And a fastening spring 43 disposed between the outer casing 2 and the second fastening component 42 and providing a thrust of the second fastening component 42 away from the outer casing 2.

The second fastening component 42 has a first side 421 facing the first fastening component 41 and a second side 422 opposite to the first fastening component 41, and preferably is the rear end of FIG. The side is pivotally disposed on the outer casing 2 and can be rotated up and down centering on the pivoting portion.

Referring to FIG. 3 , FIG. 4 and FIG. 5 , the locking unit 5 includes a locking module 51 , a driving module 52 and a mounting frame 53 disposed on the outer casing 2 .

The locking module 51 has a locking member 511 that is movable against or against the second side 422 of the second fastening member 42 and is disposed between the housing 2 and the locking member 511. The interlocking spring 512.

The locking member 511 has a T-shaped shape as viewed from above in FIG. 4, and has a driving portion 513 which is in the shape of a plate and is pushed by the driving module 52, and has a rod shape and the driving portion 513 faces the second buckle. a limiting portion 514 extending in the direction of the engaging member 42 , the limiting portion 514 can extend into a gap between the second side 422 of the second fastening member 42 and the outer casing 2 for abutting against the locked state The second side 422 of the second fastening member 42.

As shown in FIG. 3, the driving portion 513 is at least partially exposed outside the casing 2, so that the user can manually pull the driving portion 513.

The locking spring 512 constantly provides the thrust of the locking member 511 toward the second fastening member 42 so that the locking member 511 can move against the second side 422 of the second fastening member 42. .

Referring to FIG. 1 , FIG. 4 and FIG. 5 , the driving module 52 is configured to be driven by the control unit 9 to drive the locking member 511 to move, and includes a driving member 521 and a impact 522. The driving member 521 is driven to move against the driving portion 513 to move the limiting portion 514 in a direction opposite to the second fastening member 42 , so that the limiting portion 514 is separated from the second fastening member 42 and the outer casing 2 . The gap.

Wherein, the driving member 521 can be implemented using a solenoid valve.

The mounting bracket 53 is disposed on the outer casing 2 and defines a sliding slot 531. The sliding slot 531 is movably disposed to limit the moving path of the limiting portion 514.

The abutting unit 6 includes two abutting modules 61 disposed on the outer casing 2. The abutting unit 6 can include a single or any plurality of abutting modules 61 according to actual needs, and is not limited thereto.

Referring to FIG. 4 , FIG. 5 and FIG. 6 , each of the abutting modules 61 has a first side 421 which can be pushed against the first fastening component 41 to abut or not to the top of the second fastening component 42 . The abutting block 611 and an abutting spring 612 disposed between the outer casing 2 and the abutting block 611 and constantly providing an outward thrust of the abutting block 611. The elastic force of the abutting spring 612 is greater than the elastic force of the fastening spring 43.

Referring to FIG. 1 , FIG. 5 and FIG. 6 , in actual use, when the drawer 82 is closed, the drawer 82 touches the closing detection unit 3 to output the detection signal related to the closing of the drawer 82 to the control unit. 9. In order to inform the control unit 9 that the drawer 82 is currently closed, at this time, the drawer locking device 1 is in a locked state, and the first fastening member 41 is pushed inwardly against the abutting block 611. The second fastening component 42 is fastened to the first side 421 of the second fastening component 42 . The limiting portion 514 of the locking component 511 extends into the second fastening component 42 . The gap between the second side 422 and the outer casing 2 abuts against the second side 422 of the second fastening component 42 so that the second fastening component 42 cannot be disengaged due to the abutment of the locking component 511. The first fastening member 41 can achieve the double locking effect. Even if the drawer locking device 1 is subjected to vibration, the fastening unit 4 does not come loose and the drawer 82 is opened.

Referring to FIG. 1 , FIG. 7 and FIG. 8 , when the drawer 82 is to be opened, the user can operate the control unit 9 to operate the corresponding driving module 52, and the drawer locking device 1 is switched to FIG. 7 . In the unlocking state shown in FIG. 8, when the driving member 521 drives the impact 522 to strike the driving portion 513 of the locking member 511, the limiting portion 514 is moved to the right in FIG. 7 to leave the second fastening. The gap between the member 42 and the outer casing 2, at this time, since the elastic force of the abutting spring 612 is greater than the elastic force of the fastening spring 43, the abutting block 611 is biased by the thrust of the abutting spring 612. The fastening member 41 is pushed out, and the second fastening member 42 is rotated upward to press the fastening spring 43 to open the drawer 82. After the drawer 82 is opened, as shown in FIG. 8, the abutting block 611 is opened. It abuts against the first side 421 of the second fastening component 42. Wherein, the elastic force of the abutting spring 612 is designed to be larger than the elastic force of the fastening spring 43, so that even if the fastening spring 43 is to press the second fastening member 42 downward, it is subject to The abutting spring 612 cannot move downward, so that the abutting block 611 can be properly abutted against the first side 421 of the second fastening component 42.

If the control unit 9 or the driving module 52 is abnormal and the drawer 82 cannot be normally opened, the user can manually move the driving portion 513 to the right in FIG. 7, and the limiting portion 514 can also be linked. Moving continues as described above to open the drawer 82.

Referring to FIG. 5, FIG. 6 and FIG. 8, when the drawer 82 is to be closed again, the user only pushes the drawer 82 in, and the first fastening member 41 will push the abutting block 611 inward again. The second fastening member 42 is not moved against the second fastening member 42. At this time, the second fastening member 42 is moved downward by the thrust of the fastening spring 43 and is fastened as shown in FIG. The first fastening component 41 is biased by the locking spring 512 such that the limiting portion 514 extends between the second side 422 of the second fastening component 42 and the outer casing 2 to The second side 422 of the second fastening member 42 is abutted, and thus switches to the locked state as shown in FIGS. 5 and 6.

Referring to FIG. 2, FIG. 3 and FIG. 4, the advantages of this embodiment can be summarized as follows through the above description:

1. By providing the fastening unit 4, the corresponding drawer 82 can be buckled at ordinary times to maintain the safety of the medicine, and the unrelated person can be arbitrarily taken away, and the locking unit 5 and the abutting unit 6 are provided by matching. Double locking can increase the locking strength. Even if it is applied to a medical vehicle that is constantly moving, the drawer locking device 1 will not be loosened due to vibration, so the drawer 82 will not be self-propelled. Open, therefore, can enhance the effect of maintaining drug safety.

The fastening unit 4, the locking module 51 and the abutting module 61 can be provided by a simple structure by providing the fastening spring 43, the locking spring 512 and the abutting spring 612. The driving force is not only easy to maintain, but also reduce installation costs.

3. When the driving unit 513 is at least partially exposed outside the casing 2, the user can manually open the drawer 82 when the control unit 9 and the driving module 52 are abnormal and cannot be operated. Do not delay the application time due to abnormal equipment.

4. By setting the off detection unit 3 to output the detection signal to the control unit 9, the control unit 9 can grasp the current open and closed state of each drawer 82, thereby improving the safety of the management medicine.

In summary, the novel drawer locking device can indeed achieve the purpose of the present invention.

However, the above is only the embodiment of the present invention, and when it is not possible to limit the scope of the present invention, all the simple equivalent changes and modifications according to the scope of the patent application and the contents of the patent specification are still This new patent covers the scope.
