Shifting-type stepless limit guardrail opening and closing structure

Abstract

The invention provides a shifting-type stepless limit guardrail opening and closing structure. The guardrail opening and closing structure comprises a hollow fixed sleeve which is provided with a guardrail installation insertion hole penetrating through the top and the bottom of the hollow fixed sleeve; a fixed seat is arranged at the outer side of the hollow fixed sleeve, a linear sliding slot extending to two ends is formed in the side face of the fixed seat, an extension line of the linear sliding slot penetrates through the hollow fixed sleeve, a sliding block is arranged in the linear sliding slot in a matched mode, and a clamping plate is arranged at the end, close to the hollow fixed sleeve, of the sliding block; and an opening is formed in the position, corresponding to the clamping plate, on the side wall of the hollow fixed sleeve, and the clamping plate moves in a straight line along with the sliding block to stretch into or retreat from the hollow fixed sleeve through the opening. According to the opening and closing structure, the clamping plate is made to slide leftwards to block the lower end of the opening of a guardrail frame, and the whole guardrail frame cannot be lifted up and then cannot rotate; and reversely, the clamping plate is made to slide rightwards to move away from the top of the lower end of the opening of the guardrail frame, then the guardrail frame can be lifted up and rotate, and the opening and closing functions through guardrail rotation are achieved.

Description

Technical field [0001] The invention relates to the field of medical equipment, and more specifically to a toggle type non-limit position guardrail switch structure. Background technique [0002] At present, the medical beds are equipped with guardrails, and the guardrails are mainly composed of a guardrail frame 1 and a railing 4 spaced between the guardrail frames. In the common installation method, multiple guardrails are required to be enclosed in sequence around the hospital bed. This requires that the guardrails can be installed successively, and at the same time, two adjacent guardrails can be opened to form a switch door, that is, a certain guardrail can be around. The mounting rod 2 rotates. In this structure, a hollow mounting rod 2 is generally fixed vertically on the side of the guardrail, and one side of the guardrail frame 1 is set to be broken, that is, the upper and lower ends of the side guardrail frame 1 It can be rotated and installed to the upper and lower e...

Problems solved by technology

In this way, it is easy to cause misoperation during use, so we urgently need to design a switch that can limit the guardrail. When needed, the guardrail can be lifted and rotated. When not needed, the guardrail remains locked and cannot be rotated.
