The implication of Reference numeral in figure: 1-upper jaw, 2-lower jaw, the left jaw of 3-, the right jaw of 4-, 5-Zola bar, the right tie rod of 6-, the left draw back plate of 7-, the right draw back plate of 8-, 9-the first pin-and-hole, 10-the second pin-and-hole, 11-the 3rd pin-and-hole, 12-pull bar, the 13-through hole, the 14-baffle plate, 15-back-moving spring, 16-docking groove.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is done to concrete introduction.
See figures.1.and.2, ring-pressing tool of the present utility model comprises: upper jaw 1, lower jaw 2, left jaw 3 and right jaw 4 also comprise: the tie rod be symmetrical set and draw back plate, i.e. Zola's bar 5, right tie rod 6, left draw back plate 7, right draw back plate 8.Be specifically described as follows:
Left draw back plate 7 and right draw back plate 8 are all triangular in shape, three drift angle places are formed with three pin-and-holes, are respectively the first pin-and-hole 9, the second pin-and-hole 10 and the 3rd pin-and-hole 11, wherein, the first pin-and-hole 9 is hinged with the end of lower jaw 2, and the second pin-and-hole 10 is hinged with the bottom of tie rod.
Zola's bar 5 and right tie rod 6 are all elongated, and the end of upper end and upper jaw 1 is hinged.The middle part of Zola's bar 5 and right tie rod 6 is provided with pull bar 12, corresponding, and the outside of left jaw 3 and right jaw 4 all is formed with the through hole 13 slided around pull bar 12.
During use, by upper jaw 1, Zola's bar 5, right tie rod 6, left draw back plate 7, right draw back plate 8 and lower jaw 2 are hinged by utilizing pin to carry out shown in Fig. 1, pin also is set for fastening draw back plate on the 3rd pin-and-hole 11, in addition, the through hole 13 of left jaw 3 and right jaw 4 is enclosed within to the outside of pull bar 12, when both sides move draw back plate to the left and right, can drive lower jaw 2 moves down simultaneously, left/right jaw 4 is to left/right two side shiftings, thereby the opening of ring-pressing tool is magnified, wait that the position of pipe fitting/pipeline of need connecting and pipeline is to after connecting, move draw back plate to centre, the opening of ring-pressing tool can be dwindled, thereby impose on the docking pipeline and complete connection with high pressure.
