AI Technical Summary

Technical Problem

Traditional seesaws cannot adjust the length of the seats on both sides of the support, making it difficult for users with large weight differences to use them smoothly without applying external force. In addition, the seats are prone to vibration when they move suddenly, which poses a safety hazard.

Method used

Design an adjustable seesaw by setting telescopic devices on both sides of the crossbar, using a transmission screw and spring connector to adjust the seat distance, and using springs to cushion and reduce the vibration.

Benefits of technology

It allows people of different weights to use the chair smoothly without applying external force, reducing the vibration sensation when the chair moves suddenly, and improving safety and user experience.

Abstract

This utility model discloses an adjustable-length seesaw with shock absorption function, including a main support and a main crossbar. Both ends of the main crossbar are movably connected to corresponding telescopic devices via corresponding E-shaped connectors. The telescopic device includes a connecting rod, one end of which is connected to the E-shaped connector, and the other end of which is sleeved inside a mounting rod. A transmission screw is provided inside the connecting rod at the end sleeved with the mounting rod, and the end of the transmission screw passes through the outer end of the mounting rod. This utility model, by providing adjustable telescopic devices on both sides of the crossbar, allows the distance between the seat and the support to be adjusted by the transmission screw of the telescopic device, thus accommodating users of different weights without external force. Furthermore, the connector between the crossbar and the telescopic device is equipped with double springs, effectively preventing discomfort caused by sudden lifting or impact.
