fig. 2 is a schematic structural diagram (sectional view) of the present invention.
Detailed Description
In order to make the technical problem, technical solution and advantageous effects solved by the present invention more clearly understood, the following description is given in conjunction with the accompanying drawings and embodiments to further explain the present invention in detail. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1-2, the present application provides a rotatable armrest according to an embodiment, including an armrest body 1, a connecting shaft 2, a limiting member 3, and an elastic member 4, where the limiting member 3 is fixedly disposed inside the connecting shaft 2, the elastic member 4 is disposed on the limiting member 3 so that the elastic member 4 can rotate relative to the limiting member 3, and the armrest body 1 passes through one end of the connecting shaft 2 and then passes through the limiting member 3 to be connected to the elastic member 4, so that the armrest body 1 can move up and down along an axial direction of the connecting shaft 2 and can be reset by the elastic member 4 after rotating;
the handrail device is characterized by further comprising at least one clamping position 5 arranged on the connecting shaft 2 and a positioning piece 6 arranged on the handrail body 1 and matched with the clamping position 5 for positioning after the handrail body 1 is rotated and reset.
In order to realize the above purpose, the utility model discloses a handrail body, the connecting axle, locating part and elastic component, fix the locating part inside the connecting axle, so that elastic component and locating part butt, consequently elastic component can be rotatory or compress self relatively and make handrail body move up, it breaks away from the screens stroke to shift up the in-process setting element, consequently, this physical stamina of handrail carries out rotation regulation, adjust and fix a position on the screens that drives handrail body's setting element entering correspondence through elastic component's the setting element that resets behind the required angle of user, thereby medical personnel no longer need bow to squat down and just can rotate the handrail to the position that needs, it can carry out rotation regulation directly to mention the handrail in the upside.
In this embodiment, it is preferable, the elastic component 4 includes a bolt 41, a first gasket 42 and a spring 43, the bolt 41 passes the first gasket 42, the spring 43 and the locating part 3 with the handrail body 1 is connected, so that when the handrail body 1 moves upwards, the spring 43 compresses the spring 43, the handrail body 1 is driven to move downwards after recovering, the locating part is a second gasket, the second gasket is fixed inside the connecting shaft, the bolt passes the first gasket, the second gasket and the spring and is in threaded connection with the handrail body, after the handrail body is lifted by a user, the bolt and the first gasket are driven to ascend, so that the spring is compressed, the positioning part can be rotationally adjusted after being separated from the clamping position, and after the angle is adjusted to a required angle, the spring resets, so that the first gasket and the bolt descend to drive the handrail body to clamp the corresponding position.
