[0027] One end of the bottom cross bar 4 is welded with a mounting seat 9, and the top of the mounting seat 9 is provided with a groove, and a counterweight wheel 11 is installed in the groove through the rotation of the rotating shaft, and the two ends of the rotating shaft used to connect the breeding wheel 11 all protrude The pinion 10 is welded on the outside of the mounting base 9, the other end of the bottom cross bar 4 is welded with an inclined diagonal brace 23, and a reinforcing rib for improving the mechanical strength of the diagonal brace 23 is welded between the diagonal brace 23 and the bottom cross bar 4 , the middle part of the diagonal bracket 23 is rotatably equipped with a connecting shaft, the two ends of the connecting shaft are welded with a large gear 7 and the large gear 7 is symmetrically arranged with respect to the diagonal bracket 23, and the large gear 7 and the pinion 10 are connected by a rack 8 , the two ends of the connecting shaft for installing the large gear 7 are welded with a vertical connecting plate 6, and the ends of the connecting plate 6 are rotated and installed with a pedal 5 through a fixed pin, and the pedal 5 is symmetrical about the diagonal brace 23 Reversely set, thus constitute the pedal structure of the bicycle.
[0028] Adjusting rod 13 is threadedly connected on the diagonal brace 23, the bottom end of adjusting rod 13 faces the weight wheel 11 and is fixedly equipped with brake pads 12 by bolts, and the top end of adjusting rod 13 is welded with adjusting disc 16. When in use, The adjustment lever 13 is rotated by the adjustment disc 16, and the adjustment lever 13 interacts with the diagonal brace 23 to adjust the pressure between the brake pad 12 and the weight wheel 11, thereby adjusting the strength of the bodybuilder when using the exercise bike.
[0029] The top of the diagonal bracket 23 is fixed with a display screen 14 and a handle 15 by bolts. It should be noted that a pressure sensor is clamped and fixed between the brake pad 12 and the adjustment rod 13, and the built-in pressure sensor and the display screen 14 The processor is electrically connected, so that the pressure data between the brake pads 12 and the weight wheel 11 is intuitively displayed on the display screen 14, which is convenient for the user to adjust the weight of the weight wheel 11 more accurately.
[0030] Described adjusting device comprises the support frame 22 that is installed on the other end of bottom cross bar 4 and the adjustment cross bar 20 of horizontal installation, and the bottom end of described support frame 22 is welded on the other end of bottom cross bar 4, and the top of support frame 22 and One end of the horizontally installed adjusting cross bar 20 is fixedly connected, and the other end of the adjusting cross bar 20 is fixedly connected with the diagonal brace 23. The adjusting cross bar 23 is slidably equipped with a slide block 18, and the slide block 18 is slidably installed with a vertical adjustment The vertical bar 21 and the adjusting cross bar 23 are provided with a chute 19 for adjusting the vertical bar 21 to slide, and the seat 17 is fixed on the top of the adjusting vertical bar 21 by bolts.
[0031] see figure 2 One side of the slider 18 is welded with an adjustment frame 29, and a horizontal sliding plate 26 is slidably installed in the adjustment frame 29, and both ends of the sliding plate 26 extend out of the adjustment frame 29 and are integrally formed and fixed with a first block 25 The outer wall of the adjusting cross bar 20 is uniformly provided with a plurality of first draw-in slots 24 matching the first block 25, the middle part of the connecting plate 26 is connected with one end of the screw rod 28 in rotation, and the screw rod 28 is connected with the adjusting frame 29. The middle part is threaded and the other end of the screw mandrel 28 is stretched out and welded with a rotating disk 27 outside the adjustment frame 29 .
[0032]It should be noted that the screw rod 28 is rotated by the turntable 27, the screw rod 28 interacts with the adjustment frame 29 to adjust the position of the connecting plate 26, and the connecting plate 26 drives the first block 25 to be inserted into the slot 24, thereby The position of the slider 18 is fixed; compared with the traditional exercise bike that can only be adjusted in the height direction, this technical solution can adjust the front and rear positions of the seat during use, so as to better adapt to different usage habits The crowd effectively improves the practicability of the exercise bike.
[0033] see image 3 One end of the upper surface of the slider 18 is welded with a guide block 32, a horizontal second block 31 is installed on the guide block 32, and a plurality of horizontal blocks 31 are evenly provided on the side of the adjustment vertical bar 21 corresponding to the second block 31. The second clamping slot 30 matched with the second clamping block 31, one end of the second clamping block 31 is inserted into the second clamping block 31, thereby fixing the height of the vertical rod 21 for adjustment, the other end of the second clamping block 31 A draw ring 34 is welded, the side of the draw ring 34 is fixedly connected to one end of the spring 33 , and the other end of the spring 33 is fixedly connected to the side of the fixed block 32 .
[0034] It should be noted that when adjusting the height of the seat, the second block 31 is pulled out and separated from the adjustment vertical bar 21 through the pull ring 34, so that the vertical position of the adjustment vertical bar 21 can be adjusted. Compared with the traditional method of thread adjustment, the operation of this technical solution is obviously more convenient and quicker, which simplifies the operation steps of the user when adjusting, and is easy to use, and the adjustment vertical rod is fixed by the buckle, and the fixing effect is excellent. Well, there is no chance of the seat slipping off.
[0035] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or perform equivalent replacements for some of the technical features. Within the spirit and principles of the present invention, any modifications, equivalent replacements, improvements, etc., should be included within the protection scope of the present invention, and the content that is not described in detail in this specification belongs to those skilled in the art. existing technology.
