Abstract

The utility model relates to a quick connector which belongs to the category of machinery. The quick connector adopts the structure that the main body is injection molded from PA engineering materials, one end of the main body is a corrugated portion which is connected with a pipeline, a first seal ring and a second seal ring are arranged at the other end of the main body and fixed by a locking snap ring after being sleeve joined with a female connector of a quick insert component, the female connector of the quick insert component consists of a female connector bolt and a thread seal ring, and the female connector of the quick insert component is in normal times assembled in the corresponding position on a valve body or an air reservoir. The utility model has the following advantages: the self weight of the connector is greatly reduced; since the quick connector is injection molded with a die, dimensions of the products are highly consistent with each other, thereby improving the drawing performance and the sealing performance of the quick connector when being connected with the pipeline; and the PA engineering materials protect the main body against rust, thereby imparting strong practicability to the quick connector.

Description

Quick inserting joint

Technical field

The utility model relates to mechanical, and particularly a kind of quick inserting joint refers to the quick inserting joint that the automobile-used pipeline of a kind of nylon material connects especially.

Background technique

As everyone knows, automobile-used quick inserting joint mostly is metal product, the single products deadweight is bigger, concerning car load because the quantity of using is more, so it is a lot of that the car load deadweight increases, and uses automation equipment man-hour even product adds, critical size can not be controlled unanimity, metalwork exists still that the pull-off index is on the low side, sealing effect is not good and the hidden danger of long easy-to-rust service time is arranged, and need be improved.

The model utility content

The purpose of this utility model is to provide a kind of quick inserting joint, and it is heavy to have solved joint commonly used self, and critical size can not be controlled unanimity, problems such as pull-off performance, poor sealing performance and easy-to-rust and processing charges height.

The technical solution of the utility model is: it is the male connector part by main body, ring partly reaches fast connector assembly negative joint and partly constitutes, change ring part direction and quantity, can be evolved into bypass structure, three-port structure and three-dimensional three-port structure, in the middle of male connector and ring part, there is a through hole to make the air-flow conducting, two seal rings are enclosed within main body male connector two grooves, two seal rings cooperate with the inwall of fast connector assembly negative joint respectively, reach sealing effect by the negative joint extruding, the bamboo joint structure that is connected with pipeline can effectively increase sealing effect, improves the requirement of pull-out force; Concrete size when joint uses can suitably be adjusted ring by ips and partly get final product.

Structure of the present utility model is: the main body male connector partly adopts PA engineering material injection moulding processing, and an end of this main body is the ring part, and this ring part is connected with pipeline; The other end of main body is provided with first seal ring and second seal ring, and with the socket of fast connector assembly negative joint after fix by the locking snap ring; This fast connector assembly negative joint is made up of negative joint bolt, thread seal circle and locking snap ring, and fast connector assembly is assemblied in relevant positions such as valve body or gas cylinder at ordinary times.Wherein, this joint can be straight-through form, threeway form or three-dimensional threeway form.During use, pipe and ring partly are linked and packed and form the assembly product, the assembly product is connected with fast connector assembly, fast main body of inserting male connector is inserted in the hollow negative joint bolt, first seal ring and second seal ring are pushed by the negative joint bolt, fit with sealing part, guarantee the product sealing, go deep into relevant position locking snap ring and block the end recesses place and guarantee that joint can not throw off.

Advantage of the present utility model is: significantly alleviate the joint own wt, it is strong that mold injection is finished the product size conformity, improved pull-off performance and sealability when being connected with pipeline, and main body adopts the PA engineering material, exempts the hidden danger of corrosion, practical.

Embodiment:

To shown in the accompanying drawing 3, the main body 1 of the utility model quick inserting joint adopts PA engineering material injection moulding processing as accompanying drawing 1, and an end of this main body 1 is a ring part 7, and this ring part 7 is connected with pipeline 8; The other end of main body 1 is provided with first seal ring 12 and second seal ring 13, and with fast connector assembly negative joint 2 sockets after fix by locking snap ring 4; This fast connector assembly negative joint 2 is made up of negative joint bolt 21 and thread seal circle 22, and fast connector assembly 2 negative joints and locking snap ring 4 are assemblied in relevant positions such as valve body or gas cylinder when flat.As shown in Figure 3, during use, pipe 8 is linked and packed with ring part 7 and forms the assembly product, the assembly product is connected with fast connector assembly negative joint 2, fast main body 1 of inserting male connector is inserted in the hollow negative joint bolt 21, and first seal ring 12 and second seal ring 13 are subjected to 21 extruding of negative joint bolt, fit with sealing part, assurance product sealing is goed deep into relevant position locking snap ring 4 and is blocked the end recesses place and guarantee that joint can not throw off.

As shown in Figure 4, the utility model joint can be two logical forms.

As shown in Figure 5, the utility model joint can be the threeway form.

As shown in Figure 6, the utility model joint can be three-dimensional threeway form.
