Description

Engine connecting rod convenient to disassemble and assemble Technical Field The utility model particularly relates to an engine connecting rod convenient to assemble and disassemble, and belongs to the technical field of engine connecting rods. Background The connecting rod of the engine is a key component for connecting the piston and the crankshaft, and is used for transmitting the gas pressure born by the piston to the crankshaft and converting the reciprocating motion of the piston into the rotary motion of the crankshaft. In the running process of an engine, the connecting rod needs to bear abrupt change of piston load and inertial force, the working environment is complex, the stress condition is severe, and the traditional engine connecting rod is usually connected by adopting a bolt mode, such as fastening connection of a connecting rod big end and a connecting rod cover through a connecting rod bolt and a nut. When the bolt is disassembled and assembled, a specific tool is required to be used for screwing the bolt and the nut, the operation is complicated, and the bolt can be corroded, slipped and the like, so that the disassembling and assembling difficulty is increased. Patent document CN212615867U discloses an engine connecting rod, "including the connecting rod body, connecting rod lid, go up the axle bush, lower axle bush and location structure, the one end and the connecting rod lid fixed connection of the connecting rod body, the connecting rod body all is equipped with the semicircle groove with the relative one side of connecting rod lid, two the big head hole is constituteed to the semicircle groove, go up axle bush and lower axle bush relative setting and set up in big head hole, go up axle bush and lower axle bush and install in big head hole through location structure, increase axle bush intensity, the easy problem of taking place the deformation when solving the axle bush assembly. However, the engine connecting rod disclosed in the above publication mainly considers increasing the bearing bush strength, solves the problem that the bearing bush is easy to deform during assembly, and does not consider the problem that a special tool is needed for disassembly due to the fact that the big end of the traditional connecting rod is connected with the rod body through a bolt, and is time-consuming and labor-consuming, so that the engine connecting rod convenient to disassemble and assemble is necessary to be researched, and further, the traditional tools such as a spanner are not needed, and the disassembly time is shortened. Disclosure of utility model The utility model aims to overcome the defects of the prior art and provide an engine connecting rod convenient to disassemble and assemble so as to achieve the purposes of shortening the disassembly time and reducing the maintenance cost. The utility model provides an engine connecting rod of convenient dismouting, includes the body of rod and the big end of connecting rod, the one end fixed mounting of the body of rod has the big end of connecting rod, the connecting rod lid is installed to the big end of connecting rod bilateral symmetry, sliding mounting has a fixed section of thick bamboo in the connecting rod lid, fixed section of thick bamboo inside fixed mounting has the dead lever, the one end of dead lever is connected with the handle, the other end symmetry of dead lever sets up telescopic tube, telescopic tube's inside is provided with the spring, and the one end connection dead lever of spring, the other end of spring is connected with the guide post, the one end of guide post extends to telescopic tube's inside. Further, one side slidable mounting of connecting rod lid has the locating pin, one side of locating pin is provided with the magnet piece, be provided with the locating hole corresponding with the locating pin on fixed cylinder and the dead lever, locating pin one end extends to the connecting rod lid inside, and magnet piece and connecting rod lid magnetic connection. Further, the body of rod internally mounted has the cup, be provided with the sealing washer on the cup, the cup extends to the bowl cover inside, and bowl cover and cup threaded connection. Further, the top of the cup body is provided with a glib, one side of the glib is provided with an oil outlet, the lower part of the oil outlet is connected with an oil groove, and the oil groove is distributed inside the rod body in a surrounding mode. Further, a connecting rod big head is fixedly arranged at one end of the rod body, and a connecting rod bearing bush is arranged in the connecting rod big head. Furthermore, the other end of the rod body is fixedly provided with a small connecting rod end, and a piston pin is arranged in the small connecting rod end. Furthermore, connecting rod covers are symmetrically arranged on two sides of the big end of the connecting rod, and grooves corresponding to the fixed cylinders are formed in the connecting rod covers.
