The utility model mainly is the draw-bar box hired car about a kind of tool rocker-arm expanding pulley, please cooperate referring to Fig. 1, by seeing among the figure, if trolley luggage car owner of the present utility model includes a casing 10 that can hold article, be provided with a framework 12 in casing 10 end faces, and be provided with two groups of parallel draw bars 14 that run through framework 12.Wherein, each pull bar 14 can be the body of rod of the single body of rod or several mutual sockets to be formed, and is provided with leader 16 in two pull bars, 14 tops again, is provided with a control knob 162 in handle 16, and the flexible and expansion of controlling pull bar 14 folds.
Be provided with an expanding pulley in casing 10 nearly each place, pull bar 14 bottoms again, and the structure of expanding pulley is to shown in Figure 4 as Fig. 2, it includes a hollow wheel seat 20 that is fixed on the casing 10, and on wheel seat 20, be formed with an opening, in wheel seat 20, be pivoted with a wheel carrier 30 relative again with wheel seat 20 openings.On the whole this wheel carrier 30 is the support body that a cross section is font bending, is pivoted with a wheel 32 on wheel carrier 30, is provided with a coupled frame 22 that can move relative to wheel seat 20 vertical lifts again in wheel seat 20.Wherein, coupled frame 22 includes the body of rod 222 that runs through perforation 202 on wheel seat 20 end faces, be provided with a shape support body 226 that is positioned at wheel seat 20 inside in the body of rod 222 bottoms, and make coupled frame 22 slightly be forked form, be pivoted with a rocking arm 23 respectively in the both sides of coupled frame 22 support bodys 222, each rocking arm 23 also is pivoted mutually with wheel carrier 30.In addition, in wheel seat 20, be provided with a directed seat 28, these orientation seat 28 horizontal-extendings are formed with the two trip sheets 282 relative with support body 226 both sides, then respectively are arranged with to be formed with one and can to penetrate wherein gathering sill 264 for coupled frame 22 support bodys 226 opposite sides on two trip sheets 262.So, can allow coupled frame 22 move relative to wheel seat 20 vertical lifts really, the unlikely phenomenon that when mobile, produces skew, rotation by placing restrictions on of gathering sill 264.
Again, the body of rod 222 ends that pass wheel seat 20 in coupled frame 22 are provided with a threaded portion 224, this threaded portion 224 can screw togather mutually with the connecting rod cap 24 of a tool screw 242, is arranged with the spring 26 that two ends are resisted against wheel seat 20 and connecting rod cap 24 respectively on the body of rod 222 in addition.In addition, in casing 10, be provided with a retaining pipe 40 simultaneously relative, respectively be inserted with a connecting rod 42, and the end in addition of connecting rod 42 is to be connected with connecting rod cap 24 in retaining pipe 40 two ends with two pull bars 14.Wherein, connecting rod 42 mainly be in up-and-down rod body two ends respectively horizontal-extending be formed with a junction 422 and 424, by two connecting portions 422,424 interconnect with retaining pipe 40 and connecting rod cap 24 respectively, can make retaining pipe 40 and connecting rod cap 24 mutual interlocks, and connecting portion 42 and retaining are managed 40 syndeton, mainly be on retaining pipe 40 and connecting portion 422, draw-in groove 402 to be set, 423, wherein the draw-in groove 423 on the connecting portion 422 can be a plurality of, penetrate and be equipped in the relative draw-in groove 402 of retaining pipe 40 and connecting portion 422 simultaneously with a jump ring 44 again, in 423, so that make connecting portion 422 affixed mutually with retaining pipe 40, and can adjust the block position of 40 of connecting rod 42 and retaining pipes by changing the draw-in groove 423 and jump ring 44 blocking mutually of diverse location on the connecting portion 422.
In addition, be provided with a horizontal connecting hole 244 in connecting rod cap 24, so that allow another connecting portion 424 of connecting rod 42 penetrate in the connecting hole 424,, so just can allow connecting rod cap 24 and retaining pipe 40 pass through to connect pull bar 42 and mutual interlock so that allow this connecting portion 424 interconnect with connecting rod cap 24.
Please cooperate referring to Fig. 2 to Fig. 4.When being retracted to pull bar 14 in the casing 10, retaining pipe 40 can be subjected to reclaiming compressing of pull bar 14 and relatively casing 10 move down, and by trace 42 drivening rod caps 24 and coupled frame 22 also with move down, and compress spring 26.At this moment, wheel carrier 30 can be subjected to pulling and supporting of rocking arm 23 and keep being retracted in the state of wheel seat 20 inside, and allows wheel 32 be contained in wheel seat 20 inside simultaneously to be the form that is hidden in the casing 10.So, just can avoid collection or when carrying wheel 32 broken, also can suitably dwindle the whole volume of draw-bar box hired car simultaneously, the convenience when increasing collection and carrying.
Please cooperate referring to Fig. 1,5,6.When desiring to tow this draw-bar box hired car, control knob 162 on the user elder generation squeeze grip 16, and upwards spur pull bar 14, make pull bar 14 relative casings 10 stretch out expansion, in order to user's gripping with tow pull bar 14 move up launch in, can allow retaining pipe 40 because of moving up of pull bar 14 loses the strength that compresses downwards, by this just can be by the recovery elastic force of spring 26, come ejection connecting rod cap 24 to move up, and drive coupled frame 22 simultaneously and retaining pipe 40 moves up.When coupled frame 22 moves up, can drive rocking arm 23 relatively rotates, be subjected to the placing restrictions on of directed seat 28 on gathering sill 284 because of coupled frame 22 this moment, only can be vertically and vertically move, so rocking arm 23 is when moving up with coupled frame 22, the other end can be released the openings of wheel seats 20 relatively with wheel carrier 30, and allow simultaneously wheel 32 expose outside wheel seat 20 outside, and make wheel 32 be positioned at the user mode of stretching out casing 10, allow the user can tow this draw-bar box hired car like a cork and advance.
And when the user regains pull bar 14, then can be because of the pushing and pressing of pull bar 14, and by keeping off the interlock of pipe 40, connecting rod 42 and connecting rod cap 24, allow coupled frame 22 move down, and drive rocking arm 23 and in wheel seat 20, relatively rotate, and wheel carrier 30 and wheel 32 are regained wheel seats 20 inboards, shown in Fig. 3,4, so can allow wheel 32 along with the expansion or the withdrawal of pull bar 14, and expose respectively or the casing 10 of withdrawing, cooperate the use of trunk cart.
In addition, please cooperate, be vertically arranged with a microscler slotted hole 142 respectively, and retaining pipe 40 is the slotted holes 142 that run through two pull bars 14 simultaneously in two pull bars, 14 positon of near bottom referring to Fig. 2,3,5.So, can launch or regain when mobile, allow pin 40 move relative to pull bar 14 along slotted hole 142 at pull bar 14, can be to guarantee that retaining manages 40 with pull bar 14 lifting moving, and make the control of wheel 32 more reliable.In addition, in casing 10, can be installed with a fixed head 50, on fixed head 50, then be provided with and to run through wherein locating hole 52 for pull bar 14 bottoms.So, by the restriction of locating hole 52, the stability in the time of can keeping pull bar 14 telescopic movings, and then make moving of retaining pipe 40 and expanding pulley more stable.
