The engaging convex portion 34 is obliquely inserted into the engaging recess 171 of the third side wall 17 of the main casing 10. Pressing the cover 31 again causes the main hook 32 to slide against the first side wall 13 of the main casing 10 to slide into the main casing 10. During the sliding process, the hook portion 323 of the main hook 32 is received by the first side wall 13. Pushing, the portion of the connecting rod portion 321 of the main hook 32 close to the hook portion 323 is bent and deformed, and the hook portion 323 is tilted away from the first side wall 13 of the main casing 10, and when the hook portion 323 slides to the latch At the portion 131, the abutting force of the first side wall 13 against the hook portion 323 disappears, the connecting rod portion 321 of the main hook 32 is straightened, the hook portion 323 is engaged with the engaging portion 131, and the engaging surface 3231 of the hook portion 323 is resisted. The auxiliary hook 13 slides along the second side wall 15 toward the main housing 10 to deform, and when it slides to the auxiliary card slot 151, the deformation disappears, and the auxiliary hook 33 is engaged. The fixed end 351 of the elastic piece 35 is fixed on the cover plate 31, and the resisting end 353 is pressed by the inner wall of the limiting recess 133 on the first side wall 13, and is rotated at a certain angle with respect to the fixed end 351.

Referring to FIG. 8 again, when the electronic device housing 100 is turned on, the control button is The end surface 511 of the operating portion 51 of the 50 presses the control button 50, and the actuating portion 53 of the control button 50 pushes the side flap 73 of the pushing resist 70 so that the side flap 73 and the pivot 71 rotate together about the axis of the pivot 71. During the rotation of the rotation resisting member 70, the side flap 73 abuts against the hook portion 323 of the main hook 32, and the portion of the connecting rod portion 321 of the main hook 32 near the hook portion 323 is bent and deformed in the X direction, so that the hook portion 323 The locking surface 3231 of the hook portion 323 no longer resists the limiting surface 1311 of the latching portion 131, and the latching surface 3231 is inclined with respect to the limiting surface 1311, and the locking surface 3231 of the hook portion 323 is no longer abutted against the limiting surface 1311. It is resisted by the edge 1313 of the holding portion 131. The rotation resisting member 70 continues to rotate until the limiting boss 731 abuts against the first side wall 13. Under the abutment of the rotating abutting member 70, the hook portion 323 of the main hook 32 is adjacent to the edge 1313 of the engaging portion 131. The holding surface 3231 slides in the oblique direction and finally comes off the holding portion 131. When the main hook 32 is disengaged from the holding portion 131, the force against which the elastic piece 35 is pressed is lost, and the bending angle between the abutting end 353 and the fixed end 351 is restored to a free state, in the process of restoring deformation. The cover 31 is lifted up near one end of the first edge 311.

The cover 30 is pulled at the first edge 311. Since the surface of the auxiliary hook portion 333 of the auxiliary hook 33 that intersects the auxiliary connecting rod 331 is a slope 3331, when the auxiliary hook 33 is held in the auxiliary card slot 151 After that, the inclined surface 3331 is in contact with the inner wall of the auxiliary card slot 151, so that the auxiliary hook 33 can be detached from the auxiliary card slot 151 along the inclined surface 3331 with a small force, and the clamping force is small, and only assists. The function of positioning is to be detached from the auxiliary card slot 151 under the pulling of the external force. Then, the cover body 30 is pulled obliquely, and the engaging convex portion 34 is pulled out from the engaging recess 171 on the third side wall 17, thereby completing the opening of the electronic device outer casing 100. When the control button 50 is stopped, the control button 50 falls back under the action of gravity, and returns to the original position. The flank 73 of the rotation resisting member 70 is also rotated by the gravity of the control button 50 in the direction of approaching the control button 50.

In the electronic device housing 100 described above, only the engaging convex portion 34 is inserted into the engaging recess 171 when closed, and the pressing of the cover 30 can be completed; when the opening is performed, only the control button 50 is pressed, and the control button 50 is pushed. The rotation of the pushing member 70 further pushes the main hook 32 to disengage from the holding portion, and then pulls the cover 30 to disengage the auxiliary hook 33 and the engaging convex portion 34 from the main casing 10.

Of course, in the electronic device outer casing 100, the actuating portion 53 of the control button 50 can also directly push the main hook 32 away from the main casing 10 to open the electronic device outer casing 100. However, since the cover body 30 of the electronic device outer casing 100 is engaged by the plurality of main hooks 32, the actuating portion 53 of the control button 50 is required to be long, and the operating portion 51 acts on the actuating portion 53 only at the intermediate portion. When the two ends of the actuating portion 53 do not bend when the main hook 32 is pushed, and the same resisting force can be applied to the main hook 32, the rigidity of the material selected for the actuating portion 53 is required to be good. If the rotation resisting member 70 is added between the main hook 32 and the control button 50, since the two ends of the rotating abutting member 70 are inserted into the pivot fixing member 711, only the pivot 71 can be rotated, and the material is The rigidity requirement is low. In the present embodiment, the structure in which the rotation resisting member 70 is added is employed.

It can be understood that the holding portion 131 can also be a protrusion protruding from the first side wall 13 , and the main hook 32 is fixed to the main casing 10 by being held on the lower surface of the protrusion. The engaging protrusions 34 can also be provided in the form of auxiliary hooks 33, but in consideration of some computer cases, DVD (digital video disc) players and the like on electronic devices. An opening of the optical disc drive or the like is provided, so that the engaging convex portion 34 is disposed on the third edge 315 of the cover 30 near the cover 31 to engage the engaging convex portion 34 with the third side wall 17 of the main casing 10. The recesses 171 are matched to avoid the opening of the optical disc drive, etc., and the latching projections 34 can be provided in the form of the auxiliary hooks 33 for the electronic device outer casing which does not need to open the opening of the optical disc drive or the like.

In summary, the present invention has indeed met the requirements of the invention patent, and has filed a patent application according to law. However, the above description is only a preferred embodiment of the present invention, and it is not possible to limit the scope of the patent application of the present invention.
