Abstract
The utility model discloses a gun-barrel changeable air gun, which comprises a gun barrel and a node sleeve, wherein a conical hole is arranged on the gun barrel, the corresponding position of the node sleeve is provided with a threaded hole, a screw is fixedly connected with the gun barrel through the threaded hole on the node sleeve. The tail end of the gun barrel is a step cylinder shape, a nest is arranged in the node sleeve, and the tail end of the gun barrel is arranged in the nest. The gun-barrel changeable air gun adopts a plug-pull-type and screw fixing structure, thereby having simple structure, safe and convenient gun barrel changing and low cost. An air gun can be led to have two functions of 4.5mm and 5.5mm calibers through changing gun barrels on the same air gun.
Description
Affiliated technical field:
The utility model relates to air gun, particularly adopts the air gun of interchangeable gun barrel.
Background technology:
Air gun only disposes a gun barrel at present, and gun barrel overlaps the structure that adopts one with joint.The bore of air gun has 2 kinds of specifications, is two kinds of 4.5mm and 5.5mm, and two kinds of different bores belong to dissimilar air guns, have different functions, and these functions will be used two rifles, the cost height if desired.
Summary of the invention:
The purpose of this utility model provides the air gun of interchangeable gun barrel.
The utility model comprises gun barrel and joint cover, is provided with taper hole on gun barrel, is provided with screw on the correspondence position of joint cover, and the screw that screw puts by joint is fixedlyed connected with gun barrel.
The tail end of gun barrel is that step is cylindrical, is provided with nestedly in the joint cover, and the tail end of gun barrel is positioned at nested.
Owing to adopt the fixing structure of plug-in and screw, make simple in structure, change the gun barrel safe ready, cost is low.Can on an air gun, realize that by changing gun barrel an air gun can have 4.5mm and two kinds of functions of 5.5mm bore by this structure.
Description of drawings:
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is the longitudinal section schematic diagram of the utility model gun barrel user mode;
Fig. 2 is the longitudinal section schematic diagram of the utility model gun barrel released state.
1. gun barrel 2 screws 3 joint covers 4 nested 5 are located axle sleeve 6 sealing rings
The specific embodiment:
From Fig. 1 and Fig. 2 as can be seen, on gun barrel (1), be provided with taper hole, on the correspondence position of joint cover (3), be provided with screw, and the screw (2) that has the conical surface is housed in this screw, after packing joint cover (3) into, passes through gun barrel lock-screw (2), just can limit the free degree that gun barrel (1) moves forward and backward, also can limit the free degree that gun barrel (1) rotates around longitudinal axis, thereby reach the fixedly purpose of gun barrel.
As can be seen from Figure 1, the tail end of gun barrel (1) adopts cylinder to cooperate with cooperating of joint cover (3), and high-grade fit tolerance is adopted in its cooperation, cooperates the precision that can guarantee that gun barrel is fixing closely.
As can be seen, gun barrel (1) is processed into the step circle, and is provided with nested (4) in joint cover (3) from Fig. 1 and Fig. 2, can be so that when inserting, gun barrel do not interfere with location axle sleeve (5), and nested (4) have also played the function of fixed seal ring (6).
It can also be seen that from Fig. 1 location axle sleeve (5) is positioned at below nested (4), intersect vertically, and embed nested (4) with nested (4).Location axle sleeve (5) has played the effect of fixing nested (4).
As can be seen from Figure 2, just gun barrel can be extracted from joint cover (3), thereby can be replaced with the gun barrel of another bore when unclamping screw (2).
Claims (3)
1. the air gun of interchangeable gun barrel comprises gun barrel and joint cover, it is characterized in that being provided with on gun barrel taper hole, is provided with screw on the correspondence position of joint cover, and the screw that screw puts by joint is fixedlyed connected with gun barrel.
2. the air gun of interchangeable gun barrel according to claim 1, the tail end that it is characterized in that described gun barrel is that step is cylindrical, is provided with nestedly in the joint cover, the tail end of gun barrel is positioned at nested.
3. the air gun of interchangeable gun barrel according to claim 2, it is characterized in that locating axle sleeve be positioned at described nested below, intersect vertically with nested, and embed nested.
