Moreover, beam ring commonly used, its inner ring perisporium for be flat state around, therefore force and during the reduced bore when tightening in an end indentation, there of equal circumference, the squeezing action power of its inner ring peripheral wall surfaces between can't impartial dispersion tissue, cause tightening poor effect, also promptly be short of the effects such as equalization bundle of equal circumference.

The defective of above-mentioned beam ring also takes place on the primary and secondary taper.Because it is bigger that the caliber that is produced on taper primary and secondary sleeve pipe changes, as desire effectively to reach the power of tightening under different pipe fitting scopes, using traditional beam ring is very improper behave.

The purpose of this utility model provides a kind of beam ring body that can tighten effect in the big caliber than scope, absorb formed compression force between the inner ring perisporium by its packing ring that contains, improve simultaneously packing ring body itself compression and loose from the time involution intensity, the persecution of avoiding metal structure to be compressed or stretching is used in the Applicable scope and the packing effectiveness thereof of tightening on the different tube diameters thereby improve it.

The utility model is achieved in that being included in the interior group cover of beam ring packing ring constitutes, wherein a side of beam ring and packing ring is respectively equipped with short slot and breach, the short slot both sides outer wall of beam ring is provided with and is used for quick detach bolt and nut and cooperates and revolve the contract corresponding ear seat of short slot and breach on this beam ring and the packing ring of lock bundle, it is characterized in that: the ring of beam ring week internal face be provided with hollow slot around, solid for potting in the outer wall that packing ring is installed, equidistantly be provided with on the ring of the packing ring week inner ring wall serrated face around, and form grooving between each serrated face, the coherent circular groove that forms in ring body outer end in each grooving is tangent, thereby forms the beam ring body that contains packing ring.

Above-mentioned beam ring body internal face can assemble one or more packing ring simultaneously.

Characteristics of the present utility model are: be provided with the packing ring than minor diameter in larger-diameter beam ring body, make when under the certain limit caliber, utilizing bolt to tighten the beam ring body, can allow the packing ring of inner ring bear in a big way the active force of tightening, make the beam ring of outer ring bear the power of tightening of less appearance part scope relatively, thereby its working life and the solid effectiveness of bundle are provided.Another characteristics are to utilize flexuose embedding in the packing ring to touch face to go to tighten female pipe outer wall, and the power of the tightening enhancing stop that utilizes institute between packing ring outer wall and beam ring internal face contact to form tighten effect, thereby the bundle of raising beam ring body stablizing effect admittedly.Moreover the assembly unit simultaneously of beam ring inside is nested with one or more packing ring, and and allow its flexuose embedding touch the usefulness that the interlaced correspondence of face realizes the solid pipe fitting of the multi-level bundle of equal circumference.
