Among the figure: 1, partly press from both sides mother set, 1a, arc surface, 1b, plane, 1c, square groove, 1d, circle flange, 2, half chuck, 2a, earrings, 2b, flange, 3, cuff, 4, the half-nut cover, 5, screw, 6, torsion spring, 7, bearing pin, 8, the threaded stem axle.
Embodiment
Be connected to embodiment below by the present invention for the threaded piston rod of rear shock absorber of motorcycle and clamp of sensor, and by reference to the accompanying drawings, technological scheme of the present invention be described in further detail.
Embodiment:
Fig. 1 for this device at the tomograph at notconnect state, comprise half folder mother set 1, half chuck 2, cuff 3, half-nut cover 4, torsion spring 6, bearing pin 7; When cuff 3 being pushed into when top, under the effect of torsion spring 6, half chuck 2 separates two half-nuts covers 4 around the rotation of bearing pin 7.
Fig. 2 is the two-dimensional structure figure when to be connected of this device, has represented the internal structure of Fig. 1, and the internal thread that the threaded stem axle 8 that will need to connect is delivered to the half-nut cover 4 in the half folder mother set 1 is adjacent to the position.
Fig. 3 be this device with the two-dimensional structure figure of piston rod coupled condition, cuff pushed away for 3 times make half chuck 2 and partly press from both sides mother set 1 and close up, half-nuts cover 4 in half chuck 2 is adjacent to screw thread on the threaded stem axle 8 with the half-nut cover 4 that partly presss from both sides in the mother set 1, realizes connecting.At this moment, because the banding effect of cuff 3, so that coupled condition is kept.Partly pressing from both sides mother set 1 upper end tapped hole is connected with the power sensor and can experiences the threaded stem axle 8 stressed variation that passes.
Fig. 5 is the A-A sectional view of Fig. 4, and two of half chuck 2 earrings 2a are positioned at the square groove 1c formation Spielpassung of half folder mother set 1 among the figure, are inserted in torsion spring 6 in the space between two earrings 2a, by bearing pin 7 will partly press from both sides mother set 1, half chuck 2 is in the same place with the torsion spring pin joint.Two external parts of torsion spring are resisted against respectively on the inner hole wall of half folder mother set 1 and half chuck 2, and it automatically springs open the effect of half chuck 2 after moving on the cuff 3.
The effect of partly pressing from both sides the round flange 1d on the mother set 1 is to provide spacing to moving on the cuff 3, and the flange 2b of half chuck 2 moves down cuff to provide spacing, guarantees that cuff 3 does not break away from operation interval.During assembling, cuff 3 is inserted in by partly pressing from both sides mother set 1 lower end before carrying out pin joint half-and-half pressing from both sides mother set 1 and half chuck 2, cuff 3 can not drop out with regard to being limited between round flange 1d on the half folder mother set 1 and the flange 2b on half chuck 2 behind the pin joint like this.
Working procedure: on push away cuff 3 half chuck 2 strutted under torsion spring 6 effect, the half-nut that threaded stem axle 8 is close in the half folder mother set 1 overlaps 4, push away down cuff 3 the half-nut cover 4 in half chuck 2 is closed up with another half-nut cover 4 that partly presss from both sides in the mother set 1, finish connection.When unclamping, on push away cuff 3, under torsion spring 6 effect, half chuck 2 struts around bearing pin 7, takes out threaded stem axle 8, realizes separating.
Because it is complicated partly to press from both sides the structure of mother set 1 and half chuck 2, the section's fractal areas such as arc surface 1a, plane 1b that partly press from both sides on the mother set adopt wire cutting machine tool processing.The size of the tapped hole by conversion half-nut cover 4 can adapt to the variation of different threaded stem axle 8 diameters of thread within the specific limits.
