Description

Automatic opening and closing structure of folding umbrella

Technical field:

The utility model relates to the technical field of umbrellas, in particular to an automatic opening and closing structure of a folding umbrella.

Background technique:

At present, the automatic umbrellas that appear on the market are only supported by a spring when they are opened. Regardless of whether the spring is set outside the umbrella rod or in the umbrella rod, the supporting force is slightly insufficient, so that the lower nest body cannot be opened in place or the umbrella can not be fully opened. After opening, its umbrella surface is easily affected by the wind, hindering the shielding effect. In addition, due to the lack of support of the spring for the folding automatic umbrella, the rod in the umbrella can only be made into 2 to 3 sections to cooperate with expansion and contraction, and the umbrella surface must have a suitable shielding surface after it is opened, so the length of the rod in each section of the umbrella There must be a certain length, so that the length of the umbrella is too long after it is folded, making it inconvenient to carry. Recently, in order to solve the defect that the lower nest body is not in place due to insufficient spring support, people have a pulley and a pulley structure in the umbrella rod, and one end of the pull rope is connected to the fixed seat at the lower end of the umbrella rod. , and the other end is connected to the lower nest body after bypassing the pulley, causing the user to stretch the lower nest body upwards while opening the umbrella, so that the lower nest body reaches the position. Although this structure reaches the umbrella It is fully opened, but the size of the umbrella is still too large to be portable, and the umbrella does not have the function of automatically retracting the umbrella.

Invention content:

The purpose of the utility model is to provide an automatic opening and closing structure of a folding umbrella that shortens the length of the umbrella when it is folded, is more convenient to carry, not only enhances the opening force of the umbrella, but also automatically closes the umbrella.

The utility model is realized through the following technical scheme: the folding umbrella automatic opening and closing structure includes an umbrella handle, an umbrella middle rod, a lower nest body, an upper nest body, umbrella ribs, pull ropes and pulleys, and the umbrella ribs are foldable. One end of the main bone is pivotally connected to the upper nest, the other end is pivotally connected to the middle of the inner ramus, one end of the inner ramus is pivotally connected to the lower nest, the other end is pivotally connected to the middle main bone, and the inner ramus is connected to the middle main bone There is a small spring connection between them, the central hole of the small spring runs through a connecting bone, the lower nest body slides outside the umbrella rod, the upper nest body is fixedly connected to one end of the umbrella rod, and the other end of the umbrella rod is fixedly connected to the umbrella handle Above, the rod in the umbrella includes multiple sections of tubes, each of which is nested and connected to each other. There is a spring in the center hole of the rod in the umbrella. The flange end of the hollow rod is provided with a pulley, and the flange end is embedded in the corresponding groove of the upper nest body and is fixedly connected with the upper nest body. The other end of the spring is supported on a buckle seat, and the buckle seat is placed in the umbrella. The center hole of the lower end of the rod is fixedly connected with the umbrella handle. The buckle seat is hollow and the middle part is provided with a horizontal through groove. The hook is in the shape of a bullet, and there is an annular boss under it, and the opposite side of the hook is supported by a shrapnel. The shrapnel is "V" shaped, and its two ends are embedded in the buckle seat and the The middle part of the shrapnel protrudes into the transverse channel of the buckle seat and is supported on one side of the hook. The other end of the drawstring extends upwards and passes through the hollow rod along the inner hole of the umbrella rod. Go out, go around the pulley in the flange end of the hollow rod, the pulley on the lower nest body and the pulley on the upper nest body and then fixedly connect to the lower nest body. After the lower end of the lower nest body is embedded in the groove of the umbrella handle, the upper nest body The button hole is connected with the hook on the button. The end of the lower nest body embedded in the umbrella handle is provided with a guide block. The guide block cooperates with the guide groove on the umbrella handle. The button hole of the lower nest body is located on the opposite side of the guide block. , the button is movably connected with the umbrella handle, a limit pin is set in the corresponding hole on the umbrella handle, one end of which is pressed against the button, there is a contact arm on the opposite side of the button and the button is hinged with the button, and the contact arm is supported by a torsion spring One end of the contact arm protrudes into the transverse channel of the buckle seat after the lower nest body exits the groove of the umbrella handle, and contacts the hook connected to the end of the pull cord. The lower end of the umbrella handle is provided with a bottom cover, and the center of the bottom cover is provided with a boss , the boss is provided with a groove corresponding to the shape and size of the lower end of the umbrella rod, the lower end of the umbrella rod is embedded in the groove of the bottom cover, and a pin is sequentially connected to the umbrella handle, the bottom cover, the umbrella rod and the umbrella rod The buckle seat, and extended to the other side of the umbrella handle.

After adopting such a structure, the structure of the pulley and the pull rope on the umbrella not only enables the lower nest body to rise to the right position, but also allows the umbrella surface of the umbrella to be fully opened, increasing the supporting force when the umbrella is opened, and can effectively reduce the stick in the umbrella The length of each segment of the tube body on the upper part greatly reduces the volume of the umbrella when it is closed, and it is more convenient to carry.
