Wherein, as shown in FIG. 4, the second blocking portion 54 corresponds to the second latching member 22, and the second latching member 22 is resisted by the second blocking portion 54 of the second locking member 26. And the second blocking portion 54 and the second recess portion 56 may be in a plurality of arrangements.

The connecting member 28 includes a first end 58 , a second end 60 opposite to the first end 58 , and a connecting portion 62 connected between the first end 58 and the second end 60 , wherein the first end The second end 60 is pivotally connected to the first locking member 24 and the second locking member 26 respectively, and the connecting portion 62 includes at least one slider 64 corresponding to the sliding slot 36 of the body 10 (see also the third FIG. 4, and the connecting member 28 is slid along the sliding groove 36 by the slider 64 to maintain a linear displacement. In addition, the connecting portion 62 also has a protruding pin 66.

The control member 30 is connected to the connecting portion 62 of the connecting member 28. The control member 30 includes a shaft portion 68 and a guiding slot 70. The shaft portion 68 is a pivoting hole 37 pivotally connected to the body 10. 70 is a connecting portion 62 with respect to the connecting member 28, and the protruding pin 66 on the connecting portion 62 is extended to the guiding groove 70. The guiding groove 70 has an arc shape which is an involute path centering on the shaft portion 68. Preferably, the control member 30 further includes a blocking body 72. The body 10 is provided with a limiting groove 74 relative to the blocking body 72, and the limiting groove 74 is annular with the shaft portion 68 as a center. The restriction groove 74 may be disposed on the second component 34 such that the rotation angle of the control member 30 may be limited.

In addition, as shown in FIG. 2, in the existing mechanism for causing the first latching member 20 and the second latching member 22 of the latching unit 14 to operate (the mechanism and principle are the same as in the previous application No. 098119487) Therefore, some structural details that are not related to the features of the present invention are not described herein, and include an operating unit disposed on the body 10. The unit includes an operating member 76, and a first releasing member 78 is coupled to the operating member 76. The second release member 80 and the linkage member 82 are pivotally connected to the body 10 at the center to connect the first release member 78 and the second release member 80 at both ends. As shown in FIG. 5 , the difference from the foregoing method is that the operating member 76 is pivotally connected to the body 10 , and the operating member 76 has a swing arm 84 connected to the linking member 82 . The end that is interconnected with the first release member 78. More specifically, it is preferable that the operating member 76 includes a pivot 86 pivotally connected to the body 10, the swing arm 84 includes a connecting hole 88, and the first releasing member 78 includes a protruding shaft 90 extending through The connecting hole 88, whereby the operating member 76 is operated to be pivotally operated, and the swing arm 84 can simultaneously displace the first releasing member 78 and the linking member 82.

6 and 7 show that when the control member 30 is rotationally displaced, since the protruding pin 66 of the connecting member 28 extends into the guiding groove 70 of the control member 30, when the control member 30 is displaced to an unlocked state, In the position, the connecting member 28 is driven by the control member 30 and linearly displaced, and the connecting member 28 is used to drive the first locking member 24 to be displaced, so that the first blocking portion 50 of the first locking member 24 is opposite to the first locking portion 24. The first latching member 20 is displaced from the first latching member 20 and displaces the first recessed portion 52 relative to the first latching member 20 such that the first latching member 20 can be in the first recessed portion 52 internal displacement. At the same time, the second locking member 26 is also displaced by the connecting member 28, so that the second blocking portion 54 of the second locking member 26 is displaced from the second latching member 22 and disengaged from the second latching member 22, The second recess 56 is displaced relative to the second latching member 22 such that the second latching member 22 can also be displaced within the second recessed portion 56. Thus, the first latching member 20 and the second latching member 22 release the latching of the first locking member 24 and the second locking member 26, and only have the first elastic member 42 and the second elastic member. The elastic top of the piece 48 is resisted.

FIG. 8 further shows that when the operating member 76 is operated and lever-shaped, the swing arm 84 can drive the first release member 78 and the linkage member 82 together, and the second release member 80 is also The linkage member 82 drives the displacement, and the operation is performed by the first release member 78 to be displaced to the first locking member under the unlocked condition shown in the foregoing FIGS. 7 and 8. The second latching portion 22 is also moved by the second releasing member 80 to be displaced into the second recess portion 56 of the second locking member 26. Thereby, the first latching member 20 and the second latching member 22 can release the latching of the housing 12, so that the housing 12 can be detached from the body 10.

As described above, before the unlocking of the housing locking device of the present invention, the first latching member 20 is resisted by the first blocking portion 50 of the first locking member 24 and is fastened to the housing 12 The second latching member 22 is abutted by the second blocking portion 54 of the second locking member 26 and is fastened to the other side of the housing 12 to ensure that the housing 12 is mounted on the body 10. The stability of the above. Such a design can indeed prevent the user from misoperation, and can also be used to enhance the locking property in an unexpected situation, for example, the product is dropped and easily causes the casing to fall off from the electronic product.
