Apparatus for positioning flipping cover relative to base and casing utilizing the same
An apparatus, for positioning a flipping cover relative to a base, includes a first member being fixed relative to the flipping cover, and a second member being fixed relative to the base. The first member defines an arched guiding channel around a rotating axis of the flipping cover. The first member forms at least one raised ridge extending into the guiding channel. The second member forms a guiding rod parallel to the rotating axis. The guiding rod is slidably received in the guiding channel. The guiding rod is deformable to get through the at least one raised ridge. A casing utilizing the above apparatus is also disclosed.
1. A casing, comprising:
a base;
a flipping cover pivotably attached to the base, the flipping cover being rotatable around a rotating axis;
a first member fixed to the flipping cover, the first member defining a guiding channel around the rotating axis, the first member forming at least one raised ridge extending into the channel to narrow a width of the channel adjacent an end thereof; and
a second member fixed to the base, the second member comprising a split knob slidably received in the guiding channel, the split knob being elastically deformable to pass through a part of the guiding channel where the at least one raised ridge lies.
2. The casing as claimed in claim 1 , wherein the split knob is circular rod with a hollow therein, and the split knob is deformable toward the hollow.
3. The casing as claimed in claim 1 , wherein the second member is made of polyformaldehyde material.
