Description

Technical Field

[0001] The utility model relates to the technical field of rehabilitation training, in particular to a limb rehabilitation training assisting robot. Background Art

[0002] There are many different types of equipment for limb rehabilitation, including treadmills, bicycles, elliptical machines, and various strength training equipment. When using aerobic equipment such as treadmills and bicycles for rehabilitation, the lower limbs are mainly exercised, while the upper limbs just follow the movement, and the upper limbs do not receive the same resistance training effect. Strength training equipment tends to be more isolated training, suitable for people training for muscle hypertrophy. It lacks specificity for the rehabilitation training group and cannot provide a coordinated training method for the upper and lower limbs.

[0003] Rehabilitation training is more inclined towards the functional recovery of limbs and the coordination of various joints, that is, the most basic movement of "stretching arms and legs". For this purpose, a limb rehabilitation training auxiliary robot is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a limb rehabilitation exercise assisting robot in order to solve the above problems, as described below.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

A sliding sleeve is slidingly provided on the surface of the guide rod, and a spring pin is passed through the sliding sleeve. A card hole is opened on the guide rod, and the card hole is adapted to the card pin of the spring pin. A metal spring is fixed on the sliding sleeve for supporting the connecting plate.

[0013] Preferably, the guide rod is rectangular.

[0014] Preferably, the pulling assembly includes a pull rod, two rotating shafts are rotatably provided at the top and bottom of the mounting frame, two wire pulleys are provided on the rotating shafts, two pull ropes are fixed to the bottom of the connecting plate, and the other ends of the pull ropes pass through the four wire pulleys and the top of the mounting frame in sequence and are fixed to the pull rod.

[0015] Preferably, the pull rod is of three sections, with a cross bar in the middle and downwardly inclined handles at both ends of the cross bar.

[0016] Preferably, an anti-slip strip is provided on the upper side of the pedal.

[0017] Preferably, a spring is sleeved on the surface of the slide rod, and two ends of the spring are respectively fixed to the pedal and the mounting bracket.

[0018] The beneficial effects are:

[0019] 1. The resistance adjustment mechanism adjusts the downward resistance of the pedals, and the legs reciprocate to step on the pedals to exercise the lower limbs. The upper limbs of the patient can be exercised by pulling the connecting plate downward through the pulling component. The upper and lower limbs can move simultaneously, achieving coordinated force between the upper and lower limbs of the patient and multi-joint connection, thereby accelerating the patient's recovery speed.

[0020] 2. By adjusting the downward resistance of the connecting plate through the resistance adjustment mechanism, the intensity of the rehabilitation training can be adjusted to achieve adaptation for different groups of people. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the embodiments described are only some of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0029] See also Figure 1-Figure 4 As shown, the utility model provides a limb rehabilitation exercise assisting robot, including a mounting frame 1, a seat 2 is provided on the mounting frame 1, two slide bars 3 are vertically slidably provided at the bottom of the mounting frame 1, a pedal 5 is fixed between the two slide bars 3, the lower ends of the slide bars 3 pass through the bottom of the mounting frame 1, and a connecting plate 6 is fixed between the lower ends of the two slide bars 3;

[0030] The mounting frame 1 is provided with a pulling assembly 7 for the user to pull the connecting plate 6 downwards with the upper limbs;

[0031] The mounting frame 1 is provided with a resistance adjustment mechanism 12 for adjusting the resistance encountered by the connecting plate 6 when it moves downward.

[0032] As an optional embodiment, the mounting frame 1 is in a horizontal U-shape.

[0033] The resistance adjustment mechanism 12 includes a fixed rod 14, which is fixed to the mounting frame 1. The fixed rod 14 is provided with a plurality of mutually parallel guide rods 15. A sliding sleeve 16 is slidably provided on the surface of the guide rod 15. A spring pin 17 is penetrated by the sliding sleeve 16. A locking hole 18 is opened on the guide rod 15, and the locking hole 18 is adapted to the locking pin of the spring pin 17. A metal spring 13 is fixed to the sliding sleeve 16 for supporting the connecting plate 6.

[0034] Move the sliding sleeve 16. When the spring pin 17 is plugged into the card hole 18, the metal spring piece 13 corresponds to the bottom of the connecting plate 6. The spring pin 17 and the card hole 18 cooperate to fix the position of the sliding sleeve 16. The more metal spring pieces 13 corresponding to the bottom of the connecting plate 6, the greater the resistance of the connecting plate 6 to the downward movement. Removing the metal spring piece 13 from the bottom of the connecting plate 6 can reduce the downward resistance of the connecting plate 6.

[0035] The guide rod 15 is rectangular, which can prevent the sliding sleeve 16 from rotating on the guide rod 15.

[0036] The pulling assembly 7 includes a pull rod 11. Two rotating shafts 8 are rotatably provided at the top and bottom of the mounting frame 1. Two guide pulleys 9 are provided on the rotating shafts 8. Two pull ropes 10 are fixed to the bottom of the connecting plate 6. The other ends of the pull ropes 10 pass through the four guide pulleys 9 and the top of the mounting frame 1 in sequence and are fixed to the pull rod 11.

[0037] Pull the pull rod 11 downward, and the pull rod 11 cooperates with the guide wheel 9 through the pull rope 10 to pull the connecting plate 6 downward.

[0038] The pull rod 11 is a three-section type, with a horizontal bar in the middle and downward-inclined handles at both ends of the horizontal bar. This design can provide the rehabilitator with two gripping positions: the rehabilitator can hold the horizontal bar upright, and the inclined handle allows the rehabilitator to hold the bar wide and change the force direction of the wrist.

[0039] An anti-slip strip is provided on the upper side of the pedal 5 .

[0040] A spring 4 is sleeved on the surface of the slide bar 3 , and both ends of the spring 4 are fixed to the pedal 5 and the mounting bracket 1 respectively. The spring 4 is used to push the pedal 5 upward.

[0041] With the above structure, the patient sits on the seat 2 and steps on the pedals 5 back and forth with both legs to exercise the lower limbs. The patient's upper limbs are exercised by pulling the connecting plate 6 back and forth downwards through the pulling assembly 7. The upper and lower limbs can be exercised simultaneously.
