Abstract

A locking structure for securing an electronic device includes a body, a worm shaft, a guide rod, a fixing base and a linkage set. When a user wants to connect the electronic device to another device, the user could insert the electronic device into the locking structure which is set on the device. Then, the user pushes down the electronic device to drive the locking structure and the worm shaft of the locking structure would be rotated from a releasing direction to a securing direction. When the user wants to release the electronic device, the user could push it back to the original position. Then, the worm shaft would be rotated from the securing direction to the releasing direction so the user could release the electronic device from the locking structure. Consequently, it is easy to secure or release the electronic device to another device through the locking structure.

First claim

What is claimed is:

1. A locking structure, provided for securing an electronic device, the locking structure comprising:
a body;
a worm shaft, pivotally assembled to the body, the worm shaft comprising a rotating shaft, a guide rail and a locking member, the guide rail annularly assembled on the rotating shaft, the locking member securely assembled at an end portion of the rotating shaft;
a guide rod, disposed on the body, one of two ends of the guide rod slidably assembled to the guide rail of the worm shaft;
a fixing base, pivotally assembled to the body; and
a linkage set, pivotally assembled to the body, one end of the linkage set abutting against the fixing base, and another end of the linkage set connected to the guide rod;
wherein when the electronic device pushes the body to rotate the body by using the fixing base as a rotating center, which causes the worm shaft to axially rotate to allow the locking member to rotate from a releasing direction to a securing direction.

2. The locking structure according to claim 1 , wherein the linkage set comprises a first linkage rod and a second linkage rod, one of two ends of the first linkage rod is connected to the guide rod, and the other end of the first linkage rod is pivotally connected to one of two ends of the second linkage rod, the second linkage rod is pivotally assembled to the body, and the other end of the second linkage rod which is not pivotally connected to the first linkage rod is abutting against the fixing base.

3. The locking structure according to claim 2 , wherein the second linkage rod is L-profiled, the second linkage rod is pivotally assembled to the body using the perpendicular portion of the second linkage rod as the pivoting center.

4. The locking structure according to claim 1 , further comprising a torsion spring disposed on the body, wherein one of two ends of the torsion spring is abutted against the body, the other end of the torsion spring is abutted against the linkage set.

5. The locking structure according to claim 1 , wherein the rotating shaft of the worm shaft comprises at least one positioning groove annularly disposed, the body comprises at least on positioning portion, the at least one positioning portion is disposed in the at least one positioning groove correspondingly.

6. The locking structure according to claim 1 , wherein the body comprises an engaging groove disposed, and the locking member of the worm shaft is protrudingly assembled in the engaging groove.

7. The locking structure according to claim 1 , wherein the fixing base comprises a fixing plate and an abutting member, the fixing plate is pivotally assembled to the body, the abutting member is securely assembled to the fixing plate, and the linkage set is abutted against the abutting member.

8. The locking structure according to claim 1 , wherein the locking member is a hook portion.

9. The locking structure according to claim 1 , wherein the locking member is an anchor shaped hook member.

10. The locking structure according to claim 1 , wherein the body comprises at least one supporting member protruded, the other end of the guide rod is slidably assembled to the supporting member.

11. The locking structure according to claim 1 , further comprising a cover provided for enclosing the body.
