Technical Field
[0001] The utility model relates to the technical field of umbrellas, in particular to an assembly structure of a middle rod and an umbrella head of an umbrella. Background Art
[0002] An umbrella is a tool that can provide a cool environment or shelter from rain, snow, sunlight, etc. China is the first country in the world to invent the umbrella, and the umbrella is an important creation of the Chinese working people.
[0003] The umbrella head is generally made of plastic or wood with a relatively light specific gravity. In addition to reducing material costs, this can also make the umbrella lightweight to reduce the burden on the user when holding it. The middle rod used to support the ribs and the umbrella cloth is made of metal with a certain strength to avoid bending during use. In addition, in order to avoid loosening and separation during use, the middle rod and the umbrella head are fixed together by a fixing means, such as adhesive bonding or screws or threads.
[0004] When using adhesive bonding, the center rod and the umbrella head need to be pressed tightly to allow the glue to dry. Although the fixing method of screws and bolts can achieve faster fixation between the two than the adhesive fixing method, it is necessary to continuously turn the screws or the center rod when fixing the center rod and the umbrella head so that the threads of the screws or the center rod can be fixed to the umbrella head. This fixing method takes a long time to assemble the center rod and the umbrella head in batch assembly, and the center rod and the umbrella head cannot be quickly connected and fixed, thereby failing to increase the assembly speed of the center rod and the umbrella head. Utility Model Content

A corner block, a moving groove opened on the umbrella head and connected with the mounting groove and located on the outside of each of the regular triangular blocks, used for allowing the regular triangular block to move away from the end of the connecting column when the connecting column drives the inverted triangular block to descend and squeeze the regular triangular block, a linkage mechanism provided between the regular triangular block and the umbrella head, used for allowing the regular triangular block to move away from the end of the connecting column in the moving groove when the inverted triangular block squeezes the regular triangular block, and driving the regular triangular block to move toward the end of the connecting column in the moving groove when the connecting column descends to a predetermined position in the mounting groove so that the regular triangular block and the inverted triangular block are engaged, and a guiding mechanism provided between the connecting column and the umbrella head, used for guiding the connecting column when the connecting column descends in the mounting groove to prevent the connecting column from rotating.
[0007] A further improvement is that the linkage mechanism includes a compression spring arranged between the regular triangular block and the umbrella head and located in the moving groove, and is used for contracting when the inverted triangular block squeezes the regular triangular block so that the regular triangular block moves away from the end of the connecting column in the moving groove, and when the connecting column descends to a predetermined position in the installation groove, the regular triangular block is driven to move closer to the end of the connecting column in the moving groove so that the regular triangular block and the inverted triangular block are engaged with each other; a side slot provided on the side end surface of the umbrella head and close to the end of the moving groove; a limiting slot provided on the umbrella head and connected with the side slot and the moving groove; a sliding rod slidably arranged on the umbrella head and located in the limiting slot, one end of which is connected to the regular triangular block and the other end of which is located in the side slot; a limiting block provided at the other end of the sliding rod; a releasing member provided on the limiting block and located in the side slot, and is used for driving the limiting block to drive the sliding rod to pull the regular triangular block in the moving groove away from the end of the connecting column; and the compression spring is sleeved on the outer side of the sliding rod.
[0008] A further improvement is that the release member includes a release plate arranged on the limit block and located in the side groove, which is used to drive the limit block to drive the sliding rod to pull the equilateral triangle block in the moving groove away from the connecting column end when driven by external force, and a rotating rod with one end arranged on the release plate and the other end rotatably arranged on the limit block, which is used to allow the release plate to rotate after the release plate drives the sliding rod to pull the equilateral triangle block in the moving groove away from the connecting column end so that the release plate is engaged with the umbrella head, and the length of the release plate is greater than the width of the side groove.
[0009] A further improvement is that the guide mechanism includes a longitudinal guide groove opened on the umbrella head and connected to the installation groove, and a longitudinal guide block arranged on the side end surface of the connecting column for slidingly cooperating with the longitudinal guide groove when the connecting column descends in the installation groove.
[0010] After adopting the above technical scheme, the beneficial effects of the utility model are as follows: when it is necessary to assemble between the centering rod and the umbrella head, the connecting post is aligned with the installation slot of the umbrella head, and the center rod is driven to drive the connecting post to descend in the installation slot. When the connecting post descends in the installation slot, the connecting post is guided by the guide mechanism to prevent the connecting post from rotating. When the connecting post descends, the inverted triangle block is driven to descend and squeeze the regular triangle block, so that the regular triangle block moves away from the end of the connecting post in the moving slot. As the center rod is held and drives the connecting post to be pressed down toward the end of the umbrella head, the connecting post is driven to descend to a predetermined position. At this time, the linkage mechanism drives the regular triangle block to approach the end of the connecting post in the moving slot, so that the regular triangle block and the inverted triangle block are engaged to limit the rising of the connecting post in the installation slot, thereby assembling and fixing the center rod to the umbrella head. This fixing method takes a shorter time to assemble the centering rod and the umbrella head in batch assembly, and the center rod and the umbrella head can be quickly connected and fixed, thereby improving the assembly speed of the centering rod and the umbrella head.
