Description

Technical Field

[0001] This utility model belongs to the field of medical auxiliary devices and relates to a water-medium hydraulic lifting chair. Background Technology

[0002] In recent years, my country's population has been aging rapidly, with many elderly people suffering from various ailments and experiencing mobility difficulties, making getting up, sitting down, and using the toilet major challenges. Currently, elderly people with mobility issues generally rely on themselves, canes, or medical staff for support when getting up, sitting down, or using the toilet, but most of the time they still need to do it on their own.

[0003] A Chinese utility model patent with publication number CN204500015U describes a water-medium hydraulic lifting chair, comprising a chair base, a chair back, and chair legs. The chair base and chair back are mounted on the chair legs. The chair base is characterized by having one or more chair legs mounted below it. Each chair leg assembly includes a sleeve rod and a base rod. The sleeve rod is fitted onto the outer circumference of the base rod and can slide axially along the base rod. The base rod is placed on the ground. The chair base is mounted on the sleeve rod. The sleeve rod and the base rod each have a communicating water storage cavity. When the sleeve rod slides axially onto the base rod, the two are in a movable seal. The base rod is equipped with a water supply and discharge assembly communicating with the water storage cavity.

[0004] The existing technology has the following technical defects:

[0005] While the above-mentioned technical solutions can achieve the lifting and lowering of the chair base, people with leg disabilities still need to use tools such as canes to gain leverage when getting up and sitting down. Furthermore, the lifting and lowering of the above-mentioned technical solutions can only achieve horizontal lifting and cannot provide tilt support for people. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a water-medium hydraulic lifting chair.

[0007] The water-medium hydraulic lifting chair of this utility model includes a base, a fixed foot pad at the bottom of the base, a support rod at the front of the base, and a hinge seat at the rear of the base. A hydraulic cylinder is hinged to the hinge seat, and a seat plate is hinged to the piston rod of the hydraulic cylinder. The seat plate is hinged to the bottom of the support rod.

[0008] Working process or working principle:

[0009] During use, the hydraulic cylinder operates to raise and lower the seat. Since the support rod is fixed, the lifting plate will move in an arc around the intersection point with the support rod, providing a certain support force for the user when getting up. The hydraulic cylinder uses water as its power medium, which is convenient to use.

[0010] The seat is double-folded, with the folds connected by hinges. The piston rod of the hydraulic cylinder is fixedly connected to the seat. The double folds prevent the rear half from tilting forward too much when it is raised, ensuring that the user's buttocks are always in contact with the seat, providing a certain level of support and preventing the user from sliding off due to a large tilt.

[0011] The seat is equipped with armrests, and the armrests are equipped with lifting switches. The lifting switches are connected to hydraulic cylinders. When sitting up, users can use the armrests for leverage, and users can also control the degree of seat height by themselves through the lifting switches.

[0012] The fixing feet are suction cup feet, but rubber feet or other materials can also be used to increase friction and ensure that the feet will not shift during use.

[0013] The hydraulic cylinder is a piston type.

[0014] The seat has a hole in the middle. The hole can be aligned with the toilet or the commode can be placed below the hole, making it convenient for people to use the toilet by lifting the seat.

[0015] A pressure relief valve is installed at the water inlet of the hydraulic cylinder to prevent excessive water pressure.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This utility model folds the seat so that it can tilt at a certain angle when raised and lowered, thus providing support for the user at a certain angle and making it easier for them to sit up and get up. At the same time, a hole is opened in the middle of the seat to facilitate the use of the toilet for people with mobility impairments, reducing the risk of falls when people with mobility impairments are sitting up, taking a shower, or using the toilet.

[0023] Example 1

[0024] like Figures 1-4 As shown, the water-medium hydraulic lifting chair of this utility model includes a base 7, a fixed foot pad 6 at the bottom of the base 7, a support rod 5 at the front of the base 7, a hinge seat 9 at the rear of the base 7, a hydraulic cylinder 8 hinged on the hinge seat 9, and a seat plate 3 hinged to the piston rod of the hydraulic cylinder 8. The seat plate 3 is hinged to the bottom of the support rod 5.

[0025] Working process or working principle:

[0026] When in use, the hydraulic cylinder 8 works to drive the seat plate 3 to rise and fall. Since the support rod 5 is fixed, the lifting plate will move in an arc with the intersection point with the support rod 5 as the center, providing a certain support force for the user when getting up.

[0027] Example 2

[0028] like Figures 1-4 As shown, unlike Embodiment 1, the seat 3 in this embodiment is double-folded, with the folds connected by hinges 4. The piston rod of the hydraulic cylinder 8 is fixedly connected to the seat 3. The double folds prevent the rear half from tilting forward too much when raised, ensuring that the user's buttocks remain in contact with the seat, providing support and preventing the user from slipping off due to large tilts. The seat 3 is equipped with armrests 1, and a lifting switch 10 is installed on the armrests. The lifting switch 10 is connected to the hydraulic cylinder 8. Users can use the armrests for leverage when sitting up or down, and can also control the degree of seat height by themselves using the lifting switch. The fixed foot pads 6 are suction cup pads, or rubber pads can be used to increase friction and prevent displacement during use. The hydraulic cylinder 8 is a piston type. The seat 3 has a hole 2 in the middle. The hole 2 can be aligned with the toilet or the commode can be placed below the hole 2, making it convenient for users to use the lifting seat 3.

[0029] Working process or working principle:

[0030] When in use, the hydraulic cylinder 8 works to drive the seat plate 3 to rise and fall. Since the support rod 5 is fixed, the lifting plate will move in an arc with the intersection point with the support rod 5 as the center, providing a certain support force for the user when getting up. The two folds can prevent the rear half from tilting forward too much when it is raised, so that the user's buttocks are always in contact with it, maintaining a certain support force and preventing the user from sliding directly off due to large-angle tilting.

[0031] This utility model folds the seat 3 so that it can tilt at a certain angle when raised and lowered, thereby providing support for the user at a certain tilt angle, making it easier for the user to sit up and get up. At the same time, a hole 2 is opened in the middle of the seat 3 to facilitate the use of the toilet for people with mobility impairments, reducing the risk of falls when people with mobility impairments sit up and use the toilet.

[0032] The descriptions of the orientation and relative positional relationships of the structure in this utility model, such as descriptions of front, back, left, right, up, and down, do not constitute a limitation on this utility model, but are merely for the convenience of description.
