Description
Technical field
The utility model relates to luggage case, and more particularly, it relates to the telescopic luggage case of a kind of roller.
Background technology
People's trip all can be with the thing of big bags and small bags, the articles for use and luggage case is also absolutely necessary, not only help people to free both hands, various travelling necessary articles are put into luggage case, and in luggage case, in perfect order placing articles is also convenient for people to sort articles after arriving destination.The roller of current luggage case is on the market all non-telescoping, and roller is to protrude outside casing, and still, when luggage case is obsolete, the roller that cannot stretch back takes up room, and bad stacking.
Utility model content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of roller telescopic luggage case.
For achieving the above object, the utility model provides following technical scheme: the telescopic luggage case of a kind of roller, comprise casing, roller and be the scalable compensation linkage being arranged on casing, in described casing, be provided with air cavity, described compensation linkage is arranged in air cavity, one side of the corresponding roller of described compensation linkage is provided with first piston, the other gas outlet that is provided with of opposite side of the corresponding compensation linkage of described air cavity, on described gas outlet, be connected with the second piston, one side of the corresponding roller of described the second piston is provided with compound rod, described compound rod is that connecting rod connects support bar, the two ends of described support bar are connected with roller.
The utility model is further set to, in described casing, be provided with air cavity, air cavity is in the middle of casing, described compensation linkage is arranged in air cavity, one side of the corresponding roller of described compensation linkage is provided with first piston, the opposite side of the corresponding compensation linkage of described air cavity is provided with closure plate, and described closure plate is closed by the mode of snap close, and the opposite side of the corresponding compensation linkage of closure plate has rubber ring.
By adopting technique scheme, air cavity is located in the middle of casing, and user when in use casing is stressed evenly, there will not be monolateral phenomenon of toppling over.When using luggage case, the length of compensation linkage is fixed, between the piston of inflator and barrel, there is space, on piston, have individual to recessed piston.When upwards drawing piston, the volume of air of piston below increases, and pressure reduces, and the air of piston top is just extruded into below from piston surrounding.When pressing down piston, piston below volume of air is dwindled, and pressure increases, and makes piston be tight against barrel and does not allow air drain to piston top.When using the air cavity arranging in casing, air cavity can not rock up and down, allows user's one direction that masterpiece is used on pull bar.
The utility model is further set to be connected with the second piston on described gas outlet, and the opposite side side of the corresponding compensation linkage of described air cavity is provided with gas outlet, and whether gas outlet is controlled and ventilated with the external world by screw thread stopper.
By adopting technique scheme, when using luggage case, inflator inner volume increases, pressure increases, and the air of first piston top is just extruded into the second piston below, and piston is pushed over to bottom, when not using luggage case, user outwards winding screw thread stopper, firmly presses down casing, first piston and the second piston are all drawn close each other, volume reduces, and pressure increases, thereby causes the air in air cavity to be discharged towards gas outlet, after Bas Discharged, roller and compound rod reset.
Of the present utility modelly further be set to, on described closure plate, the both sides of corresponding adjusting yoke and the second piston are provided with rubber ring, are provided with for the fixing fixed part of closure plate on described casing.
By adopting technique scheme, rubber ring has sealing function, prevents that the air in air cavity from overflowing.Be provided with closure plate and contribute to pin closure plate with respect to the air of the air cavity of the second piston portion, keep roller constant in a state.
The side that the utility model is further set to the corresponding roller of described the second piston is provided with connecting rod, and the other end of corresponding the second piston of described connecting rod is connected with support bar.
By adopting technique scheme, the second piston, to corresponding roller one lateral movement of the second piston, drives connecting rod and support bar to move to same direction, in the middle of described two connecting rods, has a support bar, support two connecting rods, avoid unbalance stress to cause two connecting rods outwardly-bent.
Of the present utility modelly further be set to, offer the chute for closure plate slippage in described air cavity, described chute is communicated with casing.
By adopting technique scheme, the effect of chute be when fixed block is moved with moving direction restriction in the same horizontal line, in case the fixed block disengaging direction of motion in motion process.
Of the present utility modelly further be set to, described fixed part includes the clip being movably arranged on casing and is arranged on fixed head the fixed block suitable with clip.
By adopting technique scheme, when fixed block moves to the position of the clip on casing, clip is fixed block fixedly, in case fixed part rocks, plays fixation.
Of the present utility modelly further be set to, on described casing, be provided with the groove for described support bar and the motion of described connecting rod.
By adopting technique scheme, it is fluted that casing is pressed close to connecting rod one side, and restriction compound rod double swerve and teetertottering in motion process, has played spacing effect.
Compared with prior art; advantage of the present utility model can be reduced to luggage case the inside obsolete time; and the luggage case that can stretch when using is that luggage case is used air cavity can reach casing damping effect on uneven ground; luggage in protection luggage case does not jolt and makes luggage top disorderly because of section, plays the effect of protection luggage.When luggage case is obsolete, can not take up room by flexible roller, conveniently stack.
