Case fastening device
The present invention discloses a case fastening device, which is applied to a case. The handle and the plate member are respectively pivotally coupled to two ends of the base by a first pivotal element and a second pivotal element, and rotatable above the base. Two ends of the metallic buckle are respectively snap-fitted to the handle and the plate member. The bayonet bolts are fixed on the plate member. While the user presses down the handle, the metallic buckle actuates the plate member to rotate above the base, and let the-bolts be inserted into the second through-hole of the base and the first through-hole of the case, whereby the bayonet bolts are mounted to the case. While the user lifts up the handle, the bolts are withdrawn from the first through-hole and the second through-hole, whereby the bolts are dismounted from the case.
1. A case fastening device, which is applied to a case having at least a first through-hole, comprising
a base having at least a second through-hole corresponding to said first through-hole of said case;
a handle pivotally coupled to said base, so that said handle rotates above said base, and having two snap-fit holes;
a plate member pivotally coupled to said base, so that said plate member rotate above said base, and having a snap-fit element and at least a third through-hole corresponding to said first through-hole and said second through-hole;
a metallic buckle having two ends respectively snap-fitted to said snap-fit holes and said snap-fit element, and cooperating with a first pivotal element and a second pivotal element to actuate said handle and said plate member to rotate simultaneously above said base; and
at least a bolt inserted into said third through-hole and fixed to said plate member, wherein said handle is pressed down to drive said metallic buckle to actuate said plate member to rotate above said base and control said bolt to pass through said second through-hole and enter said first through-hole whereby said bolt is mounted to said case, or wherein said handle is lifted up to drive said metallic buckle to actuate said plate member to rotate above said base and control said bolt to withdraw from said first through-hole and said second through-hole whereby said bolt is dismounted from said case.
2. The case fastening device according to claim 1 , wherein two ends of a bottom of said base are extended upright to form two first lateral sides and two second lateral sides, and wherein said two first lateral sides respectively have first pivotal holes, and wherein said two second lateral sides respectively second pivotal holes, and wherein two edges of a bottom of said handle are extended downward to form two third lateral sides, and wherein said two third lateral sides respectively have third pivotal holes corresponding to said first pivotal holes, and wherein said first pivotal element is inserted through said first pivotal holes and said third pivotal holes to pivotally couple said handle to said base, and wherein two edges of a bottom of said plate member are extended downward to form two fourth lateral sides, and wherein said two fourth lateral sides respectively have fourth pivotal holes, and wherein said second pivotal element is inserted through said second pivotal holes and said fourth pivotal holes to pivotally couple said plate member to said base.
3. The case fastening device according to claim 2 , wherein said snap-fit holes respectively located on said two third lateral sides, and wherein a given distance exists between said third pivotal hole and said snap-fit hole.
4. The fastening device according to claim 1 , wherein said handle has an operation element, which is pressed down or lifted up to control said switch member to rotate above said base.
5. The case fastening device according to claim 1 , wherein said case includes at least a installation member, and wherein two ends of said installation member respectively have a first locking hole and a fastening element, and wherein said first locking hole is corresponding to a second locking hole of said base, and wherein a locking element is driven through said first locking hole and said second locking hole, and said fastening element is fastened to a fastening hole of said base, to secure said base to said case.
6. The case fastening device according to claim 1 , wherein said case is an optical disk drive case able accommodate at least a optical disk drive, and wherein said optical disk drive has at least a bolt hole corresponding to said first through-hole, and wherein said bolt is inserted through said second through-hole and said first through-hole into said bolt hole to secure said optical disk drive to said case.
7. The case fastening device according to claim 1 , wherein said case is a storage box having a container and a cover connected with said container, and wherein said cover has at least a bolt hole corresponding to said first through-hole, and wherein said bolt is inserted through said second through-hole and said first through-hole into said bolt hole to secure said cover to said container.
8. The case fastening device according to claim 1 , wherein said snap-fit element is a bent metallic plate, and wherein two ends of said metallic buckle are respectively snap-fitted to said snap-fit holes and said bent metallic plate, and wherein said snap-fit holes and said bent metallic plate have allowances for movement of said metallic buckle.
