Abstract
The utility model relates to the technical field of curtains, in particular to an improved curtain capable of being retracted and released conveniently, which comprises an upper rail, a curtain body, a retracting-releasing mechanism, a transmission bar, a winding device and a pull rope, wherein the winding device is provided with a winding section and an actuator capable of driving the winding section to move axially. The actuator is a screw rod which is rotatably connected with a screw hole in the upper rail in matching mode, and the screw rod is driven by the retracting-releasing mechanism to advance and retreat. The actuator is coaxially formed with the winding section which has a conical degree, and the small end of the winding section is connected with the actuator. When the curtain is retracted, the pull rope is wound from the big end of the winding section to the small end of the winding section. Blocking plates are arranged at two ends of the winding section. A thread groove used for facilitating the wind of the pull rope is arranged on the winding section. Retracting points of the pull rope are maintained at the same vertical position, and the pull rope is distributed in a thread line of a winding shaft after being wound on the winding section, thereby avoiding twining of the pull rope. A conical portion of the winding shaft is capable of compensating the arm of force, thereby avoiding change of moment of force caused by change of elastic force of the retracting-releasing mechanism and facilitating rope retraction.
Description
Technical field
The utility model relates to the curtain technical field, specifically is meant a kind of modified curtain of being convenient to folding and unfolding.
Background technology
The Winder of known curtain comprises rail 2, curtain body 1, jack 5, drive link 6, Winder 4 and stay cord 3 shown in Fig. 1 to 2, wherein Winder 4 comprises the straight roll that is installed on the mount pad.Prior art is in the process of packing up curtain body 1, drive link 6 drives Winder 4 stay cord 3 is wound on the roll, the power that curtain body 1 acts on jack 5 increases gradually, because of the moment of jack 5 constant, cause the dynamics of rolling curtain body 1 not enough, even the phenomenon of a part of curtain body 1 downward landing occurs; And when launching curtain body 1, the power that the supreme rail 2 of the force of gravity of curtain body 1, curtain body 1 act on jack 5 reduces gradually, and the moment of jack 5 is constant, therefore causes curtain body 1 to launch the back and forms certain resilience.Thereby the inconvenience when causing folding and unfolding.Secondly, traditional straight roll makes stay cord 3 produce wrapping phenomena easily when take-up, and promptly the coil of new coiling constantly is superimposed upon on the coil of coiling, thereby makes Winder 4 encounter difficulties when folding and unfolding.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of modified curtain of being convenient to folding and unfolding is provided.
The utility model is achieved through the following technical solutions, and comprises rail, curtain body, jack, drive link, Winder and stay cord, and described Winder has the coiling section and can drive the axially movable dynamic equipment of coiling section.Described dynamic equipment is a screw rod, and this screw rod cooperates the screw seat of going up in the rail to spin, and screw rod drives advance and retreat by jack.Described dynamic equipment and coiling section coaxial configuration, and the drive link of connection jack passes the mesopore of dynamic equipment and coiling section successively.Coiling section has tapering, and small end links to each other with dynamic equipment, and when curtain was packed up, stay cord was wound to small end from the big end of coiling section; Two ends in the coiling section are provided with baffle plate.Described coiling section is provided with the thread groove that makes things convenient for stay cord to twine.
Advantage of the present utility model is: 1. the take-up of stay cord point remains on same upright position, and distributes along the helical of roll after the stay cord coiling, and therefore the roll of motion rolling stay cord better vertically prevents the generation of wrapping phenomena; 2. the tapering part of roll can compensate the arm of force, overcomes the moment that the force variation because of take-up mechanism takes place and changes, and is convenient to take-up.

Fig. 2 is the Winder schematic diagram of Fig. 1;
Fig. 3 is the utility model schematic diagram;
Fig. 4 is the Winder schematic diagram of Fig. 3.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described further, as shown in Figure 3 and Figure 4, the utility model comprises rail 2, curtain body 1, jack 5, drive link 6, Winder 4 and stay cord 3, and described Winder 4 has coiling section 432 and can drive coiling section 432 axially movable dynamic equipments 431.During take-up work, dynamic equipment 431 drives coiling section 432 and moves axially, and stay cord 3 is wrapped on the coiling section 432 in order, and the coiling marshalling is avoided chiasma interference between the coiling, to guarantee the normal use of curtain, uses lighter.And during setting-out work, dynamic equipment 431 drives coiling section 432 and oppositely moves, and the coupling unwrapping wire makes curtain sagging smooth and easy.
In Fig. 3 and present embodiment shown in Figure 4, dynamic equipment 431 is a screw rod, and this screw rod cooperates the screw seats of going up in the rail 2 41 to spin, and screw rod drives advance and retreat by jack 5.Described dynamic equipment 431 and coiling section 432 coaxial configuration, and the drive link 6 of connection jack 5 passes the mesopore of dynamic equipment 431 and coiling section 432 successively.Coiling section 432 has tapering, and small end links to each other with dynamic equipment 431, and when curtain body 1 was packed up, stay cord 3 was wound to small end from the big end of coiling sections 432; Two ends in coiling section 432 are provided with baffle plate 433.Described coiling section 432 is provided with the thread groove that makes things convenient for stay cord 3 to twine.
When launching curtain body 1, stay cord 3 together launches with curtain body 1, and Winder 4 is in the rotation unwrapping wire, and dynamic equipment 431 moves forward in the effect of threaded block 41, and the bearing 421 on the bearing support 42 had both been followed drive link 6 and together rotated, and again drive link 6 was played a supportive role.In the expansion process, the supreme rail 2 of the force of gravity of curtain body 1, the power that curtain body 1 acts on jack 5 reduces gradually, and the moment of jack 5 is constant, the big end compensating of therefore coiling section 432 arm of force, the power that makes jack 5 act on the stay cord 3 reduces, and curtain body 1 equates with the power that folding structure 5 acts on the stay cord, can not produce rebound phenomenon after curtain body 1 launches.
When drawing curtain body 1 in, Winder 4 is in the rotation take-up, dynamic equipment 431 moves under the effect of threaded block 41 backwards, stay cord 3 is along the helical flute coiling of coiling section 432, prevent that stack and winding from appearring in stay cord 3 when coiling, 433 on the baffle plate at coiling section 432 two ends can limit the take-up scope of stay cord 3, and it can not disturbed the mobile generation of dynamic equipment 431.In the wrapup procedure of curtain body 1, the gravity that acts on the Winder 4 increases, and the small end of coiling section 432 has reduced the coiling arm of force at this moment, and the moment that curtain body 1 is produced is consistent with the moment of jack 5, is convenient to the gathering of curtain body 1.
More than diagram only is preferred embodiment of the present utility model, be not to limit practical range of the present utility model, so every principle according to the utility model is done the equivalence variation or modified with this, all should be covered by in the protection domain of the present utility model, for example dynamic equipment 431 be arranged in parallel with coiling section 432; Dynamic equipment 431 is a worm and gear etc. with the drive mechanism of drive link 6.
