Description

Technical Field

[0001] The utility model belongs to the technical field of Roman umbrellas and relates to an umbrella stand of a Roman umbrella. Background Art

[0002] Roman umbrellas are usually used in outdoor activities or placed outside stores to provide shade and shelter from the sun and rain. In windy weather, the umbrella surface of the Roman umbrella will be subject to greater wind force, so the umbrella frame needs to have higher wind resistance. The existing Roman umbrella structure with multiple pull rods improves the stability and windproof effect of the umbrella frame by setting multiple pull rods.

[0003] Existing patents such as the Chinese patent application [Authorization Announcement No.: CN220369608U] disclose a multi-pull rod assembly structure for a sunshade hanging umbrella, including a column, an oblique rod and at least two pull rods, one end of each pull rod is connected to the top of the column, one end of the oblique rod is connected to the column, and the other end of each pull rod is connected to the oblique rod. This multi-pull rod assembly structure includes a column transition sleeve mounted on the top of the column and an oblique rod transition sleeve mounted on the oblique rod. The column transition sleeve has a top plate and side plates connected to both sides of the top plate and vertically downward. All pull rods are arranged in sequence on the sides of the side plates and are connected by connecting pieces. The oblique rod transition sleeve has two vertically arranged connecting plates. All pull rods are arranged in sequence on the sides of the connecting plates and are connected by connecting pieces.

[0004] The above structure is achieved by connecting the top ends of multiple pull rods to the side panels of the column transition sleeves through the column transition sleeves installed on the top ends of the columns, thereby realizing the connection between the pull rods and the column transition sleeves. However, when encountering strong winds, since the columns and the pull rods are only connected by the column transition sleeves and screws, when the wind is strong, the column transition sleeves and the columns will shake, resulting in low wind resistance of the Roman umbrella. Utility Model Content

[0005] The purpose of the utility model is to solve the above problems in the existing technology and to propose an umbrella stand for a Roman umbrella. The technical problem to be solved by the utility model is: how to solve the problem of poor windproof performance of the existing Roman umbrella.

[0006] The purpose of this utility model can be achieved through the following technical solutions:

[0007] A Roman umbrella stand includes a fixed rod, an oblique rod and at least two pull rods, the lower ends of the pull rods are hinged to the middle of the oblique rod, and the umbrella stand is characterized in that the umbrella stand also includes a clamping seat with a U-shaped cross section formed by extending to the same side into two side wings on the basis of a tubular component, the upper end of the pull rod is hinged to the clamping seat, and the fixed rod is clamped between the two side wings of the clamping seat and abuts against the inner side of the clamping seat, and is fixedly connected to the clamping seat by a fastener.

[0008] The clamping seat is a clamping seat with a U-shaped cross section formed by extending to the same side into two side wings. The upper end of the pull rod is hinged on the clamping seat. Since the cross section of the clamping seat is U-shaped, an opening is formed at its outer end. The fixing rod is clamped between the two side wings of the clamping seat from the opening, and fits and abuts against the inner side of the clamping seat and is fixed to the clamping seat through fasteners. The connection between the fixing rod and the clamping seat is that the fixing rod is first inserted into the clamping seat and fits and abuts against the inner side of the clamping seat to achieve the positioning of the fixing rod. After positioning, it is fixed by fasteners. The positioning through the semi-enclosed structure improves the connection between the clamping seat and the fixing rod. The stability of the clamping seat is improved, and since the pull rod and the clamping seat are hinged, the pull rod is connected to other positions on the clamping seat, and the fixed rod and the clamping seat are connected at the side wings. In the structure of the entire clamping seat, the strength of the side wings is the lowest. By partially embedding the fixing rod, the open end of the clamping seat is tightened by the fixing rod, which improves the structural strength of the side wings after connection. After the clamping seat is connected to the fixing rod, the strength of the clamping seat is higher. In windy weather, the stability of the connection between the pull rod and the fixing rod is improved by installing and fixing at multiple points and setting a high-strength clamping seat.

[0009] The above-mentioned fixing rod can be a column independently set on the ground base, or a profile fixed on the wall, so that the umbrella stand can be used independently or as a wall-mounted Roman umbrella, thereby improving the practicality of the Roman umbrella.

[0010] In the above-mentioned umbrella stand of the Roman umbrella, the inner side of the clamping seat has a protruding flat abutting surface, and the fixing rod has a flat supporting portion, and the abutting surface fits and abuts against the supporting portion.

[0011] The abutment surface is convex, so that the inner end of the clip seat is a protruding abutment surface, which increases the structural strength of the clip seat at the abutment surface and improves the stability of the clip seat and the fixing rod. The abutment surface is flat and the support part is also flat. When they abut against each other, the fitting area is larger, thereby improving the stability of the installation connection.

[0012] In the above-mentioned umbrella stand of the Roman umbrella, the inner side of the clamping seat has an arc-shaped limiting surface located on both sides of the abutting surface, and the two sides of the supporting part have limiting parts arranged along the vertical interval, and the outer side walls of the limiting parts are in contact with the limiting surface.

[0013] By making the limiting surface fit against the limiting portion and the arc surface design, the area of ​​the fitting and abutting between the clamping seat and the fixing rod is increased, so that the positioning of the fixing rod is more stable.

[0014] In the above-mentioned umbrella stand of the Roman umbrella, the outer ends of the two limiting parts are arranged close to each other.

[0015] The two limiting parts form a shape similar to an arch bridge, which has the effect of enhancing wind resistance. It is less likely to deform than a straight board, and improves the stability of the limiting part and the abutting surface.

[0016] In the above-mentioned umbrella stand of the Roman umbrella, the closed end of the snap-fit ​​seat is a hollow tubular mounting portion, and the mounting portion has a plurality of plate-shaped reinforcing walls arranged parallel to each other. The upper end of the pull rod is hinged on the mounting portion, and the reinforcing walls are all arranged parallel to the pull rod.

[0017] By providing a hollow tubular mounting portion with multiple reinforcing walls inside the mounting portion, the structural strength of the mounting portion is improved while achieving a lightweight design, and the stability of the pull rod hinge is improved. In addition, by setting it in parallel, the structural strength of the mounting portion along the front and rear directions is increased. When encountering strong winds, the pull rod is likely to swing back and forth along the mounting portion. Therefore, by increasing the structural strength of the coupling in this direction, the stability of the connection between the mounting portion and the pull rod is improved, thereby improving the windproof effect of the umbrella stand.

[0018] In the above-mentioned umbrella stand of the Roman umbrella, needle bearings are provided between the pull rod and the mounting portion.

[0019] Through the setting of the needle bearing, although the surface contact is changed into multiple line contacts, when the wind is strong, the pull rod is easily affected by the wind and deflected in the front and back directions, and the needle rollers on the needle bearing can swing in the front and back directions, thereby buffering the deflection of the pull rod, so that the connection between the pull rod and the mounting part always maintains a stable connection, and the pull rod will not squeeze the mounting part after deflection, thereby ensuring the stability of the connection between the pull rod and the mounting part, and also ensuring the stability of the pull rod swinging during the umbrella folding and opening process.

[0020] In the above-mentioned umbrella stand of the Roman umbrella, a connecting sleeve is clamped in the middle of the diagonal rod, and two pull rods are provided. The two pull rods are respectively located on both sides of the connecting sleeve and are hinged to the diagonal rod through fasteners. Countersunk holes are provided on both side walls of the connecting sleeve, and needle bearings and support gaskets located on both sides of the needle bearings are provided in the countersunk holes, and one of the support gaskets is in contact with the side wall of the corresponding pull rod.

[0021] A connecting sleeve is clamped on the diagonal rod, and two pull rods are respectively located on both sides of the connecting sleeve. The pull rod and the diagonal rod are hinged by fasteners, and countersunk holes are opened on the two side walls of the connecting sleeve. The supporting gasket makes the contact between the connecting sleeve and the pull rod surface contact. Then, through the cooperation of the two surface contacts, the connection limit of the two ends of the pull rod is realized, and the smooth swing of the diagonal rod is ensured, thereby achieving the purpose of improving the windproof performance.

[0022] In the above-mentioned umbrella stand of the Roman umbrella, the connecting sleeve is U-shaped and is clamped upwardly at the middle portion of the oblique rod.

[0023] The shape of the connecting sleeve allows it to wrap around the lower side of the diagonal rod during connection, and the pull rod always has the pulling force to pull the diagonal rod upward, thereby improving the stability of the connection between the diagonal rod and the pull rod.

[0024] In the above-mentioned umbrella stand of the Roman umbrella, an armrest shell is slidably connected to the fixed rod, and the lower end of the oblique rod is hinged to the armrest shell by a hinge bolt and a nut. Mounting countersunk holes are opened on the side walls on both sides of the armrest shell, and needle bearings and support washers on both sides of the needle bearings are provided in the mounting countersunk holes. The hinge bolts and nuts press the corresponding needle bearings and support washers into the mounting countersunk holes.

[0025] A mounting countersunk hole is opened on the armrest shell. By arranging a needle bearing and a support gasket in the mounting countersunk hole, the diagonal rod can be stably connected to the fixed rod through the armrest shell. The contact area is increased by the support gasket, so that there is also surface contact between the diagonal rod and the armrest shell, which increases the stability of the connection and improves the wind resistance.

[0026] In the above-mentioned umbrella stand of the Roman umbrella, the above-mentioned umbrella stands are provided on both the left and right sides of the fixing rod.

[0027] In different usage environments, the left and right sides of the fixed rod can be connected with the clamping seats to achieve the connection of the left and right sides of the fixed rod with the umbrella stand, thereby increasing the use area of ​​the Roman umbrella and improving the practical performance of the Roman umbrella.

[0028] Compared with the existing technology, the umbrella stand of this Roman umbrella has the following advantages: since the pull rod and the clamping seat are hinged, the pull rod is connected to other positions on the clamping seat, and the fixed rod and the clamping seat are connected at the side wings. In the structure of the entire clamping seat, the strength of the side wings is the lowest. By partially embedding the fixing rod, the open end of the clamping seat is tightened by the fixing rod, which improves the structural strength of the side wings after connection. After the clamping seat is connected to the fixing rod, the strength of the clamping seat is higher. In windy weather, the stability of the connection between the pull rod and the fixing rod is improved through multiple points of installation and fixation, as well as the setting of a high-strength clamping seat.
