Abstract
The utility model discloses a dynamic formula firing mechanism is tied to single shot, hit the needle including rifle bolt and assembly in rifle bolt ladder hole, hit the needle and hit the backshank and hit the syringe needle as an organic whole through hitting the needle pin junction by split type, hit the backshank axial and be equipped with hole, the downthehole main spring that sets up, the rifle bolt also designs to the rifle bolt body of components of a whole that can function independently and rifle bolt head and sells fixed connection through the rifle bolt. This kind split type hits needle and rifle bolt design, thereby is favorable to processing to guarantee assembly quality, reduces the frictional force of hitting needle and rifle bolt, reduces percussion energy loss, simultaneously, the less messenger's striker head of the diameter of striker head is great with the intermural crack of path sector hole of rifle bolt hole, does not influence to hit the needle motion to improve the percussion reliability.
Description
Technical field
This utility model belongs to firearms field, is specifically related to a kind of single-shot bolt dynamic formula firing lock.
Background technology
Single-shot bolt dynamic formula firing lock is a kind of traditional firearms fire design, and its gunlock part-structure includes gunlock body, is provided with ladder endoporus in gunlock body, is provided with firing lock in hole, and gunlock body front end is provided with extractor；Wherein, described firing lock includes stepped cylindrical firing pin and be assemblied in the striker spring of firing pin rear end, and during work, firing pin compresses striker spring backward and loads, and during percussion, firing pin travels forward under striker spring effect and clashes into bullet primers, fires bullet.Wherein during compression striker spring, firing pin entirety will shrink back 5～12, and firing pin is elongate stick-type, difficulty of processing is big, and intensity difference is yielding, firing pin is caused easily to collide and off-energy with gunlock inner hole wall when percussion, percussion sensitivity is low, the most even can cause the phenomenon being difficult to percussion, and firing pin easy fracture.It addition, in existing structure, owing to being step deep hole in gunlock body, little hole depth is relatively big, is difficult to processing.
Utility model content
In order to avoid during percussion, firing pin front end is collided and off-energy with inner hole wall, improve percussion reliability, this utility model provides a kind of single-shot bolt dynamic formula firing lock, firing pin is designed as split type firing pin tail and striker head, firing pin tail and striker head are connected as one by firing pin pin, striker head diameter is less more very much not affects firing pin motion with gunlock endoporus hole wall gap, firing pin tail is relatively large in diameter, it is unlikely to deform and ruptures, firing pin is accurately positioned with gunlock endoporus by the firing pin tail cylindrical being positioned at firing pin rear portion in motor process, guiding firing pin moves, thus avoid firing pin front end hole wall little with gunlock during percussion to collide and cause energy loss, it is difficult to be directed at the defects such as fire in a stove before fuel is added position, improve percussion reliability.
This utility model is achieved through the following technical solutions:
A kind of single-shot bolt dynamic formula firing lock, including gunlock and firing pin, is provided with ladder endoporus, is provided with firing pin in this ladder endoporus in gunlock, described firing pin includes being positioned at the firing pin tail of described gunlock rear end and being positioned at the striker head of described gunlock front end；Described firing pin tail is provided with shoulder hole vertically, the striker spring of percussion force forward is provided to firing pin when in firing pin tail, the big footpath section of shoulder hole is provided with for firing, the suit described striker head of part in the path section of shoulder hole in firing pin tail, described firing pin tail and striker head are fixedly connected as entirety by firing pin pin.
Further, described gunlock includes being positioned at the gunlock body of rear end and being positioned at the handpiece body of front end, and described handpiece body rear end is sleeved in the endoporus of described gunlock body, and gunlock body and gunlock head use gunlock pin to be fixedly connected as entirety.Described small diameter inner hole is positioned at handpiece body, and described larger diameter internal bore is positioned at gunlock body, and larger diameter internal bore is through hole.So, the gunlock being originally used for one is divided into handpiece body and gunlock body two parts, therefore greatly reduces the difficulty of processing of elongated deep hole；The fineness of larger diameter internal bore easily ensures, reduces the frictional force of firing pin and gunlock, reduces firing power loss, thus improves percussion reliability.
Further, the diameter of the firing pin tail on described firing pin is more than the diameter of striker head, and the diameter of striker head is less, and striker head and the path sector hole wall gap of gunlock endoporus that firing pin is anterior are relatively big, do not affect firing pin motion；Firing pin tail is relatively large in diameter, it is unlikely to deform and ruptures, firing pin is accurately positioned with gunlock endoporus by the firing pin tail cylindrical being positioned at firing pin rear portion in motor process, guiding firing pin moves, thus avoid firing pin front end to collide with gunlock endoporus path sector hole wall during percussion and cause energy loss, and be difficult to be directed at the defects such as fire in a stove before fuel is added position, thus improve percussion reliability.
The beneficial effects of the utility model:
Firing pin tail and the striker head of the firing pin design split of single-shot bolt dynamic formula firing lock of the present utility model are connected as one by pin, split type firing pin is designed with beneficially to be processed, the diameter of striker head is less simultaneously, it is that striker head is relatively big with the path sector hole wall gap with gunlock endoporus, does not affect firing pin motion；Firing pin tail is relatively large in diameter, it is unlikely to deform and ruptures, firing pin is accurately positioned with gunlock endoporus by the firing pin tail cylindrical being positioned at firing pin rear portion in motor process, guiding firing pin moves, thus avoid firing pin front end to collide with gunlock endoporus path sector hole wall during percussion and cause energy loss, and be difficult to be directed at the defects such as fire in a stove before fuel is added position, thus improve percussion reliability.Gunlock is also configured as gunlock body and the gunlock head of split, gunlock body and gunlock head simultaneously and is connected by pin fixing, therefore greatly reduce the difficulty of processing of elongated deep hole；It is designed as its fineness of larger diameter internal bore in gunlock body easily to ensure, reduces the frictional force of firing pin and gunlock, reduce firing power loss, thus improve percussion reliability.
