Abstract

The utility model relates to a packing box with a telescopic function, which is composed of a box cover, a box body and a box bottom, wherein the box body is divided into two to four segments, a belly band made of channel steel is arranged on each segment of the box body, and all the segments of the box body are connected together to form an integral telescopic box body by a telescopic mechanism in the box body; a boxing opening is arranged on the box cover, and the box bottom is provided with a discharge door. When the utility model is used for loading and transporting bulk cement, a special transporting vehicle for cement is not needed and a cement storage tank does not need to be arranged in a construction site. The use of the packing box with a telescopic function is very convenient. An empty box after used can be stored by folding for recycle. The packing box with a telescopic function can be widely used for packing various powdery and granular products, such as graphite powder, titanium white powder, black carbon, plastics, etc.

Description

The concertina type packing chest

The utility model relates to a kind of packing chest with Telescopic, is used for the packing of powdery or granular product, is specially adapted to do the packing chest of bulk cement product.

Cement is the primary raw material of civil engineering, and packed and in bulk two kinds of forms are arranged when cement products dispatches from the factory.The packing that bagged cement uses can only be used once usually, and need unpacking in the use, the bag that falls are cumbersome; In addition, bagged cement is normal in transit damaged, causes the waste of cement more serious.At present, bulk cement is promoted the use of for many years, but also has a lot of inconvenience: bulk cement needs special transport vehicle to transport, and the pneumatic process cement loss of unloading is bigger, and also there is certain problem in environmental protection; Particularly the user need have the cementing tank that stores cement, and the capacity of its jar also will mate with a freight volume.Therefore, vigorously promote the use bulk cement now and must solve above-mentioned inconvenience.

The purpose of this utility model provides a kind of concertina type packing chest, is used as the packing chest in bulk cement transportation, the use, makes it convenient transportation, storage, thereby can quicken promoting the use of of bulk cement.

The utility model is achieved in that at the bottom of the concertina type packing chest is by case lid, casing, case to be formed, be characterized in that casing is divided into the 2-4 section, make loincloth with channel-section steel for every section, the telescoping mechanism that connects and composes by folding around in the casing and boxboard couples together the whole flexible casing of formation with each section of casing loincloth.Be provided with the vanning mouth on case lid, the bottom at the bottom of case is provided with Dump gate.The utility model adopts said structure, and when dress cement, whole box body trails, and has guaranteed volume.After cement was laid down, the foldable Cheng Yuansi of a whole box body/height transported repeated use back after the recovery.

Below in conjunction with accompanying drawing the utility model is described further:

Fig. 8 is the flat device structural representation of drawing together of the present utility model;

Fig. 9 is a boxboard convex rib structure scheme drawing of the present utility model;

Figure 10 is the A-A cutaway view of Fig. 9.

The utility model 5 is formed at the bottom of by case lid 1, casing and case.The casing of this embodiment is three sections, and promptly casing I section 2, casing II section 3, casing III section 4, every section are made the square frame loincloth with channel-

section steel

6, and 5 usefulness angle steel 7 are made the square frame loincloth at the bottom of case lid 1 and the case.Each section of casing loincloth is coupled together with the telescoping mechanism that boxboard 11 connects and composes by the folding (part 13, part 12) around in the casing, form whole flexible casing.Vanning mouth 9 is arranged on case lid 1, and 5 bottoms are provided with Dump gate 10 at the bottom of the case.For guaranteeing the intensity of boxboard 11, boxboard 11 is provided with convex reinforced rib 8, the brace panel 20 that the useful rivet in reinforced rib 8 places is fixing.

Telescoping mechanism concrete structure of the present utility model is one side of two blocks of boxboards 11 to be connected deployable or folding with folding 12, and the another side of these two blocks of boxboards 11 is connected with adjacent separately loincloth by folding 13 respectively.Whole box body is trailed (Fig. 1) or foldable one-tenth Fig. 2 state under the telescoping mechanism effect.

For making the utility model (Fig. 1) fixed in shape under the state that trails constant, installation positioner 14 between two foldings 13 of the channel-section steel 6 loincloth inboards of this packing chest, steady arm 14 is a manual rotary, connects positioning end by manual knob and constitutes.Positioning end is a long slab shape.Half-twist, positioning end are pushed down two foldings 13, and it can not be rolled over, and promptly casing just can not be foldable, can only keep the state that trails.

Pack into behind the cement for preventing the utility model, because weather variation of temperature or cement moisture content exceed standard, cement is " rise baking ", " Tower Bridge " in case, needs be provided with in casing anti-baking device, promptly penetrates the anti-baking device that the stirring-head 16 that driven by wrench shaft 15 constitutes at channel-section steel 6 loincloth places.Thereby cement " baking ", " Tower Bridge " in casing have been prevented effectively.

5 adopt waveform configuration at the bottom of the case of the present utility model, and optional three waveforms constitute, and are provided with Dump gate 10 at the place, inclined-plane of two side wave shapes, adopt the pressure at the bottom of this structure can reduce case, are convenient to discharging.

Because cement is flour, the taper accumulation is easily formed on the top in the case of packing into.Therefore, need in case lid 1 of the present utility model, to be provided with and draw together flat device, draw together flat device and constitute by fixedly drawing together flat cutter 18 on the circular knife rest 17.19 for driving the rotary jack of drawing together flat device.Flat device is drawn together in driving can make the cement of pouring in the case in case

The utility model is reasonable in design.Load and transport bulk cement with the utility model, do not need specific cement special vehicle, any type of car and boat all can transport.The construction site need not be provided with the cementing tank of storage cement, and is very easy to use.Deposit with afterwards empty van is foldable, recycle.Empty van only for full case high 1/4th, convenient transportation and stacking.The utility model can be widely used in the packing of various powderies such as graphite powder, titanium dioxide, carbon black, plastics, granular product.
