Description
Technical field
The present invention relates to daily necessities, and in particular to luggage case.
Background technique
Trolley case, top are equipped with pull rod, and the bottom of generally telescopic pull rod, trolley case is equipped with idler wheel, general quantity
For two or four.When pulling the trolley case, idler wheel lands, and holds the pull rod, and trolley case is integral inclined, and user bears
Trolley case moiety by weight.
Summary of the invention
Technical problem solved by the invention: when user's movement trolley case, it is not subjected to the weight of trolley case.
In order to solve the above technical problems, the invention provides the following technical scheme: a kind of Roller bag, including cabinet, it is mounted on
The left and right sides of one idler wheel of the bottom of box, cabinet is articulated with support pulley by drive-connecting shaft, and support pulley and drive-connecting shaft are solid
Fixed connection, drive-connecting shaft are flexibly connected with cabinet, and support pulley can rotate forward with drive-connecting shaft and be hidden in the side of cabinet, branch
Support pulley can be rotated backward with drive-connecting shaft and the side wall far from cabinet, with the idler wheel at the state of standing like the legs of a tripod；Support pulley
It is configured with limit assembly, the limit assembly includes salient point plate, salient point flat spring, and salient point plate is mounted on the drive-connecting shaft, convex
Contact plate can be equipped with pit along the axial movement of drive-connecting shaft, the side wall of cabinet, and salient point flat spring is arranged in salient point plate and support
Between pulley, under the action of the salient point flat spring, the salient point on salient point plate can cooperate in the pit.
Salient point quantity on salient point plate is at least one, and the quantity of pit is several, several one circles of pits composition, round
Center fall on the axial line of drive-connecting shaft.
When case for storing, the support pulley of cabinet two sides is hidden in the side of cabinet, i.e. Left-side support pulley is tightly attached to case
The left side of body, Right side support pulley are tightly attached to the right side of cabinet.When needing mobile box, any support pulley, the support are acted
Pulley drives another support pulley to rotate synchronously by drive-connecting shaft, supports side of the pulley far from cabinet.At left and right sides of cabinet
The idler wheel of support pulley and the bottom of box lands simultaneously, and at the state of standing like the legs of a tripod, at this point, cabinet leans forward, the weight of cabinet is complete
By idler wheel and two support pulley supports, user may act on the top of cabinet, control direction, mobile box.
Drive-connecting shaft rotation, salient point plate and support pulley rotate with it, wherein salient point plate is only capable of opposite drive-connecting shaft and makees axial move
It is dynamic.Salient point on salient point plate overcomes the elastic potential energy of salient point flat spring, enters adjacent pit from a pit, in salient point plate bullet
Under the elastic force effect of spring, the cooperation of salient point and pit can play position-limiting action to support pulley, avoid support pulley with pivot joint
Axis arbitrarily rotates, and especially when supporting pulley to be in receiving state, support pulley will not optionally be unfolded, and needs external biggish
Masterpiece is used to support pulley, overcomes the elastic potential energy of salient point flat spring, can just make to support pulley expansion.
The present invention carries user, and chest is more convenient, and trip is lighter.
