Abstract
The double-deck sound insulation tube Hermetical connecting structure, including drainpipe and groove pipe fitting, slot is formed on the inner wall of groove pipe fitting, drainpipe sleeve is in slot, annular protrusion rib is formed on the outer wall of drainpipe, drainpipe external screw thread is formed on annular protrusion rib, and groove pipe fitting external screw thread is formed on the outer wall of groove pipe fitting, sealing shroud is screwed on drainpipe external screw thread and groove pipe fitting external screw thread, and seal washer is clamped between annular protrusion rib and the upper surface or lower end surface of groove pipe fitting.It between its groove pipe fitting and drainpipe other than marine glue is tightly connected, is also tightly connected by sealing shroud and seal washer, thoroughly prevents air and enter drainpipe, prevent drainpipe from issuing loud noise.
Description
Technical field
The utility model relates to sound insulation tube technical fields, more specifically to a kind of connection knot of double-deck sound-proof drain pipe
Structure.
Background technique
CN201420396392.3 discloses a kind of double-deck sound-proof drain pipe connection accessory, its groove pipe fitting and drainpipe it
Between using sealing glue connection, the disadvantages are as follows: sealant with easy to aging after a period of time, causes groove pipe fitting and draining in this way
It is poorly sealed between pipe, lead to there is air to enter drainpipe, after air enters drainpipe, loud noise can be generated.
Summary of the invention
The purpose of the utility model is to solve the deficiencies of the prior art, and provides a kind of double-deck sound insulation tube sealed connection knot
Structure is also tightly connected by sealing shroud and seal washer between its groove pipe fitting and drainpipe other than marine glue is tightly connected,
Thoroughly preventing air enters drainpipe, prevents drainpipe from issuing loud noise.
The technology solution of the utility model is as follows:
The double-deck sound insulation tube Hermetical connecting structure, including drainpipe and groove pipe fitting form on the inner wall of groove pipe fitting slotting
Slot, drainpipe sleeve form annular protrusion rib, the row of forming on annular protrusion rib in slot on the outer wall of drainpipe
Water pipe external screw thread forms groove pipe fitting external screw thread on the outer wall of groove pipe fitting, and sealing shroud is screwed onto drainpipe external screw thread and ditch
On barrel part external screw thread, seal washer is clamped between annular protrusion rib and the upper surface or lower end surface of groove pipe fitting.
The outer diameter face of the sealing shroud is shaped to regular polygon.
The seal washer is rubber washer, and groove pipe fitting is straight coupling or concentric reducer connector or union elbow or threeway
Connector.
The utility model has the beneficial effects that:
Between its groove pipe fitting and drainpipe other than marine glue is tightly connected, also sealed by sealing shroud and seal washer
Connection, thoroughly prevents air and enters drainpipe, prevents drainpipe from issuing loud noise.

Fig. 1 is the structural schematic diagram of embodiment 1；
Fig. 2 is the structural schematic diagram of groove pipe fitting part in embodiment 1；
Fig. 3 is the structural schematic diagram of embodiment 2；
Fig. 4 is the structural schematic diagram of embodiment 3；
Fig. 5 is the structural schematic diagram of embodiment 4.
In figure: 1, drainpipe；11, annular protrusion rib；12, drainpipe external screw thread；2, groove pipe fitting；21, slot；22,
Groove pipe fitting external screw thread；3, sealing shroud；4, seal washer.
Specific embodiment:
Embodiment 1: as shown in FIGS. 1 and 2, the double-deck sound insulation tube Hermetical connecting structure, including drainpipe 1 and groove pipe fitting 2, ditch
Slot 21 is formed on the inner wall of barrel part 2,1 sleeve of drainpipe forms convex annular on the outer wall of drainpipe 1 in slot 21
Rib 11 is played, drainpipe external screw thread 12 is formed on annular protrusion rib 11, groove pipe fitting is formed on the outer wall of groove pipe fitting 2
External screw thread 22, sealing shroud 3 are screwed on drainpipe external screw thread 12 and groove pipe fitting external screw thread 22, and seal washer 4 is clamped in annular
Between raised rib 11 and the upper surface or lower end surface of groove pipe fitting 2.
The outer diameter face of the sealing shroud 3 is shaped to regular polygon.
The seal washer 4 is rubber washer, and groove pipe fitting 2 is straight coupling.
Embodiment 2, as shown in Figure 3, the groove pipe fitting 2 are concentric reducer connector or union elbow or three-way connection.Remaining
With embodiment 1.
Embodiment 3, as shown in Figure 4, the groove pipe fitting 2 are union elbow.Remaining is the same as embodiment 1.
Embodiment 4, as shown in Figure 5, the groove pipe fitting 2 are three-way connection.Remaining is the same as embodiment 1.
Working principle: sealing shroud 3 and seal washer 4 will be again sealed off between drainpipe 1 and groove pipe fitting 2, such air
It will not enter in drainpipe 1, so that thoroughly preventing air enters drainpipe, prevent drainpipe from issuing loud noise.
