Abstract

A large-scale inflatable tent comprises a tent main body, inflatable equipment and a door, wherein the upper part of the tent main body takes the shape of a spherical cap while the lower part of the tent main body adopts a hollow circular platform-shaped base, a skirt edge is formed on the inner side of the circular platform-shaped base, and fixing holes are pre-formed on the skirt edge; fixing holes are also formed along the axis direction of ballasts, matched with that on the skirt edge in position, and fixedly connected with one another; and the length of the ballasts is in fit with the peripheral length of the circular platform-shaped base. In the utility model, a pressing sand system taking the ballasts as the main body is adopted to anchor the entire tent, thereby resulting in simple structure and convenient installation; the dead weight of the ballasts is heavy, and the friction resistance between the ballasts and the ground is large, thereby fixedly positioning the tent main body; the entire structure adopts none of air bags, air columns or shaped frame structures for the fixing and supporting, thereby keeping the inner and the outer surfaces flat and smooth; and the spherical cap can adopt single fabric, thereby guaranteeing the projection from the interior of the spherical cap to the outer surface of the spherical cap. Therefore, both the inner and outer surfaces of the entire spherical cap can be effectively utilized, so that the large-scale inflatable tent is particularly suitable for serving as an internal/external video projection screen.

Description

A kind of large-scale air dome

Technical field

The utility model belongs to the tent manufacture technology field, relates to a kind of large-scale tent, relate in particular to a kind of in no support, outer do not have auxiliary fixing, the tent top of long rope be smooth ball planar, be applicable to and make the 360 large-scale air domes of spending the inside and outside projection screens.

Background technology

Present commercially available tent, no matter rectangle house shape or circular tent like, being mostly has a stent support by interior, has long rope to connect tent top from different directions outward and does auxiliary fixing with pile.If a long rope is arranged or place the connection securing member at long rope two ends to break down, the then adjacent long rope and the connection securing member at two ends thereof must bear bigger tensile force, even produce chain reaction, cause tent to collapse and have potential safety hazard.

Gasbag-type air filling type tent utilizes inflation to form gas column, the body that puts up a tent.Large-scale tent is because volume is bigger, is designed to foldingly mostly, uses in the tent many air bags gas column to support, or is many air flues segmentation assembly type.And large-scale air filling type tent is bigger owing to body, and most tents also use long rope and timber fixing means to come the anchoring tent outward.

In the last few years, along with the needs of amusement, public activity, propaganda and science popularization, more and more as the activity space on spacious ground with the large-scale activity tent.But when tent is used as projection screen, because the defective (as the use of air bag gas column and tangible supporter) on the overall structure causes tent body inner surface or external surface out-of-flatness; Use air bag gas column structure, it is double-decker that the tent main body must have part, this can be to causing adverse effect from the inner outwards surface projection of tent, more than these factors when causing existing tent to do projection to use, mostly can only use as the inner projection screen, perhaps, can not use as the inside and outside projection of 360 degree as single outer projection's screen.

Summary of the invention

The purpose of this utility model be to provide a kind of in no support, outer do not have auxiliary fixing, the tent top of long rope be smooth ball planar, be applicable to and make the 360 large-scale air domes of spending the inside and outside projection screens.

For achieving the above object, the technical scheme that adopts is: a kind of large-scale air dome, comprise tent main body and charger and door, it is characterized in that: described tent main body top is the spherical crown shape, the bottom is the round table-like base of hollow, described round table-like base inboard is equipped with the shirt rim, fixing hole is preset in described shirt rim, preset fixing hole along described ballast axis direction, fixing hole position coupling is preset in position and shirt rim, and interconnecting fixingly, the length of described ballast and the peripheral length of described round table-like base match.

The sandbag that the built-in front and back up and down of described ballast closely link to each other.

The beneficial effects of the utility model are:

1. adopt the whole tent of the husky system's anchoring of pressure based on ballast, simple in structure, install convenient since ballast from heavy, the frictional resistance between ballast and ground is big, be enough to make tent main body positioning and fixing, can wind-engaging and produce moving of horizontal or vertical direction;

2. do not use any air bag, gas column or tangible supporting structure to carry out fixed support in the total, can keep the spherical crown surfaces externally and internally smooth smooth; Spherical crown can use woven, can not influence from the projection of spherical crown inside to the spherical crown external surface, and therefore whole spherical crown surfaces externally and internally all can effectively utilize, and is particularly suitable for using as inside and outside video-projection screen;

3. tent main body top spherical crown shape structure and ballast press husky system to make the tent tightness good, use blast fan constantly air directly to be blown in the tent main body, can keep the tent main body full.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the utility model overall structure schematic diagram;

Fig. 2 is a side shirt edge structural representation in the round table-like base;

Fig. 3 is the plane outspread drawing of ballast.

Among the figure, 1-tent main body; 2-spherical crown shape; The round table-like base of 3-; The 4-shirt rim; The 5-sandbag; The 6-ballast; The 7-door; 8,8 '-fixing hole.

The specific embodiment

By Fig. 1 the utility model overall structure schematic diagram as seen, a kind of large-scale air dome, comprise tent main body 1, door 7 and charger, it is characterized in that: described tent main body 1 top is spherical crown shape 2, the bottom is the round table-like base 3 of hollow, described round table-like base 3 inboards are equipped with shirt rim 4, described shirt rim preset fixing hole 8 ', preset fixing hole 8 along described ballast 6 axis directions, fixing hole 8 ' be complementary is preset in position and shirt rim, and interconnecting fixingly, the peripheral length of the length of ballast 6 and described round table-like base 3 matches.

The sandbag 5 that described ballast 6 built-in front and back up and down closely link to each other.

When mounted, the cloth circularly that one deck is made by canvas cloth can be laid on the ground, to increase the water resistance and the tightness of tent earlier earlier.The strip PVC fabric that ballast 6 can adopt both sides as shown in Figure 3 to have and preset fixing hole 8 is made, and strip PVC fabric is laid along perimeter edge in the cloth circularly.The sandbag 5 that design is needed weight is stacked and placed on the centre of strip PVC fabric along the axis direction compact reactor, along axis direction strip PVC fabric is upwards turned up to make both sides preset fixing hole 8 alignment to be close to, and is connected with nylon rope stitching or fastening or tether.Two minor faces of strip PVC fabric can be directly with the rope tying.As seen from Figure 2, round table-like base 3 inboards of tent main body 1 are equipped with shirt rim 4, shirt rim 4 preset fixing hole 8 ', its position with the fixing hole 8 that presets along ballast 6 axis directions is complementary, by fixedlyed connected in shirt rim 4 fixing hole 8 and methods such as 8 ' stitching or fastening or tether with ballast 6.For strengthening the anti-extreme wind ability of tent, can preset one or more static line in described ballast 6 bottoms, static line is lain on the spud pile of ground anti-tent occurred level displacement.

During use, air is constantly blown into the inside of tent main body, make tent body interior air pressure be about 1.5 times of external pressure, can keep its profile with hair-dryer.
