Folding roller skating learning assistor

Abstract

The invention provides a folding roller skating learning assistor. The folding roller skating learning assistor is composed of a metal handle, supports, folding mechanisms and universal castors. The metal handle is of a circular ring structure and is connected with the upper ends of the supports through the folding mechanisms; each support is composed of an inner steel pipe, an outer steel pipe and a height adjusting mechanism, wherein the diameter of the outer steel pipe is larger than that of the inner steel pipe, and the inner steel pipe and the outer steel pipe are fixed through a press type round-head-shaped metal fastener to adjust the height. The universal castors are connected with nuts welded to the bottom ends of the inner steel pipes of the supports through fixed threaded rods, and a gravity brake device is arranged on each universal castor. By adopting the folding structure, the roller skating learning assistor is convenient to unfold and fold, convenient and fast to use and higher in safety and saves space.

Description

technical field [0001] The invention relates to a roller skating learning aid, in particular to a folding roller skating learning aid. Background technique [0002] With the improvement of people's living standards, the requirements for the quality of life are getting higher and higher.

Problems solved by technology

At the same time, the device is only equipped with universal wheels, and there is no brake device for the universal wheels. During use, the speed control problem caused by inertia cannot be well controlled, and the learning aid device cannot be braked in time, which is not very good. Play the role of protecting roller skating learners, increasing the possibility of learners being injured

[0005] The application number is 201420761211.2, which discloses an assembled roller skating learning aid, which consists of four parts: metal handrails, supports, protective rings and universal casters. The connection between the parts is assembled by mortise and tenon. , time-consuming and labor-intensive assembly, extremely inconvenient

At the same time, there is no brake device on the universal wheel, so the safety problems caused by inertia cannot be well controlled during use, and the learning aid device cannot be braked in time, so it cannot protect roller skating learners well. effect, increasing the likelihood of learner injury
