1. Field of the Invention
The present invention relates to a lock assembly structure, particularly to a complex lock assembly structure having a dual unlocking mechanism, applicable to a valve chamber, a gas cylinder cabinet or a large door, and convenient for maintenance.
2. Description of the Prior Art
With fast advance of science and technology, electronic lock devices have been widely accepted and extensively used. Nowadays, many lock devices involve electronic elements, such as motor actuators, sensors and controllers. However, the lock devices using motor actuators are likely to generate sparks and may cause fire or gas explosion while they are applied to valve chambers administering special gases (such as combustible gases, inflammable gases and combustion assistant gases) or exposed to an environment having these special gases.
Thus are generated the lock devices using pneumatic actuators or hydraulic actuators to replace motor actuators. For a conventional lock device using a pneumatic or hydraulic actuator, the pneumatic or hydraulic actuator is normally encapsulated inside the lock device. Once the pneumatic or hydraulic actuator malfunctions, the actuator cannot be repaired unless the entire lock device is dismounted and dismantled. Besides, while an electronic lock device malfunctions, the lock device would entirely fail to work and make the door unlikely to open or lock. In such a case, the electronic lock device must be dismounted and disassembled instantly. Dismounting or disassembling the electronic lock device is likely to generate sparks and also likely to cause leakage of gases if the electronic lock device is applied to a special environment, such as a gas cylinder cabinet. Therefore, dismounting or disassembling an electronic lock device applied to an environment having special gases has a high risk in industrial safety.
Accordingly, the present invention proposes a novel complex lock assembly structure to overcome the important problem.
One objective of the present invention is to provide a complex lock assembly structure enabling the user to maintain it easily and unlock it by hands and by the pressure-cylinder actuator.
To achieve the abovementioned objective, the present invention proposes a complex lock assembly structure, which comprises a body whose front has a frame; a pressure-cylinder actuator disposed on and exposed from a back of the body; a door fastener disposed on and exposed from the back of the body, having an interlocking relationship with the pressure-cylinder actuator; and a mechanical lock disposed inside the frame on the front of the body, controlling and limiting movement of the door fastener.
In one embodiment, the mechanical lock includes a lock head; a blocking plate whose locking function can be enabled or disabled by a key inserted into the lock head; a first elastic element disposed in the bottom of the frame; and a door handle, wherein the door handle and the first elastic element actuate each other, and wherein the first elastic element is used to restore the door handle to a preset position, and wherein the blocking plate is used to limit movement of the door handle, and wherein while the locking function of the blocking plate is disabled, opening the door handle actuates the action of the door fastener.
In one embodiment, at least one opening is formed in the bottom of the frame to facilitate movement of the door handle and the door fastener.
In one embodiment, the pressure-cylinder actuator is a pneumatic actuator or a hydraulic actuator.
In one embodiment, the pressure-cylinder actuator includes an interlocking assembly coupled to the door fastener for interlocking operations.
In one embodiment, the door fastener includes a latch and a latch connection element, which are connected by at least one screw assembly or fabricated into a one-piece component.
In one embodiment, the interlocking assembly is connected with the latch connection element by at least one screw assembly.
In one embodiment, the door handle includes a door handle connection element used to install the door handle in the body.

The complex lock assembly structure of the present invention is characterized in integrating a pressure-cylinder lock and a mechanical lock and arranging the pressure-cylinder actuator and the mechanical lock respectively in the exterior and interior of the lock assembly structure to acquire the advantages of both. While power is interrupted or the pressure-cylinder actuator fails, the complex lock assembly structure can still use the mechanical lock to maintain the functions of locking and unlocking the door without being dismantled or repaired instantly. Thus is exempted from the danger caused by the failure of the lock. Therefore, the complex lock assembly structure only needs disassembling and maintaining on the scheduled dates. Besides, as the pressure-cylinder actuator is disposed on the exterior of the lock assembly structure, it is easy to replace and convenient to repair. Thus, the overall values of the present invention are to effectively increase the safety of usage and maintain the continuous operation of equipment.
In summary, the present invention provides a complex lock assembly structure enabling the user to maintain it easily and unlock it by hands and by the pressure-cylinder actuator.
