Description

Technical Field

[0001] This utility model relates to the technical field of fitness bed accessories, and in particular to a fitness bed locking device for locking the arm pull rope on a fitness bed. Background Technology

[0002] In existing fitness beds, users typically overcome a tension spring between the bed and the frame to move, thus exercising various muscle groups. However, traditional fitness beds lack hand-pulling mechanisms in the front and back areas, hindering arm or leg muscle training. To improve usability, some existing beds use a pull rope that loops around the headboard and is fixed to the bottom for arm pull exercises. However, this method offers only one rope fixing point, making it unsuitable for users with different arm spans. Furthermore, to increase intensity, the rope ends are often locked, preventing independent adjustment of the left and right lengths, thus impacting the user experience.

[0003] In view of the shortcomings of existing technologies, the urgent technical problem to be solved is: how to design a set of locking devices for fitness beds through technological improvements, which can achieve rapid adjustment of the arm pull ropes through manual control, and can be stably locked and not loosened after adjustment, with the aim of eliminating the functional drawbacks of existing fitness bed technologies.
