Referring to fig. 1, a pipe coupling assembly is disclosed in the present embodiment, and the pipe coupling assembly includes a pipe body 100 and a locking mechanism. Wherein, the locking mechanism is arranged at the periphery of the interface of the pipe body 100, plays a main role in connecting the pipe body 100 and the external connecting pipe 200, and realizes the sealing between the pipe body 100 and the connecting pipe 200 through the locking mechanism.
Specifically, the locking mechanism includes a fastening member 400 and a locking ring 300, and the locking ring 300 is movably sleeved on the outer circumference of the pipe body 100, that is, the locking ring 300 can move relative to the pipe body 100, and in this application, the locking ring 300 can move along the axial direction of the pipe body 100 and can rotate relative to the pipe body 100 along the axial direction.
The abutting member 400 is disposed between the outer wall of the tube body 100 and the inner wall of the locking ring 300, and at least a part of the abutting member 400 can move relative to the tube body 100, that is, a part of the abutting member 400 can be fixed relative to the tube body 100, another part of the abutting member 400 can move relative to the tube body 100, or the whole abutting member 400 can move relative to the tube body 100, in short, the part of the abutting member 400 can move and extend to the outer periphery of the nozzle of the connecting tube 200, so as to provide a foundation for the subsequent locking ring 300 to lock the tube body 100 and the connecting tube 200.
The abutting piece 400 can be connected with the inner wall of the locking ring 300 through threads, namely, the inner wall of the locking ring 300 is provided with internal threads, the surface of the abutting piece 400 facing the locking ring 300 is provided with external threads, and the internal threads are matched with the external threads. Since the fastening member 400 is movable relative to the tube body 100, the locking ring 300 is actively engaged with the fastening member 400.
In a case where the nozzle of the connection pipe 200 is fitted around the outer circumference of the nozzle of the pipe body 100, the portion of the stopper 400 can move to the outer wall of the nozzle of the connection pipe 200. That is, when a movable portion of the fastening member 400 moves to the outer wall of the nozzle of the connecting tube 200, a portion of the fastening member 400 is located on the outer wall of the nozzle of the connecting tube 200, and another portion of the fastening member 400 is located on the outer wall of the interface of the tube body 100, and then the locking ring 300 rotates relative to the tube body 100, and the locking ring 300 is in threaded engagement with the fastening member 400, so as to achieve the connection between the locking ring 300 and the fastening member 400.
In the locking process, due to the fact that the locking ring 300 and the abutting piece 400 are in threaded fit, the locking ring 300 applies abutting force to the abutting piece 400, and meanwhile, the abutting piece 400 applies abutting force to both the pipe orifice of the connecting pipe 200 and the interface of the pipe body 100 which are in contact with the abutting piece 400, so that the pipe orifice of the connecting pipe 200 is fixed relative to the abutting piece 400, the interface of the pipe body 100 is also fixed relative to the abutting piece 400, the pipe orifice of the connecting pipe 200 and the interface of the pipe body 100 are also fixed relative to each other, connection is achieved, and the process can be completed manually without the aid of other tools.
Moreover, since the pipe orifice of the connecting pipe 200 is sleeved on the periphery of the interface of the pipe body 100, the inner wall of the pipe orifice of the connecting pipe 200 can extrude the pipe body 100 while the abutting piece 400 exerts abutting force on the pipe orifice of the connecting pipe 200, so that the gap between the inner wall of the pipe orifice of the connecting pipe 200 and the outer wall of the interface of the pipe body 100 is reduced, the connection relationship between the two is tighter, the sealing effect is also improved, and liquid leakage is avoided.
It should be noted that the tightening member 400 has a certain deformation capability, that is, a small deformation occurs while receiving the tightening force from the locking ring 300, so that a tightening force can be applied to the connection pipe 200 and the pipe body 100 while the deformation occurs.
In this embodiment, the entire retaining member 400 is movable relative to the tubular body 100, and a portion of the retaining member 400 contacts the outer wall of the tubular body 100. That is, the fastening member 400 is a part separated from the tube 100, and the fastening member 400 is separated from the tube 100, so that the fastening member 400 can move integrally relative to the tube 100. Before the locking ring 300 is tightened, the tightening member 400 can integrally move relative to the pipe body 100; during the process of tightening the locking ring 300, a portion of the tightening member 400 is in close contact with the outer wall of the pipe body 100, and another portion of the tightening member 400 is in close contact with the outer wall of the pipe orifice of the connection pipe 200.
Therefore, the position of the abutting piece 400 relative to the pipe body 100 can be adjusted according to needs and connection conditions, and the abutting piece 400 is screwed through the locking ring 300 when being adjusted to a proper position, so that the application range is wide.

Specifically, a part of the fastening member 400 and the outer wall of the pipe body 100 may be fixedly connected by welding, bonding, or the like, but other connection methods may also be adopted. In this way, a portion of the fastening member 400 is connected to the outer wall of the tube body 100, and another portion of the fastening member 400 is in close contact with the outer wall of the tube opening of the connection tube 200 during the tightening process of the locking ring 300.

Specifically, any two adjacent strip-shaped structural members may be connected to each other, so that a plurality of strip-shaped structural members form an integral component, and of course, each strip-shaped structural member may be movably disposed, and any two strip-shaped structural members have no connection relationship therebetween, that is, each strip-shaped structural member can move relative to the pipe body 100.
With such an arrangement, a part of the fastening member 400 can be more easily and movably extended to the outer wall of the connection pipe 200 through the strip-shaped structure; moreover, a gap exists between two adjacent strip-shaped structural members, and in the tightening process of the locking ring 300, each gap provides a buffer space for the micro deformation generated by the extrusion of the strip-shaped structural member, so that the smooth tightening process is ensured.
In this embodiment, each of the strip-shaped structural members is a sheet, so the strip-shaped structural member includes a first side and a second side which are oppositely disposed, wherein the first side faces away from the outer wall of the tube 100, the second side faces toward the outer wall of the tube 100, the external thread is disposed on the first side, and the second side is connected to the outer wall of the tube 100.
Specifically, in the case where the strip-shaped structural member is movable integrally with respect to the pipe body 100, before the locking ring 300 is tightened, a portion of the second side surface is in contact with the outer wall of the pipe body 100, and another portion of the second side surface is in contact with the outer wall of the connection pipe 200; in a case where a portion of the bar-shaped structural member is fixed with respect to the tube body 100, a portion of the second side surface is fixedly connected to the outer wall of the tube body 100, and another portion of the second side surface is in contact connection with the outer wall of the connection tube 200.
With this configuration, the contact area between the locking ring 300 and the fastening member 400, between the fastening member 400 and the connection pipe 200, and between the fastening member 400 and the pipe body 100 is increased by the sheet structure, so that the connection pipe 200 and the pipe body 100 can be locked more easily.
Of course, in other embodiments, the fastening member 400 may not be provided with a strip-shaped structure, but may be provided with other structures as long as it can be connected with the outer wall of the pipe body 100 and the outer wall of the connection pipe 200 and is in threaded fit with the locking ring 300.
In the present embodiment, the fastening member 400 is a plastic structural member. Specifically, the plastic structural member is a member that allows a certain amount of bending deformation, and can be deformed without destroying its original performance by a force. Alternatively, the retaining member 400 may be made of plastic.
In this way, when the locking ring 300 is tightened on the pipe body 100, the biasing member 400 is deformed by a certain amount to easily apply a biasing force to the connection pipe 200 and the pipe body 100, thereby fastening the connection pipe 200 and the pipe body 100.

Therefore, the interface of the tube body 100 and the nozzle of the connection tube 200 can be directly in butt-sleeve connection, the connection tube 200 is deformed by the extrusion, and the inner diameter of the connection tube 200 is enlarged, so that the tube body 100 extends into the connection tube 200, and the contact connection between the outer wall of the interface of the tube body 100 and the inner wall of the nozzle of the connection tube 200 is realized.
In a further aspect, the pipe coupling assembly includes a beveled flange 500, the beveled flange 500 being disposed on the pipe body 100.

Since the first contact surface and the second contact surface are respectively perpendicular to the axial directions of the two pipe sections, the planes of the two contact surfaces intersect, which means that the directions of the axial directions of the two pipe sections also intersect. In a state where one of the pipe sections is horizontally disposed and the other pipe section is obliquely disposed with respect to the pipe section, one of the two ports of the pipe body 100 is located at a higher position than the other port.
