Description

Technical Field

[0001] This utility model relates to the field of bicycle parts technology, and more specifically, to a bicycle with retractable handlebars. Background Technology

[0002] A bicycle, also known as a pedal bike or bicycle, is usually a small two-wheeled land vehicle. The front wheel of a bicycle is connected to the handlebars via a front fork. The top of the front fork is equipped with fork tips, and the handlebars are fixed to the left and right sides of the fork tips. When turning, the handlebars drive the front fork to rotate, controlling the bicycle's steering.

[0003] Existing bicycle handlebars lack adjustment functionality, making it impossible to customize the handlebars to the optimal size for users of varying body types. Furthermore, the traditional telescopic locking method, relying solely on bolts to secure the adjusted handlebars after extended use, struggles to guarantee stability. Handlebar wobbling during riding poses a significant safety hazard. Therefore, this paper proposes a bicycle with telescopic handlebars to address these issues. Utility Model Content

[0004] To overcome the aforementioned deficiencies of the prior art, embodiments of this utility model provide a bicycle with retractable handlebars. The technical problem to be solved by this utility model is that existing bicycle handlebars do not have an adjustable function, which makes it impossible to adjust the handlebars to the most suitable size for users with different body shapes. Furthermore, since the handlebars need to be retractable, if the traditional telescopic fastening method is used, after a long period of use, it is difficult to ensure the stability of the adjusted handlebars by simply tightening them with bolts. If the handlebars wobble during riding, it will cause a significant safety hazard.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a bicycle with retractable handlebars, including a main frame assembly, wherein retractable components are sleeved on both sides of the main frame assembly, and an external component is provided at the end of each retractable component away from the main frame assembly;

[0006] The external component includes a baffle plate 2, a hexagonal block fixedly connected to one side of the baffle plate 2, and bolts penetrating the baffle plate 2 and the hexagonal block. An extension strip is fixedly connected to one side of the baffle plate 2, and a connecting strip is fixedly connected to the end of the extension strip away from the baffle plate 2. Multiple locking holes 3 are opened through the surface of the connecting strip. A windshield is sleeved on the outer surface of the connecting strip. An insertion port is opened at the intersection of the windshield and the connecting strip. Multiple locking bolts 2 are provided on the surface of the windshield.

[0007] In a preferred embodiment, the telescopic assembly includes a sliding column with multiple flat grooves on its surface. A plug is fixedly connected to the inner cavity of the sliding column. Multiple locking holes are provided through the surfaces of both the sliding column and the plug. A stop plate is fixedly connected to the end of the sliding column away from the locking holes. A handle is fixedly connected to the side of the stop plate away from the sliding column. A hexagonal groove is provided on the surface of the end of the handle away from the stop plate. A screw hole is provided in the inner cavity of the hexagonal groove. A handle sleeve is fitted onto the surface of the handle.

[0008] In a preferred embodiment, the main frame assembly includes a center handle, with inner columns fixedly connected to both sides of the center handle. Each inner column has a plurality of flat grooves on its surface, an insertion hole on the surface of the inner column away from the center handle, a plurality of locking holes through the surface of each inner column, and a plurality of locking bolts through the surface of each inner column.

[0009] In a preferred embodiment, all of the multiple locking bolts 2 penetrate the windshield and lock holes 3 for locking, and the insertion port is the same size as the connecting strip. In later use, when the windshield is not needed, the locking bolts 2 can be directly removed, and the windshield and connecting strip can be separated for disassembly and installation. The fact that the insertion port is the same size as the connecting strip improves the stability of the connection between the windshield and the connecting strip, and the windshield can protect the hands from the cold winter wind and prevent frostbite.

[0010] In a preferred embodiment, the hexagonal slot and the hexagonal block have the same shape and volume, the hexagonal slot and the hexagonal block intersect, and the screw hole and the bolt thread intersect; by the interlocking of the hexagonal slot and the hexagonal block, it is prevented that after the baffle plate and the handle are connected, the baffle plate and the extension strip will rotate due to gravity due to time issues, which would affect the use.

[0011] In a preferred embodiment, the inner diameter of the insertion hole is the same as that of the insertion post, the shape and volume of the inner cavity of the sliding post are the same as those of the inner post, and the locking bolt one penetrates the locking hole two and the locking hole one; in later use, the stability can be improved by the double snap-fit ​​method, and the stability between the entire telescopic assembly and the main frame assembly is improved after the connection is completed because the shape and volume of the inner cavity of the sliding post are the same as those of the inner post.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. This utility model has an external component, so when the windshield is not needed, the second locking bolt can be removed directly, and the windshield can be separated from the connecting strip for easy disassembly and installation. The fact that the plug and the connecting strip are the same size improves the stability of the connection between the windshield and the connecting strip. The windshield can protect the hands from the cold winter wind, prevent frostbite, and improve the comfort of use.

[0014] 2. This utility model is equipped with a main frame assembly, a telescopic assembly, and an external assembly. Through the snap-fit ​​of hexagonal slots and hexagonal blocks, it avoids the second stop plate and the extension bar from rotating due to gravity due to time issues after they are connected to the handle, which would affect the use. In later use, the double snap-fit ​​method can improve stability. Furthermore, the shape and volume of the inner cavity of the sliding column are consistent with the inner column, which improves the stability between the entire telescopic assembly and the main frame assembly after the connection is completed.
