Description
Technical field
The present invention relates to a kind of sealing device, particularly a kind of mouth of pipe plug for tightening up formula.
Background technology
With developing rapidly for current automotive industry, the kind of various pipe parts is more and more, is produced and processed at it
Cheng Zhong, is often required for carrying out the water pressure test or air-tight test, such as air inlet pipe, escape pipe, water inlet pipe, drainpipe, and
It is required for line up to be sealed when carrying out these experiments.Conventional sealing device be all it is fixed, i.e., it is precalculated
Particular location of each mouth of pipe in whole fixture on product, then design sealing mechanism in corresponding position.But due to managing at present
The diversity of class part, some shape of products are more complicated, and Existential Space angle between the mouth of pipe, and this allows for jig Design
Certain difficulty all be present with making, even can not be close by the sealing property for influenceing product once fabrication error is slightly larger
Envelope.And to the larger product of those profiles, whole fixture is also mutually in requisition for very greatly, and its cost of manufacture is with regard to of a relatively high.
Mouth of pipe plug is a kind of protection device, in the mouth of pipe for the input house steward for being mainly used in being inserted into air conditioner, with air-conditioning
When the indoor set of device is not connected with outer machine, prevent rainwater, dust etc. from entering in input house steward, play a part of protection input house steward；
And when indoor set is connected with outdoor unit by inputting house steward, mouth of pipe plug is with regard to ineffective.Existing mouth of pipe plug and input house steward
Connected mode mainly have it is following two：One kind is, mouth of pipe plug is in an end closure, the tube-in-tube structure of another end opening, the sleeve
Inside circumference wall be provided with internal thread, the outer circumference wall for inputting the mouth of pipe section of house steward is provided with corresponding external screw thread, connection
When, mouth of pipe plug is screwed onto in the mouth of pipe section of input house steward；Another kind is that mouth of pipe plug is the cylindrical structure of entity, and sets thereon
There is external screw thread, the inside circumference wall for inputting the mouth of pipe section of house steward is provided with corresponding internal thread, and during connection, mouth of pipe plug is threaded into
Input in the mouth of pipe section of house steward.Obviously, the mouth of pipe plug of both the above structure is all to realize to connect with input house steward by screw thread, this
Sample assembly or disassembly is required for firmly tightening, more time-consuming, and the mould structure of screw thread is relatively complicated, expense compared with
It is high.
Such as a kind of pipe mouth sealing plug of Patent No. 201120392320.8, particularly a kind of steel pipe nozzle that is applied to seals
Pipe close.Sealing-plug body outer surface is radially provided with groove, and the sealing being in close contact with internal wall of pipe orifice is equipped with groove
Circle.Pipe close of the present invention is mainly used in the sealing of tubular article, such as steel pipe, the gun barrel mouth of pipe, plays the antirust to inner chamber, prevents
Dirt, protection against the tide, waterproofing protection, so that it is guaranteed that tubular article internal soundness, increases the service life.The pipe close is simple in construction, user
Just, good sealing effect, can repeatedly use, this method is mainly by the change on sealing device structure, improving close
Degree, but sealing effectiveness can not be played completely only by the structures such as groove are added.
A kind of and for example orifice sealing device of Application No. 201210298283.3, including U types deck, clamping screw,
Sealing block；U type decks bottom is provided with the U-lag for being used for blocking product pipe walls, and U-shaped card seat top, which is provided with to be used to install, compresses spiral shell
The mating holes of bar；Clamping screw lower end is connected with the sealing block for the sealed product mouth of pipe.Sealing block bottom is provided with sealed rubber
Mounting groove；Sealed rubber is loaded on sealed rubber mounting groove.Also include a spiral shell being loaded in mating holes for assembling clamping screw
Line sheath；Recoil inserts endoporus is provided with screw rod assembling screw thread, and the contact of flank always has error, and these errors are exactly exactly
Place the problem of gas leakage repeatedly, the device are not suitable for repeatedly regulation, and general once mounting must be used to scrapping, and the later stage is difficult to adjust
Save and re-secure sealing.
The content of the invention
The technical problem to be solved in the invention is to be directed to above-mentioned the deficiencies in the prior art, and a kind of seal degree is provided can
