- The present invention relates to the technical field of umbrellas, in particular to the technical field of sunshade umbrellas, and more particularly to a middle disk of sunshade umbrellas, which is used to connect a short rib with a long rib so that there is an angle between the long rib and the short rib when the umbrella is folded and dead angle is avoided.
- At present, sunshade umbrellas can already be seen everywhere. When an umbrella needs to be unfolded, the shank pulls the umbrella rope or pushes the slider upwards. If there is not a certain angle between the junction of the long rib and the short rib, they will be stuck at the folded status. The long rib and the short rib cannot be unfolded until they are opened to a certain angle. In order to avoid the dead angle of the ribs, its short ribs are connected with long ribs by means of middle disks. However the existing middle disks on the market are mainly connected with long ribs by means of bolts, rivets or blind rivets. The process is increased and the appearance is affected.
- For example, the patent ZL03230857.4 provides a middle disk, in which the middle disk is fixed to a long rib by blind rivets and is fixed to a short rib by means of a tube plug and blind rivets. A stop dog is fixed to the short rib by blind rivets, and the stop dog is disposed at which the middle disk is connected in order to avoid the dead angle of the ribs. Therefore, the structure being complicated, and additionally, there being many blind rivets cause the assembly process to become complicated.
- Therefore, in order to solve the existing aforementioned problems and the defects, a middle disk of sunshade umbrellas of which the structure is concise, the assembly is simple and the appearance is artistic needs to be provided.
- The object of the present invention is to overcome the drawbacks of aforementioned existing technology, and to provide a middle disk of sunshade umbrellas. The middle disk of sunshade umbrellas is ingeniously and uniquely designed, concise in structure, concise in structure, simple to assemble, artistic in appearance and is appropriate to be promoted on a large scale.
- In order to achieve the aforementioned objects, the middle disk of sunshade umbrellas wherein the said middle disk of sunshade umbrellas comprises a first end part and a second end part which are connected with each other. The said first end part is an insertion portion for a short rib and the said insertion portion for a short rib is provided with fixing holes for a short rib. The said second end part has a first clamp arm and a second clamp arm which are disposed opposite to each other. The said first clamp arm has a first boss and the said second clamp arm has a second boss. The said first boss and the said second boss are disposed opposite to each other.
- Preferably, the number of the fixing holes for a short rib is not less than two.
- More preferably, said fixing holes for a short rib are disposed at intervals along the length of the said insertion portion for a short rib.
- Preferably, said first clamp arm and said second clamp arm are both in curved or corner shape.
- Preferably, said middle disk of sunshade umbrellas is composed of a first part and a second part. The said first part comprises a first end and a second end which are connected with each other and the said second end has the said first clamp arm. The said second part comprises a third end and a fourth end which are connected with each other and the said fourth end has the said second clamp arm. The said first end and the said third end contact with each other to form the said insertion portion for a short rib.
- More preferably, said first end has a first groove, and said third end has a second groove. The said first groove and the said second groove are disposed opposite to each other to form the said fixing holes for a short rib.
- More preferably, said first part and said second part are fastened or clamped to each other to achieve the assembly.
- The present invention has the advantage that: the middle disk of the sunshade umbrellas comprises a first end part and a second end part which are connected with each other, and the first end part is an insertion portion fort a short rib; the said insertion portion for a short rib is provided with fixing holes for a short rib; said second end part has a first clamp arm and a second clamp arm which disposed opposite to each other; the said first clamp arm has a first boss and said second clamp arm has a second boss; said first boss and said second boss are disposed opposite to each other, so that the long rib is connected by means of the first boss and the second boss; the insertion portion for a short rib is inserted into the short rib and is fixed by means of blind rivets; it is ingeniously designed, concise in structure, concise in structure, simple to assemble, artistic in appearance, and is appropriate to be promoted on a large scale.

FIG. 1 is an exploded perspective view of one embodiment of the present invention. -
FIG. 2 is the partial perspective assembly view of the embodiment illustrated inFIG. 1 connecting with a short rib and a long rib. -
FIG. 3 is the partial perspective view of the embodiment illustrated inFIG. 1 connecting with a short rib and a long rib. - In order to understand the technical content of the present invention more clearly, the embodiment is exemplified hereinafter to explain in details. It is supposed to be understood that the embodiment is intended to illustrate the present invention and is not intended to limit the present invention.
- Please refer to
FIG. 1 , the middle disk of sunshade umbrellas of the present invention comprises a first end part 1 and asecond end part 2 which are connected with each other. The said first end part 1 is an insertion portion for a short rib and the said insertion portion for a short rib is provided with fixing holes for ashort rib 3. The saidsecond end part 2 has afirst clamp arm 4 and asecond clamp arm 5 which are disposed opposite to each other. The saidfirst clamp arm 4 has afirst boss 41 and the saidsecond clamp arm 5 has asecond boss 51.
