Description
Technical field
The present invention relates to a kind of sealing device, particularly a kind of mouth of pipe plug tightening up formula.
Background technology
Along with developing rapidly of current automotive industry, the kind of various pipe parts gets more and more, in its process of manufacture, often it is required for carrying out the water pressure test or air-tight test, such as air inlet pipe, escape pipe, water inlet pipe, drain pipe etc., and it is required for line up when carrying out these tests and seals.Conventional sealing device is all fixed, i.e. each mouth of pipe particular location in whole fixture on precalculated product, then designs sealing mechanism in corresponding position.But due to the multiformity of current pipe part, some shape of products are more complicated, and Existential Space angle between the mouth of pipe, this allows for jig Design
All there is certain difficulty with making, once fabrication error is slightly larger, the sealing property affecting product even cannot be sealed.And the product that those profiles are bigger, whole fixture is also in requisition for very big, and its cost of manufacture is just of a relatively high.
Mouth of pipe plug is a kind of protection device, is mainly used in being inserted in the mouth of pipe of the input house steward of air-conditioner, and with when the indoor set of air-conditioner is not connected with outer machine, it is prevented that rainwater, dust etc. enters in input house steward, plays the effect of protection input house steward；And when indoor set and off-premises station connect by inputting house steward, mouth of pipe plug is just ineffective.Existing mouth of pipe plug and the connected mode inputting house steward mainly have following two: Yi Zhongshi, mouth of pipe plug is an end closure, the tube-in-tube structure of other end opening, the inside circumference wall of this sleeve is provided with female thread, the outer circumference wall of the mouth of pipe section of input house steward is provided with corresponding external screw thread, during connection, mouth of pipe plug is screwed onto in the mouth of pipe section of input house steward；Another kind is, mouth of pipe plug is the cylindrical structure of entity, and which is provided with external screw thread, and the inside circumference wall of the mouth of pipe section of input house steward is provided with corresponding female thread, during connection, is threaded into by mouth of pipe plug in the mouth of pipe section of input house steward.Obviously, the mouth of pipe plug of both the above structure is all realize being connected with input house steward by screw thread, and such assembly or disassembly is required for firmly tightening, relatively time-consuming effort, and the mould structure of screw thread is relatively complicated, costly.
Such as a kind of pipe mouth sealing plug that the patent No. is 201120392320.8, particularly a kind of pipe close being applied to steel pipe nozzle sealing.Sealing-plug body outer surface radially has groove, is equipped with and the sealing ring of internal wall of pipe orifice close contact in groove.Pipe close of the present invention is mainly used in tubular article, such as the sealing of the mouth of pipe such as steel pipe, gun barrel, plays antirust, dust-proof, moistureproof, the waterproofing protection to inner chamber, so that it is guaranteed that tubular article internal soundness, increases the service life.This pipe close simple in construction, easy to use, good sealing effect, can repeatedly use, the method is mainly through to the change on sealing device structure, improve compactness, but can not play sealing effectiveness completely only by structures such as adding groove.
And for example application number is a kind of orifice sealing device of 201210298283.3, including U-shaped deck, clamping screw, sealing block；U-shaped deck bottom is provided with the U-lag for blocking product pipe walls, and U-shaped deck top is provided with the mating holes for installing clamping screw；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 one and be loaded in mating holes for assembling the recoil inserts of clamping screw；Recoil inserts endoporus is provided with screw rod assembling screw thread, the contact of flank always has error, and these errors are exactly exactly the problem place repeatedly leaked gas, and this device is not suitable for repeatedly regulating, general once mounting must use scraps, and the later stage is difficult to regulate and re-secure sealing.
Summary of the invention
The technical issues that need to address of the present invention are for above-mentioned the deficiencies in the prior art, and provide a kind of seal degree to control, and formula mouth of pipe plug is tightened up in the fluid injection that can be fastened at any time.
For solving above-mentioned technical problem, the technical solution used in the present invention is:
One tightens up liquid injecting type mouth of pipe plug, including pipe close, described pipe close includes the outer wrapping face of lid and parcel tube wall and interior parcel face, and described lid arranges lift-pull handle, described lift-pull handle one end is vertically hinged with cover edge, and lift-pull handle has rotary tightening device；Described outer wrapping face has around body for penetrating the steel wire passage of steel wire；Described rotary tightening device includes the base being rotatably connected on lift-pull handle, and described base is provided with the fixed station terrace for clamping steel wire and traveling table terrace；Arranging injected rubber hose through described lid, of described injected rubber hose is between outer wrapping face and interior parcel face, and other end has closure cap.
As further preferred version, described traveling table terrace being provided with screwed hole, arranges screw rod through screwed hole, one end of screw rod is radially rotatably connected on fixed station terrace, and described base is additionally provided with the rail plate movable for traveling table terrace.
As further preferred version, described pipe close being provided with at least one lift-pull handle, the quantity of described steel wire passage is corresponding with lift-pull handle quantity.
As further preferred version, described screw rod is provided with swing handle on the one end away from fixed station terrace.
