Description

Technical Field

[0001] This utility model relates to the field of parasol technology, specifically to a hand-cranked hexagonal hanging umbrella. Background Technology

[0002] Hand-cranked hexagonal hanging umbrellas are widely used in outdoor leisure venues, commercial pedestrian streets, and courtyard landscapes due to their unique suspension structure and flexible space utilization. These umbrellas are opened and closed manually, and are more cost-effective and environmentally adaptable than electric products.

[0003] Traditional hand-cranked hanging umbrellas often employ simple rope winding or gear transmission structures, lacking professional speed reduction devices to increase torque. Manual operation requires overcoming significant resistance, making it difficult for women or elderly users to operate independently, and potentially leading to rope breakage or hand sprains due to excessive force. Furthermore, traditional hanging umbrellas are typically fixed to the top of a support pole, making it impossible to adjust the shading angle and direction. When the direction of sunlight changes, users must reposition the entire umbrella unit, a cumbersome operation that can damage the ground. In complex spaces such as courtyards and terraces, the fixed shading range is insufficient to meet the shading needs of different areas and at different times. Therefore, there is an urgent need to design a hand-cranked hexagonal hanging umbrella to solve these problems. Utility Model Content

A winding winch 23 is provided on one side of the winch reducer 21. The surface of the winding winch 23 has a spiral guide groove, which, together with the anti-jumping baffle, ensures that the wire rope 4 is neatly arranged and avoids tangling. The rotating gear of the winch reducer 21 is connected to a drive shaft 24, and the other end of the drive shaft 24 is connected to the winding winch 23. The force is transmitted between the winch reducer 21 and the winding winch 23 through the drive shaft 24. A crank handle 22 is provided on one side of the winch reducer 21. The crank handle 22 adopts an ergonomic D-shaped grip and is covered with TPE anti-slip material. The crank handle 22 is located on the outer wall of the support rod 1.

[0025] In this embodiment, a rotating mechanism 3 is provided at the top of the plug rod 61. The rotating mechanism 3 includes a rotating shaft 31, which is forged from alloy steel. The rotating shaft 31 is welded to the top of the plug rod 61 and is inserted into the support rod 1. A bearing 32 is sleeved on the outer wall of the rotating shaft 31. The bearing 32 is a double-row angular contact ball bearing. A rotating base 33 is provided on the upper surface of the bearing 32. The rotating base 33 provides support and lubrication for the support rod 1, making the support rod 1 more stable and smooth during rotation. The rotating base 33 is sleeved on the rotating shaft 31. The upper surface of the rotating base 33 is in contact with the support plate inside the support column 1. A fixed crank 34 is provided on one side of the outer wall of the support rod 1. The fixed crank 34 is bolted to the support rod 1. The fixed crank 34 is used to limit and fix the support rod 1 by rotating the bolt.

[0026] In this embodiment, a plug-in rod 61 is provided on the base 6, one end of the support rod 1 is plugged into the plug-in rod 61, a cantilever 13 is provided at one end of the support rod 1, and an umbrella central shaft 8 is provided at one end of the cantilever 13. A steel wire rope 4 is provided inside the support rod 1 and the umbrella central shaft 8. The steel wire rope 4 is a 1×19 strand stainless steel wire rope 4. One end of the steel wire rope 4 is fixed on the winding winch 23. Guide rollers 5 are provided at both the upper and lower ends of the umbrella central shaft 8, and the guide rollers 5 are also provided inside the support rod 1. The guide rollers 5 are made of composite material wheel body, and the wheel groove arc is precisely matched with the diameter of the steel wire rope 4. The steel wire rope 4 is wound on the outer wall of the guide roller 5.

[0027] In this embodiment, a sliding sleeve 9 is slidably sleeved on the outer wall of the umbrella central shaft 8. A self-lubricating copper sleeve is embedded inside the sliding sleeve 9 to reduce the sliding resistance with the umbrella central shaft 8. A fixing buckle 91 is provided at the upper end of the sliding sleeve 9. The fixing buckle 91 is a simple bolt-type fixing buckle. The other end of the steel wire rope 4 is fixed on the fixing buckle 91.

[0028] In this embodiment, a hanging umbrella 7 is provided on the central axis 8 of the umbrella. The hanging umbrella 7 includes several retractable arms 73. The retractable arms 73 are rotatably connected to the outer wall of the sliding sleeve 9. When the sliding sleeve 9 slides downward, the retractable arms 73 unfold under the action of the limiting rope 71. A cantilever hanging plate 72 is provided on the upper outer wall of the central axis 8. The cantilever hanging plate 72 is fixed to the central axis 8 by bolts. The limiting rope 71 and the umbrella fabric are fixed to the cantilever hanging plate 72 by bolts. One end of the limiting rope 71 is fixed to the retractable arm 73 by bolts.

[0029] Working steps: 1. Fix the base 6 to the installation position, insert the bottom of the support rod 1 into the connector rod 61 to ensure the overall structure is stable, then hold the handle 22 and rotate it clockwise. The handle 22 drives the rotating gear in the winch reducer 21 to rotate, and uses the speed reduction and torque increase characteristics of the worm gear drive to transmit power to the transmission shaft 24. The transmission shaft 24 drives the winding winch 23 to rotate synchronously and begin winding the wire rope 4. As the wire rope 4 is continuously wound, the sliding sleeve 9 slides down along the umbrella central axis 8, pulling the winding arm 73, which is rotatably connected to the sliding sleeve 9, to gradually unfold until the umbrella 7 is fully unfolded.

[0030] 2. If it is necessary to adjust the position of the hanging umbrella 7, first loosen the fixing of the rotating base 33 by rotating the fixing handle 34, and use the smooth rotation of the bearing 32 to rotate the support rod 1 and the hanging umbrella 7 to the desired sunshade direction. Then tighten the fixing handle 34 to fix the support rod 1 and keep the hanging umbrella 7 in the target position.

[0031] 3. When it is necessary to retract the parachute 7, hold the crank 22 and turn it counterclockwise. The winch reducer 21 drives the winding winch 23 to rotate in the opposite direction, releasing the wire rope 4. Under the action of the parachute 7's own weight and the structural characteristics of the retracting arm 73, the sliding sleeve 9 slides upward along the central axis 8 of the parachute, and the retracting arm 73 gradually retracts until the parachute 7 is completely retracted.

[0032] The above description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
