Embodiment 1

[0028] refer to Figure 1-3 , an armrest locking structure, including an adjustment cylinder 1 and a rotating shaft 2 that is rotatably arranged at both ends of the adjustment cylinder 1, and a cylinder-shaped adjustment cavity 11 arranged around the rotation shaft 2 is opened in the adjustment cylinder 1 on the outside of the rotation shaft 2, The bottom of the rotating shaft 2 is symmetrically opened with an arc-shaped limiting groove 21 that communicates with the adjusting cavity 11 and is gradually concave toward the inner side of the rotating shaft 2. The adjusting cavity 11 is provided with a one-way limiting locking and abutting against the limiting groove 21 There is a locking mechanism inside, and a locking mechanism that can move vertically to abut against and limit the locking mechanism is provided on the top of the adjustment cylinder 1 .

[0029] in,

[0030] The locking mechanism includes an arc-shaped compression spring 3 arranged in the adjustment chamber 11, ...

Embodiment 2

[0038] refer to figure 1 and Figure 4 , a handrail using the above-mentioned locking structure, including a guardrail body 9, the two ends of the guardrail body 9 are respectively fixed on the two ends of the rotating shaft 2, and at the same time, the adjustment cylinder 1 is fixed on the nursing bed frame 0.

[0039] In this application, the structures and connection relationships that are not described in detail are all prior art, and their structures and principles are already known technologies, and will not be repeated here.

Abstract

The invention discloses an armrest locking structure and an armrest structure thereof, which comprises an adjusting cylinder and rotating shafts rotationally arranged on the two end sides of the adjusting cylinder, and a cylindrical adjusting cavity surrounding the rotating shafts is formed in the position, on the outer sides of the rotating shafts, in the adjusting cylinder; arc-shaped limiting grooves which are communicated with the adjusting cavity and gradually concave inwards towards the inner side of the rotating shaft are symmetrically formed in the bottom of the rotating shaft, and a locking mechanism which can be limited and locked in a one-way mode and abut against the inner sides of the limiting grooves is arranged in the adjusting cavity. A locking mechanism which can vertically move and is used for abutting against and limiting the locking mechanism is arranged at the top of the adjusting cylinder. The armrest locking structure has a good locking effect on the rotating shafts of the guardrails, so that the guardrails are not easy to open from the inner side of a bed by a patient, and the safety is relatively high; the locking mechanism which is lifted upwards is arranged to be matched with the locking mechanism, so that external medical personnel can rotate and unfold the guardrail conveniently.

Description

technical field [0001] The invention relates to the technical field of nursing beds, in particular to an armrest locking structure with high safety and easy to be opened from the outside and an armrest structure thereof. Background technique [0002] At present, most of the beds used in wards and homes for patients with mobility issues are ordinary beds, and a simple structure consisting of a bed surface and bed legs. The nursing bed can tilt and lift the bed board, and the patient can sit up or lie down. [0003] During actual use, the armrest should not only protect the patient on the bed, but also be difficult to open from the bed; at the same time, it should be easy to deploy from the outside to facilitate the nursing staff to transfer the patient or perform other nursing operations. [0004] At present, most of the armrests are foldable, so it is easy for the patient to accidentally touch and squeeze the armrest, causing the armrest to fold itself, which may cause the ...
