Specific embodiment

The utility model is furtherd elucidate with reference to the accompanying drawing.

As shown in Figure 1, back box protective device of blowing, including rectangle fence 1, the depth of rectangle fence 1 are greater than bottom a kind ofly The depth of box；Four angles of rectangle fence 1 are equipped with fixed block 2, and air bag 3 is equipped in rectangle fence 1, and air bag 3 and fixed block 2 connect It connects, the depth of air bag 3 is equal with fixed block 2, and length and width and 1 length of rectangle fence are equal with width, and air bag 3, which is equipped with, to be filled Stomata；The fixed block 2 is equipped with stretching structure 4.

The rectangle fence 1 is structure as a whole with fixed block 2, can be according to the size design of fresh air back box.In use, directly Rectangle fence 1 is placed in fresh air back box, is then inflated into air bag 3, air bag 3 can integrally cover back box after being full of gas Then lid carries out decoration construction, while the quadrangle of rectangle fence 1 has fixed block 2, and fixed block 2 is equipped with stretching structure 4, mentions Pull-up structure 4 includes but is not limited to lift bracelet, T-shaped structure, lifting hook, magnetic block etc..The stretching structure 4 of protrusion can remind dress It repairs worker to avoid burying by back box, simultaneously because the protection of air bag 3, cement in work progress, dust etc. will not enter Into back box, there is good protective effect to back box.In addition, when later period finishing patch floor or ceramic tile, it can be according to lifting Size is reserved at the position of structure 4, is thus not in that size is opened and opens small problem greatly.And construction in later period terminates, surface wind When mouth debugging, directly entire protective device is taken out using stretching structure 4, it is time saving and energy saving.

The air bag 3 is the cuboid air bag equal with 1 volume of rectangle fence, and four seamed edges are fixed or removably pacified On four fixed blocks 2.Dismountable mounting means is conveniently replaceable, repairs.

For the ease of storage, as shown in Fig. 2, the fixed block 2 is round fixed block, four sides of rectangle fence 1 are equal It is hinged on the fixed block 2 on four angles, after the completion of constructing as a result, the fence shape of rectangle can be folded into flat pattern, Convenient for storage.

In order to which four fixed blocks 2 are firmly fixed in back box, each 2 bottom of fixed block is equipped with several nails Son, nail length 3-5mm need to only be knocked in nail with hammer in use, firmness is of less demanding because being to be fixed temporarily Ground, without punching.

In order to meet different back box sizes, the one group of symmetric side or two groups of symmetric sides of the rectangle fence 1 For retractable structure, the size of the air bag 3 is equal to maximum sized size after rectangle fence 1 extends.1 side of rectangle fence can Flexible structure includes but is not limited to following several:

The first, as shown in figure 3, the retractable structure of 1 side of rectangle fence is the flexible network 5 of existing diamond shape, This network stretching structure is widely used the every field in life, such as scalable burglary-resisting window, flexible grid wood hedge Basketry, retractable door etc., flexible principle are no longer repeated here.In use, existing be fixed on the one of back box for the fixed block 2 at an angle Then angle stretches the side of rectangle fence 1 to other three of back box simultaneously in width direction or length direction or both direction Then other fixed blocks 2 are successively fixed at angle, then inflate to air bag 3, and air bag 3 can integrally cover back box after being full of gas, so After carry out decoration construction, subsequent process with it is above-mentioned equal, no longer repeat herein.

Second, as shown in Figures 4 and 5, the retractable structure of 1 side of rectangle fence is pull plate component 6, two adjacent Fixed block 2 is equipped with fixed pull plate 61, and fixed pull plate 61 is equipped with upper and lower two tracks 7, two fixed pull plates 61 it Between be equipped with mobile pull plate 62, mobile pull plate 62 is equipped with upper and lower two protrusion bars 8, and protrusion bar 8 is installed on fixed pull plate In 61 track 7, mobile pull plate 62 can be moved along fixed pull plate 61.In order to be fixed after being stretched to mobile pull plate 62 Limit, is equipped with several card slots 9 on the fixed pull plate 61, and mobile pull plate 62 is equipped with corresponding with 9 size of card slot Fixture block 10 is protruded, protrusion height 3-5mm can easily pull mobile pull plate 62 very much under external force, and fixture block 10 holds It easily slides into card slot 9 and thus mobile pull plate 62 is fixed.

The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art For art personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these improve and Retouching also should be regarded as the protection scope of the utility model.
