Detailed Description

The invention will be further described with reference to the following examples.

The utility model discloses a specific implementation mode of high strength withstand voltage case and bag, as shown in fig. 1-2, including last box (not shown) and lower box 1 of mutually supporting, only following box is the example in this embodiment, lower box 1 includes back 11, bottom surface 12, top surface 13 and two lateral wall faces 14 that link together top surface 13, bottom surface 12 and back 11, the edge connection of every box 1 has the reinforcing tank wall 2 (as in fig. 4 and 5), the edge of back 11, bottom surface 12, top surface 13 and two sides is reinforcing tank wall 2, this reinforcing tank wall 2 includes outer wall 21, inner wall 22 and is located the first stiffening rib 23 between outer wall 21 and the inner wall 22, and the link of outer wall 21 and the link of inner wall 22 all are connected with the surface at the edge of lower box 1. Connect the first stiffening rib 23 that is equipped with in the reinforcing tank wall 2 at box 1 edge down, can strengthen the intensity that can strengthen two lower box 1's edges on the one hand, prevent that the edge of joint from being destroyed by physics for box 1's resistance to pressure is better down, and on the other hand can carry out the atress transmission to two lower boxes 1, improves the fastness of connecting.

As shown in fig. 4-7, the connection end of the outer wall 21 is connected to the edge of the lower case 1, the free end of the outer wall 21 extends outward and toward the direction away from the lower case 1 (in this embodiment, toward the upper case), and the outer wall 21 is configured such that the first reinforcing rib 23 has more installation space between the outer wall 21 and the inner wall 22, so that the volume of the first reinforcing rib 23 can be set larger, and the strength of the whole lower case 1 is better. And the outer wall 21 can increase the accommodating space inside the lower box body 1 after being bent, but the strength of the bent outer wall 21 can be relatively reduced, but the strength of the outer wall 21 is increased by the first reinforcing rib 23, so that the strength of the bent outer wall 21 can not be reduced while the inner space of the lower box body 1 is increased. The first reinforcing ribs 23 are in the shape of a honeycomb or a folded plate, in this case a folded plate.

As shown in fig. 1, the upper end of the back surface 11 of the lower case 1 is provided with a connecting portion 15, the connecting portion 15 is recessed toward the inside of the lower case 1, the bottom wall of the connecting portion 15 is provided with a notch 16, the notch 16 communicates with the inside and the outside of the lower case 1, one pull rod positioning member 17 is fixed on the connecting portion 15, the number of the pull rod positioning members 17 is two, two pull rod positioning members 17 are connected and fixed on the connecting portion 15 through a connecting plate 18, the pull rod positioning member 17 is inserted into the notch 16 and part of the pull rod positioning members 17 enter the lower case 1, each pull rod positioning member 17 is provided with a slot 171, the slot 171 is convenient for inserting a pull rod and positioning the pull rod to prevent the pull rod from shaking, one side of the pull rod positioning member 17 is bent upward to be provided with a connecting block 172 (as shown in fig. 3), a groove 173 is provided between the connecting block 172 and the side wall, when the pull rod is pulled upwards in the slot 171, the pull rod positioning piece 17 is clamped with the side wall of the connecting part 15 through the groove 173, so that the pull rod positioning piece 17 can be prevented from moving left and right, and the pull rod can move up and down more smoothly; the other side of the pull rod positioning piece 17 is connected with a second reinforcing rib 174, the second reinforcing rib 174 is a convex block, the top of the second reinforcing rib 174 is abutted against the bottom of the connecting plate 18, and the pull rod positioning piece 17 cannot be shaken in the moving process of the pull rod, so that the pull rod can move more smoothly.

As shown in fig. 2, the third reinforcing rib 3 is disposed on the inner wall of the bottom 12 of the lower case 1 at a position corresponding to the roller, and since the bottom 12 of the lower case 1 and the roller need to bear the weight of the entire lower case 1, in this application, the third reinforcing rib 3 is disposed on the bottom 12 of the lower case 1 and at a position corresponding to the roller, so as to enhance the strength of the bottom 12 of the lower case 1 and prevent the lower case 1 from being damaged by the overweight bottom 12 of the lower case 1. The side of the third reinforcing rib 3 is provided with a plurality of strip plates which are distributed in parallel, and the gravity borne by the lower box body 1 can be dispersed on each strip plate through the structure, so that the stress is more uniform.

It should be finally noted that the above embodiments are only intended to illustrate the technical solutions of the present invention, and not to limit the scope of the present invention, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present invention can be modified or replaced with equivalents without departing from the spirit and scope of the technical solutions of the present invention.
