Abstract
The anti-explosion threading box of the utility model relates to the field of threading boxes. The anti-explosion threading box is composed of a box body, a box cover and threading mouths. The box body and the box cover are used in a matching manner and fixed with more than two screws. A sealing gasket is arranged between the box body and the box cover. The outer portion of the box body is provided with more than two threading mouths which are communicated with the inner portion of the box body. The outer of each threading mouth is clamped with a lap joint union nut. According to the anti-explosion threading box of the utility model, a swivel nut is added on the threading mouth on the outer portion of the original threading box, so fast installation and disassembly can be performed without rotating the threading box and the threading pipe during disassembly and installation, the threading pipe will not be damaged, and at the same time, the advantage of better sealing anti-explosion effect can be realized.
Description
Technical field
The utility model relates to PULL BOX, relates in particular to a kind of anti-explosion threading box.
Background technology
Electric appliance circuits in explosion-proof place is all arranged in penetration pipe, there is line joint to connect in PULL BOX screw socket, current PULL BOX is provided with two above screw thread port, threading pipe end is external screw thread, this connected mode need to carry out in penetration pipe or PULL BOX rotating just and reaching installation and removal object around axis, very inconvenient, especially when changing PULL BOX, penetration pipe is fixed on the carriers such as body of wall, in installation and removal time, can only be rotated and could, to the screwing and dismantling of screw socket, be easy to penetration pipe to damage PULL BOX.China Patent No.: 201320575024.0, patent name is placed in penetration pipe in interface for " bite type PULL BOX " discloses a kind of screw thread that is provided with on the outer wall of interface, use union nut to be connected the cutting ferrule of rotary squeezing nut inside with the external screw thread of interface, and then by the scheme of penetration pipe fixing seal, the process having solved in installation and removal does not need the rotation that PULL BOX and penetration pipe are carried out, but this only limited by single its effect of the mode being flexible coupling of cutting ferrule and penetration pipe, be easy to come off, bring certain hidden danger to explosion-proof work, the frequency of changing cutting ferrule is high, increased cost.
Utility model content
Of the present utility modelly be intended to for the deficiency existing in background technology, and the anti-explosion threading box proposing.
Anti-explosion threading box of the present utility model, to be formed by box body, lid and threading opening, its box body and lid are used in conjunction with and are fixed by plural screw rod, between box body and lid, be provided with sealing gasket, in box body outside, be provided with more than two the threading opening with box body internal communication, the outer end clamping kink pipe of described threading opening connects nut.
As further improvement of the utility model, the both sides that described kink pipe connects the Access Division of nut and threading opening are equipped with sealing ring.
Anti-explosion threading box of the present utility model, on the threading opening of original PULL BOX outside, increased rotating nut, in dismounting with when installing, do not need PULL BOX and penetration pipe to be rotated, can mount and dismount fast, penetration pipe, without any damage, has been strengthened to sealing, explosion-proof effect simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is rotating nut longitudinal sectional view of the present utility model.
Embodiment
Below in conjunction with accompanying drawing 1 and 2 pairs of anti-explosion threading boxes of the present utility model of accompanying drawing, be described further.
Embodiment 1
Anti-explosion threading box of the present utility model, by box body 1, lid 2 and threading opening 3 form, its box body 1 is used in conjunction with lid 2, by plural screw rod 4, be fixedly connected with, between box body 1 and lid 2, be provided with sealing gasket 5, in box body 1 outside, be provided with more than two the threading opening 3 with box body 1 internal communication, the outer end clamping of threading opening 3 kink pipe and is connect nut 6, kink pipe connects nut 6 and is provided with internal thread, described kink pipe connects nut 6 and is provided with Nei Katai for a side of internal diameter, the Nei Katai that described kink pipe connects on nut 6 engages with the wild card platform socket of threading opening 3 peripheries, during use, by rotation kink pipe, connecing nut 6 is connected with the external screw thread screw socket of penetration pipe 9 ends, in the process of installing and dismantling, only need to rotate kink pipe connects nut 6.
Embodiment 2
Anti-explosion threading box of the present utility model, to be formed by box body 1, lid 2 and threading opening 3, its box body 1 is used in conjunction with lid 2 and is fixing by plural screw rod 4, between box body 1 and lid 2, be provided with sealing gasket 5, in box body 1 outside, be provided with more than two the threading opening 3 with box body 1 internal communication, the outer end clamping kink pipe of described threading opening 3 connects nut 6.Kink pipe connects nut 6 and is provided with internal thread, during use, by rotation kink pipe, connecing nut 6 is connected with the external screw thread screw socket of penetration pipe 9 ends, in the process of installing and dismantling, only need to rotate kink pipe connects nut 6, for seal request, improve explosive-proof grade, described kink pipe connects nut 6 and is equipped with sealing ring 8 with the both sides of the Access Division 7 of threading opening 3, connect after nut 6 screwing kink pipe, 9 pairs of kink pipes of penetration pipe connect the Access Division 7 of nut 6 inside and the sealing ring 8 of both sides pushes, form box body 1 inside and penetration pipe 9 inside and become an airtight space, better realize explosion-proof effect, while installing and using, can need to select threading opening 3 quantity on box body 1 according to actual conditions, to realize straight line, connect, 90 ° of angles connect and cross etc.
