Description

Technical Field

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

[0002] Hanging umbrellas are a type of parasol that provides a large shaded area, is easy to install, and can provide users with a comfortable leisure environment. They are usually used in outdoor places such as courtyards, squares, and gardens to prevent direct sunlight. There are many types of hanging umbrellas, including side-hanging umbrellas and side-poster umbrellas.

[0003] A traditional curved-arm parasol consists of a pole, a curved-arm umbrella pole, a support tube, and an umbrella canopy. To open the umbrella canopy, first lift the support tube to a fixed position, then secure the support tube to the movable seat with a fixed sleeve. The movable seat slides upward and locks onto the pole. The umbrella canopy can then be opened by cranking the rope winder.

[0004] Hand-cranked hanging umbrellas are easily damaged by prolonged exposure to sun and rain. Therefore, staff have to fold them up and place them indoors daily. However, the complex structure of hand-cranked umbrellas makes opening and closing them laborious and time-consuming, wasting considerable time and effort. Therefore, there is an urgent need to design a support structure for hand-cranked hexagonal hanging umbrellas to solve these problems. Utility Model Content

[0005] The purpose of this invention is to provide a hand-cranked hexagonal umbrella support structure to address the aforementioned shortcomings in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A hand-cranked hexagonal umbrella support structure includes a base plate, a shaft mounted in the middle of the base plate, a column rotatably fitted around the shaft, fastening components corresponding to the shaft mounted around the column, a connecting rod mounted at the upper end of the column, an iron cap mounted at the lower end of the connecting rod, an umbrella central shaft mounted below the iron cap, and a sliding sleeve slidably fitted around the umbrella central shaft.

[0008] The sliding sleeve has two symmetrically rotating and engaging arms on its periphery. An umbrella-shaped surface is installed between the iron cap and the two rotating arms. The upper end of the column and one end of the connecting rod are both rotatably engaged with pulleys. The lower end of the column is rotatably engaged with a winch. A steel rope is wound around the periphery of the winch. One end of the steel rope passes around the two pulleys in sequence and is fixed to the upper end of the sliding sleeve.

[0009] Furthermore, the connecting rod includes a hinged sleeve installed at the upper end of the column, a cantilever beam installed on one side of the hinged sleeve, and a lifting shaft installed at one end of the cantilever beam, and the iron cap is fixed to the lower end of the lifting shaft.

[0010] Furthermore, a reinforcing plate is installed at the corner of the hinged sleeve and the cantilever beam, one of the pulleys is rotatably engaged with the middle of the lifting shaft, and the other end of the steel rope is fixed to the periphery of the winch.

[0011] Furthermore, two hinged lugs are symmetrically mounted on the periphery of the sliding sleeve, one end of the two retractable arms is rotatably engaged with the two hinged lugs, and a retainer is mounted on one side of each of the two retractable arms.

[0012] Furthermore, a safety rope is installed between each of the two card holders and the iron cap, a baffle corresponding to the sliding sleeve is installed at the lower end of the umbrella central shaft, and a winch reducer is installed at the lower end of the column.

[0013] Furthermore, the output end of the winch reducer is fixed to the shaft of the winch, and a nylon rotating base is rotatably fitted around the shaft, the nylon rotating base being fixed to the lower end of the column.

[0027] like Figure 1-4 As shown in the figure, the present invention provides a hand-cranked hexagonal umbrella support structure, including a base plate 1, a shaft 2 installed in the middle of the base plate 1, a column 3 rotatably fitted around the shaft 2, fastening components corresponding to the shaft 2 installed around the column 3, a connecting rod 4 installed at the upper end of the column 3, an iron cap 5 installed at the lower end of the connecting rod 4, an umbrella central shaft 6 installed at the lower side of the iron cap 5, a sliding sleeve 7 slidably fitted around the umbrella central shaft 6, two symmetrically rotating arms 8 rotatably fitted around the sliding sleeve 7, an umbrella surface 9 installed between the iron cap 5 and the two rotating arms 8, pulleys 10 rotatably fitted at the upper end of the column 3 and one end of the connecting rod 4, a winch 11 rotatably fitted at the lower end of the column 3, a steel rope wound around the winch 11, one end of the steel rope passing over the two pulleys 10 in sequence and fixed to the upper end of the sliding sleeve 7.

[0028] In this embodiment, a base plate 1 is included, a shaft 2 is installed in the middle of the base plate 1, a column 3 is rotatably fitted around the shaft 2, and a fastening component corresponding to the shaft 2 is installed around the column 3.

[0029] Specifically, the fastening assembly includes a slot 22 at the lower end of the column 3, a screw 23 rotatably fitted in the slot 22, a hand crank 24 installed at one end of the screw 23, and a threaded groove in the slot 22. The hand crank 24 can drive the screw 23 to rotate, so that the screw 23 is threadedly fitted with the threaded groove, thereby driving one end of the screw 23 to move horizontally, so that one end of the screw 23 abuts against the periphery of the shaft 2, thereby fixing the position of the column 3.

[0030] Specifically, the screw 23 is threaded into the threaded groove, and one end of the screw 23 abuts against the circumference of the shaft 2.

[0031] In this embodiment, the upper end of the column 3 is equipped with a connecting rod 4, the lower end of the connecting rod 4 is equipped with an iron cap 5, and the lower side of the iron cap 5 is equipped with an umbrella central shaft 6.

[0032] Specifically, the connecting rod 4 includes a hinged sleeve 12 installed on the upper end of the column 3, a cantilever beam 13 installed on one side of the hinged sleeve 12, and a cap-lifting shaft 14 installed on one end of the cantilever beam 13. The iron cap 5 is fixed to the lower end of the cap-lifting shaft 14. Through the cantilever beam 13, the umbrella surface 9 can be connected to the column 3, and the umbrella surface 9 can be stably supported.

[0033] Specifically, a stiffening plate 15 is installed at the corner of the hinge sleeve 12 and the cantilever beam 13. One of its pulleys 10 is rotatably fitted to the middle of the cap lifting shaft 14, and the other end of the steel rope is fixed to the periphery of the winch 11. Through the stiffening plate 15, the load-bearing force on the umbrella surface 9 can be distributed and transmitted, effectively improving the overall stability of the connecting rod 4.

[0034] In this embodiment, a sliding sleeve 7 is slidably fitted around the central shaft 6 of the umbrella, and two retractable arms 8 are symmetrically rotated around the sliding sleeve 7. An umbrella surface 9 is installed between the iron cap 5 and the two retractable arms 8. A pulley 10 is rotatably fitted at the upper end of the column 3 and one end of the connecting rod 4.

[0035] Specifically, two hinged lugs 16 are symmetrically installed on the periphery of the sliding sleeve 7. One end of the two closing arms 8 is rotatably engaged with the two hinged lugs 16, and a card seat 17 is installed on one side of each of the two closing arms 8. The two hinged lugs 16 make the closing arms 8 more stable when they are rotatably engaged with the sliding sleeve 7, thereby better closing and opening the umbrella surface 9.

[0036] Specifically, safety ropes 18 are installed between the two card holders 17 and the iron cap 5. A baffle 19 corresponding to the sliding sleeve 7 is installed at the lower end of the umbrella central shaft 6, and a winch reducer 20 is installed at the lower end of the column 3. The two safety ropes 18 make the umbrella surface 9 open more stably.

[0037] In this embodiment, the lower end of the column 3 is rotatably fitted with a winch 11, and a steel rope is wound around the periphery of the winch 11. One end of the steel rope passes around two pulleys 10 in sequence and is fixed to the upper end of the sliding sleeve 7.

[0038] Specifically, the output end of the winch reducer 20 is fixed to the shaft of the winch 11, and the circumference of the shaft 2 is fitted with a nylon rotating base 21, which is fixed to the lower end of the column 3.

[0039] Working steps: 1. When it is necessary to close the umbrella surface 9, start the winch reducer 20. The output end of the winch reducer 20 drives the winch 11 to rotate, so that the steel rope is wound around the circumference of the winch 11 and pulls the upper end of the sliding sleeve 7. At this time, the steel rope slides around the two pulleys 10, and the sliding sleeve 7 slides around the umbrella central shaft 6 and moves towards the lower side of the iron cap 5. At this time, one end of the two closing arms 8 rotates and engages with the two hinged ear plates 16 and remains horizontal with the umbrella central shaft 6. At the same time, the two safety ropes 18 release the pull on the two closing arms 8. At this time, the two closing arms 8 drive the umbrella surface 9 to close.

[0040] 2. When the umbrella surface 9 needs to be opened, start the winch reducer 20. The output end driven by the winch reducer 20 drives the winch 11 to rotate in the opposite direction. At this time, the steel rope is wound around the circumference of the winch 11 and the pull on the sliding sleeve 7 is released. At this time, the steel rope slides in the opposite direction and engages with the circumference of the two pulleys 10. At the same time, the sliding sleeve 7 slides in the circumference of the umbrella central shaft 6 and moves towards the side closer to the baffle 19. At this time, one end of the two closing arms 8 rotates in the opposite direction with the two hinged ear plates 16 and remains perpendicular to the umbrella central shaft 6. At the same time, the two safety ropes 18 pull the two closing arms 8. At this time, the two closing arms 8 drive the umbrella surface 9 to open.

[0041] 3. When the position of the umbrella surface 9 needs to be rotated and adjusted, activate the fastening assembly. At this time, the fastening assembly will release the fixation of the column 3. Then rotate the nylon rotating base 21 to drive the column 3 and the umbrella surface 9 to rotate synchronously, thereby adjusting the position of the umbrella surface 9. When the column 3 needs to be fixed, rotate the hand crank 24 to drive the screw 23 to rotate, so that the screw 23 engages with the threaded groove, thereby driving one end of the screw 23 to move horizontally, so that one end of the screw 23 abuts against the circumference of the shaft 2, thereby fixing the position of the column 3.

[0042] The foregoing 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.
