In order to achieve the foregoing objectives and effects, a quick replacement structure for the seat cushion of an exercise bike is provided, including: an adapter seat, including a rotating part and a supporting part, the rotating part is provided with a rotating hole, the supporting part is provided with a supporting hole, the aforementioned The axial direction of the rotating hole is different from the axial direction of the supporting hole, and the supporting hole is provided with a side cutout penetrating to the outer surface of the supporting part along its axial direction, and the supporting part is provided with a pair of lugs And are respectively located next to the side cut; a rotating unit, including a pair of support seats and a support shaft group, the pair of support seats each include a pillar part and an exposed part, the pair of support seats are respectively set through the pillar part Located in the two ends of the rotating hole, and the supporting shaft set penetrates the assembly of the pair of supporting seats in a locked state, so that the exposed parts of the pair of supporting seats are clamped against the opposite side surfaces of the rotating part. The exposed part of the support seat is provided with a bow-clamping groove for hooking a pair of seat bows of a cushion respectively; and a quick-release component, which can move through the pair of lugs and change the distance between the pair of lugs, The supporting hole jacket is positioned on a shaft section of an exercise bike.

Please refer to the first to fifth figures, the figure discloses a quick replacement structure 100 for the seat cushion of an exercise bike, including: an adapter seat 200, including a rotating part 210 and a supporting part 220, the rotating part 210 is provided with a rotating hole 211. The supporting portion 220 is provided with a supporting hole 221. The axial direction of the aforementioned rotating hole 211 is different from the axial direction of the supporting hole 221. A side cutout 222 on the outer surface of the part 220, the support part 220 is provided with a pair of lugs 223 and respectively located beside the side cutout 222; a rotating unit 300 includes a pair of support seats 310 and a support shaft set 320, the The pair of support seats 310 each include a through-pillar portion 311 and an exposed portion 312. The pair of support seats 310 are respectively set in two ends of the rotating hole 211 through the through-pillar portion 311, and the support shaft set 320 penetrates the assembly. When the support base 310 is locked, the exposed portions 312 of the pair of support bases 310 are clamped against the opposite side surfaces of the rotating part 210, and the exposed portions 312 of the pair of support bases 310 are provided with a bow-clamping groove 314 A pair of seat bows 410 for respectively hooking a cushion 400; and a quick-release assembly 500, which movably passes through the pair of lugs 223 and changes the distance between the pair of lugs 223, so that the supporting hole 221 clamps The sleeve is positioned on a shaft section 610 of an exercise bike 600.

Please refer to the sixth figure. After the above-mentioned structure provides the seat cushion 400 for personal preference, only the original seat cushion 400 on the exercise bike 600 is removed from the shaft section 610, and then the adapter 200 is installed. The supporting hole 221 is sleeved on the shaft section 610 of the exercise bike 600, and finally the supporting hole 221 of the adapter seat 200 is clamped on the shaft section 610 through the quick-release assembly 500, which can achieve quick and convenient replacement of the seat cushion 400. By taking the form of a seat cushion 400 that meets personal preferences (for example, the lower left side of the figure is a thick and thick seat cushion 400, and the upper right side of the figure is a race-type thinner seat 400), so as to achieve the purpose and utility of this creation.

The following is a detailed description of the detailed features of each component of this creation and their relationship with each other. Please refer to the first, second and seventh pictures for cooperation. The hole wall ring of the rotating hole 211 is provided with an internal tooth arc segment 212 (each internal tooth system of the internal tooth arc segment 212 is arranged along the axial direction of the rotating hole 211), and the outer peripheral surface of the column-piercing portion 311 of the pair of support seats 310 Each is provided with an outer tooth arc segment 313 meshing with the inner tooth arc segment 212 part. The supporting shaft set 320 includes a bolt 321 and a nut 322. The bolt 321 penetrates the exposed portion 312 and the post-piercing portion 311 of the pair of supporting seats 310 and cooperates with the nut 322 to press against one of the exposed portions of the supporting seat 310部312 Outer surface. By loosening the support shaft set 320, the pair of support seats 310 can be rotated relative to the rotation hole 211 through the column-piercing portion 311, thereby adjusting the tilt angle of the seat cushion 400 (as shown in the seventh figure, the solid line indicates the adjustment seat Before the angle of the cushion 400, and the dotted line indicates after the angle of the cushion 400 is adjusted), after the adjustment is completed, the support shaft set 320 is locked. Especially when the support shaft set 320 is locked with respect to the pair of support seats 310, the aforementioned outer tooth arc segment 313 is meshed with the inner tooth arc segment 212 to prevent the pair of support seats 310 from rotating when clamped against the rotating part 210. .

It is worth mentioning that the length of the inner tooth arc segment 212 is about half the circumference of the rotating hole 211, and the length of the outer tooth arc segment 313 is about half the circumference of the column penetrating portion 311, as in the first As shown in the second figure. Therefore, the rotation angle of the adjustable adapter 200 and the rotation unit 300 of the present invention is as large as 90 degrees. Therefore, the foregoing embodiment can be applied to the exercise bike 600 of the horizontal shaft section 610, and can also be rotated through the foregoing rotation. The range is applied to the exercise bike 600 of the longitudinal axle section 610 type, as shown in the eighth figure.

Please refer to Figures 1 to 3, the quick release assembly 500 includes a quick release screw 501, a washer 502, an inner solenoid 503, and a trigger 504. The quick release screw 501 is provided with the pair of lugs 223. A gasket 502 is inserted at one end to be screwed to the inner solenoid 503, and the inner solenoid 503 is sleeved by one end of the trigger 504, so that the trigger 504 sleeves the inner solenoid 503 and one end of the inner solenoid 503 is pressed against the pair One of the lugs 223. One of the pair of lugs 223 is provided with an inner concave arc surface 225, and the trigger 504 is provided with an outer convex arc surface 505 corresponding to the inner concave arc surface 225.

In addition, when the pair of supporting seats 310 are respectively set in the two ends of the rotating hole 211 with the through-pillar portions 311, the through-pillar portions 311 of the pair of supporting seats 310 do not contact each other. The supporting hole 221 is provided with a flash wall groove 226 along its axial direction and facing the direction of the rotating hole 211 for accommodating at least one screw 611 on the shaft section 610. The aforementioned shaft section 610 refers to a horizontal shaft section 610 type. Of 600 exercise bikes. The notches of the arch-clamping grooves 314 of the pair of supporting seats 310 are facing the direction of the adapter seat 200 and are restricted by the peripheral side of the adapter seat 200, so as to prevent the seat bows 410 from escaping from the notches.
