Abstract
The utility model discloses a kind of bus-bar earthing line, including the U-shaped static contact of side opening, hand-held bar and the movable contact spring being arranged in the middle of the U-shaped static contact of side opening, described U-shaped static contact bottom is provided with a groove, slew gear is provided with groove, the bottom face level of the movable contact spring underrun slew gear static contact U-shaped with side opening is fixedly installed.This utility model simple structure is by arranging a slew gear between the U-shaped middle movable contact spring of existing side opening and static contact, so that this device insertion bus-bar earthing line when dynamic and static slice can automatic impaction occlusion earth bus, be not in loosen, it is simple and reliable for structure, easy to operate, earthing effect is good, greatly reduces labor intensity using this bus-bar earthing line, improves work efficiency, and it is equally convenient and swift when removing, with larger use value.
Description
Technical field
This utility model is related to a kind of new bus-bar earthing line.
Background technology
As shown in figure 1, existing busbar grounding line, is fixed to busbar and earth lead movable contact spring using bolt arrangement：
During operation, then staff's hand-held bar 4 is inserted into busbar between the static contact on action bars and movable contact spring, then
Rotated by bolt, movable contact spring, busbar and static contact are fixedly installed；But, as 2 position of busbar is higher, fastening bolt 5 exists
Very long extension rod 6 need to be used when being embodied as, and passing through extension rod carries out rotation fixation, so operates very not square
Just, meanwhile, bolt it is permanent using also easily occurring loosening and position skew, cause busbar 2 and earth lead movable contact spring 1 to contact not
It is good, so that earthing effect declines, it is difficult to play the effect that earth lead ensures safety.
Utility model content
The purpose of this utility model is to provide a kind of bus-bar earthing line, and when making the use of earth bus, operation is easier,
Labor intensity is reduced, the security performance of earth bus is improved.
This utility model adopts following technical proposals：
A kind of bus-bar earthing line, including the U-shaped static contact of side opening, hand-held bar and it is arranged on U-shaped quiet of side opening
Movable contact spring in the middle of contact, described U-shaped static contact bottom are provided with a groove, and slew gear is provided with groove, described
The bottom face level of the movable contact spring underrun slew gear static contact U-shaped with side opening is fixedly installed.
Described slew gear includes first, second gear setting up and down and spring successively, and one end of the spring passes through
Second gear is fixedly installed with the bottom of first gear, and the other end of spring is fixedly installed with the bottom of groove, first tooth
Wheel lower end is provided with two extension ears for preventing first gear from departing from groove；It is circle-arc tooth in first gear, the coordinated with which
It is the chock of diagonal on two gears, and on the periphery wall of second gear, is provided with four protuberances, is provided with the inwall of groove
The limiting groove coordinated with four protuberances, the limiting groove are divided into four high grooves and four low grooves, four high grooves and four low grooves
It is arranged alternately.
Described movable contact spring movable contact spring has certain angle with U-shaped static contact bottom face.
This utility model simple structure is returned by one is arranged between the U-shaped middle movable contact spring of existing side opening and static contact
Rotation mechanism so that this device insertion bus-bar earthing line when dynamic and static slice can automatic impaction occlusion earth bus, be not in
Loosen, simple and reliable for structure, easy to operate, earthing effect is good, greatly reduces labor intensity using this bus-bar earthing line,
Work efficiency is improved, and it is equally convenient and swift when removing, with larger use value.
Description of the drawings
Fig. 1 is the structural representation of existing busbar grounding line；
Fig. 2 is structural representation of the present utility model
Fig. 3 is the structural representation of revolving structure described in the utility model.
Specific embodiment
As shown in Figure 2,3, a kind of U-shaped static contact 1 of bus-bar earthing line, including side opening, hand-held bar 4 and it is arranged on
Movable contact spring group in the middle of the U-shaped static contact 1 of side opening, described movable contact spring group are dynamic for the first movable contact spring 2 and second from top to bottom
Contact 3, described U-shaped 1 bottom of static contact are provided with a groove 8, and slew gear 7 is provided with groove 8, and described second is dynamic tactile
The bottom face level of 3 underrun slew gear 7 of the piece static contact 1 U-shaped with side opening is fixedly installed.
Described slew gear 7 includes the setting up and down 1st, second gear 17 and spring 9 successively, and the spring is passed through
The bottom that second gear 17 is taken turns with the first tooth 14 is fixedly installed, and the other end and the bottom of groove 8 of spring 9 are fixedly installed, described
14 lower end of first gear is provided with two extension ears 13 for preventing first gear 14 from departing from groove 8, is provided with and extension on groove 8
The locating slot 12 that ear 13 is fixed；It is circle-arc tooth 15 in first gear 14, is the chock of diagonal in the second gear 17 coordinated with which
Four protuberances 11 are provided with 16, and the periphery wall of second gear 17, are provided with the inwall of groove 8 and four protuberances 11
The limiting groove of cooperation, the limiting groove are divided into four high grooves 18 and four low grooves 10, and four high grooves 18 and four low grooves 10 replace
Arrange.Slew gear used in this utility model can make the distance between movable contact spring and static contact alternate, just multiple
Taking and installing for bus is closed, as long as the distance between movable contact spring and static contact alternate can be realized（Two travel points it
Between）I.e. in this utility model protection domain.
Described movable contact spring movable contact spring has certain angle with U-shaped static contact bottom face.One angle of setting makes
During use, busbar line is more easy to into therebetween, convenient to operate.This utility model adopts spring and revolving structure to replace bolt, nothing
Need to be operated using extension rod, only need upwards one push away can fixation movable contact spring box busbar, fastening effect is very good.End-of-job
Afterwards, only need one to push away and can open upwards again, it is very easy to use, while ensureing that contact is consolidated, greatly reducing manpower
Running cost.
