In the present embodiment, the blocking portion 121 that is substantially perpendicular to the axial direction of the pipe joint body 1 is formed at the end of the first receiving portion 122 that is relatively far from the pipe joint abutting portion 13, but of course, the blocking portion 121 does not have to be provided perpendicular to the axial direction of the pipe joint body 1, and it is only necessary to achieve that the adapter 2 can abut against the blocking portion 121.

Further, referring specifically to fig. 4, the retainer 4 of the present embodiment includes a deformation portion 41, a base portion 42 and a retainer through hole portion 43, in the present embodiment, the base portion 42 is located at an end of the deformation portion 41 relatively close to the screw abutting portion 33 (to be mentioned later), the deformation portion 41 is a cylindrical structure or a truncated cone structure having a substantially hollow shape, the base portion 42 is a circular ring structure having a substantially hollow shape, the retainer 4 is a substantially hollow shape, and the retainer through hole portion 43 is provided at a substantially middle position of the retainer 4, through which the adapter tube 2 can pass.

Referring to fig. 1 in particular, the sealing member 5 provided in this embodiment is an O-ring, most of which is located in the second receiving portion 123, and the adapter tube 2 can pass through the central through hole of the sealing member 5, and the sealing member 5 is externally sleeved on the surface of the adapter tube 2, so that the sealing member 5 and the adapter tube 2 are sealed.

Referring to fig. 6 in particular, the pipe joint assembly provided by the present embodiment includes a threaded member 3, the threaded member 3 is provided with a threaded member portion 32 and a threaded member through hole portion 31, the threaded member through hole portion 31 can be passed through by the connecting pipe 2, in addition, the inner end surface of the threaded member 3 is further provided with a threaded member abutting portion 33, and the threaded member abutting portion 33 can abut against the base portion 42 of the clamping member 4.

In the present embodiment, in a state where the adapter 2 and the retainer 4 are not yet assembled, the outer diameter of the adapter 2 is smaller than the inner diameter of the retainer passage portion 43, so that the retainer 4 can be relatively easily fitted around the adapter 2, and in the process of mounting the coupling body 1 to the adapter 2, the seal 5 can be first placed in the second receiving portion 123 of the coupling body 1, then the adapter 2 is inserted through the screw passage portion 31 and the retainer passage portion 43 in this order, then the adapter 2 is inserted into the first receiving portion 122 from the open end of the coupling body 1, and finally the screw thread portion 32 and the coupling thread portion 11 are screw-engaged, and in the process of screwing the screw 3 and the coupling body 1, the retainer 4 is gradually moved in a direction approaching the coupling abutment portion 13 by the pressure of the screw 3, due to the direction of inserting the adapter 2 into the receiving portion 12 in the axial direction of the coupling head assembly, the internal diameter of coupling butt portion 13 reduces gradually, therefore when chucking spare 4 moves to a certain extent, deformation portion 41 can offset with coupling butt portion 13, at this moment, continue to twist and move screw member 3, deformation portion 41 can take place to warp, and its internal diameter and external diameter all diminish gradually, and chucking spare 4 can continue to move, and until deformation portion 41 offsets with takeover 2, chucking spare 4 and takeover 2 interference fit fixed connection this moment can form hard seal between takeover 2 and the deformation portion 41.

In order to increase the deforming effect of the deforming portion 41 of the retainer 4, the pipe joint assembly of the present embodiment is further configured such that: the tapered angle of the pipe joint abutment portion 13 is larger than the tapered angle of the deformation portion 41, and at this time, the deformation portion 41 is more likely to be deformed in the movement direction of the retainer 4.

Of course, the deformable portion 41 and the base portion 42 are not clearly defined, and for example, when the entire retainer 4 is of a circular truncated cone shape, the surface of the retainer 4 that abuts against the screw abutting portion 33 is the base portion 42, and the remaining portions are the deformable portions 41, and in the configuration of the retainer 4 shown in fig. 4, the substantially annular portion thereof is the base portion 42, and the circular truncated cone-shaped portion thereof is the deformable portion 41, and in the present embodiment, the deformable portion 41 and the base portion 42 are of an integral structure.

The coupling subassembly 1 that this embodiment provided, its coupling body 1 is comparatively convenient with being connected of takeover 2, only need can realize coupling body 1 and being connected of takeover 2 through the mode of screwing up coupling body 1 with screw member 3, and screw member 3 and coupling body 1 screw thread cooperation back, not only can realize sealing member 5 and takeover 2 sealed, can also realize the sealed of chucking spare 4 and takeover 2 through the deformation of chucking spare 4, the coupling subassembly that this embodiment provided, its soft seal and hard seal cooperation, the sealed effect of coupling subassembly is better.

In the background art, one end of the connecting pipe is flared, the strength of the connecting pipe is reduced compared with that of the connecting pipe without flaring, in addition, the flaring part of the connecting pipe is propped between the connector and the connecting pipe threaded piece, and the force borne by the flaring part is larger.

Furthermore, in this embodiment, thereby make the connection of takeover 2 and coupling body 1 through chucking spare 4, this fixed mode is comparatively convenient, only need to insert takeover 2 in chucking spare through-hole portion 43, rely on chucking spare 4 to take place to warp and make chucking spare 4 be connected with takeover 2, in addition, the both sides of chucking spare 4 offset with screw abutting portion 33 and coupling abutting portion 13 respectively, when external force wants to make takeover 2 and coupling body 1 separate, the power that takeover 2 received can transmit to screw 3 through chucking spare 4, and because screw 3 is fixed through threaded connection with coupling body 1, consequently, make takeover 2 and coupling body 1 separate required power also great.

In addition, the pipe joint assembly of this embodiment is also more convenient, only need to make the screw member 3 rotate towards the orientation of unscrewing for coupling body 1, can realize that screw member 3 and coupling body 1 separate, and the operation is comparatively simple and convenient.

Referring to fig. 1 to 3 in particular, in order to control the matching length of the adapter tube 2 and the tube joint body 1, the tube joint assembly provided in this embodiment further includes a blocking portion 121, the blocking portion 121 is located on a side of the second receiving portion 123 relatively far away from the tube joint abutting portion 13, in addition, in order to limit the adapter tube 2 from moving further toward the interior of the tube joint body 1 when the blocking portion 121 contacts the adapter tube 2, an orthographic projection of the blocking portion 121 along a plane where a cross section of the tube joint assembly is located and an orthographic projection of the adapter tube 2 along the plane have an overlapping portion, so that the adapter tube 2 can abut against the blocking portion 121, and when a cross section of an outer periphery of the adapter tube 2 and an inner wall of the blocking portion 121 is circular, an outer diameter of the adapter tube 2 is greater than a diameter of the blocking portion 14.
