The third support bar 250 includes a fifth end 251 and a sixth end 252, the fifth end 251 being hinged to the third middle portion 244 of the second support bar 240, the sixth end 252 being pivotally connected to the seat frame 100, so that the front wheel 210 and the rear wheel 220 are relatively moved to raise or lower the height of the seat frame 100 when the angle between the third support bar 250 and the second support bar 240 is adjusted.
Further, as shown in fig. 4, the chair frame 100 may include a back cushion 110, a seat cushion 120, a first arm rest support 130, and a second arm rest support 140. The first arm rest support 130 is fixedly connected with the seat cushion 120, and the second arm rest support 140 is fixedly connected with the cushion 110. In connection with the connection of the chair frame 100 and the support assembly 200, the second end 232 is pivotally connected to the seventh end 141 of the first arm support 130 remote from the back pad 110, while the third end 241 is pivotally connected to the fourth intermediate portion of the first arm support 130, and the sixth end 252 is pivotally connected to the eighth end 142 of the first arm support 130 proximate to the back pad 110. The user places his hand on the first armrest support 130 when he desires his hand, and the second armrest support 140 is mainly used to be fixed with the support assembly 200.
Further, in the manner of pivotally connecting the third end portion 241 and the seventh end portion 141, the third end portion 241 may be provided with a first hook, the seventh end portion 141 is provided with a hook hole for passing through the first hook, and the first hook is hooked on the seventh end portion 141, so as to implement pivotally connecting the third end portion 241 and the seventh end portion 141. In addition, the second armrest support 140 includes a first armrest 145 and a second armrest 146 disposed in parallel, and fixed ends 147 disposed on the first armrest 145 and the second armrest 146, two ends of the first armrest 145 and the second armrest 146 are provided with protrusions 143, and two ends of the second armrest support 140 are provided with sliding grooves 144 engaged with the protrusions 143, so that the first armrest support 130 and the second armrest support 140 can move relatively in the sliding grooves 144, thereby adapting to different heights of the seat cushion 120. In this embodiment, the chute 144 is two opposite semicircular shapes.
Further, as shown in fig. 5 and 6, a certain angular limitation is required when the first support bar 230 or the second support bar 240 rotates, so as to avoid the situation that the front wheel 210 and the rear wheel 220 are closely attached, and the center of gravity of the chair frame 100 is unstable and collapses. Therefore, in the present embodiment, the first support rod 230 includes a first rod 234 and a second rod 235, the ninth end 236 of the first rod 234 is pivotally connected to the first armrest support 130, the tenth end 237 of the second rod 235 is fixedly connected to the first armrest support 130, and the eleventh end 248 of the second rod is fixedly connected to the seat cushion. When the first rod 234 rotates to a certain angle, the second rod 235 abuts against the first rod 234, and the angle of the first rod 234 is called the preset minimum angle. Since the first rod 234 is minimally rotated to this angle, the first and second support rods 230 and 240 do not come too tight to cause unstable center of gravity of the chair frame 100. In order to stabilize the contact between the first rod 234 and the second rod 235, a contact groove 239 for contacting the first rod 234 is provided between the second rod 235 and the seat cushion 120.
The rotation of the third support bar 250 can be realized by hand-operated adjustment, but in consideration of people with weak muscles, the third support bar 250 comprises a third bar body, and a rotating motor which is arranged at the third end portion 241 and pivoted with the second middle portion 243, and the nursing chair further comprises a control terminal, and the rotating clicking and control terminal is in communication connection. When the height adjustment command transmitted from the control terminal is detected, the rotation motor rotates around the second middle portion 243 to adjust the height of the seat cushion 120.
In addition, the rotary motor may include a central portion 254 and a rotary portion 253 pivotally connected to the central portion 254, the rotary portion 253 is fixedly connected to the third rod, and the central portion 254 is fixedly connected to the second intermediate portion 243. To protect the rotary motor, the third support bar 250 further includes a motor housing 256, and the motor housing 256 is disposed outside the rotary motor. For stable protection, as shown in fig. 7, in this embodiment, the motor housing 256 is U-shaped, two ends of the motor housing 256 are respectively engaged with the third end portion 241 and a middle area far away from the third end portion 241, and any one end is loosened, so that protection of the rotating motor can be also achieved.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present invention, and are not limiting; although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present invention.
