Abstract
Description
Technical Field
[0001] The utility model relates to the field of carbon fiber bicycles, in particular to a concealed interchangeable head and seat column of a carbon fiber bicycle. Background Art
[0002] The carbon fiber seat post products currently produced are non-replaceable. The seat posts designed and produced traditionally have visible heads and are non-replaceable. During the manufacturing process, glue accumulation, lack of shape and yarn insertion are easy to occur, resulting in many problems in later use. Once any component is damaged, the entire seat post will be scrapped. There are disadvantages and improvements are needed. Summary of the invention
[0003] In view of the above-mentioned deficiencies in the prior art, the utility model provides a carbon fiber bicycle hidden interchangeable head and seat column which can perfectly solve the problem of aesthetic appearance and the problem that a certain component is damaged and cannot be replaced and reused.
[0004] The purpose of this utility model is achieved through the following technical solutions:
[0005] A carbon fiber bicycle hidden interchangeable seat tube column comprises a seat tube column, a seat tube column upper chuck, a locking threaded rod, a connecting rod, and a connecting rod side sliding column. The upper part of the seat tube column is provided with a seat tube column upper chuck, the seat tube column upper chuck has a sliding through hole, the upper part of the sliding through hole is provided with an upper strip-shaped clearance hole, a group of upper strip-shaped clearance holes are distributed on the upper part of the sliding through hole, the side of the connecting rod is provided with a connecting rod side sliding column, the connecting rod side sliding column is symmetrically arranged at both ends of the connecting rod, the connecting rod side sliding column has a threaded hole, chamfers are arranged at both ends of the threaded hole, the connecting rod side sliding column is adapted to the sliding through hole, the connecting rod side sliding column is inserted into the sliding through hole, and the connecting rod side sliding column slides in the sliding through hole.
[0006] The upper part of the locking threaded rod has a threaded rod upper head, the locking threaded rod is adapted to the threaded hole, the locking threaded rod is inserted into the threaded hole, the locking threaded rod slides in the threaded hole, the locking threaded rod passes through the upper strip-shaped clearance hole and is inserted into the sliding through hole, and a group of locking threaded rods are distributed at both ends of the connecting rod. Beneficial Effects
[0007] 1. The utility model has a hidden replaceable seat tube clamp, which makes its appearance more beautiful.
[0008] 2. The utility model avoids the entire product being scrapped due to a certain part of the chuck being damaged and unable to be repaired.
[0009] 3. The utility model eliminates the original embedded metal aluminum parts at the top of the original product contour, uses a round rod core shaft to be wound into a circle and embedded under the top of the product. During the molding process, the mold uses a cylindrical iron core to penetrate into the preset product, and the mold slider is marked with engraved lines for easy subsequent processing. It can be completed using a five-axis machine or an anti-shaping machine.
[0010] 4. This utility model solves the principle of beautiful appearance, extending service life and reducing the maintenance cost of later consumers. The advantage of this application is that compared with the visible chuck appearance design of traditional processes, the hidden replaceable design is more beautiful and simple. Due to the use of new technology, this application solves the problem of reduced product life due to irreparable damage to the internal structure of the product design. This invention only needs to replace one part to continue to use the product. BRIEF DESCRIPTION OF THE DRAWINGS
