Electronic device having lever with precision pivot
An exemplary electronic device includes a housing, a lever, and a locking device securing the lever on the housing. The housing includes a bottom plate, a top plate and a side plate connecting the bottom plate with the top plate. The locking device includes a nut having a main body extending downwardly into the lever, a screw extending upwardly through the top plate into the nut, and gaskets sandwiched between the top plate and the nut. The lever is disposed on the top plate and sleeved on the nut with a gap defined between a top face of the lever and a bottom face of a head of the nut. A polytetrafluoroethylene paste is provided on an interface between the nut and the screw.
1. An electronic device comprising:
a housing comprising a plate;
a lever disposed on the plate; and
a locking device comprising:
a nut downwardly inserted into the lever;
a gasket sandwiched between the nut and the plate;
a screw upwardly extending through the plate into the nut; and
a polytetrafluoroethylene paste provided at an interface between the screw and the nut;
wherein the lever is sleeved on the nut and confined between the nut and the top plate;
wherein a gap is defined between the nut and a top face of the lever so that the lever is slightly movable along a top-to-bottom direction of the locking device and rotatable about locking device; and
wherein the gasket is received within and surrounded by the lever.
2. The electronic device of claim 1 , wherein a plurality of gaskets are sandwiched between the nut and the top plate, the number of gaskets being proportional to a thickness of the lever.
3. The electronic device of claim 2 , wherein the number of gaskets is directly proportional to the thickness of the lever.
4. The electronic device of claim 1 , wherein the nut comprises a head and a main body extending downwardly from the head, the lever being sleeved on the main body of the nut.
5. The electronic device of claim 4 , wherein the head of the nut has an outer diameter larger than that of the main body of the nut.
6. The electronic device of claim 4 , wherein the gap is defined between a bottom face of the head of the nut and the top face of the lever.
7. The electronic device of claim 4 , wherein the lever has a thickness smaller than a distance between a bottom face of the head of the nut and the top face of the plate.
8. The electronic device of claim 4 , wherein the screw comprises a head and a pole extending upwardly from the head, the pole of the screw having an outer diameter smaller than that of the main body of the nut.
9. The electronic device of claim 8 , wherein the polytetrafluoroethylene paste is attached on an outer circumferential face of the pole of the screw.
10. The electronic device of claim 8 , wherein the head of the screw abuts against a bottom face of the plate.
11. The electronic device of claim 8 , wherein the pole of the screw extends through the plate and is threadedly fixed into the main body of the nut.
12. The electronic device of claim 1 , wherein the electronic device is a storage bridge bay canister.
13. The electronic device of claim 4 , wherein an outer diameter of the gasket is less than an outer diameter of the main body of the nut.
14. An electronic device comprising:
a housing comprising a plate;
a lever disposed on the plate; and
a locking device comprising:
a nut comprising a head and a main body, the main body extending downwardly into the lever;
a gasket sandwiched between the main body of the nut and the plate;
a screw extending upwardly through the plate into the main body of the nut; and
a polytetrafluoroethylene paste being provided at an interface where the nut contacts the screw;
wherein an end of the lever is confined between the head of the nut and the top plate;
wherein a distance between a top face of the plate and a bottom face of the head of the nut is larger than a thickness of the end of the lever so that the lever is freely rotatable about the main body of the nut; and
wherein the gasket is received within and surrounded by the lever.
15. The electronic device of claim 14 , wherein a plurality of gaskets are sandwiched between the main body of the nut and the plate.
16. The electronic device of claim 14 , wherein a number of the gaskets is in direct ratio to the thickness of the lever.
17. The electronic device of claim 15 , wherein each of the gaskets has a thickness smaller than that of the lever.
18. The electronic device of claim 14 , wherein the screw comprises a head and a pole extending upwardly from the head, the pole of the screw being extending through the plate and fixed within the nut, and the head of the screw abutting against a bottom face of the plate.
19. The electronic device of claim 18 , wherein the polytetrafluoroethylene paste is adhered on an outer circumferential face of the pole of the screw.
20. The electronic device of claim 14 , wherein the electronic device is a storage bridge bay canister.
