Detailed Description

Referring to fig. 1 and 2, an embodiment of the present invention provides an escape door, which can be installed at an exit of a safe passage of an office building or a residential building, can also be used as an entrance of a warehouse or a workshop, and can also 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 a normal condition, a lock cylinder (not shown in the figure) in the emergency escape push rod system locks the door body, so that external personnel can not enter a building or a warehouse through the escape door at will, when internal personnel need to pass through the escape door, the emergency escape push rod system can be operated to open the escape door, and the escape door can pass through the escape door to exit the building or the warehouse.

Referring to fig. 2 and 3, the emergency escape push rod system in the embodiment is arranged on the inner side of a door body (not shown in the figures), and includes a base 1, a push rod 2, a pushing device 3, a transverse moving member 4 and a lock cylinder rotating device 5, the base 1 is installed on the door body, the pushing device 3 includes a pressure lever 31 and a connecting rod 32, one end of the pressure lever 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 pressure lever 31, the other end is hinged with the base 1, one end of the transverse moving member 4 is hinged with the other end of the pressure lever 31, when one end of the push rod 2 is pushed towards the base 1, one end of the connecting rod 32 provides a fulcrum, and as can be known from the lever principle, a small acting force is applied to one end of the. Therefore, when the emergency escape pushing bar system is operated, one end of the pressing bar 31 is pushed and pressed by a small force, so that the other end of the pressing bar 31 can drive the transverse moving member 4 to move, and the effect of saving labor is achieved. In this embodiment, the other end of the cross member 4 is in rolling contact with the cylinder turning device 5, in other embodiments, the other end of the cross member 4 may be hinged or slidably connected with the cylinder turning device 5.

When an emergency occurs, most people can feel confused, the mind can not think calmly in a short time, and people can push the door body outwards by hands to open the escape door according to the escape instinct. Can bulldoze push rod 2 towards base 1 this moment, through the effect of connecting block 8, can be with power transmission to the one end of depression bar 31, make the one end of depression bar 31 bulldoze towards base 1, the other end of depression bar 31 rotates 4 relative cross moving member on the one hand, on the other hand drives 4 relative bases of cross moving member and slides, when 4 lateral shifting of cross moving member, can make 5 rotations of lock core rotating device, when 5 rotations of lock core rotating device, can drive the lock core and rotate, thereby open the emergency exit. When the goods in the warehouse need to be transported out of the warehouse, if the existing emergency escape push rod systems are used, the staff need to rotate the push rods forcibly to open the door and then transport the goods out. However in this embodiment, when the staff outwards transported the goods, will bulldoze the pushing ram 2 with the goods forward to open the door fast, the staff can directly transport the goods out of the warehouse, has improved work efficiency.

Referring to fig. 2, 7 and 8, the pushing device 3 is provided with a restoring member 6 for restoring the pushing device 3, and of course, the restoring member 6 may be provided on the traverse member 4 or the key cylinder turning device 5. Referring to fig. 2, in the present embodiment, the pushing devices 3 are provided in two sets, two ends of the pushing rod 2 are respectively connected to two pressing rods 31 of the two sets of pushing devices 3 through connecting blocks 8, and the transverse moving member 4 is hinged to the pressing rods 31 of one set of pushing devices 3. Referring to fig. 7 and 8, the reset member 6 is a torsion spring, one end of the link 32, the pressure lever 31 and the torsion spring are concentrically hinged, one leg of the torsion spring abuts against the pressure lever 31, and the other leg abuts against the link 32. When the push lever 2 is released, the urging means 3 is reset by the torsion spring, so that the push lever 2 and the lateral moving member 4 are reset.

Referring to fig. 3 and 4, the key cylinder rotating device 5 includes a rotating disc 51, a key cylinder hole 52 is formed on the rotating disc 51, the key cylinder hole 52 is used for installing a key cylinder (not shown in the figures), a shift lever 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 shift lever 53, the first roller 531 is in rolling connection 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 rotate the rotating disc 51. In other embodiments, a sliding slot may be disposed on the lateral moving member 4, and a pin body is disposed on the shift lever 53, 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 shift lever 53 to rotate. Of course, it is also possible to rotate the shift lever 53 by hinging a connecting rod between the cross-moving member 4 and the shift lever 53, when the cross-moving member 4 moves transversely. In this embodiment, driving lever 53 roll connection lateral shifting member 4 can make the frictional force between driving lever 53 and the lateral shifting member 4 reduce, realizes laborsaving effect, and when depression bar 31 reset and drives lateral shifting member 4 and reset, under the effect of gravity, first gyro wheel 531 will be followed inclined plane 41 and rolled down and sent to make rolling disc 51 rotate, rotate the lock core back original position, lock the door.

Referring to fig. 1, 2, 5 and 6, in order to protect 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, the two ends of the push rod 2 are both slidably connected with arc covers 7, one end of each arc cover 7 far away from the push rod 2 is rotatably connected to the base 1 through a rotating shaft 71, and when the push rod 2 pushes one end of the pressing rod 31 towards the base 1, the push rod 2 drives one end of each arc cover 7 to rotate relative to the base 1. Arc lid 7, push rod 2 and base 1 form the visor of the inside spare part of protection emergency escape push rod system, simultaneously, when bulldozing push rod 2 towards base 1, because arc lid 7 sliding connection push rod 2 and arc lid 7 keep away from the one end of push rod 2 and can rotate relative to base 1, arc lid 7 will not restrict the motion of push rod 2. In order to prevent the arc-shaped cover 7 from sliding relative to the pushing rod 2, the arc-shaped cover 7 and the pushing rod 2 are quickly worn due to the action of friction, the second roller 33 is arranged at one end of the pressing rod 31, the outer side surface of the arc-shaped cover 7 is a curved surface, the pushing rod 2 abuts 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.
