Description

Adjustment and positioning device for fitness equipment The present invention relates to a component of fitness equipment, and more particularly to an adjustment and positioning device of the fitness equipment. The positioning and adjustment structure of traditional fitness equipment primarily relies on a pull rod pulling a guide block with a guiding slope, which is coupled with a clamping block with a corresponding guided slope. The pull rod pulls the guide block, causing the guiding and guided slopes to move relative to each other, causing the clamping block to move, facilitating tightening, positioning, or loosening adjustments. However, this single-slope guide structure presents numerous technical limitations and practical issues: First, the single-bevel guide design often results in uneven stress distribution when the clamping block is subjected to force, making it prone to deflection. This deflection not only affects the stability of the overall structure but also increases friction between components, accelerating wear. In extreme cases, it can even cause seizure, rendering the adjustment mechanism completely inoperable. Secondly, in actual use, the magnitude and direction of force applied by users often vary, and this uncertainty exacerbates the instability of the single-bevel guide structure. Especially when making large adjustments, the clamping block may wobble or move erratically, affecting the adjustment accuracy and user experience. Furthermore, traditional single-bevel designs, over time, can easily wear out the bevel contact area due to stress concentration, gradually changing the original geometry and affecting the performance and life of the adjustment mechanism. This wear not only increases maintenance costs but can also compromise safety. The present invention provides an adjustment and positioning device for fitness equipment, the main purpose of which is to improve stability and avoid jamming or shaking. To achieve the aforementioned objectives, the present invention provides an adjustment and positioning device for fitness equipment, comprising: An adjustment component, a pressing component, and a resisting member, wherein the adjustment component includes: a first pressing block, a second pressing block, and a displacement block; The first clamping block has a first inner side with a first inclined surface, and the first clamping block has a first through hole; The second tightening block has a second inner side with a second inclined surface, and the second tightening block has a second through hole; The displacement block is disposed between the first clamping block and the second clamping block. The displacement block has a first side and a second side opposite to each other. The first side has a first corresponding inclined surface, and the second side has a second corresponding inclined surface. The first corresponding inclined surface and the first inclined surface face each other, and the second corresponding inclined surface and the second inclined surface face each other. The displacement block has a through hole. The pressing assembly includes: a main shaft and a pressing unit, the main shaft is inserted into the first through hole, the through hole and the second through hole, and the displacement block can move relative to the main shaft; The pressing unit is used to move the first pressing block and the second pressing block closer to or farther away from each other; The abutment member is adjacent to the displacement block, and the displacement block is used to tighten or loosen the abutment member; and When the first clamping block and the second clamping block approach each other, the displacement block abuts against the abutted piece; when the first clamping block and the second clamping block move away from each other, the displacement block releases the abutted piece. As can be seen from the foregoing, the adjustment and positioning device of the fitness equipment of the present invention is mainly achieved by making the first tightening block have the first inclined surface, the second tightening block have the second inclined surface, and the displacement block have the first corresponding inclined surface and the second corresponding inclined surface. The first corresponding inclined surface and the first inclined surface face each other, and the second corresponding inclined surface and the second inclined surface face each other. The first tightening block and the second tightening block are moved closer to or farther away from each other through the pressing unit. When the first tightening block and the second tightening block are moved closer to each other, the displacement block is pressed against the abutted member to achieve the positioning effect. When the first tightening block and the second tightening block are moved away from each other, the displacement block releases the abutted member to achieve the adjustable effect. Since the displacement block has the first corresponding inclined surface and the second corresponding inclined surface, the first corresponding inclined surface and the first inclined surface face each other, and the second corresponding inclined surface and the second inclined surface face each other, therefore, when the first clamping block and the second clamping block compress the displacement block, it can have higher stability to enhance the stability of the adjustment component and effectively avoid jamming or shaking. The present invention provides an adjustment and positioning device for fitness equipment, which is used with a movable part A and a fixed part B of the fitness equipment, as shown in Figures 1 to 8, including: An adjustment assembly 10, a pressing assembly 20, and an abutting member 30. The adjustment assembly 10 includes a first pressing block 11, a second pressing block 12, and a displacement block 13. The adjustment assembly 10 is configured to move synchronously with the movable portion A, such as synchronous displacement or synchronous rotation. The adjustment assembly 10 is configured to move relative to the fixed portion B. The first clamping block 11 has a first inner side 11A and a first outer side 11B opposite to each other along an axial direction X. The first inner side 11A has a first inclined surface 111. The first clamping block 11 has a first through hole 11C extending along the axial direction X. The second clamping block 12 has a second inner side 12A and a second outer side 12B opposite to each other along the axial direction X. The second inner side 12A has a second inclined surface 121. The second clamping block 12 has a second through hole 12C extending along the axial direction X. The displacement block 13 is disposed between the first clamping block 11 and the second clamping block 12, so that the first clamping block 11, the displacement block 13 and the second clamping block 12 are arranged along the axial direction X. The displacement block 13 has a first side 13A and a second side 13B opposite to each other along the axial direction X. The first side 13A has a first corresponding inclined surface 131, and the second side 13B has a second corresponding inclined surface 132. The first corresponding inclined surface 131 faces and abuts against the first inclined surface 111, and the first corresponding inclined surface 131 and the first inclined surface 111 are complementary inclined surfaces. The second corresponding inclined surface 132 faces and abuts against the second inclined surface 121, and the second corresponding inclined surface 132 and the second inclined surface 121 are complementary inclined surfaces. The displacement block 13 has a through hole 13C extending along the axial direction X. The through hole 13C has an aperture D1. The pressing assembly 20 includes a main shaft 21 and a pressing unit 22. The main shaft 21 extends along the axial direction X and passes through the first through-hole 11C, the through-hole 13C, and the second through-hole 12C. A diameter D2 of the main shaft 21 is smaller than the diameter D1 of the through-hole 13C, so that the displacement block 13 can move relative to the main shaft 21. The pressing unit 22 is disposed on the main shaft 21. The pressing unit 22 is used to move the first pressing block 11 and the second pressing block 12 toward or away from each other along the axial direction X, so that the positioning device can switch between the adjustable state and the positioning state. In this embodiment, the pressing unit 22 can be integrally formed with the main shaft 21 or detachably connected. The abutment 30 is adjacent to the displacement block 13. In this embodiment, the abutment 30 is sleeved outside the displacement block 13. When the first clamping block 11 and the second clamping block 12 approach each other along the axial direction X, the displacement block 13 is pressed to move and abut against the abutment 30. At this time, the positioning device is in a positioning state, so that the movable part A will not be displaced relative to the fixed part B. When the first clamping block 11 and the second clamping block 12 move away from each other along the axial direction X, the displacement block 13 is loosened so that the displacement block 13 does not abut against the abutment 30. At this time, the positioning device is in an adjustable state, so that the movable part A can be displaced relative to the fixed part B. In the first embodiment of the present invention, referring to Figures 2 to 4 , the movable portion A is a movable housing 41 of a fitness equipment 40 . A seat 42 of the fitness equipment 40 is mounted on the movable housing 41 . The movable housing 41 is movable along the axial direction X. The fixing portion B is a seat tube 43 of the fitness equipment 40; The abutment member 30 is an outer sleeve 31 connected to one end of the seat tube 43. The outer sleeve 31 is a hollow cylindrical body having a through hole 311. The outer sleeve 31 is sleeved over the first clamping block 11, the second clamping block 12, and the displacement block 13. The first clamping block 11, the second clamping block 12, and the displacement block 13 are inserted into the through hole 311. The main shaft 21 has a first end 21A and a second end 21B opposite to each other. The main shaft 21 further has a threaded section 211. The threaded section 211 is closer to the second end 21B and farther from the first end 21A. The movable housing 41 is coupled to the second end 21B so that the movable housing 41 can move along the axial direction X with the main shaft 21. The pressing unit 22 includes a cam puller 221 and a first nut 222. The cam puller 221 is pivotally mounted on the first end 21A. The first nut 222 is threadedly engaged with the threaded segment 211. The first nut 222 abuts against the second tightening block 12. The second end 21B is coupled to the movable housing 41. The cam puller 221 has a connecting puller portion 221A and a cam portion 221B. The puller portion 221A is configured to be actuated by a user, and the cam portion 221B is configured to abut or release the first tightening block 11. 3 , when the user pulls the pull portion 221A, the cam portion 221B abuts against the first clamping block 11, causing the first clamping block 11 to move toward the second clamping block 12 . At this time, the main shaft 21 is simultaneously driven to move along the axial direction X, causing the first nut 222 to push the second clamping block 12 toward the first clamping block 11 , thereby forcing the displacement block 13 to move and abut against the inner wall of the outer sleeve 31 , preventing the adjustment assembly 10 from moving along the axial direction X. Furthermore, since the cam portion 221B abuts against the first clamping block 11 , the main shaft 21 also cannot move along the axial direction X, thereby positioning the movable housing 41 coupled to the main shaft 21. At this time, the positioning device is in a positioned state. 4 , when the user pulls the pull portion 221A in the opposite direction, the cam portion 221B is released and does not abut against the first clamping block 11 , so that the first clamping block 11 , the second clamping block 12 and the displacement block 13 are all in a loose state and do not abut against the inner wall of the outer sleeve 31 , so that the adjustment assembly 10 can move along the axial direction X. Moreover, since the cam portion 221B does not abut against the first clamping block 11 , the main shaft 21 can also move along the axial direction X, so that the movable housing 41 coupled to the main shaft 21 can also be displaced along the axial direction X. At this time, the positioning device is in an adjustable state. Preferably, referring to FIG. 2 , the first clamping block 11 and the second clamping block 12 are hexagonal columns, so that the adjustment component 10 together constitutes a hexagonal column, and the through hole 311 of the outer sleeve 31 is a hexagonal hole, thereby preventing the adjustment component 10 from rotating relative to the outer sleeve 31. In a second embodiment of the present invention, as shown in Figures 5 to 8, the movable portion A is the seat 42 of the fitness equipment 40, and the fixed portion B is the movable housing 41. The seat 42 can rotate relative to the movable housing 41 to adjust its angle. The seat 42 has two seat tubes 421, one of which is disposed between the first clamping block 11 and the displacement block 13, and the other of which is disposed between the second clamping block 12 and the displacement block 13. The abutment member 30 is an angle adjustment fixing seat 32 connected to the movable housing 41. The angle adjustment fixing seat 32 is a hollow seat body and has a through hole 321. The first clamping block 11 has a first insertion portion 112 and a first head portion 113 connected thereto, and the second clamping block 12 has a second insertion portion 122 and a second head portion 123 connected thereto. The angle adjustment fixing seat 32 is sleeved on the outside of the first insertion portion 112, the second insertion portion 122 and the displacement block 13. The first insertion portion 112, the second insertion portion 122 and the displacement block 13 are passed through the through hole 321, and the first head portion 113 and the second head portion 123 are located outside the angle adjustment fixing seat 32. The main shaft 21 is a bolt, and has a first end 21A and a second end 21B opposite to each other; The tightening unit 22 includes a bolt head 223 connected to the first end 21A and a second nut 224 screwed into the second end 21B. The bolt head 223 abuts against the first head 113, and the second nut 224 abuts against the second head 123. The first and second tightening blocks 11 and 12 are tightened or loosened by adjusting the second nut 224. Please refer to Figure 7. When the user locks the second nut 224, the second nut 224 presses against the second head 123, so that the first clamping block 11 and the second clamping block 12 approach each other, thereby forcing the displacement block 13 to move and press against the inner wall of the angle adjustment fixing seat 32, so that the adjustment component 10 cannot rotate relative to the angle adjustment fixing seat 32, and further the seat cushion tube 421 passing through the adjustment component 10 cannot rotate accordingly, so that the seat 42 cannot rotate relative to the movable shell 41 to adjust the angle. At this time, the positioning device is in a positioning state. Please refer to Figure 8. When the user loosens the second nut 224, the second nut 224 does not abut against the second head 123, so that the first tightening block 11, the second tightening block 12 and the displacement block 13 are all in a loose state and do not abut against the inner wall of the angle adjustment fixing seat 32. The adjustment component 10 can rotate relative to the angle adjustment fixing seat 32, allowing the seat 42 to rotate relative to the movable housing 41 to adjust the angle. At this time, the positioning device is in an adjustable state. As can be seen from the foregoing, the adjustment and positioning device of the fitness equipment of the present invention is mainly achieved by making the first tightening block 11 have the first inclined surface 111, the second tightening block 12 have the second inclined surface 121, and the displacement block 13 have the first corresponding inclined surface 131 and the second corresponding inclined surface 132. The first corresponding inclined surface 131 and the first inclined surface 111 face each other, and the second corresponding inclined surface 132 and the second inclined surface 121 face each other. The first tightening block 11 and the second tightening block 12 are moved closer to or farther away from each other through the pressing unit 22. When the first tightening block 11 and the second tightening block 12 are closer to each other, the displacement block 13 is pressed against the abutted member 30 to achieve the positioning effect. When the first tightening block 11 and the second tightening block 12 are moved away from each other, the displacement block 13 releases the abutted member 30 to achieve the adjustable effect. Since the displacement block 13 has the first corresponding inclined surface 131 and the second corresponding inclined surface 132, the first corresponding inclined surface 131 and the first inclined surface 111 face each other, and the second corresponding inclined surface 132 and the second inclined surface 121 face each other. Therefore, when the first clamping block 11 and the second clamping block 12 compress the displacement block 13, it can have higher stability, thereby improving the stability of the adjustment component 10 and effectively avoiding the occurrence of jamming or shaking. 10: Adjustment assembly 11: First tightening block 11A: First inner side 11B: First outer side 11C: First through hole 111: First inclined surface 112: First insertion portion 113: First head portion 12: Second tightening block 12A: Second inner side 12B: Second outer side 12C: Second through hole 121: Second inclined surface 122: Second insertion portion 123: Second head portion 13: Displacement block 131: First corresponding inclined surface 132: Second corresponding inclined surface 13A: First side 13B: Second side 13C: Through hole 20: Tightening assembly Component 21: Spindle 21A: First End 21B: Second End 211: Threaded Segment 22: Pressing Unit 221: Cam Puller 221A: Puller Portion 221B: Cam Portion 222: First Nut 223: Bolt Head 224: Second Nut 30: Abutment Component 31: Outer Component 311: Through Hole 32: Angle Adjustment Fixing Seat 321: Through Hole 40: Fitness Equipment 41: Moving Housing 42: Seat 421: Cushion Tube 43: Seat Tube A: Moving Portion B: Fixed Portion D1: Aperture D2: Diameter X: Axial Figure 1 is a perspective view of the adjustment and positioning device of the fitness equipment of the present invention.
