The specific embodiment
Below in conjunction with accompanying drawing, specific embodiment of the utility model is elaborated.
The utility model comprises nozzle 43, rifle body 1, cavity seat 5, trigger 7 and motor 8, and described cavity seat is arranged on the front portion of described rifle body, and described nozzle is arranged on the front end of cavity seat.In described cavity seat, be provided with cylinder sleeve 5-3, needle 4 can slide in cylinder sleeve.One end of trigger bar 61 is provided with protruding 61-1, and described projection can match with the groove of fork 6 one end.The other end of described fork is also swingingly fixed on cavity seat 5 through the slotted eye on needle 4.The other end of described trigger bar is provided with hole, and matching with the boss that trigger 7 extends in this hole, thereby can make trigger bar and trigger 7 link together.The middle part boss 61-2 of trigger bar is through the bar shape trench hole on motor 8 housings, and on the cylinder between described middle part boss 61-2 and electric machine casing, cover has back-moving spring 62.
Bearing of trend at trigger bar projection 61-1 is provided with slidably quick-release button 63.Described quick-release button comprises a cylinder, at described cylindrical outer surface, be provided with " L " shape groove 63-1, described " L " shape groove can match with the spacing preiection 1-2 on rifle body, to guarantee quick-release button can only slide in its cannelure, can not rotate, and in lateral circumferential groove as long as turn and can not vertically moving.The cylindrical bottom of described quick-release button is also provided with a boss 63-2.The end 63-2 of described quick-release button contacts with the boss 61-2 at trigger bar middle part.On described trigger, be provided with adjusting knob 71, adjusting knob is connected with trigger by screw thread pair.
Above described rifle body, be provided with storage liquid container 2, the liquid outlet 21 of described storage liquid container is connected with described cylinder sleeve 5-3.Container cover 3 is connected with cavity seat by breather line 32.The side that breather line is positioned at container cover is provided with check valve 31.Between container cover and storage liquid container, be provided with sealing ring, between needle and cylinder sleeve, be provided with sealing ring 5-4.The top of rifle body is provided with U-shaped fixture 5-1, and the front end of storage liquid container is fixed by the both sides of described U-shaped fixture.The rearward end of described storage liquid container is provided with catching groove, and the hasp 9 that this catching groove can be provided with rifle body rear end matches.The inner side of described rifle body front end is provided with the track 1-1 of two symmetries, and two outsides of cavity seat are provided with the convex tendon 5-2 matching with described track.The plane that the motor back cover 82 of rifle body afterbody and handle end form is 70 degree with the optimum angle of storage liquid container oral area axis, to guarantee that the feed liquid benefit that spray gun is unlikely to store in liquid container on placing ground or other planes goes out.
When need are installed storage liquid container and cavity seat thereof, the quick-release button 63 being positioned on rifle body is rotated to unlocking condition, then the convex tendon 5-2 on cavity seat outside is aimed to the guide rail 1-1 of rifle body front end inner side, utilize the guide effect of guide rail, one end of cavity seat 5 is advanced to the front end inner side of rifle body 1.When the leading section of fork 6 and an end in contact of trigger bar 61, because one end projection 61-1 of trigger bar is designed to inclined-plane (as shown in Figure 3), under the acting in conjunction of back-moving spring 62, can make the groove of fork 6 leading sections and the protruding 61-1 of trigger bar be fastened togather, rifle body rear end hasp 9 is fastened in the catching groove of storage liquid container rear end simultaneously.Now, storage liquid container and cavity seat thereof install on rifle body.For preventing spray gun generation misoperation, quick-release button rotation 90 can be spent to locking state, the spacing preiection 1-2 on rifle body is entered in the lateral circumferential groove of quick-release button from the cannelure of quick-release button.Now, the boss 63-2 of quick-release button bottom has extended the end side surface of the middle part boss 61-2 of trigger bar, though malfunction trigger 7, but because boss 63-2 limit trigger connecting rod can not move left and right, make it fork and can not drive needle 4 to do corresponding movement, so spray gun cannot be worked.When needing operation, can spend to unlocking condition unloading button opposite spin 90, now the boss 63-2 of quick-release button bottom removes the restriction to trigger bar middle part boss, as long as pull trigger 7, motor is just switched on and is carried out work, air compressing is entered to cavity seat 5 by check valve 10 and entered in storage liquid container by breather line 32, simultaneously by trigger bar 61, drive fork 61 to swing backward, because fork is through the slotted eye on needle 4, thereby valve needle moves backward, the feed liquid that makes to store in liquid container enters in cylinder sleeve by inlet 21, gap ejection from forming between needle and cylinder sleeve again.From the feed liquid of nozzle 43 ejections, mix and atomization with the air-flow spraying from displacement tuyere 41.Displacement tuyere 4 is arranged on the front end of cylinder sleeve 5-3 by nut, rotate displacement tuyere 41 and just can obtain different liquid aerosolization shapes.When spray gun quits work, needle is valve nozzles outlet under the effect of back-moving spring 44.For ease of regulating the size of feed liquid quantity for spray, on trigger, be provided with adjusting knob 71, the displacement of controlling trigger by adjusting knob reaches the displacement of control needle in cylinder sleeve.
If storage liquid container and cavity seat thereof need be disassembled from rifle body, can be by quick-release button rotation to unlocking condition, then press quick-release button 63, just the protruding 61-1 of trigger bar end departs from the engaging of fork 6 leading section grooves, removes rifle body rear end hasp 9 simultaneously and stores engaging of liquid container rear end catching groove.Now, can storage liquid container and cavity seat thereof is separated from rifle body.Operate very convenient.
