Description
Technical field
The utility model relates to a kind of case and bag, and more particularly, it relates to a kind of height-adjustable drawbar case.
Background technology
Draw-bar box refers to have the luggage case of pull bar and roller.Easy to use because of it, carrying clothing etc. becomes travelling, gos out and is widely used.Draw-bar box can portablely also can drag, we at ordinary times the wheel of draw-bar box used be substantially all positioned at chest bottom.Along with the quickening of modern society's rhythm of life speed, that gos out and go on a long journey is frequent, and draw-bar box is to go out to carry the first selection of luggage and articles instrument.
At present, the draw-bar box on market, it comprises casing, expansion link and pulley gear.Although this draw-bar box globality is stronger, for the good road surface of most of road conditions, can pass through smoothly, but run into after rain puddle or road conditions poor time, the trafficability characteristic of draw-bar box is poor, usually need staff lifting rod case to pass through, affected so undoubtedly people's trip, also improved the difficulty of trip, if now still use by force pulley to pass through this section, easily drench casing or casing is caused to damage.
Utility model content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of height-adjustable drawbar case, easily by the poor section of the road conditions such as puddle.
For achieving the above object, the utility model provides following technical scheme:
A kind of height-adjustable drawbar case, comprise casing and castor mechanism, described castor mechanism comprises rigid castors and movable castor, be connected with rocking bar between the two, the two ends of described rocking bar are hinged with rigid castors, movable castor respectively, described rigid castors is fixedly connected with casing, described movable castor and casing removably connect, the middle part of described rocking bar is connected with support bar, one end and the rocking bar of described support bar are hinged, its other end is provided with fixed part, and described casing is provided with for locking the fixture of fixed part.
By adopting technique scheme, when crossing the good section of road conditions, only the rocking bar of castor mechanism need be turned to horizontal positioned, movable castor contacts supporting box with lower box, need to be by the poor section of road conditions time, only rocking bar need to be turn 90 degrees around rigid castors dextrorotation, then the fixture of support bar and casing below is fixed.Now originally the castor of level is vertical shape, and the height of the draw-bar box that raise has improved the trafficability characteristic of draw-bar box, and casing has been played to protective effect.
The utility model is further set to: described rocking bar upside has storage tank.
By adopting technique scheme; when when by the good road surface of road conditions; rocking bar horizontal positioned; now support bar can be placed in to the storage tank of rocking bar upside; not only support bar is had to a stealthy placement effect; also protected support bar, avoided support bar on the normal impact of using of draw-bar box simultaneously.
Further, described fixed part is set to draw-in groove, and described fixture is set to crotch.
By adopting technique scheme, when when by puddle or the poor road surface of road conditions, the crotch clamping below the draw-in groove on support bar and casing, makes crotch have a fixation to support bar, does not allow support bar freely rotate.Rocking bar now, support bar and casing have formed a triangular structure, have realized the stable of castor mechanism.
Further, described crotch can arrange a plurality of.
By adopting technique scheme, when the fixed part of support bar, when carrying out clamping, can realize by different crotch the adjustment of box body of draw-bar box height, realized the Height Adjustable property of draw-bar box.
As concrete technical scheme of the present utility model, described movable castor arranges a clamping mechanism.
By adopting technique scheme, when draw-bar box is normally used on the good road surface of road conditions, movable castor can be connected on casing, make whole draw-bar box globality stronger.
As concrete technical scheme of the present utility model, described clamping mechanism comprises rotation fixture block and movable castor.
By adopting technique scheme, when needs are connected on casing by movable castor only need to by movable castor and lower box near, then by rotation, rotate fixture block, movable castor is stuck on casing, when needs are dismantled clamping mechanism, only need to rotate rotation fixture block, movable castor and casing are departed from, this clamping mechanism removes and installs conveniently, and stability is strong.
As concrete technical scheme of the present utility model, described rotation fixture block is fixed by screws on casing.
By adopting technique scheme, one end of screw is threaded with casing, and the other end and the other end support rotating fixture block, has realized rotation fixture block whenever and wherever possible on casing, facilitates draw-bar box to carry out height adjusting whenever and wherever possible.
Compared with prior art, the utility model has the advantage of: different draw-bar box height are in the past unadjustable, utilize adjustable castor mechanism, and the height of having realized draw-bar box is adjustable, has improved the trafficability characteristic of draw-bar box for different road surfaces, has protected casing.
