Description

Technical Field

[0001] This utility model relates to the field of sports technology, and in particular to a resistance adjustment device for exercise bikes. Background Technology

[0002] Exercise bikes are a common type of fitness equipment, allowing people to exercise without leaving home. A Chinese utility model patent, authorized publication number "CN222841477U", discloses an adjustable resistance magnetically controlled exercise bike, comprising: a rotating wheel at one end of the main body; an electric push rod, a positioning bracket, and a vertical plate on the base surface; a spring on the side of the vertical plate; a base at one end of the spring; and a damping plate on the surface of the base. The beneficial effect is that when using the exercise bike to simulate going uphill or downhill, the electric control can move the electric push rod up or down. When the electric push rod moves up, one end of the exercise bike body tilts around the positioning bracket, causing the rotating wheel at the other end of the exercise bike body to press down on the damping plate. As the electric push rod moves up, the contact between the rotating wheel and the damping plate increases, automatically increasing the damping effect of the exercise bike body. This is convenient for users as it eliminates the need for manual adjustment of the damping level.

[0003] The above technical solution uses electric control to move the electric push rod up or down. When the electric push rod moves up, one end of the exercise bike body can be tilted around the positioning bracket, and then the rotating wheel at the other end of the exercise bike body can be pressed down on the damping plate. As the electric push rod moves up, the contact between the rotating wheel and the damping plate increases, thereby automatically increasing the damping effect of the exercise bike body. This is convenient for users as it eliminates the need for manual adjustment of the damping size. However, the above technical solution still has certain drawbacks. For example, while the device can tilt one end of the exercise bike body around the positioning bracket by moving the electric push rod up, and then press down the damping plate on the rotating wheel at the other end of the exercise bike body, the damping mechanism requires maintenance and repair after long-term use. This requires workers to use special tools and multiple people to work together to disassemble and repair it. This operation is complicated and difficult, which increases the workload of workers and reduces the practicality and reliability of the equipment. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a resistance adjustment device for exercise bikes. This device can solve the problem that when the device moves upward by the electric push rod, one end of the exercise bike body can be tilted around the positioning bracket, and then the rotating wheel set at the other end of the exercise bike body can press down the damping plate. However, when the damping mechanism needs maintenance and repair after long-term use, it requires workers to use special tools and multiple people to work together to disassemble and repair it. This operation is complicated and difficult, which increases the workload of workers and reduces the practicality and reliability of the equipment.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a resistance adjustment device for an exercise bike, comprising a base, a hydraulic telescopic rod, an exercise bike body, and two support frames, wherein a limit component is provided on the base; The limiting component includes a vertical plate, a damping plate, and a mounting base. The mounting base is fixedly installed on the upper surface of the rear end of the base. A vertical plate slide groove is provided on the upper surface of the mounting base.

A first limiting block groove is provided on both inner walls of the vertical plate slide groove. A limiting block is slidably connected inside the two first limiting block grooves. A second limiting block groove is provided on both outer walls of the lower end of the vertical plate. The mounting base has rotating threaded rod sleeves rotatably connected to both sides, and rotating threaded rods are provided inside the two first limit block slots. A second fixing block is fixedly installed on the outer wall of the inclined surface on one side of the lower end of the upright plate. A second movable block is rotatably connected to the outer wall of the second fixing block away from the upright plate. A spring is fixedly installed on the outer wall of the second movable block away from the second fixing block.

[0006] Preferably, the damping plate is arc-shaped, the outer wall of the lower end of the vertical plate is slidably connected to the inside of the vertical plate slide groove, and the outer walls of the four T-shaped blocks at the lower end of the vertical plate are slidably connected to the inside of the four T-shaped block grooves on the inner wall of the vertical plate slide groove. Among them, the ends of the two limiting blocks near the second limiting block grooves both slide into the interior of the vertical plate groove and are respectively slidably connected to the interior of the corresponding second limiting block grooves.

[0007] Preferably, the ends of the two rotating threaded rods near the limiting block are respectively fixedly connected to the outer wall of the corresponding limiting block, and the ends of the two rotating threaded rod sleeves near the limiting block are both rotatably extended into the interior of the first limiting block groove; The ends of the two rotating threaded rods away from the limiting block are respectively connected to the internal threads of the corresponding rotating threaded rod sleeves, and the end of the spring away from the second movable block is fixedly connected to the arc-shaped outer wall of the damping plate.

[0008] Preferably, both support frames are fixedly installed on the upper surface of the base, and the two sides of the exercise bike body are rotatably connected to the upper end of the corresponding support frame via a pivot. The hydraulic telescopic rod is fixedly installed on the upper surface of the front end of the base.

[0009] Preferably, a first movable block is fixedly installed at the lower end of the inclined wall at the front end of the exercise bike body; The output end of the hydraulic telescopic rod is fixedly equipped with a first fixing block.

[0010] Preferably, the outer wall of the first fixed block away from the hydraulic telescopic rod is rotatably connected to the inner wall of the first movable block away from the inclined wall at the front end of the exercise bike body. The exercise bike has a rotating wheel installed at the rear of its main body, and the curved surface of the damping plate contacts the outer wall of the rotating wheel.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. The resistance adjustment device of this exercise bike uses rotating threaded sleeves on both sides of the mounting base in the limiting assembly to rotate the threaded rod sleeves. Rotating the threaded sleeves drives the rotating threaded rod connected to them to move in the first limiting block groove. Rotating the threaded rod pushes the limiting block to slide, so that the limiting block slides out of the second limiting block groove at the lower end of the upright plate, releasing the limitation on the upright plate. At this time, the lower end of the upright plate can slide along the upright plate slide groove on the mounting base, thereby removing the upright plate and the damping mechanism connected to it as a whole. This makes the disassembly of the damping mechanism simple and quick, avoiding the need for workers to use special tools to disassemble it, effectively reducing the workload of workers.

[0018] Please see Figure 1-4 This utility model provides a technical solution: a resistance adjustment device for exercise bikes, including a base 1, a hydraulic telescopic rod 2, an exercise bike body 5, and two support frames 12; A limit component is provided on the base 1; The limiting assembly includes a vertical plate 7, a damping plate 8, and a mounting base 13. The mounting base 13 is fixedly mounted on the upper surface of the rear end of the base 1. The damping plate 8 is arc-shaped. A vertical plate groove 15 is formed on the upper surface of the mounting base 13. The lower outer wall of the vertical plate 7 is slidably connected to the interior of the vertical plate groove 15. The outer wall of the connecting block on the damping plate 8 is rotatably connected to the interior of the upper end of the vertical plate 7. The outer walls of the four T-shaped blocks at the lower end of the vertical plate 7 are slidably connected to the interior of the four T-shaped block slots on the inner wall of the vertical plate groove 15. A first limiting block groove 17 is formed on both sides of the inner wall of the vertical plate groove 15. A limiting block 18 is slidably connected inside each of the two first limiting block grooves 17. A second limiting block groove 19 is formed on both sides of the lower outer wall of the vertical plate 7. The ends of the two limiting blocks 18 near the second limiting block grooves 19 are slidably extended into the interior of the vertical plate groove 15 and are slidably connected to the interior of the corresponding second limiting block grooves 19. Both sides of the mounting base 13 are rotatably connected to rotating threaded rod sleeves 14. Rotating threaded rods 16 are provided inside the two first limiting block slots 17. The ends of the two rotating threaded rods 16 near the limiting block 18 are respectively fixedly connected to the outer wall of the corresponding limiting block 18. The ends of the two rotating threaded rod sleeves 14 near the limiting block 18 are rotatably extended into the interior of the first limiting block slot 17. The ends of the two rotating threaded rods 16 away from the limiting block 18 are respectively threadedly connected to the interior of the corresponding rotating threaded rod sleeves 14. A second fixing block 11 is fixedly installed on the outer wall of the inclined surface on one side of the lower end of the upright plate 7. A second movable block 10 is rotatably connected to the outer wall of the second fixing block 11 away from the upright plate 7. A spring 9 is fixedly installed on the outer wall of the second movable block 10 away from the second fixing block 11. The end of the spring 9 away from the second movable block 10 is fixedly connected to the arc-shaped outer wall of the damping plate 8.

[0019] Two support frames 12 are fixedly installed on the upper surface of the base 1. The two sides of the exercise bike body 5 are rotatably connected to the upper end of the corresponding support frame 12 via a pivot. The hydraulic telescopic rod 2 is fixedly installed on the upper surface of the front end of the base 1. A first movable block 4 is fixedly installed at the lower end of the inclined wall at the front end of the exercise bike body 5. A first fixed block 3 is fixedly installed at the output end of the hydraulic telescopic rod 2. The outer wall of the first fixed block 3 away from the hydraulic telescopic rod 2 is rotatably connected to the inner wall of the first movable block 4 away from the inclined wall at the front end of the exercise bike body 5. A rotating wheel 6 is installed at the rear end of the exercise bike body 5. The arc-shaped surface of the damping plate 8 contacts the outer wall of the rotating wheel 6.

[0020] Furthermore, when using this device, the tilt angle of the exercise bike body 5 can first be adjusted by the hydraulic telescopic rod 2. The output end of the hydraulic telescopic rod 2 extends and retracts, driving the first fixed block 3, which is fixedly connected to it, to move. The first fixed block 3 is rotatably connected to the first movable block 4, thereby pushing or pulling the front end of the exercise bike body 5, causing the exercise bike body 5 to rotate around the pivot at the upper end of the two side support frames 12 to adapt to the riding posture needs of different users. At the same time, the rotating wheel 6 installed at the other end presses down on the damping plate 8. As the hydraulic telescopic rod 2 moves upward, the contact degree between the rotating wheel 6 and the damping plate 8 can be increased, thereby... The movement increases the damping effect of the exercise bike body 5. Then, when it is necessary to disassemble the damping mechanism, by rotating the rotating threaded rod sleeves 14 on both sides of the mounting base 13, the rotating threaded rod sleeves 14 drive the rotating threaded rod 16 connected to it to move in the first limiting block groove 17. The rotating threaded rod 16 pushes the limiting block 18 to slide, so that the limiting block 18 slides out from the second limiting block groove 19 at the lower end of the upright plate 7, releasing the limitation on the upright plate 7. At this time, the lower end of the upright plate 7 can slide along the upright plate sliding groove 15 on the mounting base 13, thereby removing the upright plate 7 and the damping mechanism such as the damping plate 8 connected to it as a whole.

[0021] By rotating the threaded sleeves 14 on both sides of the mounting base 13 in the limiting assembly, the threaded sleeves 14 drive the threaded rod 16 connected to them to move in the first limiting block groove 17. The threaded rod 16 pushes the limiting block 18 to slide, so that the limiting block 18 slides out from the second limiting block groove 19 at the lower end of the upright plate 7, releasing the limitation on the upright plate 7. At this time, the lower end of the upright plate 7 can slide along the upright plate slide groove 15 on the mounting base 13, thereby removing the upright plate 7 and the damping mechanism such as the damping plate 8 connected to it as a whole. This method of disassembling the damping mechanism is simple and quick, avoiding the need for workers to use special tools to disassemble it, and effectively reducing the workload of workers.
