Abstract
The utility model discloses a steel band bellows, comprising a main body, left first wave form recess, left second wave form recess and the left third wave form recess of main part left end in adopt fused mode all to set firmly one deck left side sealing layer, right first wave form recess, right second wave form recess and the right third wave form recess of main part right -hand member in adopt fused mode all to set firmly one deck right side sealing layer, left sealing layer and right sealing layer all adopt the polyethylene melting to make. The utility model has the advantages of convenient to use, leakproofness are good.
Description
Technical field
The utility model relates to a kind of steel band bellows, is applied to the production and processing field of steel band bellows.
Background technique
At present, steel band bellows has been widely used in the lives such as effluent discharge, in the using process of steel band bellows, because length is inadequate, need bellows to be connected together reach the object increasing length, Electric thermal smelting belt is mainly adopted to connect the Placement be connected with heat-contraction sleeve in the market, but, Electric thermal smelting belt is very narrow, this just causes the sealability connecting rear bellows poor, and heat-contraction sleeve only has several millimeters thick, after welding has been got well, bellows entirety not easily moves, easily cause the defect that bellows ruptures, also the mode adopting clip connected is had in addition, but the foam that blocks water of the liner defect that equally can cause poor sealing performance of long duration, at present, in order to solve the poor sealing performance of the steel band bellows linked together, working life is short, the problem of easy to leak, at present, staff starts the Placement proposing to adopt electric heating melting sleeve, namely by the right-hand member of the bellows in left side being inserted the inside of the left side of electric heating melting cover, the left end of the bellows on right side is inserted into the inside of the right-hand part of electric heating melting cover, then to electric heating melting cover electrified regulation, together with the two ends, left and right that electric heating melting overlaps then are adhesively secured to the bellows of the left and right sides, but owing to steel band bellows there being the contoured shaped recess formed in steel strip winding process, gap is formed because of contoured shaped recess between the internal surface meeting of electric heating melting cover and bellows, this sealing just causing bellows and electric heating melting to overlap joint is not still fine, still there will be the situation that sewage exosmoses from joint.
Model utility content
For solving the defect of prior art, the utility model discloses that a kind of structure is simple, the steel band bellows of good airproof performance.
The utility model discloses a kind of steel band bellows, comprise main body, the mode of melting is adopted all to set firmly the left sealing layer of one deck in the left first wave connected in star of described main body left end, left Second Wave connected in star and left 3rd contoured shaped recess, adopt the mode of melting all to set firmly the right sealing layer of one deck in the right first wave connected in star of described main body right-hand member, right Second Wave connected in star and right 3rd contoured shaped recess, described left sealing layer and right sealing layer all adopt polyvinyl plastics melting to make.
Owing to adopting technique scheme, the utility model has following advantageous benefits:
1, easy to use;
2, good seal performance.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of steel band bellows of the utility model.
Wherein: 1-main body; The left first wave connected in star of 11-; The left Second Wave connected in star of 12-; Left 3rd contoured shaped recess of 13-; The left sealing layer of 14-; The right first wave connected in star of 15-; The right Second Wave connected in star of 16-; Right 3rd contoured shaped recess of 17-; The right sealing layer of 18-.
Embodiment
As shown in Figure 1, the utility model discloses a kind of steel band bellows, comprise main body 1, the mode of melting is adopted all to set firmly the left sealing layer 14 of one deck in the left first wave connected in star 11 of described main body 1 left end, left Second Wave connected in star 12 and left 3rd contoured shaped recess 13, adopt the mode of melting all to set firmly the right sealing layer 18 of one deck in the right first wave connected in star 15 of described main body 1 right-hand member, right Second Wave connected in star 16 and right 3rd contoured shaped recess 17, described left sealing layer 14 and right sealing layer 18 all adopt polyvinyl plastics melting to make.
The utility model implements like this: when using electric heating melting cover to connect together two steel band bellows described in the utility model, right-hand member by the main body 1 of the steel band bellows of the present utility model in left side inserts the inside of the left side of electric heating melting cover, the left end of the main body 1 of the steel band bellows on right side is inserted into the inside of the right-hand part of electric heating melting cover, then to electric heating melting cover electrified regulation, the steel band bellows of the left and right sides is then adhesively secured to together by the two ends, left and right of electric heating melting cover, due to the left first wave connected in star 11 of main body 1 left end of steel band bellows, the mode of melting is adopted all to set firmly the left sealing layer 14 of one deck in left Second Wave connected in star 12 and left 3rd contoured shaped recess 13, the right first wave connected in star 15 of main body 1 right-hand member, the mode of melting is adopted all to set firmly the right sealing layer 18 of one deck in right Second Wave connected in star 16 and right 3rd contoured shaped recess 17, like this, electric heating melting cover is except together with being adhesively secured to main body 1, together with the internal surface of electric heating melting cover can be adhesively secured to the right sealing layer 18 of the steel band bellows right-hand member in left side in addition, together with the internal surface that electric heating melting overlaps also can be adhesively secured to the left sealing layer 14 of the steel band bellows left end on right side, gap would not be produced like this because of between the main body 1 of internal surface and left and right two steel band bellows that steel band bellows causes electric heating melting to overlap because forming contoured shaped recess in steel band winding process, therefore sealability is relatively good, use more convenient.
Last it is noted that above embodiment only in order to illustrate the utility model and and technological scheme described by unrestricted the utility model; Therefore, although this specification has been described in detail the utility model with reference to each above-mentioned embodiment, those of ordinary skill in the art should be appreciated that and still can modify to the utility model or equivalent replacement; And all do not depart from technological scheme and the improvement thereof of spirit and scope of the present utility model, it all should be encompassed in right of the present utility model.
Claims (1)
