Description

Technical Field

[0001] This utility model belongs to the field of sunshade umbrella technology, and relates to a column top steering component of a banana umbrella. Background Technology

[0002] Sun umbrellas have been widely used as a travel product, and banana umbrellas, as one of these products, are also very popular among users. Banana umbrellas are generally opened and closed by turning a wrench to drive the umbrella ropes set inside the iron pipe, and by tightening and loosening the umbrella ropes.

[0003] Patent application number CN200710051595.3 discloses a banana umbrella for sunshade, which includes a base 13, a support rod 1, a suspension rod 10, and an umbrella canopy bracket 11. The guide joint 4 is horizontally rotatably connected to the top end of the support rod 1. The movable seat 6 is sleeved on the outside of the support rod 1 and is vertically slidably connected and horizontally rotatably connected to the rod body. The rotation axis of the guide joint 4 horizontally rotatably connected to the top end of the support rod 1 and the rotation axis of the movable seat 6 horizontally rotatably connected to the rod body of the support rod 1 are on the same rotation axis. The positioning seat 7 is fixedly connected to the rod body of the support rod 1, and the lower end ring surface of the positioning seat 7 and the upper end ring surface of the movable seat 6 form a corrugated tooth surface connection.

[0004] The hollow joints mentioned above have lower material costs, but they still have some drawbacks: the umbrella body is affected by strong winds, which will put a lot of load on the suspension rod, causing the joint below to be subjected to a lot of downward pressure. Since the joints are mostly restricted by metal pins, the joints will deform relative to the pins. When the deformation is large, it will cause irreversible damage and destroy the structural stability. Summary of the Invention

[0005] This utility model addresses the aforementioned problems in existing technologies by providing a steering component for the top of a banana umbrella. The technical problem this utility model aims to solve is how to balance low material cost and structural stability of the steering component.

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

[0007] A banana umbrella-shaped steering component includes a horizontally arranged cylindrical sliding sleeve and a vertically arranged columnar plug. The lower side of the sliding sleeve has a connecting plate, and the sliding sleeve is hinged to the upper end of the plug through the connecting plate. The lower part of the plug is cylindrical and has a pin hole that radially penetrates the plug. The plug is characterized in that a vertically arranged reinforcing rib plate is provided between the inner walls of the lower part of the plug and is arranged to intersect the axis of the pin hole. The lower edge of the reinforcing rib plate is slightly higher than the position of the pin hole.

[0008] The plug is used to connect to the top of the banana umbrella's support post. A sliding sleeve allows a curved tube used to suspend the umbrella body to pass through, and its movement relative to the plug adapts to the sliding motion of the curved tube relative to the sliding sleeve. A connecting plate on the lower side of the sliding sleeve ensures the strength of the hinged joint. A radially penetrating pin hole is provided at the bottom of the plug for a pin to pass through, ensuring a fixed connection between the plug and the support post. Vertical reinforcing ribs are installed between the inner walls of the lower part of the plug, with the ribs intersecting the axis of the pin hole, and the lower edge of the reinforcing ribs slightly higher than the pin hole. This design strengthens the support of the plug. When subjected to a large downward load from the sliding sleeve, the inner wall of the pin hole deforms due to contact with the pin shaft. The lower edge of the reinforcing rib can then begin to contact the surface of the pin shaft and support it on the pin shaft to prevent the entire plug from continuing to move downward. This avoids excessive deformation of the inner wall of the pin hole, which could cause irreversible damage. At the same time, the rib occupies less material, which can still ensure the low material cost of the hollow plug. Furthermore, the reinforcing rib is not easily obstructed during the pin shaft insertion and installation, ensuring smooth installation. This approach balances the low material cost and structural stability of the steering component.

[0009] In the aforementioned banana umbrella-shaped steering component at the top of the column, the reinforcing rib has an X-shaped cross-section. This design helps to give the reinforcing rib a higher overall structural strength, ensuring a stable limiting and supporting effect when its lower edge contacts the pin.

[0010] In the aforementioned banana umbrella-shaped column-top steering component, the outer periphery of the plug has several vertically arranged and circumferentially spaced protrusions. This helps to reduce the contact area between the outer periphery of the plug and the inner wall of the column during insertion, thereby reducing insertion resistance and facilitating smooth assembly.

[0011] In the aforementioned banana umbrella-shaped steering component at the top of the pin hole, both ends of the pin hole are located on the convex ridge. The convex ridge has a larger radial dimension, which helps to slightly increase the support length of the inner wall of the pin hole, improve the load-bearing capacity of the inner wall of the pin hole, and reduce the probability of deformation damage.

[0012] In the aforementioned banana umbrella-shaped column-top steering component, the upper part of the plug has a circumferentially arranged annular shoulder. This allows for restraint and support by the shoulder abutting against the upper edge of the column after the plug is inserted. It also ensures that the height of the pin hole matches the height of the through hole at the upper end of the column through which the pin passes, facilitating assembly.

[0013] In the aforementioned banana umbrella column-top steering component, the plug is an injection-molded part, and a gap is left between the upper end of the protruding ridge and the shoulder. This helps to avoid the formation of flash at the joint between the protruding ridge and the shoulder, which would affect the proper engagement of the shoulder and the column, thus ensuring ease of assembly.

[0014] Compared with the prior art, the advantages of this utility model are as follows:

[0015] The steering component at the top of this banana umbrella is reinforced with a rib plate. When the plug is subjected to a large load, the lower edge of the rib plate can start to form contact support with the pin surface, thereby avoiding excessive deformation of the inner wall of the pin hole and causing irreversible damage. This design balances the low material cost and structural stability of the steering component. Attached Figure Description

The sliding sleeve 1 is hinged to the upper end of the plug 2 through the connecting plate 11. The lower part of the plug 2 has a pin hole 21 that radially penetrates the plug 2. The plug 2 is used to be inserted into the top of the banana umbrella column. The sliding sleeve 1 allows a curved tube for suspending the umbrella body to pass through, and can be adapted to the sliding action of the curved tube relative to the sliding sleeve 1 by swinging relative to the plug 2. The outer periphery of the plug 2 has several vertically arranged and circumferentially spaced protrusions 23, and both ends of the pin hole 21 are located on the protrusions 23.

[0023] like Figure 2 As shown, the lower part of the plug 2 is cylindrical, and there is a vertically arranged reinforcing rib 22 between the inner walls of the lower part of the plug 2, which is arranged to intersect the axis of the pin hole 21. The cross-section of the reinforcing rib 22 is X-shaped.

[0024] like Figure 3 As shown, the upper part of the plug 2 has a shoulder 24 arranged in a ring around the circumference, and there is a gap between the upper end of the protrusion 23 and the shoulder 24.

[0025] like Figure 4As shown, the lower edge of the reinforcing rib 22 is slightly higher than the pin hole 21.
