As shown in FIGS. 1-2 , the opening and closing gear 110 of the present invention includes a gear main body part 111 and a gear missing part 112 . The specific preferred structure of the gear main body part 111 is shown in FIGS. 3-4 , and the specific preferred structure of the gear missing part 112 is shown in FIGS. 3-4 . The structure is shown in Figures 5-6. The gear main body 111 is provided with a first radial through groove 114 penetrating from the gear center hole 113 to the outer edge of the gear, for the cable to pass through, that is, the cable can enter the gear center hole 113 laterally, thereby opening and closing The gear 110 can be suspended from the cable by means of the first radial through slot 114 . The gear missing portion 112 is hinged to the gear main body portion 111 at the outer port of the first radial through groove 114, so that the outer port of the first radial through groove 114 can be closed or opened. Gear teeth are processed on the gear 112 , and in the closed state, the gear missing portion 112 can make up for the missing gear teeth at the outer port of the first radial through groove 114 on the gear main body portion 111 .

As shown in FIG. 4 , on the gear main body portion 111 , at the two edges of the outer port of the first radial through groove 114 , a first axial recessed portion 115 and a second axial recessed portion are respectively provided 116 , the first axial recessed portion 115 and the second axial recessed portion 116 are formed, for example, by milling the corresponding parts of the gear main body portion 111 by about half of the thickness.

As shown in FIGS. 1-2 , the first end portion 101 of the missing gear portion 112 is pivotally accommodated in the first axial recessed portion 115 , and is connected to the gear main body portion through a first pivot shaft 117 . 111 is hinged, and when the gear complement part 112 is closed, the second end 102 of the gear complement part 112 is accommodated in the second axial recess 116, and passes through the second axial recess The side wall of the portion 116 is limited, and the first end portion 101 can also be limited by the side wall of the first axial recessed portion 115 .

As shown in FIG. 2 , at the positions of the first axial recessed portion 115 and the second axial recessed portion 116 , the gear teeth on the gear main body portion 111 and the gear teeth on the gear missing portion 112 The teeth form butt joints in the axial direction (that is, the direction of the tooth width of the gear), and together they form a complete tooth width.

As shown in FIG. 2 and FIG. 6 , among the gear teeth on the gear missing portion 112 , except at the positions of the first axial recessed portion 115 and the second axial recessed portion 116 (that is, the first axial recessed portion 116 ) Except for the gear teeth on the one end portion 101 and the second end portion 102 ) and the gear teeth on the gear main body portion 111 in the axial direction, the tooth width of the remaining gear teeth is equal to the complete tooth width after splicing. That is, in the state where the gear complement part 112 is closed, all the gear teeth of the whole opening and closing gear 110 have the same tooth width.

The above structure of the opening and closing gear 110 of the present invention ensures the precision of the gear teeth at the splicing position, and at the same time ensures the consistency of the tooth widths of the gears, thereby ensuring the meshing of the opening and closing gear 110 with the corresponding pinion.

Wherein, the thickness of the region close to the radially outer side is consistent with the overall thickness of the opening and closing gear 110 , so as to ensure the uniformity of the width of the gear teeth throughout the gear. The reduced thickness of the region near the radially inner side provides additional space for the installation of restoring elements such as torsion springs. For example, the opening and closing gear 110 may further include a torsion spring (not shown), and a part of the torsion spring may be arranged in a region near the radially inner side of the intermediate portion 103 so as to fill the missing portion 112 to the gear. A restoring force biased toward the closed position is provided, thereby preventing accidental opening of the gear complement 112 in the closed state.
