Cause not easy to disassemble with pipe fitting tension.
Utility model content
The purpose of the utility model is to provide a kind of reliable, steady pipe fittings of connection.
Purpose of the utility model is realized as follows: a kind of pipe fitting, it is characterised in that: including interior set body and housing
Body is equipped with gum cover between interior set body and outer sleeve body, interior set body is made of the sheet body of several ring valve structures, and sheet body both ends are set respectively
There are card slot and card, connect structure in a ring between several sheet bodies, sheet body inner wall is equipped with internal screw thread, and the outer wall of sheet body is equipped with the
One positive stop strip, gum cover are equipped with the first limiting slot being adapted to the first positive stop strip, and the inner wall of outer sleeve body is equipped with the second positive stop strip,
Gum cover is equipped with the second limiting slot being adapted to the second positive stop strip.
By using above-mentioned technical proposal, it can be fixed, can also be led to by heat seal between interior set body, gum cover and outer sleeve body three
It crosses adhesive bonds, is connected by the card slot being adapted to card between adjacent pellets, pass through the first positive stop strip of adaptation and the
The setting of one limiting slot, can increase the bonding strength between sheet body and gum cover, be limited by the second positive stop strip of adaptation and second
The setting of slot, can increase the bonding strength between outer sleeve body and gum cover, when installation, in the externally threaded major diameter of pipe fitting is larger than
The major diameter of screw thread, then in use, interior set body can generate expansion or contraction with expanding with heat and contract with cold for pipe fitting, so that interior set body and pipe fitting
Connection is more stable, and resistance is small when installation or disassembly, is easy to use.
The utility model is further arranged to: the first threaded hole and second radially opened up is additionally provided on the outer sleeve body
The first through hole being connected to the first threaded hole is equipped on threaded hole, gum cover and sheet body, be connected to the second threaded hole it is second logical
Fastening screw is equipped in hole, the first threaded hole and the second threaded hole.
By using above-mentioned technical proposal, the first threaded hole and the second threaded hole are opened in the both ends of outer sleeve body respectively, and
Fastening screw is arranged radially, can be radially fixed to the two pipe fittings progress connecting with pipe fitting, is avoided between pipe fitting and interior set body
Axial play phenomenon is generated, further increases connective stability, and can ensure that its leakproofness.
The utility model is further arranged to: the both ends of the gum cover protrude from the both ends of interior set body.
By using above-mentioned technical proposal, when pipe fitting is connect with external pipe fitting, gum cover can be with the end face of external pipe fitting
It contradicts, plays direct sealing function.
The utility model is further arranged to: the sheet body is four.
By using above-mentioned technical proposal, the expansion and contraction effect of interior set body is best.
