Abstract
The utility model discloses a retractable-wheel draw bar box which comprises a box body and a draw bar and wheels connected on the box body, wherein the box body is provided with wheel grooves and a fixing frame, the wheels are connected with a wheel supporting arm via wheel shafts, the wheel supporting arm is connected on the fixing frame via a connecting shaft, the fixing frame is connected with a wheel stretching buckle, and the wheel grooves are connected with wheel retracting lock. The retractable wheels of the retractable-wheel draw bar box have simple structure, big wheels are adopted, and the box body is raised when the wheels stretch. Compared with the known small-wheel draw bar box, the retractable-wheel draw bar box has higher drawing comfort level when drawn on uneven and rough road surfaces, and the box body is easy to protect. Compared with the known big-wheel draw bar box, the stacking of the draw bar box can not be affected because the wheels can be retracted.
Description
Technical field
The utility model relates to a kind of draw-bar box, in particular to a kind of expanding pulley draw-bar box.
Background technology
The wheeled draw-bar box of prior art has the advantage of drawing row and the heap of case fortune of car, but usually with wheel do less, with favourable and heap fortune,, in roughness pavement and frustration, draw when capable owing to take turns lessly, promptly uncomfortable, also marginal security; Also have with wheel do bigger, improves and to draw capable comfort level, but because wheel is bigger, outstanding casing is more, then is unfavorable for heap fortune; Also have big of bull wheel is shunk in casing, but owing to draw when capable case overhead nearer, fragile casing.
The utility model content
The purpose of the utility model is to overcome the above problem that prior art exists, provide a kind of and conveniently draw row, improve draw capable comfort level, be convenient to stack storage, wheeled draw-bar box simple in structure.
For realizing above-mentioned technical purpose, reach above-mentioned technique effect, the utility model is realized through following technical scheme:
A kind of expanding pulley draw-bar box; Comprise casing, and be connected in pull bar and wheel on the said casing, said casing is provided with race and fixed mount; The said wheel through wheel shaft is connected with the wheel support arm; The said support arm of taking turns is connected in said fixed mount through connecting axle, and said fixed mount is connected with wheel and stretches out snap close, and said race is connected with the wheel withdrawal and ends button.
Further, said race is arranged at said bottom half both sides, and said fixed mount is fixed on the casing of said race one side.
Further, the said support arm of taking turns can be around said connecting axle rotation.
The beneficial effect of the utility model is:
The expanding pulley of expanding pulley draw-bar box is simple in structure, adopts bull wheel, and casing was raised when wheel stretched out, and more known steamboat formula draw-bar box especially draws row in roughness pavement and frustration, improved and drawn capable comfort level, is easy to protect casing; More known big wheeled draw-bar box is not because wheel can be influenced the stacking of draw-bar box by indentation.
Above-mentioned explanation only is the general introduction of the utility model technical scheme, in order more to know the technological means of understanding the utility model, and can implement according to the content of specification, below with the preferred embodiment of the utility model and conjunction with figs. specify as after.The specific embodiment of the utility model is provided by following examples and accompanying drawing thereof in detail.

The specific embodiment
Below with reference to accompanying drawing and combine embodiment, specify the utility model.
With reference to Fig. 1, Fig. 2, shown in Figure 4, a kind of expanding pulley draw-bar box comprises casing 2; And be connected in the pull bar 1 on the said casing 2 and take turns 4; Said casing 2 is provided with race 3 and fixed mount 8, said take turns 4 through wheel shaft 5 be connected with the wheel support arm 6, the said support arm 6 of taking turns is connected in said fixed mount 8 through connecting axle 7; Said fixed mount 8 is connected with wheel and stretches out snap close 9, and said race 3 is connected with the wheel withdrawal and only detains 10.
Further, said race 3 is arranged at said casing 2 two bottom sides, and said fixed mount 8 is fixed on the casing 2 of said race 3 one sides.
Further, the said support arm 6 of taking turns can be around said connecting axle 7 rotations.
With reference to Fig. 3, shown in Figure 5; Casing 2 bottom down either side externals adopt the race 3 of profile depression when draw-bar box draws capable state; Case seamed edge place sets up fixed mount 8, and fixed mount 8 has rock-steady structure with pull bar casing 2, and fixed mount 8 is exposed to casing 2 parts and 6 equipped connections of wheel support arm; Fixed mount 8 on wheel support arm 6 and the casing 2 can rotate along casing 2 sides and the location; The race 3 of down either side external is deposited the wheel that has contracted on the casing 2, and wheel 4 is designed to large-size, but is of a size of to greatest extent with the race 3 of pull bar casing 2 down either side externals.
The preferred embodiment that the above is merely the utility model is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
