Description

Technical Field

[0001] This utility model relates to the field of fishing gear, specifically to a mechanical arm structure for adjusting a fishing umbrella. Background Technology

[0002] Currently, most fishing umbrella robotic arms on the market use simple fasteners, bolts, and springs for fixing, which have some drawbacks. For example, they are prone to loosening in strong winds or after frequent adjustments, causing the fishing umbrella to tip over; the robotic arm is prone to gear breakage due to insufficient contact points for the fixing gears; the operation is cumbersome; and the unreasonable structure leads to easy wear and tear after long-term use. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a fishing umbrella press-adjustment robotic arm structure, which solves the problems of existing fishing umbrella adjustment robotic arms being laborious, cumbersome, and having poor wind resistance.

[0004] The technical solution adopted by this utility model to achieve the above objectives is as follows:

[0005] A fishing umbrella-style adjustable mechanical arm structure includes a first link and a second link, which are movably connected to each other via a press-adjustable rotating shaft device. The press-adjustable rotating shaft device includes a button, a rotating shaft fixedly connected to the button, a return spring and a rotating shaft seat connected to the rotating shaft, and a limiting tooth on the outer periphery of the rotating shaft. The end of the first link has a first rotating arm extending axially, and a first shaft hole is provided on the first rotating arm. The end of the second link has a second rotating arm and a third rotating arm extending axially, with the second and third rotating arms spaced apart, such that a first rotating arm can be formed between the second and third rotating arms. The first rotating arm has a notch, and the second and third rotating arms are respectively provided with a second shaft hole and a third shaft hole. The first rotating arm is located at the notch of the first rotating arm, and the first shaft hole, the second shaft hole and the third shaft hole are coaxially arranged. The pressing and adjusting rotating shaft device passes through the first shaft hole, the second shaft hole and the third shaft hole and is connected to the first connecting rod and the second connecting rod. One end of the rotating shaft is located in the second shaft hole. The inner walls of the first shaft hole and the second shaft hole are provided with limiting grooves that cooperate with the limiting teeth. By pressing the button, the rotating shaft moves back and forth along the axial direction to adjust whether the end of the rotating shaft is located in the second shaft hole, thereby allowing the first connecting rod and the second connecting rod to rotate and be limited and fixed.

[0006] The rotating shaft seat is located inside the third shaft hole, and one end extends outward from the third shaft hole; the rotating shaft seat is fixed inside the third shaft hole by threads.

[0007] The rotating shaft seat has an opening at the end that mates with the return spring, and a return spring groove is provided inward along the opening. One end of the return spring is located in the return spring groove, and the other end abuts against the rotating shaft.

[0008] The rotating shaft and the button connection end are provided with a button connection shaft, and the button is fixed to the end of the button connection shaft by a threaded structure.

[0009] The diameter of the button connecting shaft is smaller than the diameter of the rotating shaft.

[0010] The limiting groove on the inner wall of the second shaft hole is provided at the end that mates with the rotating shaft. The end of the second shaft hole that mates with the button is a circular hole, and the connection between the circular hole and the limiting groove forms a rotating shaft limiting barrier.

[0011] The beneficial effects of this utility model are as follows: By employing a multi-stage meshing mechanism with rotating shaft gears, this utility model effectively solves the problems of easy swaying when the fishing umbrella is mounted and the mechanical arm being prone to gear breakage in strong winds. The use of a press-and-slide rotating shaft structure allows for convenient adjustment and structural stability. The threaded fit and tight meshing between the teeth further enhance the fixing effect, significantly improving reliability and ease of operation. Attached Figure Description

[0023] Example: See Figures 1 to 5This embodiment provides a fishing umbrella press-adjustable mechanical arm structure, which includes a first connecting rod 1 and a second connecting rod 2. The first connecting rod 1 and the second connecting rod 2 are movably connected to each other through a press-adjustable rotating shaft device. The press-adjustable rotating shaft device includes a button 3, a rotating shaft 4 fixedly connected to the button 3, a return spring 5 and a rotating shaft seat 6 connected to the rotating shaft 4, and a limiting tooth 7 is provided on the outer periphery of the rotating shaft 4. The end of the first connecting rod 1 is provided with a first rotating arm 8 extending axially, and a first shaft hole 9 is provided on the first rotating arm 8. The end of the second connecting rod 2 is provided with a second rotating arm 10 and a third rotating arm 11 extending axially, and the second rotating arm 10 and the third rotating arm 11 are spaced apart, so that a first rotating arm receiving gap is formed between the second rotating arm 10 and the third rotating arm 11. The first rotating arm 8 is located at the notch 12 of the first rotating arm, and the second rotating arm 10 and the third rotating arm 11 are respectively provided with a second shaft hole 13 and a third shaft hole 14. The first rotating arm 8 is located at the notch 12 of the first rotating arm, and the first shaft hole 9, the second shaft hole 13 and the third shaft hole 14 are coaxially arranged. The pressing and adjusting rotating shaft device passes through the first shaft hole 9, the second shaft hole 13 and the third shaft hole 14 and is connected to the first connecting rod 1 and the second connecting rod 2. One end of the rotating shaft 4 is located in the second shaft hole 13. The inner wall of the first shaft hole 9 and the inner wall of the second shaft hole 13 are provided with a limiting groove 15 that cooperates with the limiting tooth 7. By pressing the button 3, the rotating shaft 4 moves back and forth along the axial direction to adjust whether the end of the rotating shaft 4 is located in the second shaft hole 13, thereby making the first connecting rod 1 and the second connecting rod 2 rotate and be limited and fixed.

[0024] The rotating shaft seat 6 is located inside the third shaft hole 14, and one end extends outward from the third shaft hole 14; the rotating shaft seat 6 is fixed inside the third shaft hole 14 by threads.

[0025] The rotating shaft seat 6 has an opening at the end that mates with the return spring 5, and a return spring groove is provided inward along the opening. One end of the return spring 5 is located in the return spring groove, and the other end abuts against the rotating shaft 4.

[0026] The rotating shaft 4 and the button 3 are connected by a button connecting shaft 16, and the button 3 is fixed to the end of the button connecting shaft 16 by a threaded structure.

[0027] The diameter of the button connecting shaft 16 is smaller than the diameter of the rotating shaft 4.

[0028] The limiting groove 15 on the inner wall of the second shaft hole 14 is provided at the end that mates with the rotating shaft 4. The end of the second shaft hole 14 that mates with the button is a circular hole 17, and the connection between the circular hole 17 and the limiting groove 15 forms a rotating shaft limiting barrier 18.

[0029] The working principle of the fishing umbrella press-adjustment robotic arm structure in this embodiment is as follows: The upper umbrella rod of the fishing umbrella is installed on the first connecting rod, and the lower umbrella rod is installed on the second connecting rod. Pressing the button causes the rotating shaft to move in the direction of the rotating shaft seat, causing the rotating shaft to disengage from the second shaft hole. At this time, the return spring is compressed. Since the rotating shaft is disengaged from the second shaft hole, the first connecting rod can rotate relative to the second connecting rod, thereby adjusting the direction of the upper umbrella rod. When the adjustment is in the appropriate position, the button is released. Under the action of the return spring, the rotating shaft and the button move towards the second shaft hole, causing the end of the rotating shaft to re-enter the second shaft hole and engage with the limiting groove in the second shaft hole, thereby locking the first connecting rod and the second connecting rod, completing the adjustment.

[0030] However, the above description is only a preferred embodiment of the present utility model and is not intended to limit the patent scope of the present utility model. Therefore, all other embodiments described in the present utility model and the equivalent changes made thereto are included within the protection scope of the present utility model.
