Therefore, we proposed a multifunctional maternity bed. Utility Model Content

[0005] This utility model proposes a multifunctional obstetric bed, which solves the problems in related technologies where the bed board length cannot be extended according to the patient's height and where the lighting cannot be disassembled and replaced in an emergency after it is damaged.

[0006] The technical solution of this utility model is as follows:

[0007] A multifunctional maternity bed includes a fixed bed board, a base plate, and an extension bed board. The base plate has symmetrically mounted casters at its bottom end and support rods symmetrically mounted at its top end. A mounting frame is mounted on the outer wall of each support rod, and an electric cylinder is mounted at the bottom end of each mounting frame. The output shaft of the electric cylinder passes through the outer wall of the mounting frame and connects to the extension bed board. A sliding rod is symmetrically mounted on the top end of each mounting frame, and the extension bed board is movably mounted on the outer wall of the sliding rod. First sliding blocks are symmetrically arranged on both sides of the extension bed board. A bed frame is connected to the end of each support rod and sliding rod furthest from the base plate. A fixed bed board is installed on the inner wall of the side. Slide grooves are symmetrically arranged on both sides of the bed frame. A baffle is movably installed on the bed frame through the slide grooves. A limit groove is provided on the inner wall of one side of the bed frame. The fixed bed board is movably installed on the inner wall of the bed frame through the limit groove. A threaded sleeve is provided on the outer wall of one side of the fixed bed board. A limit block is provided on the side of the fixed bed board away from the threaded sleeve. A servo motor is installed on the inner wall of the bed frame. The drive shaft of the servo motor is connected to a lead screw. The threaded sleeve is movably installed on the outer wall of the lead screw. A movable bed board is installed on the inner wall of the bed frame away from the fixed bed board.

[0008] Preferably, the outer wall of the lead screw is provided with an external thread, and the inner wall of the threaded sleeve is provided with an internal thread that matches the external thread.

[0009] Preferably, the outer wall of the first slider is provided with sliding holes, and the sliding holes are matched with the slider rod.

[0010] Preferably, the cross-section of the limiting block is trapezoidal, and the limiting block and the limiting groove fit together.

[0011] Preferably, a second slider is symmetrically arranged on both sides of the bottom end of the baffle, and the second slider fits into the groove.

[0012] Preferably, a mounting rod is installed at the top of the baffle, and a pull ring frame is installed at one end of the mounting rod.

[0013] Preferably, the bottom end of the mounting rod is symmetrically provided with movable grooves, and a telescopic rod is mounted on the mounting rod through the movable grooves. A spring is installed on the outer wall of the telescopic rod, a transmission block is provided at one end of the telescopic rod, and a positioning pin is provided on the side of the transmission block away from the telescopic rod. An LED lighting lamp is clamped and mounted on the mounting rod through the positioning pin.

[0014] Preferably, the LED lighting lamp has symmetrical fixing blocks on both sides, and each fixing block has a positioning hole on its outer wall, which matches the positioning pin.

[0015] The working principle and beneficial effects of this utility model are as follows:

[0016] In this invention, by using a baffle and a lead screw, if the mother is too tall, the sliding baffle moves her laterally along the slide groove to the inner wall of the bed frame via the second slider. The servo motor is then activated to drive the lead screw to rotate, which in turn drives the fixed bed board through the rotation of the lead screw and the threaded sleeve. Simultaneously, the limiting groove and the limiting effect on the fixed bed board cause it to move laterally along the slide groove on the inner wall of the bed frame, separating the fixed and movable bed boards. When the fixed and movable bed boards come into contact with the outer wall of the baffle, a gap appears between them. The electric cylinder is then activated, causing the extension bed board to move upwards. The limiting effect of the slide rod and the first slider ensures that the extension bed board precisely fills the gap between the fixed and movable bed boards, thus extending the bed board and maintaining a level overall bed, preventing unevenness from affecting use. This also ensures that the LED lighting and pull ring frame are always directly above the fixed bed board, preventing positional shifts caused by the movement of the fixed bed board and affecting usability.

[0017] In this invention, an LED light, a transmission block, and a telescopic rod are incorporated. When the LED light is damaged during production and needs to be disassembled, pressing the transmission block compresses the telescopic rod and spring. Simultaneously, the positioning pin at the front end of the transmission block moves out of the positioning hole, allowing the LED light to be pulled out from the bottom of the mounting rod. During installation, the transmission block is pressed horizontally to insert the top of the fixing block into the inner wall of the movable groove. Releasing the transmission block allows the spring deformation to cause the positioning pin to reset and engage in the positioning hole, thus fixing the LED light. This structure facilitates the disassembly and assembly of the LED light for emergency replacement and repair. Attached Figure Description

Detailed Implementation

[0026] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0027] Example 1: As Figures 1-6 As shown, this embodiment proposes a multifunctional obstetric bed, including a fixed bed board 2, a device base plate 10, and an extension bed board 14. Universal casters 11 are symmetrically mounted on the bottom end of the device base plate 10, and support rods 9 are symmetrically mounted on the top end of the device base plate 10. A mounting frame 8 is mounted on the outer wall of the support rods 9, and an electric cylinder 21 is mounted on the bottom end of the mounting frame 8. The output shaft of the electric cylinder 21 passes through the outer wall of the mounting frame 8 and connects to the extension bed board 14. Sliding rods 12 are symmetrically mounted on the top end of the mounting frame 8, and the extension bed board 14 is movably mounted on the outer wall of the sliding rods 12. First sliders 13 are symmetrically arranged on both sides of the extension bed board 14. The ends of the support rods 9 and sliding rods 12 away from the device base plate 10 are connected to the bed frame 1. A fixed bed board 2 is installed on the inner wall of one side of the bed frame 1. Slide grooves 22 are symmetrically arranged on both sides of the bed frame 1. A baffle 4 is movably installed on the bed frame 1 through the slide grooves 22. A limit groove 15 is provided on the inner wall of one side of the bed frame 1. The fixed bed board 2 is movably installed on the inner wall of the bed frame 1 through the limit groove 15. A threaded sleeve 16 is provided on the outer wall of one side of the fixed bed board 2. A limit block 20 is provided on the side of the fixed bed board 2 away from the threaded sleeve 16. A servo motor 17 is installed on the inner wall of the bed frame 1. The drive shaft of the servo motor 17 is connected to a lead screw 18. The threaded sleeve 16 is movably installed on the outer wall of the lead screw 18. A movable bed board 3 is installed on the inner wall of the bed frame 1 on the side away from the fixed bed board 2.

[0028] In this embodiment, the outer wall of the lead screw 18 is provided with an external thread, and the inner wall of the threaded sleeve 16 is provided with an internal thread that matches the external thread.

[0029] In this embodiment, the outer wall of the first slider 13 is provided with sliding holes, and the sliding holes are matched with the slider 12.

[0030] In this embodiment, the cross-section of the limiting block 20 is trapezoidal, and the limiting block 20 and the limiting groove 15 fit together.

[0031] Specific examples Figures 2-4 As shown, when using this structure, if the mother is too tall, the sliding baffle 4 moves laterally along the slide groove 22 via the second slider 19 to the inner wall of one side of the bed frame 1. The servo motor 17 is then activated to drive the lead screw 18 to rotate. The rotation of the lead screw 18 and the threaded sleeve 16 transmit power to the fixed bed board 2. At the same time, the limiting block 20 and the limiting groove 15 limit the fixed bed board 2, causing it to move laterally along the slide groove 22 on the inner wall of the bed frame 1, separating the fixed bed board 2 from the movable bed board 3. When it moves to contact the outer wall of the baffle 4, When a gap appears between the fixed bed board 2 and the movable bed board 3, the electric cylinder 21 is activated, causing the extension bed board 14 to move upward. At the same time, the sliding rod 12 and the first slider 13 limit the extension bed board 14, ensuring that the extension bed board 14 precisely fills the gap between the fixed bed board 2 and the movable bed board 3. This extends the bed board and keeps the entire bed level, preventing unevenness from affecting use. It also ensures that the LED lighting 6 and the pull ring frame 7 are always directly above the fixed bed board 2, preventing positional shifts caused by the movement of the fixed bed board 2 and affecting use.

[0032] Example 2: The bottom of the baffle 4 is symmetrically provided with second sliders 19 on both sides, and the second sliders 19 fit into the groove 22.

[0033] In this embodiment, a mounting rod 5 is installed at the top of the baffle 4, and a pull ring frame 7 is installed at one end of the mounting rod 5.

[0034] In this embodiment, the bottom end of the mounting rod 5 is symmetrically provided with movable grooves 24. The mounting rod 5 is equipped with a telescopic rod 26 through the movable grooves 24. A spring 27 is installed on the outer wall of the telescopic rod 26. A transmission block 25 is provided at one end of the telescopic rod 26. A positioning pin 28 is provided on the side of the transmission block 25 away from the telescopic rod 26. The mounting rod 5 is clamped and installed with an LED lighting lamp 6 through the positioning pin 28.

[0035] In this embodiment, fixing blocks 23 are symmetrically arranged on both sides of the LED lighting lamp 6. The outer wall of each fixing block 23 is provided with positioning holes 29, and the positioning holes 29 are matched with positioning pins 28.

[0036] Specific examples Figure 1 , Figure 5 and Figure 6As shown, when using this structure, if the LED lighting lamp 6 is damaged during production and needs to be disassembled, press the transmission block 25 to compress the telescopic rod 26 and the spring 27. At the same time, the positioning pin 28 at the front end of the transmission block 25 moves out of the positioning hole 29, and the entire LED lighting lamp 6 is pulled out from the bottom of the mounting rod 5. During installation, similarly, press the transmission block 25 horizontally to insert the top of the fixing block 23 into the inner wall of the movable groove 24, release the transmission block 25, and use the elastic force generated by the deformation of the spring 27 to make the positioning pin 28 reset and engage in the positioning hole 29 to fix the LED lighting lamp 6. This structure facilitates the disassembly and assembly of the LED lighting lamp 6 for emergency replacement and repair.

[0037] Working principle: During use, if the mother is too tall, the sliding baffle 4 moves laterally along the slide groove 22 via the second slider 19 to the inner wall of the bed frame 1. The servo motor 17 is activated, driving the lead screw 18 to rotate. The rotation of the lead screw 18 and the threaded sleeve 16 transmit power to the fixed bed board 2. Simultaneously, the limiting block 20 and limiting groove 15 limit the fixed bed board 2, causing it to move laterally along the slide groove 22 on the inner wall of the bed frame 1, separating the fixed bed board 2 from the movable bed board 3. When it contacts the outer wall of the baffle 4, a gap appears between the fixed bed board 2 and the movable bed board 3. The electric cylinder 21 is activated, moving the extension bed board 14 upwards. Simultaneously, the limiting effect of the slide rod 12 and the first slider 13 ensures that the extension bed board 14 precisely fills the gap between the fixed bed board 2 and the movable bed board 3, thus extending the bed board and maintaining the overall flatness of the bed, preventing unevenness from affecting use. This device ensures that the LED lighting lamp 6 and the pull ring frame 7 are always positioned directly above the fixed bed board 2, preventing positional shifts caused by movement of the fixed bed board 2 and affecting its use. Furthermore, if the LED lighting lamp 6 is damaged during production and needs to be disassembled, pressing the transmission block 25 compresses the telescopic rod 26 and spring 27. Simultaneously, the positioning pin 28 at the front end of the transmission block 25 moves horizontally out of the positioning hole 29, allowing the LED lighting lamp 6 to be pulled out from the bottom of the mounting rod 5. Similarly, during installation, pressing the transmission block 25 horizontally inserts the top of the fixing block 23 into the inner wall of the movable slot 24. Releasing the transmission block 25 allows the elastic force generated by the deformation of the spring 27 to reset the positioning pin 28, engaging it in the positioning hole 29 to fix the LED lighting lamp 6. This device allows for adjustment of the bed board length according to the patient's height and maintains the bed board's levelness, improving the user experience. It also facilitates the disassembly and assembly of the LED lighting lamp 6 for emergency replacement and repair.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
