Abstract
The utility model discloses an air gun with a replaceable gun barrel, which aims to solve the problems of an irreplaceable gun barrel, inapplicability to bullets with different sizes and inconvenient use of an existing air gun. The air gun with a replaceable gun barrel comprises the gun barrel and flat iron; a cavity matching with the gun barrel in shape is arranged on the upper portion of the flat iron; the gun barrel is mounted inside the cavity and in clearance fit with the flat iron; and a set screw for fixing the gun barrel is further arranged on the flat iron. The air gun can facilitate replacing the gun barrel, and is applicable to the bullets with different sizes and convenient in use.
Description
Technical field
The utility model relates to a kind of air gun, particularly a kind of air gun of interchangeable barrel.
Background technology
Air gun is a kind of low-power rifle that relies on compressed air to launch little metal bullet, existing air gun, be the monoblock type air gun, the gun barrel of air gun press-fits on band iron, and gun barrel and band iron form interference fit, and gun barrel can't be changed, therefore can't be suitable for the bullet of different sizes, when changing different big pellet, need to change gun, use inconvenient.
Chinese patent notification number CN2061268U, the August 29 nineteen ninety day for announcing, announced a kind of short type air gun, this air gun mainly is made up of members such as gun barrel, piston, sleeve, trigger, sears, gun barrel fixedly is loaded in the sleeve, is interference fit between gun barrel and the sleeve, and gun barrel can't be changed, can't be suitable for the bullet of different sizes, use inconvenient.
Summary of the invention
The purpose of this utility model is to have now air gun can't change gun barrel, can not be suitable for the bullets of different sizes, and inconvenient problem with use provides a kind of conveniently replaced gun barrel, the bullets of applicable different sizes, the air gun of interchangeable barrel easy to use.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of air gun of interchangeable barrel, comprise gun barrel and band iron, described band iron top is provided with the cavity that shape and gun barrel match, gun barrel is loaded in the cavity, gun barrel and band iron form matched in clearance, also are provided with the fixedly holding screw of gun barrel on the band iron.The cavity on band iron top is used to adorn gun barrel, original air gun gun barrel and band iron form interference fit, gun barrel can't be changed, can't be suitable for the bullet of different sizes, after the improvement, gun barrel and band iron form matched in clearance, and with the fixing gun barrel of holding screw, gun barrel easy accessibility like this, in the face of the bullet of different sizes the time, the gun barrel of replaceable different bores.
As preferably, described cavity is made up of former and later two coaxial cylindrical bore, and the external diameter of preceding cylindrical bore is greater than the external diameter of back cylindrical bore, and forward and backward cylindrical bore internal diameter is identical.Preceding cylindrical bore is positioned at the front end of band iron cavity, and back cylindrical bore is positioned at the rear end of band iron cavity, and forward and backward cylindrical bore is coaxial and internal diameter is identical.
As preferably, the bottom of band iron front end has set screw hole, cylindrical bore before set screw hole is communicated with, and the bottom of gun barrel outer wall is provided with the groove that docks with set screw hole, holding screw is loaded in the set screw hole, and the front end of holding screw is positioned at the groove of gun barrel outer wall.Set screw hole is used to install holding screw, and holding screw connects band iron and gun barrel, thereby gun barrel is fixed; Holding screw is located at fixedly gun barrel of band iron front end, cooperates the gun tube rear end that is loaded in the cylindrical bore of back, and it is stable that the gun barrel fixation is set like this.
As preferably, the front end of holding screw is taper, the taper of the groove of gun barrel outer wall for matching with holding screw front end shape.The front end and the groove of holding screw are arranged to taper, easy accessibility.
The beneficial effects of the utility model are: gun barrel and band iron form matched in clearance, and the fixedly holding screw of gun barrel is set on the band iron, and conveniently replaced gun barrel is suitable for different big or small bullets, and is easy to use.
Description of drawings
Fig. 1 is a kind of main TV structure schematic diagram of the present utility model.
Among the figure: 1, gun barrel, 2, band iron, 3, holding screw.
The specific embodiment
Below by specific embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment:
A kind of air gun of interchangeable barrel (referring to accompanying drawing 1), comprise gun barrel 1 and band iron 2, the main body of gun barrel 1 is a round steel pipe, the right-hand member of gun barrel 1 is the shoot pipe of one section external diameter less than gun barrel 1 main body round steel pipe, the internal diameter that shoots pipe is identical with the internal diameter of gun barrel 1 main body round steel pipe, the top of band iron 2 has the cavity that runs through band iron about 2 ends, gun barrel 1 is loaded in the cavity, gun barrel 1 forms matched in clearance with band iron 2, the gap is 0.2 millimeter, cavity comprises the preceding cylindrical bore in left side and the back cylindrical bore on right side, preceding cylindrical bore and back cylindrical bore are coaxial, the internal diameter of preceding cylindrical bore is identical with the internal diameter of back cylindrical bore, the external diameter of preceding cylindrical bore is greater than the external diameter of back cylindrical bore, the pipe that shoots of gun barrel 1 right-hand member is positioned at the back cylindrical bore, the part of the main body round steel pipe of gun barrel 1 is positioned at preceding cylindrical bore, the bottom of band iron 2 left ends has the set screw hole of vertical direction, cylindrical bore before the upper end of set screw hole is communicated with, the bottom of the main body round steel pipe outer surface of the gun barrel 1 of cylindrical bore has the groove of taper before being positioned at, the groove of taper docks with set screw hole, the upper end screws in the set screw hole for the holding screw 3 of taper, the tapered end of holding screw 3 stretches in the conical socket of gun barrel 1 outer surface, thereby gun barrel 1 is fixing.
When using the bullet of different sizes, only need pull down holding screw 3, in the cavity of band iron 2, extract gun barrel 1 again, select the suitable gun barrel 1 of bore, in the cavity of the band iron 2 of again it being packed into, screw on holding screw 3, once more that gun barrel 1 is fixing, it is convenient that gun barrel 1 is changed, the bullet of applicable different sizes.
Above-described embodiment is a kind of preferable scheme of the present utility model, is not that the utility model is done any pro forma restriction, also has other variant and remodeling under the prerequisite that does not exceed the technical scheme that claim puts down in writing.
