A wheel missing anti-skid and anti-fall stair climbing trolley

Abstract

The invention discloses a wheel missing anti-skid and anti-fall climbing trolley, which comprises a main frame, a bottom frame is welded to the lower end of the main frame, a back frame is welded to the left side of the bottom frame, the main frame, the bottom frame and A storage basket is welded together on the back frame, an anti-fall protection mechanism is installed in the bottom frame, a plurality of brackets are welded symmetrically on both sides of the main frame, and a plurality of brackets located on one side of the main frame among the plurality of brackets Rotating sleeves are fixedly installed on each of the rotating sleeves, and a rotating shaft is rotatably inserted in each of the rotating sleeves, and two arc-missing wheels are symmetrically sleeved on both ends of each of the rotating shafts. The structure design of the present invention is ingenious, through the lack of arc wheel to achieve the effect of halfway rest anti-skid, anti-backward, braking and parking, through the anti-fall protection mechanism to achieve the effect of immediately popping up the protective frame to support and protect the car from overturning and falling when the fall is overturned, which increases The safety of the trolley, and the function that the trolley can stop and rest is added.

Description

technical field [0001] The invention relates to the technical field of stair climbing vehicles, in particular to a wheel missing anti-slip and anti-falling stair climbing trolley. Background technique [0002] With the improvement of living standards, more and more young urban residents or rural residents choose to buy new houses to live in. However, the elderly in the family are generally less willing to move into new communities, and will still stay in old communities or rural areas. A common situation in the community is that very few small high-rise buildings have elevators, and most small high-rise buildings use stairs to go up and down, which brings great inconvenience to the elderly. The elderly live at home and need to buy vegetables every day , buying daily necessities, etc. like to carry a basket or a small trailer, which is convenient for storing a large number of purchased goods, and does not need to be carried upstairs by hand, so climbing stairs and getting off...

[0002] With the improvement of living standards, more and more young urban residents or rural residents choose to buy new houses to live in. However, the elderly in the family are generally less willing to move into new communities, and will still stay in old communities or rural areas. A common situation in the community is that very few small high-rise buildings have elevators, and most small high-rise buildings use stairs to go up and down, which brings great inconvenience to the elderly. The elderly live at home and need to buy vegetables every day , buying daily necessities, etc. like to carry a basket or a small trailer, which is convenient for placing a large number of purchased goods, and does not need to be carried upstairs, so climbing stairs and getting off the car is more and more popular among the elderly

[0003] However, most of the current stair-climbing trolleys are in a single-wheel structure. When climbing stairs, it is difficult to roll upwards, and it is particularly easy to slip, causing the trolley to fall from the upper stairs to the bottom platform. People in the rear cause injuries, and the latest one-sided three-wheel distribution is equidistant in a circle, which is more stable when climbing stairs, but this structure does not have a middle rest (stopping for a rest, the car will fall and retreat due to its own weight, The physical strength of the elderly is declining, and most of them need to rest several times in the middle of climbing stairs), and in the case of heavy objects, they are easy to turn backwards, resulting in dangerous situations. There is no good solution in the prior art
