Abstract
The utility model discloses an engine joint component which comprises a nut (3) and a joint (1) with a flange (2) in the middle, wherein a first thread pipe (4) and a second thread pipe (5) are arranged on two sides of the joint (1); the nut (3) is screwed on the first thread pipe (4); threads of the first thread pipe (4) and the second thread pipe (5) are conical threads; an annular groove (6) is arranged between the second thread pipe (5) and the flange (2); a sealing ring (7) is sleeved in the annular groove (6). The engine joint component disclosed by the utility model is high in sealing property and is unlikely to leak.
Description
Technical field
The utility model relates to motor car engine field, especially a kind of motor adapter assembly.
Background technique
Adapter assembly is the vitals in motor, requirement has higher sealing, existing adapter assembly comprises joint and nut, screw thread on joint is generally metric thread, adopt direct screw thread to screw sealing,, easily there is the leakage of gas, liquid in this mode poor sealing performance that is tightly connected, causes engine failure.
Model utility content
Technical problem to be solved in the utility model is: overcome the defect of above prior art, a kind of motor adapter assembly of good seal performance is provided.
Technical solution adopted in the utility model is: a kind of motor adapter assembly, comprise nut and the middle joint with flange, the both sides of described joint are provided with the first threaded pipe and the second threaded pipe, described nut screws on the first threaded pipe, the first described threaded pipe and the screw thread of the second threaded pipe are tapered thread, between the second described threaded pipe and flange, be provided with annular groove, described annular groove inner sleeve has seal ring.
Adopt after above structure, the utility model motor adapter assembly compared with prior art has the following advantages: the screw thread of joint is tapered thread, higher than the general metric thread tightness using, there is self-tightening effect, unlike gapped between at the bottom of metric thread crest and tooth, the tapered thread gapless that can fit like a glove; Between the second threaded pipe and flange, increase seal ring, screw in the pipeline connecting at needs during at the second threaded pipe, increased sealing, guaranteed there will not be the situation of leakage simultaneously.
As preferably, described motor adapter assembly also comprises movable cutting ferrule, and described movable cutting ferrule one end is engaged in the first threaded pipe, and the other end is engaged in nut.Have higher flexibility compared with the existing fixing cutting ferrule being fixed on wanted connecting tube, as cutting ferrule is damaged, can only change cutting ferrule, part convenient maintenance and replacement, can not cause scrapping of assembly, has saved cost.
As preferably, one end of described movable cutting ferrule is engaged in the first threaded pipe and refers to, the endoporus of the first described threaded pipe is the cone shape hole of bigger diameter end away from the second threaded pipe, and described movable cutting ferrule is provided with corresponding chamfering with the contact position of the first threaded pipe internal tapered hole.In the time that joint screws, the cone shape hole sidewall in chamfering and first threaded pipe of movable cutting ferrule one end offsets, and oblique angle offsets and makes the sealability of joint better, difficult leakage, the other end and the nut of movable cutting ferrule offset, and cutting ferrule is fixed, and can not relatively move.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in the figure, the utility model motor adapter assembly, comprise nut 3 and the middle joint 1 with flange 2, the both sides of described joint 1 are provided with the first threaded pipe 4 and the second threaded pipe 5, described nut 3 screws on the first threaded pipe 4, the first described threaded pipe 4 and the screw thread of the second threaded pipe 5 are tapered thread, between the second described threaded pipe 5 and flange 2, are provided with annular groove 6, and described annular groove 6 inner sleeves have seal ring 7.
Described motor adapter assembly also comprises movable cutting ferrule 8, and described movable cutting ferrule 8 one end are engaged in the first threaded pipe 4, and the other end is engaged in nut 3.One end of described movable cutting ferrule 8 is engaged in the first threaded pipe 4 and refers to, the endoporus of the first described threaded pipe 4 is the cone shape hole 9 of bigger diameter end away from the second threaded pipe 5, and described movable cutting ferrule 8 is provided with corresponding chamfering 10 with the contact position of the first threaded pipe 4 internal tapered holes.
In the using process of the utility model motor adapter assembly, first movable cutting ferrule 8 is put into the cone shape hole 9 of the first threaded pipe 4 of joint 1 with one end of chamfering, the opening angle of cone shape hole is 24 °, then nut 3 and the first threaded pipe 4 are screwed, finally seal ring 7 is assembled in annular groove 6, the second threaded pipe 5 is for screwing and be connected with pipeline waiting.
Be described with regard to the utility model preferred embodiment above, but can not be interpreted as it is limitations on claims.The utility model is not only confined to above embodiment, and its concrete structure allows to change, and all various variations of doing in the protection domain of the utility model demand for independence are all in protection domain of the present utility model.
