In figure: chassis 1, chute 101, wheel union lever 2, wheel 3, wheel seat 31, dog wedge 32, compressing tablet 33, handle connecting rod 4, hand handle 5, bearing support 6, leading screw 7, spring 8, handle 9, pin-and-hole 91, bearing pin 92, rolling bearing 10, carrier table 11, baffle plate 111, the first pole 12, hinged bar 13,2nd pole 14, hinge seat 15, push rod 16.

Embodiment

In this example, the lower right in Fig. 1 is front end.

As in Fig. 1 ~ 3, a kind of collapsible formula lifting carrying dolly, comprise chassis 1, wheel 3 is installed bottom chassis 1, the front end of chassis 1 is provided with handle 9, and chassis 1 is provided with lifting device, and lifting device is provided with carrier table 11, preferably it is provided with baffle plate 111 in the rear end of carrier table 11, avoids parcel to drop. As, in Fig. 1, described handle 9 is connected with the front end of chassis 1 by bearing pin 92, is also provided with spring 8 between bearing pin 92 and chassis 1. This connection structure is identical with existing plate pusher, and handle 9 can fold. When lifting device is fallen, state time folding is as shown in Figure 2, identical with ordinary flat go-cart, is convenient to carry. State during use is as shown in Figure 3. When lifting device rises, it is convenient to the carrying of heavier parcel, it may also be useful to state is as shown in fig. 1.

Preferred scheme is as shown in fig. 1, in described lifting device, " X " shape frame rear end is hinged with chassis 1 and carrier table 11 respectively, the front end of " X " shape frame is provided with rolling bearing 10, being provided with chute 101 inside chassis 1 and carrier table 11 side, rolling bearing 10 slides in chute 101;

The bottom front of " X " shape frame also with push rod 16 pivot joint, leading screw 7 is bearing in the front end of chassis 1 by bearing support 6, is provided with screw on push rod 16, and screw is threaded with leading screw 7. By the rotation of leading screw, drive push rod 16 to move forward and backward, thus drive lifting device to realize elevating function. In leading screw 7 rotary course, owing to push rod 16 adopts articulated manner to be connected with the bottom front of " X " shape frame, namely push rod 16 along with the rotation of leading screw 7, can rotate taking the axis of push rod 16 as axle center thereupon, leading screw 7 can not be caused interference.

As, in Fig. 1, being provided with hand handle 5 or drive-motor in the front end of leading screw 7. The scheme of drive-motor is adopted to be conducive to realizing fast lifting, it is to increase working efficiency, drive-motor is by the battery power being arranged on chassis 1.

In described " X " shape frame, the first pole 12 and the 2nd pole 14 are hinged by hinged bar 13 in the position at middle part. As shown in fig. 1 in preferred scheme, being installed with wheel union lever 2 bottom chassis 1, wheel 3 is socketed in wheel union lever 2 by wheel seat 31, and can slide along wheel union lever 2, is provided with locking gear on wheel seat 31. Thus structure, as shown in Figure 4, it is possible to folded to centre by wheel 3, reduces volume further, is convenient to carry, and is also convenient under oblique pull state to operate simultaneously. Under oblique pull state, the wheel 3 being positioned at rear end also moves to the rear end of chassis 1 as far as possible. So that having a down dip angle more greatly in oblique pull state, operate more convenient.

In optional scheme, described locking gear is screw.

For ease of quick adjustment wheel seat 31 or by wheel seat 31 fold inward. Another optional scheme is as, in Fig. 5 ~ 7, described locking gear is the dog wedge 32 that cross section becomes arc, and dog wedge 32 is between the through-hole wall and wheel union lever 2 of wheel seat 31. When needing mobile or folding wheel seat 31, take off dog wedge 32, move or fold after putting in place, the lower dog wedge 32 of pressure, make to lock between the through-hole wall of wheel seat 31 and wheel union lever 2.

In preferred scheme, the outer end of dog wedge 32 is connected with one end of compressing tablet 33, and the other end of compressing tablet 33 is connected with wheel seat 31, and when dog wedge 32 wedging wheel union lever 2, compressing tablet 33 one-tenth bends state. Thus structure, when taking out dog wedge 32, only need to hold with a firm grip compressing tablet 33 and wheel seat 31, making compressing tablet 33 be tending towards stretching, compressing tablet 33 ejects in the through hole of wheel seat 31 by dog wedge 32, thus unclamps dog wedge 32 fast, due to the limited length of compressing tablet 33, dog wedge 32 can not be deviate from completely in through hole, thus is convenient to quick compression, also avoids dog wedge 32 to lose.

As, in Fig. 4, during oblique pull state, optional scheme is that lifting device is in folded state, described handle 9 directly or is socketed by sleeve pipe with wheel union lever 2, and locks with bearing pin 92;

The handle 9 that another optional scheme is described is socketed with the handle connecting rod 4 being fixedly mounted on chassis 1, and locks with bearing pin 92.

The multiple functions such as the utility model can realize transporting, lifting, folding and oblique pull, reduce labour intensity, it is to increase working efficiency, and cost increases few. The lightweight service requirements of logistics transport field can be met, the conveying of such as equipment or household electrical appliances. It is particularly suited for along with deliver goods car, by the transport that parcel is transported to client family this segment distance from deliver goods car.

The above embodiments are only optimal technical scheme of the present utility model, and should not be considered as restriction of the present utility model, and the embodiment in the application and the feature in embodiment be not when conflicting, it is possible to arbitrary combination mutually. The technical scheme that protection domain of the present utility model should be recorded with claim, the equivalent alternative comprising technology feature in the technical scheme of claim record is protection domain. Namely the equivalent replacement within the scope of this improves, also within protection domain of the present utility model.
