Abstract
The utility model relates to a buried pin type pipe joint, which is characterized in that two half arc-shaped bodies are buckled for forming a pipe body, saw teeth are arranged at the end part on one side of the first arc-shaped half body, a tooth buckling groove which is used for buckling the saw teeth so as to prevent disengagement is correspondingly arranged at the end part on one side of the second arc-shaped half body, and an elastic propping piece is arranged in the tooth buckling groove for elastically propping the lower surface of the saw teeth when the saw teeth extend into the buckling groove; and at least one short pin shaft is arranged at the end part on the other side of the first arc-shaped half body, and a slot for facilitating the hinged joint and movement of the short pin shaft is correspondingly arranged at the end part on the other side of the second arc-shaped half body. The buried pipe joint is not only simple in structure, reasonable in design, convenient to produce and manufacture and low in cost, but also is convenient and fast to mount and use.
Description
Technical field:
The utility model relates to a kind of ground bolt-type pipe joint that buries.
Background technique:
At present, installation for the ease of underground cables, the use of underground pipe spare more and more frequently, also more and more widely, but underground pipe spare all has certain-length, in order on than long pipe runs, to lay underground pipe spare, between pipe fitting and the pipe fitting pipe joint must be arranged, though many pipe joints are arranged at present on the market, as the patent No. is CN02268275.9, denomination of invention is " a steel-plastic composite pipe joint ", but this pipe joint not only complex structure, manufacture that difficulty is big, cost is high, and install loaded down with trivial detailsly, waste time and energy.
Summary of the invention:
The purpose of this utility model is to provide a kind of ground bolt-type pipe joint that buries, and it is not only simple in structure, reasonable in design that this buries ground bolt-type pipe joint, and simple installation, time saving and energy saving.
The utility model buries ground bolt-type pipe joint, it is characterized in that: fasten by the two halves arc body, constitute a tubular body, the end, one side of the described first arc halfbody is provided with sawtooth, described second arc halfbody end correspondence on one side is provided with in order to fasten the buckle teeth groove that sawtooth prevents its disengagement, is provided with elasticated topsheet in the described buckle teeth groove and withstands the sawtooth lower surface with elasticity when sawtooth stretches into catching groove; The another side end of the described first arc halfbody is provided with at least one short pin shaft, and the another side end correspondence of the described second arc halfbody is provided with the slot in order to the hinged activity of short pin shaft.
The utility model buries ground bolt-type pipe joint in use, the two pipe fittings mouth of pipe that at first will dock in advance is near placing, then each short pin shaft is inserted in each slot, make this pipe joint one end hinged good, be inserted in this mouth of pipe joint, underground pipe joint two arc halfbodies close, at this moment, the sawtooth of the first arc halfbody promptly buckles into the buckle teeth groove, because elasticated topsheet is set, the elastic reaction of this elasticated topsheet helps preventing that sawtooth from deviating from, and the utility model underground pipe joint is not only simple in structure, reasonable in design, the manufacturing is convenient, cost is low, and easy to install quick.
