Description
Technical field
The utility model relates to a kind of sealing frock that is used for aircraft pressure cabin, wing tank and hull, particularly a kind of non-seal pouring instrument of opening wide district's seepage calking.
Background technology
Good sealing structure is the key that guarantees the product serviceability.Seal form commonly used has: sealing in the seam (being coated with encapsulant between two and plural part), seam external seal (peripheral edge in structure is coated with encapsulant), securing member sealing (being coated on the connector with encapsulant).But in actual production, product leaks air, the phenomenon of leakage of oil (or leaking) is inevitable.Usually the method for getting rid of seepage is the use amount that increases the seepage place encapsulant, promptly is coated with in the outside that the seepage zone occurs to add encapsulant again; Another kind method is to decompose constitutional detail that seepage occurs, just the product that assembles is disassembled, and removes original encapsulant, applies syndeton part behind the encapsulant again.Existing repair method exists the increase construction weight, influences the outward appearance of product, and the reclamation work amount is big, easily produces the problem of secondary fault.
Summary of the invention
The purpose of this utility model is to provide a kind of seal pouring instrument, is used to reach fast and effeciently get rid of seepage and some non-districts that open wide are sealed calking.
For reaching above purpose, the utility model takes following technical scheme to be achieved:
A kind of seal pouring instrument, it is characterized in that, comprise a screw rod that can penetrate in the product sandwich hole, this screw head diameter is greater than screw diameter, screw head is connected with pneumatic colloid-injecting gun or special-purpose injecting glue equipment injected rubber hose, the bar tail is connected with clamping sleeve, be provided with sealing ring between the head of clamping sleeve and screw rod and block two ends, product sandwich hole respectively, penetrate the hollow structure of screw rod in the product sandwich hole for being communicated with injected rubber hose, bar wall upper edge screw axial is established plurality of rows injecting glue through hole, fluid sealant by injected rubber hose by screw head and body of rod cavity, the injecting glue through hole injects the cavity in product interlayer slit.
In the such scheme, described screw head is provided with internal thread, and the injected rubber hose of pneumatic colloid-injecting gun or special-purpose injecting glue equipment is connected with the internal thread of screw head by the external screw thread of the mouth of pipe, and the screw head profile is 100 ° and immerses oneself in to design.Described injecting glue through hole is provided with 1-4 row along screw axial; Every row's injecting glue through hole is along bar wall radial equipartition 3-6.Described bar tail is threaded with being connected to of nut with locking.
Use the beneficial effect of sealing injecting glue instrument to be, only need be connected securing member with the position partial dismantling that cavity is arranged to seepage occurring, the seal pouring instrument is installed, utilize the pressure of colloid-injecting gun encapsulant to be added in the cavity that seepage occurs, to reach quick eliminating seepage and to realize partially sealed purpose.Avoided workload that detaching structure spare causes to increase and decomposable process in the new fault that produces even may cause scrapping of product.
Description of drawings
Fig. 1 is the structural representation of the utility model seal pouring instrument.
Number description: 1. nut, 2. clamping sleeve, 3. screw rod, 4. sealing ring (2), 5. injecting glue through hole, 6. product interlayer.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As shown in Figure 1, a kind of seal pouring instrument, the head configuration of screw rod 3 is 100 ° immerses oneself in to design, can satisfy the head type have smooth outer rim to require selected securing member at present, and head 1/8 " the BSP internal thread is designed for pneumatic colloid-injecting gun (or special-purpose injecting glue equipment) injected rubber hose interface external thread and is connected; The body of rod adopts the cavity design, and presses product interlayer 6 thickness different sizes on the bar wall and arrange 1-4 row injecting glue through hole 5, also can increase row's design according to thickness of interlayer.Fluid sealant passes through the head of screw rod and the interlayer slit that body of rod cavity, injecting glue through hole 5 inject products by colloid-injecting gun; The external screw thread of bar tail is connected with nut 1.Sealing ring 4 adopts rubber ring, is used to block the two ends in product sandwich hole, and its effect is to guarantee that fluid sealant has enough pressure to get into the cavity in product interlayer slit, reaches the product seal request.Clamping sleeve 2 shields to product surface simultaneously.The diameter of screw rod 3 and length depend on original fastener apertures of hermetically-sealed construction and thickness of interlayer, and the diameter of screw rod should be less than the structure aperture of product interlayer 6.The gum-injecting port external screw thread of colloid-injecting gun should be complementary with the screw head internal thread.
Using method of the present utility model is as follows: decompose the securing member of revealing the portioned product interlayer, record original fastener apertures and thickness of interlayer, select the injecting glue instrument (making series) that is suitable for.With the colloid-injecting gun gum-injecting port 1/8 " the BSP external screw thread is connected and tightens (colloid-injecting gun is not connected with wind regime earlier) with the screw rod 3 head internal threads of injecting glue instrument; screw rod 3 is inserted in the hole in analytical product sandwich hole; and assurance product upper and lower surface has been installed sealing ring 4; clamping sleeve 2 and nut 1 are installed then, are screwed up with a wrench.Connect source of the gas, pull the colloid-injecting gun trigger, fluid sealant is pressed into cavity between the product interlayer by air pressure.Decompose nut 1 and clamping sleeve 2, take off sealing ring 4, extract screw rod 3, securing member is installed.Getting rid of the work of seepage has just fast and effeciently been finished.If the bleed pressure deficiency of factory building, colloid-injecting gun can be connected with booster pump.
Do not open wide the calking injecting glue at position for those, its method of operating only need change the injected rubber hose of colloid-injecting gun into the flexible pipe form and get final product with above-mentioned consistent.
Seal pouring instrument of the present utility model has been realized fast and effeciently getting rid of seepage and some non-opening wide has been distinguished the purpose that seals calking.
