Description

The quick variable case and bag of multilamellar volume

Technical field

This utility model relates to traveling bag, refers in particular to the case and bag of a kind of variable volume.

Background technology

Draw-bar box is easy to use laborsaving, is people's first-selections of going out or travelling, and the volume of usual draw-bar box is certain, no Can arbitrarily according to place object number change tank-volumes, be at most add on case lid one can the structure launched of folding, This structure without positive effect, therefore increases the storage volume of case and bag to increase volume, and the most direct mode is to increase case and bag volume, So, it is necessary to prepare the draw-bar box that volume size is different, not only increase expense, and take up room.

Utility model content

To this end, this utility model provides a kind of quick variable case and bag of multilamellar volume, novel structure, it is skillfully constructed, can basis Need regulating box bag volume size, use more flexible.

For reaching above-mentioned purpose, the technical solution of the utility model is: a kind of quick variable case and bag of multilamellar volume, including main tank Body, case lid, two layer box bodies and surround outward, case lid is detachable cover main box uncovered on, described two layer box body activities peaces On being contained in main box or being uncovered, this two layer box body is the housing of middle part transmission, and described outer encirclement is movably set in two layer box bodies Outside, this outer encirclement is the housing of middle part transmission.

Described main box is molding one locating slot inside the tank wall of open-mouth, on described two layer box body outer walls molding with should The flange of locating slot coupling.

The edge that main box is uncovered is provided with zipper strip, and the edge of case lid is provided with the zipper strip linked with main box.

The bottom of described main box is provided with some clips, and two layer box body inwalls are provided with the card coordinated with this clip Button.

Being equipped with zipper strip on the described outer edge surrounding two sides, the end, top, bottom zipper strip is connected with main box, and top is drawn Chain belt is connected with case lid.

The extended folding flanging in top of described outer encirclement, the top of flanging is formed around the slide fastener being connected with case lid Band.

Four angles of described outer encirclement flanging are provided with adhesive type cloth.

Four angles of described two layer box bodies are provided with and support the outer adjustable fixer surrounding flanging, this adjustable fixer Being made up of pushing and withstanding block and stator, pushing and withstanding block drives stator to move up and down.

Using said structure, case and bag of the present utility model can variable volume size, novel structure, use according to actual needs Flexibly, hommization is more met.

Detailed description of the invention

Below in conjunction with accompanying drawing and be embodied as this utility model is elaborated.

As shown in Fig. 1 to Fig. 7,7A, 7B, the quick variable case and bag of this utility model one multilamellar volume, include main box 1, case lid 2, two layer box body 3 and surround outward 4.

The square box that described main box 1 is made up of bottom 11 and tank wall 12, middle part is accommodation space, can on main box Arranging pull bar, roller, handle and collecting bag etc., the one side that main box 1 is relative with bottom is open uncovered 13, the four of uncovered 13 Circumferential edges is provided with zipper strip 14, along surrounding molding one locating slot 15 inside the tank wall at uncovered 13, is provided with in main box Some clips 16, preferably clip 16 are arranged on four angles of bottom；

Described case lid 2 is detachable to be covered on uncovered the 13 of main box 1, and the edge of case lid is provided with zipper strip 21, supplies and master Casing 1 links together, and the side of case lid is provided with roller；

Described two layer box bodies 3 are optionally movably arranged in main box or on uncovered 13, this two layer box body 3 is middle part transmission Housing, its size is the most corresponding with main box 1 interior size and height with height, on the outer wall of this two layer box body 3 molding one with The flange 31 of main box locating slot 15 coupling, this two layer box body 3 inwall is provided with the buckle coordinated with clip in main box 16 32；

Described outer encirclement 4 is movably set in the outside of two layer box bodies 3, and top is concordant, such as Fig. 4 with the top of two layer box bodies 3 To shown in Fig. 7,7A, 7B, this outer encirclement 4 is the housing of middle part transmission, and the enclosure, outside two layer box bodies 3, can block two layer box bodies 3 With the gap of main box 1 junction, this outer encirclement 4 is pushed up and is equipped with zipper strip 41,42, bottom zipper strip 41 on the edge on two sides, the end For being connected with the zipper strip 14 of main box 1, being fixed outer encirclement 4 bottom, top zipper band 42 is connected with case lid 2, this outer encirclement 4 Can folding, after folding as shown in Figure 6B, can be placed in the collecting bag of casing.

Thereby, two layer box body 3 not used times, the side with flange 31 is placed in main box 1 upward, two layer box bodies Side is kept away on the inwall abutting against main box, and flange 31 is embedded in main box locating slot 15, does not interferes with the use of main box, such as figure Shown in 2, make monolayer casing and use.When needs increase volume, being pulled down by case lid 2, two layer box bodies 3 take out, with flange 31 Side be placed on down on uncovered the 13 of main box 1, flange 31 inlay card of two layer box bodies 3 is on main box locating slot 15, main The clip 16 of box bottom buckles with two layer box body 3 buckles 33, can be connected by two layer box bodies 3 fixing with main box, then will Outer encirclement 4 is set in the outside of two layer box bodies 3, and outer encirclement 4 bottom zipper strip 41 is connected fixing with the zipper strip 14 of main box 1, Top zipper band 42 is connected with case lid 2, forms the two-layer body structure of big volume with this, as shown in Figure 4,5.

Further, the most extended folding flanging 43 in top of outer encirclement 4, the top of flanging 43 is formed around zipper strip 431 can be connected with case lid 2, and four angles of flanging 43 are provided with adhesive type cloth 432, and four angles of described two layer box bodies 3 are provided with Supporting the outer adjustable fixer 34 surrounding flanging 43, this adjustable fixer 34 is by pushing and withstanding block 341 moving up and down and solid Stator 342 forms, and pushing and withstanding block 341 and stator 342 lock together, and after flanging 42 launches, promotes pushing and withstanding block 341, drives solid Stator 342 moves up and protrudes the end face of two layer box bodies 3 and is supported on four angles of flanging 43, is supportted by the flanging 43 of outer encirclement Rising, form the encirclement widened, further expand the volume of casing with this, used time flanging 42 inwardly folding can not utilize clasp to buckle Tight on the inwall of two layer box bodies.

Using said structure, case and bag of the present utility model can variable volume size, novel structure, use according to actual needs Flexibly, hommization is more met.

The above, preferred embodiment the most of the present utility model, it is not limited when being embodied as, therefore in every case depends on Change that claim of the present utility model and description are done or modification, all should belong to the scope that this utility model patent contains Within.
