State and fourth lane 112 is provided with rifle mouth 111, pin plug 115 is provided with the body of a gun 110, the pin plug 115 is described in
Third channel 114 and the fourth lane 112, and the pin plug 115 blocks the third channel 114.
3rd, fourth lane 112 is horizontally disposed, and third channel 114 aligns with fourth lane 112, both coaxially set
To put, the front end of pin plug 115 is located in fourth lane 112, and to be needle-shaped, the rear end of pin plug 115 is located in third channel 114, and
With type of tamper evidence, the position between third channel 114 and Five-channel 116 can be blocked.
As shown in Figure 1, on the basis of the above embodiment, inclined Five-channel is additionally provided with the body of a gun 110
116 (being not drawn into figure), the first passage 121 are connected with the third channel 114, the both ends point of the Five-channel 116
Do not connected with the third channel 114 and the fourth lane 112, and air-flow passes sequentially through the first passage 121, described
Third channel 114, the Five-channel 116 and the fourth lane 112.
The top of the body of a gun 110 has Five-channel 116, and the rear portion of Five-channel 116 is higher than front portion, and Five-channel 116
Rear portion connected with third channel 114, front end is connected with fourth lane 112, and in the actual course of work, high pressure draught passes through
First passage 121, and after the pressure regulation effect of the pressure regulation plunger 123 in second channel 122, then by flow-rate adjustment plunger
After 210 pressure regulation tune stream, enter in third channel 114, what this hour hands plug 115 was opened, high pressure draught enters Five-channel
116, then enter back into fourth lane 112.
As shown in Figure 1, on the basis of the above embodiment, the adjusting cavity 200 is located at the top of the first passage 121
Hold and the corresponding third channel 114 is set, the opening of the adjusting cavity 200 has internal thread, the flow-rate adjustment plunger 210
Afterbody there is plug 211 and head to be connected with adjusting bolt 212, the adjusting bolt 212 by the internal thread with it is described
The opening of adjusting cavity 200 is spirally connected, and the plug 211 is located at the upside of the first passage 121.
This design, can be such that adjusting bolt 212 is fixed in adjusting cavity 200, so that flow-rate adjustment plunger 210 is fixed
In adjusting cavity 200, also, this design is easy to the air-flow size of adjusting first passage 121.
As shown in Figure 1, on the basis of the above embodiment, the middle part of the adjusting cavity 200 and the first passage 121
Connection, the rear portion of the adjusting cavity 200 are provided with spring 213, and one end of the spring 213 is contradicted in the adjusting cavity 200
On rear wall and the other end is contradicted on the plug 211, and the anterior of the adjusting cavity 200 forms opening with the internal thread
Mouthful.
The design of spring 213, can reset flow-rate adjustment plunger 210；In simple terms, adjusting bolt 212 is exactly turned,
Plug 211 is set constantly to move inward, plug 211 extrudes spring 213 at this time, and when reversely turning bolt, plug 211 is moved out
Dynamic, spring 213 gives the elastic force that plug 211 resets, so that plug 211 can be moved with the movement of adjusting bolt 212.
As shown in Figure 1, on the basis of the above embodiment, trigger 118, the trigger are hinged with the body of a gun 110
118 are connected with the pin plug 115, and the pin plug 115 is pulled when pulling the trigger 118, so that described first is logical
Road 121 is connected with the third channel 114.
Trigger 118 can promote pin plug 115 backward, so that pin plug 115 retreats, such third channel 114 just can be with
Five-channel 116 connects.
As shown in Figure 1, on the basis of the above embodiment, pressure pilot plunger is provided with the Five-channel 116
117, the pressure pilot plunger 117 is used to adjust admission pressure in the Five-channel 116.
What deserves to be explained is, in whole gun body, one shares the component that air pressure or air-flow are adjusted at three, comes from position herein
Say, in the intersection of first passage 121 and second channel 122, pressure regulation plunger 123 plays the role of pressure regulation, first passage 121 it is upper
At end, flow-rate adjustment plunger 210 plays the role of adjusting air-flow and air pressure, and in this design, pressure regulation plunger 123 can play greatly
The effect of amplitude pressure regulation, flow-rate adjustment plunger 210 can play the role of accurately adjusting air-flow air pressure, and pressure pilot plunger
117 in Five-channel 116, can be relatively more steady since high pressure draught is entered in Five-channel 116, so pressure is adjusted
Plunger 117 can play the role of further adjusting air pressure.
As shown in Figure 1, on the basis of the above embodiment, the upper end of the rifle mouth 111 is provided with interface portion 130,
Batch can 140 is connected with the interface portion 130, it is preferred that batch can 140 is arranged on the upper end of rifle mouth 111.
As shown in Fig. 2, on the basis of the above embodiment, the lower end of the rifle mouth 111 is provided with interface portion 130,
Batch can 140 is connected with the interface portion 130, it is preferred that batch can 140 can also be batch can 140, can be located at rifle mouth 111
Lower end.
Specific embodiment described herein is only to spirit explanation for example of the invention.Technology belonging to the present invention is led
The technical staff in domain can do various modifications or additions to described specific embodiment or replace in a similar way
Generation, but without departing from spirit of the invention or beyond the scope of the appended claims.
