Description

Technical Field

[0001] This utility model relates to the field of luggage technology, specifically a suitcase. Background Technology

[0002] Suitcases are common items used for daily storage. In a niche market, there is a type of suitcase with a foot pedal. This suitcase can function in two ways: first, as a scooter, and second, as a bag. This suitcase is mainly for children, who can step on the foot pedal to move it. Therefore, the foot pedal needs to be able to support the weight of the child.

[0003] The applicant believes that in the prior art, the footrest is mainly supported by two wheels located at the bottom of the bag and a rear wheel located at the rear of the footrest. The two wheels and the rear wheel provide three-point support for the footrest. This design results in limited footrest support. Due to the size difference between Chinese and foreign children, heavier children need stronger footrest support when using the suitcase to ensure safety. On the other hand, it is difficult for the suitcase to stand independently after the footrest is folded up, because the increased weight of the footrest causes the center of gravity of the suitcase to shift to the rear.

[0004] Therefore, the applicant proposes a suitcase that enhances the support of the footrest and facilitates stable standing when the suitcase needs to stand independently after the footrest is folded. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the defects of the prior art and propose a suitcase that enhances the support capacity of the footrest and is conducive to the stable standing of the suitcase when the footrest is folded and the suitcase needs to stand independently.

The support has a rear extension that is rotatably hinged to the front end of the foot pedal. The rear extension has a support on the lower side of the front end of the foot pedal, and the support is connected to an auxiliary wheel.

[0007] When the front end of the pedal rotates clockwise around the rear extension and unfolds into position, the two side wheels, auxiliary wheels, and rear wheels provide support for the pedal. When the front end of the pedal rotates counterclockwise around the rear extension and retracts into position, the two side wheels and auxiliary wheels provide bottom support for the bag.

[0008] In some embodiments, the extension includes a front end connected to the middle of the bracket and a rear end located on one side of the front end of the pedal. The front end is inserted into the rear end and is rotatably connected to the rear end in a plane. The extension is rotatably hinged to the front end of the pedal. The extension has a support on the lower side of the front end of the pedal. This means that the rear end is rotatably hinged to the front end of the pedal and the rear end has a support on the lower side of the front end of the pedal.

[0009] In some embodiments, the support is arranged obliquely downward and backward, and the support includes two supports arranged side by side on both sides of the auxiliary wheel.

When the front end of the pedal is rotated clockwise around the rear extension and unfolded into place, the support shafts support the two side walls upward to indirectly support the front end of the pedal.

[0011] In some embodiments, both side walls are provided with arc-shaped recesses. When the front end of the pedal rotates clockwise around the rear extension and unfolds into place, the arc-shaped recesses cooperate with the corresponding support shafts.

[0012] In some embodiments, two support shafts are provided on each side, one in front of the other. Each support shaft is connected to a connecting rod. The lower end of the connecting rod is rotatably connected to its respective support shaft, and the upper end of the connecting rod is rotatably connected to the side wall of the U-shaped opening. There are a total of four connecting rods on both sides, and the four connecting rods control the folding direction of the pedal.

[0013] In some embodiments, when the front end of the pedal is rotated clockwise around the rear extension and unfolded into place, the front connecting rod is in a vertical state, while the side walls are engaged with the corresponding support shafts vertically, and the front connecting rod and the support shafts together support the front end of the pedal upward.

[0014] Compared with the prior art, the present invention has the following advantages after adopting the above structure: The present invention solves the problem through improvement. Specifically, when the front end of the pedal is rotated clockwise around the rear extension and unfolded into place, the two box wheels, the auxiliary wheel and the rear wheel provide support for the pedal. When the front end of the pedal is rotated counterclockwise around the rear extension and retracted into place, the two box wheels and the auxiliary wheel provide bottom support for the bag.

[0015] Therefore, this utility model provides a suitcase that enhances the support capacity of the footrest and also helps the suitcase to stand stably when it needs to stand independently after the footrest is folded. Attached Figure Description
