Technical field

This utility model relates to a kind of draw-bar box, belongs to travel goods.

Background technology

Travelling away from home, for the enough luggage needed of band, first have to the draw-bar box selecting a capacity big, chest is big has weighed handling Car is the most highly difficult, if draw-bar box self can lift or power-assisted people easily can raise chest and reduce, convenient handling side again Just tow, by the biggest time saving and energy saving for travelling process, bring convenience.By in many ways understanding, there is presently no this form merit The draw-bar box of energy exists.

Summary of the invention

In order to solve above-mentioned difficulties, this utility model provides a kind of draw-bar box, it is possible in draw-bar box is carried up and down Slowly put down after draw-bar box is propped up, save manpower.

For achieving the above object, the technical solution adopted in the utility model is:

Draw-bar box, including the casing with pull bar, the trailing flank of casing is provided with a support, and one end of support is articulated with casing Trailing flank top, the other end of support is provided with the wheels that at least two groups are symmetrical, and the medium position of support is connected with a hydraulic cushion The external part of support bar, is provided with the hydraulic cavities of hydraulic oil in hydraulic cushion support bar, the fixing end hinge of hydraulic cushion support bar It is connected to casing.

As preferably, described support is made up of upper bracket and lower carriage two parts, sets folded turning between upper bracket and lower carriage Axle.

As the most preferably, described support includes left support bar and the right support bar of symmetry, and left support bar is in rotating shaft Place is divided into left upper support bar and lower-left support bar and is connected by rotating shaft hinge, right support bar be divided at rotating shaft upper right support bar and Bottom right support bar is also connected by rotating shaft hinge, sets connecting rod between left upper support bar and upper right support bar, and described hydraulic cushion supports The external part of bar is articulated with connecting rod.

Further preferred, buffering cross bar, the two ends of buffering cross bar are fixed in the lower end of described hydraulic cushion support bar Trailing flank by stud connection Yu casing.

As preferably, the end of described lower-left support bar and bottom right support bar sets wheels respectively, and wheels are three wheels The triangle wheels of central shaft interconnection composition.

As preferably, the rear portion indent of described draw-bar box forms support cavity.

The beneficial effects of the utility model are: by hydraulic cushion support bar and the effect of support, make a people the most permissible Heavier draw-bar box is carried easily, it is achieved more labour-saving is loaded and unloaded on automobile, and laborsaving save time.Play draw-bar box fully Tow advantage, allow people carry a large amount of luggage trip no longer difficulty.

Detailed description of the invention

This utility model draw-bar box as depicted, including the casing with pull bar, the trailing flank of casing is provided with a support, One end of support is articulated with the trailing flank top of casing, and the other end of support is provided with the wheels that at least two groups are symmetrical, in support Position, portion is connected with the external part of a hydraulic cushion support bar, is provided with the hydraulic cavities of hydraulic oil, hydraulic pressure in hydraulic cushion support bar The fixing end of cushioning supportive bar is articulated with casing.The rear portion indent of draw-bar box forms support cavity.

Embodiment

Support is made up of upper bracket and lower carriage two parts, sets folding rotating shaft between upper bracket and lower carriage, and support includes Symmetrical left support bar and right support bar, left support bar is divided into left upper support bar and lower-left support bar at rotating shaft and is cut with scissors by rotating shaft Being connected, right support bar is divided into upper right support bar and bottom right support bar at rotating shaft and is connected by rotating shaft hinge, left upper support bar And between upper right support bar, setting connecting rod, the external part of described hydraulic cushion support bar is articulated with connecting rod.Hydraulic cushion support bar The lower end trailing flank by stud connection and casing.The end of lower-left support bar and bottom right support bar sets wheels, wheels respectively It is the triangle wheels of the central shaft interconnection composition of three wheels.

Support 3, hydraulic cushion support bar 4 and wheels 5 in figure are the lifting servomechanism masters constituting and can propping up draw-bar box Want parts.

When draw-bar box is put into automobile boot, Fig. 2 or Fig. 3 state becomes Fig. 4, support separated with casing, The external part of hydraulic cushion support bar is pulled out, people at the pull bar of casing under press, the bottom of casing 1 is at hydraulic cushion support bar Be propped up under the support force effect of 4, horizontal sliding draw-bar box, the lower end of casing 3 put onboard, slip hydraulic cushion support bar 4 with The connection end of support 3, folded-out for the lower carriage of support 3, hydraulic cushion support bar 4 is close together with casing 1, forms Fig. 5 State, at this moment wheels 5 are in the upper end of casing 1, and casing 1 two ends have wheel to be moved easily, and casing 1 can be advanced automobile boot In, regain pull bar 2.
