Abstract

The utility model provides an automatic roller shutter, comprising a roller, a rebound mechanism and an open positioning mechanism which are arranged in the roller, and a fixing base which is rotatably and movably connected at both ends of the roller. The rebound mechanism is connected with the roller and the fixing base at one end of the roller. The open positioning mechanism is composed of a bearing head, a screw bolt and an embedding head, the embedding head is screwingly connected on the screw bolt which is connected with the fixing base at the other end of the roller, and the embedding head is connected with the roller. The automatic roller shutter is characterized in that a rotary table is provided on the fixing bases, and the rotary table is connected with the screw bolt in the bearing head. Compared with the prior art, the automatic roller shutter has the advantages that the end part of shutter cloths is unnecessary to be fixed after the shutter cloths are opened, the shutter cloths can be opened stably, and the opened range of the shutter cloths is adjustable.

Description

A kind of automatic curtain

Technical field:

The utility model relates to a kind of curtain.

Background technology:

Existing automatic curtain by reel, be arranged on resilience mechanism in the reel, rotate the holder that is actively socketed on the reel two ends and constitute, resilience mechanism links together with reel, holder respectively.During use, by holder automatic curtain is positioned on the window, be fixed on casement on the reel and twist on the reel, when needs are opened curtain, down curtain is pulled down from reel by the stay cord that is fixed on below the casement, because when curtain pulls down, reel makes resilience mechanism hold the kinetic energy that has stored up resilience, when needs are opened curtain also along with rotation, only need unclamp stay cord, reel is recovered to curtain on the reel in the effect turning down of resilience kinetic energy, and this kind automatic curtain exists when opening curtain and the curtain end of opening need be fixed on below the window by stay cord, like this, use very inconvenient, and very not attractive in appearance, after stay cord disconnects, because of the curtain end can not get the location, make casement get back on the reel and make automatic curtain ineffective at the effect last volume of screen resilience.In order to overcome above-mentioned shortcoming, after people design a kind of curtain again and open, by the roller shutter of opening the detent mechanism locking that is arranged in the reel, after curtain is opened fully, open detent mechanism reel is locked, it can not be turned round, need be with the curtain rollback to reel the time, only need backward rotation one lower mandrel member, make and open detent mechanism and unblank, reel will be recovered to curtain on the reel in the effect turning down of resilience mechanism of self.Though this kind roller shutter does not need stay cord to fix, but, before owing to dispatch from the factory, the length that curtain is opened or the length of rolling are fixing, general user can, not be not easy to regulate the length that curtain opens or the length of rolling yet, can only just can finish by producer or professional person, so just bring very big inconvenience to the user.

Summary of the invention:

The casement end need not be fixed after goal of the invention of the present utility model is to provide a kind of casement to open, casement can both stably be opened, and curtain is opened length adjustment automatic curtain easily.

The utility model is to realize like this, comprise reel, be arranged on the resilience mechanism in the reel and open detent mechanism, rotate the holder that is actively socketed on the reel two ends, resilience mechanism respectively with reel, reel wherein the holder of an end link together, opening detent mechanism is made of support head, screw rod, embedding head, the embedding head thread is connected on the screw rod, the holder of the screw rod and the reel other end links together, embedding head and reel link together, its special feature is to be provided with rotating disk on holder, the screw rod in rotating disk and the support head links together.When needing the adjusting curtain to open length, rotate rotating disk, screw rod is rotated, like this, the embedding head will move forward and backward with the rotation of screw rod, regulates the rotary number of turns of reel by the distance of regulating between itself and support head, finally reaches to regulate the length that curtain opens or the length of rolling.After adjusting finishes, rotating disk is fixed on the holder, like this, the length that curtain is opened just is fixed up.

For convenience people rotate and fixing rotating disk, on holder, be provided with disk, the disk side is provided with recess, dial rotation is actively socketed on the disk, rotating disk upper edge periphery evenly is provided with and recess, be provided with snap ring on the side of disk and rotating disk, the inboard of snap ring is provided with fixture block, and fixture block is embedded on the recess of disk and rotating disk.During use, take off snap ring, rotating disk can be rotated relative to disk, to regulate the length that curtain is opened, after adjusting finishes, load onto snap ring, because disk is fixed on the holder and can not rotates, like this, rotating disk can not rotate, thereby has made things convenient for people's use.

Here, people open, pack up curtain for convenience, the pelletron that is provided with the pearl wheel and matches with the pearl wheel on the support head of reel side.During use, by pelletron curtain is opened, when need regaining curtain, oppositely pullled pelletron, make and open detent mechanism and unblank, reel will be recovered to curtain on the reel in the effect turning down of resilience mechanism of self.

People use pelletron for convenience, are equipped with the pearl wheel on the support head of reel both sides, and the pearl wheel side is equipped with disk, and the disk side is provided with recess, and snap ring is provided with the pelletron block, and the pelletron block is positioned at pearl wheel top.Like this, people just can use pelletron in the reel both sides.

Here, snap ring is made of two snap ring assemblies, and an end of two snap ring assemblies couples together by being flexible coupling, and the other end is by being arranged at hook above both, linking and connect.Like this, by hook, button loading, unloading snap ring easily just.

Compared with the prior art the utility model has and the casement end need not be fixed after casement is opened, and casement can both stably be opened, and casement is opened the adjustable automatic curtain of amplitude.
