Description
Technical field
The utility model relates to a kind of getter device.
Background technology
The connection of current urban sewage pipeline and access hole-claim building of inspection shaft many employing masonry structures again; That its making is loaded down with trivial details, complicated, operation is very inconvenient, cost compares is higher, sealing effectiveness is also undesirable; And destroy the back and rebuild relatively difficulty, not reproducible use, not recyclable.The birth of plastic inspection well has improved this phenomenon greatly; Shooting Technique is adopted in the manufacturing of current plastic inspection well mostly; Because the volume of plastic inspection well is bigger, thus need to adopt very big injection molding apparatus, its manufacturing cost than higher, production efficiency is lower.Therefore, in order to address this problem, people have expected making plastic inspection well with rotational molding technique; Yet; In daily production process, it is found that to have following technical problem: 1) some dead angles of mould be heated less, 2) wall thickness of the plastic inspection well place that need increase can't realize.
Therefore, be necessary to provide a kind of getter device that solves the problems of the technologies described above.
The utility model content
The utility model technical problem to be solved is: a kind of getter device simple in structure, easy to use is provided.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: getter device, and it comprises: interior cover, the overcoat and the nut that match with interior cover; Form a receiving space in said between cover and the overcoat; The said outer air inlet that communicates with receiving space that is arranged with, the said outer stage portion that is arranged with first through hole and is positioned at first through hole, an end of said first through hole is horn-like; Cover is installed in first through hole and with stage portion and connects in said; Be arranged with the upper surface that connects with stage portion in said, the central authorities of said interior cover are provided with second through hole that connects with first through hole, are provided with arc section between the upper surface of said interior cover and the hole wall of second through hole; Be provided with sealing ring between cover and the overcoat in said; The outer wall of cover is provided with external screw thread in said, and the inwall of said overcoat is provided with first internal thread that matches with external screw thread, and the inwall of said nut is provided with second internal thread that matches with external screw thread.
As a kind of optimized technical scheme, be arranged with first in said and tighten the hole, said nut is provided with second and tightens the hole.
The beneficial effect of the utility model is: in the utility model, compression pump is suppressed the air that contracts through air inlet in receiving space, then nut is unscrewed; Then cover in the rotation, narrow and small gap of formation between the stage portion of the upper surface of interior cover and overcoat, said compressed air can be from this gap in arc section flows to second through hole; Thereby the hot-air that drives in first through hole of top flows to downwards in second through hole, so just can heat be concentrated on the below of second through hole, this getter device is installed on the top of mould; Thereby can be to place, the dead angle heating of mould; In addition, when needs increase the local wall thickness of plastic inspection well, also can use the getter device in the utility model; The position that the getter device aligning is needed to increase wall thickness; Because the heat that this position receives is bigger, therefore fast more with regard to what melt at the plastics at this place, so formed herein wall thickness is also just thicker.Getter device in the utility model is simple in structure, and is easy to use, can concentrate heat.Getter device in the utility model is simple in structure, and is easy to use, can concentrate heat.

Among Fig. 1 to Fig. 4: 1, interior cover, 10, the upper surface, 100, getter device, 11, second through hole, 110, hole wall; 12, arc section, 13, external screw thread, 14, first tightens the hole, and 2, overcoat, 20, first through hole; 21, stage portion, 22, first internal thread, 3, nut, 30, second internal thread; 31, second tighten the hole, 4, receiving space, 5, air inlet, 6, sealing ring.
The specific embodiment
See also Fig. 1 to Fig. 4, getter device 100, it comprises: interior cover 1, the overcoat 2 and the nut 3 that match with interior cover 1; Form a receiving space 4 in said between cover 1 and the overcoat 2; Said overcoat 2 is provided with the air inlet 5 that communicates with receiving space 4, and said overcoat 2 is provided with first through hole 20 and is positioned at the stage portion 21 of first through hole 20, and an end of said first through hole 20 is horn-like; Cover 1 is installed in first through hole 20 and with stage portion 21 and connects in said; Cover 1 is provided with the upper surface 10 that connects with stage portion 21 in said, and the central authorities of said interior cover 1 are provided with second through hole 11 that connects with first through hole 20, is provided with arc section 12 between the upper surface 10 of said interior cover 1 and the hole wall 110 of second through hole 11; Be provided with sealing ring 6 between cover 1 and the overcoat 2 in said; The outer wall of cover 1 is provided with external screw thread 13 in said, and the inwall of said overcoat 2 is provided with first internal thread 22 that matches with external screw thread 13, and the inwall of said nut 3 is provided with second internal thread 30 that matches with external screw thread 13.Cover 1 is provided with first and tightens hole 14 in said, and said nut 3 is provided with second and tightens hole 31.During use, wooden stick is inserted first, second tighten in the hole, revolve tightlyer between cover 1 and overcoat 2 and the nut 3 in can making.
In the utility model, compression pump is suppressed the air that contracts through air inlet 5 in receiving space 4, then nut 3 is unscrewed; Then cover 1 in the rotation, narrow and small gap of formation between the stage portion 21 of the upper surface 10 of interior cover 1 and overcoat 2, said compressed air can be from this gap in arc section 12 flows to second through hole 11; Thereby the hot-air that drives in first through hole 20 of top flows to downwards in second through hole 11, so just can heat be concentrated on the below of second through hole 11, this getter device 100 is installed on the top of mould; Thereby can be to the heating of place, the dead angle of mould, avoid the mould inequality of being heated, in addition; When needs increase the local wall thickness of plastic inspection well; Also can use the getter device in the utility model, with the position of getter device 100 alignings needs increase wall thickness, because the heat that this position receives is bigger; What therefore the plastics at this place just melted is fast more, so formed herein wall thickness is also just thicker.Getter device in the utility model is simple in structure, and is easy to use, can concentrate heat.
