Description
Technical field
The utility model relates to high-voltage switch gear field, particularly a kind of back-moving spring of isolating switch.
Background technology
Isolating switch is in high-voltage switch electric appliance, to use maximum a kind of electrical equipment, and as its name suggests, isolating switch plays buffer action in circuit, be one of modal high-voltage switch gear, and deformation occurs spring under external force, removes after external force
,spring just can return to form, isolating switch utilizes this character of spring to reset, as shown in Figure of description 1, the structure of the back-moving spring of existing isolating switch is: comprise return spring body 1 ', link rod base 2 ', movable link rod 3 ', hosel 4 ', firm banking 5 ' and fixed lever 6 ', described movable link rod 3 ' is fixed on link rod base 2 ', described hosel 4 ' is fixed on firm banking 5 ', described fixed lever 6 ' is fixed on isolating switch conductive arm through holder 5 ', described movable link rod 3 ' can plug and be connected in hosel 4 ', described return spring body 1 ' is located between link rod base 2 ' and firm banking 5 ' by the relative motion telescopically of movable link rod 3 ' and hosel 4 ', but this design need to be used the link rod base of at least one and the holder of at least one, waste very much resource, and the dismounting of back-moving spring is cumbersome.
Utility model content
Therefore,, for above-mentioned problem, the utility model provides a kind of and practical and conveniently, simple in structure, readily removable easily unloads, the back-moving spring of the isolating switch of saving resource.
For realizing above-mentioned technical problem, the solution that the utility model is taked is: a kind of back-moving spring of isolating switch, comprise return spring body, also comprise spring guide, steady pin, return spring alignment pin, described return spring body is sheathed on spring guide, one end of described spring guide is provided with long lumbar hole, the other end is provided with circular hole, described steady pin is arranged on long lumbar hole, described return spring alignment pin can be located on spring guide through circular hole on plug ground, described return spring body changes telescopically by the mutual alignment of return spring alignment pin and steady pin and is located between steady pin and return spring alignment pin, described spring guide is provided with the driving rod drive that drives spring guide to rotate near return spring alignment pin one end.
Further improved: described driving rod drive comprises pivot pin, transmission crank arm and final drive shaft, one end of described transmission crank arm is articulated with spring guide one end near return spring alignment pin by pivot pin, the described transmission crank arm other end is connected on final drive shaft, described final drive shaft drives transmission crank arm, and transmission crank arm drives spring guide rotation that the mutual alignment of return spring alignment pin and steady pin is changed.
By adopting aforementioned techniques scheme, the beneficial effects of the utility model are: a kind of back-moving spring of isolating switch, return spring body leads by spring guide, drive spring guide to rotate the variation of the mutual alignment that makes return spring alignment pin and steady pin by driving rod drive, realize compression and discharge; Long lumbar hole in spring guide has met the rotational angle of spring guide, and partially restrained the range of movement of whole system, with original back-moving spring ratio, replace original link rod base with return spring alignment pin that can plug, and saved firm banking, saved in large quantities the resources of production, and structure is more reasonable, facilitate the dismounting of back-moving spring, be highly suitable on market production and application on a large scale.
Brief description of the drawings
Fig. 1 is the structural representation of the back-moving spring of isolating switch in prior art;
Fig. 2 is the schematic diagram of the utility model embodiment return spring body compression;
Fig. 3 is the schematic diagram that the utility model embodiment return spring body discharges.
Embodiment
Now with specific embodiment, the utility model is further illustrated by reference to the accompanying drawings.
With reference to figure 1, Fig. 2 and Fig. 3, a kind of back-moving spring of isolating switch, comprise return spring body 1, spring guide 2, steady pin 3, return spring alignment pin 4, pivot pin 5, transmission crank arm 6 and final drive shaft 7, described return spring body 1 is sheathed on spring guide 2, one end of described spring guide 2 is provided with long lumbar hole 21, the other end is provided with circular hole, described steady pin 3 passes long lumbar hole 21 for whole back-moving spring being fixed on to the conductive arm of isolating switch, described return spring alignment pin 4 can be located on spring guide 2 through circular hole on plug ground, one end of described transmission crank arm 6 is articulated with spring guide 2 one end near return spring alignment pin 4 by pivot pin 5, described transmission crank arm 6 other ends are connected on final drive shaft 7, described final drive shaft 7 drives transmission crank arm 6, transmission crank arm 6 drives spring guide 2 rotations that the mutual alignment of return spring alignment pin 4 and steady pin 3 is changed, thereby realize compression and the release of back-moving spring.
By adopting aforementioned techniques scheme, a kind of back-moving spring of isolating switch, return spring body leads by spring guide, drives spring guide to rotate the variation of the mutual alignment that makes return spring alignment pin and steady pin by driving rod drive, realizes compression and discharges; Long lumbar hole in spring guide has met the rotational angle of spring guide, and partially restrained the range of movement of whole system, with original back-moving spring ratio, replace original link rod base with return spring alignment pin that can plug, and saved firm banking, saved in large quantities the resources of production, and structure is more reasonable, facilitate the dismounting of back-moving spring, be highly suitable on market production and application on a large scale.
Although specifically show and introduced the utility model in conjunction with preferred embodiment; but not departing from the category of the present utility model that appended claims limits; can make a variety of changes the utility model in the form and details, be protection range of the present utility model.
