Detailed description of the invention
As shown in Figure 1 and Figure 2, foam gun of the present invention, comprise gun barrel 1, the front end of gun barrel 1 is connected with the rear end of Connection Block joint 2 by threaded portion 1-1, the front end of Connection Block joint 2 is by threaded portion 2-1 connecting ball head Connection Block 3, the rear end of spill plastic spacer 4 connecting ball head 5 is passed through in the front end of bulb Connection Block 3, and the rear end of bulb 5 is sphere 5-1; The front end of bulb 5 connects valve core tube 6 by threaded portion, and the front end of valve core tube 6 connects nozzle 7;
The two ends of valve core tube 6 are formed with internal thread part respectively, and the front end internal thread part of valve core tube 6 matches with the external thread part of nozzle 7, and the rear end internal thread part of valve core tube 6 matches with the nose threads portion of bulb 5;
The nose threads portion 2-1 of Connection Block joint 2 is by packing ring 12 connecting ball head Connection Block 3;
The front end of bulb 5 connects valve core tube 6 by sealing ring 15;
The front end of valve core tube 6 connects nozzle 7 by sealing ring 16;
Spill plastic spacer 4 is fixedly installed in bulb Connection Block 3; As shown in Figure 3, the inner ring of spill plastic spacer 4 forms concave panel 4-1, and the concave shaped face 4-1 of spill plastic spacer 4 matches with the sphere 5-1 of bulb 5 rear end;
The inner chamber of gun barrel 1 is movably set with push rod 8, and the threaded portion 8-1 of push rod 8 front end connects the rear end of Flexible Connector 9, and the front end of Flexible Connector 9 connects the threaded portion 10-1 of spool 10 rear end; Gun barrel 1 is stretched out and connecting valve 11 in the rear end of push rod 8, and switch 11 can drive push rod 8 and spool 10 to move backward;
Spool 10 is successively through bulb Connection Block 3, bulb 5, valve core tube 6, and nozzle 7 is stretched in the front end of spool 10, conflicts on the jet hole of nozzle 7 in the top of spool 10;
The position that spool 10 is positioned at valve core tube 6 is arranged with spring 13, and spring 13 is positioned at valve core tube 6, and spring 13 can provide for spool 10 screen resilience resetted forward;
Spool 10 radially offers a through hole 10-2, is provided with the spacer pin 10-3 matched with it in through hole 10-2; Spacer pin 10-3 is against the front end of spring 13, and spacer pin 10-3 is used for the location of spring 13 front end; Barrier flaps 14 is provided with between spacer pin 10-3 and spring 13 front end; The diameter of barrier flaps 14 is identical with the point diameter of the diameter of spring 13, bulb 5.
Flexible Connector 9 comprises front end connector 9-1, rear end connector 9-2, and front end connector 9-1 and rear end connector 9-2 is connected as one by steel wire 9-3; Front end connector 9-1 and rear end connector 9-2 is formed with internal thread part respectively;
The internal thread part of front end connector 9-1 matches with the threaded portion 10-1 of spool 10 rear end, and the internal thread part of rear end connector 9-2 matches with the threaded portion 8-1 of push rod 8 front end.
Operation principle of the present invention is as follows:
After switch 11 is opened, switch 11 drives push rod 8 to move backward, and push rod 8 is with movable valve plug 10 to pull backward by Flexible Connector 9, under the pressure of spacer pin 10-3, make spring 13 start compression, spool 10 leaves jet hole simultaneously, and now foamed material sprays from jet hole;
If run into the restriction of angle when spraying, valve core tube 6 can be held, relative to valve core tube 6 swivel nozzle 7, thus realizing the adjustment to nozzle 7 angle; Due to the existence of steel wire 9-3 and bulb 5, so the situation that cannot rotate can not be there is; And bulb 5 and bulb Connection Block 3 size match, therefore not rotational valve core pipe 6 time, bulb 5 can not arbitrarily rotate;
After spray coating operations terminates, trip switch 11, under the effect of spring 13 elastic force, spool 10 resets, and again blocks jet hole, now rigid seal occurs, and foamed material cannot spray.
Through simple refit, the present invention can use as air gun.As shown in Figure 4, Figure 5, the rear portion of gun barrel 1 is provided with the upper kettle interface for connecting upper kettle, and the side of upper kettle interface is provided with snap joint 18, and snap joint 18 is connected with external gas source by tracheae; The top of upper kettle interface offers kettle installing port 19, and be movably set with steel ball 19-1 in upper kettle installing port 19, steel ball 19-1 can move upward under gas pressure, is blocked by upper kettle installing port 19.
When not using foamed material to carry out spraying operation, open external gas source, this foam gun can be used as air gun and uses; Due to the existence of steel ball 19-1, after gas enters the inner chamber of gun barrel 1, steel ball 19-1 pushes up, upper kettle installing hole 19 is blocked, therefore the situation of leaking gas can not occur.
As shown in Figure 6, the front end of nozzle 7 can connect auxiliary valve 17.Auxiliary valve 17 is pre-small post-large cone-shaped air tap.When foam gun being used as air gun use, the airflow shaped sprayed from nozzle 7 can be rectified into cylindrical by auxiliary valve 17, makes air-flow have more impulsive force.
As shown in Figure 7, nozzle 7 can connect the front end of valve core tube 6 by multiple spraying nozzle connector 20; Matching with the front end internal thread part of valve core tube 6 in the threaded portion, rear end of spraying nozzle connector 20, is matched by the external thread part of internal thread part with nozzle 7 in the front end of spraying nozzle connector 20.This structure is by assembled connection, and foam gun can be made to carry out bending and rotate, thus change the anglec of rotation, the superposition of multiple bending angle can make the angle of bending increase.
