Problems solved by technology
[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

Embodiment Construction
[0011] see figure 1 The schematic diagram of the four-wheeled four-step foot and the four-step foot rolling wheel of the hand-held stair walking car series is shown. The car is divided into two parts for storage when not in use. A four-wheel wheel with a diameter of 32 cm is designed, namely figure 1 1 in the four steps, figure 1 All of them are four-step rolling wheels, which use four-step feet to climb and crawl, and utilize four-step foot rolling wheels to roll and walk. The four-step feet and four-step rolling wheels are installed on a folding car body frame, see figure 1 3 in this design is the four-wheel axle center hole of the walking car series of hand held up stairs.

Disclosed is a four-wheel vehicle of hand-held stair walking vehicle series. The four-wheel vehicle can be folded through folding two portions for storing while idle, a wheel, namely a four-step foot and a four-step foot rolling wheel, of 32cm in diameter is designed. The four-step foot is used for climbing, and the four-step foot rolling wheel is used for walking. The four-step foot and the four-step foot rolling wheel are mounted on a folding frame. The four-wheel vehicle can be folded and stand automatically when idle. A 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. A first portion of the folded vehicle adopts the rear line of a rolling wheel, and a second portion of the folded vehicle adopts the connection of the main vehicle and handles. For guaranteeing stability, the diameter of the four-step foot rolling wheel is not larger than 6cm, stability of goods being conveyed on stairs can be guaranteed, and safety of stair climbing is also guaranteed. The four-wheel vehicle is simple in manufacture, low in cost and wide in application range.
Description
Technical field: [0001] The four-wheeled vehicle of the present invention is a series of four-wheeled walking vehicles for stair climbing with hand, which 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 four-wheeled vehicle of the present invention's hand-held stair walking vehicle series just overcomes the deficiencies of the above-mentioned technologies, and...
