Detailed Description
Referring to fig. 1 and 2, the embodiment of the invention provides an escape door, which can be installed at the exit of a safe passage of a office building or a residential building, can also be used as an exit door of a warehouse or a workshop, and can be installed at other places. The escape door comprises a door body (not shown in the figure) and an emergency escape push rod system arranged on the door body, wherein under normal conditions, a lock cylinder (not shown in the figure) in the emergency escape push rod system locks the door body, so that an external person cannot enter a building or a warehouse through the escape door at will, and when the internal person needs to pass through the escape door, the emergency escape push rod system can be operated to open the escape door, so that the escape door can be discharged out of the building or the warehouse through the escape door.
Referring to fig. 2 and 3, the emergency escape push rod system in this embodiment is disposed inside a door body (not shown in the drawings), and includes a base 1, a push rod 2, a pushing device 3, a lateral moving member 4 and a lock cylinder rotating device 5, where the base 1 is mounted on the door body, the pushing device 3 includes a push rod 31 and a connecting rod 32, one end of the push rod 31 is hinged with a connecting block 8 for connecting the push rod 2, the other end is slidably connected with the base 1, one end of the connecting rod 32 is hinged with the push rod 31, the other end is hinged with the base 1, one end of the lateral moving member 4 is hinged with the other end of the push rod 31, when pushing one end of the push rod 2 towards the base 1, one end of the connecting rod 32 provides a supporting point function, and as known from the lever principle, a small acting force is applied to one end of the push rod 2, and a large acting force can be generated at the other end of the push rod 2. Therefore, when the emergency escape pushing rod system is operated, one end of the pressing rod 31 is pushed by small force, and the other end of the pressing rod 31 drives the transverse moving part 4 to move, so that the labor-saving effect is achieved. In this embodiment, the other end of the lateral movement 4 is connected to the key cylinder turning device 5 in a rolling manner, and in other embodiments, the other end of the lateral movement 4 may be hinged or slidingly connected to the key cylinder turning device 5.
When an emergency occurs, most people can be in a hurry, the mind cannot be calm and think in a short time, and people can push the door body outwards by hands to hope to open the escape door according to the escape principle. At this time, the pushing rod 2 is pushed towards the base 1, and the force can be transmitted to one end of the pressing rod 31 through the action of the connecting block 8, so that one end of the pressing rod 31 is pushed towards the base 1, the other end of the pressing rod 31 rotates relative to the transverse moving member 4 on one hand, the transverse moving member 4 is driven to slide relative to the base 1 on the other hand, when the transverse moving member 4 transversely moves, the lock cylinder rotating device 5 can be rotated, and when the lock cylinder rotating device 5 rotates, the lock cylinder can be driven to rotate, so that the escape door is opened. When the goods in the warehouse are required to be transported out of the warehouse, if the existing emergency escape pushing bar systems are used, workers are required to forcefully rotate the pushing bar, and after the door is opened, the goods are transported out. But in this embodiment, when the staff carries the goods outwards, will bulldoze pushing rod 2 with the goods forward to open the door fast, the staff can directly carry the goods out of warehouse, has improved work efficiency.
Referring to fig. 2, 7 and 8, the pressing device 3 is provided with a reset member 6 for resetting the pressing device 3, but the reset member 6 may be provided on the traverse member 4 or the key cylinder turning device 5.

When the push bar 2 is released, the pushing device 3 is reset under the action of the torsion spring, so that the push bar 2 and the transverse moving member 4 are reset.
Referring to fig. 3 and 4, the lock cylinder rotating device 5 includes a rotating disc 51, a lock cylinder hole 52 is formed in the rotating disc 51, the lock cylinder hole 52 is used for installing a lock cylinder (not shown in the drawings), a deflector rod 53 is fixedly installed on the rotating disc 51, referring to fig. 4, the transverse moving member 4 has an inclined surface 41, a first roller 531 is arranged on the deflector rod 53, the first roller 531 rolls and is connected with the inclined surface 41, and when the transverse moving member 4 transversely moves, the first roller 531 rolls upwards along the inclined surface 41 to enable the rotating disc 51 to rotate. In other embodiments, a sliding slot may be provided on the lateral moving member 4, and a pin body is provided on the lever 53, where the pin body is slidably connected to the sliding slot, and when the lateral moving member 4 moves laterally, the pin body slides in the sliding slot, so as to drive the lever 53 to rotate. Of course, it is also possible to hinge a connecting rod between the traverse member 4 and the shift lever 53, and when the traverse member 4 is moved laterally, the shift lever 53 is rotated by the connecting rod. In this embodiment, the shift lever 53 is connected with the lateral moving member 4 in a rolling manner, so that the friction between the shift lever 53 and the lateral moving member 4 is reduced, and a labor-saving effect is achieved, when the compression lever 31 resets to drive the lateral moving member 4 to reset, under the action of gravity, the first roller 531 rolls downwards along the inclined plane 41, so that the rotating disc 51 rotates, the lock cylinder rotates back to the original position, and the door is locked.
Referring to fig. 1,2, 5 and 6, in order to protect the internal components of the emergency escape push rod system, a protective cover needs to be added outside the emergency escape push rod system, in this embodiment, two ends of the push rod 2 are slidably connected with arc covers 7, one end of the arc cover 7 away from the push rod 2 is rotatably connected with the base 1 through a rotation shaft 71, and when the push rod 2 pushes one end of the compression rod 31 towards the base 1, the push rod 2 drives one end of the arc cover 7 to rotate relative to the base 1. The arc-shaped cover 7, the pushing rod 2 and the base 1 form a protective cover for protecting parts inside the emergency escape pushing rod system, and meanwhile, when the pushing rod 2 is pushed towards the base 1, the arc-shaped cover 7 is in sliding connection with the pushing rod 2, and one end, far away from the pushing rod 2, of the arc-shaped cover 7 can rotate relative to the base 1, so that the arc-shaped cover 7 can not limit the movement of the pushing rod 2. In order to prevent the arc-shaped cover 7 from sliding relative to the pushing bar 2, the arc-shaped cover 7 and the pushing bar 2 are rapidly worn due to the action of friction force, one end of the pressing rod 31 is provided with a second roller 33, the outer side surface of the arc-shaped cover 7 is a curved surface, the pushing bar 2 is propped against the outer side of the curved surface, and the second roller 33 is in rolling connection with the inner side of the curved surface.
