Detailed Description
The technical solution of the present invention will be further described with reference to the accompanying drawings and the detailed description.
The utility model discloses a switching-on and switching-off sequential action interlocking structure, which comprises an incoming cabinet lock 1 positioned on an incoming cabinet and an outgoing cabinet lock 2 positioned on an outgoing cabinet, wherein the incoming cabinet lock and the outgoing cabinet lock share one key; the incoming line cabinet lock 1 and the outgoing line cabinet lock 2 are both provided with a program lock locking plate 4 and a travel switch locking plate 5, and a travel switch 6 is arranged on the program lock bracket 3; the incoming line cam sheet 7 of the incoming line cabinet lock 1 and the outgoing line cam sheet 8 of the outgoing line cabinet lock 2 are respectively sleeved on the corresponding load switch opening and closing operation shafts. Wherein, the incoming line cabinet lock 1 is in a locking state, and the key can be pulled out; the incoming line cabinet lock 1 is in an unlocking state, and a key cannot be pulled out. The outlet cabinet lock 2 is in a locked state, and a key can be pulled out; the outlet cabinet lock 2 is in an unlocked state, and the key cannot be pulled out. The inlet cam piece 7 is a movable fan-shaped structure, and the side part of the inlet cam piece 7 is provided with a gap structure. The outgoing cam sheet 8 is in a movable fan-shaped structure.
When the device is used, the travel switch locking plate 5 and the program lock locking plate 4 are arranged on the program lock, the program lock and the travel switch 6 are fixed on the program lock bracket 3, and the incoming line cam plate 7 and the outgoing line cam plate 8 are respectively sleeved on the load switch opening and closing operation shaft.
After the incoming line cabinet is switched on, the program lock is locked (the key can be pulled out), the key is pulled out, the program lock locking plate 4 blocks the operating hole at the moment, the operating handle is forbidden to be inserted, the incoming line cam plate 7 is an upper-gear three-in two-interlocking locking plate, a groove is formed in the lower portion, and the lower program lock can be allowed to be locked, as shown in fig. 1 and 2. The key pulled down from the incoming line cabinet is inserted into the outgoing line cabinet program lock, the program lock is unlocked, the program lock locking plate 4 is driven to move, the operation hole is exposed, the operation handle is inserted for switching on, the outgoing line cam plate 8 abuts against the program lock locking plate 4 after switching on, the program lock is always in an unlocking state, and the key cannot be pulled out, as shown in fig. 3 and 4. The sequential action of firstly closing the incoming line cabinet and then closing the outgoing line cabinet is achieved, and at the moment, the key is positioned on the closing position of the outgoing line cabinet, and the key cannot be pulled out, so that the incoming line cabinet cannot be opened. To operate the incoming cabinet opening, the outgoing cabinet must be opened first, as shown in fig. 5 and 6; the operating handle is inserted to operate the wire outlet cabinet to open the brake, at the moment, the cam sheet 8 of the wire outlet cabinet faces to the right, the key can act, the program lock is locked, and the key is pulled out.
