Specific embodiment
In the following, being described further in conjunction with attached drawing and specific embodiment to the utility model, it should be noted that
Under the premise of not colliding, it can be formed in any combination between various embodiments described below or between each technical characteristic new
Embodiment.
As shown in Figs. 1-2, it shows the utility model and a kind of reducer union of offer of grinning is provided.The reducer union is at least wrapped
It includes: the first noumenon 1 and the second ontology 2.Wherein, the first noumenon 1 offers first through hole 13, and 1 first end of the first noumenon is equipped with
First threaded portion 14,1 second end of the first noumenon are provided with the first flange 11 and the second flange 12, the first threaded portion 14, first
Flange 11 and the second flange 12 are respectively positioned on 13 axial direction of first through hole, and 11 to the second flange 12 of the first flange is closer to
One ontology, 1 second end.Second ontology 2 offers the second through-hole 21, and 2 first end of the second ontology is equipped with the second threaded portion 22, and second
Threaded portion 22 is located on 21 axial direction of the second through-hole, the diameter of the connection screw thread of the first threaded portion 14 and the second threaded portion 22
Connection with the diameter of thread difference, the second through-hole 21 at 2 second end of the second ontology be stepped hole 211.First flange 11 is suitable
In being caught in stepped hole 211, and the first flange 11 can be relatively rotated with stepped hole 211, and the second flange 12 is suitable for and the second ontology 2 the
Two end end abutments.
In actual use, it referring to shown in Fig. 3, when reducer union first end and cabinet body 4 or needs to wear pipeline
Board connection fastening and reducer pipe second end connect fastening with cable protective pipe 5, and cable protective pipe 5 is elbow
When, it is possible that situation as shown in Figure 3, i.e. the direction of cable protective pipe 5 is downward, and the trend of cable is from upper past
Under walk, to will lead to cable in this way cannot be introduced into cable protective pipe 5.And by the reducer union of the utility model, though its two
End has connected fastening, also can be by the relative rotation of the first noumenon 1 and the second ontology 2, to adjust the court of cable protective pipe 5
To, it can by cable protective pipe 5 in Fig. 3 by being adjusted to upward downward, so that it is consistent with the practical trend of cable, to guarantee
Cable can smoothly be fit into cable protective pipe 5.
Referring to Fig. 4, the second through-hole 21 is stepped hole 211 at 2 second end of the second ontology, and there are three the tools of stepped hole 211
Face, the first face 212, the second face 213 are the face parallel with 211 axis of stepped hole, and the aperture where the first face 212 is less than the
Aperture where two face 213, third face 214 is the face for connecting the first face 212 and the second face 213.It is to be appreciated that when the
One flange 11 enters stepped hole 211, and after 2 second end end abutment of the second flange 12 and the second ontology, can pass through external force
Make the first flange 11 deformation occurs to abut the first flange 11 with third face 214 to stick into stepped hole 211.Pass through the second flange
12 abut and the first flange 11 is abutted with third face 214 with 2 the second end of the second ontology, can make the first noumenon 1 and
Relative motion does not occur in the axial direction for two ontologies 2, i.e. the first noumenon 1 and the second ontology 2 is to connect in this way
Together.While such connection type can make the first noumenon 1 and the second ontology 2 link together, and can phase
To rotation.
Preferably embodiment, offers outer channel 15 on the first noumenon 1, outer channel 15 be located at the first flange 11 with
And second between flange 12, and sealing ring 3 is configured in shown outer channel 15, it is close when the first flange 11 is caught in stepped hole 211
Seal 3 is abutted with 211 hole wall of stepped hole.It is mentioned here to be abutted with 211 hole wall of stepped hole, it is interpreted as abutting with the first face 212.
