The specific embodiment

In conjunction with accompanying drawing and embodiment, further structure and the operation principle to the utility model elaborates:

A kind of torsionspring shock-absorbing suitcase; The vertical handle 12 and the horizontal handle 15 of a side and the tow handle 11 that is positioned at horizontal handle 15 opposite sides top that comprise casing 10 tops; Comprise that also being positioned at both sides, horizontal handle 15 opposite sides below respectively has a right angle concave surface castor seat 18; One cover torsionspring shock-absorbing wheels 20 are placed in the right angle concave surface castor seat 18, and as improvement: described torsionspring shock-absorbing wheels 20 comprise torsionspring 25, buffering boss 35, fixedly pivot pin 31, cushioned support wheel carrier 30 and scroll wheel 22 and wheel pivot pin 21 at least; The inclined-plane of buffering boss 35 is fixed on balance arm 23 left sides of cushioned support wheel carrier 30; Fixedly pivot pin 31 passes the rotating hole of torsionspring 25; The spring of torsionspring 25 diverges on the swing arm gusset piece 32 that pin 52 is fixed on cushioned support wheel carrier 30, and the spring connecting pin 51 of torsionspring 25 slides and holding in the palm on the right right-angle plane 26 of right angle concave surface castor seat 18.

As further improvement: be furnished with the identical balance arm 23 of forward and backward two geomeries on the described cushioned support wheel carrier 30, and an end of described balance arm 23 has solid pin-and-hole 39, the other end has wheel shaft pin-and-hole 38; The same side of two balance arms 23 has swing arm gusset piece 32 to be connected.

As further improvement: described right angle concave surface castor seat 18 comprises that left right-angle plane 36 is with right right-angle plane 26 and fixing the fixedly one-sided concave plane 33 of pivot pin 31; And left right-angle plane 36 is vertical with 26 one-tenth of right right-angle planes, and simultaneously perpendicular to one-sided concave plane 33.

The embodiment installation steps and the course of work are following.

Installation steps:

See among Fig. 2, Fig. 5, Fig. 6 that fixedly a termination of pivot pin 31 is fixed on one-sided concave plane 33 walls of right angle concave surface castor seat 18; The solid pin-and-hole 39 of balance arm 23 tops on the cushioned support wheel carrier 30 is slidingly matched with fixing pivot pin 31; The endoporus of scroll wheel 22 and wheel pivot pin 21 are slidingly matched, the wheel shaft pin-and-hole 38 and the wheel pivot pin 21 two ends secure fit of balance arm 23 belows on the cushioned support wheel carrier 30.

The spring of torsionspring 25 diverges on the swing arm gusset piece 32 that pin 52 is fixed on cushioned support wheel carrier 30; Fixedly pivot pin 31 passes the rotating hole of torsionspring 25, and the spring connecting pin 51 of torsionspring 25 slides and holding in the palm on the right right-angle plane 26 of right angle concave surface castor seat 18.

The course of work:

Vertically handle 12 is used for vertically carrying the suitcase; Laterally handle 15 is used for laterally carrying the suitcase.

In Fig. 1, Fig. 2, casing 10 is grasped tow handle 11 by the people and hauls when on the smooth-riding surface, at the uniform velocity walking, and casing 10 is in about 45 degree and leans forward, and buffering boss 35 is in the initial stressed state with torsionspring 25;

In Fig. 3; Control scroll wheel 22 when balance arm 23 and receiving left side resistance; The angle that spring on the swing arm gusset piece 32 that is fixed on cushioned support wheel carrier 30 of torsionspring 25 diverges between pin 52 and the spring connecting pin 51 diminishes, and buffering boss 35 discharges bullet and leaves left right-angle plane 36;

In Fig. 4, to control scroll wheel 22 when balance arm 23 and receiving the right resistance, slide spring connecting pin 51 springs on the right right-angle plane 26 that is holding in the palm right angle concave surface castor seat 18 of torsionspring 25 diverge to angle between the pin 52 and become big release and flick.

To the control of the buffering of balance arm, guarantee that the uneven caused vibrations in road surface are effectively extenuated by means of torsionspring, make operating handle comfortable, thereby prolonged suitcase service life.
