Abstract

The utility model relates to the technical field of daily necessaries, in particular to a curtain rolling structure which can be rolled up and down, which comprises a bracket, curtain and a rope for pulling up and down. The upper end of the curtain is arranged fixedly on the bracket; the pulling end of the rope for pulling up and down is passed through a slip resistance mechanism fixed on the bracket; the other end is arranged across to the other end of the curtain from the lower end of the curtain and is connected with a conical body whose small end is embedded into a via hole of a button arranged fixedly on the bracket, and whose big end is locked at the end of the via hole; an open slot communicated with the via hole is arranged on the button along the side edge of the via hole. The positioning end of the rope for pulling up and down is connected with the conical body; the rope for pulling up and down is positioned through the conical body and the button being matched. When the external force over 3 kg is acted on the rope for pulling up and down, the conical body can be expanded through the open slot on the button and is unbuttoned. The utility model is in simple structure and good safety.

Description

A kind of roller shutter structure

Technical field:

The utility model relates to the daily living article technical field, refers in particular to a kind of roller shutter structure of rolling up and down.

Background technology:

Curtain is as a kind of daily living article, because it has light intensity in the conditioning chamber, beautifies many functions such as indoor environment, is widely used in places such as family, school and office at present.Especially up and down the roller shutter of rolling is subjected to people's favor especially deeply.The roller shutter of rolling is to realize the superimposed or sagging expansion of rolling of curtain by striding the operating thread folding and unfolding of being located at the curtain both sides up and down, when using, reality only need spur the stretching end of operating thread, so that the contraction in length of the part operating thread of double team curtain makes curtain by the lower end purpose of rolling upwards automatically.But its operating thread of roller shutter that current people use has an end to be fixedly connected on the support, and the other end extends the outer user's operation of being convenient to after being arranged in limited-slip mechanism.Because operating thread is arranged at the both sides of curtain and is hanging type, like this no matter curtain is rolling or lowering, it is one sleeved that the part operating thread that connects curtain all becomes, and cover is buckled in the people sometimes, especially then can cause insight accident in advance during the hitch child, lack safety guarantee.

Summary of the invention:

The purpose of this utility model is to provide a kind of operating thread to be subjected to certain external force to do the time spent can throw off the better roller shutter structure of security automatically.

The utility model is achieved by the following technical solution: the stretching end of operating thread is arranged in a limited-slip mechanism that is installed on the support, its other end is established opposite side to curtain by the following end span of curtain, and connect a bullet, the small end of this bullet embeds and is installed in the through hole of the button on the support, and the big end of bullet is stuck in the end of through hole, simultaneously on the button, offer the open slot that is communicated with through hole along the through hole lateral margin, this open slot is positioned at the positive front side of through hole, and vertically setting.

The big end surfaces of described bullet is a spherical cambered surface, and the small end of bullet to be provided be to receive to put the connecting hole of backguy; Described button is a plastic rubber shaping body, and the end of the big end of clamping bullet of through hole is an inner concavity.

Its positioning end of operating thread of the present utility model is connected with bullet, cooperates the location operating thread with button by bullet, and when certain external force acted on operating thread, bullet can be triped by safety on the button again simultaneously, and it is simple in structure, and security is good.

Accompanying drawing 1 is a structural representation of the present utility model;

Accompanying drawing 2 is the button of the utility model and the schematic perspective view of bullet;

Accompanying drawing 3 is a user mode schematic diagram of the present utility model.

The specific embodiment:

See accompanying

drawing

1,2,3, the utility model includes support 1, curtain 2 and operating thread 3, curtain 2 upper ends are fixedly arranged on the support 1, the stretching end of operating thread 3 is arranged in a limited-slip mechanism that is installed on the support 1, the other end of operating thread 3 is established to the opposite side of curtain 2 by the following end span of curtain 2, and connects a bullet 4.The big end surfaces of bullet 4 is a spherical cambered surface, and the small end of bullet 4 to be provided be to receive to put the connecting hole 41 of backguy 3, the small end of bullet 4 embeds and is installed in the through hole 51 of the button 5 on the support 1, and bullet 4 big ends are stuck in the ends of through hole 51.Button 5 is a plastic rubber shaping body, and the ends of the clamping bullet of through hole 51 4 big ends are inner concavity, simultaneously on the button 5, through hole 51 positive front sides vertically offer the open slot 52 that is communicated with through hole 51 along the direction of through hole 51.

During use, the stretching end of pulling operating thread 3, so that be folded in the contraction in length of the part operating thread 3 of curtain 2 both sides, curtain 2 lower ends are upwards rolling automatically under the effect of operating thread 3, and curtain 2 rollings are got final product operating thread 3 lockings by limited-slip mechanism when arriving the appropriate location again.When operating thread 3 cover that is suspended on curtain 2 both sides fastens other object and is subjected to external active force and does the time spent, also corresponding stressed the forcing of bullet 4 that connects operating thread 3 one ends pressed the through hole 51 that struts button 5, and the through hole 51 of button 5 is by open slot 52 past both sides distendings, so that the big end of bullet 4 also can pass through hole 51 downslides and throw off holding of button 5, the respective end of operating thread 3 is also promptly thrown off the location, operating thread 3 ring sets are removed and relieving hitch object, avoid contingency to take place, especially avoided being taken place by the operating thread 3 outstanding danger that fasten because child plays.

The utility model is simple in structure, and is practical, also applicable to folding curtain about other, as sun blind, Roman shade etc.
