Abstract

The utility model provides a can satisfy the joint of moulding plastics of weaving noise reduction pipe of assembly requirement. The injection molding joint of the woven noise reduction pipe comprises a main body, wherein small bosses matched with square holes at corresponding positions of an air filter shell in shape are respectively arranged on the upper side and the lower side of the main body; the main body is provided with a guide rib matched with the shape of a guide chute at the corresponding position of the air filter shell. The utility model can meet the requirement of assembling strength through the clamping matching of the small bosses at the upper and lower sides and the square holes; the guide ribs on the left side and the right side are matched with the guide sliding grooves, so that the assembly guide effect can be achieved, and the guide ribs can also achieve the mistake proofing effect due to the asymmetrical arrangement; for the special-shaped woven pipe, the flying wing-shaped structure at the tail part of the joint can be conveniently held by a worker, and the assembling effect is achieved.

Description

Injection molding joint for weaving noise reduction pipe

Technical Field

The utility model relates to a connect, especially relate to an automobile air intake system weave the joint of moulding plastics of falling noise pipe assembly.

Background

The woven noise reduction pipe assembly consists of a woven noise reduction pipe and injection molding joints at two ends. The woven noise reduction pipe can reduce the air inlet noise of the engine. The woven noise reduction pipe is assembled and connected with the air inlet, the air filter and other parts through injection molding joints. When the existing injection molding joint is assembled, the front surface and the back surface are easy to assemble and reverse; the guide mechanism is not needed, and the assembly is not easy to be completed at one time; and for the special-shaped braided tube, workers are difficult to hold the injection molding joint tightly, and the assembly is very difficult.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that a can satisfy the assembly requirement weave the joint of moulding plastics of falling the pipe of making an uproar.

The utility model provides a technical scheme that technical problem adopted is: the injection molding joint of the woven noise reduction pipe comprises a main body, wherein small bosses matched with square holes at corresponding positions of an air filter shell in shape are respectively arranged on the upper side and the lower side of the main body; the main body is provided with a guide rib matched with the shape of a guide chute at the corresponding position of the air filter shell.

Further, the guide ribs are arranged on the main body in an asymmetric arrangement mode.

Further, the tail of the main body is arranged into a flying wing-shaped structure.

The utility model has the advantages that: the utility model can meet the requirement of assembling strength through the clamping matching of the small bosses at the upper and lower sides and the square holes; the guide ribs on the left side and the right side are matched with the guide sliding grooves, so that the assembly guide effect can be achieved, and the guide ribs can also achieve the mistake proofing effect due to the asymmetrical arrangement; for the special-shaped woven pipe, the flying wing-shaped structure at the tail part of the joint can be conveniently held by a worker, and the assembling effect is achieved.

Detailed Description

As shown in fig. 1-9, the utility model discloses a joint of moulding plastics includes main part 1, is provided with a little boss 2 respectively in main part 1 upper and lower both sides, as shown in fig. 2, is provided with quad slit 5 in the department of correspondence of empty filter casing 7, little boss 2 and quad slit 5's shape phase-match, the utility model discloses a joint of moulding plastics adopts the lock to be connected with empty filter casing 7, and after the lock assembly, little boss 2 sinks into quad slit 5, constitutes the fitting relation, satisfies the pull-out power requirement.

The main body 1 of the injection molding connector is provided with guide ribs 3 in an asymmetric arrangement mode, a guide chute 4 is arranged at a corresponding position of the air filter shell 7, the guide ribs 3 are matched with the guide chute 4 in shape, and the injection molding connector and the air filter shell 7 are guided and positioned in assembly. The above-mentioned guide ribs 3 may be asymmetrically arranged on both left and right sides of the main body 1 as shown in fig. 5.

The knitted noise reduction pipe 8 is made by the working procedures of steel wire rewinding, cotton yarn doubling and the like, and is soft in texture. For the specially-shaped woven noise reduction pipe, the structure of the injection molding joint has a large influence on the connection and assembly of the woven noise reduction pipe 8. The utility model discloses an injection moulding connects and sets the 1 afterbody of main part to flying wing shape structure 6, is favorable to the workman to hold injection moulding joint like this, reduces the assembly power, and its outward appearance of high discernment degree can play the mistake proofing effect simultaneously.

During assembly, a worker holds the flying wing-shaped structure 6 at the tail of the injection joint main body 1, pushes the part forwards, and enables the guide ribs 3 on the two sides of the injection joint main body 1 to move along the guide sliding grooves 4 of the air filter shell 7 until the small bosses 2 on the upper side and the lower side of the main body 1 sink into the square holes 5 of the air filter shell 7, and the assembly connection is finished.
