[0024] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0025] It should be noted that if the embodiments of the present application involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative positional relationship, movement condition, etc. between components in a certain specific posture (as shown in the drawings), and if the specific posture changes, the directional indications also change accordingly.

[0026] The utility model provides a box wheel connecting base.

[0027] In the embodiment, referring to Figures 1-6 , the box wheel connecting base comprises a base 1 and a quick release assembly for detachably connecting the base 1 and a vertical shaft of a roller, the base is provided with a mounting cavity 2 for mounting the quick release assembly and a shaft hole 3 for connecting the vertical shaft of the roller, the quick release assembly comprises a dial 4, a buckle 5, an elastic member 6 and a bottom cover 7, the buckle is movably mounted in the mounting cavity, the elastic member has a pressure for pressing the buckle to one side of the shaft hole, one end of the dial is provided with a rotating shaft 8, a wedge-shaped step 9 is arranged on the side surface of the dial, the dial passes through a buckle groove 10 of the buckle and extends out of the surface of the base, the bottom of the buckle groove is provided with a limiting arc surface 11, the bottom cover 7 covers the mounting cavity, and the rotating shaft is rotationally matched with a shaft groove 12 on the bottom cover.

[0028] In the above technical solution, the quick release assembly composed of the dial, the buckle, the elastic member and the bottom cover and the corresponding mounting cavity and the shaft hole on the base are arranged, so that the detachable connection between the vertical shaft of the roller and the base is realized. The rotating shaft of the dial is rotationally matched with the shaft groove of the bottom cover, and the wedge-shaped step on the side surface is designed, so that the user can change the position state of the buckle by operating the dial, thereby easily controlling the connection and separation between the vertical shaft of the roller and the base, greatly improving the convenience and efficiency of the disassembly and assembly of the roller, simplifying the operation process of luggage maintenance and roller replacement and improving the user experience.

[0029] The specific principle is as follows: Figure 3As shown, at this time, the position, the dial piece to the shaft hole side pressure, in the state of connecting the roller vertical axis. When need to unlock, push the dial piece to the left, in the process of pushing, the wedge-shaped step pressure on the side of the dial piece slot, push the dial piece to continue moving to the left, make the dial piece away from the shaft hole, complete the unlocking, after the wedge-shaped step overcomes the dial piece slot to reach the limit arc surface, because the limit arc surface, the dial piece cannot return to the original position, at this time, in the relative static state of unlocking. Conversely, the dial piece to the right, after the wedge-shaped step overcomes the upper dial piece slot, return to Figure 3 As shown, in the locking state, at this time, the wedge-shaped step overcomes the upper dial piece slot, also cannot return to the original position, in the relative static state of locking.

[0030] Specifically, one end of the dial piece is provided with a spring shaft 13, one end of the elastic member is connected with the spring shaft, and the other end is abuttingly connected with the bottom wall of the mounting cavity.

[0031] In the embodiment, the spring shaft is arranged on the dial piece and connected with the elastic member. The structure that one end of the elastic member is connected with the spring shaft and the other end is abuttingly connected with the bottom wall of the mounting cavity can stably provide the dial piece with pressure towards the side of the shaft hole. This ensures that the dial piece can be closely matched with the roller vertical axis in the normal use state, effectively prevents the roller from accidentally falling off due to external factors such as vibration, enhances the reliability and stability of the connection between the roller and the base, and guarantees the safety of the luggage during movement.

[0032] In addition, the elastic member can be a coil spring which is sleeved with the spring shaft to ensure the connection stability of the elastic member.

[0033] Specifically, both sides of the mounting cavity are provided with elastic hooks 14, and both sides of the bottom cover are provided with connecting steps 15 for buckling with the elastic hooks 14.

[0034] In the embodiment, the elastic hooks on both sides of the mounting cavity are matched with the connecting steps on both sides of the bottom cover. This screwless connection mode facilitates the installation and disassembly of the bottom cover.

[0035] Specifically, an arc-shaped opening 16 adapted to the roller vertical axis is arranged on the end of the dial piece away from the elastic member.

[0036] In the embodiment, the arc-shaped opening adapted to the roller vertical axis is arranged on the end of the dial piece away from the elastic member, so that the contact between the dial piece and the roller vertical axis is more closely and accurately, the force can be evenly dispersed, and the stability of the connection is further enhanced.

[0037] Specifically, the bottom cover is provided with a mounting column 17, and the mounting column 17 is provided with a mounting hole 18.

[0038] In the embodiment, the mounting column is arranged on the upper side of the base and has a mounting hole, which provides a convenient mounting structure for connecting the base with other parts (such as a box frame and the like) of the luggage case. According to different design requirements and structural features of the luggage case, appropriate connecting members (such as bolts and the like) can be selected to firmly fix the base on the box body through the mounting hole, so that the base can better adapt to diversified overall structural design of the luggage case, and the versatility and adaptability of the base in different luggage case products are improved.

[0039] Specifically, one side of the connecting step has a guide slope 19.

[0040] In the embodiment, the guide slope is arranged on one side of the connecting step, and when the bottom cover is installed, the guide slope can guide the elastic hook to smoothly slide into the connecting step, thereby reducing the difficulty of installing the bottom cover and reducing the possibility of damaging the elastic hook or the connecting step due to improper installation.

[0041] Skilled persons should know that although the utility model has been described according to the above specific embodiments, the utility model idea is not limited to the utility model, and any modification using the utility model idea will be included in the patent protection range.
