, Patent No. CN214330438U discloses a weld-free reinforced fire door, which includes a door panel, a frame, and a core material that matches the shape of the frame. The frame includes two sets of vertically arranged single frames and two sets of horizontally arranged double frames. The two adjacent sets of single frames and double frames are arranged vertically. The two sets of double frames, arranged vertically, have circular holes at both ends. Each set of circular holes has a screw inserted into the inner portion of the screw hole that is threadedly connected to the single frame. The core material is a polyurethane foam board, which is inserted into the square area enclosed by the four sets of frames. This application eliminates the welding process and adopts a more efficient screw connection method, thereby improving the labor efficiency and reducing the labor intensity of fire door manufacturers.

[0004] In the prior art, by setting one frame and two frames and using threaded connections instead of welding, the working time of the staff is saved and the working efficiency of the staff is improved. However, the following problems still exist during the overall use process: First, the existing fire doors without weld points have poor explosion-proof effect. After the fire door is impacted, the supporting frame is easily deformed and the stability effect is poor; secondly, when the existing fire door encounters a fire, the fireproof strips will be deformed and fall off due to the temperature of the metal door frame or direct contact with the external fire source, thereby causing the sealing effect of the fire door to deteriorate, and thick smoke will spread to other areas through the door gap, causing harm to escaping personnel. Utility Model Content

[0005] In order to overcome the deficiencies of the prior art, the present invention provides a weld-free reinforced fire door. By arranging a buffer plate, the buffer plate can be brought into contact with an external support frame. When impacted, the cooperation of the buffer plate and the connecting rod can provide a buffer for the external support frame, thereby improving the stability of the external support frame. By arranging a partition block and a fireproof component, the sealing strip can be isolated to prevent it from direct contact with the fire source, thereby improving the sealing performance of the fire door.

[0006] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a weld-free reinforced fire door, comprising a left mounting frame, a top mounting frame and a right mounting frame, characterized in that a right mounting frame is provided on one side of the left mounting frame, a top mounting frame is provided on the top of the right mounting frame and the left mounting frame, an external support frame is provided on the bottom of the top mounting frame, a door frame is provided on one side of the external support frame, a cross beam is provided inside the door frame, a buffer plate is slidably provided on one side of the cross beam, the buffer plate abuts against the end face of the external support frame, a partition block is provided on one side of the door frame, and a fireproof component is provided inside the partition block.

DETAILED DESCRIPTION

[0025] In order to enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Example 1:

[0026] refer to Figure 1 and Figure 2 A weld-free reinforced fire door includes a left mounting frame 1, a top mounting frame 2, and a right mounting frame 3. The right mounting frame 3 is provided on one side of the left mounting frame 1, the top mounting frame 2 is provided on the top of the right mounting frame 3, and the external support frame 4 is provided on the bottom of the top mounting frame 2. A door frame 10 is provided on one side of the external support frame 4, and a cross beam 11 is provided inside the door frame 10. A buffer plate 16 is slidingly provided on one side of the cross beam 11, and the buffer plate 16 abuts on the end surface of the external support frame 4. A partition block 20 is provided on one side of the door frame 10, and a fireproof component is provided inside the partition block 20.

[0027] In this solution, the bottom of the top mounting frame 2 is stepped. This setting is to cooperate with the fireproof door panel 32 to achieve a better sealing effect. A rotating connector that cooperates with the mounting connector 7 is provided on one side of the left mounting frame 1, so that the door frame 10 is rotatably connected to the left mounting frame 1. A fixing groove is provided on the surface of the door frame 10, and the fixing member 9 fixes the crossbeam 11 inside the door frame 10 through the fixing groove, and makes the surface of the door frame 10 flat.

[0028] refer to Figure 3 A light rod 12 is provided inside the crossbeam 11, and a plurality of moving blocks 13 are slidingly provided on the outer surface of the light rod 12. A shock-absorbing spring 14 is provided in the middle of the two moving blocks 13. A connecting rod 15 is rotatably provided on one side of the moving block 13. The connecting rod 15 is rotatably connected to the buffer plate 16. A positioning block 18 is provided on one side of the buffer plate 16 on the inner wall of the door frame 10, and the buffer plate 16 is slidably connected to the inside of the positioning block 18.

[0029] In this solution, a slide groove is provided inside the positioning block 18, and raised parts are provided at both ends of the buffer plate 16. The raised parts are slidably connected in the slide groove, so that the positioning block 18 plays a limiting support role for the buffer plate 16. After the external support frame 4 is subjected to the impact of the explosion, the buffer plate 16 on one side will be squeezed. The buffer plate 16 drives the connecting rod 15 to squeeze the first return spring 24, so that the first return spring 24 plays a buffering role, which can effectively improve the stability of the external support frame 4.

[0030] refer to Figure 4 , Figure 5 and Figure 6The fireproof component includes a mounting groove 19 arranged inside the partition block 20, a movable block 21 is slidingly arranged inside the mounting groove 19, a guide rod 22 is arranged at the bottom of the movable block 21, a fixed block 23 is arranged outside the guide rod 22, and a first return spring 24 is arranged on the end face of the fixed block 23 on the outside of the guide rod 22, and an inclined block 25 is arranged at the bottom of the guide rod 22. A sliding transmission block 26 is provided inside the inclined block 25, and a roller 27 is provided at one end of the transmission block 26. The roller 27 abuts on the end face of the inclined block 25, and a fireproof plate 28 is provided at one end of the transmission block 26. A sealing strip 29 is provided on one side of the fireproof plate 28 on one side of the partition block 20, and a second return spring 33 is provided on the end face of the fireproof plate 28, and one end of the second return spring 33 is connected to the inner wall of the mounting groove 19.

[0031] In this solution, an inclined groove is provided inside the fixed block 23, and the movable block 21 slides up and down in the mounting groove 19, but will not fall off the upper part of the mounting groove 19. When closing the door, the top mounting frame 2 will squeeze the inclined surface of the movable block 21, causing the movable block 21 to slide downward and squeeze the first return spring 24. At the same time, the movable block 21 will drive the guide rod 22 to move downward, and the guide rod 22 will drive the fixed block 23 to move downward. The inclined surface inside the fixed block 23 will squeeze the roller 27 and push the roller 27 to move horizontally. The roller 27 drives the fireproof plate 28 to move through the transmission block 26, so that the fireproof plate 28 abuts against the surface of the right mounting frame 3, blocking the front of the sealing strip 29, to prevent the sealing strip 29 from direct contact with the fire source.

[0032] refer to Figure 7 and Figure 8 A mounting connector 7 is provided on one side of the door frame 10, and the mounting connector 7 is rotatably connected to the left mounting frame 1. A fixing part 9 is provided on one side of the door frame 10, and a door handle 5 is provided on the end face of the external support frame 4. A fire-resistant board 6 is provided inside the door frame 10, and a reinforcement plate 30 is provided on one side of the fire-resistant board 6. A sound insulation sponge 31 is provided on one side of the reinforcement plate 30. A fireproof door panel 32 is provided on one side of the door frame 10, and the sound insulation sponge 31 abuts against the end face of the fireproof door panel 32.

[0033] In this solution, the mounting connector 7 is rotatably connected to the rotating connector on the surface of the left mounting frame 1, so that the door frame 10 can be opened and closed normally. The fixing member 9 fixes the positioning block 18 and the crossbeam 11 inside the door frame 10, reducing the welding time and improving the work efficiency of the workers. The door handle 5 and the corresponding door lock are existing technologies, and this solution will not elaborate on them in detail. Their main function is to lock the door frame 10, wherein the area of the fireproof door panel 32 is larger than the area of the door frame 10, so that the intersection of the fireproof door panel 32 and the door frame 10 forms a stepped shape, which cooperates with the top mounting frame 2 to improve the sealing effect of the fireproof door. By setting the sound insulation sponge 31, the noise can be reduced and the practicality of the fireproof door can be improved. By setting the reinforcement plate 30, the cavity formed by the door frame 10 can be filled to improve the stability of the fireproof door.

[0034] When a fire occurs, if an explosion occurs, the impact force of the explosion will be transmitted to the external support frame 4. When the external support frame 4 is impacted by the explosion, it will squeeze the buffer plate 16 on one side. The buffer plate 16 drives the connecting rod 15 to squeeze the first return spring 24, so that the first return spring 24 plays a buffering role, which can effectively improve the stability of the external support frame 4.

[0035] When closing the fire door, the top mounting frame 2 will squeeze the inclined surface of the movable block 21, causing the movable block 21 to slide downward and squeeze the first return spring 24. At the same time, the movable block 21 will drive the guide rod 22 to move downward, and the guide rod 22 will drive the fixed block 23 to move downward. The inclined surface inside the fixed block 23 will squeeze the roller 27 and push the roller 27 to move horizontally. The roller 27 drives the fireproof plate 28 to move through the transmission block 26, so that the fireproof plate 28 abuts against the surface of the right mounting frame 3 and blocks the front of the sealing strip 29, avoiding direct contact between the sealing strip 29 and the fire source, thereby improving the service life of the fire door.
