The present disclosure relates to the field of sunshade umbrellas, and in particular, to a cantilever umbrella.
The cantilever umbrella is the most multifunctional one among outdoor sunshade umbrellas, which is a creative shading manner. It can offer a spacious under-canopy area for freely arranging outdoor furniture. A canopy can be freely rotated to block sunlight. Compared with another umbrella, the cantilever umbrella provides a better shading effect and is more convenient to operate. The cantilever umbrella is operated via a handle to rotate, ascend and descend, thereby being labor-saving and convenient. However, for some cantilever umbrellas, an elongated curved pole is adopted as a cantilever arm pole, and consequently, costs are increased as a large transportation case is required to package components of the cantilever umbrella. Some cantilever umbrellas feature a fixed-angle canopy that cannot be adjusted after being opened, and therefore, an angle of the canopy cannot be adjusted according to an actual condition.
To overcome the disadvantages in the conventional technology, the present disclosure provides a cantilever umbrella that has effects of saving transportation costs and conveniently adjusting an angle of a canopy.

The first cantilever armand the second cantilever armare connected stably through the first screws. The first screwsare screwed out to facilitate dismounting of the first cantilever armand the second cantilever arm. After the first cantilever armand the second cantilever armare dismounted, a size of a transportation case can be reduced when the cantilever umbrella is packaged for transportation, and therefore, transportation costs are reduced. When the first cantilever armand the second cantilever armslide in the locking blockand the locking sliding sleeve, an angle of the canopyis adjusted with sliding of the first cantilever armand the second cantilever arm. In this way, the angle of the canopyis conveniently adjusted by sliding the first cantilever armand the second cantilever armin the locking blockand the locking sliding sleeve.
Two first pulleysare disposed in the locking block. A second pulleyis disposed in the locking sliding sleeve. A rolling ballis disposed in each of the first pulleyand the second pulley.

With the adoption of the technical solution, the first cantilever armand the second cantilever armseparately pass through the first pulleyand the second pulleyand are in contact with the rolling balls, to facilitate sliding of the first cantilever armand the second cantilever armin the locking blockand the locking sliding sleeve. The knobis rotated to drive the second screwto rotate, to fasten the first cantilever armand the second cantilever armby the locating blockthrough the second screw.
A connectoris disposed on the second cantilever arm. A protruding portionis disposed in the first cantilever arm. The connectorfits the protruding portion. The connectoris connected to the protruding portionthrough eight first screws. A capis disposed outside the first screw.
With the adoption of the technical solution, after the connectorfits the protruding portion, the connectorstably fits the protruding portionthrough the first screw. The first screwis protected by the cap.
A fastening memberis fixedly disposed beneath the hanging member. A connecting rodis fixedly disposed below the fastening member. A fitting memberis disposed on the connecting rod. Eight first umbrella ribsare disposed on the fastening member. Eight second umbrella ribsare disposed on the fitting member. The first umbrella ribsand the second umbrella ribsare connected to each other through eight rotating members.
The opening-closing structural component of the canopyincludes a handle housing, a left pressure cover, a right pressure cover, a rope winding wheel, a hand crank, a torsion spring, a rope, and a crankshaft handle. The ropeis located in the fitting member, the connecting rod, the fastening member, the hanging member, the first cantilever arm, and the second cantilever arm. One end of the ropeis fixedly connected to the fitting member. The other end of the ropeis fixedly connected to the rope winding wheel. Each of the left pressure coverand the right pressure coveris connected to the handle housingthrough a third screw. A lugis disposed on the fitting member. The lugfits an end of the connecting rod.
With the adoption of the technical solution, a roller on the rope winding wheelis internally in contact with the handle housing. The torsion springis fixedly connected to one end of the rope winding wheel, and the torsion springand the one end of the rope winding wheelare disposed in the left pressure cover. Two ends of the torsion springare separately in contact with the left pressure cover. The roller on the rope winding wheeland the two ends of the torsion springare separately in contact with the left pressure cover, to increase a friction force when the rope winding wheelis rotated in the handle housing, thereby preventing the rope winding wheelfrom rotating in the handle housingwhen the canopyis opened. An end of the crankshaft handlefits the hand crank, and the rope winding wheeland the hand crankare integrally formed, to drive the rope winding wheelto rotate through the crankshaft handle. The rope winding wheelis rotated to retract and extend the rope. When the reaction and extension ropeis extended, the lugis separated from the connecting rodto retract the canopy. When the ropeis tightened, the lugfits an end of the connecting rodto open the canopy. The left pressure coverand the right pressure coverare stably disposed on the handle housingthrough the third screw.
A supporting frameis disposed in the base. The supporting frameis fixedly connected to the baseand a discseparately. A bearingis disposed on the disc. A gearis disposed above the bearing. The gearis fixedly connected to a rotating portion. An inserting rodis disposed on the rotating portion. The inserting rodis connected to the upright polethrough inserting. A limiting plateis disposed on the base. The inserting rodpenetrates through the limiting plate.
A clamping component is disposed on a side of the disc. The clamping component includes an edge block, an upper block, and a foot pedal. A clamping portionis disposed on the upper block.

After the inserting rodon the rotating portionis connected to the upright polethrough inserting, the upright poleis disposed stably. When the inserting rodand the upright poleneed to be rotated, the foot pedalis stepped down to separate the clamping portionfrom the teeth, thereby driving the canopyto rotate by rotating the upright pole. After rotation to a required angle, the foot pedalis released to dispose the clamping portionamong the teeth, thereby completing rotation. When the foot pedalis not stepped on, the foot pedalmakes the clamping portionbeing always disposed among the teeth of the gearthrough the spring. The springis located on an outer side of the cross rod, one end of the springis in contact with and connected to the upper block, and the other end of the springis in contact with and connected to the edge block.
In conclusion, the present disclosure has the following beneficial effects: The connectoron the first cantilever armis connected to the protruding portionon the second cantilever armthrough the second screw, thereby facilitating dismounting of the first cantilever armand the second cantilever arm. After the first cantilever armand the second cantilever armare dismounted, a size of a transportation case can be reduced when the cantilever umbrella is packaged for transportation, and therefore, costs are reduced. When the first cantilever armand the second cantilever armslide in the locking blockand the locking sliding sleeve, an angle of the canopyis adjusted with sliding of the first cantilever armand the second cantilever arm. In this way, the angle of the canopyis conveniently adjusted by sliding the first cantilever armand the second cantilever armin the locking blockand the locking sliding sleeve.
