Description

The mobile film projection tent that steel arch is combined with gas arch

Technical field:

The utility model relates to the general tent of a kind of building, is that a kind of steel arch aerating arch is fluffy in conjunction with the mobile film projection of forming specifically.

Background technology:

There was a kind of convenient air filling type of the usefulness of showing a film, record fluffy greatly in the past, it is made up of gas arch, fluffy, hawser etc., by the whole fluffy body of the gentle arch brace of hawser, big fluffy being convenient for carrying of this kind, can flow combination become cinema, but it still has many weak points: use the fluffy body that has a power failure suddenly to land very soon midway, spectators have little time out fluffy promptly be crushed on fluffy in, cause confusion; The gas arch adopts the anti-gas-leak lining of individual layer, poor sealing performance, and easily gas leakage needs to be equipped with more powerful blower fan; Also can not suspension speaker because of weakness; It is smooth that the suspension of screen is also owed.

Summary of the invention:

It is fluffy that the utility model is intended to provide the projection that a kind of steel arch and gas arch combine, and big fluffyly can not land very soon is difficult for gas leakage during power failure after the inflation, only needs the blower fan of smaller power, and loudspeaker is easy to be suspended on rational height, and screen is hung smooth stable.The purpose of this utility model is finished like this: the mobile film projection tent that a kind of steel arch is combined with gas arch, and it includes blower fan, fluffy, gas arch, hawser; Be the steel arch of arc in the both ends or one end of fluffy body, big fluffy centre is gas arch, or a middle end that adds upper inlet is gas arch, and gas arch is by surface layer and application of anti-leakage layers is two-layer forms; Every secondary steel arch is pegged graft by the above arc joint of two joints and is formed, and encircles between the joint by the drag-line tractive.

The utility model anti-gas-leak performance is good, and the power of fan of use is little, and using electricity wisely can not landed after the power failure very soon, and loudspeaker and screen can be suspended on rational position.

Description of drawings:

Fig. 1 is a structural representation of the present utility model; Fig. 2 is a steel arch structure schematic diagram of the present utility model; Fig. 3 is gas arch cross section structure figure of the present utility model.

Among the figure: 1, steel arch; 2, gas arch; 3, arch joint; 4, plug tenon; 5, interface; 6, drag-line; 7, surface layer; 8, application of anti-leakage layers.

The specific embodiment;

Big two the fluffy sides of the utility model, namely its suspension screen end and entrance point support with steel arch 1, and every secondary steel arch 1 is assembled into by plural arch joint 2, on the arch joint 1 plug tenon 4 and interface 5 is arranged, and the docking by plug tenon 4 and interface 5 can form steel arch 1.With drag-line 6 tractives, make it to become firm integral body between joint arch 3 and the joint arch 3.Gas arch 2 its structures of the present utility model are surface layer 7 and application of anti-leakage layers 8 two-layer compositions, make gas arch form double-layered anti-leakage, and gas tightness is better.This projection is fluffy also can use steel arch 1 with hanging screen one side, and fluffy centre and arrival end all adopt gas arch 2.

Claims (2)

1, a kind of steel arch mobile film projection tent of being combined with gas arch, it includes blower fan, fluffy, gas arch, hawser; It is characterized in that: be the steel arch of arc in the both ends or one end of fluffy body, big fluffy centre is gas arch, or a middle end that adds upper inlet is gas arch, and gas arch is by surface layer and application of anti-leakage layers is two-layer forms.

2, a kind of steel arch according to claim 1 mobile film projection tent of being combined with gas arch is characterized in that: every secondary steel arch is pegged graft by the above arc joint of two joints and is formed, between the arch joint by the drag-line tractive.
