Umbrella telescopic adjustment device

The present invention relates to a telescopic adjustment device for a pole in an umbrella, and more particularly to a telescopic adjustment device for a large outdoor umbrella for outdoor landing.

According to the large umbrellas used in beaches, gardens or markets, there are usually umbrella surfaces that can form a large shielding area, but the ribs, bones and joints used to support the umbrella surface are similar to ordinary umbrellas.

In the general large umbrella structure shown in the first and second figures, in the specific length of the rod 9, the branch pipe 94 is provided with an upper nest 91 near the top end, and a lower nest 92 below the bottom to support the support. The umbilical group of the canopy includes a joint 95 disposed in the middle of the whole rib 93, and a slanted support surface between the joint 95 of each rib 93 and the lower dam 92 in a normal state. .

The branch pipe 94 above the rod 9 of the conventional large umbrella must be inserted into the lower branch pipe 97 and its jacket seat 98, and then the wrench 99 is pushed to push the clamp block 991 to clamp the upper branch pipe 94, and the adjustment rod is adjusted. The upper branch pipe 94 of 9 combines the length of use of the lower branch pipe 97. However, the weight of the large umbrella and the upper branch pipe 94 is too heavy, and the clamping force of the wrench 99 is insufficient, so that the weight of the large umbrella causes the upper branch pipe 94 to slide downward, and the height and length of the set bar 9 must be adjusted again. Relatively wasted Force and time, and easy to damage. Therefore, how to solve the above-mentioned shortcomings and shortcomings of the prior art is the subject of improvement for those involved in this industry.

The main purpose and function of this creation is that the large umbrella has a double clamp clamping structure, which can quickly adjust the length of the rod used in the umbrella, and improve the clamping force and structural strength to avoid the weight of the umbrella. The upper branch pipe is slid down and displaced, which is more durable and improves the use efficiency.

In order to achieve the goal, the present invention provides an umbrella telescopic adjustment device which is fixed at the top of the lower branch of the middle rod for inserting the lower portion of the upper branch into the lower branch; the telescopic adjustment device includes : a connecting seat has a sleeve with an opening facing downward for fixing to the peripheral edge of the top end of the lower branch pipe, and a clamping tube extending upward from the top end of the sleeve, and the lower portion of the upper branch pipe is inserted into the lower branch pipe through the clamping tube Providing a connecting opening at the periphery of the sleeve and the lower branch pipe and a pivoting portion on the outer side thereof, a screw thread on the outer circumference of the clamping cylinder, and a tapered pipe clamp formed along the tapered shape, along the tapered pipe clamp The top edge of the top end is provided with a plurality of channels extending downwardly; a wrench is pivotally connected between the pivoting portions on both sides of the sleeve, and an eccentric head entering the opening is provided at one end of the wrench to be pressed inwardly On the surface of the upper branch pipe; a fixing nut is provided with a screw hole downwardly, and a taper hole is formed by the screw hole extending upwardly; the screw hole of the fixing nut is downwardly locked to the pin barrel a thread that causes the tapered clamping hole to be pressed inwardly against the tapered tube clamp to Clamp system positioned on the support tube surface.

In a preferred embodiment, a spacer is disposed in the opening of the sleeve of the connecting seat and the lower branch tube, and the eccentric head of the wrench pushes the block to be pressed against the surface of the upper branch tube.

In a preferred embodiment, the collet of the connecting seat and the outer circumference of the conical tube clip are provided with a thread. Further, a screw thread is arranged on the inner circumference of the tapered clamping hole of the fixing nut to be connected to the screw hole.

In a preferred embodiment, the inner circumference of the tapered pipe clamp of the connecting seat is provided with a plurality of pressing strips. Further, the fixing nut is provided with a plurality of operation portions at intervals around the outer circumference, and one of the operation portions is provided with a tab having an operation hole.
