Technical Field

[0001] This utility model relates to the technical field of umbrella steering adjustment devices, specifically an umbrella steering adjustment device. Background Technology

[0002] Traditional beach umbrellas typically consist of a long support pole inserted into the ground, from which the umbrella is then opened. While the structure is simple, adjusting the umbrella's angle of coverage is not flexible enough. Depending on the sun's position, adjusting the umbrella's angle requires pulling out the support pole and tilting it, which is not very stable.

[0003] Therefore, steering mechanisms are widely used in the umbrella industry. Existing steering mechanisms have one end connected to an umbrella pole fixed to the ground (this pole has no umbrella, only a pole), and the other end connected to an umbrella pole with an umbrella. The two ends of the steering mechanism can rotate relative to each other, thereby adjusting the umbrella angle. However, existing steering mechanisms have complex internal structures and their stability needs improvement. Therefore, this invention provides a steering adjustment device for umbrellas.

Detailed Implementation

[0027] Example 1:

[0028] Please see Figures 1-5 This utility model provides a technical solution: an umbrella steering adjustment device, including a main pole 1, a pressing part 2, a steering assembly 3, and a limiting cap 4; the pressing part 2 is disposed at one end of the main pole 1, and a limiting hole 11 is formed on the main pole 1 near the pressing part 2 for the umbrella pole to pass through, the limiting hole 11 communicating with one end of the main pole 1; the pressing part 2 restricts the movement of the umbrella pole by rotating and adjusting the size of the limiting hole 11. The limiting cap 4 is threadedly connected to the other end of the main pole 1.

[0029] The steering assembly 3 includes a fastening part 31 and a steering tube 32. The lower side of the fastening part 31 is fixedly connected to the steering tube 32, and a parachute rod for rotating direction is installed inside the steering tube 32. The fastening part 31 is fitted onto the main rod 1 near the limit cap 4. The inner diameter of the fastening part 31 is adjustable, enabling it to lock or release the main rod 1. When the fastening part 31 is locked onto the main rod 1, it cannot drive the steering tube 32 to rotate. Multiple arc-shaped protrusions are formed on the outer wall of the main rod 1 corresponding to the fastening part 31. These protrusions are distributed along the axial direction of the main rod 1 and form a locking part 12. Grooves are formed on the inner wall of the fastening part 31 corresponding to the protrusions, further locking the main rod 1. When the fastening part 31 is released from the main rod 1, the friction between the protrusions and the grooves decreases, allowing the fastening part 31 to drive the steering tube 32 to rotate.

[0030] The fastening part 31 includes a sleeve 311, a fastening arc ring 312, a fastening bolt 313, and a fastening handle 314; a groove is formed in the inner wall of the fastening arc ring 312, and the fastening arc ring 312 has a vertical side opening, with a fastening plate 3121 and a fastening arc plate 3122 extending from the upper and lower ends of the opening, respectively. The upper side of the fastening arc plate 3122 is concave to form an arc surface to form an abutment area. A through hole is provided in the middle of the fastening plate 3121 and the fastening arc plate 3122. The fastening bolt 313 passes through the through hole and extends out of the fastening arc plate 3122. The fastening handle 314 is provided on the upper side of the fastening arc plate 312, and its inner surface is concave in the middle to match the fastening arc ring 312. The middle of the end of the fastening handle 314 is hollowed out, and a rotating rod 3141 is provided in the hollowed-out part. The rotating rod 3141 passes through the fastening bolt 313 extending out of the fastening arc plate 3122, and its two ends extend to both sides to be fixedly connected to the end of the fastening handle 314, so that the fastening handle 314 and the fastening bolt 313 are rotatably connected. The end of the fastening handle 314 protrudes outward to form an abutment portion, which is arc-shaped to abut against the abutment area of ​​the fastening arc plate 3122. This causes the fastening arc plate 3122 to move closer to the fastening plate 3121, reducing the distance between the fastening plate 3121 and the fastening arc plate 3122, thereby reducing the inner diameter of the fastening arc ring 312 and locking the fastening arc ring 312 to the main rod 1 to prevent rotation. The end of the fastening arc ring 312, located on the lower side of the fastening arc plate 3122, is fixedly connected to the sleeve 311.

[0031] The main rod 1 is divided into a limiting rod 13 and a steering rod 14. The diameter of the steering rod 14 is smaller than that of the limiting rod 13, and the steering rod 14 and the limiting rod 13 are fixedly connected. A limiting hole 11 is formed in the limiting rod 13. A sleeve 311 and a fastening arc ring 312 are fitted onto the steering rod 14. A limiting cap 4 is threaded onto the steering rod 14 and fits against the end of the sleeve 311. The end of the limiting rod 13 fits against the end of the fastening arc ring 312, thereby restricting the axial movement of the fastening arc ring 312. A steering tube 32 is fixedly connected to the lower side of the sleeve 311 and the fastening arc ring 312.

[0032] The clamping part 2 includes a clamping block 21 and a drive cover 22. A drive rod 221 extends from the middle of the drive cover 22 and is threadedly connected to the end of the limiting rod 13. The clamping block 21 is disposed in the limiting hole 11 and close to the drive bolt 22, and can slide left and right within the limiting hole 11. The middle part of the end of the drive rod 221 extends further and is threadedly connected to the clamping block 21. Thus, when the drive rod 221 rotates to achieve axial movement, it drives the clamping block 21 to slide axially within the limiting hole 11, thereby adjusting the inner diameter of the limiting hole 11. The side of the clamping block 21 away from the drive cover 22 is concave into an arc surface, serving as part of the hole wall of the limiting hole 11.

[0033] Working principle: When there is no need to turn the umbrella pole, the user inserts the umbrella pole into the limiting hole 11; then rotates the drive cover 22, which drives the drive rod 221 and the pressing block 21 to move towards the umbrella pole. The pressing block 21 presses the umbrella pole, restricting the umbrella pole from sliding in the limiting hole 11.

[0034] When a turn is required, the user first rotates the fastening handle 314 away from the upper side of the fastening ring 312, so that the outer convex arc surface of the end of the fastening handle 314 does not abut against the inner concave arc surface of the fastening ring 3122; the friction between the protrusion and the groove of the locking part 12 is reduced, and the user rotates the steering tube 32 with a force greater than the friction force to the required angle, at which point the protrusion and the groove match again; then the user rotates the fastening handle 314 in the opposite direction, so that the outer convex arc surface of the end of the fastening handle 314 abuts against the inner concave arc surface of the fastening ring 3122, increasing the friction between the protrusion and the groove of the locking part 12 and preventing the fastening ring 312 from rotating; finally, the umbrella pole that needs to be turned is installed in the steering tube 32.
