Description
Technical field
It the utility model is related to a kind of Quick joinker for pipeline, more particularly to a kind of automatic fast quick access for leak detection
Head.
Background technology
, it is necessary to fill liquid or gas waits until interiors of products as function in the field such as household appliances product air-conditioning or refrigerator
Part, so needing to leak hunting to these parts, typically pipeline can be connected by aerating device by a snap joint, it is entered
Row is inflated to be detected.In the prior art, hand pull type snap joint is typically had, insertion tube is opened by pulling handle
Part, handle is then pulled again and is compressed, is detected.This kind of joint, when handle compresses, it can not judge whether to be pressed into place,
Completely by virtue of experience, and during air pressure continues to increase, if press-in is not in place, it is more likely that sudden disengaging, production occurs
It is raw dangerous, and typically pipe fitting is locked by steel ball part inside it, abrasion is produced to pipe fitting.
The content of the invention
In order to overcome the above-mentioned deficiency of prior art, the utility model provides a kind of leakage that is used for without abrasion to pipe fitting and examined
The automatic snap joint surveyed.
The technical scheme in the invention for solving the technical problem is：
A kind of automatic snap joint for leak detection, including adapter body, are connected to the air inlet of adapter body one end
Joint, the lock-on connection for being connected to the adapter body other end, are communicated with venting channels between lock-on connection and inlet suction port, it is special
Sign is：Described lock-on connection includes circumferentially distributed more than one fixture block, and the opposite face of the fixture block forms locking face,
Described fixture block relative can gather locking or relative separation unblock.
Preferably, fixture block inner ring is provided with the first sealing ring.
Preferably, adapter body includes connection inlet suction port and centre is provided with the adapter of inlet channel, is connected to
Adapter periphery and the housing of hollow setting, pushing sleeve is connected with by pushing sleeve spring on adapter, set is provided with fixture block on pushing sleeve
Cover for seat, housing upper end are provided with end cap set, and described fixture block inclined-plane is connected between described fixture block cover for seat and end cap set.
Preferably, being hingedly attached to the housing with depression bar, and return unit is provided between depression bar and housing, the connection of described depression bar
Push rod, described push rod wear housing connection pushing sleeve.
Preferably, being connected with vent piston by piston spring among adapter, described pushing sleeve is set in described
In vent piston, described vent piston upper end is provided with seal washer, and locking is formed between described vent piston and fixture block
Space, described inlet channel, vent piston form described venting channels.
Preferably, the second sealing ring is provided between fixture block cover for seat and pushing sleeve.
Preferably, between inflation piston and pushing sleeve, the 3rd sealing ring is provided between pushing sleeve and housing.
Preferably, the upper end inner surface setting of fixture block cover for seat has the first inclined-plane, end cap set upper side inner surface setting is the
Two inclined-planes, the upper and lower ends outer surface of the fixture block are arranged to fixture block inclined-plane, and described fixture block inclined-plane contradicts described in connection respectively
The first inclined-plane and the second inclined-plane.
Pipe fitting is inserted between fixture block, the locking space that vent piston is formed.
In non-mode of operation, fixture block is promoted by fixture block cover for seat and end cap set and is mutually gathered locking, and pipe fitting can not insert, and needs
When detecting, depression bar is depressed, the push rod of depression bar promotes pushing sleeve compression pushing sleeve spring to move downward, drives the pressure being connected on pushing sleeve
Block set is moved downward, and because fixture block inclined-plane is connected between fixture block cover for seat and end cap set, fixture block is separated from each other respectively, and pipe fitting is inserted
Enter, be inserted at the seal washer of vent piston upper end.Depression bar is discharged, vent piston is resetted by piston spring, to the end of pipe fitting
Portion is sealed.Due to the reset response of pushing sleeve spring, pushing sleeve, which resets, promotes fixture block cover for seat to reset, and the first of fixture block cover for seat upper end
Slope driving fixture block mutually gathers locking pipe fitting.The second sealing ring between pushing sleeve and fixture block cover for seat is because squeezing action is to pipe fitting
Carry out side seal, the first sealing ring in fixture block passes through vent piston because squeezing action carries out side seal to pipe fitting
Carry out end part seal of the seal washer of upper end to pipe fitting.
After pipe fitting insertion connection, it is inflated by inlet suction port, gas passes through the inlet channel by adapter, logical
Gas piston formed venting channels enter pipe fitting, in gas replenishment process, gas pressure is bigger, then by adapter to vent piston with
And the pressure of pushing sleeve is about big, then pushing sleeve is acted on fixture block by fixture block cover for seat so that the effect of the locking to pipe fitting of fixture block is stronger,
Be not in that gas pressure is bigger, the effect that pipe fitting easily pops out, by seal washer and the second sealing ring to pipe fitting
Sealing effectiveness is also better.
The beneficial effects of the utility model are：The utility model is locked by the fixture block that can mutually clamp to pipe fitting
Tightly, and by the rational design to whole joint, realize that the blowing pressure is bigger, and degree of blocking is better, and easy to operate.
Brief description of the drawings
Fig. 1 is cross section structure diagram of the present utility model.
Fig. 2 is partial cross structural representation of the present utility model.
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
Embodiment
As shown in Figure 1, 2, a kind of automatic snap joint for leak detection, including adapter body, are connected to joint master
The inlet suction port 16 of body one end, the lock-on connection for being connected to the adapter body other end, are connected between lock-on connection and inlet suction port
There are venting channels, lock-on connection includes circumferentially distributed more than one fixture block 2, and the opposite face of fixture block forms locking face, described
Fixture block relative can gather locking or relative separation unblock.Adapter body includes connection inlet suction port and centre is provided with air inlet and led to
The adapter 15 in road, the housing 19 for being connected to adapter periphery and hollow setting, it is connected with by piston spring 12 on adapter
Vent piston 7, the upper end of vent piston 7 are provided with seal washer 6, are arranged with pushing sleeve 10 outside vent piston 7, and pushing sleeve 10 is by pushing away
The connecting adapter 15 of sleeve spring 11, set is provided with fixture block cover for seat 4 on pushing sleeve, and vent piston 7, pushing sleeve 10 and fixture block cover for seat 4 are equal
It is arranged in housing 19.Housing upper end is provided with end cap set 1, and the upper end inner surface setting of fixture block cover for seat 4 has the first inclined-plane 14, end
Lid 1 upper end inner surface setting of set is the second inclined-plane 9, and the upper and lower ends outer surface of fixture block is arranged to fixture block inclined-plane 13, fixture block inclined-plane
Connection described the first inclined-plane and the second inclined-plane are contradicted respectively, i.e. the inclined-plane of fixture block 2 is connected to described fixture block cover for seat 4 and end cap set
Between 1.
Depression bar 17 is hingedly attached to the housing with, and return unit is provided between depression bar and housing, described depression bar connection push rod 18,
Push rod wears housing connection pushing sleeve 10.
Locking space is formed between vent piston 7 and fixture block 2, inlet channel, vent piston form described venting channels.
