Technical field
The utility model belongs to roller shutter and makes the field, relates to the improvement of self-rolling reel, is a kind of self-rolling reel specifically.
Background technology
The self-rolling reel is a kind of element that uses torsion spring as store energy, is made up of a spool, reel, torsion spring and two ends plug usually.Torsion spring is a kind of compact arranged helicoidal structure with unified diameter that is rolled into by elasticity steel wire.When torsion spring was subjected to external force such as torsion, the energy that elastic force was produced when torsion spring changed its morpheme stored.After the external force that changes the torsion spring morpheme disappeared, torsion spring discharged by energy and makes reel get back to the original position.The self-rolling reel is used to make the protection roller shutter of machine instrument.In addition, can also be applied to make the protection roller shutter etc. of roller shutter anti-mosquito screen window, garage rolling screen door and the door and window of door and window.
How the difference of the method for the making of self-rolling reel just is torsion spring and spool and reel are coupled together.A kind of structure that Germany unexpected rival (HEMA) mechanical device Securi-Tec Ltd. (IE) Baybush, Straffan, Country Kildare, Ireland uses is for being fixed on an end of torsion spring on the plug on the reel by a screw thread structure, and the other end of torsion spring then directly or by a joint is fixed on the spool.Yet when torsion spring was subjected to torsional interaction, the diameter of torsion spring diminished, thereby made the length of torsion spring elongated.Because the two ends of torsion spring all are fixed, when twisting, there is not flexible leeway.Therefore, when being fixed on torsion spring on the spool, torsion spring must be drawn back a segment distance,, and just make torsion spring be in the state of stretching all the time like this, shorten the serviceable life of torsion spring so that stay required space of when distortion to torsion spring.Europe patent (EP1291485A1) discloses a kind of self-rolling reel, has improved the structure of German unexpected rival (HEMA) company.This self-rolling reel structure does not have through spool, uses the plug of two separation to replace spool so that fix with casing or reel holder, and one of them plug stretches within the reel.One end of torsion spring is fixed on stretching on the interior part of reel of this plug.Reel can rotate with respect to plug by a cushion block.The other end of torsion spring is fixed on the contiguous block that is positioned at reel.Be bumped into a key on the contiguous block, in the slotted hole that this key insertion spool shaft makes progress.Because the effect of key can guarantee that contiguous block rotates with reel.Because key is arranged in the reel axial long hole, contiguous block can move axially along reel.Therefore, guaranteed that not only torsion spring keeps the original-shape that does not stress under situation about not stressing, and guaranteed torsion spring freely stretching on the reel axial direction under stressing conditions.Because total system is to be based upon on two two plugs that are separated from each other, in other words, be to build on a virtual spool, therefore, total system is a unsettled system, and is high to requirement on machining accuracy.In addition,, therefore, on thin-walled, open slotted hole and not only damage feather key easily, and feather key also damages reel easily, thereby shorten the serviceable life of reel because reel is generally thin-wall construction.
Therefore, how to improve the structure of self-rolling reel, guaranteeing to make one-piece construction stable under the torsion spring prerequisite in serviceable life, reliable transmission, and reel is not fragile, this is the technical task that needs to be resolved hurrily at present.
Summary of the invention
The purpose of this utility model is the problem that exists at existing self-rolling reel, and a kind of self-rolling reel is provided, by changing the structure of self-rolling reel, guaranteeing under the torsion spring prerequisite in serviceable life, make one-piece construction stable, reliable transmission, and reel is not fragile.
The purpose of this utility model is achieved by the following technical solution: a kind of self-rolling reel, comprise reel, spool in the reel, be enclosed within the torsion spring on the spool, two plugs at reel two ends, it is characterized in that having in described two plugs a plug extends in reel one section fixedly connected with an end of described torsion spring, go up kink one slide block for one section in the middle of the described spool, inner face that described slide block contacts with spool and spool outside match, slide block can endwisely slipping along spool, and can rotate with spool, slide block is fixedlyed connected with the other end of torsion spring, described spool two ends are right cylinder, insert in the middle hole of two plugs at the spool two ends, and two plugs can slide with respect to spool.
Be threaded screw thread on one section of the described plug of fixedlying connected with torsion spring, fixedly connected with an end of torsion spring by the screw thread screw thread, described slide block also is threaded screw thread, and fixedlys connected with the other end of torsion spring by the screw thread screw thread.
For the xsect of section bar shape is a kind of in triangle, four limit types, six squares, the spline type, the slide block interstitial hole has and identical cross section, spool intermediate proximate matter cross section in the middle of the described spool.
The utility model compared with prior art has following advantage and good effect:
A plug of the utility model reel extend in reel one section is fixedlyed connected with an end of described torsion spring, go up kink one slide block for one section in the middle of the described spool, inner face that described slide block contacts with spool and spool outside match, slide block can be along the endwisely slipping of spool, and can rotate with spool.When external force drove reel and rotates with respect to spool, the drive of an end of torsion spring by an end plug was along with reel rotates, and the other end is fixed on the slide block.The reel scrolling tightens torsion spring, makes that the torsion spring diameter diminishes, the elongation of torsion spring length, and torsion spring drives slide block and slides along spool; When external force disappeared, torsion spring discharged the energy that stores in it, and reel is restored to the original state.Simultaneously, torsion spring diameter and length return to original state of nature, and like this, torsion spring does not stress, and can guarantee serviceable life; Spool runs through reel, and slide block slides on spool, does not contact with reel, makes one-piece construction stable, reliable transmission, and reel is not fragile.
