Abstract
A switch cabinet rear cover plate locking mechanism comprises a switch cabinet body and a rear cover plate. The switch cabinet body is internally provided with a switch cabinet large shaft. The rear cover plate is provided with a lock pin. One end of the lock pin is provided with a spring bolt while the other end of the lock pin is provided with a boss. The end part of the switch cabinet large shaft is provided with a groove, and the spring bolt is plugged into the groove. The locking pin and the switch cabinet large shaft are connected through a bolt. According to the switch cabinet rear cover plate locking mechanism of the utility model, the lock pin is mounted on the switch cabinet large shaft. When a ground switch is closed, the lock pin rotates along with the large shaft and the spring bolt is aligned with an opening of the rear cover plate. For the time being, the rear cover plate can be disassembled, thereby being beneficial for maintenance. When the ground switch is opened, the lock pin rotates along the switch cabinet large shaft for 180 degrees and the spring bolt locks the rear cover plate. When an operation mechanism of the ground switch has a fault, the lock pin can be disassembled and then the rear cover plate can be opened.
Description
Technical field
the utility model relates to switch cubicle technical field, specifically a kind of switch cubicle back shroud retaining mechanism.
Background technology
operating personnel, in the time of inspection switch cabinet, can close a floodgate earthed switch, and the switch cubicle back shroud of then dismantling carries out correlation test and maintenance.In the time of the charging operation of switch cabinet main loop, earthed switch, in gate-dividing state, does not now allow to open switch cubicle back shroud, otherwise has Danger Electric shock risk, only has in the time that earthed switch closes a floodgate, and just allows to open switch cubicle back shroud, to ensure operating personnel's safety.When earthed switch is in "on" position and earthing switch operating mechanism breaks down cannot open back shroud time, there is no the mechanism that can open back shroud of other standby, can affect maintenance or test progress.
Utility model content
Technical problem to be solved in the utility model is to provide the one can be at earthed switch in "on" position, and earthing switch operating mechanism fault be cannot open back shroud time, can be used as reserved regimen and open the switch cubicle back shroud retaining mechanism of switch cubicle back shroud.
The utility model solves its technical problem by the following technical solutions.
A kind of switch cubicle back shroud retaining mechanism, comprises switch cubicle and back shroud, is provided with switch cubicle macro-axis in described switch cubicle, and the large shaft end of described switch cubicle is provided with lock pin, and described lock pin is through back shroud; Described lock pin one end is provided with dead bolt, and described dead bolt is pressed in described back shroud outside.
The large shaft end of described switch cubicle is provided with groove, and the described lock pin other end is provided with boss, and described boss inserts in described groove; Described lock pin and described switch cubicle macro-axis are bolted.
Described back shroud is provided with the hole corresponding with the dead bolt shape of lock pin, and described lock pin is bolted through hole and switch cubicle macro-axis.
A kind of switch cubicle back shroud retaining mechanism of the present utility model, lock pin is arranged on switch cubicle macro-axis, and when earthed switch closes a floodgate, lock pin rotates with macro-axis, and the perforate of its dead bolt and back shroud aligns, and now back shroud can be dismantled, easy access; In the time of grounding switch tripping, lock pin rotates 180 degree with switch cubicle macro-axis, and dead bolt can pin back shroud; After breaking down back shroud cannot open time, can pull down lock pin, earthing switch operating mechanism opens back shroud.
Brief description of the drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is back shroud open mode schematic diagram;
Fig. 3 is the structural representation of lock pin.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of switch cubicle back shroud retaining mechanism, comprises switch cubicle 1 and back shroud 2, and switch cubicle macro-axis 3 is installed in switch cubicle 1, and switch cubicle macro-axis 3 ends have groove 7; Switch cubicle macro-axis 3 ends are provided with lock pin 4, have the hole 10 corresponding with dead bolt 5 shapes of lock pin 4 on back shroud 2, and lock pin 4 is connected by bolt 8 with switch cubicle macro-axis 3 through hole 10; There is dead bolt 5 lock pin 4 one end, and dead bolt 5 is pressed in back shroud 2 outsides, and lock pin 4 other ends have boss 6, in boss 6 insertion grooves 7.
Boss 6 coordinates with the groove 7 on switch cubicle 3, makes switch cubicle macro-axis 3 in rotation process, be with pendulum lock pin 4 synchronously to rotate; In the time that the dead bolt 5 of lock pin 4 turns to top, the hole 10 on back shroud 2 is corresponding with the position of dead bolt 5, now can open back shroud 2; When dead bolt 5 turns to lock pin 4 belows, dead bolt 5 staggers with the hole 10 of back shroud 2, now for locking the state of back shroud 2; When operating mechanism breaks down, when switch cubicle macro-axis 3 can not be rotated, can pull down bolt 8, then take off lock pin 4, can pull down back shroud 2.
Claims (1)
1. a switch cubicle back shroud retaining mechanism, comprises switch cubicle and back shroud, is provided with switch cubicle macro-axis in described switch cubicle, and the large shaft end of described switch cubicle is provided with lock pin, and described lock pin is through back shroud; Described lock pin one end is provided with dead bolt, described dead bolt is pressed in described back shroud outside, it is characterized in that: described switch cubicle macro-axis (3) end is provided with groove (7), described lock pin (4) other end is provided with boss (6), and described boss (6) inserts in described groove (7); Described back shroud (2) is provided with the hole (10) corresponding with dead bolt (5) shape of lock pin (4), and described lock pin (4) is connected by bolt (8) with switch cubicle macro-axis (3) through hole (10).
