The utility model provides a technical scheme that its technical problem adopted is: the utility model provides an engine connecting pipe, includes the connecting box, the through-hole has been seted up with the right side upper end of connecting box to the left side lower extreme of connecting box, the internally mounted of through-hole has the go-between, it has the body to peg graft in the inside of go-between, the go-between includes the inboard U type pipe of fixed mounting at the through-hole, the cross section of U type pipe is U type structure, the inside joint of U type pipe has the rubber packing ring, the joint groove has been seted up to the internal surface of rubber packing ring, the inside joint in joint groove has the joint ring, the internal surface of joint ring assembles with the surface mounting of body, the internal surface of U type pipe, rubber packing ring closely laminates the surface.

Furthermore, the cross-sections of the clamping groove and the clamping ring are arc-shaped structures.

Furthermore, small through holes are uniformly formed in the right side of the outer surface of the pipe body on the left side, large through holes are uniformly formed in the left side of the outer surface of the pipe body on the right side, and the diameter of each large through hole is larger than that of each small through hole.

Furthermore, a corrugated body is fixedly arranged on the left side of the outer surface of the pipe body on the left side and the right side of the outer surface of the pipe body on the right side.

Further, the left end of body and the right-hand member fixed mounting of right side body have the joint, the outer fixed surface who connects has the bulge loop.

The utility model has the advantages that: the pipe body that can install through the dislocation when receiving expend with heat and contract with cold and produce deformation, through displacement release internal stress, avoid bursting apart and ageing of pipe body, promote the life of engine connecting pipe.

Detailed Description

The invention will be further described with reference to specific examples, which are intended to be illustrative only and not to limit the scope of the invention. Furthermore, it should be understood that various changes and modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and such equivalents also fall within the scope of the appended claims.

Referring to fig. 1 and 2, the utility model provides a technical solution: the utility model provides an engine connecting pipe, including connecting box 1, through-hole 4 has been seted up with the right side upper end of connecting box 1 to the left side lower extreme of connecting box 1, the internally mounted of through-hole 4 has go-between 5, the inside grafting of go-between 5 has body 2, go-between 5 includes the inboard U type pipe 51 of fixed mounting at through-hole 4, the cross section of U type pipe 51 is U type structure, the inside joint of U type pipe 51 has rubber packing ring 52, joint groove 54 has been seted up to rubber packing ring 52's internal surface, the inside joint of joint groove 54 has joint ring 53, the internal surface of joint ring 53 and the fixed surface assembly of body 2, U type pipe 51, the internal surface of rubber packing ring 52 closely laminates at the surface of body.

The installation through connecting box 1 has certain amortization function, and the installation of go-between 5 can be absorbed through the cooperation of U type pipe 51, rubber packing ring 52, joint ring 53 when body 2 produces deformation because of expend with heat and contract with cold and removes, guarantees inside sealed simultaneously, and the structure of segmentation combination can prevent that the device from collapsing and splitting the damage because of whole deformation extrudees each other.

The cross-section of the snap groove 54 and the snap ring 53 is an arc structure. Through the cooperation of the clamping groove 54 and the clamping ring 53 of the arc-shaped structure, the pipe body 2 can be crossed and moved leftwards and rightwards when small deformation occurs due to expansion with heat and contraction with cold, and the tightness is kept through mutual compression.

Small through holes 7 are evenly formed in the right side of the outer surface of the left pipe body 2, large through holes 6 are evenly formed in the left side of the outer surface of the right pipe body 2, and the diameter of each large through hole 6 is larger than that of each small through hole 7. The noise with different frequencies can be effectively absorbed through the small through holes 7 and the large through holes 6 with different diameters, and the silencer has a silencing function.

The corrugated body 8 is fixedly arranged on the left side of the outer surface of the left pipe body 2 and the right side of the outer surface of the right pipe body 2. Can change the internal stress that body 2 produced because of expend with heat and contract with cold into length change through ripple body 8, avoid the device to burst apart and damage.

The left end of the left side pipe body 2 and the right end of the right side pipe body 2 are fixedly provided with a joint 9, and the outer surface of the joint 9 is fixedly provided with a convex ring 3. Can pass through bolted connection through joint 9 with the engine gas outlet, bulge loop 3 can with the cooperation of rubber gasket, reinforcing sealing performance.

The working principle is as follows: after the device equipment is accomplished, will connect 9 and pass through rubber gasket and bolt fastening in engine air outlet department, the bulge loop 3 makes the leakproofness stronger with the mutual extrusion of rubber gasket, when temperature variation leads to body 2 expend with heat and contract with cold, earlier through the deformation of the ripple body 8 turn into length variation with inside stress, body 2 that changes length can dislocation removal in go-between 5 of connecting box 1, the release internal stress, avoid the mutual extrusion to lead to bursting apart the damage, connecting box 1 simultaneously, little through-hole 7 has certain ability of making an uproar with big through-hole 6, the life of increase connecting pipe.
