Abstract
The utility model discloses an automatic electrification locking device for a switch cabinet. The automatic electrification locking device comprises a grounding switch operation hole, a grounding control mechanism and an electromagnetic lock which are arranged on a switch cabinet panel, wherein the grounding control mechanism comprises a bearing, a center rotating shaft, a limiting plate and a spring pull rod; the center rotating shaft is arranged in the bearing in a rotatable manner; the baffle plate is connected with one end of the center rotating shaft; the other end of the center rotating shaft is provided with the limiting plate; one end of the spring pull rod is connected to the outer end of the limiting plate, and the other end of the spring pull rod is connected to the switch cabinet panel; and the electromagnetic lock is controlled by an electrification state of the wire inlet side of the switch cabinet to indirectly control a baffle plate to open or close the grounding switch operation hole. According to the automatic electrification locking device, the baffle plate can close the grounding switch operation hole when the wire inlet side of the switch cabinet is electrified; and the automatic electrification locking device has a simple structure, is convenient to mount and debug, and is suitable for various switch cabinets.
Description
Technical field
The utility model relates to a kind of locking device that is used for switch cubicle, is specially the charged self-locking gear of a kind of switch cubicle.
Background technology
Switch cubicle is a kind of electrical control equipment, and switch cubicle when switch cubicle inlet wire side is charged, does not allow the earthed switch in the cabinet to close a floodgate in running.For satisfying above-mentioned requirements, switch cubicle adopts online tool or electric locking device in the prior art.In actual use, because these apparatus structures are complicated, therefore complex operation is complicated when installation, debugging, and operational reliability also is difficult for guaranteeing.
The utility model content
The purpose of the utility model provides the charged self-locking gear of a kind of switch cubicle, with solve in the prior art locking device because of complex structure install, complex operation is complicated during debugging, and operational reliability also is difficult for the problem that guarantees.
For reaching said purpose, the technical scheme that the utility model adopts is:
The charged self-locking gear of a kind of switch cubicle; Include the earthed switch handle hole, ground connection controlling organization and the electromagnetic lock that are arranged on the switch cabinet panel; It is characterized in that: said earthed switch handle hole inboard is provided with baffle plate; Said ground connection controlling organization includes bearing, central rotating shaft, limiting plate and spring pull bar, and said central rotating shaft is rotatably installed in the bearing, and said baffle plate is fixedly connected on the end of central rotating shaft; The other end of said central rotating shaft is equipped with limiting plate, and said baffle plate can open or close the earthed switch handle hole with the central rotating shaft swing; One end of said spring pull bar is connected on the limiting plate outer end, and the other end of said spring pull bar is connected on the switch cabinet panel; Said electromagnetic lock includes dead bolt; Said dead bolt and electromagnetic lock are slidingly connected; Said electromagnetic lock is controlled by switch cubicle inlet wire side electriferous state, and promptly electromagnetic lock when energising dead bolt stretches out and keep off on the limiting plate rotary motion trace, dead bolt indentation and get out of the way the rotary motion trace of limiting plate when electromagnetic lock cuts off the power supply.
The charged self-locking gear of described a kind of switch cubicle is characterized in that: said central rotating shaft can drive baffle plate when rotating and limiting plate moves together, manually retracts baffle plate when resetting and gets final product.
The beneficial effect of the utility model is:
Baffle plate can be closed the earthed switch handle hole when the utility model can guarantee effectively that switch cubicle inlet wire side is charged, and the utility model is simple in structure, and Installation and Debugging are convenient, are applicable to multiple switch cubicle.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
As shown in Figure 1; The utility model includes earthed switch handle hole 2, ground connection controlling organization 3 and the electromagnetic lock 4 that is arranged on the switch cabinet panel 1; Earthed switch handle hole 2 inboards are provided with baffle plate 7; Ground connection controlling organization 3 includes bearing 5, central rotating shaft 6, limiting plate 8 and spring pull bar 10, and central rotating shaft 6 is rotatably installed in the bearing 5, and baffle plate 7 is fixedly connected on the end of central rotating shaft 6; The other end of central rotating shaft 6 is equipped with limiting plate 8, and baffle plate 7 can open or close earthed switch handle hole 2 with central rotating shaft 6 swings; One end of spring pull bar 10 is connected on limiting plate 8 outer ends, and the other end of spring pull bar 10 is connected on the switch cabinet panel 1; Electromagnetic lock 4 includes dead bolt 9; Dead bolt 9 is slidingly connected with electromagnetic lock 4; Electromagnetic lock 4 is controlled by switch cubicle inlet wire side electriferous state, i.e. dead bolt 9 stretches out and keep off on limiting plate 8 rotary motion trace during electromagnetic lock 4 energising, dead bolt 9 indentations and get out of the way the rotary motion trace of limiting plate 8 when electromagnetic lock 4 cuts off the power supply.
Central rotating shaft 6 can drive baffle plate 7 when rotating and move together with limiting plate 8, manually retracts baffle plate 7 when resetting and gets final product.
When switch cubicle inlet wire side was charged, electromagnetic lock 4 energising control dead bolts 9 stretched out and keep off on the rotary motion trace of limiting plate 8, so central rotating shaft 6 stops operating, and baffle plate 7 is closed earthed switch handle hole 2; When switch cubicle inlet wire side was not charged, electromagnetic lock 4 no powers then dead bolt 9 were withdrawn automatically and are got out of the way the rotary motion trace of limiting plate 8, and central rotating shaft 6 rotates under the tension of spring pull bar 10 and drives baffle plate 7 opens earthed switch handle hole 2.
Claims (2)
1. charged self-locking gear of switch cubicle; Include the earthed switch handle hole, ground connection controlling organization and the electromagnetic lock that are arranged on the switch cabinet panel; It is characterized in that: said earthed switch handle hole inboard is provided with baffle plate; Said ground connection controlling organization includes bearing, central rotating shaft, limiting plate and spring pull bar, and said central rotating shaft is rotatably installed in the bearing, and said baffle plate is fixedly connected on the end of central rotating shaft; The other end of said central rotating shaft is equipped with limiting plate, and said baffle plate can open or close the earthed switch handle hole with the central rotating shaft swing; One end of said spring pull bar is connected on the limiting plate outer end, and the other end of said spring pull bar is connected on the switch cabinet panel; Said electromagnetic lock includes dead bolt; Said dead bolt and electromagnetic lock are slidingly connected; Said electromagnetic lock is controlled by switch cubicle inlet wire side electriferous state, and promptly electromagnetic lock when energising dead bolt stretches out and keep off on the limiting plate rotary motion trace, dead bolt indentation and get out of the way the rotary motion trace of limiting plate when electromagnetic lock cuts off the power supply.
