[0003] A search revealed an adjustable bicycle handlebar, publication number CN219687536U. The specification states that by using a movable positioning block, the position of the movable handlebar at both ends of the fixed handlebar can be adjusted by controlling the movement of the movable positioning block, thereby changing the length of the bicycle handlebar to meet the different needs of different users and provide a better user experience. The handlebar sliding groove and handlebar slide, along with the cooperation between the handlebar positioning groove and the handlebar positioning block, ensure the stability of the movable handlebar position.

[0004] However, in actual use, when the bicycle handlebars have not been adjusted for a long time, the inner wall of the gap at the extension will become clogged with dust and dirt or with slight oxidation and rust on the metal parts, making it difficult for them to move smoothly within the track. This requires a lot of effort to adjust the handlebars, which in turn affects the ease of use of the handlebars. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides an adjustable bicycle handlebar to solve the problem that in the prior art, after a long period of no adjustment, the extension of the bicycle handlebar will move unsmoothly within its movement track, thus requiring a large amount of force to adjust the handlebar, which in turn affects the ease of use of the handlebar.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an adjustable bicycle handlebar, including a mounting base and two handles. Extension rods are fixedly connected to both the left and right sides of the mounting base. A sponge ring is sleeved on the outside of each extension rod, and the sponge ring fits against the inner wall of a sliding groove. Limiting blocks are fixedly connected to both the front and rear sides of the extension rod. A sliding groove is formed inside the handles, and the extension rod is slidably connected inside the sliding groove. Limiting grooves are formed on both the front and rear sides of the inner wall of the sliding groove, and the limiting blocks are slidably connected inside the corresponding limiting grooves. Multiple locking slots are formed on both the upper and lower sides of the inner wall of the sliding groove, and locking blocks are engaged inside the locking slots, with the locking blocks slidably connected inside the extension rod.

[0023] To make the technical problems, technical solutions and advantages of this utility model clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0024] Example 1: Please refer to Figures 1 to 6 This utility model provides a technical solution: an adjustable bicycle handlebar, including a mounting base 1 and two handlebars 3. Extension rods 2 are fixedly connected to both the left and right sides of the mounting base 1. A sponge ring 14 is sleeved on the outside of the extension rod 2, and the sponge ring 14 fits against the inner wall of a sliding groove 4. The inside of the sponge ring 14 is moistened with lubricating oil, allowing lubricant to be applied to the connection between the extension rod 2 and the handlebars 3 during adjustment. Limiting blocks 6 are fixedly connected to both the front and rear sides of the extension rod 2. A sliding groove 4 is formed inside the handlebars 3, and the extension rod 2 is slidably connected to the sliding groove 4. Inside the slide 4, limit grooves 5 are provided on both the front and rear sides of the inner wall. Limiting blocks 6 are slidably connected inside the corresponding limit grooves 5. The limit grooves 5 limit the limit blocks 6, allowing the limit grooves 5 to rotate smoothly. With the cooperation of the limit grooves 5 and the limit blocks 6, the handle 3 will not deviate when moving. Multiple slots 7 are provided on both the upper and lower sides of the inner wall of the slide 4. The slots 7 are fitted with locking blocks 8. The locking blocks 8 are slidably connected inside the extension rod 2. The locking blocks 8 can limit the handle 3 and the extension rod 2, thereby making the adjusted position more stable.

[0025] When the handle 3 needs to be adjusted, the locking block 8 is slid inward to disengage from the slot 7 and slide into the extension rod 2. Then, the handle 3 is pulled to move outward. When the handle 3 is adjusted to the appropriate position, the locking block 8 is moved in the opposite direction to engage with the slot 7, thus limiting the handle 3. If the handle 3 cannot be moved easily, the locking block 8 is quickly slid into the slot 7 to strike the slot 7, causing the handle 3 to vibrate and dislodge dust from the slide groove 4, thus allowing the handle 3 to be pulled. During the movement, the handle 3 slides against the sponge ring 14, which applies lubricant to the inner wall of the slide groove 4, reducing the friction between the extension rod 2 and the handle 3, making the adjustment of the handle 3 more convenient.

[0026] Example 2: Based on Example 1, to achieve convenient movement of the locking block 8, two mounting slots 9 are provided inside the extension rod 2. The locking block 8 is slidably connected inside the mounting slots 9, which provide installation space for the locking block 8. Mounting pieces 10 are fixedly connected to the adjacent sides of the upper and lower locking blocks 8. The mounting pieces 10 are slidably connected inside the mounting slots 9, which limit the mounting pieces 10, preventing them from shifting during sliding. A pull rope 11 is fixedly connected to the end of the mounting piece 10 away from the locking block 8. One side of the pull rope 11 is slidably connected inside the mounting slots 9. The other side of 1 is slidably connected to the inside of the mounting base 1. The mounting groove 9 and the mounting base 1 limit the pull rope 11, allowing the pull rope 11 to slide smoothly. The other end of the pull rope 11 is fixedly connected to a rotating rod 13, allowing the rotating rod 13 to unwind one end of the pull rope 11. The rotating rod 13 is rotatably connected to the inside of the mounting base 1. The mounting base 1 limits the rotating rod 13, allowing the rotating rod 13 to rotate smoothly. An elastic element 12 is sleeved on the outside of the pull rope 11. One end of the elastic element 12 is fixedly connected to the inner wall of the mounting groove 9, and the other end of the elastic element 12 is fixedly connected to the mounting plate 10.

[0027] When the locking block 8 needs to be pulled, the rotating rod 13 is rotated so that one end of the pull rope 11 is wound around it, and the other end of the rotating rod 13 pulls the mounting plate 10 inward. As the mounting plate 10 deforms by squeezing the elastic element 12, it pulls the locking block 8 into the interior of the mounting groove 9. Conversely, when the rotating rod 13 is released, the elastic element 12 returns to its original position, and pushes the mounting plate 10 outward. The mounting plate 10 then pushes the locking block 8 outward, causing the mounting plate 10 to impact the inner wall of the mounting groove 9 and the locking block 8 to impact the inner wall of the groove 7. This shakes down the dust inside the slide 4. After the locking block 8 is stabilized, it engages with the interior of the groove 7, thus limiting the extension rod 2 and the handle 3.

[0028] Example 3: Based on Example 2, in order to facilitate the addition of lubricating oil to the sponge ring 14 and limit the rotation rod 13, two filling grooves 17 are opened inside both the rotation rod 13 and the extension rod 2. The filling grooves 17 are used to add lubricating oil to the sponge ring 14. Two blocking blocks 18 are hinged to the top of the rotation rod 13. The blocking blocks 18 are inserted into the filling grooves 17 at the corresponding positions, so that the blocking blocks 18 can block the oil inlet of the filling grooves 17 and limit the rotation rod 13. The blocking blocks 18 can serve multiple purposes. Storage grooves 15 are opened on the inner walls of the two filling grooves 17 on opposite sides. The storage grooves 15 are used to store the added lubricating oil. Multiple sponge columns 16 are fixedly connected to the inner wall of the storage grooves 15. The side of the sponge column 16 away from the inner wall of the storage groove 15 is in contact with the inner side of the sponge ring 14. The sponge column 16 can guide the lubricating oil inside the storage groove 15 into the interior of the sponge ring 14.

[0029] When lubricating oil needs to be added, the plug 18 is disengaged from the inside of the filling groove 17 by snapping it off, so that lubricating oil can be added into the storage groove 15 through the filling groove 17. After the filling is completed, the plug 18 is reset so that the plug 18 can block the filling groove 17, so that external dust cannot enter the inside of the filling groove 17 and the rotating rod 13 can be limited. At the same time, the lubricating oil inside the storage groove 15 can be absorbed by the sponge column 16 and enter the inside of the sponge ring 14, so that the sponge ring 14 can be moistened by the lubricating oil.

[0030] The working process of this utility model is as follows:

[0031] When the handle 3 needs adjustment, by engaging the plug 18, the plug 18 is disengaged from the filling groove 17, thus removing the plug 18 from limiting the rotating rod 13. This allows lubricating oil to be added to the storage groove 15 through the filling groove 17, absorbed by the sponge column 16, and entering the sponge ring 14, thus wetting the sponge ring 14. At this point, rotating the rotating rod 13 winds one end of the pull rope 11, causing the other end of the rotating rod 13 to pull the mounting plate 10 inward. As the mounting plate 10 deforms by compressing the elastic element 12, it pulls the locking block 8 into the mounting groove 9. Releasing the rotating rod 13 causes the elastic element 12 to reset, pushing the mounting plate 10 outward. This, in turn, pushes the locking block 8 outward, allowing the mounting plate 10 to... The impact of the lever 8 against the inner wall of the mounting groove 9 and the impact of the locking block 8 against the inner wall of the slot 7 dislodged the dust inside the slide 4. This action was repeated until the handle 3 and the extension rod 2 were loosened and could be pulled. Pulling the handle 3 allowed the sponge ring 14 to apply lubricant to the inner wall of the slide 4, reducing the friction between the extension rod 2 and the handle 3, thus allowing the handle 3 to be pulled smoothly. When the handle 3 was adjusted to the appropriate position and the locking block 8 remained stable, the locking block 8 engaged with the inside of the slot 7, thus limiting the extension rod 2 and the handle 3. After adjustment, the blocking block 18 was reset, thus blocking the filling groove 17, preventing external dust from entering the filling groove 17, and limiting the rotation rod 13. This made the handle 3 not only easy to adjust, but also highly stable after adjustment.
