Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of umbrellas, and particularly relates to an umbrella with a carbon fiber umbrella bone structure that can be reversely retracted. Background Art
[0002] An umbrella is a commonly used tool for sheltering from rain. Its main structure consists of an umbrella surface and umbrella ribs. The umbrella surface is used to block rain or sunlight, while the umbrella ribs play a role in supporting the umbrella surface and guiding the opening and closing of the umbrella surface. A reversely retractable umbrella (also known as a reverse umbrella) is an innovative design umbrella with an opening and closing direction opposite to that of a traditional umbrella. Its core feature is that when the umbrella surface is retracted, it folds reversely, wrapping the wet umbrella surface inside and keeping the dry side facing out. After the umbrella is retracted, its volume is compact, the wet surface is not exposed, and it is suitable for long-term storage in places such as a car or a warehouse where dryness needs to be maintained.
[0003] Although the above-mentioned prior art can solve corresponding technical problems, there are still certain defects: After the existing reversely retractable umbrella is retracted, although the dry inner surface can face outwards and the wet surface can face inwards, there are still water droplets remaining on the wet surface. And after it is completely retracted, the wet surfaces are in contact with each other, and the gap between them becomes smaller, making it more difficult for the water droplets to drain outwards. It is easy for the water droplets to remain inside the wet surface. When the top of the umbrella is facing downwards, it is very easy for the water droplets to drip directly downwards, causing the storage space to become wet. Summary of the Invention
[0004] The purpose of the present invention is to provide an umbrella with a carbon fiber umbrella bone structure that can be reversely retracted, which is easy to drain water droplets and not prone to excessive water accumulation, aiming at the defects and deficiencies of the prior art.
[0005] To achieve the above purpose, the present invention adopts the following technical solutions: An umbrella with a carbon fiber umbrella bone structure that can be reversely retracted includes a middle rod and an umbrella bone structure fixedly welded to the middle section of the middle rod. The top of the middle rod is provided with an umbrella tip. An umbrella cloth is detachably laid on the umbrella bone structure. The umbrella bone structure includes an opening and closing structure arranged at the top of the middle rod and a first umbrella rib movably clamped to the side wall of the top of the opening and closing structure. The outer end of the first umbrella rib is also provided with a second umbrella rib that can be twisted upwards. A third umbrella rib is obliquely arranged between the middle section of the first umbrella rib and the side wall of the middle section of the opening and closing structure. Water removal joints are provided between the first umbrella rib and the second umbrella rib, between the first umbrella rib and the third umbrella rib, and between the third umbrella rib and the side wall of the middle section of the opening and closing structure.
[0006] Further improvement is that: A waterproof coating made of a superhydrophobic nano-coating material is also applied above the umbrella cloth.
[0007] Further improvement is that: The opening and closing structure includes a sliding rod welded to the top of the middle rod and a limiting plate arranged at the top of the sliding rod. A lifting push block connected to the third umbrella rib is slidably sleeved on the outer wall of the sliding rod.
[0008] Further improvements are as follows: a receiving cavity is formed in the lifting push block, and a shaking wheel with an outer wall fitting the sliding rod is installed on the inner wall of the receiving cavity.
[0009] Further improvements are as follows: a plurality of anti-slip bumps are integrally formed on the outer wall of the bottom of the lifting push block.
[0010] Further improvements are as follows: a positive magnet block is embedded in the bottom surface of the limiting plate, and a negative magnet block is embedded in the top surface of the lifting push block.
[0011] Further improvements are as follows: the water removal joint includes a central axis for connecting the umbrella ribs and a sleeve that is movably clamped and sleeved on the outer wall of the end of the central axis for connecting with the umbrella ribs or the opening and closing structure. An installation cavity is formed in the sleeve.
[0012] Further improvements are as follows: a plurality of water removal rings fixedly connected to the outer wall of the central axis are fixedly installed in the installation cavity. The water removal ring includes an installation ring fixedly connected to the inner wall of the installation cavity and a sleeve ring sleeved on the outer wall of the central axis. An impact frame with a top end fitting the inner wall of the installation ring is provided on the outer wall of the sleeve ring. A plurality of impact grooves are integrally formed on the inner wall of the installation ring. The impact frame includes a connection disk fixedly arranged on the outer wall of the sleeve ring and a telescopic frame movably clamped on the top surface of the connection disk. A heavy ball is provided at the top end of the telescopic frame. A push column is provided in a fitting manner on the bottom surface of the heavy ball. A push spring is provided between the bottom end of the push column and the top surface of the connection disk. A positioning cylinder with an inner wall fitting the outer wall of the bottom of the push column and capable of sliding relative to each other is also fixedly provided on the top surface of the connection disk.
[0013] Further improvements are as follows: the shaking wheel includes a fitting ring with an outer wall fitting the sliding rod and an inner core movably clamped in the inner wall of the fitting ring and fixedly connected to the inner wall of the receiving cavity at the end. A plurality of hemispherical contact blocks are integrally formed on the outer wall of the inner core. A plurality of flicking handles are movably clamped in the inner wall of the fitting ring. A silica gel sleeve is also sleeved on the outer wall of the fitting ring. A plurality of anti-slip grooves are integrally formed on the outer wall of the silica gel sleeve.
[0014] Further improvements are as follows: the flicking handle includes a first flicking block movably clamped in the inner wall of the contact ring and a second flicking block movably clamped at the bottom end of the first flicking block. A contact ball is fixedly installed at the bottom end of the second flicking block. A rolling cavity is integrally formed in the first flicking block. A freely rolling ball is provided on the inner wall of the rolling cavity.
[0015] After adopting the above technical solutions, the beneficial effects of the present invention are as follows: When the present invention opens and closes an umbrella, the water removal joints between the umbrella ribs twist, and then the central axis of the water removal joint, the installation cavity, and the water removal ring installed therein twist, so that the ferrule drives the impact frame to rotate along the inner wall of the installation ring. Then, when the impact frame moves to the position of the impact groove, the push spring is used to push the heavy ball connected to the telescopic frame into the impact groove, causing it to impact the impact groove, thereby making the installation ring vibrate, and then outputting the vibration to the central axis and the sleeve, thereby causing the umbrella ribs connected to the central axis and the sleeve to vibrate, and outputting the vibration to the umbrella surface on the umbrella ribs. Thus, during the process of opening and closing the umbrella, the water droplets on the surface of the umbrella surface can be shaken off. In cooperation with the waterproof coating, a large amount of the attached water droplets on the umbrella surface during the process of closing the umbrella can be shaken off and removed, effectively reducing the amount of water droplets attached to the surface of the umbrella after closing the umbrella, and preventing water droplets from leaking out when the umbrella is hung upside down and affecting the humidity of the placement space.
[0016] When the present invention opens the umbrella, the lifting push block is pushed upward. When closing the umbrella, the lifting push block is pulled downward. When lifting or lowering the lifting push block, the shaking wheel will roll on the surface of the sliding rod, and then relative rotation will occur between the inner core, the contact block, and the fitting ring, so that the swinging handle will come into contact with the contact block periodically. Thus, the contact ball at the bottom of the swinging handle will impact the contact block periodically, generating vibrations, and at the same time causing the swinging handle to swing. Then, several swinging handles can collide with each other, and at this time, high-frequency vibrations can be generated and output to the umbrella ribs and the umbrella surface through the sliding rod. In cooperation with the waterproof coating, a large amount of the attached water droplets on the umbrella surface during the process of closing and opening the umbrella can be shaken off and removed, effectively reducing the amount of water droplets attached to the surface of the umbrella after closing the umbrella, and preventing water droplets from leaking out when the umbrella is hung upside down and affecting the humidity of the placement space.

Detailed implementation manners
[0019] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0020] Refer to Figure 1-8 As shown, the technical solution adopted in this specific implementation manner is: a carbon fiber umbrella rib structure umbrella that can be reversely retracted, including a middle rod 1 and an umbrella rib structure 3 fixedly welded to the middle section of the middle rod 1. The top of the middle rod 1 is provided with an umbrella tip 4. An umbrella cloth 2 is detachably laid on the umbrella rib structure 3. The umbrella rib structure 3 includes an opening and closing structure 31 provided at the top of the middle rod 1 and a first umbrella rib 32 movably clamped to the side wall of the top of the opening and closing structure 31. The opening and closing structure 31 includes a sliding rod 311 welded to the top of the middle rod 1 and a limiting plate 314 provided at the top of the sliding rod 311. An elevating push block 312 connected to the third umbrella rib 33 is slidably sleeved on the outer wall of the sliding rod 311. The outer end of the first umbrella rib 32 is further provided with a second umbrella rib 34 that can be twisted upward. A third umbrella rib 33 is obliquely provided between the middle section of the first umbrella rib 32 and the side wall of the middle section of the opening and closing structure 31. Water removal joints 35 are provided between the first umbrella rib 32 and the second umbrella rib 34, between the first umbrella rib 32 and the third umbrella rib 33, and between the third umbrella rib 33 and the side wall of the middle section of the opening and closing structure 31. The water removal joint 35 includes a central axis 41 for connecting the umbrella ribs and a sleeve 42 movably clamped and sleeved on the outer wall of the end of the central axis 41 for connecting with the umbrella ribs or the opening and closing structure 31. An installation cavity 44 is formed in the sleeve 42. When in use, the umbrella rib structure 3 is installed in the middle section of the middle rod 1. The umbrella rib structure 3 includes an opening and closing structure 31 and a plurality of first umbrella ribs 32, second umbrella ribs 34, and third umbrella ribs 33, preferably six, and eight can also be provided to improve the wind resistance. At the same time, the first umbrella rib 32, the second umbrella rib 34, and the third umbrella rib 33 are all made of carbon fiber material, with high strength and not easily bent or broken. The umbrella cloth 2 is laid on the second umbrella rib 34, and the umbrella cloth 2 is fixed on the umbrella rib structure 3 by cooperating with the umbrella tip 4 and the end of the second umbrella rib 34. When opening the umbrella, push up the elevating push block 312 to press the third umbrella rib 33 against the first umbrella rib 32, and then make the first umbrella rib 32 open along the limiting plate 314. At the same time, under the restricting action of the umbrella cloth 2, the second umbrella rib 34 is also opened at the same time. At this time, the umbrella can be opened. When closing the umbrella, pull down the elevating push block 312, thereby pulling down the third umbrella rib 33 to pull down the first umbrella rib 32 and folding the second umbrella rib 34 in the opposite direction, thereby closing the umbrella. When opening and closing the umbrella, the central axis 41 and the sleeve 42 of the water removal joint 34 will twist relative to each other through the mutual twisting between the umbrella ribs; A waterproof coating 5 made of a superhydrophobic nano - coating material is also applied above the umbrella cloth 2. This is beneficial for making the water droplets fall on the umbrella cloth 2, and then, through the hydrophobicity of the waterproof coating 5, the water droplets can be discharged more quickly and are not easily attached to the umbrella cloth 2; An accommodation cavity 315 is formed inside the lifting push block 312. Inside the inner wall of the accommodation cavity 315, a shaking wheel 316 with an outer wall that fits the sliding rod 311 is installed. The shaking wheel 316 includes a fitting ring 23 with an outer wall that fits the sliding rod 311 and a core 21 that is movably engaged with the inner wall of the fitting ring 23 and has an end fixed to the inner wall of the accommodation cavity 315. A number of hemispherical contact blocks 22 are integrally formed on the outer wall of the core 21. A number of swinging handles 24 are movably engaged with the inner wall of the fitting ring 23. The swinging handle 24 includes a first swinging block 241 movably engaged with the inner wall of the contact ring 23 and a second swinging block 242 movably engaged with the bottom end of the first swinging block 241. A contact ball 243 is fixedly installed at the bottom end of the second swinging block 242. A rolling cavity 244 is integrally formed inside the first swinging block 241. Inside the inner wall of the rolling cavity 244, freely rolling balls 245 are provided. A silica gel sleeve 25 is also sleeved on the outer wall of the fitting ring 23. A number of anti - slip grooves 26 are integrally formed on the outer wall of the silica gel sleeve 25. When opening the umbrella, push up the lifting push block 312. When closing the umbrella, pull down the lifting push block 312. When lifting or lowering the lifting push block 312, the fitting ring 23 of the shaking wheel 316 installed in the accommodation cavity 315 inside it will roll along the surface of the sliding rod 311. At the same time, the silica gel sleeve 25 on the outer wall of the fitting ring 23 and the anti - slip grooves 26 formed on the silica gel sleeve 25 are used to increase the frictional force on the outer surface of the fitting ring 23, so that it will not slip and can rotate better. Then, a relative rotation is generated between the core 21, the contact blocks 22 and the fitting ring 23, so that the swinging handle 24 comes into contact with the contact blocks 22 periodically. Thus, the contact ball 243 at the bottom end of the swinging handle 24 impacts the contact blocks 22 periodically, generating vibrations. At the same time, the first swinging block 241 and the second swinging block 242 of the swinging handle are made to swing, so that a number of swinging handles 24 can collide with each other. And when the swinging handle 24 swings, the balls 245 in the rolling cavity 244 of the first swinging block 241 can roll in the rolling cavity 244 at the same time and collide with the inner wall of the rolling cavity 244, generating additional vibrations. At this time, high - frequency vibrations can be generated and output to the umbrella ribs and the umbrella cloth 2 through the sliding rod 311. Combined with the waterproof coating 5, a large number of attached water droplets on the umbrella surface during the umbrella - closing and umbrella - opening processes can be shaken off and cleared, effectively reducing the amount of water droplets attached to the surface of the umbrella after closing the umbrella and preventing water droplets from leaking out when hanging the umbrella upside down, which may affect the humidity of the placement space; A number of anti - slip bumps 317 are integrally formed on the bottom outer wall of the lifting push block 312, which is beneficial for increasing the frictional force between the hand and the lifting push block 312 when pushing up and pulling down, and thus preventing slipping and affecting the force transmission; A positive magnet block 318 is embedded in the bottom surface of the limit plate 314, and a negative magnet block 319 is embedded in the top surface of the lifting push block 312, which is beneficial to making the upward push more labor-saving by the suction force of the positive magnet block 318 and the negative magnet block 319 when opening the umbrella; A number of water removal rings 43 fixedly connected to the outer wall of the central shaft 41 are fixedly installed in the installation cavity 44. The water removal ring 43 includes an installation ring 432 fixedly connected to the inner wall of the installation cavity 44 and a sleeve ring 431 sleeved on the outer wall of the central shaft 41. An impact frame 434 with its top end fitting the inner wall of the installation ring 432 is provided on the outer wall of the sleeve ring 431. A number of impact grooves 433 are integrally formed on the inner wall of the installation ring 432. The impact frame 434 includes a connection disk 51 fixedly arranged on the outer wall of the sleeve ring 431 and a telescopic frame 52 movably clamped on the top surface of the connection disk 51. A heavy ball 53 is provided at the top end of the telescopic frame 52. A push column 54 is fitted on the bottom surface of the heavy ball 53. A push spring 56 is provided between the bottom end of the push column 54 and the top surface of the connection disk 51. A positioning cylinder 55 with its inner wall fitting and slidable with the outer wall of the bottom of the push column 54 is also fixedly provided on the top surface of the connection disk 51. When opening and closing the umbrella, the water removal joint 35 between the umbrella ribs generates torsion, and then the central shaft 41 of the water removal joint 35, the installation cavity 44 and the water removal ring 43 installed therein generate torsion. Thus, the sleeve ring 431 drives the impact frame 434 to rotate along the inner wall of the installation ring 432. Then, when the impact frame 434 moves to the position of the impact groove 433, the heavy ball 53 connected to the telescopic frame 52 is pushed into the impact groove 433 by the push spring 56 to impact the impact groove 433, thereby causing the installation ring 432 to vibrate. Then, the vibration is output to the central shaft 41 and the sleeve 42, and thus the umbrella ribs connected to the central shaft 41 and the sleeve 42 generate vibration and the vibration is output to the umbrella cloth 2 on the umbrella ribs. Thus, during the process of opening and closing the umbrella, the water droplets on the surface of the umbrella cloth 2 can be shaken off. Cooperating with the waterproof coating 5, a large amount of the attached water droplets on the umbrella surface during the process of closing the umbrella can be shaken off and removed, effectively reducing the amount of water droplets attached to the surface of the umbrella after closing the umbrella and preventing water droplets from leaking out when hanging the umbrella upside down and affecting the humidity of the placement space.
[0021] Working principle of the present invention: When the present invention is in use, an umbrella rib structure 3 is installed in the middle section of the middle rod 1. The umbrella rib structure 3 includes an opening and closing structure 31 and several first umbrella ribs 32, second umbrella ribs 34 and third umbrella ribs 33. Preferably, there are six, and eight can also be provided to improve the wind resistance. At the same time, the first umbrella ribs 32, second umbrella ribs 34 and third umbrella ribs 33 are all made of carbon fiber material, which has high strength and is not easy to bend and break. An umbrella cloth 2 is laid on the second umbrella rib 34, and the umbrella cloth 2 is fixed on the umbrella rib structure 3 by the cooperation of the umbrella tip 4 and the end of the second umbrella rib 34. When opening the umbrella, push up the lifting push block 312, so that the third umbrella rib 33 presses the first umbrella rib 32 upwards, and then the first umbrella rib 32 opens along the limiting plate 314. At the same time, under the restricting action of the umbrella cloth 2, the second umbrella rib 34 also opens simultaneously. At this time, the umbrella can be opened. When closing the umbrella, pull down the lifting push block 312, so that the third umbrella rib 33 pulls down the first umbrella rib 32 and makes the second umbrella rib 34 fold in the opposite direction, thereby closing the umbrella. When opening and closing the umbrella, the mutual twisting between the umbrella ribs will cause the central axis 41 and the sleeve 42 of the water removal joint 34 to twist with each other.
