Detailed description of the invention
With reference now to Fig. 1, be illustrated according to suspension of the present invention and arrangement for adjusting height 10, wherein can see, cable 50 from described device out, be set to for fixing an object (not shown) or its part, to support in suspension from described device with the distance that is determined; Conversely, by rising to the bait 16, described device is fixed to an external stability support member (not shown), as ceiling, beam etc.Fig. 1 also show a band wing nut 15 or has the nut of other shape or material, and its tightness relates to the accordingly friction of cable winding on spool.Therefore, described cable can bear heavier or lighter load, still leave vacant to turn back to this device, i.e. debatching on spool.
Forward Fig. 2 to now, an exploded perspective illustrates all component of device 10, and wherein, described housing is made up of two and half shells, i.e. fore shell 12 and back cover 14, and both is all provided with upper and lower projection.Connected by a buckle in the pin 12a to the hole 14a of back cover of fore shell up, and in below by preventing the bottom 12c of fore shell from opening a ring 19 of disengaging from the bottom 14c of back cover, this two and half shell is mated.In addition, upper end 12b and 14b is retrained by by a component 16, and wherein, hook 16b engages with pin 12a, simultaneously a pair left and right component 16a in the circumferential buckle support described upper end 12b and 14b.Be produced on the existence of the upper end of housing and the screw thread of bottom, allow this device to be fastened to the suitable sleeve being fixed on outside suspension element (such as ceiling), or be even fastened to specific assembly, such as cable covers sheath.
Back cover 14 is provided with an annular protrusion in center, have two grooves 18, is manufactured with a dead hole in its lower process part, and it correspondingly has the cannelure that is used as cable passage.Abutted to described groove, a deflection pin 11 is inserted into described dead hole, and guide to described groove, the part of cable 50 from device 10 out.In intermediate projections, be supported with a torsional band spring 20, it is obtained by the mode that screw winding metal tape in assembled configuration is such, and described band has a short middle straight portion 24, and after the winding of a predetermined quantity, terminate with a bending end 22.By a stop pin 30, spring 20 is fixed and is connected to the center projections of back cover, and described stop pin 30 has the first end being provided with diameter grooving, and this diameter grooving forms a pair finger (fingers) 32 at described first end.Middle straight portion 24 is inserted into the grooving of stop pin 30, and its finger 32 snap into engagement is in the groove 18 of the projection of shell 14.Still with reference to Fig. 2, demonstrate cable 50 and be wound spool thereon, it comprises two independently parts, i.e. drum 40 and flange 60, and they are mechanically assembled and may be soldered, such as, pass through ultrasonic wave.Flange 42 after drum 40 has one, it is provided with at least one almost radial slot mouth 44, and one end 54 of cable 50 is fastened onto wherein, such as, by a simple knot.In front side, drum 40 is provided with 4 juts 46, arranges symmetrically relative to its longitudinal axis, each jut has a groove 48, and it has the shape of dovetail in this preferred embodiment.In each jut 46 and eminence same with groove 48, be provided with the finger 47 (Fig. 6) of one, it is after drum 40 is coupled with flange 60, is mechanically out of shape by cold or hot operation, thus a fixing constraint is formed to the Axial creep of these parts, avoid them mutually to extract out.In the centre position relative to jut 46, a through hole is fabricated on drum 40, and the second end of size and spring lock pin 30 matches.This will better illustrate hereinafter and describe, and drum 40 has a back seat 45, and torsionspring 20 is positioned this.On the flange 60 of spool, four dovetail members 66 are made integratedly, with axially symmetrical mode arrangement, and are suitable for the dovetail groove 48 mating drum 40.In addition, near each dovetail members 66, about the tie point with flange 60, one beak 64 flexibly swings, and described beak is rotated to a roughly radial direction and is suitable for the corresponding radial teeth of meshing gear 80.
Adjusting pin 70 has a tack 72, one for holding the groove of the head of pin 30 at first end; And at its other end, there is a screw thread 74 and for inserting the par with fixed head 17; The hole that described pin 70 passes drum 40 matches the end of pin 30, and this pin rotates around it.After packing ring 76 inserts, adjusting pin 70 is first inserted into the centre bore of gear 80, and gear 80 is provided with front flange 82, is then inserted into the centre bore of plate 17, and plate 17 is preferably made of metal.Then the end of thread 74 of pin 70 from the centre bore of fore shell 12 out, after second packing ring inserts, is engaged to band wing nut 15.More particularly, beak 64 is provided with the end 64a that is suitable for the tooth of meshing gear 80, and in this position, the undercut portions 64b of beak 64 is against the sidewall of jut 46.The operation of this connection to equipment provides Rigidity and strength, because the load being applied to end 64a is passed and is dispersed in more wide surface, as the surface of the sidewall of jut.
In figure 3, the spool describing shown suspension and arrangement for adjusting height 10 is inserted into the corresponding dovetail groove 48 of drum 40.Cable 50 is around reel wound.Identical combination is shown in the diagram, so that during the associated chamber 45 that torsionspring 20 is contained in drum 40 is shown better and by the end lock of stop pin 30 from rear side.
From the detailed description of device of the present invention, its running can be understood, wherein, in the counter clockwise direction of described spool rotates, relevant with engaging of gear 80 to it, and the coiling direction of cable 50 on spool is chosen such that the extraction of cable 50 corresponds to the anticlockwise rotation of described cable; In other words, cable 50 corresponds to the engagement of ratchet mechanism (being made up of gear 80 and beak 64) from the extraction device 10.In this obviously, tighten band wing nut 15, cause metallic plate 17 and packing ring 76 to compress the flange 82 of gear 80, result in one increases resistance to cable 50 from the rotation of spool 40 unwinding, thus allows this mechanism's Supporting connectivity to the different load of the material on it.In contrast, even when be with wing nut 15 maximum tighten, hawser 50 is always possible to returning of suspension arrangement, because at the clockwise direction of rotation, tooth 64 slides in the respective teeth of gear 80, causes spring freely to recoil cable and without friction.Therefore, by simple manual movement up or down, cable or unwinding support loading quality, or freely recoil, accurately stop at its d/d position.Also it is apparent that device of the present invention 10 can be used in reverse order, namely use hook 16 for the suspension of related item (lamp), and the end of cable 50 is used for device to be fixed to an external support component (as ceiling).
Should be noted that, according to many alternate embodiments of suspension of the present invention and arrangement for adjusting height, the basis of above preferred embodiment can draw, the described modifications and variations substituting related forms, material and the size comprising one or more assembly, but all such modifications and change fall in the scope of the present invention of appended claim restriction.
