Embodiment
According to drawings and embodiments the present invention is described in further detail below.
As shown in Figure 1, multifunction conjunction of the present invention, comprise the circular upper flange plate (1) and lower flange (2) with internal diameter and external diameter, described upper flange plate (1) has identical internal diameter and external diameter with lower flange (2), described upper flange plate (1) from lower flange (2), be evenly distributed with the different through holes in multiple apertures (15) and through hole (25).
Fig. 2, Fig. 3 are perspective view and the plan structure schematic diagram of described lower flange.Lower flange (2) is provided with loop connecting cover (21), and, perpendicular to lower flange (2) disc and through the center of circle, there are multiple bolts hole (24) medial axis of loop connecting cover (21) on loop connecting cover (21); Described loop connecting cover (21) by being uniformly distributed and interlaced multiple double wedges (22) and recessed tooth (23) forms centered by medial axis, and bolt hole (24) is positioned on recessed tooth (23).Lower flange shown in figure (2) is by four double wedges (22) and four recessed teeth (23), and double wedge (22) outer rim of described loop connecting cover (21) is positioned at the outer radius of lower flange (2).Each recessed tooth (23) has a bolt hole (24), four bolts hole are symmetrical centered by medial axis, disjunct two spiro keyhole positions are in a plane, four bolts hole lay respectively in two highly different planes, the medial axis of the line process loop connecting cover (21) of disjunct two bolts hole and orthogonal.
The structure of described upper flange plate (1) as shown in Figure 4, Figure 5.On upper flange plate (1), be provided with the loop connecting cover (11) that and diameter identical with loop connecting cover (21) shape is less than loop connecting cover (21),, perpendicular to upper flange plate (1) disc and through the center of circle, there are multiple bolts hole (14) medial axis of loop connecting cover (11) on loop connecting cover (11).Loop connecting cover (11) is identical with recessed tooth (23) with double wedge (22) by quantity, centered by medial axis, be uniformly distributed and interlaced double wedge (12) and recessed tooth (13) forms, and bolt hole (14) is positioned on recessed tooth (13).In figure, corresponding with lower flange (2), loop connecting cover (11) also has four double wedges (12), four recessed teeth (13) and four similar bolts hole (14) that distribute.
Described upper flange plate (1) is 215mm with the minimum outer diameter of lower flange (2), and loop connecting cover (11) is 65mm with loop connecting cover (21) minimum constructive height.
Multifunction conjunction of the present invention also comprises connecting bolt (3).When described upper flange plate (1), lower flange (2) are made with connecting bolt (3), tolerance is 2mm, requires high accurancy and precision.
The length of connecting bolt (3) is less than or equal to upper flange plate (1) external diameter, and connecting bolt does not exceed flange plate outside, is placed in outdoor application even if be connected object, and connecting bolt also can not occurred connecting loosening by rainwater rust corrosion because of naked being exposed on the external.
Simple to operate when use, loop connecting cover (21) and loop connecting cover (11) are nested together, undertaken fastening by bolt hole (24) and bolt hole (14) with two connecting bolts (3).In four bolts hole on upper flange plate (1) and lower flange (2), the medial axis that the line of disjunct two bolts hole overlaps through loop connecting and orthogonal, so, be also through medial axis and mutually perpendicular for fixing two connecting bolts (3).
Common flange plate jointing, self does not have mutual active force between two flange plate, can only the two be fixed together by screw.Multifunction conjunction of the present invention, on upper flange plate and lower flange, be provided with respectively loop connecting cover, two loop connecting covers are nested together, just there is certain stability without bolt is fixing, can not make to connect to the external force from non-axial direction and throw off; Use two mutually perpendicular bolts by bolt hole, loop connecting cover to be fixed together, add the be nested effect of combination of loop connecting, can make the surrounding of multifunction conjunction stressed evenly, there will not be each assembly under External Force Acting because unbalance stress damages, the situation of dockingundocking, to use safety.
The present invention can be widely used in various pipe fittings and connects, as, utility pole, house steelframe etc.
