Description
Technical field
The utility model is related to a kind of technical field of bullet/pill cylinder, specifically related to the sealing knot in a kind of bullet/pill cylinder
Structure.
Background technology
Domestic at present to be used for the caisson of heavy caliber self-propelled gun, casing often faces on the outside of car body when using
The test drenched with rain and paddled, therefore its sealing is particularly important, mainly has following problem during current product use：
(1) bullet/medicine memory cell reaches sealing effectiveness by seal case mostly, once there is local damage, then
All memory cell can all be on the hazard.
(2) bulge sealing adhesive strength is not good enough, and adhering and sealing easily occurs to loosen cracking during use
It is badly in need of developing safer bullet/pill memory cell sealing structure at present.
Utility model content
In view of this, the utility model provides a kind of sealing structure of bullet/pill cylinder, can store single to bullet/pill
First individually sealing, ensures the impulsive force to unit bottom when can bear to load bullet/pill while its sealing.
The sealing structure of a kind of bullet/pill cylinder, it is characterised in that the sealing structure includes closure, rear end cap and interior company
Ring is connect, ancillary equipment is bullet/cartridge case and dividing plate；
The closure outer circumference surface is engaged with the inner peripheral surface of bullet/cartridge case, and sealing cap upper surface is recessed；
The openend of the rear end cap it is horizontally extending go out convex edge for connecting partition；
Stud with threaded hole is machined with the interior connection ring；
Bullet/the cartridge case is connected on dividing plate, and closure openend is downward, closure outer circumference surface and bullet/cartridge case bottom
Inner peripheral surface be adhesively fixed the sealing of bullet/cartridge case, the rear end cap is arranged on bullet/cartridge case bottom, the convex edge of rear end cap and set
Interior connection ring on bullet/cartridge case excircle is bolted to connection in dividing plate both sides, outside the closure recessed portion
Fitted with rear end cap inwall bottom surface.
Further, the depth of the closure recessed portion is more than closure outer circumference surface and bullet/cartridge case inner peripheral surface
The part of bonding.
Further, the closure uses carbon fibre reinforced composite.
Beneficial effect：
1. compared with prior art, the utility model can individually be sealed to bullet/pill memory cell, its sealing is ensured
While easily can be safeguarded and be replaced.
2. the sealing cover structure increase bond area that the utility model is used, ensures adhesive strength.
3. the outer bottom of the utility model closure recessed portion is fitted with rear end cap inwall, what is produced during filling bullet rushes
Hitting power can directly be transferred on rear end cap, and the bonding site of closure does not stress in itself, can ensure the close of adhesive for a long time
Feng Xing.
4. the recessed portion depth of the utility model closure is deeper than the bonding portion of closure and bullet/cartridge case, reserves and apply
The position of daub stick so that bonding is more firm.
5. closure of the present utility model uses carbon fibre reinforced composite, density is the 1/5 of carbon steel, reduces ammunition
Case deadweight not corrosion simultaneously, extends the service life of caisson.
Brief description of the drawings
Fig. 1 is axial arrangement schematic diagram of the present utility model；
Fig. 2 is cross-sectional view of the present utility model.
Wherein, connection ring, 5- dividing plates in 1- bullets/cartridge case, 2- closures, 3- rear end caps, 4-.
Embodiment
With reference to the accompanying drawings and examples, the utility model is described in detail.
The utility model provides a kind of sealing structure of bullet/pill cylinder, and the sealing structure includes closure 2, rear end cap 3
And interior connection ring 4, ancillary equipment is bullet/cartridge case 1 and dividing plate 5；Closure 2 uses carbon fibre reinforced composite.
As shown in Figure 1 and Figure 2, the outer circumference surface of closure 2 is engaged with the inner peripheral surface of bullet/cartridge case 1, the upper surface of closure 2
It is recessed；The openend of rear end cap 3 it is horizontally extending go out convex edge for connecting partition 5；Band spiral shell is machined with interior connection ring 4
The stud of pit；
Bullet/cartridge case 1 is connected on dividing plate 5, and the openend of closure 2 is downward, the outer circumference surface of closure 2 and the bottom of bullet/cartridge case 1
Inner peripheral surface be adhesively fixed and seal bullet/cartridge case 1, rear end cap 3 is arranged on the bottom of bullet/cartridge case 1, the convex edge of rear end cap 3 and set
Interior connection ring 4 on the excircle of bullet/cartridge case 1 is bolted to connection under the both sides of dividing plate 5, bonding closure 2
The outer bottom of recess point is fitted with the inwall of rear end cap 3.
The depth of the recessed portion of closure 2 is more than the outer circumference surface of closure 2 part Nian Jie with the inner peripheral surface of bullet/cartridge case 1,
The position for smearing adhesive is reserved, bullet/cartridge case 1 can be inverted, adhesive is smeared again so that bonding is more firm, passes through
Waterproof test determines its sealing.
When loading bullet/pill, the impulsive force of generation can be directly transferred on rear end cap 3 by the recessed portion of closure 2,
The bonding site of closure 3 does not stress in itself, can ensure the sealing of adhesive for a long time.On bullet/pill bottom and closure 2
Surface is contacted so that be placed exactly in exit at the top of bullet/pill.
In summary, preferred embodiment of the present utility model is these are only, is not intended to limit of the present utility model
Protection domain.It is all it is of the present utility model spirit and principle within, any modification, equivalent substitution and improvements made etc. all should be wrapped
It is contained within protection domain of the present utility model.
