The ends of the two rotating screws 2110 that are close to each other respectively pass through the two gear boxes 2113 and the adjustment backrest 16 in turn and extend to the inside of the adjustment backrest 16. The left end of each rotating screw 2110 and the right end of each rotating screw 2110 are fixedly connected to a third bevel gear 2111, one of which The third bevel gear 2111 of the group is respectively meshed with the other group of second bevel gears 2109, wherein the third bevel gear 2111 and the other group of second bevel gears 2109 are respectively rotatably connected to the inside of the two gear boxes 2113, and the outer surface of each rotating screw 2110 is threadedly connected to a protective frame 2116, and the two protective frames 2116 are respectively slidably connected to the inside of the two positioning frames 2112, and the side surfaces of the two protective frames 2116 away from each other are respectively in contact with the side surfaces of the two gear boxes 2113 close to each other, and the front and back surfaces of each protective frame 2116 are fixedly connected to a limiting slider 2117, and the two groups of limiting sliders 2117 are respectively slidably connected to the inside of the two positioning frames 2112.By providing the protection blocking unit 21, the two limiting sliders 2117 can be brought close together when the adjustable backrest 16 pushes the pregnant woman to stand up, thereby conveniently blocking and protecting the pregnant woman on the adjustable backrest 16, thereby reducing the problem of the pregnant woman falling from the assisted obstetrics and gynecology nursing chair, thereby enabling the pregnant woman to be safely and stably helped to stand up from the obstetrics and gynecology nursing chair, and further enabling the pregnant woman to use the obstetrics and gynecology nursing chair safely and conveniently;

[0036] Both output ends of the dual-axis motor 2101 are fixedly connected to stabilizing bearings 2102. The outer ring of each stabilizing bearing 2102 is fixedly connected to the back of the seat frame 11. The stabilizing bearings 2102 can improve the rotational stability of the two output ends of the dual-axis motor 2101, thereby facilitating the adjustment of the backrest 16 and the angular stability of the seat frame 11.

[0037] The inner wall of each sliding cylinder 2114 is fixedly connected with a mounting bearing 2115, and the inner rings of the two mounting bearings 2115 are respectively fixedly connected to the outer surfaces of the two extension rods 2108. Since the extension rod 2108 rotates in the sliding cylinder 2114, the mounting bearings 2115 can improve the rotation stability of the extension rod 2108 in the sliding cylinder 2114, thereby improving the transmission stability of the structure.

[0038] The specific implementation of this embodiment is as follows: when a pregnant woman needs to use the obstetrics and gynecology nursing chair for obstetrics and gynecology nursing examination, the obstetrics and gynecology nursing chair is first placed on the horizontal ground by manual means, and the support structure composed of two sets of support legs 13 and the support chassis 14 can be used to stably support the obstetrics and gynecology nursing chair in the required position. Then, the dual-axis motor 2101 fixed on one side of the seat frame 11 is manually controlled, and the dual-axis motor 2101 can be used to provide dynamic driving force for the adjustment backrest 16 to rotate along the hinge axis of the seat frame 11, so that the angle of the adjustment backrest 16 hinged on one side of the seat frame 11 of the obstetrics and gynecology nursing chair can be easily adjusted until the adjustment backrest 16 can be set horizontally with the seat frame 11, so that it can be conveniently adjusted. The pregnant woman lies on the obstetrics and gynecology nursing chair, and can lean her head against the head support pillow 18 fixed by the mounting rod 17, so as to facilitate the obstetrics and gynecology nursing examination on the obstetrics and gynecology nursing chair. When the pregnant woman has finished the obstetrics and gynecology nursing examination, when she needs to get up, she can manually control the power supply of the dual-axis motor 2101, and use the dual-axis motor 2101 to drive the adjustment backrest 16 to rotate along the hinge axis of the seat frame 11, so that the adjustment backrest 16 can be rotated close to the seat frame 11 along the hinge axis, thereby making it convenient for the pregnant woman to get up from the obstetrics and gynecology nursing examination. At the same time, the power output by the dual-axis motor 2101 can be used to the two speed increasers 2103, and the speed increasing effect of the speed increaser 2103 can be used to make the two speed increasers 2103 rotate. The speed-increasing shaft 2104 rotates at a speed higher than the output speed of the dual-axis motor 2101, and the speed-increasing shaft 2104 drives the first bevel gear 2105 to rotate in the protective cover 2106. By providing a sliding groove 2107 outside the protective cover 2106 and arranging a slidable extension rod 2108 in it, the second bevel gear 2109 fixed at one end of the extension rod 2108 can be conveniently engaged with the first bevel gear 2105, so that the slidable second bevel gear 2109 can be conveniently rotated in the protective cover 2106. In addition, since the positioning frame 2112, the gear box 2113 and the sliding cylinder 2114 are fixed on both sides of the adjustment backrest 16, the extension rod 2108 can be rotated in the sliding cylinder 2114, and since the adjustment backrest 1 6 rotates along the seat frame 11, and can also make the sliding cylinder 2114 rotate along the outside of the protective cover 2106, so that the second bevel gear 2109 fixed on the outside of the extension rod 2108 can be conveniently engaged with the third bevel gear 2111 in the gear box 2113, and can conveniently drive the rotating screw 2110 to rotate in the gear box 2113 and the adjustment backrest 16. Since the thread groove is provided on the outside of the rotating screw 2110, it can be conveniently matched with the thread of the rotating screw 2110 through the protective block 2116. Since the protective block 2116 slides in the positioning frame 2112 and uses the limiting slider 2117 to slide in the positioning frame 2112, the stability of the two protective blocks 2116 sliding along the two rotating screws 2110 is improved.This makes it easy to move the two protective blocks 2116 closer together when adjusting the angle between the backrest 16 and the seat frame 11, thereby blocking and limiting the position of a pregnant woman lying on the backrest 16 on both sides. When helping a pregnant woman to stand up on the obstetrics and gynecology nursing chair, there is a risk of the pregnant woman falling due to the tilt of the backrest 16. The two protective blocks 2116 make it safer and more stable to help the pregnant woman to stand up on the backrest 16, thereby allowing the pregnant woman to use the obstetrics and gynecology nursing chair safely and conveniently.

[0039] Example 2: Please refer to Figure 1-Figure 7 The present invention provides a technical solution: a gynecological and obstetric nursing chair with an assisting function. The present invention makes corresponding improvements to the technical problems mentioned in the background technology.

Each positioning cylinder 2201 is connected to the mounting groove 2207. The inner bottom wall of each mounting groove 2207 is fixed. There are two limit blocks 2204 connected, and two sliding screws 2203 are respectively slidably connected to the inside of the two limit blocks 2204. The outer surface of each limit block 2204 is sleeved with a rotating block 2205. The bottom surface of each rotating block 2205 contacts the inner bottom wall of the mounting groove 2207. The upper surface of each rotating block 2205 is fixedly connected to a fourth bevel gear 2206. The bottom surfaces of the two fourth bevel gears 2206 contact the upper surfaces of the two limit blocks 2204 respectively. The two fourth bevel gears 2206 are respectively meshed with another set of third bevel gears 2111, and the two sliding screws 2203 are respectively threadedly connected to the inside of the two fourth bevel gears 2206. The inner wall of the mounting groove 2207 is movably hinged with a tilting push plate 2208, and the tilting push plate 2208 is slidably connected to the inside of the mounting groove 2207. The top of each sliding screw 2203 contacts the bottom surface of the tilting push plate 2208. By providing the pushing assist unit 22, the two sliding screws 2203 can be used to play the role of other transmission structures to facilitate pushing the tilting push plates 2208 hinged in the mounting groove 2207, so that the angle between the adjustment backrest 16 and the seat frame 11 of the obstetrics and gynecology nursing chair can be adjusted at the same time to drive the tilting push plates 2208 in the adjustment backrest 16 to generate auxiliary tilting thrust, which can more conveniently assist pregnant women to get up from the obstetrics and gynecology nursing chair, and further enable pregnant women to use the obstetrics and gynecology nursing chair conveniently;

[0042] Two stabilizing legs 2211 are fixedly connected to the bottom surface of the adjustable backrest 16. The bottom end of each stabilizing leg 2211 is movably hinged to a stabilizing base plate 2212. By fixing the two stabilizing legs 2211 to the bottom surface of the adjustable backrest 16 and the stabilizing base plate 2212 hinged thereto, an auxiliary support structure for the adjustable backrest 16 is formed, thereby providing auxiliary support for the adjustable backrest 16 when the adjustable backrest 16 is set horizontally.

The upper surface of each stabilizing ring 2202 is fixedly connected to the bottom surface of the adjustable backrest 16. The stabilizing ring 2202 is fixed to the connection between the positioning cylinder 2201 and the adjustable backrest 16, thereby enabling the positioning cylinder 2201 to be firmly fixed to the bottom surface of the adjustable backrest 16.

[0044] The upper surface of the tilting push plate 2208 is fixedly connected with a lumbar support cotton 2209, and the upper surface of the lumbar support cotton 2209 is fixedly connected with a wear-resistant silicone sleeve 2210. The lumbar support cotton 2209 is arranged on one side of the tilting push plate 2208, which can improve the comfort of the obstetrics and gynecology nursing chair, and the wear-resistant silicone sleeve 2210 is used to improve the wear resistance of the structure.

[0045] The specific implementation of this embodiment is as follows: while using two protective blocking frames 2116 to block and limit the two sides of the pregnant woman lying on the adjustable backrest 16, the two rotating rotating screws 2110 can be used to rotate the third bevel gear 2111, and since two positioning cylinders 2201 are fixed on the bottom surface of the adjustable backrest 16, the positioning cylinder 2201 can be connected with the mounting groove 2207 provided on the adjustable backrest 16, and a slidable sliding screw 2203 that limits rotation is provided in the positioning cylinder 2201, and a limiting block 2204 is fixed at the corresponding position of the positioning cylinder 2201, which can facilitate the rotation of the rotating block 2205 outside the limiting block 2204, and the rotating block 2205 cannot be moved along the limiting block 2204, and can only make the rotating block 2205 rotate, and since the fourth bevel gear 2206 fixed on the rotating block 2205 is threadedly connected with the sliding screw 2203, and can be used to rotate The third bevel gear 2111 fixed at one end of the screw 2110 is meshed with the fourth bevel gear 2206, which can facilitate the rotation of the rotating screw 2110 to drive the rotating block 2205 and the fourth bevel gear 2206 to rotate along the limit block 2204. Since the rotating fourth bevel gear 2206 is threadedly matched with the sliding screw 2203, the sliding screw 2203 can be easily moved along the positioning cylinder 2201 and the adjustment backrest 16. Since the inner wall of the mounting groove 2207 is movably hinged with a tilting push plate 2208, the two upwardly extending sliding screws 2203 can be used to push one side of the tilting push plate 2208 to enable the tilting push plate 2208 to rotate along the hinge axis, so as to help a pregnant woman lying on the lumbar support cotton 2209 and the wear-resistant silicone sleeve 2210 to get up, which can more conveniently assist the pregnant woman to get up from the obstetrics and gynecology nursing chair, and further enable the pregnant woman to use the obstetrics and gynecology nursing chair conveniently.

The present invention makes corresponding improvements to the technical problems mentioned in the background technology.

[0047] As a further limitation of the protective lifting aid mechanism 2 of the present invention, a tilt assist mechanism 3 is provided on the front of the push assist unit 22. The protective lifting aid mechanism 2 is used in conjunction with the tilt assist mechanism 3. The tilt assist mechanism 3 is used to assist in adjusting the backrest 16 for a pregnant woman lying on the backrest 16 to help her stand up.

[0048] The tilt assist mechanism 3 includes two lifting rods 302, the upper surface of each lifting rod 302 is fixedly connected to the bottom surface of the adjustable backrest 16, the upper surface of each lifting rod 302 is in contact with the bottom surface of the seat frame 11, the upper surface of each lifting rod 302 is fixedly connected to a lifting block 303, the inner wall of the seat frame 11 is movably hinged with a support plate 301, the support plate 301 is slidably connected to the inside of the seat frame 11, the upper surface of each lifting block 303 is in contact with the bottom surface of the support plate 301, and the bottom surface of the seat frame 11 is fixedly connected to two extension plates 304, the front surfaces of the two extension plates 304 are respectively fixedly connected to the outer surface of one group of support legs 13, and the two extension plates 304 are close to each other on one side. The surfaces are fixedly connected with a tilt auxiliary limit plate 305. By setting up a tilt auxiliary mechanism 3, the cooperation of the protective blocking unit 21 and the pushing assist unit 22 can be utilized, and the two limiting sliders 2117 can be utilized to block and protect the pregnant woman, and the angle between the adjustable seat frame 11 and the adjustable backrest 16 can be utilized. While the tilt pushing plate 2208 is used to push the pregnant woman to stand up, the lifting rod 302 and the lifting block 303 can be used to lift the support plate 301 hinged to the seat frame 11, so that the support plate 301 can be rotated along the hinge axis with the seat frame 11, and can assist the pregnant woman to stand up from the obstetrics and gynecology nursing chair, thereby further facilitating the use of the obstetrics and gynecology nursing chair by the pregnant woman.

[0049] The specific implementation of this embodiment is as follows: since the backrest 16 and the seat frame 11 are arranged horizontally, the lifting rod 302 fixed on the bottom surface of the backrest 16 can be extended to the bottom surface of the seat frame 11, and since the support plate 301 is movably hinged on the inner wall of the seat frame 11, the lifting block 303 fixed on the lifting rod 302 can be used to support the bottom surface of the support plate 301, so that the support plate 301 and the seat frame 11 can also be placed horizontally, thereby making it convenient for pregnant women to lie on the obstetrics and gynecology nursing chair, and when the angle of the backrest 16 and the seat frame 11 is adjusted and the two protective blocks 2116 are used to approach the pregnant woman. When blocking and protecting, and using the inclined push plate 2208 to assist the pregnant woman to stand up, the lifting rod 302 can carry the lifting block 303 to rotate along the hinge axis of the seat frame 11 and the adjustable backrest 16, which will make the lifting block 303 away from the support plate 301. The bottom of the support plate 301 has no support, which will also cause the support plate 301 to rotate along the hinge axis with the seat frame 11, so that the pregnant woman's hips and legs can be tilted downward until the bottom surface of the support plate 301 can contact the oblique side surfaces of the two inclined auxiliary limit plates 305, thereby making it more convenient for pregnant women to stand up from the obstetrics and gynecology nursing chair, and further making it easier for pregnant women to use the obstetrics and gynecology nursing chair.
