Description
Technical Field
[0001] The utility model relates to the technical field of umbrellas, and particularly relates to an umbrella rib for preventing rainwater from accumulating on the umbrella surface. Background Art
[0002] An umbrella is a commonly used tool for people to avoid rain. Its main structure consists of an umbrella surface and umbrella ribs. The umbrella surface is used to block rainwater or sunlight, while the umbrella ribs play a role in supporting the umbrella surface and guiding the opening and closing of the umbrella surface. The umbrella ribs are made of metal or fiber materials with relatively high strength and are configured with different numbers according to the size of the umbrella surface, so as to ensure sufficient support in strong wind or heavy rain environments to prevent the umbrella surface from collapsing, so that the umbrella surface of the umbrella can always maintain a certain shape to block rainwater or sunlight.
[0003] Although the above-mentioned prior art can solve corresponding technical problems, there are still certain defects: after the existing metal umbrella ribs are used on rainy days, due to the rainwater on rainy days falling on the umbrella surface, the umbrella surface becomes wet. Then, when the umbrella is put away, a large amount of rainwater will accumulate on the umbrella surface. When the umbrella is opened again and the umbrella ribs drive the umbrella surface to open quickly, it is easy to cause the accumulated rainwater on the umbrella surface to spray outwards and wet the user, and the umbrella ribs are also easily directly contacted with the splashing accumulated rainwater and rust, affecting the service life of the umbrella ribs. Summary of the Utility Model
[0004] The purpose of the utility model is to provide an umbrella rib that can prevent rainwater from accumulating on the umbrella surface, prevent water droplets from spraying everywhere when opening the umbrella, and has a relatively long service life in view of the defects and deficiencies of the prior art.
[0005] To achieve the above purpose, the utility model adopts the following technical solutions: an umbrella rib for preventing rainwater from accumulating on the umbrella surface, including a connecting handle, a first umbrella rib whose one end is movably clamped with the top of the connecting handle, and an upper push handle whose one end is movably clamped with the first umbrella rib. The other end of the upper push handle is slidably connected with the outer wall of the connecting handle. The other end of the first umbrella rib is provided with an extended umbrella rib. The extended umbrella rib includes a second umbrella rib whose one end is movably clamped with the other end of the first umbrella rib and a third umbrella rib movably clamped at the other end of the second umbrella rib. It is characterized in that: the first umbrella rib and the second umbrella rib are movably clamped with each other through a vibration clamping ring, and the second umbrella rib and the third umbrella rib are movably clamped with each other through a buffer clamping ring.
[0006] Further improvement is: the buffer clamping ring includes an outer layer torsion ring connected with the third umbrella rib and an inner core ring movably clamped inside the outer layer torsion ring and connected with the second umbrella rib. The outer wall of the inner core ring is provided with an inner pressure block, the inner wall of the outer layer torsion ring is provided with a buffer block, and the inner wall of the buffer block is provided with a sliding groove. One end of the top of the inner pressure block is slidably connected with the inner wall of the sliding groove.
[0007] Further improvement: A blocking tray is also provided on the inner wall of the sliding groove and is slidably connected to the inner wall of the sliding groove.
[0008] Further improvement: A decompression spring is provided between one side of the blocking tray and the inner wall of the sliding groove.
[0009] Further improvement: The vibration snap ring includes an outer layer circle connected to the second umbrella rib and a fixed core disposed inside the outer layer circle and movably engaged with the outer layer circle. The outer wall of the fixed core is connected to the first umbrella rib. A plurality of vibration tubes are provided on the inner wall of the outer layer circle, and a sliding ring is provided between the vibration tubes and the fixed core.
[0010] Further improvement: The vibration tube includes a tube wall disposed between the sliding ring and the outer layer circle and an impact ball disposed inside the tube wall.

[0020] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0021] Refer to Figures 1-4 As shown, the technical solution adopted in this specific implementation mode is: As shown in Figure 1 , a rib for preventing rainwater accumulation on the umbrella surface includes a connecting handle 1, a first rib 3 whose one end is movably clamped with the top of the connecting handle 1, and an upper push handle 2 whose one end is movably clamped with the first rib 3. The other end of the upper push handle 2 is slidably connected to the outer wall of the connecting handle 1. The other end of the first rib 3 is provided with an extended rib. The extended rib includes a second rib 4 whose one end is movably clamped with the other end of the first rib 3 and a third rib 5 movably clamped at the other end of the second rib 4. It is characterized in that: The first rib 3 and the second rib 4 are movably clamped with each other through a vibrating snap ring 6, and the second rib 4 and the third rib 5 are movably clamped with each other through a buffer snap ring 7. When the present utility model is used, the connecting handle 1 is connected to the middle rod of the umbrella, and the first rib 3, the second rib 4 and the third rib 5 are covered with an umbrella cloth above. When the umbrella is opened, the upper push handle 2 is pushed upwards, so that the upper push handle 2 can move upwards along the connecting handle 1, thereby pushing the first rib 3 to open along the top of the connecting handle 1, and then the umbrella cloth is unfolded. And cooperate with the pulling force of the umbrella cloth to make the second rib 4 and the third rib 5 twist, and cooperate with the buffer snap ring 7 to buffer the torsion force during the expansion process of the second rib 4 and the third rib 5, and make the expansion process not too sudden to cause accumulated water to fly everywhere, and at the same time drive the vibrating snap ring 6 to shake off the rainwater on the umbrella cloth, and then slide down from the umbrella cloth to reduce the accumulation amount of rainwater;
[0022] As Figure 2 As shown, the buffer snap ring 7 includes an outer torsion ring 21 connected to the third rib 5 and an inner core ring 22 movably engaged inside the outer torsion ring 21 and connected to the second rib 4. An inner pressing block 23 is provided on the outer wall of the inner core ring 22, and a buffer block 24 is provided on the inner wall of the outer torsion ring 21. A sliding groove is provided on the inner wall of the buffer block 24. One end of the top of the inner pressing block 23 is slidably connected to the inner wall of the sliding groove. When the third rib 5 and the second rib 4 twist, it will drive the outer torsion ring 21 and the inner core ring 22 to twist relative to each other, and then cause the inner pressing block 23 provided outside the inner core ring 22 and the buffer block 24 to slide relative to each other. If the opening speed is relatively slow, the relative movement between the buffer block 24 and the inner pressing block 23 is slow, and the inner pressing block 23 is slowly pressed into the buffer block 24, which will not affect the opening. If the opening speed is fast and sudden, friction will be generated between the inner wall of the sliding groove of the buffer block 24 and the inner pressing block 23, thereby generating a blocking force to decelerate the opening and prevent rainwater from splashing due to sudden opening;
[0023] A blocking tray 25 slidably connected to the inner wall of the sliding groove is further provided on the inner wall of the sliding groove, which is beneficial to further increase the deceleration effect on the inner pressing block 23, and further avoid the phenomenon of rainwater splashing caused by sudden opening;
[0024] A decompression spring is provided between one side of the blocking tray 25 and the inner wall of the sliding groove, which is beneficial to absorb the impact force generated by suddenly opening the umbrella, and further decelerate the opening, so as to further reduce the probability of rainwater splashing;
[0025] As Figure 3 shown, the vibration snap ring 6 includes an outer ring 31 connected to the second rib 4 and a fixed core 32 provided inside the outer ring 31 and movably engaged with the outer ring 31. The outer wall of the fixed core 32 is connected to the first rib 3. A plurality of vibration tubes 34 are provided on the inner wall of the outer ring 31. In this embodiment, there are six vibration tubes 34. A sliding ring 33 is provided between the vibration tube 34 and the fixed core 32. When the second rib 4 and the first rib 3 twist relative to each other, the outer ring 31 can be driven by the second rib 4 to rotate rapidly, thereby generating a centrifugal force applied to the vibration tube 34 to cause it to vibrate, and then outputting the vibration to the umbrella cloth through the second rib 4 to shake off the rainwater accumulated on the umbrella cloth;
[0026] As Figure 4 shown, the vibration tube 34 includes a tube wall 41 provided between the sliding ring 33 and the outer ring 31 and an impact ball 45 provided inside the tube wall 41. After the centrifugal force is applied to the vibration tube 34, the impact ball 45 moves rapidly along the tube wall 41, and then impacts the inner wall of the tube wall 41 after moving to the high point, generating vibration;
[0027] The vibrating tube 34 further includes a collision block 43 disposed at the top inner wall of the tube wall 41, which is beneficial to obtaining a better collision effect and collision strength with the impact ball 45 through the protruding collision block 43, thereby generating a greater vibration intensity and having a better effect on removing the accumulated water on the umbrella cloth;
[0028] A number of hemispherical collision bumps 44 are also provided on the inner wall of the tube wall 41. In this embodiment, there are ten of them, which are beneficial to generating more collisions during the movement of the impact ball 45, thereby obtaining a higher jitter frequency, and further enabling the accumulated water on the umbrella cloth to be shaken off more thoroughly;
[0029] An elastic sheet 42 is further provided at the bottom inner wall of the tube wall 41, which is beneficial to obtaining a rebound when the impact ball 45 falls, and then contacting the collision bump 44 again after the rebound, thereby obtaining more jitter times, and enabling the accumulated water on the umbrella cloth to be shaken off better under the influence of more jitter times.
[0030] The working principle of the present utility model: When the present utility model is in use, the connecting handle 1 is connected to the middle rod of the umbrella, and the umbrella cloth is laid above the first umbrella rib 3, the second umbrella rib 4 and the third umbrella rib 5. When the umbrella is opened, the push handle 2 is pushed upward, and the push handle 2 can move upward along the connecting handle 1, thereby pushing the first umbrella rib 3 to open along the top of the connecting handle 1, and then the umbrella cloth is opened, and the second umbrella rib 4 and the third umbrella rib 5 are twisted by the reverse pulling force of the umbrella cloth. The buffer snap ring 7 is used to buffer the torsion during the expansion of the second umbrella rib 4 and the third umbrella rib 5, and make the expansion process not too sudden to cause the accumulated water to splash everywhere. At the same time, the vibration snap ring 6 is driven to shake off the rainwater on the umbrella cloth, and then the rainwater slides down from the umbrella cloth to reduce the accumulation amount of the rainwater. When the third umbrella rib 5 and the second umbrella rib 4 are twisted, the outer layer torsion ring 21 and the inner core ring 22 will be driven to twist with each other, and then the inner pressure block 23 and the buffer block 24 provided outside the inner core ring 22 will slide relative to each other. If the opening speed is relatively slow, the relative movement between the buffer block 24 and the inner pressure block 23 will be relatively slow, and the inner pressure block 23 will slowly press into the buffer block 24 without affecting the opening. If the opening speed is fast and the opening is sudden, the inner wall of the sliding groove on the inner wall of the buffer block 24 will generate friction with the inner pressure block 23, thereby generating a blocking force to decelerate the opening and avoid the rainwater splashing caused by sudden opening. When the second umbrella rib 4 and the first umbrella rib 3 twist with each other, the outer layer ring 31 can be driven by the second umbrella rib 4 to rotate rapidly at this time, thereby generating a centrifugal force applied to the vibrating tube 34. After the centrifugal force is applied to the vibrating tube 34, the impact ball 45 moves rapidly along the tube wall 41, and then impacts the inner wall of the tube wall 41 after moving to the high point, generating vibration, and then the vibration is output to the umbrella cloth through the second umbrella rib 4 to shake off the accumulated rainwater on the umbrella cloth, avoiding the remaining raindrops and preventing the raindrops from directly contacting the umbrella ribs to cause rust, and at the same time avoiding the rainwater spraying around during the opening process to wet the user.
