Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

As shown in Figures 1 and 2, a small trolley for climbing stairs includes a handle bar 1, a vehicle frame 2, a rope adjuster 3, a pole 4, a wheel 5, a pole 6, an elastic member I7 and an elastic member II8 .

Wherein the vehicle frame 2 is the main frame structure, and the materials to be transported can be placed on the vehicle frame. The vehicle frame 2 includes two vehicle frame longitudinal bars. A gear rod is welded between the longitudinal rods, and the gear rod is located at the front end of the longitudinal rod of the vehicle frame, and is used to block the materials and prevent the materials from falling.

The rear end of the vehicle frame 2 is provided with a handle bar 1, the handle bar 1 is sleeved on the vehicle frame 2, the handle bar 1 and the vehicle frame 2 are provided with a card hole, and a bayonet pin is arranged in the card hole, and the handle bar is realized by using the card pin. The rod is fixed on the frame, and the length of the handle rod can be adjusted as needed, so that the front end of the frame can be lifted more effortlessly. The front end of vehicle frame 2 is provided with wheel 5, and wheel can walk on the step, is used for the movement of trolley.

The middle part of vehicle frame 2 is welded with cover seat, and the upper end of cover seat and strut 4 is hinged, can realize that vehicle frame rotates relative to support rod, realizes wheel lifting one-order step. The lower end of the pole 4 is connected to one end of the stay rope, and the other end of the stay rope is connected to the rope adjuster 3. The rope adjuster 3 is set at the rear of the frame 2, and the rope adjuster 3 is detachable from the frame 2 through bolts. Connect, unscrew the bolt, the adjustment of the position of the rope adjuster 3 on the vehicle frame 2 can be realized. Through the restriction of the stay rope, the maximum included angle between the strut and the vehicle frame is limited to 90°, which can prevent the vehicle frame from falling backward and avoid danger caused by the backward movement of the vehicle frame.

The front side of the strut 4 is hinged with the elastic member 17, and the elastic member 17 is hinged with an end plate of the support plate 6, so as to realize the elastic support limit of the strut to the support plate. The front part of the vehicle frame 2 is hinged with the elastic member II8, and the elastic member II8 is hinged with the other end plate of the brace plate 6, so as to realize the elastic support limit of the vehicle frame to the brace plate. The support plate is L-shaped, and is used to fit the protruding right angle of the step, and utilizes the elastic element I and the elastic element II to damp and buffer the vehicle frame.

As shown in Figure 3, when the trolley is performing ladder climbing operations, the pole is used as the support base, and the support plate is clamped at the right angle of adjustment. Press down the handlebar to lift the front end of the frame. Since the handlebar is longer, the operation is less labor-intensive. At this time, the elastic member I is not deformed, and the elastic member II is restored, and the upward elastic force of the elastic member II can also make it easier to lift the front end of the vehicle frame. The raised height of the frame should be appropriate to avoid high potential energy of the frame and materials. Due to the L-shaped structure of the brace and the elastic member, the brace can be fixed at a right angle without moving. At this time, the trolley frame is pushed forward to make the pole tilt, and the gravity makes the trolley automatically fall forward, and the elastic parts I and II are compressed and deformed, which continuously provides upward cushioning force for the trolley, effectively preventing the wheels from being damaged. Due to the influence of gravity, it falls directly on the previous step, causing a large vibration of the frame and the problem that the material is easy to fall. After the wheel falls to the last step, the rear end of the frame is lifted, and the trolley is pushed to walk.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of the present invention. within the scope of protection.
