Abstract
The utility model discloses a universal grounding wire clamp which comprises a hollow insulated operating rod, a left clamp plate and a right clamp plate; the left clamp plate and the right clamp plate are connected together by a strong torsion spring; the top inside the left and right clamp plates forms an arc shape; the left clamp plate is internally provided with a left groove; the right clamp plate is internally provided with a right groove; a groove mouth of the left groove and a groove mouth of the right groove correspond to each other; the hollow insulated operating rod and the left clamp plate form an integral structure; the right clamp plate is connected with a pressing handle by the strong torsion spring and a high strength stay wire in the hollow insulated operating rod; a strip-shape opening is arranged on a cylinder wall at the lower end of the hollow insulated operating rod; and the pressing handle through the strip-shape opening moves up and down, and further through the high strength stay wire drives the right clamp plate to open or close. When the universal grounding wire clamp is used, the pressing handle is pressed, the high strength stay wire is tensioned, and the strong torsion spring is stressed, so that the right clamp plate is opened, the bus or the bus bar is clamped at the groove mouth of the left and right clamp plates; and the pressing handle is released, the left clamp plate and the right clamp plate are closed, the groove mouth of the left and right clamp plates is also closed, so that the bus or the bus bar is firmly clamped.
Description
Technical field:
The utility model relates to a kind of managing security tools and instruments that a kind of power industry is generally applied, and particularly relates to the general earthing clamp that a kind of applicable outdoor bus or busbar are used.
Background technology:
At present, the portable earthing wire clip that China electric power system is used, has according to the classification of joint form: the types such as single tongue formula, double tongue type, spiral press formula, hold flat, hedgehog hydnum formula.Wherein single tongue formula, double tongue type are mainly used in circuit or bus and have a power failure and use while doing safety measure; Spiral presses formula, hold flat, be mainly used in busbar has a power failure and uses while doing safety measure.Earthing wire clip exists the reason of various ways to be mainly, for meeting the needs of difform equipment in the time that safety measure is done in power failure.
Due to the difference of earthing wire clip form, in actual applications, the earthing clamp of hanging wire road and bus can not be applied in bus-bar earthing easily, same, and earthing clamp used when bus-bar earthing can not be conveniently used in the ground connection of circuit and bus.So just cause part earthing clamp deficiency and the remaining strange phenomenon of partial earthing wire clamp in actual production.As not enough in the earthing clamp of hanging earthing conductor bus, and the earthing clamp that extension busbar is used is not used, on the contrary there is same situation.If be equipped with the enough various forms of earthing clamps of quantity, need to increase the input of fund, cause when increasing cost and increased again maintenance, also caused the idle and waste of ample resources simultaneously.
Utility model content:
Technical problem to be solved in the utility model is: a kind of simple in structure, easy to operate, safe and reliable general earthing clamp is provided, can meet the requirement of hanging busbar, can meet again the requirement of hanging bus and wire, thereby reduce kind and the quantity of stock's earthing clamp, avoided the idle and waste of resource.
The technical scheme that the utility model is taked for technical solution problem is:
A kind of general earthing clamp, comprise hollow insulating bar and earthing clamp joint, described earthing clamp joint comprises left clamping plate and right clamping plate, between described left clamping plate and right clamping plate, link together by powerful torsion spring, be provided with bus in the center of described left clamping plate inside or busbar clamps left groove, be provided with bus in the center of described right clamping plate inside or busbar clamps right groove, the groove mouth of described left groove and right groove in correspondence with each other; Described hollow insulating bar and left clamping plate are integral type structure, the high strength bracing wire of described right clamping plate by powerful torsion spring and hollow insulating bar inside with press handle and be connected, in described hollow insulating bar, on the cylindrical wall of lower end, be provided with strip gab, described in press that handle moves up and down by strip gab and then drive right clamping plate to open or closed by high strength bracing wire; The top of described left clamping plate and right clamping plate inner side is circular shape.
The lower right corner place in described right clamping plate outside is provided with connection fastening bolt, and described earth connection is connected with right clamping plate by connecting fastening bolt.
The described handle of pressing is processed by insulating material.
When use, press the handle of pressing of the present utility model, high strength bracing wire tensioning, powerful torsion spring is stressed, and right clamping plate are opened, and bus or master clamp is held in to the notch place of left clamping plate and right clamping plate; Unclamp the handle of pressing of the present utility model, left clamping plate and right jaws close, the notch of left groove and right groove is also thereupon closed, so just bus or busbar is firmly clamped.
In the utility model, distribute because the top of left clamping plate and right clamping plate inner side is circular shape, make bus or busbar enter groove mouth more smooth, avoid the generation of hanging and pulling bus or busbar phenomenon.
The utility model is simple in structure, safe and reliable, easy to use, has solved the problem that the earthing clamp of prior art median generatrix or busbar can not be general, has good practical value and marketing prospect.
Brief description of the drawings:
Fig. 1 is structural representation of the present utility model.
Embodiment:
Below in conjunction with accompanying drawing, the utility model is further described:
Referring to Fig. 1, a kind of general earthing clamp, comprise hollow insulating bar and earthing clamp joint, earthing clamp joint comprises left clamping plate 1 and right clamping plate 2, between left clamping plate 1 and right clamping plate 2, link together by powerful torsion spring 5, be provided with bus in the center of left clamping plate 1 inside or busbar clamps left groove 3, be provided with bus or busbar clamps right groove 4 in the center of right clamping plate 2 inside, the groove mouth of left groove 3 and right groove 4 in correspondence with each other; Hollow insulating bar 7 and left clamping plate 1 are integral type structure, the high strength bracing wire 6 of right clamping plate 2 by powerful torsion spring 5 and hollow insulating bar 7 inside with press handle 8 and be connected, press handle 8 and processed by insulating material; In hollow insulating bar 7, on the cylindrical wall of lower end, be provided with strip gab 9, press that handle 8 moves up and down by strip gab 9 and then drive right clamping plate 2 to open or closed by high strength bracing wire 6; The top of left clamping plate 1 and right clamping plate 2 inner sides is circular shape 12; Be provided with at the lower right corner place in right clamping plate 2 outsides and connect fastening bolt 10, earth connection 11 is connected with right clamping plate 2 by connecting fastening bolt 10.
When use, press the handle 8 of pressing of the present utility model, high strength bracing wire tensioning, powerful torsion spring 5 is stressed, and right clamping plate 2 are opened, and bus or master clamp is held in to the notch place of left clamping plate 1 and right clamping plate 2; Unclamp the handle 5 of pressing of the present utility model, left clamping plate 1 and right clamping plate 2 closures, the notch of left groove 3 and right groove 4 is also thereupon closed, so just bus or busbar is firmly clamped.
