Abstract
A trolley case provided with shrinkable wheels comprises a case body, a draw bar, wheels and axles, wherein the wheels are arranged at two sides of the bottom of the case body; and the draw bar can be pulled out outward. The trolley case provided with contraction wheels is characterized in that a splicing bar is protruded at the bottom of the draw bar, and a spring is sheathed on the splicing bar; shrinkable axles are horizontally arranged at the bottom of the case body; the wheels are rotatably arranged at the outer side ends of the axles; and an insertion hole, a stop block and the spring are arranged on the wheels sequentially from outside to inside. By utilizing the trolley case provided with shrinkable wheels, the case body and the two wheels form a triangle when the wheels extends out, the trolley case provided with shrinkable wheels has good stability during the pulling process, and is not easy to swing. The trolley case provided with shrinkable wheels is more convenient and faster, and the safety is improved.
Description
Technical field:
The utility model relates to a kind of draw-bar box that shrinks wheel that has, and belongs to the case and bag technical field.
Background technology:
Along with the development of the vehicles, the chance that people travel outdoors significantly promotes, and draw-bar box is also along with demand occurs.Draw-bar box is a kind of chest with pull bar and roller; Let the user between advancing, need not heavy-laden baggage wieight, guiding and supporting and collecting for the convenience of the users again is so adopt the design of telescopic lever; It can receive widely-used when needed with in the pull bar retraction case because of it is easy to use.But draw-bar box generally has only two wheels, two wheels and casing in line, if draw too fast, casing is vacillated now to the left, now to the right easily, particularly on the road of injustice.
The utility model content:
The technical problem that the utility model will solve is: draw-bar box has only two wheels in the prior art, two wheels and casing in line, if draw too fast, casing is vacillated now to the left, now to the right easily.
For solving the problems of the technologies described above, the utility model provides a kind of draw-bar box that shrinks wheel that has, and concrete technical scheme is following:
A kind of draw-bar box that shrinks wheel that has is made up of casing, pull bar, wheel and wheel shaft, and said wheel is arranged on the two bottom sides of casing, and pull bar can outwards be pulled out, and it is characterized in that: the pull bar bottom is protruding with shank, is with spring on the shank; The wheel shaft that can stretch flatly is located at bottom half, and wheel can be arranged on the outboard end of wheel shaft rotationally, and wheel shaft is provided with jack, limited block and spring from outside to inside successively.
Preferably, said pull bar is the two-segment type pull bar.
Preferably, in said bottom half center one fast pulley is arranged.
Preferably, said pull bar is the steel alloy material.
The beneficial effect of the utility model is: utilize the described draw-bar box that shrinks wheel that has of the utility model, when wheel stretches out, form triangle between casing and the two-wheeled, have good stability during the journey what draw, right pendulum is shaken on a difficult left side.More convenient, improve security.

The specific embodiment:
Combine accompanying drawing that the utility model is done further explanation at present.
Shown in Fig. 1-7, a kind of draw-bar box that shrinks wheel that has is made up of casing 1, pull bar 2, wheel 3 and wheel shaft 4; Said wheel 3 is arranged on the two bottom sides of casing 1; Pull bar 2 can outwards be pulled out, and it is characterized in that: the bottom of pull bar 2 is protruding with shank 5, is with spring 6 on the shank 5; Wheel shaft 4 can stretch, and flatly is arranged in the bottom of casing 1, and wheel 3 can be arranged on the outboard end of wheel shaft 4 rotationally, and wheel shaft 4 is provided with jack 7, limited block 8 and spring 9 from outside to inside successively.When pull bar 2 is not pulled out, the jack 7 that shank 5 inserts on the wheel shaft 4, wheel 3 applying casings 1 are not pulled out; When pull bar 2 was pulled out, shank 5 was upwards pulled out from the jack 7 of wheel shaft 4, and spring 9 live axles 4 on the wheel shaft 4 are protruding, thus wheel 3 pull out to both sides, behind the wheel shaft 4 protruding certain distances, limited block 8 blocks casing 1, wheel shaft 4 no longer stretches out.Said pull bar 2 can be that the two-segment type pull bar is to regulate height.Can be provided with a fast pulley and other two wheels supporting box together in center, said casing 1 bottom.Said pull bar is the steel alloy material.Utilize the described draw-bar box that shrinks wheel that has of the utility model, when wheel stretches out, form triangle between casing and the two-wheeled, have good stability during the journey what draw, right pendulum is shaken on a difficult left side.
