DETAILED DESCRIPTION

[0022] The following embodiments of the technical solution of the present invention are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and are therefore only used as examples, and cannot be used to limit the protection scope of the present invention.

[0023] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by those skilled in the art to which the present invention belongs.

[0024] Embodiment 1

[0025] like Figures 1 to 3 As shown, a specific embodiment of the present invention provides an auxiliary training escalator that is convenient to adjust. The device is used in limb rehabilitation training. Different training trajectories can be provided for different rehabilitation stages to meet the patient's exercise requirements at different rehabilitation stages. Specifically, it includes a base 100 and an escalator assembly. The upper end of the base 100 is provided with mounting grooves 110 that are arranged equidistantly from the front end to the rear end thereof. The escalator assembly includes a step plate 200 horizontally arranged at the opening position of each mounting groove 110, and a lifting stud 300 is connected to the lower end of the step plate 200. A screw sleeve 400 that is threadably matched with each lifting stud 300 is rotatably provided in the base 100, and each screw sleeve 400 is provided with a gear ring 500. The number of teeth of each gear ring 500 arranged from the front end to the rear end of the base 100 is arranged in a proportional decreasing manner. A horizontally arranged control rod 600 is provided in the base 100, and a worm end meshing with each gear ring 500 is provided on the control rod 600. The rotation of the control rod 600 drives each lifting stud 300 to rotate at different speed differences to raise each step plate 200.

[0026] like Figures 1 to 3 As shown, through the above arrangement, the escalator device in this embodiment is convenient for patients to make adaptive adjustments at different rehabilitation stages by arranging a height-adjustable step plate 200 structure on the base 100; each step plate 200 of the step assembly is arranged at the opening of the mounting groove 110, and when each step plate 200 is not raised, the upper end of the base 100 as a whole forms a planar structure, which can be used as a walking training structure; the lower end of the step plate 200 is connected to the oil lifting stud 300, and during adjustment, each lifting stud 300 is rotated at different speeds to make the step plate 200 rise to different heights within a corresponding time to achieve adjustment, and the screw sleeve 400 matched with the lifting stud 300 cooperates with the control rod 600 through the gear ring 500. Since the number of teeth of each gear ring 500 is arranged in proportional decreasing order, the control rod When 600 rotates, the rotation speed of each lifting stud 300 from the front end to the rear end of the base 100 gradually increases. In equal time, the height of each step plate 200 increases step by step along the front end to the rear end of the base 100. Therefore, during adjustment, the step plate 200 can be raised to different heights through different rotation times, thereby forming a training step structure with different step heights. It has a variety of training trajectories. When in use, the height of each step can be adjusted according to the patient's physical improvement, so that the patient can participate in up and down stair training as early as possible. It has strong flexibility in use. The step plates 200 provided in this embodiment are four groups. In actual use, the rotation speed ratio of the lifting stud 300 connected to the step plates 200 is 1:2:3:4; thereby, the step plates 200 can be raised to different heights in equal time to form a step structure.

[0027] like Figures 1 to 3As shown, in this embodiment, the step plate 200 at the rear end of the base 100 is further hinged with a ramp plate 700, and the bottom surface of the ramp plate 700 is slidably matched with the sliding platform 120 provided at the rear end of the base 100. The ramp plate 700 is used for patients to perform slope walking training in an inclined state, and to improve the rehabilitation training effect. In order to improve the stability of walking training, anti-slip plates 1700 are arranged at intervals on the upper end surface of the ramp plate 700, and ramp handrails 1800 are provided on both sides of the long edge of the ramp plate 700. The anti-slip plate 1700 can play an anti-slip role in increasing friction, and the ramp handrails 1800 are used to provide hand support to ensure the safety of patients in slope walking training.

[0028] like Figures 1 to 3 As shown, in order to improve the stability of the step plate 200 when it rises to different heights, the present embodiment is provided with a fork-scissor type lifting frame 800 in the mounting groove 110, and the upper and lower ends of the fork-scissor type lifting frame 800 are respectively fixedly connected to the lower end of the step plate 200 and the bottom wall of the mounting groove 110. The fork-scissor type lifting frame 800 can be unfolded or folded accordingly as the step plate 200 rises and falls, and can play a role in supporting the step plate 200, thereby improving the stability of the step plate 200 at different heights.

[0029] Embodiment 2

[0030] like Figures 1 to 3As shown, when patients are initially trained to walk up and down the escalator structure, a handrail structure is usually needed to improve the safety of the walking process. The present embodiment provides a handrail structure, specifically, a retractable handrail rod 900 is provided on both sides of the upper end of the base 100, and handrail columns 1000 are hinged at both ends of the handrail rod 900, and the lower ends of the handrail columns 1000 are connected to the step plates 200 at the front and rear ends of the base 100. Since both ends of the handrail bar 900 are installed on the step plate 200 through the handrail columns 1000, when the step plate 200 is at different heights during the lifting process, the handrail bar 900 can adaptively retract and extend and be in an inclined state as the step plate 200 rises, which is convenient for patients to provide handholds when going up and down the stairs, thereby improving training safety; this embodiment also has a gripping cover 1100 on the handrail bar 900, and the inner wall of the gripping cover 1100 is provided with symmetrically arranged friction blocks 1200, and the outer side of the friction block 1200 passes through the outer wall of the gripping cover 1100 to form a gripping portion 1210, and the inner wall of the gripping cover 1100 is provided with a spring 1300 connected to the friction block 1200, and pressing the gripping portion 1210 can make the friction block 1200 contact with the outer peripheral surface of the handrail bar 900. In this way, when the user needs handrail support during walking up and down, he can hold the gripping sleeve 1100 on the corresponding side with both hands. During the walking process, the gripping sleeve 1100 can slide along the handrail bar 900 to the corresponding position, and when the user presses the gripping portion 1210, the friction block 1200 can be in surface contact with the handrail bar 900 to achieve positioning. The gripping sleeve 1100 no longer slides, which is convenient for the user to stop at any time during walking and provide good support for the hand position. In order to improve the stability of the contact and positioning of the friction block 1200 with the handrail bar 900, the present embodiment also provides a positioning groove 910 arranged along the length of the handrail bar 900 and slidingly adapted to the friction block 1200, and the bottom wall of the positioning groove 910 is provided with a friction belt 920. Pressing the gripping portion 1210 can make the friction block 1200 in surface contact with the friction belt 920. When the patient presses the gripping portion 1210 during use, the friction block 1200 can be inserted into the positioning groove 910 and contact the surface of the friction belt 920, which can increase the static friction and improve the stability of the gripping sleeve 1100 during positioning.

[0031] like Figures 1 to 3 As shown, when the device is in use, when the step plates 200 rise to different heights, there are open gaps between adjacent step plates 200. At this time, the openings need to be closed to prevent the patient from tripping during walking training. In this embodiment, elastic expansion sheets 1400 are connected between adjacent step plates 200. The expansion sheets 1400 close the open gaps between adjacent step plates 200 when the step plates 200 rise, preventing the patient from tripping over the edge of the step plates 200.

[0032] like Figures 1 to 3As shown, the screw sleeve 400 located in the installation groove 110 needs to be installed in a rotatable manner so that the screw sleeve 400 can drive the step plate 200 to rise or fall when it is rotated. In this embodiment, a connecting tube 1500 is provided at the bottom of each installation groove 110 of the base 100, and a thrust bearing 1600 is provided at the upper end of the connecting tube 1500 to abut against the screw sleeve 400. In this way, the thrust bearing 1600 can be installed in a rotatable manner on the screw sleeve 400, and the screw sleeve 400 rotates so that the lifting stud 300 can penetrate into the connecting tube 1500 to be folded when it descends.

[0033] In this embodiment, a U-shaped guardrail is provided on the upper end of the step plate 200 located at the rear end of the base 100, and the guardrail surrounds both sides of the step and is arranged near the rear end of the base 100. The guardrail can play the role of surrounding the step plate 200 to ensure the safety of the patient when walking to the highest position.

[0034] like Figures 1 to 3 As shown, in actual application, in order to realize the automation of height adjustment of the step plate 200, the present embodiment is provided with a motor module 1900 in the base 100, the output end of the motor module 1900 is connected to the control rod 600 through the reducer assembly, the motor module 1900 is connected to the control module by signal, and the control module is connected to the handheld controller assembly. In this way, the motor module 1900 can be controlled by the handheld controller assembly, and the motor module 1900 drives the control rod 600 to rotate forward or reverse, and the height adjustment of the step plate 200 is automatically completed. In order to facilitate the transfer of equipment and improve the stability of the equipment during use, a self-locking universal wheel set is provided at the bottom of the front and rear ends of the base 100, and a support column is also provided on both sides of the base 100 to rotate, and the support column can be rotated downward to a vertical position to support the base 100, and a pad is screwed at the lower end of the support column. In this way, when the equipment needs to be transferred, the equipment can be transferred through the universal wheel set. After the universal wheel set is self-locked, the support column can be rotated downward to a vertical position, and the pad block can be used to form a stable support for the base 100, thereby improving the stability of the equipment and avoiding shaking during walking training.
