Description

A kind of air inlet pipe airtight detection inflation inlet combination type plugging structure
Technical field
This utility model relates to a kind of airtight detection articles for use, particularly a kind of airtight detection of air inlet pipe Inflation inlet combination type plugging structure.
Background technology
Its air-tightness in process of production, be detected, it is therefore an objective to prevent by automotive air intake pipe The phenomenons such as part leaks air, and affect service behaviour and safety in utilization.Air-leakage test side Formula is generally divided into two kinds: one is that the closure of all for air inlet pipe mouths of pipe is persistenced an osculum towards air inlet Ventilation in pipe tube chamber, measures leakage rate under barotropic state after stable gas pressure;Another kind be by The all mouths of pipe of air inlet pipe seal a reserved osculum and bleed outwardly, make air inlet pipe tube chamber internal gas pressure exist Leakage rate is measured under negative pressure state.Currently for airtight detecting apparatus inflation inlet (bleeding point) by Being the most all rigid connection in being affected its structure by space mounting limitation etc., easily closure is bad Cause inflation (bleeding) process slow, affect its Detection results.
Utility model content
This utility model is mainly for problem above, it is provided that a kind of compared with similar, has structure Reliably, firmly install, convenient disassembly, good airproof performance, the device of antileakaging advantage, its The technical scheme used is as follows:
A kind of air inlet pipe airtight detection inflation inlet combination type plugging structure includes: top cover, workbench, Shell, base, piston piece, inflation inlet, contour bolt, spring, gas-tpe fitting, O With polyurethane packing ring, described top cover is connected by contour bolt and workbench are fixing, described spring Being set on contour bolt, described workbench is fixedly connected on housing top end, shell bottom and the end Seat is fixing to be connected, and described shell is by workbench and the inner chamber cooperatively forming a closing of base Body, described piston piece is embedded in inner chamber body, and described inflation inlet is embedded on workbench, inflation Mouth connects with piston piece, and gas-tpe fitting is fixedly connected on workbench and connects with piston piece, institute State spring and contour bolt makes block head form floating structure with piston piece coupling part.
On the basis of technique scheme, the part that described shell and piston piece are inlayed all is lined with O Type circle, described base and piston piece contact portion are lined with polyurethane packing ring.
On the basis of technique scheme, described gas-tpe fitting is provided with the structure of engaging button, extraneous Trachea is connected by de-the tearing open of snap-in structure and gas-tpe fitting.
The beneficial effect that this utility model produces has: 1, plugging structure is tied with the connection of piston piece Structure is selected and floating type is flexibly connected, it is to avoid rigid connection easily causes piston piece and damages or draw The drawback of injured labor product;2, plugging structure uses floating structure, in use can be certainly Dynamic(al) correction installation deviation, can make up the impact that deviations brings;3, combination plugging structure Sealing means is consistent with air inlet pipe mounting means essentially with air inlet pipe entrucking mode, makes Closure detection is applied closer to reality;And its plugging effect is more stable reliably makes Detection results more Stable.4, plugging structure can be by adjusting the part 4 internal diameter size with part 5 to adapt to The product caliber of different size in certain limit, its structure tends to standardization, conveniently calls replacing, Reduce the workload of design, be also more conducive to change installation in production engineering.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Symbol description:
1. top cover, 2. workbench, 3. shell, 4. base, 5. piston piece, 6. inflation inlet, 7. Contour bolt, 8. spring, 9. gas-tpe fitting, 10.O type circle, 11. polyurethane packing rings.
Detailed description of the invention
The utility model is described in further detail with example below in conjunction with the accompanying drawings:
As it is shown in figure 1, a kind of air inlet pipe airtight detection inflation inlet combination type plugging structure includes: Top cover 1, workbench 2, shell 3, base 4, piston piece 5, inflation inlet 6, contour bolt 7, spring 8, gas-tpe fitting 9, O 10 and polyurethane packing ring 11, described top cover 1 leads to Crossing that contour bolt 7 and workbench 2 is fixing to be connected, described spring 8 is set on contour bolt 7, Described workbench 2 is fixedly connected on shell 3 top, and shell 3 bottom is fixing with base 4 to be connected Forming cavity, described piston piece 5 is embedded in inner chamber body, and shell 3 and piston piece 5 pass through O Type circle coordinates the cavity closed with base 4 formation, and described inflation inlet 6 is embedded on shell 3, Inflation inlet 6 connects to inflate the corresponding product mouth of pipe or bleeding with piston piece 5 hollow, trachea Joint 9 be fixedly connected on shell 3 and connect with piston piece 5 sidewall, in order to live under pneumatic pressure Plug member 5 action makes it expand the purpose reaching to block the product mouth of pipe with extruding polyurethane packing ring, Described spring 8 and contour bolt 7 make block head form floating junction with external piston piece coupling part Structure.
Preferably, the part that described shell 3 and piston piece 5 are inlayed all is lined with O, institute State base and be lined with polyurethane packing ring with piston piece contact portion.
Preferably, described gas-tpe fitting 9 is provided with the structure of engaging button, and extraneous trachea is by engaging Tear de-with gas-tpe fitting 9 of structure is connected.
This utility model 1, plugging structure and the attachment structure of piston piece select floating type flexibility even Connect, it is to avoid rigid connection easily causes the drawback that piston piece damages or scratches product;2、 Plugging structure uses floating structure, in use can be from dynamic(al) correction installation deviation, can To make up the impact that deviations brings;3, combination plugging structure sealing means fills with air inlet pipe Car mode is consistent with air inlet pipe mounting means essentially, makes closure detect closer to reality Application;And its plugging effect is more stable reliably makes Detection results more stable.4, plugging structure Can be by adjusting the internal diameter size of part 4 and part 5 to adapt to different size in certain limit Product caliber, its structure tends to standardization, conveniently calls replacing, reduces the work of design Amount, is also more conducive to change installation in production engineering.
The most by way of example this utility model is illustrated, but this utility model is not limited to Above-mentioned specific embodiment, all any changes done based on this utility model or modification belong to this The scope that utility model is claimed.
