[0002] The wheel frame of the luggage roller is usually provided with a vertical axis hole, in which a vertical axis is inserted, and the top end of the vertical axis is installed to fix the luggage base on the luggage body. The vertical axis is configured to be axially limited in the vertical axis hole and can rotate in the vertical axis hole. In order to limit the vertical axis in the vertical axis hole, the existing method is to provide a horizontal pin hole opened along the vertical axis hole on the wheel frame, and a horizontal pin is inserted in the horizontal pin hole. The horizontal pin part is inserted into the vertical axis hole, and a circle of annular grooves is provided on the vertical axis. The horizontal pin is stuck in the annular groove, so that the vertical axis is limited in the vertical axis hole through the horizontal pin, and then the end of the horizontal pin is limited in the horizontal pin hole by riveting. Under this design, the vertical axis is fixed by a horizontal pin, which has the defects of low assembly efficiency and high cost. Summary of the invention

[0006] Preferably, at least one pair of elastic clamping feet is provided in the window hole, and the pair of elastic clamping feet are arranged opposite to each other on two lateral sides of the vertical axis hole.

[0007] Preferably, the bottom end edge of the vertical shaft is chamfered to form a chamfered surface, and as the bottom of the vertical shaft is inserted into the vertical shaft hole at a position corresponding to the window hole, the chamfered surface contacts and pushes with the clamping end of the elastic clamping foot.

[0008] Preferably, the elastic clamping foot is arranged upside down in the window hole with the clamping end facing the bottom of the vertical axis hole.

[0009] Preferably, the elastic clamping foot is fixed on the window hole wall of the wheel frame by integral injection molding with the wheel frame.

[0010] By adopting the above technical scheme, when assembling the vertical shaft, the vertical shaft is inserted into the vertical shaft hole, the end of the vertical shaft presses the clamping end of the elastic clamping foot, the elastic clamping foot is elastically deformed, and when the vertical shaft is inserted into the annular groove and the clamping end of the elastic clamping foot corresponds to the position, the clamping end of the elastic clamping foot is restored under the action of elastic force, and the clamping end of the elastic clamping foot is clamped into the annular groove, so that the vertical shaft is axially limited in the vertical shaft hole through the elastic clamping foot, and because the annular groove is a circle around the vertical shaft, the vertical shaft can rotate relative to the elastic clamping foot; this makes the assembly of the vertical shaft simpler and improves the assembly efficiency, especially, the elastic clamping foot is integrally injection molded with the wheel frame, and the processing and assembly are relatively convenient.

[0011] The utility model is further described below in conjunction with the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 3 for Figure 2 Sectional view taken along line AA. DETAILED DESCRIPTION

[0015] See attached Figures 1 to 3 The utility model discloses a luggage roller wheel frame assembly, including a wheel frame 1, a vertical axis hole 11 is provided on the wheel frame 1, a vertical axis 2 is inserted in the vertical axis hole 11, the vertical axis 2 is arranged in the vertical axis hole 11 and can rotate relative to the wheel frame 1, and a ring groove 21 is provided at the lower end of the vertical axis 2 around the circumference, and a window hole 12 is provided on the wheel frame 1, the window hole 12 corresponds to the bottom position of the vertical axis hole 11 and passes through the vertical axis hole 11 laterally, and an elastic foot 13 that can be elastically deformed is provided in the window hole 12, and the elastic foot 13 is in a free state, and the clamping end 131 of the elastic foot 13 extends into the vertical axis hole 11, and the elastic foot 13 can be deformed by the vertical axis 2 inserted into the vertical axis hole 11, and when the vertical axis 2 is inserted into the ring groove 21 and corresponds to the clamping end 131, the clamping end 131 of the elastic foot 13 falls into the ring groove 21 (such as Figure 1 and Figure 3As shown). The elastic foot 13 and the wheel frame 1 are integrally injection molded to simplify the overall processing and assembly process of the wheel frame assembly, reduce costs and facilitate assembly operations; therefore, those skilled in the art can think of fixing the elastic foot to the wheel frame via a fastener. Preferably, the elastic foot 13 and the wheel frame 1 are integrally injection molded, and the elastic foot 13 is fixed to the wall of the window hole 12 of the wheel frame 1. When the vertical shaft is assembled, the vertical shaft is inserted into the vertical shaft hole, and the end of the vertical shaft presses the clamping end of the elastic clamping foot, and the elastic clamping foot is elastically deformed. When the vertical shaft is inserted into the annular groove and the clamping end of the elastic clamping foot corresponds to the position, the clamping end of the elastic clamping foot is restored under the action of elastic force, and the clamping end of the elastic clamping foot is clamped into the annular groove, so that the vertical shaft is axially limited in the vertical shaft hole through the elastic clamping foot, and because the annular groove is a circle around the vertical shaft, the vertical shaft can rotate relative to the elastic clamping foot; this makes the assembly of the vertical shaft simpler and improves the assembly efficiency; there is no need to be equipped with equipment for riveting operations of the cross pin, thereby reducing the manufacturer's production cost; and the elastic clamping foot and the wheel frame are integrally injection molded, which further reduces product costs.

[0016] In order to ensure that the vertical axis is limited and the movement is stable and reliable, at least one pair of elastic feet 13 is provided in the window hole 12, and the pair of elastic feet 13 are arranged oppositely on the lateral sides of the vertical axis hole 11. The symmetrical arrangement of the elastic feet ensures that the limiting action points of the vertical axis are symmetrical, so that the fixing of the vertical axis is stable and reliable.

[0017] When assembling the vertical shaft, the elastic foot is directly pushed. In order to better drive the elastic foot, the bottom end edge of the vertical shaft 2 is chamfered to form a chamfered surface 22. As the bottom of the vertical shaft 2 is inserted into the vertical shaft hole 11 at a position corresponding to the window hole 12, the chamfered surface 22 contacts and pushes with the clamping end 131 of the elastic foot 13. Similarly, the clamping end of the elastic foot also adopts a corresponding inclined surface design.

[0018] In this specific embodiment, Figure 1 and Figure 3 As shown, the elastic foot 13 is arranged upside down in the window hole 12 with the clamping end 131 facing the bottom of the vertical shaft hole 11. It has the advantages of simple and compact structure; in addition, it is easier to integrally inject the elastic foot on the wheel frame.
