[0002] Umbrellas are an indispensable item in our daily lives, often accompanying us through wind and rain. However, as they are used for a long time, umbrellas inevitably develop problems such as torn canopies or broken ribs. Usually, people simply discard damaged umbrellas and buy new ones. But some umbrellas hold various meanings for their owners, making them reluctant to throw them away. They then seek out craftsmen who can repair umbrellas. However, when replacing the umbrella canopy, the craftsman needs to first open the umbrella and then remove the screws connecting the canopy and the ribs one by one. An open umbrella is difficult to control, requiring the craftsman to control the ribs with one hand and remove the screws with the other, thus increasing the difficulty and reducing the efficiency of replacing the canopy.

[0017] Reference Figures 1 to 4 As shown, this utility model provides a metal fastening device for quick replacement of umbrella canopy, including: a horizontal plate 5, with a main telescopic rod 4 and a secondary telescopic rod 10 fixedly connected to both ends of the lower surface of the horizontal plate 5, and the lower ends of the main telescopic rod 4 and the secondary telescopic rod 10 slidably connected to the main column 2 and the secondary column 11, respectively. The lower surfaces of the main column 2 and the secondary column 11 are both fixedly connected to a base plate 1, and the surface of the horizontal plate 5 is respectively provided with a fitting groove 6 and an adjustment groove 9. The umbrella body 3 is movably connected to the fitting groove 6, and a storage groove is provided on the side of the cavity of the fitting groove 6 near the adjustment groove 9. The main screw 8 is movably connected to the storage groove through a bearing. The moving block 7 is slidably connected to the storage groove through the screwed main screw 8. At the same time, the end face of the moving block 7 is fixedly connected to a moving plate 14. A main sliding groove is provided in the moving plate 14, and a secondary screw 16 is movably connected to the main sliding groove through a bearing. The two ends of the secondary screw 16 are symmetrically screwed with positioning plates 15.

[0018] In this embodiment, the user pulls the main telescopic rod 4 and the auxiliary telescopic rod 10, which are fixedly connected, upwards simultaneously via the horizontal plate 5. During the upward movement of the main telescopic rod 4, the inclined surfaces of the limiting groove and the limiting block push the abutment plate 12 to compress the spring in the buffer groove. After the horizontal plate 5, the main telescopic rod 4, and the auxiliary telescopic rod 10 have moved to the appropriate positions, a corresponding height fine-tuning is performed so that the abutment plate 12 can embed the limiting block into the corresponding limiting groove under the action of the compressed spring, thereby achieving a fixed connection between the main telescopic rod 4 and the main column 2 and preventing unexpected changes in the height of the horizontal plate 5. Then, the umbrella body 3 is opened, and the handle at the end of the umbrella body 3 is inserted into the groove opened in the horizontal plate 5. Inside the groove 6, the main screw 8 is rotated, which pushes the screwed moving block 7 to move. The moving block 7 can then initially position and clamp the tail end of the umbrella body 3 through the moving plate 14. Then, the auxiliary screw 16 is rotated, and the positioning plates 15 screwed at both ends of the auxiliary screw 16 can move in the opposite direction synchronously. This allows the positioning plates 15 to clamp both sides of the tail end of the umbrella body 3, thus achieving a stable connection between the horizontal plate 5 and the umbrella body 3. The umbrella body 3 hanging upside down allows the user to free their hands and effectively prevents the umbrella body 3 from accidentally shaking during the replacement of the umbrella cloth. This reduces the difficulty of replacing the umbrella cloth and improves the efficiency of replacing the umbrella cloth.

[0019] In a preferred embodiment, the horizontal plate 5 has a long strip structure, and the fitting groove 6 and the adjustment groove 9 opened on the surface of the horizontal plate 5 are both rectangular structures. The storage groove opened on the side of the fitting groove 6 has a cuboid structure, and the size of the storage groove and the moving block 7 are matched. At the same time, the tail end of the main screw 8 is located in the adjustment groove 9, and the moving plate 14 fixedly connected to the end face of the moving block 7 has a rectangular structure.

[0020] In this embodiment, as Figure 1 and Figure 2 The opening of the fitting groove 6 makes it easy to initially position the tail end of the umbrella body 3, so that the umbrella body 3 can be in an upside-down and suspended state. The opening of the adjustment groove 9 makes it easy for the user to rotate the main screw 8, improving the flexibility of the device when in use.

[0021] In a preferred embodiment, the main slide groove on the surface of the movable plate 14 has an elongated structure, and two sets of guide rods 17 are symmetrically connected inside the main slide groove. Both sets of guide rods 17 have a cylindrical structure and are located on both sides of the auxiliary lead screw 16. At the same time, the movable plate 14 and the main slide groove are combined to form a U-shaped structure.

[0022] In this embodiment, as Figure 1 and Figure 4 The guide rod 17 can help enhance the stability of the positioning plate 15 when it moves, and can also help enhance the stability of the connection between the positioning plate 15 and the moving plate 14, reducing the probability of the auxiliary lead screw 16 bending and deforming unexpectedly, and reducing the probability of the device malfunctioning.

[0023] As a preferred embodiment, there are two sets of positioning plates 15. Both sets of positioning plates 15 have a convex shape structure, and the size of the protrusion of the positioning plate 15 is adapted to the size of the main slide groove. At the same time, the position of the protrusion of the positioning plate 15 relative to the guide rod 17 and the auxiliary lead screw 16 is respectively provided with guide holes and screw holes. The moving plate 14 and the positioning plate 15 are combined together to form a Π-shaped structure.

[0024] In this embodiment, as Figure 1 , Figure 2 and Figure 4 The structural design of the positioning plate 15 can not only help enhance the stability of the positioning plate 15 when it moves on the surface of the moving plate 14, but also effectively limit the range of motion of the tail end of the umbrella body 3, thereby enhancing the fixing effect of the device on the umbrella body 3.

[0025] In a preferred embodiment, the main telescopic rod 4 and the auxiliary telescopic rod 10 are both rectangular, while the main column 2 and the auxiliary column 11 are both cylindrical. The lower surfaces of the main column 2 and the auxiliary column 11 are respectively fixedly connected to a set of base plates 1, both of which are rectangular. At the same time, the main column 2 and the auxiliary column 11 are perpendicular to the corresponding base plates 1.

[0026] In this embodiment, as Figure 1 and Figure 2 The horizontal plate 5, main column 2, secondary column 11, main telescopic rod 4, and secondary telescopic rod 10 are all made of aluminum alloy, which helps to reduce the overall weight of the device. At the same time, the internal dimensions of the main telescopic rod 4 and the main column 2 are matched, and the internal dimensions of the secondary telescopic rod 10 and the secondary column 11 are matched, which helps to enhance the stability of the overall structure after the device is deployed. The base plate 1 is made of stainless steel, which helps to enhance the stability of the device after it is placed.

[0027] In a preferred embodiment, a buffer groove is provided at the upper end of the inner cavity of the main column 2. The buffer groove has a square structure, and the abutment plate 12 is slidably connected in the buffer groove by a fixedly connected spring. The dimensions of the abutment plate 12 and the buffer groove are matched, and the pull rod 13 is fixedly connected to the side of the abutment plate 12 near the spring. The pull rod 13 has a cylindrical structure, and a through hole is provided on the surface of the buffer groove relative to the position of the pull rod 13.

[0028] In this embodiment, as Figure 1 , Figure 2 and Figure 3 The buffer groove and the abutment plate 12 are matched in size, which helps to enhance the stability of the abutment plate 12 when it moves. Moreover, the two ends of the spring are fixedly connected to the surfaces of the abutment plate 12 and the buffer groove, which can effectively prevent the abutment plate 12 from accidentally dislodging from the buffer groove. At the same time, the setting of the pull rod 13 allows the user to easily adjust the position of the abutment plate 12, thereby removing the restriction between the main column 2 and the main telescopic rod 4, so that the device can be easily folded and stored, reducing its size.

[0029] In a preferred embodiment, multiple sets of limiting blocks are fixedly connected at equal intervals on the surface of the abutment plate 12. The multiple sets of limiting blocks are all in the form of right-angled triangular prisms. On the side of the main telescopic rod 4 near the limiting blocks, multiple sets of limiting grooves are opened at equal intervals along the length direction. At the same time, the dimensions of the limiting blocks and the limiting grooves are compatible.

[0030] In this embodiment, as Figure 1 , Figure 2 and Figure 3 The dimensions of the limiting block and the limiting groove are matched, which can enhance the stability of the connection between the main column 2 and the main telescopic rod 4. Furthermore, the inclined surfaces between the limiting block and the limiting groove are parallel to each other, thus reducing the difficulty of moving the main telescopic rod 4 upward and ensuring that the device can be easily deployed.
