Abstract
The utility model discloses a conductive rotating shaft protective structure of an outdoor isolation switch. The protective structure comprises a rotating shaft base, a conductive rotating shaft and a protective cover. The center part of the rotating shaft base is vertically provided with an installation hole. The conductive rotating shaft is vertically disposed in the installation hole. The lower side of the rotating shaft base is provided with an installation groove. The transverse size of the installation groove is greater than the transverse size of the installation hole. The center line of the installation groove shares the same line as the installation hole. The protective cover is disposed inside the installation groove. The protective cover is provided with a hole used for allowing the conductive rotating shaft to pass through. The protective structure is provided with the installation groove used for installing the protective cover at the lower side of the rotating shaft base, so as to allow the protective cover to be installed in the installation groove. The protective cover can protect the conductive rotating shaft and prevent the conductive rotating shaft from being eroded by dust, sand storm, rain and snow to influence conductive performance.
Description
Technical field
The utility model relates to a kind of switch, is specifically related to a kind of conduction rotating shaft safeguard structure of outdoor disconnector.
Background technology
Existing outdoor disconnector contact shaft seat comprises shaft seat body, vertically offers the installing hole for conduction rotating shaft is installed at the middle part of shaft seat body, and conduction rotating shaft is arranged in installing hole.Because this installing hole is through hole, after conduction rotating shaft is arranged in installing hole, its top and bottom all contact with the external world, are easily subject to pollution, the erosion of dust in air, dust storm and sleet, thereby cause conducting electricity the electric conductivity reduction of rotating shaft, shortening in useful life.
Summary of the invention
For above-mentioned deficiency of the prior art, the utility model provides a kind of and can prevent dust, the conduction rotating shaft safeguard structure of the outdoor disconnector of sand-proof, rain and snow.
To achieve these goals, the technical solution adopted in the utility model is as follows:
A kind of conduction rotating shaft safeguard structure of outdoor disconnector, comprise shaft seat, conduction rotating shaft and protective cover, middle part at shaft seat vertically offers installing hole, conduction rotating shaft is vertically arranged in installing hole, downside at shaft seat offers mounting groove, the center line that the lateral dimension of this mounting groove is greater than the lateral dimension of installing hole and the center line of mounting groove and installing hole is located along the same line, and described protective cover is arranged in mounting groove, offers the hole of passing for conduction rotating shaft on this protective cover.
Further, the cross sectional shape of described protective cover is U-shaped, offers the hole of passing for conduction rotating shaft in the bottom of U-shaped protective cover.
With respect to prior art, the utlity model has following beneficial effect:
The utility model is by offering the mounting groove for protective cover is installed at the downside of shaft seat, protective cover is arranged in mounting groove, this protective cover can play protective action to conduction rotating shaft, and the rotating shaft of avoiding conducting electricity is subject to the erosion of dust, dust storm, sleet etc. and affects electric conductivity.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Referring to Fig. 1: the conduction rotating shaft safeguard structure of outdoor disconnector, comprise shaft seat 1, conduction rotating shaft 2 and protective cover 4, vertically offer installing hole at the middle part of shaft seat 1, this installing hole is through hole, conduction rotating shaft 2 is vertically arranged in installing hole.Offer mounting groove 3 at the downside of shaft seat 1, the cross sectional shape of this mounting groove 3 can be circular, also can be rectangle, the lateral dimension of mounting groove 3 is greater than the lateral dimension of installing hole and the center line of mounting groove 3 and the center line of installing hole and is located along the same line, it is the lower end that mounting groove 3 is arranged on installing hole, the lateral dimension of mounting groove 3 is greater than the lateral dimension of installing hole, makes to form between mounting groove 3 and installing hole a step.The cross section of protective cover 4 is the shape matching with mounting groove, and protective cover 4 is arranged in mounting groove, offers the hole of passing for conduction rotating shaft 2 on protective cover 4.
In the present embodiment, the cross section of mounting groove 3 is circular, the cross section of protective cover is the circle matching with mounting groove, the longitudinal section of protective cover 4 is U-shaped, offer the hole of passing for conduction rotating shaft 2 in the bottom of U-shaped protective cover 4, U-shaped protective cover 4 is arranged in mounting groove 3 after being inverted, and conduction rotating shaft 2 is arranged in installing hole and through U-shaped protective cover 4.
Finally it should be noted that, above embodiment is only in order to the technical solution of the utility model to be described but not restriction technologies scheme, although applicant has been described in detail the present invention with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, those are modified or are equal to replacement technical scheme of the present invention, and do not depart from aim and the scope of the technical program, all should be encompassed in the middle of claim scope of the present invention.
