DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] like Figures 1 to 6As shown, the present invention provides a walker for elderly services, including an auxiliary leg 1, one side of the auxiliary leg 1 is fixedly connected to a cross bar 2, a motor 3 is arranged inside the cross bar 2, the output shaft end of the motor 3 is rotatably connected to a first bevel gear 4, the first bevel gear 4 is meshed with a second bevel gear 6, the first bevel gear 4 is rotatably connected to a rotating shaft 5 on a side away from the motor 3, a screw rod 7 is fixedly connected to the bottom of the second bevel gear 6, the outer ring of the screw rod 7 is meshed with a fixed sleeve 8, the outer ring of the screw rod 7 is fixedly connected to an extended top sleeve 9, the bottom of the auxiliary leg 1 is fixedly connected to an inner sleeve 10, the inner part of the inner sleeve 10 is fixedly connected to an electric push rod 11, the side of the electric push rod 11 away from the inner sleeve 10 is fixedly connected to a movable column 12, a special-shaped clamping block 13 is arranged inside the movable column 12, one side of the special-shaped clamping block 13 is movably connected to a clamping ring 14, and the bottom of the clamping ring 14 is fixedly connected to a universal wheel 15.

[0023] By turning on the motor 3, the motor 3 drives the first bevel gear 4 when it rotates, and the first bevel gear 4 drives the second bevel gear 6 synchronously when it rotates, so that the screw rod 7 fixedly connected to the second bevel gear 6 can rotate within the setting of the fixed sleeve 8, so that the overall extension top sleeve 9 can be extended upward or lowered downward, so that the auxiliary leg can be adjusted accordingly according to the height of the elderly, which is convenient for the elderly to use better. The movable column 12 is pushed downward by the setting of the electric push rod 11, so that the special-shaped block 13 inside the movable column 12 can be expanded or tightened, so that The special-shaped clamping block 13 can fix the clamping ring 14 on the top of the universal wheel 15. One side of the special-shaped clamping block 13 is rotatably connected to the inside of the inner sleeve 10 through a rotating shaft, so that when the special-shaped clamping block 13 pushes the movable column 12 through the electric push rod 11, the special-shaped clamping block 13 can adjust the angle in the inner sleeve 10, so that the special-shaped clamping block 13 can fix the clamping ring 14 on the top of the universal wheel 15. Through the detachable design, the universal wheel can be quickly replaced to avoid the loss of anti-slip function due to long-term wear of the fixed universal wheel, thereby ensuring the safety of the elderly when using the walker.

[0024] like Figure 3 , Figure 5 As shown, one side of the special-shaped block 13 is rotatably connected to the inside of the inner sleeve 10 via a rotating shaft, a groove adapted to the special-shaped block 13 is provided inside the movable column 12, a groove adapted to the first bevel gear 4 is provided on one side of the extended top sleeve 9, one side of the fixed sleeve 8 is fixedly connected to the inside of the auxiliary leg 1, a rotating rod 16 is provided on one side of the auxiliary leg 1, and a rotating handle 17 is rotatably connected to the surface of the rotating rod 16.

[0025] The above scheme is adopted: one side of the special-shaped block 13 is rotatably connected with the inside of the inner sleeve 10 through the rotating shaft. This design enables the special-shaped block 13 to flexibly adjust the angle inside the inner sleeve 10 when the electric push rod 11 pushes the movable column 12. In this way, the special-shaped block 13 can effectively fix the clamping ring 14 on the top of the universal wheel 15. A groove adapted to the special-shaped block 13 is provided inside the movable column 12. This adaptive groove design facilitates the special-shaped block 13 to adjust the angle more smoothly, ensuring the stable function of its function. A groove adapted to the first bevel gear 4 is provided on one side of the extended top sleeve 9. This special groove design can effectively ensure that the first bevel gear 4 will not be blocked by the extended top sleeve 9 when rotating, so that the entire transmission process proceeds smoothly without jamming or failure. One side of the fixed sleeve 8 is fixedly connected to the inside of the auxiliary leg 1. This firm connection method enables the screw rod 7 to rotate according to the rotation of the screw rod 7. The fixing sleeve 8 is set to accurately raise or lower the operating position, thereby effectively adjusting the overall height of the auxiliary leg 1, better adapting to the use needs of different elderly people, and providing them with comfortable and safe walking assistance. A rotating rod 16 is set on one side of the auxiliary leg 1. Through the ingenious setting of the rotating rod 16, it can provide good rotation support and guidance for the rotating handle 17, so that the rotating handle 17 can be rotated more easily and smoothly, thereby driving the overall seat cushion 19 device to smoothly realize the action of lowering or folding, meeting the rest needs of the elderly during walking, and improving the practicality and convenience of the walker. For example, when the elderly need to sit down and rest, they only need to easily turn the rotating handle 17 to put down the seat cushion 19; when the seat cushion 19 is not needed, turn the rotating handle 17 again to fold it up. The operation is simple and efficient. When adjusting the height of the auxiliary leg 1, the screw rod 7 can rise or fall smoothly under the constraint of the fixing sleeve 8, ensuring the accuracy and stability of the height adjustment.

[0026] like Figure 3 , Figure 6 As shown, a spring member 18 is fixedly connected to the bottom of the rotating handle 17, a seat cushion 19 is fixedly connected to one side of the spring member 18, a bottom block 20 is rotatably connected to one side of the seat cushion 19, a connecting belt 21 is rotatably connected to the side of the bottom block 20 close to the seat cushion 19, a protective cover 22 is provided on the surface of the spring member 18, and a strong magnet 25 is fixedly connected to one side of the connecting belt 21.

[0027] The above scheme is adopted: the bottom of the handle 17 is fixedly connected with a spring member 18 by rotating it. Such a design enables the corresponding action to be achieved with the help of the elastic tension or thrust of the spring member 18. Specifically, the spring member 18 can be effectively pulled to achieve the good effect of facilitating the opening or folding of the seat cushion 19. One side of the spring member 18 is fixedly connected with the seat cushion 19. Through such a design of the seat cushion 19, when the elderly need to rest, the seat cushion 19 can provide a comfortable resting place for them. This comfortable design can assist the elderly to take a short rest better, so that they can relieve fatigue in time during walking. One side of the seat cushion 19 is rotatably connected with a bottom block 20. Through the setting of the bottom block 20, it is very convenient to connect with the seat cushion 19. The side of the bottom block 20 close to the seat cushion 19 is rotatably connected with a connecting belt 21. In this way, the seat cushion 19 and the bottom block 20 can be opened or folded synchronously through the ingenious setting of the connecting belt 21. This design can not only provide a comfortable resting place for the elderly when they need it, but also ensure that it will not hinder the elderly when they walk. The surface of the spring member 18 is provided with a protective cover 22. The protective cover 22 can provide excellent protection for the internal spring member 18. If the spring member 18 is exposed to the outside for a long time, it is easy to be eroded by the external environment and various accidental damages, thereby causing damage, and further affecting the subsequent opening or folding of the seat cushion 19. A strong magnet 25 is fixedly connected to one side of the connecting belt 21. The strong magnet 25 can be set to make the seat cushion 19 tightly attracted and fixed to the strong magnet 25 when it is folded, so as to effectively avoid The seat cushion 19 is prevented from falling off easily while walking, thereby ensuring the normal use of the walker, and its auxiliary walking function will not be affected by the accidental falling of the seat cushion 19. When the elderly feel tired and need to rest, they only need to operate the rotating handle 17. Under the action of the spring member 18, the seat cushion 19 will be smoothly opened. When the rest is over and they continue to walk, they operate the rotating handle 17 again. The seat cushion 19 will be synchronously folded up under the drive of the connecting belt 21 and fixed by the strong magnet 25. The whole process is smooth and convenient, which provides great convenience for the use of the elderly.

[0028] like Figure 1 , Figure 6 As shown, the top of the extended top cover 9 is fixedly connected with a hand rail 23, the upper surface of the hand rail 23 is fixedly connected with a cover 24, the spring member 18 is composed of a tension spring and a fixed block, a buffer rod is arranged in the middle of the spring member 18, the connecting belt 21 is rotatably connected with the seat cushion 19 at the side away from the bottom block 20, and the strong magnet 25 is connected with the bottom of the seat cushion 19.

[0029] The above scheme is adopted: a hand support bar 23 is fixedly connected to the top of the extended top cover 9, and the setting of the hand support bar 23 makes it convenient for the elderly to bear force when walking. A sheath 24 is fixedly connected to the upper surface of the hand support bar 23, and the setting of the sheath 24 makes it convenient to achieve a comfortable effect. The material of the sheath 24 is sponge, which can make the use of the walker more comfortable. The spring member 18 is composed of a tension spring and a fixed block. The tension spring and the fixed block facilitate the spring member 18 to be better connected to the rotating handle 17, so that the spring member 18 can be rotated. The movable handle 17 is arranged to rotate, and a buffer rod is arranged in the middle of the spring member 18. The buffer rod is arranged so that a buffer effect can be achieved when the spring member 18 is used. The connecting belt 21 is rotatably connected to the seat cushion 19 on the side away from the bottom block 20, so that when the seat cushion 19 is opened or folded, the seat cushion 19 and the bottom block 20 can be synchronously opened or folded through the connecting belt 21. The strong magnet 25 is fixedly connected to the seat cushion 19, so that when the seat cushion 19 is folded, the seat cushion 19 can be fixed by the setting of the strong magnet 25 to prevent the seat cushion 19 from falling off when the elderly are walking.

[0030] The working principle and use process of the present invention: First, we turn on the motor 3, the motor 3 starts to rotate and drives the first bevel gear 4 to rotate. When the first bevel gear 4 rotates, it will drive the second bevel gear 6 meshing with it to rotate synchronously. When the second bevel gear 6 rotates, the screw rod 7 fixedly connected to its bottom will also rotate synchronously. During the rotation of the screw rod 7, it meshes and rotates inside the fixed sleeve 8, which can effectively prevent the screw rod 7 from slipping, thereby preventing the extension top sleeve 9 from falling off from the auxiliary leg 1. The rotation of the screw rod 7 will drive the extension top sleeve 9 to rise or fall, which can be adjusted according to the body shape of the elderly. The height of the walker can be flexibly adjusted, so that the walker is more diversified when used and meets the needs of elderly people of different heights. When the elderly need to rest during walking, the seat cushion 19 can be opened, which can provide a short resting place for the elderly. After the seat cushion 19 is not in use, the seat cushion 19 drives the rotating handle 17 to rotate on the rotating rod 16, so that the seat cushion 19 is folded, and the seat cushion 19 is fixed by a strong magnet 25, so that the seat cushion 19 will not fall off during walking, so as not to affect the normal use of the walker. After the traveler has been used for a long time, the surface of the universal wheel 15 at the bottom is prone to wear, which will reduce the anti-skid effect of the universal wheel 15. At this time, the movable column 12 is pushed downward by the electric push rod 11, so that the special-shaped block 13 inside the movable column 12 shrinks inward, so that the clamping ring 14 can be quickly driven to remove the universal wheel 15, and then the universal wheel 15 can be replaced. This can avoid the instability caused by the reduction of the anti-skid function of the universal wheel 15 during use. The top of the extended top sleeve 9 is fixedly connected to the hand support rod 23. The upper part of the hand support rod 23 A sheath 24 is fixedly connected to the surface, and the material of the sheath 24 is sponge. This sponge material can provide good touch and cushioning effect, making the elderly feel more comfortable when using the walker. Traditional walkers have many shortcomings in design and relatively single functions. For example, the height of the walker cannot be adjusted according to the height of different elderly people, and it cannot adapt well to individual differences. Moreover, the fixed universal wheel 15 is not only inconvenient for subsequent replacement, but also easy to cause the need to replace the entire walker when there is a problem with the universal wheel 15, resulting in a great waste.

[0031] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
