Abstract
The invention discloses a retractable draw-bar box idler wheel which comprises an idler wheel base, a wheel and a universal shaft, wherein a wheel retracting mechanism is arranged on the idler wheel base; the retracing mechanism is controlled by a button; a groove is formed in one side of the idler wheel base; the wheel can be retracted after being bent by 90 degrees and then is fixed in the groove; the wheel is fixed on the universal shaft by a detectable dual-riveting structure. According to the draw-bar box idler wheel provided by the invention, the wheel can be bent by 90 degrees and then is contained in the groove by the retracing mechanism, so that the actual volume of a box body is increased under a condition of same box size; the wheel can be kept stable under during upright and bending-retracting by the idle wheel retracting mechanism due to the matching of a push rod and the positioning groove; the wheel is fixed by the detectable two-riveting structure and can be replaced, so that the service life of a whole draw-bar box is prolonged.
Description
Technical field
The present invention relates to a kind of draw-bar box roller, specifically a kind of contractile draw-bar box roller.
Background technology
Draw-bar box, as the instrument of trip, is used widely.At present, the size of carrying the luggage case of boarding has strict regulation, in the structural design of existing draw-bar box, because roller exists certain height, actual portable box volume is diminished.In addition, draw-bar box roller in use weares and teares very fast, and the roller of existing draw-bar box often cannot be changed separately, and this point has affected the service life of draw-bar box greatly.
Summary of the invention
The object of this invention is to provide a kind of contractile draw-bar box roller.
What the present invention solved is that the structural design of existing draw-bar box roller diminishes the actual box volume of draw-bar box, and exists roller the defect such as cannot change.
The technical scheme that technical solution problem of the present invention adopts is: a kind of contractile draw-bar box roller, comprise roller pedestal, wheel and universal drive shaft, and described roller pedestal is provided with wheel contracting mechanism; Described contracting mechanism is by button control; One side of described roller pedestal is provided with groove; Described wheel can be fixed in described groove through 90 degree bending after-contraction; Described wheel is fixed on described universal drive shaft by dismountable pair of riveted construction.
Further, described wheel contracting mechanism comprises the cover plate be located on roller pedestal, holds out against spring, control lever, push rod, is located at the contraction axis of wheel universal drive shaft top and is positioned at the first locating slot, the second locating slot on described contraction axis; Described locating slot and described push rod match; One end of described control lever is connected with described control button by button connector, and the other end is provided with spring holddown groove; Described one end that holds out against spring is connected with described spring holddown groove, and the other end is connected with the spring locating dowel of described cover plate end; Described push rod is positioned at the below of described control lever, is connected with control lever.
Further, described cover plate and described control lever are L-shaped; Angle between described the first locating slot and described the second locating slot is 90 degree.
The invention has the beneficial effects as follows: compared with prior art, draw-bar box roller provided by the invention, by roller contracting mechanism, can spend roller 90 in the rear income of bending groove, thereby the in the situation that of identical FCL volume, the actual volume of casing is increased; Described roller contracting mechanism, by the matching design between push rod and locating slot, makes wheel all can keep stable when upright and bending are shunk; Wheel is fixed by dismountable pair of riveted construction, can change, and has extended the service life of whole draw-bar box.

The specific embodiment
Below in conjunction with drawings and Examples, the invention will be further described.
As shown in Fig. 1～5, a kind of contractile draw-bar box roller, comprises roller pedestal 2, wheel 4 and universal drive shaft 5, and described roller pedestal 2 is provided with wheel contracting mechanism 6; Described contracting mechanism is controlled by button 1; One side of described roller pedestal 2 is provided with groove 3; Described wheel 4 can be fixed in described groove 3 through 90 degree bending after-contraction; Described wheel 4 is fixed on described universal drive shaft 5 by dismountable pair of riveted construction.Described wheel contracting mechanism 6 comprises the cover plate 7 be located on roller pedestal, holds out against spring 13, control lever 11, push rod 12, is located at the contraction axis 9 of wheel universal drive shaft top and is positioned at the first locating slot 8, the second locating slot 16 on described contraction axis; Described locating slot 8 matches with described push rod 12; One end of described control lever 11 is connected with described control button 1 by button connector 10, and the other end is provided with spring holddown groove 15; Described one end that holds out against spring 13 is connected with described spring holddown groove 15, and the other end is connected with the spring locating dowel 14 of described cover plate end; Described push rod 12 is positioned at the below of described control lever 11, is connected with control lever.Described cover plate 7 and described control lever 11 are L-shaped; Angle between described the first locating slot 8 and described the second locating slot 16 is 90 degree.
As shown in Figures 3 and 5, when roller is during in upright rotatable state, insert in the first locating slot 8 in Fig. 3 the end of described push rod 12, and owing to being subject to holding out against the effect that holds out against of spring 13, roller can be fixed under erectility.When pressing the button 1, described control lever 11 together retreats together with described push rod 12, the end of described push rod 12 is left in described the first locating slot 8, now wheel is bent, after 90 degree upwards bend, the second locating slot 16 in Fig. 3 rotates to bottom position, and now push rod 12 can insert in described the second locating slot 16; Equally, owing to being subject to holding out against the effect that holds out against of spring 13, now wheel 4 can be retracted and be fixed in described groove 3.
