Locking apparatus for a movable carry module
View Patent ↗A locking apparatus for a movable carry module, comprises a controller using to fix the movable carry module of an electric device. The controller has a movable locking shaft normality stretch in the movable carry module, and applies to fix the movable carry module. The electric device supplies the electric power to the controller when receiving the external electric power, and then the locking shaft departs from the movable carry module, such that the movable carry module can move freely.
1. A locking apparatus for a movable carry module located in an electric device to fix the movable carry module, the movable carry module having a cavity, comprising:
a controller; and
a locking shaft movably located in the controller, the locking shaft having a roller mounted on one end thereof to facilitate moving in and out of the cavity, the locking shaft being receivable in the cavity of the movable carry module;
wherein the locking shaft is extended into the cavity of the movable carry module in a normal condition to prevent the movable carry module from moving, and the locking shaft is retracted from the cavity of the movable carry module when the electric device is connected to a power source and the controller is energized by electricity at the same time, such that the movable carry module is movable.
2. The locking apparatus of claim 1 , wherein the locking shaft is a cylindrical strut.
3. A locking apparatus for a movable carry module located in an electric device to fix the movable carry module, comprising:
a controller;
a locking shaft movably located in the controller; and
an anchor member located in the electric device corresponding to the locking shaft;
wherein the locking shaft is extended in the anchor member in a normal condition to prevent the movable carry module from moving, and the locking shaft escapes the anchor member when the electric device is connected to a power source, and the controller is energized by electricity at the same time such that the movable carry module is movable.
4. The locking apparatus of claim 3 , wherein the anchor member has a trough corresponding to the locking shaft for receiving the locking shaft.
5. The locking apparatus of claim 4 wherein the locking shaft has a roller mounted on one end thereof to facilitate moving in and out of the trough.
