Description

Technical Field

[0001] The utility model belongs to the technical field of transportation tools, and in particular relates to a portable scooter. Background Art

[0002] A scooter is a small platform with two or more wheels that the user pushes on the ground to move forward. The most common scooters today have two wheels and are mainly made of aluminum for lightness. There are also scooters with 3 or 4 wheels, some are made of plastic, some are larger, some are not foldable, etc. And some scooters made for adults for acrobatics are a bit like old-fashioned bicycles with a large front wheel and a small back wheel.

[0003] Since the handlebar of a conventional scooter can still rotate after being folded, the body of the scooter rotates when the handlebar is held to carry it, so that the center of the scooter is easily changed when it is carried, and it is difficult to ensure stability when carried, resulting in the problem that the conventional scooter is not convenient to carry.

[0004] For this reason, we propose a portable scooter to solve the above problems. Utility Model Content

[0005] The utility model aims to solve the problem that conventional scooters are inconvenient to carry, and provides a portable scooter.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A portable scooter comprises a tension spring, a body, a steering frame and a plug, wherein the steering frame is rotatably mounted on the front of the body, the plug is slidably mounted on the front of the body, the tension spring is connected between the body and the plug, and the plug is buckled and matched with the steering frame. The plug is inserted on the steering frame to prevent the steering frame from unfolding and rotating, thereby increasing the stability of the folded state of the steering frame and preventing the body and the steering frame from twisting back and forth after being folded, thereby reducing the difficulty of carrying.

[0008] Preferably, the vehicle body comprises a chassis, a brake cover, a first roller, a guide seat and a restraining sleeve, the brake cover is rotatably mounted on the rear of the chassis, a return spring is connected between the brake cover and the chassis, the first roller is rotatably connected to the rear of the chassis, and the guide seat and the restraining sleeve are fixedly connected to the front of the chassis. Stepping down on the brake cover causes the brake cover to squeeze the first roller, thereby increasing the rotation resistance of the first roller and facilitating stepping on the brake.

[0009] Preferably, the vehicle body further comprises a traction roller, which is rotatably connected to the front of the chassis. After the device is folded, the traction roller is dragged along the ground by holding the steering frame, so that the traction roller rolls along the ground, which is convenient for dragging in a flat and crowded shopping mall.

[0010] Preferably, the steering frame comprises a frame body, a U-shaped frame, a handle, a swing frame and a second roller, the frame body is rotatably connected to the upper part of the swing frame, the second roller is rotatably mounted on the front part of the frame body, and the U-shaped frame is fixedly connected between the frame body and the handle. After the bolt is pulled open, the bolt is disengaged from the second roller, the steering frame is unfolded, and then the bolt is inserted into the swing frame to lock the swing frame, so as to maintain the unfolded state of the steering frame.

[0011] Preferably, the steering frame further comprises a traction handle, which is fixedly connected to the grip. After the device is folded, the traction handle is held by hand to drag the scooter along the ground, so that the traction rollers touch the ground and roll, which is convenient and labor-saving to carry the folded device.

[0012] Preferably, the plug includes a plug body and a pull button, and the pull button is fixedly connected to the outer end of the plug body. The pull button is squeezed and pulled outward, so that the pull button overcomes the tension of the tension spring and drives the plug body to slide outward along the guide seat until the plug body is separated from the swing frame or the second roller, unlocking the direction frame, thereby facilitating the maintenance of the open or closed state.

[0013] Preferably, the bolt further comprises a guide block, which is fixedly connected to one end of the bolt body facing away from the pull button. The guide block is used to guide the bolt body to be inserted into the swing frame or the second roller, thereby improving the convenience of bolt locking.

[0014] In summary, the technical effects and advantages of the utility model are as follows:

[0015] 1. Use the plug to insert on the steering frame to prevent the steering frame from unfolding and rotating, increase the stability of the folded state of the steering frame, and prevent the body and the steering frame from twisting back and forth after folding, thereby reducing the difficulty of carrying.

[0016] 2. After folding the device, hold the steering frame and drag the traction roller along the ground to make the traction roller roll along the ground, which is convenient for dragging in a flat and crowded shopping mall.

[0017] 3. After pulling the bolt apart, disengage the bolt from the second roller, unfold the steering frame, and then insert the bolt into the swing frame to lock the swing frame to maintain the unfolded state of the steering frame.

[0018] 4. After the device is folded, hold the traction handle and drag the scooter along the ground so that the traction rollers touch the ground and roll, which is convenient and labor-saving to carry the folded device.

[0019] 5. Pull the pull button outward to make it overcome the tension of the tension spring and drive the bolt body to slide outward along the guide seat until the bolt body is separated from the swing frame or the second roller, unlocking the direction frame, thereby facilitating the maintenance of the expanded or closed state.
