[0026] The present invention will be further described below in conjunction with the accompanying drawings.

[0027] like Figure 1As shown, an outdoor parasol with an umbrella column lifting structure includes an umbrella column base 1, an umbrella column assembly 2, an umbrella frame assembly and an armrest shell assembly 4. The umbrella column assembly 2 is fixed to the umbrella column base 1. The armrest shell assembly 4 is slidably connected to the umbrella column assembly 2 and can be locked at any position to control the opening and closing of the umbrella frame assembly. The umbrella frame assembly includes a cantilever assembly 5 and an umbrella frame assembly 3.

[0028] The cantilever assembly 5 includes a cantilever body 5-1, a connecting rod body 6 and an umbrella deflection assembly 5-2. The umbrella frame assembly 3 is installed at the outer end of the cantilever body 5-1. The inner end of the cantilever body 5-1 is hingedly arranged on the armrest shell assembly 4 through the umbrella deflection assembly 5-2, and can rotate around the axis driven by the umbrella deflection assembly 5-2. The inner end of the connecting rod body 6 is hinged to the top of the umbrella column assembly 2, and the outer end is connected to the cantilever body 5-1 to support the rotating cantilever body 5-1.

[0029] Specific structure such as Figure 1 and 2 As shown, the outer end of the connecting rod body 6 is connected to the cantilever body 5-1 through the tube set 7. The outer end of the connecting rod body 6 is hinged to the tube set 7. The cantilever body 5-1 passes through the inner ring of the tube set 7, and can rotate around the axis of the tube set 7 and slide along the axial direction of the tube set 7. The setting of the connecting rod body 6 can ensure that the cantilever body 5-1 is supported while avoiding interference with the rotation of the cantilever body 5-1.

[0030] like Figure 2 and 3 As shown, the umbrella column assembly 2 includes an upper umbrella column 2-1 and a lower umbrella column 2-2. The lower umbrella column 2-2 is fixed on the umbrella column base 1 and is a hollow shell structure. The upper umbrella column 2-1 and the lower umbrella column 2-2 are slidably matched, and a lifting adjustment mechanism 2-3 is arranged between them. The staff can drive the lifting adjustment mechanism 2-3 to realize the rise or fall of the upper umbrella column 2-1 relative to the lower umbrella column 2-2, and can lock it at any height, thereby realizing the lifting and lowering adjustment of the umbrella frame assembly 3 in the height direction, and avoiding the interference of external objects such as tree branches when the umbrella frame assembly 3 is unfolded.

[0031] like Figure 3-6As shown, the lifting and adjusting mechanism 2-3 includes an adjusting component and a lifting and driving component. The adjusting component includes a mounting base 2-3-1, a screw rod 2-3-2 and a receiving member 2-3-3. Among them, the mounting base 2-3-1 is fixed on the upper umbrella column 2-1. The screw rod 2-3-2 is rotatably connected to the mounting base 2-3-1 and can rotate under the drive of the lifting and driving component. The receiving member 2-3-3 is fixed at the port of the lower umbrella column 2-2 and is provided with a threaded hole that matches the screw rod 2-3-2. The tail end of the screw rod 2-3-2 passes through the threaded hole and is threadedly matched with the threaded hole. When the screw rod 2-3-2 rotates under the drive of the lifting and driving component, it will push the upper umbrella column 2-1 to move upward or downward with the cooperation of the receiving member 2-3-3, thereby realizing the lifting and lowering operation of the upper umbrella column 2-1.

[0032] like Figure 4 and 5 As shown, the lifting drive assembly includes a transmission rod 2-3-4, a connecting piece 2-3-5, and a first bevel gear 2-3-6 and a second bevel gear 2-3-7 that mesh with each other. Among them, the transmission rod 2-3-4 is rotatably connected to the upper umbrella column 2-1, and the outer end is exposed. A square socket is provided on the transmission rod 2-3-4. The staff can drive the rotation of the transmission rod 2-3-4 by inserting the plug rod into the socket. The first bevel gear 2-3-6 is fixed to the inner end of the transmission rod 2-3-4. The second bevel gear 2-3-7 is fixed to the top of the screw 2-3-2 through the connecting piece 2-3-5. When the transmission rod 2-3-4 rotates, the staff will drive the screw 2-3-2 to rotate synchronously, thereby realizing the lifting and lowering operation of the upper umbrella column 2-1.

[0033] In this embodiment, the screw rod 2-3-2 is fixed to the connector 2-3-5 by screws. A bearing (not shown) is fixed to the outer ring of the connector 2-3-5. A stepped groove 2-4 matching the bearing is provided on the mounting base 2-3-1. The bearing is embedded and fixed in the stepped groove 2-4, thereby realizing the rotational cooperation between the connector 2-3-5 and the mounting base 2-3-1.

[0034] Furthermore, two limiters 2-5 are fixed to the outer ring of the connecting member 2-3-5. The two limiters 2-5 are arranged at intervals to limit the position of the connecting member 2-3-5 relative to the mounting base 2-3-1, so as to prevent the upper umbrella column 2-1 from being unable to complete the lifting operation due to the movement of the connecting member 2-3-5.

[0035] Furthermore, a stabilizing member is installed at the tail end of the screw rod 2-3-2. The stabilizing member is slidably matched with the lower umbrella column 2-2. A mounting hole is provided on the stabilizing member to match the tail end of the screw rod 2-3-2. The tail end of the screw rod 2-3-2 is rotatably connected in the mounting hole. When the screw rod 2-3-2 is rising or falling, the tail end is limited by the stabilizing member, thereby ensuring the stability of the rising and falling of the screw rod 2-3-2.

[0036] like Figure 4 As shown, the armrest shell assembly 4 includes an armrest shell body 4-1 and a locking assembly 4-2. The armrest shell body 4-1 is slidably connected to the upper umbrella column 2-1, and can be locked at any position by the locking assembly 4-2. An umbrella rope retracting assembly 8 is provided on the armrest shell body 4-1. An umbrella rope connected to the umbrella rope retracting assembly 8 is provided on the umbrella frame assembly 3. The umbrella rope retracting assembly 8 is used to reel in or release the umbrella rope, thereby realizing the folding or opening of the umbrella frame assembly 3.

[0037] like Figure 7 As shown, the umbrella rope retracting and releasing assembly 8 includes a transmission shaft 8-1, a rope winding wheel 8-2 and a crank handle 8-3. Among them, the transmission shaft 8-1 is rotatably connected in the inner cavity of the armrest shell body 4-1, and a first socket matching the crank handle 8-3 is opened at the outer end. The inner end of the crank handle 8-3 can be plugged into the first socket, and power is input to drive the transmission shaft 8-1 to rotate. The rope winding wheel 8-2 is fixed on the transmission shaft 8-1, and can rotate synchronously when the transmission shaft 8-1 rotates, thereby realizing the winding or release of the umbrella rope. Furthermore, a two-way non-slip torsion spring is arranged between the rope winding wheel 8-2 and the armrest shell body 4-1, which can lock its rotation angle after the rope winding wheel 8-2 rotates to prevent further release of the umbrella rope.

[0038] like Figure 3 and 4 As shown, the locking assembly 4-2 includes a driving member 4-2-1 and a locking pin 4-2-2. Among them, the driving member 4-2-1 is slidably connected to the armrest shell body 4-1, and can switch between being close to or away from the upper umbrella column 2-1. The locking pin 4-2-2 is fixed to the top of the driving member 4-2-1. A locking member 4-3 that cooperates with the locking pin 4-2-2 is fixed on the upper umbrella column 2-1. A serrated groove is provided on the outer surface of the locking member 4-3. In the initial state, the end of the locking pin 4-2-2 is clamped in the groove. When the locking pin 4-2-2 moves to the side away from the locking member 4-3 under the drive of the driving member 4-2-1, the locking pin 4-2-2 disengages from the groove, so that the armrest shell body 4-1 can slide on the upper umbrella column 2-1. When the armrest shell body 4-1 slides to the desired position, the locking pin 4-2-2 moves toward the locking member 4-3 under the drive of the driving member 4-2-1, and is gradually inserted into the corresponding position of the card slot, thereby locking the position of the armrest shell body 4-1.

[0039] In this embodiment, a return spring is installed in the armrest shell body 4-1. The outer end of the return spring abuts against the driving member 4-2-1, which can provide elastic power for the driving member 4-2-1 to move outward. When the user presses the driving member 4-2-1 inward, the driving member 4-2-1 will drive the locking pin 4-2-2 away from the locking member 4-3, and the return spring is compressed. When the user releases the pressure applied to the driving member 4-2-1, the return spring provides elastic power for the driving member 4-2-1 to move outward, and the locking pin 4-2-2 is gradually inserted into the slot on the locking member 4-3 under the drive of the driving member 4-2-1, thereby achieving the locking of the armrest shell body 4-1.

[0040] like Figure 7 As shown, the canopy deflection assembly 5-2 includes a rotating sleeve 5-2-1, and a worm gear 5-2-2 and a worm 5-2-3 that cooperate with each other. The rotating sleeve 5-2-1 is hingedly arranged on the armrest shell body 4-1. The worm 5-2-3 is rotatably connected to the support seat. The worm gear 5-2-2 is fixed to the inner end of the cantilever body 5-1, and can rotate synchronously when the worm 5-2-3 rotates, thereby driving the rotation of the cantilever body 5-1.

[0041] In this embodiment, a second socket that matches the crank handle 8-3 is provided at the end. When the end of the crank handle 8-3 is inserted into the second socket, the worm 5-2-3 can be driven to rotate by rotating the crank handle 8-3, and the rotation adjustment of the cantilever body 5-1 can be achieved through the cooperation between the worm 5-2-3 and the worm wheel 5-2-2.

[0042] like Figure 1 and 8 As shown, the umbrella frame assembly 3 includes an upper umbrella disc body 3-1, a lower umbrella disc body 3-2, and a plurality of umbrella rib structures 3-3 arranged on the upper umbrella disc body 3-1 and the lower umbrella disc body 3-2. Among them, the upper umbrella disc body 3-1 is hingedly matched with the outer end of the cantilever body 5-1. The outer end of the umbrella rope on the rope winding wheel 8-2 is connected to the lower umbrella disc body 3-2. When the rope winding wheel 8-2 reels the umbrella rope, it drives the lower umbrella disc body 3-2 to move closer to the upper umbrella disc side, and the umbrella frame assembly 3 switches to the unfolded state. When the rope winding wheel 8-2 releases the umbrella rope, the lower umbrella disc body 3-2 moves downward under the action of gravity, away from the upper umbrella disc body 3-1, and the umbrella frame assembly 3 switches to the folded state.

[0043] like Figure 8As shown, the upper umbrella plate body 3-1 has an umbrella plate part at the top and a plug-in part at the bottom. A slot that matches the plug-in part is provided on the lower umbrella plate body 3-2. When the umbrella frame assembly 3 is in an unfolded state, the upper umbrella plate body 3-1 and the lower umbrella plate body 3-2 are close to each other, and the plug-in part in the upper umbrella plate body 3-1 is plugged into the slot of the lower umbrella plate body 3-2. Each umbrella rib structure 3-3 extends outward and unfolds. When the umbrella frame body is in a folded state, the upper umbrella plate body 3-1 and the lower umbrella plate body 3-2 are away from each other, and the plug-in part in the upper umbrella plate body 3-1 is separated from the slot of the lower umbrella plate body 3-2. Each umbrella rib structure 3-3 is folded inward and folded.

[0044] The rib structure 3-3 includes a long rib and a short rib. The top of the long rib is hinged to the upper umbrella plate body 3-1. The bottom of the short rib is hinged to the lower umbrella plate body 3-2, and the top is hinged to the long rib, thereby forming an umbrella rib structure 3-3 that can be folded, folded or unfolded with the long rib.

[0045] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
