Abstract

The utility model discloses a extruded connection thin wall steel conduit provided with a packing ring and a connecting device for pipe fittings, and consists of a thin wall steel conduit, the pipe fittings connected with the thin wall steel conduit and a packing ring used for sealing arranged at the seam of the thin wall steel conduit and the pipe fittings connected with the thin wall steel conduit. The utility model has the advantages of simple structure, low cost and convenient use. A good sealing can be achieved by sleeving the packing ring at the seam of the thin wall steel conduit and the pipe fittings in a construction. The utility model provides a safe, dry and clean environment for the cable or wire inside the thin wall steel conduit and overcomes the deficiencies in the prior art effectively.

Description

Socket attaching type Steel Thin-Wall conduit and pipe connecting device with sealing ring

Technical field

The utility model relates to jockey between Steel Thin-Wall conduit and the pipe fitting, particularly be socket attaching type Steel Thin-Wall conduit and pipe connecting device with sealing ring.

Background technology

Present building trade, in the socket attaching type Steel Thin-Wall conduit line laying work, pass the specification requirement of the Steel Thin-Wall conduit of cable or electric wire, not only to meet national standard " the electric installation of GB/T14823.1-93 conduit specific (special) requirements-metal catheter ", also should meet the chief editor's of China Engineering Construction Standardization Association, be numbered: CECS 100:98, name becomes: " socket attaching type Steel Thin-Wall catheter wire pipeline construction and acceptance specification ".

As shown in Figure 1, according to afore mentioned rules, between the Steel Thin-Wall conduit 1 of prior art straight connector 3 and union elbow 4 sockets by having U type groove; When Steel Thin-Wall conduit 1 enters terminal box 8, answer a hole one pipe, Steel Thin-Wall conduit 1 is connected with terminal box 8, should adopt pawl type nut to be connected with nipple 5.In order to make cable or electric wire pass Steel Thin-Wall conduit 1 smoothly; For the good environment of a safety, drying, cleaning being provided for cable or electric wire, the following connected mode of the general employing of prior art: appear for the first time, evenly coat conducting resinl at the outer wall of Steel Thin-Wall conduit 1 termination or at the termination inwall of straight connector 3, union elbow 4, nipple 5 pipe fittings, and then Steel Thin-Wall conduit 1 termination point casing is connected in straight connector 3, union elbow 4, the nipple 5; Secondly, implementing point with specific purpose tool at the outer wall of straight connector 3, union elbow 4, nipple 5 terminations presses.

There is following deficiency in the connected mode of above-mentioned prior art: Steel Thin-Wall conduit 1 of every connection in the construction, all to evenly coat conducting resinl at its termination outer wall or at straight connector 3, union elbow 4, nipple 5 termination inwalls, if conducting resinl is coated with many, unnecessary conducting resinl is extruded during socket Steel Thin-Wall conduit 1, causes waste; If conducting resinl is coated with few, during socket Steel Thin-Wall conduit 1 sealing bad, water, mortar are as easy as rolling off a log to infiltrate the Steel Thin-Wall conduit 1 from the slit that connects, and influences the safe in utilization of cable or electric wire.In addition, it is bigger to be coated with the conducting resinl workload, the construction trouble.

Summary of the invention

The purpose of this utility model is to overcome the deficiency of above-mentioned technology, provide a kind of with seal ring seal be enclosed within Steel Thin-Wall conduit 1 and with the pipe fitting connector of its socket on socket attaching type Steel Thin-Wall conduit and pipe connecting device with sealing ring.

The technical scheme that solves the problems of the technologies described above is: a kind of socket attaching type Steel Thin-Wall conduit and pipe connecting device with sealing ring, this socket attaching type Steel Thin-Wall conduit with sealing ring comprises with pipe connecting device: Steel Thin-Wall conduit, the pipe fitting that is connected with the Steel Thin-Wall conduit are provided with sealing ring at Steel Thin-Wall conduit and its connecting tube interface and seal.

The beneficial effects of the utility model are: the utility model is simple in structure, and cost is low, and is easy to use.Need only the seal ring set in the utility model in the construction at Steel Thin-Wall conduit and pipe fitting interface, just can well above-mentioned interface be sealed, the good environment that the utility model provides a safety, drying, cleaning for cable in the Steel Thin-Wall conduit or electric wire effectively overcomes the deficiencies in the prior art.
