As Figure 13-16, described damper 24, comprise shell 2401, axle 25, glue lid 26, y-shaped ring 27, rubber cushion 28, piston 29, O-ring seals 30 and Capsule 31, O-ring seals 30 is inserted in the annular groove 2903 of piston 29, damping oil quantitatively adds in the blind hole 2402 of shell 2401, the second end 2502 of axle 25 is pressed in the axis hole 2902 of piston 29, axle 25 is connected with axis hole 2902 buckles of piston 29, rubber cushion 28, y-shaped ring 27, glue lid 26 is inserted in axle 25 successively, the first end of axle 25 2501 is pressed in the Capsule blocked hole 3102 of Capsule 31, axle 25 is connected with blocked hole 3102 buckles of Capsule 31, piston 29 after installing, axle 25 assemblies pack in shell 2401, O-ring seals 30 and piston 29 can move forward and backward in shell 2401, rubber cushion 28, y-shaped ring 27, glue lid 26 is fixed in the first cannelure 2403 of shell 2401, the convex edge 2701 of glue lid 26 snaps in the second cannelure 2404 of shell 2401 carries out buckle connection.
First end 2501 and the second end 2502 of described axle 25 are respectively equipped with a circle groove, and blocked hole 1302 inner sides of the axis hole 2902 of described piston 29 and described Capsule 31 are respectively equipped with a circle flange, and described groove coordinates buckle to connect with corresponding described flange.
Described piston 29 has a small flow channels 2901, institute's small flow channels 2901 is for being parallel to the through hole of axis hole 2902, described piston 29 central column lateral walls have an annular groove 2903, along annular groove 2903 outer walls downwards until penetrate the lower edge of annular groove 2903 and parallel with axis hole 2,902 four large runners 2904 be set.
The Capsule draw-in groove 3101 of the Capsule 31 in described damper 24 snaps in the connecting axle 18 in the first centering block hole 801 that is riveted on centering block 8, carries out movable axis connection; The shell draw-in groove 2407 of damper 24 is snapped in the connecting axle 18 of the adjustment sheet connecting hole 1302 that is riveted on adjustment sheet 13, carry out movable axis connection.Can conveniently install and dismantle.
In the time that axle 25 stretches out, blind hole 2402 inwalls of the lateral wall of O-ring seals 30 and shell 2401 produce frictional force, O-ring seals 30 moves in the annular groove 2903 of piston 29, sealing between section of O-ring seals 30 and the lower cell wall 2906 of piston 29, another section of O-ring seals 30 and the upper cell wall 2905 of piston 29 produce space, the front and back oil pocket of 4 large runner 2904 UNICOM's shells 2401 of piston 29, damping oil is by a small flow channels 2901 of piston 29, 4 large runners 2904 carry out rapid flow, flow into opposite side cavity from a side cavity of piston 29, now, it is less that axle 25 moves damping,
In the time that axle 25 is return, blind hole 2402 inwalls of the lateral wall of O-ring seals 30 and shell 2401 produce frictional force, O-ring seals 30 moves in the annular groove 2903 of piston 29, section of O-ring seals 30 and the lower cell wall 2906 of piston 29 produce space, sealing between another section of O-ring seals 30 and the upper cell wall 2905 of piston 29,4 large runners 2904 of piston 29 are sealed by O-ring seals 30, damping oil can only flow at a slow speed by of piston 29 small flow channels 2901, now, to move damping larger for axle 25; The size that damper moves damping by axle 25 is controlled the return speed of cutting with scissors cup 1, thus gauge tap door speed.
In order effectively to control the speed of different phase in the process of closing the door, the inwall of the blind hole 2402 of described shell 2401 has at least one oil groove of crossing that is parallel to described blind hole 2402, the utility model arranges a short oil groove 2405 excessively and a long oil groove 2406 of crossing, and described two mistake oil grooves are arranged on one end of next-door neighbour's the first cannelure 2403.Preferably, two short oil groove 2405 and two long oil grooves 2406 of crossing crossed are set.
Now return to the innermost process of blind hole 2402 taking axle 25 by outermost and be further described as example, axle 25 is at the leading portion of returning, and the small flow channels 2901 of damping oil by piston 29, shortly crosses oil groove 2405 and grows oil groove 2406, and translational speed is very fast, damping minimum; Axle 25 is in the stage casing of returning, and crossed the short oil groove 2405 of crossing, the small flow channels 2901 of damping oil by piston 29 and grew oil groove 2406, and translational speed is slack-off; Axle 25, at the back segment of returning, has been crossed and had been grown oil groove 2406, and damping oil can only pass through a small flow channels 2901 of piston 29, and translational speed is the slowest; Thereby having realized the speed of axle 25 in the process of returning serves as reasons soon-slow-the slowest action.Duty is in contrast in the time stretching out for axle 25.
Below eccentric nail 14 is described the size adjustment of buffer damping:
When eccentric nail 14 is rotated counterclockwise dominant bit, the relative pivoted arm 4 of adjustment sheet 13 moves forward, and drives shell 2401 to move forward, axle 25 moves relative to piston 29, damper 24 back cavities become minimum, and the initial position of O-ring seals 30 was grown outside oil groove 2406 shell 2401, saw Fig. 4; When axle 25 is return, whole process only has the small flow channels 2901 of piston 29 excessively oily, the damping maximum that hinge is closed the door, and door closing speed is very slow, sees Figure 10.
When eccentric nail 14 is along being rotated counterclockwise interposition, after the relative pivoted arm 4 of adjustment sheet 13, move, after driving shell 2401, move, axle 25 moves relative to piston 29, damper 24 back cavities become large, the initial position of O-ring seals 30 crosses outside oil groove 2405 shell 2401 short, grew oil groove 2406 within, see Fig. 6; When axle 25 is return, small flow channels 2901 shells 2401 of leading portion piston 29 to grow oil groove 2406 excessively oily, speed, back segment only has the small flow channels 2901 of piston 29 excessively oily, and speed is slack-off, and the damping that hinge is closed the door in this process is large from little change, entirety door closing speed is very fast, sees Figure 11.
When eccentric nail 14 is along being rotated counterclockwise minimum bit, after the relative pivoted arm 4 of adjustment sheet 13, move, after drive shell 2401, move, axle 25 moves relative to piston 29, damper 24 back cavities become maximum, and the initial position of O-ring seals 30, within the short oil groove 2405 excessively of shell 2401, is shown in Fig. 8; When axle 25 is return, the small flow channels 2901 of leading portion piston 29 and shell 2401 short crossed oil groove 2405, to grow oil groove 2406 excessively oily, fastest, the small flow channels 2901 of stage casing piston 29 and to grow oil groove 2406 excessively oily, speed is slack-off, and back segment only has the small flow channels 2901 of piston 29, speed is slack-off, the damping that hinge is closed the door in this process becomes greatly greatly again from little change, and overall door closing speed is the fastest, sees Figure 12.
