Description
Technical Field
[0001] The utility model relates to a door opening device, in particular to an emergency door opening device. Background Art
[0002] The existing electric control door lock includes a card reader, which is used to receive the identification signal of a person entering a door and transmit this signal to a mechanism at the back end, so that the back-end mechanism can judge whether the identification signal of the person meets the qualification to open or close the door. When it is determined that the person meets the qualification, a door lock connected to the door will be braked. The door lock is used to receive an electric signal to activate the door lock to open or close the door. The door lock includes a door magnet and an electric lock. After the door magnet is powered on, it can generate magnetism to brake the electric lock to open or close the door.
[0003] Among them, when an emergency occurs, it may be impossible to open the door in real time due to many factors. For example, when a fire breaks out, everyone is busy escaping due to nervousness and does not carry an employee ID card with them. At this time, if it is still necessary to swipe the card reader through the employee ID card to open the door, it will lead to missing the opportunity to escape and danger will occur.
[0004] In the prior art, there is also an emergency escape device with a glass panel. By breaking the glass panel, the button behind the glass panel pops out to cut off the power supply circuit of the electric lock and open the door. However, this method may have the risk of the user being stabbed by glass fragments. After the glass is broken, the overall structure cannot be reused, and the original installation manufacturer must be found to reinstall it. Therefore, this structure does not meet the actual needs.
[0005] Therefore, the utility model proposes a brand-new emergency door opening device to solve the above-mentioned defects in the prior art. Summary of the Utility Model
[0006] Therefore, the purpose of the utility model is to solve the above-mentioned problems in the prior art. An emergency door opening device is proposed in the utility model. By using simple components, when the user presses the pressing part, the buckling part can be engaged with the triggering part, so that the trigger is located at the triggering position. At this time, the sensor will sense and send out the sensing signal and transmit the sensing signal to the relay switch, so that the relay switch cuts off the connection with the external power supply, and the door lock loses power, so the door can be automatically opened. This method can be used when an emergency occurs and the door cannot be opened. Just press the device of the utility model to cut off the power and open the door to facilitate the escape of personnel.
[0007] To achieve the above object, the present utility model proposes an emergency door opening device for use in the operation of a door lock of a door. The door lock includes: an electric lock that brakes the electric lock to energize or de-energize a door switch member connected to the electric lock, thereby opening or closing the door; the emergency door opening device includes: a trigger portion including a trigger post and a pressing portion located above the trigger post; the trigger portion is moved as a whole when pressed; a springback device is coupled to the trigger portion and is used to spring back the trigger portion to an initial position; in a non-emergency situation, the trigger portion is in an initial state, that is, the trigger portion is located at the initial position; wherein the trigger post is a trigger tube; a buckle portion is formed on the side of the trigger post, and the buckle portion is a groove located on one side of the trigger post; a abutting portion that abuts against one side of the trigger post when not operating; when an emergency occurs, the trigger portion is moved as a whole when pressed, and the abutting portion will engage with the buckle portion to fix the trigger portion at a trigger position; a sensor is located on a bottom surface, and when the trigger portion is triggered, the sensor will be sensed and an induction signal will be output; a relay switch is located between the door lock of the door and an external power supply; the external power supply is connected to the door lock by a power line to provide power to the door lock, and the relay switch is located on the power line and can turn on or off the power provided to the door lock; the relay switch is also connected to the sensor, wherein the sensor can control the opening or closing of the relay switch; wherein when the trigger portion is in the trigger position, the sensor will be sensed and an induction current will be output, and the sensor will transmit the induction current to the relay switch, so that the relay switch cuts off the connection with the external power supply, and the door lock loses power, so the door can be automatically opened. When there is a power failure and the door is disabled, the door switch member is automatically unlocked, so the door can be opened; by quickly pressing, the door lock can be quickly unlocked for easy escape.
[0008] Further, the springback device is a spring that surrounds the inside of the trigger post, and both ends of the spring are fixed so that it will be compressed and spring back due to the up and down movement of the trigger post.
[0009] Further, it further includes a main box body for accommodating the components of the emergency door opening device. The main box body includes an upper cover plate. The main box body has an upper opening that communicates with an opening and a reset hole of the upper cover plate; and the upper end of the pressing portion exposes from the upper opening of the main box body and the opening of the upper cover plate.
[0010] Further, the abutting portion is a columnar structure, one end of which forms an engaging portion to engage with the buckle portion, and the other end extends toward the reset hole of the upper cover plate to form a reset portion, allowing the user to press the reset portion to spring back the trigger portion to the initial position;
[0011] When the triggering part is triggered and the whole triggering part moves downward, the abutting part will face the groove, so it will penetrate into the groove on one side of the triggering column and abut against the edge of the groove, making the triggering column snap into the triggering position; when the abutting part disengages from the buckling part, the rebounding device will rebound the triggering part to the initial position.
[0012] Further, it further includes: a reset mechanism, which is used to contact the reset part below, so that the reset mechanism pushes the reset part back to its original position, and thus rebounds the triggering part to the initial position.
[0013] Further, the reset part is in an arc shape that tapers from bottom to top. Therefore, when the reset mechanism contacts the reset part, the reset mechanism pushes the reset part along the arc to make the abutting part return to its original position.

A sensing convex column extends from the lower edge of the pressing part, and the sensor is located above the bottom surface corresponding to the sensing convex column; when the triggering part is pressed down, the sensing convex column will touch a piezoelectric converter in the sensor, converting the touching pressure into the induced current.
[0015] Further, the abutting part is installed on a guiding mechanism, where the guiding mechanism is fixed on the bottom surface of the main box body, so that the abutting part can move relative to the main box body; and the guiding mechanism is a slide rail or a spring.
[0016] Further, it further includes a display board connected to a controller, and the display board displays the operation state of the triggering part; when the triggering part is triggered, a contact will be actuated, and a braking signal will be generated and transmitted to the controller to display the state of the controller on the display board.
[0017] Further, a contact convex column extends from the lower edge of the pressing part, and the contact is located above the bottom surface corresponding to the contact convex column; when the triggering part is pressed down, the contact convex column will touch the contact, thus making the contact close, and generating a braking signal and transmitting it to the controller.
[0018] Further, it further includes an integrated sensing mechanism, which includes:
[0019] A blocking sensor is connected to the controller, which can emit electromagnetic waves. When the electromagnetic waves are blocked by an external object, the blocking signal can be detected;
[0020] The controller is connected to the blocking sensor and the door lock. The controller is mainly connected to the door switch part of the door lock; the controller receives the input signal of the blocking sensor to judge whether there is a person who needs to enter or exit the door.
[0021] Furthermore, the integrated sensing mechanism further includes an entrance sensor connected to the controller and the door lock, for receiving the identification signal of the person attempting to enter the door and transmitting this signal to the backend mechanism, so that the backend mechanism can determine whether the identification signal of the person is qualified to open or close the door;
[0022] The controller also receives the signal from the entrance sensor to determine whether the person attempting to pass through is qualified, and generates an electrical signal to brake the door lock;
[0023] The entrance sensor is selected from a card reader, a biosensor, or a radio wave sensor.
[0024] Furthermore, the integrated sensing mechanism further includes: a PoE module connected to the network side through a PoE network cable or a PoE+ network cable, which can obtain electrical energy from a network switch, convert the electrical energy into a low-voltage current, and then send it to each required component to provide electrical energy

[0037] Now, with reference to the accompanying drawings, a preferred embodiment of the present utility model will be described in detail below in terms of its structural composition, as well as the functions and advantages that can be achieved.
[0038] Please refer to Figures 1 to 10 As shown, the emergency door opening device of the present utility model is used for the operation of a door lock 42 of a door 100. The door lock 42 includes: an electric lock 44. Braking the electric lock 44 can cause a door switch member 46 (such as a door magnetic) connected to the electric lock 44 to be energized or de-energized, thereby opening or closing the door 100.
[0039] As Figures 3 to 9 shown, the emergency door opening device of the present utility model includes the following components:
[0040] A main box body 10 includes an upper cover piece 12. The main box body 10 has an upper opening 14 which is communicated with an opening 13 and a reset hole 15 of the upper cover piece 12 (such as Figure 4 and Figure 5 ).
[0041] A triggering part 20 includes a triggering column 22 and a pressing part 24 located above the triggering column 22. The triggering part 20 can be moved as a whole by pressing (such as Figure 3 and Figure 6 ). A rebounding device 25 is coupled with the triggering part 20, and is used to rebound the triggering part 20 to an initial position. In non-emergency situations, the triggering part 20 is in an initial state, that is, the triggering part 20 is located at the initial position (such as Figure 6 ).
[0042] Among them, the triggering column 22 is a triggering tube 221 located inside the main box body 10. A buckle part 26 is formed on the side of the triggering column 22, and the buckle part 26 is a groove 261 located on one side of the triggering column 22 (such as Figure 6 ). The upper end of the pressing part 24 exposes out of the upper opening 14 of the main box body 10 and the opening 13 of the upper cover piece 12 (such as Figure 4 ).
[0043] Wherein, the resilient device 25 is a spring 251 which surrounds the inside of the trigger post 22, and both ends of the spring 251 are fixed so that it will be compressed and resilient due to the up and down movement of the trigger post 22. For example, the upper end of the spring 251 is fixed on the trigger portion 20 and its lower end is fixed on a bottom surface 17.
[0044] An abutting portion 30 which abuts against one side of the trigger post 22 (such as Figure 6 ) when it is not actuated. When an emergency occurs, the trigger portion 20 is pressed to cause overall movement, and the abutting portion 30 will engage with the buckle portion 26 to fix the trigger portion 20 at a trigger position (such as Figure 7 ).
[0045] Such as Figure 7 shown, wherein the abutting portion 30 is a columnar structure, one end of which forms an engaging portion 32 to engage the buckle portion 26, and the other end extends towards the reset hole 15 of the upper cover plate 12 to form a reset portion 34, allowing the user to press the reset portion 34 to make the trigger portion 20 resilient back to the initial position.
[0046] Wherein when the trigger portion 20 is triggered to cause the whole trigger portion 20 to move downward, the abutting portion 30 will face the groove 261 and thus penetrate into the groove 261 on one side of the trigger post 22 and abut against the edge of the groove 261, so that the trigger post 22 is buckled at the trigger position. When the abutting portion 30 disengages from the buckle portion 26, the resilient device 25 rebounds the trigger portion 20 to the initial position.
[0047] A reset mechanism 38 which is used to pass through the reset hole 15 of the upper cover plate 12 and contact the lower reset portion 34, so that the reset mechanism 38 pushes the reset portion 34 back to its original position, thus rebounding the trigger portion 20 to the initial position (such as Figure 8 and Figure 9 ).
[0048] In the present utility model, the reset portion 34 is an arc-shaped which tapers from bottom to top. Therefore, when the reset mechanism 38 contacts the reset portion 34, the reset mechanism 38 can push the reset portion 34 along the arc to make the abutting portion 30 return to its original position. The above form does not limit the protection scope of the present utility model. Mainly, any form that can achieve rebounding the trigger portion 20 to the initial position is within the protection scope of the present utility model.
[0049] In the present utility model, the abutting portion 30 can be installed on a guiding mechanism 31, wherein the guiding mechanism 31 is fixed on the bottom surface 17 of the main box body 10, so that the abutting portion 30 can move relative to the main box body 10. The guiding mechanism 31 is such as a slide rail or a spring.
[0050] A sensor 35 is located on the bottom surface 17. When the triggering portion 20 is triggered, the sensor 35 will be sensed and an induction signal will be output. For example, when the triggering portion 20 descends to the triggering position state, a piezoelectric converter 351 in the sensor 35 will be touched, and the pressure of the touch will be converted into an electric current.
[0051] As Figure 6 shown, in the present utility model, the pressing portion 24 is an enlarged plate body 241 and extends out of the periphery of the triggering post 22. A sensing convex post 251 extends from the lower edge of the pressing portion 24, and the sensor 35 is located on the bottom surface 17 corresponding to the sensing convex post 251. When the triggering portion 20 is pressed down, the sensing convex post 251 will touch the piezoelectric converter 351 in the sensor 35 (as Figure 7 ), and thus an electric current is generated.
[0052] A relay switch 36 is located between the door lock 42 of the door 100 and an external power supply 37 (as Figure 10 ). The external power supply 37 is connected to the door lock 42 by a power line 371 to provide power to the door lock 42, and the relay switch 36 is located on the power line 371, and it can turn on or off the power provided to the door lock 42. The relay switch 36 is also connected to the sensor 35, and the sensor 35 can control the opening or closing of the relay switch 36.
[0053] A battery 39 is connected to the sensor 35 to provide power.
[0054] When the triggering portion 20 is in the triggering position, the sensor 35 will be sensed and an induced current will be output. The sensor 35 transmits the induced current to the relay switch 36, so that the relay switch 36 cuts off the connection with the external power supply 37, and the door lock 42 loses power. Therefore, the door 100 can be automatically opened. The door lock 42 opens and closes the door 100, for example, by applying a traditional door switch member 46. When it loses power and becomes disabled, the door switch member 46 automatically unlocks, so the door 100 can be opened.
[0055] The above is the mechanism of the present utility model for quickly unlocking the door lock by quickly pressing in an emergency situation for the purpose of escape. The following describes the integrated door lock system 200 applicable to the present utility model.
[0056] The present utility model may further include a display board 52 connected to a controller 54, and the display board 52 can display the operation state of the triggering portion 20. When the triggering portion 20 is triggered, a contact 56 will be actuated, and a braking signal will be transmitted into the controller 54. Therefore, the controller 54 can know this state and display it on the display board 52.
[0057] For example, as Figure 2As shown, when the trigger part 20 is triggered, the contact point 56 is braked, so that the circuit connecting the contact point 56 and the controller 54 is turned on, and thus the controller 54 can know this state and display it on the display board 52.
[0058] Or as Figure 6 shown, a contact post 252 extends from the lower edge of the pressing part 24, and the contact point 56 is located on the upper surface of the bottom surface 17 corresponding to the contact post 252. When the trigger part 20 is pressed down, the contact post 252 will touch the contact point 56 (as Figure 7 ), so that the contact point 56 is closed, and a braking signal is generated and transmitted to the controller 54. Therefore, the controller 54 can know this state and display it on the display board 52.
[0059] Other structures that can generate signals to make the controller 54 know the actuation of the trigger part 20 are within the protection scope of the present utility model.
[0060] As Figure 1 shown, the integrated door lock system 200 of the present utility model further includes:
[0061] A blocking sensor 60 is connected to the controller 54, which can emit electromagnetic waves. When the electromagnetic waves are blocked by an external object, a blocking signal can be detected. For example, when applying reflected electromagnetic wave detection, the electromagnetic waves can be RF waves, infrared rays, laser light, etc.
[0062] The controller 54 is connected to the blocking sensor 60 and the door lock 42. In the present utility model, the controller 54 is mainly connected to the door switch part 46 of the door lock 42. The controller 54 can receive the input signal of the blocking sensor 60 to judge whether there is a person who needs to enter or exit the door.
[0063] The present utility model further includes an entrance sensor 62 connected to the controller 54 and the door lock 42, which is used to receive the identification signal of the person who wants to enter the door and transmit this signal to the backend mechanism. As Figure 1 shown, the backend mechanism judges whether the identification signal of the person meets the requirements to open or close the door. In the present utility model, the entrance sensor 62 can be implemented in a variety of ways. For example, a card reader is used to read the data of an external device and judge whether the holder of the device can enter the door; or a biological sensor, such as a sensor that senses biological fingerprint, face, eye, voice, palm vein, etc.; or a radio wave sensor, such as a Bluetooth sensor, NFC, etc.
[0064] The controller 54 also receives the signal from the entrance sensor 62 to judge whether the person who wants to pass meets the requirements, and generates an electrical signal to brake the door lock 42. In the present utility model, the door switch part 46 is braked.
[0065] A PoE module 40 (Power Over Ethernet PD module) is connected to the network end via a PoE network cable or a PoE+ network cable (not shown in the figure), can obtain electrical energy from the network switch, convert the electrical energy into a low-voltage current, such as a 12V current, and then send it to each required component to provide electrical energy. Preferably, the PoE+ network cable is used to obtain electrical energy. Figure 1 It shows that the PoE module 40 is connected to the display board 52, which is only for illustration purposes. Actually, the PoE module 40 is connected to each required component to provide electrical energy.
[0066] The advantage of the present utility model is that by using simple components, when the user presses the pressing part, the buckling part can be engaged with the triggering part, so that the trigger is located at the triggering position. At this time, the sensor will sense and emit the sensing signal and transmit the sensing signal to the relay switch, so that the relay switch cuts off the connection with the external power supply, and the door lock loses power, so the door can be automatically opened. This method can be used when an emergency occurs and it is impossible to open the door. Just press the device of the present utility model to cut off the power and open the door to facilitate the escape of personnel.
[0067] In summary, the user-friendly and considerate design of the present utility model quite meets the actual needs. It specifically improves the existing deficiencies, and has obvious breakthrough progress advantages compared with the prior art. It indeed has the improvement of efficacy and is not easy to achieve. The present utility model has not been publicly disclosed in domestic and foreign literatures and markets, and has met the provisions of the patent law.
[0068] The above detailed description is a specific description of a feasible embodiment of the present utility model, but this embodiment is not used to limit the protection scope of the present utility model. Any equivalent implementation or change made without departing from the technical spirit of the present utility model should be included in the protection scope of the present utility model.
