Abstract
Integral type firearms piston conduit button hoop, it is a hollow tubular structure that it, which is characterized by it, centre bore is equal to the outer diameter of piston conduit, surface structure: rear portion is the conduit buckle position cooperated with rear sight base, there is bayonet in lower section outside conduit button, front end is the protecting cover back ferrule position cooperated with protecting cover, has card slot in protecting cover back ferrule.The beneficial effects of the utility model are: structure is simple, do not change with the connecting portion structure of component joined together, is provided simultaneously with the function of original two parts；A step reinforcing rib is increased, the rigidity of protecting cover back ferrule is improved；The many and diverse manufacturing procedure of protecting cover back ferrule is eliminated, production efficiency is greatly improved, has saved production cost, while also solving the problems, such as piston conduit button because not firm caused by welding quality.The utility model is suitable for the various firearms based on AK structure.
Description
Technical field
The utility model patent is related to the design of the firearms structure based on AK system.
Background technique
Based on the firearms of AK system, piston conduit as shown in Figure 1, which combines, has the function of piston guide, fixed protecting cover,
Its structure is welded and integral by binding round 13 before piston conduit 14, piston conduit button 11, protecting cover back ferrule 12 and protecting cover.Piston conduit
The major function of button is that piston conduit is fixed on rear sight base, binds round before protecting cover back ferrule and protecting cover and protecting cover is fixed on piston together
On conduit.The piston conduit button and protecting cover back ferrule of the rear end of piston conduit combination at present are two parts, and piston conduit button is casting
Molding, then is machined, and protecting cover back ferrule will be through Multi-step forming and repeatedly heat-treating profiled, then is machined.Pass through between the two
Step surface and circular hole are cooperated, then are fixed together by welding, and are then not connected firmly when welding quality is bad, are easily disengaged, together
When protecting cover back ferrule card slot bottom wall it is relatively thin, poor rigidity.
Summary of the invention
It is strong as caused by not prison welding that utility model aims to solve existing piston conduit buttons and protecting cover back ferrule
The efficiency of degree problem and mechanical stamping processing, providing a kind of can be provided simultaneously with the one of protecting cover back ferrule and piston conduit button function
Body formula piston conduit button hoop.
The technical scheme adopted by the utility model to solve the technical problem is as follows: integral type firearms piston conduit button hoop,
Being characterized by it is a hollow tubular structure, and centre bore is equal to the outer diameter of piston conduit, surface structure: rear portion is and rear sight
There are a bayonet in the conduit buckle position of seat cooperation, the lower section outside conduit button, and front end is the protecting cover back ferrule position cooperated with protecting cover, after protecting cover
There is card slot in hoop.
The utility model is integrated the structure of two parts of former piston conduit button and protecting cover back ferrule, by hot investment casting one
Secondary molding no longer needs to the machining that conformability is carried out to the junction of the two, while without welding, bonding strength is high.
It is connected between protecting cover back ferrule and conduit button by step transition, step is at the back side of card slot.Step is equivalent to reinforcement
Muscle increases card slot bottom wall thickness, improves the rigidity of protecting cover back ferrule.
The beneficial effects of the utility model are: structure is simple, do not change with the connecting portion structure of component joined together, together
When have the functions of original two parts；A reinforcing rib is increased, the rigidity of protecting cover back ferrule is improved；Eliminate protecting cover back ferrule
Many and diverse manufacturing procedure, greatly improves production efficiency, has saved production cost, while also solving piston conduit button because of welding
Not firm problem caused by quality.The utility model is suitable for the various firearms based on AK structure.
Detailed description of the invention
Fig. 1 is conventional piston conduit combination schematic diagram
Fig. 2 is the usage state diagram of the utility model
Fig. 3 is the structural schematic diagram of the utility model
Wherein: 14 piston conduit, 2 one-piece piston conduit button hoop is bound round before 11 piston conduit button, 12 protecting cover back ferrule, 13 protecting cover
21 conduit buckle position, 22 protecting cover back ferrule position 23 step, 24 centre bore, 25 bayonet, 26 card slot.
Specific embodiment
The utility model is described in detail with reference to the accompanying drawing
As shown in Figure 2,3, one-piece piston conduit button hoop 2, it is a hollow tubular structure, and centre bore 24, which is equal to, lives
The outer diameter of conduit is filled in, its surface structure: rear portion is the conduit buckle position 21 cooperated with rear sight base, is buckled with conventional piston conduit
Structure is similar, and there is bayonet 25 in the lower section outside conduit button, for cooperating with rear sight base；Front end is hoop portion after the protecting cover cooperated with protecting cover
There is card slot 26 in position 22 in protecting cover back ferrule, and card slot 26 plays fixed protecting cover, passes through step transition between protecting cover back ferrule and conduit button
Connection, step 23 have the function of reinforcing rib at the back side of card slot 26, increase the rigidity of 26 rear end of card slot.One-piece piston is led
Pipe thread hoop has the function of piston conduit button and protecting cover back ferrule simultaneously, binds round before one-piece piston conduit button hoop and protecting cover and fixes together
In piston conduit outer surface, forms piston conduit and combine.Remaining not described part is same as the prior art.
