Detailed Description

In order to make the technical scheme of the present utility model better understood by those skilled in the art, the present utility model will be further described in detail with reference to the accompanying drawings and the detailed description.

As shown in fig. 1-2, an inflatable support column is used for supporting a supported object, and comprises a hollow inflatable stand column 2 with a closed inner cavity, wherein the inflatable stand column 2 comprises a stand column body 21, and an air inlet 25 is arranged on the stand column body 21. The inflatable upright post 2 is used as a hard rod such as a hard metal rod or a plastic rod to support a supported object, namely, is propped under the supported object, and has the advantages of light weight, foldable storage, small volume after folding and the like.

As shown in fig. 1 and 2, in order to provide the inflatable stand 2 with a good supporting capability, the stand body 21 includes a first PVC layer 2a, a cloth layer 2b and a second PVC layer 2c sequentially from inside to outside, and the cloth layer 2b is a non-elastic cloth layer or a mesh layer. The inflatable material of the inflatable stand column 2 adopts a structure that an inner PVC layer and an outer PVC layer are sandwiched by one cloth layer, is flexible and tough, and has the effect of limiting the expansion of the PVC layer because the cloth layer 2b is not elastic, and the inflatable stand column 2 can not be expanded again after being inflated continuously after being inflated fully, but can be harder. Therefore, the inflatable stand column 2 is hard after being inflated, is not easy to bend, can achieve the hardness and strength equivalent to those of a hard stand column (such as a metal rod), and can replace the metal rod.

In addition, since both sides of the cloth layer 2b are PVC layers, welding (heat press welding) is facilitated.

More specifically, the column body 21 is a cylindrical shape formed by rolling a whole sheet into a cylindrical shape, overlapping and welding the butt edges (as shown at B in fig. 2), wherein the column body is formed by adopting an overlapping connection mode, and is attractive after being formed and uniform in stress after being filled with air. End covers 22 for sealing are welded at the upper end and the lower end of the upright post body 21. Of course, the end cap 22 may be a hard end cap (e.g. a metal cap, a plastic cap) or a flexible cap (e.g. a plastic cap), which is convenient for molding, and may also increase the structural strength and service life of the inflatable stand 2.

In a more specific embodiment of the present utility model, as shown in fig. 1, the air valve 3 is disposed at the air inlet 25. For connection with an inflation tool to inflate and deflate.

In a more specific embodiment of the present utility model, as shown in fig. 3 and 4, the pressure release valve 9 is disposed on the inflatable stand 2. The air pressure in the inflatable stand column 2 can be ensured not to exceed the safety air pressure so as to ensure safety.

It is noted that the inflatable support column (i.e., inflatable stand 2) of the present utility model can be used in other fields, such as inflatable furniture, in addition to the tent described below.

As shown in fig. 5 to 13, a portable inflatable tent includes a tent cloth 1 and at least one inflatable stand 2 described above. The inflatable stand column 2 is propped under the awning cloth 1, the upper end of the inflatable stand column 2 is connected with the awning cloth 1, and a plurality of detachable pull ropes 4 are arranged on the periphery of the awning cloth 1. The inflatable upright post 2 is used as a supporting column and stands on the ground vertically, the upper end of the inflatable upright post 2 props up the awning cloth 1 from bottom to top, the periphery of the awning cloth 1 is tensioned by the pull rope 4, and the other end of the pull rope 4 is fixed on the ground or other heavy objects, so that a portable tent is formed, and the portable tent has a simple structure and is easy to assemble and disassemble.

Preferably, the awning cloth 1 is waterproof and sun-shading awning cloth.

Preferably, as shown in fig. 11, the air valve 3 and the pressure release valve 9 are arranged on the air charging upright 2. The air valve 3 is convenient to charge and discharge, and the pressure relief valve 9 can ensure that the air pressure in the charging upright post 2 does not exceed the safety air pressure so as to ensure safety.

Preferably, as shown in fig. 11 and 12, a plurality of hanging holes 12 are provided at intervals around the tarpaulin 1, and a hook 42 capable of being mutually hung with the corresponding hanging hole 12 is provided at one end of the pull rope 4. In this way, the pull cord 4 and the tarpaulin 1 are assembled and disassembled relatively quickly. Of course, it is preferable that the hanging hole 12 is provided with a metaler eye.

Preferably, as shown in fig. 11, the free ends of the pull ropes 4 are provided with ground nails 41. The ground nail 41 can be driven to the ground to fix the rope 4 to the ground, and the rope 4 can be directly tied to a weight such as a trunk or stone.

Of course, if there is only one inflatable column 2, the individual pull cords 4 are evenly arranged around the inflatable column 2; if the inflatable column 2 has two or more, the pull ropes 4 should be symmetrically arranged two by two, so that the sides of the tarpaulin 1 are uniformly tensioned.

The utility model uses at least one inflatable upright post 2 to prop up the tent cloth 1 (instead of using a metal rod to prop up the tent), and uses a plurality of pull ropes 4 to pull the periphery of the tent cloth 1, thereby rapidly forming a simple tent capable of shading sun and shielding rain. The utility model has simple structure and less parts. Moreover, the utility model is simple and convenient to install, store and fold and has high speed. Specifically, the inflatable upright post 2 is inflated and erected firstly, then the awning cloth 1 is covered, finally the stay rope 4 is connected to the awning cloth 1, and the other end of the stay rope 4 is fixed on the ground or the tree or the like. And on the contrary, the disassembly is simpler.

In the utility model, only the inflatable upright post 2 needs to be inflated, but not the whole tent, so the time required for inflation and exhaust is relatively short, and the time for taking up the tent is saved; but also is beneficial to greatly reducing the weight of the tent.

In the utility model, the inflatable upright post 2 can be folded after being deflated, and the tarpaulin 1 and the pull rope 4 are flexible and can also be folded. Therefore, the foldable tent can be folded and stored, has smaller volume after folding, small occupied space and small weight (compared with a fully inflatable tent, the volume and the weight are much smaller), and is suitable for being carried out.
