Description

Technical Field

[0001] This utility model relates to the field of sun protection, and in particular to a sun umbrella with a detachable canopy. Background Technology

[0002] A sun umbrella is a portable outdoor tool designed to block sunlight and ultraviolet rays. It mainly provides shade by physically shielding people and is widely used in daily life, outdoor activities and professional scenarios. Its core function is to reduce the intensity of solar radiation on the human body through physical shielding and the properties of sun-protective materials. At the same time, it achieves a cooling effect by using the heat insulation properties of the materials, providing users with efficient sun protection.

[0003] When using sun umbrellas for daily outdoor activities, the umbrella surface easily gets dirty with mud, tree sap, and beverage stains, which need to be cleaned in time. However, overall cleaning is time-consuming and laborious. Traditional sun umbrellas have the canopy and ribs fixedly connected, so the entire umbrella needs to be cleaned. It is difficult to clean stubborn stains deep into the folds or crevices, and this may even cause the metal ribs to rust. In addition, these dirt and dirt will adhere to the umbrella surface for a long time, covering the sun protection coating and gradually weakening the sun protection effect. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, which makes it difficult to clean the umbrella surface of the stains generated during use, the technical problem of this utility model is to provide a convenient sunshade with a detachable umbrella surface.

[0005] The technical implementation scheme of this utility model is as follows: a detachable parasol includes umbrella ribs, an umbrella surface at the top of the umbrella ribs, a fixed ring at the center of the umbrella surface, a locking ring at the bottom of the fixed ring and an umbrella rib, a first screw fixedly connected at the center of the top of the umbrella ribs, a hole in the center of the fixed ring and fitted onto the first screw, a first nut threadedly connected to the top of the first screw, the first nut being used to axially press the fixed ring against the top of the umbrella ribs, and five disassembly mechanisms evenly distributed in a circle around the first screw between the umbrella ribs and the umbrella surface, the disassembly mechanisms being used to achieve rapid separation and fixation of the umbrella ribs and the edge area of ​​the umbrella surface.

[0006] More preferably, the disassembly mechanism includes a support base, which is fixedly connected to the middle of the umbrella rib. A sliding rod is provided inside the support base. A fixing frame is fixedly connected to the middle of the support base. A hook is rotatably connected to the fixing frame. A first spring is fixedly connected to the left side of the support base, located below and contacting the hook to the left. A second spring is fixedly connected to the right side of the support base, located below and to the right of the hook. A pushing rod for pushing the hook is slidably connected to the sliding rod inside the support base. The bottom of the pushing rod contacts the upper left side of the hook. A locking ring is fixedly connected inside the umbrella canopy, corresponding to the position of the hook. The hook restricts the circumferential displacement of the locking ring and, in conjunction with the fixing ring, completes the positioning of the umbrella canopy. The first spring provides the elastic force to rotate the hook around the fixing frame.

[0007] More preferably, it also includes a sliding rod, which is slidably connected to the bottom of the umbrella rib. The sliding rod has a through hole, and three through holes are evenly distributed along the axial direction at the bottom of the umbrella rib. The umbrella rib and the sliding rod are connected by a second screw threadedly. The second screw passes through the through hole corresponding to the bottom of the umbrella rib and the sliding rod, and the right side of the second screw is threadedly connected to a second nut.

[0008] More preferably, it also includes a protective cover, the top of which is engaged with the protective cover.

[0009] More preferably, it also includes a blackout curtain, the bottom end of which is connected to the blackout curtain via a zipper.

[0010] More preferably, it also includes a cushioning pad, which is fixedly connected to the middle of the umbrella rib.

[0011] More preferably, it also includes a limiting rod, wherein the umbrella rib and the sliding rod are symmetrically and fixedly connected with the limiting rod, and the limiting rod has a function to limit the maximum extension and retraction stroke of the sliding rod.

[0012] This utility model has the following advantages: By pressing the push rod, it moves downward on the support base, pushing the hook to rotate around the fixed frame. During this process, the push rod compresses the first spring through the hook, and at the same time, the hook disengages from the locking ring. The second spring extends to assist the hook in completely separating. Then, the first nut is rotated and screwed upward along the first screw to completely remove the first nut. Subsequently, the umbrella canopy can be removed as a whole. The separated umbrella canopy can be fully unfolded and laid flat, which facilitates deep cleaning of wrinkles and gaps, thereby extending the service life and reducing maintenance costs.

[0013] After loosening the second nut by turning it, pull out the second screw. The umbrella ribs can then slide up and down inside the sliding rod. Slide the umbrella ribs to the appropriate height inside the sliding rod, align the umbrella ribs with the through holes of the sliding rod, insert the second screw, and tighten the second nut. This allows for personalized adjustment of the sun umbrella height and improves ease of operation. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in the present invention based on the specific circumstances.

[0020] Example: A sun umbrella with a detachable canopy, such as Figure 1-4As shown, the umbrella includes an umbrella rib 1, an umbrella canopy 2, a fixing ring 3, a first screw 4, a first nut 5, and a disassembly mechanism 6. The umbrella canopy 2 is located on the top of the umbrella rib 1. The center of the umbrella canopy 2 is fixedly connected to the fixing ring 3. The bottom of the fixing ring 3 is engaged with the umbrella rib 1. The first screw 4 is fixedly connected to the center of the top of the umbrella rib 1. The fixing ring 3 has a central hole and is fitted onto the first screw 4. The first nut 5 is threaded onto the top of the first screw 4. The first nut 5 is used to axially press the fixing ring 3 onto the top of the umbrella rib 1. Five disassembly mechanisms 6 are evenly distributed in a circle between the umbrella rib 1 and the umbrella canopy 2, with the first screw 4 as the center. The disassembly mechanisms 6 are used to quickly separate and fix the edge areas of the umbrella rib 1 and the umbrella canopy 2. The disassembly mechanism 6 includes a support base 601, a fixing frame 602, a hook 603, a first spring 604, a second spring 605, a push rod 606, and a locking ring 607. The support base 601 is fixedly connected to the middle of the umbrella rib 1. A sliding rod is provided inside the support base 601. The fixing frame 602 is fixedly connected to the middle of the support base 601. The hook 603 is rotatably connected to the fixing frame 602. The first spring 604 is fixedly connected to the left side inside the support base 601. The second spring 605 is fixedly connected to the right side of the support base 601, which is located below and to the left of the hook 603. A push rod 606 for pushing the hook 603 is slidably connected to a slide rod inside the support base 601. The bottom of the push rod 606 contacts the upper left side of the hook 603. A snap-fit ​​ring 607 is fixedly connected inside the umbrella surface 2, and the snap-fit ​​ring 607 corresponds to the position of the hook 603. A protective cover 10 is also included, and the top of the fixing ring 3 snaps into the protective cover 10.

[0021] When cleaning the sun umbrella after use, place the fully opened umbrella in a suitable position. First, separate the locking structure between the ends of the umbrella ribs 1 and the edge of the umbrella surface 2. Then, press the push rod 606 to make it slide downward on the support base 601 through the internal slide rod, causing the hook 603 to rotate around the fixing frame 602. The left side of the hook 603 compresses the first spring 604, and the right side of the hook 603 disengages from the locking ring 607. The first spring 604 simultaneously stores force, and the second spring 605 expands to assist the hook 603 in complete separation. Through the same operation, all the disassembly mechanisms 6 can be separated, allowing the middle of the umbrella ribs 1 to separate from the middle of the umbrella surface 2. Next, manually open the protective cover 10, which protects the fixing ring 3 and the first screw 4. Separate the protective cover 10 from the fixing ring 3, and rotate the first nut 5 along the first screw 4. Unscrew upwards to completely remove the first nut 5, and the umbrella canopy 2 can be removed. After the umbrella canopy 2 is separated from the umbrella rib 1, it can be fully unfolded and laid flat, which facilitates deep cleaning of wrinkles and gaps, extends service life, and reduces maintenance costs. When reassembly is required after cleaning, lay the umbrella canopy 2 flat on the corresponding position of the umbrella rib 1, tighten the first nut 5 to axially press the center of the umbrella canopy 2, and press the top of the umbrella canopy 2 and the umbrella rib 1 together by pressing down the fixing ring 3. Then, align the locking ring 607 in the middle of the umbrella canopy 2 with the locking hook 603 in the middle of the umbrella rib 1 and press down to drive the locking ring 607 to contact the locking hook 603, compressing the second spring 605. After releasing, the first spring 604 pushes the locking hook 603 to reset, thereby fixing the middle of the umbrella canopy 2. Through the same operation, other disassembly mechanisms 6 can be engaged. Finally, reset the locking structure between the end of the umbrella rib 1 and the edge of the umbrella canopy 2.

[0022] like Figure 1 and Figure 4 As shown, the umbrella rib 1 also includes a sliding rod 7, a second screw 8, and a second nut 9. The sliding rod 7 is slidably connected to the bottom of the umbrella rib 1. The sliding rod 7 has a through hole. Three through holes are evenly distributed along the axial direction at the bottom of the umbrella rib 1. The umbrella rib 1 and the sliding rod 7 are threadedly connected by the second screw 8. The second screw 8 passes through the through hole corresponding to the bottom of the sliding rod 7 and the umbrella rib 1. The right side of the second screw 8 is threadedly connected to the second nut 9. The second nut 9 is used to fix the umbrella rib 1 and the sliding rod 7. A limiting rod 13 is also included, which is symmetrically fixedly connected between the umbrella rib 1 and the sliding rod 7.

[0023] When adjusting the height of the parasol, loosen the second nut 9 by turning it, and pull out the second screw 8 to separate it from the umbrella rib 1 and the sliding rod 7. The bottom of the umbrella rib 1 can slide up and down inside the sliding rod 7. The limiting rod 13 moves synchronously with the umbrella rib 1 to help align the through hole of the umbrella rib 1 and the sliding rod 7 and prevent misalignment. Manually slide the umbrella rib 1 up and down until the umbrella rib 1 and the through hole of the sliding rod 7 are aligned. After determining the appropriate height, insert the second screw 8 through the through hole of the sliding rod 7 and the umbrella rib 1 and tighten the second nut 9 to fix the umbrella rib 1 and the sliding rod 7, realizing personalized adjustment of the parasol height and improving the ease of operation.

[0024] like Figure 1 and Figure 2 As shown, it also includes a blackout curtain 11, and the bottom end of the umbrella surface 2 is connected to the blackout curtain 11 via a zipper. It also includes a cushioning pad 12, which is fixedly connected to the middle of the umbrella rib 1.

[0025] During the opening of the parasol, the buffer pad 12 in the middle of the umbrella rib 1 helps to fix the opening angle of the umbrella rib 1 through friction, avoiding accidental slippage and improving operational safety; the sunshade curtain 11 installed at the edge of the umbrella surface 2 can block more ultraviolet rays entering from the side, achieving all-round sun protection.
