Abstract
The utility model discloses a special tool for changing a retainer spring of a quincuncial contact. The special tool comprises two staggered stay bars, and the staggered parts of the two stay bars are hinged together through a hinge; one end of each stay bar is a hand-held end, and the other end of the stay bar is an operation end on which a needle-shaped support pillar is arranged; one ends, provided with the needle-shaped support pillars, of the two staggered stay bars are bent inwards, and the inwards bent ends, provided with the needle-shaped support pillars are symmetrically provided with arc-shaped grooves. The special tool for changing the retainer spring of the quincuncial contact can realize quickly changing the retainer spring of the quincuncial contact, the spring changing efficiency can be improved, and the special tool is convenient to operate and saves time and labour, so that the normal use of the equipment can not be influenced due to the fact that the point discharge is caused by damaging the contact.
Description
Technical field
This practicality newly belongs to power equipment applied technical field, and a kind of Mume flower contact holddown spring is changed specific purpose tool specifically.
Background technology
In power equipment, Mume flower contact is widely used, and current used Switch equipment is as GIS, and vacuum switch etc., adopt Mume flower contact as main conducting connecting part mostly in parts of conduction that they use.Mume flower contact is normally by contact finger piece, tension spring and be configured to.Equipment is under running environment, the tension spring of Mume flower contact all the time can the environment in intrinsic temperature rise in, running time is longer, naturally can there is plastic deformation in spring, spring tension is not enough, and thrust declines, finally cause dynamic and static contact face to reduce, contact resistance increases, and dynamic and static contact heating will occur when serious, burns to wait to have a strong impact on the equipment breakdown that power equipment safety moves.Therefore, make regular check on, change fingertip spring, link is absolutely necessary.
At present, adopt common screwdriver or screwdriver to change instrument as the tension spring of Mume flower contact, the existing weak point of replacing that adopts common dismounting to carry out tension spring is more:
Shortcoming one: easily damage contact.In using the process of common screwdriver or screwdriver sled lower spring, need to be by contact certainly as fulcrum, because tension spring contacts closely with contact finger piece, spring pressure is large, need to select suitable fulcrum can prize spring.Contact volume is relatively little, belongs to metallicity contact in assembling and dissembling process, and contact is easily scratched, and causes point discharge, thereby affects the normal use of equipment.
Shortcoming two: inefficiency.Adopt the method to change spring, efficiency is low, and complicated operation affects equipment electric power feeding time.
Develop in sum a kind of novel Mume flower contact holddown spring and change instrument, become the current problem that needs solution.
Summary of the invention
The technical problem that the utility model solves has been to provide a kind of Mume flower contact holddown spring and has changed specific purpose tool, this utility model can realize the quick-replaceable of Mume flower contact holddown spring, simple to operation, time saving and energy saving, and can not damage contact and cause point discharge, affect the normal use of equipment.
For solving the problems of the technologies described above, the utility model Mume flower contact holddown spring is changed specific purpose tool, it is characterized in that, comprise two struts that are crisscross arranged, the staggered position of described two struts is hinged by hinge, and one end of described two struts is handheld terminal, the other end is operating side, needle-like fastener is set on described operating side, and described two add one end that the wrong strut arranging is provided with needle-like fastener and curve inwardly, described in be provided with the aduncate one end of needle-like fastener and be arranged with arc groove.
The handheld terminal of described two struts is provided with the arc-shaped protrusions of being convenient to grasp.
The beneficial effects of the utility model are: the utility model Mume flower contact holddown spring is changed the quick-replaceable that specific purpose tool can be realized Mume flower contact holddown spring, spring is changed efficiency and is improved, simple to operation, time saving and energy saving, and can not damage contact and cause point discharge, affect the normal use of equipment.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Fig. 1 is structural representation of the present utility model;
Structural representation when Fig. 2 is dismounting and change tension spring;
In figure: 1-strut, 11-handheld terminal ,12-operating side, 2-needle-like fastener, 3-arc groove, 4-arc-shaped protrusions, 5-tension spring.
The specific embodiment
As shown in Figure 1, a kind of Mume flower contact holddown spring of the utility model is changed specific purpose tool, it comprises two struts that are crisscross arranged 1, the staggered position of described two struts 1 is hinged by hinge, one end of described two struts 1 is handheld terminal 11, and the other end is operating side 12, on described operating side 12, needle-like fastener 2 is set, one end that described two struts that are crisscross arranged 1 are provided with needle-like fastener 2 curves inwardly, described in curve inwardly to be provided with on strut one end of needle-like fastener 2 and be arranged with arc groove 3.
The handheld terminal 11 of described two struts 1 is provided with the arc-shaped protrusions 4 of being convenient to grasp, and described arc-shaped protrusions 4 can increase the frictional force between hand and strut 1, is convenient to tension spring 5 to strut and take off.
As shown in Figure 2, during use, with hand, catch the handheld terminal 11 of strut 1, by operation handheld terminal 11, carry out the needle-like fastener 2 arranging on control operation end 12, two needle-like fasteners 2 are all inserted in the tension spring 5 of Mume flower contact, then operate handheld terminal 11 tension spring 5 is strutted to both sides, softened tension spring 5 can put arc groove 3 under along strut 1, and the handheld terminal 11 that drags backward subsequently strut 1 takes off tension spring.
Except the technical characterictic described in above-mentioned description, be the known technology of those skilled in the art.
Claims (2)
1. a Mume flower contact holddown spring is changed specific purpose tool, it is characterized in that, comprise two struts that are crisscross arranged, the staggered position of described two struts is hinged by hinge, one end of described two struts is handheld terminal, and the other end is operating side, and needle-like fastener is set on described operating side, one end that described two struts that are crisscross arranged are provided with needle-like fastener curves inwardly, described in be provided with the aduncate one end of needle-like fastener and be arranged with arc groove.
