Abstract

The utility model relates to a manual booster device of a torsional spring for a roller shutter door. The utility model is composed of a connecting shaft which has the structure that a bearing seat is connected with a bearing and a clamping ring, an elastic device on the connecting shaft and a clutch, wherein, the elastic device is the torsion spring connected to a centering shaft, and both ends are respectively connected to the connecting shaft which is fixed in a door shaft and a torsion spring seat which is fixed on the connecting shaft; the clutch is also fixed on the door shaft and is formed by the matching of a tooth rod which is connected to a lock body and a gear seat which is connected with a driving head. The device is totally arranged in an inner shaft of the roller shutter door; when the utility model is used when power is cut off, the tooth rod on the lock body is pulled to rotate in 90 DEG to make the clutch disengaged, and the roller shutter door can be pulled by hands. The utility model has the advantages of compact structure, small size, neat and fresh appearance, convenient use, high safety, labor saving and time saving.

Description

The manual booster of rolling door torsion spring

Technical field

The utility model relates to a kind of being installed in the door-hinge and the matching used servicing unit of rolling door, when having a power failure or motor breaks down can't open and close rolling door the time, availablely manually opens and closes the manual booster of rolling door torsion spring that rolling door is used.

Background technology

Because attractive in appearance, the style of rewindable metal curtain door, the side of occupation of land, esy to use, safe and reliable not more and more are subjected to the favor of businessman.But when having a power failure or motor when breaking down, just very time-consuming with pulling moving rolling door, effort.

It is a kind of when having a power failure that the patent No. 96232696.8 " electric-hand driven two-purpose rolling door " just provides, the available dual-purpose rolling door that manually opens and closes the rolling door use, but its structure is simple not enough, and part is many, and volume is big.

Summary of the invention

Technical problem to be solved in the utility model is: provide a kind of rolling door torsion spring manual booster, be installed in the door-hinge of rolling door, when not having electricity and the supporting use of rolling door, it is simple in structure, compact, volume is little, convenient manual operation, safely, save time, laborsaving.

The utility model solves the problems of the technologies described above the scheme that is adopted: the manual booster of rolling door torsion spring is by the axle that connects that is connected with bearing, collar on the bearing support, the elastic device and the clutch that connect on the axle are formed, described elastic device is the torsion spring that is connected on the centration axis, its two ends are connected to and are fixed on the interior centration axis of door-hinge and are fixed on the torsion spring seat that connects on the axle, described clutch also is fixed on the door-hinge, is made of with the pinion stand cooperation that is connected with driving head the ratch that is connected on the lock body.

Compared with prior art, advantage of the present utility model is: all be installed in because of this device in the door-hinge of rolling door, directly be connected with the roller shutter motor reducer, its compact conformation, volume is little, appearance is clean and tidy, salubrious.Only need the ratch on the pulling lock body to rotate 90 degree, make throw-out-of clutch, leave behind with regard to available have gentle hands pine or roll rolling door by the elastic force of torsion spring, easy to use, save time, laborsaving.If electric operating, when rolling door is left behind when closing, the torsion spring storage energy of not working, and roll when opening when rolling door, torsion spring just discharges elastic force, assists motor to work together, balanced motor rises, the load when descending, and it is close, thereby improves the supporting capacity 30% of motor.

Description of drawings Fig. 1, structural representation of the present utility model.Fig. 2, clutches engaged state diagram.Fig. 3, throw-out-of clutch state diagram.

The specific embodiment

Embodiment is further described the utility model below in conjunction with accompanying drawing:

By user installation position, direction, need decision, torsion spring 4 is selected for use left-handed or dextrorotation, torsion spring 4 can be installed in a left side or the right-hand member of door-hinge 19, corresponding clutch is installed in the right side or the left end of door-hinge 19.

The centre of ratch 16 is provided with even teeth, and anodontia at 1/4 place of periphery.

Clutch is installed in by locking closure 21 by ratch 16, in the lock body that lock 20 constitutes, lock 20 is fixed on the pinion stand 17, pinion stand 17 is screwed in the termination of door-hinge 19 by clamping ring, ratch 16 cooperates with roller gear on pinion stand 17 1 ends, pinion stand 17 in addition end and door-hinge 19 interior driving heads 18 be connected constitute.Driving head 18 fuses by steel pipe and roller shutter motor.

Torsion spring seat 7 is the annular of band shoulder hole.

Be fixed with bearing support 8 in one end of door-hinge 19, be connected with in its hole tape spool hold 10 and back-up ring 11 connect axle 9, connect the side's of having core 13 on axle 9 the end, end is fixed on the end of torsion spring seat 7 with screw 5 in addition.

The vertical end of centration axis 1 is screwed in door-hinge 19, torsion spring 4 is enclosed within outside the centration axis 1, the horizontal ends of centration axis 1 is connected in the shoulder hole of torsion spring seat 7 one ends movingly, screw 2,5 is used at the two ends of torsion spring 4 respectively, pad 3,6 is fixed on centration axis 1 and the torsion spring seat 7, connect axle one end of 9 side's of having cores 13 and the joint pin on the lock body with in the locating ring 12 on screw, the pin 14 fixing two stands plates 15 on the wall, the side's of adjusting core 13 during assembling, suitably tighten up torsion spring 4, make it produce certain initial torsion.

Need close when leaving behind rolling door when power failure, as long as the ratch 16 on the pulling lock body, it is rotated 90 degree, make ratch 16 throw off the engagement that cogs with pinion stand 17, as shown in Figure 3, at this moment as long as spur rolling door downwards with hand, rolling door descends under the deadweight effect and closes, and torsion spring 4 constantly tightens up energy storage in the decline process simultaneously.Opposite only with hand upwards promotes rolling door if will open rolling door, and under the assistance of elastic force, rolling door scrolls up and opens.

Have electricity to need must to spur the ratch 16 on the lock body again when electronic, it rotated 90 degree again, make on ratch 16 and the pinion stand 17 gears engaged as shown in Figure 2.
