Detailed Description
In order that those skilled in the art will better understand the technical solution of the present invention, the following detailed description is given with reference to the accompanying drawings:
referring to fig. 1, 2, 3, 4, 5 and 6, in accordance with a preferred embodiment of the present invention, a locking device of an escape push rod lock includes a motor 1, a thrust bearing 2, a cam 3, a controller 5, a timer 6, an alarm 7 and a reset switch 8.
The motor 1 is arranged on the shell 103 of the escape push rod lock 100 through the motor bracket 4; the output end of the motor 1 is connected with the cam 3 through a thrust bearing 2; specifically, the motor support 4 comprises a horizontal plate 41 and a vertical plate 42 to form an L shape, the horizontal plate 41 of the motor support 4 is fixed on the shell of the escape push rod lock 100 through a bolt, a motor mounting hole is formed in the vertical plate 42 of the motor support 4, the motor 1 and the cam 3 are respectively arranged on two sides of the vertical plate 42 of the motor support 4, the motor 1 is fixed on the vertical plate 42 of the motor support 4 through a bolt, the output end of the motor 1 is connected with the cam 3 after passing through the motor mounting hole, and the thrust bearing 2 is arranged at the joint of the output end of the motor 1 and the cam 3.
The lower part of the cam 3 is provided with a push rod tail blocking notch 31, when the escape push rod lock 100 is in the locking state, the push rod tail 101 of the escape push rod lock 100 is positioned in the push rod tail blocking notch 31, so that the push rod tail 101 is abutted against the cam 3 to maintain the locking state of the escape push rod lock 100.
The motor 1, the timer 6, the alarm 7 and the reset switch 8 are respectively and electrically connected with the controller 5. The timer 6, the alarm 7, the reset switch 8 and the controller 5 are arranged at the periphery of the escape push rod lock 100.
According to the locking device of the escape push rod lock, when the escape push rod lock is in a locked state, the tail strip 101 of the push rod is abutted against the cam 3, the locked state of the escape push rod lock 100 is maintained, when the push rod 102 is pressed down, the escape push rod lock 100 cannot be directly opened due to the abutting effect of the cam 3, the alarm 7 is triggered to give an alarm when the push rod is pressed down, the controller 5 receives an alarm signal and controls the timer 6 to start timing, countdown time can be preset on the timer 6, for example, 5-15 s countdown time can be preset, after the countdown is finished, the controller 5 controls the motor 1 to rotate, the motor 1 drives the cam 3 to rotate, the cam 3 is separated from the tail strip 101 of the push rod, and therefore the push rod can be pressed down continuously to open the escape push rod lock. When the fire escape door is closed again, the reset switch 8 is pressed, the reset switch 8 transmits a signal to the motor 1, the motor 1 rotates to drive the cam 3 to rotate, the push rod tail strip 101 is abutted to the cam 3, and the alarm 7 stops giving an alarm.
The locking device of the escape push rod lock realizes the locking function through the collision of the cam 3 and the tail strip 101 of the push rod, the alarm 7 can be triggered to give an alarm when the push rod is pressed down, an operator is reminded of paying attention to the fact that the push rod can be stopped to be pressed down in time if the operation is wrong, and the collision of the cam 3 and the tail strip 101 of the push rod can be recovered after the reset switch 8 is pressed down.
In conclusion, the locking device of the escape push rod lock is connected with the tail strip of the push rod of the escape push rod lock, has the functions of alarming and resetting, can ensure the normal use of the escape push rod lock, and does not need to be provided with an electromagnetic lock.
It should be understood by those skilled in the art that the above embodiments are only for illustrating the present invention and are not to be used as a limitation of the present invention, and that changes and modifications to the above described embodiments are within the scope of the claims of the present invention as long as they are within the spirit and scope of the present invention.
