Abstract
The utility model relates to a roll up the technical field of curtain, indicate a roll up curtain controlling means especially. Including the reelpipe, the reelpipe both ends are equipped with left and right support, the reelpipe hole is the square hole, be equipped with the bearing in the right branch props, the bearing is connected with core pipe end head, and core pipe end head and core union coupling are equipped with left and right torsional spring cover in proper order on the core pipe, the left torsional spring cover outside and the cooperation of reelpipe hole, and left torsional spring cover is inboard manages clearance fit with the core, and right torsional spring cover is fixed on the core pipe, left and right torsional spring cover and torsional spring threaded connection. The beneficial effects of the utility model are that: the orientation was freely slided about left side torsional spring overlapped in the reelpipe, avoided the torsional spring to twist at torsional in -process, and the book curtain is operated smoothly, just avoided the reelpipe inner wall production noise because the distortion of torsional spring rubs, the right branch props to be connected through bearing and core pipe end head, and sliding friction becomes rolling friction, and the reduction right branch props the wearing and tearing with core pipe end head, prolongs the life -span of product, reduces torsional resistance.
Description
Technical field
The utility model relates to roller shutter technical field, espespecially a kind of rolling shutter control device.
Background technology
Existing night curtain structure, apart from the night laterally pulled outside curtain, separately there is a kind of roller shutter structure that can longitudinally pull, and on the whole general roller shutter structure is be provided with a controller in the roll bar one end being wound with roller shutter cloth, in controller and roll bar the other end then each group be provided with the fixing side frame that can be fixed on metope, on controller, be provided with a stay cord simultaneously, user can be allowed whereby when pulling stay cord, controlling the lifting of roller shutter cloth by means of controller.Torsion spring structure in controller, in the process rotated, torsion spring generation elastic deformation, causes roller shutter to operate and has some setbacks, controller to night curtain the backrush strength that provides of pipe crimping and action excessive, when causing curtain backrush at night, easily produce larger vibrations and noise.
Summary of the invention
The purpose of this utility model is: provide a kind of rolling shutter control device, solves in prior art, controller to night curtain the backrush strength that provides of pipe crimping and action excessive, when causing curtain backrush at night, easily produce the problem of larger vibrations and noise.
For reaching above-mentioned purpose, the technical solution that the utility model proposes is: rolling shutter control device, comprise pipe crimping, pipe crimping two ends are provided with left and right support, described pipe crimping endoporus is square hole, bearing is provided with in described right support, bearing is connected with core pipe end, core pipe end is connected with core pipe, core pipe is provided with left and right torsion spring set successively, with pipe crimping inner hole outside left torsion spring set, coordinates with core ligament inside left torsion spring set, right torsion spring set is fixed on core pipe, and left and right torsion spring set is threaded with torsion spring.
Described bearing is ball bearing.
Described right torsion spring set adopts pin to be fixed on core pipe.
The beneficial effects of the utility model are: left torsion spring set left and right directions in pipe crimping is free to slide, and avoid torsion spring distortion in the process reversed, roller shutter operation is smooth and easy, and avoid because the distortion friction pipe crimping inwall of torsion spring produces noise; Right support is connected with core pipe end by bearing, and sliding friction becomes rolling friction, reduces the wearing and tearing of right support and core pipe end, extends the life-span of product, reduces the resistance reversed.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Reference numeral: 1, right torsion spring set, 2, right support, 3, core pipe end, 4, bearing, 5, core pipe, 6, torsion spring, 7, left torsion spring set, 8, pipe crimping, 9, left support.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described further.
As shown in Figure 1, rolling shutter control device, comprises pipe crimping 8, pipe crimping two ends are provided with left and right support, and described pipe crimping 8 endoporus is square hole, is provided with bearing 4 in described right support, bearing adopts ball bearing, bearing 4 is connected with core pipe end 3, and core pipe end 3 is connected with core pipe 5, and core pipe 5 is provided with left and right torsion spring set successively, with pipe crimping 8 inner hole outside left torsion spring set 7, with core pipe 5 matched in clearance inside left torsion spring set 7, right torsion spring set 1 and core pipe 5 adopt sells fixing, and left and right torsion spring set is threaded with torsion spring 6.Left support 9 is connected with axis of rotation, and axis of rotation is connected with support, and core pipe end 3 is fixed by screws on support.
Left torsion spring set of the present utility model left and right directions in pipe crimping is free to slide, and avoid torsion spring distortion in the process reversed, roller shutter operation is smooth and easy, and avoids because the distortion friction pipe crimping inwall of torsion spring produces noise; Right support is connected with core pipe end by bearing, and sliding friction becomes rolling friction, reduces the wearing and tearing of right support and core pipe end, extends the life-span of product, reduces the resistance reversed.
Claims (3)
