The flow regulating valve is installed in the valve cavity and can rotate in the valve cavity. The flow regulating valve part located in the valve cavity is horizontally penetrated by an adjusting channel. When the adjusting channel rotates with the flow regulating valve, the adjusting channel is connected to or disconnected from the opening to open or close the air passage, and when the air passage is in the open state, the flow regulating valve is rotated to increase or decrease the connecting area between the adjusting channel and the opening to adjust the opening size of the air passage.

[0008] Furthermore, the top of the flow regulating valve passes through the top wall of the valve cavity, and a rotary cover is fixedly arranged thereon, and the flow regulating valve is driven to rotate in the valve cavity by the rotation of the rotary cover.

[0009] Furthermore, a limiting protrusion is provided on the bottom of the flow regulating valve, and the limiting protrusion rotates with the flow regulating valve. An arc-shaped limiting groove is provided on the bottom of the valve cavity on the rotation path of the limiting protrusion.

DETAILED DESCRIPTION

[0023] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] like Figures 1 to 5 As shown, the utility model provides a pedal machine, including a left pedal pad 10, a right pedal pad 20 and a connecting structure 30. The left pedal pad 10 and the right pedal pad 20 are both made of soft materials. A first air chamber 11 is provided in the left pedal pad 10, and a second air chamber 21 is provided in the right pedal pad 20. The first air chamber 11 and the second air chamber 21 are both used to contain gas. The two ends of the connecting structure 30 are respectively connected to the left pedal pad 10 and the right pedal pad 20, and an air passage 31 is provided therein. The air passage 31 is used to connect the first air chamber 11 and the second air chamber 21. Specifically, the soft material can be silicone or plastic, which is not limited here.

[0025] When the present invention is in use, the user's left foot steps on the left mat 10 with force, causing the volume of the first air chamber 11 to shrink, and the gas in the first air chamber 11 flows into the second air chamber 21 through the air passage 31. The gas in the second air chamber 21 increases, so that the right mat 20 expands and bounces the user's right foot upward. Conversely, the user steps on the right foot pedal with force with the right foot, and the gas in the first air chamber 11 increases, so that the left mat 10 expands and bounces the user's left foot upward, and so on and so forth, simulating the action of climbing stairs. The structure is relatively simple, the cost is low, and the effect is better. In addition, the gas circulates back and forth between the first air chamber 11 and the second air chamber 21 to avoid the linkage failure between the left mat 10 and the right mat 20, and the reliability is high. The present invention is easy to assemble, and only the left mat 10 and the right mat 20 need to be installed correspondingly at the left and right ends of the connecting structure 30.

[0026] Furthermore, a flow regulating valve 32 is provided in the connecting structure 30, and the flow regulating valve 32 is used to open or close the air passage 31, and is also used to adjust the opening size of the air passage 31. By adjusting the opening size of the air passage 31, the gas flow size flowing in the air passage 31 is controlled, thereby controlling the expansion speed of the first air chamber 11 or the second air chamber 21, and then controlling the speed at which the left mat 10 and the right mat 20 bounce the user's feet upward, thereby controlling the speed of the simulated climbing. Specifically, when the opening of the air passage 31 is large, the gas flowing in the air passage 31 is The gas flow in 31 is relatively large, and the speed at which the first air chamber 11 or the second air chamber 21 expands is relatively fast. Therefore, the speed at which the left mat 10 and the right mat 20 bounce the user's feet upward is relatively fast, and the speed of simulating climbing is relatively fast. When the opening of the air passage 31 is relatively small, the gas flow in the air passage 31 is relatively small, and the speed at which the first air chamber 11 or the second air chamber 21 expands is relatively slow. Therefore, the speed at which the left mat 10 and the right mat 20 bounce the user's feet upward is relatively slow, and the speed of simulating climbing is relatively slow. In addition, by closing the air passage 31, the gas in the two air chambers can be blocked from flowing mutually.

[0027] Specifically, a valve cavity 311 is provided in the air passage 31, and openings 3111 are respectively provided on the two side walls of the valve cavity 311 facing the first air chamber 11 and the second air chamber 21. The flow regulating valve 32 is installed in the valve cavity 311 and can rotate in the valve cavity 311. The flow regulating valve 32 located in the valve cavity 311 is laterally penetrated by a regulating channel 321. When the regulating channel 32 rotates with the flow regulating valve 32, it is connected to or disconnected from the opening 3111 to open or close the air passage 31. When the air passage 31 is in the open state, the flow regulating valve 32 is rotated to increase or decrease the flow. or reduce the communicating area between the regulating channel 321 and the opening 3111 to adjust the opening size of the air passage 31, so that when the communicating area is increased, the opening of the air passage 31 is increased, and the gas flow rate flowing in the air passage 31 is increased, thereby increasing the speed at which the left mat 10 and the right mat 20 bounce the user's feet upward; and when the communicating area is reduced, the opening of the air passage 31 is reduced, and the gas flow rate flowing in the air passage 31 is reduced, thereby reducing the speed at which the left mat 10 and the right mat 20 bounce the user's feet upward; when the regulating channel 321 and the opening are separated, the air passage 31 is closed;

[0028] Specifically, the top of the flow regulating valve 32 passes through the top wall of the valve cavity 311, and a rotary cover 322 is fixedly arranged thereon. The flow regulating valve 32 is driven to rotate in the valve cavity 311 by the rotation of the rotary cover 322. The rotary cover 322 is convenient for the user to operate and conveniently rotate the flow regulating valve 32. A sealing ring 324 is provided between the top of the flow regulating valve 32 and the valve cavity 311 to prevent air leakage.

[0029] Specifically, a limiting protrusion 323 is convexly provided at the bottom of the flow regulating valve 32, and the limiting protrusion 323 rotates with the flow regulating valve 32. The bottom of the valve cavity 311 is located on the rotation path of the limiting protrusion 323 and is provided with an arc-shaped limiting groove 312. The limiting protrusion 323 rotates with the flow regulating valve 32 in the limiting groove 312. When the limiting protrusion 323 rotates to abut against one end of the limiting groove 312, the regulating channel 321 and the opening 3111 are separated. When the limiting protrusion 323 rotates to abut against the other end of the limiting groove 312, the communicating area between the regulating channel 321 and the opening 3111 reaches a maximum value, that is, the opening 3111 and the regulating channel are connected. When the flow regulating valve 321 is blocked, the limiting protrusion 323 abuts against the side wall at one end of the limiting groove 312, and the flow regulating valve 32 cannot continue to rotate, and can only rotate in the opposite direction to connect the opening 3111 and the regulating channel 321, and continue to rotate to increase the connecting area between the two. When the connecting area between the opening 3111 and the regulating channel 321 reaches the maximum value, the flow regulating valve 32 cannot continue to rotate. At this time, the limiting protrusion 323 abuts against the side wall at the other end of the limiting groove 312, and can only rotate in the opposite direction to reduce the connecting area between the opening 3111 and the regulating channel 321 until the opening 3111 and the regulating channel 321 are blocked.

[0030] Furthermore, the base 40 is made of a hard material, and the left and right ends of the base 40 are respectively embedded in the bottom surfaces of the left mat 10 and the right mat 20, and the bottom surface of the base 40 and the bottom surfaces of the left mat 10 and the right mat 20 form a plane, so that the left mat 10 and the right mat 20 form a whole and are not easy to slide separately, so as to maintain stability during use;

[0031] Specifically, the connecting structure 30 is located between the left pedal pad 10 and the right pedal pad 20 and is fixedly mounted on the base 40 so that the connecting structure 30 is stable and not easy to move.

[0032] Furthermore, an air-inflating hole 50 for inflation is provided on the left mat 10 or the right mat 20, and a one-way valve is installed in the air-inflating hole 50 to inflate the left mat 10 or the right mat 20 according to the needs of the user.

[0033] Furthermore, the bottoms of the left mat 10 and the right mat 20 are respectively provided with grooves 60, and openings 61 are provided in the grooves 60. The two ends of the connecting structure 30 are respectively embedded in the grooves 60. The air passage 31 is respectively connected with the first air chamber 11 and the second air chamber 21 through the openings 61, so that the structure of the utility model is compact and the occupied volume is reduced. Seals 62 are respectively provided between the two openings 61 and the two ends of the connecting structure 30, so that the openings 61 and the connecting structure 30 are sealed and connected to ensure air tightness and prevent air leakage, so as to avoid the occurrence of insufficient gas in the first air chamber 11 and the second air chamber 21, resulting in poor effect of the left mat 10 or the right mat 20 against the user's foot and poor effect of simulating climbing stairs. Preferably, the seal 62 is a pipe made of PVC.

[0034] Furthermore, the left mat 10 and the right mat 20 are both made of elastic material, so that when all the gas in the first air chamber 11 flows to the second air chamber 12, or when all the gas in the second air chamber 12 flows to the first air chamber 11, the left mat 10 or the right mat 20 will not be broken, and the left mat 10 and the right mat 20 made of elastic material will rebound the user's feet when the user steps on them, providing damping for the user's stepping. When in use, the user needs to expend more effort to step on them, and the exercise effect is better.

[0035] Furthermore, the upper surfaces of the left mat 10 and the right mat 20 have anti-slip grooves 70 to prevent the user's feet from slipping when stepping on them. Hard air connection channels are respectively formed at the lower right portion of the left mat 10 and the lower left portion of the right mat 20. The air connection channels extend upward into the left mat 10 or the right mat 20 in the above-mentioned opening 60. The above-mentioned seal 62 is specifically arranged in the air connection channel, and the two ends of the connecting structure 30 are respectively inserted upward into the air connection channels of the left mat 10 and the right mat 20. The seal 62 maintains the air tightness of the two ends of the connecting structure and the air connection channel.
