Embodiment

In order more clearly to explain the utility model, below in conjunction with accompanying drawing, the utility model is further described.

Refer to Fig. 1-3, the seal ring positioning lathe dog that the utility model provides, comprises the first semicircle assembly 11 and the second semicircle assembly 12; The first end of the first semicircle assembly 11 is provided with hook 111, the second ends and is provided with a cassette tape 112, and cassette tape 112 is provided with the evenly distributed multiple boss that tilt to first direction of a row; The first end of the second semicircle assembly 12 is provided with rotating shaft 121, the second ends and is provided with jack 122, is provided with the Ka Tai tilting to the second direction contrary with first direction in jack 122; Hook 111 catches on rotating shaft 121, and rotating shaft 121 can be in hook 111 interior rotations, and cassette tape 112 assigns in jack 122, and card decometer is lived boss.

Compared to prior art, the seal ring positioning lathe dog that the utility model provides, first catch on rotating shaft 121 by hook 111, make the first semicircle assembly 11 and the second semicircle assembly 12 hinged, then by the two latch closure on pipe fitting, finally cassette tape 112 is assigned in jack 122, seal ring positioning lathe dog is close to and is fixed on pipe fitting, can block the seal ring being positioned at equally on pipe fitting, prevent that seal ring is subjected to displacement, and then ensure sealing; Because cassette tape 112 is provided with multiple boss, Ka Tai is by coordinating from different boss, and the diameter of capable of regulating positioning lathe dog, to adapt to different pipe fittings; Ka Tai and boss tilt to two contrary directions, make cassette tape 112 can easily insert jack 122, be but not easy oppositely from jack 122, to exit, and then it are stable to ensure that two halves circular components connects, and avoids occurring loosening.

Refer to Fig. 4, in the present embodiment, the first semicircle assembly 11 and the second semicircle assembly 12 comprise respectively a top board 13, a base plate 14, a riser 15 and polylith gusset plate 16, top board 13 and base plate 14 are parallel to each other, the top of riser 15 is fixed on the inner side of top board 13, the bottom of riser 15 is fixed on the inner side of base plate 14, and polylith is reinforced riser 15 and is fixed on uniformly between top board 13 and base plate 14.

The first semicircle assembly 11 and the second semicircle assembly 12 are not all solid constructions, but have adopted frame structure, have not only saved production raw material, and have improved the pliability of assembly, make positioning lathe dog can better be attached at pipe fitting outer wall.

In addition, this case is also provided with anti-skidding striped in the inner side of riser 15, and anti-skidding striped can increase frictional force between positioning lathe dog and pipe fitting, makes positioning lathe dog be not easy to slide on pipe fitting, therefore can play good locating effect to seal ring.

Refer to Fig. 5 and Fig. 6, in the present embodiment, the first end of the first semicircle assembly 11 is divided into the first top layer 113, the first mesosphere 114 and the first bottom 115, the first top layer 113 is identical with the length of the first bottom 115, the length in the first mesosphere 114 is greater than the length of the first top layer 113, wherein the first top layer 113 and the first bottom 115 are arc bump, and the first mesosphere 114 is along the outward extending hook 111 of first end, and hook 111 end is smooth circular-arc; The first end of the second semicircle assembly 12 is divided into the second top layer 123, the second mesosphere 124 and the second bottom 125, the second top layer 123 is identical with the length of the second bottom 125, the length in the second mesosphere 124 is less than the length of the second top layer 123, wherein the second top layer 123 and the second bottom 125 are the arc bump that stretches out along the second end, and rotating shaft 121 is fixed between the second top layer 123 and the second bottom 125; The end in the second mesosphere 124 is smooth circular-arc.
