In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a formula EVAP system access hole inserts soon, includes air hose, air hose's one end is connected with detecting instrument entrance point, and the other end is connected with the quick connector, just air hose is close to quick connector's one end internally mounted and has the reducing joint, air hose is close to quick connector's one end outside cup jointed the solid clamp of outer.
Preferably, the quick-connect plug can be a quick-connect plug male connector.
Preferably, the quick-connect plug can be a quick-connect plug female plug.
Preferably, the caliber of one end of the ventilation hose close to the inlet end of the detection instrument is matched with that of the inlet end of the detection instrument, and the other end of the ventilation hose is reduced through a reducing joint.
Preferably, one end of the ventilation hose, which is far away from the inlet end of the detection instrument, is subjected to diameter change through the reducer union, then is clamped with the quick-connection plug, and then is fastened by the external-fixing clamp.
Compared with the prior art, the beneficial effects of the utility model are that:
1. the utility model discloses in, only need start test instrument once, alright carry out complete leak detection to the EVAP system, improved staff's work efficiency, also prolonged test instrument's life simultaneously.
2. The utility model discloses in, through the reducing joint who sets up, can change the bore of breather hose to make breather hose and quick connector can the phase-match, conveniently connect, thereby can realize the equipment fast.
Drawings
Fig. 1 is a schematic view of the installation structure of the male connector of the quick connector of the present invention;
fig. 2 is a schematic view of the mounting structure of the female connector of the quick connector of the present invention.
In the figure: 1. an inlet end of a detection instrument; 2. an air hose; 3. externally fixing a clamp; 4. a reducer union; 5. A male quick connector; 6. quick connector female.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-2, the present invention provides a technical solution: the utility model provides a formula EVAP system access hole inserts soon, includes breather hose 2, and the one end of breather hose 2 is connected with detecting instrument entrance point 1, and the other end is connected with the quick-connect plug, and breather hose 2 is close to the one end internally mounted who connects the plug soon and has reducer union 4, and the one end outside that breather hose 2 is close to the quick-connect plug has cup jointed outer solid hoop 3.
Wherein, the quick connector can be quick connector male joint 5, if what aim at is the female head of EVAP system, then make quick connector male joint 5 peg graft with the public head of EVAP system, then make the 2 other ends of breather hose peg graft with detecting instrument entrance point 1 of detecting instrument, make detecting instrument again along breather hose 2 aerify to with the EVAP system, detect.
Wherein, the quick-connect plug can be female first 6 of quick-connect plug, when carrying out the EVAP system and examining, if what aim at is the public head of EVAP system, then make female first 6 of quick-connect plug and the public head of EVAP system peg graft, then make the other end of air hose 2 peg graft with detecting instrument entrance point 1 of detecting instrument, make detecting instrument aerify along air hose 2 to with the EVAP system again, detect.
The caliber of one end of the ventilating hose 2 close to the inlet end 1 of the detection instrument is matched with that of the inlet end 1 of the detection instrument, and the other end of the ventilating hose is reduced through the reducer union 4.
Wherein, the one end that the flexible vent pipe 2 kept away from the detecting instrument entrance point 1 passes through behind the reducing of reducer union 4, carries out the joint with the quick-connect plug, then fastens by outer solid clamp 3.
The utility model discloses a theory of operation and use flow: when the EVAP system is detected, if the EVAP system male head is aligned, the quick plug female head 6 is plugged with the EVAP system male head, then the other end of the air hose 2 is plugged with the inlet end 1 of the detection instrument, and then the detection instrument is inflated to the EVAP system along the air hose 2 for detection; if the EVAP system female head is aligned, the quick-connection-plug male head 5 is connected with the EVAP system male head in an inserting mode, then the other end of the air hose 2 is connected with the inlet end 1 of the detection instrument in an inserting mode, and then the detection instrument is inflated to the EVAP system along the air hose 2 to perform detection; if the function of the alarm instrument needs to be detected, an EVAP system access hole can be used, one end of the EVAP system access hole is connected with the EVAP system through a quick connector, the other end of the EVAP system access hole is connected with a detection instrument, the other EVAP system access hole is connected with a standard leakage small hole, gas is introduced through the detection instrument, if the alarm instrument alarms, the alarm instrument functions normally, otherwise, the alarm instrument is abnormal.
