Detailed description of the invention
Below in conjunction with accompanying drawing 1-5, the utility model is described in further detail.
As shown in drawings, this utility model is primarily of elevator base 1, elevator upper cover 2, dental lamina 3, opening gear 4, gear 5, bearing 6, bevel pinion 7, motor 8, tail ring 9, bevel gear shaft 10, bevel gear wheel 11, slips 12, slip spider 13, duplicate gear 14, tooth bar 15, double crosslinking gear shaft 16, bearing pin 17, safety door 18, spring 19, stop screw 20, hold-down screw 21 forms, described motor 8 is with being fixed on elevator base 1 rear end, bevel pinion 7 to be arranged on motor 8 and to coordinate with bevel gear wheel 11, bevel gear wheel 11 is linked together by bevel gear shaft 10 and gear 5, bearing 6 is equipped with at bevel gear shaft 10 two ends, gear 5 coordinates with the external tooth of opening gear 4, opening gear 4 is arranged in the arc orbit of elevator base 1, the internal tooth of opening gear 4 coordinates with the upper end of duplicate gear 14, the lower end of duplicate gear 14 connects tooth bar 15, tooth bar 15 leading portion is fixed together by screw and slip spider 13 and is arranged in the rectilinear orbit of elevator base 1 opening both sides, slips 12 is arranged in the wedge track of slip spider 13, slips 12 is equipped with dental lamina 3, spring 19 is housed between slips 12 bottom and slip spider 1, tooth bar 15 and the duplicate gear 14 opposed open center line of described the utility model split shed both sides are asymmetric installation.
