Description

Corrugated pipe connector
Technical field
The utility model relates to a kind of corrugated pipe connector.
Background technique
The thin-wall corrugated tube that adopts stainless steel material to make at present can be crooked, and have the advantage of metal pipe concurrently, very is suitable for using in coal gas, the wet goods pipeline.The ripple pipe joint structure is not to have baroque defective in the prior art, has the irrational shortcoming of sealing configuration exactly.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of corrugated pipe connector of simple in structure, favorable sealing property.
For solving the problems of the technologies described above, the utility model is achieved through the following technical solutions: a kind of corrugated pipe connector, comprise adapter body, nut, one end of described adapter body is provided with outside thread, the other end of adapter body is provided with internal thread, described nut is provided with the outside thread that matches with the internal thread of adapter body, the internal channel of adapter body is provided with shoulder, the shoulder of adapter body is provided with seal washer, be provided with between seal washer and the nut and split slips, an end madial wall of splitting slips is provided with the fin that matches with the trench of bellows, the other end of splitting slips be provided with externally threaded nut one end and connect, the other end madial wall of nut is provided with the E RunddichtringO that cooperates with sylphon seal.
The beneficial effect of the utility model corrugated pipe connector is: in the technique scheme, owing to adopt the adapter body be provided with internal thread and be provided with externally threaded nut and be connected, strengthened the intensity of nut greatly, thereby increased the bulk strength of joint; During use the end face of bellows is inserted on the seal washer that the adapter body shoulder is provided with, the fin of splitting slips is stuck in the trench place of bellows, utilize the nut extruding to split slips, the place, protruding peak of bellows is squeezed in formation first road sealing on the seal washer tightly, simultaneously because the other end madial wall of nut is provided with the E RunddichtringO, the coating outer circumferential face of E RunddichtringO and bellows is sealed and matched and forms the sealing of second road, has therefore improved the sealability of joint greatly; And the utility model corrugated pipe connector also has simple in structure, easily manufactured advantage.
The utility model will be further described below in conjunction with the drawings and specific embodiments.

Fig. 1 is a kind of embodiment's of the utility model corrugated pipe connector a general structure schematic representation;
Fig. 2 is a corrugated pipe connector and general structure schematic representation after bellows is connected among Fig. 1;
Fig. 3 is a general structure schematic representation of splitting slips among Fig. 1;
Fig. 4 is a plan view of splitting slips among Fig. 3;
Fig. 5 is an A-A sectional view among Fig. 4;
Fig. 6 is a worm's eye view of splitting slips among Fig. 3.
Embodiment
As Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, shown in Figure 6, a kind of embodiment of the utility model corrugated pipe connector, comprise adapter body 1, nut 2, one end of described adapter body 1 is provided with outside thread, the other end of adapter body 1 is provided with internal thread, described nut 2 is provided with the outside thread that matches with the internal thread of adapter body 1, the internal channel of adapter body 1 is provided with shoulder 7, the shoulder 7 of adapter body 1 is provided with seal washer 6, be provided with between seal washer 6 and the nut 2 and split slips 3, an end madial wall of splitting slips 3 is provided with the fin 31 that matches with the trench of bellows, the other end of splitting slips 3 be provided with externally threaded nut 2 one ends and connect, the other end madial wall of nut 2 is provided with the E RunddichtringO 4 that cooperates with sylphon seal.In order further to improve the sealability of joint, be provided with O RunddichtringO 5 between described adapter body 1 and the nut 2, form three seals between adapter body 1 and the nut 2, further improved the sealability of joint, when joint is installed in the open air, owing to be provided with O RunddichtringO 5, can prevent that sealing or dust enter joint inside, so O RunddichtringO 5 also play waterproof and dustproof effect.Locate for the ease of bellows, described fin 31 end faces of splitting slips 3 are lower than the end face of splitting slips 3, the end face of splitting slips 3 forms the groove 33 that holds the protruding peak of bellows, can position bellows better, can effectively prevent the bellows displacement, split slips 3 and be provided with the flange 32 that adapts with nut 2 internal diameters with the end that nut 2 connects, the flange 32 of splitting slips 3 stretches in the nut 2, also can make to split slips 3 and obtain accurate in locating.For the ease of processing and ease of assembly, described flange 32 places of splitting slips 3 structure that is connected as one, as Fig. 3, Fig. 4, shown in Figure 5, add flange 32 places that the to split slips 7 man-hour structure that is connected as one, can do as a whole being enclosed within on the nut 2 with splitting slips 3 during the joint assembling, greatly facilitate assembling, because flange 32 places are thin-walleds, installation is easy to when needing break into two with one's hands splitting slips 3.
When the utility model uses, as shown in Figure 2, the end section covering layer of bellows 8 is peelled off, the trench and the protruding peak that expose bellows 8, the end of bellows 8 is inserted in the nut 2, make and peel off tectal bellows 8 ends and stretch out nut 2 and be provided with an externally threaded end, the coating of bellows 8 cooperates the formation sealing with the E RunddichtringO 4 of nut 2, to split slips 3 again breaks into two with one's hands from flange 32, the slips 3 of splitting that is divided into two is closed up the end that is enclosed within bellows 8 again the fin 31 of splitting slips 3 is snapped in one of them trench of bellows 8 ends, then bellows 8 is inserted in the adapter body 1, while locking nut 2, nut 2 promotes to split slips 3 and moves inwards, splitting slips 3 is being with bellows 8 to move inwards, thereby the several protruding peak pressures in the end of bellows 8 are contracted, be squeezed in tightly after the most protruding peak pressure of bellows 8 contracts and form sealing on the seal washer 6.
