Above-mentioned a kind of cabinet framework with cavity structure, wherein, described mainboard two ends bending edge one side is extended a fillet that outwards turns down, and this fillet overlaps with the long leg segmentation on auxiliary limit and is connected.
Above-mentioned a kind of cabinet framework with cavity structure, wherein, the described cover plate left and right sides is provided with the connection baffle plate, and this connects the end face that the baffle plate two ends hide both sides cavity before and after this cover plate, makes this cavity form a seal.
Above-mentioned a kind of cabinet framework with cavity structure, wherein, described baffle plate is provided with connecting hole.
Above-mentioned a kind of cabinet framework with cavity structure, wherein, described side plate up and down is equipped with low step in position that cavity is set, two ends, and the height of this step is consistent with the height of cavity.
Above-mentioned a kind of cabinet framework with cavity structure, wherein, the upper and lower side center projections of described side plate partly is provided with connecting hole, and it is corresponding with the connecting hole of cover plate both sides to go back connecting hole, is connected by rivet.
Above-mentioned a kind of cabinet framework with cavity structure, wherein, the long limit of described cavity structure is more than the twice of minor face.
Above-mentioned a kind of cabinet framework with cavity structure, wherein, described side plate and cover plate respectively form an extension edge in the cavity structure outside.
Because the utility model has adopted above technical scheme, is made up of left and right side plate and upper and lower cover plate, side plate and cover plate all have cavity shape structure, and form extension edge in the cavity outside.Cavity structure is for repeatedly bending and spot welding connect shaping, the rectangular cavity in its cross section.Side plate and cover plate riveted joint earlier during installation, the back welding forms framework.Intensity is improved.
Concrete structure of the present utility model is further provided by following embodiment and accompanying drawing thereof.
Fig. 1 is an overall structure schematic diagram of the present utility model.
Fig. 2 is the exploded view of Fig. 1.
Fig. 3 is Fig. 1 latus inframedium (for ease of explanation, a side of this side plate baffle plate of having taken away) structural representation.
Fig. 4 is a B part enlarged drawing among Fig. 1.
See also Fig. 1, Fig. 2.A kind of cabinet framework with cavity structure of the utility model is made up of left and right side plate 11,12 and upper and lower cover plate 13,14.
Side plate described in the utility model and covering plate structure are roughly the same, are that example describes in detail below with the side plate.
Ask for an interview Fig. 3, Fig. 4.This side plate comprises a mainboard 21, and the cavity structure 22,23 that is provided with in the both sides, front and back of mainboard.This cavity structure assists limit 31 to constitute by mainboard both ends segmentation inboard 211 and bending edge 212 and thereof; Should assist the limit to comprise the minor face 312 of a long limit 311 and one 90 ° of turnovers, this auxiliary limit 31 tips upside down on segmentation inboard, mainboard both ends and the bending edge thereof, forms a cavity 23 that its cross section is rectangular.
For increasing its intensity, extend the fillet 314 of outside again and again 90 ° of turnovers in a side on auxiliary limit, this fillet overlaps with mainboard both ends segmentation inboard and is connected.Extend a fillet 214 that outwards turns down in mainboard two ends bending edge one side simultaneously, this fillet overlaps with the long leg segmentation on auxiliary limit and is connected.Cavity structure is set to more than growing the twice that limit Y is minor face X.
Be provided with connection baffle plate 41 in the side plate left and right sides, baffle plate is provided with the end face that connecting hole 411 these connection baffle plate two ends hide both sides cavity before and after this cover plate, makes this cavity form a seal.
Equally, be provided with connection baffle plate 81,82 (Fig. 2 is seen in cooperation) in the cover plate left and right sides, baffle plate is provided with the end face that connecting hole 811 these connection baffle plate two ends hide both sides cavity before and after this cover plate, makes cavity form a seal.
Cooperation is referring to Fig. 2, and the position that the two ends up and down of side plate mainboard are provided with cavity is equipped with low step 51,52, and the height of this step is consistent with the height of cavity minor face X, is used for shelving when mounted the rectangular enclosure structure of cover plate both sides.
Upper and lower side center projections part 61,62 at the side plate mainboard is equipped with connecting hole 611,621, and this connecting hole is corresponding with the connecting hole of cover plate both sides, is connected by rivet.
The utility model forms extension edge 91,92 at side plate and cover plate in the cavity outside, when being used for off-premises station, can cooperate the sealing strip on the door to reach the frame sealing function.
The utility model framework is that assembling forms like this: upper cover plate, lower cover, left plate, right plate connect in the connection hole with rivet earlier, form framework.Seam crossing on 8 angles welding then guarantees framework bulk strength and rigidity.
The utility model has the advantage of:
