Description

Technical Field

[0001] This utility model relates to the field of bicycles, and in particular to an integrated molding device for embedding carbon tubes inside carbon fiber bicycle handlebars. Background Technology

[0002] In the current assembly process of carbon fiber bicycles, most brake cables are directly installed on the outside of the handlebars or inside the handlebar steel tube. Installing them inside the handlebar steel tube often leads to difficulties in threading the cable, which prolongs the assembly time, increases labor costs, and causes economic losses to users. Therefore, there is a need for a carbon fiber bicycle handlebar embedded carbon tube integral molding device that can assist workers in quickly threading the cable to solve the above problems. Summary of the Invention

[0003] This utility model addresses the aforementioned shortcomings of existing technologies by providing an integrated carbon fiber tube embedded in the handlebars, which allows for quick and easy cable threading, solves the problem of difficult cable threading, saves time and effort, shortens bike assembly time, reduces labor costs, improves assembly efficiency, and provides smooth operation without jamming.

[0004] The objective of this utility model is achieved through the following technical solution: A one-piece molding device for embedding carbon tubes in carbon fiber bicycle handlebars includes a carbon fiber bicycle handlebar, handlebar grips, and one-piece molded tubes. The handlebar grips are connected to both ends of the carbon fiber bicycle handlebars and are symmetrically arranged. Two brakes are connected to the outer side of the carbon fiber bicycle handlebars and are symmetrically arranged. Two one-piece molded tubes are connected to the inner side of the carbon fiber bicycle handlebars and are symmetrically arranged. An auxiliary slide rail is provided on the inner side of the carbon fiber bicycle handlebars, and two positioning grooves are provided on the inner side of the auxiliary slide rails and are symmetrically arranged. A protective plug is connected to the top of the auxiliary slide rail.

[0005] The protective plug of this invention is connected to a first brake cable on its inner side. The first brake cable slides inside the protective plug. One end of the first brake cable is connected to the vehicle brake, and the other end of the first brake cable passes through the protective plug and connects to a first auxiliary connecting block. Two second brake cables are provided on the inner side of the carbon fiber bicycle handlebar. The second brake cables are arranged symmetrically.

The second fixed carbon fiber tube is connected to the lower part of the auxiliary slide rail, and the second fixed carbon fiber tube is connected to the outer side of the auxiliary slide rail. The second fixed carbon fiber tube slides in the auxiliary slide rail.

[0007] The present invention describes a first fixed carbon fiber tube with a first positioning protrusion on its outer side, which is connected to a positioning groove and slides within the groove. A second fixed carbon fiber tube has a second positioning protrusion on its outer side, which is also connected to a positioning groove and slides within the groove. The first fixed carbon fiber tube has two first fastening protrusions on its inner side, symmetrically arranged. The second fixed carbon fiber tube also has two second fastening protrusions on its inner side, symmetrically arranged. The first and second fastening protrusions correspond to each other. An auxiliary connecting block is connected to the outer side of the first fastening protrusion. The lower part of the auxiliary connecting block is connected to the second fastening protrusion. The outer side of the second fastening protrusion is connected to the second auxiliary connecting block, and the upper part of the auxiliary connecting block is connected to the first fastening protrusion.

[0018] Example 2: The protective plug 04 of this utility model is connected to the first brake line 03 on the inside. The first brake line 03 slides inside the protective plug 04. One end of the first brake line 03 is connected to the brake 09, and the other end of the first brake line 03 passes through the protective plug 04 and connects to the first auxiliary connecting block 07. Two second brake lines 06 are provided on the inside of the carbon fiber bicycle handlebar 01. The second brake lines 06 are arranged symmetrically.

[0019] Example 3: This utility model has a second brake cable 06 connected at one end to a second auxiliary connecting block 08, and a first fixed carbon fiber tube 12 connected to the inner side of the auxiliary slide rail 10. The first fixed carbon fiber tube 12 slides within the auxiliary slide rail 10. The second fixed carbon fiber tube 13 is connected to the lower part of the auxiliary slide rail 10, and the second fixed carbon fiber tube 13 is connected to the outer side of the auxiliary slide rail 10. The second fixed carbon fiber tube 13 slides within the auxiliary slide rail 10. When the brake 09 is pressed, the first brake cable 03 drives the second brake cable 06 to slide within the integrally formed tube 05 through the first fixed carbon fiber tube 12 and the second fixed carbon fiber tube 13. The first fixed carbon fiber tube 12 and the second fixed carbon fiber tube 13 combine to form a carbon tube, which is smooth to use and avoids jamming.

[0021] Example 5: Installation steps: During assembly, first connect and secure auxiliary connecting blocks 07 (connecting one end of brake cable 03 to one end of brake cable 06) and 08 using fixed carbon fiber tubes 12 and 13. Then, thread brake cable 06, fixed carbon fiber tubes 12 and 13, and brake cable 03 together into the integrated molding tube 05. Finally, insert the integrated molding tube 05 into the carbon fiber bicycle handlebar 01. Pass the other end of brake cable 03 through the protective plug 04 and install it on the brake 09. Then install the protective plug 04 on the one-piece molded tube 05 to complete the handlebar cable assembly. Handlebar cable threading is quick, solving the problem of difficult handlebar cable threading, saving time and effort, shortening the assembly time, reducing labor costs, and improving assembly efficiency.
