Embodiment:
Below in conjunction with specific embodiment and accompanying drawing the utility model is further specified.
See shown in Fig. 4-11, a kind of shear mechanism that limits the anglec of rotation, it is made up of scissors 1 in one and outer scissors 2 cooperations, and described outer scissors 2 inboards are provided with a special axis hole 22, and these axis hole 22 inwalls form a limiting section 221; Interior scissors 1 outside forms the axis body 12 that matches with this axis hole 22, and described outer scissors 2 cooperates with axis body 12 through axis hole 22 with interior scissors 1 and articulates, and wherein, described limiting section 221 forms with axis body 12 interferes.
Particularly, described outer scissors 2 comprises a main body 21, in main body 21 sides be provided with vertically downward consistent axis hole 22 in narrow outside wide guiding groove 23, these guiding groove 23 1 sides are formed with an inclined-plane 231.Described outer scissors 2 main bodys 21 1 ends are symmetrically arranged with a protruding axle 24, are symmetrically arranged with a draw-in groove 251,253 and location hole 261,262 along main body 21 other ends, wherein, form a projection 252,254 in the draw-in groove 251,253.Described axis hole 22 forms a described limiting section 221 with respect to the opposite side on inclined-plane 231.Described draw-in groove 251, form a lug boss 27 between 253, these lug boss 27 back sides are a groove 28.
Described axis body 12 has the plane 121 of a symmetry, and it also has cambered surface 122 symmetry and that be complementary with axis hole 22, and wherein, a cambered surface 122 sides are provided with an inclined plane 123.Scissors 1 comprises a body 11 in described, is symmetrically arranged with a rotating shaft 13 in body 11 1 ends, and overturning downwards along body 11 other ends forms a clamping part 14, and this clamping part 14 is provided with an opening.Interior scissors 1 offers an irregular circular hole in body 11 middle parts.
When assembling is used, interior scissors 1 is installed on the outer scissors 2, particularly, the axis body 12 in the interior scissors 1 is inserted in the axis hole 22 that is embedded in setting in the outer scissors 2 through the mode of malleation, help realizing the automation assembling; More specifically, the guiding groove 23 of axis hole 22 tops that the cambered surface 122 of the axis body 12 in the interior scissors 1 is provided with in outer scissors 2 is inserted and is embedded in the effect that the inclined-plane in the guiding groove 23 231 in the axis hole 22 plays guiding, can also prevent that axis body 12 breaks away from axis holes 22; After the installation, the state of axis body 12 and axis hole 22 is as shown in Figure 9.And for example shown in Figure 10; Axis body 12 has only a direction to rotate (promptly 231 direction is rotated towards the inclined-plane) in axis hole 22; When forwarding certain angle to; Interfere with limiting section 221 formation in the axis hole 22 on plane 121 in the axis body 12, and axis body 12 cannot be rotated further in axis hole 22, has played good position-limiting action.Because scissors and keycap have only a specific direction just can assemble, and above-mentioned limit can significantly reduce the installation time of scissors and keycap to, position-limiting action, reduces or has avoided the wrong risk of dress.
Certainly; The above is merely the specific embodiment of the utility model; Be not to limit the utility model practical range, all equivalences of doing according to the said structure of the utility model claim, characteristic and principle change or modify, and all should be included in the utility model claim.
