DETAILED DESCRIPTION

[0031] In the description of the present invention, it should be understood that the terms "one end", "the other end", "outside", "upper", "inside", "horizontal", "coaxial", "center", "end", "length", "outer end" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0032] The utility model will be further described below in conjunction with the accompanying drawings. Example

[0033] like Figure 1 and 2 As shown, an outdoor umbrella with a split umbrella opening and closing mechanism includes a column 1 and an umbrella frame 2 located on one side of the column 1. An armrest mechanism 3 is provided on the column 1. The armrest mechanism 3 can move up and down along the column 1 and lock at a specified position. An inclined rod assembly is provided on the armrest mechanism 3, and the outer end of the inclined rod assembly cooperates with the umbrella frame 2 to support the umbrella frame 2. A rod body 4 that cooperates with the inclined rod assembly is provided on the top of the column 1, which is used to limit the angle of the inclined rod assembly to reverse outward.

[0034] In this embodiment, the inner end of the tie rod body 4 is hinged to the column 1, and the outer end is connected to the diagonal tie rod assembly through a connecting piece. The outer end of the tie rod body 4 is hinged to the connecting piece. The connecting piece can slide along the length direction of the diagonal tie rod assembly and can rotate along the axial direction of the connecting piece, thereby avoiding interference of the diagonal tie rod assembly with the tie rod body 4 when rotating.

[0035] The inclined rod assembly includes an inclined rod body 5, an opening and closing umbrella mechanism 6 and a connecting seat 7. The connecting seat 7 is installed on the armrest mechanism 3. The opening and closing umbrella mechanism 6 is arranged at the end of the inclined rod body 5, and the inner end is hingedly matched with the connecting seat 7. The opening and closing umbrella mechanism 6 is used to control the expansion and folding of the umbrella frame 2.

[0036] like Figure 2 and 3 As shown, the umbrella opening and closing mechanism 6 includes a mounting base 6-1 and an umbrella opening and closing unit. The mounting base 6-1 is embedded and fixed on the inclined rod body 5, and the inner end is hingedly matched with the connecting seat 7. The mounting base 6-1 is provided with an installation chamber that communicates with the inner cavity of the inclined rod body 5. The umbrella opening and closing unit is arranged in the installation chamber.

[0037] The opening and closing umbrella unit includes an umbrella rope, a winding wheel 6-2 and an opening and closing driving rod 6-3. The opening and closing driving rod 6-3 is inserted into the mounting base 6-1 and can rotate under the drive of the crank. The winding wheel 6-2 is mounted on the opening and closing driving rod 6-3. The winding wheel 6-2 can rotate under the drive of the opening and closing driving rod 6-3, thereby realizing the winding or unwinding of the umbrella rope wound on the winding wheel 6-2. The expansion or folding of the umbrella frame 2 is controlled by winding or unwinding the umbrella rope.

[0038] Specifically, an arc-shaped driving member 6-4 for driving the winding wheel 6-2 to move is fixed to the inner end of the opening and closing driving rod 6-3. A transmission member 6-5 that cooperates with the driving member 6-4 is fixed on the inner side of the winding wheel 6-2. When the opening and closing driving rod 6-3 drives the driving member 6-4 to rotate clockwise or counterclockwise, the driving member 6-4 drives the transmission member 6-5 on the winding wheel 6-2 to rotate, thereby driving the winding wheel 6-2 to rotate synchronously, so as to achieve the winding or unwinding of the parachute rope.

[0039] Furthermore, the driving member 6-4 is provided with a torsion spring that can realize bidirectional anti-slip of the winding wheel 6-2, so that the winding wheel 6-2 can be locked when the parachute rope is wound to any length. Specifically, the two end surfaces on the driving member 6-4 for the movement of the transmission member 6-5 are respectively the first driving surface and the second driving surface. The two ends of the torsion spring are respectively against the first driving surface and the second driving surface. Furthermore, the mounting base 6-1 is provided with a mounting groove that matches the torsion spring. The torsion spring is nested in the mounting groove.

[0040] When the opening and closing driving rod 6-3 is driven to rotate by the crank, the driving member 6-4 on the opening and closing driving rod 6-3 drives the annular shape of the torsion spring to shrink, so that the friction between the torsion spring and the inner wall of the installation groove is reduced, so that the driving member 6-4 can drive the winding wheel 6-2 to rotate. When the driving member 6-4 stops rotating, the torsion spring is in a circular expansion trend under the pre-rotation force of the winding wheel 6-2, so that the friction between the torsion spring and the inner wall of the installation groove increases. The greater the force on the torsion spring, the more it expands, and the greater the friction between it and the inner wall of the installation groove, thereby achieving an anti-slip effect.

[0041] In this embodiment, the outer end of the parachute cord is connected to the umbrella frame 2. When the parachute cord is gradually rolled up, the umbrella frame 2 is gradually unfolded; when the parachute cord is gradually loosened, the umbrella frame 2 is gradually folded.

A telescopic supporting rod is arranged between the upper umbrella plate 2-2 and the lower umbrella plate 2-3. The umbrella rib structure includes an upper umbrella rib 2-4 and a lower umbrella rib 2-1. One end of the upper umbrella rib 2-4 is hingedly matched with the upper umbrella plate 2-2. One end of the lower umbrella rib 2-1 is hingedly matched with the lower umbrella plate 2-3; the other end is hingedly matched with the middle part of the upper umbrella rib 2-4.

[0043] like Figure 5 and 6 As shown, the armrest mechanism 3 includes a locking handle 3-1, an armrest seat 3-2 and an armrest control member 3-3. The armrest seat 3-2 is slidably connected to the column 1 and can slide in the vertical direction. At the same time, the armrest seat 3-2 is locked by the cooperation between the locking handle 3-1 and the column 1. Specifically, a slide groove is provided on the side of the column 1 close to the umbrella frame 2. The armrest seat 3-2 is slidably arranged in the slide groove. The armrest control member 3-3 is fixed on the armrest seat 3-2, and the staff can push the armrest control member 3-3 to push the armrest seat 3-2 to slide in the slide groove. The locking handle 3-1 is installed on the armrest control member 3-3, and can form a locking fit with the column 1 after the armrest seat 3-2 slides to the desired position.

[0044] In this embodiment, the lock handle 3-1 adopts a lock pin. A plurality of lock holes arranged in sequence are provided on the column 1. The lock pin cooperates with the latch of the corresponding lock hole to lock the position of the armrest seat 3-2. Example

[0045] An outdoor umbrella adopting a split umbrella opening and closing mechanism 6 comprises a column 1 and an umbrella frame 2 located on one side of the column 1. An armrest mechanism 3 is provided on the column 1. The armrest mechanism 3 can move up and down along the column 1 and lock at a specified position. An inclined rod assembly is provided on the armrest mechanism 3, and the outer end of the inclined rod assembly cooperates with the umbrella frame 2 to support the umbrella frame 2. A pull rod body 4 is provided on the top of the column 1 to cooperate with the inclined rod assembly.

[0046] In this embodiment, the inner end of the tie rod body 4 is hinged to the column 1, and the outer end is connected to the diagonal tie rod assembly through a connecting piece. The outer end of the tie rod body 4 is hinged to the connecting piece. The connecting piece can slide along the length direction of the diagonal tie rod assembly and can rotate along the axial direction of the connecting piece, thereby avoiding interference of the diagonal tie rod assembly with the tie rod body 4 when rotating.

[0047] The inclined rod assembly includes an inclined rod body 5, an umbrella opening and closing mechanism 6, an umbrella frame deflection mechanism and a connecting seat 7. The connecting seat 7 is installed on the armrest mechanism 3. The umbrella opening and closing mechanism 6 is arranged at the end of the inclined rod body 5, and the inner end is hingedly matched with the connecting seat 7. The umbrella opening and closing mechanism 6 is used to control the expansion and folding of the umbrella frame 2. The umbrella frame deflection mechanism is used to control the deflection direction of the umbrella frame 2.

[0048] The umbrella opening and closing mechanism 6 includes a mounting base 6-1 and an umbrella opening and closing unit. The mounting base 6-1 is embedded and fixed on the inclined rod body 5, and the inner end is hingedly matched with the connecting seat 7. The mounting base 6-1 is provided with an installation chamber that communicates with the inner cavity of the inclined rod body 5. The umbrella opening and closing unit is arranged in the installation chamber.

[0049] like Figure 7 As shown, the umbrella stand deflection mechanism includes a transmission shaft 8-1, a deflection drive wheel 8-2 and a deflection drive rod 8-3. The transmission shaft 8-1 is rotatably connected to the mounting base 6-1 through a bearing, and one end is fixed to the inclined rod body 5. The deflection drive wheel 8-2 is arranged on the transmission shaft 8-1, and can be rotated under the drive of the deflection drive rod 8-3, thereby driving the transmission shaft 8-1 to rotate.

[0050] In this embodiment, the deflection drive rod 8-3 adopts a worm. The deflection drive wheel 8-2 is provided with a tooth groove that matches the worm, thereby forming a worm gear structure. The outer end of the worm is provided with a square connection groove. A rocker is provided on the connection groove by plugging. When adjusting the deflection direction of the umbrella stand 2, the staff can drive the deflection drive wheel 8-2 to rotate by turning the rocker, and then drive the inclined rod body 5 to rotate, thereby realizing the adjustment of the deflection direction of the umbrella stand 2.

[0051] The opening and closing umbrella unit includes an umbrella rope, a winding wheel 6-2 and an opening and closing driving rod 6-3. The opening and closing driving rod 6-3 is inserted into the mounting base 6-1 and can rotate under the drive of the crank. The winding wheel 6-2 is mounted on the opening and closing driving rod 6-3. The winding wheel 6-2 can rotate under the drive of the opening and closing driving rod 6-3, thereby realizing the winding or unwinding of the umbrella rope wound on the winding wheel 6-2. The expansion or folding of the umbrella frame 2 is controlled by winding or unwinding the umbrella rope.

[0052] Specifically, an arc-shaped driving member 6-4 for driving the winding wheel 6-2 to move is fixed to the inner end of the opening and closing driving rod 6-3. A transmission member 6-5 that cooperates with the driving member 6-4 is fixed on the inner side of the winding wheel 6-2. When the opening and closing driving rod 6-3 drives the driving member 6-4 to rotate clockwise or counterclockwise, the driving member 6-4 drives the transmission member 6-5 on the winding wheel 6-2 to rotate, thereby driving the winding wheel 6-2 to rotate synchronously, so as to achieve the winding or unwinding of the parachute rope.

[0053] Furthermore, the driving member 6-4 is provided with a torsion spring (not shown in the figure) that can realize bidirectional anti-slip of the winding wheel 6-2, so that the winding wheel 6-2 can be locked when the parachute rope is wound to any length. Specifically, the two end surfaces on the driving member 6-4 for the movement of the transmission member 6-5 are the first driving surface and the second driving surface. The torsion spring is sleeved on the outer ring of the driving member 6-4, and the two ends are respectively against the first driving surface and the second driving surface. Furthermore, the mounting base 6-1 is provided with a mounting groove that matches the torsion spring. The torsion spring is nested in the mounting groove.

[0054] When the opening and closing driving rod 6-3 is driven to rotate by the crank, the driving member 6-4 on the opening and closing driving rod 6-3 drives the annular shape of the torsion spring to shrink, so that the friction between the torsion spring and the inner wall of the installation groove is reduced, so that the driving member 6-4 can drive the winding wheel 6-2 to rotate. When the driving member 6-4 stops rotating, the torsion spring is in a circular expansion trend under the pre-rotation force of the winding wheel 6-2, so that the friction between the torsion spring and the inner wall of the installation groove increases. The greater the force on the torsion spring, the more it expands, and the greater the friction between it and the inner wall of the installation groove, thereby achieving an anti-slip effect.

[0057] The armrest mechanism 3 includes a locking handle 3-1, an armrest seat 3-2 and an armrest control member 3-3. The armrest seat 3-2 is slidably connected to the column 1 and can slide in the vertical direction.
