Detachable bag track device

Abstract

The invention belongs to the technical field of trolley cases for travel and particularly relates to a detachable bag track device. In order to solve the using limitation and design problems of existing bag track device, the invention provides a detachable bag track device which comprises a trolley system and a track walking system, wherein the track walking system comprises two groups annular track devices parallel to each other; a bag is symmetrically clamped in the annular track devices; the two groups of annular track devices are connected as a whole through the trolley system; an independent spring system is arranged in the annular track device; the top of the annular track device is connected with the trolley system; and a fold with a smart lock is arranged at the bottom of the track device. Through the device provided by the invention, the problem that traditional bag cannot walk on an uneven bad road can be effectively solved; and moreover, since the bags are independent of each other, the device with a detachable combination structure can be applied to all traditional bags.

Description

technical field [0001] The invention belongs to the technical field of trolley cases for travel, and in particular relates to a detachable crawler device for luggage. Background technique [0002] In the current society, luggage has become an indispensable tool for going out to work, study, travel, etc., and people's requirements for the volume and capacity of luggage are also increasing. However, today's bags are basically composed of universal wheels, casings and telescopic pull rods. It is okay to move on flat ground, but when encountering a large vertical height or uneven road surface, due to the small axle of the universal wheel and the small contact area with the ground, it will cause tilting, overturning and other phenomena. It will not pass smoothly. At this time, people will choose to lift the luggage, which is very laborious. For this reason, people have invented three-wheel coaxial stair climbing wheel, but this stair climbing wheel volume is too large, is not e...

AI Technical Summary

Problems solved by technology

[0003] One: Once the track is damaged, it is impossible to go uphill or up the stairs. There is no emergency method, only manual handling

[0004] Two: The crawler itself does not have a spring system. When walking on terrain with a high vertical height, it cannot guarantee the smooth operation of the luggage, which will cause damage to the luggage itself.

[0005] Three: The trolley and the bag are integrated rods, without angle adjustment, which does not take into account the different angles required by people of different heights when passing through terrain with different vertical heights, which sometimes causes unnecessary troubles

However, it has not considered that the pulleys will also cause the bag to overturn on uneven ground or special terrain such as grass

[0007] Most of the tracked bags invented today are integrated with the track and the bag. Although this can sometimes solve the problem of walking at a vertical height, it sometimes affects the volume of the bag itself due to the lifting point of the track itself, reducing its use efficiency.

And now most of the tracked bags do not use the wrapping method

This will cause bumps in the bag, and it will not be a good combination of the bag and the track

When entering the flat ground, due to the combination of bags and crawlers, the weight of the crawler itself will also cause inconvenience to consumers, especially female consumers.

The box is too heavy, and the friction with the ground will increase

[0008] The function of the crawler luggage invented in the market today is only in the stage of making the luggage run, and it cannot make the crawler device better integrated into the luggage system, and the function is too single

[0009] Sometimes consumers are eager to do something when they are traveling in other places, but because there are valuables in the bag, they must follow the bag with them, resulting in a waste of time and some unnecessary troubles
