Description
Technical Field
[0001] This utility model relates to the field of cabinet technology, and in particular to an intelligent IT cabinet with emergency unlocking capability and an emergency cabinet lock component. Background Technology
[0002] Intelligent IT cabinets consist of a sealed cabinet body, a monitoring system, a power distribution system, and a cooling system. Due to their high integration, they can be directly deployed to servers and are widely used in various small data centers. As the intelligent IT cabinet itself is a sealed structure, it needs to be opened first to assist in heat dissipation and protect the load when the IT load triggers a high-temperature alarm. Data centers are often unattended, making it difficult to manually open the cabinet door immediately; therefore, an automatic door opening function is required. Existing technologies include adding a gas strut to the cabinet door to assist opening, and using a magnetic lock to lock the door. At high temperatures, the magnetic lock is de-energized, and the cabinet door opens automatically. This solution requires overcoming the tension of the gas strut when closing the door, making it laborious, and the magnetic lock is constantly in an engaged state, consuming power, which is not energy-efficient. Another solution uses an electromagnetic spring-loaded unlocking mechanism to achieve automatic door opening. In this solution, the latch is normally locked; when the internal temperature is high, the electromagnetic cylinder is driven by an electrical signal, automatically pressing down the latch hook, causing the latch to disengage, and simultaneously the elastic push rod extends to open the cabinet door. This solution offers no resistance when closing the door, consumes no power under normal conditions, is convenient to use, and is energy-efficient. The drawback of this solution is that in the event of an emergency power outage, the electromagnetic cylinder will not have any driving force, the mechanical lock will not be able to disengage, and the cabinet door will not be able to be opened. Summary of the Invention
[0003] Based on the above problems, the purpose of this utility model is to provide an intelligent IT cabinet and emergency cabinet lock components that can be unlocked in an emergency. In addition to the conventional password unlocking, it can also automatically unlock in high temperature conditions and manually unlock in case of emergency power failure.
[0004] The technical solution adopted in this utility model is an intelligent IT cabinet capable of emergency unlocking, comprising a cabinet, an intelligent terminal, a data collector, a temperature sensor, a lock control board, and an emergency cabinet lock assembly, wherein:
[0005] The intelligent terminal is installed on the cabinet door and has a touch screen display. The data collector, temperature sensor and lock control board are installed inside the cabinet.
[0006] The emergency cabinet lock assembly includes an electromagnetic spring-loaded lock, a lock body mounting plate, a pivot, a lever, and a push-out lock. The lock body mounting plate is fixedly mounted on the cabinet frame. The spring-loaded lock body and pivot of the electromagnetic spring-loaded lock are both fixedly mounted on the lock body mounting plate. The push-out lock is fixedly mounted on the cabinet door. The lever is rotatably mounted on the pivot. When the door is closed, the outer end of the lever is located above the vertical latch of the push-out lock, and the inner end of the lever is located above the electromagnetic cylinder of the electromagnetic spring-loaded lock. The electromagnetic cylinder is installed on the inner side of the upper part of the spring-loaded lock body. A latch that cooperates with the spring-loaded lock body is fixedly mounted on the cabinet door. The spring-loaded lock body also has an elastic push rod perpendicular to the cabinet door.
[0007] The electromagnetic cylinder is electrically connected to the locking control board, the temperature sensor is electrically connected to the data acquisition unit, and both the locking control board and the data acquisition unit are electrically connected to the smart terminal.
[0008] The smart terminal collects the temperature inside the cabinet through a data collector and a temperature sensor, and also has a conventional password door opening function.
[0009] The smart terminal, linked to the lock control board, controls the electromagnetic spring-loaded lock to open. Under normal circumstances, entering the opening password on the smart terminal will automatically open the cabinet door, allowing maintenance personnel to perform server installation, repair, and maintenance. If the smart IT cabinet suddenly experiences high temperatures, the data collector receives high-temperature data from the temperature sensor and reports it to the smart terminal. The smart terminal then sends a command to the lock control board to open the cabinet door. When the smart terminal is connected to the control center, it can also upload alarm information to the control center and notify users via phone or SMS.
[0010] In the event of a power outage, the emergency key can be inserted into the ejector lock from the front of the cabinet door. Rotating the lock cylinder will cause the vertical bolt of the ejector lock to rise, thereby raising the outer end of the lever. The lever rotates around the pivot, and the inner end of the lever descends, pressing down the electromagnetic cylinder that unlocks the electromagnetic spring. This causes the latch hook to open, the latch to disengage, and the cabinet door to open under the force of the elastic push rod.
[0011] Furthermore, the specific structure of the ejector lock fixedly installed on the cabinet door is as follows: the lock housing is fixedly installed on the cabinet door, and the lock body of the ejector lock is fixedly installed inside the lock housing;
[0012] A lock housing cover plate is fixedly installed on the lock housing. A through hole is provided on the lock housing cover plate. When the door is closed, the outer end of the lever passes through the through hole and extends into the lock housing and is located above the vertical bolt of the push-out lock.
[0013] Furthermore, the latch is fixedly installed on the lock housing cover plate.
[0014] Furthermore, the emergency cabinet lock assembly also includes an anti-pry sleeve, which is fixedly installed on the cabinet frame through the pry bar and extends into the cabinet door from the frame.
[0015] When the door is closed, the anti-pry sleeve prevents the pry bar from being pried open through the gap between the cabinet door and the frame.
[0016] Furthermore, sealing strips are installed around the cabinet doors.
[0017] Sealing strips are used to seal the gaps between cabinet doors and frames.
[0018] Furthermore, the cabinet is also equipped with a comprehensive control box, a power distribution socket, and an air conditioner, and the lock control board is installed inside the comprehensive control box.
[0019] The power distribution frame provides power to air conditioners, IT loads, and smart terminals, while the air conditioner provides cooling to the IT loads.
[0020] This utility model also provides an emergency cabinet lock assembly, characterized in that it includes an electromagnetic spring-loaded lock, a lock body mounting plate, a rotating shaft, a lever, and a push-out lock. The lock body mounting plate is used for fixed installation on the cabinet frame. The spring-loaded lock body and rotating shaft of the electromagnetic spring-loaded lock are both fixedly installed on the lock body mounting plate. The push-out lock is used for fixed installation on the cabinet door. The lever is rotatably installed on the rotating shaft, with one end of the lever located above the vertical latch of the push-out lock and the other end located above the electromagnetic cylinder of the electromagnetic spring-loaded lock. The electromagnetic cylinder is installed on the inner side of the upper part of the spring-loaded lock body. A latch cooperating with the spring-loaded lock body is used for fixed installation on the cabinet door. The spring-loaded lock body also has an elastic push rod.
[0021] Furthermore, the emergency cabinet lock assembly also includes an anti-pry sleeve, which is used to pass through the pry bar and be fixedly installed on the cabinet frame. The thickness of the anti-pry sleeve is sufficient to allow the cabinet door to be inserted from the frame when it is closed.
[0022] The beneficial effects of this utility model are as follows:
[0023] In addition to enabling conventional password unlocking, it can also achieve automatic unlocking at high temperatures through the linkage of temperature sensor, data collector, smart terminal, lock control board, and electromagnetic spring unlocking. In case of emergency power failure, i.e. when the electromagnetic cylinder cannot be driven by an electrical signal, the emergency key can be used to rotate the lock cylinder of the ejector lock, causing the vertical lock tongue of the ejector lock to rotate the lever and press down the electromagnetic cylinder of the electromagnetic spring unlocking, thereby achieving manual emergency unlocking.
