Structure for positioning umbrella stick

Abstract

A locating structure for the ribs of umbrella is composed of a mainshaft pivoted with the first and the second holders, and a rib mechanism consisting of the multiple supporting ribs pivoted to the second holder via their pivot elements with lug comprising pin and stop block and the multiple pull rods with one end pivoted to the first holder and another end pivoted to said pin. Its advantages are high strength and long service life.

Description

technical field [0001] The invention relates to an umbrella rib structure, in particular to an umbrella rib positioning structure which can make the supporting connection of the umbrella rib not easy to fall off, thereby ensuring the assembly and use quality of the umbrella rib. Background technique [0002] Umbrellas or parasols are commonly used items in modern people's lives. Whether they are sheltering from wind and rain or preventing sun exposure, they can bring considerable convenience. The failure rate of general umbrellas is quite high, and the main reason is that the joints between the ribs of umbrellas often cannot withstand various customary operations or relatively harsh use environments. As shown in Figure 7, 7A and Figure 8 As shown, the existing umbrella structure mainly includes a central axis rod 90 together with the handle, on which the central axis rod 90 is provided with a slidable first nest body 91, a second nest body 92 and an extension spring 93 abut...

AI Technical Summary

Problems solved by technology

[0003] Although the above-mentioned umbrella structure can realize the basic function of connecting the umbrella ribs, when purchasing an umbrella, in order to confirm the structural strength of the umbrella, the general consumer usually pulls it around on the supporting ribs 94 in the ring to test. In this way, the supporting umbrella rib 94 will be subject to a downward pulling force F, that is, the pivot joint 97 will produce a mutual pressing force relative to the pull rod 96, so that the pivot tip 99 of the pivot joint 97 will be separated from the pivot joint 97. The hooking position of the pivotal hook portion 98 supporting the umbrella rib 94 even causes the pivotal hook portion 98 to break away from the hooking of the pivot tip 99 and fall off, resulting in a serious lack of quality (ie defective product).

Furthermore, when the use of the umbrella faces a strong wind or a typhoon, when the wind acts on the umbrella surface (the umbrella surface is supported by being connected with the main rib 95 ), together with the main rib 95 and the supporting rib 94 All bear a downward pressure, and it is very easy to make the pivot point 99 break away from the hooked position with the pivot hook 98, and even cause the decoupling of the pivot hook 98 to fall. When swinging in an unstable grip, when the supporting umbrella rib 94 occurs on the pivoting hook portion 98 that hangs down, the joint strength of the umbrella frame will lose its support balance, and using it in a windy environment will constitute a potential crisis for the user.

Therefore, the problems of connection strength and safety of umbrella ribs need to be broken through and improved.
