Connecting rod coaxial safety protection type quick-learnt scooter

Abstract

The invention belongs to the field of sports appliances and particularly relates to a connecting rod coaxial safety protection type quick-learnt scooter. The connecting rod coaxial safety protection type quick-learnt scooter comprises two pedals. The lower portion of each pedal is connected with a front guide wheel and a rear driving wheel, and the front guide wheel and the rear driving wheel are both hinged to the bottom of the pedal. A connecting rod is connected between the front ends of the two pedals. The two ends of the connecting rod are connected to wheel frames of the front guide wheels, the connecting rod is fixed to the wheel frames, the middle of the connecting rod is thick while the two ends are thin, the thick end and the thin end are connected through a chamfer, and the thin end of the connecting rod is provided with a thread. The thin end of the connecting rod sequentially penetrates one side of the wheel frame, the front guide wheel and the other side of the wheel frame, and a fixed nut is tightened at the position of the thread at the thin end of the connecting rod, so that the connecting end and the wheel frame are tightly connected together. The fixed nut is sleeved with a protective sleeve. The mode of connecting the connecting rod and the wheel frame of the scooter is more flexible, a manufacturing process is simpler, and the scooter is more attractive.

Description

Technical field [0001] The invention belongs to the field of sports equipment, and particularly relates to a sliding tool. Background technique [0002] Sliding on a smooth ground is a sport that the common people prefer. It is not only a physical exercise, but also a refreshing artistic activity. Glide on the ground requires special tools, which generally use roller skates or vitality boards. Roller skates are composed of two separate pedals and wheels under the pedals. Roller skates for roller skating have only four wheels each. The vitality board consists of a pedal and two wheels under the pedal. The sliding tools in the prior art have the following shortcomings: when roller skating, roller skates are put on and tied with shoelaces, and the foot applies forward force to slide on the ice. For beginners, it is difficult to grasp the balance and fall easily. When using the vitality board, a person steps on the pedal to slide sideways, and the person's orientation is perpendi...

The applicant applied for a fast-learning scooter in 2011. This scooter overcomes the problem that learning to roll is difficult. In this application, the connecting rod is welded on the wheel frame, so the setting has the following disadvantages: 1. It is technically difficult to achieve a tight connection between the connecting rod and the wheel frame within the range of the cross-sectional size of the connecting rod; 2. Because the two ends of the connecting rod are respectively connected to the left and right wheel frames, the position of the welding point on the wheel frame must Keep it coaxial, otherwise it will easily cause the scooter to be unbalanced and difficult to slide; 3. When the connecting rod and the wheel frame are welded together, marks will inevitably be left on the end surface of the wheel frame, which will affect the appearance of the product
