Description

Technical Field

[0001] The utility model belongs to the technical field of fishing umbrellas, and more specifically relates to a side-limited, lift-lock type fishing umbrella steering knuckle. Background Art

[0002] Fishing umbrellas are common fishing gear, primarily used for providing shade and shelter from the rain. They feature a large canopy and a heavy upper portion. They primarily consist of a frame, a fabric, and a pole. During use, the canopy's position must be adjusted to suit weather conditions, providing shade on sunny days and shelter from the rain on rainy days. Therefore, most fishing umbrellas feature a connecting structure between the lower and upper poles, allowing them to be tilted at specific angles, thus achieving adjustable shade.

[0003] Existing accessories for controlling the angle adjustment of fishing umbrellas allow the umbrella head and the umbrella handle of the fishing umbrella to rotate along a certain axis to a specific or desired angle. Commonly used connection structures include using a universal joint to adjust the angle or using a bending structure for adjustment.

[0004] Patent document CN202323170781.2 (filing date: November 23, 2023) discloses a pressure-rod type steering knuckle for a fishing umbrella. The pressure rod is provided on the outside of a mounting sleeve, and a connecting tube is embedded in the mounting sleeve. The connecting tube can only rotate and cannot move, thereby improving the structural strength. Compared with the existing axially movable connecting tube, the invention effectively avoids structural damage caused by insufficient contact length between the connecting tube and the mounting sleeve when the connecting tube moves to switch the angle of the fishing umbrella.

[0005] However, it is locked in position by engaging the plug and the teeth with each other, and it is laborious and not quick enough to operate it by pressing the lever during use. Utility Model Content

DETAILED DESCRIPTION

[0036] Specific embodiment 1: Please refer to Figures 1-11 A side-limited lift-lock fishing umbrella steering knuckle comprises a first mounting seat 1, a second mounting seat 2 and an adjustment component 3.

[0037] The first mounting seat 1 and the second mounting seat 2 are respectively provided with a contact surface that engages with each other, and a connecting rod 36 is provided perpendicular to and passes through the contact surface. The connecting rod 36 is respectively connected to the first mounting seat 1 and the second mounting seat 2, and a locking nut 37 is provided at one end of the connecting rod 36.

[0038] The first mounting base 1 includes a retaining groove 11, a first ear portion 12, and a first tooth portion 13. The first ear portion 12 defines a first mounting hole 14. The first teeth 13 are fixedly mounted on the side of the first ear portion 12 and are evenly distributed around the first mounting hole 14. The retaining groove 11 is formed on the side of the first ear portion 12, and symmetrically defines inwardly recessed pull-out grooves 15 on either side of the retaining groove 11.

[0039] The second mounting base 2 includes a second ear portion 21 and a second tooth portion 22. A second mounting hole 23 is defined in the second ear portion 21. The second tooth portions 22 are fixedly mounted on a side surface of the second ear portion 21 and are evenly distributed around the second mounting hole 23. The second mounting base 2 also includes a rotation slot. The rotation slot is defined on the side surface opposite the second tooth portion 22, and a locking nut 37 is positioned within the rotation slot.

[0040] In this embodiment, the two facing contact surfaces are the first tooth portion 13 and the second tooth portion 22 , and the first tooth portion 13 and the second tooth portion 22 can mesh with each other.

[0041] The adjustment assembly 3 includes an adjustment rod 31 and an adjustment plate 33. The adjustment plate 33 is nested at the other end of a connecting rod 36, which extends beyond the adjustment plate 33. One end of the adjustment rod 31 is axially rotatably connected to the extension of the connecting rod 36. The adjustment rod 31 is embedded in the retaining groove 11 of the first mounting seat 1 to limit radial rotation of the adjustment rod 31. A protrusion is provided at one end of the adjustment rod 31, which rotatably abuts against the adjustment plate 33, thereby ensuring that the contact surfaces of the first mounting seat 1 and the second mounting seat 2 are in contact with each other.

[0042] One end of the first mounting base 1 defines a placement slot, into which an adjustment plate 33 is inserted. The adjustment plate 33 includes an adjustment hole 34 and an adjustment slot 35. The adjustment hole 34 extends coaxially through the center of the adjustment plate 33. The adjustment slots 35 are symmetrically located on either side of the adjustment hole 34 and are recessed inward.

[0043] The connecting rod 36 includes a connecting portion and a threaded portion, which are respectively provided at both ends of the connecting rod 36. The threaded portion is threadedly connected to the first mounting seat 1 and the second mounting seat 2, and the outermost end of the threaded portion is connected to the locking nut 37.

[0044] It should be noted that if Figure 8 and Figure 10 As shown, in this embodiment, the rotation range of the adjusting rod 31 is 0~90°. When the adjusting rod 31 does not rotate, it is located in the limiting groove 11 and can only rotate outward; after it rotates 90°, it reaches the extreme position, and its end abuts against the inner wall of the limiting groove 11 to limit its rotation.

[0045] In the locked state, the locking nut 37 is tightened with the connecting rod 36; in the rotating state, the locking nut 37 and the connecting rod 36 are loosened so that the contact surfaces of the first mounting seat 1 and the second mounting seat 2 can be separated from each other.

[0046] A notch is provided on one end of the adjusting rod 31, and the connecting portion of the connecting rod 36 is embedded in the notch. The pin 32 is arranged to penetrate the connecting rod 36 and the adjusting rod 31 horizontally so that the adjusting rod 31 can rotate around the axis of the pin 32.

[0047] In this embodiment, the first mounting seat 1 is further provided with an axis groove 16 . The axis grooves 16 are symmetrically arranged on both sides of the adjustment rod 31 , and both ends of the pin 32 are located in the axis grooves 16 respectively.

[0048] In the locked state, the contact surfaces of the first mounting seat 1 and the second mounting seat 2 are engaged with each other to maintain a non-rotational connection between the two; in the rotating state, the contact surfaces of the first mounting seat 1 and the second mounting seat 2 are separated from each other to maintain a rotational connection between the two.

[0049] Working principle:

[0050] When the angle of the fishing umbrella needs to be adjusted, the adjusting rod 31 is rotated outward and the adjusting rod 31 is rotated to 90 degrees. The outer protrusion at the end of the adjusting rod 31 is misaligned with the adjusting groove 35 on the adjusting plate 33. The adjusting plate 33 loses the pressure applied by the adjusting rod 31, and the contact surfaces of the first mounting seat 1 and the second mounting seat 2 are separated from each other. After the second mounting seat 2 is rotated, the rotation angle of the fishing umbrella can be adjusted. After the adjustment is completed, the adjusting rod 31 is reset and pressure is applied to the adjusting plate 33, so that the contact surfaces of the first mounting seat 1 and the second mounting seat 2 are re-engaged and plugged into each other to return to the locked state. The angle can also be adjusted without using the adjusting rod 31. The locking nut 37 is loosened, and the locking nut 37 and the connecting rod 36 are loosened so that the contact surfaces of the first mounting seat 1 and the second mounting seat 2 can be separated from each other, and the rotation angle of the fishing umbrella can be adjusted. After the adjustment is completed, the locking nut 37 is tightened to return to the locked state.
