Description

Technical Field

[0001] The utility model relates to a height-adjustable walker, in particular to a height-adjustable walker, and belongs to the technical field of rehabilitation equipment. Background Art

[0002] A walker is a tool that assists people in standing and walking, and is commonly used by the elderly and disabled. In clinical practice, walkers can also be used by patients who have undergone surgery and have lost the ability to walk, even after surgery. To achieve rapid recovery, early rehabilitation exercises should be performed after the condition stabilizes, allowing patients to get out of bed and move around as soon as possible. However, patients are unstable when getting out of bed, and using a walker can increase the contact area between the body and the ground when standing. When the center of gravity is at a certain position, the larger the contact area, the more stable the body. Therefore, a walker can replace the patient's weight support, making it easier for patients to perform walking exercises. However, most existing walkers only focus on solving the problem of walking assistance. Their single function cannot be well targeted at patients with other usage needs. For example, patients who have undergone cardiac surgery need to use ECG monitoring equipment at any time when getting out of bed and need to sit down to rest when tired. Existing walkers are not convenient for placing medical equipment such as ECG monitors, do not have the function of supporting patients to sit down and rest, and cannot assist patients in doing other leg exercises, such as cycling, which can promote blood circulation in patients and prevent complications such as thrombosis. Therefore, existing walkers cannot well meet the usage needs of patients.

[0003] A patented walker, patent number CN216496416U, includes two spaced-apart brackets, a footrest, and a seat assembly. A heart monitor holder is connected between the front ends of the two brackets. The footrest is connected between the two brackets and located at the lower front ends. The seat assembly is connected between the two brackets and located at the upper-middle rear ends. This walker can accommodate medical equipment such as a heart monitor while assisting patients in walking, and can provide a place for patients to sit and rest when fatigued.

[0004] However, the armrest in patent authorization number CN216496416U is a fixed structure and cannot be adjusted. Since the walker is used by people of different heights, a walker that can be suitable for people of different heights is needed. To this end, we propose a height-adjustable walker. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a height-adjustable walker.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

The end portion of the upper surface of the base is fixedly connected to a guide post via a bracket. A sliding sleeve is symmetrically slidably connected to the outer side of the guide post. The top of the sliding sleeve is fixedly connected to a first connecting shaft.

[0008] A connecting seat is installed above the guide column, a second connecting shaft is symmetrically fixedly connected to the bottom of the connecting seat, an armrest is connected to the top of the connecting seat via a support rod, and both ends of the armrest are covered with anti-slip rubber sleeves;

[0009] One side of the guide column is rotatably connected to a lead screw, and the lead screw is screwed to the connecting seat;

[0010] A support arm is installed between the first connecting shaft and the second connecting shaft, and two ends of the support arm are rotatably connected to the first connecting shaft and the second connecting shaft respectively.

[0011] Preferably, columns are symmetrically fixedly connected to the upper surface of the base, and connecting rods are fixedly connected to the top ends of the columns.

[0012] Preferably, a nylon belt is connected to the connecting rod, and a plurality of nylon belts are equidistantly arranged at axial positions of the connecting rod.

[0013] Preferably, a seat cushion is sewn and connected between the symmetrically arranged nylon belts.

[0014] Preferably, a hand wheel is installed at the top end of the lead screw, and an anti-slip protrusion is integrally formed on the edge of the hand wheel.

[0015] Preferably, both ends of the support arm are provided with axial holes, and the inner diameters of the axial holes are respectively adapted to the outer diameters of the first connecting shaft and the second connecting shaft.

[0016] The height-adjustable walker proposed in this utility model has the following beneficial effects:

[0017] 1. The operator stands on the inner side of the base and drives the lead screw to rotate, so that the two ends of the support arm respectively cooperate with the first connecting shaft and the second connecting shaft to rotate, so that the sliding sleeve cooperates with the guide column to slide, and then the distance between the sliding sleeves can be adjusted. Therefore, the height of the handrail can be adjusted according to the height of the operator's hand holding the handrail, and the friction between the hand and the handrail can be increased by the anti-slip rubber sleeve. By adjusting the height of the handrail, the applicability of the walker can be improved.

An armrest 11 is connected to the top of the connecting seat 6 through a support rod, and both ends of the armrest 11 are covered with anti-slip rubber sleeves 12;

[0027] One side of the guide column 4 is rotatably connected to a lead screw 10, and the lead screw 10 is screwed to the connecting seat 6;

[0028] A support arm 7 is installed between the first connecting shaft 8 and the second connecting shaft 9, and both ends of the support arm 7 are rotatably connected to the first connecting shaft 8 and the second connecting shaft 9 respectively;

[0029] It should be noted that when using the height-adjustable walker, the operator stands on the inner side of the base 1 and drives the screw 10 to rotate, so that the two ends of the support arm 7 respectively cooperate with the first connecting shaft 8 and the second connecting shaft 9 to rotate, so that the sliding sleeve 5 cooperates with the guide column 4 to slide, and then the distance between the sliding sleeves 5 can be adjusted. Therefore, the height of the handrail 11 can be adjusted according to the height of the operator's hand holding the handrail 11, and the friction between the hand and the handrail 11 can be increased by the anti-slip rubber sleeve 12. By adjusting the height of the handrail 11, the applicability of the walker can be improved.

[0034] like Figure 3 、 Figure 4 As shown, both ends of the support arm 7 are provided with shaft holes, and the inner diameters of the shaft holes are respectively adapted to the outer diameters of the first connecting shaft 8 and the second connecting shaft 9;

[0035] It should be noted that the stability of the support arm 7 during the adjustment process is ensured, thereby ensuring the adjustment stability of the support arm 7.

[0036] Working principle: When in use, the operator stands on the inner side of the base 1 and drives the lead screw 10 to rotate, so that the two ends of the support arm 7 respectively cooperate with the first connecting shaft 8 and the second connecting shaft 9 to rotate, so that the sliding sleeve 5 cooperates with the guide column 4 to slide, and then the distance between the sliding sleeves 5 can be adjusted. Therefore, the height of the armrest 11 can be adjusted according to the height of the operator's hand holding the armrest 11, and the friction between the hand and the armrest 11 can be increased by the anti-slip rubber sleeve 12, and the height of the armrest 11 can be adjusted.
