Technical field

The utility model relates to paper-extracting box, relates in particular to a kind of paper-extracting box of variable volumeization.

Background technology

Though existing paper-extracting box is various, yet its volume generally is immutable.When the volume of paper-extracting box hour, can not deposit more paper extraction; And when the paper-extracting box volume is big, though can deposit more paper extraction, be not easy to depositing and carrying of paper-extracting box itself, cause the inconvenience of use.

The utility model content

To the problems referred to above, be necessary to provide a kind of paper-extracting box of variable volume.

A kind of paper-extracting box comprises loam cake, lower cover and a plurality of sidewall, covers on said to offer the through hole that supplies paper extraction to pass; Said loam cake, lower cover and sidewall surround the host cavity in order to ccontaining paper extraction; Each said sidewall is a shutter, at least one stay cord that it comprises a plurality of blades and is fixed in each blade, and said stay cord has a redundant length between per two adjacent said blades; Said stay cord one end is fixed in said lower cover, and the other end is fixed in said loam cake movably.

Preferably, the redundant length of said stay cord between per two adjacent said blades equates that with the width of said blade perhaps said redundant length is greater than the width of said blade.

Preferably, said stay cord is fixed in the corresponding end of each blade successively.

Preferably, said stay cord is fixed in the two ends of each said blade, and makes between per two adjacent said blades and join end to end.

Preferably, the quantity of the said stay cord that each said sidewall comprises is two, and two said stay cords are arranged at the two ends of sidewall respectively.

Preferably, said paper-extracting box also comprises many expansion links, and many said expansion links are supported between said loam cake and the lower cover at interval, and the height of said expansion link is along with the elongation of said sidewall or compression and corresponding elongation or compression.

Preferably, the quantity of said expansion link is identical with the quantity of sidewall.

Described paper-extracting box makes the volume of paper-extracting box can do respective change as required through Height Adjustable sidewall is set, and can take under the situation of paper extraction the convenience of depositing and carrying that improves paper-extracting box not influencing paper-extracting box.

The following specific embodiment will combine above-mentioned accompanying drawing to further specify the utility model.

The specific embodiment

See also Fig. 1, the described paper-extracting box of the utility model is used to deposit paper extraction.The paper-extracting box 10 of the utility model preferred embodiments is by loam cake 11, lower cover 13 and link to each other successively and surround around a plurality of sidewalls 15 of loam cake 11 and lower cover 13 peripheries.Said loam cake 11, lower cover 13 and sidewall 15 surround the host cavity 16 in order to ccontaining paper extraction.Offer the through hole 111 that supplies paper extraction to pass on the loam cake 11.The length of sidewall 15 between loam cake 11 and lower cover 13 can correspondingly be regulated along with the height change of paper extraction, promptly elongates or shortens.So, the distance between loam cake 11 and the lower cover 13 can correspondingly elongate or shorten, thus make said host cavity 16 the corresponding increase of volume or reduce to adapt to the paper extraction of different size.

In this preferred embodiments, said loam cake 11 and lower cover 13 rectangular lid shapes, the quantity of sidewall 15 is four, each sidewall 15 be installed in loam cake 11 wherein on one side with corresponding one side of lower cover 13 between.

Please consult Fig. 2 to Fig. 4 in the lump, said sidewall 15 is for shutter designs, and it blade 151 that comprises a plurality of intervals reaches at least one stay cord 153 that is fixed in each blade 151 successively.Stay cord 153 can be fixed in each blade 151 corresponding end (like Fig. 2, shown in 3) successively, also can be fixed in the two ends of each blade 151 and make join end to end between per two adjacent blades 151 (as shown in Figure 5) successively.Stay cord 153 has certain redundant length between per two adjacent blades 151, and equates with the width of blade 151 or said redundant length during greater than the width of blade 151 that the flexible effect of sidewall 15 is preferable when said redundant length.Each stay cord 153 1 end is fixed in lower cover 13, and the other end is fixed in a plurality of blades 151 backs and is passed by loam cake 11.Stay cord 153 is arranged in loam cake 11 slidably, loam cake 11 and sidewall 15 is separated so that said paper extraction is packed in the host cavity 16.

Because stay cord 153 has certain redundant length between per two adjacent blades 151, make the height of sidewall 15 to extend as required or to compress.That is, when reality is used, be housed to paper extraction after, stay cord 153 can fix through mode and the loam cake 11 of knotting, at this moment loam cake 11 is supported on the said paper extraction, and sidewall 15 extends the height (as shown in Figure 2) to adapt to paper extraction under the drive of loam cake 11.Said paper extraction in use; Its height is step-down gradually; Be supported in loam cake 11 on the said paper extraction can be gradually to lower cover 13 near and compression-side wall 15, each other near making sidewall 15 shrink, reduce (as shown in Figure 4) between each blade 151 thereby the volume of host cavity 16 is corresponding.

In this embodiment, the quantity of the stay cord 153 that each sidewall 15 comprises is two.Two said stay cords 153 are arranged at the two ends of sidewall 15 respectively.

In this preferred embodiments, paper-extracting box 10 also comprises many expansion links 17.Many expansion links 17 are installed between loam cake 11 and the lower cover 13 at interval, in order to supplemental support loam cake 11, with fixed cover 11 better.Simultaneously loam cake 11 can be separated with expansion link 17, so that paper extraction is packed in the host cavity 16.In the present embodiment, the quantity of expansion link 17 is identical with sidewall 15 quantity, is appreciated that the quantity of expansion link 17 also can be greater than or less than the quantity of sidewall 15, as long as loam cake 11 is supported on the lower cover 13.According to the operating position of said paper extraction, the length of each expansion link 17 can be under the effect of external force corresponding elongating or shortening so that loam cake 11 along with the change of paper extraction height corresponding moving, thereby change the volume of paper-extracting box 10.

Described paper-extracting box 10 makes the volume of paper-extracting box 10 can do respective change as required through Height Adjustable sidewall 15 is set, and can take under the situation of paper extraction the convenience of depositing and carrying that improves paper-extracting box 10 not influencing paper-extracting box 10.
