Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example: Figure 1-3As shown, this utility model provides a bicycle handlebar locking mechanism, including a housing 1. An adjustment mechanism 3 is provided inside the housing 1. Locking mechanisms 2 are fixedly provided on both sides of the upper end of the adjustment mechanism 3 and on the lower end of the housing 1. The locking mechanism 2 includes a locking base 20. One side of the locking base 20 is fixedly connected to the adjustment mechanism 3. A locking ring 22 is fixedly provided on one side of the locking base 20. An opening 26 is provided on the outer side of the locking ring 22. Two locking plates 25 are fixedly provided on the outer side of the locking ring 22. A locking screw 28 is inserted into the inner side of the two locking plates 25. A locking nut 27 is threaded onto the outer side of the locking screw 28. When using the locking mechanism 2, firstly, the handlebars with anti-slip coating 2... The locking ring 22 is fitted onto the bicycle handlebars, ensuring that the locking ring 22 fits tightly against the surface of the handlebars. Then, the locking screw 28 is inserted between the two locking plates 25 through the locking hole 24 on the locking plate 25, and it slides into contact with the locking hole 24. Next, the locking nut 27 is threaded onto the outside of the locking screw 28, and the locking nut 27 is rotated until it presses tightly against the locking plate 25, thereby achieving a stable lock of the locking ring 22 onto the bicycle handlebars. Since the locking ring 22 is made of soft material and has an anti-slip coating 21 on its inner side, it can increase the friction between the locking ring and the handlebars, preventing the handlebars from sliding or rotating in the locked state, and ensuring the safety and stability of the lock.

[0018] The inner side of the locking ring 22 is coated with an anti-slip coating 21. The upper surface of the locking plate 25 is provided with a locking hole 24. The locking hole 24 slides and fits with the locking screw 28. The locking ring 22 is a soft ring. The locking ring 22 is made of soft material and is coated with an anti-slip coating 21 on the inner side, which can increase the friction between it and the handlebar. The locking screw 28 can slide on the inner side through the locking hole 24.

[0019] The adjustment mechanism 3 includes an adjustment rod 30 located inside the outer casing 1. Multiple equally spaced limiting grooves 31 are provided on both sides of the adjustment rod 30. Two symmetrically distributed limiting cylinders 33 are inserted into one side of the outer casing 1, and two limiting screws 36 are inserted into the side of the outer casing 1 away from the limiting cylinders 33. The limiting screws 36 are threadedly engaged with the limiting cylinders 33. During the use of the adjustment mechanism 3, the adjustment rod 30 is first inserted into the inner side of the outer casing 1 through the adjustment groove 32 at the upper end of the outer casing 1, ensuring that the adjustment rod 30 can slide freely within the adjustment groove 32. Then, according to the actual position and size of the bicycle handlebars, the position of the adjustment rod 30 is adjusted so that the limiting grooves 31 on both sides are aligned with the outer casing. The limiting hole 34 on the shell 1 corresponds to the inserted limiting cylinder 33. Then, the limiting cylinder 33 is inserted into the limiting hole 34 from one side of the shell 1, ensuring that the limiting cylinder 33 can slide freely in the limiting hole 34. At this time, by rotating the limiting screw 36, it is threadedly engaged with the limiting cylinder 33 and gradually tightened until the limiting screw 36 presses against the limiting groove 31 of the adjusting rod 30, thereby fixing the position of the adjusting rod 30. To prevent the limiting screw 36 from loosening, an anti-loosening washer 35 can be fitted on its outer side. By adjusting the adjusting mechanism 3, the position and angle of the locking mechanism 2 can be easily adjusted to adapt to bicycle handlebars of different sizes and shapes, ensuring the accuracy and stability of locking.

[0020] An adjustment groove 32 is provided at the upper end of the outer shell 1. The adjustment groove 32 is slidably fitted with the adjustment rod 30. Two symmetrically distributed limiting holes 34 are provided on one side of the outer shell 1. The limiting holes 34 are slidably fitted with the limiting cylinder 33. An anti-loosening washer 35 is sleeved on the outside of the limiting screw 36. In order to prevent the limiting screw 36 from loosening, an anti-loosening washer 35 can be sleeved on its outside. The adjustment rod 30 can slide inside the outer shell 1 through the adjustment groove 32. The limiting cylinder 33 can slide on one side of the outer shell 1 through the limiting hole 34.

[0021] Working principle: When using the locking mechanism 2, firstly, the locking ring 22 with anti-slip coating 21 is fitted onto the bicycle handlebars, ensuring that the locking ring 22 fits tightly against the surface of the handlebars. Then, through the locking hole 24 on the locking plate 25, the locking screw 28 is inserted between the two locking plates 25 and slidably fitted with the locking hole 24. Next, the locking nut 27 is threaded onto the outside of the locking screw 28 and rotated until it presses tightly against the locking plate 25, thereby achieving a stable lock of the locking ring 22 onto the bicycle handlebars. Since the locking ring 22 is made of soft material and has an anti-slip coating 21 on its inner side, it can increase the friction between the locking ring and the handlebars, preventing the handlebars from sliding or rotating in the locked state, and ensuring the safety and stability of the lock.

[0022] During the use of the adjustment mechanism 3, firstly, the adjustment rod 30 is inserted into the inner side of the housing 1 through the adjustment groove 32 at the upper end of the housing 1, ensuring that the adjustment rod 30 can slide freely in the adjustment groove 32. Next, according to the actual position and size of the bicycle handlebars, the position of the adjustment rod 30 is adjusted so that the limiting grooves 31 on both sides correspond to the limiting holes 34 on the housing 1 and the inserted limiting cylinders 33. Then, the limiting cylinders 33 are inserted into the limiting holes 34 from one side of the housing 1, ensuring that the limiting cylinders 33 can slide freely in the limiting holes 34. At this time, by rotating the limiting screw 36, it is threaded into the limiting cylinder 33 and gradually tightened until the limiting screw 36 presses against the limiting groove 31 of the adjustment rod 30, thereby fixing the position of the adjustment rod 30. To prevent the limiting screw 36 from loosening, an anti-loosening washer 35 can be fitted on its outer side. Through the adjustment of the adjustment mechanism 3, the position and angle of the locking mechanism 2 can be easily adjusted to adapt to bicycle handlebars of different sizes and shapes, ensuring the accuracy and stability of the locking.

Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
