Description
Technical Field
The invention relates to the technical field of massage chairs, in particular to a backrest structure which is attached to the back of a human body and can adjust the angle.
Background
Some seats are in the use, the back is at specific angle, when we held in the palm the waist, the headrest position adjustment is to comfortable angle, when personnel sat the back angle of regulation on the seat, discovery back waist held in the palm the position and can change along with the back angle and produce the displacement, lead to human lumbar vertebrae position and back waist to hold in the palm the position and take place the skew, the human body will make corresponding position adjustment, influence the user travelling comfort, therefore we have proposed a human back structure of back angle regulation of laminating and have been used for solving above-mentioned problem.
Disclosure of Invention
Based on the technical problems in the background art, the invention provides a backrest structure which is attached to the back of a human body to adjust the angle.
The invention provides a backrest structure for adjusting angles by fitting with the back of a human body, which comprises a backrest angle adjusting gear and a transmission rod positioned below the backrest angle adjusting gear, wherein the bottom of the backrest angle adjusting gear is connected with a transmission gear, the side surface of the transmission gear is connected with a height adjusting gear, the transmission gear and the height adjusting gear are integrated into a whole, the transmission gear and the height adjusting gear are fixedly sleeved on the transmission rod, one side of the backrest angle adjusting gear is provided with a bearing connecting seat, the bearing connecting seat is rotatably installed with the backrest angle adjusting gear and the transmission rod, the bearing connecting seat is connected with the backrest angle adjusting gear and the transmission rod to enable the backrest angle adjusting gear and the transmission rod to independently and freely run, the bottom of the height adjusting gear is connected with a track rack, and the track.
Preferably, a first circular hole is formed in one side of the transmission gear, and the inner side of the first circular hole is fixedly connected with the outer side of the transmission rod.
Preferably, a second circular hole is formed in one side of the height adjusting gear, and the inner side of the second circular hole is fixedly connected with the outer side of the transmission rod.
Compared with the prior art, the invention has the beneficial effects that:
through bearing connection seat, drive gear, track rack, height adjustment gear, back angle adjustment gear and the cooperation of transfer line, when the back will adjust the angle, back angle adjustment gear outwards overturns and drives height adjustment gear through drive gear and rotate, and height adjustment gear moves to cushion inside along track rack to draw close the back and reduce the laminating of height and back.
The chair back adjusting device is reasonable in design, solves the problem that the back curve and the chair curve can generate position deviation when the chair adjusts the angle of the backrest, does not need personnel to adjust the sitting posture, improves the comfort degree in the using process, meets the using requirement and is beneficial to use.
Drawings
FIG. 1 is a schematic structural view of a backrest structure for adjusting angles of a human back according to the present invention;
FIG. 2 is an enlarged schematic view of portion A of FIG. 1;
fig. 3 is a left side view of the structure of fig. 1.
In the figure: the device comprises a bearing connecting seat 1, a transmission gear 2, a track rack 3, a height adjusting gear 4, a backrest angle adjusting gear 5 and a transmission rod 6.
Detailed Description
The present invention will be further illustrated with reference to the following specific examples.
Examples
Referring to fig. 1-3, the embodiment provides a backrest structure for adjusting an angle by attaching to a human back, which includes a backrest angle adjusting gear 5 and a transmission rod 6 located below the backrest angle adjusting gear 5, wherein a transmission gear 2 is connected to the bottom of the backrest angle adjusting gear 5, a height adjusting gear 4 is connected to a side surface of the transmission gear 2, the transmission gear 2 and the height adjusting gear 4 are integrated, the transmission gear 2 and the height adjusting gear 4 are fixedly sleeved on the transmission rod 6, a bearing connecting seat 1 is disposed at one side of the backrest angle adjusting gear 5, the bearing connecting seat 1 is rotatably installed with the backrest angle adjusting gear 5 and the transmission rod 6, the bearing connecting seat 1 connects the backrest angle adjusting gear 5 and the transmission rod 6 to enable the backrest angle adjusting gear 5 and the transmission rod 6 to freely run independently, a track rack 3 is connected to the bottom of the height adjusting gear 4, the track rack 3 is engaged with, the chair back adjusting device is reasonable in design, solves the problem that the back curve and the chair curve can generate position deviation when the chair adjusts the angle of the backrest, does not need personnel to adjust the sitting posture, improves the comfort degree in the using process, meets the using requirement and is beneficial to use.
In the embodiment, one side of the transmission gear 2 is provided with the first circular hole, the inner side of the first circular hole is fixedly connected with the outer side of the transmission rod 6, one side of the height adjusting gear 4 is provided with the second circular hole, and the inner side of the second circular hole is fixedly connected with the outer side of the transmission rod 6.
In this embodiment, when the back will be adjusted, the back is kept away from the back, the rotation of back gear drives drive gear, drive gear drives the height gear, make it high gear move to track rack inside, when the back will adjust the angle, back angle adjustment gear 5 outwards overturns and drives drive gear 2 to rotate, because drive gear 2 and height adjustment gear 4 are as an organic whole, thereby drive height adjustment gear 4 and rotate, utilize drive gear 2 and height adjustment gear 4's transmission relation, make height adjustment gear 4 along track rack 3 to inside the cushion moving, thereby draw close the back and reduce the laminating of height and back, reach the purpose of concentric circles principle adjustment back.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
