Wherein the projection body can generate a projection image. The projection curtain can present the projection image on the surface thereof so as to facilitate the user to watch the projection image. The projection body may select a projector.

Referring to fig. 1-4, an embodiment of the present utility model provides a projection curtain including a curtain body 400 and an inflatable curtain frame. Wherein, curtain body 400 is detachably connected with the inflatable curtain frame. When the projection curtain is required, the curtain body 400 is connected with the inflatable curtain frame so that the projection body projects an image onto the surface of the curtain body 400. When needing to accomodate projection curtain, dismantle curtain body 400 and aerify the curtain frame and accomodate alone to save curtain body 400, reduce curtain body 400 because the condition of the curtain body 400 damage that is difficult for preserving and leads to appears, thereby guarantee the projection effect.

With continued reference to fig. 1-4, an embodiment of the present utility model provides an inflatable curtain frame including a frame body 100 and a wrap 200.

Wherein, as shown in fig. 2, the frame body 100 has an inflatable cavity. The frame body 100 encloses an accommodating space in which the curtain body 400 is accommodated. When the curtain frame is required to be inflated, the inflation cavity can be filled with gas, so that the curtain frame is not easy to deform after being installed on the curtain body 400, and the tension of the curtain body 400 is ensured. In addition, the provision of the inflatable cavity may reduce the weight of the frame body 100. When the inflatable curtain frame needs to be stored, only the gas in the inflatable cavity needs to be discharged, so that the storage volume of the frame body 100 is reduced, and the frame body 100 is convenient to carry and store. The wrapping member 200 wraps at least a portion of the frame body 100. The wrap 200 is provided with a connector 210. The connector 210 is used for connecting with an object to be mounted. It should be noted that the above-mentioned objects to be mounted may include indoor and outdoor walls, and supports such as poles, trees, etc. provided outdoors are not limited to the above-mentioned examples, and the structure of the mountable inflatable curtain frame may be included in the scope of the above-mentioned objects to be mounted. The wrapping member 200 can protect the frame body 100, and reduce breakage of the frame body 100 due to collision of external force. Because the package 200 does not need to consider the air tightness, the package 200 can accommodate more errors and uneven local stress when being connected with the object to be installed, and the damage of the frame body 100 is reduced.

When the inflatable curtain frame is used, a user only needs to fill the inflatable cavity in the frame body 100 with gas, and then the wrapping piece 200 is wrapped on the surface of the frame body 100 to complete the lap joint of the inflatable curtain frame. The user may also fill the inflatable cavity in the frame body 100 with gas after wrapping the wrapping member 200 around the surface of the frame body 100. The operation needed by the formation of the inflatable curtain frame is convenient and quick, and the operation difficulty is lower. When the projection screen is stored, the gas in the inflation cavity of the frame body 100 may be discharged. The frame body 100 can be reduced to a smaller volume for easy carrying of the inflatable curtain frame.

Compared with a metal curtain frame, the inflatable curtain frame has the advantages that the cost is low, the manufacturing process is simpler, more users can use the curtain frame with lower monetary cost and time cost, and the use scene of projection equipment is widened. In addition, the inflatable curtain frame is light in weight, so that a user with small strength can move the inflatable curtain frame to a proper position at one time conveniently.

It should be noted that, the "wrapping member 200 wraps at least a portion of the frame body 100" includes both that the wrapping member 200 as shown in fig. 1 completely wraps the frame body 100 and that the wrapping member 200 wraps a portion of the frame body 100 as shown in fig. 4, and the remaining frame body 100 may be exposed to the outside.

The adoption of the scheme that the wrapping piece 200 is completely wrapped on the frame body 100 can protect the frame body 100 comprehensively and reduce the possibility of damage of the frame body 100. In addition, when the wrapping member 200 is completely wrapped on the frame body 100, the wrapping member 200 can be completely abutted against the outer surface of the frame body 100, so as to increase the abutting area with the frame body 100. When the wrapping member 200 receives a larger force locally, the force received by the frame body 100 abutting against the local is dispersed by the portions of other frame bodies 100, so that the occurrence of the situation that the frame body 100 is stressed excessively locally is effectively avoided.

As shown in fig. 2, 3, and 5, in some embodiments, the frame body 100 includes an air column 110. The middle part of the air column 110 is provided with an air charging cavity 111. The number of the air columns 110 may be four, and the four air columns 110 are connected end to end in sequence. The inflation chambers 111 of each of the columns 110 communicate to form the inflation cavity described above. Such an arrangement may reduce the complexity of the inflation operation and may also ensure that the gas content within each column 110 is substantially uniform, i.e., the degree of inflation of the columns 110 is substantially uniform. All the air columns 110 may be integrally formed, or may be connected by sealing, sewing, sealing, bonding, etc., so as to improve the strength and air tightness of the frame body 100.

Of all the air columns 110, any two oppositely disposed air columns 110 are parallel. Such an arrangement may be suitable for the projection body currently on the market, so that the frame body 100 is rectangular. At least one gas column 110 is provided with a gas valve 120, and gas entering and exiting the gas column 110 is achieved by the arrangement of the gas valve 120.

With continued reference to fig. 1-4, in some embodiments, the wrapping member 200 includes a wrapping portion 203 and a connecting portion 204, wherein the wrapping portion 203 wraps the frame body 100, that is, the wrapping portion 203 abuts against an outer surface of the frame body 100. The wrapping portion 203 is provided with a connector 210. The connection portion 204 may be detachably connected with the curtain body 400. In some embodiments, the connector 210 may be disposed on a side of the wrap 203 remote from the frame body 100. The wrapping portion 203 is fixedly connected with the connecting portion 204. It is understood that the connector 210 may be disposed on an outer surface of the wrapping portion 203, so as to facilitate connection of the connector 210 with an object to be installed.

Specifically, in some embodiments, the wrapping portion 203 is only abutted with the frame body 100, i.e., there is no connection therebetween. In other embodiments, the wrapping 203 has a connection relationship with the frame body 100, i.e., the wrapping 203 may be connected with an outer surface of the frame body 100. This reduces slippage of the wrapping 203 relative to the frame body 100 and also facilitates positioning of the wrapping 203 when the wrapping 203 is installed. In some embodiments, the connection portion 204 and the curtain body 400 may be at least one of a zipper connection, a velcro connection, a snap connection, a magnetic connection, a binding connection, and a hook-and-loop connection, but is not limited to the above detachable connection. The wrapping portion 203 and the connecting portion 204 may be fixedly connected by sewing, bonding, integrally forming, etc., but are not limited to the above-mentioned fixing connection method.

In some embodiments, one end of the connector 210 is connected to the wrapper 200. The other end of the connector 210 is free, i.e. it need not be connected to other structures. The connection member 210 is provided with a connection through hole. When the connector 210 is connected with the object to be mounted, the connector 210 can be connected with the object to be mounted by passing through the connecting through hole through a hook, a hanging rope and the like. Compared with the embodiment that one end of the connecting piece 210 is connected with the wrapping piece 200 and the other end of the connecting piece 210 is connected with the object to be installed, the connecting piece 210 is more universal, namely the connecting piece 210 is not limited to the length of the connecting piece 210 and the position of the connecting piece 210, and the installation of the inflatable curtain frame in different scenes can be completed by adjusting the position of the hanging hook or the length and the angle of the hanging rope, so that the applicability is stronger.

It will be appreciated that in some embodiments, the connector 210 may be a flexible structure, such as a cloth material, a rubber material, or the like. The connector 210 of flexible structure can be easily stored, and is not easily scratched to the package 200 or the frame body 100 during storage. In other embodiments, the connecting member 210 may be a rigid structure, such as a metal material, a hard plastic material, or the like. When the connecting piece 210 with the rigid structure receives external force, the connecting through hole is not easy to deform, and the service life is longer. In addition, in some other embodiments, the connector 210 may be a structure of a rigid material and a flexible material. Such an arrangement allows for the connection through-hole to be less prone to deformation and the connector 210 to scratch the package 200 or the frame body 100.

As shown in fig. 1-4, in some embodiments, the number of connectors 210 is multiple. The plurality of connection members 210 are disposed at intervals along the circumferential direction of the frame body 100. The compatibility of the inflatable curtain frame can be improved through the arrangement mode, namely, the connecting pieces 210 at different positions can be connected according to different conditions, so that the inflatable curtain frame is connected with the installed object. In addition, the plurality of connecting members 210 can facilitate dispersing local stress of the wrapping member 200, and reduce damage to the wrapping member 200 due to excessive local stress.

It will be appreciated that in other embodiments, the wrap 200 may be provided with only the wrap 203. The wrapping 203 may be provided with a clearance hole (not shown). At least a portion of the curtain body 400 may be detachably coupled with the frame body 100 through the clearance hole.

In some embodiments, the wrap 200 provides a containment structure. The receiving structure may receive the weight 300. The weight 300 may be a sand bag, a lead bar, a metal bar, or the like with a large mass, but is not limited to the above weight. By mounting the weight 300 within the receiving structure of the wrap 200, the weight of the inflatable curtain frame may be increased. Especially in the open air, when the curtain body 400 is blown by the wind, the shaking degree of the curtain body can be reduced when the weight of the inflatable curtain frame is large, and even the curtain body 400 does not move. It will be appreciated that when the inflatable curtain frame is received, the weight 300 is removed from the receiving structure without increasing the weight of the inflatable curtain frame. In some embodiments, the containment structure may be disposed on an outer surface of the wrapper 203. Such a configuration may prevent the weight 300 from directly acting on the curtain body 400 when the connecting portion 204 is connected to the curtain body 400, so that a portion of the curtain body 400 is not subject to a large pulling force.

Referring to fig. 3, in some embodiments, the receiving structure may be a pocket structure, i.e., at least one side thereof is not connected to the packing member 200 to form an opening to facilitate the insertion or removal of the weight 300. For example, in some embodiments, the containment structure may be sheet-like. The receiving structure is connected to the packing member 200 along both opposite sides in the gravitational direction, and is not connected to the packing member 200 along at least one of the opposite sides perpendicular to the gravitational direction to form an opening so that the weight 300 is placed in the receiving structure. In other embodiments, the receiving structure is connected to the wrap 200 along one side of the bottom in the direction of gravity and the top forms an opening, with the receiving structure being connected to the wrap 200 along opposite sides perpendicular to the direction of gravity.

In other embodiments, the receiving structure may be a strap structure, i.e., the weight 300 may be bound to the wrap 200 by the receiving structure. In some other embodiments, the receiving structure may also be hooked or through-hole to facilitate removable connection with the weight 300.

As shown in fig. 1, in some embodiments, the number of the accommodating structures may be one or more, at least one accommodating structure is located at a middle lower portion of the packing member 200 in the gravity direction, so that the counterweight 300 is installed in the accommodating structure, and the inflatable curtain frame is not easy to shake. That is, the receiving structure may be provided at the packing 200 packed at the air column 110 in the gravity direction. Such an arrangement can better satisfy the counterweight effect.

In addition, as in the embodiment shown in fig. 1, the receiving structure may be symmetrically disposed along the center line (perpendicular to the gravitational direction) of the frame body 100. The above arrangement can facilitate the installation fault tolerance without considering the relative positions of the two air columns 110 along the direction of gravity when installing the inflatable curtain frame. That is, if one of the two air columns 110 is provided at a lower position, the weight 300 may be mounted only in the receiving structure located at the lower position, or the weight 300 may be placed in the receiving structure at both air columns 110. If the other of the two air columns 110 is disposed at the lower position, the weight 300 may be mounted in the accommodating structure disposed at the lower position, or the accommodating structures at the two air columns 110 may be used to place the weight 300, so that the inflatable curtain frame does not need to be adjusted, which is convenient.

It should be noted that at least one weight 300 may be accommodated in one accommodating structure. When a plurality of weight pieces 300 can be accommodated in the accommodating structure, a user can flexibly increase and decrease the number of the weight pieces 300 according to the use scene, and the user does not need to carry more weight pieces 300 in windless or indoor scenes, so that the convenience is improved.

As shown in fig. 1-3, in some embodiments, the connection 204 may be disposed outside of the receiving structure, i.e., the connection 204 is connected to the wrap 200 through the receiving structure. The arrangement can save space, and the connection part 204 and the accommodating structure can face to a specific direction, i.e. the connection part 204 or the accommodating structure is not needed to be kept away. In other embodiments, as shown in fig. 4, the connection portion 204 and the receiving structure may be disposed at intervals, i.e., without a connection therebetween. Such an approach may facilitate the production of the package 200 while providing the receiving structure and the connection 204 to the package 200, saving time and costs.

As shown in fig. 6, in some embodiments, one side of the wrap 200 is provided with a first attachment structure and the other side of the wrap 200 is provided with a second attachment structure. When the wrapping member 200 wraps at least a portion of the frame body 100, the first connecting structure and the second connecting structure cooperate to form an annular cavity for accommodating at least a portion of the frame body 100.

In some embodiments, the first connection structure and the second connection structure are fixedly disposed, such as by stitching, adhesive, or the like. Such an arrangement may facilitate the finding that the wrapping member 200 is not easily separated from the frame body 100 when the wrapping member 200 wraps the frame body 100, thereby reducing the loss of the wrapping member 200.

In some embodiments, the first connection structure and the second connection structure are detachably disposed, so that the package 200 is separated from the frame body 100 more conveniently, so as to replace or repair the package 200 in time.

For example, in some embodiments, the first connection structure and the second connection structure may constitute a zipper structure. In some embodiments, the first connection structure and the second connection structure may form a hook-and-loop structure, i.e., the first connection structure is a portion having a hook-like structure, and the second connection structure is a portion having a loop-like structure. In some embodiments, the first connection structure and the second connection structure may form a snap structure, such as a snap structure. In some embodiments, the first connection structure and the second connection structure may form a button structure, for example, the first connection structure is a protruding structure, and the second connection structure is a through hole structure, and the two structures cooperate to form the button structure. In some embodiments, the first connection structure and the second connection structure may be magnetic attraction structures, that is, they are opposite magnetic poles. It is understood that the first connection structure and the second connection structure may adopt at least one connection mode as described above, that is, may be a combination of multiple connection modes, and may be selected according to practical situations. It should be noted that the first connection structure and the second connection structure are not limited to the above-listed structures.

Referring back to fig. 3, in some embodiments, the wrapper 200 includes a body layer 201 and a decorative layer 202. The body layer 201 abuts against the frame body 100. The decorative layer 202 is disposed on the outer surface of the body layer 201. The decorative layer 202 may be patterned by printing or the like to facilitate increasing the ornamental value of the package 200.

As shown in fig. 1 and 4, the number of the wrapping members 200 may be one or more.

In some embodiments, the number of wrappers 200 is one, i.e., one wrapper 200 may wrap at least a portion of the frame body 100, thereby achieving protection of the frame body 100. Such an arrangement may provide for a partial separation of the package 200 that is not likely to occur when the package 200 is received, as well as a loss of some of the components due to an excessive number of components. Specifically, as shown in fig. 1, the number of the packing members 200 is one. The wrapping 200 may be wrapped around at least a portion of the four columns 110 simultaneously.

It can be appreciated that, in the above-mentioned technical solution that the wrapping member 200 can be wrapped at least partially on the four air columns 110 at the same time, the technical solution that the wrapping member 200 is wrapped at the whole outer surfaces of all the air columns 110 at the same time, the technical solution that the wrapping member 200 can be wrapped at the outer surfaces of the local parts of all the air columns 110 at the same time, and the technical solution that the wrapping member 200 can be wrapped at the outer surfaces of the local parts of the air columns 110 at the same time and the whole outer surfaces of the rest air columns 110 at the same time are included.

In some embodiments, the number of the wrapping members 200 may be plural, the plurality of wrapping members 200 may be connected to each other, and the connection manner may be a detachable connection manner or a non-detachable connection manner, such as a connection manner of a hook and loop fastener, a zipper connection, a snap connection, a fitting, an integrally formed arrangement, etc. As shown in fig. 4, the number of the wrapping members 200 is two or more, and each wrapping member 200 wraps at least part of a different air column 110. Such an arrangement allows for more flexibility in installing and replacing the package 200.

The inflatable curtain frame is small in mass, convenient to carry, low in cost and simple to operate. The shaping of inflation curtain frame can be accomplished only to the gas filling in the cavity that aerifies to and only need the gassing can accomplish the accomodating of inflation curtain frame. The package 200 may protect the frame body 100, and the package 200 may facilitate the installation of the connector 210 and the receiving structure. The wrapping piece 200 is detachably connected with the curtain body 400 through the connecting portion 204, so that the curtain body 400 can be independently stored, and the connecting mode is simpler.
