Abstract
The utility model discloses an inner support frame for packaging boxes. The inner support frame comprises a cross beam (1), an upright post (2), an upper longitudinal beam (3) and a lower longitudinal beam (4), wherein, the upper longitudinal beam (3), the lower longitudinal beam (4) and the cross beam (1) are in splicing fit with the upright post (2), so as to form a box-shaped space frame. The inner support frame is characterized in that a closed insertion hole (5) in which the upper longitudinal beam (3) is inserted is formed at the upper part of the upright post (2); and spiral lug bosses (6) are integrally formed on the outer surfaces of the cross beam (1), the upright post (2), the upper longitudinal beam (3) and the lower longitudinal beam (4) along the axial lines thereof. The utility model has the advantages of felicitous conception, simple structure, easy assembly, high structural strength, and can efficiently avoid deformation or disassembly during the moving or transportation process of the packaging box, thereby having reliable performance and long service life.
Description
Technical field
The utility model belongs to commodity packaging transportation technology field, specifically, relates in particular to a kind of packing chest inner support frame.
Background technology
Commodity all will be packed before dispatching from the factory, so that be not damaged in carrying with when storing.The carton of regular shape is adopted in the external packing of commodity usually, but because the intensity of carton is limited, and the outline of commodity is often irregular, therefore need in carton, fill in the packing bracing frame, commodity are positioned on the bracing frame,, prevent that commodity from jolting in carton with this intensity that strengthens carton.Heavier for weight, volume is bigger, electromechanical appliance class commodity in irregular shape (as motor bike and accessory thereof), adopts paper tube formula bracing frame to carry out the case internal fixation usually.Chinese patent ZL 200720188737.6 has announced a kind of packing chest paper tube formula inner support frame on November 5th, 2008, its structure such as Fig. 4, shown in Figure 5, last longeron 3, following longeron 4 and crossbeam 1 link to each other with column 2 respectively and form the box-shaped space framework, and be plug in construction between last longeron 3, following longeron 4 and crossbeam 1 and the column 2, described column 2 tops link to each other with last longeron 3 by breach 8, vertically snap in or take out with the convenient longeron 3 of going up.Though above structure has made things convenient for assembly manipulation to a certain extent; but in the process of moving, transporting; because carton inevitably can run-off the straight even upset; cause longeron 3 very easily from breach 8, to come off out; had a strong impact on the structural strength of bracing frame thus; bracing frame deforms easily even disintegrates, and then has lost the protective effect to commodity.
The utility model content
The packing chest inner support frame that provides a kind of structural strength good is provided technical problem to be solved in the utility model.
The technical solution of the utility model is as follows: a kind of packing chest inner support frame, comprise crossbeam, column, go up longeron and following longeron, described upper and lower longeron and crossbeam are pegged graft with column respectively and are cooperated, form the box-shaped space framework, its key is: it is closed jack that the hole that longeron inserts is kept supplying on described column top, described crossbeam, column, on longeron and down the outside face of longeron all be formed with the helix boss that distributes along its axis.
The utility model changes column top and last longeron bonded assembly position into closed jack by traditional breach, going up longeron like this connects reliable, even carton run-off the straight even upset, last longeron can not come off yet, guaranteed the structural strength of whole bracing frame thus, avoided bracing frame in use to deform and disintegrated even.The outside face of each member is set up the helix boss, has not only strengthened the intensity of each member, and whole bracing frame intensity is reliable, and in-use performance and life-span are all secure.
Above-mentioned crossbeam, column, go up longeron and following longeron is the paper tube structure, the convenience of drawing materials like this, cost are low.
In order further to increase Joint strenght, the jack junction of above-mentioned crossbeam and upper and lower longeron and column all with rivet or/and lining cement reinforce the connection.
Beneficial effect: the utility model is skillfully constructed, simple in structure, assembling easily, structural strength is good, can effectively avoid in the process of moving, transporting, deforming or disintegrating not only dependable performance, and long service life.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 removes the structural representation of going up longeron for the utility model.
Fig. 3 is the structural representation of boss in the utility model.
Fig. 4 is the structural representation of background technology.
Fig. 5 is an assembling scheme drawing of going up longeron in the background technology.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As Fig. 1, Fig. 2, shown in Figure 3, the utility model goes up longeron 3 by two crossbeams 1, four root posts 2, two and two following longerons 4 constitute, its center member 1, column 2, go up longeron 3 and following longeron 4 is the paper tube structure, all be formed with along the helix boss 6 of its axis distribution at their outside face.Above-mentioned four root posts 2 are vertically arranged, and by matrix distribution, connection crossbeam 1 between two root posts 2 of same end is in the closed jack that the cooresponding with it column of insertion 2 middle parts, end of this crossbeam 1 are offered.Longeron 4 under connecting between the bottom of two root posts 2 of described the same side, insert in the closed jack of offering corresponding column 2 bottoms the end of this time longeron 4; Connecting longeron 3 between the top of two root posts 2 of described the same side, longeron 3 parallels with following longeron 4 on this, and insert in the closed jack of offering on corresponding column 2 tops 5 end of last longeron 3.Described crossbeam 1, column 2, go up longeron 3 and down longeron 4 form the box-shaped space frameworks, and crossbeam 1, go up longeron 3 and down longeron 4 and column 2 the jack junction all with rivet 7 or/and lining cement reinforce the connection.
Claims (3)
1. packing chest inner support frame, comprise crossbeam (1), column (2), go up longeron (3) and following longeron (4), described upper and lower longeron (3,4) and crossbeam (1) are pegged graft with column (2) respectively and are cooperated, form the box-shaped space framework, it is characterized in that: it is closed jack (5) that the hole that longeron (3) inserts is kept supplying on described column (2) top, described crossbeam (1), column (2), go up longeron (3) and down the outside face of longeron (4) all be formed with the helix boss (6) that distributes along its axis.
