Abstract
The utility model discloses an exhaust tooling component for an air exhauster, which avoids air leakage during aeration and exhaust and has long service life. The exhaust tooling component for the air exhauster adopts the structure that an inner ring-shaped groove and an outer ring-shaped groove are formed on one side surface of a basal body, the inner ring-shaped groove is positioned in the outer ring-shaped groove, one end of an exhaust pipeline is communicated with the bottom of the inner ring-shaped groove, one end of an exhausted pipeline is communicated with a central lug boss surface of the inner ring-shaped groove, a planar rubber bowl is embedded and fixed in the outer ring-shaped groove, a blind rivet is fixedly mounted at the central outer side part of the planar rubber bowl, and the outer end part of the blind rivet is fastened and connected with one end of a pull rod.
Description
Technical field
The utility model relates to bulb production equipment technical field, particularly a kind of exhaust frock assembly of air exhauster of bulb production usefulness.
Background technology
The exhaust frock assembly of on the Halogen lamp LED air exhauster, using at present by matrix 1, exhaust pipe 5, formed by exhaust pipe 6, pull bar 4, O-ring seals 2,3, referring to shown in Figure 1.Exhaust pipe 5, all be located in the matrix 1 and mutually by the passage of exhaust pipe 6 and pull bar 4 and connect, in the tie rod end groove of this perforation place, O-ring seals 2 is housed, can control to exhaust pipe 5 with by the connection of exhaust pipe 6 or disconnection, promptly engage with corresponding matrix 1 or separate by O-ring seals 2, reach exhaust pipe 5 with by disconnection between the exhaust pipe 6 or be communicated with.Need between the straight bar section of pull bar 4 and the matrix 1 with a plurality of O-ring seals 3 sealings.The existing shortcoming of this structure: be in the continuous reciprocating motion of pull bar 4, friction between O-ring seals 3 and the matrix 1 is worn and torn O-ring seals 3 easily, causes gas leakage, outside air is entered caused bulb vacuum degree to reduce in the exhaust pipe 6, bulb life shortens.
Summary of the invention
The purpose of this utility model is to provide that can not leak gas and the exhaust frock assembly of using on a kind of bulb air exhauster long working life.
The technical solution that the utility model proposed is such:
A kind of exhaust frock assembly of air exhauster, comprise matrix, pull bar, be positioned at the exhaust pipe of matrix and by exhaust pipe, annular groove and annular groove outside in described matrix one side is provided with, interior annular groove is positioned at the annular groove outside the inside, the bottom land of described exhaust pipe one end and interior annular groove connects, described by exhaust pipe one end and the perforation of interior annular groove central boss face, be fixed with plane glue bowl at the embedded dress of annular groove outside, this plane glue bowl central authorities outside portion is fixed with blind rivet, and this blind rivet outer end and pull bar one end are fastenedly connected.
The central region of described plane glue bowl is plane.
Compared with prior art, the utlity model has following beneficial effect:
The utility model is used for exhaust frock assembly on the bulb air exhauster at the control exhaust pipe with by the disconnection between the exhaust pipe or when being communicated with, by pull bar and blind rivet drive glue bowl middle part, plane plane domain be fitted in annular groove central boss face or leave this boss face and realize, such glue bowl plane and matrix boss face sealing area are big, good seal performance, and the exhaust frock assembly of the having avoided existing air exhauster fully gas leakage problem that occurs easily wearing and tearing and take place because of long-term reciprocating motion between 0 shape sealing ring on the pull bar and the matrix passage.In addition, because seal is not done relative motion with other parts, so its long working life.
Description of drawings
Fig. 1 is the exhaust frock modular construction schematic diagram that uses on the existing bulb air exhauster.
Fig. 2 is the exhaust frock modular construction schematic diagram of the air exhauster of an embodiment of the utility model, be exhaust pipe shown in the figure with by the exhaust pipe connected state.
Fig. 3 be air exhauster shown in Figure 2 exhaust frock assembly exhaust pipe with by the structural representation of exhaust pipe off-state.
Fig. 4 is the multilayer overlapped in series structural representation of the exhaust frock assembly of air exhauster shown in Figure 3.
Embodiment
By following embodiment the utility model is further elaborated.
Referring to Fig. 2, shown in Figure 3, the exhaust frock assembly of using on a kind of bulb air exhauster is by matrix 11, be positioned at the exhaust pipe 15 of matrix 11, by exhaust pipe 16, plane glue bowl 12, blind rivet 13 and pull bar 14 are formed, annular groove 17 and annular groove outside 18 in a side of matrix 11 is provided with, interior annular groove 17 is positioned at annular groove outside 18 the insides, the bottom land of exhaust pipe 15 1 ends and interior annular groove 17 connects, connected by the central boss face of exhaust pipe 16 1 ends and interior annular groove 17, setting-in is fixed with plane glue bowl 12 in annular groove outside 18, these plane glue bowl 12 central outside portions are fixed with blind rivet 13, blind rivet 13 outer ends and pull bar 14 1 ends are fastenedly connected, and the central region of plane glue bowl 12 is plane.Pull bar 14 is pulled outward, matrix 11 1 sides are left at the position, plane of plane glue bowl 12, at this moment exhaust pipe 15 be communicated with by exhaust pipe 16, gas can interconnect, if pull bar 14 is pushed back, the central boss face of matrix 11 is being pasted at the position, plane of plane glue bowl 12, at this moment exhaust pipe 15 with disconnected by exhaust pipe 16, the exhaust frock assembly of air exhauster is in the pipeline off-state, referring to shown in Figure 3.
Actual needs according to using can increase to 2 or 3 overlapped in series with above-mentioned exhaust frock assembly, as exhaust and inflation usefulness, as shown in Figure 4.
The exhaust frock assembly of the air exhauster of the flat bowl of the utility model formula glue bowl sealing need not use the O-ring seals sealing, thereby, thoroughly solve O-ring seals and caused the problem of leaking gas because of wearing and tearing in sliding coming and going.
