Description

Technical Field

[0001] This application relates to the field of testing equipment technology, and in particular to a treadmill and treadmill belt pressure testing mechanism. Background Technology

[0002] Treadmills are a common piece of fitness equipment in homes and gyms, and they are the simplest type of home fitness equipment available today, making them the best choice for home fitness.

[0003] In related technologies, a treadmill includes a support frame and a running belt. Two rotating rollers are rotatably connected to the support frame, and the two rotating rollers are located at both ends of the support frame. The running belt is sleeved on the rotating rollers. When the treadmill is driven, the rotating rollers drive the running belt to rotate, and the user can run on the running belt.

[0004] Regarding the aforementioned technologies, prolonged use of a treadmill can lead to a decrease in the tension of the running belt, making it unable to maintain contact with the outer circumferential sidewall of the rotating roller, resulting in slippage of the rotating roller. There is still room for improvement. Summary of the Invention

[0005] In order to reduce the slippage of the rotating rollers caused by the decrease in tension of the running belt after prolonged use of the treadmill, this application provides a treadmill and a running belt pressure detection mechanism.

[0006] Firstly, the treadmill provided in this application adopts the following technical solution:

[0007] A treadmill includes a foot support frame, drive rollers, and a running belt. The number of drive rollers is at least two and they are rotatably connected to both ends of the foot support frame. The running belt is wound around the two drive rollers. One of the drive rollers has a first rotating shaft rotatably connected to both ends. Adjusting screws are rotatably connected to both sides of the foot support frame. The first rotating shaft is threaded onto the adjusting screws.

[0008] By adopting the above technical solution, the adjusting screw is rotatably connected to the foot pedal bracket. When the operator rotates the adjusting screw, the first rotating shaft threadedly connected to the adjusting screw moves back and forth in the direction of the running belt's movement, thereby driving the drive roller to move. This gradually tightens the running belt wound around the drive roller, thereby increasing the tension of the running belt and reducing the slippage of the drive roller when the tension decreases, which would otherwise affect the user experience.

[0009] Optionally, an adjusting block is fixedly connected to the end of the adjusting screw away from the first rotating axis, and the adjusting block is polygonal.

[0010] By adopting the above technical solution, the setting of the adjustment block allows the operator to directly hold the adjustment block for adjustment, or to use auxiliary tools to adjust the adjustment block. The polygonal design reduces the friction between the threads on the adjustment screw and the hand, while also providing a certain limit, reducing the phenomenon of slippage between the hand and the adjustment block, and improving the efficiency of the adjustment screw.

[0011] Secondly, the treadmill belt pressure testing mechanism provided in this application adopts the following technical solution:

[0012] A treadmill belt pressure detection mechanism is used to detect the tension of a treadmill as described above. It includes a mounting platform, a detection component for detecting the tension of the treadmill belt, a moving component, a spreading component, an adjusting component, and a display component. The detection component includes a detection plate, an air pressure bag, an air tube, an air bladder, and a pressure gauge. The detection plate is mounted on the mounting platform, and the air pressure bag is fixedly connected to the detection plate. The air tube includes a connecting portion and an extension portion. One end of the connecting portion is fixedly connected to the air pressure bag, and the other end of the connecting portion is fixedly connected to the extension portion. One end of the extension portion is fixedly connected to the air bladder, and the other end of the extension portion is fixedly connected to the pressure gauge. The moving component is mounted on the mounting platform to drive the detection component to move. The spreading component is mounted on the mounting platform to spread the treadmill belt and foot support frame. The adjusting component is mounted on the mounting platform to drive an adjusting screw to rotate. The display component is mounted on the mounting platform to display the information detected by the detection component.

[0013] By adopting the above technical solution, since treadmills are mass-produced in the factory, the tension of the running belt needs to be adjusted before shipment. This is usually done manually by staff, and it is impossible to know the specific tension of the running belt on each treadmill. The detection component is designed so that when the finished treadmill reaches the position near the detection component, the air bag is squeezed to bring the air pressure bag to the set value. Then, it is inserted between the running belt and the foot pedal support. The change in pressure gauge can specifically show the current tension. Staff can adjust the tension of the running belt on several treadmills to be consistent based on the air pressure gauge, thereby improving the overall product quality of the treadmills.

[0014] Optionally, the spreading assembly includes a first cylinder, a first clamping plate, a second clamping plate, and a fixing plate. The first cylinder is fixedly connected to the mounting platform. The first clamping plate and the piston rod of the first cylinder are fixedly connected. The side of the first clamping plate away from the mounting platform is fixedly connected to the fixing plate. The second clamping plate is hinged to the side of the fixing plate away from the first clamping plate. The side of the first fixing plate away from the first cylinder has a notch. One end of the second clamping plate is embedded in the notch. The first clamping plate and the second clamping plate are set at a certain angle. When the first clamping plate and the second clamping plate extend between the running belt and the tower plate support frame, the running belt squeezes the second clamping plate to rotate.

[0015] By adopting the above technical solution and setting the component to open up, when the finished treadmill reaches the position close to the detection component, the first cylinder pushes the first clamping plate and the second clamping plate to insert from the running belt and foot pedal bracket. As the first clamping plate and the second clamping plate go deeper, the force of the running belt toward the foot pedal bracket gradually pushes the hinged second clamping plate to rotate, thereby opening the running belt from the foot pedal bracket. This makes it easier for the detection plate and the air pressure bag to go into the space between the running belt and the foot pedal bracket for detection, further improving the efficiency of the detection component.

[0016] Optionally, the second clamping plate has a rotating groove on the side near the first clamping plate, and a second rotating shaft is rotatably connected to the two opposite inner sidewalls of the rotating groove. The second rotating shaft extends to the outside of the opposite sidewalls of the second clamping plate. Two mounting ears are fixedly connected to the side of the fixing plate away from the first clamping plate. The two mounting ears are respectively fitted onto the two ends of the second rotating shaft. A placement groove is formed on the side of the fixing plate away from the first clamping plate, penetrating the fixing plate near the mounting ears. A torsion spring is fitted on the second rotating shaft. The force-applying end of the torsion spring is fixedly connected to the bottom wall of the rotating groove, and the force-receiving end of the torsion spring is fixedly connected to the bottom wall of the placement groove.

[0017] By adopting the above technical solution, the torsion spring is set, and the second clamping plate is hinged to the fixed plate through the second rotating shaft. The force-applying end and the force-receiving end of the torsion spring are fixed to the second clamping plate and the fixed plate respectively, so that one end of the second clamping plate is close to the first clamping plate, thereby keeping one end of the first clamping plate and the second clamping plate in a close fit, which makes it easier to insert between the running belt and the foot pedal bracket, thus improving the efficiency of the opening component.

[0018] Optionally, the moving component includes a second cylinder, which is fixedly connected to the mounting platform and whose piston rod moves toward the running belt on the workstation. The piston rod of the second cylinder is fixedly connected to the detection plate.

[0019] By adopting the above technical solution and setting the moving component, when the piston rod of the second cylinder moves, it synchronously drives the detection plate to move between the running belt and the foot pedal bracket, thereby realizing the function of automatic insertion. After the test is completed, the second cylinder can drive the detection plate back to its original position, avoiding interference between the detection plate and the next treadmill to be tested on the conveyor belt, and improving the working efficiency of the testing component.

[0020] Optionally, the adjustment assembly includes a third cylinder, a rack, a gear, and an adjustment sleeve. The third cylinder is mounted on a mounting platform, and the piston rod of the third cylinder is fixedly connected to the rack. The gear is rotatably connected to the mounting platform and meshes with the rack to rotate along the circumference of the gear. The adjustment sleeve is fixedly connected to one side of the gear and is sleeved on the adjustment block.

[0021] By adopting the above technical solution and adjusting the component settings, when the adjusting sleeve is fitted onto the adjusting block, the third cylinder moves, thereby pulling the rack on the mounting platform to move. At the same time, the gear meshing on the rack rotates circumferentially, and the adjusting sleeve, which is coaxial with the gear, rotates circumferentially in sync, thereby driving the adjusting block on the adjusting screw to rotate. The number of rotations of the gear can accurately measure the number of rotations required for the adjusting screw, and automatic adjustment can be achieved without manual adjustment by the operator, thus improving the accuracy of the adjusting screw rotation.

[0022] Optionally, a cross slide module for driving the adjustment component to move is fixedly connected to the mounting platform, the third cylinder is fixedly connected to the slide of the cross slide module, and a motor for driving the slide of the cross slide module to move is fixedly connected to the cross slide module.

[0023] By adopting the above technical solution, the cross slide module is designed so that the adjustment components on the slide can move along the conveying direction of the running belt, thereby allowing the adjustment sleeve to be accurately fitted onto the adjustment block. After adjustment, the adjustment sleeve can be detached from the adjustment block for the next adjustment, thus improving the adjustment efficiency of the adjustment components.

[0024] Optionally, the adjusting sleeve has a limiting groove on the side away from the gear that matches the adjusting block. The limiting groove is polygonal, and the adjusting block is embedded in the limiting groove.

[0025] By adopting the above technical solution, the setting of the limiting groove on the adjusting sleeve allows the limiting groove to cooperate with the adjusting block on the adjusting rod, and both of them are polygonal. The polygonal setting can reduce the movement of the adjusting block in the limiting groove, avoid the phenomenon of the limiting block slipping, and improve the synchronization of the adjusting sleeve driving the adjusting block.

[0026] Optionally, the display component includes a PLC controller, which is fixedly connected to the mounting platform. The first cylinder is electrically connected to the PLC controller, the second cylinder is electrically connected to the PLC controller, the third cylinder is electrically connected to the PLC controller, and the motor is electrically connected to the PLC controller.

[0027] By adopting the above technical solution and configuring the PLC controller, the PLC controller can control the expansion component to first extend into the running belt and foot pedal bracket, and then the detection plate to extend into the space between the running belt and foot pedal. While detecting the tension, the PLC controller controls the movement of the first sliding component and the second sliding component. It can accurately move the first sliding component along the direction of movement of the running belt, and then control the second sliding component to move in a direction perpendicular to the direction of movement of the running belt, so that the adjusting sleeve is aligned with the adjusting block. Finally, the first sliding component is controlled to drive the adjusting sleeve to be fitted onto the adjusting block, thereby improving the automation of the entire testing component.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. The adjusting screw is rotatably connected to the foot pedal bracket. When the operator rotates the adjusting screw, the first rotating shaft threaded onto the adjusting screw moves back and forth in the direction of the running belt's movement, thereby driving the drive roller to move. This gradually tightens the running belt wound around the drive roller, thereby increasing the tension of the running belt and reducing slippage of the drive roller when the tension decreases, which would otherwise affect the user experience.

[0030] 2. The testing component is designed so that when the finished treadmill is transported to the testing component, the airbag is squeezed to bring the air pressure to the set value. Then, it is inserted between the running belt and the foot pedal support. The pressure gauge shows the current tension. Based on the pressure gauge, the staff can adjust the tension of the running belt on several treadmills to be consistent, thus improving the overall product quality of the treadmill.

[0031] 3. The design of the expansion component allows the first and second clamps to open the running belt from the foot pedal bracket, facilitating the insertion of the detection plate and air pressure bag between the running belt and the foot pedal bracket for detection, further improving the efficiency of the detection component.

[0039] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0040] This application discloses a treadmill and a treadmill belt pressure detection mechanism.

[0041] Example 1

[0042] Reference Figure 1 and Figure 2 A treadmill includes a treadmill body 1 and an adjusting screw 12. The adjusting screw 12 is mounted on the treadmill body 1 and can adjust the tension of the treadmill body 1.

[0043] Reference Figure 1 and Figure 2The treadmill body 1 includes a foot support frame 13, drive rollers 14, and a running belt 11. There are two drive rollers 14, each rotatably connected to one end of the foot support frame 13. The running belt 11 is wound around the two drive rollers 14 and the foot support frame 13. When the drive rollers 14 rotate, they drive the treadmill to rotate. Adjusting screws 12 are arranged along the arrangement direction of the two drive rollers 14 and rotatably connected to two opposite inner sidewalls of the foot support frame 13. One drive roller 14 has a first rotating shaft 141 rotatably connected to both ends, and these first rotating shafts 141 are threaded onto the adjusting screws 12. The adjusting screws 12 are used to adjust the distance between the two drive rollers 14. When the adjusting screw 12 rotates, the first rotating shaft 141 drives the drive roller 14 to move along the length direction of the adjusting screw 12, so as to change the distance between the two drive rollers 14, thereby adjusting the tension of the running belt 11 on the drive roller 14.

[0044] Reference Figure 2 and Figure 3 An adjusting block 121 is fixedly connected to one end of the adjusting screw 12. The adjusting block 121 can be polygonal, thus facilitating the rotation of the adjusting screw 12 by the operator. In this embodiment, the cross-section of the adjusting block 121 is a prismatic prism. In this embodiment, there are two adjusting screws 12, each corresponding to one end of one of the rotating rollers 14. Adjusting both adjusting screws 12 simultaneously yields better results.

[0045] The implementation principle of Example 1 is as follows: When the operator needs to adjust the tension of the running belt 11 on the treadmill, he / she holds and rotates the adjustment block 121, so that the drive roller 14 with the adjustment screw 12 is closer to or further away from the other drive roller 14, thereby adjusting the tension of the running belt 11.

[0046] Example 2

[0047] Reference Figure 1 and Figure 2 A treadmill belt pressure detection mechanism includes a testing component 2 and a mounting platform 21. The testing component 2 is mounted on the mounting platform 21, and the treadmill body 1 is located on one side of the testing component 2, enabling tension detection of the treadmill. In this embodiment, there are two sets of testing components 2 and mounting platforms 21, each located on opposite sides of the treadmill body 1. This application only describes one set as an example; the other set is installed on the other side of the treadmill body 1 according to actual conditions, and will not be described in detail here.

[0048] Combination Figure 3 and Figure 4The testing component 2 includes a detection component 22, a moving component 23, a spreading component 24, an adjusting component 25, and a display component 26. The mounting platform 21 is fixedly connected to the ground and located on one side of the treadmill body 1, providing a mounting platform for each component. The detection component 22 includes a detection plate 221, an air pressure bag 222, an air tube 223, an air bladder 224, and a pressure gauge 225, used to detect the tension of the running belt 11 on the treadmill. The detection plate 221 is placed on the mounting platform 21, and the air pressure bag 222 is fixedly connected to the side of the detection plate 221 away from the mounting platform 21. The trachea 223 includes a connecting part 2231 and an extension part 2232. One end of the connecting part 2231 is fixedly connected to the air pressure bag 222, and the other end of the connecting part 2231 is fixedly connected to the extension part 2232. The end of the connecting part 2231 near the extension part 2232 is located in the middle of the extension part 2232. One end of the extension part 2232 is fixedly connected to the air bladder 224, and the other end of the extension part 2232 is fixedly connected to the pressure gauge 225. When the air bladder 224 is squeezed, gas enters the air pressure bag 222 through the trachea 223, thereby enabling the air pressure bag 222 to maintain a certain value.

[0049] Combination Figure 4 When the detection plate 221 and the air pressure bag 222 are located between the running belt 11 and the foot support frame 13, the pressure gauge 225 can display the change value of the air pressure bag 222 under the pressure of the running belt 11. In this embodiment, a lifting cylinder 211 is fixedly connected to the mounting platform 21, and a compression plate 2111 is fixedly connected to the piston rod of the lifting cylinder 211. A placement platform 212 is fixedly connected to the mounting platform 21, and the air bag 224 is located in the placement platform 212. The side of the compression plate 2111 away from the lifting cylinder 211 abuts against the air bag 224, so that when the lifting cylinder 211 works, the compression plate 2111 can automatically compress the air bag 224.

[0050] Combination Figure 4 The moving component 23 includes a second cylinder 231, which drives the movement of the entire detection component 22 on the mounting platform 21. The second cylinder 231 is fixedly connected to the mounting platform 21, and the piston rod of the second cylinder 231 is fixedly connected to the side of the detection plate 221 away from the running belt 11. The movement direction of the piston rod of the second cylinder 231 and the running belt 11 is perpendicular to each other, so that when the piston rod of the second cylinder 231 moves, it synchronously pushes the detection plate 221 and the air pressure bag 222 toward the running belt 11, thereby automatically inserting the detection plate 221 and the air pressure bag 222 between the running belt 11 and the foot support frame 13.

[0051] Reference Figure 4 and Figure 5The spreading assembly 24 includes a first cylinder 241, a first clamping plate 242, a second clamping plate 243, and a fixing plate 244, thereby spreading the running belt 11 and the foot support frame 13 one step ahead of the detection assembly 22. The first cylinder 241 is fixedly connected to the mounting platform 21, and the first clamping plate 242 is fixedly connected to the piston rod of the first cylinder 241. The piston rod of the first cylinder 241 pushes the first clamping plate 242 toward the running belt 11. A fixing plate 244 is fixedly connected to the side of the first clamping plate 242 away from the mounting platform 21. A rotating groove 2431 is provided on one side of the second clamping plate 243. A second rotating shaft 2432 is rotatably connected to the two opposite inner sidewalls of the rotating groove 2431. The second rotating shaft 2432 extends to the outside of the opposite sidewalls of the second clamping plate 243. Two mounting lugs 2441 are fixedly connected to the side of the fixing plate 244 away from the first clamping plate 242. The two mounting lugs 2441 are respectively fitted one-to-one at both ends of the second rotating shaft 2432 and located on the two opposite sides of the second clamping plate 243, so that the second clamping plate 243 is hinged to the fixing plate 244 through the second rotating shaft 2432. In this embodiment, the rotating groove 2431 is located on the side of the second clamping plate 243 closer to the fixing plate 244, and the width of the second clamping plate 243 is greater than the width of the first clamping plate 242.

[0052] Reference Figure 4 and Figure 5The fixed plate 244 has a placement groove 2442 on the side near the hinge. The placement groove 2442 passes through the side of the fixed plate 244 near the mounting lug 2441, so that when the second clamping plate 243 and the fixed plate 244 are kept horizontal, the side of the second clamping plate 243 near the fixed plate 244 can be embedded in the placement groove 2442. The first clamping plate 242 has a notch 2421 on the side away from the first cylinder 241. When the first clamping plate 242 and the second clamping plate 243 need to be inserted between the running belt 11 and the foot support frame 13, the end of the second clamping plate 243 away from the hinge is embedded in the notch 2421. The first clamping plate 242 and the second clamping plate 243 are set at a certain angle. The side of the second clamping plate 243 away from the first clamping plate 242 has a guide surface 2433, so that the contact point between the first clamping plate 242 and the second clamping plate 243 is relatively flat, thereby facilitating the insertion of the first clamping plate 242 and the second clamping plate 243 into the running belt 11 and the foot support frame 13. When the first cylinder 241 pushes the first clamping plate 242 and the second clamping plate 243 into the running belt 11 and the foot support frame 13, the side of the running belt 11 closest to the foot support frame 13 presses against the second clamping plate 243. This causes the second clamping plate 243 to rotate and separate from the first clamping plate 242 during its movement, thereby opening up the running belt 11 and the foot support frame 13. A torsion spring 24321 is fitted onto the second rotating shaft 2432. The force-applying end of the torsion spring 24321 is fixedly connected to the bottom wall of the rotating groove 2431, and the force-receiving end of the torsion spring 24321 is fixedly connected to the bottom wall of the placement groove 2442, thus giving the second clamping plate 243 a force that keeps it close to the first clamping plate 242.

[0053] Combination Figure 6 The adjusting assembly 25 includes a third cylinder 251, a rack 252, a gear 253, and an adjusting sleeve 254, thereby adjusting the rotation of the adjusting block 121. The third cylinder 251 is mounted on the mounting platform 21, and its piston rod is fixedly connected to the rack 252, allowing the third cylinder 251 to move the rack 252. A support frame 2511 is slidably connected to the mounting platform 21, and the gear 253 is fixedly connected to the support frame 2511, meshing with the rack 252 to allow the gear 253 to rotate circumferentially. The adjusting sleeve 254 is fixedly connected to the side of the gear 253 away from the support frame 2511, and is fitted onto the adjusting block 121. The rotation of the gear 253 causes the adjusting sleeve 254 to rotate circumferentially synchronously. A limiting groove 2541 is provided on the side of the adjusting sleeve 254 away from the gear 253. In this embodiment, the limiting groove 2541 is hexagonal so as to match the adjusting block 121.

[0054] Reference Figure 6A cross slide module 213 is fixedly connected to the mounting platform 21, thereby driving the adjustment component 25 to move. A third cylinder 251 is fixedly connected to the slide of the cross slide module 213, and a support frame 2511 is fixedly connected to the slide of the cross slide module 213. A motor 2131 is fixedly connected to the cross slide module 213, thereby driving the slide of the cross slide module 213 to move the third cylinder 251 synchronously.

[0055] Reference Figure 1 The display component 26 includes a PLC controller 261 and a display screen 262. The PLC controller 261 is fixedly connected to the mounting platform 21. The first cylinder 241, the second cylinder 231, the third cylinder 251, and the lifting cylinder 211 are all electrically connected to the PLC controller 261. The motor 2131 on the cross slide module 213 is also electrically connected to the PLC controller 261, thus enabling automatic opening and movement of each component. The display screen 262 is fixedly connected to and electrically connected to the PLC controller 261 to display detection information.

[0056] The implementation principle of Example 2 is as follows: Two running belt pressure detection mechanisms can be used, placed on both sides of the treadmill body 1 respectively, to adjust the two adjusting screws 12 respectively. Taking one of the running belt pressure detection mechanisms as an example, after the test component 2 is powered on, the PLC controller 261 controls the first cylinder 241 to move closer to the direction of the running belt 11. Then, the first clamping plate 242 and the second clamping plate 243 extend between the running belt 11 and the foot support frame 13. At the same time, the second clamping plate 243 rotates and cooperates with the first clamping plate 242 to support the running belt 11. At this time, the PLC controller 261 controls the lifting cylinder 211 to work. The air bag 224 is squeezed multiple times, and the air pressure inside the air pressure bag 222 rises to the set value. The pressure gauge 225 displays the current air pressure value. Then, the PLC controller 261 controls the second cylinder 231 to move, inserting the detection plate 221 and the air pressure bag 222 between the running belt 11 and the foot support frame 13. Then, the change data displayed by the pressure gauge 225 is transmitted to the PLC controller 261. 1. The PLC controller 261 drives the third cylinder 25 to work. Then, the cross slide module 213 receives the instruction and moves along the direction perpendicular to the running belt 11, so that the adjusting sleeve 254 is aligned with the adjusting block 121. The cross slide module 213 then moves along the direction of the running belt 11, so that the adjusting sleeve 254 is fitted onto the adjusting block 121. Then, the third cylinder 251 works synchronously to drive the gear 253 and the adjusting sleeve 254 to rotate circumferentially, thereby adjusting the tension of the running belt 11. Then, the cross slide module 213 moves in the opposite direction of the direction of the running belt 11, and the adjusting sleeve 254 disengages from the adjusting block 121. The cross slide module 213 moves away from the running belt 11 along the direction perpendicular to the running belt 11, so that the adjusting component 25 slides back to the top of the mounting platform 21, and the test is completed.

[0057] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
