Abstract

The utility model relates to a flexible pipe joint, which comprises a rubber pipe and at least two clamps. The utility model is characterized in that the utility model also comprises a protective sleeve of a spring, wherein, the length of the protective sleeve of a spring is smaller than that of the rubber pipe and the protective sleeve of a spring centrally coats an outer layer of the rubber pipe. In addition, both ends of the rubber pipe are respectively sheathed with at least one clamp of big fastening force. The utility model can avoid that the rubber pipe is directly sunned by the sun to age, and therefore, the service life of the rubber pipe is extended. The utility model has the advantages of bearing capacity increase, safe operation and good interchangeability, and the rubber pipe is not easy to break. Under the protection of the sleeve of a spring, big flexible deformation can be allowed. The utility model is especially suitable for the conditions that water pipes at both ends have big radial displacement.

Description

Flexible coupling

The utility model relates to a kind of pipe joint, relates in particular to a kind of flexible coupling.

Common water-cooling tube joint is the General Purpose Rubber pipe, two ends are respectively with a clip, it is loosening easily under pipe joint frequent vibration, impact usually, rubber pipe is exposed to the sun and rain very easily aging, and working life is short, and bearing capacity is low, again, hydraulic action and being out of shape in managed has under the situation of big radial misalignments deformation extent big at the two ends water pipe, often outwards expand into cydariform even break.

Main purpose of the present utility model is to provide a kind of bearing capacity big, and rubber pipe is difficult for breaking, and is safe and reliable, the flexible coupling that can increase the service life.

The purpose of this utility model is to realize like this; a kind of flexible coupling; it comprises rubber pipe, at least two clips; it is characterized in that; it also comprises the spring protection cover, the length that is shorter in length than described rubber pipe of this spring protection cover, and be coated on the skin of described rubber pipe between two parties; again, the two ends of this rubber pipe respectively put at least one big fastening force clip.

Owing to adopted above-mentioned technical solution; be rubber pipe outside sleeve spring protecting jacket, the utility model flexible coupling can be avoided occurring rubber pipe and tanned by the sun by the sun and wear out, and extended its working life; simultaneously; its bearing capacity is increased to more than the thirtyfold of existing working pressure, and rubber pipe is difficult for breaking, and is safe and reliable; and under the protection of spring housing; can allow bigger flexible deformation, interchangeability is good, is particularly useful for the situation that the two ends water pipe has big radial misalignments.

Below in conjunction with embodiment's accompanying drawing the utility model is further described.

Fig. 1 is a kind of embodiment's perspective view of the present utility model;

Fig. 2 is that the A of Fig. 1 is to cross-sectional view;

Fig. 3 is the another kind of embodiment's of the utility model a major profile structural representation.

By illustrated in figures 1 and 2; a kind of embodiment of the utility model flexible coupling; it comprises rubber pipe 7, at least two clips 8; spring protection cover 9; the length that is shorter in length than described rubber pipe 7 of this spring protection cover 9; and be coated on the skin of described rubber pipe 7 between two parties, again, the two ends of this rubber pipe 7 respectively put at least one big fastening force clip 8.Described big fastening force clip 8 comprises: thin steel band 1, screw 3, last cylinder 4, lower prop 4 ', the thin steel inserted sheet 5 of one shallow arcuation and a check washer (not marking among the figure), described thin steel band 1 can form the round of 360 ° of openings, the neutral position of last cylinder has perforation 41, the neutral position of lower prop all attacked threaded perforations 41 ', the two end part of described thin steel band 1 all are the annular ends 11 that have annular distance 112, and on the end face of the arc of this annular end, have notch 111, on described, lower prop is located in respectively in the annular distance 112 of each annular end 11 that approaches steel band, and the tapped hole 41 of the perforation 41 of this last cylinder and lower prop ' just in time be in the notch 111 of described annular end 11, described screw 3 by check washer pass successively the perforation 41 of cylinder on this and the threaded perforations 41 of lower prop ', make, lower prop 4,4 ' spacing can regulate by the rotation of this screw 3, thereby control clip size.Should approach the opening internal surface that steel inserted sheet 5 is arranged on described thin steel band 1, the do welding of its end and thin steel band 1 is fixing, and the internal surface of the other end and thin steel band 1 can relatively move.Lock better for the ease of check washer, the cylinder face that contacts with check washer can be to make plane 42 usually.

By shown in Figure 3, the another kind of embodiment of the utility model flexible coupling, its main structure is the same, just its big fastening force clip is by two thin steel bands 1, two screws 3, the neutral position all have perforation 41 two go up cylinder 4 and neutral position all attack threaded perforations 41 ' lower prop 4 ', two thin steel inserted sheets 5 and two check washers (not marking among the figure) are formed, wherein thin steel band 1 can form the semicircle shape of 180 ° of openings, and two ends of every thin steel band 1 all are the annular ends 11 that have annular distance 112, on the end face of the arc of this annular end 11, have notch (as the notch among Fig. 1 111), again, the cast of a both sides symmetrical openings of these two thin steel band 1 involutory compositions, go up in the annular distance 112 of two annular ends 11 that cylinders 4 are located in a thin steel band 1 respectively for described two, in the annular distance 112 of two annular ends 11 of the thin steel band 1 of another root of described two lower props 4 ' be located in respectively, and should go up the perforation 41 of cylinder 4 and this lower prop 4 ' threaded perforations 41 ' just in time be in the notch of described each annular end 11, and by the notch of each annular end 11 with described each screw 3 by a slice loosen pad pass successively respectively the perforation 41 of cylinder 4 and lower prop 4 ' tapped hole 41 ' in, make, following two cylinders 4,4 ' spacing can regulate by the rotation of this screw 3, thereby control clip size.Described each thin steel inserted sheet 5 is separately positioned on the internal surface of the opening that described two thin steel bands 1 are combined to form, and its end fixes with the internal surface of a thin steel band 1 and is connected, and the internal surface of the other end and another thin steel band 1 can relatively move.Lock better for the ease of check washer, the face of the last cylinder that contacts with check washer can be to make plane 42 usually.
