Description

Technical Field

[0001] The invention belongs to the technical field of medical equipment, and in particular relates to a lifting and lowering machine. Background Art

[0002] A transfer machine is a medical device that helps people with limited mobility solve the problem of moving from wheelchairs to sofas, beds, toilets, chairs, etc., as well as a series of life problems such as going to the toilet and taking a bath.

[0003] At present, the existing transfer machine only relies on rollers to support the bottom of the transfer machine, and the contact area between the bottom of the transfer machine and the ground is small. During use, when a heavy user is on board, the transfer machine has insufficient bearing capacity, which can easily cause damage to the transfer machine. In addition, the rollers are prone to free sliding, which makes the overall stability of the transfer machine poor, which is dangerous to use and affects the safe use of the transfer machine.

The second spring is arranged inside the bent pipe, and the two ends of the upper end of the second spring are fixedly connected to the inner wall of the bent pipe and the upper end of the second piston rod respectively.

[0036] See also Figure 1-Figure 11 As shown, the present invention is a lifting type shifting machine, comprising a fixed base frame 1, two brake front wheels 2 are relatively installed on the bottom front side of the fixed base frame 1, two first universal wheels 3 are relatively installed on the bottom rear side of the fixed base frame 1, two fixed rods 4 are relatively fixed on the top front side of the fixed base frame 1, a lifting sleeve 5 is movably sleeved on the outer side of the fixed rod 4, an electric push rod 6 is arranged between one side of the outer wall of the lifting sleeve 5 and the fixed base frame 1, two fixed plates 7 are relatively fixed on the rear side of the outer wall of the lifting sleeve 5, a rotating rod 8 is rotatably arranged between two adjacent fixed plates 7, and a seat assembly 9 is fixed on the outer wall of the rotating rod 8. Through the extension and contraction of the electric push rod 6, combined with the active cooperation of the lifting sleeve 5 and the fixed rod 4, it is convenient to flexibly adjust the up and down movement of the lifting sleeve 5, thereby driving the seat assembly 9 to move synchronously, so as to achieve the purpose of lifting the shifting machine and facilitate use. An auxiliary support assembly is arranged on the fixed base frame 1, and a limited position assembly is arranged on one side of the auxiliary support assembly. The auxiliary support assembly includes:

[0037] The support shaft 10 has two through slots extending relatively through the rear side of the fixed base frame 1. The support shaft 10 is rotatably arranged inside the through slots. The lower end of the support shaft 10 passes through the bottom of the fixed base frame 1 and is connected to a movable plate 12. A second universal wheel 13 is installed at the bottom of the movable plate 12.

[0038] The auxiliary support assembly also includes a gear 11, a support plate 14, a first motor 15, a rotating shaft 16, a winding roller 17, a steel rope 18, a support rod 19, a rack 20, a fixed block 21 and a first spring 22. The gear 11 is sleeved on the support shaft 10, and the two support plates 14 are relatively fixed on the inner wall of the fixed base frame 1 in the vertical direction. The first motor 15 is installed on the top of the support plate 14 on the lower side. The output end of the first motor 15 is connected to the rotating shaft 16, and the upper end of the rotating shaft 16 is rotatably connected to the upper support plate 14. The winding roller 17 is sleeved on the rotating shaft 16.

[0039] Two steel ropes 18 are relatively fixed on the winding roller 17, the support rod 19 is fixed on the lower side of the inner part of the through groove, the rack 20 is slidably mounted on the support rod 19, and the rack 20 is meshed with the gear 11, the fixed block 21 is fixed on the top of the rack 20, and a pulley block 30 is provided on the front side of the inner wall of the through groove. The end of the steel rope 18 away from the winding roller 17 passes through the pulley block 30 and is connected to the fixed block 21. The first spring 22 is mounted on the outside of the support rod 19, and the two ends of the first spring 22 are respectively fixedly connected to the front end of the rack 20 and the inner wall of the through groove.

[0040] In the above structure, the first motor 15 is used to drive the rotating shaft 16 to rotate, thereby driving the winding roller 17 to rotate synchronously to reel in the steel rope 18. Under the sliding cooperation between the rack 20 and the support rod 19, the rack 20 is pulled to move along the direction of the support rod 19. Combined with the meshing action of the rack 20 and the gear 11, and the rotation installation of the support shaft 10, the support shaft 10 is driven to rotate. As the support shaft 10 rotates, the movable plate 12 is driven to rotate outward, so that the movable plates 12 on both sides extend to the outside of the fixed base frame 1, which effectively improves the supporting effect of the bottom of the transfer machine and ensures the stability of the transfer machine during use.

[0041] The limiting assembly includes a transverse plate 23, a first piston rod 24, a bent pipe 25, a second piston rod 26, a rubber sheet 27, a support frame 28 and a second spring 29. The transverse plate 23 is fixed between the two racks 20, the support frame 28 is fixed to the inner side of the fixed base frame 1, the bent pipe 25 is embedded in the support frame 28, the first piston rod 24 and the second piston rod 26 are both movably cooperated with the bent pipe 25, the front end of the first piston rod 24 is fixedly connected to the transverse plate 23, and the lower end of the second piston rod 26 is fixedly connected to the rubber sheet 27.

[0042] The cross-sections of the first piston rod 24 and the second piston rod 26 are both T-shaped structures. The inside of the curved tube 25 is filled with hydraulic oil, and the hydraulic oil is filled between the first piston rod 24 and the second piston rod 26. The second spring 29 is arranged inside the curved tube 25, and the two ends of the upper end of the second spring 29 are fixedly connected to the inner wall of the curved tube 25 and the upper end of the second piston rod 26 respectively.

[0043] Through the cooperation of the first piston rod 24 and the second piston rod 26 with the curved tube 25, combined with the elastic effect of the second spring 29 and the hydraulic oil filled in the curved tube 25, it is convenient to drive the rubber sheet 27 away from or close to the ground when the rack 20 is adjusted during use, so as to increase the friction between the bottom of the transfer machine and the ground, ensure the stability of the transfer machine, and avoid the free sliding of the transfer machine.

[0044] An auxiliary wheel 31 is installed at the bottom of the support plate 14 on the lower side, and a second motor 32 is installed at the bottom of the fixing plate 7 on the lower side through a bracket. The output end of the second motor 32 is connected to the lower end of the rotating rod 8.

[0045] The seat assembly 9 includes a seat plate, a backrest, a handle and a grip. The two seat plates are fixedly connected to the rotating rod 8. The backrest and the seat plate are fixed by a connecting rod. The handle is fixed to the back surface of the backrest, and the grip is fixed to the front side of the outer wall of the lifting sleeve 5.

[0046] Example:

[0047] In the initial state, the rack 20 is at the rearmost side, at which time the movable plate 12 drives the second universal wheel 13 to be stabilized at the lower side of the fixed base frame 1, and the rubber sheet 27 is in contact with the ground;

[0048] During the use of the transfer machine, the first motor 15 is first started, and the first motor 15 drives the rotating shaft 16 to rotate. During the rotation of the rotating shaft 16, the winding roller 17 is driven to rotate, and combined with the pulley block 30, the purpose of stably winding the steel rope 18 is achieved. As the steel rope 18 is wound onto the winding roller 17, the fixed block 21 is pulled to move synchronously, and combined with the sliding cooperation between the rack 20 and the support rod 19, the rack 20 is driven to move synchronously in the direction of the pulley block 30;

[0049] During the movement of the rack 20, the meshing action of the rack 20 and the gear 11 drives the support shaft 10 to rotate. With the rotation of the support shaft 10, the two movable plates 12 are driven to rotate toward the two sides of the fixed base frame 1 respectively, thereby driving the second universal wheel 13 to move synchronously until the movable plates 12 on both sides rotate to a state of extending outward, thereby effectively improving the support stability of the bottom of the transfer machine, and solving the problem that the existing transfer machine only relies on rollers to support the bottom of the transfer machine, and the contact area between the bottom of the transfer machine and the ground is small. During use, when a heavy user is on board, the bearing capacity of the transfer machine is insufficient, which is easy to cause damage to the transfer machine;

[0050] In the process of adjusting the rack 20 to move, the first piston rod 24 is driven to move toward the outside of the curved pipe 25 under the action of the cross plate 23. Under the action of negative pressure, the hydraulic oil inside the curved pipe 25 is pumped toward the lateral part of the curved pipe 25. Combined with the elastic action of the second spring 29, the second piston rod 26 is pulled to move upward along the vertical part of the curved pipe 25, thereby driving the rubber sheet 27 upward from the ground, so as to facilitate the subsequent movement of the transfer machine.

[0051] When the user moves onto the transfer machine, the second motor 32 is first driven to drive the rotating rods 8 on both sides to rotate synchronously, thereby driving the seat plates and backrests on both sides to move closer to each other until the two seat plates and the two backrests are attached together to form a seat assembly 9, which is convenient for the user to sit and lean.

[0052] It should be further explained that the installation structure, connection method or setting method of each component in the present invention are all common mechanical methods, and they can be implemented as long as they can achieve their beneficial effects. At the same time, the electric push rod 6, the first motor 15 and the second motor 32 in the present invention are all purchased on the market, and technical personnel in this field can install and use them as required.
