The lower end of the right panel 24 is detachably connected with the bottom panel 12 through a bolt structure; so as to be integrally connected with the base 1 when the cover 2 is closed. So that the box body 1 for loading the carbon blocks 6 can bear load and is convenient to hoist.

At least two hooking parts 25 for connecting the lifting rope are arranged on the box cover 2; the hooking portion 25 includes a through hole 251 formed in the case cover 2, and a hanging rod 252 fixed in the through hole 251 for hooking the hanging rope.

The present embodiment employs two pairs of hooking portions 25; wherein, a pair of the hooking portions 25 are provided on the upper panel 23. The other pair of the hooking portions 25 are provided on the front and rear panels 21, 22, respectively (not shown in the drawings). The lifting rope is conveniently connected from different directions.

It can be seen that the hooking portion 25 is hidden on the side wall of the case, so that the outer surface of the case is flat, and stacking and storage are facilitated.

The exemplary latch structure further includes a latch 3; a first bolt hole 241 and a second bolt hole 121 are respectively arranged on the lower end of the right panel 24 and the bottom panel 12; the pins 3 may be inserted into the first pin holes 241 and the second pin holes 121 at the same time for forming the pin structure. Of course, the first and second bolt holes 241 and 121 should correspond coaxially when the cover 2 is closed. At least one of the bolts 3 can penetrate through the whole box body, or two bolts can be inserted into the box body from two sides of the box body respectively. In this embodiment, two pins 3 are inserted from two sides of the case.

In order to facilitate the entry of the carbon blocks 6 into the box from the horizontal direction and reduce wear, the bottom panel 12 includes a pair of cross members 122 each having one end fixedly connected to the left panel 11; a plurality of rollers 123 which are uniformly spaced are arranged between the pair of cross beams 122; both ends of each roller shaft 123 are rotatably inserted into the cross beam 122; and the roller way is formed by the rolling of the plurality of roller shafts 123, so that the abrasion of the carbon block 6 during translation is reduced, and the carbon block is protected.

At this time, two second bolt holes 121 are formed on the side surface of the beam 122 and near the end of the beam 122; a protruding part 242 is arranged in the middle of the lower end of the right panel 24; the first bolt holes 241 penetrate through the front and rear sides of the protrusion 242; two bolts 3 are provided, and each second bolt hole 121 corresponds to one bolt; the ends of the two pins 3 are inserted into the first pin holes 241 from the front and rear sides of the protrusion 242, respectively.

In order to make the bolt 3 have a self-locking function and prevent the bolt from falling off, so that the use is convenient. Also comprises a spring 4 and a nut 5; two nuts 5 are arranged, and each nut 5 is screwed on external threads preset on the outer surface of the bolt 3; two springs 4 are arranged, each spring 4 is sleeved on the bolt 3, and two ends of the spring are respectively propped against the nut 5 and the inner wall of the cross beam 122; one end of the bolt 3 is fixedly connected with a pull rod 31; the length of the pull rod 31 is greater than the diameter of the second bolt hole 121.

It can be seen that the spring 4 drives the nut 5 to push the bolt 3 by elastic force, and normally moves towards the direction of the protruding portion 242, so as to have a self-locking function. When the lock is unlocked, the pull rod 31 is pulled to drive the bolt 3 to overcome the elastic force of the spring 4, so that the tail end of the bolt 3 is separated from the first bolt hole 241 to unlock. On the other hand, the pull rod 31 is not only a handle for operating the latch 3, but also has a length longer than the diameter of the second latch hole 121, and also plays a limiting role.

In order to reduce the protrusions, the surface of the box body is kept flat, and the box body is convenient to stack and store. The pull rod 31 is also hidden in the side wall of the box body, but at the same time, in order to facilitate the taking of the pull rod 31, a recess 124 is formed on the beam 122 at a position corresponding to the second insertion hole 121; the tie rod 31 is positioned in the pocket 124 without protruding beyond the outer surface of the cross beam 122.

Although the carbon block 6 can be lifted when the box cover 2 is opened, the carbon block 6 is pushed out of the box body conveniently when the carbon block 6 is translated, and the left panel 11 is provided with the observation hole 111. On the one hand, the position of the carbon block 6 in the box body is convenient to observe, and on the other hand, a push rod can be inserted into the observation hole 111 to push out the carbon block 6.

When in use, one of the modes of use is that the initial state is the state that the case cover 2 shown in fig. 1 is opened. The box body is arranged at the tail end of the roller conveyor, so that the carbon blocks 6 can be conveniently and directly received from the roller conveyor. The carbon block 6 is rolled by the roller shaft 123 and enters the case. Then the pull rod 31 is pulled to drive the end head of the bolt 3 to retract so as to close the case cover 2; after the first bolt hole 241 and the second bolt hole 121 are aligned, the pull rod 31 is released, and the bolt 3 is pushed to move towards the protruding portion 242 under the action of the spring 4 and is inserted into the first bolt hole 241, so that locking is completed. At this time, the carbon block 6 is completely wrapped in the box body, so that collision scratch is avoided. Finally, the carbon block 6 is tied on the hooking part 25 through the hanging rope, or the hanging hook is directly hooked on the hanging rod 252 to be lifted, so that the carbon block and the box body are transferred together. After the box body reaches the warehouse, the unlocking is not needed, and as the surface of the box body is flat and has no protrusion, the box body can be naturally piled up and stored, the space is saved, and the use is convenient.
