Description

Technical Field

[0001] This utility model belongs to the technical field of closed connection and fixed installation of air ribs, specifically relating to a high-pressure air rib end clamp. Background Technology

[0002] The main body of the inflatable structure is made of flexible material, which can be quickly formed as a whole during inflation and tightly packaged for storage and transportation after deflation. The packaging is small in size and lightweight, and the deployment and retrieval speed is extremely fast, making it widely used in various inflatable models and tents with large expansion ratios. Ordinary low-pressure inflatable structures have weak rigidity and strength, and low load-bearing capacity, usually only suitable for small tents and other inflatable structures. They also require continuous inflation to maintain the internal air pressure and load-bearing capacity. High-pressure inflatable structures can adapt to the use of large-span, high-load-bearing, and wind-resistant inflatable tents in outdoor conditions. They can also make the air ribs thinner and fewer, effectively reducing the number of air ribs and the overall weight and volume of the equipment. However, in engineering practice, the sealing devices and technologies at the ends of these large-span high-pressure air rib structures are difficult to effectively seal the high-pressure gas, leading to air rib leakage and structural collapse. Furthermore, the sealing devices at the ends of the external air ribs may detach and fly away under the pressure of the internal high-pressure gas, causing injury and threatening property safety.

[0003] Chinese patent application CN219281414U, entitled "High-Pressure Inflatable Tent No-Drill Air Column Clamp," includes a first clamping plate, a second clamping plate, an upper fastening bolt, and a lower fastening bolt. The upper portions of the first and second clamping plates have mating clamping surfaces. The upper fastening bolt passes through the upper portions of the first and second clamping plates to fasten them together. A connecting beam is located in the middle of the first clamping plate. The upper and lower sides of the connecting beam have a first through-hole and a second through-hole, respectively. The lower fastening bolt passes through the second clamping plate and connects to a threaded hole on the first clamping plate. This patent application's clamp uses clamping surfaces to clamp the air ribs. During use, the clamp is subjected to high pressure and a force that could cause it to open, posing a risk of it being forced open. Furthermore, the installation process is complex.

The structure is simple and can be quickly installed.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] Firstly, this utility model provides a high-pressure pneumatic rib end clamp.

[0008] Optionally, the first clamping plate of the fixture includes a first base plate, one end of which is connected to a first connecting plate and the other end of which is connected to a first upright plate; the second clamping plate of the fixture includes a second base plate, one end of which is connected to a second connecting plate and the other end of which is connected to a second upright plate.

[0009] Optionally, the first connecting plate and the first upright plate are both perpendicularly connected to the first base plate; the second base plate and the second upright plate are both perpendicularly connected to the second base plate.

[0010] Optionally, a slot is provided on the top end face of the first connecting plate, and the top of the second connecting plate has a protrusion that matches the slot of the first connecting plate.

Through a sealing clamp, the sealed end of the pneumatic rib can be quickly and safely engaged using clamping blocks, achieving rapid and safe installation. Simultaneously, the clamping blocks seal the pneumatic rib end, preventing damage caused by the rib end bursting open under high pressure.

[0020] Furthermore, the top outer edge of the first upright plate of this utility model has a first chamfer, and the top outer edge of the second upright plate has a second chamfer, which can prevent the air rib from being cut by sharp edges during use and causing danger.

[0083] The high-pressure air rib in this embodiment includes the following steps during installation:

[0084] First, by wrapping the air rib end 41 sequentially around the top, left side wall and bottom of the clamping block 3, and then wrapping it out from the bottom, the clamping block 3 is partially wrapped by the air rib end 41.

[0085] Then place the clamping block 3, which is wrapped around the air rib end 41, onto the first clamping plate 11 of the fixture, so that the end of the air rib end 41 extends outward from the top of the first vertical plate 1103.

[0086] Engage the protrusion 12020 of the second clamping plate 12 with the slot 11020 of the first clamping plate 11. Finally, connect the first clamping plate 11 and the second clamping plate 12 with fasteners 2, and then inflate the air rib 4.

[0087] By reserving a space between the slot 11020 and the protrusion 12020, and by splicing the first connecting plate 1102 and the second connecting plate 1202, a gap is left between the first upright plate 1103 and the second upright plate 1203. This allows the first upright plate 1103 and the second upright plate 1203 to be clamped by the air rib end 41 and inflated and raised. They can then move accordingly through the reserved space between the slot 11020 and the protrusion 12023. This prevents the air rib 42 from being worn through due to excessive clamping by the first upright plate 1103 and the second upright plate 1203 caused by deformation and expansion under high air pressure or displacement during use. Simultaneously, the first chamfer 11030 and the second chamfer 12030 prevent the air rib body 42 from being cut by the edge, thus avoiding potential danger.

[0088] Unless otherwise specified, the equipment components involved in the above embodiments are all conventional equipment components, and the structural settings, working methods or control methods involved are all conventional settings, working methods or control methods in the art unless otherwise specified.
