Detailed ways

The utility model discloses a suitcase with an adjustable auxiliary load-bearing wheel frame. Referring to FIG. 1, it includes a box body 1 and an auxiliary load-bearing wheel frame. The auxiliary load-bearing wheel frame includes a support frame 2 and a clamping part 3, and the support frame 2 can rotate relative to the box body 1 and form an angle with the ground to support the box body 1; the clamping member 3 is used to fix the position of the support frame 2.

This embodiment increases the auxiliary load-bearing wheel frame on the basis of the traditional suitcase, supports the box body 1 through the supporting frame 2, and fixes the position of the supporting frame 2 through the clamping member 3; solves the problem in the prior art when loading articles When the weight is heavy, dragging will take more physical strength, and the box body is easy to topple over, thus ensuring the stability of the suitcase. The support frame 2 in this embodiment can rotate relative to the box body 1 and form different angles with the ground, which is convenient for the user to adjust the support angle of the support frame according to actual needs. Optionally, the included angle is 0-170°.

Specifically, in yet another embodiment, the support frame 2 includes two support rods 21 , the two support rods 21 are connected by a rotating rod 22 , and the rotating rod 22 is movably connected with the box body 1 . In this embodiment, the rotating rod 22 rotates relative to the box body 1 so that the support frame 2 can rotate relative to the box body 1 so that the support frame 2 forms an included angle with the ground to support the box body 1 .

Further, in yet another embodiment, a roller 23 is installed at the end of each of the two support rods 21 . It is convenient for the user to drag the box body 1 .

Specifically, in yet another embodiment, referring to FIG. 3 , the clamping member 3 includes a control rod 31, a ratchet 32 and a latch 33, the ratchet 32 is provided with a plurality of ratchet grooves, and the ratchet 32 is fixed on the On the rotating lever 22 of the control lever 31, the latch 33 can be inserted into or disengaged from the ratchet groove under the action of the control lever 31. When the latch 33 is embedded in the ratchet groove, the position of the rotating rod 22 can be fixed; when the latch 33 is out of the ratchet groove, the rotating rod 22 can rotate relative to the box body 1 . Optionally, two ratchets 32 are provided on the rotating rod 22 , and two corresponding latches 33 are provided to ensure the clamping effect of the clamping member 3 .

Further, referring to Fig. 4, the clamping member 3 also includes an upper control plate 34, a lower control plate 35, a plurality of springs 36, a tight bottom plate and a plurality of connecting rods 37, the upper control plate 34, the lower control plate 35 Distributed on both sides of the ratchet 32, the upper control board 34 and the lower control board 35 are connected by a plurality of connecting rods 37, the control rod 31 is connected with the upper control board 34, and the tight bottom board is installed on the box On the body 1, one end of multiple springs 36 is connected to the lower control board 35, and the other end of multiple springs 36 is connected to the tight bottom plate.
