Description

Technical Field

[0001] This invention relates to the field of medical bed application technology, and in particular to an adjustable bed frame suitable for dental consultations and its usage method. Background Technology

[0002] In healthcare settings, hospital beds serve as core equipment for patient treatment, rehabilitation, and rest. Their functionality and safety directly impact the patient's treatment experience and the efficiency of nursing care. With advancements in medical technology and the diversification of nursing needs, healthcare professionals and patients have placed higher demands on the adjustability of hospital beds. These beds not only require flexible overall height adjustment to accommodate the operational needs of healthcare workers of varying heights or facilitate patient entry and exit, but also need multi-angle bending capabilities to allow patients to change positions such as turning over, sitting up, and semi-reclining, thus assisting in rehabilitation activities or enhancing rest comfort. Furthermore, to prevent patients from rolling off the bed due to turning over, moving, or loss of consciousness, protective structures are typically installed on both sides of the bed to ensure patient safety.

[0003] In hospital ICUs, geriatric wards, or rehabilitation centers, many long-term bedridden and immobile patients often suffer from serious oral health problems (such as periodontitis, residual roots and crowns, oral ulcers, etc.), requiring consultation and bedside treatment by dentists. However, traditional medical bed designs primarily focus on patient rest and basic daily care, exhibiting significant shortcomings when applied to specialized dental treatment:

[0004] Height and position limitations: Traditional hospital beds are low in height and have limited adjustment range. When performing delicate procedures such as tooth extraction, filling, or cleaning, dentists often need to bend over for a long time or adopt extremely uncomfortable postures, making it difficult to obtain a clear view of the surgical area and easily leading to occupational musculoskeletal injuries.

[0005] Lack of professional positioning support: Dental treatment usually requires patients to be in a specific head-up, feet-down or semi-reclining position (similar to the dental chair position) to prevent swallowing or aspiration of rinsing water. Ordinary hospital beds often have a single angle for backrest adjustment and lack a leg-linked anti-slip design, making it difficult to maintain a stable treatment position.

[0006] Side operation is obstructed: Even when the side rails of the hospital bed are lowered, there are often protruding folding mechanisms or connecting rods, which makes it impossible for doctors to get close to the patient's head to operate. It also hinders the approach of portable dental treatment machines (trolleys), which seriously affects the transfer of instruments and the flexibility of operation.

[0007] Therefore, there is an urgent need for an adjustable hospital bed frame that can accommodate dentists carrying portable equipment for bedside consultations, has adjustment functions similar to a dental chair, and is unobstructed from the sides. Summary of the Invention

[0008] The technical problem to be solved by the present invention is to provide an adjustable bed frame suitable for oral consultation and its usage method. By realizing a wide range of bed lifting and lowering, multi-angle simulation of body position and complete concealment of guardrails, it meets the special needs of bedside oral diagnosis and treatment for field of vision, operating space and body position.

[0009] To solve the above-mentioned technical problems, the present invention provides an adjustable bed frame suitable for dental consultations, including an adjustable base to adjust the height of the entire bed, meeting the operational height requirements of dentists carrying portable equipment for bedside treatment; two connecting side plates are fixed to the top of the adjustable base by bolted connecting blocks, allowing the bed to be adjusted via the connecting side plates; the adjustable bracket is located between the two connecting side plates and is bolted to the top of the adjustable base by a connecting block rotatably connected by a pin, allowing for multi-angle bending adjustment of the bed frame; the bed frame is bolted to the top of the two connecting side plates to support the entire bed for the patient; two protective side frames are slidably connected to both sides of the bed frame and connected to the ends of the two side plates, allowing for different height adjustments on both sides of the bed frame to prevent the patient from rolling out of the bed; the bed frame has a two-section structure and is rotatably connected inside the bed frame, allowing the patient to change positions.

[0010] The invention is further configured such that: the adjusting base includes a movable seat with rollers; a first cylinder is rotatably connected to the bottom of the movable seat near one end center; a crossbar is rotatably connected to the end face of the drive rod of the first cylinder; side rods are symmetrically fixedly connected to both ends of the crossbar; connecting pipes are fixedly connected to the end faces of both side rods; C-shaped rods are rotatably connected to the end faces of both connecting pipes; reinforcing shafts are fixedly connected to the end faces of both sets of C-shaped rods; connecting frames are rotatably connected to the end faces of both reinforcing shafts; and the two connecting frames are respectively connected to the connecting side plates at both ends by connecting block bolts; and reinforcing components are symmetrically rotatably connected to the two reinforcing shafts near the middle.

[0011] With the above technical solution, when it is necessary to adjust the overall height of the hospital bed, the drive rod of the first cylinder extends and retracts, driving the crossbar and the side rods on both sides to move. The side rods pull the C-shaped rod to rotate around the side wall of the moving seat through the connecting pipe fittings. The C-shaped rod drives the connecting side plate and the bed frame to rise and fall through the reinforcing shaft and the connecting frame, thereby realizing the adjustment of the hospital bed height. At the same time, the reinforcing shaft drives the reinforcing components to move synchronously, ensuring the structural stability of the adjustment base during the lifting process and preventing the hospital bed from shaking.

[0012] The present invention is further configured such that the two sets of C-shaped rods are rotatably connected to the two side walls of the movable seat.

[0013] Through the above technical solution, two sets of C-shaped rods are rotatably connected to the two side walls of the movable seat, so that the C-shaped rods can rotate stably around the fixed fulcrum under the drive of the first cylinder, forming a symmetrical support structure. This ensures that the force on both sides is balanced when the bed is raised or lowered, avoids the bed tilting due to force on one side, and improves the stability and safety of the height adjustment process.

[0014] The present invention is further configured such that: the reinforcing component includes a positioning shaft, a mounting block is sleeved at the middle position of the positioning shaft, and the mounting block is bolted to the top of the movable seat; sleeves are symmetrically rotatably connected to both ends of the positioning shaft; a pull rod is provided through the end face of each of the two sleeves; a limit plate is provided at one end of the pull rod located inside the sleeve; the other end of the pull rod is rotatably connected to the reinforcing shaft; and a damping spring is provided inside the sleeve.

[0015] Through the above technical solution, the reinforcement component is fixed to the moving seat by the mounting block to form a stable support base. When the reinforcement shaft moves with the C-shaped rod, the pull rod slides in the sleeve. The pull rod drives the limit plate to squeeze or stretch the damping spring. The reaction force generated by the damping spring can buffer the impact force during the lifting process. At the same time, the sleeve rotates around the positioning shaft to adapt to the movement trajectory of the reinforcement shaft, further enhancing the anti-shaking ability of the adjustment base and ensuring the structural stability of the bed during lifting.

[0016] The invention is further configured such that: the outer wall of the limiting plate is smoothly attached to the inner wall of the sleeve, and the inner bottom of the sleeve is respectively pressed against the two ends of the damping spring.

[0017] Through the above technical solution, the outer wall of the limiting plate and the inner wall of the sleeve are smoothly fitted, which can avoid jamming when the pull rod slides and ensure that the damping spring can extend and retract smoothly. At the same time, the limiting plate and the bottom of the sleeve respectively press against the two ends of the damping spring, so that the damping spring is always in a pre-compressed state, which can timely buffer the movement of the pull rod, effectively absorb the vibration during the lifting process, and improve the stability and comfort of the use of the hospital bed.

[0018] The present invention is further configured such that: the adjusting bracket includes two S-shaped rods and a rotating tube respectively rotatably connected to the bottom of the two reclining frames; a first reinforcing rod is fixedly connected to the opposite surfaces of the two S-shaped rods; the two S-shaped rods are respectively rotatably connected to a connecting block installed on a connecting frame near the bottom; and a second cylinder is rotatably connected to the bottom end face of one of the S-shaped rods.

[0019] A fixing component is welded to the bottom of the rotating tube near its end face, and the fixing component is rotatably connected to a third cylinder. Support rods are symmetrically welded to the rotating tube near its end face, and the support rods are rotatably connected to the reclining frame. Support rods are symmetrically rotatably connected to the rotating tube near its middle position. Telescopic components are inserted and slidably connected to the end faces of the two support rods, and are rotatably connected to the bend at one end of the reclining frame through the telescopic components. A second reinforcing rod is fixedly connected to the opposite faces of the two support rods.

[0020] Through the above technical solution, the adjusting bracket is connected to the reclining frame via S-shaped rods and rotating tubes, enabling independent adjustment of the two-section reclining frame. When the angle of the upper half of the reclining frame needs to be adjusted, the second cylinder drives the S-shaped rod to rotate around the connecting block, and the S-shaped rod pushes the upper half of the reclining frame to flip. The first reinforcing rod enhances the structural strength of the two S-shaped rods to prevent deformation. When the angle of the lower half of the reclining frame or the bend needs to be adjusted, the third cylinder drives the rotating tube to rotate via a fixing component. The rotating tube supports the lower half of the reclining frame via a support rod, and at the same time, it pushes the bend of the reclining frame to move via a support rod and a telescopic component. The telescopic component can adaptively slide with changes in the bending angle of the reclining frame. The second reinforcing rod enhances the stability of the support rod, enabling precise bending of the reclining frame at multiple angles.

[0021] The present invention is further configured such that: the second cylinder and the third cylinder are respectively located at two corresponding connecting side plates, and are respectively rotatably connected to the connecting blocks on the two connecting side plates.

[0022] Through the above technical solution, the second and third cylinders are rotatably connected to the connecting blocks of the corresponding connecting side plates, so that when the cylinder drives the adjustment bracket to move, it can rotate around the connecting block to adapt to the rotation trajectory of the S-shaped rod and the rotating tube, avoiding damage to the cylinder due to forced force, and ensuring that the cylinder driving force can be stably transmitted to the adjustment bracket, thereby improving the reliability of the bending adjustment of the reclining frame.

[0023] The invention is further configured such that: the protective side frame includes two sets of U-shaped tubes that slide through both sides of the frame, and the top of each set of U-shaped tubes is bolted with a cap. The U-shaped tubes can be hidden in the protective groove opened at the U-shaped tubes in the frame at the lowest point through the caps. Each set of U-shaped tubes consists of three tubes, and multiple protective tubes are welded equidistantly inside. A drive mechanism is engaged with the U-shaped tube located in the middle of each set through a conical tooth block opened on its outer wall. A stabilizing frame is sleeved and slidably attached to the outer wall of each U-shaped tube located away from the middle of each set, and the stabilizing frame is bolted to the connecting side plate.

[0024] Through the above technical solution, the protective side frame is slidably connected to the bed frame via a U-shaped tube, enabling height adjustment. When protection is needed, the drive mechanism drives the middle U-shaped tube to rise via a bevel gear block. The middle U-shaped tube, through the protective fitting, drives the two U-shaped tubes to rise synchronously, forming a protective barrier to prevent the patient from rolling off. When protection is not needed, the drive mechanism drives the U-shaped tube to descend until the cap is flush with the bed frame surface, and the U-shaped tube is hidden in the protective groove, eliminating the protruding structure. The stabilizing frame guides and stabilizes the two U-shaped tubes, ensuring that the U-shaped tubes do not deviate during lifting and lowering, thus improving the reliability of the protective side frame.

[0025] The present invention is further configured such that: the driving mechanism includes a mounting plate installed on the end face of the connecting side plate, a motor is bolted to the top of the mounting plate near one end, a drive wheel is fixedly connected to the end face of the output shaft of the motor, the drive wheel is connected to the driven wheel via a transmission belt sleeved on its outer wall, a transmission shaft is interference-fitted to the inner wall of the driven wheel, a bevel gear is fixedly connected to the end face of the transmission shaft, and the bevel gear is meshed with a U-shaped tube through bevel gear blocks.

[0026] Through the above technical solution, the drive mechanism is fixed to the connecting side plate by the mounting plate. After the motor starts, the output shaft drives the drive wheel to rotate. The drive wheel drives the driven wheel and the drive shaft to rotate through the transmission belt. The drive shaft drives the bevel gear to rotate. The bevel gear, through meshing with the bevel gear block, converts the rotational motion into the linear lifting motion of the U-shaped tube, realizing the height adjustment of the protective side frame. Through the cooperation of gear transmission and belt transmission, the driving force is ensured to be transmitted smoothly and accurately. The lifting height of the U-shaped tube can be controlled according to the needs to meet the requirements of different protection scenarios.

[0027] On the other hand, a method for using an adjustable hospital bed frame suitable for dental consultations is provided, including the following steps:

[0028] S1. Bed movement and initial positioning: Push the bed frame 4 and move the bed to the target position by adjusting the rollers of the bottom moving seat 11 of the base 1. Move the bed to a position that is convenient for the dentist to operate and for the portable diagnostic and treatment equipment to be placed. After the movement is completed, lock the rollers to ensure that the bed position is fixed and to prevent displacement during use.

[0029] S2. Treatment height matching adjustment: Based on the dentist's height and operating habits (standing or sitting posture), the first cylinder 12 is activated to drive the adjustment base 1 to rise and fall until the bed frame 4 reaches the optimal treatment height, avoiding excessive bending of the doctor. The first cylinder 12 drives the rod to extend and retract, causing the crossbar 13 and side rod 14 to move. The side rod 14 pulls the C-shaped rod 16 to rotate around the side wall of the moving seat 11 through the connecting pipe 15. The C-shaped rod 16 drives the connecting side plate 2 and bed frame 4 to rise and fall through the reinforcing shaft 17 and connecting frame 18. At the same time, the reinforcing shaft 17 pulls the pull rod 194 of the reinforcing component 19, causing the limiting plate 195 to squeeze the damping spring 196, buffering the impact of the rise and fall, until the bed frame 4 reaches the target height, and the first cylinder 12 is closed.

[0030] S3. Oral Treatment Position Adjustment: Adjust the angle of the recumbent frame 6 according to the oral treatment field of vision requirements: If the angle of the upper half of the recumbent frame needs to be adjusted, activate the second cylinder 31. The second cylinder 31 drives the S-shaped rod 311 to rotate around the connecting block 21. The S-shaped rod 311 pushes the upper half of the recumbent frame 6 to rotate to the target angle. Close the second cylinder 31 and raise the patient's head to a semi-recumbent or sitting position to prevent aspiration of treatment water and exposure of the deep oral field of vision. If the angle of the lower half of the recumbent frame or the bend needs to be adjusted, activate the third cylinder 32 to adjust the leg support to prevent the patient from sliding down. The third cylinder 32 drives the rotating tube 322 to rotate through the fixing part 321. The rotating tube 322 supports the lower half of the recumbent frame 6 through the support rod 323. At the same time, the support rod 324 drives the telescopic part 325 to push the bend of the recumbent frame 6 to move until a comfortable oral treatment position is achieved. Close the third cylinder 32.

[0031] S4. Treatment Space Expansion and Protection: Control the lifting and lowering of the protective side frame 5 according to treatment needs: If oral treatment is required, start the motor 552 in reverse before treatment begins to drive the U-shaped tube 51 to descend until the cap 52 is flush with the surface of the bed frame 4, and the U-shaped tube 51 is hidden in the protective groove 41. Then, turn off the motor 552 to eliminate lateral obstruction and allow the doctor's body and portable treatment device to perform fine operations close to the bedside. If patient protection is required, start the motor 552 of the drive mechanism 55. The motor 552 drives the driven wheel 555 and the drive shaft 556 to rotate through the drive wheel 553 and the transmission belt 554. The drive shaft 556 drives the bevel gear 557 to mesh with the bevel gear block 511 of the U-shaped tube 51, driving the U-shaped tube 51 to rise along the stabilizer 54 to form a protective barrier. Then, turn off the motor 552.

[0032] S5. Reset after use: After the patient leaves or after the nursing care is completed, start the third cylinder 32 and the second cylinder 31 in reverse order to restore the bed frame 6 to a horizontal state; start the first cylinder 12 in reverse order to lower the bed frame 4 to the lowest height; start the motor 552 in reverse order to completely hide the protective side frame 5 in the protective groove 41; finally, unlock the rollers, move the bed to the storage position and lock the rollers to restore it to the daily care or storage state.

[0033] The beneficial effects of this invention are as follows:

[0034] 1. Optimized Ergonomics for Diagnosis and Treatment: By adjusting the base (first cylinder and C-shaped rod structure), the overall height of the bed can be flexibly raised and lowered, which can raise the patient's oral cavity position to a comfortable operating plane for the doctor. In conjunction with the use of portable treatment devices, it can effectively reduce the burden on the doctor's back during bedside consultations.

[0035] 2. Eliminating operational obstacles and facilitating portable equipment: By optimizing the design of the protective side frame structure, a drive mechanism allows the U-shaped tube to be completely concealed within the protective groove when lowered to its lowest point, making the side of the bed flush with the mattress surface. This design eliminates the protrusions of traditional guardrails, allowing dentists to perform precise operations at close range to the patient's head. It also facilitates the extension of tubing and trays of portable dental carts to the optimal position, improving treatment efficiency.

[0036] 3. Simulated dental chair positioning to ensure medical safety: The two-section reclining frame can be independently and precisely adjusted via adjustable supports (S-shaped rods, rotating tubes, and telescopic components), allowing patients to achieve a "semi-recumbent" or "Fowler position" similar to a professional dental chair while on a regular hospital bed. This position not only facilitates exposure of the deep surgical area of ​​the oral cavity but also effectively utilizes gravity to prevent irrigation fluid or foreign objects from entering the airway during treatment, thus improving the safety of bedside dental treatment.

[0055] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby providing a clearer and more explicit definition of the scope of protection of the present invention.

[0056] like Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, an adjustable bed frame suitable for dental consultations includes an adjustable base 1 for adjusting the height of the entire bed. The adjustable base 1 includes a movable seat 11 with rollers. A first cylinder 12 is rotatably connected to the bottom of the movable seat 11 near the center of one end. A crossbar 13 is rotatably connected to the end face of the drive rod of the first cylinder 12. Side rods 14 are symmetrically fixed to both ends of the crossbar 13. Connecting pipes 15 are fixedly connected to the end faces of both side rods 14. C-shaped rods 16 are rotatably connected to the end faces of both connecting pipes 15. The two sets of C-shaped rods 16 are rotatably connected to the two side walls of the movable seat 11, respectively. By rotatably connecting the two sets of C-shaped rods 16 to the two side walls of the movable seat 11, the C-shaped rods 16 can rotate stably around a fixed fulcrum under the drive of the first cylinder 12, forming a symmetrical support structure to ensure that the force is distributed on both sides when the bed is raised or lowered. To ensure balance and prevent bed tilting due to unilateral force, thus improving the stability and safety of height adjustment, two sets of C-shaped rods 16 are fixedly connected to their end faces with reinforcing shafts 17. Each reinforcing shaft 17 is rotatably connected to a connecting frame 18 near its end face. The two connecting frames 18 are bolted to the connecting side plates 2 at both ends via connecting blocks 21. When the overall height of the bed needs to be adjusted, the drive rod of the first cylinder 12 extends and retracts, moving the crossbar 13 and the side rods 14 on both sides. The side rods 14 pull the C-shaped rods 16 around the side wall of the moving seat 11 via connecting pipes 15. The C-shaped rods 16, through the reinforcing shafts 17 and connecting frames 18, drive the connecting side plates 2 and the bed frame 4 to rise and fall, thus adjusting the bed height. Simultaneously, the reinforcing shafts 17 drive the reinforcing components 19 to move synchronously, ensuring the structural stability of the adjusting base 1 during the lifting process and preventing bed swaying.

[0057] like Figure 5 and Figure 7 As shown, two reinforcing shafts 17 are symmetrically rotatably connected to reinforcing components 19 near their center positions. Each reinforcing component 19 includes a positioning shaft 191. A mounting block 192 is sleeved at the center of the positioning shaft 191 and bolted to the top of the movable seat 11. Sleeves 193 are symmetrically rotatably connected to both ends of the positioning shaft 191. A pull rod 194 is provided through the end face of each sleeve 193. A limit plate 195 is provided at one end of the pull rod 194 inside the sleeve 193, and the other end of the pull rod 194 is rotatably connected to the reinforcing shaft 17. The inside of the sleeve 193 is provided with… A damping spring 196 is provided, and the reinforcing component 19 is fixed to the movable seat 11 by the mounting block 192 to form a stable support base. When the reinforcing shaft 17 moves with the C-shaped rod 16, it pulls the pull rod 194 to slide in the sleeve 193. The pull rod 194 drives the limiting plate 195 to squeeze or stretch the damping spring 196. The reaction force generated by the damping spring 196 can buffer the impact force during the lifting process. At the same time, the sleeve 193 rotates around the positioning shaft 191 to adapt to the movement trajectory of the reinforcing shaft 17, further enhancing the anti-shaking ability of the adjusting base 1 and ensuring the structural stability of the bed during lifting.

[0058] The outer wall of the limiting plate 195 is smoothly fitted to the inner wall of the sleeve 193, and the inner bottom of the sleeve 193 is respectively pressed against the two ends of the damping spring 196. The smooth fit between the outer wall of the limiting plate 195 and the inner wall of the sleeve 193 can prevent jamming when the pull rod 194 slides, ensuring that the damping spring 196 can extend and retract smoothly. At the same time, the limiting plate 195 and the inner bottom of the sleeve 193 are respectively pressed against the two ends of the damping spring 196, so that the damping spring 196 is always in a pre-compressed state, which can timely buffer the movement of the pull rod 194, effectively absorb the vibration during the lifting process, and improve the stability and comfort of the use of the hospital bed.

[0059] like Figure 2 and Figure 11 As shown, the two connecting side plates 2 are fixed to the top sides of the adjusting base 1 by connecting blocks 21 bolted to them, so that the bed can be adjusted by adjusting the bed through the connecting side plates 2. The adjusting bracket 3 is located between the two connecting side plates 2 and is bolted to the top of the adjusting base 1 by connecting blocks 21 rotatably connected by pins, so as to realize multi-angle bending adjustment of the reclining frame 6. The adjusting bracket 3 includes two S-shaped rods 311 and rotating tubes 322 respectively rotatably connected to the bottom of the two reclining frames 6. The opposite surfaces of the S-shaped rods 311 are fixedly connected to a first reinforcing rod 312. The two S-shaped rods 311 are rotatably connected to the connecting block 21 mounted on the connecting frame 18 near the bottom. The bottom end face of one of the S-shaped rods 311 is rotatably connected to a second cylinder 31. When it is necessary to adjust the angle of the upper half of the reclining frame 6, the second cylinder 31 drives the S-shaped rod 311 to rotate around the connecting block 21. The S-shaped rod 311 pushes the upper half of the reclining frame 6 to flip. The first reinforcing rod 312 enhances the structural strength of the two S-shaped rods 311 and prevents deformation.

[0060] A fixing member 321 is welded to the bottom of the rotating pipe fitting 322 near its end face, and the fixing member 321 is rotatably connected to a third cylinder 32. Support rods 323 are symmetrically welded to the rotating pipe fitting 322 near its end face, and the support rods 323 are rotatably connected to the reclining frame 6. Support rods 324 are symmetrically rotatably connected to the rotating pipe fitting 322 near its middle position. Telescopic members 325 are slidably inserted into the end faces of both support rods 324, and are rotatably connected to the bend at one end of the reclining frame 6 via the telescopic members 325. A second reinforcing rod 326 is fixedly connected to the opposite side. When it is necessary to adjust the lower half of the reclining frame 6 or the angle of the bend, the third cylinder 32 drives the rotating tube 322 to rotate through the fixing part 321. The rotating tube 322 supports the lower half of the reclining frame 6 through the support rod 323. At the same time, it pushes the bend of the reclining frame 6 to move through the support rod 324 and the telescopic part 325. The telescopic part 325 can slide adaptively with the change of the bending angle of the reclining frame 6. The second reinforcing rod 326 enhances the stability of the support rod 324 and realizes the precise bending of the reclining frame 6 at multiple angles.

[0061] The second cylinder 31 and the third cylinder 32 are located at two corresponding connecting side plates 2, and are rotatably connected to the connecting blocks 21 on the two connecting side plates 2. By rotatably connecting the second cylinder 31 and the third cylinder 32 to the connecting blocks 21 on the corresponding connecting side plates 2, the cylinders can rotate around the connecting blocks 21 when driving the adjustment bracket 3 to adapt to the rotation trajectory of the S-shaped rod 311 and the rotating tube 322, avoiding damage to the cylinders due to forced force, and ensuring that the cylinder driving force can be stably transmitted to the adjustment bracket 3, thereby improving the reliability of the bending adjustment of the reclining frame 6.

[0062] like Figures 2-4 As shown, the bed frame 4 is bolted to the top of the two connecting side plates 2 to support the patient as a whole. The two protective side frames 5 are slidably connected to both sides of the bed frame 4 and connected to the two ends of the two side plates 2 to enable different height adjustments on both sides of the bed frame 4, preventing the patient from rolling out of the bed. The reclining frame 6 is a two-section structure and is rotatably connected to the inside of the bed frame 4 to allow the patient to change positions.

[0063] like Figures 8-10 As shown, the protective side frame 5 includes two sets of U-shaped tubes 51 that slide through both sides of the frame 4. Each set of U-shaped tubes 51 has a cap 52 bolted to its top. The U-shaped tubes 51 can be hidden at their lowest point within a protective groove 41 opened in the frame 4 at the U-shaped tube 51 via the cap 52. Each set of U-shaped tubes 51 consists of three tubes, and multiple protective tubes 53 are welded equidistantly inside. A stabilizing frame 54 is slidably fitted onto the outer wall of each U-shaped tube 51 located away from the middle, and the stabilizing frame 54 is bolted to the connecting side plate 2. When protection is required, the drive mechanism... The drive mechanism 55 drives the middle U-shaped tube 51 to rise through the conical tooth block 511. The middle U-shaped tube 51 drives the two U-shaped tubes 51 to rise synchronously through the protective tube 53, forming a protective barrier to prevent the patient from rolling down. When protection is not required, the drive mechanism 55 drives the U-shaped tube 51 to fall down until the cap 52 is flush with the surface of the bed frame 4. The U-shaped tube 51 is hidden in the protective groove 41, eliminating the protruding structure. The stabilizer 54 guides and stabilizes the two U-shaped tubes 51, ensuring that the U-shaped tube 51 does not deviate when rising and falling, and improving the reliability of the protective side frame 5.

[0064] Each U-shaped tube 51 located in the middle of a set is connected to a drive mechanism 55 via a beveled tooth block 511 on its outer wall. The drive mechanism 55 includes a mounting plate 551 installed on the end face of the connecting side plate 2. A motor 552 is bolted to the top of the mounting plate 551 near one end. A drive wheel 553 is fixedly connected to the output shaft end face of the motor 552. The drive wheel 553 is driven to a driven wheel 555 via a transmission belt 554 sleeved on its outer wall. A drive shaft 556 is interference-fitted to the inner wall of the driven wheel 555. A bevel gear 557 is fixedly connected to the end face of the drive shaft 556, and the bevel gear 557 is connected to the U-shaped tube 51 via the beveled tooth block 511. The U-shaped tube 51 and the drive mechanism 55 are fixed to the connecting side plate 2 via the mounting plate 551. After the motor 552 is started, the output shaft drives the drive wheel 553 to rotate. The drive wheel 553 drives the driven wheel 555 and the drive shaft 556 to rotate via the transmission belt 554. The drive shaft 556 drives the bevel gear 557 to rotate. The bevel gear 557, through meshing with the bevel gear block 511, converts the rotational motion into the linear lifting motion of the U-shaped tube 51, realizing the height adjustment of the protective side frame 5. Through the cooperation of gear transmission and belt transmission, the driving force is ensured to be transmitted smoothly and accurately. The lifting height of the U-shaped tube 51 can be controlled according to the needs of different protection scenarios.

[0065] like Figures 1-12 As shown, an adjustable hospital bed frame suitable for dental consultations and its usage method include the following steps:

[0066] S1. Bed movement and initial positioning: Push the bed frame 4 and move the bed to an area with lighting and power interface by adjusting the rollers of the bottom moving seat 11 of the base 1, or push the portable dental treatment machine to the side of the bed. After the movement is completed, lock the rollers to ensure that the bed is fixed in position and avoid displacement during use.

[0067] S2. Overall Height Adjustment (Matching Doctor's External Position): Depending on whether the dentist chooses to perform tooth extraction standing or sitting, the first cylinder 12 is activated. The first cylinder 12 drives the rod to extend and retract, moving the crossbar 13 and side rod 14. The side rod 14 pulls the C-shaped rod 16 around the side wall of the moving seat 11 through the connecting pipe 15. The C-shaped rod 16 drives the connecting side plate 2 and the bed frame 4 to rise and fall through the reinforcing shaft 17 and the connecting frame 18. At the same time, the reinforcing shaft 17 pulls the pull rod 194 of the reinforcing component 19, causing the limiting plate 195 to compress the damping spring 196, buffering the impact of the rise and fall, until the bed frame 4 reaches the operating plane of the doctor's elbow, and the first cylinder 12 is closed.

[0068] S3. Adjusting the posture of the reclining frame (exposing the oral cavity): Adjust the patient's position according to the needs of the treatment and adjust the angle of the reclining frame 6: If treatment of the upper teeth is required, activate the second cylinder 31. The second cylinder 31 drives the S-shaped rod 311 to rotate around the connecting block 21. The S-shaped rod 311 pushes the upper half of the reclining frame 6 to rotate to the target angle, so that the patient's head is in a backward tilted position. Then, close the second cylinder 31. If treatment of the lower teeth is required, activate the third cylinder 32. The third cylinder 32 drives the rotating tube 322 to rotate through the fixing part 321. The rotating tube 322 supports the lower half of the reclining frame 6 through the support rod 323. Adjust the leg support angle to prevent the patient from sliding down due to the back being raised and ensure that the head position is relatively fixed. At the same time, the support rod 324 drives the telescopic part 325 to push the bent part of the reclining frame 6 to move until a sitting position is reached. Then, close the third cylinder 32.

[0069] S4. Adjustment of Protective Side Frame (to Free Up Operating Space): Control the raising and lowering of the protective side frame 5 according to the required operating space for treatment: Before treatment begins, to facilitate the doctor's approach, reverse the motor 552 to drive the U-shaped tube 51 to descend until the cap 52 is flush with the surface of the bed frame 4, and the U-shaped tube 51 is hidden in the protective groove 41. Then, turn off the motor 552. At this time, the doctor can place both legs under the side of the bed, with their body close to the edge of the bed, and the mobile phone cable of the portable treatment device can cross the edge of the bed without obstruction. After treatment, start the motor 552 of the drive mechanism 55. The motor 552 drives the driven wheel 555 and the drive shaft 556 to rotate through the drive wheel 553 and the transmission belt 554. The drive shaft 556 drives the bevel gear 557 to mesh with the bevel gear block 511 of the U-shaped tube 51, driving the U-shaped tube 51 to rise along the stabilizer 54 to form a protective barrier. Then, turn off the motor 552.

[0070] S5. Reset after use: After the oral consultation, start the third cylinder 32 and the second cylinder 31 in reverse order to restore the bed frame 6 to a horizontal state; start the first cylinder 12 in reverse order to lower the bed frame 4 to the lowest height; start the motor 552 in reverse order to completely hide the protective side frame 5 in the protective groove 41; finally, unlock the rollers, move the bed to the storage position and lock the rollers.
