AI Technical Summary

Technical Problem

The main support of the existing rowing machine has poor support stability after rotation and folding, and is prone to rotate due to shaking of the pull rope, resulting in unstable support frame.

Method used

A rotating structure of the main bracket is designed, including a rotating shaft, a positioning shaft and a positioning plate. Through the coordination of the positioning groove and the torsion spring on the positioning plate, the main bracket can still be supported stably when shaking under force, and the positioning shaft snaps into and out of the groove to achieve stable rotation of the main bracket.

Benefits of technology

Even when the main bracket is shaken, it can still be used stably, preventing the main bracket from rotating due to tension, and improving the stability of the support bracket.

Abstract

The main support rotating structure comprises a rotating shaft, the bottom of a main support can rotate around the rotating shaft, the main support rotating structure further comprises a positioning shaft and two positioning pieces, the two positioning pieces are arranged on the rotating shaft on the two sides of the main support respectively, and first positioning grooves are formed in the tops of the positioning pieces downwards. The two sides of the main support are further connected with a positioning shaft through supporting pieces respectively, and the positioning shaft can rotate with the connecting positions of the supporting pieces and the main support as the center, so that the two ends of the positioning shaft are clamped into or separated from the first positioning grooves in the two sides. When the positioning shaft is clamped in the first positioning groove, the main support can be effectively prevented from rotating; when the main support is lifted up, the main support can rotate, after the positioning shaft is downwards clamped into the first positioning groove, and when the main support is subjected to obliquely-downward pulling force, the positioning shaft can be clamped deeper and deeper along with the stretching action and cannot be separated from the first positioning groove upwards, the stability is high, and the rowing machine is very suitable for the rowing machine with the main support capable of being pulled to shake.
