Referring to Fig. 5 to Fig. 9, on the amalgamation face of described upper holding part 12, be provided with upper groove 7, on described lower holding part 13, be provided with low groove 14, upper holding part 12, lower holding part 13 are provided with gear platform 10 with the connecting portion of insertion section 8, this gear platform 10 is arranged on other 3 faces except amalgamation face, spacing when gear platform 10 inserts left and right side attaching parts end pore for insertion section 8; On the back rib of upper holding part 12, be provided with arc angling 11, the joint face of the plane of upper holding part 12 and insertion section 8 is provided with 2 to 4 rivets or bolt installation position 9, and the rivet installation position 9 on each joint face is 4 rectangular distribution or 3 lineal layouts or 3 Triangle-Profiles.On the amalgamation face of described lower holding part 13, be provided with low groove 14, Fig. 7, in Fig. 8, on lower grip block 3 and the upper grip block 2 amalgamation face when mutual amalgamation, mirror image is symmetrical, descends grip block 3 identical with the shape of upper grip block 2.
In Fig. 3 to Fig. 9, because the axle that the hole forming after upper holding part 12 and the mutual amalgamation of lower holding part 13 and both sides form after the mutual amalgamation in insertion section 8 is respectively perpendicular, the intersect vertical axis of the axle forming after the axis in the hole that therefore, upper groove 7 and low groove 14 amalgamations form and insertion section 8 amalgamations.
Referring to Figure 10, in upper grip block 2, the axis of upper groove 7 is inclination intersection with the axis of upper grip block 2 insertion sections, two ends 8, if lower grip block 3 is corresponding with the shape of upper grip block 2, after the mutual amalgamation of two grip blocks, can meet the crossing needs of left and right side attaching parts and 1 inclination of perpendicular attaching parts.Again in conjunction with Figure 20, when the degree of depth of the upper groove 7 of upper grip block 2 can integral body be put into perpendicular attaching parts 1, and on lower holding part 13, do not set groove 14, and while being flat board, this can make lower grip block 3 and the formed hole of upper grip block 2 mutual amalgamations be partial to top, be the axis in formed hole and the axis of left and right side attaching parts end pore not at grade, now, after upper grip block 2 and lower grip block 3 amalgamations, by upper groove 7 and low groove 14 amalgamations, form the axis in hole and the axis after 8 amalgamations of insertion section different surface beeline each other.
Referring to Figure 11, after 8 one of the insertion sections bending of upper holding part 12 both sides of upper grip block 2, be inclined upwardly, downward-sloping after a bending, make grip block 2 form S shape.Instantly the shape of grip block 3 and its are at once, and the structure of this jointing can adapt to left and right side attaching parts and perpendicular attaching parts 1 tilts to intersect respectively and joining is not the coupled condition of same point.
Referring to Figure 12, the upper holding part 12 of upper grip block 2 is rectangle structure, and there is an insertion section 8 in the left side of upper holding part 12, and right side is evenly distributed with 3 insertion sections 8, and the joining of 3 insertion section 8 axis in right side, on the axis of the upper groove 7 of upper holding part 12.Instantly the shape of grip block 3 and its be at once, and it is vertical and tilt to intersect and joining is not the coupled condition of same point respectively that the structure of this jointing can adapt to a plurality of left and right side attaching partss and perpendicular attaching parts 1.
Referring to Figure 13, the upper holding part 12 of upper grip block 2 is 6 limit shape structures, and there is an insertion section 8 in the left side of upper holding part 12, and right side is evenly distributed with 3 insertion sections 8.Instantly the shape of grip block 3 and its be at once, the structure of this jointing can adapt to a plurality of left and right side attaching partss and perpendicular attaching parts 1 respectively vertical and tilt to intersect and joining be same point state.After two grip block amalgamations, the axis of the axle forming after the axis in the hole being formed by upper groove 7 and low groove 14 amalgamations and 8 amalgamations of each insertion section all intersects at same point, and this point is exactly the joining of longitudinal centerline and insertion section, both sides 8 axis of upper groove 7, low groove 14.
Referring to Figure 14, upper holding part 12 aspects on upper grip block 2 are circular configuration, the left side of upper holding part 12 is evenly distributed with 3 insertion sections 8, right side is also evenly distributed with 3 insertion sections 8, instantly the shape of grip block 3 and its be at once, the structure of this jointing can adapt to that a plurality of left and right side attaching partss and perpendicular attaching parts 1 present respectively that meter word intersects and joining be same point state.
Referring to Figure 15, the structure of this figure and the difference of Figure 14 be, upper holding part 12 both sides all only have an insertion section 8, and the insertion section 8 of both sides tilts crossing with the axis of upper groove 7 in same gradient.The identical point of this structure and Figure 14 is, the axis that two insertion sections 8 form are crossing in same point with the axis of upper groove 7.
At Fig. 3, Fig. 4, Fig. 6, Fig. 9～Figure 11, in Figure 15, because the corresponding insertion section 8 arranging of upper holding part 12 and lower holding part 13 both sides is respectively one, therefore the hole and perpendicular attaching parts 1 interference fit that form after described upper holding part 12 and the mutual amalgamation of lower holding part 13; Described upper grip block 2 and formed axle and be connected left side attaching parts 4 or the pore interference fit of right side attaching parts 5 ends after the mutual amalgamation in insertion section 8 on lower grip block 3.At two matching parts, adopt this fit system can make jointing between perpendicular attaching parts 1, left side attaching parts 4 and right side attaching parts 5, mutually transmit stressed simultaneously, Stability Analysis of Structures, fastness is good.If but adopt other the fit system such as bearing fit, just fastness is in a slight decrease, can not cause the strained condition of jointing to change yet, sometimes for easy for installation, also can adopt bearing fit at two matching parts, and the mode that is aided with mounting fastener strengthens, equally also can reach the object that fastness is good.
Referring to Figure 16, structure and Figure 13 of this figure are basic identical, and the aspect at just upper grip block 2 middle parts is circular.
At Figure 12, Figure 13, Figure 14, in Figure 16, because a side of upper holding part 12 and lower holding part 13 is provided with plural insertion section 8, therefore the hole and perpendicular attaching parts 1 transition fit or the bearing fit that form after described upper grip block 2 and lower grip block 3 amalgamations, form the axes intersect of formed each axle after the mutual amalgamation of axis and each insertion section 8 in hole in same point after upper holding part 12 and the mutual amalgamation of lower holding part 13, and pore transition fit or the bearing fit of each axle and be connected attaching parts end.Because a plurality of attaching partss all exist certain installation error, in general, two matching parts all adopt bearing fit not only make to install more convenient, the strained condition that also can not affect jointing be connected and reliability with each attaching parts.If adopt interference fit at two matching parts, require to improve the working accuracy of two grip blocks, also can increase the installation difficulty of jointing.
Referring to Figure 17, Figure 18, structure in two figure is more similar to the structure in Fig. 5, just on two grip blocks, upper groove 7 and the low groove 14 in holding part 12 and lower holding part 13 is all superficial, two grooves do not wrap perpendicular attaching parts 1 lateral wall completely, and between insertion section 8 and perpendicular attaching parts 1 lateral wall, formed one section of space, go up the not laminating completely of amalgamation face between holding part 12 and lower holding part 13, but reserved certain gap.Because remaining, perpendicular attaching parts 1 is stuck in two grooves, this structure not only can not affect the connection between jointing and attaching parts, the close contact of the insertion section 8 that can also guarantee grip block two ends when amalgamation, so that easier for installation in attaching parts pores inserted in insertion section 8, material can be saved, and the weight of jointing can be effectively alleviated.According to this structure design, in order to save material, expendable weight, can also on the amalgamation face of insertion section 8, along insertion section, 8 axis direction arranges low groove.
