TECHNICAL FIELD
[0001] The utility model relates to the field of canopy, especially a canopy cloth tensioning structure of hemispherical canopy. BACKGROUND
[0002] The hemispherical canopy is also commonly known as a half-dome tent, which is a temporary building with a unique hemispherical shape. The frame is usually made of aluminum alloy or steel, which is light, strong and durable. The unique hemispherical design not only looks beautiful, but also helps to disperse pressure and enhance stability.
[0003] Because the top of the hemispherical canopy is a curved surface structure, this shape requires the canopy cloth to be evenly covered on the entire curved surface. However, the current fixing method of the canopy cloth is to fix multiple fixing points by bolts. However, due to the non-adjustability of the bolts, it is difficult to ensure that the tension applied by each bolt is completely consistent when the canopy cloth is fixed at multiple points. Due to uneven tension, the canopy cloth may appear high on one side and low on the other side. This unevenness not only affects the appearance, but also leads to a decrease in the structural stability of the canopy. SUMMARY
[0004] To solve the above technical problems, the utility model provides a canopy cloth tensioning structure of hemispherical canopy, which aims to solve the problem that the canopy cloth may appear high on one side and low on the other side. This unevenness not only affects the appearance, but also leads to a decrease in the structural stability of the canopy.
[0005] The technical solution of the utility model to solve the above technical problems is:
[0006] A canopy cloth tensioning structure of hemispherical canopy, comprising a canopy frame, the bottom of the canopy frame is provided with a plurality of connecting frames, the bottom of the connecting frame is provided with a fixed bottom plate, further comprising a tensioning rod and a movable plate, one side of the connecting frame is provided with a fixed cavity, one side of the fixed cavity is provided with a fixed plate, one end of the tensioning rod is provided with a fixed hook, the fixed hook is hooked with the fixed plate, the other end of the tensioning rod is provided with an adjusting end, the inside of the movable plate is provided with an adjusting hole, the adjusting end is in sliding fit with the adjusting hole, the outside of the adjusting end is threadedly connected with an adjusting nut, the adjusting nut is located above the movable plate, so that the adjusting nut is in contact with the movable plate, one side of the movable plate is provided with a fixed part, the fixed part is used for connecting with the canopy cloth.
[0007] When the tension of the tarpaulin needs to be adjusted, the fixing part is used to connect with the tarpaulin, and the fixing hook is hooked with the fixing plate. At this time, the movable plate and the fixing hook will be pulled upward by the tarpaulin, causing the movable plate to abut against the adjusting nut. The fixing hook will remain hooked with the fixing plate. When the adjusting nut is turned downward, the adjusting nut will drive the movable plate to move downward. The fixing part of the movable plate will pull the tarpaulin downward to tighten it. If the adjusting nut is turned upward, the movable plate will move upward because it has upward movement space. The upward movement of the movable plate will cause the fixing part to relax the tension on the tarpaulin. The tarpaulin will correspondingly relax upward, so that the tension of the tarpaulin at each part of the tent frame can be freely adjusted, so that the tension of the tarpaulin at each part is consistent, enhancing the stability of the entire tent structure and improving its ability to resist wind loads and other external factors.
[0008] Furthermore, in this application, the fixing part includes a first clamping plate and a second clamping plate. The first clamping plate is disposed on one side of the movable plate, and the second clamping plate is movably disposed on one side of the first clamping plate. The first clamping plate and the second clamping plate are separated to form a clamping gap, which is used to accommodate the tarpaulin.
[0009] The second clamping plate is movable, meaning it can move relative to the first clamping plate to open or close the clamping interval. When the tarpaulin is placed in the clamping interval, the second clamping plate can gradually move closer to the first clamping plate, causing the clamping interval to clamp the tarpaulin and thus fix it in place. Through the clamping structure, the tarpaulin can be firmly fixed to the movable plate, preventing it from shifting or loosening under the action of external forces such as wind. Furthermore, the design of the clamping interval can accommodate tarpaulins of different thicknesses, improving the versatility of the fixing structure.
[0010] Furthermore, in this application, the first clamping plate has a plurality of first fixing holes inside, and the second clamping plate has a plurality of second fixing holes inside, with the plurality of first fixing holes corresponding to the plurality of second fixing holes respectively.
[0011] By opening a first fixing hole and a second fixing hole on the first clamping plate and the second clamping plate, when the tarpaulin is placed between the first clamping plate and the second clamping plate, the bolt passes through the second fixing hole and engages with the threaded first fixing hole, thereby firmly clamping the tarpaulin between the first clamping plate and the second clamping plate.
[0012] Furthermore, in this application, a limiting hole is provided on one side of the fixing plate, and the fixing hook is hooked to the limiting hole.
[0013] Furthermore, in this application, the fixed base plate has a fixed bottom hole inside, which is used for bolts to pass through.
[0014] Furthermore, in this application, the top of the fixed base plate is provided with a plurality of lifting columns, and one end of each lifting column is provided with a lifting ring.
[0015] Furthermore, in this application, a receiving cavity is provided on the other side of the connecting frame, and the receiving cavity is used to receive the load-bearing component.
[0016] Furthermore, in this application, the canopy frame includes multiple connecting parts, which are connected by multiple connecting beams, and the connecting frame is connected to adjacent connecting beams.
[0017] Furthermore, in this application, the connecting portion has a visible cavity, and the inner edge of the visible cavity has a plurality of mounting holes, which penetrate the outer edge of the connecting portion and correspond to the adjacent connecting beam.
[0018] Furthermore, in this application, a weight-reducing cavity is provided inside the visible cavity, and the weight-reducing cavity extends through one side of the connecting portion.
[0019] This utility model has the following beneficial effects:
[0020] When the tension of the tarpaulin needs to be adjusted, the fixing part is used to connect with the tarpaulin, and the fixing hook is hooked with the fixing plate. At this time, the movable plate and the fixing hook will be pulled upward by the tarpaulin, causing the movable plate to abut against the adjusting nut. The fixing hook will remain hooked with the fixing plate. When the adjusting nut is turned downward, the adjusting nut will drive the movable plate to move downward. The fixing part of the movable plate will pull the tarpaulin downward to tighten it. If the adjusting nut is turned upward, the movable plate will move upward because it has upward movement space. The upward movement of the movable plate will cause the fixing part to relax the tension on the tarpaulin. The tarpaulin will correspondingly relax upward, so that the tension of the tarpaulin at each part of the tent frame can be freely adjusted, so that the tension of the tarpaulin at each part is consistent, enhancing the stability of the entire tent structure and improving its ability to resist wind loads and other external factors.

[0032] Reference Figures 1-3 In some specific embodiments, a tent tensioning structure for a hemispherical tent includes a tent frame 1, with multiple connecting frames 2 at the bottom of the tent frame 1, a fixed base plate 6 at the bottom of the connecting frame 2, a tensioning rod 8, and a movable plate 18. A fixed cavity 3 is provided on one side of the connecting frame 2, and a fixed plate 4 is provided on one side of the fixed cavity 3. A fixed hook 9 is provided at one end of the tensioning rod 8, which hooks with the fixed plate 4. An adjusting end 10 is provided at the other end of the tensioning rod 8. An adjusting hole 12 is provided inside the movable plate 18, and the adjusting end 10 slides with the adjusting hole 12. An adjusting nut 11 is threaded onto the outside of the adjusting end 10. The adjusting nut 11 is located above the movable plate 18, so that the adjusting nut 11 abuts against the movable plate 18. A fixing part 27 is provided on one side of the movable plate 18, which is used to connect with the tent fabric.
[0033] With the above technical solution, when it is necessary to adjust the tension of the tarpaulin, since the fixing part 27 is used to connect with the tarpaulin and the fixing hook 9 is hooked with the fixing plate 4, the movable plate 18 and the fixing hook 9 will be pulled upward by the tarpaulin, causing the movable plate 18 to abut against the adjusting nut 11.

When the adjusting nut 11 is turned downward, the adjusting nut 11 will drive the movable plate 18 to move downward, and the fixing part 27 of the movable plate 18 will pull the tarpaulin downward. If the adjusting nut 11 is turned upward, the movable plate 18 will move upward because it has upward movement space. The upward movement of the movable plate 18 will cause the fixing part 27 to relax the tension on the tarpaulin, and the tarpaulin will correspondingly relax upward, so that the tension of the tarpaulin at each part of the tent frame 1 can be freely adjusted, so that the tension of the tarpaulin at each part is consistent, enhancing the stability of the entire tent structure and improving its ability to resist wind loads and other external factors.

[0035] Through the above technical solution, the second clamping plate 14 is movable, which means that it can move relative to the first clamping plate 13, thereby opening or closing the clamping interval 15. When the tarpaulin is placed in the clamping interval 15, the second clamping plate 14 can gradually approach the first clamping plate 13, so that the clamping interval 15 clamps the tarpaulin, thereby fixing it. Through the clamping structure, the tarpaulin can be firmly fixed on the movable plate 18, preventing it from shifting or loosening under the action of external forces such as wind. Furthermore, the design of the clamping interval 15 can adapt to tarpaulins of different thicknesses, improving the versatility of the fixing structure.

[0037] With the above technical solution, by opening the first fixing hole 16 and the second fixing hole 17 on the first clamping plate 13 and the second clamping plate 14, when the tarpaulin is placed between the first clamping plate 13 and the second clamping plate 14, the bolt passes through the second fixing hole 17 and engages with the first fixing hole 16 threadedly, thereby firmly clamping the tarpaulin between the first clamping plate 13 and the second clamping plate 14.
[0038] Reference Figure 4 In some specific embodiments, a limiting hole 5 is provided on one side of the fixing plate 4, and the fixing hook 9 is hooked to the limiting hole 5.
[0039] Through the above technical solution, the main function of the limiting hole 5 is to limit the movement range of the fixing hook 9, reduce the shaking of the fixing hook 9 during the adjustment process, and ensure that the tension rod 8 is kept in the correct position when adjusting the tension of the tent fabric, thereby improving the stability of the entire tent structure.
[0040] Reference Figures 4-6 In some specific embodiments, a fixing bottom hole 7 is provided inside the fixing base plate 6, and the fixing bottom hole 7 is used for bolts to pass through.
[0041] The above technical solution allows the design of the fixing hole 7 to allow bolts to pass through the base plate and connect with anchor points or foot bolts on the ground, thereby firmly fixing the tent to the ground.
[0042] Reference Figures 4-6 In some specific embodiments, the top of the fixed base plate 6 is provided with multiple lifting columns 24, and one end of the lifting column 24 is provided with a lifting ring 25.
[0043] Through the above technical solutions, the lifting column 24 and the lifting ring 25 enable the canopy 1 to be easily lifted and positioned during transportation and installation, thereby improving the construction efficiency.
[0044] Reference Figure 6 In some specific embodiments, a receiving cavity 26 is provided on the other side of the connecting frame 2, which is used to receive the load-bearing component.
[0045] The above technical solution allows the design of the cavity 26 to place the load-bearing components inside the connecting frame 2, which significantly enhances the stability of the tent, especially in the face of severe weather conditions, providing additional support and stability for the tent.
[0046] Reference Figures 1-3 In some specific embodiments, the canopy frame 1 includes multiple connecting parts 20, which are connected by multiple connecting beams 19 respectively, and the connecting frame 2 is connected to the adjacent connecting beams 19.
[0047] Through the above technical solution, and through the modular design of multiple connecting parts 20 and connecting beams 19, the canopy frame 1 can be flexibly assembled and disassembled. If the connecting parts 20 or connecting beams 19 are damaged, they can be replaced individually without disassembling the entire canopy frame 1, thus reducing maintenance costs.
[0048] Reference Figures 1-3 In some specific embodiments, the connecting part 20 has a visible cavity 21, and the inner edge of the visible cavity 21 has a plurality of mounting holes 22. The mounting holes 22 penetrate the outer edge of the connecting part 20 and correspond to the adjacent connecting beam 19.
[0049] Through the above technical solution, the design of the visible cavity 21 allows technicians to directly observe the internal condition of the connection part 20, which facilitates checking whether the connection is firm and whether there is any damage or wear.
[0050] Reference Figures 1-3 In some specific embodiments, a weight-reducing cavity 23 is provided inside the visible cavity 21, and the weight-reducing cavity 23 penetrates one side of the connecting part 20.
[0051] Through the above technical solution, the design of the weight-reducing cavity 23 enables the use of materials to be reduced and costs to be lowered while maintaining the structural strength of the connection part 20; and when the tent is exposed to direct sunlight, the weight-reducing cavity 23 helps to disperse and reduce the heat accumulated inside, maintaining the temperature balance of the tent frame 1.
