Description

Technical Field

[0001] This utility model belongs to the field of emergency door technology, specifically relating to an emergency evacuation door. Background Technology

[0002] Evacuation doors are emergency evacuation doors with good sealing performance. They are typically used in fire prevention, smoke prevention, or special safety scenarios. They can be opened quickly in emergencies to ensure the safe evacuation of personnel and possess protective properties: they may also have fire resistance (such as Class A fire doors), explosion-proof, or sound insulation characteristics. Evacuation doors are mainly used in large public places such as stadiums, cinemas, train stations, airport waiting halls, and large office buildings. They are vital passageways for people to evacuate to safe areas during emergencies.

[0003] In the prior art, such as the emergency evacuation door and vehicle with application number 202121429498.5, the emergency evacuation door is installed on the vehicle body and includes a mechanical locking structure, an electromagnetic locking structure and a door body. The mechanical locking structure and the electromagnetic locking structure can lock the door body in a closed state respectively. The mechanical locking structure includes a control unit. When the mechanical locking structure is unlocked, the control unit can send an unlocking request to the control center. The control center can send a zero-speed signal and an unlocking signal to the electromagnetic locking structure.

[0004] The dual locking mechanism of mechanical and electromagnetic locking makes unlocking and pushing the door safer, which reflects the door's security to a certain extent. However, after reading the technical solution, it is found that the maximum opening angle of the door is limited, and the opening area is also limited. In emergency evacuation situations, this kind of door with a fixed opening area is not practical, which in turn affects the normal evacuation of personnel. Utility Model Content

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments 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. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] This utility model embodiment provides an emergency evacuation door, including a door frame 1; for example, such as... Figures 1-3 As shown.

[0023] The door frame 1 is equipped with a push-pull assembly 2, which includes a hinged base panel 21. A curved path 24 is provided on the side of the hinged base panel 21. A pulley 25 is slidably connected to the inner cavity of the curved path 24. A hinged sliding panel 22 is mounted on the end face of the pulley 25. Through the sliding connection between the pulley 25 and the curved path 24, the hinged sliding panel 22 can symmetrically move along the surface of the hinged base panel 21, significantly expanding the evacuation area and facilitating rapid evacuation of personnel. The hinged sliding panel 22 is equipped with an inward-retracting component 26, and a claw 27 is provided on one side of the hinged sliding panel 22. A nail-attracting post 28 is provided on the inner side of the hinged base panel 21. The claw 27 and the nail-attracting post 28 are magnetically attracted. Through the cooperation of the hinged sliding panel 22 and the inward-retracting component 26, the evacuation area is significantly expanded, facilitating rapid evacuation of personnel. The swing sliding fan 22 maintains a straight line during displacement without shifting, achieving a balanced expansion of the evacuation channel. The symmetrical area on both sides ensures safer evacuation. Simultaneously, the engagement of the claw 27 and the suction pin 28 allows the swing sliding fan 22 to be fixed to the swing base fan 21 when it moves to the side, facilitating subsequent manual rotation. Furthermore, an outer protrusion 3 is fitted to the outer side of the swing sliding fan 22, which movably engages with an inner connecting block 4. The inner connecting block 4 is installed on the surface of the swing base fan 21. The engagement between the inner connecting block 4 and the outer protrusion 3 ensures the swing sliding fan 22 remains stable on the side, enabling the swing sliding fan 22 and the swing base fan 21 to rotate as a single unit, thus solving the problem of insufficient evacuation space.

[0024] The inner component 26 includes a side plate 261 installed on the side of the swing-opening sliding fan 22. A first positioning post 262 is fixed on the upper surface of the side plate 261. A hinged connecting rod 263 is rotatably sleeved on the outer surface of the first positioning post 262. A second positioning post 264 is rotatably engaged with the end face of the hinged connecting rod 263. A base block 265 is fixed on the lower surface of the second positioning post 264. Through the rotational engagement of the first positioning post 262, the hinged connecting rod 263 and the second positioning post 264, the sliding trajectory of the swing-opening sliding fan 22 is kept straight, realizing the function of stable sliding of the swing-opening sliding fan 22 and solving the problem of tilting during sliding, which affects the size of the evacuation space.

[0025] The hinged connecting rod 263 is slidably engaged with the straight rail 23 through the central pin. The side of the straight rail 23 is adapted to be installed with the swing base sash 21. Through the sliding engagement between the straight rail 23 and the hinged connecting rod 263, the straight shape of the swing sliding sash 22 is consistent with that of the straight rail 23, realizing the function of integrated sliding and integrated displacement, which significantly improves the efficiency of the double-opening evacuation passage and solves the defect of low door opening efficiency.

[0026] The surface of the door frame 1 is equipped with a sensor 6; for example, such as Figures 2-4 As shown.

[0027] The door frame 1 is a one-piece right-angled frame. By setting a sensor 6 on the door frame 1, wherein the sensor 6 is model GEKRONE / S-180, it has the function of detecting door opening by setting a sensing area on the outside of the door frame 1, which improves the efficiency of personnel evacuation and passage, and ensures the rapid evacuation of a large number of people in emergency situations.

[0028] The hinged base fan 21 is equipped with a flipping component 5, and there are two hinged sliding fans 22. The two hinged sliding fans 22 are symmetrically distributed. Through the symmetrically arranged hinged sliding fans 22, the evacuation area is multiplied, and the function of evacuation without congestion is achieved.

[0029] The flipping assembly 5 includes a sleeve 51 installed on the outer surface of the hinged base sash 21. A straight column 52 is rotatably fitted on the inner wall of the sleeve 51. The straight column 52 is adapted to the door frame 1 through a protrusion. Specifically, by rotating the straight column 52 and the sleeve 51, the hinged base sash 21 achieves the function of angle deflection, further expanding the evacuation area and making the evacuation door suitable for more public places.

[0030] A stabilizing base 53 is fixed to the front surface of the hinged base fan 21; for example, such as Figures 3-4 As shown.

[0031] The stabilizing base 53 is rotatably connected to a long rod 54 via its own shaft. The end face of the long rod 54 is provided with an inner slider 55. Through the cooperation of the inner slider 55 and the long rod 54, after the hinged sliding fan 22 is fixed inside the hinged base fan 21, the angle deflection is supported by the sliding of the inner slider 55. At the same time, the sliding distance of the inner slider 55 is reflected by the angle deflection, thus realizing the stable deflection function of the hinged base fan 21 and the hinged sliding fan 22.

[0032] The lower surface of the inner slider 55 is slidably fitted with an I-beam slide rail 56, which is arranged parallel to the straight rail 23. Specifically, through the sliding fit between the I-beam slide rail 56 and the inner slider 55, the sliding trajectory of the inner slider 55 can be kept linear, the angle deflection of the evacuation door is more uniform, and there will be no jamming during opening and closing.

[0033] Working principle: First, the sensor 6 senses the approach of a person. Then, the pulley 25 slides on the inner side of the curved path 24, causing the sliding fan 22 to move a short distance and then push out. As the sliding fan 22 continues to move laterally, the hinged connecting rod 263 rotates and engages with the first positioning post 262, the second positioning post 264, and the base block 265, allowing the sliding fan 22 to move closer to the sliding base fan 21. Then, the claw 27 on the side of the sliding fan 22 engages with the suction pin post 28, and the outer protrusion 3 engages with the inner connecting block 4, so that the sliding fan 22 is fixed to the inner wall of the sliding base fan 21.

[0034] Subsequently, the sleeve 51, which is set on the outer side of the hinged base fan 21, rotates on the outer surface of the straight column 52, causing the hinged base fan 21 to deflect at an angle. During the deflection process, the long rod 54 drives the inner slider 55 to slide along the inner side of the I-shaped slide rail 56, making the deflection of the hinged base fan 21 more stable, thereby providing more space for personnel evacuation.
