The purpose of this utility model is to provide a kind of novel three-wheeled structure trolleys, to solve to mention in above-mentioned background technique
Out the problem of.
To achieve the above object, the utility model provides the following technical solutions: a kind of novel three-wheeled structure trolley, including
Bracket, the bracket is shaped to n font, and the upper end of bracket is equipped with three-stage pull rod, the lower end of the bracket two
Stabilizer blade is equipped with tooth pipe sleeve, and the lower end of the tooth pipe sleeve is set equipped with ratchet, the lower end of the tooth pipe sleeve and in the middle part of ratchet
Have a connecting rod, the small end is socketed with torsional spring, and the connecting rod passes through support sleeve and is rotatablely connected shovel board, the support sleeve it is interior
Portion is equipped with the reversed ratchet opposite with tooth pipe sleeve lower end ratchet, and the upper end of the torsional spring is fixed on tooth pipe sleeve, the lower end of torsional spring
It is fixed on the inner wall of support sleeve, the side of the support sleeve is fixed with connection frame, and the outer end of the connection frame is rotatablely connected triangle
Frame, three ends of the tripod, which are wrapped up, is connected with idler wheel.
Preferably, the maximum rotation angle of the shovel board is 90 degree.
Preferably, the lower end of the connecting rod and be located at support sleeve on the downside of be socketed with gasket.
The technical effect and advantage of the utility model: the novel three-wheeled structure trolley can be real by the way that three idler wheels are arranged
The function of walking on present stair, structure are more simplified easy to use, and folding effect is good, realize idler wheel storage fold, shovel
Plate folds and three-stage pull rod is shunk, and volume after folding is smaller, saves the space for storing the trolley, tripod package connection idler wheel
Can making idler wheel, the service life is longer,.
