Description

The cart type suitcase

Technical field

The utility model is about a kind of suitcase, but refers to that especially a kind of foot rest with opening and closing is with auxiliary cart type suitcase of advancing.

Background technology

Suitcase is used in the long-distance travel mostly, carry luggage for the user, and transport for convenient user, therefore many suitcases all can be provided with four rolling in the flat bottom of casing, suitcase can move on the ground smoothly thus, and this external suitcase rear also can be provided with a pull bar, is available for users to spur suitcase, when the pulling suitcase, two rollers in the place ahead soar to such an extent as to suitcase tilts to lean on two rollers at rear to land rolling.

Yet, prior art only has the suitcase of pull bar and roller, between promoting or spurring, only utilize two rollers to land mobile, but when load-carrying is big, mobile suitcase is difficult thing in fact under the labile state of having only two rollers to land, the user must utilize the strength of hand to control the gradient and the direction of suitcase, topples over or erects to prevent it, and this is a kind of puzzlement for the user of suitcase.

The utility model content

Because aforesaid the deficiencies in the prior art point, the purpose of this utility model is to provide a kind of cart type suitcase with auxiliary foot rest of advancing.

For achieving the above object, the technological means that the utility model adopted is, a kind of cart type suitcase, and it comprises:

One casing, its bottom is provided with a plurality of rollers;

One rod assembly, it is located at the casing trailing flank, include a crossbeam that laterally is fixed at the casing trailing flank, be provided with a pillar in crossbeam respectively near the place, both sides, this two pillar is distinguished up, extend the lower end, and the upper end of pillar is provided with the leader, and the pillar lower end is provided with at least one main wheel, and two pillar spans are provided with an auxiliary girder, and it is positioned at the crossbeam downside; Rod assembly includes a main locking bar in addition, it wears through crossbeam and auxiliary girder, and its top end pull handle that is shaped, and the bottom extends the auxiliary girder downside, and laterally extend respectively in the upper and lower side place of corresponding auxiliary girder and to be provided with a cross bar, and between cross bar and auxiliary girder, leaned a spring respectively;

One foot rest assembly, it includes bipod, a tranverse connecting rod and two support arms; Wherein the bipod upper end is corresponding respectively is hubbed on the two ends of crossbeam, and the lower end of foot rest is respectively equipped with an auxiliary wheel; Tranverse connecting rod is connected between bipod, and forms a main lock dog on it, its towards casing extend and selectivity corresponding to the bottom of main locking bar, and run through on the block and be provided with a main lockhole, its bottom that optionally is set in main locking bar is with fixing foot rest; Support arm is connected between pillar and the tranverse connecting rod to limit the maximum pivoting angle of foot rest.

From the above mentioned, when the user opens foot rest and makes the casing hypsokinesis, the center of gravity of casing can be stablized between the main wheel that drops on foot rest auxiliary wheel and pillar, therefore additionally the application of force to keep its angle of inclination, has the advantage of saving the application of force and easy operation, moreover, the function that the design of cooperation locking bar can provide user one that foot rest is folded really.
