Description

Technical Field

[0001] This utility model belongs to the field of umbrella frame technology, specifically a carbon fiber umbrella frame. Background Technology

[0002] The umbrella frame refers to the individual ribs that support the umbrella. With technological advancements, umbrellas have evolved, from the early oil-paper umbrellas to the diverse array of styles available. Along with the changes in the canopy, the ribs have also changed. Previously, umbrella ribs were mostly made of wood or bamboo; later, iron, steel, aluminum alloy, electroplated, and resin ribs appeared. Steel ribs are the strongest and most durable, not easily broken, and have a long lifespan. Iron ribs are sturdy and not easily broken, offering good wind resistance, but they are prone to rusting over time. Aluminum, electroplated, and resin ribs are relatively lightweight and portable. This type of frame is commonly used in lightweight umbrellas, but its disadvantages include being easily broken and having poor wind resistance. To make it easier to use, some umbrella frames are now made of carbon fiber, which not only has the advantages of being lightweight but is also less prone to breakage, thus increasing its lifespan. However, most current umbrella frames have a fixed opening and closing position when in use, fixing the umbrella after it has been opened to a certain extent. This makes it less versatile. If you need to pass through poor passageways for a long time, you need to tilt the umbrella, and you need to use a lot of force to press the opening and closing button, which is inconvenient to use.

[0031] 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.

[0032] Example 1

[0033] A carbon fiber umbrella frame includes a main body component 1, an adjustment component 2, and an end component 3.

[0034] The main component 1 includes a main rod 11, and the end component 3 is fixedly installed at one end of the main rod 11. The adjustment component 2 is slidably engaged on the main rod 11 at one end near the end component 3. A support rod 12 is evenly rotatably installed on the end component 3, and a diagonal brace 13 is evenly rotatably installed on the adjustment component 2. The diagonal brace 13 is rotatably connected to the support rod 12, and both the support rod 12 and the diagonal brace 13 are made of carbon fiber.

[0035] The adjusting assembly 2 includes a threaded tube 21 and a movable tube 22. The threaded tube 21 is slidably engaged with the main rod 11, and the movable tube 22 is sleeved on the main rod 11. A connecting tube 23 is rotatably installed at the lower end of the movable tube 22. The connecting tube 23 is threadedly connected to the lower end of the threaded tube 21, and one end of the diagonal brace 13 is rotatably installed on the movable tube 22.

[0036] A handle 14 is fixedly installed at the lower end of the main rod 11, and both sides of the main rod 11 are vertically provided with arc-shaped grooves 15.

[0037] The first ball bearing 24 is embedded inside the threaded tube 21 and is engaged inside the groove 15.

[0038] The connecting pipe 23 has an arc-shaped groove 25 with an annular structure inside. The second ball 26 is engaged inside the arc-shaped groove 25, and the other side of the second ball 26 is engaged inside the groove 15.

[0039] The upper end of the main rod 11 is provided with evenly spaced pin holes 27 inside the groove 15, and the upper end of the threaded tube 21 is fitted with a pin 28. The pin 28 has a T-shaped structure, one end of the pin 28 is inserted into the pin hole 27, and a spring 29 is fitted in the middle of the pin 28. One side of the spring 29 is pressed against the inner side of the threaded tube 21.

[0040] A plane bearing 210 is fixedly installed on the lower surface of the movable tube 22. The connecting tube 23 is rotatably installed on the movable tube 22 through the plane bearing 210, and the movable tube 22 is sleeved on the threaded tube 21.

[0041] See Figure 1-4During use, the position of the threaded tube 21 is adjusted according to the requirements. During adjustment, pulling the pin 28 compresses the spring 29, causing one end of the pin 28 to disengage from the pin hole 27, facilitating the movement of the threaded tube 21 on the main rod 11. During this movement, the first ball bearing 24 rolls along the groove 15 on the main rod 11, restricting the rotation of the threaded tube 21 and facilitating position adjustment. After adjustment, the pin 28 is released, causing the spring 29 to push the pin 28 into the pin hole 27, facilitating the fixing of the threaded tube 21. After fixing, opening and closing the support rod 12 pushes the connecting tube 23, allowing the movable tube... 22 is fitted onto the threaded tube 21, and the connecting tube 23 contacts the lower end of the threaded tube 21. Tightening the connecting tube 23 causes the second ball 26 to roll inside the arc groove 25, thereby connecting the connecting tube 23 to the lower end of the threaded tube 21. This allows the support rod 12 to be opened by the diagonal brace 13. When the connecting tube 23 is rotated, it rotates on the movable tube 22 through the plane bearing 210, preventing the movable tube 22 from rotating when the connecting tube 23 is rotated. This makes it convenient to use and easy to operate. When closing, simply tightening the connecting tube 23 disengages it from the threaded tube 21, thus completing the storage of the support rod 12. This also makes it convenient to use.

[0042] Example 2

[0043] Based on Embodiment 1, a method for easily replacing the end component 3 has been added.

[0044] The end assembly 3 includes a sealing head 31, and the support rod 12 is evenly rotated and installed on the outside of the sealing head 31. The lower end of the sealing head 31 is provided with a threaded hole 32, and the upper end of the main rod 11 is fixedly installed with a threaded rod 33. The main rod 11 is threadedly connected to the threaded hole 32 on the sealing head 31 through the threaded rod 33. The upper end of the sealing head 31 is fixedly installed with a spherical buffer ball 34.

[0045] See Figure 1-4 When in use, a buffer ball 34 is installed at one end of the sealing head 31 to reduce the impact force of this invention on the ground during placement, preventing damage to the end assembly 3 during placement. The end assembly 3 is installed on the main rod 11 through the threaded rod 33 and the threaded hole 32. When the end assembly 3 is damaged, the sealing head 31 can be replaced for continued use, which is convenient to operate and easy to replace.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
