Description

A kind of fast-assembling steelframe case

Technical field

The utility model relates to packing chest, relates in particular to a kind of fast-assembling steelframe case.

Background technology

At present, because the profile of industrial products is mostly irregularly shaped, when above-mentioned industrial products are preserved or transported, need to pack to prevent its damage.When industrial products weight is lighter, only needs paper packaging box, but when industrial products weight is heavier, need to adopt wooden case or iron case to pack.Tradition wooden case is to adopt wood lath stitching to form, but this wooden board there will be following problem after using:

(1) leak tightness is poor, needs additional plastic bag to prevent dust or waterproof;

(2) install inconveniently, need to, by artificial with following closely and hammer beats, waste time and energy;

Conventional iron case is because it is cheap and very popular, and its structure adopts angle steel cutting, boring, welding fabrication mostly, then by screw by affixed each structure, but there is following shortcoming in the iron case of said structure:

(1) manufacturing process complexity is loaded down with trivial details;

(2) install and waste time and energy, tens or tens bolts need to be installed when being connected and fixed, cannot reach the requirement of quick assembling;

(3) material usage is large, and cost is higher;

(4) in transit if there is the situation of rocking, because each interstructural connection reliability is poor, cause the each structure of this iron case to rock rear generation distortion, cause the goods in casing to be damaged.

Utility model content

The applicant, for above-mentioned existing shortcoming, is studied improvement, and a kind of fast-assembling steelframe case is provided, and it has quick and easy for installation, saves the advantage of material.

The technical scheme that the utility model adopts is as follows:

A kind of fast-assembling steelframe case, comprises upper frame and underframe, the column of pegging graft between four bights of upper frame and underframe, and lock by resilient pin.

Its further technical scheme is:

Described upper frame and underframe are by also forming the rectangle frame support body that has groove with steel bending forming, have hole in each rectangular edges of described upper frame and underframe;

Described column, by be bent to form " C " shape column that has groove with steel, is arranged symmetrically with and has hole on upper and lower two limits of described column;

Described resilient pin is combined to form " L " shape by vertical end and horizontal ends, and the angle between described vertical end and horizontal ends is 70 °～90 °, is also provided with the clamp with described upper frame, the clamping of underframe phase in vertical end;

The hole having on described upper frame and underframe is circular hole or slotted eye;

The Kong Weiwei circular hole or the slotted eye that on described column, have.

The beneficial effects of the utility model are as follows:

The utility model upper frame, underframe and column all adopt band steel forming work to form, and its strength of material is reliable, and bending strength improves; On upper frame, underframe and column, have the groove that can peg graft mutually simultaneously, save material and reduce cost; Between upper strata framework, underframe and column, by resilient pin, be fastenedly connected, it connects reliable, installs quick and convenient.Column adopts " C " shape, by extending the length on the upper and lower both sides of column, can improve the ability of anti-shearing force of the present utility model and anti-rock, and actv. reduces the rock degree of the utility model in transportation, makes the product in casing obtain maximum protection.

The specific embodiment

Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described.

As shown in Figure 1, the utility model comprises upper frame 1 and underframe 2, as shown in Figure 2 and Figure 3, upper frame 1 and underframe 2 are by also forming with steel bending forming the rectangle frame support body that has groove, in each rectangular edges of described upper frame 1 and underframe 2, have hole, described hole is circular hole or slotted eye; As shown in Figure 1, the column 3 of pegging graft between four bights of upper frame 1 and underframe 2, and lock by resilient pin 4.As shown in Figure 4, column 3 is by being bent to form " C " shape column that has groove with steel, and on upper and lower two limits of column 3, symmetry has hole, the Kong Weiwei circular hole or the slotted eye that on column 3, have.As shown in Figure 5, resilient pin 4 is combined to form " L " shape by vertical end 402 and horizontal ends 403, and the angle between vertical end 402 and horizontal ends 403 is 70 °～90 °, is also provided with the clamp 401 with described upper frame 1, underframe 2 phase clampings in vertical end 402.

Concrete installation process of the present utility model is as follows:

As shown in Figure 1, underframe 2 is placed on smooth ground or table top, the opening of each column 3 is embedded in four bights of underframe 2 by anticlockwise direction, conter clockwise is arranged and is effectively raised reliability and the fastness that upper frame 1 is connected with underframe 2, until the slotted eye 301 on column 3 is mutually corresponding with the slotted eye 201 on underframe 2, resilient pin 4 is now installed in the slotted eye of each correspondence, and the clamp 401 of each resilient pin 4 lock onto in each rectangular edges of underframe 2.As shown in Figure 6, Figure 7, after each column 3 installs, install framework 1, the mounting means of upper frame 1 is identical with underframe 2.

The aperture of the slotted eye 201 on slotted eye 101, underframe 2 on upper frame is greater than the aperture of slotted eye 301 on column 3, is convenient to the clamping between resilient pin 4 and upper frame 1 and underframe 2.

The connection of each inner edge 102 of upper frame employing as shown in Figure 2, "

" shape, this connection mode energy actv. reduces in transit, because casing rocks, makes the deformation that produces between the each structure of each casing, has greatly improved each interstructural connection reliability and anti-shearing stress.

As shown in Figure 8, in this case upper frame and underframe by with steel curved form the rectangle frame support body that there are base and two straight flanges, has groove; In the actual production course of processing, upper frame and underframe can also be by being bent into the rectangle frame support body with base 502 and arc-shaped edges 501 with steel, and described arc-shaped edges 501 is interconnected two, and wherein circular arc 501 limits are connected with base 502 is tangent.

Above-mentioned upper frame 1 and underframe 2 adopt band steel once to bend, and form by welding the rectangle frame support body that has groove, and its strength of material is reliable, and bending strength improves, and actv. has been saved making material, has reduced cost of manufacture.On upper frame, underframe and column, have the groove that can peg graft mutually, save material and reduce cost; Between upper strata framework, underframe and column, by resilient pin, be fastenedly connected, it connects reliable, installs quick and convenient.Column adopts " C " shape, by extending the length on the upper and lower both sides of column, can improve the ability of anti-shearing force of the present utility model and anti-rock, and actv. reduces the rock degree of the utility model in transportation, makes the product in casing obtain maximum protection.

More than describing is to explanation of the present utility model, is not the restriction to utility model, and the utility model limited range is referring to claim, and without prejudice to basic structure of the present utility model in the situation that, the utility model can be done any type of modification.
