Description

  The present invention is in the technical field of umbrellas, and in particular relates to high strength umbrellas.

  Umbrellas are a sunshade or rain protection tool and play an important role in daily life, but in the case of conventional umbrellas, there is a universal problem. That is, when the umbrella is used for a while, the parent bone is slightly deformed, and when closing the umbrella, the parent bone is slightly bent due to the memory fatigue degree of the parent bone, and when continuing as it is, the parent bone is deformed severely and the umbrella life In addition, the "bulge" forms at the central position of the umbrella and affects the beauty of the umbrella as a whole. At present, there are many irregular shapes in the parent bone, and the connection between the parent bone, the joint and the dowel needs to be adjusted carefully, and the connection work between the parent bone, the joint and the dowel is very troublesome. Therefore, there is a need to improve this.

  The object of the present invention is to provide a high strength umbrella against the deficiencies of the existing technologies mentioned above.

  The present invention includes a middle rod body, a plurality of frames provided to surround the umbrella cloth and the middle rod body, the frame includes a rib and a base bone connected to each other, and the umbrella cloth is the middle rod body. A high strength umbrella is provided, which is connected to a parent bone, the parent bone is an equilateral triangular prism, the parent bone is provided on the inner rod body, and one side of the parent bone is in contact with the umbrella cloth.

  The three sides of the parent bone are arc-shaped sides.

  An anti-shock rubber sleeve is fitted to the proximal bone to accommodate the movement of the opening of the receiving bone.

  The parent bone is made of FRP.

  When the above-mentioned structure is adopted, the present invention has the following advantages over the existing technology.

  1. The parent bone adopts a regular triangular prism type, and the symmetry makes injection molding connection between the parent bone, the joint and the dowel very convenient.

  2. The equilateral triangular prism base bone has high bending strength and good stability.

  3. The prominence is provided in accordance with the inner rod body, and the contact area between the prominance and the umbrella cloth is increased by bringing the one side of the prominance into contact with the umbrella cloth, and the prominence is It becomes difficult to slip.

It is a block diagram of the high intensity | strength umbrella of embodiment of this invention. It is a cross-sectional view of the parent bone of the high strength umbrella similarly.

  Only the preferred embodiments of the present invention are described below, and the present invention is not limited to the embodiments. The invention will now be described in more detail with reference to the drawings and examples.

  The high strength umbrella of the embodiment of the present invention is as shown in FIG. 1 and FIG. The high strength umbrella includes a middle rod body 1, a plurality of groups of frames 2 provided so as to surround the umbrella cloth and the middle rod body 1. The middle rod body 1 includes an upper wheel 4, a lower wheel 5 and a handle 6 provided to the middle rod 3 and the middle rod 3. The frame 2 comprises a rib 8 and a rib 9 connected to one another through a dowel 7. The abutment 8 is connected to the runner 5 through a joint. The parent bone 9 is connected to the upper wheel 4 through the connection portion 10 in the parent bone 9, in which the dowel 7 and the connection portion 10 are connected to the parent bone 9, and the umbrella cloth is connected to the center rod body 1 and the parent bone 9 ing.

  As shown in FIG. 2, the main bone 9 is an equilateral triangular prism, and the main bone 9 is provided in accordance with the middle rod main body 1, and one side of the main bone 9 is in contact with the umbrella cloth. Three sides of the parent bone 9 are arc-shaped sides. The main bone 9 adopts an equilateral triangular prism type, and the symmetry of the shape makes the injection molding connection between the main bone 9, the connection portion 10 and the dowel 7 very convenient. The three sides of the parent bone 9 are arc-shaped sides, which make it difficult to wear the umbrella cloth.

  On the proximal bone 9 is fitted an anti-shock rubber sleeve 11 for accommodating the movement of the sharp opening of the bone support 8, in which the sharp opening is the joint in the bone receiving bone 8, shock protection The rubber sleeve 11 can avoid that the joint wears the proximal bone 9.

  The main bone 9 is made of FRP, which is a fiber reinforced plastic. The tensile strength of FRP is high, almost no plastic deformation occurs, and the stress and strain during tension rise with linear elasticity until brittle fracture. FRP has a long service life due to its high resistance to corrosion and fatigue. Since FRP has high specific strength and is so-called light weight and high strength, adopting FRP material reduces the weight of the structure and simplifies the construction, and its weight is usually 20% of that of steel. Therefore, the FRP base 9 has the advantages of high strength, resistance to deformation, long service life, and light weight.
