The specific embodiment

Among Fig. 1, the utility model comprises glue rifle body 1, is fixed in the glue small of the stock 12 of glue rifle body 1 through clip 16; Be provided with in the glue small of the stock 12 with trigger 24 and cooperate to control the valve train of gas break-make; The glue small of the stock 12 bottoms are provided with the fast joint 14 that is used to insert external air source; Fast joint 14 links to each other with the air inlet of valve train.

Glue rifle body 1 front end is provided with drive end bearing bracket 4, and the rear end is provided with rear end cap 3; The gas outlet of valve train links to each other with bent sub 15 on the rear end cap 3 through tracheae 26, and external air source is imported glue rifle body 1 inner chamber.

Be provided with the spacing ring 7 that is used for limited piston cavity 6 displacements in the glue rifle body 1; Glue rifle body 1 is connected through being rolled into interference fit (sealing) with spacing ring 7.Glue rifle body 1 inner chamber is divided into through spacing ring 7 and is used to place the anterior gel region of hard tube 10 and the rifle core district, rear portion that is used to hold the rifle core; Hard tube 10 is installed between spacing ring 7 and the drive end bearing bracket 4; Hard tube 10 front ends are provided with glue discharging mouth 25.

Hard tube 10 is filled with the bought-in article of colloid in being, hard tube 10 rear ends are provided with glue lid 13.

Glue rifle body 1 inner chamber is provided with the rifle core that is used to promote colloid in the hard tube 10; Said rifle core comprises piston cavity 6, piston rod 5.Can be connected (outer gland 8 is used for auxiliary guiding) with glue rifle body 1 matched in clearance through the outer gland 8 that is fixed in piston cavity 6 afterbodys along the piston cavity 6 that glue rifle body 1 inner chamber slides.Outer gland 8 and piston cavity 6 rear ends are through being threaded.The rear end of the piston rod 5 that can slide along piston cavity 6 inner chambers places in the piston cavity 6, is tightly connected through internal gland 9 and piston cavity 6.Internal gland 9 is connected through thread seal with piston rod 5 rear ends.Piston rod 5 front ends are equipped with the top 2 that is used to promote glue lid 13 in the hard tube 10.

Piston cavity 6 front ends are provided with and are used for positioning piston bar 5 and prevent that piston rod 5 tail ends break away from the spacing gland 11 of piston cavity 6.

The basic functional principle of the utility model is: outside constant source of the gas (0.4MP) gets into the glue small of the stock 12 through fast joint 14; Gas gets into glue rifle body 1 inner chamber of sealing through tracheae 26 to bent sub 15 under the control of valve train (spool 17, valve body 18, spool A19, sealing ring A20, sealing ring B21, spool B22, valve gap 23): because the entering of gas; Add the sealing of upper end cover 3 and glue rifle body 1; The sealing of spacing ring 7 and glue rifle body 1, the sealing of internal gland 9 and piston cavity 6, gas promotes piston cavity 6, piston rod 5 etc. and moves forward together; Thereby promote the lid of the glue in the hard tube 10 13, the glue in the hard tube 10 is got out through glue discharging mouth 25.It is out of service when piston cavity 6 moves to certain position in this process owing to the restriction of spacing ring 7; At this moment gland 9 receives the effect that is slightly less than original power with rifle body 5 and continues to promote glue lid 13 motions in the hard tube 10, and glue has been beaten and perhaps received the restriction of spacing gland 11 and stop in hard tube 10.In this whole process of playing glue, if want that interrupting playing glue can decontrol trigger 24, because the control of valve train, fast-discharge valve is exitted fast, thereby glue is played in interruption fast.When following glue is changed, turn on drive end bearing bracket 4, take out the hard tube 10 of having played glue, change when propping up, promote top 2 with the hard tube of changing 10 and make the rifle core get back to original position, tighten drive end bearing bracket 4.

The utility model rifle core adopts the folding cylinder of two joints, can adopt three joints or above folding cylinder, further shortens the coating gun structure.Adopt two joint structures, the cylinder diameter difference is smaller, and not occurring pressure in actual use has bigger variation, and gluing also relatively evenly.

Among Fig. 2, valve train is a prior art, and the most handy two pass air valve if use the single track air valve, need add fast-discharge valve.Valve train comprises spool 17, valve body 18, spool A19, sealing ring A20, sealing ring B21, spool B22, valve gap 23.The operation principle of valve train is: after manually cocking 24 puts in place; Spool B22 conehead contacts with spool A19 sealing; Block spool A19 endoporus air flue, open the air flue of spool A19 and sealing ring B21 then, gases at high pressure are in fast joint gets into the glue small of the stock 12; Get into the glue small of the stock 12 ventholes through the circular hole on spool A19 endoporus and its external diameter again, get into rifle in-core portion through tracheae then; When closing gas circuit; Manually unclamp trigger 24, each valve core reset under the effect of spring 30, spool A19 and sealing ring B21 close; Spool B22 conehead and spool A19 open owing to glue rifle body pressure inside immediately; The gases at high pressure that quick drain glue rifle body is inner, when manually pushing back the rifle core, rifle in-core portion gas is also from getting rid of here simultaneously.
