Abstract
A locking device includes a first side plate and a first driven screw. The first side plate includes a first moving track with a first driving member extending along the first moving track and a first driven screw includes a first threaded rod; and a first follower mounted to an end of the first threaded rod and coupling with the first driving member. When the first driven screw moves along the first moving track, the first follower is driven to rotate by the first driving member, thereby driving the first threaded rod to rotate along a locking direction or an unlocking direction. An enclosure is further disclosed.
Claims12
A locking device comprising:
- a first locking unit comprising:
- a first side plate defining a first moving track, the first side plate comprising a first rack located on a side of the first moving track and extending along the first moving track;
- a first driven screw comprising:
- a first threaded rod;
- and
- a first gear engaged with the first rack and mounted to an end of the first threaded rod and coupling with the first rack;
- a first pin flexibly connected to an end surface of the first gear;
- and
- a first spring, wherein the end surface of the first gear defines a first sink hole, an end of the first pin is connected to the first sink hole by the first spring;
- and
- a first locating plate mounted to a peripheral surface of an end of the first moving track, the first locating plate comprising a first locating hole;
- and
- wherein the latching member is coupled with the first locating hole of the first locating member;
- when the first driven screw moves along the first moving track, the first gear is driven to rotate by the first rack, thereby driving the first threaded rod to rotate along a locking direction or an unlocking direction;
- and when the first driven screw moves to a locking position along the locking direction, the first locating plate latches the first pin through the locating hole, and when the first pin is released from the locating hole, the first gear is capable of being driven to move along the unlocking direction to an unlocking position.
An enclosure comprising:
- a chassis;
- and
- a locking device located within the chassis and mounted to the chassis, comprising:
- a first locking unit comprising:
- a first side plate defining a first moving track, the first side plate comprising a first rack located on a side of the first moving track and extending along the first moving track;
- a first driven screw comprising:
- a first threaded rod;
- and
- a first gear engaged with the first rack and mounted to an end of the first threaded rod and coupling with the first rack;
- and
- a first pin flexibly connected to an end surface of the first gear;
- and
- a first spring, wherein the end surface of the first gear defines a first sink hole, an end of the first pin is connected to the first sink hole by the first spring;
- and
- a first locating plate mounted to a peripheral surface of an end of the first moving track, the first locating plate comprising a first locating hole;
- and
- wherein the latching member is coupled with the first locating hole of the first locating member;
- when the first driven screw moves along the first moving track, the first gear is driven to rotate by the first rack, thereby driving the first threaded rod to rotate along a locking direction or an unlocking direction;
- and when the first driven screw moves to a locking position along the locking direction, the first locating plate latches the first pin through the locating hole, and when the first pin is released from the locating hole, the first gear is capable of being driven to move along the unlocking direction to an unlocking position.
