In this embodiment, the process groove 204 may be configured on the first contact surface 101, the second contact surface 102, the first bearing surface 103, the second bearing surface 104, the first outer side 105 and/or the second outer side 106, so as to meet the requirement of the forming process of the corner body 100, which is not described herein.

As shown in fig. 1 to 6, in this embodiment, the first through holes 208 may be respectively configured in the first bearing surface 103 and the second bearing surface 104, and the second through holes 209 are respectively communicated with the process grooves 204 configured in the corner body 100, as shown in fig. 4, by configuring the first through holes 208 in the first bearing surface 103 and the second bearing surface 104, so that each fastener 500 is arranged along the height direction of the corner body 100, which is beneficial to more firm connection; by communicating the second through holes 209 with the process grooves 204 formed in the corner body 100, respectively, the problems of easy installation of the fastener 500 and easy removal of the fastener 500 can be solved.

In order to make the assembly of the corner piece 600 assembled by using at least two corner pieces 600 more regular, in a further scheme, the first outer side 105 may be parallel to the first contact surface 101, the second outer side 106 may be parallel to the second contact surface 102, so that the whole corner piece 100 may form a cuboid structure, in implementation, the length (the distance between the first outer side 105 and the first contact surface 101), the width (the distance between the second outer side 106 and the second contact surface 102) and the height (the distance between the first bearing surface 103 and the second bearing surface 104) of the corner piece 100 may be determined according to actual requirements, while in a preferred embodiment, the distance between the first outer side 105 and the first contact surface 101 may be an integral multiple, such as one time, two times, three times, etc., of the distance between the second outer side 106 and the second contact surface 102 may be an integral multiple, such as one time, two times, etc., of the distance between the second outer side 106 and the first contact surface 101, the corner piece 600 may not be increased by the same size, and the corner piece 600 may not be assembled by at least two times, and the corner piece 600 may not be completely added by the method of filling the corner piece 600.

In practical applications, the size of the corner body 100 may be determined according to practical needs, for example, in the corner body 100, the distance between the first bearing surface 103 and the second bearing surface 104 generally needs to be adapted to the height of the main board 300 or the edge strip 400, and since in the prior art, the heights of the main board 300 and the edge strip 400 are both 150mm, in a preferred embodiment, the distance between the first bearing surface 103 and the second bearing surface 104 may be 150mm.

In the corner body 100, the distance between the first outer side 105 and the first contact surface 101 should be matched with the width of the edge strip 400, where the distance between the first outer side 105 and the first contact surface 101 is equal to the width of the edge strip 400, or the distance between the first outer side 105 and the first contact surface 101 is an integer multiple of the width of the edge strip 400, or the width of the edge strip 400 is an integer multiple of the distance between the first outer side 105 and the first contact surface 101, for example, in a preferred embodiment, the distance between the first outer side 105 and the first contact surface 101 may be 50mm, 100mm or 200mm, and correspondingly, the width of the edge strip 400 may also be 50mm, 100mm or 200mm; the matching mode between the corner body 100 and the edge strip 400 is more flexible, so that the requirements of different-size combined trays can be met with low cost.

Likewise, in the corner body 100, the distance between the second outer side 106 and the second contact surface 102 should also match the width of the edge strip 400, where the distance between the second outer side 106 and the second contact surface 102 is equal to the width of the edge strip 400, or the distance between the second outer side 106 and the second contact surface 102 is an integer multiple of the width of the edge strip 400, or the width of the edge strip 400 is an integer multiple of the distance between the second outer side 106 and the second contact surface 102, for example, in a preferred embodiment, the distance between the second outer side 106 and the second contact surface 102 may be 50mm, 100mm, or 200mm, and correspondingly, the width of the edge strip 400 may also be 50mm, 100mm, or 200mm; the matching mode between the corner body 100 and the edge strip 400 is more flexible, so that the cost is low.

In practice, the rim strips 400 and the corner pieces 600 of the corresponding sizes are produced by using the minimum number of molds, and by assembling the rim strips 400 and the corner pieces 600 of different numbers and different widths on the main plate 300, the combination trays of different sizes (at least 500 combination trays of different sizes can be obtained) can be realized, and as shown in fig. 6 and 10, the versatility can be improved and the cost can be remarkably reduced.

Of course, in the embodiment, the corner body 100, the first connector 201 and the second connector 202 may be separate components, and in this case, the first connector 201 and the second connector 202 may be connected to the corner body 100 by fasteners, so that the first connector 201, the second connector 202 and the corner body 100 may be integrally connected.

It will be appreciated that, in order to make the lock hole 203 meet the requirement of matching with the first plug cavity 206 or the second plug cavity 207, a certain interval (distance) should be provided between the lock hole 203 and the corresponding first contact surface 101 or the second contact surface 102, so as to facilitate the integral molding, in a further scheme, at least a portion between the lock hole 203 and the first contact surface 101 in the first plug 201 is configured with a plurality of process grooves 204 or process holes, as shown in fig. 1-6, so that not only the portion between the lock hole 203 and the first contact surface 101 can be smoothly injection molded, but also materials can be saved, and correspondingly, in the second plug 202, at least a portion between the lock hole 203 and the second contact surface 102 is configured with a plurality of process grooves 204 or process holes, as shown in fig. 1-6, the same technical effect can be achieved.
