Description
Technical field
The technical field that the present invention relates to bundle, particularly a kind of take-up safety device of hand controller.
Background technology
Known hand controller (or claim strainer) is common in the place of circulation of commodities, can be with the Goods binding in heaps of vehicle carrying together, avoid the In transit ground that is scattered, and prevent that commodity are impaired.
The structure of hand controller is quite simple.For example Fig. 1 inserts a tape feed roller 12 between a pedestal 10 and one handle 11, and the three is articulated by an axle 13.Pedestal 10 sets firmly a bar 14, is enough to pass a tackline 15 and a rolled-up stock 16, and rolled-up stock 16 is tactile mutually with each tooth 17 of tape feed roller 12 circumference along with elastic force.Pedestal 10 marginal rises one protrusion 18, one holding piece 19 that is hubbed at handle 11 is caused living resistancing action, stop each tooth 17 of holding piece 19 contact tape feed rollers 12 circumference, allow handle 11 keep the state of close pedestal 10, pushed open one and prevented part 23, make the rotation of tape feed roller 12 no longer be subject to preventing part 23 to restrain.Tape feed roller 12 twines a long rope 20, long rope 20 is bestowed external force 21 and pulled out toward pedestal 10 outsides, related tape feed roller 12 rotates relative to pedestal 10 according to the direction of arrow, make each tooth 17 push respectively rolled-up stock 16 open and send continuous " noise made in coughing or vomiting " sound, drive simultaneously the elastic force of a wind spring (accompanying drawing is not painted) savings reinstatement.
The take-up of this hand controller has automatically available with manual two kinds of patterns.Automatic mode as shown in Figure 2,22 pairs of holding pieces of hollow-out parts, the 19 1 end application of forces from handle 11 cause holding piece 19 just like seesaw starts the other end, and related rolled-up stock 16 is away from each tooth 17 of tape feed roller 12 circumference.This moment, tape feed roller 12 is freely, by the elastic force of wind spring, rotates relative to pedestal 10 according to the direction of arrow, regains fast long rope 20.
Manual mode shown in Figure 3 and for example, holding piece 19 is crossed the protrusion 18 at pedestal 10 edges, and then blocks the arbitrary tooth 17 of tape feed roller 12 circumference.Pull handle 11 relative pedestals 10 and swing, drive tape feed roller 12 and rotate relative to pedestal 10 according to the direction of arrow, be equivalent to the amplitude of oscillation of 1～4 tooth 17, regain gradually long rope 20.Then, handle 11 is got back to the position near protrusion 18, continues crank motion according to the double-head arrow direction, until long rope 20 is finished the take-up action.
But this hand controller only has two kinds of take-up patterns, and the operation that is available for users to select is few.Especially, the automatic band-retracting pattern discharges the process of wind spring, can be fast and unhinderedly regain long rope, allow rope head (or title coupler body) retract according to inertia and cause living jump phenomena, relatively increase the operator or arround personnel's accidental injury rate.
Therefore, how to reduce the accidental injury rate of automatic band-retracting, increase simultaneously the take-up pattern, just become the problem that the present invention needs to be resolved hurrily.
Summary of the invention
In view of this, the problem of inventor's further investigated prior art relies on the experience of being engaged in for many years research and development and the manufacturing of related industry, actively seeks the road that solves, finally successfully develops a kind of take-up safety device of hand controller, to improve the problem of prior art.
Main purpose of the present invention is: adopt gradation take-up means, discharge one by one the Ships Turning Ability elastic force of take-up, reduce the hand controller automatic band-retracting to the operator or arround personnel's accidental injury rate.
Secondary objective of the present invention is: the take-up pattern that increases hand controller.
Because of reaching of above-mentioned purpose, the invention provides a kind of take-up safety device of hand controller, by a mandrel one pedestal and one handle are articulated, mandrel links a tape feed roller and a wind spring, furls a long rope at tape feed roller.This pedestal has the holding piece of a tackline and an Elastic Contact tape feed roller, is provided with one in susceptor edges and discharges take-up district and a tension operational zone.The cam edge of holding piece is backed out in this handle periphery formation one, and have a hollow-out parts and an elasticity and be articulated in handle and the local rolled-up stock that is exposed to hollow-out parts, this rolled-up stock is subject to and discharges the take-up district, can stop tape feed roller to furl long rope, but can be along with long rope to be pulled out and is rotated, related wind spring is put aside the kinetic energy that resets; This rolled-up stock is subject to the tension operational zone, along with handle swing order about tape feed roller manual furl long rope.
In more detail, hand controller of the present invention is articulated a pedestal and one handle by a mandrel, mandrel links a tape feed roller and a wind spring, tape feed roller has two fluted discs and a spool, this spool is linked between two fluted discs, insert a long rope that is enclosed within mandrel in the spool, long Suo Qiyu part can be wrapped in the spool outside.This pedestal both sides bends a riser separately, each riser edge has a protrusion and a termination section, protrusion caves on one side and one discharges the take-up district, be absorbed in the tension operational zone of a restriction handle amplitude of fluctuation between protrusion another side and the termination section, and between two risers, arrange a reciprocating holding piece and a bar, overlapping a tackline on the bar.This handle has a hollow-out parts, the handle both sides bend respectively one side by side in the bluff bit of riser, each bluff bit periphery forms one along with handle swings the cam edge that determines that holding piece is backed out, and pivot joint one has elastomeric rolled-up stock between two bluff bits, this rolled-up stock one end is exposed to the hollow-out parts of handle, the other end is subject to the tension operational zone, along with handle swing order about tape feed roller manual furl long rope, also can be release take-up district limits, stop tape feed roller to furl long rope, but can be along with long rope to be pulled out and is rotated, related wind spring is put aside the required kinetic energy that resets.
Wherein, this rolled-up stock is located outstanding required protuberance in the face of tape feed roller (or fluted disc).The cam edge of this handle (or bluff bit) swells a stop part, and this stop part is along with handle offsets with the holding piece of Elastic Contact tape feed roller in the swing that discharges the take-up district.
So, handle can discharge the swing of take-up district, related rolled-up stock jumpily contacts tape feed roller (or fluted disc), causes wind spring to drive tape feed roller (or spool) rotation and the local long rope of automatic rolling according to moment of torsion, until rotation function is pressed the part counteracting and stops operating; Hollow-out parts by handle is pressed rolled-up stock, removes the resistance of tape feed roller (or fluted disc) and the moment of torsion of release wind spring remnants, drives tape feed roller (or spool) and collects remaining long rope.
Such hand controller possesses following three kinds of take-up patterns:
[manual mode]

The specific embodiment
Seeing also the hand controller 30 of Fig. 4, Fig. 5, is to be articulated with tape feed roller 60 by pedestal 40, handle 50, determines the straight length of tackline 31 and long rope 32.These tacklines 31 link respectively a coupler body 33 with long rope 32 external ends, are enough to hook on the vehicle or the fixed object, shorten two coupler bodies 33 distance to each other by handle 50, finish the purpose of restraint of loads, prevent that commodity are impaired.
These pedestal 40 both sides are bent with separately and arrange elastomeric holding piece 42 and bar 43 between riser 41, two risers 41, and a riser 41 outsides therein set firmly a take-up device.Each riser 41 marginal rise protrusions 44 and termination sections 45 are to discharge take-up district 46 at protrusion 44 on one side, and protrusion 44 another sides to termination section 45 is absorbed in and strains operational zone 47.The riser 41 that correspondence is inserted in holding piece 42 both sides runs through in the rectangular opening 48, moves reciprocatingly along hole wall according to elastic force.This bar 43 is anchored on riser 41 1 ends, is overlapping tackline 31 on the bar 43.
Aforementioned take-up device is that a wind spring 36 warps are inserted a housing 34 compositions.These wind spring 36 1 ends are fixed on housing 34 inwalls and irremovable, and the other end links to each other with mandrel 35.Because mandrel 35 possesses synchronous start relation with tape feed roller 60, so wind spring 36 can be realized the effect of the long rope 32 of tape feed roller 60 the automatic recoveries.
These handle 50 middle parts form hollow-out parts 51, and there is bluff bit 52 handle 50 both sides, and each bluff bit 52 in riser 41 inner faces of correspondence, is articulated by mandrel 35 together with tape feed roller 60 side by side.Articulate elastomeric rolled-up stock 53 between two bluff bits 52, each bluff bit 52 periphery forms cam edge 54, and 35 distance is different in size from cam edge 54 to mandrel, and at cam edge 54 protuberance stop parts 55.This rolled-up stock 53 is similar to T shape sheet, and vertically section 57 is exposed to hollow-out parts 51 belows of handle 50, and traversing section 56 is crossed over the release take-up district 46 of two risers 41, and gives prominence to two protuberances 58 at traversing section 56 in the face of the position of tape feed roller 60.
This tape feed roller 60 is to link at spool 61 two ends fluted disc 62 is arranged.Spool 61 is enclosed within mandrel 35 outsides, in order to twine local long rope 32.A hole 63 is run through in fluted disc 62 central authorities, and hole wall is enclosed within mandrel 35 outsides, supports tape feed roller 60 around mandrel 35 rotations.The some teeth 64 of fluted disc 62 peripheral circular rows, each tooth 64 has a radial face 65 and a curved surface 66.
Because rolled-up stock 53 is subject to protrusion 44, can be the crank motion of set scope across discharging take-up district 46, so handle 50 is backed out along the guiding of rectangular opening 48 with the cam edge 54 push card valve parts 42 of bluff bit 52, until stop part 55 props up holding piece 42 backward.This rolled-up stock 53 across on discharge take-up district 46, in the time of away from protrusion 44, relies on protuberance 58 to stop the strength of fluted disc 62 with traversing section 56, makes tape feed roller 60 keep quiescence together with wind spring 36.This moment, long rope 32 is stressed pulls out both measured lengths along arrow, drives tape feed roller 60 synchronous rotaries, the required elastic force of related wind spring 36 savings reinstatements.
Among Fig. 6, handle 50 relative pedestals 40 swing, until traversing section 56 props up protrusion 44 along discharging take-up district 46, make handle 50 swing forward and backward formation one drop S.Simultaneously, displacement is equivalent to one or above tooth pitch to rolled-up stock 53, related protuberance 58 synchronizing movings that fall between adjacent two teeth 64 along with handle 50 swings.This moment, fluted disc 62 allows the curved surface 66 of tooth 64 be displaced to both allocations followed by protuberance 58 under the torsional interaction of wind spring, does not expose to each other slit (or slightly distance), naturally is not enough to push open rolled-up stock 53.Add stop part 55 and leave holding piece 42 along with handle 50 swings, make the cam edge 54 of bluff bit 52 no longer prevent holding piece 42, cause holding piece 42 to touch fluted disc 62 tooth 64 of correspondence on every side according to elastic force, even block the radial face 65 of tooth 64, prevention tape feed roller 60 is driven by long rope 32 and rotates.In other words, tape feed roller 60 is hampered by holding piece 42 and protuberance 58, keeps actionless state.
In order to help the reader to understand following continuous action, compile A tooth, B tooth, C tooth according to English alphabet ....
Can find that from Fig. 7 tape feed roller 60 touches protuberance 58 with the curved surface 66 of C tooth, chase rolled-up stock 53 to move on to both allocation and transfixion with following in sb's footsteps.
In Fig. 8, handle 50 is stressed to be swung to pedestal, and related protuberance 58 is along the curved surface 66 of C tooth, and slippage is to the crown position that radial face 65 has a common boundary, and causes rolled-up stock 53 to start according to the direction of arrow.Though this protuberance 58 keeps friction law with curved surface 66, be not enough to drive tape feed roller 60 (or fluted disc 62) according to the rotation of drawing counterclockwise, can only be open along the radian of curved surface 66.
Then see Fig. 9, handle 50 amplitudes of oscillation continue to increase, and protuberance 58 separates with the C tooth, cause rolled-up stock 53 forfeiture to the resistancing action of fluted disc 62, add holding piece 42 such as Contact Tooth 64 no longer as Fig. 5, cause tape feed roller 60 to be in the non-resistance state.Simultaneously, the moment of torsion rapid reaction of wind spring is to tape feed roller 60, and band active toothed disk 62 rotations one angle theta makes B tooth bump protuberance 58, makes rolled-up stock 53 be open according to the direction of arrow.Even rolled-up stock 53, is also returned back to the A tooth of equal angular according to the elastic returning original state and is pushed open ... go round and begin again, the some number of turns of fluted disc 62 rotation, with around each tooth 64 push continuously rolled-up stock 53 open, relatively furl local long rope.This rolled-up stock 53 jumpily contacts tape feed roller 60, offsets gradually its rotation function, until mutually anti-answer state of equilibrium each other just can allow protuberance 58 again fall between two adjacent teeth 64, stops tape feed roller 60 rotations and stop long rope to furl action.
It should be noted that long rope pulls out length the more, the torque rating of wind spring accumulation is just larger, and tape feed roller 60 rotates the number of turns to be increased relatively, and long rope automatic rolling length is naturally just many.Opposite, it is few that long rope is pulled out length, and tape feed roller 60 rotating speeds are slower.This moment, can consider to adopt following step or action, furl the remaining length of long rope.
Among Figure 10, by the hollow-out parts 51 of handle 50, press rolled-up stock 53 vertical section 57, traversing section 56 is upwarped, cause protuberance 58 to leave the curved surface 66 of the tooth 64 of fluted disc 62 correspondences.Lose the wind spring that containing strength is restrained, rely on residual moment of torsion, drive spool 61 and collect remaining long rope 32 according to arrow.So, just can not allow coupler body 33 retract according to inertia and cause living jump phenomena, relatively protect the operator or arround personnel's personal safety.
Then see Figure 11, Figure 12, show that handle 50 swings the manual mode of take-up.Rolled-up stock 53 among the figure is crossed protrusion 44 and across on tension operational zone 47, is allowed handle 50 be confined to carry out reciprocating type swing between protrusion 44 and the termination section 45 with traversing section 56.Traversing section 56 withstands radial face 65, drives tape feed roller 60 and rotates a tooth 64 or above amplitude, furls lentamente the long rope 32 that is drawn out.
According to the structure of above-mentioned hand controller, the following example of deriving.Figure 13～rolled-up stock 53 shown in Figure 15 for example, be different from previous embodiment locate be: traversing section 56 does not have protuberance.
During use, the curved surface 66 of traversing section 56 compacting C teeth makes tape feed roller 60 keep the transfixion state.When handle 50 stressed swings, related traversing section 56 arrives the crown position along 66 slippages of C tooth curved surface, and pushes rolled-up stock 53 open according to the direction of arrow.Continue to press lower handle 50, make traversing section 56 leave the C tooth, cause tape feed roller 60 twirl, clash into continuously traversing section 56 with each tooth 64 around the fluted disc 62, relatively furl local long rope, until tape feed roller 60 rotation functions are offset gradually by traversing section 56, just can stop the action that tape feed roller 60 furls long rope.
Above-described embodiment only is explanation the present invention, and is non-for limiting the present invention.The various variations that those skilled in the art derive from above-described embodiment, modification and application are all in category of the present invention.
