Technical Field
[0001] The utility model relates to the technical field of escape doors, in particular to an escape door suitable for use by a group of people. Background Art
[0002] Safety passage door is also called emergency evacuation door, safety emergency door, escape door, safety exit door, emergency exit door, emergency passage door, fire passage door. Generally, this door is a must-have for building fire safety and is used as a fast passage for emergency escape and fire rescue.
[0003] The escape door is usually in a normally closed state at ordinary times. When an emergency occurs, people can open the escape door to escape by unscrewing the lock with a handle. In order to take into account the usage habits of the mainstream population, the handle of the escape door is usually set at a certain distance from the ground. This results in children not being able to turn the door handle at the best grip angle and force method when using it, and thus being unable to quickly open the escape door, which may affect the speed of escape and cause a tragedy. In addition, when the lock is accidentally damaged and the lock tongue cannot be retracted, the escape door cannot be opened by the handle, resulting in obstruction of the escape route, which seriously affects the escape speed. Therefore, in view of the above problems, an escape door suitable for use by multiple people is proposed. Utility Model Content
[0004] The technical problem to be solved by the utility model is to provide an escape door suitable for use by multiple people. The escape door can simply and quickly disable the emergency disabling socket through a disabling operating piece arranged at a lower position, thereby losing the restraining effect on the lock tongue, and then the door can be opened by only pushing the mother door, thereby simplifying the door opening operation and meeting the needs of multiple people for fast and efficient escape. Moreover, when the lock is damaged and the lock tongue cannot be retracted, the emergency disabling socket has lost its restraining effect on the lock tongue, so the escape door can be smoothly opened for escape. This solves the technical problems in the prior art that the position of the door handle is not convenient for children or people with limited mobility to quickly open the escape door for escape, and the escape door cannot be smoothly opened when the lock is damaged and the lock tongue cannot be retracted.
[0005] The technical solution adopted by the embodiment of the present application to solve the technical problem is:
[0006] An emergency escape door suitable for multiple people to use, including a door frame. A sub-door and a mother door are respectively rotatably connected to the two side frames of the door frame through hinges. A lock is installed on the mother door. An installation groove is opened on the sub-door. An operation groove is opened at the lower part of the front end face of the sub-door. An emergency fail-safe socket is embedded in the installation groove, and the lock tongue of the lock is inserted into the emergency fail-safe socket. A fail-safe operating member is arranged in the operation groove. Among them, the emergency fail-safe socket includes a C-shaped member. A lock tongue clamping plate is rotatably connected to the opening of the C-shaped member. A clamping piece is fixedly arranged on the C-shaped member. A limit bolt is inserted into the clamping piece. The fail-safe operating member is arranged at the bottom of the limit bolt. When the limit bolt is inserted into the clamping piece, the inner end face of the limit bolt is in close contact with the lock tongue clamping plate.
[0007] Among them, the fail-safe operating member includes a guide rod vertically arranged in the operation groove. A dial is slidably arranged on the guide rod. The rear end of the dial is fixedly connected to the bottom of the limit bolt, so that the dial can always slide up and down along the guide rod during movement, and then drive the limit bolt straight up and down to ensure the smoothness of the limit bolt during movement.
[0008] Through the above structural form, the fail-safe operating member is used to control the limit bolt to slide out of the clamping piece. At this time, the lock tongue clamping plate loses the support of the limit bolt and can rotate freely. When the mother door is directly pushed, the lock tongue will apply a thrust to the lock tongue clamping plate to make it rotate. At this time, the lock tongue clamping plate completely loses the restraint on the lock tongue, so that it is impossible to turn the door handle and only need to push the mother door to open it for escape. And because the operation groove is set at a relatively low position, it is convenient for children to operate. At the same time, when the lock is accidentally damaged and the lock tongue cannot retract, the mother door can also be directly pushed open for escape through the above method.
[0009] In a possible implementation manner, an iron sliding cylinder is slidably sleeved on the guide rod. The bottom of the sliding cylinder is fixedly connected to the upper end face of the dial. A permanent magnet sheet sleeved outside the guide rod is fixedly arranged at the top of the operation groove. The permanent magnet sheet can adsorb the sliding cylinder.
[0010] Through the above structural form, since the permanent magnet sheet can adsorb and fix the sliding cylinder, it can avoid the limit bolt from sliding down under the action of gravity, resulting in the emergency fail-safe socket failing when it is not necessary and affecting normal use.
[0011] In a possible implementation manner, an anti-failure plug block made of elastic material is filled between the lower part of the dial and the bottom of the operation groove. A pulling opening is opened on the front end face of the anti-failure plug block.
[0012] Through the above structural form, the anti-failure plug block can support the dial, avoid the limit bolt from sliding down under the action of gravity, resulting in the emergency fail-safe socket failing when it is not necessary and affecting normal use, and constitutes a second guarantee.
[0013] In a possible implementation, a hinge seat is provided at one end of the C-shaped member away from the mother door, a rotating shaft is rotatably provided in the hinge seat, and both ends of the rotating shaft are fixedly connected to the lock tongue clamp.
[0014] The above-mentioned structural form provides the necessary structural basis for the rotational connection between the lock tongue clamp and the C-shaped member.
[0015] In a possible implementation, a torsion spring connecting piece is fixedly provided at one end of the lock tongue clamp close to the rotating shaft, and the torsion spring connecting piece is movably sleeved outside the rotating shaft. A prestressed torsion spring sleeved outside the rotating shaft is provided between the torsion spring connecting piece and the hinge seat, and the upper and lower ends of the prestressed torsion spring are respectively fixedly connected to the hinge seat and the torsion spring connecting piece.
[0016] Through the above-mentioned structural form, the prestressed torsion spring can apply a torque to the lock tongue clamp to rotate outward, thereby preventing the lock tongue clamp from rotating inward and affecting the normal insertion of the lock tongue. At the same time, when the restraining force of the limit bolt is removed, the prestressed torsion spring can push the lock tongue clamp to rotate outward with a preset torque, so that the emergency disabling socket instantly loses its restraining effect.
[0017] In a possible implementation, a bolt sliding groove for sliding the limit bolt is provided in the sub-door, and the upper and lower ends of the bolt sliding groove are respectively connected to the installation groove and the operation groove.
[0018] The above-mentioned structural form provides a necessary structural basis for the sliding of the limit bolt.
[0019] In a possible implementation, the sub-door is fixedly connected to the door frame via a latch, and a door closer is connected between the main door and the door frame.
[0020] Through the above-mentioned structural form, the functional requirements of the sub-door and the main door during normal use can be met.
[0021] In summary, the utility model includes the following beneficial technical effects:
[0022] The limit bolt is manipulated by the paddle to slide out of the card plate. At this time, the lock tongue clamp loses the support of the limit bolt and will rotate outward under the action of the prestressed torsion spring. At this time, the lock tongue clamp completely loses its restraining effect on the lock tongue, making it impossible to turn the door handle. It can be opened for escape by only pushing the mother door. Since the operating slot is set at a low position, it is convenient for children and other disabled people to operate. At the same time, when the lock is accidentally damaged and the lock tongue cannot be retracted, the mother door can also be directly pushed open for escape in the above manner.

Specific embodiments
[0030] The technical solutions in the embodiments of the present application are to solve the problems in the above-mentioned background technology, and the general idea is as follows:
[0031] As Figure 1 - Figure 3 shown, an escape door applicable to multiple groups of people provided in this embodiment includes a door frame 1, on both sides of which a sub-door 21 and a mother door 22 are respectively rotatably connected through hinges. A lock is installed on the mother door 22. An installation groove 211 is opened on the sub-door 21. An operation groove 212 is opened at the lower part of the front end face of the sub-door 21. An emergency fail-safe socket 3 is embedded in the installation groove 211, and the lock tongue of the lock is inserted into the emergency fail-safe socket 3. A fail-safe operating member 4 is arranged in the operation groove 212.
[0032] Among them, the emergency fail-safe socket 3 includes a C-shaped member 31. A locking tongue plate 32 is rotatably connected at the opening of the C-shaped member 31. A clamping piece 33 is fixedly arranged on the C-shaped member 31. A limit bolt 34 is inserted into the clamping piece 33. The fail-safe operating member 4 is arranged at the bottom of the limit bolt 34. And when the limit bolt 34 is inserted into the clamping piece 33, the inner end face of the limit bolt 34 is in close contact with the locking tongue plate 32. This structural form can ensure that the locking tongue plate 32 is always supported by the limit bolt 34 in the working state, thereby restricting the locking tongue and playing the role of a normal socket.
[0033] In addition, the sub-door 21 is fixedly connected to the door frame 1 through a bolt, and a door closer is connected between the main door 22 and the door frame 1.
[0034] Through the above structural form, the fail-safe operating member 4 is used to control the limit bolt 34 to slide out of the clamping piece 33. At this time, the locking tongue plate 32 loses the support of the limit bolt 34 and can rotate freely. When the main door 22 is directly pushed, the locking tongue will apply a thrust to the locking tongue plate 32 to make it rotate. At this time, the locking tongue plate 32 completely loses the restraint on the locking tongue, so that the door handle cannot be rotated and only by pushing the main door 22 can it be opened for escape. And because the operation slot 212 is set at a relatively low position, it is convenient for children to operate; at the same time, when the lock is accidentally damaged and the locking tongue cannot retract, the main door 22 can also be directly pushed open through the above method for escape.
[0035] As Figure 4 shown, the fail-safe operating member 4 includes a guide rod 42 vertically arranged in the operation slot 212. A slider 41 is slidably arranged on the guide rod 42. The rear end of the slider 41 is fixedly connected to the bottom of the limit bolt 34. Through the above structural form, it can be ensured that the slider 41 can always slide up and down along the guide rod 42 during movement, thereby driving the limit bolt 34 straight up and down to ensure the smoothness of the limit bolt 34 during movement.
[0036] As Figure 4 shown, an iron sliding cylinder 44 is slidably sleeved on the guide rod 42. The bottom of the sliding cylinder 44 is fixedly connected to the upper end face of the slider 41. A permanent magnet sheet 43 sleeved outside the guide rod 42 is fixedly arranged at the top of the operation slot 212. The permanent magnet sheet 43 can adsorb the sliding cylinder 44. In addition, an anti-failure plug block 45 made of elastic material is filled between the lower part of the slider 41 and the bottom of the operation slot 212. A pulling opening 451 is opened on the front end face of the anti-failure plug block 45.
[0037] In the above structural form, since the permanent magnet sheet 43 can adsorb and fix the sliding cylinder 44, it can prevent the limit bolt 34 from sliding down under the action of gravity, resulting in the failure of the emergency fail-safe socket 3 when it is not necessary and affecting normal use. The anti-failure plug 45 can support the dial 41 and prevent the limit bolt 34 from sliding down under the action of gravity, resulting in the failure of the emergency fail-safe socket 3 when it is not necessary and affecting normal use. These two structural forms constitute a double guarantee.
[0038] As Figure 4 shown, at one end of the C-shaped member 31 away from the mother door 22, a hinge seat 311 is provided. A rotating shaft 321 is rotatably arranged in the hinge seat 311. Both ends of the rotating shaft 321 are fixedly connected to the lock tongue clamping plate 32. A torsion spring connecting piece 322 is fixedly arranged at one end of the lock tongue clamping plate 32 close to the rotating shaft 321. The torsion spring connecting piece 322 is movably sleeved outside the rotating shaft 321. A prestressed torsion spring 35 sleeved outside the rotating shaft 321 is arranged between the torsion spring connecting piece 322 and the hinge seat 311. The upper and lower ends of the prestressed torsion spring 35 are respectively fixedly connected to the hinge seat 311 and the torsion spring connecting piece 322.
[0039] Through the above structural form, the prestressed torsion spring 35 can apply a torque to the lock tongue clamping plate 32 to rotate outward, thereby preventing the lock tongue clamping plate 32 from rotating inward and affecting the normal insertion of the lock tongue. At the same time, when the constraint force of the limit bolt 34 is removed, the prestressed torsion spring 35 can push the lock tongue clamping plate 32 to rotate outward with a preset torque, so that the emergency fail-safe socket 3 instantly loses its constraint effect.
[0040] As Figure 2 、 Figure 4 shown, a bolt sliding groove 213 for the limit bolt 34 to slide is provided in the sub-door 21, and the upper and lower ends of the bolt sliding groove 213 are respectively communicated with the installation groove 211 and the operation groove 212. Through the above structural form, a necessary structural basis is provided for the sliding of the limit bolt 34.
[0041] The working principle and working process of the present utility model:
[0042] When an emergency occurs and it is not convenient to use the door handle to open the mother door 22 for escape, the limit bolt 34 is controlled to slide out of the clamping piece 33 through the dial 41. At this time, the lock tongue clamping plate 32 loses the support of the limit bolt 34 and will rotate outward under the action of the prestressed torsion spring 35. At this time, the lock tongue clamping plate 32 completely loses the constraint on the lock tongue, so that the door handle cannot be rotated and only the mother door 22 needs to be pushed to open it for escape. And because the operation groove 212 is set at a relatively low position, it is convenient for children and other inconvenient people to operate.
[0043] Meanwhile, in case of an emergency, it is also a problem that may easily occur that the lock tongue cannot retract due to accidental damage to the lock, and at this time, the escape door cannot be opened through the handle, resulting in the blockage of the escape passage. However, the mother door 22 can be directly pushed open for escape through the above method.
[0044] Finally, it should be noted that: Obviously, the above embodiments are only examples given to clearly illustrate the present invention, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
