Description

Mounting base for mechanical interlocking lock and use method thereof

Technical Field

The invention relates to the field of related power distribution electrical equipment, in particular to a mounting base for a lock for a mechanical interlocking and a use method thereof.

Background

The high-current socket is commonly used for shore power electric equipment in ports and docks or large factories, and the shore power electric equipment is in an open environment in many cases, so that certain potential safety hazards are brought to the power utilization environment of the shore power electric equipment, and the potential safety hazards existing in the shore power electric equipment are more obvious particularly on some contact electric equipment.

Therefore, the electric safety of the shore power electric equipment is troublesome, and the mounting base of the mechanical interlocking lock is provided for ensuring that a plug and a socket in the shore power electric equipment are safely used during power transmission.

Disclosure of Invention

The invention aims to provide a mounting base of a mechanical interlocking lock, which is used on a high-current socket and matched with an industrial lock and is mainly used for mechanical interlocking in a plug-socket plugging state.

In order to realize the invention, the following technical scheme is adopted: the mounting base for the lock for the mechanical interlocking comprises a base main body, a socket seat, an industrial lock and an auxiliary push arm; the base main body is internally provided with a movable pin and a movable push rod, the base main body is fixed on the socket seat, the movable pin is sleeved with a spring and is fixed on the base main body by a nut, and the industrial lock is arranged on the base main body; one end of the movable push rod is provided with a circle of semicircular groove, and the groove corresponds to the popping position of the movable tongue of the industrial lock in the base main body when in use.

Further, the base body is provided with a movable tongue hole corresponding to the industrial lock.

Further, the auxiliary pushing arm is provided with a movable pin hole.

Further, when the movable push rod is not used, the movable pin is in a retracted state under the action of the spring, the movable pin limits the ejection of the movable tongue of the industrial lock, and the key of the industrial lock cannot be pulled out.

Further, the movable push rod is connected with the plug through a chain.

When the movable push rod is not used, the movable pin is in a retracted state under the action of the spring. At this time, the movable pin restricts the ejection of the movable tongue of the industrial lock, and the key of the industrial lock cannot be pulled out.

The use method of the mounting base for the lock for the mechanical interlocking is that when a plug and a socket are inserted, when a movable push rod drives a movable pin to push forward and eject, the movable pin is inserted into a hole on an auxiliary push arm of the socket to lock the socket. A round semicircular groove is reserved on the movable push rod, and in this state, the movable tongue of the industrial lock can be ejected to lock the movable push rod, so that the key can be pulled out smoothly. Similarly, the key is inserted, the industrial locking tongue is rebounded by rotation, the movable push rod is ejected by the retracted movable pin under the action of the spring, and the plug and the socket can be separated.

The auxiliary pushing arm has only one hole and is aligned with the movable pin hole on the base main body only when the plug and the socket are in the inserted state. The movable pin is blocked in other states, so that the movable pin is prevented from being driven in the non-plug socket plugging state, and the key of the industrial lock is unlocked.

The movable push rod is connected with the plug by a chain, and the movable push rod is used for confirming that the plug is inserted into the socket.

The key of the industrial lock and the key of the power transmission machine room are the same key, so that the plug and the socket are inserted completely when power is transmitted.

The key of the industrial lock is not used, the movable push rod cannot be pulled out, the movable pin cannot rebound, and the plug and the socket cannot be separated. The industrial lock can be pulled out only when the movable tongue is in a pop-up state. When the movable tongue is in a retracted state, the key cannot be pulled out. This ensures that the plug and socket are disconnected and in a power-off state.

The beneficial effects are that: the base is used for ensuring that a plug and a socket are plugged when power is transmitted and cannot be separated when power is transmitted; when the plug and socket separation operation is carried out, the plug and the socket are in a power-off state, so that the mechanical interlocking is realized. When the key is inserted, the machine room can transmit power to the socket, and when the key is pulled out, the machine room cuts off the power to the socket.
