AI Technical Summary
The existing fixed and movable seats are not conducive to reinforcement, which affects the splicing efficiency and may reduce the overall structural stability, posing a safety hazard.
The design incorporates reinforcement components, including a fixed cylinder, an extension cylinder, a movable seat, and reinforcement elements. The structural design of slots, blocks, inserts, and reinforcement ears enhances the stability of the connection between the fixed seat and the movable seat.
It improves the efficiency of splicing fixed and movable seats and the stability of the overall structure, enhances safety, prevents relative displacement, and meets the installation needs of different construction scenarios.
