Description

Technical Field

[0001] This utility model relates to the field of luggage technology, and more specifically, to a luggage moving wheel that is easy to install. Background Technology

[0002] With the increasing frequency of travel, luggage has become widely used as a means of carrying personal belongings. Most luggage on the market consists of a first shell, a second shell, a pull rod, and wheels, with the wheels installed at the bottom corners of both shells. Existing wheels typically include a shell mounting base, a connecting post, a wheel seat, wheels, and an axle. Two wheels are connected to the wheel seat via the axle. The upper end of the connecting post connects to the shell mounting base, and the lower end of the connecting post needs to be inserted into the longitudinal mounting hole of the wheel seat to engage with a steel ball installed in the hole. However, the manufacturing and assembly of such wheels is cumbersome. It requires pre-setting a groove on the inner wall of the longitudinal mounting hole for the steel ball to enter. The steel ball must first be placed in the groove at the lower end of the connecting post before being inserted into the longitudinal mounting hole along with the connecting post. This process is time-consuming, labor-intensive, inefficient, and costly. Utility Model Content

[0003] The purpose of this invention is to overcome the above-mentioned defects in the prior art and provide a convenient bag and luggage moving wheel with a simpler structure, easier assembly, time and labor saving, greatly improved assembly efficiency, and low production cost.

[0004] To achieve the above objectives, this utility model provides a conveniently installed luggage wheel, including a luggage shell fixing base, a connecting column, a wheel seat, wheels, and axles. The upper end of the connecting column is connected to the luggage shell fixing base, and the lower end of the connecting column is inserted into the longitudinal mounting hole of the wheel seat and connected to the wheel seat. Two wheels are provided and connected to the wheel seat through the axles. The lower end of the connecting column is provided with a lower end limiting head with an inverted T-shaped cross-section. A concave limiting groove is formed between the lower head of the lower end limiting head and the lower end of the connecting column. The bottom edge of the longitudinal mounting hole of the wheel seat is provided with several buckles that are centrally distributed and inclined inward. The buckles can be engaged in the limiting groove of the connecting column, and the top of the lower head of the lower end limiting head can abut against the bottom of the buckle, thereby limiting the lower end of the connecting column through the buckles.

[0005] Preferably, the upper end of the connecting column is provided with a limiting washer located between the connecting column and the housing fixing seat. The upper end of the connecting column passes through the mounting hole of the housing fixing seat and the center hole of the limiting washer and is then connected to the limiting washer by stamping and riveting to achieve limiting.

[0006] Preferably, the outer wall of the connecting column is provided with a raised ring, which is located between the housing fixing seat and the wheel seat.

[0007] Preferably, the wheel seat and the buckle are integrally injection molded from plastic material.

[0008] Preferably, the upper end of the housing fixing base is provided with several reinforcing ribs and several screw mounting holes.

[0009] Preferably, the bottom edge of the lower end of the lower limiting head is chamfered.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] This invention features several undercuts at the bottom edge of the longitudinal mounting hole of the wheel seat. When the connecting post is fully inserted into the longitudinal mounting hole of the wheel seat, the undercuts can engage with the limiting groove of the connecting post, and the top of the lower end of the limiting head can abut against the bottom of the undercut, thereby limiting the lower end of the connecting post through the undercuts. This invention has a simpler structure, is easier to assemble, saves time and effort, greatly improves assembly efficiency, and has low production costs. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] Please refer to Figure 1 and Figure 2 The present invention provides a convenient luggage wheel, including a luggage shell fixing base 1, a connecting column 2, a wheel seat 3, a wheel 4, and a wheel axle 5. The components of the present invention will be described in detail below with reference to the accompanying drawings.

[0020] like Figure 2 and Figure 3 As shown, the upper end of the connecting column 2 is connected to the housing fixing seat 1. In a specific implementation, preferably, the upper end of the connecting column 2 can be provided with a limiting washer 6 located between the connecting column 2 and the housing fixing seat 1. After the upper end of the connecting column 2 passes through the mounting hole of the housing fixing seat 1 and the center hole of the limiting washer 6, it can be limited by stamping and riveting with the limiting washer 6. After the upper end of the connecting column 2 is stamped and riveted, its upper end will expand outward, thereby forming an upper limiting head that cooperates with the limiting washer 6 for limiting.

[0021] like Figure 3 and Figure 5 As shown, the lower end of the connecting post 2 is provided with a lower end limiting head 21 with an inverted T-shaped cross-section. A concave limiting groove 22 is formed between the lower head of the lower end limiting head 21 and the lower end of the connecting post 2. The connecting post 2 is made of metal.

[0022] like Figure 4 and Figure 5 As shown, the bottom edge of the longitudinal mounting hole of the wheel seat 3 is provided with several inverted buckles 31 that are centrally distributed and inclined inward. The number of inverted buckles 31 can preferably be four, and the four inverted buckles 31 can form a through hole with a diameter smaller than that of the longitudinal mounting hole. The wheel seat 3 and the inverted buckles 31 can be integrally injection molded from rigid plastic material.

[0023] Preferably, in order to facilitate the lower end limiting head 21 of the connecting column to pass through the through hole surrounded by the buckle 31, the bottom edge of the lower end head of the lower end limiting head 21 can also be provided with a chamfer.

[0024] like Figure 2 and Figure 5As shown, when the connecting post 2 is inserted downward into the longitudinal mounting hole of the wheel seat 3, the lower end limiting head 21 of the connecting post 2 will push open the buckle 31. When the connecting post 2 is inserted into place, the buckle 31 can be inserted into the limiting groove 22 of the connecting post 2, and the top of the lower end of the lower end limiting head 21 can abut against the bottom of the buckle 31, thereby limiting the lower end of the connecting post 2 through the buckle 31.

[0025] like Figure 2 and Figure 3 As shown, the outer wall of the connecting column 2 may be provided with a protruding ring 23, which is located between the housing fixing seat 1 and the wheel seat 3, and can limit the housing fixing seat 1 and the wheel seat 3.

[0026] like Figure 1 As shown, the upper end of the housing mounting base 1 may also be provided with several reinforcing ribs 11 and several screw mounting holes 12.

[0027] like Figure 1 and Figure 2 As shown, there are two wheels 4, and the two wheels 4 can be connected to the wheel seat 3 through the wheel axle 5.

[0028] In summary, the structure of this utility model is simpler, assembly is more convenient, time and labor are saved, assembly efficiency is greatly improved, and production costs are low.
