Detailed Description

The present invention will be described in further detail with reference to the following embodiments.

Example 1

As shown in fig. 1 to 8, a foldable umbrella rib of a sunshade includes a rib 1 and an extension rib 2, the extension rib 2 is foldably pivoted to the end of the rib 1 by a fastener, and the extension rib 2 can be locked to the rib 1 and connected together when in an open state.

The concrete structure is as follows: rib 1 is hollow square or rectangle tubular structure, extension bone 2 is that the upper end is sealed, lower extreme open-ended cross-section is the tubular structure of U-shaped, usually both cross-section size complex, make extension bone 2 fold and overlap in rib 1 outside, rib 1's the horizontal spout 11 that has seted up that runs through of the terminal left and right sides, the fastener adopts a round pin axle 3, corresponding pinhole 22 has been seted up to the inner end left and right sides of extension bone 2, round pin axle 3 passes left pinhole 22, spout 11, pinhole 22 on right side, with extension bone 2 and rib 1 collapsible ground pin joint together, and round pin axle 3 can follow spout 11 front and back slip. The sliding groove 11 is provided with a latch 12 near the inner end, so that the inner end of the sliding groove 11 is a lock hole 13 with an opening, and when the elongated bone 2 is pushed inwards in an unfolded state, the pin shaft 3 passes through the latch 12 and falls into the lock hole 13 at the inner end of the sliding groove, so that the elongated bone 2 is positioned and cannot rotate or slide. One side of the upper end surface of the extension rib 2 close to the umbrella ribs 1 is formed into a circular arc-shaped guide surface 21 convenient for rotation, and the lower end of the extension rib 2 gradually inclines upwards towards the tail end direction in an opening state, so that the effects of reducing the weight of the umbrella stand and improving the flexibility of umbrella stand ribs are achieved.

The extension bone 2 is made of rigid material or plastic material.

The operation process is as follows:

the folded extension bone 2 is rotated and unfolded, as shown in fig. 3 and 4, after the extension bone 2 is rotated by 180 degrees, the extension bone 2 is horizontally connected with the umbrella rib 1, as shown in fig. 5 and 6, the extension bone 2 is pushed inwards, as shown in fig. 7 and 8, the extension bone 2 passes through the latch 12, falls into the lock hole 13 and is positioned, and cannot be rotated and slid, so that the positioning and fixing are realized. After use, when the umbrella is folded, the extension bone 2 is pulled outwards, the extension bone 2 passes through the latch 12 and falls into the sliding groove 11, and then the extension bone 2 is pulled to the outside, so that the extension bone 2 can be folded and sleeved outside the umbrella rib 1, and can be rotated and folded, and the folding is shown in figures 1 and 2. The structural schematic diagram of the sunshade umbrella is shown in figures 10-12.

Example 2

As shown in fig. 9, the left and right sides of the end of the rib 1 are transversely provided with a sliding groove 11 in a penetrating manner, the fastening member is a bolt 3a, the left and right sides of the inner end of the extension rib 2 are provided with corresponding connecting holes, the bolt penetrates through the connecting hole on the left side, the sliding groove and the connecting hole on the right side to foldably connect the extension rib and the rib together, the bolt 3a can slide along the sliding groove 11, the sliding groove 11 is provided with a boss 12a with an inclined surface at a position close to the inner end, so that the inner end of the sliding groove becomes a positioning groove 13a with an opening, when the extension rib is pushed inwards in an unfolding state, the bolt 3a penetrates through the boss 12a to fall into the positioning groove 13a to position and fix the extension rib 2, and the rest is similar to and consistent with embodiment 1.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the technical principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
