Abstract

The utility model relates to a pipe connecting member which can be conveniently assembled, wherein one end of an end cover (2) is connected with an outer screw thread IC at the end part of a main body member (1) through a screw thread hole, and one end of a pipe (7) extends into a conical hole 2A of the end cover (2). A conical locking ring (5) with an opening 5A is arranged between the conical hole 2A and the pipe (7), a washer (4) and two sealing rings (3) are sheathed in turn between the locking ring (5) and the end surface 1A of the butted main body member (1), wherein one of the sealing rings (3) is positioned in a ring groove 1B on the end surface of the main body member (1). The pipe connecting member of the utility model has simple structure, does not need processing screw threads on the pipe member, does not need special tools, has laborsaving and timesaving assembly and disassembly, improves construction progress, reduces cost, and is suitable for the connection of various pipes.

Description

Convenient assembling and disassembling tubing link

The utility model relates to a kind of tubing link, particularly convenient assembling and disassembling tubing link.

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, and needing wastes time and energy with special machining screw instrument and know-how.Influence construction speed.

The utility model purpose provides a kind of convenient assembling and disassembling tubing link, and it need not special machining screw instrument and know-how, and it is simple in structure, and is easy to loading and unloading quick, time saving and energy saving, quickened construction speed.

The utility model purpose realizes by following technological scheme.

Convenient assembling and disassembling tubing link, it is characterized in that: it comprises end cap 2, seal ring 3, packing ring 4, locking ring 5, 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 ends have 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, be set with packing ring 4, two seal rings 3 between locking ring 5 and the end face 1A that is docked main component 1 successively, wherein seal ring 3 is positioned to be docked among the annular groove 1B on main component 1 end face.Between described two seal rings 3 packing ring 6 is housed also.The inner face 4A of described packing ring 4 is the conical surface.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, packing ring 4 and seal ring 3 successively again, screw thread on main component 1 and end cap 2 screws this end cap 2 then, because locking ring 5 has opening 5A, and with end cap 2 are conical contacts, the power that screws is big more, locking ring more closely can be wedged 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, prevents that fluid in the pipe fitting 7 from when seal ring 3 is extruded, leaking from locking ring opening 5A.Refilling seal ring 3 purposes at pipe fitting 7 end faces is that a pair of seal ring is closely contacted, and guarantees that tube fluid does not leak.Also packing ring 6 can be housed between two seal rings 3, this packing ring 6 is complete ring-type, prevents because of rubber seal ring 3 volumes are little, and 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 to make it be difficult for deviating from.

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.Laborsaving saving time improved construction speed and quality greatly, reduces cost.Be convenient to dismounting, maintenance, use present technique can guarantee that any one pipe fitting on the pipe network, valve, water meter, gas meter when damaging, can disassemble with the shortest time, also can improve work efficiency greatly after fixing to install in the shortest time.Be applicable to the connection of all kinds of pipe fittings such as valve, threeway, water meter, gas meter etc.

Specifically introduce with embodiment below.

Fig. 1 is a linkage structure schematic representation of the present utility model to Fig. 4,

Fig. 5 is an another kind of linkage structure schematic representation of the present utility model,
