Description
Technical field
The utility model relates to rolling screen door technical field more particularly to a kind of rolling screen door reels that can adjust torsional spring torsion.
Background technique
Hand rolling door finds broad application since structure is simple in places such as StoreFront, market, garages, hand rolling door
Generally by the spool being fixedly connected with supporting plate, the reel being rotatablely connected with spool, torsional spring, guide rail and the winding being located in reel
Roller shutter outside reel is constituted, and the effect of torsional spring is to keep switch rolling screen door laborsaving, when putting down roller shutter manually, roller shutter
The elongated change weight of hanging portion, spool turns drive torsional spring tightening, and elastic force increases, the gravity of roller shutter hanging portion and the bullet of torsional spring
Power is in equilibrium state, its gravitional force is converted into the elastic potential energy of torsional spring during roller shutter decline；When opening roller shutter manually, volume
Curtain rises, and hanging portion gravity reduces, and reel drives torsional spring to follow diastole, and elastic force reduces, the gravity of roller shutter hanging portion
With the elastic force of torsional spring still in equilibrium state, in roller shutter uphill process, the elastic potential energy of torsional spring is converted into the gravitional force of roller shutter,
As long as roller shutter overcomes the frictional force between rolling screen guiding rail during raising and lowering, compare province with hand switch roller shutter
Power.General rolling screen door will stay certain length in guide rail after opening, that is, have the roller shutter of certain length to keep hang, do not have
All it is wrapped on reel.In order to keep sagging length appropriate, must just apply centainly to torsional spring after the installation is completed in reel
Torsion, so that the stress of roller shutter keeps balance.The existing method for applying torsion is to have the side of spool turns in arms with hand using more people
Method is operated, and since the installation site of reel is higher, this method is time-consuming and laborious.
Utility model content
In view of the above-mentioned problems of the prior art, the utility model provides a kind of rolling screen door that can adjust torsional spring torsion
Reel, facilitates adjustment torsional spring torsion, and structure is simple.
The utility model is achieved through the following technical solutions:
A kind of rolling screen door reel that can adjust torsional spring torsion, including be fixedly connected with supporting plate spool, cover outside spool
The reel that is rotatablely connected with it covers the torsional spring being attached in reel in spool；It is equipped with adjustment wheel, anti-lever in the reel and prevents
Dynamic pin；The adjustment wheel and spool are rotatablely connected and cannot slide axially on spool, and excircle is equipped with several openings outwardly
Radial counterbore, the circumferentially spaced setting of counterbore；The anti-lever be set to adjustment wheel radial on the outside of, the anti-lever and
Spool is fixedly connected；The anti-dynamic pin and counterbore match, and one end that it is located at outside counterbore after the anti-dynamic pin insertion counterbore is reliable
In anti-lever；The reel of adjustment wheel corresponding position is equipped with multiple flutings；One end of the torsional spring and mandrel interior wall are solid
Fixed connection, the other end are fixedly connected with adjustment wheel；It further include adjustment bar, the adjustment bar may pass through fluting and inject in counterbore,
The diameter of diameter and counterbore matches.
As a further improvement, the counterbore along the circumferential direction spaced set.The torsion of torsional spring can be carried out so equal
It is even whole.
As a further improvement, the fluting is equipped with 3.It is conveniently adjusted torsional spring torsion.
The beneficial effects of the utility model are: several counterbores are arranged on adjustment wheel in one end connection adjustment wheel of torsional spring,
The torsion of torsional spring is adjusted using the method for adjustment bar rotation adjustment wheel, and the anti-dynamic pin being inserted in counterbore is used to lean against anti-lever
On method prevent adjustment wheel from rotated round about to keep the torsion of torsional spring, both facilitate the torsion of adjustment torsional spring, structure is again
Simply.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the cross-sectional view of the A-A of Fig. 1.
Fig. 3 is the structural schematic diagram of the adjustment bar of the utility model.
In figure: supporting plate 1, spool 2, reel 3, torsional spring 4, adjustment wheel 5, anti-lever 6 prevent that dynamic pin 7, counterbore 8, fluting 9 are adjusted
Whole bar 10.
Specific embodiment
As shown in Figure 1-3, the embodiments of the present invention, including be fixedly connected with supporting plate 1 spool 2, cover in spool 2
The reel 3 that is rotatablely connected outside with it covers the torsional spring 4 being attached in reel 3 in spool 2；It is equipped with adjustment wheel 5 in the reel 3, prevents
Lever 6 and anti-dynamic pin 7；The adjustment wheel 5 and spool 2 are rotatablely connected and cannot slide axially on spool 2, and excircle is equipped with
The radial counterbore 8 of several openings outwardly, uniformly to be adjusted convenient for the torsion to torsional spring 4, counterbore 8 is along the circumferential direction equidistant
Setting；The anti-lever 6 is set to adjustment 5 radial outsides of wheel, which is fixedly connected with spool 2；It is described to prevent dynamic pin 7 and sink
Hole 8 matches, it, which is located at one end outside counterbore 8, after the anti-dynamic insertion of pin 7 counterbore 8 can lean against in anti-lever 6；The adjustment wheel 5
The reel 3 of corresponding position is equipped with 3 flutings 9, and 3 flutings 9, which are arranged, can facilitate the torsion of adjustment torsional spring 4；The one of the torsional spring 4
End is fixedly connected with 3 inner wall of reel, and the other end is fixedly connected with adjustment wheel 5；It further include adjustment bar 10, the adjustment bar 10 can be worn
It crosses fluting 9 to inject in counterbore 8, the diameter of diameter and counterbore 8 matches.
Working principle is: when the torsion of discovery torsional spring 4 and the weight of roller shutter mismatch, when needing to increase the torsion of torsional spring 4,
It first closes rolling screen door and exposes fluting 9, bar 10 will be adjusted in the counterbore 8 that fluting 9 injects adjustment wheel 5 to the side for tightening torsional spring 4
To rotation adjustment wheel 5, since reel 3 hangs roller shutter, reel 3 will not be rotated and then, and 5 rotation of adjustment wheel drives torsional spring 4 to rotate, and be turned round
Its torsion just changes after spring 4 rotates, and the anti-pin 7 that moves leaned against in anti-lever 6 at this time and then can be rotated away from anti-move by adjustment wheel 5
Bar 6 removes anti-dynamic pin 7, injects the counterbore 8 nearest from anti-lever 6, and after back unclamping adjustment bar 10, adjustment wheel 5 can be in torsional spring 4
It is turned round under the action of torsion, leans against anti-dynamic pin 7 again in anti-lever 6, then removed adjustment bar 10 and convert counterbore 8 to tightening torsional spring
4 direction continues to rotate adjustment wheel 5, then removes anti-dynamic pin 7, injects the counterbore 8 nearest from anti-lever 6, unclamps adjustment further back
It leans against anti-dynamic pin 7 again in anti-lever 6, repeatedly, torsional spring 4 can be gradually tightened, to increase the torsion of torsional spring 4
Power；When reducing the torsion of torsional spring 4, as long as adjustment wheel 5 is rotated toward opposite direction.After the torsion adjustment of torsional spring 4,
Hand rolling door can normal use, by pull rolling screen door can carry out switch roller shutter door operation, in the power-assisted of torsional spring
Under, switch rolling screen door is more light.
Above description is only a specific implementation of the present invention, but the protection scope of the utility model is not limited to
In this, any change or replacement expected without creative work be should be covered within the scope of the utility model.
