Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
As shown in Figures 1 to 5, a kind of projection cloth storage device of the present invention includes shell and inner tube.
Shell is openable or closes.
As shown in figure 3, when the enclosure is opened, inner tube 1 is externally exposed in environment, as shown in Fig. 2, when shell is closed,
Inner tube 1 is built in shell, i.e., inner tube 1 is surrounded by shell.
Shell can surround a door, realize that it is opened or closed by door.
As shown in figures 1 and 3, shell include fixed frame and with respectively with fixed frame two sides rotation connection door shell
Body 1 and gate housing 2 22, gate housing 1 and gate housing 2 22 can be rotated relative to fixed frame, in the course of rotation
It realizes that shell is whole to open or close.
Further, it is contemplated that the projection cloth storage device is needed mobile or carried when closing, in order to prevent handling process
It is additionally provided with lock 15 in the situation that middle shell cannot lock, gate housing 1 and gate housing 2 22, realizes the locking of shell.
Further, for the ease of moving or carrying, handle 13 is respectively respectively equipped in gate housing 1 and gate housing 2 22.
In addition, the end of shell can also be equipped with handle 14.Handle 14 can further comprise handle front cover 5 and by handle screw 11 with
The handle rear cover 6 that handle front cover 5 connects.
As shown in Fig. 2, handle 14 can protrude from shell when original state, that is, shell surrounds inner tube 1.
In view of shell is placed on the stability on support face such as ground, the shape of shell can with but be not limited to institute in figure
The straight quadrangular shown.Meet the stability placed.
In view of inner tube 1 places stability inside the shell, inner tube 1 can be fixed on the fixed frame of shell.
Supporting element is additionally provided in inner tube 1, supporting element is flexibly connected with inner tube 1, can be rotated relative to inner tube 1, realizes support
The expansion of part is packed up.
As shown in Figure 1, the quantity of supporting element can be four shown in figure, superposed two supporting elements are defined as
Upper supporting piece 3, upper supporting piece 3 are gradually moved up by parallel with inner tube 2, and two supporting elements positioned at lower part are defined as lower support
Part 4.By taking lower support element 4 as an example, lower support element 4 is rotatablely connected by lower support tube mandrel 9 and inner tube 1, lower support element 4 gradually by
It is parallel with inner tube 2 to move down.
In order to which the movement to supporting element limits, the position corresponding with supporting element of inner tube 2 is respectively equipped with plastic parts, such as moulds
Glue part is enclosed in the top of upper supporting piece 3, and plastic parts includes preventing upper supporting piece excessively to moving up in the bottom of lower support element 4
Dynamic, lower support element excessively moves down, and plays position-limiting action.
Each upper supporting piece 3 and a lower support element 4 are one group, as shown in figure 3, above-mentioned two groups of supporting elements are located at inner tube
3 two sides, when upper supporting piece 3 and lower support element 4 are collapsed state, supporting element can be parallel with the axis direction of inner tube 2.Inside
Pipe 1 is externally exposed in the state of environment, and upper supporting piece 3 and lower support element 4 are deployable, the deployable angle to inner tube 1
It is 90 degree.
As shown in figure 5, the supporting element of four expansion is in the same plane, the projection cloth 7 for fixed expansion.
It is understood that upper supporting piece 3 and lower support element 4 are in and pack up when original state, that is, shell surrounds inner tube 1
State also equally is located in shell.From the point of view of space utilization, two sides of inner tube 1 are equipped with groove, such as Fig. 3 institute
Show, two lower support elements 4 are embedded in groove, and two upper supporting pieces 3 are bonded with lower support element 4.
Projection cloth 7 can be fixed on inner tube 1, and when original state, that is, shell surrounds inner tube 1, projection cloth is shown in Fig. 3 or Fig. 4
Reeling condition.As shown in Figure 1, the middle position of projection cloth 7 can be fixed in inner tube 1 by projection cloth fixed screw 8, projection
The both ends of cloth 7 are wound to centre.
In view of projection cloth 7 is horizontal spreading, then the height of the shell and inner tube 1 of storing projection cloth 7 can be expansion
Projection cloth 7 is in the greatest length of vertical direction, and such whole device can be smaller than the volume for the device that other vertical direction are unfolded, more
It is easy to carry.Such as when projection cloth 7 is rectangle, then the height of shell and inner tube 1 and projection cloth 7 are in the long side on vertical direction
Or short side is equal, the length of upper supporting piece 3 and lower support element 4 is respectively less than the height for being equal to inner tube at this time.
The above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations；Although with reference to the foregoing embodiments
Invention is explained in detail, those skilled in the art should understand that: it still can be to aforementioned each implementation
Technical solution documented by example is modified or equivalent replacement of some of the technical features；And these modification or
Replacement, the spirit and scope for technical solution of various embodiments of the present invention that it does not separate the essence of the corresponding technical solution.
