Description

Technical Field

[0001] The present invention relates to the technical field of big health exercise equipment, and specifically to a leg flexion and extension device based on the big health field and a method of using the device. Background Art

[0002] With the rapid development of life, many people are busy with work and ignore health issues. They even rest at home during their rest time. When they rest at home, they tend to stay in bed all day or play with their mobile phones, thus rarely doing physical exercise. However, the existing leg exercise equipment has a single function and cannot combine work and rest. Long-term exercise will become boring and occupy indoor space. Summary of the invention

[0003] The purpose of the present invention is to provide a leg flexion and extension device based on the field of general health and a method of use thereof to solve the problems raised in the above-mentioned background technology.

[0004] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a leg flexion and extension device based on the field of big health, comprising two pads, a large gear is commonly installed between the rear parts of the two pads, and a pedal is installed on the top of the large gear, back support plates are movably installed inside both sides of the pads, telescopic rods are movably installed on the top two side surfaces of the large gear, and the movable part of the telescopic rod is connected to the back support plate through a rotating shaft, a slider is commonly installed between the two pads, and a pillow is installed at the top middle position of the slider, an adjusting disk is installed on the front end surface of the pad, and one end of the adjusting disk is used in conjunction with the slider.

[0005] Preferably, small gears are installed inside the pads on both sides of the large gear, and a cam is fixedly installed on the top of the small gear, a fan blade is fixedly installed on the top of the cam, a piston tube is installed inside the pad, and the movable part of the piston tube is located on the rotation path of the cam.

[0006] Preferably, a leg placement platform is installed on the top of the pad, and a soft rubber pad is installed on the front end surface of the leg placement platform. A spring pull-out plate is movably installed at the rear of the leg placement platform, and the bottom of the spring pull-out plate is connected to the output part of the piston tube through a hose.

[0007] Preferably, a push rod is installed inside the leg placement platform through a through hole, one end of the push rod is connected to the top of the cam, and the other end of the push rod is used in conjunction with a soft rubber pad.

[0008] Preferably, a massage component is provided on the surface of the pillow, and the massage component is located at the edge of the surface of the pillow.

[0009] Preferably, a limiting slide groove plate is installed on the surface of the sliding block, a spring is installed inside the limiting slide groove plate, a wedge block is installed inside the limiting slide groove plate, and the top of the wedge block is connected to the bottom of the pillow pad through a connecting rod.

[0010] Preferably, a groove is provided on the surface of the sliding block, and an adjusting push plate is installed at the front end of the back support plate, and the adjusting push plate is located inside the groove and is used in conjunction with the wedge block.

[0011] A method for using a leg flexion and extension device based on the field of big health: Step 1: Leg exercise: The exerciser lies flat on the mat surface, lifts his legs and places his feet on the pedal surface, at this time, one leg is pushed forward and the other is curled up, repeating the operation to make the pedal swing back and forth, thereby exercising the legs; Step 2: Back massage: The movement of the telescopic rod drives the back support board to slide, which can perform rolling massage on the back of the exerciser; Step 3: Heat dissipation: The small gear will drive the cam and the fan blades to rotate, speeding up the air flow, which can dissipate heat from the calf of the exerciser, combining work and rest to reduce exercise fatigue; Step 4: Reduce fatigue: The layout of the spring pull-out plate can provide a certain support for the leg extension process to avoid fatigue caused by the legs hanging in the air for too long. Two interconnected grooves are set at the edge of the top surface of the spring pull-out plate to cool down the legs of the exerciser and improve the fun and comfort of the exercise process; Step 5: Thigh exercise: The push rod stretches and pushes out inside the leg placement table, which can lightly tap the surface of the thigh of the exerciser, thereby achieving a massage effect and also serving as an auxiliary exercise; Step 6: Neck massage: The movement of the wedge-shaped block can cause one side of the pillow to deform and move toward the neck or head skin of the exerciser to massage the neck or head of the exerciser.

[0012] Compared with the prior art, the present invention has the following beneficial effects: The present invention provides pedals, and the exerciser lies flat on the surface of the pad, lifts the legs and places the soles of the feet on the surface of the pedals, at which time one leg is pushed forward and the other is curled up, and the pedals are repeatedly operated to swing back and forth, thereby exercising the legs.

[0013] The present invention provides a back support plate, and the swing of the pedal drives the large gear to rotate back and forth. The reciprocating rotation of the large gear drives the pedals on the top two sides of the back support plate to swing. Since the back support plate limit movement is inside the pad, it is driven to reciprocate a certain distance with the swing of the telescopic rod, and the limit button on the surface of the telescopic rod can be adjusted according to the height difference of the exercisers. In addition, since a slider is movably installed inside the pad in front of the back support plate, a pillow pad is installed at the top middle position of the slider, which can be used together with an adjusting disk for people with different neck lengths to form a support for the neck and head of the exerciser. Therefore, the movement of the telescopic rod drives the back support plate to slide, which can perform rolling massage on the back of the exerciser, avoid tension in the back and accelerated fatigue during leg stretching, and enable the exerciser to exercise in a relaxed state, thereby increasing the exercise time.

[0014] The present invention sets a small gear, and the rotation of the large gear will also drive the two sets of meshing small gears to rotate. Since there are differences in diameter and teeth between the large gear and the small gear, the large gear can drive the small gear to rotate at a larger angle and faster speed. The small gear will drive the cam and the fan blades to rotate. The fan blades are common blowing parts in the prior art, and their rapid rotation can produce blowing. Rotating blowing is not performed here, and the air flow can be accelerated. By accelerating the air flow, the calf of the exerciser can be cooled, and the combination of work and rest can reduce the fatigue of exercise.

[0015] The present invention provides a spring draw-out plate. The leg placement platform and the spring draw-out plate are arranged so that the calf of the exerciser can be located on the surface of the spring draw-out plate, and the heel is located at the end edge of the spring draw-out plate. The spring draw-out plate can provide a supporting effect for the legs. A spring is provided at the connection position between the leg placement platform and the inner part of the spring draw-out plate. When the spring draw-out plate contracts, it provides a certain resistance, thereby increasing the intensity of exercise and facilitating the ejection and resetting of the spring draw-out plate. Therefore, the arrangement of the spring draw-out plate can provide a certain support for the leg extension process, thereby avoiding fatigue caused by the legs being suspended in the air for too long.

[0016] The present invention provides a piston tube, and the reciprocating swing of the cam can squeeze the movable part of the piston tube. The telescopic movement of the movable part of the piston tube can drive the movement of the internal piston. When the piston moves, air can be squeezed and blown, and the blown gas is connected to the spring pull-out plate through a hose. Two interconnecting grooves are provided at the edge of the top surface of the spring pull-out plate, so the air can be blown out from the interconnecting grooves and cool the legs of the exerciser, thereby improving the fun and comfort of the exercise process.

[0017] The present invention provides a soft rubber pad, and the rotation of the cam can drive the top rotatably connected push rod to move, that is, the push rod performs stretching and ejecting movements inside the leg placement platform. In addition, because one end of the push rod is connected to the soft rubber pad, the reciprocating movement of the push rod can drive the soft rubber pad to be ejected or contracted during exercise, thereby lightly tapping the surface of the thigh of the exerciser, thereby achieving a massage effect, and also playing a role in assisting exercise.

[0018] The present invention arranges a wedge-shaped block, and the movement of the back support plate can drive the synchronous movement of the adjusting push plate. Due to the inclined structure of the wedge-shaped block, the ejection of the adjusting push plate can squeeze the wedge-shaped block to move to one side. Since a limiting slide groove plate is installed on the surface of the slider, and a spring is installed inside the limiting slide groove plate, the wedge block makes a linear motion in the limiting slide groove plate. The movement of the wedge block can drive one side of the pillow pad to deform and tend to the neck or head skin of the exerciser. The foam or rubber material on the surface is arranged, and one side of the pillow pad reciprocates to deform, so as to massage the neck or head of the exerciser. The exerciser can exercise all the extra parts while reading or playing with the mobile phone, so as to improve the physical fitness by combining work and rest. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. Example 1

[0024] like Figure 1 As shown, this embodiment is based on a leg flexion and extension device in the field of general health, comprising two pads 1, a large gear 2 is installed between the rear parts of the two pads 1, and a pedal 201 is installed on the top of the large gear 2, and a back support plate 203 is movably installed inside both sides of the pad 1, and telescopic rods 202 are movably installed on both sides of the top of the large gear 2, and the movable part of the telescopic rod 202 is connected to the back support plate 203 through a rotating shaft; Specifically, a slider 5 is installed between the two pads 1 , and a pillow pad 501 is installed at the top middle position of the slider 5 , an adjustment disk 502 is installed on the front end surface of the pad 1 , and one end of the adjustment disk 502 is used in conjunction with the slider 5 .

[0025] When working: Figure 1As shown, the exerciser lies flat on the surface of the mat 1, lifts up the legs and places the soles of the feet on the surface of the pedal 201. At this time, one leg pushes forward and the other leg curls up. Repeated operations make the pedal 201 swing back and forth, thereby exercising the legs. The swing of the pedal 201 drives the large gear 2 to rotate back and forth. The reciprocating rotation of the large gear 2 drives the pedals 201 on both sides of the top surface to swing. Because the back support plate 203 is limited and movable inside the mat 1, it drives it to reciprocate a certain distance with the swing of the telescopic rod 202, and according to the height of the exerciser The limit button on the surface of the difference adjustable telescopic rod 202 is also because a slider 5 is movably installed inside the pad 1 in front of the back support plate 203, and a pillow pad 501 is installed at the top middle position of the slider 5. When used in conjunction with the adjustment disk 502, it can be used for people with different neck lengths to support the neck and head of the exerciser. Therefore, the movement of the telescopic rod 202 drives the back support plate 203 to slide, which can perform a rolling massage on the back of the exerciser, avoiding tension and accelerated fatigue of the back during leg stretching, allowing the exerciser to exercise in a relaxed state and increase the exercise time. Example 2

[0026] On the basis of Example 1: like Figures 2 to 4 As shown, this embodiment is based on the leg flexion and extension device in the field of big health. Furthermore, small gears 3 are installed inside the pads 1 on both sides of the large gear 2, and a cam 301 is fixedly installed on the top of the small gear 3, and a fan blade 302 is fixedly installed on the top of the cam 301. A piston tube 303 is installed inside the pad 1, and the movable part of the piston tube 303 is located on the rotation path of the cam 301.

[0027] When working: Figures 2 to 4 As shown, based on the reciprocating rotation of the large gear 2, the rotation of the large gear 2 will also drive the two sets of meshing small gears 3 to rotate. Since there are differences in the diameters and teeth of the large gear 2 and the small gear 3, the large gear 2 can drive the small gear 3 to rotate at a larger angle and faster speed. The small gear 3 will drive the cam 301 and the fan blade 302 to rotate. The fan blade 302 is a common blowing part in the prior art. Its rapid rotation can produce blowing. No rotating blowing is performed here, and the air flow can be accelerated. By accelerating the air flow, the calf of the exerciser can be cooled, and the combination of work and rest can reduce the fatigue of exercise. Example 3

[0028] Based on Examples 1 and 2: like Figure 3 and Figure 4As shown, this embodiment is based on the leg flexion and extension device in the field of general health. Furthermore, a leg placement platform 4 is installed on the top of the pad 1, and a soft rubber pad 402 is installed on the front end surface of the leg placement platform 4. A spring pull-out plate 401 is movably installed at the rear of the leg placement platform 4, and the bottom of the spring pull-out plate 401 is connected to the output part of the piston tube 303 through a hose.

[0029] When working: Figure 3 and Figure 4 As shown, based on the rotation of the cam 301 and the extension and retraction movement of the legs of the exerciser, the leg placement platform 4 and the spring pull-out plate 401 can be arranged so that the calves of the exerciser are located on the surface of the spring pull-out plate 401, and the heels are located at the end edge of the spring pull-out plate 401. The spring pull-out plate 401 can form a supporting effect on the legs, and a spring is arranged at the internal connection position between the leg placement platform 4 and the spring pull-out plate 401. When the spring pull-out plate 401 contracts, it provides a certain resistance, thereby increasing the intensity of the exercise, and also facilitates the ejection and reset of the spring pull-out plate 401. Therefore, the arrangement of the spring pull-out plate 401 can form a certain support for the leg extension process, avoiding fatigue caused by the legs hanging in the air for too long. As shown in the pinion 3, since the movable part of the piston tube 303 is located on the rotation path of the cam 301, the reciprocating swing of the cam 301 can squeeze the movable part of the piston tube 303, and the telescopic movement of the movable part of the piston tube 303 can drive the movement of the internal piston. When the piston moves, it can squeeze and blow air, and the blown gas is connected to the spring pull-out plate 401 through a hose. Two interconnecting grooves are provided at the edge of the top surface of the spring pull-out plate 401, so the air can be blown out from the interconnecting grooves and cool down the legs of the exerciser, thereby improving the fun and comfort of the exercise process. Example 4

[0030] Based on Examples 1 to 3: like Figure 2 and Figure 3 As shown, this embodiment is based on the leg flexion and extension device in the field of general health. Furthermore, a pushing rod 403 is installed inside the leg placement platform 4 through a through hole. One end of the pushing rod 403 is connected to the top of the cam 301, and the other end of the pushing rod 403 is used in conjunction with the soft rubber pad 402.

[0031] When working: Figure 2 and Figure 3As shown, based on the reciprocating rotation of the cam 301, the rotation of the cam 301 can drive the top rotatably connected push rod 403 to move, that is, the push rod 403 performs stretching and ejecting movements inside the leg placement platform 4. In addition, because one end of the push rod 403 is connected to the soft rubber pad 402, the reciprocating movement of the push rod 403 can drive the soft rubber pad 402 to be ejected or contracted during exercise, thereby lightly tapping the thigh surface of the exerciser, thereby achieving a massage effect, and also serving as an auxiliary exercise. Example 5

[0032] Based on Examples 1 to 4: like Figure 1 , Figure 5 and Figure 6 As shown, this embodiment is based on the leg flexion and extension device in the field of general health. Furthermore, a massage component is provided on the surface of the pillow pad 501, and the massage component is located at the surface edge of the pillow pad 501. The massage component may include foam or rubber material. A limiting slide plate is installed on the surface of the slider 5, and a spring is installed inside the limiting slide plate. A wedge block 601 is installed inside the limiting slide plate. The top of the wedge block 601 is connected to the bottom of the pillow pad 501 through a connecting rod. A groove is provided on the surface of the slider 5, and an adjusting push plate 6 is installed at the front end of the back support plate 203, and the adjusting push plate 6 is located inside the groove and used in conjunction with the wedge block 601.

[0033] When working: Figure 1 , Figure 5 and Figure 6 As shown, based on the reciprocating movement of the back support plate 203, the movement of the back support plate 203 can drive the synchronous movement of the adjusting push plate 6. Due to the inclined structure of the wedge block 601, the ejection of the adjusting push plate 6 can squeeze the wedge block 601 to move to one side. Since a limiting slide plate is installed on the surface of the slider 5, and a spring is installed inside the limiting slide plate, the wedge block 601 makes a linear motion in the limiting slide plate. The movement of the wedge block 601 can drive one side of the pillow pad 501 to deform and tend to the neck or head skin of the exerciser. The foam or rubber material on the surface is arranged, and the reciprocating deformation movement of one side of the pillow pad 501 can massage the neck or head of the exerciser. The exerciser can exercise all extra parts while reading or playing with a mobile phone, and improve physical fitness by combining work and rest. Example 6

[0034] In addition, if Figure 7 As shown, the method of using the leg flexion and extension device based on the field of big health: Step 1: Leg exercise: The exerciser lies flat on the surface of the mat 1, lifts his legs and places his feet on the surface of the pedal 201, at this time, one leg is pushed forward and the other is curled up, and the pedal 201 is repeatedly operated to form a reciprocating swing, thereby exercising the legs; Step 2: Back massage: The movement of the telescopic rod 202 drives the back support plate 203 to slide, so as to perform rolling massage on the back of the exerciser; Step 3: Heat dissipation: The small gear 3 drives the cam 301 and the fan blade 302 to rotate, thereby accelerating the air flow, so that the lower leg of the exerciser can be cooled, and the combination of work and rest can reduce the fatigue of exercise; Step 4: Reduce fatigue: The arrangement of the spring pull-out plate 401 can provide a certain support for the leg extension process to avoid fatigue caused by the legs hanging in the air for too long. Two interconnected grooves are arranged at the edge of the top surface of the spring pull-out plate 401 to cool down the legs of the exerciser and improve the fun and comfort of the exercise process; Step 5: Thigh exercise: The push rod 403 performs stretching and pushing movements inside the leg placement platform 4, which can lightly tap the surface of the thigh of the exerciser, thereby achieving a massage effect and also serving as an auxiliary exercise. Step 6: Neck massage: The movement of the wedge block 601 can cause one side of the pillow pad 501 to deform and move toward the neck or head skin of the exerciser to massage the neck or head of the exerciser.

[0035] The working principle of the present invention is as follows: Figure 1 As shown, the exerciser lies flat on the surface of the mat 1, lifts up the legs and places the soles of the feet on the surface of the pedal 201. At this time, one leg pushes forward and the other leg curls up. Repeated operations make the pedal 201 swing back and forth, thereby exercising the legs. The swing of the pedal 201 drives the large gear 2 to rotate back and forth. The reciprocating rotation of the large gear 2 drives the pedals 201 on both sides of the top surface to swing. Because the back support plate 203 is limited and movable inside the mat 1, it drives it to reciprocate a certain distance with the swing of the telescopic rod 202, and according to the height of the exerciser The limit button on the surface of the difference adjustable telescopic rod 202 is also because a slider 5 is movably installed inside the pad 1 in front of the back support plate 203, and a pillow pad 501 is installed at the top middle position of the slider 5. When used with the adjustment disk 502, it can be used for people with different neck lengths to form a support for the neck and head of the exerciser. Therefore, the movement of the telescopic rod 202 drives the back support plate 203 to slide, which can perform rolling massage on the back of the exerciser, avoiding tension and fatigue of the back during leg extension, allowing the exerciser to exercise in a relaxed state and increase the exercise time; like Figures 2 to 4As shown, on the basis of the reciprocating rotation of the large gear 2, the rotation of the large gear 2 will also drive the two sets of meshing small gears 3 to rotate. Due to the difference in diameter and teeth between the large gear 2 and the small gear 3, the large gear 2 can drive the small gear 3 to rotate at a larger angle and faster speed. The small gear 3 will drive the cam 301 and the fan blade 302 to rotate. The fan blade 302 is a common blowing part in the prior art. Its rapid rotation can generate blowing. Rotating blowing is not performed here. It is sufficient to speed up the air flow. By speeding up the air flow, the lower leg of the exerciser can be cooled, and the combination of work and rest can reduce the fatigue of exercise. like Figure 3 and Figure 4 As shown, based on the rotation of the cam 301 and the extension and retraction movement of the legs of the exerciser, the leg placement platform 4 and the spring pull-out plate 401 are arranged so that the calves of the exerciser can be located on the surface of the spring pull-out plate 401, and the heel part is located at the end edge of the spring pull-out plate 401. The spring pull-out plate 401 can form a supporting effect on the legs, and a spring is arranged at the internal connection position between the leg placement platform 4 and the spring pull-out plate 401. When the spring pull-out plate 401 contracts, it provides a certain resistance, thereby increasing the intensity of the exercise, and it is also convenient for the spring pull-out plate 401 to be ejected and reset. Therefore, the arrangement of the spring pull-out plate 401 can provide a support for the legs. The legs are supported to a certain extent during the exercise, so as to avoid fatigue caused by the legs being suspended in the air for too long. As shown in the pinion 3, since the movable part of the piston tube 303 is located on the rotation path of the cam 301, the reciprocating swing of the cam 301 can squeeze the movable part of the piston tube 303, and the telescopic movement of the movable part of the piston tube 303 can drive the movement of the internal piston. When the piston moves, it can squeeze and blow air, and the blown gas is connected to the spring pull-out plate 401 through a hose. Two intercommunication grooves are provided at the edge of the top surface of the spring pull-out plate 401, so the air can be blown out from the intercommunication grooves and cool down the legs of the exerciser, thereby improving the fun and comfort of the exercise process. like Figure 2 and Figure 3 As shown, on the basis of the reciprocating rotation of the cam 301, the rotation of the cam 301 can drive the top rotationally connected push rod 403 to move, that is, the push rod 403 performs stretching and ejecting movements inside the leg placement platform 4. In addition, because one end of the push rod 403 is connected to the soft rubber pad 402, the reciprocating movement of the push rod 403 can drive the soft rubber pad 402 to be ejected or contracted during exercise, thereby lightly tapping the surface of the thigh of the exerciser, thereby achieving a massage effect, and also playing a role in assisting exercise; like Figure 1 , Figure 5 and Figure 6As shown, based on the reciprocating movement of the back support plate 203, the movement of the back support plate 203 can drive the synchronous movement of the adjusting push plate 6. Due to the inclined structure of the wedge block 601, the ejection of the adjusting push plate 6 can squeeze the wedge block 601 to move to one side. Since a limiting slide plate is installed on the surface of the slider 5, and a spring is installed inside the limiting slide plate, the wedge block 601 makes a linear motion in the limiting slide plate. The movement of the wedge block 601 can drive one side of the pillow pad 501 to deform and tend to the neck or head skin of the exerciser. The foam or rubber material on the surface is arranged, and the reciprocating deformation movement of one side of the pillow pad 501 can massage the neck or head of the exerciser. The exerciser can exercise all extra parts while reading or playing with a mobile phone, and improve physical fitness by combining work and rest.

8. A method for using a leg flexion and extension device based on the field of health, applied to a leg flexion and extension device based on the field of health as claimed in any one of claims 1 to 7, characterized in that: Here are the steps: Step 1: Leg exercise: The exerciser lies flat on the surface of the mat (1), lifts his legs and places the soles of his feet on the surface of the pedal (201), at which time one leg is pushed forward and the other is curled up, and the pedal (201) is repeatedly operated to form a reciprocating swing, thereby exercising the legs; Step 2: back massage: the movement of the telescopic rod (202) drives the back support plate (203) to slide, so as to perform rolling massage on the back of the exerciser; Step 3: Heat dissipation: The pinion (3) drives the cam (301) and the fan blade (302) to rotate, thereby accelerating the air flow, thereby dissipating heat from the calf of the exerciser, combining work and rest to reduce exercise fatigue; Step 4: Reduce fatigue: The arrangement of the spring pull-out plate (401) can provide a certain support for the leg extension process, avoiding fatigue caused by the legs hanging in the air for too long. Two interconnected grooves are arranged at the edge of the top surface of the spring pull-out plate (401), which can cool down the legs of the exerciser and improve the fun and comfort of the exercise process; Step 5: Thigh exercise: The push rod (403) performs stretching and pushing movements inside the leg placement platform (4), which can lightly tap the surface of the thigh of the exerciser, thereby achieving a massage effect and also serving as an auxiliary exercise. Step 6: Neck massage: The movement of the wedge-shaped block (601) can cause one side of the pillow (501) to deform and move toward the neck or head skin of the exerciser to massage the neck or head of the exerciser.
