Description

Solid Insulated Cabinet Door Interlocks with Emergency Release

technical field

The utility model relates to a cabinet door interlocking device, mainly a solid insulation cabinet door interlocking device with an emergency unlocking function.

Background technique

At present, the door interlocking structure of complete sets of cabinets such as solid insulated cabinets and inflatable ring network cabinets does not have an emergency unlocking function, and the interlocking structure of some cabinets is complicated and unreliable. It is difficult to open the cabinet door when the interlock fails. It is inconvenient for maintenance and problem solving, but the utility model has simple structure, reliable interlock and emergency unlocking function, which can solve existing problems and provide convenience for equipment maintenance, reduce maintenance and power outage time losses to users.

Utility model content

The technical problem to be solved by the utility model is to provide a solid insulating cabinet door interlocking device with an emergency unlocking function, which has a simple structure, reliable interlocking, automatic reset, and an emergency unlocking function, and can be widely applied to Inflatable ring network cabinet, solid insulation cabinet.

In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:

A solid insulated cabinet door interlock device with emergency unlocking function, including a cabinet body, an isolation-grounding operation shaft is installed on the upper part of the cabinet body, and a cabinet door with holes is arranged on the lower part of the cabinet body. The door-shaped bracket is fixed and installed on the bottom plate of the instrument room by bolts, and the door-shaped bracket and the bottom plate of the instrument room are respectively provided with corresponding holes; a T-shaped boss locking rod is also included, and the T-shaped boss locking rod passes through the door. The hole on the bottom plate of the type bracket and the instrument room extends downwards, and the bottom of the T-shaped boss locking lever is connected with an emergency unlocking lever through a screw thread, and the emergency unlocking lever extends downward to the cabinet door, and the T-shaped boss locking lever The upper part of the spring is set with a spring, the upper end of the spring is against the top of the T-shaped boss locking lever, the lower end of the spring is against the door-shaped bracket, and a cam is installed on the isolation-grounding operation shaft and fastened with screws. The cam rotates and presses on the top of the T-shaped boss locking lever, the T-shaped boss locking lever moves downward, and the emergency release lever connected to the bottom of the T-shaped boss locking lever moves downward and is inserted into the small hole on the cabinet door.

The described interlocking device for solid insulated cabinet doors with emergency unlocking function is characterized in that: a limit pin is installed on the T-shaped boss interlocking rod at a position inside the door-shaped bracket, and the length of the limit pin is longer than that of the cabinet. The size of the hole in the instrument compartment floor of the body.

The described door interlocking device of a solid insulation cabinet with emergency unlocking function is characterized in that the hole corresponding to the door-shaped bracket and the bottom plate of the instrument room is a square hole, and the corresponding T-shaped boss interlocking rod is Square rod.

The working principle of the utility model is:

Turning the isolation-grounding operating shaft drives the cam to rotate, the cam presses on the T-shaped boss locking lever and moves it downward, thereby compressing the spring, and at the same time the T-shaped boss locking lever moves down to drive the emergency release of the threaded connection at the bottom The rod moves down and is inserted into the small hole of the cabinet door to realize interlocking. If the interlock fails, you can use a special tool to rotate the emergency unlocking lever to separate it from the T-shaped boss locking lever. Because the hole diameter on the cabinet door is larger than the maximum diameter of the emergency unlocking lever, it will fall into the cabinet door after detachment. At this time, there is no interlocking rod on the top to go deep into the hole of the cabinet door, and the cabinet door can be beaten. The structure of the cabinet door is a hanging type, and it is necessary to lift the cabinet door upwards for a certain distance to take out the cabinet door.

The utility model has the advantages of:

The utility model has simple structure, reliable interlocking, automatic reset, and emergency unlocking function, and can be widely applied to inflatable ring network cabinets, solid insulation cabinets, or devices with the cabinet door structure described in the utility model.
