Embodiment 1

[0034] Such as figure 1 with figure 2 As shown, Embodiment 1 of the present invention relates to a luggage case provided with folding wheels, comprising: a luggage case body 1, a pull rod 2 arranged on the back of the luggage case body 1 and a universal wheel 3 arranged at the bottom of the luggage case body 1, The lower half of the suitcase body 1 is also provided with a folding wheel; the folding wheel includes a wheel 4 and a pivot mechanism 5, and the wheel 4 is pivotally connected to the suitcase body 1 through a pivot mechanism 5; the pivot mechanism 5 includes a fixed shaft 51 and a rotation reset Device 52; the rotation reset device 52 is set on the outside of the fixed shaft 51, and the fixed shaft 51 is fixed on the trunk body 1, and the rotation reset device 52 is connected to the wheels 4; the rotation reset device 52 can be in a working position and a Rotate between the stowed positions, and the rotating reset device 52 can reset to the stowed position from the ...

Embodiment 2

[0047] Such as Figure 5 with Figure 8 As shown, the difference between this embodiment and Embodiment 1 is that: a rocker 526 is fixedly connected to the bottom of the rotating shaft 523, and the rocker 526 is parallel to the bottom surface of the luggage case body 1; Connected to the end of the rocker 526, the pull cord 8 can drive the rocker 526 to rotate between a working position and a stowed position.

[0048] The rocking bar 526 is positioned at the bottom of the suitcase body 1, and the rocking bar 526 is fixed on the bottom of the rotating shaft 523. The bottom of the suitcase is provided with a channel 13 whose two right-angle sides are respectively parallel to the vertical plane and the horizontal plane, and the stay cord 8 passes through it. Connect the rocker 526 after passing through the channel 13. The channel 13 changes the pull cord 8 from the vertical direction to the horizontal direction. When the folding wheel needs to be used, pull the pull rod 2 upward....

Embodiment 3

[0055] Such as Figure 9 As shown, the difference between this embodiment and Embodiments 1 and 2 is that the folding wheels are arranged at the bottom of the side of the suitcase body 1, and the receiving space 11 may not be provided. When the folding wheels are unfolded, the rotating shaft 523 is moved by Rotate outward 180 degrees from the starting position to the working position, so that the wheels 4 are located on the back of the suitcase body 1 and are perpendicular to the back of the suitcase body 1, and the suitcase can be pulled obliquely, which is convenient to use; when the folding wheels are put away, The wheels 4 are accommodated at the side of the luggage case body 1, which does not take up extra space and is convenient to use. When in use, only the wheels 4 need to be unfolded or retracted manually.

Abstract

The invention relates to a trunk with folding wheels. The trunk with the folding wheels comprises a trunk main body, and the folding wheels are arranged at the lower half part of the trunk main body; the folding wheels comprise wheels and pivot joint mechanisms, and the wheels are pivoted to the trunk main body through the pivot joint mechanisms; the pivot joint mechanisms comprise fixed shafts and rotation reset devices; the rotation reset devices rotationally sleeve the fixed shafts, the fixed shafts are fixed on the trunk main body, and the rotation reset devices are connected with the wheels; each rotation reset device can rotate between a working position and a retracted position around the corresponding fixed shaft, and can reset to the retracted position from the working position without being subjected to forces; a blocking piece used for limiting each rotation reset device is arranged at one end of each fixed shaft. The folding wheels are used as spare wheels, so that the folding wheels can be unfolded to be used when road conditions are poor or universal wheels of the trunk main body are damaged, without causing extra burdens for users; the rotation reset devices drive the wheels to automatically return from the working positions to the retracted positions, thereby saving labor and not occupying extra space.

Description

technical field [0001] The invention relates to a receiving device, in particular to a suitcase provided with folding wheels. Background technique [0002] At present, the suitcases on the market generally have a hard box body, a retractable pull rod and 2-4 universal wheels, which have outstanding advantages such as beauty, convenience, easy towing / push, and effective protection for the contained items.
