Automatic telescopic device of multifunctional child scooter

Abstract

The invention provides an automatic telescopic device of a multifunctional child scooter and belongs to the technical field of child toys. The automatic telescopic device solves the problems that an existing scooter is too complex in structure and single in use function. The automatic telescopic device of the multifunctional child scooter is mainly characterized in that a round connecting board isfixedly arranged in an upper round pipe, an air cylinder is arranged in a lower round pipe, an air cylinder body of the air cylinder is fixedly connected to the inner portion of the lower round pipe,an air cylinder rod of the air cylinder extends into the upper round pipe, the extend-in end of the air cylinder rod is fixedly connected to the round connecting board, an inward-retracting opening ring turned inside from outside is arranged in the position of an upper pipe opening of the lower round pipe, an outward-retracting opening ring turned outside from inside is arranged in the position of a lower pipe opening of the upper round pipe, and the outward-retracting opening ring is located in the lower round pipe and clamped on the inward-retracting opening ring. The automatic telescopic device is simple and ingenious in structural design, safe and beautiful, the height of the upper round pipe and the height of the lower round pipe can be adjusted, and use is convenient.

Description

technical field [0001] The invention belongs to the technical field of children's toys, and relates to an automatic telescopic device for a multifunctional children's slide car. Background technique [0002] With the improvement of living standards and the development of express delivery in social industries, the configuration requirements required by industry are also getting higher and higher. Plastic products have generally entered people's lives, and plastic products are mainly injection molded by injection molding machines. Injection molding The injection molding machine is the most used processing machinery in the plastics processing industry. Not only a large number of products can be directly produced by the injection molding machine, but also the key equipment for the injection stretch blowing process. China has become the largest country in the production of plastic machine parts in the world. The reasons for promoting the development of China's injection molding...

Problems solved by technology

[0004] Children's scooters are a fashionable sports and leisure tool nowadays; deeply loved by children, children's scooters are suitable for children aged 3-5 to play; children's scooters are another popular after scooters became popular in our country a few years ago. Fitness toys for children's sports; children's slides on the existing market have a relatively single structure and monotonous functions, such as a slide in the Chinese patent: "CN205469551 U". The specific structure of the slide is: it includes a frame, A control lever connected to the vehicle frame, a front wheel pivotally arranged on the control lever, a brake device arranged on the control lever, a pedal set arranged on both sides of the vehicle frame, and a pedal set arranged on both sides of the vehicle frame A seat on the frame, and at least one rear wheel arranged on the vehicle frame; wherein, two handles are formed on the control lever, and the control lever is used to control the control lever to drive the direction of travel of the front wheel, and the braking device has a A controller arranged on a handle, a brake part arranged on the front wheel, and a brake wire connecting the brake part and the controller: the characteristic is that a chute is opened on the bottom surface of the vehicle frame , the vehicle frame is provided with a positioning piece, a folding device is provided between the vehicle frame and the control rod, and the folding device has a body fixed on the control rod, a body pivoted on the body and extending An actuator that slides in the chute, and a latching piece for the frame to be positioned on the body, wherein the positioning piece of the frame is latched on the latching piece to form The vehicle frame and the control rod are in the extended use state; a setting piece is provided between the vehicle frame and the actuator so that the actuator is positioned on the vehicle frame; the rear wheels are two, respectively pivoted On both sides of the frame; the frame is provided with a protective piece, and the protective piece embeds the positioning piece embedded in the locking piece to prevent the positioning piece from detaching from the locking piece. ; Also provided with a wheel hub driving device, the wheel hub driving device has a power source located in the body, a control member located on the other handle and connected to the power source, and a control member located on the front wheel And the driving member that is output by the power source to drive the front wheel to rotate

In the above-mentioned pulley structure, the structure is too complicated; the function is too monotonous, and the control lever of the pulley cannot be adjusted, so for those children with slightly longer legs, it is more difficult to slide
