Description

Technical Field

[0001] This utility model relates to the technical field of sunshade umbrella structures, and in particular to a folding umbrella structure. Background Technology

[0002] Sun umbrellas are primarily used outdoors to provide shade. However, most current sun umbrellas have non-foldable ribs, such as the sun umbrella with Chinese invention patent publication number CN116138557A. This results in a relatively long length when folded, making them inconvenient to carry and requiring bulky packaging. To address these issues, a sun umbrella structure with foldable ribs has been developed, such as the folding umbrella with Chinese utility model patent publication number CN209518401U. While this folding umbrella structure can fold, the top center is too flat when open, resulting in poor aesthetics. Furthermore, the center of the canopy dips when open, causing water to accumulate in the dip during rain, increasing the umbrella's weight and potentially leading to imbalances. This results in poor stability, especially when used as a large sun umbrella, posing a tipping safety hazard. Therefore, improvements are urgently needed. Utility Model Content

[0071] The aforementioned first hinge slot 21 and second hinge slot 51 make it easier for the corresponding connecting rods to be hinged, and the structural design is reasonable.

[0072] In this embodiment, a first hinge joint 46 is fixed to one end of the third link 43. The first hinge joint 46 extends radially along the third link 43 and is hinged to the middle position of the second link 42. The first hinge joint 46 is made of plastic material, and the third link 43 is a hollow tube. Therefore, the fixing part of the first hinge joint 46 is interference-fitted and fixed at one end of the third link 43.

[0073] Both ends of the fifth link 45 are fixed with second hinge joints 47. The second hinge joints 47 extend radially along the fifth link 45 and the two second hinge joints 47 extend in the same direction. One second hinge joint 47 is hinged to the other end of the second link 42, and the other second hinge joint 47 is hinged to the second movable part 3. The second hinge joints 47 are made of plastic material. The fifth link 45 is a hollow tube. Therefore, the fixing part of the second hinge joint 47 is interference-fitted and fixed at the end of the third link 43.

[0074] The arrangement of the first hinge joint 46 and the second hinge joint 47 ensures that the folding member 4 will not interfere with the folding and unfolding, and that the tilt angles of the fourth link 44 and the fifth link 45 meet the requirements after unfolding.

[0075] In this embodiment, the device also includes a box body 6, a hand crank 7, and a winding shaft 23 disposed within the cavity 61 of the box body 6. A first through hole 111 and a second through hole 112 are respectively provided at both ends of the rod body 1. The box body 6 is mounted on the rod body 1 at the position with the first through hole 111. The rotation shaft 71 of the hand crank 7 passes through the mounting hole 35 of the box body 6, so that at least part of the rotation shaft 71 of the hand crank 7 is placed within the cavity 61 of the box body 6. The rod body 1 is hollow to form a passageway 100 along the length of the rod body 1. The winding shaft 23 is rotatably mounted at the position of the second through hole 112. The winding shaft 23 is fixedly connected to the portion of the rotation shaft 71 of the hand crank 7 located within the cavity 61 of the box body 6. A traction rope 17 is wound around the first movable part 2 after passing through the first through hole 111 via the passage 100. The box body 6 is made of plastic and is sleeved and fixed on the rod body 1. The hand crank 7 is made of metal, and a gear 24 is sleeved and fixed on the part of the rotating shaft 71 of the hand crank 7 placed in the cavity 61 of the box body 6. A pawl 25 is installed in the cavity of the box body 6 by a spring. The pawl 25 and the gear 24 are engaged. The spring 251 used to install the pawl 25 has a spring force greater than the weight of the first movable part 2 (with a counterweight). Therefore, the traction rope winding and unwinding mechanism adopts a sunshade hand crank shaft structure with Chinese patent announcement number CN220937058U. The traction rope 17 can be a nylon rope. Therefore, when the folding component 4 is unfolded, the hand crank 7 is driven by the user to rotate forward, thereby driving the gear 24 and the winding shaft 23 to rotate forward. At this time, the rotation of the gear 24 can overcome the elastic force of the spring 251 at the pawl 25, and wind the traction rope 17 through the winding shaft 23, thereby causing the first movable part 2 to rise along the length of the rod 1. When the first movable part 2 rises to abut against the limiting protrusion 22 of the rod 1, the folding component 4 is in the first unfolded state, the umbrella cloth 8 is opened, and the hand crank 7 needs to be folded. When folding, the hand crank 7 is driven by the user to rotate in the opposite direction, thereby driving the gear 24 and the winding shaft 23 to rotate in the opposite direction. At this time, the rotation of the gear 24 overcomes the spring force at the pawl 25, and the arc-shaped pawl part of the pawl 25 can pass over the tooth groove of the gear 24, so that the winding shaft 23 releases the traction rope 17, thereby causing the first movable part 2 to descend along the length direction of the rod 1 under its own gravity. When the first movable part 2 descends to near the box 6, the folding component 4 is in the second folded state, and the umbrella cloth 8 is gathered.

[0076] Preferably, a roller 16 is rotatably installed inside the second perforation 112, and the outer peripheral surface of the roller 16 is supported by the traction rope 17. The setting of the roller 16 makes the movement of the traction rope 17 smoother and avoids jamming.

[0077] Preferably, the limiting protrusion 22 is fixed on the rod body 1 by bolts, and the limiting protrusion 22 is made of rubber.

The locking rod 150 is provided in the locking channel 143, and a locking block 151 adapted to the locking groove 133 is provided on the locking rod 150. The first steering knuckle 13 and the second steering knuckle 14 rotate relative to each other via a hinge axis 201 that hinges the hinge body 131 to the hinge space 141, causing the locking tooth portion 132 to rotate around the hinge axis that hinges the hinge body 131 to the hinge space 141. Multiple locking grooves 133 are located on the rotational trajectory of the locking tooth portion 132 and are spaced apart from each other. A return spring 19 is provided in the positioning channel 18, with both ends of the return spring 19 abutting against the push plate 152 at the outer end of the locking rod 150 and the end wall of the positioning channel 18, respectively. This structural arrangement ensures that when the second rod portion 12 is fixed... By pressing the button 152, the locking rod 150 moves along the length of the locking channel 143, causing the locking block 151 to disengage from the locking groove 133. At this time, the first rod 11 rotates around the hinge center where the hinge body 131 and the hinge space 141 are hinged to each other, so that the first rod 11 is tilted to change the orientation of the unfolded folding umbrella and achieve the same effect at other angles. At this time, the force applied to the button 152 is driven, and the locking rod 150 is reset under the action of the return spring 19, causing the locking block 151 to be inserted into the locking groove 133 to position the adjusted angle.

[0079] Preferably, the second rod portion 12 includes a first segment 121 and a second segment 122. The first segment 121 and the second segment 122 are interlocked and fixed together by a spring pin 123 inserted into a pin hole 124.
