It is specifically applicable to scenarios where the metal cover of the elevator firefighter control panel can be opened manually without special tools, ensuring that firefighters can quickly control the elevator in emergency situations such as fires. Background Technology

[0002] The firefighter control panel in an elevator is a control panel specifically designed for firefighters to safely use the elevator in emergencies such as fires. It is typically fixedly installed inside the elevator car wall and covered with a metal cover for protection. In existing technology, when an emergency occurs, the elevator's fire switch is activated, and the locking mechanism automatically unlocks, allowing the metal cover to be opened. However, if the locking mechanism fails and cannot unlock, the metal cover cannot be opened promptly, requiring firefighters to use specialized tools (such as pry bars or screwdrivers of specific sizes) to pry it open. However, in emergency scenarios like fires, if firefighters forget to bring the specialized tools or take too long to pry open the cover, they may be unable to quickly operate the control panel, potentially delaying rescue efforts and posing a safety hazard. Therefore, there is an urgent need for an opening device that allows the unlocking and opening of the firefighter control panel's metal cover manually without relying on specialized tools, to overcome the shortcomings of existing technology.

Detailed Implementation

[0009] The following combination Figure 1-4 The contents of this utility model will be described in detail through specific embodiments. Example

[0010] The elevator control panel opening device includes a metal cover plate 10 installed on the fire control panel car wall 11, and a locking mechanism installed on the back of the metal cover plate 10 and the fire control panel car wall 11. The locking mechanism is used to release / lock the connection between the metal cover plate 10 and the fire control panel car wall 11. The locking mechanism includes a frame-type electromagnet 8 and a spring seat locking assembly 6. The spring seat locking assembly 6 includes a card seat 601 fixed to the fire control panel car wall 11, a locking pin 602 fixedly installed on the card seat, and a spring 603 fixedly installed on the card seat. The frame-type electromagnet 8 is model KSD32-55 and manufactured by Beijing Enliji Machinery Equipment Co., Ltd. The frame-type electromagnet 8 will automatically retract when energized and automatically extend when de-energized.

[0011] When locked, the locking head of the frame electromagnet 8 interferes with the locking pin 602, and the metal cover 10 cannot be opened. When unlocked, the locking head of the frame electromagnet 8 retracts and moves out of the interference range with the locking pin 602, and the metal cover 10 can be opened. When unlocked, the tension of the spring 603 will push the metal cover 10 to open automatically.

[0012] A frame-type electromagnet 8 is provided on the back of the metal cover plate 10 and the fire control panel car wall 11, which cooperate with each other. The frame-type electromagnet 8 is used to lock or release the connection between the metal cover plate 10 and the fire control panel car wall 11. The elevator emergency power supply supplies power to the frame-type electromagnet 8. A flexible cylindrical pin 9 is provided on the lock head (electromagnet core) of the frame-type electromagnet 8. A switch fixing seat 5 is provided on the metal cover plate 10 for fixing the frame-type electromagnet 8. The switch fixing seat 5 is provided with a guide hole 501 for the flexible cylindrical pin 9 to slide left and right. A sliding assembly fixed to the metal cover plate 10 is provided between the switch fixing seat 5 and the metal cover plate 10.

[0013] How to use this utility model: Unlocking and Opening: In case of emergency such as fire, when firefighters need to operate the elevator control panel, no special tools are required. They can directly use their fingers to pry open the bolt 7 in the elongated hole 12 on the surface of the metal cover plate 10. The bolt 7 drives the slide plate 4 to slide along the guide groove of the small guide pad 3. The push pin 401 on the back of the slide plate 4 pushes the elastic cylindrical pin 9 to move along the guide hole 501 of the switch fixing seat 5. The lock head of the frame electromagnet 8 moves, which will release the lock between the metal cover plate 10 and the fire control panel car wall 11. After the lock is released, the spring 603 of the spring seat locking assembly 6 pushes the metal cover plate 10 to open automatically, and the firefighter can then operate the control panel.

[0014] Reset and close: After the operation is completed, the firefighter manually presses the metal cover 10 toward the fire control panel car wall 11 until the lock head of the frame electromagnet 8 locks with the latch 601 on the spring seat locking assembly 6; at this time, the slide plate 4, the shift post 401 and the bolt 7 are reset to their initial positions under the elastic force of the lock head spring, and the bolt 7 in the elongated hole 12 returns to its original position, and the device is ready for the next use.

[0015] This device requires no special tools; it can be unlocked by manually pulling the bolt 7. It has a stable structure and is suitable for emergency opening of elevator fire control panels. Only the elongated hole 12 and the bolt 7 are exposed on the surface of the metal cover plate 10. It is not much different from ordinary decorative parts in appearance, and ordinary passengers will find it difficult to identify it as an unlocking switch. In addition, there is a permanently etched text on the metal cover plate stating: "Operated by firefighters only," which greatly reduces the risk of unauthorized opening.
