Description

Mullion section bar for external sunshade linkage double-roller shutter window

Technical Field

The utility model relates to an outer sunshade is spare part for roll up curtain window especially relates to an outer sunshade linkage is club's section bar for two roll up curtain windows.

Background

Along with the increasing demand of people on building energy conservation, building sunshade receives more and more attention. The traditional sun-shading mode adopts modes such as a large house cornice, a glass film, a curtain, an electric roller shutter window and the like to carry out sun-shading treatment. Electric roller shutter window generally drives single curtain piece for the motor on the market at present, the motor is located one side of rolling up the curtain axle, this end support intensity is high, rolling up curtain axle non-deformable, and the rolling up curtain axle other end does not have inside to support, very easy bending deformation, especially, the curtain piece of broad needs longer rolling up the curtain axle, this longer rolling up curtain axle bending deformation more easily, lead to the curtain piece to the one end slope that does not have the motor, longer rolling up the curtain axle then middle one end bending deformation that does not have the motor is more severe, lead to the curtain piece transferring and withdraw in-process both sides and be difficult for keeping balance, it is high to roll up curtain one end, one end is low, perhaps middle one end slack partially. Because the upper end surfaces of the left and right guide rails are straight edges, the diameter of the octagonal tube rolling curtain shaft is large, and the gap between the left and right guide rails is large, and the curtain sheet needs to be bent from the left and right guide rails to the octagonal tube rolling curtain shaft, therefore, when the curtain sheet moves, the curtain sheet coming out from the right-angle sides of the left and right guide rails is rolled up and put down by the rolling curtain shaft, the curtain sheet is easily contacted with the right-angle sides of the left and right guide rails and the rolling curtain shaft at the position to generate abrasion, the larger the deformation of the rolling curtain shaft is, the larger the contact force is, the larger the abrasion degree is, the damage of the curtain sheet is caused, the larger the gap is, the curtain sheet at the position is easy to damage due to no support. And the inner part of the roller shutter shaft is broken when the bending deformation time is long. The above reasons all make the service life of the electric roller shutter window greatly reduced, and especially the electric roller shutter window with wider curtain sheets has shorter service life, therefore, people are researching an electric roller shutter window with double curtain sheets which can be opened and closed simultaneously aiming at the wider curtain sheets, and the common solution is to use two motors which run synchronously to drive, the installation structure is complex, the installation gap is large, the sealing effect is poor, the maintenance difficulty is large, the control system of the motor is complex, the window sashes are still too small, and the two motors can cause the waste of equipment and the increase of cost when being installed. Therefore, it is necessary to research an external sunshade roller shutter window in which the roller shutter shaft is not easy to bend and deform, the breakage is very rare, and one motor which is not easy to damage the curtain sheets drives two curtain sheets to open and close simultaneously.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the above-mentioned problem that exists among the prior art, provide a club's section bar is used to two roller shutter windows of outer sunshade linkage, this club's section bar uses with the cooperation of the one of two bearing frames of the two roller shutter windows of outer sunshade linkage, can make a motor drive two curtain pieces open simultaneously and the difficult bending deformation of the roll curtain axle of the outer sunshade roller shutter window of closing, and the fracture condition takes place very little, and the curtain piece is not fragile.

In order to achieve the above object, the technical solution of the present invention is: a mullion section bar for an external sunshade linkage double-roller shutter window comprises a middle support closed cavity and left and right slide rail open cavities; the tail ends of the front inner wall and the rear inner wall of the left sliding rail open cavity and the right sliding rail open cavity are respectively provided with a rubber strip groove, and wool tops are arranged in the rubber strip grooves; the width and the thickness of the middle support closed cavity are ensured to be tightly matched with the front and the rear inserting plates of the one-driving-two bearing seats of the outer sunshade linkage double-roller shutter window.

Further preferably, the front and rear inner walls of the mullion section supporting the closed cavity are respectively provided with a reinforcing rib in a protruding manner. The supporting strength for supporting the closed cavity is enhanced.

The utility model discloses use with the cooperation of one of two bearing frames of two roller shutter windows of outer sunshade linkage, support the intermediate position of roller shutter shaft, can make the roller shutter shaft of the outer sunshade roller shutter window that a motor drove two curtain pieces be the indeformable deflection, the fracture condition takes place very little, the curtain piece is not fragile. Just the utility model discloses the installation is simple, and is with low costs.

Drawings

Fig. 1 is a schematic cross-sectional view of the present invention;

fig. 2 is a schematic view of a three-dimensional structure between a middle one-driving-two bearing seat, a left guide member and a middle stile section bar of the present invention.

Detailed Description

The invention is further described with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1 and 2, the stile section bar 10 of the present embodiment comprises a middle support closed cavity 3 and left and right slide

open cavities

2 and 4. The tail ends of the front inner wall and the rear inner wall of the left sliding rail open cavity 2 and the right sliding rail open cavity 4 are respectively provided with an adhesive tape groove 1, and wool tops are arranged in the adhesive tape grooves 1. The width and the thickness of the middle supporting closed cavity 3 ensure that the front and the

rear inserting plates

9 and 8 of the one-driving-two bearing pedestal 6 of the outer sun-shading linked double-roller shutter window are tightly matched. Preferably, the front and rear inner walls of the support closed cavity 3 are respectively provided with a reinforcing rib 5. And 7, a left guide piece of the external sunshade linkage double-roller shutter window.

Naturally, the invention also relates to other embodiments, and those skilled in the art can make corresponding changes and modifications according to the invention without departing from the spirit and substance of the invention, and these corresponding changes and modifications should be considered as improvements in the equivalent technology, and fall within the scope of protection of the claims of the invention.
