For guaranteeing the normal discharging of paint, between the suction tube in paint spray gun bucket and the material-pumping tube outside cover, must guarantee effective tightness.
At present, existing suction tube is generally that the mode that is connected by direct welding or splicing is positioned at and under cover, realizes and being tightly connected of material-pumping tube, this structure arranges the defect that existence is very large, cause the relative cover of suction tube to dismantle on the one hand, this useless paint after using to batch can cleans and brings very big inconvenience, the rotation adjustment that cannot carry out suction tube on the other hand, because suction tube itself is exactly a bending tube, its installation has directivity, if installed, depart from, will cause the paint vehicle in batch can cannot extract out completely and cause a large amount of residues, cause unnecessary waste.
Model utility content
For the problems referred to above, the utility model has designed a kind of material-pumping tube and suction tube Hermetical connecting structure of paint spray gun bucket, suction tube is wherein realized and being tightly connected by a quick-acting joint and material-pumping tube, has good sealing effect, convenient disassembly, and can freely adjust the feature of angle.
For achieving the above object, the utility model is by the following technical solutions:
A kind of material-pumping tube of paint spray gun bucket and suction tube Hermetical connecting structure, comprise cover, material-pumping tube and suction tube, it is characterized in that: the afterbody of described material-pumping tube forms a junction through a whole cover test part, joint outer wall is provided with outside thread, and externally threaded top is installed a nut whole material-pumping tube is positioned on cover; The head of described suction tube is inserted in the endoporus of material-pumping tube extension part, and the outside interference fit of material-pumping tube is nested with an elastic seal ring, and by a retainer ring being connected with material-pumping tube extension part, sealing top is held on the bottom end of material-pumping tube extension part elastic seal ring.
Further, the little Spielpassung setting of the endoporus bottom of above-mentioned retainer ring and suction tube, the endoporus middle part of retainer ring is provided with one and coordinates corresponding seal ring mounting groove with described seal ring, and the endoporus top of retainer ring is provided with the internal thread being connected with material-pumping tube extension part outside thread bottom.
Further, the height of above-mentioned seal ring mounting groove is less than the height of elastic seal ring, and the internal thread length in retainer ring endoporus is less than the residue length of material-pumping tube extension part outside thread after screwing on nut.
Further, the bottom of above-mentioned seal ring mounting groove is set as reverse taper hole structure.
Further, the bottom of above-mentioned elastic seal ring is set as inverted cone body structure.
Further, the outer wall of above-mentioned retainer ring is provided with and strengthens the stressed rotation quil of finger.
The cooperation of the utility model suction tube by seal ring and retainer ring realizes with the effective sealing of material-pumping tube extension part and being connected, not only guaranteed the be connected hermetic seal of suction tube with material-pumping tube, and the suction tube after connecting is locking completely not, cleaning for convenience detach on the one hand, can carry out on the other hand 360 degree rotations and adjust, be convenient to the adjustment of suction tube installation direction.
Accompanying drawing explanation
Fig. 1, perspective exploded view of the present utility model;
Fig. 2, assembled sectional view of the present utility model.
Embodiment
As illustrated in fig. 1 and 2, a kind of material-pumping tube of paint spray gun bucket and suction tube Hermetical connecting structure, comprise cover 1, material-pumping tube 2 and suction tube 3.
The afterbody of described material-pumping tube 2 forms a junction 21 through whole cover 1 a test part, and joint 21 outer walls are provided with outside thread 211, and the top of outside thread 211 is installed a nut 4 whole material-pumping tube 2 is positioned on cover 1.
The head of described suction tube 3 is inserted in the endoporus of material-pumping tube extension part 21, the outside interference fit of material-pumping tube 3 is nested with an elastic seal ring 5, and by a retainer ring 6 being connected with material-pumping tube extension part 21, sealing top is held on the bottom end of material-pumping tube extension part 21 elastic seal ring 5.
The little Spielpassung setting of the endoporus bottom of above retainer ring 6 and suction tube 3, the endoporus middle part of retainer ring 6 is provided with one and coordinates corresponding seal ring mounting groove 61 with described seal ring 5, and the endoporus top of retainer ring 6 is provided with the internal thread 62 being connected with material-pumping tube extension part outside thread 211 bottoms.
At this, for further strengthening connection sealing and the join strength of suction tube 3 and material-pumping tube 2, the height of described seal ring mounting groove 61 is less than the height of elastic seal ring 5, and the length of retainer ring endoporus middle part internal thread 62 is less than the residue length of material-pumping tube extension part outside thread 211 after screwing on nut 4 simultaneously.This structure is arranged to protrude seal ring mounting groove 61Yi branch outside the top of elastic seal ring 5, when the bottom end of material-pumping tube extension part 21 and elastic seal ring 5 tops offset, retainer ring 6 revolves and further pushes elastic seal ring 5 on can also continuing, elastic seal ring 5 shortened expand and further hold the outer wall of suction tube 3 tightly, promoting both connection sealing and join strengths.
