Description of the main elements

The following detailed description will further illustrate the invention in conjunction with the above-described figures.

Detailed Description

Referring to fig. 1 to 4, a casing 100 includes a frame 20 and a cover 60. The frame 20 includes a bottom case 22, and a first sidewall 24, a second sidewall 23, and a third sidewall 25 circumferentially fixed on the bottom case 22. The first side wall 24, the second side wall 23 and the third side wall 25 form an opening 26 away from the edge of the bottom case 22. The second sidewall 23 is parallel to the third sidewall 25 and disposed at both ends of the first sidewall 24. The opening 26 is used to accommodate an electronic device. The cover 60 is disposed on the first sidewall 24 to cover the opening 26.

The first side wall 24 forms a perforation 28. The perforation 28 includes a first edge 30, a second edge 31 and two third edges 33 between the first edge 30 and the second edge 31. A projection 35 extends towards the bottom shell 22, away from the third edge 33 of the bottom shell 22. The second side wall 23 and the third side wall 25 also have a first sliding groove 34 and a second sliding groove 39 formed thereon. The axial directions of the first slide groove 34 and the second slide groove 39 are the same as the axial direction of the through hole 28.

A fixing member 90 is fixedly connected to the first side wall 24. The fixing member 90 includes a first fixing piece 92 disposed at an outer side of the first sidewall 24. The first fixing piece 92 forms a first through hole 94. The distance between the first through hole 94 and the third side wall 25 is smaller than the distance between the first through hole 94 and the second side wall 23. The fixture 90 also includes a fixture portion 96. The fixing portion 96 is fixed to the inner side of the first side wall 24. The first fixing piece 92 is vertically fixed to the fixing portion 96. The first side wall 24 forms a positioning hole 32. The first fixing plate 92 is disposed outside the first sidewall 24 through the positioning hole 32. In this embodiment, the fixing portion 96 is formed with two first fixing holes 91, the first side wall 24 is formed with two second fixing holes 21 aligned with the two first fixing holes 91, and two screws (not shown) are screwed into the two second fixing holes 21 and the two first fixing holes 91 to fix the fixing portion 96 to the first side wall 24.

The cover 60 includes a cover plate 62, a first side plate 64 and two second side plates 82. The cover plate 62 includes a first side 66, a second side 68, and two third sides 70 connected between the first side 66 and the second side 68. The two second side plates 82 are fixed to the two third sides 70. The two second side plates 82 face the bottom case 22 and are vertically protruded on the cover plate 62. At least two contact parts 84 are convexly arranged on two opposite sides of the two second side plates 82. The two contact pieces 84 are slidably disposed on the first sliding groove 34 and the second sliding groove 39 and contact the second side wall 23 and the third side wall 25. The two abutting pieces 84 can slide out of the first sliding groove 34 and the second sliding groove 39 to separate the cover 60 from the frame 20.

The first side plate 64 is secured to a first side 66. The outer side and the inner side of the first side plate 64 are respectively provided with a second fixing piece 72 and a limiting piece 74 in a protruding manner. The second fixing plate 72 forms a second through hole 76. The limiting piece 74 is parallel to the cover plate 62. The limiting sheet 74 includes a limiting portion 86 fixed on the first side plate 64, and a first hook portion 78 and a second hook portion 80 protruding from the upper and back sides of the limiting portion 86. The stopper portion 86 forms a stopper hole 71. The first hook portion 78 and the second hook portion 80 are disposed on the inner side of the first sidewall 24 through the through hole 28. The first hook 78 is proximate the first edge 30 and the second hook 80 is proximate the second edge 31.

When the two contact pieces 84 slide into the first sliding chute 34 and the second sliding chute 39, and the cover 60 is placed on the first sidewall 24 to cover the opening 26, the first through hole 94 is aligned with the second through hole 76.

When the cover plate 62 slides along the first sliding groove 34 and the second sliding groove 39 toward the lock 10 to abut against the lock 10 after the lock 10 is locked by passing through the first through hole 94 and the second through hole 76 to lock the cover 60 and the frame 20, the second side plate 82 close to the third side wall 25 can rotate around the first through hole 94 toward the second side plate 82 far from the third side wall 25 under an external force due to the proximity of the first through hole 94 to the third side wall 25, so that the stroke of the abutting part 84 on the second side plate 82 far from the third side wall 25 along the first sliding groove 34 is greater than the stroke of the abutting part 84 on the second side plate 82 near the third side wall 25 along the second sliding groove 39. When the second side plate 82 close to the third side wall 25 rotates around the first through hole 94 toward the second side plate 82 far from the third side wall 25, the contact part 84 on the second side plate 82 far from the third side wall 25 can slide out of the first sliding groove 34, and the contact part 84 on the second side plate 82 close to the third side wall 25 cannot slide out of the second sliding groove 39. When the contact piece 84 on the second side plate 82 away from the third side wall 25 slides out of the first sliding slot 34 and the cover 60 continues to rotate on the plane of the cover plate 62, the first hook 78 is hooked on the first edge 30. When the abutting part 84 on the second side plate 82 far from the third side wall 25 slides out of the first sliding slot 34 and the second side 68 of the cover plate 62 rotates around the first side 66, the protrusion 35 is received in the limiting hole 71 and abuts against the edge of the limiting hole 71 far from the third side wall 25 so as to prevent the cover body 60 from rotating. In this way, the cover 60 cannot be opened by rotating, and since the contact piece 84 on the second side plate 82 close to the third side wall 25 cannot slide out of the second chute 39, the cover 60 cannot be opened in the vertical and horizontal directions relative to the cover 60, so that the cover 60 cannot be opened without opening the lock 10.

The distance between the first end point 77 of the first hook portion 78 far away from the position-limiting portion 86 and the second end point 79 of the second hook portion 80 far away from the position-limiting portion 86 is slightly smaller than the aperture of the through hole 28 in the direction parallel to the bottom case 22, so that the position-limiting piece 74 can just pass through the through hole 28. The first hook portion 78 further includes a third end 81. The third end point 81 is farther from the first side plate 64 than the first end point 77 and is closer to the position-limiting portion 86, so that the first hook portion 78 forms a first wedge-shaped surface 75, which facilitates the insertion of the position-limiting piece 74 into the through hole 28.

In the case 100, when the lock 10 is not unlocked, the limiting piece 74 is blocked by the frame 20 when the cover 60 is detached, so as to prevent the cover 60 from being detached, thereby preventing others from unlocking the cover 60.

It should be understood by those skilled in the art that the above embodiments are only for illustrating the present invention and are not to be used as a limitation of the present invention, and that suitable changes and modifications to the above embodiments are within the scope of the present disclosure as long as they are within the spirit of the present invention.
