Description

The fast assembling-disassembling pipe connector

Affiliated technical field

The utility model relates to a kind of fast assembling-disassembling pipe connector of fast assembling-disassembling pipe connector, particularly easy disassembly.

Background technique

Traditional metallic conduit such as waterpipe, gas pipeline etc., being connected of each pipe fitting and main component such as water meter, gas meter valve, water nozzle etc. all need be manufactured screw thread at the scene, needs special machining screw instrument and know-how, wastes time and energy, and influences construction speed.

Summary of the invention

The purpose of this utility model provides a kind of pipe connector of fast assembling-disassembling.

The purpose of this utility model is to realize like this, a kind of fast assembling-disassembling pipe connector, end cap (2) one ends link to each other with the outside thread 1C of tapped hole with the end of the main component (1) that is docked, end cap (2) the other end has taper hole 2A, one end of the pipe fitting (7) that is docked extend in this taper hole 2A, the cone locking ring (5) of band opening 5A is housed between taper hole 2A and pipe fitting (7), between locking ring (5) and the end face 1A that is docked main component (1) packing ring (4) is housed successively, two seal rings (3), wherein a seal ring (3) is positioned at by among the annular groove 1B on butt joint main component 1 end face, packing ring (6) also is housed between described two seal rings (3), and the inner face 4A of described packing ring (4) is the conical surface.

In sum, the utility model adopts the locking ring of band opening to compress, the rubber seal sealing, and between two seal rings, add a packing ring again and seal, structure is greatly simplified, during installation, do not need machining screw on the pipe fitting, without specialized tool, do not need know-how yet, bring great convenience for numerous installers and user.

Description of drawings

Fig. 1 is a linkage structure schematic representation of the present utility model;

Fig. 2 is the A-A sectional view.

Code name among the figure: 1, main component; 2, end cap; 3, seal ring; 4, packing ring; 5, locking ring; 6, packing ring; 7, pipe fitting; 1A, end face; 1B, annular groove; 1C, outside thread; 2A, taper hole; 4A, the conical surface; 5A, opening.

Embodiment

As shown in Figure 1, when using, on the end face of the main component (1) that is docked, process an annular groove 1B earlier, in this annular groove 1B, embed a rubber seal (3), at the first suit upper end cap (2) of connected pipe fitting (7) one ends, suit locking ring (5) successively again, packing ring (4) and seal ring (3), screw thread on main component (1) and end cap (2) screws this end cap (2) then, because locking ring (5) has out 5A, and with end cap (2) be conical contact, the power that screws is big more, locking ring can be wedged more closely between end cap (2) and the connected pipe fitting (7) more, be connected as a single entity thereby make pipe fitting (7) and be connected main component (1), packing ring (4) is unnotched annulus, can remedy locking ring (5) owing to have the deficiency of opening 5A, prevent the fluid seal ring (3) when being extruded again in the pipe fitting (7), leak from locking ring opening 5A, refilling a last seal ring (3) purpose at pipe fitting (7) end face is that a pair of seal ring is closely contacted, guarantee the leakage of tube fluid portion, packing ring (6) also can be housed between two seal rings (3), this packing ring (6) is complete ring-type, prevent because of rubber seal ring (3) volume little, sealing incessantly interface is provided with, make single soft seal ring (3) about two sides be the material of hard material, help sealing when compressing, the inner face 4A of packing ring (4) is the conical surface, and this conical surface helps the sealing of seal ring (3) to compress when fastening it should not be deviate from.

Claims (3)

1, fast assembling-disassembling pipe connector, end cap (2) one ends link to each other with the outside thread (1C) of tapped hole with the end of the main component (1) that is docked, end cap (2) the other end has taper hole (2A), it is characterized in that: the cone locking ring (5) that band opening (5A) is housed between taper hole (2A) and pipe fitting (7), between locking ring (5) and the end face (1A) that is docked main component (1) packing ring (4), two seal rings (3) are housed successively, wherein a seal ring (3) is positioned at by in the annular groove (1B) on butt joint main component (1) end face.

2, fast assembling-disassembling pipe connector according to claim 1 is characterized in that: packing ring (6) also is housed between two seal rings (3).

3, fast assembling-disassembling pipe connector according to claim 1 is characterized in that: the inner face (4A) of packing ring (4) is the conical surface.
