Abstract
The invention relates to an improved structure of a curtain roller. A reel comprises two parallel and symmetrical taking-up levers, a gap is reserved between the two taking-up levers, connecting covers are arranged at two ends of each taking-up lever, toothed structures are arranged on the connecting surfaces of the ends of the two taking-up levers and the connecting covers, toothed structures matched with the toothed structures of the ends of the taking-up levers are arranged on the inner surfaces of the connecting covers, and the side outer surfaces of the connecting covers are provided with toothed structures rotatably connected with manufacturing heads and manufacturing tails in a toothed manner.
Description
Technical field
The invention belongs to curtain field, be specifically related to a kind of roller shutter, refer to that a kind of cylinder of roller shutter improves structure.
Background technology
Roller shutter is a kind of curtain generally using in daily life, conventionally system head (containing bead), tail processed, connector, reel (or claiming spool), underbeam (or claiming lower rail) and cord, consists of.It is simple in structure, easy to use, so liked by everybody, uses very extensive.
The part but roller shutter also comes with some shortcomings, mainly, the roller shutter of existing use is mainly to rely on reel to carry out roll-up window shade, and by reel as the structure that supports curtain.In order not take excessive space, the reel of existing roller shutter is all thinner, and relies on the head processed (containing bead) of the micro-one end of volume that rotatory force is provided while rotating, and relies on to slide and rotate between the existing head processed using and reel, and the power needing during rotation is larger.Particularly at roller shutter, use after a period of time, reel produces certain bending, and at this moment rotatory force increases, and can cause system head to damage.
On the other hand, the frictional force between reel and the curtain of existing roller shutter is larger, is also an impact reason in a system life-span.
Summary of the invention
The object of the invention is that the reel of existing use is proposed to one and improve structure, by the technical program, reduce the torsion of system head when rotating drum, and can reduce the frictional force between reel and curtain.
The present invention is achieved by the following technical solutions:
An improvement structure for curtain cylinder, reel comprises the roll bar of two Parallel Symmetrics, gapped between described roll bar; Described roll bar two ends are provided with connection cover; The surface that described two roll bar ends are connected with connection cover is provided with tooth-shape structure, and the inner surface of described connection cover is provided with the tooth-shape structure matching with roll bar end tooth-shape structure; The side external surface of described connection cover is also tooth-shape structure, and described tooth-shape structure is that profile of tooth is rotationally connected with system head and tail processed.
The described two relative surfaces of bar roll bar are provided with the multiple and axial perpendicular grooves of roll bar.
Described adjacent two grooves are parallel.
Coupling part between the face that described each groove is adjacent is circular arc.
Described roll bar is hollow section.
The interposition of described connection cover is equipped with raised structures, and described raised structures is arranged at the end between two roll bars.
The invention has the beneficial effects as follows:
By technical scheme of the present invention, by tooth-shape structure, carry out transferring power, improve the transmission efficiency of power and the power while reducing to rotate roll bar, and reduced the parts of roller shutter, also reduced the friction factor between reel and cord.
Accompanying drawing explanation
Fig. 1 is the structural representation of reel;
Fig. 2 is the structural representation of connection cover.
The specific embodiment
Describe by the following examples technical scheme of the present invention in detail, should be understood that, following embodiment is only exemplary, only can be used for explaining and technical scheme of the present invention being described, and can not to be interpreted as is the restriction to technical solution of the present invention.
As depicted in figs. 1 and 2, a kind of improvement structure of curtain cylinder, reel comprises the roll bar 2 of two Parallel Symmetrics, in the present embodiment, roll bar 2 is hollow section.
Gapped between described roll bar 2, for passing cord; Described roll bar 2 two ends are provided with connection cover 1; The surface that described two roll bar ends are connected with connection cover is provided with tooth-shape structure 3, and the inner surface of described connection cover is provided with the tooth-shape structure matching with roll bar end tooth-shape structure; The side external surface of described connection cover 1 is also tooth-shape structure 5, and described tooth-shape structure is that profile of tooth is rotationally connected with system head and tail processed.The interposition of described connection cover is equipped with raised structures 4, and described raised structures 4 is arranged at the place, tip-clearance between two roll bars.In other embodiment of the technical program, also can adopt not the locating piece being structure as a whole with connection cover that two roll bars are divided into certain gap.
The described two relative surfaces of bar roll bar are provided with axially vertical and parallel groove (not shown) of multiple and roll bar.Coupling part between the face that each groove is adjacent is circular arc.
Although illustrated and described embodiments of the invention, for the ordinary skill in the art, be appreciated that without departing from the principles and spirit of the present invention and can carry out multiple variation, modification, replacement and modification to these embodiment, scope of the present invention is by claims and be equal to and limit.
