Description

Middle rod unfolding and folding structure of multi-fold umbrella

Technical Field

The utility model relates to the field of umbrellas, in particular to a middle rod unfolding and folding structure of a multi-fold umbrella.

Background

In the prior art, the multi-fold umbrella generally comprises a telescopic middle rod, an upper nest connected with the top end of the middle rod, a lower nest movably sleeved with the middle rod, and a multi-fold umbrella framework pivoted with the upper nest and the lower nest, wherein adjacent tube bodies of the existing middle rod are positioned through an elastic positioner (commonly used as a slingshot or a marble) when being unfolded, so that the middle rod is ensured to be kept in an unfolded state.

The middle rod of the multi-fold umbrella has two setting modes at present, wherein the first multi-fold umbrella has a big-end-up structure after the middle rod is unfolded (i.e. the outer tube is arranged at the bottom after the middle rod is unfolded), and the second multi-fold umbrella has a big-end-down structure after the middle rod is unfolded (i.e. the inner tube is arranged at the bottom after the middle rod is unfolded); for the middle rod of the second multi-fold umbrella, the lower nest is downwards moved to push the positioning head of the elastic positioner by the lower nest, so that the positioning head of the elastic positioner is inwards contracted, and the pipe body of the middle rod is released from positioning fit, so that the middle rod can be contracted; the middle rod of the second multi-fold umbrella is of a structure with a small upper part and a big lower part after being unfolded, so that the gap between the inner wall of the lower nest and each pipe body of the middle rod is changed from the upper part to the lower part, and the positioning head of the elastic positioner matched with the pipe body with the upper middle rod is larger to ensure that the positioning head of the elastic positioner is contacted with the lower nest, if the positioning head is not enough in size, the pipe body of the middle rod part cannot be stably released from the positioning fit, and the umbrella is not smooth and stable to use; therefore, the elastic positioner adopted by the middle rod of the second multi-fold umbrella is a slingshot at present, and compared with a slingshot, the slingshot can be provided with a bigger positioning head, but the main body of the slingshot is V-shaped, and the slingshot is directly embedded in the pipe body of the middle rod, so that the slingshot is not firmly matched in the pipe of the middle rod, and the slingshot is easy to shift to cause the failure of the middle rod, so that the multi-fold umbrella is unreliable to use; in addition, for the middle rod of the second multi-fold umbrella, the lower nest is easy to wear because the positioning head of the elastic positioner needs to be pushed to release the positioning fit between the middle rod tube bodies.

When the multi-fold umbrella is opened (namely, when the middle rod 1 is unfolded), the middle tube pushing piece 19 is separated from and abuts against the outer tube positioning piece 182, the outer tube positioning piece 182 automatically rotates and resets under the action of the outer tube positioning spring 183 to enable the outer tube positioning head 1821 to move outwards, and at the moment, the upper side and the lower side of the extension tube sliding block 172 are respectively limited by the outer tube positioning head 1821 and the outer tube blocking part 133 to position the outer tube 13 and the extension tube 17, so that the outer tube 13 and the extension tube 17 of the middle rod 1 keep an unfolded state; when the multi-fold umbrella is folded, a user pulls the lower nest 3 downwards to enable the middle tube 12 to move downwards relative to the outer tube 13, so that the middle tube pushing piece 19 abuts against the inclined abutting surface 1822 of the outer tube positioning piece 182 to drive the outer tube positioning piece 182 to rotate inwards, the outer tube positioning head 1821 of the outer tube positioning piece 182 moves inwards to release the limit on the upper side of the extension tube sliding block 172, and therefore the positioning between the outer tube 13 and the extension tube 17 is released, and under the action of the lower nest 3, the outer tube 13 can be retracted into the extension tube 17 to achieve the shrinkage of the middle rod 1.

As can be seen from the foregoing, the outer tube 13 and the middle tube 12 are respectively provided with the outer tube elastic positioner 18 and the middle tube pushing member 19, so that the positioning engagement between the outer tube 13 and the extension tube 17 is released by the downward movement of the middle tube 12, and thus the positioning engagement between the outer tube 13 and the extension tube 17 is released without the need of the lower nest 3 pushing the outer tube positioning head 1821 of the outer tube elastic positioner 18, thereby ensuring that the positioning engagement between the outer tube 13 and the extension tube 17 can be effectively released, and the umbrella can be used more smoothly and stably; in addition, since the lower nest 3 does not need to abut against the outer tube positioning head 1821 of the outer tube elastic positioner 18, the outer tube positioning head 1821 does not need to be too large in size, so that the outer tube elastic positioner 18 does not need to adopt a slingshot structure, and meanwhile, the outer tube elastic positioner 18 of the present utility model can be more firmly matched with the outer tube 13 (such as the outer tube elastic positioner 18 is completely tightly matched with the outer tube 13 in the circumferential direction or locked by a fastener), so that the use of the multi-fold umbrella is reliable and stable.

It should be noted that the outer tube elastic positioner 18 is not limited to the positioning between the outer tube 13 and the extension tube 17 by limiting the upper and lower sides of the extension tube slider 172 by the outer tube positioning head 1821 and the outer tube stop 134, respectively; the utility model can also be that the side wall of the upper end of the extension tube 17 is provided with an extension tube positioning hole, and the outer tube positioning head 1821 movably passes through the extension tube positioning hole to control whether the outer tube 13 and the extension tube 17 are positioned or not.

In the second embodiment of the present utility model, the outer tube slider 132 and the extension tube slider 172 may be respectively fitted to the outer tube 13 and the extension tube 17 without forming holes in the outer tube 13 and the extension tube 17, for example, the outer tube 13 is punched to form the outer tube slider 132 or the outer tube slider 132 is welded to the inner wall of the outer tube 13, the extension tube 17 is punched to form the extension tube slider 172 or the extension tube slider 172 is welded to the inner wall of the extension tube 17, so that no holes are visible when the whole middle rod 1 is unfolded, and the whole middle rod 1 has good aesthetic property and strength.

As can be seen from the foregoing, in the second embodiment of the present utility model, the extension and retraction of the middle rod 1 is controlled by the movement of the inner tube 11, so that the extension and retraction of the middle rod 1 is more stable, reliable and smooth.
