Description

Technical Field

[0001] The invention relates to the technical field of medical auxiliary tools, and in particular to a labor-saving breastfeeding combined cushion. Background Art

[0002] In the process of infant growth, breastfeeding is the best way of feeding in the early stage of life and has irreplaceable importance. It not only provides safe and balanced nutrition for infants, but also gives them comprehensive immunity and other bioactive substances. Continuous breastfeeding can ensure that infants can obtain stable nutrition and immune protection, which is of great significance to promoting children's physical and mental health and early development. To achieve successful breastfeeding, correct breastfeeding posture and breast connection are crucial. In the correct posture, the mother and baby are in a comfortable position, the baby's body is close to the breastfeeder and the head and body are in a straight line, which helps the baby to suck the nipple effectively, stimulate the milk ejection reflex and prolactin secretion, and at the same time help the baby adapt to the mother's nipple, enhance the breastfeeder's confidence in breastfeeding, form a virtuous cycle of abundant milk, and avoid problems such as breast swelling and nipple cracking. When feeding, choose a comfortable posture. The breastfeeder should be completely relaxed, sitting or lying in a comfortable position, and can support herself with a pillow or quilt to avoid fatigue and muscle tension;

[0003] Some existing breastfeeding cushions are designed so that the angle cannot be easily adjusted and the user's waist is lacking in support, which may make it impossible to find the most comfortable breastfeeding posture when using them. This will cause the arm and back muscles to be tense for a long time during breastfeeding, causing soreness and fatigue. In addition, when breastfeeding, the user's body needs to bear the weight of the baby. If the waist is not properly supported, it will easily increase the burden on the spine and may even cause lumbar injury. If this continues for a long time, it may also cause chronic diseases such as lumbar muscle strain. Summary of the invention

[0023] To make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0024] As Figures 1-6 shown, a labor-saving breastfeeding combined cushion provided by the present invention includes two regulators 1. The regulator 1 further includes two bearing seats 2. One side of the two bearing seats 2 is fixedly connected with a connecting block 3. The top and bottom of the connecting block 3 are respectively fixedly installed with side blocks 4 and extend to the top and bottom of the two bearing seats 2 respectively. A guide groove 5 is opened in the lower side block 4, and a guide shaft 6 is fixedly installed in the guide groove 5. A ratchet 7 is also rotatably connected between the two bearing seats 2. An operating shaft 8 is also movably installed between the two bearing seats 2 near the ratchet 7. A pawl 9 is movably installed on the operating shaft 8. A backrest support rod 10 is movably connected between the two pawls 9, and lumbar support rods 12 are fixedly connected to both ends of the backrest support rod 10. A seat cushion rod 11 is fixedly connected between the two connecting blocks 3. A seat cushion wrapping layer 13 is sleeved between the two regulators 1 and the seat cushion rod 11. A backrest wrapping layer 14 is sleeved between the backrest support rod 10 and the seat cushion wrapping layer 13. A lumbar wrapping layer 15 is sleeved between the lumbar support rods 12 and the seat cushion wrapping layer 13. Protective covers 28 are fixedly installed on the outer sides of the two bearing seats 2.

[0025] A first compression spring 16 is sleeved outside the guide shaft 6. A guide groove 5 is provided in one of the side blocks 4, and the first compression spring 16 is arranged outside the guide shaft 6 in the guide groove 5, which can provide conditions for the meshing connection between the pawl 9 and the ratchet wheel 7. A spline hole 17 is provided in the middle of the ratchet wheel 7. Both ends of the backrest support rod 10 pass through the through holes in the corresponding bearing seats 2 and are inserted and installed in the corresponding spline holes 17. A spline is fixedly installed on the outside of the backrest support rod 10 located in the spline hole 17. The lumbar support rod 12 is placed between two of the bearing seats 2. Inserting both ends of the backrest support rod 10 into the spline holes 17 of the corresponding ratchet wheels 7 respectively can enable the backrest support rod 10 to adjust and limit the angle of the backrest support rod 10 by means of the one-way limit of the ratchet wheel 7 and the pawl 9. At the same time, the backrest support rod 10 drives the lumbar support rod 12 to rotate synchronously, and the waist of the user can be supported by means of the angle difference between the backrest support rod 10 and the lumbar support rod 12. A first shaft hole 18 is provided in one of the bearing seats 2, and a polygonal hole 19 is provided in the other bearing seat 2. A spiral guide block 22 is fixedly installed on the outside of the operating shaft 8. A fixing ring 23 is fixedly installed on the outside of the operating shaft 8 near the spiral guide block 22. A limiting shaft 20 is fixedly installed on one side of the operating shaft 8. The longitudinal section of the limiting shaft 20 is a regular hexagon. A fixing stud 21 is fixedly installed on the side of the limiting shaft 20 facing away from the operating shaft 8. The operating shaft 8 located between the fixing ring 23 and the spiral guide block 22 is inserted and installed in the first shaft hole 18, and the limiting shaft 20 is inserted and installed in the polygonal hole 19. One fixing stud 21 is fixedly connected to the other operating shaft 8 through a connecting rod 30. A nut is threadedly connected to the outside of the other fixing stud 21. A second compression spring 24 is sleeved on the outside of the operating shaft 8. One side of the second compression spring 24 abuts against one side of one of the bearing seats 2, and the other side of the second compression spring 24 abuts against one side of the fixing ring 23. Inserting the operating shaft 8 between the two bearing seats 2 through the limiting shaft 20 can realize the radial movement of the operating shaft 8 between the two bearing seats 2, thereby providing conditions for manually adjusting the pawl 9. A second shaft hole 25 is provided in the operating shaft 8. A spiral guide groove 26 is provided on the inner side of the second shaft hole 25. A guide rod 27 is fixedly installed on the outside of the pawl 9. A slot 28 is provided in the guide rod 27. One end of the pawl 9 is inserted and installed on the operating shaft 8 through the second shaft hole 25, and the spiral guide groove 26 is slidably connected to the spiral guide block 22. The end of the guide rod 27 away from the pawl 9 extends into the guide groove 5, and the slot 28 is inserted and installed on the guide shaft 6. One end of the first compression spring 16 abuts against the outside of the guide rod 27. The end of the pawl 9 away from the second shaft hole 25 is meshed with the ratchet wheel 7. Rotating one end of the pawl 9 on the operating shaft 8 through the second shaft hole 25 and the spiral guide groove 26 can cooperate with the acting force of the first compression spring 16 on the guide rod 27 to make the other end of the pawl 9 always meshed with the ratchet wheel 7, thereby realizing the one-way rotation of the ratchet wheel 7, that is, cooperating with the ratchet wheel 7 to provide the limiting and supporting ability for the backrest support rod 10.

[0026] It should be noted that the present invention is a labor-saving breastfeeding combination cushion. When increasing the angle between the backrest support rod 10 and the seat cushion rod 11, one hand can hold the lumbar cushion wrapping layer 15 outside the backrest support rod 10, and push the backrest support rod 10 through the lumbar cushion wrapping layer 15, so that both ends of the backrest support rod 10 drive the two ratchets 7 to rotate synchronously through the splines on the outside. Then, when the two ratchets 7 rotate between the corresponding two bearing seats 2, one end of the corresponding pawl 9 is squeezed and displaced, so that the pawl 9 rotates around the second shaft hole 25 inside. At the same time, the spiral guide groove 26 inside the second shaft hole 25 slides on the spiral guide block 22 outside the operating shaft 8, so that the pawl 9 pushes the operating shaft 8 to move to one side. Synchronously, the guide rod 27 outside the pawl 9 penetrates and moves on the corresponding guide shaft 6 through the slot 28 and compresses the first compression spring 16, so that when the toothed groove part outside the ratchet 7 rotates to the position of the pawl 9, the pawl 9 can be pushed by the acting force of the first compression spring 16 stretching and rebounding, and one end of the pawl 9 is clamped into the toothed groove outside the ratchet 7, thus realizing the one-way limit of the ratchet 7. When the backrest support rod 10 rotates to adjust the angle, both ends of the backrest support rod 10 also drive the lumbar support rod 12 to rotate synchronously, so that the lumbar cushion wrapping layer 15 outside the lumbar support rod 12 rotates synchronously with the backrest wrapping layer 14 and one side of the lumbar cushion wrapping layer 15 protrudes from one side of the backrest wrapping layer 14, thus providing support for the user's waist;

[0027] When it is necessary to reversely adjust the angle of the backrest support rod 10, that is, to increase the angle between the backrest support rod 10 and the seat cushion rod 11, one hand can hold the backrest wrapping layer 14 outside the backrest support rod 10, and press the seat cushion wrapping layer 13 on one side of one of the bearing seats 2, so that the operating shaft 8 moves to one side in the first shaft hole 18, and the operating shaft 8 drives the limit shaft 20 to move to one side in the polygonal hole 19 synchronously. And the fixing ring 23 outside the operating shaft 8 compresses the second compression spring 24 to one side of one of the bearing seats 2. Furthermore, the operating shaft 8 also moves radially in the second shaft hole 25, and the spiral guide block 22 outside the operating shaft 8 is slidably connected with the spiral guide groove 26 to promote one end of the pawl 9 to rotate, so that the other end of the pawl 9 is disengaged from the ratchet 7. Synchronously, one of the fixing studs pushes the other operating shaft 8 to move in the same direction through the connecting rod 30. At this time, the backrest support rod 10 can be manually pushed, so that both ends of the backrest support rod 10 drive the corresponding ratchets 7 to rotate reversely and drive the lumbar support rod 12 to rotate synchronously, thus reversely adjusting the angles of the backrest support rod 10 and the lumbar support rod 12. After the adjustment is completed, the operating shaft 8 can be released, and then the fixing ring 23 is pushed back by the acting force of the second compression spring 24 stretching and rebounding. Synchronously, the first compression spring 16 pushes the pawl 9 upward, so that one end of the pawl 9 is re-engaged with the ratchet 7, thus limiting the ratchet 7 and realizing the angular limit of the pawl 9.
