Abstract

The utility model discloses a curtain capable of keeping out wind and rain. The curtain comprises a fan, a first pulley, a second pulley, a sash weight, a check curtain, a curtain frame and a rope; the fan is arranged on the wall body above the window; the first pulley is fixedly arranged on the wall body above the fan; the second pulley is fixedly arranged on the wall body on the left or the right of the first pulley; the curtain frame is fixedly arranged at the periphery of the window; a groove is formed on the inner wall of the curtain frame; the upper end of the check curtain is fixed on the curtain frame, and the lower end of the check curtain is connected with a reel; after a rotating shaft of the fan is wound by the rope, one end of the rope is fixedly connected with the sash weight after overstriding the first and the second pulleys, and the other end of the rope is fixed at the top of the curtain frame on the back side of the check curtain or at the top of the check curtain after overstriding the front side of the check curtain; and the weight of the sash weight is greater than those of the reel and the check curtain. The curtain automatically falls down and rolls up with the magnitude of external wind power, thereby guaranteeing fresh indoor air and indoor cleaning; the curtain needs not to be artificially operated and is very convenient; and meanwhile, the energy source needs to be wasted, thereby achieving real energy conservation, and simple and novel structure.

Description

The curtain of keeping out wind and rain

Technical field

The utility model relates to a kind of curtain, refers to a kind of curtain of keeping out wind and rain especially.

Background technology

Curtain divides outdoor window curtain and indoor curtain, and general residenter house is most of to use indoor curtain, and the effect of this indoor curtain is nothing more than the shielded room UV light, thereby reaches the adjustability and the crypticity of indoor light.Outdoor window curtain divides manually and electronic two kinds, manual relative trouble some, must operate by the people, and electronic except laborsaving, convenient outside, also need manual operation, more prior is exactly consume electric power, does not meet the standard of the energy-saving and emission-reduction that country advocates.

The utility model content

The purpose of this utility model provides a kind of curtain of keeping out wind and rain of rolling automatically and falling under the effect of nature wind-force.

To achieve these goals, the utility model is by the following technical solutions:

A kind of curtain of keeping out wind and rain, it comprises: fan, first pulley, second pulley, sash weight, check apron, pelmet and rope, described fan is arranged on the body of wall of window top, described first pulley is installed on the body of wall of this fan top, described second pulley is installed on the body of wall on the left side of this first pulley or right side, described pelmet be installed in window around, the inwall of this pelmet is provided with groove, the upper end of described check apron is fixed on the pelmet, the lower end of described check apron connects a spool, the body portion of described rope enwinds the rotating shaft of fan, a pile warp first, second pulley and sash weight are connected, around to the another side of check apron and be fixed on the top of check apron, the weight of described sash weight is greater than the weight of described spool and described check apron through the one side of check apron in the other end.

Between described fan shaft and the body of wall bearing is set, this bearing inner race is contained in the rotating shaft, and this bearing also is fixed on the body of wall.

Ran between the rotating shaft of described first pulley and described fan should tilt to the rotor shaft direction of fan.

The beneficial effects of the utility model: the resulting curtain of keeping out wind and rain of the utility model, size according to extraneous wind-force falls automatically and rolls, guaranteed the pure and fresh and indoor cleaning of room air, do not need manual operation, very convenient, simultaneously do not need to waste energy, accomplished real energy-conservationly, it is simple in structure, novel

The specific embodiment

As shown in Figure 1 to Figure 3, a kind of curtain of keeping out wind and rain, it comprises: fan 1, first pulley 2, second pulley 3, sash weight 4, check apron 5, pelmet 6 and rope 7.Fan 1 is arranged on the body of wall of window A top, and under wind-force drove, fan 1 can only rotate towards a direction.First pulley 2 is installed on the body of wall of fan 1 top, second pulley 3 is installed on the body of wall on the left side of first pulley 1 or right side, pelmet 6 be installed in window around, the inwall of pelmet 6 is provided with groove, the upper end of check apron 5 is fixed on the pelmet 6, the lower end of check apron 5 connects a spool 51, the body portion of rope 7 enwinds the rotating shaft 12 of fan 1, one head pile warp first pulley 2, second pulley 3 are connected with sash weight 4, around to check apron 5 another sides and be fixed on the check apron top, the weight of sash weight 4 is greater than the weight of spool 51 and check apron 5 through the one side of check apron 5 in the other end.

First pulley 2 is installed on the body of wall of fan 1 top, promptly first pulley 2 be installed in fan 1 directly on the body of wall or on the upper left side or top-right body of wall parallel with fan shaft 12.

Around the back side to check apron, its termination is fixed on the pelmet rope through the front of check apron, on the check apron or on the body of wall, guarantee under the drive of rope in front check apron to be scrolled up around its spool.With the curtain rolling shaft is that stress point is carried out the curtain rolling shaft lifting.

Be equipped with groove on the inwall around the pelmet 6, the both ends of the spool 51 of check apron 5 are installed with in groove and along it moves.In order to prevent check apron when wind is big, blown afloat the effect that can not protect from the wind and rain.

First pulley 2 be fixed on electric fan 1 rotating shaft 12 directly over, first pulley 2 and second pulley, 3 horizontal intervals are arranged.Stress balance when guaranteeing that check apron is rolled and fallen is walked around the rope 7 of check apron 5, preferably through the central alignment of spool 51.

Between the rotating shaft 12 of fan 1 and the body of wall bearing 13 is set, bearing 13 inner rings are contained in the rotating shaft 12, and bearing 12 is installed on the body of wall.

When flabellum 11 drives spool 12 rotations under the effect of wind-force, twine rope for convenience, the ran between the rotating shaft 12 of first pulley 2 and fan 1 should tilt to rotating shaft 12 directions of fan 1.

When reaching certain progression, wind-force reaches when polluting indoor cleaning; electric fan is kinetic force with wind; blade is forward rotation under the drive of wind-force; blade drives the rotating shaft rotation; the rope pulling sash weight that the top is rolled in rotating shaft rises; under the action of gravity of check apron and spool, drive rope simultaneously and move downwards, make check apron whereabouts closing windows, the protection indoor cleaning.Less or becalm when ending when wind-force, because the weight of sash weight is slightly larger than the weight of check apron and spool, sash weight falls, rotating shaft is backward rotation under the drive of sash weight, ran between rotating shaft and the sash weight is elongated, rope is pulled up, and check apron is the rolled-up lifting in axle center with the spool, reaches ventilation and degree with fresh air in the holding chamber.

More than be preferred embodiment of the present utility model and design graphic; above-mentioned preferred embodiment and designing graphicly only illustrates; be not to be used to limit interest field of the present utility model; all with equalization technological means or be the interest field that contained of the application's claim and the implementer does not all break away from protection domain of the present utility model.
