See also Fig. 1 to Fig. 4, this rotating disk 20, be arranged in this housing 10, be formed with on the outer peripheral face of this rotating disk 20 one around the depression around rope district 21, on one lateral surface of this rotating disk 20 along same axle center around being formed with some locating dowel 22(that arrange according to preset space length in present embodiment, the quantity of this locating dowel is more than three), then have a cable wire head holddown groove 23 and on another lateral surface of this rotating disk 20 and be communicated with this cable wire head holddown groove 23 and this connectivity slot 24 around rope district 21, and the groove width of this cable wire head holddown groove 23 and groove depth are all greater than this connectivity slot 24.
See also Fig. 1 to Fig. 4, this brake block 30, have some locating hole 31(that center on along same axle center and arrange according to preset space length in present embodiment, the quantity of this locating hole is more than three holes), to be pegged graft for the locating dowel 22 of this rotating disk 20 respectively by these a plurality of locating holes 31, make this brake block 30 be positioned at this housing 10, and be fixed on the side of this rotating disk 20.
See also Fig. 1 to Fig. 4, this brakes platen 40, is arranged in this housing 10, and amplexiforms with one lateral surface and this brake block 30.
See also Fig. 1 to Fig. 4, these a plurality of brake units 50 are positioned at this housing 10, and these a plurality of brake units 50 are arranged at respectively on this braking platen 40 with the angle at a distance of 120 degree.This each brake unit 50 has respectively a block 51 and a spring 52, one end of this block 51 is articulated on this braking platen 40, the two ends of this spring 52 then are connected on this block 51 and this braking platen 40, to be produced the pulling force of this block 51 of pulling by this spring 52.
See also Fig. 1 to Fig. 4, this axostylus axostyle 60 passes this housing 10 successively, and affixed with this rotating disk 20 and this braking platen 40, make this rotating disk 20 can be take this axostylus axostyle 60 as the axle center in these housing 10 interior rotations.
See also Fig. 1 to Fig. 4, this wind spring 70 is arranged in this housing 10, and an outer end of this wind spring 70 is fixed on the second case 12 of this housing 10, the inner of this wind spring 70 then is fixed on this axostylus axostyle 60, and enable pass is crossed the pre-power that 70 pairs of these axostylus axostyles 60 of this wind spring and this rotating disk 20 are bestowed a rollback.
See also Fig. 1 to Fig. 5, this cable wire unit 80, has a cable wire 81, the one cable wire head 82 and that is connected in these cable wire 81 1 ends is connected in the fastener 83 of these cable wire 81 other ends, this cable wire head 82 is limited in the cable wire head holddown groove 23 of this rotating disk 20,81 of this cable wires pass the connectivity slot 24 of this rotating disk 20 and be wound in constantly this rotating disk 20 after in the rope district 21, be piercing in the other end again that the perforation 13 of this housing 10 is outer to be connected with this fastener 83, to be buckled on user's the body by this fastener 83, this housing 10 then is buckled on the fixture (not shown) by another fastener (not shown).
See also Fig. 1 to Fig. 4, this elasticity pushing tow unit 90 has a goring push spring 91 and a briquetting 92; This goring push spring 91 is placed on the cable wire 81 that passes outside this housing 10, and is connected with this housing 10 with the one end, and 92 of this briquettings are connected on the other end of this goring push spring 91.
Thus, when this cable wire 81 is pulled out lentamente, because the rotating speed of this rotating disk 20 is unhappy, and can not cause excessive rocking to rotating disk 20, therefore the block 51 that is hubbed on this rotating disk 20 still can be held by the pulling force of this spring 52, and can not produced with the breaker slot 14 of this housing 10, this block 51 interferes, and the smoothness that can keep this cable wire 81 to pull out.
When this cable wire 81 is pulled out or this rotating disk 20 when being subject to larger rocking rapidly, the centrifugal force that this rotating disk 20 produces or its rock the active force that produces, can cause the pulling force of these block 51 these springs 52 of opposing, be connected on this breaker slot 14 and outwards throw away, make to produce between the cell wall of this block 51 and this breaker slot 14 and interfere, and provide the active force that slows down and stop operating by the frictional force of 40 of this brake block 30 and rotating disk 20 and this braking platens, avoiding this cable wire 81 to be continued to be drawn out, and can prevent the accident that the operating personnel falls.
Therefore, pegged graft with the locating dowel 22 of rotating disk 20 because brake block 30 of the present utility model has three holes above locating hole 31, and can be increased the binding effect of rotating disk 20 and 30 of brake blocks, with the situation of avoiding producing slip between the two or getting loose.
In addition, owing to the utlity model has three groups of above brake units 50, therefore can increase by 10 braking effects that produce when interfering of brake unit 50 and housing, so that the stability of braking is better.
Moreover, because the cable wire head 82 of this cable wire unit 80 is arranged in the cable wire head holddown groove 23 of rotating disk, and the groove width of this cable wire head holddown groove 23 and groove depth are all greater than groove width and the groove depth of this connectivity slot 24, therefore be fixed in this cable wire head holddown groove 23 when interior when this cable wire head 82, the binding effect of 20 of this cable wire unit 80 and this rotating disks can be strengthened, and the stressed of cable wire unit can be effectively promoted.
Secondly, when wish allows the block 51 of this brake unit 50 break away from the breaker slot 14 of these housings 10, this cable wire unit 80 can be passed in the housing 10 and is reached.When if this cable wire unit 80 is by the state of rolling (as shown in Figure 6), then can pass first the briquetting 92 of this elasticity pushing tow unit 90, make by this briquetting 92 and be pressed against on this goring push spring 91, and make this goring push spring 91 compressed, and allow cable wire 81 expose slightly a segment length (as shown in Figure 7), then just fastener 83 and the cable wire 81 of this cable wire unit 80 can be pushed toward housing 10 directions, enable to rotate a little this rotating disk 20, and allow this brake unit 50 break away from this breaker slot 14,10 of this brake unit 50 and this housings are no longer produced interfere, used and can successfully pull out this cable wire 81.
Above institute takes off, it only is preferred embodiment provided by the utility model, be not the scope that limits the utility model embodiment, the equalization that all related art techniques persons in the art do according to the utility model changes, and all should belong to the scope that the utility model is contained.
