Description

Technical Field

[0001] The invention relates to the technical field of busbar plug-in boxes, in particular to a plug-in box with a locking door lock interlock. Background Art

[0002] The plug-in box is equivalent to the cable branch joint. A plug-in box is required to draw power from the bus duct. The plug-in box has a built-in circuit breaker. The installation method of the plug-in box is as follows: Before installing the plug-in box, the safety baffle at the bus duct socket should be opened. The switch in the box should be pushed to the OFF position first, and the plug-in box pins should be inserted into the bus duct from the bus duct socket according to the phase sequence, and ensure that they are inserted in place. It is forbidden to plug and unplug with power on. After the plug-in box is installed, the claw-shaped card plates at the front and back should be fixed on both sides of the bus duct and the screws should be tightened. For the plug-in box with a built-in circuit breaker, when it is installed vertically, a load-bearing support arm should be installed at the bottom; when it is installed horizontally, a load-bearing hoop should be installed. The plug-in box is only responsible for leading the point from the bus duct to the required place. There is a switch in the plug-in box. At the same time, one end of the plug-in box is inserted into the bus duct, and the other end is connected to the cable, and then the cable is connected to the floor distribution box.

[0003] A plug-in box with a locking door lock interlock in the prior art cannot lock or unlock the bottom of the plug-in box and the busbar, which is inconvenient for staff to operate and is prone to misoperation. The safety of the plug-in box is relatively low, the door lock interlock does not have an unlocking function, and the box door cannot be automatically controlled to open and close.

[0004] Therefore, it is urgent to design a plug-in box with a locking door lock interlock to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a plug-in box with a locking door lock interlock.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A plug-in box with a locking door lock interlock comprises a plug-in box, the plug-in box comprises a bus duct and a box body, a guide groove is opened at the top of the bus duct, a first plug-in box lock and a second plug-in box lock are arranged at the top of the bus duct, a support plate is arranged at the top of the bus duct, a mounting hole is opened at the top of one side of the support plate, a bus locking interlock is arranged at the top of the bus duct, and the bus locking interlock is plugged into the inside of the mounting hole, a connecting rod is arranged at the top of the support plate, a locking device interlock mechanism is arranged at one end of the connecting rod, and a circuit breaker interlock is arranged at the top of the connecting rod, a side plate is arranged at one side of the bus duct, the top of the box body is connected to a box cover by a hinge rotation, a door lock interlock is arranged on one side of the box cover, and a rectangular groove is opened on one side of the box cover.

[0008] Furthermore, the busbar locking interlock and the circuit breaker interlock are mutually limited, a limit is set between the circuit breaker interlock and the door lock interlock, and an unlocking mechanism is arranged inside the door lock interlock.

[0009] Furthermore, a plurality of wiring phase rows and a PE phase row are arranged on the top of the support plate, and the plurality of wiring phase rows are sequentially arranged side by side.

[0010] Furthermore, the support plate and the circuit breaker interlock are both arranged inside the box, and the circuit breaker interlock is clamped on the support plate.

[0011] The beneficial effects of the present invention are:

[0012] 1. Through the busbar locking interlock, the busbar locking interlock is fixed at the bottom of the box and can rotate around the fixed axis hole. The bottom of the plug-in box can be locked or unlocked with the busbar, which is convenient for the staff to operate and improve work efficiency.

[0013] 2. Through the circuit breaker interlock, when the circuit breaker is closed, the circuit breaker interlock moves upward to support the busbar locking interlock, so that it cannot rotate, unlock the lock with the busbar, and at the same time embed into the door lock interlock mechanism, so that the door cover of the plug-in box cannot be opened, preventing staff from operating incorrectly and improving the safety of the plug-in box.

[0014] 3. Through the door lock interlock, when the circuit breaker is closed, the door lock interlock can limit the opening of the door cover of the plug-in box. When the circuit breaker fails and cannot be opened, the door lock interlock has an unlocking function, which is convenient for automatic control of the opening and closing of the box door.
