Enter the limited post in the limiting slot.
The utility model has the beneficial effects that：Since the switchgear of the utility model is by using linkage mechanism driving switch
Disconnecting switch inside cabinet or earthing switch action, therefore, user are not necessarily to stretch into the inside of the switchgear, it is only necessary to switch
The surface operation linkage mechanism of cabinet prevents user from contacing the electrical equipment of inside switch cabinet electrification by mistake, user is avoided to get an electric shock,
Ensure the life security of user.
Description of the drawings
Utility model will be further described in detail below with reference to the attached drawings and specific embodiments.
When Fig. 1 is that linkage mechanism is connected with disconnecting switch, earthing switch respectively in one preferred embodiment of the utility model
Attachment structure schematic diagram；
Fig. 2 is the structural schematic diagram of one preferred embodiment of the utility model；
Fig. 3 is the side view of one preferred embodiment of the utility model.
Specific implementation mode
Referring to figs. 1 to Fig. 3, a kind of switchgear of protection against electric shock, an including cabinet 30, the cabinet 30 be internally provided with every
Pass 20 and earthing switch 21 are left, while being additionally provided on cabinet 30 dynamic for controlling the disconnecting switch 20 and earthing switch 21
Linkage mechanism whether work, the linkage mechanism include a mounting plate 10, it is preferable that the mounting plate 10 is installed on the cabinet
30 outer surface is provided with two groups of driving mechanisms, one of which driving mechanism and the disconnecting switch 20 on the mounting plate 10
It is connected, another group of driving mechanism is connected with the earthing switch 21；The driving mechanism is rotatablely arranged at including one
Drive shaft 11 on the mounting plate 10 is provided with the swing rod 12 that it can be followed to rotate synchronously in the drive shaft 11,
The swing rod 12 is articulated with one for movable with disconnecting switch 20 or earthing switch 21 on one end far from the drive shaft 11
The connecting rod 13 being connected.
Due to the utility model switchgear by using linkage mechanism driving cabinet 30 inside disconnecting switch 20 or connect
Ground switch 21 acts, and therefore, user is not necessarily to stretch into the inside of the cabinet 30, it is only necessary in the surface operation gear of cabinet 30
Structure prevents user from contacing the internally charged electrical equipment of cabinet 30 by mistake, user is avoided to get an electric shock, and ensures the life peace of user
Entirely.
Wherein, the drive shaft 11 of the driving mechanism is driven to rotate using turning tool for the ease of user, herein,
Preferably, the inside of the drive shaft 11 offers the square hole 110 convenient for being clamped with turning tool.Therefore, user uses
