Technical Field

[0001] The utility model relates to a laminated airbag made of rubber and plastic film and a honeycomb curtain fabric with the laminated airbag. Background Art

[0002] The box body of the outdoor sightseeing elevator and the main body of the elevator shaft are made of glass. In summer, it is exposed to the sun. Installing an air conditioner can only cool down, and a beautiful and convenient sunshade curtain is needed. The honeycomb curtain (accordion curtain) is a very mature folding curtain similar to the shape of an accordion. Its curtain fabric can be contracted and stretched. After special processing, it has precise dimensions and elasticity. After stretching, the side presents a regular hexagonal hole shape arranged in a honeycomb pattern, and it gets its name from this. The honeycomb curtain is beautiful and has excellent sunshading and heat insulation effects. However, the current installation and use methods are either complex in structure and affect the appearance, or the upper installation method affects the line of sight. Moreover, it generally requires manual operation, which is inconvenient and not suitable for occasions such as sunshading of sightseeing elevators. Content of the Utility Model

[0003] The utility model provides a laminated airbag made of rubber and plastic film and a honeycomb curtain fabric with the laminated airbag. After the laminated airbag exhausts air, each layer can be closely attached. After inflating, it can expand and stretch, enabling the honeycomb curtain fabric with the airbag inside to be pneumatically retracted and extended without changing the appearance and performance. At the same time, it can be installed at a lower position.

[0004] To achieve the above invention purpose, the technical solution adopted by the utility model is as follows:

[0005] A laminated airbag made of rubber and plastic film, which includes an air pipe and an airbag string. The airbag string is formed by laminating and sequentially connecting a plurality of strip-shaped airbags, and the inner cavities are communicated. At least one air pipe is connected to the airbag.

[0006] Each airbag is a bladder formed by hermetically connecting the outer edges of the upper and lower rubber and plastic film pieces, with an inner cavity. Adjacent two airbags are attached and connected. The lower film piece of the upper airbag and the upper film piece of the lower airbag are aligned and partially attached to form a joint surface, and the joint surface is provided with ventilation holes.

[0007] The film piece is designed as a rectangular strip. To reduce wrinkles after inflation, the two ends of the film piece are designed as triangles. Each inner cavity of this rubber and plastic film laminated airbag does not require a separate dedicated air duct externally. The structure is simple. After exhausting air and compressing, the two rubber and plastic film pieces of each layer of the airbag can be closely attached, with a compact structure, suitable for narrow spaces.

[0008] A honeycomb curtain fabric with stacked airbags comprises the above-mentioned stacked airbags and the fabric. After the fabric is stretched, the side surface thereof presents a plurality of neatly arranged hexagonal honeycomb cells. The strip honeycomb cells are stacked and connected in sequence. Adjacent honeycomb cells are provided with cell joint surfaces. The fabric is elastic and can rebound and be compressed into a stacked sheet. The cell joint surfaces are provided with through holes for passing the stacked airbags. The stacked airbags are interspersed inside the fabric. A single airbag is provided in a single honeycomb cell.

[0009] The fabric described in this case is processed on the basis of the known honeycomb curtain fabric, and is different from the existing honeycomb curtain fabric in that each honeycomb nest hole joint surface is provided with a through hole. The existing honeycomb curtain fabric is in a compressed and stacked state after contraction in its natural state, and can be stretched and unfolded under the action of external force.

[0010] Furthermore, the stacked airbags are built into the cloth, and the airbag fitting surface is placed in the through hole, and the width of the fitting surface is smaller than the width of the through hole; the airbags are inscribed in the inner side of the honeycomb grid after being fully expanded; when the stacked airbags are connected to the air source through the trachea for inflating, the airbags expand, pushing the honeycomb grid of the cloth to stretch longitudinally, and when the air is deflated through the trachea, the honeycomb curtain cloth shrinks under the action of its own elastic force, driving the stacked airbags to shrink, and finally shrink together into a stacked sheet.

[0011] The beneficial effects of the utility model are as follows: the rubber-plastic film laminated airbag and the honeycomb curtain fabric with the airbag enable the honeycomb curtain to be pneumatically retracted and extended without changing the appearance and performance of the fabric, and the installation position is flexible and changeable, and can be installed in up, down, left, and right positions.

[0019] The technical solution of the utility model will be clearly and completely described below in conjunction with the drawings in the utility model examples. All other embodiments obtained by ordinary technicians in the field without making creative work based on the embodiments of the utility model are within the scope of protection of the utility model.

[0020] like Figure 1 The stacked airbag made of a rubber-plastic film shown in the figure comprises an air tube 1 and an airbag string. The airbag string is composed of a plurality of strip-shaped airbags 2 stacked and connected in sequence, and the inner cavities are connected. At least one air tube is connected to the airbags. In this case, an air tube is preferably provided on one side of the topmost or lowest airbag to connect to the air source.

[0021] Each airbag is a bag body with an inner cavity formed by sealingly connecting the outer edges 5 of the upper and lower rubber-plastic film sheets, and the two adjacent airbags are connected in affixed manner, and the lower film sheet of the upper airbag is aligned with the upper film sheet of the lower airbag and partially affixed to form a bonding surface 3, and the bonding surface is provided with a vent 4. The provision of the outer edge is conducive to the flat surface of the airbag after contraction being close to the plane where the outer edge is located, and is conducive to the contraction of the airbag string into a stacked state.

[0022] The film sheet is designed as a rectangular strip, and the two ends of the film sheet are designed to be triangular to reduce wrinkles after inflation. Each inner cavity of the rubber-plastic film laminated airbag does not need to be equipped with a separate dedicated airway, and the structure is simple. After exhaust and compression, the two rubber-plastic film sheets of each layer of the airbag can fit tightly, and the structure is compact, which is suitable for narrow spaces, such as Figure 2 As shown, after exhausting, the compressed stacked airbags can be tightly fitted together. The stacked airbags can be driven by a low-pressure air source and are safe to use.

[0023] exist Figure 3 In the figure, for the convenience of observation, the structure diagram of the honeycomb curtain fabric with stacked airbags is partially cut in many places, and the sixth and seventh airbags from the top are removed. Figure 3 A honeycomb curtain fabric with the above-mentioned stacked airbags is shown, which includes the above-mentioned stacked airbags and a fabric 6. After the fabric 6 is stretched, the side surface presents a plurality of neatly arranged hexagonal hole-shaped honeycomb grids. The strip honeycomb grids 8 are stacked and connected in sequence. Adjacent honeycomb grids are provided with a hole joint surface 9. The fabric 6 is elastic and can rebound and be compressed into a stacked sheet. The hole joint surface 9 is provided with a through hole 7 for passing through the stacked airbags. The stacked airbags are interspersed inside the fabric, and a single airbag is arranged in a single honeycomb grid.

[0024] The fabric 6 described in this case is processed on the basis of the known honeycomb curtain fabric, and is different from the existing honeycomb curtain fabric in that each honeycomb nest hole joint surface is provided with a through hole. The existing honeycomb curtain fabric is in a compressed and stacked state in its natural state, and can be stretched to expand under the action of external force.

[0025] The laminated airbag is built into the fabric 6. A single airbag is arranged in the honeycomb cell 8 of the fabric. The airbag fitting surface 3 is placed in the through hole 7, and the width of the fitting surface 3 is smaller than the width of the through hole 7. After the airbag 2 is fully inflated, it is inscribed in the inner side surface of the honeycomb cell 8, and the airbags on both sides of the through hole clamp the honeycomb hole joint surface in the middle. When the laminated airbag is inflated through the air pipe 1 connected to the air source, the airbag expands and pushes the honeycomb cell of the fabric to stretch longitudinally. When the air is released through the air pipe, the honeycomb curtain fabric contracts under the action of its own elasticity, driving the laminated airbag to contract, and finally the whole contracts into a laminated sheet together.

[0026] When the embodiment of the present utility model is applied to the installation of the honeycomb curtain, guiding holes can be opened on both end sides of the honeycomb curtain fabric, and a guide rod 10 is arranged in the guiding holes for guiding, as Figure 4 shown. The lower end of the honeycomb curtain fabric is fixed, and this embodiment diagram is the lower installation method.

[0027] Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model. The above description is only the preferred embodiment of the present utility model. It should be noted that for those of ordinary skill in the technical field, several improvements can be made without departing from the principle of the present utility model, and these improvements should also be regarded as the protection scope of the present utility model without creative efforts.
