Fig. 2 is the structural representation of fixed block of the present utility model.
Embodiment
As Figure 1-Figure 2: a kind of connecting-rod bolts, comprise interconnective nut 1 and the body of rod 2, the described body of rod 2 comprises the stress section 21 connected successively, strengthen section 22 and linkage section 23, be connected by extension 3 between described stress section 21 with enhancing section 22, the curved shape of this extension 3 outer wall, and the diameter strengthening section 22 is greater than the diameter of stress section 21, the radian of described extension 3 is π/15-π/12: if when the radian of extension 3 is less than π/15-π/12, stress section 21 is caused to reduce with the join strength strengthening section 22, and the internal force effect of the generation of extension 3 is reduced greatly, when stress section 21 and enhancing section 22 are stressed, extension 3 is easily out of shape.If when the radian of extension 3 is greater than π/15-π/12, causes the processing cost of extension 3 to promote, do not meet the market demand.
Described enhancing section 22 is connected by changeover portion 4 with between linkage section 23, this changeover portion 4 comprises and strengthens the First Transition section 41 that section 22 is connected and the second changeover portion 42 be connected with linkage section 23, the outer wall of described First Transition section 41 takes the form of inclined plane, the width of described second changeover portion 42 is 10mm-15mm: if when the width of the second changeover portion 42 is greater than 10mm-15mm, second changeover portion 42 process causes the waste of material, substantially increase cost of production, do not meet the market demand.If when the width of the second changeover portion 42 is less than 10mm-15mm, the second changeover portion 42 proposes the effect reduction that arch protection strengthens section 22, and component easily wear and tear and strengthen section 22.
The outer wall of described linkage section 23 is provided with connecting key 230, be connected by fixed block 5 between the outer wall of described second changeover portion 42 and the termination of connecting key 230, this fixed block 5 comprises convergence part 52 and sticking part 51, described convergence part 52 comprises assembly department and main part 521, described assembly department offers the mounting groove 522 of corresponding connecting key 230, the both sides of described main part 521 are provided with stiffening rib 53, one end of this stiffening rib 53 is connected with the outer wall of mounting groove 522, the curved shape in both sides of described sticking part 51, the radian of this sticking part 51 is π/10-π/8, the bottom of described sticking part 51 and the outer wall of the second changeover portion 42 are fitted and connected.
