Description

Technical Field

[0001] The invention relates to the field of parasols, in particular to a connecting structure for an oblique rod and an umbrella frame of a parasol hanging umbrella. Background Art

[0002] Parasols are a common sunshade used in recreational areas such as plazas, beaches, and lawns, providing a comfortable, cool space for outdoor activities. Cantilevered parasols (also known as hanging parasols) are popular among consumers due to their upright posts located outside the umbrella. When opened, they offer a high canopy, ample space beneath the umbrella, and excellent sun protection. Currently, hanging parasols typically feature a crank mounted on the upright post, which tightens or loosens the rope to control the opening and closing of the canopy. A diagonal rod is installed between the upright post and the canopy. This rod is connected to the umbrella frame via a connecting structure that rotates when the canopy is folded and remains fixed when the canopy is open to prevent shaking. Currently, this type of connection structure is common and usually includes a fixed connection part for connecting to the diagonal rod and a rotating connection part for connecting to the umbrella frame. The rotating connection part and the fixed connection part are usually eccentrically connected. When this connection structure is fixed, it can only provide strong support in one of the two directions of front and back, while the other direction must rely on the tension of the rope to provide soft support. When a parasol with this connection structure is used outdoors in windy conditions, it will shake greatly. The shaking of the umbrella surface will impact the connection structure, which will cause fatigue of the parts in the connection structure in the long run, easily cause damage to the parts, lead to functional failure, and thus affect the overall service life. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a connecting structure for an oblique rod and an umbrella frame of a sunshade hanging umbrella which has a simple structure, good bearing capacity and stable use.

[0004] The technical solution adopted by the present invention to solve the above technical problems is:

[0005] A connecting structure for an oblique rod and an umbrella stand of a sunshade hanging umbrella, comprising a fixed connecting piece for connecting to the oblique rod of a sunshade hanging umbrella and a rotating connecting piece for connecting to the umbrella stand of the sunshade hanging umbrella, the rotating connecting piece having a first connecting sleeve for mounting the upper end of the umbrella stand, a rotating connecting portion being provided on the first connecting sleeve, the fixed connecting piece having a second connecting sleeve for sleeved on the oblique rod, a rotating connecting seat being provided at the lower portion of the second connecting sleeve, the rotating connecting seat comprising two vertically arranged rotating connecting arms, the two rotating connecting arms being spaced apart and arranged in parallel on the left and right, a rotating connecting cavity being formed between the two rotating connecting arms, the rotating connecting portion having a waist-shaped guide hole passing through on the left and right, the length of the waist-shaped guide hole in the up-down direction being greater than the width of the waist-shaped guide hole in the front-back direction, The cam is connected to the drive means and the drive means is connected to the drive means by which the cam is connected and the drive means are connected, and a plurality of pairs of cams are connected to each other to form a plurality of pairs of cams.

[0006] The opposing inner end surfaces of the two rotating connecting arms are each provided with the locking groove, and the two corresponding side portions of the rotating connecting portion are respectively provided with matching locking protrusions. This achieves a more stable locking position, ensures uniform force on both sides, and gives the entire structure greater rigidity after the locking connection.

[0007] The shaft-type connecting member comprises a pin sleeve bolt and a pin sleeve screw that cooperates with the pin sleeve bolt. The rotating connecting arm is provided with a matching mounting hole. The connecting end of the pin sleeve bolt is inserted through one of the mounting holes, passes through the waist-shaped guide hole, and extends out of the waist-shaped guide hole. The connecting end of the pin sleeve screw is inserted through the other mounting hole and screwed together with the connecting end of the pin sleeve bolt to achieve installation. The shaft-type connecting member has a simple structure, is easy to install, and is low in cost.

[0008] The outer end surface of the rotating connecting arm is removably provided with a protective end cap, and the pin sleeve bolt and the pin sleeve screw are disposed between the two protective end caps. The protective end cap protects the pin sleeve bolt and the pin sleeve screw from the external environment, effectively reducing the probability of rust and corrosion, extending their service life, and making the overall structure more neat and aesthetically pleasing.

[0009] The second connecting sleeve has a positioning opening communicating with the rotating connection cavity. The rotating connection portion is provided with a protrusion provided with a positioning bump that matches the positioning opening. In the locked state, the positioning bump is embedded in the positioning opening, thereby achieving further stable locking and effective strong support.

[0010] The rear protrusion of the positioning protrusion is provided with an abutment boss, the upper end surface of which is located lower than the upper end surface of the positioning protrusion. The second connecting sleeve is provided with an abutment end surface that matches the upper end surface of the abutment boss at a position corresponding to the abutment boss. In the locked state, the upper end surface of the abutment boss abuts the abutment end surface, thereby achieving further stable locking and effective strong support.

[0011] The upper end surface of the abutting boss is a flat end surface, and the abutting end surface is a matching flat end surface, thereby achieving further stable locking and effective strong support.

[0012] The rotating connecting part is provided with a rope threading hole which passes through from top to bottom and is connected with the interior of the first connecting sleeve, so as to realize the threading and installation of the rope and facilitate the connection with the umbrella surface.

[0013] Compared with the existing technology, the advantages of the present invention are: simple structure, the rotational locking between the rotating connection part and the rotating connection seat is achieved through the cooperation of the locking groove and the locking protrusion, the locking is stable, and it is applied to the sunshade hanging umbrella. Even if the rope used to pull the umbrella surface is elastically deformed under the action of wind, it can still have good load-bearing capacity, provide strong and effective support, and achieve a stable connection.
