AI Technical Summary

Technical Problem

The existing seatable and lying structure used for rhythms can easily lead to excessive stress on the shaft, resulting in deformation and lag, and may even cause accidents.

Method used

A structure including a base, a support plate, a rotary rod, a connecting block, a retainer plate, a bearing, a baffle and a self-locking rotary knob are designed. The rotation of the retainer rod drives horizontal movement of the support rod to ensure that the retainer plate can contact the base in parallel when in use, thereby dispersing the torque and avoiding deformation and rotation of the rotary shaft.

Benefits of technology

It effectively avoids deformation and rotation of the rotating rod and rotating rod caused by the recess plate when it is subjected to stress, improves safety and ensures the stable use of the rhythm.

Abstract

The utility model relates to the technical field of sitting and lying of a law mover, and discloses a sitting and lying structure for the law mover, which comprises a base, a support plate is arranged in the middle above the base, a rotating rod is movably arranged on the support plate in a penetrating manner, connecting blocks are arranged on the rotating rod on two sides of the support plate, and the other ends of the two connecting blocks are connected with a backup plate. Bearings are arranged at the two ends of the rotating rod, and baffles are arranged at the opposite ends of the two bearings. According to the utility model, when the first connecting plate rotates, the first connecting plate can respectively drive the first movable rods to rotate, so that the first movable rods can push the first supporting rods to horizontally move on the base until the backup plate is parallel to the base, and the first supporting rods can be in contact with the backup plate; therefore, supporting force can be provided for the backup plate, the situation that the rotating rod deforms and rotates due to the fact that the backup plate bears large force is avoided to a certain degree, and the device is practical and suitable for wide application and popularization.
