Detailed Implementation

[0019] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0020] like Figure 1-4As shown in the figure, the carbon tube umbrella rod structure provided by this utility model includes an outer tube 1, an inner tube 5 inserted into the inner tube 1, a locking component 6 between the outer tube 1 and the inner tube 5, both the outer tube 1 and the inner tube 5 include an inner spiral carbon cloth layer 4, the outer wall of the inner spiral carbon cloth layer 4 is provided with axial carbon cloth strips 3 distributed in a centrally symmetrical manner, and the outer wall of the axial carbon cloth strips 3 is wound with an outer spiral carbon cloth layer 2.

[0021] Specifically, in this embodiment, it includes an outer tube 1, with an inner tube 5 inserted inside the outer tube 1. Both the outer tube 1 and the inner tube 5 are tubular structures. A locking component 6 is provided between the outer tube 1 and the inner tube 5 to fix the outer tube 1 and the inner tube 5. Both the outer tube 1 and the inner tube 5 include an inner spiral carbon cloth layer 4. The outer wall of the inner spiral carbon cloth layer 4 is provided with axially symmetrically distributed carbon cloth strips 3. The outer wall of the axially symmetrically distributed carbon cloth strips 3 is wound with an outer spiral carbon cloth layer 2. The inner spiral carbon cloth layer 4 and the axially symmetrically distributed carbon cloth strips 3 are provided with an inner spiral carbon cloth layer 4. Both the carbon cloth strip 3 and the outer spiral carbon cloth layer 2 are made of carbon fiber. The inner spiral carbon cloth layer 4, the axial carbon cloth strip 3 and the outer spiral carbon cloth layer 2 are immersed in impregnation material and then wrapped around the mandrel. After the impregnation material is cured, the carbon tube is formed. Then the mandrel can be removed. The axial carbon cloth strip 3 is a tubular structure formed by multiple carbon fiber strips of equal width. The inner spiral carbon cloth layer 4 and the outer spiral carbon cloth layer 2 are both formed by spiral winding, and the spiral directions of the inner spiral carbon cloth layer 4 and the outer spiral carbon cloth layer 2 are different.

[0022] This utility model provides a carbon fiber umbrella pole structure, which forms an outer tube 1 and an inner tube 5 of a carbon fiber tube through an outer spiral carbon cloth layer 2, an axial carbon cloth strip 3 and an inner spiral carbon cloth layer 4, thereby giving the umbrella pole the effect of high strength and light weight, making the umbrella pole of the fishing umbrella more convenient to carry.

[0023] In another embodiment of this utility model, a sleeve tube 14 is fixed to the top end of the inner tube 5, and a connecting tube 13 is integrally formed at the top end of the sleeve tube 14. One end of the connecting tube 13 is rotatably connected to a rotating tube 15. A locking component three 17 is provided at the end of the rotating tube 15 away from the connecting tube 13. The locking component three 17 can lock the rotatable connection between the connecting tube 13 and the rotating tube 15. A locking component two 16 is provided at the end of the connecting tube 13 away from the rotating tube 15. An insertion hole 18 is provided on the outer wall of the rotating tube 15. The locking component two 16 can press and fix the umbrella handle inserted into the insertion hole 18. Specifically, the locking component two 16 and the locking component three 17 are both prior art.

[0024] In another embodiment of this utility model, the locking assembly 6 includes a fixing ring 7 fixed to the top of the outer tube 1. The top of the fixing ring 7 is integrally formed with a threaded ring 8, and the outer thread of the threaded ring 8 is connected to a locking ring 9. The top of the threaded ring 8 is integrally formed with centrally symmetrically distributed claws 10. One side of the outer wall of the claws 10 is provided with a bevel 12, and the inner wall of the locking ring 9 is provided with a conical surface 11. By rotating the locking ring 9, the claws can lock and fix the inner tube 5 by the compression of the conical surface 11 on the inner wall of the locking ring 9, thereby making it easy to adjust and fix the extension length of the inner tube 5, and thus enabling the umbrella pole to adjust its length according to actual needs. The outer wall of the claws 10 near the inner tube 5 is provided with anti-slip texture 19, which increases the friction. The outer wall of the outer tube 1 is provided with a protective layer 20, which is an epoxy resin coating, so that the outer walls of the outer tube 1 and the inner tube 5 have good wear resistance.

[0025] Working principle: When it is necessary to change the length of the inner tube extension, the inner tube is pulled out from the inside of the outer tube, and then the locking ring 9 is rotated so that the pawl can lock and fix the inner tube 5 by the compression of the conical surface 11 on the inner wall of the locking ring 9, thereby fixing the extension length of the inner tube 5.

[0026] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
