[0028] 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.

[0029] like Figures 1 to 8As shown, this utility model provides a reclining nursing wheelchair, including a wheelchair body 1, two footrests 2, a footrest lifting mechanism 3, a backrest 4, a backrest support mechanism 5, and a locking mechanism 6 for locking the backrest 4. The footrest lifting mechanism 3 is hinged to the front end of the wheelchair body 1, and the two footrests 2 are symmetrically mounted on the footrest lifting mechanism 3. The backrest 4 is hinged to the rear end of the wheelchair body 1, and the backrest support mechanism 5 is mounted on one side of the backrest 4. The locking mechanism 6 is mounted on the wheelchair body 1, and the backrest support mechanism 5 is connected to the locking mechanism 6. The structure 5 includes a fixed base 8 and two identical support components. The fixed base 8 is fixed to the backrest 4. Both sides of the fixed base 8 are hinged with hinge joints 12. The two support components are symmetrically arranged on one side of the backrest 4. Each support component includes a fixed cylinder 9, a telescopic cylinder 10, and an adsorption fixing member 11 for fixing the backrest 4 when it is laid flat. The fixed cylinder 9 is fixedly connected to the bottom end of the corresponding hinge joint 12. The telescopic cylinder 10 is threadedly connected to the outer wall of the fixed cylinder 9. The adsorption fixing member 11 is fixedly connected to the end of the outer wall of the telescopic cylinder 10 away from the fixed cylinder 9.

[0030] In use, the patient sits on the wheelchair body 1. When the patient needs to lie down for examination or care, two locking mechanisms 6 are provided, and the two locking mechanisms 6 have the same structure. The two locking mechanisms 6 are respectively connected to two support components. The locking mechanism 6 includes a guide slider 61, a locking screw 62, and a handle 63. The backrest 4 has a sliding groove 64 on both sides, and the wheelchair body 1 has a guide groove 65 on both sides. A circular receiving groove 66 is formed on one side of each of the two guide grooves 65. The guide slider 61 is slidably disposed in the sliding groove 64. The locking screw 62 is threadedly connected to the inside of the guide slider 61, and one end of the locking screw 62 passes through the sliding groove 64 and the guide groove 65 in sequence and extends into the inside of the circular receiving groove 66. The handle 63 is fixedly connected to the end of the locking screw 62 and is located inside the circular receiving groove 66.

[0031] The handle 63 can rotate 360 ​​degrees within the circular receiving groove 66. When the handle 63 is rotated to be parallel to the guide groove 65, the backrest 4 is released from its locked state. When the handle 63 is rotated to any other angle, the backrest 4 is locked.

[0032] Initially, the backrest 4 is locked. When the patient needs to lie down, the lock on the backrest 4 needs to be released. At this time, rotate the handle 63 until it is parallel to the guide groove 65, then push the handle 63 and its fixing locking screw 62 out of the guide groove 65, causing the handle 63 to disengage from the circular receiving groove 66. This allows the locking screw 62 and the guide slider 61 to slide along the slide groove 64, thereby releasing the lock on the backrest 4. After rotating the backrest 4 to a flat position, unfold the backrest support mechanism 5 and ensure it is stable. Then, rotate the telescopic cylinder 10 from its fixed position... The cylinder 9 is removed, and then the adsorption fixing part 11 is pressed against the ground and adsorbed to the ground, so that the backrest 4 is placed stably, so as to avoid the backrest 4 shaking when the patient lies down, thereby avoiding the patient's psychological tension or the impact of the backrest 4 shaking on the examination and nursing work. When the patient lies down on the wheelchair body 1 and the backrest 4, he puts his feet up, and after the footrest lifting mechanism 3 lifts the footrest 2, the patient places his legs on the footrest lifting mechanism 3. After the patient completes the entire lying down step, he can remain in a comfortable state to receive examination or nursing.

[0033] When the patient needs to sit up, the procedure is reversed. First, the footrest 2 is lowered, allowing the patient's feet to rest naturally on it. Then, the backrest support mechanism 5 is retracted, and the backrest 4 is rotated to its initial angle. The locking mechanism 6 then locks the backrest 4 to support the patient's back, ensuring safety and comfort when sitting up. The entire process is simple and easy to perform, greatly reducing the workload of nursing staff while improving the patient's nursing experience. It not only improves nursing efficiency but also enhances patient comfort and satisfaction.

[0034] Furthermore, on the side of the backrest 4 near the support assembly, there are two strip-shaped channels 67 that are respectively connected to two slide grooves 64. A hinge seat 68 is fixedly connected to the side of the guide slider 61 facing the strip-shaped channel 67. A hinge rod 69 is hinged inside the hinge seat 68. A ring 7 is rotatably connected to the outside of the telescopic cylinder 10. The other end of the hinge rod 69 is rotatably connected to the ring 7.

[0035] The slide 64 has two positioning grooves 70 inside, and the locking screw 62 is threadedly connected to the positioning grooves 70.

[0036] One of the positioning grooves 70 is located at the bottom of the slide groove 64, and the locking screw 62 is threadedly connected to the positioning groove 70 to fix it, thereby locking the relative position of the backrest 4 and the seat body. When the angle of the backrest 4 needs to be adjusted, the operator rotates the handle 63 until it is parallel to the guide groove 65 while simultaneously rotating the locking screw 62. This unscrews the locking screw 62 from the positioning groove 70, releasing the lock. By pushing or pulling the locking screw 62, the hinge seat 68 is moved, thereby adjusting the angle of the hinge rod 69. This allows the hinge seat 68 to move along the strip groove 67, while the other end of the hinge rod 69 locks the telescopic cylinder 10 in place. After adjustment, the locking screw 62 is aligned with another positioning groove 70 and screwed into it to lock the angle of the backrest 4. When the backrest 4 is laid flat, the position of the other positioning groove 70 is where the hinge rod 69 pushes the telescopic cylinder 10 to a 90-degree unfolded position. The hinge rod 69 assists in supporting the telescopic cylinder 10, thereby improving its stability. Furthermore, the hinge rod 69 automatically locks when the backrest 4 is tilted to a certain angle, preventing the backrest 4 from accidentally falling over and protecting the patient's safety. The hinge rod 69 is linked to the movement of the telescopic cylinder 10. When the locking mechanism 6 is unlocked, if the telescopic cylinder 10 is fully extended, the hinge rod 69 can automatically extend to ensure the stability of the backrest 4. When the telescopic cylinder 10 begins to retract, the hinge rod 69 retracts and pushes the fixed slider to reset. This design not only improves the safety of using the nursing wheelchair but also makes it more convenient for caregivers to operate, reducing the risk of injury to the patient.

[0037] The adsorption fixing component 11 includes a suction cup 111 and a fixing tube 112. The fixing tube 112 is slidably connected inside the telescopic cylinder 10 and extends to the outside of the telescopic cylinder 10. A piston 113 is fixedly connected to one end of the fixing tube 112 inside the telescopic cylinder 10. The piston 113 is axially sealed to the telescopic cylinder 10. A through hole 114 is opened on the side wall of the fixing tube 112 to connect the fixing tube 112 and the telescopic cylinder 10. The suction cup 111 is fixedly connected to one end of the fixing tube 112 away from the telescopic cylinder 10. Multiple air ports 115 are opened between the suction cup 111 and the fixing tube 112. A spring 116 is sleeved on the outside of the fixing tube 112. The two ends of the spring 116 abut against the piston 113 and the telescopic cylinder 10, respectively.

[0038] The suction cup 111 is connected to an external air source through the air port 115. One end of the fixing tube 112 is fixedly connected to the piston 113 inside the telescopic cylinder 10, achieving an axial seal with the cylinder body. When the suction cup 111 contacts the ground, its interior can be sealed, adhering tightly to the ground to initially fix the backrest 4 and prevent it from moving. Subsequently, when the staff presses on the patient or the patient lies down, the telescopic cylinder 10 is pressed down by the weight of the backrest 4 and stretches the spring 116, creating an adsorption force between the telescopic cylinder 10 and the fixing tube 112. This draws the remaining air in the suction cup 111 into the fixing tube 112 through the air port 115, and then into the telescopic cylinder 10 through the through hole 114, making the suction cup 111 adhere more tightly to the ground, achieving secondary adsorption and fixation, and ensuring the stability of the backrest 4. When the patient's upper body is raised, the backrest 4 loses pressure, the spring 116 returns to its original position after losing tension, and moves the telescopic cylinder 10 upward, releasing the air source inside. The suction cup 111 then separates from the ground. During the extension and retraction of the telescopic cylinder 10, the piston 113 maintains a good seal to prevent air leakage and ensure the durability of the adsorption effect. The design of the entire adsorption fixing component 11 ensures both ease of operation and reliability, providing a safe and stable nursing environment for the patient.

[0039] The footrest lifting mechanism 3 includes two supports 31. Two mounting slots 32 are symmetrically opened on the side of the wheelchair body 1 away from the backrest 4. One end of each of the two supports 31 is rotatably set in the two mounting slots 32. Telescopic slots 33 are opened on both sides of the wheelchair body 1, which are respectively connected to the two mounting slots 32. Both ends of each of the two supports 31 are fixedly connected to protrusions 34, which are slidably connected in the telescopic slots 33. Two footrests 2 are respectively installed at the bottom of the two supports 31. A leg support plate 35 is connected between the two supports 31.

[0040] During the use of the footrest lifting mechanism 3, when it is necessary to lift the footrest 2, the bracket 31 can be rotated to be on the same horizontal line as the telescopic groove 33, so that the protrusion 34 slides along the inside of the telescopic groove 33, thereby driving the bracket 31 to extend into the telescopic groove 33, thus limiting the position of the bracket 31. Then, the push plate can be adjusted to a flat position, so that the patient can lay flat with both feet flat for examination and care. At the same time, the presence of the leg support plate 35 ensures stable support for the user's legs and prevents the legs from slipping during movement.

[0041] Storage boxes 13 are mounted on both sides of the wheelchair body 1. The design of the storage boxes 13 takes into account the daily needs of wheelchair users, providing convenient storage space for items. Its opening design makes it easy for users to put in and take out items, which not only improves the comfort of using the wheelchair, but also enhances its functionality, making the wheelchair more suitable for care and daily use.

[0042] like Figure 5As shown, a pulley mechanism is also provided on the fixed base 8. The pulley mechanism includes two telescopic rods 14 hinged inside the fixed base 8. The two telescopic rods 14 are located between the two support components, and the bottom of each of the two telescopic rods 14 is rotatably connected to a pulley 15.

[0043] This utility model allows for the selection of either a roller sliding mechanism or a backrest support mechanism 5, depending on the situation. When the patient does not need to be moved for nursing examinations, the backrest support mechanism 5 can be deployed to make the backrest 4 more stable and less prone to movement. If the patient's condition changes during transport, the backrest 4 can be laid flat, and the roller sliding mechanism can be deployed. By adjusting the length of the telescopic rod 14, the roller sliding mechanism 15 can be moved to touch the ground, allowing the wheelchair to be laid flat so that the patient can lie down in time, ensuring the patient's safety and reaching the treatment location as quickly as possible.

[0044] The above embodiments are merely exemplary embodiments of this application and are not intended to limit this application. The scope of protection of this application is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to this application within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of this application.
