Description

Technical Field

[0001] The invention relates to the technical field of umbrella ribs, and in particular to a reinforced umbrella rib structure. Background Art

[0002] An umbrella is a tool that provides shade or shelters from rain and snow. The materials used to make an umbrella usually include stretchable cloth, and other materials that can be used as a frame and winding wire. It is held up by hand when used. The main purpose of the umbrella when it was first invented was to be used as a rain gear to keep out the rain on rainy days, but now it is also often used to block the sun. Umbrellas are a common tool for people to shelter from the rain. Their main structure is composed of an umbrella cover and ribs, and the ribs mainly play a supporting role.

[0003] The existing umbrella ribs do not have a reinforced structure. When encountering strong winds, heavy rain and heavy snow, the umbrella ribs will break due to the weight, and the umbrella ribs are easy to bend upwards, causing the umbrella ribs to flip over, which can easily cause the umbrella ribs to deform, bend and be damaged. Summary of the invention

[0004] In view of the deficiencies of the prior art, the present invention provides a reinforced umbrella rib structure, which solves the problem of umbrella rib breakage and umbrella rib deformation and bending leading to damage.

[0005] To achieve the above object, the present invention is implemented through the following technical solutions: a reinforced umbrella rib structure, including a main pole, a reinforcement piece is fixedly connected to the top of the main pole, a first connection piece is fixedly connected to the central position of the reinforcement piece, the main ribs are rotatably connected to the outer side of the first connection piece, a sliding sleeve is slidably connected to the surface of the main pole, a second connection piece is fixedly connected to the outer wall of the sliding sleeve, a second connection piece is rotatably connected to the outer side of the second connection piece, a secondary rib is fixedly connected to the surface of four second connection pieces, a fixing plate is fixedly connected to the top of the left and right sides of the outer wall of the secondary rib, and a third connection piece is fixedly connected to the opposite side of two adjacent fixing plates, a first reinforcement rib and a second reinforcement rib are arranged on the inner wall of the secondary rib, a second reinforcement piece is fixedly connected to the inner wall of the main rib, the first reinforcement piece is fixedly connected to the inner side of the second reinforcement piece, and a connecting strip is arranged between the first reinforcement piece and the second reinforcement piece.

[0006] In some embodiments, the third connecting column is fixedly connected to the main rib, and rotation holes are provided on both left and right sides of the outer wall of the auxiliary rib.

[0007] In some embodiments, a fourth connecting column is rotatably connected to the inner diameter of the rotating hole, and a supporting bone is fixedly connected between opposite sides of two adjacent fourth connecting columns.

[0008] In some embodiments, the first reinforcing rib is fixedly connected to the second reinforcing rib, and the first reinforcing rib and the second reinforcing rib are both fixedly connected to the inner wall of the auxiliary rib.

[0009] In some embodiments, the connecting strip is fixedly connected to the second reinforcement member, and the connecting strip is fixedly connected to the first reinforcement member.

[0010] In some embodiments, evenly distributed limiting holes are opened on both the front and rear sides of the main rod, marbles are arranged in the limiting holes, and double-pressure spring sheets are arranged between two adjacent marbles.

[0011] In some embodiments, the double-pressure spring sheet is located inside the main rod, and the marble is slidably connected to the limiting hole.

[0012] In some embodiments, first connecting columns are fixedly connected to both sides of the inner wall of the supporting bone.

[0013] In some embodiments, sliding grooves are provided on both sides of the main ribs, and the sliding grooves are slidably connected to the first connecting column.

[0014] In some embodiments, an umbrella cap is fixedly connected to the top of the reinforcement member.

[0015] Working principle: First, fix the reinforcement piece to the top of the main pole by welding, then fix the four first connecting pieces to the reinforcement piece by welding, further clamp the main ribs on the outside of the reinforcement piece, then insert the two third connecting columns into the corresponding main ribs, and the bottom side of the auxiliary ribs is connected to the second connecting piece through the second connecting column, and further the second connecting piece is fixed to the sliding sleeve by welding, and the main ribs are opened or closed by sliding the sliding sleeve up and down on the surface of the main pole, and when the main ribs are opened, the sliding sleeve drives the second connecting piece to move upward, and the second connecting piece and the auxiliary ribs rotate to change the angle of the auxiliary ribs, and the auxiliary ribs lift the main ribs. , further, with the change of the angle of the auxiliary rib, the outer side of the supporting rib slides outward in the sliding groove on the main rib until the sliding sleeve is limited by the marbles, and the expansion degree of the main rib to the auxiliary rib is fixed, and the position and angle of the supporting rib are also limited. When encountering strong winds and bending the main rib upward to cause the rib to flip, that is, flip upward in the opposite direction, the outer side of the supporting rib uses the auxiliary rib as a support point to provide a certain pulling force for the outer side of the main rib to prevent the main rib from flipping upward. When shrinking, it is only necessary to press the corresponding marbles so that two marbles at the same level are separated from the sliding sleeve, and the marbles have the rebound force of the double-pressure spring sheet, so that the marbles will not fall out of the limiting hole.

[0016] The present invention provides a reinforced umbrella rib structure, which has the following beneficial effects:

[0017] 1. The present invention uses the first reinforcing rib, the second reinforcing rib, the first reinforcing member, the connecting strip and the second reinforcing member to reinforce the inside of the main rib and the auxiliary rib when the main rib and the auxiliary rib are opened based on the principle that the triangle has stability, so that the main rib and the auxiliary rib have stronger supporting force, thereby avoiding the problem of rib breakage due to weight when encountering strong winds, heavy rains and heavy snow.

[0018] 2. The present invention uses the support bone to pull the main rib when the main rib and the auxiliary rib are opened. The support bone uses the auxiliary rib as a support point, and then the outer side of the support bone is clamped in the slide groove of the main rib by using the first connecting column, so that the main rib generates a support point between the support bone and the auxiliary rib, thereby avoiding the problem that the rib is bent upward and caused to flip over, thereby preventing the rib from being deformed and bent and damaged.
