Fig. 2 to Fig. 4 is the assembling process schematic representation of rack construction shown in Figure 1; Wherein Fig. 2 representes first crossbeam and column are pegged graft, and Fig. 3 representes second crossbeam and column are pegged graft, and Fig. 4 representes square tube and column are fixed; And the view direction of Fig. 2, Fig. 3 is identical, and inequality with Fig. 4.

Embodiment

Referring to rack construction shown in Figure 1, it mainly comprises many root posts 1 of being disposed in order into a circle, is connected square tube 2 on every root post 1, is connected the crossbeam 3 between adjacent two root posts 1, said square tube 2 and crossbeam 3 separation.One end of said crossbeam 3 offers two square openings, is formed with two gear shapings on the said column 1 accordingly, makes between said column 1 and the crossbeam 3 being connected of realizing through pegging graft dismantling; The bearing of trend that the end of said crossbeam 3 has with crossbeam 3 is domatic 30 of acute angle; Said square tube 2 has a pair of

relative side

2a, 2b; End and column 1 formed space that said square tube 2 is inserted adjacent two crossbeams 3, and domatic 30 with said a pair of

relative side

2a, 2b in towards this domatic 30 one against.

Be described in detail in the face of above-mentioned rack construction down.

Visible from Fig. 2, Fig. 3, Fig. 4, be formed with gear shaping 11 on the said column 1, offer the square opening 31 corresponding on the said crossbeam 3, through gear shaping 11 is inserted the grafting that square openings 31 can be realized column 1 and crossbeam 3 with gear shaping 11.Corresponding to the grafting of each root crossbeam 3, need the plug in structure of two secondary gear shapings 11 and square opening 31.On the said column 1, be provided with many places gear shaping 11, can many crossbeams 3 be connected on the column 1 accordingly, perhaps connect crossbeam 3 at the height of specific column 1 as required along short transverse.

The below that is positioned at gear shaping 11 on the said column 1 is formed with the surperficial bearing of trend flange 12 vertical with column 1 bearing of trend, and the lower surface of the top of said flange 12 and crossbeam 3 is fitted, and bottom support is on the flanging 13 of column 1.After crossbeam 3 hung up gear shaping 11,12 pairs of crossbeams 3 of flange played the picking-up effect, were not only to lean on gear shaping 11 stressed.

Said domatic 30 form 45 ° angle with the bearing of trend of crossbeam 3, so the crossbeam 3 of square tube 2 both sides is vertical each other arranges, more help stressed evenly, also meet the cube rack construction that illustrates four root posts 1.Said domatic 30 the side away from crossbeam 3 ends has convex edge 32, and stretch out towards the inboard of rack construction said convex edge 32, and position-limiting action can further be played to square tube 2 in said convex edge 32.In the present embodiment, and be not only domatic 30 position, but all be formed with described convex edge 32 on the bearing of trend of overall beam 3.Because said crossbeam 3 is sheet metal part, so convex edge 32 is two sides of sheet metal part, and stretch out towards the inboard of rack construction convex edge 32, can increase the intensity of crossbeam 3, does not also influence the attractive in appearance of crossbeam 3.

Offer square hole 14 on the said column 1; The position of the square hole 14 on the said square tube 2 on the corresponding column also offers square hole (not illustrating with reference character among the figure); Can realize the locking of square tube 2 and column 1 through square neck screw 4, column 1 outside no screw terminal is more attractive in appearance.

Assembling process in conjunction with Fig. 2, Fig. 3, the visible above-mentioned rack construction of Fig. 4:

Referring to Fig. 2,, first crossbeam 3 and column 1 are passed on left square opening 31 peg graft, and the lower surface of crossbeam 3 is supported on the flange 12 of column 1 with cooperating of gear shaping 11 along dotted line direction among Fig. 2.

Referring to Fig. 3, similar with Fig. 2, along dotted line direction among Fig. 3, pegged graft in second crossbeam 3 and column 1 right side.

Next, according to actual needs, when this rack construction need be born bigger power, crossbeam 3 is pegged graft along the short transverse of column 1 more.

Referring to Fig. 4, square tube 2 is inserted between crossbeam 3 and the column 1, through square neck screw 4 square tube is locked on the column 1.

Why above-mentioned rack construction can not fall apart, and big strength can be arranged, and key is the spacing of direction and the shearing force of having used self material, and is not to be that screw or welding give.Gear shaping is with after square hole cooperates between column and the crossbeam, and movable direction has just had only a direction, the principle of identical axle and hole cooperation.As long as solve this activity direction, just can it be limited fully.Square tube has just played such effect, and when crossbeam will be deviate from, square tube was withstood crossbeam, can't throw off.The inclined-plane of angle has all been done in the design of crossbeam, both sides, the inclined-plane that comes to this, and it can form an extruding force with square tube when crossbeam will be deviate from, and wants to deviate from, and card is tight.Finally, formed the stronger new frame structure of a kind of bearing capacity.Such design is used, and has promptly solved client's installation question, all breaks up to the client, and the client directly assembles in the equipment erecting bed and gets final product.The shearing force of material self is leaned in the load-bearing aspect, and the traction of power each other makes rack under big load-bearing, also can not be out of shape.

Though the utility model with preferred embodiment openly as above; But it is not to be used for limiting claim; Any those skilled in the art are in spirit that does not break away from the utility model and scope; Can make possible change and modification, so the protection domain of the utility model should be as the criterion with the scope that the utility model claim is defined.
