Technical Field
The utility model belongs to the technical field of medical instrument, especially, relate to a medical chair braced frame's of accompanying and attending to connected node.
Background
At present, because hospital beds in various cities are tense, families nursing patients are difficult to get vacant hospital beds to lie down for rest and sleep. In order to relieve the fatigue of caregivers and enable the caregivers to more comfortably lie and sleep while nursing patients, a dual-purpose chair for sitting and lying with a smaller floor space has been developed. The often be equipped with the chair of accompanying and attending to that supplies the patient of accompanying and attending to the person rest usefulness in the ward, for the convenience of accompanying and attending to the person and using, common chair of accompanying and attending to possesses folding function mostly, can expand into the bed through folding the chair of accompanying and attending to and supply the person of accompanying and attending to lie, realizes that a thing is dual-purpose.
The accompanying chair in the prior art is structurally composed of a chair leg support 5, a head frame 1, a back frame 2, a seat frame 4 and a connecting piece, wherein the head frame 1, the back frame 2 and the seat frame 4 are all of rectangular frame structures, one side edges of the head frame 1 and the back frame 2 are hinged through a pin shaft assembly 3, the pin shaft assembly 3 comprises a pin shaft and a shaft sleeve, the pin shaft and the shaft sleeve are respectively welded on the head frame and the back frame, then the head frame and the back frame are connected through splicing, the other side edge of the back frame is hinged with one side edge of the seat frame, a movable supporting mechanism is arranged at the bottom of the seat frame, when the accompanying chair is folded, the back frame and the head frame are both in a vertical state and are close to each other, when the accompanying chair is unfolded, the head frame, the back frame and the seat frame are all in a horizontal state, cushions are respectively arranged in the head frame, the back frame and the seat frame, the user can lie on the supporting surface formed by connecting the head frame, the back frame and the seat frame.
When a user lies on the accompanying chair, the back frame is a main bearing part, and at the moment, the pin shaft assembly is also subjected to a large acting force, so that the pin shaft is easily bent and deformed, after the pin shaft is deformed, on one hand, the folding and unfolding of the accompanying chair are affected, and most importantly, the use insecurity is caused; therefore, the pin shaft assemblies need to be replaced, the pin shaft assemblies are cut from the head frame and the back frame firstly, and then new pin shaft assemblies are welded to the head frame and the back frame again, so that the operation is very troublesome and the cost is high, and the wall thicknesses of the head frame and the back frame are thin, so that the head frame and the back frame are easily damaged in the welding process.
SUMMERY OF THE UTILITY MODEL
In order to solve the problems existing in the prior art, the utility model aims to provide a medical accompanying chair braced frame's connected node, this connected node dismantles conveniently, is convenient for change, has higher intensity moreover.
In order to realize the purpose of the utility model, the utility model adopts the following technical scheme:
a connecting node of a supporting frame of a medical accompanying chair comprises a head frame, a back frame, two supporting pieces, bolts and nuts, wherein each supporting piece is composed of a connecting plate and a fixing part which are of an integral structure, each fixing part comprises two fixing plates which are parallel up and down, the two fixing plates are respectively positioned on the upper surface and the lower surface of one end of each connecting plate, and a through hole is formed in the front end face of the other end of each connecting plate; two fixed plates on one support piece are welded on the head frame and the head frame is positioned between the two fixed plates, two fixed plates on the other support piece are welded on the back frame and the back frame is positioned between the two fixed plates, the connecting plates on the two support pieces are corresponding, and the bolt penetrates through the through holes on the two connecting plates and then is screwed with the nut.
Furthermore, the head frame is connected with the back frame through a plurality of groups of supporting components, and each group of supporting components comprises two supporting pieces connected with each other.
Due to the adoption of the technical scheme, the utility model discloses following beneficial effect has:
the head frame and the back frame are connected through the two supporting pieces, the bolts and the nuts, so that the connecting structure is simple and reliable, and if the bolts deform under stress, only the bolts need to be replaced without cutting the supporting pieces from the head frame or the back frame, so that the replacing efficiency is greatly improved, and the production cost is reduced; and two fixed plates in the supporting piece are clamped on the upper side and the lower side of the head frame or the back frame, so that the welding surface is larger, and the connecting strength is higher.
