Description

Technical Field

[0001] This disclosure relates to the field of strength testing technology, and in particular to a strength testing device for fitness training equipment. Background Technology

[0002] The strength testing of fitness equipment mainly focuses on several core indicators: static load, dynamic impact, fatigue durability, and material strength. Let me outline the specific methods: Static load testing involves continuously applying a specified force to the equipment to detect structural deformation and permanent deformation, such as the deformation of a treadmill frame under load. Dynamic impact testing uses an impact pendulum or drop hammer to simulate instantaneous impact and test impact resistance, such as the damage to dumbbells after free fall. Fatigue durability testing simulates long-term use by performing cyclic load tests, such as assessing the lifespan of a rowing machine after repeated pulling. Material strength testing involves performing mechanical tests on equipment components, such as compressive and tensile strength tests, such as the tensile strength of a barbell bar.

[0003] In existing technologies, strength testing of bar-type training equipment involves applying stable tension or pressure or using mechanical stress to test the strength characteristics of solid materials, which is in line with new material-related services. However, new material testing, metrology, related standardization, and certification services require consideration of the testing position height, necessitating adjustments to the device height. General strength testing requires clamping and fixing the equipment, and conventional workbenches are difficult to switch between clamping and fixing bar-type training equipment from the bottom and top, resulting in low applicability of the device. Summary of the Invention

[0009] Optionally, a shaft is provided at the bottom of the horizontal shaft corresponding to the position of the rotating rod, and the bottom of the shaft is rotatably mounted on the top of the base platform. A transmission belt is installed between the bottom of the shaft and the bottom of the rotating rod. A driven bevel gear is fixed at the top of the shaft, and a driving bevel gear is slidably engaged with the top of the driven bevel gear on the horizontal shaft. The driving bevel gear meshes with the driven bevel gear, and the driving bevel gear is rotatably mounted on the top of the shaft through a bearing seat.

[0010] Optionally, a pressure block is provided at the bottom of the other end of the horizontal plate, and the pressure block is located in the middle of the two clamping frames; wherein, a first electric push rod is fixed on the top of the horizontal plate at the pressure block, and the extended end of the first electric push rod is fixedly connected to the pressure block.

[0011] Optionally, the clamping assembly further includes: a vertical frame, a first bidirectional electric push rod, a connecting frame, and a telescopic plate. The top of both ends of the limiting frame is fixed with a vertical frame, and a first bidirectional electric push rod is provided between the vertical frames of the two limiting frames. The two extended ends of the first bidirectional electric push rod are fixedly connected to the two vertical frames.

[0012] Optionally, a long plate is slidably installed inside the side frame, with both ends of the long plate extending out from both ends of the side frame.

[0013] Optionally, the inner side of the clamping frame is provided with a clamping plate, and a plug rod is fixed between the clamping plate and the slider, and the plug rod slides through the clamping frame.

[0014] Optionally, a socket is fixed to one side of the movable base, the socket has an upward-facing opening, and a locking bolt is threaded onto the outer surface of the socket.

[0015] The technical solution provided in this disclosure may include the following beneficial effects: In this invention, after the rotating seat rotates the slide frame into a vertical position, the second motor drives the unidirectional screw to rotate, causing the screw plate to move along the inside of the slide frame. With the arc strip and the vertical block slidingly connected, the clamping component can move along the slide frame. Because the arc strip and the vertical block are connected, the slide frame will not interfere with the position of the clamping component when it rotates. At the same time, after the slide frame rotates, the clamping component can continue to move with the screw plate. This invention enables the shaft and rotating rod to rotate synchronously via a transmission belt. When the vertical frame is horizontal, the horizontal plate at the top of the rotating rod is located at the top of the side frame. The pressure block can be moved by the first electric push rod to press the middle part of the rod-shaped training equipment inside the clamping assembly. When the horizontal shaft drives the vertical frame to rotate vertically, the shaft and rotating rod rotate to the outside of the side frame under the drive of the transmission belt through the meshing of the active bevel gear and the driven bevel gear. After the pressure block and the first electric push rod are moved to the outside, the clamping assembly can be easily driven to move vertically by the rotating assembly without being interfered with by the position of the pressure block. In this invention, when performing strength testing on a single bar, clamping frames are held at both ends of the bar. A first electric push rod drives a pressure block to press against the middle of the bar. Simultaneously, a cylinder on the moving base drives the clamping assembly upwards from both ends, applying upward or downward pushing force to both ends of the bar, thereby testing the bar's bending degree. When the clamping assembly is adjusted to a certain height using a rotating component, the strength of fitness equipment such as a horizontal bar can be tested, simulating the pressure applied by a user's hand gripping area. Before testing, to facilitate the placement of the bar or similar equipment, a first bidirectional electric push rod moves two sets of side frames to the sides, separating or bringing the combined clamping frames closer together. This device is used to clamp, wrap, or separate and remove bar-type training equipment. When the clamping frame moves along the side frame surface through the limiting frame, the slider inside the side frame slides along the inside of the side frame and the surface of the long plate, keeping the clamping plate and the clamping frame in the same position. The setting of the connecting frame position can avoid being restricted by the vertical bars on both sides when installing equipment such as single bars. At the same time, when the rotating component moves the clamping component in the vertical direction, the telescopic plate can extend and retract in coordination to maintain the connection with the clamping component. The long plate is moved by the second bidirectional electric push rod, and then the insert rod on the surface of the slider of the same specification passes through the clamping frame to move the clamping plate. The thickness of the bar-type training equipment can be adjusted to maintain the stability of the clamping. The present invention allows the clamping frame to move along the moving groove of the base platform together with the moving seat by connecting the vertical block and the arc strip. This allows the position of the two clamping frames on the side frame to be adjusted, that is, the length of the rod-type training equipment can be adjusted, so that the clamping frame can be moved to both ends of the rod-type training equipment for clamping.

[0018] Embodiments of this disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are used only to explain this disclosure, and should not be construed as limiting this disclosure. Rather, embodiments of this disclosure include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0019] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 and Figure 8As shown in the figure, this disclosure proposes a fitness training equipment intensity testing device, including: a base 1, on which a movable groove 11 is provided, a rotating assembly 2 is provided on the top of the base 1 and is slidably installed inside the movable groove 11, and a clamping assembly 3 is installed on the upper end of the rotating assembly 2; the rotating assembly 2 includes a movable seat 21, there are two sets of movable seats 21, the bottom of the two sets of movable seats 21 are slidably installed inside the movable groove 11, a top plate 24 is provided on the top of the movable seat 21, a rotating seat 25 is fixedly installed on the top plate 24, a sliding frame 26 is rotatably installed inside the rotating seat 25, and a screw plate 29 is slidably installed inside the sliding frame 26; the clamping assembly 3 includes a side frame 31, there are two sets of side frames 31, two limiting frames 34 are symmetrically slidably sleeved on the outer surface of the two sets of side frames 31, and a slider 33 is slidably installed inside the side frame 31 corresponding to the position of the limiting frame 34, the limiting frame 34 facing towards A clamping frame 35 is fixed to one end of the inner side of the side frame 31. The clamping frames 35 inside the two limiting frames 34 are combined together. A semi-circular clamping groove is opened on the inner side of the clamping frame 35. A rotating rod 14 is rotatably installed on the top of the base platform 1 on the side away from the sliding frame 26. The rotating rod 14 is located in the middle of the side frame 31. A horizontal plate 15 is fixed to the top of the rotating rod 14. When using the device, the base platform 1 is fixed to the ground. This device is specially used for strength testing of bar-type training equipment. Here, bar-type training equipment is divided into single bars, such as horizontal bars used for weightlifting, or single bars, parallel bars, etc. During the test, the horizontal end of the bar-type training equipment needs to be installed on the base platform 1. The two ends of the bar-type training equipment are clamped by the clamping assembly 3 and pressure is applied to detect the critical point value of bending of the bar-type training equipment. This solution tests the strength characteristics of solid materials by applying stable tension or pressure or mechanical stress, which is in line with new material related services; new material testing, measurement, related standardization, certification and accreditation services.

[0020] like Figure 2 , Figure 3 and Figure 6As shown, in some embodiments, a bidirectional screw 12 is rotatably mounted inside the movable slot 11, and two movable seats 21 are threaded onto the surface of the bidirectional screw 12. A first motor 13 is fixed to one end of the base 1, and the output end of the first motor 13 is fixedly connected to the bidirectional screw 12. Two sets of cylinders 22 are fixed to the top of the movable seat 21, and the extended ends of the cylinders 22 are fixedly connected to the top plate 24. A third motor 212 is fixed to the outer end of the rotating seat 25 on one side of the base 1. The output end 12 is fixedly connected to one side of the rotating shaft of the rotating seat 25. A horizontal shaft 218 is fixed on the other side of the rotating shaft of the rotating seat 25, and the horizontal shaft 218 slides through the interior of the rotating shaft of the rotating seat 25 on the other side of the base 1. A convex strip 217 is symmetrically fixed on the surface of the horizontal shaft 218. The rotating shaft of the rotating seat 25 is slidably engaged with the convex strip 217. A socket 23 is fixed on one side of the movable seat 21. The socket 23 has an upward insertion port. A locking bolt 211 is threaded into the outer surface of the socket 23.

[0021] Understandably, the third motor 212 drives the rotating seat 25 to rotate. Under the action of the horizontal shaft 218, the sliding frame 26 can rotate with the rotating seat 25 to a vertical state. When the sliding frame 26 is in the horizontal direction, the clamping component 3 can perform strength testing on single-bar fitness equipment. After the sliding frame 26 rotates to a vertical state, the height of the clamping component 3 can be adjusted. For strength testing of fitness equipment such as horizontal bars, the first motor 13 drives the bidirectional screw 12 to rotate, moving the position of the seat 213. At the same time, the two sets of rotating seats 25 are slidably connected by a horizontal shaft 218, and the convex strip 217 on the horizontal shaft 218 keeps the inner shafts of the two rotating seats 25 locked, allowing them to rotate synchronously. The socket 23 can be used to insert the vertical bars at both ends of fitness equipment such as horizontal bars, and is fixed by the locking bolt 211 to maintain stability during testing.

[0022] like Figure 4 As shown, some output ends are fixedly connected to the one-way screw 27, and the screw plate 29 is threaded onto the surface of the one-way screw 27; wherein, an arc strip 210 is fixed on the outer surface of the screw plate 29, the center of the arc strip 210 is on the same straight line as the axis of the rotating seat 25, and a vertical block 38 is fixed at the bottom of the limiting frame 34, and the arc strip 210 slides through the vertical block 38.

[0023] Understandably, after the rotating seat 25 rotates the slide frame 26 into a vertical position, the second motor 28 drives the one-way screw 27 to rotate, causing the screw plate 29 to move along the inside of the slide frame 26. With the arc strip 210 and the vertical block 38 in sliding connection, the clamping component 3 can move along the slide frame 26 together. Because the arc strip 210 and the vertical block 38 are connected, the slide frame 26 will not interfere with the position of the clamping component 3 when it rotates. At the same time, after the slide frame 26 rotates, the clamping component 3 can continue to move along with the screw plate 29.

[0024] like Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, in some embodiments, a shaft 215 is provided at the bottom of the horizontal shaft 218 corresponding to the position of the rotating rod 14, and the bottom of the shaft 215 is rotatably mounted on the top of the base platform 1. A transmission belt 216 is installed between the bottom of the shaft 215 and the bottom of the rotating rod 14. A driven bevel gear 214 is fixed at the top of the shaft 215, and a driving bevel gear 213 is slidably engaged with the top of the driven bevel gear 214 on the horizontal shaft 218. The driving bevel gear 213 meshes with the driven bevel gear 214, and the driving bevel gear 213 is rotatably mounted on the top of the shaft 215 through a bearing seat. A pressure block 17 is provided at the bottom of the other end of the horizontal plate 15, and the pressure block 17 is located in the middle of the two clamping frames 35. A first electric push rod 16 is fixed at the top of the pressure block 17 on the horizontal plate 15, and the extended end of the first electric push rod 16 is fixedly connected to the pressure block 17.

[0025] It should be noted that, through the transmission of the transmission belt 216, the shaft 215 and the rotating rod 14 can rotate synchronously. When the vertical frame is in a horizontal state, the horizontal plate 15 at the top of the rotating rod 14 is located at the top of the side frame 31. The pressure block 17 can be moved by the first electric push rod 16 to squeeze the middle part of the rod-shaped training equipment inside the clamping assembly 3. When the horizontal shaft 218 drives the vertical frame to rotate into a vertical position, the active bevel gear 213 meshes with the driven bevel gear 214. Under the drive of the transmission belt 216, the horizontal plate 15 of the shaft 215 and the rotating rod 14 rotate to the outside of the side frame 31. After the position of the pressure block 17 and the first electric push rod 16 is transferred to the outside, the clamping assembly 3 can be easily driven to move in the vertical direction by the rotating assembly 2 without being interfered with by the position of the pressure block 17.

[0026] like Figure 4 , Figure 5 , Figure 7 and Figure 8As shown, in some embodiments, the clamping assembly 3 further includes: a vertical frame 39, a first bidirectional electric push rod 310, a connecting frame 311, and a telescopic plate 312. The tops of both ends of the limiting frame 34 are fixed with the vertical frame 39. The first bidirectional electric push rod 310 is disposed between the vertical frames 39 of the two limiting frames 34, and the two extended ends of the first bidirectional electric push rod 310 are fixedly connected to the two vertical frames 39. The outer surface of the first bidirectional electric push rod 310 is fixed with the connecting frame 311, and the other end of the connecting frame 311 is fixed with the telescopic plate 312. The bottom of the telescopic plate 312 is fixed to both sides of the base platform 1. A long plate 32 is slidably installed inside the side frame 31. The two ends of the long plate 32 protrude from the two ends of the side frame 31. The slider 33 is slidably sleeved on the surface of the long plate 32. A second bidirectional electric push rod 313 is provided between the two long plates 32 protruding from the two ends of the two sets of limiting frames 34, and the two extended ends of the second bidirectional electric push rod 313 are fixedly connected to the long plate 32. The second bidirectional electric push rod 313 is fixed on the outer surface of the connecting frame 311. A clamping plate 37 is provided on the inner side of the clamping frame 35. An insert rod 36 is fixed between the clamping plate 37 and the slider 33, and the insert rod 36 slides through the clamping frame 35.

[0027] It should be noted that the position of the clamping frame 35 is connected to the arc strip 210 via the vertical block 38, and can move along the moving groove 11 of the base platform 1 together with the moving seat 21, thereby adjusting the position of the two clamping frames 35 on the side frame 31, that is, adjusting the length of the bar-type training equipment, so that the clamping frames 35 can move to both ends of the bar-type training equipment for clamping. When performing strength testing on a single bar, the clamping frames 35 are clamped at both ends of the single bar, and the first electric push rod 16 drives the pressure block 17 to squeeze the middle position of the single bar. In conjunction with the cylinder 22 on the moving seat 21, the clamping assembly 3 is pushed upward from both ends, applying an upward or downward pushing force to both ends of the single bar, thereby testing the bending degree of the single bar. When the clamping assembly 3 is adjusted to a certain height with the help of the rotating assembly 2, the strength test of fitness equipment such as the horizontal bar can be performed after simulating the pressure applied by the user's hand grip. Before the test, in order to facilitate the placement of the single bar or similar equipment... The first bidirectional electric push rod 310 moves the two sets of side frames 31 to the sides, separating or bringing the combined clamping frame 35 closer together. This allows for clamping, wrapping, or removing the bar-type training equipment. When the clamping frame 35 moves along the surface of the side frame 31 via the limiting frame 34, the slider 33 inside the side frame 31 slides along the inside of the side frame 31 and the surface of the long plate 32, keeping the clamping plate 37 in the same position as the clamping frame 35. The position of the connecting frame 311 avoids being restricted by the vertical bars on both sides when installing equipment such as single-bar equipment. At the same time, when the rotating component 2 moves the clamping component 3 vertically, the telescopic plate 312 can extend and retract in coordination to maintain the connection with the clamping component 3. The second bidirectional electric push rod 313 drives the long plate 32 to move, and the insertion rod 36 on the surface of the slider 33 of the same specification passes through the clamping frame 35 to drive the clamping plate 37 to move, adjusting the thickness of the bar-type training equipment and maintaining the stability of the clamping.

[0028] Working principle: The base platform 1 is fixed to the ground. This device is specifically used for strength testing of bar-type training equipment. This equipment includes single bars, such as horizontal bars used in weightlifting, or horizontal and parallel bars. During testing, the horizontal end of the bar-type training equipment needs to be installed on the base platform 1. After the rotating seat 25 rotates the sliding frame 26 to a vertical position, the second motor 28 drives the one-way screw 27 to rotate, causing the screw plate 29 to move along the inside of the sliding frame 26. With the arc strip 210 and the vertical block 38 slidingly connected, the clamping assembly 3 can move along the sliding frame 26. Because the arc strip 210 and the vertical block 38 are connected, the sliding frame 26 will not interfere with the position of the clamping assembly 3 when rotating. Furthermore, after the sliding frame 26 rotates, the clamping assembly 3 can continue to move along with the screw plate 29. Driven by the drive belt 216, the shaft 215 and the rotating rod 14 can rotate synchronously. When the vertical frame is horizontal, the horizontal plate 15 at the top of the rotating rod 14 is located at the top of the side frame 31. The pressure block 17 can be moved by the first electric push rod 16 to press the middle part of the rod-shaped training equipment inside the clamping assembly 3. When the horizontal shaft 218 drives the vertical frame to rotate vertically, the active bevel gear 213 meshes with the driven bevel gear 214. Driven by the drive belt 216, the horizontal plate 15 rotates to the outside of the side frame 31. After the pressure block 17 and the first electric push rod 16 are moved to the outside, the clamping assembly 3 can be easily driven to move vertically by the rotating assembly 2 without being interfered with by the position of the pressure block 17. The position is connected to the vertical block 38 and the arc strip 210, and can move along the moving slot 11 of the base platform 1 together with the moving seat 21. This allows adjustment of the position of the two clamping frames 35 on the side frame 31, that is, adjustment of the length of the bar-type training equipment. This allows the clamping frames 35 to move to both ends of the bar-type training equipment for clamping. When performing strength testing on a single bar, the clamping frames 35 are clamped at both ends of the single bar, and the first electric push rod 16 drives the pressure block 17 to press the middle position of the single bar. In conjunction with the cylinder 22 on the moving seat 21, the clamping assembly 3 is pushed upward from both ends, applying an upward or downward pushing force to both ends of the single bar, thereby testing the bending degree of the single bar. When the clamping assembly 3 is adjusted to a certain height with the help of the rotating assembly 2, it can be used to test fitness equipment such as the horizontal bar. The strength test simulates the pressure applied by a user's hand gripping area. Before the test, to facilitate the placement of equipment such as single bars or horizontal bars, the first bidirectional electric push rod 310 moves the two sets of side frames 31 to the sides, separating or bringing the combined clamping frame 35 closer together. This allows for clamping, wrapping, or removing the bar-type training equipment. When the clamping frame 35 moves along the surface of the side frame 31 via the limiting frame 34, the slider 33 inside the side frame 31 slides along the inside of the side frame 31 and the surface of the long plate 32, keeping the clamping plate 37 and the clamping frame 35 in the same position. The position of the connecting frame 311 avoids being restricted by the vertical bars on both sides when installing equipment such as single bars. At the same time, when the rotating component 2 moves the clamping component 3 in the vertical direction, the telescopic plate 312 can extend and retract accordingly.Maintaining connection with the clamping assembly 3, the long plate 32 is moved via the second bidirectional electric push rod 313. This causes the insertion rod 36 on the surface of the slider 33 of the same specification to pass through the clamping frame 35, moving the clamping plate 37. This adjusts the thickness of the rod-type training equipment, maintains clamping stability, applies pressure, and detects the critical point value of bending of the rod-type training equipment.
