Scrapping for whole product will so be caused.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of guide sleeve that can effectively prevent that guide sleeve from reversing and fixed
Circle and the vacuum interrupter provided with the guide sleeve retainer plate.
In order to solve the above technical problems, the technical scheme that guide sleeve retainer plate of the present utility model provides is：Including circle body,
The upper open end of described circle body extends radially inwardly to be formed only turns round through hole for fixed guide set, and described through hole of only turning round is used
Reversed in preventing guide sleeve.
In one embodiment, the lower open end of described circle body extends radially outwardly to form installation connection side, passes through peace
Load edge fit can make circle body be connected with miscellaneous part realization.
In another embodiment, described through hole of only turning round includes at least one only torsion inwall, can be prevented by only turning round inwall
Guide sleeve reverses.
Implement structure as a kind of of inwall is only turned round, described only turns round inwall generally linear wall.
Implement structure as the another of torsion inwall is stopped, described only torsion inwall is relative through hole radial direction of only turning round into circle body
Recessed or evagination arcwall.
As the another implementation structure for only turning round inwall, described inwall of only turning round is continuous waveform wall, continuous teeth wall.
Further, described through hole of only turning round includes six linear walls, and six linear walls connect to form hexagon only torsion
Through hole.
Further, it is that regular hexagon only turns round through hole that described hexagon, which only turns round through hole,.
In another embodiment, the bottom of described ring-type lamellar body structure sets radial direction convex tendon, described radial direction convex tendon edge
The bottom of ring-type lamellar body structure is in be circumferentially arranged.
Guide sleeve retainer plate of the present utility model, through hole is only turned round because being provided with, and through hole is only turned round by this can effectively prevent to lead
Rotated to set with moving conductive rod, it is therefore prevented that product is scrapped.
The utility model also provides a kind of vacuum interrupter, and the vacuum interrupter includes guide sleeve, above-mentioned guide sleeve is fixed
Circle, described guide sleeve are provided with fixed part, and described fixed part is provided with shape, the size of only turning round through hole with guide sleeve retainer plate
Mutually equipped only torsion outer wall.
Carried out between the guide sleeve and retainer plate of vacuum interrupter using the structure for only turning round through hole with only torsion outer wall is mutually equipped with
Only turn round, only torsion effect is good, ensure that the qualification rate of product.

Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
As illustrated, guide sleeve retainer plate of the present utility model, including circle body 1, the upper open end of described circle body 1 is radially
Extend inwardly to form and only turn round through hole 3 for fixed guide set 20, described through hole 3 of only turning round is used to prevent guide sleeve 20 from reversing.
In one embodiment：The lower open end of described circle body 1 extends radially outwardly to form installation connection side 4；It is described
Installation connection side 4 be continuous ring-type lamellar body structure, the bottom setting radial direction convex tendon 4.1 of the ring-type lamellar body structure is described
Bottom of the radial direction convex tendon 4.1 along ring-type lamellar body structure is in be circumferentially arranged.
Guide sleeve retainer plate of the present utility model, described through hole 3 of only turning round include at least one only torsion inwall 3.1.
Structure is realized as only torsion inwall 3.1：Described inwall 3.1 of only turning round can generally linear wall；Described stops
It can also be relative only torsion arcwall of the radial direction of through hole 3 to the concave or convex of circle body 1 to turn round inwall 3.1；Described only turns round inwall 3.1
Can also be continuous waveform wall, continuous teeth wall.
In a specific embodiment, described through hole of only turning round includes six linear walls, six linear wall connection shapes
Through hole is only turned round into hexagon.Stop the structure that is preferable to carry out for turning round through hole as hexagon, it is positive six that described hexagon, which only turns round through hole,
