Universal wheels are also arranged between the standing feet and the reinforcement plate through a quick-release device.

[0006] Further improvement is that: the quick-release device includes: a mounting post arranged on the universal wheel, an annular seat arranged on the reinforcement plate and having the same axis as the standing foot, and a clamping device arranged between the annular seat and the mounting post.

[0007] Further improvement is that: the clamping device includes: a clamping ring groove opened on the mounting post, a fixing rod fixedly arranged on the annular seat, a first arc-shaped block fixedly arranged on the fixing rod and used for clamping with the clamping ring groove, a second arc-shaped block slidably arranged on the annular seat through an elastic reset device, an inclined block arranged on the second arc-shaped block, and an inclined groove opened on the clamping ring groove and matching the inclined block.

[0008] Further improvement is that: the elastic reset device includes: a sliding rod arranged on the second arc-shaped block, a sliding hole opened on the annular seat and matching the sliding rod, a spring sleeved on the sliding rod with one end resisting against the second arc-shaped block and the other end resisting against the annular seat, and a limiting pull block arranged on the sliding rod on the side outside the annular seat.

[0009] Further improvement is that: the sliding rod is cross-shaped, and the sliding hole is arranged to match the sliding rod.

[0010] Further improvement is that: a guiding device is also arranged between the mounting post and the standing foot.

[0011] Further improvements are as follows: The guiding device includes a guiding groove formed in the mounting post and matching the standing feet, and an anti-rotation device arranged between the guiding groove and the standing feet.

[0012] Further improvements are as follows: The anti-rotation device includes at least one anti-rotation groove formed in the standing feet, and an anti-rotation plate arranged in the guiding groove and configured to cooperate with the anti-rotation groove.

[0013] Further improvements are as follows: A pull rod for facilitating the movement of the box body is further arranged on the box body.

[0014] Further improvements are as follows: A handle for facilitating the lifting of the box body is further arranged on the side of the box body.

[0015] The advantages and beneficial effects of the present utility model are as follows:

[0016] The structure is simple and the use is convenient. The universal wheels are connected through a quick-release device, so that it is convenient for the user to replace the universal wheels when they are damaged.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The following combines the drawings and embodiments to further describe the specific embodiments of the present utility model. The following embodiments are only used to more clearly illustrate the technical solutions of the present utility model and cannot be used to limit the protection scope of the present utility model.

[0023] AsFigures 1-3 As shown in Figures 1-3 , a luggage case with detachable wheels includes a case body 1. A reinforcing plate 2 is provided at the bottom of the case body 1. Four standing feet 3 are provided at the four corners of the bottom of the reinforcing plate 2. A universal wheel 4 is also provided between the standing feet 3 and the reinforcing plate 2 through a quick-release device.

[0024] To facilitate the installation of the universal wheel 4, the quick-release device includes: a mounting post 5 provided on the universal wheel 4, an annular seat 6 provided on the reinforcing plate 2 and having the same axis as the standing foot 3, and a clamping device provided between the annular seat 6 and the mounting post 5.

[0025] To enhance the stability of the universal wheel 4 after installation, the clamping device includes: a clamping ring groove 7 opened on the mounting post 5, a fixing rod 21 fixedly provided on the annular seat 6, a first arc-shaped block 8 fixedly provided on the fixing rod 21 and used for clamping with the clamping ring groove 7, a second arc-shaped block 9 slidably provided on the annular seat 6 through an elastic reset device, an inclined block 10 provided on the second arc-shaped block 9, and an inclined groove 11 opened on the clamping ring groove 7 and matching the inclined block 10.

[0026] To facilitate the installation positioning and removal of the universal wheel 4, the elastic reset device includes: a sliding rod 12 provided on the second arc-shaped block 9, a sliding hole 13 opened on the annular seat 6 and matching the sliding rod 12, a spring 14 sleeved on the sliding rod 12 with one end resisting against the second arc-shaped block 9 and the other end resisting against the annular seat 6, and a limit pulling block 15 provided on the side of the sliding rod 12 outside the annular seat 6.

[0027] To improve the sliding stability of the second arc-shaped slider, the sliding rod 12 is cross-shaped, and the sliding hole 13 is provided to match the sliding rod 12.

[0028] To enhance the force stability of the universal wheel 4 after installation, a guiding device is further provided between the mounting post 5 and the standing foot 3. The guiding device includes: a guiding groove 16 opened on the mounting post 5 and matching the standing foot 3, and an anti-rotation device provided between the guiding groove 16 and the standing foot 3.

[0029] To prevent the part of the universal wheel 4 connected to the case body 1 from rotating, the anti-rotation device includes: at least one anti-rotation groove 17 opened on the standing foot 3, and an anti-rotation plate 18 provided in the guiding groove 16 and used for cooperating with the anti-rotation groove 17.

[0030] To facilitate pulling the case body 1, a pull rod 19 for facilitating the movement of the case body 1 is further provided on the case body 1.

[0031] To facilitate lifting the case body 1, a handle 20 for facilitating the lifting of the case body 1 is further provided on the side of the case body 1.

[0032] Working principle: When installing the universal wheel 4, the anti-rotation plate 18 in the installation guiding groove 16 is directly inserted by aligning with the anti-rotation groove 17 on the standing foot 3. At this time, under the action of the inclined block 10, the second arc-shaped block 9 gradually slides, so as to avoid the space for the installation column 5 to move, and resets when the inclined groove 11 corresponds to the inclined block 10. At this time, the installation column 5 cooperates with the first arc-shaped block 8 and the second arc-shaped block 9 to complete the fixation.

[0033] When disassembling, the user can smoothly complete the disassembly by pulling the limit pull block 15 with one hand and pulling the universal wheel 4 with the other hand, and the replacement is convenient.

[0034] The above shows and describes the basic principle, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and descriptions only illustrates the principle of the present utility model.
