Description

Technical Field

[0001] The present invention relates to the technical field of nursing chairs, and particularly to a nursing chair for patients with limited mobility. Background Art

[0002] Limited mobility generally refers to a person who is unable to freely perform normal physical activities due to a certain physical condition or reason, which may be caused by old age, illness, disability or other health problems. Therefore, such people need to use a nursing chair. For this reason, a nursing chair for patients with limited mobility is proposed.

[0003] Most of the existing nursing chairs are fully automatic and manual when moving. Although the fully automatic one can make the nursing chair move automatically, the battery life is relatively short. While the manual one can make the battery life relatively longer, it is relatively laborious. And most of the existing nursing chairs cannot effectively provide massage treatment for patients. When sitting for a long time, it may cause soreness in the waist.

[0004] Therefore, the technical personnel in this field provide a nursing chair for patients with limited mobility to solve the problems raised in the above background art. Summary of the Invention

[0005] (1) Technical Problems to be Solved

[0006] In view of the deficiencies of the prior art, the present invention provides a nursing chair for patients with limited mobility. The nursing chair drives a threaded rod to rotate through a servo motor arranged, and then the threaded block moves when the threaded rod rotates, so that the threaded block drives an electric slide rail to move when moving, and then an electric slider drives a mounting plate to move on the electric slide rail, and then an electric telescopic rod drives a massage ball to work, so that the massage ball massages the back of the patient through a nylon net, solving the problems that most of the existing nursing chairs are fully automatic and manual when moving. Although the fully automatic one can make the nursing chair move automatically, the battery life is relatively short. While the manual one can make the battery life relatively longer, it is relatively laborious. And most of the existing nursing chairs cannot effectively provide massage treatment for patients. When sitting for a long time, it may cause soreness in the waist.

[0036] Next, the technical solutions in the specific embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the specific embodiments of the present invention. Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, rather than all of the specific embodiments. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. Specific embodiments:

[0038] As Figures 1-5 shown, the specific embodiments of the present invention provide a nursing chair for patients with limited mobility, including a frame 1. A seat cushion 9 is arranged in the middle of the inner wall of the frame 1. A support plate 2 is arranged at the lower end of the seat cushion 9. A placing groove 13 is opened at the center of the upper surface of the support plate 2. Boosting motors 11 are fixedly connected to the middle parts of both sides of the upper surface of the support plate 2. Driven gears 12 are fixedly connected to the output ends of the boosting motors 11. Movable wheels 4 are arranged at the middle parts of the outer walls of both sides of the frame 1. One ends of the movable wheels 4 close to the frame 1 penetrate through the frame 1 and are fixedly connected to driving gears 10;

[0039] At the upper end of the seat cushion 9, there is a backrest 7. On one side of the inner top surface of the backrest 7, a servo motor 19 is fixedly connected. The output end of the servo motor 19 is fixedly connected with a threaded rod 17. On the side of the inside of the backrest 7 far from the threaded rod 17, a slide rod 15 is arranged. A threaded block 18 is sleeved on the rod body of the threaded rod 17. On the outer wall of the side of the threaded block 18 close to the middle of the backrest 7, an electric slide rail 20 is fixedly connected. An electric slider 23 slides inside the electric slide rail 20. On the outer wall of the front end of the electric slider 23, a mounting plate 22 is fixedly connected. On the outer wall of the front end of the mounting plate 22, two electric telescopic rods 24 are fixedly connected. The output end of the electric telescopic rod 24 is fixedly connected with a massage ball 21;

[0040] This nursing chair helps to improve the comfort of patients with limited mobility and promote recovery and health.

[0041] A slider 16 is sleeved on the rod body of the slide rod 15. The outer wall of the side of the slider 16 close to the middle of the backrest 7 is fixedly connected with the electric slide rail 20. By sleeving the slider 16 on the rod body of the slide rod 15 and fixedly connecting the outer wall of the side of the slider 16 close to the middle of the backrest 7 with the electric slide rail 20, the electric slide rail 20 can be better limited. At the lower end of the front outer wall of the frame 1, a footrest 3 is arranged. At the upper end of the rear outer wall of the frame 1, a handle 6 is arranged. By arranging the footrest 3 at the lower end of the front outer wall of the frame 1, the feet can be better placed. By arranging the handle 6 at the upper end of the rear outer wall of the frame 1, the nursing chair can be better pushed.

[0042] On the outer wall of the side of the movable wheel 4 far from the frame 1, an armrest 5 is arranged. By arranging the armrest 5 on the outer wall of the side of the movable wheel 4 far from the frame 1, the armrest 5 can better drive the movable wheel 4 to rotate. The lower surface of the threaded rod 17 is rotatably connected with the inner bottom surface of the backrest 7. By rotatably connecting the lower surface of the threaded rod 17 with the inner bottom surface of the backrest 7, the rotation stability of the threaded rod 17 can be effectively improved while it rotates. On the front outer wall of the backrest 7, a nylon net 8 is arranged. By arranging the nylon net 8 on the front outer wall of the backrest 7, the massage ball 21 can better massage the patient through the nylon net 8.

[0043] The driving gear 10 is meshed with the driven gear 12. By meshing the driving gear 10 with the driven gear 12, the movable wheel 4 can better rotate the output end of the booster motor 11. Inside the placement groove 13, a storage battery 14 is arranged. The storage battery 14 is electrically connected to the booster motor 11, the servo motor 19, the electric telescopic rod 24, and the electric slide rail 20. By arranging the storage battery 14 inside the placement groove 13 and electrically connecting the storage battery 14 to the booster motor 11, the servo motor 19, the electric telescopic rod 24, and the electric slide rail 20, the storage battery 14 can better provide power for them.

[0044] Working principle: When in use, the patient sits on the cushion 9, then places the feet on the footrest 3. When the patient needs to move the nursing chair, the patient manually rotates the armrest 5, which drives the movable wheel 4 to rotate. Then, the movable wheel 4 drives the driving gear 10 to rotate, so that the driving gear 10 meshes with the driven gear 12 to drive the output end of the assist motor 11 to rotate. When the assist motor 11 senses the rotation of the output end, the coil inside the assist motor 11 works and rotates synchronously with the assist motor 11, so that the assist motor 11 provides assistance when the patient rotates the movable wheel 4. Then, the servo motor 19 can be started. The servo motor 19 drives the threaded rod 17 to rotate. When the threaded rod 17 rotates, the threaded block 18 moves, so that the threaded block 18 drives the electric slide rail 20 to move. Then, the electric slider 23 drives the mounting plate 22 to move on the electric slide rail 20, and then the electric telescopic rod 24 drives the massage ball 21 to work, so as to massage the patient's back.

[0045] Although specific embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these specific embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
