Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Referring to figs. 1 through Fig. 3: elevator stock lifting control mechanism, comprise cam gear 1, inhibiting device 2 and torsion spring 3, cam gear 1 comprises cam 11 and turning cylinder 12, cam 11 is located on stock 4, turning cylinder 12 is fixedly connected with cam 11, and torsion spring 3 is set on turning cylinder 12, and inhibiting device 2 is corresponding with turning cylinder 12 to be arranged, namely inhibiting device 2 can realize turning cylinder 12 spacing, rotates after preventing turning cylinder 12 from turning to respective angles.When the production and application of reality, in order to ensure that this elevator stock lifting control mechanism can better make stock 4 be fixed on the cross bar of raising legs 7, multiple cams device 1, inhibiting device 2 and torsion spring 3 can be set, improve safety performance when using.
Cam gear 1 also comprises cam holder 13, and cam 11 and turning cylinder 12 are all located on cam holder 13, and turning cylinder 12 is erected on cam holder 13, and cam holder 13 is fastened by bolts and is arranged on stock 4.
Cam gear 1 also comprises flat key 14, turning cylinder 12 is fixedly connected with by flat key 14 with cam 11, and one end of flat key 14 embeds in turning cylinder 12, and the other end embeds in cam 11, ensure that turning cylinder 12 keeps being fixedly connected with cam 11, when turning cylinder 12 is rotated, be with moving cam 11 to rotate.
As shown in Figure 3 and Figure 5, inhibiting device 2 comprises spring 21 and locating part 22, locating part 22 is steel ball, spring 21 is located on cam holder 13, and locating part 22 is located at one end of spring 21, turning cylinder 12 offers the groove 5 matched with locating part 22, groove 5 is corresponding with locating part 22 to be arranged, namely, when groove 5 turns to locating part 22 place place, one end of locating part 22 falls into groove 5 and is blocked by turning cylinder 12, prevents it to be rotated further.
Inhibiting device 2 also comprises spring perch 23, and cam holder 13 offers mounting groove, and spring perch 23 is set in mounting groove, and fixing, and the other end and the spring perch 23 of spring 21 abut against.
