Detailed Description
The following description of the present invention will be made in detail with reference to the accompanying drawings 1 to 10.
Under the normal power-on condition, the external controller controls the automatic device to electrify the electromagnet 19, the electrified electromagnet 19 attracts the armature 18 to approach and compress the spring 20, and the worm wheel 8 fixedly connected with the armature 18 moves close to the left limiting disc 5 along the short shaft 4 under the limitation of the guide key 7, and when the attraction force of the electromagnet 19 is balanced with the elastic force of the spring 20, the worm wheel 8 is just matched with the automatic worm 21. Under the normal condition, when needs switch emergency exit 3, only need to start driving motor 22 corotation or reversal through external control ware for driving motor 22 drives automatic worm 21 and rotates, automatic worm 21 drives the lead screw 9 rather than an organic whole through turbine 8 again and rotates with optical axis 10 is synchronous, lead screw 9 rotates and will drive emergency exit 3 lateral sliding in casing 1, the walking wheel 33 cooperation guide rail 32 that emergency exit 3 lower extreme was equipped with can make emergency exit 3 lateral sliding respond well.
When power is off, the external controller is not electrified, the safety door 3 cannot be driven by an automatic device, the door can only be opened by a manual device at the moment, due to power failure, the electromagnet 19 is not electrified so as to lose attraction to the armature 18, under the self-recovery action of the spring 20, the turbine 8 slides rightwards along the short shaft 4 under the limitation of the guide key 7 and is in contact fit with the right limiting disc 6, the turbine 8 is just matched with the manual worm 11 at the moment, the rotating shaft 14 can be controlled to rotate forwards and backwards through the stepping motor 16 electrically connected with the standby power supply, or the rotating shaft 14 can be controlled to rotate forwards and backwards through the hand wheel 17 when the standby power supply is also unpowered, so that the safety door 3 can be opened and closed. The method specifically comprises the following steps: the rotating shaft 14 rotates to drive the second bevel gear 15 to rotate, the second bevel gear 15 drives the manual worm 11 to rotate through the first bevel gear 12, the manual worm 11 drives the screw rod 9 to rotate through the worm wheel 8, and therefore the safety door 3 is driven to transversely slide through the screw rod 9, and the safety door 3 can be opened and closed.
The worm of the worm wheel 8 has self-locking property, and the worm wheel 8 can only be driven by the automatic worm 21 or the manual worm 11 to finally realize the opening and closing of the safety door 3, so that the safety door 3 cannot be pulled violently to force the safety door 3 to open when the power is on or power is off, and the safety performance is high.
Further in order to carry out personal safety's protection, prevent emergency exit 3 when closing door opening 2, because various unexpected factors lead to emergency exit 3 frame to cause injury such as tong to the user, the event is equipped with and holds the braking protector tightly, when emergency exit 3 transversely slides right and seals door opening 2, when emergency exit 3 moves the driving gear 27 and the horizontal rack 28 meshing that reach between two backup pads 23 rightly, horizontal rack 28 will order about driving gear 27 anticlockwise rotation, driving gear 27 will drive rather than complex 32 clockwise rotation again, 32 drive rather than complex vertical rack 24 upwards slides along backup pad 23, and then make curved braking piece 25 and optical axis 10 cooperation restriction optical axis 10, leave the safety clearance between emergency exit 3 right side frame and the casing 1 right side wall this moment, avoid emergency exit 3 frame tong. In addition, the brake piece 25 is matched with the optical axis 10 to limit the optical axis 10, so that the optical axis 10 can be prevented from rotating due to an unexpected factor, and the lead screw 9 integrally connected with the optical axis 10 drives the safety door 3 to excessively slide rightwards and collide with the shell 1.
In order to ensure that the worm wheel 8 can be smoothly matched with the manual worm 11 after being separated from the automatic worm rod or the worm wheel 8 can be smoothly matched with the automatic worm 21 after being separated from the manual worm rod, and the tooth collision phenomenon between the worm wheel 8 and the manual worm 11 or the automatic worm 21 is avoided, an auxiliary rotating shaft 14 is arranged, the automatic worm 21 is coaxially and fixedly connected with a left gear 29, the manual worm 11 is coaxially and fixedly connected with a right gear 30, and the rear side wall of the shell 1 is longitudinally and rotatably connected with an intermediate gear 31 which is simultaneously meshed with the left gear 29 and the right gear 30, so that the arrangement of the manual worm 11 and the automatic worm 21 in the shell 1 can ensure that the worm wheel 8 can be smoothly matched with the manual worm 11 after being separated from the automatic worm rod, or the worm wheel 8 can be smoothly matched with the automatic worm 21 after being separated from the manual worm rod.
