Technical Field

[0001] This utility model relates to the field of exercise bike technology, and in particular to an exercise bike with a novel adjustable handlebar. Background Technology

[0002] In the fitness equipment industry, the exercise bike, as a popular indoor exercise tool, provides users with a convenient and efficient way to exercise. With societal development, people have increasingly higher demands for exercise bikes, not only pursuing effective workouts but also hoping to enjoy recreational activities during exercise to relax both body and mind. Therefore, many users install racks on their exercise bikes to hold items such as phones and books, enhancing their user experience.

[0003] However, existing adjustable handlebar functions on exercise bikes have certain limitations. For example, Chinese utility model patent CN220938961U, entitled "A Handrail Support Structure for an Exercise Bike and an Exercise Bike," describes a structure including a handlebar adjustment tube connected at its bottom to the exercise bike and a handlebar adjustment welding fixing piece at its top; an electronic display mechanism located at the top of the handlebar adjustment tube, with handlebar mechanisms on both sides; a bracket fixing tube mechanism connected to the top of the electronic display mechanism, and a bracket mechanism movably connected to the top of the electronic display mechanism. The handlebar mechanism includes handlebar iron pipes located on both sides of the electronic display mechanism, with a handlebar fixing piece in the middle connected to the bracket fixing tube. The bracket fixing tube mechanism includes a fixing iron pipe, the bottom of which is connected to the top of the electronic display mechanism, and the top of which is connected to the bracket mechanism.

[0004] The aforementioned handrail mechanism is fixed to the handrail adjustment tube, but the handrail mechanism cannot be adjusted in the forward and backward direction. Users cannot personalize the position of the handrail according to their height, arm length, and exercise habits. This not only affects the user's comfort and stability during exercise, but may also lead to incorrect exercise posture and increase the risk of sports injuries. Utility Model Content

[0027] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0028] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0029] This embodiment mainly describes a stationary bike with a novel adjustable handlebar, as detailed below:

[0030] like Figures 1 to 6As shown, a novel adjustable handrail exercise bike includes a frame 1, a handrail frame 2, a lower slide seat 3, an upper slide seat 4, and a locking component 5. The upper slide seat 4 has a slide rail 41, and the lower slide seat 3 has a strip-shaped slider 31 that cooperates with the slide rail 41. Through the cooperation of the strip-shaped slider 31 and the slide rail 41, the upper slide seat 4 can slide relative to the lower slide seat 3. The strip-shaped slider 31 has an inverted T-shaped groove 32 in the middle. The locking component 5 includes a main sleeve 51, a secondary sleeve 52, a threaded rod 53, and a non-circular nut 54 fitted onto the threaded rod 53. The secondary sleeve 52 is located inside the main sleeve 51. The inner wall of the main sleeve 51 has a first toothed ring 511, and the outer wall of the secondary sleeve 52 has a second toothed ring 521 that cooperates with the first toothed ring 511. The secondary sleeve 52 has a channel 522 through which the threaded rod 53 passes, and a nut groove 524 that communicates with the channel 522 and cooperates with the non-circular nut 54. The lower end of the threaded rod 53 passes through the upper slide block 4 and extends into the inverted T-shaped slide groove 32. The lower end of the threaded rod 53 is provided with a limiting block 55 located in the inverted T-shaped slide groove 32. When the main sleeve 51 is rotated, the rotation of the main sleeve 51 drives the driven sleeve 52 to rotate, thereby causing the non-circular nut 54 to rotate. The rotation of the non-circular nut 54 drives the threaded rod 53 to move axially, so that the limiting block 55 abuts against the groove wall of the inverted T-shaped slide groove 32, pressing the lower slide block 3 onto the upper slide block 4. At this time, the lower slide block 3 and the upper slide block 4 are locked and cannot slide. When it is necessary to slide the handrail forward or backward, the main sleeve 51 is rotated in the opposite direction. The driven sleeve 52 moves in the opposite direction under the action of the main sleeve 51, and the non-circular nut 54 rotates in the opposite direction under the action of the driven sleeve 52, thereby causing the limiting block 55 to disengage from the groove wall of the inverted T-shaped slide groove 32. At this time, the lower slide block 3 and the upper slide block 4 are in the unlocked state, and the position of the handrail frame 2 can be adjusted by sliding the upper slide block 4 back and forth. This structural design allows the handrail 2 to be adjusted in the front and back directions on the slide rail 41 via the upper slide seat 4 and the lower slide seat 3, meeting the needs of different users, improving the user's comfort and stability during exercise, and reducing the risk of sports injuries.

[0031] like Figures 4 to 6 As shown, the main sleeve 51 has an upper opening at the top, and an outer cover 56 is provided at the upper opening. The outer cover 56 has an insertion part 561 that is inserted into the main sleeve 51. The design of the outer cover 56 can protect the internal structure of the main sleeve 51, prevent dust, debris and other objects from entering the interior of the main sleeve 51 and affecting the normal operation of the locking part 5, and also increase the overall aesthetics.

[0032] Specifically, to facilitate the installation, cleaning, and repair of the sleeve 52 and threaded rod 53, the outer cover 56 is detachably connected to the main sleeve 51. This detachable connection can be either a threaded connection or a snap-fit ​​connection. A support platform is provided on the upper outer wall of the sleeve 52. After the outer cover 56 is connected to the main sleeve 51, the bottom end of the insertion part 561 rests against the support platform to prevent the outer cover 56 from being completely pressed into the main sleeve 51 under external force. This detachable connection method allows for easy removal of the outer cover 56, improving maintenance convenience.

[0033] like Figure 4 As shown, the main sleeve 51 has an annular mounting cavity 512, and the slave sleeve 52 is located inside the annular mounting cavity 512. The first gear ring 511 is located on the inner wall of the annular mounting cavity 512, and the bottom of the annular mounting cavity 512 has a through hole 513 for the threaded rod 53 to pass through. This structural design allows the slave sleeve 52 to be stably installed inside the main sleeve 51. Through the cooperation of the first gear ring 511 and the second gear ring 521, the transmission between the main sleeve 51 and the slave sleeve 52 is realized, while providing a stable channel for the threaded rod 53 and ensuring the normal operation of the locking element 5.

[0034] Specifically, the nut groove 524 extends downwards from the bottom of the sleeve 52. The bottom of the annular mounting cavity 512 has a downwardly recessed annular groove 523. The through hole 513 is a circular hole coinciding with the center of the annular groove 523. An annular washer 6 is provided inside the annular groove 523. The annular washer 6 is fitted onto the threaded rod 53 and abuts against the lower surface of the non-circular nut 54. The annular washer 6 serves as a buffer and support, reducing direct contact between the non-circular nut 54 and the main sleeve 51, reducing wear, and improving the service life and reliability of the locking component 5. A second annular washer 8 is also fitted onto the threaded rod 53 between the upper slide block 4 and the main sleeve 51 to reduce direct contact between the main sleeve 51 and the upper slide block 4, thereby reducing wear on both the main sleeve 51 and the upper slide block 4.

[0035] like Figure 6 As shown, the outer wall of the main sleeve 51 has a handle 514. The handle 514 is designed to facilitate the user's operation of the main sleeve 51. The main sleeve 51 can be easily rotated through the handle 514 to lock and unlock the locking element 5, thereby conveniently adjusting the position of the handrail and improving ease of use.

[0036] Specifically, the width of the inverted T-shaped slide groove 32 is less than the minimum width of the limiting block 55. This design ensures that the limiting block 55 can slide stably within the inverted T-shaped slide groove 32 and reliably abut against the slide groove wall when locked, preventing the limiting block 55 from sliding out of the inverted T-shaped slide groove 32 and causing relative sliding between the lower slide seat 3 and the upper slide seat 4, thus ensuring the stability of the handrail after adjustment.

[0037] Specifically, the upper slide block 4 has cover plates 7 detachably connected to both ends by screws. Cover plates 7 have slide rail openings that communicate with the slide rail 41, and cover plates 7 also have sealing blocks 71 corresponding to the openings of the inverted T-shaped slide groove 32. The design of cover plates 7 protects the slide rail 41 and the inverted T-shaped slide groove 32, preventing dust, debris, etc., from entering the slide rail 41 and the slide groove, thus affecting the sliding effect. At the same time, the sealing blocks 71 can seal the openings of the inverted T-shaped slide groove 32, further improving the overall stability and reliability, and also facilitating the installation of the threaded rod 53 and the limiting block 55.

[0038] like Figure 4 and Figure 6 As shown, the upper slide block 4 has a slide bar 44 that extends into and slides along the inverted T-shaped groove 32. The width of the slide bar 44 is equal to the width of the opening of the inverted T-shaped groove 32. The slide bar 44 has a notch 43 that matches the width of the limiting block 55. The notch 43 has a connecting hole 42 that passes through the top of the upper slide block 4 for the threaded rod 53 to pass through. The length of the limiting block 55 is equal to the width of the bottom of the inverted T-shaped groove 32 and greater than the width of the slide bar 44. This structural design allows the slide bar 44 to slide stably within the inverted T-shaped groove 32. Through the notch 43 and the connecting hole 42, it cooperates with the threaded rod 53 and the limiting block 55 to achieve the pressing and releasing of the lower slide block 3, while ensuring that the limiting block 55 and the threaded rod 53 do not rotate. Only the non-circular nut 54 needs to be rotated.

[0039] Specifically, the non-circular nut 54 can be any non-circular shape. Since hexagonal nuts are a common type of nut, they have advantages such as simple structure, high strength, and easy processing and installation. They can meet the usage requirements of locking parts 5 and ensure the reliability of the locking effect. Generally, the non-circular nut 54 is designed as a hexagonal nut.

[0040] like Figure 4 As shown, the bottom of the inverted T-shaped slide groove 32 is provided with a concave strip-shaped guide groove 33. Both ends of the strip-shaped guide groove 33 are located between the two ends of the inverted T-shaped slide groove 32. The upper slide seat 4 is provided with a guide post 45 that extends into and cooperates with the strip-shaped guide groove 33. The guide post 45 can slide within the strip-shaped guide groove 33 to limit the sliding path of the upper slide seat 4. The design of the strip-shaped guide groove 33 and the guide post 45 can further limit the sliding path of the upper slide seat 4, ensuring a smoother and more precise sliding process, preventing the upper slide seat 4 from disengaging from the lower slide seat 3 during the sliding process, and improving the stability and reliability of the armrest adjustment.

[0041] In summary, the exercise bike with novel adjustable handrails of this invention, through the above structural design, achieves forward and backward adjustment of the handrails, which can meet the needs of different users, improve the user's comfort and stability during exercise, reduce the risk of sports injuries, and has high practical value and market prospects.
