AI Technical Summary
When existing suitcases are transported on bumpy roads, relying solely on rubber rollers cannot provide good vibration-absorbing buffering, resulting in unstable items in the box.
A shock absorbing device for a suitcase is designed, including a universal wheel body, a shock absorbing assembly and a compression spring. The shock absorbing assembly consists of a connecting plate, a fixing plate, a rubber plate, a mounting plate and a compression spring, which provides buffering between the luggage compartment and the universal wheel body through a compression spring, and protects the compression spring through a removable mounting base and bellows.
Through the cushioning effect of the compression spring, the shock absorption effect of the suitcase on bumpy roads is significantly improved, the service life of the compression spring is extended, and the contact with the roller through the sponge strip is carried out to remove gravel and sand on the roller to avoid damage.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of luggage case shock absorption, and more specifically to a shock absorption device for a luggage case. Background Art
[0002] A suitcase, also known as a travel case or a trolley case, is a box used to carry items when going out. It is a type of luggage that is mainly pulled and transported by rollers at the bottom of the suitcase. When a suitcase travels on a bumpy road, it mainly relies on the material of the rubber rollers for vibration reduction and buffering to protect the items in the suitcase. However, rubber rollers alone cannot provide good and stable vibration reduction and buffering. Therefore, it is urgent to design a shock-absorbing device for a suitcase. Utility Model Content
[0003] In order to overcome the above defects of the prior art, the utility model provides a shock absorbing device for a luggage case to solve the problems existing in the above background technology.
[0004] The utility model provides the following technical solution: a shock absorbing device for a suitcase, comprising a device body, the device body comprising a universal wheel body, a shock absorbing assembly being fixedly installed on the top of the universal wheel body, the shock absorbing assembly comprising a connecting plate, the connecting plate being fixedly installed on the top of the universal wheel body, a fixing plate being provided on the top of the connecting plate, a rubber plate being fixedly installed on the top of the fixing plate, a mounting plate being fixedly installed on the top of the rubber plate, the mounting plate being connected to the suitcase, a mounting seat being installed on one side of the fixing plate and the connecting plate close to each other by screws, the mounting seats being open on one side of the fixing plate and the connecting plate close to each other, a compression spring being placed inside the mounting seat between the connecting plate and the fixing plate, the compression spring being installed between the fixing plate and the connecting plate by a detachable mounting seat, providing a buffer between the suitcase and the universal wheel body by the compression spring during movement, and being conveniently disassembled and replaced after elastic fatigue occurs to the compression spring.
[0005] Furthermore, a bellows is sleeved on the outer side of the mounting seat between the connecting plate and the fixing plate, and the compression spring between the mounting seats is wrapped and protected by the bellows to prevent the compression spring from being directly exposed.
[0006] Furthermore, there are four mounting seats between the connecting plate and the fixing plate, and the four mounting seats are respectively located at four corners of the connecting plate and the fixing plate on a side close to each other, thereby increasing the stability and strength of the connection between the connecting plate and the fixing plate.
[0007] Furthermore, the inner walls of the mounting seats between the connecting plate and the fixing plate are fixedly mounted with limit blocks, and the limit blocks are all located inside the compression springs. The limit blocks increase the stability of the compression springs between the mounting seats.
[0008] Furthermore, a damper is fixedly installed on the top end of the connecting plate, and the telescopic end of the damper is fixedly connected to the bottom end of the fixed plate. The damper can buffer and absorb the vibration of the compression spring to increase stability.
[0009] Furthermore, a sponge strip is installed at the bottom end of the connecting plate through Velcro, and the sponge strip at the bottom end of the connecting plate fits with the roller on the universal wheel body, which is convenient for cleaning the roller surface on the universal wheel body and avoids stones from continuously adhering to the roller and increasing damage to the roller.
[0010] Technical effects and advantages of the utility model:
[0011] 1. The utility model is provided with a shock-absorbing component. This design allows a compression spring to be installed between a fixed plate and a connecting plate through a detachable mounting seat. During movement, the compression spring provides a buffer between the suitcase and the universal wheel body. When elastic fatigue occurs to the compression spring, it can be easily disassembled and replaced.
[0012] 2. The utility model adopts this design so that when the roller on the universal wheel body rolls, some stones and sand adhering to the roller can be swept off through the contact between the sponge strip and the roller, avoiding the situation where the stones and sand continue to adhere to the roller and cause damage.

DETAILED DESCRIPTION
[0018] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention.
[0019] Example 1: Reference Figure 1-4The utility model provides a shock absorbing device for a suitcase, including a device body 100, the device body 100 includes a universal wheel body 110, a shock absorbing assembly 200 is fixedly installed on the top of the universal wheel body 110, the shock absorbing assembly 200 includes a connecting plate 210, the connecting plate 210 is fixedly installed on the top of the universal wheel body 110, a fixing plate 215 is provided on the top of the connecting plate 210, a rubber plate 216 is fixedly installed on the top of the fixing plate 215, a mounting plate 217 is fixedly installed on the top of the rubber plate 216, the mounting plate 217 is connected to the suitcase, and a mounting seat 211 is installed on the side where the fixing plate 215 and the connecting plate 210 are close to each other through screws, and the side where the mounting seat 211 is close to each other is an open design. A compression spring 212 is placed inside the mounting seat 211 between the connecting plate 210 and the fixing plate 215, a bellows 214 is sleeved on the outer side of the mounting seat 211 between the connecting plate 210 and the fixing plate 215, there are four mounting seats 211 between the connecting plate 210 and the fixing plate 215, and the four mounting seats 211 are respectively located at the four corners on the side where the connecting plate 210 and the fixing plate 215 are close to each other, and the inner wall of the mounting seat 211 between the connecting plate 210 and the fixing plate 215 is fixedly installed with a limit block 213, and the limit block 213 is located inside the compression spring 212, and a damper 218 is fixedly installed on the top of the connecting plate 210, and the telescopic end of the damper 218 is fixedly connected to the bottom end of the fixing plate 215.
