The utility model discloses a connecting pipe fitting, which comprises an extended and contracted sylph bellows and joints arranged on two ends of the sylph bellows, wherein the joint is provided with a screw cap check ring, the screw cap check ring is provided with an assisting fixing part connected with the joint every section of tube, the assisting fixing part is provided with a screw cap on the tube between the screw cap check ring, the sylph on bellows is provided with an outer thread on the tube outer surface of the joint end on the other end, and is also arranged on the bottom along the outer thread with an assisting fixing part connected with the joint. The utility model is suitable for joints with different connecting function and is good in leakproofness and convenient in different situations.
Description
Technical field
The utility model relates to a kind of connection pipe fitting, refers in particular to a kind of sanitary equipment, transferring oil, the employed connection pipe fitting of gas.
Background technique
Connection pipe fitting be widely used in water supply pipe with the dish that washes one's face, wash being connected between the cleaners and polishes such as vegetable dish, water heater, water closet being connected between the pipeline that also can be used for transferring oil, gas and non-corrosiveness medium and the use equipment.As shown in Figure 1, the existing connection pipe fitting in above-mentioned field that is usually used in is made up of the bellows 1 of an inflexibility, no Telescopic, the movable nut 2 that is placed in bellows 1 two ends, adopts omissive representation in bellows 1 accompanying drawing 1.In order to reach sealing effect, also be provided with seal washer 4 at the end face of bellows 1.Above-mentioned connection pipe fitting two ends all are to establish movable nut 2, when connecting if desired, just can connect by other male element, and attachable scope has narrow limitation.And two movable nuts 2 can slidably reciprocate 1 of bellows under the situation that does not have connection, can cause rigidity friction between nut 2 and the bellows 1 before use, thereby influence the quality and the outward appearance of pipe fitting.Bellows 1 inflexibility, no Telescopic, there is narrow limitation in installable place, installing when firm, can only be unilaterally to play perpendicular solid effect by being enclosed within pipe fitting upper cap nut 2 in addition, seals, fastening poor performance.
Summary of the invention
The purpose of this utility model is to provide a kind of connection pipe fitting, and it has the joint that is applicable to different Placements, and good airproof performance, and connecting tube is flexible, flexible, and use in convenient different place.
In order to achieve the above object, the utility model is realized by following technological scheme.
A kind of connection pipe fitting, comprise scalable, a crooked bellows and the joint of being located at the bellows two ends, it is characterized in that: the joint end of bellows one end is provided with the nut back-up ring, be provided with an assisted fasteners that is connected with the joint one along the one section body in nut back-up ring interval, be arranged with a nut on the body between assisted fasteners and the nut back-up ring; Connector end body periphery at the bellows the other end is provided with one section outside thread, is provided with an assisted fasteners that is connected with the joint one along the outside thread below.
The selectable replacement scheme of the utility model is, joint end at the bellows two ends is provided with the nut back-up ring, be provided with an assisted fasteners that is connected with the joint one along the one section body in nut back-up ring interval, be arranged with a nut on the body between assisted fasteners and the nut back-up ring.
The utility model beneficial effect is, be provided with joint at the bellows two ends, on joint, be arranged with nut, gap between swagelok and the nut is very little, again in conjunction with high temperature resistant, corrosion resistant gasket seal, more guarantee sealing effect, and nut can not influence the quality and the outward appearance of bellows only with movable between assisted fasteners and nut back-up ring.Adopted scalable, crooked bellows, convenient different occasion is used.Can or be threaded by nut on joint, attachable scope is big, is applicable to different Placements.On joint, also be provided with the assisted fasteners that is connected with the joint one, can make pipe fitting and be connected object and connect more closely by fastened tools.Connection pipe fitting of the present utility model can be widely used in water supply pipe and the dish that washes one's face, wash cleaners and polishes such as vegetable dish, water heater, water closet in the middle of be connected being connected between the pipeline that also can be used for transferring oil, gas and non-corrosiveness medium and the use equipment.
