Abstract
The invention discloses track type luggage wheels for climbing stairs. The track type luggage wheels comprise a groove-shaped bracket into which two guide wheel bracket plates are fixed, wherein the two guide wheel bracket plates are parallel with each other; an upper guide wheel shaft and a lower guide wheel are arranged between the end parts of the two guide wheel bracket plates; a track slide plate is fixed between the two guide wheel bracket plates; an upper guide wheel and a lower guide wheel are respectively arranged on the upper guide wheel shaft and the lower guide wheel shaft; an O-shaped track positioned on the track slide plate is arranged between the upper guide wheel and the lower guide wheel in a sleeving manner; transverse concave-convex teeth are arranged in the outer surface of the tracks; the inner surface of the track is smooth and seamless; a backstop with a circular cross section is arranged between the bracket and the track; and two ends of the backstop are arranged on the bracket. The track type luggage wheels for climbing the stairs have the advantages of being simple in structure, convenient to use, small in size, and enabling various draw-bar boxes to climb steps and stairs easily.
Description
Technical field
The present invention relates to stair climbing wheel, relate in particular to a kind of crawler type case and bag stair climbing wheel.
Background technology
In daily life, we often need to lift to weight upstairs or, if there is no elevator, implement very difficult downstairs.Particularly, in travelling, with heavy case and bag, hurry back and forth back and forth, upper trouble very downstairs, although existing case and bag mostly at the bottom of case or side pulley has been installed, the difficulty while can't resolve downstairs, still needs people to lift while above going downstairs.For this reason, people have invented three-wheel or the coaxial stair climbing wheel of four-wheel, during use, this stair climbing wheel need to be arranged on to case and bag bottom or carry in addition, if this stair climbing wheel is arranged on to case and bag bottom, because volume is large, have affected the original overall appearance of case and bag; If carried in addition, also because volume is large, carry very trouble.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, and provide a kind of simple in structure, easy to use, volume is little, can make various rod-pulling type case and bag climb steps and stair easily, and does not affect the crawler type case and bag stair climbing wheel of the original overall appearance of case and bag.
The object of the present invention is achieved like this: it comprises the troffer that is fixed on Castor for trunk or bag top, in support, be fixed with two wheel bracket plates that are parallel to each other, between support and wheel bracket, having can be by the gap of crawler belt, between the end of two wheel bracket plates, be respectively equipped with upper block axle and lower guide wheel shaft, between two wheel bracket plates, be fixed with crawler belt slide plate, on upper block axle and lower guide wheel shaft, be respectively equipped with upper block and lower tumbler, between upper block and lower tumbler, cover has O shape crawler belt, described crawler belt is positioned on crawler belt slide plate, described crawler belt outer surface is provided with horizontal shaggy tooth, internal track surfaces is smooth seamless shape.
Between described support and crawler belt, being provided with cross section is circular holdback, and described holdback two ends are located on support.
Between described support and wheel bracket plate, be provided with fixed screw.
Owing to adopting technique scheme, crawler type case and bag stair climbing wheel tool provided by the invention has the following advantages: simple in structure, easy to use, volume is little, can make various rod-pulling type case and bag climb steps and stair easily, and does not affect the original overall appearance of case and bag.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is use state diagram of the present invention.
Wheel bracket plate in the drawings, 1, support, 2,, 3, upper block axle, 4, lower guide wheel shaft, 5, crawler belt slide plate, 6, upper block, 7, lower tumbler, 8, crawler belt, 9, shaggy tooth, 10, holdback, 11, fixed screw, 12, stair, 13, pull bar, 14, case and bag, 15, castor, 16, crawler type case and bag stair climbing wheel.
The specific embodiment
As shown in Figure 1 to Figure 2, crawler type case and bag stair climbing wheel provided by the invention comprises troffer 1, in support 1, be fixed with two wheel bracket plates 2 that are parallel to each other, between the end of two wheel bracket plates 2, be respectively equipped with upper block axle 3 and lower guide wheel shaft 4, between two wheel bracket plates 2, be fixed with crawler belt slide plate 5, on upper block axle 3 and lower guide wheel shaft 4, be respectively equipped with upper block 6 and lower tumbler 7, between upper block 6 and lower tumbler 7, cover has O shape crawler belt 8, described crawler belt 8 is positioned on crawler belt slide plate 5, described crawler belt 8 outer surfaces are provided with horizontal shaggy tooth 9, crawler belt 8 inner surfaces are smooth seamless shape, between described support 1 and crawler belt 8, being provided with cross section is circular holdback 10, described holdback 10 two ends are located on support 1, between described support 1 and wheel bracket plate 2, be provided with fixed screw 11.
During concrete use, crawler type case and bag stair climbing wheel 16 of the present invention is fixed on case and bag 14 bodies.2 crawler type case and bag stair climbing wheels 16 are installed on each case and bag 14.In the time of fixedly, the support 1 of crawler type case and bag stair climbing wheel 16 is fixed on to the case and bag 14 body back sides, leans on above case and bag 14 castors 15, also can merge one with case and bag 14 pony sills.When running into step, casing is slightly tilted, allow 12 jiaos, top stair of crawler belt 8 in crawler type case and bag stair climbing wheel 16, horizontal shaggy tooth 9 in crawler type case and bag stair climbing wheel 16 blocks 12 jiaos, stair, and when at this moment people hauls case and bag 14 pull bars 13 and upwards draws, crawler belt 8 just slides on the crawler belt slide plate 5 between upper block axle 3 and lower guide wheel shaft 4, case and bag 14 just move up easily, when if case and bag 14 are heavier, to open holdback 10 and just can prevent that case and bag 14 are toward gliding, case and bag 14 have been pulled on more easily.While going downstairs, close holdback 10, that then case and bag 14 are tilted is placed on 12 jiaos, stair, then pushes away case and bag 14 pull bars 13, and at this moment case and bag 14 rely on crawler belts 8 just can along stair 12, go down easily, very convenient.
