Description
Technical field
The present invention relates to a kind of connector, be specifically related to a kind of flue connector.
Background technology
Flue just refers to the piping articles for the flue gas or washroom foul smell getting rid of kitchen cooking activity generation, it is the chief component of house kitchen, washroom common exhaust duct system, flue is be prefabricated into sulphate aluminium cement inner clip alkali-resistant glass fibre screen cloth or Portland cement inner clip gauze wire cloth and other reinforcing material to form mostly, flue connector is fixed together by two flues, makes it into as a whole connector.Flue and flue adopt vertical masonry joint to be spliced mostly, and then rely on steel nail to fix, but Problems existing is: steel nail is perishable, and distortion dislocation easily appears in the flue of vertical masonry joint splicing, makes to there is gap between flue pipe and flue pipe, easily causes smoke blowing to be leaked gas.Existing patent: CN203742128U, a kind of inner sleeve for flue docking, it comprise fit with flue end medial surface to female connector, the described middle part to female connector lateral surface is surrounded with convex edge band, is describedly set in flue junction to female connector.Although above-mentioned patent does not need steel nail to connect, also prevent flue to be out of shape dislocation to a certain extent, Problems existing is: the flue of only being fitted by inner sleeve connects firm not, simultaneously poor sealing.
Summary of the invention
The object of the present invention is to provide and a kind ofly flue is firmly connected and the good flue connector of sealing.
To achieve these goals, the application proposes a kind of flue connector, it is by female connector be arranged on and dock the sealing ring that puts and form, described female connector to be made up of square upper straight tube and lower straight tube and the junction plate that is connected straight tube and lower straight tube, described upper straight tube and lower straight tube are hollow-core construction, described upper straight tube and upper flue medial surface fit, described lower straight tube and lower flue lateral surface fit, described junction plate is provided with the square hole mated with upper straight tube, described groove is provided with to the face that female connector and flue are fitted, the sealing ring be made up of elastomeric material is provided with in described groove, the width of described sealing ring is greater than the degree of depth of groove.
Compared with prior art, the present invention has following advantages: described upper straight tube and upper flue medial surface fit, and described lower straight tube and lower flue lateral surface fit, and there is interaction force between upper lower flue, flue can be prevented to be out of shape dislocation, make connection more firm; The laminating of described upper straight tube and upper flue, lower straight tube and lower flue is plane-plane contact, seals flue, and the sealing ring simultaneously put with docking contacts, and also seals flue, is equivalent to form double seal, better tightness.
As preferred scheme, the cross sectional shape of described sealing ring is right-angled triangle, and sealing ring maximum outside diameter place is positioned at below, and the side of flue and end face can be sealed, and strengthens the sealing connected.
As preferred scheme, when described upper straight tube and upper flue, lower straight tube and lower flue are fitted, the side of flue and straight tube is interference fit, makes flue and tightr to the connection of female connector.
As preferred scheme, described transition face female connector turning point being provided with to inclination, makes flue gas by which better flue junction.
Accompanying drawing explanation
Fig. 1 is structure chart of the present invention;
Fig. 2 is the sectional view that connector of the present invention and flue portion are fitted;
Fig. 3 is the sectional view that connector of the present invention and flue are fitted completely.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
A kind of flue connector as shown in Figure 1, comprises sealing ring 2 and to female connector 3; Female connector 3 is provided with to the groove 5 placing sealing ring 2, the inner turning point of female connector 3 is provided with to the transition face 6 of inclination.
As shown in Figure 2, when upper flue 1 is connected with lower flue 4, the medial surface of upper flue 1 with the lateral surface of female connector 3 is fitted, the lateral surface of lower flue 4 with the medial surface of female connector 3 is fitted, interference fit is to the laminating of female connector 3 and upper flue 1 and lower flue 4, the upper flue 1 docked up and down is together with lower flue 4 compact siro spinning technology, upper flue 1 and lower flue 4 are fitted respectively with to lateral surface in female connector 3 simultaneously, lower flue 4 has outside active force to female connector 3, therefore outside active force is also had to female connector 3 pairs of upper flues 1, make female connector 3 and upper flue 1 compact siro spinning technology, in like manner upper flue 1 make lower flue 4 with to female connector 3 compact siro spinning technology, upper flue 1 and lower flue 4 can be prevented to be out of shape dislocation, make connection more firm simultaneously.
As shown in Figure 3, upper flue 1 and lower flue 4 continue to dock forward, when upper flue 1 and lower flue 4 touch the sealing ring 2 of right-angle triangle, because sealing ring 2 can produce deformation elastomeric material when being stressed is made, the resistant to elevated temperatures plastic cement of such as acid and alkali-resistance, when sealing ring 2 is subject to upper flue 1 and lower flue 4 applied pressure, there is metamorphosis, sealing ring 2 respectively with the medial surface of upper flue 1 and the lateral surface of lower flue 4, and the upper surface of the lower surface of upper flue 1 and lower flue 4 tightly fits together, be equivalent to seal the side of upper flue 1 and lower flue 4 and end face simultaneously, add upper flue 1 and lower flue 4 and be interference fit to female connector 3, be equivalent to carry out triple seal to the connection of upper flue 1 and lower flue 4, sealing is good, the inner turning point of female connector 3 is provided with to the transition face 6 of inclination, make flue gas by which better the junction of upper flue 1 and lower flue 4.
The foregoing is only the detailed description of present pre-ferred embodiments, be not used for limiting the present invention, all embodiments complying with the similar change that creation spirit of the present invention is done, all should be contained among the present invention.
