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. The first cylindrical shell and the second cylindrical shell respectively have a tightening port. 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. A bottom end of the cylindrical cavity forms a circular step surface, and the circular step surface is provided with antiskid projections. The end surface of one end of the second cylindrical shell, which is far from the tightening port thereof, stretches axially to form an annular sleeve. The end surface of a tail end of the annular sleeve is provided with a rubber layer. The outer periphery of the annular sleeve is provided with external threads matching with the internal threads, and thus the threaded connection between the first cylindrical shell and the second cylindrical shell is formed, thereby achieving abutting connection between the rubber layer and the antiskid projections. The threaded explosion-proof box achieves an effect of compact and reliable structure.

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 the screw-type anti-explosion box for cable middle connector that a kind of structure is compacter and 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, and the annular step surface is formed on the bottom of described cylindrical cavity, be provided with several anti-skidding projections on described annular step surface, on described the second cylindrical shell, at a distance extended axially annulus on its end end face that tightens mouthful, be provided with rubber layer on the distal end faces of this annulus, and offer the suitable external screw thread of internal thread on the inner peripheral surface with described cylindrical cavity on the outer circumference surface of described annulus, by being threaded of described internal thread and externally threaded adaptive formation the first cylindrical shell and the second cylindrical shell, and then make described rubber layer and the described anti-skidding butt that convexes to form.
Concrete, described anti-skidding projection has rectangle protuberance and wedge-shaped part, described wedge-shaped part has the lozenges that extends to described annular step surface from the top end face of described rectangle protuberance, and this lozenges bearing of trend from high to low is consistent with the precession direction of described annulus.
Concrete, described anti-skidding projection circumferentially is uniformly distributed on described annular step surface.
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 three 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, further be provided with anti-skidding projection and rubber layer on the arch steps face and form butt, because rubber layer has certain soft and elastic performance, make rubber layer and described lozenges move back the certain butt of formation on direction revolving of annulus, reach the more reliable compact effect of structure of armored cassette; 3,, 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.
