Abstract

The utility model relates to a fully sun-shading shutter which comprises an upper beam, a rotating shaft assembly, a hanging rope, a pulling rope and blades, wherein the rotating shaft assembly is penetrated through the upper beam and is provided with a controller, and a control lever arranged on the controller extends from the lateral side of the upper beam to control the rotation of the rotating shaft assembly; one end of the hanging rope is penetrated through the rotating shaft assembly and extends from the bottom of the upper beam, and the end of the hanging rope is fixedly connected with a plate block. Loop-shaped elements are arranged on the hanging rope at positioning intervals, and the loop-shaped elements are sheathed in fasteners which are below the blades. The blades are positioned below the upper beam at equal intervals. The hanging rope and the pulling rope are penetrated through both sides of each of the blades, so that the interval between the hanging rope and the pulling rope becomes quite small to guarantee the sealing performance among the blades, and the utility model can have good sun-shading performance.

Description

The shutter of complete shading

The utility model relates to shutter, relates in particular to a kind of shutter of complete shading.

Consult Fig. 1, shown in Figure 2, the tradition shutter comprises, one puts the beams in place 1, one rotating shaft 2, two stay cords 3, number blade 4, four lifting ropes 5 and number connect ran 6, wherein, rotating shaft 2 is located in the upper beam 1, stay cord 3 one ends hang down and are located at 1 bottom of putting the beams in place, it is terminal affixed with a plate 3a, after the other end of stay cord 3 passes 1 inside of putting the beams in place, passed by 1 side of putting the beams in place, blade 4 generally is circular-arc to upper process, and central authorities are provided with the perforation 4a of suitable length again, this perforation 4a can pass for stay cord 3, lifting rope 5 is located at the both sides of blade 4 respectively, and the top is fixed in the rotating shaft 2, and the bottom of every blade 4 is provided with a connection ran 6 and is connected on two lifting ropes 5, and utilize lifting rope 5 and be connected ran 6 cooperations, can make blade 4 reach the location purpose.

The shutter of this structure, can reach blade 4 folds, adjust the purpose of angle, when blade 4 adjustment are approximate vertical and reach shaded effect (shown in Figure 2), because perforation 4a is arranged on the middle position of blade 4, the 4 times ora terminalis of blade that are positioned at the top there is no the method 4a that will bore a hole and cover fully, cause light still can penetrate indoor by perforation 4a, so can't reach preferable shaded effect, again because perforation 4a is located at blade 4 central authorities, make that the distance of 5 of stay cord 3 and lifting ropes is bigger, and can't make the root edge of top blade 4 be close on the prominent face 4b of lower leaflet, light is infiltrated, in addition, when the concave surface 4c that is radiated at blade 4 when outdoor light goes up, concave surface 4c can refract on the prominent face 4b of lower leaflet 4, and prominent face 4b can import light indoorly again, makes shaded effect not good.

The purpose of this utility model is to provide a kind of shutter of complete shading, and the appropriate design that it utilizes stay cord and lifting rope is when being similar to vertical blade, and interlobate adaptation is good, to reach preferable shaded effect.

The purpose of this utility model is realized by following technical scheme.

The shutter of the complete shading of the utility model, comprise: a upper beam, a rotating shaft assembly, two lifting ropes, two stay cords and number blade, described rotating shaft assembly is located in the upper beam, and on rotating shaft assembly, be arranged with controller, be provided with control lever on this controller, this control lever stretches out from the upper beam side, rotate with the control rotating shaft assembly, its improvements are, described lifting rope one end wears respectively and is fixed on the rotating shaft assembly, and stretch out from the bottom of putting the beams in place, it is terminal affixed with plate, and each location spacing of this lifting rope is provided with a cast element; Described stay cord one end hangs down and is located at the bottom of putting the beams in place, and penetrates respectively in the cast element, and it is terminal affixed with plate; It also includes several fasteners, and described fastener is earlier each cast element to be inserted in wherein, fastener is placed several blades below again, and is fastened, and utilizes combining of cast element and fastener, several blades are uniformly-spaced be positioned at put the beams in place below.

Structure of the present utility model, can make the suitable distance of formation between blade, penetrate indoor for outdoor light, when the operation control lever rotates, the driving rotating shaft is rotated, the lifting rope that is positioned at the blade outside is pulled upwardly, the lifting rope that is positioned at the blade inboard is loosened and a little to bottom offset, till the top blade touches lower leaflet, blade is when being similar to vertical, because the top blade is close on the lower leaflet, make interlobate adaptation preferable, so when outdoor light was radiated on the blade, light leakproof part really had preferable shaded effect.

Concrete structure of the present utility model is provided in detail by following examples and accompanying drawing thereof.

Consult Fig. 4 to shown in Figure 7, the shutter of the complete shading of the utility model, comprise: a upper beam 10, rotating shaft assembly 20, two lifting ropes 30, two stay cords 40, number blade 50, described rotating shaft assembly 20 (commonly use structure, do not repeat them here) is located in the upper beam 10, and is arranged with a controller 11 on rotating shaft assembly 20, be provided with a control lever 12 on this controller 11, this control lever 12 stretches out from 10 sides of putting the beams in place, and rotates with control rotating shaft assembly 20, thereby reaches the purpose of adjusting blade angle.

Two lifting ropes, 30 1 ends are worn respectively and are fixed on the rotating shaft assembly 20, and stretch out from 10 bottoms of putting the beams in place, its end places the bottom of plate 60, and affixed with it, and in addition, each location spacing of lifting rope 30 is provided with a cast element 31; Described stay cord 40 1 ends hang down and are located at 10 bottoms of putting the beams in place, and penetrate respectively in the cast element 31, and its end penetrates plate 60 sides and affixed with it.

Each graphic elements 31 is inserted in the fastener 51, again fastener 51 is placed several blades 50 belows, and be fastened, utilize combining of cast element 31 and fastener 51, blade 50 is uniformly-spaced is positioned at 10 belows of putting the beams in place.

Structure by above-mentioned member composition, can make 50 in blade form suitable distance, so can penetrate indoor for outdoor light, otherwise, when operation control lever 12 rotates, can drive rotating shaft and rotate, when rotating shaft is rotated, the lifting rope that is positioned at blade 50 outsides can be pulled upwardly, and the lifting rope that is positioned at the blade inboard then can be loosened and a little to bottom offset, till the top blade touches lower leaflet; Like this, because lifting rope and stay cord all design the both sides at blade, make blade be operated and be when being similar to vertical, distance between lifting rope and stay cord is quite little, can guarantee interlobate adaptation, so when outdoor light is radiated on the blade, because the top blade is close on the lower leaflet, light leakproof part really has preferable shaded effect.

In sum, the shutter of the complete shading of the utility model, overall construction design science, rationally, easy to use, the shaded effect ideal overcomes the defective of traditional product, reaches design purpose.
