Description

Pneumatic stapler

The utility model relates to a kind of pneumatic tool of architectural decoration, particularly a kind of pneumatic stapler.

Existing pneumatic stapler generally is made up of rifle body, cylinder piston member, inlet channel, exhaust passage and pneumatic valve control device, its pneumatic operated valve controlling organization operated by rotary motion is at the top of cylinder, and the exhaust passage also is arranged on two ones of pneumatic operated valve controlling organization.The ail gun of this structure exists following deficiency:

1. because except that noise is big, also arrange the greasy dirt air to working substance easily in exhaust the place ahead on the rifle body, pollute working substance, influenced the attractive in appearance of ornament, increased labor intensity of operating personnel;

2. the complex structure of pneumatic control valve, make and assembling very inconvenient, and be difficult for guaranteeing the service precision requirement;

3. because the regular use of the striker on the ail gun, and striker is damaged easily, when maintenance or replacing striker, must be all after the dismounting with the top cover at ail gun top and pneumatic control valve, can carry out the replacing of striker, when bringing very big inconvenience to maintenance, the user also is difficult for guaranteeing reseting precision.

The purpose of this utility model just provides a kind of simple in structure, easily manufactured and pneumatic stapler that noise is little, and it can avoid polluting working substance, when guaranteeing the product precision, easily the striker of ail gun is changed.

The purpose of this utility model is to realize by such technical scheme, it includes the rifle body, the cylinder piston member, inlet channel, exhaust passage and pneumatic valve control device, it is characterized in that: the pneumatic operated valve controlling organization is to be respectively arranged with pneumatic valve pocket and manual valve pocket in rifle body inside cylinder one side, be provided with in the pneumatic valve pocket respectively and inlet channel, the exhaust passage, cylinder intake Tan, the air admission hole that manual valve pocket communicates, the exhaust annular groove, airway, air intake duct, manually valve pocket communicates with inlet channel by the thin passage of air inlet, being provided with in the pneumatic valve pocket can axially movable balanced valve, be with the valve pocket that is connected with the pneumatic operated valve cavity wall on the balanced valve, the hole that is arranged on valve pocket communicates with the exhaust annular groove, manually be provided with valve nozzle in the valve pocket, manual valve pocket and corresponding with plate machine handle is passed in the valve nozzle bottom.

Owing to adopted technique scheme, the utlity model has following advantage:

1. manufacturing simple in structure, pneumatic control valve is easy to assembly easily, guarantees the service precision of product;

2. adopt afterbody noise reduction exhaust, noise is little, avoids greasy dirt gas row to working substance;

3. pneumatic control valve adopts the balanced valve of flexibility and reliability, and the admission pressure loss is little, and exhaust back pressure is little;

4. air cylinder head structure is simple, needn't dismantle the pneumatic operated valve member, need only open top cover, just can change easily striker, and can guarantee that the precision of product is not destroyed.

Description of drawings of the present utility model is as follows:

Fig. 1 is a structural representation of the present utility model;

Work reference diagram when Fig. 2 is the utility model air inlet;

Work reference diagram when Fig. 3 is the utility model exhaust.

Among the figure: 1. rifle body; 2. cylinder piston member; 3. inlet channel; 4. exhaust passage; 5. pneumatic valve pocket; 6. manual valve pocket; 7. cylinder intake Tan; 8. air admission hole; 9. exhaust annular groove; 10. the thin passage of air inlet; 11. balanced valve; 12. valve pocket; 13. hole; 14. valve nozzle; 15. plate machine handle; 16. noise reduction plug; 17. sealing ring; 18. cushion rubber; 19. cylinder return-air Tan; 20. airway; 21. air intake duct;

The utility model is described in further detail below in conjunction with drawings and Examples:

As shown in Figure 1, the utility model includes rifle body 1, cylinder piston member 2, inlet channel 3, exhaust passage 4 and pneumatic valve control device, it is characterized in that: the pneumatic operated valve controlling organization is to be respectively arranged with pneumatic valve pocket 5 and manual valve pocket 6 in rifle body 1 inside cylinder one side, be provided with in the pneumatic valve pocket 5 respectively and inlet channel 3, exhaust passage 4, cylinder intake Tan 7, the air admission hole 8 that manual valve pocket 6 communicates, exhaust annular groove 9, airway 20, air intake duct 21, manually valve pocket 6 communicates with inlet channel 3 by the thin path 10 of air inlet, being provided with in the pneumatic valve pocket 5 can axially movable balanced valve 11, be with the valve pocket 12 that is connected with pneumatic valve pocket 5 inwalls on the balanced valve 11, the hole 13 that is arranged on valve pocket 12 communicates with exhaust annular groove 9, manually be provided with valve nozzle 14 in the valve pocket 6, manual valve pocket 6 and corresponding with plate machine handle 15 is passed in valve nozzle 14 bottoms.

Operation principle of the present utility model is such: as shown in Figure 1, 2, when pulling plate machine handle 15, plate machine handle 15 promotes valve nozzle 14 and blocks the thin path 10 of air inlet, gases at high pressure promote balanced valve 11 to move down from inlet channel 3, air admission hole 8, make balanced valve 11 with hole 13 sealings, cylinder intake Tan 7 is isolated with exhaust passage 4 and does not communicate, gases at high pressure enter cylinder intake Tan 7 through air admission hole 8, pneumatic valve pocket 5, airway 20, thereby the piston in the promotion cylinder is done to impact moving downwards, finishes the purpose of nailing.As Fig. 1, shown in 3, when not pulling plate machine handle 15, valve nozzle 14 is not blocked the thin path 10 of air inlet, from the gases at high pressure of inlet channel 3 through the thin path 10 of air inlet, manual valve pocket 6, air intake duct 21 enters the bottom of pneumatic valve pocket 5, because the pressure in the gases at high pressure equates, the area at balanced valve 11 tops is less, the area of bottom is bigger, form then that balanced valve 11 is upwarded pressure is poor, balanced valve 11 moves up and blocks air admission hole 8, gases at high pressure in the return-air Tan 19 enter lower chamber of air cylinder promotion piston and upwards do to reset motion, at this moment, hole 13 is open-minded, and the gas in the cylinder intake Tan 7 can be through airway 20, pneumatic valve pocket 5, hole 13, exhaust annular groove 9, it is external that rifle is discharged in exhaust passage 4.

As shown in Figure 1, the noise that produces when reducing exhaust, exhaust passage 4 is provided with noise reduction plug 16.

As shown in Figure 1, in order to reach the sealing function of 13 pairs of air admission holes of balanced valve, balanced valve 11 tops are provided with sealing ring 17.

As shown in Figure 1, be isolated with cylinder intake Tan 7 in order to guarantee 13 pairs of holes of balanced valve, exhaust annular groove 9 and exhaust passage 4, balanced valve 11 middle parts are provided with the cushion rubber 18 that matches and seal with valve pocket 12 inwalls.

As shown in Figure 1, for fear of greasy dirt gaseous contamination working substance, the gas outlet of exhaust passage 4 is arranged on the afterbody of rifle body 1.
