Disclosed is a push-pull seven-wheel vehicle of hand-held stair walking vehicle series. The push-pull seven-wheel vehicle comprises a cushion frame, a seven-step foot, a seven-step foot rolling wheel, a brake pad, a frame, cushions, and foldable handles. The push-pull seven-wheel vehicle is characterized in that a wheel, namely the seven-step foot and the seven-step foot rolling wheel, of 65cm is designed. The seven-step foot is used for climbing, and the seven-step foot rolling wheel is used for walking. The seven-step foot and the seven-step foot rolling wheel are mounted on a folding frame. Cushions are designed on the devices of the vehicle body and wheels. The frame of the first folded vehicle adopts the rear line of rolling wheels as the folding line, a second portion adopts the connection of the main vehicle body and handles as the folding line, the rear of a wheel protecting box of the vehicle can be used for pushing, and the brake pad with a braking function is arranged on a vehicle shaft, so that the vehicle is prevented from returning when goods are conveyed on stairs. Cushion devices are arranged between the vehicle shaft and the vehicle frame, so that stairs can be climbed conveniently and simply; for guaranteeing stability, the diameter of the seven-step foot rolling wheel is not larger than 6cm, stability of goods being conveyed on stairs can be guaranteed, and the vehicle can move with braking on flat ground. Manufacture is simple, and application range is broad.
Description
Technical field: [0001] The push-and-pull seven-wheeled vehicle series of hand-supported stair-climbing walking vehicles of the present invention relates to the current problem of carrying up stairs Background technique: [0002] The problem of stair-carrying in the current technology is very important. In general stair-walking vehicles, there is a patented product that is a tripod with three wheels. It is installed at the back of the car. Be sure, when going up the stairs, the goods are pressed in front of the wheels, and one-half of the weight of the goods is carried by the hands of the people. In addition, people have to pull the carts up the stairs, so it is not necessary to move them manually. Such products are very helpful for solving labor The usefulness is too small. Invention content: [0003] The push-pull seven-wheeled vehicle of the present invention's hand-supported stair walking vehicle series just overcomes the deficiencies of the above-mentioned technologi...
