Description

Technical Field

[0001] The invention relates to the technical field of leg care devices, and in particular to a leg care device which is easy to adjust. Background Art

[0002] In the field of leg rehabilitation for the elderly, the elderly's legs need to be regularly rehabilitated and cared for. However, when medical staff massage and exercise the legs of elderly patients for rehabilitation, it is not only time-consuming and laborious but also prone to fatigue. Therefore, it is necessary to design a device that can replace manpower to perform exercise and care for the legs of elderly patients.

[0003] Most of the existing leg care devices lack a relay transmission component that can extend the driving distance between the component that brakes the flywheel and the seat. As a result, when a person is sitting on the seat and pedaling the flywheel to perform rehabilitation exercise, when both hands are far away from the brake component, the brake torque of the brake component cannot be directly adjusted. The person needs to stand up, stop exercising, and move to a position close to the brake component before he can reach out and tighten the brake component to adjust the brake torque. This is troublesome and inconvenient to operate, which reduces the overall practicality of the care device. It is especially not suitable for use by elderly people with limited mobility, affecting the use effect and wide application of the care device. Summary of the invention

[0004] In view of this, the present invention provides an easily adjustable leg care device to solve the problem that the person needs to stand up and stop exercising, move to a position close to the brake component, and then reach out to hold the loose brake component to adjust the brake torque, which is troublesome and inconvenient to operate.

[0005] The technical solution proposed by the present invention is: an adjustable leg care device, specifically comprising: a base, a cross bracket is welded inside the base, two vertical support rods are symmetrically welded in the middle position of the longitudinal support rod of the cross bracket, and a flywheel is rotatably installed between the top ends of the two vertical support rods;

[0006] An arc-shaped brake plate is installed below the flywheel, and two square slip rings are symmetrically welded on both sides of the arc-shaped brake plate. The two square slip rings are correspondingly slidably matched with two vertical support rods, and a nylon brake pad is fixed on the top of the arc-shaped brake plate, and the nylon brake pad is in extrusion and friction contact with the flywheel; a wedge-shaped driving block is welded at the bottom of the arc-shaped brake plate;

[0007] The tail end of the cross support cross brace is fixedly installed with a vertical support, and a bench is fixed on the top of the vertical support; the top of the cross support cross brace is slidably installed with a relay drive assembly; the relay drive assembly is composed of a longitudinal support slide, a rectangular force transmission frame welded to the tail end of the longitudinal support slide, and an L-shaped positioning plate welded to the tail end of the rectangular force transmission frame, wherein a wedge-shaped driving block is welded to the head end of the longitudinal support slide, and the L-shaped positioning plate is penetrated and slidably matched with the bottom part of the vertical support;

[0008] The inclined surface of the wedge-shaped driving block is in contact with the inclined surface of the triangular force-bearing block; a relay driving ring is slidably installed on the top part of the vertical support column, and a connecting rod is rotatably connected between the relay driving ring and the tail end of the L-shaped positioning plate.

[0009] Furthermore, two positioning square sleeves are welded at intervals on a portion of the top end of the cross support cross brace bar that deviates from the middle, and the longitudinal support slide plate is slidably matched with the two positioning square sleeves.

[0010] Furthermore, the rotating shaft of the flywheel is rotatably fitted through the top end portions of the two vertical support rods, and two cranks supporting each other are welded at both ends of the rotating shaft, and pedals are rotatably mounted on the head end portions of the cranks.

[0011] Furthermore, the middle section of the vertical pillar is welded with a limit ring, and the part of the vertical pillar located above the relay drive ring is slidably mounted with a drive ring; the part of the vertical pillar located above the limit ring is symmetrically mounted with two springs, and the head ends of the two springs are in contact with the relay drive ring, and the tail ends are in contact with the limit ring and the drive ring respectively.

[0012] Furthermore, a longitudinally supported U-shaped mounting frame is welded to the circumferential outer ring of the driving ring, and a longitudinal support shaft is slidably installed inside the U-shaped mounting frame through a spring push; a row of vertically arranged positioning holes is provided at the top end portion of the vertical support pillar, and the head end portion of the longitudinal support shaft passes through the driving ring and is plugged into and matched with a row of positioning holes in an optional manner.

[0013] Furthermore, a hexagonal vertical shaft is welded to another part of the top end of the cross support cross brace that deviates from the middle, and an auxiliary care component is installed on the hexagonal vertical shaft.

[0014] Furthermore, the auxiliary care component is composed of a longitudinally arranged U-shaped sliding frame and a massage roller rotatably installed in the top opening of the U-shaped sliding frame. The massage roller is longitudinally supported and has multiple rows of massage balls arranged around the outer circumference.

[0015] Furthermore, the middle section of the bottom side rod of the U-shaped sliding frame is slidably matched with the hexagonal vertical shaft through spring pushing; when the two feet step on the driving flywheel through the two pedals, the two thighs are alternately pressed against the massage roller.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The drive ring is located below the bench, close to the hands of the person sitting on the bench, so that the person can drive it manually directly. This allows the person who sits on the bench and steps on the drive flywheel to perform exercise and rehabilitation, to directly drive the drive ring manually to adjust the brake torque of the flywheel in a sitting exercise posture. Compared with the existing technology that lacks a relay drive component, it saves the trouble of the person getting up to pause the exercise and moving to a position close to the arc brake plate before reaching out to hold the arc brake plate to adjust the brake torque. The operation is convenient and efficient, which helps to improve the overall practicality of the nursing device, and can be better suitable for use by elderly people with limited mobility, which is conducive to improving the use effect and wide application of the nursing device.

[0018] 2. When the drive ring slides down and pushes the relay drive ring to adjust the brake load of the flywheel, it may happen that when the arc-shaped brake plate and the nylon brake pad have been tightly pressed and contacted with the flywheel, the longitudinal support shaft has not slid to the positioning hole of the corresponding height and cannot be normally plugged into the positioning hole. In this case, since the arc-shaped brake plate and the nylon brake pad have been pressed against the limit by the flywheel, the relay drive ring will also be statically limited. At this time, when the relay drive ring is statically limited, the drive ring can compress the spring on the upper side of the vertical support column to continue to drive the longitudinal support shaft to slide down, drive the longitudinal support shaft to slide down to the positioning hole, and normally plug and cooperate with the positioning hole. Compared with the traditional care device that is not equipped with a drive ring and the upper side spring on the vertical column, but directly sets the longitudinal support shaft on the relay drive ring, it helps to ensure the normal and effective implementation of the longitudinal support shaft plug-in positioning function.

[0019] 3. The massage roller can implement rolling massage care for the thighs of exercise and rehabilitation personnel through the multiple rows of massage balls arranged around it. Rolling massage of the thighs can promote blood circulation in the legs, relieve muscle tension and fatigue, and help rehabilitation personnel relax and relieve stress. The setting of the massage roller enables the nursing device to have a thigh massage function, which helps to enrich the functions of the nursing device, further enhance the practicality of the device, and also makes the device compatible with more forms of massage needs, which is conducive to further improving the use effect of the device.

[0039] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of the present invention.

[0040] Please refer to Figures 1 to 8 ;

[0041] Embodiment 1:

[0042] The present invention proposes an adjustable leg care device, comprising: a base 1, a cross bracket welded inside the base 1, two vertical support rods 101 symmetrically welded in the middle position of the longitudinal support rod of the cross bracket, and a flywheel 3 rotatably installed between the top ends of the two vertical support rods 101.

[0043] An arc-shaped brake plate 6 is installed below the flywheel 3, and two square slip rings 602 are symmetrically welded on both sides of the arc-shaped brake plate 6. The two square slip rings 602 correspond to the two vertical support rods 101 for sliding cooperation, and a nylon brake pad 601 is fixed on the top of the arc-shaped brake plate 6, and the nylon brake pad 601 is in extrusion and friction contact with the flywheel 3; a wedge-shaped drive block 501 is welded at the bottom of the arc-shaped brake plate 6.

[0044] Through the nylon brake pad 601, the arc-shaped brake plate 6 can implement extrusion friction braking on the flywheel 3, increase the load of the flywheel 3 and the driving force required for the person to pedal to drive the flywheel 3, thereby achieving the purpose of exercising the legs of the rehabilitation personnel, and sliding the arc-shaped brake plate 6 up and down can adjust the braking torque applied to the flywheel 3, increase or decrease the load of the flywheel 3, meet the usage requirements of different groups of people with different exercise intensities, and enhance the wide application of the nursing device.

[0045] The tail end of the cross support cross brace is fixedly installed with the vertical pillar 2, and the top of the vertical pillar 2 is fixed with a bench 7; the top of the cross support cross brace is slidably installed with the relay drive assembly 5; the relay drive assembly 5 is composed of a longitudinal support slide, a rectangular force transmission frame welded to the tail end of the longitudinal support slide, and an L-shaped positioning plate 502 welded to the tail end of the rectangular force transmission frame, wherein the head end of the longitudinal support slide is welded with a wedge-shaped drive block 501, and the L-shaped positioning plate 502 is slidably matched with the bottom side of the vertical pillar 2; the inclined surface of the wedge-shaped drive block 501 is in contact with the inclined surface of the triangular force block 603; the top part of the vertical pillar 2 is slidably installed with the relay drive ring 202, and the relay drive ring 202 is rotatably connected to the tail end of the L-shaped positioning plate 502.

[0046] Through the inclined guiding principle of the wedge-shaped driving block 501 and the triangular force-bearing block 603 and in conjunction with the gravity of the arc-shaped brake plate 6 itself, the reciprocating sliding relay driving assembly 5 can push the arc-shaped brake plate 6 and the nylon brake pad 601 to slide up and down; the L-shaped positioning plate 502, the connecting rod 503 and the relay driving ring 202 are connected together to form a crank slider mechanism, through which the up and down sliding relay driving ring 202 can drive the relay driving assembly 5 to slide back and forth.

[0047] Two positioning square sleeves 103 are welded at intervals on a portion of the top end of the cross support cross brace that deviates from the middle, and the longitudinal support slide plate penetrates and slides with the two positioning square sleeves 103 .

[0048] The rotating shaft of the flywheel 3 is rotatably matched with the top ends of the two vertical support rods 101, and two cranks 301 supporting each other are welded at both ends of the rotating shaft, and a pedal 302 is rotatably mounted on the head end of the crank 301.

[0049] The middle section of the vertical support 2 is welded with a limit ring 201, and the part of the vertical support 2 located above the relay drive ring 202 is slidably mounted with a drive ring 203; the part of the vertical support 2 located above the limit ring 201 is symmetrically mounted with two springs, the head ends of the two springs are in contact with the relay drive ring 202, and the tail ends are in contact with the limit ring 201 and the drive ring 203 respectively.

[0050] Through the power transmission of the spring on the upper side of the vertical pillar 2, the drive ring 203 can push down the relay drive ring 202, and when the relay drive ring 202 is driven to slide down, the springs on the upper and lower sides of the vertical pillar 2 are compressed. When the drive ring 203 is released, the spring automatically rebounds and pushes the relay drive ring 202 to slide up and reset; then through the power transmission of the relay drive assembly 5 and used together with the springs on the upper and lower sides of the vertical pillar 2, the up and down sliding drive ring 203 can push and drive the arc brake plate 6 and the nylon brake pad 601 to slide up and down, so as to adjust the braking torque of the flywheel 3, and the drive ring 203 is located below the stool 7, close to the hands of the person sitting on the stool 7. The part can be conveniently driven manually by personnel, so that the personnel who sit on the bench 7 and pedal the flywheel 3 to perform exercise and rehabilitation can directly manually drive the drive ring 203 to adjust the braking torque of the flywheel 3 in a sitting exercise posture. Compared with the existing technology that lacks a relay drive component 5, it saves the trouble of personnel getting up to pause exercise and moving to a position close to the arc-shaped brake plate 6 before reaching out to hold the arc-shaped brake plate 6 to adjust the braking torque. The operation is convenient and efficient, which helps to improve the overall practicality of the nursing device, and can be better suitable for use by elderly people with limited mobility, which is conducive to improving the use effect and wide application of the nursing device.

[0051] A longitudinally supported U-shaped mounting frame 2031 is welded to the circumferential outer ring of the driving ring 203, and a longitudinal support plug shaft 2032 is slidably installed inside the U-shaped mounting frame 2031 through the pushing of a spring; a row of vertically arranged positioning holes is provided at the top portion of the vertical pillar 2, and the head end portion of the longitudinal support plug shaft 2032 passes through the driving ring 203 and is plugged into and matched with a row of positioning holes in an optional form.

[0052] The longitudinal support shaft 2032 is plugged into a row of positioning holes to insert and position the drive ring 203, fix the arc brake plate 6 at the use height after sliding adjustment, and implement extrusion friction braking on the flywheel 3 with the adjusted braking torque.

[0053] When the drive ring 203 slides down to push the relay drive ring 202 to adjust the brake load of the flywheel 3, it may happen that when the arc brake plate 6 and the nylon brake pad 601 are in close contact with the flywheel 3, the longitudinal support shaft 2032 has not slid to the positioning hole at the corresponding height and cannot be normally plugged into the positioning hole. In this case, since the arc brake plate 6 and the nylon brake pad 601 have been pressed against the limit by the flywheel 3, the relay drive ring 202 will also be statically limited. After the relay drive ring 202 is stationary and limited, the drive ring 203 can compress the spring on the upper side of the vertical pillar 2 to continue to drive the longitudinal support shaft 2032 to slide down, drive the longitudinal support shaft 2032 down to the positioning hole, and normally engage with the positioning hole. Compared with the traditional nursing device that is not equipped with a drive ring 203 and the upper spring on the vertical pillar 2, but directly sets the longitudinal support shaft 2032 on the relay drive ring 202, it helps to ensure the normal and effective implementation of the longitudinal support shaft 2032 plug-in positioning function.

[0054] When the driving ring 203 is driven up and down, the longitudinal support shaft 2032 needs to be pulled out from the positioning hole first to loosen the driving ring 203; the longitudinal support shaft 2032 is used for being held by hand to drive the driving ring 203 up and down.

[0055] Based on the first embodiment, the second embodiment:

[0056] A hexagonal vertical shaft 102 is welded to another part of the cross bracket's cross brace, which is away from the middle. An auxiliary care component 4 is installed on the hexagonal vertical shaft 102. The auxiliary care component 4 is composed of a longitudinally arranged U-shaped sliding frame 402 and a massage roller 401 rotatably installed in the top opening of the U-shaped sliding frame 402. The massage roller 401 is longitudinally supported, and multiple rows of massage balls are arranged around the outer circumference.

[0057] The middle section of the bottom side rod of the U-shaped sliding frame 402 is slidably matched with the hexagonal vertical shaft 102 through the spring push; when the two feet step on the driving flywheel 3 through the two pedals 302, the two thighs are alternately pressed against the massage roller 401.

[0058] The massage roller 401 can implement rolling massage care for the thighs of the exercise and rehabilitation personnel through the multiple rows of massage balls arranged around it. Rolling massage of the thighs can promote blood circulation in the legs, relieve muscle tension and fatigue, and help the rehabilitation personnel relax and relieve stress. The setting of the massage roller 401 enables the care device to have a thigh massage function, which helps to enrich the functions of the care device, further enhance the practicality of the device, and also makes the device compatible with more forms of massage needs, which is conducive to further improving the use effect of the device.

[0059] When the two thighs press against the massage roller 401 alternately, they will follow the pedaling action of the two feet and slide back and forth toward or away from the flywheel 3. When the two thighs slide back and forth, the friction will drive the massage roller 401 to rotate forward and reverse, realizing rolling massage on it; the spring on the hexagonal vertical shaft 102 can provide buffer protection for the two thighs.

[0060] The working principle of this embodiment is as follows: when in use, a person who needs rehabilitation exercise sits on the bench 7 and steps his feet on two pedals 302 respectively. After completing the above initial use steps, the feet can pedal to drive the flywheel 3 to rotate and start rehabilitation exercise for the legs.

[0061] Through the nylon brake pad 601, the arc-shaped brake plate 6 can implement extrusion friction braking on the flywheel 3, increase the load of the flywheel 3 and the driving force required for the person to pedal to drive the flywheel 3, thereby achieving the purpose of exercising the legs of the rehabilitation personnel, and sliding the arc-shaped brake plate 6 up and down can adjust the braking torque applied to the flywheel 3, increase or decrease the load of the flywheel 3, and meet the usage requirements of different people with different exercise intensities.

[0062] Through the inclined guiding principle of the wedge-shaped driving block 501 and the triangular force-bearing block 603 and in conjunction with the gravity of the arc-shaped brake plate 6 itself, the reciprocating sliding relay driving assembly 5 can push the arc-shaped brake plate 6 and the nylon brake pad 601 to slide up and down; the L-shaped positioning plate 502, the connecting rod 503 and the relay driving ring 202 are connected together to form a crank slider mechanism, through which the up and down sliding relay driving ring 202 can drive the relay driving assembly 5 to slide back and forth.

[0063] Through the power transmission of the spring on the upper side of the vertical support 2, the drive ring 203 can push down the relay drive ring 202, and when the relay drive ring 202 is driven to slide down, it compresses the springs on the upper and lower sides of the vertical support 2. When the drive ring 203 is released, the spring automatically rebounds and pushes the relay drive ring 202 to slide up and reset; then, through the power transmission of the relay drive assembly 5 and in conjunction with the springs on the upper and lower sides of the vertical support 2, the up and down sliding drive ring 203 can push and drive the arc brake plate 6 and the nylon brake pad 601 Slide up and down to adjust the braking torque of the flywheel 3; the longitudinal support shaft 2032 is plugged into a row of positioning holes to position the drive ring 203, fix the arc-shaped brake plate 6 at the use height after sliding adjustment, and use the adjusted braking torque to squeeze and friction brake the flywheel 3; when driving the drive ring 203 up and down, it is necessary to first separate the longitudinal support shaft 2032 from the positioning hole and loosen the drive ring 203; the longitudinal support shaft 2032 is used for holding by hand to drive the drive ring 203 up and down.

[0064] The massage roller 401 can provide rolling massage care for the thighs of the exercise and rehabilitation personnel through the multiple rows of massage balls arranged around it. When the two thighs are alternately pressed against the massage roller 401, they will follow the pedaling action of the two feet and slide back and forth toward or away from the flywheel 3. When the two thighs slide back and forth, the friction will drive the massage roller 401 to rotate forward and reverse, thereby realizing rolling massage for it; the spring on the hexagonal vertical shaft 102 can provide buffering protection for the two thighs.
