Plug-in strip and static contact are switched on or switched off, however, the complex structural designs of existing earthing switch, volume is larger, heavier-weight,
It is not convenient enough to operate, and cannot preferably protect the personal safety of operator.
Summary of the invention
The purpose of the utility model is to overcome the defect of the prior art, provide a kind of structure it is simple, it is stable and reliable for performance,
Operate box-type earthing switch convenient, small in size.
To achieve the above object, the utility model uses a kind of box-type earthing switch, including cabinet, setting are in cabinet
Switch block, the driving assembly that is arranged on cabinet and executes separating brake or feed motion for driving switch component, it is described
Switch block includes being rotatably arranged on the intracorporal main shaft of case, the plug-in strip being arranged with main shaft linkage, insulator, spring, setting exhausted
Static contact on edge, the driving assembly include the gear shaft being arranged on cabinet at corresponding main shaft, are arranged on main shaft
Drive bevel gear, the driving bevel gear that is arranged on gear shaft and is meshed with drive bevel gear, have on the gear shaft
There is the rocking handle jack extended in outside cabinet, the drive bevel gear is with the movement of driving bevel gear and can drive main axis.
The beneficial effect of above structure is: the earthing switch is provided with cabinet outside switch block, and cabinet can be preferable
Protection operator personal safety, and cabinet can play a supporting role to switch block, and driving assembly uses umbrella tooth
Wheel drive structure, the driving assembly of structure design has the characteristics that stable transmission is reliable, operation is convenient, so that the box-type connects
Ground switch has the advantages that structure is simple, stable and reliable for performance, operation is convenient, small in size, compact-sized.
Particularly, the cabinet includes the first support plate, the second support plate, third support plate, the 4th support plate, described
The first support plate, the second support plate, third support plate, the 4th support plate be sequentially connected and constitute the cabinet in box shape,
The both ends of the main shaft are rotatably connected on the second support plate, in the 4th support plate respectively.The body structure letter of structure design
Single, cabinet can play a supporting role to main shaft, and switch block is arranged in cabinet, and cabinet can preferably protect operator
Personal safety.
Detailed description of the invention
Fig. 1 is the utility model embodiment perspective view.
Fig. 2 is the utility model embodiment main view.
Fig. 3 is the A-A cross-sectional view of Fig. 2.
Specific embodiment
As shown in Figures 1 to 3, the utility model embodiment is a kind of box-type earthing switch, including cabinet 10, setting in case
Switch block 20 in body 10, the driving for being arranged on cabinet 10 and executing separating brake or feed motion for driving switch component 20
Component 30, the switch block 20 include the main shaft 21 being rotatably arranged in cabinet 10, the plug-in strip with the linkage setting of main shaft 21
22, insulator, spring 23, the static contact of setting on the insulator, the driving assembly 30 include being arranged at corresponding main shaft 21
On cabinet 10 gear shaft 31, be arranged on main shaft 21 drive bevel gear 32, be arranged on gear shaft 31 and with transmission umbrella
The driving bevel gear 33 that gear 32 is meshed has the rocking handle jack 311 extended in outside cabinet 10 on the gear shaft 31,
The drive bevel gear 32 is with the movement of driving bevel gear 33 and main shaft 21 can be driven to rotate.As illustrated in fig. 1 and 2, the case
Body 10 includes the first support plate 11, the second support plate 12, third support plate 13, the 4th support plate 14, first support plate
11, the second support plate 12, third support plate 13, the 4th support plate 14 are sequentially connected and constitute the cabinet 10 in box shape, institute
The both ends for the main shaft 21 stated are rotatably connected on the second support plate 12, in the 4th support plate 14 respectively.The cabinet knot of structure design
Structure is simple, and cabinet can play a supporting role to main shaft, and switch block is arranged in cabinet, and cabinet can preferably protect operation
The personal safety of personnel.
The earthing switch is provided with cabinet outside switch block, and cabinet can preferably protect the person peace of operator
Entirely, and cabinet can play a supporting role to switch block, and driving assembly uses bevel gear driving structure, structure design
Driving assembly has the characteristics that stable transmission is reliable, operation is convenient, so that the box-type earthing switch has, structure is simple, performance
Advantage reliable and stable, operation is convenient, small in size, compact-sized.
