Abstract
The utility model relates to an airtight waterproof device for a packing box. The airtight waterproof device comprises an upper box body and a lower box body, buckling faces of both the upper box body and the lower box body are in sealed connection, the lower box body is of a double-layer structure, space between the two layers is filled with a foaming layer, the inner surface of the upper box body corresponds to the inner surface of the lower box body, an outer box capable of being opened independently is arranged on the outer portion of the upper box body, the outer surface of the outer box corresponds to the position of the outer side of the lower box body, an air bag is arranged in the lower box body and provided with a pressure regulating device, one end of an air channel in the pressure regulating device is communicated with the inside of the air bag, and the other end of the air channel extends out of the lower box body and is communicated with the outside. Due to the airtight waterproof device for the packing box, the packing box has waterproofness and air tightness and can be opened repeatedly conveniently and be sealed repeated, the problem that instruments are subject to the influence of outside humidity changes in the storage and transportation process due to the severe weather such as rainstorm is solved, and normal use precision is kept.
Description
Technical field
The utility model relates to a kind of packing chest air-tight water-proof device, for the packing chest to precision instrumentation.
Background technology
Packing chest is used for packing and protection product, and for some accurate instrument and meters, packing chest is very important.Precision instrumentation, in storage, transportation, often can even damage because external environmental condition variation affects service precision, therefore its packing chest has been produced the requirement of air-tightness and water-proofness.
On market at present in all kinds of packing chests of application, some economy and beautiful appearance but water-proofness is poor, some good waterproof performance, but cannot guarantee air-tightness, the packing chest that can guarantee air-tightness and water-proofness having is too heavy again, cannot move and maybe cannot repeat to open, seal with hand, uses inconvenience.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of packing chest air-tight water-proof device, this packing chest air-tight water-proof device makes packing chest both have water-proofness, air-tightness, can repeat easily again to open and use, repeat sealing, guarantee that instrument and meter is in storage, transportation, the impact that or not changed by extraneous humidity because of inclement weathers such as heavy rains, keeps normal service precision.
For overcoming the above problems, concrete technical scheme of the present utility model is as follows: a kind of packing chest air-tight water-proof device, comprise upper box and lower box, and its buckling surface is tightly connected, lower box is double-decker, two-layer between filling foaming body, the inside face of upper box is corresponding with the inside face position of lower box, be provided with the outer container that can independently open in the outside of upper box, the outside face of outer container is corresponding with the outer fix of lower box; In lower box, be provided with air bag, air bag is provided with regulator, and the gas circuit one end in regulator communicates with inside air bag, and the other end stretches out outside lower box, and communicates with the external world.
Described upper box and the buckling surface of lower box are respectively equipped with fastening boss corresponding to position, fastening end face at upper box is provided with sealing joint strip for one week, on the fastening boss of upper box, be also provided with the attaching screw running through, the below of attaching screw is screwed in the fastening boss of lower box.
On the outside of described lower box, along being provided with aluminum alloy pattern plate bound edge, its top is provided with wedge shape boss; Lower edge at outer container is provided with aluminum alloy pattern plate bound edge, and its bottom surface is provided with wedge-shaped impression, and wedge-shaped impression and wedge shape boss fasten.
This packing chest adopts inside and outside box structure, between inside and outside case, connects with foaming.Interior case adopts upper and lower body structure, and casing is that aluminium sheet Combination Welding is shaped; In the junction of upper lower box, adopt sealing band sealing.Sealing band is installed in the seal groove of upper box, then with screw, upper lower box is coupled together, screwing in the process of screw, the distortion that is squeezed of the sealing band between casing, fills up the gap between casing, thereby reaches the effect of sealing.But packing chest reaches after sealing, can cannot easily open because of the inside and outside difference of pressure of casing, therefore design pressure-regulating device.Air bag is placed in interior case, and pressure-regulating device runs through interior outer case, and air bag mouth and pressure-regulating device are tightly connected, air bag communicates with the external world by pressure-regulating device, and does not communicate with internal box, and therefore internal box remains sealing.In the time that external air pressure is greater than the air pressure of internal box, air enters air bag by regulator, makes the internal and external pressure balance of packing chest; In the time that external air pressure is less than the air pressure of internal box, air is discharged air bag by regulator, still makes the internal and external pressure balance of packing chest.
Accompanying drawing explanation
Fig. 1 is the structural representation of packing chest air-tight water-proof device.
The specific embodiment
As shown in Figure 1, a kind of packing chest air-tight water-proof device, comprise upper box 7 and lower box 5, and its buckling surface is tightly connected, lower box 5 is double-decker, two-layer between filling foaming body 2, the inside face of upper box 7 is corresponding with the inside face position of lower box 5, be provided with the outer container 1 that can independently open in the outside of upper box 7, the outside face of outer container 1 is corresponding with the outer fix of lower box 5; In lower box 5, be provided with air bag 3, air bag 3 is provided with regulator 4, and the gas circuit one end in regulator 4 communicates with air bag 3 inside, and the other end stretches out outside lower box 5, and communicates with the external world.
Described upper box 7 and the buckling surface of lower box 5 are respectively equipped with fastening boss corresponding to position, fastening end face at upper box 7 is provided with sealing joint strip 6 for one week, on the fastening boss of upper box 7, be also provided with the attaching screw 8 running through, the below of attaching screw 8 is screwed in the fastening boss of lower box 5.
On the outside of described lower box 5, along being provided with aluminum alloy pattern plate bound edge, its top is provided with wedge shape boss; Lower edge at outer container 1 is provided with aluminum alloy pattern plate bound edge, and its bottom surface is provided with wedge-shaped impression, and wedge-shaped impression and wedge shape boss fasten.
Its working process is: after putting into product, pack sealing joint strip 6 at the seal groove of upper box 7, then cover upper box 7, sealing joint strip 6 is expressed between upper and lower casing with attaching screw 8, reach the effect of sealing.Then cover outer container 1, packaging process completes.
Open while taking out product, open outer container 1, unclamp attaching screw 8, then screw in the jacking screw at 4 jiaos of places, jacking screw is screwing in after upper box 7, continues to screw in to withstand on lower box 5, make to produce gap between upper and lower casing, destroy sealing, so just can open easily upper box 7.Attaching screw 8 on upper box 7 adopts not releasing screw, and screw hangs on upper box 7 all the time, avoids losing.
