Abstract

An assembled polygonal frame is composed of n prisms and n transverse beams. The end of transverse beam is inserted in the end of prism for linking them together. Said prism is an open splayed section formed integrally by symmitrical two 2-step right-angle bent plates. The both ends of said prism have two-way inserting parts perpendicular to said transverse beam and made up of two one-step right-angle bent plates. Said transverse beam is a three-step right-angle bent plate with an open rectangular cavity for linking said two-way inserting part.

Description

A kind of assembled polygonal frame

The present invention relates to a kind of cabinet framework, relate in particular to a kind of assembled polygonal frame.

Existing relatively representative type build-up type framework, disclosed as German patent DE 33 44 598, be a cuboid or square, this framework mainly is made up of 12 prisms and eight trident spares.Prism is to be pressed by the sheet metal progressive type to process, and as shown in Figure 1, prismatic 1 is to be folded into one by a sheet metal to be top corner part with rectangular enclosure 11 extend the section bar of different edged surfaces 12,13 respectively to the two sides, and the rectangular surfaces of cavity is provided with some mounting holes.As shown in Figure 2, trident spare 2 is used for three prisms 1 of angle connection, that is: the bifurcated 21 of trident spare 2 inserts the rectangular enclosure 11 of each prism 1 respectively, also be provided with the corresponding one by one connection holes of mounting hole on the bifurcated 2 with prism 1, and make bolt enter prismatic mounting hole to be attached directly on the connection holes of bifurcated 2, make prismatic 1 to be fixedly connected with bifurcated 2.

Said structure is because the prism of framework adds the specialized equipment that needs man-hour expense very high for top corner part has the structure of rectangular enclosure, and, the processing of trident spare must be striden this metal manufacture field and just can be accomplished, so its cost of production costliness very, and the cost of trident spare is also higher.In addition, framework maximum weighted point (referring generally to carry or the following force position of conducting oneself with dignity and producing of lifting state) bears by the mounting hole on bolt and the corresponding prism unavoidably, and its shear strength of the mounting hole on the sheet metal is relatively poor, if so in the additional weld nugget in prismatic bifurcated junction, the just greatly reduction of the reliability of its intensity with trident spare.In addition, the diagonal line precision of most important four vertical surface of framework and reliability thereof depend on the positional precision and the bore clearance of associated components mounting hole, the relative error of general position precision must rely on the amplification bore clearance and adjust, and the gap is big, the assembly precision poor reliability; The gap is little, processing and assembling difficulty.

The object of the present invention is to provide a kind of assembled polygonal frame, it not only satisfies the practical application needs in intensity, precision and unfailing performance, can make again that structure is simpler, manufacturing is easier and cost is cheaper.

The object of the present invention is achieved like this, a kind of assembled polygonal frame, it is characterized in that, it is made of n root prismatic 3 and n root crosspiece 4, the end of crosspiece 4 is plugged on the end of prism 3, described prismatic 3 be one-body molded by two blocks of second order elbow bend flaps 31 of symmetry be the Eight characters opening section bar of a drift angle in 90～180 scopes, its cross section is

Shape, and the both ends up and down that make this prism 3 are contained one respectively and are symmetrical arranged the two logical plug-in units 32 vertical with prismatic 3 that constituted with two blocks of single order elbow bend flaps 321, each single order elbow bend flap 321 of these two logical plug-in units 32 is formed by first plate 3212 and second plate 3211, and make first plate 3212 stretch out also integrally formed from prismatic 3 end faces 33 from a side 311 and second plate 3211 of the Eight characters opening of prism, described crosspiece 4 is by first 41, second 42, the 3rd 4 and fourth face 44 are integrally formed as three rank elbow bend flaps with rectangular aperture cavity, and its cross section is

Shape, the single order elbow bend flap 421 of described two logical plug-in units is inserted in the rectangular aperture cavity of described crosspiece one end, and make first 41 first plate 3212 of crosspiece 4 paste fixing with single order elbow bend flap 321, the fourth face 44 of crosspiece 4 and second plate 3211 of single order elbow bend flap 321 paste fixing, seal this rectangular aperture cavity.

Above-mentioned assembled polygonal frame, wherein, the limit end vertical extent one right angle bending plate 45 of the fourth face 44 of crosspiece 4, and one-body molded.

Above-mentioned assembled polygonal frame, wherein, the α angle can be 90 °, and this moment, n just was 4, and described assembled polygonal frame is a rectangular frame.

Above-mentioned assembled polygonal frame, wherein, the α angle can be 120 °, and this moment, n just was 6, and described assembled polygonal frame is a hexagonal-shaped frame.

Owing to adopted above-mentioned technical solution, the assembling back all forms the sealing rectangle in the vertical stressed arbitrary cross section of connecting portion, make framework have higher bending resistance torsional strength, more because prism structure has circulated the function of threeway dexterously, make the maximum force of framework directly act on prism itself, just can guarantee the strength reliability of framework at maximum weighted point place so need not additional weld nugget.One aspect of the present invention has improved assembly precision and reliability thereof, greatly reduces the difficulty of processing and assembling on the other hand, and framed structure and manufacturing process are simplified greatly, has reduced cost of development, helps large-scale standardized production.

The present invention is further illustrated below in conjunction with embodiment and accompanying drawing.
