Connecting rod locking guardrail structure

Abstract

The invention relates to a connecting rod locking guardrail structure which comprises a first L-shaped force arm, a second L-shaped force arm, a first fixing seat and a second fixing seat. A rotating shaft is arranged in the middle of the first force arm and provided with a switch hook, and the front end of the switch hook is an olecranon hook part. A first connecting shaft is arranged on the upper portion of the first force arm, a switch handle is arranged on the first connecting shaft, the upper portion of the switch handle is rotationally connected with the first connecting shaft, and a handle hinge plate is further arranged on the switch handle. The handle hinge plate is connected with the rear end of the switch hook through a connecting rod; two ends of the connecting rod are respectively hinged with the handle hinge plate and the switch hook; a locking shaft matched with the olecranon hook part is arranged in the middle of the second force arm; the upper end and the lower end of the first force arm are hinged to the lower portion of the second fixing seat and the lower portion of the first fixing seat respectively, and the upper end and the lower end of the second force arm are hinged to the upper portion of the second fixing seat and the upper portion of the first fixing seat respectively. The connecting rod locking guardrail structure is convenient to use, has a self-locking function, and is smooth in unlocking and low in noise.

Description

technical field [0001] The invention belongs to the technical field of medical beds, and in particular relates to a connecting rod locking guardrail structure.
