Abstract

The utility model relates to a waterproof socket bracket which comprises a bracket body (1), an annular bulge (2) arranged on the bracket body and a cylindrical sealing ring (3) arranged on the annular bulge (2), wherein the outer side of the bottom of the annular bulge (2) is provided with an annular groove (21) and a circle of small holes (22), and the bottom of the cylindrical sealing ring (3) is tightly sheathed on the annular bulge (2); the bracket body (1) is provided with through holes (11) on the periphery of the annular bulge (2). The utility model has the advantages that the annular bulge is provided with the broad cylindrical sealing ring which completely coats up the naked part of a power plug to stop outside dust and water drop invading; the cylindrical sealing ring is suitable for various plugs in slightly different sizes and is suitable for practical application. Simultaneously, via the design of the groove and the small holes on the bottom of the annular bulge and the through holes on the bracket body, the cylindrical sealing ring is firmly combined with the annular bulge and the bracket body so as to enhance bond strength and high durability.

Description

Water-tight Socket Stent

Technical field

The utility model relates to a kind of support of supply socket, relates in particular to a kind of support of waterproof socket.

Background technology

The kind of socket is a lot of at present, common socket, fixed socket, mobile socket, multipurpose socket etc. are arranged, but because of socket in practice, contact with water easily, bring potential safety hazard to the user, so some sockets with water-proof function are invented, be a kind of waterproof socket ZL03231540.6 (publication number is CN2627680Y) Chinese utility model patent " waterproof socket " discloses as the patent No..It is provided with the cylindrical shape projection at the spigot of waterproof socket, and is provided with annular groove in the opening part inboard of this cylindrical shape projection, is embedded with an O-ring seal in this annular groove, by the realization water-proof function that is sealed and matched of this O-ring seal and plug.The O-ring seal of She Zhiing like this, loosening easily through using for a long time, even come off, directly influenced waterproof effect; And the size of cylindrical shape projection must and the periphery of plug match, and cylindrical shape projection size can not change once fixing, so just can not be applicable to different big or small plugs, is unsuitable for very much actual use.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of waterproof effect better and be suitable for the Water-tight Socket Stent of actual use at above-mentioned prior art present situation.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: this Water-tight Socket Stent, include stake body and the annular protrusion that is provided with on it, and it is characterized in that described annular protrusion is provided with the cylindrical shape sealing ring.

The set-up mode of described cylindrical shape sealing ring on annular protrusion can adopt existing various technology, but it is more firm for what the cylindrical shape sealing ring was fixed, described annular protrusion bottom outside can be provided with an annular groove, described cylindrical shape sealing ring bottom just is set on the described annular protrusion tightly, and the part of described cylindrical shape sealing ring just is embedded in the annular groove of described annular protrusion bottom, thereby makes both firm being connected as a single entity.

For further strengthening the firm connection between described annular protrusion and the cylindrical shape sealing ring, can leave a circle aperture in the bottom of described annular protrusion, thereby the part of described cylindrical shape sealing ring bottom is imbedded in this aperture, and be embedded one with described annular protrusion, be fixed on firmly on the described stake body then.

Equally, for further strengthening the firm connection between described stake body and the cylindrical shape sealing ring, described stake body can have through hole in described annular protrusion periphery, thereby the part of cylindrical shape sealing ring bottom is penetrated in this through hole, and firmly is connected with described stake body.

Described cylindrical shape sealing ring can adopt general elastomeric material, so have certain dilatability, can be applicable to the plug that size is different slightly, but for making the cylindrical shape sealing ring all have the better waterproof energy for the plug of different sizes, the top of described cylindrical shape sealing ring can be provided with a circle inward flange, so just strengthened and being sealed and matched of various plugs, enlarged the scope of application.

Compared with prior art, advantage of the present utility model is: roomy cylindrical shape sealing ring is set on annular protrusion, the exposed part of attaching plug can be coated wherein fully, stopped the intrusion of extraneous dust and water droplet, waterproof effect is near ideal effect, and be applicable to the plug that all size is different slightly, be very suitable for practical application; Simultaneously, the design of through hole on annular protrusion bottom groove and aperture and the stake body makes the combination between cylindrical shape sealing ring and annular protrusion, cylindrical shape sealing ring and the stake body more firm, has improved bond strength, and durable in use; The utility model is simple in structure, and outward appearance is neat and artistic, is easy to apply.
