Also include shooting material centre the locking device 124 that gun main body 121 and intermediate transit elbow 123 be locked together;
Intermediate transit elbow 123 includes being shot material the first heel 1231 that the discharge end of gun main body 121 is connected with centre, and The second heel 1232 being connected with middle material sputtering nozzle 122;First heel 1231 includes being shot material the going out of gun main body 121 with centre The connector 123a of material end connection, and the connecting tube 123b being connected with the second heel 1232;Connector 123a is in conical loudspeaker Mouth shape, with annular end face 123a1 and conical inner surface 123a2;Centre shoot material gun main body 121 discharge end be formed with Conical head 1211 and the ring-shaped step 1212 corresponding with annular end face 123a1 that conical inner surface 123a2 matches;
Annular end face 123a1 is formed with multiple positioning convex strip 123a11 arranged in a ring, the horizontal stroke of positioning convex strip 123a11 Section is gradually broadened by tip to root;The end face corresponding with annular end face 123a1 of ring-shaped step 1212 be formed with it is multiple with The strip groove 12121 that each positioning convex strip 123a11 matches;
The surface of conical head 1211 is formed with multiple outer annular burrs 12111 concentric with the axis of conical head 1211, outer shroud The width and height of shape burr 12111 are 0.5-2.5mm, and elastic sealing gasket layer is covered with outer annular burr 12111 12112, conical inner surface 123a2 are formed with multiple annular burr 123a21s concentric with connector 123a axis, inner ring The width and height of shape burr 123a21 are 0.5-2.5mm;
Have between positioning convex strip 123a11 and strip groove 12121 between elastic sealing gasket 12112 compression deformation of layer Gap, when locking device 124 is gradually screwed, outer annular burr 12111 and annular burr 123a21 are to elastic packing bed course 12112 Gradually clamp, closed completely in strip groove 12121 until positioning convex strip 123a11 together with;
Locking device 124 is cylindrical, and one end of inner surface is formed with towards the centre direction of gun main body 121 that shoots material and presses on company The outer surface of joint 123a compresses step 1241, and the other end is formed with internal thread 1242, the side face of ring-shaped step 1212 is formed There is the external screw thread matched with internal thread 1242.In practical work process, the centre rifle 12 that shoots material can utilize moving rail to the present invention Road carries out transverse shifting, and staff's rifle 12 that can be shot material to centre carries out large range of transverse shifting to adapt to mould The position in intermediate feed hole;After locking device 124 are unscrewed, intermediate transit elbow 123 can rely on the company of the first heel 1231 Joint 123a is rotated with the conical head 1211 of the middle discharge end of rifle 12 that shoots material, and makes the specifically alignment shaping of middle material sputtering nozzle 122 The intermediate feed hole of mould, after alignment, can screw locking device 124, make positioning convex strip 123a11 and the correspondence of strip groove 12121 It is fastened togather, it is ensured that intermediate transit elbow 123 is not in the rotation of inhuman wish;After locking device 124 is screwed, taper First 1211 surface and conical inner surface 123a2 mutual cooperations clamp elastic packing bed course 12112 to be carried out on this contact surface Sealing, and annular burr 12111 and annular burr 123a21 can be clamped in both sides to elastic packing bed course 12112 outward, be made The surface of elastic packing bed course 12112 deforms upon mutually embedded outer annular burr 12111 and annular burr 123a21, significantly increases Big area in sealing contact, sealing effectiveness is stronger.
Preferably, the gap between the corresponding positioning convex strip 123a11 of locking device 124 and strip groove 12121 be formed with The through hole 1243 of external world's connection.During locking device 124 is gradually screwed, locking device 124, centre shoots material gun main body Air between 121 and intermediate transit elbow 123 in space can be discharged from through hole 1243, be easy to locking operation.
In order to ensure the validity of the work of through hole 1243 is played, it is preferable that a diameter of 1-2mm of through hole 1243.
Preferably, the cross section of outer annular burr 12111 and annular burr 123a21 is gradually to be become by tip to root Triangle wide, and the tip of the cross section of outer annular burr 12111 and annular burr 123a21 is smooth arc.This structure The depth and closely on outer annular burr 12111 and the surface of annular burr 123a21 insertions elastic packing bed course 12112 can be ensured Property, and the tip of smooth arc will not cause damage to elastic packing bed course 12112.
Preferably, the outer surface of connector 123a compresses the inner surface corresponding section of step 1241 and is connected in cone The outer surface of head 123a matches.While this structure can be such that locking device 124 gradually locks, using with conical inner surface The step 1241 that compresses the automatic alignment result of generation is engaged with the connector 123a with conical external surface, and then make connection The conical inner surface 123a2 evens ground of head 123a compresses elastic packing bed course 12112, will not especially make elastic sealing gasket Layer 12112 produces fold, it is ensured that sealing effectiveness.
Preferably, the lateral surface of connector 123a is more than medial surface and connector 123a with the angle of connector 123a axis The angle of axis, the i.e. inclination angle of connector 123a lateral surfaces is bigger, is compressing step 1241 with connector 123a lateral surface phases In the case of matching somebody with somebody, this structure can make to compress the pressure in the axial direction stronger to connector 123a generations of step 1241, enhancing Compress locking effect.
Preferably, the outer surface of connector 123a is formed with the antifriction bulge loop 123a3 concentric with connector 123a axis, The cross section of antifriction bulge loop 123a3 is the triangle gradually broadened by tip to root, and antifriction bulge loop 123a3's is transversal The tip in face is smooth arc.This structure can make the outer surface of connector 123a pass through antifriction bulge loop 123a3 and compress step 1241 are in contact, and are effectively reduced contact area, so be substantially reduced the outer surface of connector 123a with compress step 1241 it Between frictional force, locking device 124 locking during, greatly reduce locking resistance, easily facilitate locking.Concrete structure can For locking device 124 is equipped with locking positioner (not shown).
Preferably, the inner surface for compressing step 1241 is formed with the antifriction raised line intersected with antifriction bulge loop 123a3 12411.This structure can make the inner surface for compressing step 1241 connect with antifriction bulge loop 123a3 by antifriction raised line 12411 Touch, can further reduce contact area, further reduce connector 123a and compress the frictional force between step 1241.
Preferably, the cross section of antifriction raised line 12411 is the triangle gradually broadened by tip to root, and antifriction The tip of the cross section of raised line 12411 is smooth arc.This structure can make antifriction raised line 12411 and antifriction bulge loop 123a3 Flexible contact, significantly reduces abrasion, it is ensured that the persistence that mechanism uses.
Preferably, antifriction raised line 12411 is perpendicular with antifriction bulge loop 123a3.This structure can reduce single antifriction The contact area of raised line 12411 and antifriction bulge loop 123a3, and then further reduce all antifriction raised lines 12411 and antifriction Wipe the contact area of bulge loop 123a3.
Product form of the invention is not limited to this case diagram and embodiment, and anyone carries out the appropriate of similar thinking to it Change is modified, and all should be regarded as not departing from patent category of the invention.
