Four avoidance plates that can avoid when receiving impact are arranged at the four corners of the bottom of the box body through an avoidance device, and universal wheels are also arranged on the avoidance plates.

[0005] Further improvement: The avoidance device includes: mounting plates arranged at the four corners of the bottom of the box body, and wave plates respectively arranged on both sides of the mounting plates for connecting the avoidance plates, and the wave plates will deform when pressed.

[0006] Further improvement: A guiding device between the avoidance plate and the mounting plate.

[0007] Further improvement: The guiding device includes: four guide sleeves evenly arranged on the avoidance plate, guide posts arranged on the mounting plate, and an anti-deviation and anti-slip device for improving stability when obliquely dragging the rolling suitcase is also arranged between the guide posts and the guide sleeves.

[0008] Further improvement: The anti-deviation and anti-slip device includes: at least four first strip-shaped arc grooves formed around the inside of the guide sleeve and extending to the end of the guide sleeve, second strip-shaped arc grooves on the guide post matching the first strip-shaped arc grooves, and a plurality of guiding balls arranged between the first strip-shaped arc grooves and the second strip-shaped arc grooves.

[0009] Further improvement: An adjusting device for further fine-tuning the elastic force is also arranged on the guide sleeve.

[0010] Further improvement: The adjusting device includes: an adjusting thread formed on the outer side of the guide sleeve, an adjusting nut locked on the guide sleeve, and a spring sleeved on the guide sleeve with one end resisting against the mounting plate and the other end against the adjusting nut.

[0011] Further improvement: The inner diameter of the spring matches the guide sleeve to prevent deviation.

[0012] Further improvement: A rubber pad is also provided at the bottom of the guide post to prevent the guide post from colliding with the avoidance plate and generating impact sound.

[0013] Further improvement: A TPE silent sleeve is also sleeved on the roller of the universal wheel.

[0014] The advantages and beneficial effects of the present utility model are as follows:

[0015] The structure is simple and easy to use. The universal wheels are installed on the avoidance plate, and an avoidance device is provided between the avoidance plate and the mounting plate, so that the universal wheels can avoid when pressed, thereby reducing the impact on the box body, playing a shock-absorbing role, improving the safety of the luggage in the box body, and improving the convenience of use.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] 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.

[0020] As Figure 1 - Figure 2 shown, a noise-reducing and shock-absorbing luggage includes a box body 1 and a pull rod 2 provided on the box body 1. Four avoidance plates 3 that can avoid when receiving impact are provided at the four corners of the bottom of the box body 1 through an avoidance device, and universal wheels 4 are also provided on the avoidance plates 3.

[0021] In order to reduce the vibration of the box body 1 when moving on bumpy roads, the avoidance device includes: mounting plates 5 provided at the four corners of the bottom of the box body 1, and corrugated plates 6 respectively provided on both sides of the mounting plates 5 for connecting the avoidance plates 3, and the corrugated plates 6 will deform when pressed.

[0022] In order to improve the stability of the avoidance plate 3 during avoidance, a guiding device is provided between the avoidance plate 3 and the mounting plate 5. The guiding device includes: four guide sleeves 7 evenly arranged on the avoidance plate 3, and a guide post 8 arranged on the mounting plate 5. An anti-deviation and anti-slip device is also provided between the guide post 8 and the guide sleeve 7 to improve the stability when the inclined towing rod 2 is towing the box.

[0023] In order to improve the smoothness of the cooperation between the guide post 8 and the guide sleeve 7 and the stability when towing the box body 1 obliquely, the anti-deviation and anti-slip device includes: at least four first strip-shaped circular arc grooves 9 formed around the inner side of the guide sleeve 7 and the first strip-shaped circular arc grooves 9 extend to the end of the guide sleeve 7, a second strip-shaped circular arc groove 10 provided on the guide post 8 and matching the first strip-shaped circular arc grooves 9, and a number of guiding balls 11 arranged between the first strip-shaped circular arc grooves 9 and the second strip-shaped circular arc grooves 10.

[0024] In order to facilitate further adjustment according to the weight of the luggage in the box body 1, an adjustment device for further fine-tuning the elastic force is also provided on the guide sleeve 7. The adjustment device includes: an adjustment thread (not shown in the figure) formed on the outer side of the guide sleeve 7, an adjusting nut 12 locked on the guide sleeve 7, and a spring 13 sleeved on the guide sleeve 7 with one end resisting against the mounting plate 5 and the other end against the adjusting nut 12.

[0025] In order to prevent the spring 13 from shifting, the inner diameter of the spring 13 matches the guide sleeve 7 to prevent shifting.

[0026] In order to reduce the noise that may be generated when the guide post 8 touches the bottom, a rubber pad 14 is also provided at the bottom of the guide post 8 to prevent the guide post 8 from colliding with the avoidance plate 3 and generating an impact sound.

[0027] In order to reduce the noise when pushing the towing rod 2 box, a TPE silent sleeve 15 is also sleeved on the roller of the universal wheel 4.

[0028] Working principle: When in use, load the luggage into the box body 1, and then turn the adjusting nut 12 to further adjust the elastic force between the avoidance plate 3 and the mounting plate 5. When the user drags the box body 1 through a bumpy section, the impact of the universal wheel 4 against the obstacles on the road surface will drive the avoidance plate 3 to move towards the mounting plate 5, thereby reducing the impact force during impact and reducing the vibration in the box body 1.

[0029] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and descriptions only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
