[0031] In this embodiment, the articles to be transferred are placed in the cavity 201, and the box cover 110 is slid downward along the side wall of the cavity 201, so that the lower end surface of the box cover 110 can abut against the articles in the cavity 201. At this time, the corresponding positioning rod 300 is driven to move synchronously by the driving assembly, so that one end of the positioning rod 300 extends out of the corresponding end of the box cover 110. At this time, one end of the positioning rod 300 is inserted into the corresponding positioning hole 202, so that the box cover 110 is preferably fixed in the cavity 201. At the same time, it is kept abutting against the articles, so that the box cover 110 can always limit the articles in the cavity 201. Compared with the existing ones, when this kind of combined hollow board box is actually used, when the box body 100 encounters a bump, it can reduce the bump caused by the up and down shaking of the articles in the box body 100, thereby reducing the damage caused by the articles when the box body 100 is transferred, and it is more practical.

[0032] The combination of the box body 100 and the box cover 110 allows the articles in the cavity 201 to be better protected during transportation, thereby reducing the damage caused by bumps and collisions when the articles are shaken up and down in the cavity 201.

[0033] Among them, a plurality of positioning holes 202 are opened along the height direction of the cavity 201. When the cover plate is adjusted according to the height of the article in the cavity 201, the positioning rods 300 can be inserted into the corresponding positioning holes 202, so that the cover plate can be positioned at different heights in the cavity 201, thereby limiting the position of articles at different heights in the cavity 201, which is more practical.

[0034] Among them, the support plates 410 are fixedly installed on the bottom wall of the installation cavity 401, so that the positioning rod 300 is slidably installed in the installation cavity 401 through the two support plates 410. At the same time, the two support plates 410 limit the movement of the positioning rod 300, so that the positioning rod 300 can only slide horizontally between the two support plates 410, so that the positioning rod 300 can be better inserted into the corresponding positioning hole 202, and the box cover 110 has a better positioning effect;

[0035] Among them, the bottom wall of the box body 100 and the four corners are provided with insertion holes, and the upper end surface of the box body 100 and the four corners are fixedly installed with insertion rods 101. When the box body 100 needs to be stacked on another box body 100, the insertion rods 101 on the box body 100 will be inserted into the corresponding insertion holes on the other box body 100, so that the stacking of the two boxes 100 is more stable and the use effect is better;

[0036] Among them, a limiting groove 203 with an opening upward is provided on the side wall opposite to the cavity 201 along its height direction, and a limiting block 330 is fixedly installed on the side wall opposite to the box cover 110 and is inserted into the corresponding limiting groove 203. The limiting groove 203 limits the limiting block 330, so that the lifting and lowering of the box cover 110 in the cavity 201 is more stable, and the lifting and lowering effect of the box cover 110 is better;

[0037] Among them, an elastic pad is installed on the lower end surface of the box cover 110, and the elastic pad on the box cover 110 abuts against the object, so that the box cover 110 can better limit the object in the cavity 201, and the use effect is better;

[0038] When it is actually used, the opposite side walls of the box body 100 are provided with transport grooves 102 for transporting the box body 100 . The box body 100 can be better transported through the two transport grooves 102 , making the transportation of the box body 100 more convenient.

[0039] like Figure 1-5 As shown, in this embodiment, the driving assembly includes a ring 420 arranged on the positioning rod 300, and a spring 430 is provided on the positioning rod 300 between the ring 420 and the support plate 410. The spring 430 is used to always push the ring 420 to approach the positioning hole 202. A moving part is also provided in the installation cavity 401, and the moving part is used to drive one end of the two positioning rods 300 to retract into the installation cavity 401.

[0040] In this embodiment, by setting the collar 420, the spring 430 and the moving member, the collar 420 is threadedly installed on the corresponding positioning rod 300, one end of the spring 430 abuts on the collar 420, and the other end abuts on the corresponding support plate 410, so that the spring 430 is installed, and the spring 430 always pushes the collar 420 to move toward the positioning hole 202, so that one end of the positioning rod 300 is preferably extended, and one end of the positioning rod 300 is always inserted into the corresponding positioning hole 202, so as to realize the positioning of the box cover 110 in the cavity 201;

[0041] In actual use, when it is necessary to remove the box cover 110 and take out the items in the cavity 201, the two positioning rods 300 are driven closer to each other by the moving part, so that one end of the positioning rod 300 slides out from the corresponding positioning hole 202, thereby releasing the positioning of the box cover 110 in the cavity 201, and the box cover 110 can be taken out of the cavity 201, that is, the items can be taken out of the cavity 201.

[0042] like Figure 1-5 As shown, in this embodiment, a fixing plate 440 is provided on one of the two positioning rods 300, and a tooth groove 451 is provided on the outer wall of the other positioning rod 300 along its length direction;

[0043] The moving part includes a rack 441 arranged on the fixed plate 440, and a rotatable gear 460 is arranged on the bottom wall of the installation cavity 401. The rack 441 and the tooth groove 451 are both meshed with the gear 460. The movement of the rack 441 is used to drive the two positioning rods 300 to move away from or closer to each other.

[0044] In this embodiment, by setting the fixing plate 440, the tooth groove 451, the rack 441 and the gear 460, one of the two positioning rods 300 is moved by driving the rack 441, and the gear 460 is driven to rotate when the rack 441 moves, thereby driving the other positioning rod 300 to move through the tooth groove 451, so that the two positioning rods 300 move synchronously, and one end of the two positioning rods 300 slides out from the corresponding positioning holes 202, thereby releasing the positioning of the box cover 110 in the cavity 201;

[0045] The fixing plate 440 is fixedly mounted on one of the two positioning rods 300 along the axial direction of the positioning rod 300, and the rack 441 is fixedly mounted on the fixing plate 440, so that when the rack 441 moves, it can drive the positioning rod 300 on which the fixing plate 440 is mounted to move;

[0046] There are circular holes on the opposite side walls of the installation cavity 401, and round rods 461 inserted into the corresponding circular holes are fixedly installed at both ends of the gear 460. By inserting the round rods 461 into the corresponding circular holes, the gear 460 can be rotatably installed in the installation cavity 401.

[0047] During actual use, a slot is provided on the support plate 410, and a block 500 is fixedly installed on the positioning rod 300 with a tooth groove 451, which is inserted into the corresponding slot, so that the positioning rod 300 with the tooth groove 451 is limited, which can prevent the positioning rod 300 from rotating during use, causing the tooth groove 451 on the positioning rod 300 to be out of mesh with the gear 460, thereby affecting the actual use of the positioning rod 300.

[0048] like Figure 1-4 As shown, in this embodiment, a sliding groove 311 connecting to the installation cavity 401 is provided on the upper end surface of the box cover 110 along its extension direction, a groove 312 is provided on the sliding groove 311, a lever 442 extending out of the sliding groove 311 is provided on the rack 441, and a handle 320 overlapped in the groove 312 is provided on the lever 442.

[0050] The side wall of the lever 442 fits with the side wall of the sliding groove 311, so that the lever 442 can only slide stably along the sliding groove 311, thereby better driving the rack 441 to move stably;

[0051] The lever 442 is fixedly provided with a handle 320, and the lever 442 can be driven to move by the handle 320. At the same time, the box cover 110 can be conveniently taken out of the cavity 201 by the lever 442, which is more convenient to use.

[0052] In actual use, the groove 312 is opened on the upper end surface of the box cover 110, wherein the upper end surface of the handle 320 is flush with the upper end surface of the box cover 110, thereby preventing the handle 320 from protruding out of the box cover 110 and affecting the stacking between the two boxes 100, and having good practicality.

[0053] Working principle: First, put the items into the cavity 201, and then slide the handle 320 along the sliding groove 311 to retract the two positioning rods 300 into the installation cavity 401. At this time, move the box cover 110 down along the cavity 201 so that the elastic pad of the box cover 110 abuts against the items in the cavity 201 to limit the position of the items in the cavity 201. Then release the handle 320 to insert the positioning rod 300 into the corresponding positioning hole 202. The position of the box cover 110 is positioned, and then the box body 100 is transported through the transport grooves 102 on both sides of the box body 100. After the transportation is completed, pull the handle 320 to disengage one end of the positioning rod 300 from the corresponding positioning hole 202, release the positioning of the box cover 110 in the cavity 201, and then remove the box cover 110 from the cavity 201 to take out the items in the cavity 201.

[0054] In short, the above is only a preferred embodiment of the present utility model, and all equivalent changes and modifications made according to the scope of the patent application of the present utility model should fall within the scope of the present utility model patent.
