Description

Technical Field

[0001] The present invention relates to the technical field of sports equipment, and specifically to a sports machine for exercising the legs during sports. Background Art

[0002] Most of the operators in positions such as drivers and office clerks need to sit for a long time. Prolonged sitting can cause damage to the legs and joints. If not exercised in time, it will cause permanent damage to the legs and joints. Physical exercise refers to the physical activities that people choose according to their physical needs, using various sports means, combined with natural forces and health measures, with the purpose of developing the body, enhancing health, strengthening physical fitness, regulating the mind, enriching cultural life, and dominating leisure time. Among them, leg exercise is an indispensable part of physical exercise. When doing leg physical exercise, in addition to exercises such as running, some sports equipment is sometimes needed to conduct strength training on the legs.

[0003] When exercising the legs, it usually takes a long time for the exerciser to help muscle recovery and enhancement. However, after the exerciser exercises the legs for a long time, the legs gradually become fatigued and it is difficult to keep up with the exercise rhythm of the exercise equipment. Therefore, we propose a sports machine for exercising the legs during sports. Summary of the Invention

[0004] To solve the above technical problems, the present invention provides a sports machine for exercising the legs during sports, including:

[0005] A bottom-mounted long frame, with a seat board provided on one side of the bottom-mounted long frame;

[0006] A fixed pedal, with a push spring provided on one side of the fixed pedal;

[0007] A buffer device for slowing down the rebounding and pushing speed of the push spring;

[0008] An adaptive footrest device for adaptively anti-slip adsorption on the soles of the exercisers;

[0009] One side of the bottom-mounted long frame is fixedly connected to one side of the seat board, the top of the bottom-mounted long frame is fixedly connected to the bottom of the fixed pedal, one side of the fixed pedal is fixedly connected to one end of the push spring, the end of the push spring away from the fixed pedal is fixedly connected to one side of the adaptive footrest device, one side of the adaptive footrest device close to the push spring is fixedly connected to one end of the buffer device, and the side of the buffer device away from the adaptive footrest device is fixedly connected to one side of the fixed pedal;

[0010] Among them, the buffer device includes:

[0011] A circular housing, on the outer side of which there are circular air holes. By opening circular air holes on the surface of the circular housing that are smaller than the air extraction negative pressure of the built-in circular plate, the return speed of the adapted footrest device is slowed down to prevent potential safety hazards caused by the exerciser's physical strength gradually declining after long-term leg exercises and being easily affected by the thrust of the push spring, making it difficult to keep up with the return speed.

[0012] A built-in circular plate, on one side of which there is a long baffle. When the long baffle moves, it gradually covers and blocks the circular air holes on the circular housing, preventing the inside of the circular housing from always maintaining normal pressure and making it difficult to apply a buffering effect to the adapted footrest device through pressure adjustment.

[0013] There are multiple circular air holes, and the multiple circular air holes are distributed on the outer side of the circular housing. The outer side of the built-in circular plate is slidably connected to the inner wall of the circular housing. One side of the long baffle is fixedly connected to one side of the built-in circular plate. The side of the long baffle away from the built-in circular plate penetrates the circular housing and is slidably connected to the circular housing. There are multiple long baffles, and the multiple long baffles are distributed at positions on the inner wall of the circular housing that are horizontally aligned with the circular air holes.

[0014] One side of the circular housing is fixedly connected to one side of the fixed pedal. The side of the long baffle away from the built-in circular plate is fixedly connected to one side of the adapted footrest device.

[0015] On the side of the built-in circular plate close to the long baffle, there is a fixed circular rod fixedly connected. By setting a circular housing on one side of the elastically connected adapted footrest device and cooperating with the fixed circular rod for its movement and sliding limit, it is prevented that the adapted footrest device elastically connected by the push spring is easily affected by uneven thrust and is displaced, affecting the exercise effect. On the side of the built-in circular plate away from the fixed circular rod, there is a side top block fixedly connected. By setting a side top block on one side of the built-in circular plate, the built-in circular plate is separated at a certain distance from one end of the fixed pedal, preventing the negative pressure formed when the built-in circular plate completely blocks the circular housing as it moves with the adapted footrest device and fits with the fixed pedal from being easily pushed open by the push spring.

[0016] The end of the fixed circular rod away from the built-in circular plate penetrates the circular housing and is slidably connected to the circular housing. The end of the fixed circular rod away from the built-in circular plate is fixedly connected to one side of the adapted footrest device.

[0017] Further, the adapted footrest device includes a concave footrest. One side of the concave footrest is fixedly connected with a cleaning mechanism. An elliptical corner groove is formed on the side of the concave footrest close to the cleaning mechanism. The elliptical corner groove facilitates the placement of the exerciser's sole and limits it, preventing the phenomenon that the sole of the exerciser detaches from the concave footrest and shifts to the outside during leg pressure exercise, which is likely to cause safety hazards. A square through-hole is formed in the inner wall of the elliptical corner groove, and a square ventilation plate is fixedly connected to the inner wall of the square through-hole. When the square ventilation plate is filled with gas, it gradually inflates the square sponge, causing the square sponge to gradually expand and recover, preventing the square sponge that has been stepped on by the exerciser for a long time from gradually losing its elastic resilience and affecting its use effect. One side of the square ventilation plate is fixedly connected with a high-pressure air pump. A ventilation small hole is formed on the side of the square ventilation plate away from the high-pressure air pump. A square sponge is fixedly connected to the side of the square ventilation plate close to the ventilation small hole. By arranging the square sponge in the elliptical corner groove to make flexible contact with the sole of the exerciser directly, it prevents the sole of the exerciser from being in long-term pushing contact with the plate, which is likely to make the exerciser uncomfortable and is not conducive to long-term leg exercise. A ventilation round hole is formed on one side of the square sponge. By forming the ventilation round hole on the square sponge, it directly adsorbs the sole of the exerciser, preventing the sole of the exerciser from being too smooth and prone to uneven force application and sliding offset, which affects the effect of leg exercise. One end of a push spring is fixedly connected to the side of the concave footrest away from the cleaning mechanism. One side of a long baffle is fixedly connected to the side of the concave footrest away from the cleaning mechanism. One end of a fixed round rod is fixedly connected to the side of the concave footrest away from the cleaning mechanism. There are two elliptical corner grooves, and the two elliptical corner grooves are distributed on one side of the concave footrest. There are two cleaning mechanisms, and the two cleaning mechanisms are distributed at the position at the bottom of the elliptical corner groove on one side of the concave footrest. One side of the high-pressure air pump is fixedly connected to the side of the concave footrest away from the cleaning mechanism. The square ventilation plate is set as a square plate body with a cavity inside. There are multiple ventilation small holes, and the multiple ventilation small holes are distributed on one side of the square ventilation plate. There are multiple ventilation round holes, and the multiple ventilation round holes are distributed on one side of the square sponge.

[0018] Further, the cleaning mechanism includes side support plates, and a square cushion is fixedly connected to the top of the side support plates. By arranging the square cushion on the top of the side support plates, the heel part of the exerciser is flexibly supported, preventing the heel of the exerciser from lacking support force after long-term exercise or causing pain due to long-term extrusion contact with the rigid plate, which affects the exercise effect. An inclined scraper is fixedly connected to the bottom of the side support plates. When the inclined scraper moves, the dust swept away by the side brush is scraped to the side far away from the straight baffle and discharged, preventing a part of the cleaned dust from still accumulating on the bottom long frame and affecting the subsequent movement of the concave pedal. A straight baffle is fixedly connected to one side of the inclined scraper. By arranging the straight baffle on one side of the inclined scraper, the position near the inner side of the bottom long frame is covered and blocked, preventing a part of the dust from being pushed to the inner side of the bottom long frame and accumulating and being difficult to handle when the inclined scraper scrapes the dust. A side brush is fixedly connected to the side of the straight baffle close to the inclined scraper. When the side brush moves along with the straight baffle, it frictionally cleans the top of the bottom long frame, preventing excessive dust from gradually accumulating on the surface of the top of the bottom long frame in contact with the concave pedal after long-term use, which affects the movement of the concave pedal. One side of the side support plate is fixedly connected to one side of the concave pedal, one side of the inclined scraper is fixedly connected to one side of the concave pedal, the straight baffle is arranged on one side of the inclined scraper and is horizontally aligned with the bottom long frame, and a plurality of side brushes are provided, and the plurality of side brushes are distributed on one side of the straight baffle.

[0019] The present invention provides a sports machine for exercising the legs in sports. It has the following beneficial effects:

[0020] 1. For the sports machine for exercising the legs in sports, by opening circular air holes smaller than the air extraction negative pressure of the built-in circular plate on the surface of the circular housing, the return speed of the adapted pedal device is slowed down, preventing potential safety hazards caused by the exerciser's physical strength gradually decreasing after long-term leg exercise and being easily affected by the thrust of the push spring and being difficult to keep up with the return speed. By arranging square sponges in the elliptical grooves to directly make flexible contact with the soles of the exercisers, it is prevented that the soles of the exercisers are in long-term push contact with the influencing plates, which is likely to cause discomfort to the exercisers and is not conducive to long-term leg exercise. When the side brush moves along with the straight baffle, it frictionally cleans the top of the bottom long frame, preventing excessive dust from gradually accumulating on the surface of the top of the bottom long frame in contact with the concave pedal after long-term use, which affects the movement of the concave pedal.

[0021] 2. The sports machine for exercising the legs in this sport is provided with a buffer device. When the long baffle moves, it gradually covers and seals the circular air holes on the circular housing, preventing the inside of the circular housing from always maintaining a normal pressure state, which makes it difficult to apply a buffering effect to the adapted footrest device through pressure adjustment. By setting a side top block on one side of the built-in circular plate to separate the built-in circular plate at a position at a certain distance from one end of the fixed pedal, it is prevented that when the built-in circular plate moves with the adapted footrest device to fit with the fixed pedal and completely seals the circular housing, the negative pressure formed is not easily pushed open by the compression spring. By opening circular air holes on the surface of the circular housing that are smaller than the air extraction negative pressure of the built-in circular plate, the return speed of the adapted footrest device is slowed down, preventing potential safety hazards caused by the exerciser's physical strength gradually declining after long-term leg exercise and being easily affected by the thrust of the compression spring and having difficulty keeping up with the return speed. By setting a circular housing on one side of the elastically connected adapted footrest device to cooperate with the fixed round rod for its movement and perform sliding limit on it, it is prevented that the adapted footrest device elastically connected to the fixed pedal through the compression spring is easily affected by uneven thrust and offsets, affecting the exercise effect.

[0022] 3. The sports machine for exercising the legs in this sport is provided with an adapted footrest device. By setting a square sponge in the elliptical corner groove to directly make flexible contact with the exerciser's sole, it is prevented that the exerciser's sole is in long-term pushing contact with the influencing plate, which is likely to cause discomfort to the exerciser and is not conducive to long-term leg exercise. By opening ventilation round holes on the square sponge to directly adsorb the exerciser's sole, it is prevented that when the exerciser's sole is too smooth, it is easy to have uneven force application and slide and offset, affecting the effect of leg exercise. By opening an elliptical corner groove on one side of the concave footrest to facilitate the placement of the exerciser's sole and limit it, it is prevented that when the exerciser is performing leg pressure exercise, the sole detaches from the concave footrest and offsets to the outside, which is likely to cause safety hazards. When the square ventilation plate is filled with gas, it gradually inflates the square sponge, causing the square sponge to gradually expand and recover, preventing the square sponge that has been stepped on by the exerciser for a long time from gradually losing its elastic resilience and affecting its use effect.

[0023] 4. The sports machine for exercising the legs in this sport is provided with a cleaning mechanism. When the side brush moves along with the straight baffle, it frictionally sweeps the top of the bottom long frame to prevent excessive dust from gradually accumulating on the surface where the top of the bottom long frame contacts the concave footrest after long-term use, which may affect the movement of the concave footrest. When the inclined scraper moves, it scrapes the dust swept by the side brush to the side away from the straight baffle for discharge, preventing some of the cleaned dust from still accumulating on the bottom long frame and affecting the subsequent movement of the concave footrest. By setting a straight baffle on one side of the inclined scraper, the position of the bottom long frame near the inner side is covered and blocked to prevent some dust from being pushed to the inner side of the bottom long frame by the inclined scraper during dust scraping, making it difficult to handle. By setting a square cushion on the top of the side support plate, the heel part of the exerciser is flexibly supported to prevent the lack of support force of the heel or pain caused by long-term extrusion contact with the hard plate after long-term exercise, which may affect the exercise effect.

[0040] Among them, the buffer device 5 includes:

[0041] Circular housing 501, and circular air holes 502 are arranged on the outer side of the circular housing 501;

[0042] There is an inner circular plate 503, and a long baffle 504 is arranged on one side of the inner circular plate 503;

[0043] There are multiple circular air holes 502, and the multiple circular air holes 502 are distributed on the outer side of the circular housing 501. The outer side of the inner circular plate 503 is slidably connected to the inner wall of the circular housing 501. One side of the long baffle 504 is fixedly connected to one side of the inner circular plate 503. The side of the long baffle 504 away from the inner circular plate 503 penetrates through the circular housing 501 and is slidably connected to the circular housing 501. There are multiple long baffles 504, and the multiple long baffles 504 are distributed at positions on the inner wall of the circular housing 501 that are horizontally aligned with the circular air holes 502;

[0044] One side of the circular housing 501 is fixedly connected to one side of the fixed pedal 3. The side of the long baffle 504 away from the inner circular plate 503 is fixedly connected to one side of the adapted foot pedal device 6;

[0045] A fixed circular rod 505 is fixedly connected to the side of the inner circular plate 503 close to the long baffle 504, and a side top block 506 is fixedly connected to the side of the inner circular plate 503 away from the fixed circular rod 505;

When in use, the exerciser sits on the seat board 2 and places his feet on the adaptive footrest device 6 and pushes the adaptive footrest device 6 to compress the push spring 4. When the exerciser no longer pushes the adaptive footrest device 6, the push spring 4 pushes the adaptive footrest device 6 back through the extension force. When the adaptive footrest device 6 moves back, the buffering effect of the buffer device 5 slows down the return speed.

By setting a circular shell 501 and a fixed circular rod 505 on one side of the elastically connected adaptive pedal device 6 to cooperate with its movement and slide limit it,

[0047] See also Figures 1 - 8, the present invention provides a sports machine for exercising the legs in sports: The adapted foot pedal device 6 includes a concave foot pedal 601. One side of the concave foot pedal 601 is fixedly connected to a cleaning mechanism 602. An elliptical angular groove 603 is opened on one side of the concave foot pedal 601 close to the cleaning mechanism 602. A square through hole 604 is opened on the inner wall of the elliptical angular groove 603. A square air-permeable plate 605 is fixedly connected to the inner wall of the square through hole 604. A high-pressure air pump 606 is fixedly connected to one side of the square air-permeable plate 605. Ventilation small holes 607 are opened on the side of the square air-permeable plate 605 away from the high-pressure air pump 606. A square sponge 608 is fixedly connected to the side of the square air-permeable plate 605 close to the ventilation small holes 607. Ventilation round holes 609 are opened on one side of the square sponge 608. One end of a pushing spring 4 is fixedly connected to the side of the concave foot pedal 601 away from the cleaning mechanism 602. One side of a long baffle 504 is fixedly connected to the side of the concave foot pedal 601 away from the cleaning mechanism 602. One end of a fixed round rod 505 is fixedly connected to the side of the concave foot pedal 601 away from the cleaning mechanism 602. There are two elliptical angular grooves 603, and the two elliptical angular grooves 603 are distributed on one side of the concave foot pedal 601. There are two cleaning mechanisms 602, and the two cleaning mechanisms 602 are distributed at the position at the bottom of the elliptical angular grooves 603 on one side of the concave foot pedal 601. One side of the high-pressure air pump 606 is fixedly connected to the side of the concave foot pedal 601 away from the cleaning mechanism 602. The square air-permeable plate 605 is set as a square plate body with a cavity inside. There are multiple ventilation small holes 607, and the multiple ventilation small holes 607 are distributed on one side of the square air-permeable plate 605. There are multiple ventilation round holes 609, and the multiple ventilation round holes 609 are distributed on one side of the square sponge 608;

[0048] The cleaning mechanism 602 includes side support plates 6021. A square cushion 6022 is fixedly connected to the top of the side support plates 6021. An inclined scraper 6023 is fixedly connected to the bottom of the side support plates 6021. A straight baffle 6024 is fixedly connected to one side of the inclined scraper 6023. A side brush 6025 is fixedly connected to the side of the straight baffle 6024 close to the inclined scraper 6023. One side of the side support plates 6021 is fixedly connected to one side of the concave footrest 601. One side of the inclined scraper 6023 is fixedly connected to one side of the concave footrest 601. The straight baffle 6024 is arranged on one side of the inclined scraper 6023 and is horizontally aligned with the bottom long frame 1. There are multiple side brushes 6025, and the multiple side brushes 6025 are distributed on one side of the straight baffle 6024. When in use, the exerciser needs to place both feet on the square sponge 608 in the elliptical corner groove 603 and apply a thrust to the concave footrest 601 for leg exercise. By arranging the square sponge 608 in the elliptical corner groove 603 to directly make flexible contact with the soles of the exerciser's feet, after the exerciser's feet are placed in the elliptical corner groove 603 and compress the square sponge 608, the high-pressure air pump 606 evacuates the square ventilation plate 605. When the square ventilation plate 605 is evacuated by the high-pressure air pump 606, it adsorbs the square sponge 608 on one side and adsorbs the soles of the exerciser's feet through the ventilation round holes 609 opened on the square sponge 608. By opening the ventilation round holes 609 on the square sponge 608 to directly adsorb the soles of the exerciser's feet, by opening the elliptical corner groove 603 on one side of the concave footrest 601, it is convenient for the placement of the exerciser's soles and limits them. After the exerciser finishes exercising, the high-pressure air pump 606 inflates the square ventilation plate 605. When the square ventilation plate 605 is filled with gas, it gradually inflates the square sponge 608 to make the square sponge 608 gradually expand and recover. When the push spring 4 drives the concave footrest 601 to move back by the stretching force, it drives the cleaning mechanism 602 on one side to move back together. When the concave footrest 601 moves back, it drives the side support plates 6021, the inclined scraper 6023, and the straight baffle 6024 on one side to move back together. When the straight baffle 6024 moves back, it drives the side brush 6025 on one side to move together. When the side brush 6025 moves with the straight baffle 6024, it frictionally cleans the top of the bottom long frame 1. When the inclined scraper 6023 moves, it scrapes the dust swept by the side brush 6025 to the side far from the straight baffle 6024 and discharges it. By arranging the straight baffle 6024 on one side of the inclined scraper 6023 to cover and resist the position of the bottom long frame 1 close to the inside, by arranging the square cushion 6022 on the top of the side support plates 6021 to flexibly support the part of the exerciser's heel.

[0049] When the present invention is in operation, the exerciser sits on the seat 2 and places his feet on the adaptive footrest device 6 and pushes the adaptive footrest device 6 to compress the push spring 4. When the exerciser stops pushing the adaptive footrest device 6, the push spring 4 pushes the adaptive footrest device 6 back through the extension force. When the adaptive footrest device 6 moves back, the buffering effect of the buffer device 5 slows down the return speed. When the adaptive footrest device 6 is pushed, it drives the long baffle 504 and the fixed round rod 505 on one side to move toward the inside of the circular shell 501. When the long baffle 504 moves, it drives the built-in circular plate 503 on one side to move together. When the long baffle 504 moves, it gradually covers and blocks the circular air hole 502 on the circular shell 501, and the built-in circular plate 503 moves toward the fixed pedal 3. When the pedal 6 loses its thrust and moves back, the long baffle 504, the fixed round rod 505, the built-in circular plate 503 and the side top block 506 on one side are driven to move back together. When the built-in circular plate 503 moves back in the direction away from the fixed pedal 3, the external air is sucked into the circular shell 501 through the circular air hole 502. By opening a hole smaller than the built-in circular plate 503 on the surface of the circular shell 501 to remove the air, the air in the circular shell 501 is sucked into the circular shell 501. The circular air hole 502 is compressed to slow down the return speed of the adaptive pedal device 6. A circular shell 501 is set on one side of the elastically connected adaptive pedal device 6 to cooperate with its movement and slide limit it. When using the sports equipment, the exerciser needs to place his feet on the square sponge 608 in the elliptical angle groove 603 and apply thrust to the concave foot pedal 601 to perform leg exercises. The square sponge 608 is set in the elliptical angle groove 603 to directly and flexibly contact the soles of the exerciser's feet. After the exerciser's feet are placed in the elliptical angle groove 603 and the square sponge 608 is compressed, the square ventilation plate 605 is evacuated by the high-pressure air pump 606, and the square ventilation plate 605 is pumped by the high-pressure air pump 606. When the air is pumped out, the square sponge 608 on one side will be adsorbed and the sole of the exerciser's foot will be adsorbed through the ventilation circular hole 609 provided on the square sponge 608. The ventilation circular hole 609 is provided on the square sponge 608 to directly adsorb the sole of the exerciser's foot. The elliptical angle groove 603 is provided on one side of the concave foot pedal 601 to facilitate the placement of the sole of the exerciser's foot and limit it. After the exerciser finishes exercising, the square ventilation plate 605 is inflated with air through the high-pressure air pump 606. When the square ventilation plate 605 is full of gas, the air is gradually inflated into the square sponge 608, causing the square sponge 608 to gradually expand and recover. The pushing spring 4 pushes the concave foot pedal 601 back through its extension force, driving the cleaning mechanism 602 on one side to move back together.When the concave pedal 601 moves back, it drives the side support plate 6021, the inclined scraper 6023 and the straight baffle 6024 on one side to move back together. When the straight baffle 6024 moves back, it drives the side brush 6025 on one side to move together. As the side brush 6025 moves with the straight baffle 6024, it frictionally cleans the top of the bottom long frame 1. When the inclined scraper 6023 moves, it scrapes off the dust cleaned by the side brush 6025 to the side far away from the straight baffle 6024 and discharges it. By setting the straight baffle 6024 on one side of the inclined scraper 6023, the position of the bottom long frame 1 close to the inner side is covered and resisted. By setting the square cushion 6022 on the top of the side support plate 6021, the part of the exerciser's heel is flexibly supported.,
