In figure: 1-frame, 2-handwheel, 3-rib hole I, 4-screw thread I, 5-Hollow circular beam I, 6-rib hole II, 7-circular hole, 8-gear I, 9-gear II, 10-screw thread II, 11-screw thread III, 12-cylinder, 13-round bar I, 14-round bar II, 15-Hollow circular beam II.
Embodiment
Be described in more detail below in conjunction with the technological scheme of embodiment to this patent.
Refer to Fig. 1, a kind of can thickness adjust adjustment mechanism for valve, comprise frame 1, handwheel 2, Hollow circular beam I 5, round bar I 13, round bar II 14 and Hollow circular beam II 15; Described Hollow circular beam I 5 is arranged in frame 1 by screw thread I 4, the center hole top of Hollow circular beam I 5 is rib hole I 3, bottom is the circular hole in external rib hole I 3, the lower end of described handwheel 2 is the prism coordinated with rib hole I 3, described Hollow circular beam II 15 is positioned at Hollow circular beam I 5, and upper end is also the prism coordinated with rib hole I 3; The center hole upper end of described Hollow circular beam II 15 is rib hole II 6, and bottom is also the circular hole 7 in external rib hole II 6, and described round bar I 13 is positioned at Hollow circular beam II 15, and upper end is the prism coordinated with rib hole II 6; Outside, described Hollow circular beam I 5 lower end is provided with gear II 9, and described round bar I 13 lower end is provided with screw thread II 10, and is provided with Returnning spring (easy understand, therefore not shown) between screw thread II 10 top and gear II 9, is connected bottom screw thread II 10 with valve regulated bar; Described round bar II 14 is arranged in parallel with round bar I 13, and is rotatably installed in frame 1, and round bar II 14 lower end is provided with the cylinder 12 be fixedly connected with it, is provided with the screw thread III 11 coordinated with screw thread II 10 outside cylinder 12; Round bar II 14 upper end is provided with the gear I 8 be fixedly connected with it; The height b in described rib hole I 3 is greater than the thickness of gear I 8, Returnning spring in the raw time length be greater than the height a in rib hole II 6.
Working principle of the present utility model is:
When pressing down handwheel 2, make Returnning spring be in compressive state, gear I 8 and gear II 9 depart from completely, and the prism of round bar I 13 upper end is positioned at rib hole II 6, and rib hole I 3 coordinates with the prism of handwheel 2 lower end and the prism of Hollow circular beam II 15 upper end simultaneously; Now rotation hand wheel 2 drives Hollow circular beam I 5 to rotate, Hollow circular beam I 5 drives Hollow circular beam II 15 to rotate, Hollow circular beam II 15 drives round bar I 13 to rotate, helical pitch due to described screw thread II 10 is less than the helical pitch of screw thread I 4, so round bar I 13 drives valve regulated bar to rotate, realize the coarse adjustment of valve.
Do not press down handwheel 2, when Returnning spring in the raw time, gear I 8 coordinates completely with gear II 9, and the prism of round bar I 13 upper end is all positioned at circular hole 7, still ensures that rib hole I 3 coordinates with the prism of handwheel 2 lower end and the prism of Hollow circular beam II 15 upper end simultaneously; Now rotation hand wheel 2 drives Hollow circular beam I 5 to rotate, Hollow circular beam I 5 drives Hollow circular beam II 15 to rotate, but now Hollow circular beam II 15 does not directly drive round bar I 13 to rotate, but rotated by gear II 9 actuation gear I 8, then drive round bar I 13 to rotate by screw thread III 11 and screw thread II 10; Helical pitch due to described screw thread II 10 is less than the helical pitch of screw thread I 4; So round bar I 13 drives valve regulated bar, realize the fine setting of valve.
Above the better embodiment of this patent is explained in detail, but this patent is not limited to above-mentioned mode of execution, in the ken that one skilled in the relevant art possesses, can also makes a variety of changes under the prerequisite not departing from this patent aim.
