AI Technical Summary
Existing inflatable tents have problems with their inflatable column supports, such as complicated welding processes, long production cycles, high manufacturing costs, low structural strength, and low air pressure resistance. Furthermore, temperature changes can cause unstable air pressure.
The tent frame is made of composite high-pressure belts and plastic connectors. The composite high-pressure belts are made of warp and weft woven tubing and inner rubber lining membranes, which are heat-sealed or glued together. The plastic connectors are assembled by sealing the connection of each component, avoiding welding.
It has achieved an inflatable column support that is simple to manufacture, low in cost, has high inflation pressure, small column diameter, and high rigidity, and has good stability to adapt to temperature changes.

Abstract
Description
Technical Field
[0001] This invention relates to the field of tents, specifically a composite high-pressure belt tent frame. Background Technology
[0002] Tents are widely used for camping and disaster relief. Inflatable tents are currently favored by consumers for their ease of setup and storage, and the inflatable column frame, as a key component, is particularly important. Most inflatable tent column frames are currently made of the same material (such as PVC or TPU tubing) welded or glued together using clamps. For inflatable column frames with many and complex joints, the welding process is cumbersome, the production cycle is long, and the manufacturing cost is high. Furthermore, single-material inflatable column frames have low structural strength and low pressure resistance, requiring sewn or glued fabric covers for use. Even then, the pressure resistance is still relatively low. Currently, the permissible inflation pressure for inflatable tent column frames is generally 5-7 psi, with a maximum of 10 psi. Most inflatable column frames are equipped with pressure relief valves; if the temperature rises after inflation, the air pressure increases and automatically releases air. If the temperature drops, the gas pressure inside the column is insufficient, resulting in weak column rigidity. To allow such low-pressure inflatable column frames to expand and support the tent fabric while providing some wind resistance, thicker inflatable columns are needed.
[0003] This invention was made based on this situation. Summary of the Invention
[0004] This invention addresses the shortcomings of existing technologies by providing a composite high-pressure belt tent frame made of a composite high-pressure belt sealed with plastic connectors. It has the advantages of simple manufacturing, convenient implementation, low cost, strong inflation pressure, small inflation column diameter, and high rigidity.
[0005] The objective of this invention is achieved as follows: This technical solution includes a composite high-pressure belt and plastic connectors. The composite high-pressure belt is a flexible, circular belt integrally formed by heat-sealing or adhesive bonding of a warp and weft braided tubing and an inner lining membrane. The warp and weft braided tubing is preferably made of polyester or nylon fibers, but other high-strength fiber braided tubing can also be used. The inner lining membrane is preferably a soft gel membrane such as polyurethane or polyethylene. The inner lining membrane is inserted into the warp and weft braided tubing and heat-sealed or adhesive bonded to form an integral composite high-pressure belt for use as a tent inflatable column support. The heat-sealing or adhesive bonding process is a known technology. The plastic connector includes a plastic sealing connector and a plastic N-way (two-way, three-way, four-way, etc. can be selected as needed). The plastic sealing connector is a round tubular plastic part with an internal thread at its front end. An inner ring is provided at the end of the internal thread, and a circular soft rubber sealing gasket is installed at the inner ring. A soft rubber sealing ring (or sealant) is fitted on the outside of the plastic sealing connector. The two ends of the composite high-pressure belt are respectively fitted onto the plastic sealing connector and tightened with a locking throat. The plastic N-way interface end is provided with an external thread. The plastic sealing connector is installed at the plastic N-way interface. The plastic sealing connector that does not need to be connected to the plastic N-way is sealed with a plastic screw plug (if the plastic N-way interface does not have an external thread, it can be directly sealed to the composite high-pressure belt; the composite high-pressure belt that does not need to be connected to the N-way end can be sealed with a plastic plug). A hole is drilled at one of the composite high-pressure belts that does not need to be connected to the plastic N-way to install an air nozzle. In practical implementation, for example, to make an inflatable column support for an arched tent, it can be made into an "H" shaped support. Four equal-length composite high-pressure belts are cut as support belts, and one composite high-pressure belt of appropriate length is cut as a crossbeam belt (several crossbeam belts can be set as needed). Plastic sealing connectors are installed at both ends of each composite high-pressure belt. Preferably, there are two plastic tees, each connecting two composite high-pressure belts used as support belts. The plastic sealing connectors at both ends of the composite high-pressure belt used as a crossbeam belt are respectively connected to the two plastic tees. A hole is drilled at the lower end of one of the composite high-pressure belts used as a support belt to install an air nozzle. After the inflatable column support is installed inside the arched tent and inflated, the composite high-pressure belts are constrained by the shape of the tent and bend and open to support the tent.
[0006] By adopting the above technical solution, the present invention has the following advantages compared with the prior art: This invention provides a composite high-pressure belt tent frame, manufactured using composite high-pressure belts and plastic connectors. The composite high-pressure belt is a flexible, circular tubular belt formed by heat-sealing or adhesive bonding of a woven warp and weft threaded tube and an inner rubber lining. This composite high-pressure belt, used in the manufacture of tent inflatable column frames, exhibits strong high-pressure resistance. The plastic connectors link the composite high-pressure belts, eliminating the need for welding and simplifying assembly. The tent inflatable column frame implemented using this technical solution has the advantages of high inflation pressure, high rigidity, small air column diameter, low cost, simple and convenient manufacturing, and ease of assembly and maintenance.

The composite high-pressure belt 1 is a flexible circular tube belt integrally formed by heat-sealing or adhesive bonding of a warp and weft braided tube belt 11 and an inner rubber lining membrane 12.

The heat-sealing or adhesive bonding process is a known technology. The plastic connector includes a plastic sealing connector 2 and a plastic n-port 3 (preferably a two-way, three-way, or four-way connector, depending on the needs). The plastic sealing connector 2 is a cylindrical plastic part with an internal thread 21 at its front end. An inner ring platform 22 is provided at the end of the internal thread 21, and a circular soft rubber sealing gasket (not shown in the figure) is installed at the inner ring platform 22. A soft rubber sealing ring (not shown in the figure, but sealant can also be used) is fitted on the outside of the plastic sealing connector 2.

The interface end of the plastic n-port 3 is provided with an external thread. The plastic sealing connector 2 is installed at the interface of the plastic n-port 3. The plastic sealing connector 2 that does not need to be connected to the plastic n-port 3 is sealed with a plastic screw plug (if the interface of the plastic n-port 3 does not have an external thread, it can be directly sealed to the composite high-pressure belt. The composite high-pressure belt does not need to be connected to the n-port 3 end and can be sealed with a plastic plug). One of the composite high-pressure belts 1 does not need to be connected to the plastic n-port 3 end of the drilling device nozzle 4. In practical implementation, for example, to make an inflatable column support for an arched tent, it can be made into an "H" shaped inflatable column support. Four composite high-pressure belts 1 of equal length are cut as support belts, and one composite high-pressure belt 1 of appropriate length is cut as a crossbeam belt (several crossbeam belts can be set as needed).
