Description

Technical Field

[0001] This utility model relates to the field of fitness equipment technology, specifically to an adjustable handlebar mechanism for a stationary bike. Background Technology

[0002] As people's living standards continue to improve, more and more people are paying attention to their physical fitness, and as a result, the number of people engaging in fitness activities is constantly expanding. Indoor exercise bikes with adjustable handlebars are fitness equipment designed for indoor use. Unlike ordinary bicycles, users don't move around as much when riding an indoor bike with adjustable handlebars, making them less restricted by location. They also effectively mimic outdoor cycling, leading to their rapid adoption and widespread popularity.

[0003] Traditional exercise bike handlebars are fixed to the frame lift bar with two sets of bolts. Loosening these bolts allows for adjustment of the handlebars' position to accommodate users of different sizes. However, spin bike handlebars usually have a display screen attached, which makes the handlebars heavier and shifts the center of gravity forward. Since adjusting the position requires unscrewing two sets of bolts, the heavy handlebars also require assistance to secure them after adjustment, making the process time-consuming, laborious, and cumbersome. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a simple and easy adjustment mechanism for the handrail of a stationary bicycle.

[0005] The technical solution of this utility model is to provide a motion bicycle handlebar adjustment mechanism with the following structure: including a frame lifting rod and a handlebar disposed on the frame lifting rod; the top of the frame lifting rod is connected to a horizontally extending slide rail, the bottom of the handlebar is connected to a slide block, and the slide block is movably connected to the slide rail; the slide block is connected to a guide component and a fixing component, the guide component is used to force the slide block to move along the extension direction of the slide rail, and the fixing component is used to lock the position of the slide block on the slide rail.

[0006] By adopting the above structure, the exercise bike handlebar adjustment mechanism of this utility model has the following advantages compared with the prior art:

[0007] This invention connects a guide component and a fixing component to the slide at the bottom of the handrail. When adjusting the position of the handrail, simply loosen the fixing component. Under the guidance of the guide component, the slide at the bottom of the handrail can only move along the extension direction of the slide rail, making the adjustment of the handrail position simpler and more stable. After the handrail is adjusted to the correct position, tighten the fixing component again. The whole operation process is easy and simple, requiring no assistance from others.

[0008] Preferably, the two side walls of the slide are bent downward to form folded plates, and the two folded plates and the slide form a groove with the opening facing downward; the slide rail is set in a square tube shape and is adapted to the shape of the groove. The slide rail is engaged in the groove, which can make the connection between the slide and the slide rail more stable. The square tube-shaped slide rail can also play a role in circumferential positioning to prevent the handrail from shifting to the left or right.

[0009] Preferably, the slide rail is provided with a first guide groove that penetrates its two side walls and extends along its length. The guide assembly includes a guide rod that is slidably connected in the first guide groove, and both ends of the guide rod extend out of the first guide groove and are connected to two folding plates.

[0010] Preferably, the fixing assembly includes a locking connecting rod and a locking bolt. The locking connecting rod has a threaded hole for the locking bolt to be threaded into. The slide rail has a second guide groove that penetrates its two side walls and is parallel to the first guide groove. The two folded plates have a first through hole and a second through hole respectively at positions corresponding to the second guide groove. One end of the connecting rod has a radial limiting protrusion, and the other end passes through the first through hole and the second guide groove in sequence. The connecting end of the locking bolt passes through the second through hole and is threaded into the locking connecting rod in the second guide groove. By tightening the locking bolt, the distance between the locking connecting rod and the outer end face of the locking bolt can be reduced, thereby squeezing the two folded plates and pressing them tightly against both sides of the slide rail, thus achieving a fixing effect.

[0011] Preferably, the fixing component also includes a screw handle, which is detachably connected to the threaded head of the locking bolt. Since the fixing component is installed close to the bottom of the handrail, the rotation of the screw handle is restricted. Therefore, the locking bolt can be turned by hand first, and when it can no longer be turned, the screw handle can be locked onto the threaded head of the locking bolt to continue turning. If the screw handle encounters a restriction on the handrail position during the turning process, it can be removed from the locking bolt, the angle adjusted, and then locked onto the threaded head of the locking bolt to rotate until the slide block is locked onto the slide rail.

[0012] Preferably, bushings are fitted on both the guide rod and the locking connecting rod, and the bushings are circumferentially limited to the corresponding guide rod and locking connecting rod. The upper and lower ends of the outer peripheral wall of the bushing are provided with horizontal cut surfaces, which fit against the inner walls of the corresponding first guide groove and second guide groove, so as to circumferentially limit the guide rod, locking connecting rod and slide rail. In this way, when adjusting the position of the handrail, you only need to push the handrail flat, and there is no need to worry about the circumferential rotation of the handrail, making the operation simple and convenient.

[0013] Preferably, the handlebar is equipped with a control knob and a display screen. The control knob is used to adjust the magnetic resistance of the exercise bike, and the display screen is used to display exercise data.

[0014] Preferably, the slide rail is provided with a first elongated hole extending along its length, and the slide block is provided with a second elongated hole at a position corresponding to the first elongated hole. The first elongated hole and the second elongated hole are used for the wires of the control knob and the display screen to pass through. Attached Figure Description

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown;

[0025] This utility model discloses a motion bicycle handlebar adjustment mechanism: including a frame lifting rod 1 and a handlebar 2 disposed on the frame lifting rod 1; the top of the frame lifting rod 1 is connected to a horizontally extending slide rail 3, and the bottom of the handlebar 2 is connected to a slide seat 4, which is movably connected to the slide rail 3.

[0026] The slide block 4 is connected to a guide component 5 and a fixing component 6. The guide component 5 is used to force the slide block 4 to move along the extension direction of the slide rail 3, and the fixing component 6 is used to lock the position of the slide block 4 on the slide rail 3.

[0027] This invention connects a guide component 5 and a fixing component 6 to the slide base 4 at the bottom of the handrail 2. When adjusting the position of the handrail 2, it is only necessary to loosen the fixing component 6. Under the guidance of the guide component 5, the slide base 4 at the bottom of the handrail 2 can only move along the extension direction of the slide rail 3, making the position adjustment of the handrail 2 simpler and more stable. After the handrail 2 is adjusted into place, the fixing component 6 can be tightened again. The whole operation process is easy and simple, and no assistance is required.

[0028] like Figures 2-4 As shown, the two side walls of the slide 4 are bent downward to form folded plates 41. The two folded plates 41 and the slide 4 enclose a groove 42 with the opening facing downward. The slide rail 3 is set in a square tube shape and is adapted to the shape of the groove 42. The slide rail 3 is engaged in the groove 42, making the connection between the slide 4 and the slide rail 3 more stable. In addition, the square tube-shaped slide rail 3 can also play a role in circumferential positioning to prevent the handrail 2 from shifting left and right.

[0029] The slide rail 3 is provided with a first guide groove 31 that runs through its two side walls and extends along its length. The guide assembly 5 includes a guide rod 51, which is slidably connected in the first guide groove 31. Both ends of the guide rod 51 extend out of the first guide groove 31 and are connected to two folding plates 41.

[0030] For example Figure 3 and Figure 5As shown, the fixing component 6 includes a locking connecting rod 61 and a locking bolt 62. One end of the locking connecting rod 61 has a threaded hole for the locking bolt 62 to be threaded. The slide rail 3 has a second guide groove 32 that penetrates its two side walls and is parallel to the first guide groove 31. The two folding plates 41 have a first through hole and a second through hole 411 at positions corresponding to the second guide groove 32, respectively. One end of the connecting rod 61 has a radial limiting protrusion ring 611, and the other end passes through the first through hole and the second guide groove 32 in sequence. The connecting end of the locking bolt 62 passes through the second through hole 411 and is threadedly connected to the locking connecting rod 61 in the second guide groove 32. By tightening the locking bolt 62, the distance between the locking connecting rod 61 and the outer end face of the locking bolt 62 can be reduced, thereby squeezing the two folding plates 41 and pressing the two folding plates 41 tightly against both sides of the slide rail 3, thus achieving a fixing effect.

[0031] The fixing component 6 also includes a screw handle 63, which is detachably connected to the threaded head of the locking bolt 62. Since the fixing component 6 is installed close to the bottom of the handrail 2, the rotation of the screw handle 63 is restricted. Therefore, the locking bolt 62 can be turned by hand first. When it can no longer be turned, the screw handle 63 can be locked onto the threaded head of the locking bolt 62 and turned. If the screw handle 63 encounters a restriction on the position of the handrail 2 during the turning process, it can be removed from the locking bolt 62, the angle adjusted, and then locked onto the threaded head of the locking bolt 62 to rotate until the slide block 4 is locked onto the slide rail 3.

[0032] Preferably, bushings 7 are fitted on both the guide rod 51 and the locking connecting rod 61, and the bushings 7 are circumferentially limited to the corresponding guide rod 51 and locking connecting rod 61. The upper and lower ends of the outer peripheral wall of the bushing 7 are provided with horizontal cut surfaces 71, which fit against the inner walls of the corresponding first guide groove 31 and second guide groove 32, so as to circumferentially limit the guide rod 51, locking connecting rod 61 and slide rail 3. In this way, when adjusting the position of the handrail 2, it is only necessary to push the handrail 2 flat, without worrying that the handrail 2 will flip over due to the forward tilt of the center of gravity, making the operation simple and convenient.

[0033] For example Figures 1-3 As shown, the handlebar 2 is connected to a control knob 8 and a display screen 9. The control knob 8 is used to adjust the magnetic resistance of the exercise bike, and the display screen 9 is used to display exercise data. The slide rail 3 has a first elongated hole 33 extending along its length, and the slide block 4 has a second elongated hole 43 at a position corresponding to the first elongated hole 33. The first elongated hole 33 and the second elongated hole 43 are used for the wires of the control knob 8 and the display screen 9 to pass through.

[0034] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
