Abstract
The utility model discloses a dust-proof cover used for a wall bushing. The cover comprises an annular installation disk. An outer edge of the installation disk is provided with a support retaining ring. A dustproof and waterproof telescopic sleeve which is extended towards two sides is fixedly arranged out of the support retaining ring. An end surface of one side of the dustproof and waterproof telescopic sleeve is provided with an antiskid protruded line. An inner ring of the antiskid protruded line is provided with a sticky layer used for gumming. The structure of the dust-proof cover of the utility model is simple and reasonable. Installation and usage are convenient. During usage, an insulation sleeve tail end is installed on the wall bushing along an inner ring of the installation disk so that dustproof and waterproof performance of the wall bushing can be effectively increased. A problem of poor contact of high voltage wiring can be avoided, wherein the problem is caused by the wall bushing which is influenced by dust and rainwater. Line security is effectively guaranteed.
Description
Technical field
The utility model relates to electric fittings field, is specially a kind of wall bushing dirt-proof boot.
Background technology
Wall bushing is that high voltage source is passed through to wall, by indoor guide into outdoor or by indoor guide into indoor, also or inside and outside high-voltage switch gear or transformer, pass through the device that shell wall carries out high voltage source guiding.And existing wall bushing structure is reasonable not, it is convenient not to install, and after installing, stretches out that the outdoor section of body of wall is dustproof, water-resistant performance is not good, after long-time use, easily falls into more dust or affected by rain erosion, and then easily cause high-voltage connection loose contact, affect line security.
Utility model content
The purpose of this utility model is to provide a kind of wall bushing dirt-proof boot, the outdoor section that stretches out body of wall to solve after wall bushing traditional in prior art is installed prevents dust, water-resistant performance is not good, after long-time use, easily fall into more dust or affected by rain erosion, and then easily cause high-voltage connection loose contact, affect the problem of line security.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of wall bushing dirt-proof boot, it is characterized in that: include annular mounting disc, described mounting disc outer rim is provided with backup washer, dustproof, the rainproof telescopic that extend in the oriented both sides of the outer fixed installation of described backup washer, described end face dustproof, rainproof telescopic one side is provided with anti-skidding burr, and described anti-skidding burr inner ring is provided with the sticky glutinous layer of using with gluing.
Described a kind of wall bushing dirt-proof boot, is characterized in that: described mounting disc inner ring is provided with internal thread.
The beneficial effects of the utility model are:
The utility model is simple and reasonable, easy to install, during use, the insulating case tail end of wall bushing will be arranged on along mounting disc inner ring, can effectively improve dustproof, the water-resistant performance of wall bushing, prevent that wall bushing is subject to dust and rainwater affect and cause high-voltage connection to occur the problem of loose contact effectively having guaranteed the fail safe of circuit.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
