Abstract
Description
Technical Field
[0001] This utility model relates to the field of umbrella component technology, specifically to a three-in-one middle butterfly and tail buckle connection structure used in umbrella assembly, mainly for achieving efficient and stable connection between the middle butterfly, tail buckle and umbrella ribs. Background Technology
[0002] In the traditional assembly process of umbrellas, the umbrella ribs are usually connected by riveting or screwing. When riveting, specialized riveting equipment is required to press and fix the parts. This not only makes the equipment highly dependent on the equipment, but also, if the pressure is not properly controlled during the riveting process, it can easily cause deformation or damage to the middle flap or tail buckle, affecting the service life of the parts. When screwing, each screw needs to be tightened manually, which is inefficient. Moreover, over long-term use, the screws are prone to loosening, which leads to a decrease in the connection stability between the middle flap, tail buckle and umbrella ribs, affecting the normal use of the umbrella.
[0003] Furthermore, the relative movement between the tail buckle and the middle flap in traditional connection methods is severely restricted, preventing flexible rotation. When the umbrella is opened or closed, the rotation of the umbrella ribs is constrained, easily causing jamming and reducing the smoothness of umbrella use. Therefore, there is an urgent need for a middle flap tail buckle structure that can solve the problems of low assembly efficiency, poor connection stability, and insufficient movement flexibility. Utility Model Content
[0004] To address the aforementioned problems, this utility model provides a novel three-in-one butterfly tail buckle structure, with the specific structural design as follows: A butterfly tail buckle connection structure for umbrella ribs, wherein the umbrella ribs include canopy ribs and supporting ribs, the butterfly tail buckle connection structure includes a tail buckle and a middle butterfly, the tail buckle includes a rotating shaft and a connector connected to the rotating shaft, the bottom of the connector is provided with a supporting rib cavity for installing the supporting rib; the middle butterfly includes a canopy rib mounting cavity for installing the canopy ribs and a tail buckle mounting groove located below the canopy rib mounting cavity for movably installing the tail buckle, the canopy rib mounting cavity has canopy rib mounting holes on both sides of the canopy rib mounting cavity, the canopy ribs pass through the canopy rib mounting holes, the rotating shaft is movably installed in the tail buckle mounting groove, and the canopy ribs are located above the rotating shaft.
[0005] Furthermore, an umbrella surface and rib mounting sleeve is provided on the outer wall of the umbrella surface and rib mounting cavity at the position corresponding to the umbrella surface and rib mounting hole.
[0006] Furthermore, the rotating shaft includes a pair of wheel-shaped rotating heads installed in the tail buckle mounting groove and a rotating shaft disposed between the wheel-shaped rotating heads.
[0007] Furthermore, the outer wall of the supporting umbrella rib cavity is provided with a supporting umbrella rib fastening groove.
[0008] The beneficial effects of this utility model are as follows:
[0009] 1. Improved assembly efficiency: The traditional riveting and screw-locking process has been eliminated. Assembly can be completed with only simple steps of inserting the tail buckle and inserting the umbrella ribs. There is no need to rely on complex equipment, which greatly shortens the assembly time and improves the production efficiency of umbrellas.
[0010] 2. Ensure connection stability: The umbrella ribs and canopy form a reliable limit on the tail buckle after passing through the middle flap, which can effectively prevent the tail buckle from falling off the middle flap and avoid the connection failure problem caused by loose screws in traditional systems, ensuring that the middle flap, tail buckle and umbrella ribs maintain a stable connection in the long term.
[0011] 3. Enhanced flexibility of use: The tail buckle can rotate within a range of 0-180 degrees. When the umbrella is opened or closed, the umbrella ribs can drive the tail buckle to rotate flexibly, avoiding jamming and improving the smoothness of umbrella use and user experience.
[0012] 4. Reduced component wear: No need to rivet, squeeze, or tighten screws on components, reducing damage to the middle and tail buckles during assembly and extending the service life of components. Attached Figure Description

[0018] The present invention will now be described in detail with reference to the accompanying drawings:
[0019] Please refer to Figure 1-5A butterfly-tail buckle connection structure for umbrella ribs, wherein the umbrella ribs include canopy ribs 31 and supporting ribs 32, and the butterfly-tail buckle connection structure is used to connect the canopy ribs 31 and supporting ribs 32, so that the tail buckle can rotate within a range of 0-180 degrees under the drive of the supporting ribs 32. The butterfly-tail buckle connection structure includes a tail buckle 1 and a butterfly 2. The tail buckle 1 includes a rotating shaft 11 and a connector 12 connected to the rotating shaft 11. The bottom of the connector 12 is provided with a mounting point for the supporting ribs 32. The umbrella support cavity 13; the middle butterfly 2 includes an umbrella surface and rib mounting cavity 22 for mounting the umbrella surface and ribs 31 and a tail buckle mounting groove 21 located below the umbrella surface and rib mounting cavity 22 for movably mounting the tail buckle 1. The umbrella surface and rib mounting cavity 22 has umbrella surface and rib mounting holes on both sides. The umbrella surface and ribs 31 pass through the umbrella surface and rib mounting holes. The rotating shaft 11 is movably mounted in the tail buckle mounting groove 21. The umbrella surface and ribs 31 are located above the rotating shaft 11.
[0020] Assembly process: such as Figure 2 As indicated by the arrow, the tail buckle 1 passes downward through the umbrella rib mounting cavity 22 until the rotating shaft 11 is installed in the tail buckle mounting groove 21. The umbrella ribs 31 have umbrella rib mounting holes on both sides of the umbrella rib mounting cavity 22. After installation, the umbrella ribs 31 hold the tail buckle 1 in the middle butterfly 2. The connector 12 rotates within a range of 0-180° with the rotating shaft 11 as its rotation axis, while the supporting rib 32 is inserted into the supporting rib cavity 13 on the connector 12. The rotation of the connector 12 causes the supporting rib 32 to rotate within a range of 0-180° as well.
[0021] The outer wall of the umbrella canopy and rib mounting cavity 22 is provided with an umbrella canopy and rib mounting sleeve 23 at the position corresponding to the umbrella canopy and rib mounting hole. The umbrella canopy and rib mounting sleeve 23 facilitates the installation and positioning of the umbrella canopy and rib.
[0022] The rotating shaft 11 includes a pair of wheel-shaped rotating heads 111 installed in the tail buckle mounting groove 21 and a rotating shaft disposed between the wheel-shaped rotating heads 111. The tail buckle mounting groove 21 is U-shaped, and the wheel-shaped rotating heads 111 rotate within the tail buckle mounting groove 21.
[0023] The outer wall of the supporting umbrella rib cavity 13 is provided with a supporting umbrella rib fastening groove 131. After the supporting umbrella rib 32 is inserted into the supporting umbrella rib cavity 13, the supporting umbrella rib can be fastened with a fastener that cooperates with the supporting umbrella rib fastening groove 131 to prevent it from falling off.
