Abstract
The utility model relates to a threaded explosion-proof box for an intermediate joint of a cable. The threaded explosion-proof box comprises a first cylindrical shell and a second cylindrical shell. One end of the first cylindrical shell and one end of the second cylindrical shell respectively have a tightening port, and the tightening ports have through hole through which the cable passes. One end of the first cylindrical shell, which is far from the tightening port thereof, has a cylindrical cavity formed by a reaming technology, and the inner periphery of the cylindrical cavity has internal threads. One end surface of the second cylindrical shell, which is far from the tightening port thereof, stretches axially to form a circular sleeve. The outer periphery of the circular sleeve is provided with external threads matching with the internal threads of the cylindrical cavity, and thus threaded connection between the first cylindrical shell and the second cylindrical shell is formed through the cooperation between the internal threads and the outer threads. The threaded explosion-proof box adopts thread connection to achieve tight cooperation, thereby achieving an effect of being simple in structure and low in cost.
Description
Technical field
The utility model relates to a kind of explosion-protection equipment of high-voltage cable middle joint, is specifically related to a kind of screw-type anti-explosion box for cable middle connector.
Background technology
Those skilled in the art should know, anti-explosion box for cable middle connector of the prior art generally comprises two semicylinder shells that connect, and then form the flame proof inner chamber between two semicylinder shells, yet, the anti-explosion box for cable middle connector of this kind structure is because the flange that connects is longer, and then causes the flame proof gap of interface also longer, is used in the bolt use amount of interface position locking armored cassette relatively many, and it is feasible that the distribution of bolt has no rule, and production cost is higher.
Summary of the invention
The purpose of this utility model is to overcome the defect of prior art, and a kind of simple and compact for structure and screw-type anti-explosion box for cable middle connector that can effectively reduce production costs is provided.
For achieving the above object, the utility model adopts a kind of screw-type anti-explosion box for cable middle connector, comprise the first cylindrical shell and the second cylindrical shell, a wherein end of described the first cylindrical shell and described the second cylindrical shell has respectively the mouth of tightening, the described mouth that tightens has the through hole that passes through for cable penetration, have in an end that tightens mouth the cylindrical cavity that forms by chambering process at a distance on described the first cylindrical shell, offer internal thread on the inner peripheral surface of this cylindrical cavity; On described the second cylindrical shell, at a distance extended axially annulus on its end end face that tightens mouthful, offer the suitable external screw thread of internal thread on the inner peripheral surface with described cylindrical cavity on the outer circumference surface of this annulus, and being threaded by described internal thread and externally threaded adaptive formation the first cylindrical shell and the second cylindrical shell.
Concrete, for the overall structure that makes armored cassette is compacter, the docking location of described the first cylindrical shell and described the second cylindrical shell is provided with elastic rubber layer.
Concrete, on the inwall of described the first cylindrical shell and the second cylindrical shell, the close neighbour is provided with fireprotection layer, describedly tightens close neighbour on mouthful through-hole wall at place and is provided with axial waterstop.
The utility model is by the above-mentioned improvement to prior art, reached the beneficial effect of following two aspects: 1, due to the first cylindrical shell and the second cylindrical shell directly are threaded connection and realize closely cooperating, the foreseeable use of cancelling bolt, and further simplified staff's assembly process, therefore effectively reduce production cost, improved production efficiency; 2,, owing to being provided with axial waterstop on the through-hole wall tightening the mouth place, prevented that further outside moisture from entering the armored cassette inner chamber by cable with tightening mouthful gap at place, reached fabulous block-water effect.
