The present invention is comprised of casing, free rotating tension bar, double-lever mechanism and stopping means, and two footing of casing are equipped with the first castor; Free rotating tension bar is comprised of two these pull bars of foundation and two telescopic levers, and two these pull bars of foundation all share with the second fork the multidiameter that a Double bearing support being fixed on casing supports; Double-lever mechanism is comprised of the first fork, connecting rod, the second fork and casing, one end and the casing of the first fork are hinged, the other end of the first fork and rod hinge connection, the other end of connecting rod and the second fork are hinged, upper end and the casing of the second fork are pivotally connected, and the second fork footing is provided with the second castor; Stopping means is arranged on connecting rod and second and lays out, stopping means is comprised of spacer pin and control pin, spacer pin is to consist of spacing key seat, the first spring, spacing shank, embedded end cap, spacing key seat is fixed on the second fork, spacing shank activity is located in the transverse holes of spacing key seat, the front end of spacing shank arranges the first spring, the sheathed embedded end lid in rear portion of spacing shank, tapered being convenient in rear end of spacing shank, can not relatively rotate connecting rod and the locking of the second fork at the hole through connecting rod Shang; Controlling pin is to consist of the second spring, control key seat and control shank, controls shank activity and is located in the hole of controlling key seat, and the front end of controlling shank arranges the second spring, and the second spring is between control shank and connecting rod.
The operation principle of stopping means is, do not need by pressure-controlled shank, rotate the second fork to spacing shank when relative with connecting rod Shang hole, spacing shank is under the pushing tow of the first spring, spacing shank stretches out the hole through connecting rod Shang from spacing key seat hole, connecting rod and the locking of the second fork can not be relatively rotated; By pressure-controlled shank, control shank and compress the second spring to the spacing shank of ejection, rotate the second fork and make spacing shank compress the first spring and return in spacing key seat hole, remove connecting rod and the locking of the second fork.
The course of work of the present invention and principle:
Draw-bar box is placed in to erectility, rotates the second fork to hearing that spacing shank only ejects, rotate casing to three castor and land, rotate and stretch out free rotating tension bar and just can draw its walking;
Draw-bar box is placed in to erectility, by pressure-controlled shank and rotate the second fork, the second fork is proceeded in the groove of casing, until the second fork blocks by fixture block, retract and rotating tension bar is blocked by fixture block, casing is in laying state.If article are lighter in empty van or case, the pull bar of the draw-bar box in laying state is pulled out to use the same with commercially available draw-bar box.
Beneficial effect of the present invention:
The present invention is simple in structure, good looking appearance, dependable performance, the laborsaving people's speed of travel that do not affect, and can reduce by a relatively large margin the labour intensity that people draw draw-bar box, improves happy that people go on business or travel.That people are going on business or the indispensable a kind of smaller vehicle of whilst on tour.
