Technical Field
[0001] The utility model relates to the technical field of ring network cabinets, in particular to an environmentally friendly gas ring network cabinet with a handle operation interlock. Background Art
[0002] At present, various ring network cabinets are widely used in distribution stations at all levels in urban and rural areas. Existing pneumatic ring network cabinets are generally not equipped with handle operation interlocks. When operating, if the construction workers forget to unplug the manual operation handle, and other construction workers remotely operate the ring network cabinet, it will cause the mechanism parts to collide with the operation handle, causing the mechanism to get stuck or even scrapped, thus delaying the construction period and requiring the ring network cabinet to be repaired again, increasing costs. Therefore, there is an urgent need for a ring network cabinet with handle operation interlocks that will not be misoperated. Summary of the invention

[0013] See also Figure 1-2 The present embodiment is an environmentally friendly gas ring network cabinet with a handle operation interlock, comprising a cabinet body, an isolation mechanism 1 is installed at the upper end of the cabinet body, a circuit breaker mechanism 9 is installed at the lower end, the circuit breaker mechanism 9 is provided with a closing plate 8, a cabinet door is provided on one side of the cabinet body, and an operation hole 5 is provided on the cabinet door corresponding to the isolation mechanism 1, and the operation hole 5 is used to insert an operating handle to operate the isolation mechanism 1; an isolation interlocking plate 2 is provided on the inner side of the cabinet door, and the isolation interlocking plate 2 is slidably connected with the cabinet door along the vertical direction, and a blocking portion A21 is provided on the isolation interlocking plate 2 corresponding to the operation hole 5, and a circuit breaker interlocking plate 7 is installed at the bottom of the isolation interlocking plate 2, and a blocking portion B71 is provided on the circuit breaker interlocking plate 7 corresponding to the closing plate 8; a reset spring 6 is installed on the cabinet door, and the reset spring 6 is connected to the isolation interlocking plate 2, and the reset spring 6 is used to reset the isolation interlocking plate 2 and the circuit breaker interlocking plate 7 to the blocking operation hole 5 and the closing plate 8, and a waist-shaped hole arranged along the vertical direction is provided on the cabinet door, and the isolation interlocking plate 2 is provided with a sliding portion extending outward from the waist-shaped hole.
[0014] Furthermore, a guide waist-shaped hole is provided at one end of the circuit breaker interlocking plate 7, and a connecting pin 22 is fixedly provided at the bottom of the isolation interlocking plate 2. The connecting pin 22 is slidably connected to the circuit breaker interlocking plate 7 in the guide waist-shaped hole. A fixing pin 10 is provided in the cabinet door. A point on the circuit breaker interlocking plate 7 is rotatably connected to the fixing pin 10. The blocking part B71 is driven to rotate by the up and down movement of the isolation interlocking plate 2 to achieve blocking or unlocking of the closing plate 8.
[0015] Furthermore, the reset spring 6 is a tension spring, one end of which is fixedly connected to the cabinet door, and the other end of which is fixedly connected to a point on the isolation interlocking plate 2.
[0016] Furthermore, a guide pin 4 is provided on the inner side of the cabinet door, and a guide groove 3 arranged along the vertical direction is provided on the isolation interlocking plate 2 corresponding to the guide pin 4, so that the isolation interlocking plate 2 can be moved along the vertical direction through the guide pin 4.
[0017] Furthermore, the isolation mechanism 1 is provided with two operating holes 5, and the isolation interlocking plate 2 is provided with blocking parts A21 corresponding to the two operating holes 5. The working principle of the utility model is as follows: when the operating handle needs to be inserted, the isolation interlocking plate 2 is first driven downward by the sliding part to expose the operating hole 5, and then the operating handle is inserted into the operating hole 5, and the operating handle holds the isolation interlocking plate 2 so that it cannot be reset. When the isolation interlocking moves downward, the connecting pin 22 drives the circuit breaker interlocking plate 7 to rotate downward with the fixing pin 10 as the axis until the blocking part B71 at the bottom of the circuit breaker interlocking turns to the closing plate 8.
[0018] In this case, when the circuit breaker closing button is pressed, the circuit breaker closing plate 8 rotates to the upper right. Since the circuit breaker is interlocked above the circuit breaker closing plate 8, the closing plate 8 is blocked, thereby limiting the closing of the circuit breaker and protecting the left and right.
[0019] On the contrary, when the operating handle is pulled out, the tension spring rebounds due to its own elastic force to drive the isolation interlocking plate 2 to move upward and reset, thereby driving the circuit breaker interlocking plate 7 to rotate upward to open and close the gate plate 8, and the circuit breaker can now perform a closing operation.
