Abstract
The utility model discloses the built-in dismountable draw bar of a kind of gun muzzle, belong to cannon technical field.It is made up of draw bar welding, volution, support plate, block, switch block A processed, switch block B processed and pin, and draw bar welding annulus end has contact with tractor and is directly connected, and journal stirrup end and external two-layer reinforcement cylinder welding form; Outer cylinder rear end is inserted in muzzle brake; Outer cylinder gun muzzle end is processed with screw thread; Support plate plays liner, support limit stop; Block opens chamfering by quadrangular steel sheets both sides, and its front end is welded with a semicircular ring steel plate composition; Block inserts in muzzle brake welds outer cylinder rear end window with draw bar and prevents front and back play; And switch block A, B processed, be stuck in muzzle brake Second Window edge, play preventing side direction play or block from whirlpooling down; Volution is band internal thread annulus, after muzzle brake front and outer cylinder gun muzzle end screwed tight put in place, prevents front and back play; Pin plays the effect preventing from getting loose, sliding.
Description
Technical field
The utility model relates to the built-in dismountable draw bar of a kind of gun muzzle, belongs to cannon technical field.
Background technology
In the prior art, cannon draw bar is all fixed, is generally to adopt tractor and gun carriage afterbody to draw, and draw bar, outside cannon gun muzzle, also has the draw bar be arranged on bottom muzzle brake, and draw bar and cannon are fixed completely; In shooting course, the vibration of gun muzzle is comparatively large, and shooting is sent out after number increases, and cannon draw bar easily produces fatigue crack, when cannon draw, can cause being separated of cannon and tractor, generation major accident.
In order to normally draw when can ensure that cannon is marched, prevent cannon from getting loose, the utility model devises the built-in dismountable draw bar of a kind of gun muzzle, and this draw bar is arranged in gun muzzle when marching, and can dismantle when shooting; When namely avoiding artillery shooting, draw bar is on the impact of barrel and cannon, turn avoid artillery shooting easily produces fatigue crack impact on draw bar; Stability when both having improve artillery shooting and precision, turn improve the reliability of draw bar.
Summary of the invention
The utility model object is to provide a kind of gun muzzle built-in dismountable draw bar, normally draws, prevent cannon from getting loose when this draw bar can ensure that cannon is marched, this draw bar is placed in cannon gun muzzle, possess compact conformation, convenient disassembly, operate light feature.
The utility model solves the technical scheme that its technical problem adopts: the built-in dismountable draw bar of a kind of gun muzzle is made up of draw bar welding, volution, support plate, block, switch block A processed, switch block B processed and pin, draw bar welding is by one end annulus other end journal stirrup, annulus end has contact with tractor and is directly connected, and journal stirrup end and external two-layer reinforcement cylinder welding form; Outer cylinder rear end is inserted in muzzle brake, and its both sides have and muzzle brake Second Window size, window that shape is close, play and support towed gun effect; Outer cylinder front end (gun muzzle end) is processed with screw thread; Support plate is circular steel plate, is welded in windowing place, outer cylinder rear end, plays liner, support limit stop; Block opens chamfering by quadrangular steel sheets both sides, and its front end is welded with a semicircular ring steel plate composition; Switch block A processed, switch block B processed are two triangle steel plates, are welded on the upper and lower two ends, the same side, rear end of block; Block inserts in muzzle brake welds outer cylinder rear end window with draw bar and prevents front and back play; And switch block A, B processed, be stuck in muzzle brake Second Window edge, play preventing side direction play or block from whirlpooling down; Volution is band internal thread annulus, after muzzle brake front and outer cylinder front end (gun muzzle end) screwed tight put in place, prevents front and back play; Pin is made up of spring, latch, is welded on volution, and after volution is tightened and put in place, pin latch inserts volution and outer cylinder endoporus, plays and prevents from getting loose, sliding.
The beneficial effects of the utility model are: normally draw when this draw bar can ensure that cannon is marched, and prevent cannon from getting loose, and are built in cannon gun muzzle, have compact conformation, convenient disassembly, operate light feature.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is A-A sectional view of Fig. 1.
Number in the figure:
1. draw bar welding, 2. volution, 3. support plate, 4. block, 5. switch block A processed, 6. switch block B processed, 7. sell.
Detailed description of the invention
Refer to Fig. 1, the built-in dismountable draw bar of a kind of gun muzzle is made up of draw bar welding 1, volution 2, support plate 3, block 4, switch block A5 processed, switch block B6 processed and pin 7, draw bar welding 1 is by one end annulus other end journal stirrup, annulus end has contact with tractor and is directly connected, and journal stirrup end and external two-layer reinforcement cylinder welding form; Outer cylinder rear end is inserted in muzzle brake, and its both sides have and muzzle brake Second Window size, window that shape is close, play and support towed gun effect; Outer cylinder front end (gun muzzle end) is processed with screw thread; Support plate 3 is circular steel plates, is welded in windowing place, outer cylinder rear end, plays liner, support limit stop 4; Block 4 opens chamfering by quadrangular steel sheets both sides, and its front end is welded with a semicircular ring steel plate composition; Switch block A5 processed, switch block B6 processed are two triangle steel plates, are welded on the upper and lower two ends, the same side, rear end of block 4; Block 4 inserts in muzzle brake welds 1 outer cylinder rear end window with draw bar and prevents front and back play; And switch block A5, B6 processed, be stuck in muzzle brake Second Window edge, play preventing side direction play or block 4 from whirlpooling down; Volution 2 is band internal thread annulus, after muzzle brake front and outer cylinder front end (gun muzzle end) screwed tight put in place, prevents front and back play; Pin 7 is made up of spring, latch, is welded on volution 2, and after volution 2 is tightened and put in place, pin 7 latch inserts volution 2 and outer cylinder endoporus, plays and prevents from getting loose, sliding.
The course of work of the present utility model is: draw bar inserts in muzzle brake, two openings of draw bar welding 1 are alignd with muzzle brake flame jet both sides, the support plate 3 and block 4 that are welded with switch block A5 processed and switch block B6 processed are inserted into muzzle brake and weld space between 1 with draw bar, at gun muzzle end, volution 2 is screwed, make draw bar weld 1 and muzzle brake vibration very close to each other, prevent from loosening with pin 7 locking.
