Abstract
The utility model discloses a multipurpose curtain rolling device composed of a drive drum, cord fabric, a centrifugal brake and a helical spring. The utility model is characterized in that the drive drum uses the helical spring arranged in the drive drum to provide and store drive energy, and uses the centrifugal brake to control drive. The cord fabric rolled on the drive drum is pulled by hands to freely upward and downwards roll, unroll, stay and reset. The utility model has the advantages of simple operation and use, reliable action and wide purpose. The utility model not only can be used as a curtain, but also can be widely used for school wall maps, photography setting, etc.
Description
The utility model relates to a kind of multipurpose screen-roller, and the particularly a kind of multipurpose screen-roller that can roll automatically and arbitrarily brake belongs to general daily necessities.
At present, the curtain product that people generally use belongs to translation mostly to be split and separates the form that hangs with cord, adopts the curtain of this form, removes the travelling mechanism more complicated, operation troubles how outside, the decorative effect of curtain is also not satisfactory.
The multipurpose screen-roller that the purpose of this utility model provides a kind of simple in structure, reliable in action, can open up and down and can arbitrarily brake.
For achieving the above object, the utility model by a drive drum that has a centrifugal brake and volume thereon cord and be contained in coil type spring in the reel etc. and form.Transmission energy of the present utility model relies on a coil spring that is contained in the reel to provide.The right-hand member spring head of coil spring is fixed on the right-hand member spring head fixed axis that links to each other with reel, the left end spring head of coil spring is fixed on the left end spring head fixed axis that links to each other with the brake star-wheel, star-wheel and its coaxial out star wheel and the ball that is contained between teeth groove constitute centrifugal brake, out star wheel is contained in the left end of reel and becomes stationary fit with reel, operation principle of the present utility model is: install the back and earlier cord is twisted on the reel, when needs launch curtain, when spurring cord downwards with hand, cord just drives the out star wheel and the right-hand member spring head fixed axis of reel and brake and does counterclockwise to rotate, and star-wheel does not rotate, the left end of spring head does not just rotate yet, coil spring screws and automatic energy accumulating gradually from right-hand member, at this moment, because of the ball in the brake can enter in the cavity of out star wheel all the time, mechanism can not locking, cord can spur downwards always, when needs rest on a certain position with cord, behind the downward pulling force of slowly removing cord, though out star wheel is subjected to the torsional interaction attempt reversed turning of spring, but because the ball in brake out star wheel cavity was fallen between the teeth groove of star-wheel automatically because of gravitate originally, the out star wheel reversed turning is obstructed, mechanism's self-locking.When needs are regained cord, only need slight pulling cord downwards, to decontrol suddenly then, out star wheel is because of being subjected to the torsional interaction high speed rotary of spring, and the centrifugal force of generation is brought ball into again in its cavity, and mechanism can't locking, and cord is rolled automatically.
Compared with prior art, advantage of the present utility model is:
(1), compact conformation, easy for installation, simple to operate, reliable in action can arbitrarily be opened a book and stop.
(2), the utility model is of many uses, except that making general curtain, also can be widely used in take pictures background and school wall map etc.
Description of drawings:
Fig. 1 is a cutaway view of the present utility model
Fig. 2 is the braking schematic diagram of centrifugal brake of the present utility model
Fig. 3 is the work sheet of centrifugal brake of the present utility model
Below in conjunction with drawings and Examples the utility model is described further.
As shown in Figure 1, the utility model is made of running part, brake portion and cord three parts, wherein running part is by reel (4), coil type spring (5), left end spring head fixed axis (6), spring outer catheter (7), inner catheter (8), right-hand member spring head fixed axis (9), right wheel hub (10) are formed, and brake portion is made up of star-wheel (2), out star wheel (3) and ball (1), and cord part comprises cord (11) and sleeve pipe (2).As seen from Figure 1, technical characterictic of the present utility model is: reel (4) and the out star wheel (3) that is contained in the centrifugal brake of one end are that stationary fit is installed, the left end of star-wheel of centrifugal brake (2) and coil spring (5) is fixed together, the right-hand member of coil spring (5) is fixed on and reel (4), becomes on the right-hand member spring head fixed axis (9) of stationary fit installation.When launching cord (11), cord (11) drives reel (4) and out star wheel (3) and right-hand member spring head fixed axis (9) and plays rotation, and coil spring (5) begins to screw and automatic energy accumulating gradually from right-hand member.As shown in Figure 1, star-wheel of centrifugal brake of the present utility model (2) and out star wheel (3) are the concentric assemblings, in the cavity (A) between star-wheel (2) and out star wheel (3) ball (1) are housed.By Fig. 2, Fig. 3 as can be known, the star-wheel of centrifugal brake of the present utility model (2) is a pocket-wheel that is processed with double wedge, and out star wheel (3) is a pocket-wheel that is processed with cavity (A).
When the utility model used, when launching cord (11), out star wheel (3) rotated counterclockwise, and star-wheel (2) does not rotate.Ball (1) is fallen into (see figure 2) in the teeth groove of star-wheel (2) because of gravitate, at this moment, attempts clockwise rotating out star wheel (3) and reel (4) because of being subjected to the obstruction self-locking of ball (1) under coil spring (5) torsional interaction.In the time will rolling cord (11), spur cord (11) earlier downwards, out star wheel (3) drives in the next teeth groove that 90 ° of ball (1) revolutions enter star-wheel (2), mechanism can not self-locking, but when ball (1) was taken to the crown of star-wheel (2) by out star wheel (3), when removing pulling force suddenly, the centrifugal force that rapid rotating out star wheel (3) produces under spring (5) torsional interaction can be brought ball (1) again in its cavity (A), mechanism still can not self-locking, and cord (11) is by automatic drawing back.
Claims (3)
1. a kind of multipurpose screen-roller of forming such as a centrifugal brake that mainly constitutes by reel (4), coil spring (5), cord (11) and by star-wheel (2), out star wheel (3) and ball (1), it is characterized in that: reel (4) and the out star wheel (3) that is contained in the centrifugal brake of one end are that stationary fit is installed, the left end of star-wheel of centrifugal brake (2) and coil spring (5) is fixed together, and the right-hand member of coil spring (5) is fixed on the right-hand member spring head fixed axis (9) that becomes the stationary fit installation with reel (4).
2. according to claims 1 described a kind of multipurpose screen-roller, it is characterized in that: star-wheel of above-mentioned centrifugal brake (2) and out star wheel (3) are the concentric assemblings, in the cavity (A) between star-wheel (2) and out star wheel (3) ball (1) are housed.
3. it is characterized in that according to claims 1 described a kind of multipurpose screen-roller: the star-wheel of above-mentioned centrifugal brake (2) is a pocket-wheel that is processed with double wedge, and the out star wheel of above-mentioned centrifugal brake (3) is a pocket-wheel that is processed with cavity (A).
