Description

A kind of improvement mechanism of rapid door

The present invention relates to a kind of improvement mechanism of rapid door, especially a kind of roller shutter structure of electric rolling door.

In factory, electric rolling door generally can usually be seen in school and many public places, no matter it be household or factory all someone installs, especially the thick place of narrow people on ground, especially suitable, because its characteristics of rolling door are and can go up, following contraction is rolled, but after the permanent use of rolling door, its torque spring has lax, so all can be provided with a spool adjusting device in the rolling door outside, the patent gazette of No. the 368046th, Taiwan patent announcement shown in annex one, the rolling door spool adjusting device that should habitually practise, the application of force that is fixed in rolling door spool one end perforated outer for group is constructed, and it is by main body 31, bolting element 32, nut 33 and operation tool 34 are formed; Wherein: main body 31, the H shape ring body of forming by two side shields 311 and polygon crosspiece 312, the center is horizontally set with one and wears axis hole 313, and offers a perforating hole 314 on the one corresponding sides of polygon crosspiece 312, and establishes respectively to justify shrinkage pool 315 and hexagonal shrinkage pool 316 in two ends of perforating hole 314; Bolting element 32 can be worn the perforating hole 314 that passes through main body 31 and the perforation 11 of spool 1, and pole face is provided with the body of rod of pin thread, and its head can be placed in the round shrinkage pool 315 inner persons of main body 31; Nut 33, inside are provided with pin thread and can wear with bolting element 32 and pass through the hexagonal elements that end should screw togather, and it can be placed in the hexagonal shrinkage pool 316 inner persons of main body 31; Operation tool 34, but clamping in the polygon crosspiece 312 one corresponding sides of main body 31, with the force application element of rotating scroll 1, its end 341 default internal diameters and polygon crosspiece 312 corresponding sides are apart from identical clamping cut person.It can utilize the force application element of an operation tool 34 rotating scrolls 1, utilize force application element to rotate rolling door spool 1, and then reach and screw the torque spring purpose, but it must stretch into operation tool 34 in the main body 31, and behind the polygon crosspiece 312 of clamping main body 31 inboards, can rotate main body 31, and rolling door is installed between roof and the ceiling usually or when being loaded on the doorway upper outer outward, promptly need install an iron sheet additional coats rolling door, and when roller door arrangement is between roof and smallpox, rolling door is installed in its space usually just, as will screw the torque spring of spool 1 time, it promptly can cause the operating space narrow and small, quite be not awkward person's operation aperture spanner, in addition, the operator need climb up on the supporter again, can operate turn spool 1, as the operator accidentally, promptly can cause accident, and for example be when exposing to the top, doorway, it is to ask attractive in appearance all can cover just boring suitcase usually, when it tightens torque spring as wanting turn spool 1, it can also be very little not easy to operate for the operating space, moreover when the operator uses operation tool 34, it is because of the restriction in space, can only work as when turning to an angle, promptly need to extract operation tool 34 out main body 31, after changing an angle, insert main body 31 again and rotate, it is quite not convenient, too narrow and small words in operating space and for example, promptly can cause the operator to be inconvenient to exert oneself and rotate main body 31, no matter habitual roller door arrangement is between roof and the smallpox or in the top, doorway, how can be at the relative position that is provided with the spool adjusting device, be provided with a lid that can upwards start or open downwards, keep in repair or adjust the spool adjusting device of rolling door with convenient for maintaining person by this place.

The patent gazette of No. the 248242nd, Taiwan patent announcement shown in annex two, the spool spring tightness guiding mechanism of rolling door that should be habitual, be sheathed several rolling wheels 50 and spring 40 and set firmly several fixed blocks 41 on spool 10, spring 40 1 sides are installed on the rolling wheel 50, opposite side then is installed on the fixed block 41, rolling door 80 1 ends are installed on disk 51 and each rolling wheel 50, and disk 51 is driven by the motor 71 of holder 70, wherein: be provided with a fixed bin 60 and be arranged with holder 70 at spool 10 1 ends, fixed bin 60 is provided with the axis hole 62 that can be equipped with spool 10, one guide hole 64 is set again in the top, and portion is provided with a worm gear 20 and a worm screw 30 that cooperates with worm gear 20 that is installed on the spool 10 within it, the axle 31 of worm screw 30 is provided with groove 32, and the axle 31 of worm screw 30 is arranged in the guide hole 64, aforesaid fixed bin 60 can be fixing with the holder 70 that is set on the spool 10, should habitual rolling door be to utilize a worm gear 20 to cooperate worm screw 30 to limit the rotation of spool 10, but when rotating rolling door 80, promptly can cause the vibrations of worm gear 20 and worm screw 30, because of being to utilize the thread engaged transmission between worm gear 20 and the worm screw 30, and the vibrations of worm gear 20 and worm screw 30, and its thread that is meshed also can be shaken, and the result of vibrations promptly can cause its spiral angle loosening, and make the spring 40 of spool 10 more and more loose, and cause danger easily.

The structure-improved that the purpose of this invention is to provide a kind of rapid door, make the customer can adjust the tightness of torque spring fast, easily, and adjusted the tightness of torque spring as the customer after, can utilize initiatively with passive adjusting device in the setting of flywheel, torque spring can't be reversed discharge its elastic potential energy, in the time of can preventing to use rolling door, vibrations that produced and cause the loosening of worm gear, and the elastic potential energy of torque spring is released.
