[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] Please see Figures 1-6 An adjustable obstetric delivery position support device includes a base 1, a fixed bracket 2 installed on the top of the base 1, an adjustable bracket 3 movably connected to the inner wall of the fixed bracket 2, a mattress 4 on the top of both the base 1 and the adjustable bracket 3, an outer shell 7 in the inner cavity of the adjustable bracket 3, a lifting block 10 in the inner cavity of the outer shell 7, an acrylic sliding sleeve 11 fixedly mounted on the outer edge of the lifting block 10, a connecting shaft 12 fixedly mounted on the bottom of the lifting block 10, rollers 13 installed at both ends of the connecting shaft 12, a long shaft 14 movably connected to the inner wall of the outer shell 7, snail blocks 15 installed at both ends of the long shaft 14, the snail blocks 15 contacting the rollers 13, an adjusting block 17 movably connected to the outer edge of the long shaft 14, a rotating handle 18 slidably connected to both the adjusting block 17 and the inner wall of the long shaft 14, and the adjusting block 17 slidably connected to the adjusting bracket 3. In the above structure, rotating the rotating handle 18 drives the adjusting block 17 and the long shaft 14 to rotate, thus allowing the snail block 15 to rotate. When the snail block 15 rotates, it can lift the roller 13, the connecting shaft 12, the lifting block 10, and the acrylic sliding sleeve 11 upwards, so that the top of the acrylic sliding sleeve 11 protrudes from the outer shell 7. The lifting block 10 and the acrylic sliding sleeve 11 are located at the waist of the person giving birth, thus supporting the waist of the person giving birth and improving the comfort of the person giving birth. When the snail block 15 rotates, it can drive the roller 13 to rotate. The rotation of the roller 13 on the snail block 15 can reduce the wear of the snail block 15 and improve the service life of the snail block 15.
[0017] In a preferred embodiment: the inner wall of the adjusting bracket 3 is provided with a sliding groove 5, and a sliding strip 6 is slidably connected to the inner wall of the sliding groove 5. The sliding strip 6 is fixedly assembled on the outer shell 7. In the above structure, the use of the sliding groove 5 and the sliding bar 6 together ensures that the outer shell 7 can only move horizontally, which improves the stability of the device. Since each childbirth patient has a different body shape, their waist position is also different. By moving the position of the outer shell 7, the device can be adapted to different body types of childbirth patients, thus improving the flexibility of the device.
[0018] In a preferred embodiment: the outer wall of the outer shell 7 is provided with a slide rail 8, and the inner wall of the slide rail 8 is slidably connected to a limiting post 9, which is fixedly assembled on the lifting block 10. In the above structure, the sliding rail 8 and the limiting post 9 work together to allow the lifting block 10 to move up and down in a directional manner in the outer shell 7. When the lifting block 10 moves up and down, it will drive the limiting post 9 to slide in the sliding rail 8, which improves the rationality of the device.
[0019] In a preferred embodiment: the snail block 15 is shaped similarly to a snail shell, and the outer wall of the snail block 15 is fixedly fitted with a piece 16; In the above structure, it can be observed from the shape of the snail's shell that the distance from the snail's outer contour line to the snail's midpoint gradually increases. Similarly, the distance from the outer contour line of the snail block 15 to the center point of the major axis 14 also gradually increases. Therefore, when the snail block 15 rotates, it can lift the roller 13, the connecting shaft 12, the lifting block 10, and the acrylic sliding sleeve 11, improving the rationality of the device. With the setting of the support plate 16, the support plate 16 can block the roller 13. When the major axis 14 cannot rotate, the lifting block 10 and the acrylic sliding sleeve 11 lift the mattress 4. At this time, the lifting block 10 and the acrylic sliding sleeve 11 are at their highest points.
[0020] In a preferred embodiment: the inner cavity of the adjusting block 17 is provided with a positioning groove 19, the inner cavity of the positioning groove 19 is slidably connected with a positioning strip 21, the positioning strip 21 is fixedly mounted on the rotating handle 18, and the outer edge of the positioning groove 19 is provided with a stop block 20, which is fixedly mounted on the inner wall of the adjusting block 17. In the above structure, through the cooperation of the positioning groove 19 and the positioning strip 21, when the positioning strip 21 is inserted into the positioning groove 19, the long shaft 14 cannot rotate. When the positioning strip 21 is not in the positioning groove 19, the long shaft 14 can be rotated by rotating the rotating handle 18. When it is necessary to fix the long shaft 14, the rotating handle 18 is pushed inward and rotated clockwise. When the positioning strip 21 contacts the stop block 20, the rotating handle 18 cannot rotate. At this time, the rotating handle 18 can be pushed inward again so that the positioning strip 21 on the rotating handle 18 is fully inserted into the positioning groove 19, so that the long shaft 14 can be fixed.
[0021] In a preferred embodiment: a lead screw 22 is fixedly mounted on the outer wall of the outer shell 7, a worm gear 23 is threadedly connected to the outer edge of the lead screw 22, the worm gear 23 is mounted on the adjusting bracket 3 through the mounting bracket 24, and a worm 25 is threadedly connected to the outer edge of the worm gear 23, and the worm 25 is movably connected to the adjusting bracket 3. In the above structure, the worm gear 25 is rotated to drive the worm wheel 23 to rotate, which in turn drives the lead screw 22 to move. When the lead screw 22 moves, it drives the outer shell 7, the lifting block 10, the acrylic sliding sleeve 11, the long shaft 14, the snail block 15, the adjusting block 17, and the rotating handle 18 to move, so that the position of the outer shell 7 can be adjusted.
[0022] Working principle: During use, when the mother's lower back needs support, the rotating handle 18 is pulled outwards to a fixed position. Rotating the rotating handle 18 causes the long shaft 14 to rotate within the adjusting block 17. At this time, the snail block 15 on the long shaft 14 gradually lifts the roller 13, connecting shaft 12, lifting block 10, and acrylic sliding sleeve 11, causing the lifting block 10 and acrylic sliding sleeve 11 to protrude from the outer shell 7. The lifting block 10 and acrylic sliding sleeve 11 then provide support for the mother's lower back. Once the lifting block 10 and acrylic sliding sleeve 11 are adjusted to the appropriate position, the rotating handle 18 is pulled outwards... While pushing inward, the rotation is clockwise. When the rotating handle 18 can no longer rotate, the positioning bar 21 contacts the stop block 20. By pushing the rotating handle 18 inward again, the positioning bar 21 is fully inserted into the positioning groove 19. At this time, the long shaft 14 cannot rotate. When it is necessary to adjust the position of the lifting block 10 and the acrylic sliding sleeve 11, the worm gear 25 is rotated to drive the worm wheel 23 to rotate. The worm wheel 23 drives the lead screw 22 to move. At this time, the outer shell 7 moves with the lead screw 22, gradually moving the position of the outer shell 7 upward, so that the lifting block 10 and the acrylic sliding sleeve 11 are located at the waist of the childbirther.
[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
