Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1 and fig. 2, the present invention provides a technical solution: a new energy automobile crankshaft connecting rod comprises a connecting rod body 1, a lower shell 3 and a bolt 11, wherein an upper shell 2 is fixedly installed at the bottom end of the connecting rod body 1, arc-shaped grooves 4 are respectively arranged on one opposite side of the upper shell 2 and the lower shell 3, the arc-shaped grooves 4 are used for being sleeved on a rotating shaft of a crankshaft, first clamping grooves 5 are respectively arranged on the left side and the right side of the top of the upper shell 2, nuts 17 are arranged in the first clamping grooves 5, first through holes 6 are formed in the bottom walls of the first clamping grooves 5, screw rods 7 are screwed at the bottom ends of the nuts 17, fixing rings 18 are fixedly installed on the side walls of the screw rods 7, vertical rods 13 are fixedly installed at the bottom ends of the screw rods 7, vertical pipes 8 are sleeved on the side walls of the screw rods 7, as shown in figure 2, the upper end and the lower end of each vertical pipe 8 respectively abut against the bottoms of the fixing rings, the outer wall of round hole 10 is equipped with second draw-in groove 12, the inner of bolt 11 passes round hole 10 spiro union in thread groove 9, the end department of bolt 11 is located second draw-in groove 12, the bottom left and right sides of casing 3 all is equipped with third draw-in groove 15 down, the roof of third draw-in groove 15 is equipped with second through-hole 14, the bottom of pole setting 13 passes second through-hole 14 fixed mounting has fixed block 16, after nut 17 breaks away from the top of screw rod 7 by accident, because the inner spiro union of bolt 11 is in thread groove 9 of riser 8, can avoid going up casing 2 and casing 3 separation down.
Specifically, the top of the nut 17 and the outer end of the bolt 11 are provided with a cross-shaped groove 19, and the cross-shaped groove 19 is provided so that a cross-shaped screwdriver can be inserted into the cross-shaped groove 19 to rotate the nut 17 and the bolt 11.
