Detailed Description

The present invention will be more clearly and completely described in the following detailed description of the preferred embodiments in conjunction with the accompanying drawings.

Fig. 1-3 show a double aviation plug interlocking device applied to a switch cabinet, wherein a movable circuit breaker handcart is arranged in the switch cabinet, and the circuit breaker handcart has two stations of testing and working. Be applied to two aviation plug interlock of cubical switchboard including: a fixed plate 100, a socket 200, two aviation plugs 300, two swing brackets 400 and two bent rods 500. The fixing plate 100 is used for fixing to a switch cabinet, and two elongated holes 110 arranged in a vertical direction are formed in the fixing plate 100. The socket 200 is fixed on the fixing plate 100, the two strip holes 110 are located on the same side of the socket 200, and the two aviation plugs 300 are arranged along the vertical direction and inserted into the socket 200. The two swing brackets 400 are located at the inner side of the fixing plate 100 and are arranged in the vertical direction, each swing bracket 400 is rotatably connected to the fixing plate 100, the lower ends of the two swing brackets 400 are rotatably connected to both ends of the connecting rod 600, the lower end of the swing bracket 400 located below extends to the lower side of the fixing plate 100, and one end of each of the two bending rods 500 passes through the two elongated holes 110 and is fixed to the two swing brackets 400. When the circuit breaker handcart is positioned at a working station, the circuit breaker handcart pushes the lower end of the swing bracket 400 upwards, and the other ends of the two bent rods 500 are arranged right above the two aviation plugs 300 and are connected with the two aviation plugs 300 in parallel; when the circuit breaker handcart is located at the test station, the circuit breaker handcart is separated from the lower end of the swing bracket 400, and the other ends of the two bent rods 500 avoid the positions right above the two aviation plugs 300 and are unlocked.

This device mainly used prevents that the circuit breaker handcart from being in operating condition, and the aviation plug 300 that connects on the circuit breaker handcart is unexpected to drop, leads to the incident. When the device is used, firstly, the two aviation plugs 300 are inserted into the socket 200, and then the circuit breaker handcart is pushed upwards and placed in a working station. At this time, the top of the circuit breaker handcart pushes the lower end of the swing bracket 400 located below upwards, so that the swing bracket 400 located below rotates, and the swing bracket 400 located above rotates simultaneously under the action of the connecting rod 600, so that the two bent rods 500 swing along the extending direction of the elongated hole 110. The other ends of the two bent rods 500 are arranged right above the two aviation plugs 300 to prevent the aviation plugs 300 from falling off the socket 200. When the circuit breaker handcart is in a test state, under the action of gravity of the swing bracket 400 and the connecting rod 600, the two bent rods 500 return to the initial positions, the aviation plug 300 can be avoided, and the fact that the aviation plug 300 is pulled out from the socket 200 cannot be influenced.

In order to prevent that the circuit breaker handcart from upwards pressing the lower extreme of swing support 400, both frictional force are too big to lead to the card to die, and in this scheme, gyro wheel 700 is installed to the lower extreme of swing support 400 that is located the below, and gyro wheel 700 is used for with circuit breaker handcart looks butt. The roller 700 can reduce the friction between the two, and avoid the occurrence of jamming.

In this embodiment, the swing bracket 400 is connected to the fixing plate 100 by a spring 800, and the spring 800 is used to return the bending rod 500 to the unlocking position. Spring 800 can ensure that wobble bracket 400 effectively resets, avoiding the occurrence of accidents that lead to the inability to disengage the interlock.

In order to ensure the accurate position of the bent rod 500 during operation, when the circuit breaker handcart is located at two stations, each bent rod 500 abuts against two ends of each elongated hole 110 respectively. The two ends of the elongated hole 110 play a role in limiting.

In this embodiment, each swing bracket 400 has two coaxial connecting holes 410, the two connecting holes 410 are rotatably connected to the fixing plate 100, and the curved rod 500 is fixed between the two connecting holes 410. The two connecting holes 410 are rotatably connected to the fixing plate 100, so that the connection strength between the swing bracket 400 and the fixing plate 100 can be improved, and the swing bracket 400 is prevented from being deformed by a force.

Although specific embodiments of the present invention have been described above, it will be understood by those skilled in the art that this is by way of example only, and that the scope of the invention is defined by the appended claims. Various changes and modifications to these embodiments can be made by those skilled in the art without departing from the spirit and the principles of the present invention, and these changes and modifications are all within the scope of the present invention.
