The present invention is described in detail below in conjunction with drawings and Examples.
As shown in Figures 2 and 3, the preferred embodiment of pet rope pulling device of the present invention comprises a housing 10, a brake unit 20, a driver element 30, a clip unit 40 and a positioning unit 50.
This housing 10 is the hollow shelly, and have a perisporium 12 that can define a space 11 and one can be for the handle 13 that grips, this perisporium 12 offers an opening 121 that can be communicated to this space 11.This housing 10 also has a fixed block 15 that block 14 and that should opening 121 is positioned at these block 14 1 sides.
This brake unit 20 has an axle and is located at braked wheel 21, a stay cord 22 that is linked to this braked wheel 21 and a spring element 23 in the space 11 of this housing 10.This braked wheel 21 has the unidirectional latch 211 that most rings are located at outer peripheral edges, described unidirectional latch 211 respectively has a guiding face 212 that is inclination and one in contrast to this guiding face 212 and corresponding radially stop surface 213, this braked wheel 21 can rotate towards a first direction I, at this moment, described guiding face 212 is met to this first direction I and is rotated, this braked wheel 21 also can rotate towards a second direction II, and at this moment, described stop surface 213 is met to this second direction II and rotated.The spring element 23 of present embodiment is snail shape spring, and be attached between this braked wheel 21 and this housing 10, its elastic force can make this braked wheel 21 rotate towards first direction I, and this stay cord 22 is furled in this braked wheel 21, when this stay cord 22 is pulled out towards these housing 10 outsides, can stopper this braked wheel 21 rotate towards second direction II, and this spring element 23 is put aside back release elastic force.
This driver element 30 has slide plate 31 and first elastic parts 32 in the opening 121 that can reciprocatingly slide and be installed in this housing 10.This slide plate 31 has an operative end 311 that is arranged on these housing 10 outsides, one and stretches drive end 312 and the elongated slot 313 between this operative end 311 and this drive end 312 that is located in this housing 10, this elongated slot 313 is along this slide plate 31 glide directions extension and sheathed for this block 14, this first elastic parts 32 is set in this elongated slot 313, and butted between this block 14 and this slide plate 31, and provide this slide plate 31 permanent maintenances towards this housing 10 outside mobile trend.
This clip unit 40 has an energy swing and is hubbed on cantilever 41 and second elastic parts 42 in this housing 10, this cantilever 41 has an articulated section 411 that is hubbed on this housing 10, first end 412 and a second end 413 of being located at these articulated section 411 opposite sides of being located at these articulated section 411 1 sides, this the second end 413 is provided with the pawl portion 414 of a described unidirectional latch 211 of correspondence, one in the inboard and stepped location division 415 of this pawl portion 414 and one between this location division 415 and this articulated section 411, wear groove 416, this second elastic parts 42 is butted between this first end 412 and this fixed block 15, and the elastic force perseverance of this second elastic parts 42 makes this pawl portion 414 keep the gesture of driving that breaks away from respect to described unidirectional latch 211.
This positioning unit 50 is lever-like and can rotates and be hubbed in this housing 10, and has pivot part 51 and promotion end 52 and a blocking end 53 that is arranged on these pivot part 51 opposite sides that is arranged on these pivot part 51 1 sides and is positioned at these housing 10 outsides that is hubbed on this housing 10, this blocking end 53 can inlay cards on the location division 415 of this clip unit 40, and make this pawl portion 414 keep producing blockings towards any unidirectional latch 211.
Again as shown in Figures 2 and 3, the reset condition that shows pet rope pulling device of the present invention, at this moment, the slide plate 31 of this drive unit 30 is subjected to the elastic force effect of this first elastic parts 32,312 of this drive end are a primary importance, the cantilever 41 of this clip unit 40 is also because be subjected to the effect of this second elastic parts 42, make this pawl portion 414 be positioned at one and break away from the disengaging configuration of described unidirectional latch 211, and the blocking end 53 of this positioning unit 50 stretch be located at this wear in the groove 416 and the position an off-position that is away from the location division 415 of this clip unit 40.At this moment, this braked wheel 21 is free shape, and this stay cord 22 can rotate towards second direction II by this braked wheel 21 of stopper when being drawn out, and when the tension force elimination of this stay cord 22, is subjected to the elastic force effect of this spring element 23, and this braked wheel 21 can rotate towards first direction I.
When desire control rope stretching length, as shown in Figure 4, the operator suppresses the operative end 311 of this slide plate 31, and make this drive end 312 move to a second place by primary importance, this clip unit 40 is subjected to 31 stoppers of this slide plate, this cantilever 41 is produced to pivot, impel this pawl portion 414 to produce blocking towards any unidirectional latch 211, that is to say, this pawl portion 414 is revolved by disengaging configuration and moves to a blocking position that is equipped in any stop surface 213, and makes this braked wheel 21 produce two-way stop.
Then, as Fig. 5 and shown in Figure 6, the operator promotes the promotion end 52 of this positioning unit 50 again, can make this blocking end 53 by an off-position (as shown in Figure 4) that is away from this location division 415, revolves to move to an inlay card in position processed, the top of this location division 415.At this moment, this stay cord 22 can not be drawn out, and this braked wheel 21 also can't rotate toward first direction I or second direction II, and is in the state of complete stop, then can control the stay cord 22 that is drawn out to these housing 10 outsides and have fixing length.
When the operator desires to adjust these stay cord 22 length again, only need again promotion end 52 with this positioning unit 50 toward oppositely promoting, and this blocking end 53 is revolved by position processed, top (as shown in Figure 5) move to off-position (as shown in Figure 4), and when loosening the press power to this operative end 311 again, utilize returning of this first elastic parts 32 to release elastic force, can make this drive end 312 move to primary importance by the second place, and the pawl portion 414 of this cantilever 41 also can revolve by the blocking position again and move to disengaging configuration, and returns back to Fig. 2 and state shown in Figure 3.
Therefore, pet rope pulling device of the present invention utilizes this this clip unit 40 of driver element 30 interlocks to produce disengaging or blocking with respect to this brake unit 20, and utilize this positioning unit 50 to make this clip unit 40 remain on the blocking position, then make this braked wheel 21 reach two-way stop, not only control rope stretching easily and receive rope length, overall structure is also quite simple.
