A pre-installed quick-connect nylon pipe threaded fitting for automobiles

Abstract

This utility model discloses a pre-installed quick-connect coupling for automotive nylon pipe threaded joints, relating to the field of automotive parts technology. It includes a quick-connect body and a threaded joint. The threaded joint includes a pipe body with a nut boss in the middle of its outer side wall, a threaded section at the lower end of the outer side wall, and a plug at the upper end. The quick-connect body has a socket that matches the plug. After the threaded joint is pre-installed in a preset position, the socket of the quick-connect body is then fixedly inserted into the plug. In this utility model, the threaded joint has a machined mounting groove, and a retaining ring is installed inside the quick-connect body.

Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, specifically a pre-installed quick-connect nylon pipe threaded connector for automobiles. Background Technology

[0002] Currently, quick-connect couplings on the market are generally of the elbow, tee, and cross types, and are typically provided to customers as an assembly. Installation requires manual tightening of the threads with a wrench to achieve a secure fit. This installation method has the following significant limitations:

[0003] 1. Low installation efficiency: It is impossible to use pneumatic tools such as air guns for quick assembly, and manual operation is required, which increases the operation time and labor costs.

[0004] 2. High risk of interference: When the installation space is limited or there are other components around, the operating space required for manual tightening is relatively large, and it is very easy for the tool or connector to interfere with the surrounding components, which may lead to installation difficulties, poor sealing or even damage to the equipment. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a pre-installed quick-connect coupling for automotive nylon pipe threaded fittings. The threaded fitting has an installation groove, and a retaining ring is installed inside the quick-connect body. When the quick-connect body is pressed onto the threaded fitting, the retaining ring can quickly fix the installation groove. Workers can use an air gun to quickly install the threaded fitting, which speeds up the process and avoids the problem of interference and collision between the product and other parts during the installation of the fitting.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is: a pre-installed quick-connect coupling for automotive nylon pipe threaded joints, comprising a quick-connect body and a threaded connector. The threaded connector includes a pipe body, a nut boss is provided in the middle of the outer wall of the pipe body, a threaded section is provided at the lower end of the outer wall of the pipe body, and a plug portion is provided at the upper end of the pipe body. The quick-connect body has a socket portion that matches the plug portion. After the threaded connector is pre-installed in a preset position, the socket portion of the quick-connect body is then fixedly inserted into the plug portion.

[0007] A further improvement is that: the outer side wall of the plug portion is provided with a first mounting groove, a retaining ring is installed in the first mounting groove, and the inner side wall of the socket portion is provided with a slot that matches the retaining ring.

[0008] A further improvement is that the retaining ring is provided with an opening.

[0009] A further improvement is that a tapered guide section is provided at the upper end of the plug.

[0010] A further improvement is that a second mounting groove is provided at the bottom of the nut boss, and a first sealing ring is installed in the second mounting groove.

[0011] A further improvement is that the outer wall of the plug portion is provided with several third mounting grooves, and a second sealing ring is installed in the third mounting groove.

[0012] A further improvement is that there are two third mounting slots, both located below the first mounting slot.

[0013] A further improvement is that the quick-connect body is a bent tube structure.

[0014] The beneficial effects of this utility model are as follows:

[0015] In this invention, the threaded connector has an installation groove, and the quick-connect body has a retaining ring installed inside. When the quick-connect body is pressed onto the threaded connector, the retaining ring can quickly fix the installation groove. Workers can use an air gun to quickly install the threaded connector, which speeds up the process and avoids the problem of interference and collision between the product and other parts when installing the connector.
