Description

Technical Field

[0001] The utility model relates to the technical field of portable vehicles, in particular to a portable vehicle for walking. Background Art

[0002] Hiking is the most typical and common outdoor sport. Long-distance hiking requires carrying a large amount of equipment and supplies, so a carrying vehicle is needed to facilitate carrying supplies.

[0003] Existing portable vehicles are usually of two-wheeled structure. When the handlebars of the vehicle stop being pressed downward or upward, one of the two ends of the vehicle tilts downward and touches the ground, which not only causes wear on the front and rear ends of the vehicle, but also requires the vehicle handlebars to be pressed at all times, which is extremely inconvenient. In addition, the handlebars on both sides of the existing portable vehicles are fixed in height and difficult to adjust to an appropriate height for use. For this reason, we propose a walking portable vehicle. Utility Model Content

When a walking user uses the utility model, the threaded lifting rod 17 is driven to rotate by the wheel 18, and the threaded lifting rod 17 rotates on the inner wall of the internal thread lifting sleeve 19. The internal thread lifting sleeve 19 is height-adjusted inside the lifting frame 16, which makes it easy to adjust the height of the two push-pull rods 20, and it is convenient to adjust the two push-pull rods 20 to an appropriate height, which is beneficial to improving the portability of the utility model. The user pulls the utility model through the rubber handle 21 for walking. When the user is tired or going uphill, the battery 6 provided on the fixed beam 1 starts the electric wheel 2 to rotate, which can provide power for the vehicle pulled by the user and save effort for the user. At the same time, the auxiliary wheels 4 installed at the bottom of the first support plate 3 on both sides of the fixed beam 1 can avoid wear and tear on the front and rear ends of the vehicle from contacting the ground. There is no need to press the push-pull rod 20, which is easy to use.
