Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
A kind of suitcase being convenient to going up or down stairway of the utility model, as shown in Figure 1, comprise casing 1, casing 1 is provided with a pair support roller 4, casing 1 centre position being in the same face with support roller 4 is also provided with slide rail 7, slide rail 7 direction is parallel with the tangential direction that support roller 4 rotates, chassis slide construction 15 is connected with in slide rail 7, one side relative with being provided with a pair support roller 4 on casing 1 is also provided with pull bar 5, as shown in Figure 2, chassis slide construction 15 is specially: the framework montant 14 comprising pair of parallel setting, the first framework bar 6 is evenly disposed with between pair of parallel framework montant 14, second framework bar 9, 3rd framework bar 12 3 framework bar, the two ends of three framework bars are all through the framework montant 14 at place, termination, form carrier frame, the two ends of three framework bars are also all connected with Athey wheel 2, 6 Athey wheel 2 diameters are all equal, Athey wheel 2 diameter is less than support roller 4 diameter, the Athey wheel 2 at the 3rd framework bar 12 two ends and support roller 4 center of circle are on same straight line, a transport tape is formed after the coated transmission crawler belt 13 of 3 Athey wheels 2 of every root framework montant 14 homonymy, the middle position of described first framework bar 6 is connected with one end of expansion link 10 by connector 8, the other end of expansion link 10 is connected with slide block 11, slide block 11 can slide along the slide rail 7 of casing 1 bottom surface, 3rd framework bar 12 corresponding casing 1 position is also provided with component 3 of putting away sports equipment for a pair, as shown in Figure 3, put away sports equipment on component 3 and all have groove 16, groove 16 opening direction is parallel with the case face at described component 3 place of putting away sports equipment, groove 16 openings of sizes is mated with the 3rd framework bar 12, 3rd framework bar 12 just can snap in groove 16.
A kind of suitcase being convenient to going up or down stairway of the utility model, operation principle is:
When user walks on level and smooth road surface, this suitcase is the same with other suitcases, only need to pull pull bar 5, rotate by a pair support roller 4 and then suitcase is advanced, when user wants going up or down stairway, now, sliding slider 11, slide block 11 is made to slide to the other end in slide rail 7, now expansion link 10 is stretched out, 3rd framework bar 12 of chassis slide construction 15 skids off from the groove 16 of component 3 of putting away sports equipment, connector 8 90-degree rotation, now whole chassis slide construction 15 lands, the transport tape that two width are made up of Athey wheel 2 and transmission crawler belt 13 starts pulling and operate with suitcase, whole suitcase advances, because transmission crawler belt 13 set up by suitcase, Athey wheel 2 rolls in transmission crawler belt 13, run into step, sand ground, snowfield and mud ground or any uneven road surface, wide crawler belt has disperseed the weight of suitcase, Athey wheel 2 is convenient just as walking the Line.Due to chassis slide construction 15 be evenly set gradually the first framework bar 6, second framework bar 9 between framework montant 14 by pair of parallel setting, the 3rd framework bar 12 3 framework bars form carrier frame, so whole chassis slide construction 15 sound construction, chassis slide construction 15 can not be made to fall apart because of the reason on road surface.
A kind of suitcase being convenient to going up or down stairway of the utility model, when user wants going up or down stairway, can decontrol chassis slide construction, for user provides convenient, when user uses suitcase in flat road surface, chassis slide construction can be packed up, prevent unnecessary trouble.
