Furthermore, the bottom of the slot of the upper half section is a cross or a groove.
Further, both ends of the connecting rod are all provided with a circle of skirt edges around the periphery of the slot, the outer diameter of the skirt edges is larger than that of the through hole, and after the sealing rod is inserted into the through hole, the upper half section and the lower half section are abutted and screwed up, so that the skirt edges are pressed on the side walls of the through hole to finish sealing.
Further, both ends of the sealing rod after screwing and fixing are flush with the upper surface and the lower surface of the building block.
Furthermore, two ends of the connecting rod are conical heads, and the diameter of each conical head is larger than that of each slot, so that interference fit grafting of the conical heads and the slots is realized.
Compared with the prior art, the utility model has the advantages that:
1. through holes are formed in the surface of the building block, the inside of the building block can be filled, and therefore building blocks with various weights and materials are produced, and the building block is suitable for diversified demands in the market.
2. The building block of the utility model has the advantages that the two mutually connected building block connecting points are made on the sealing rod, the connecting points can be hidden after the building block is lapped, the structure is simple, and the appearance of the building block is ensured by the lapping.
3. The whole building block of the utility model has waterproof design and diversified use scenes.
4. The building blocks are connected by inserting the connecting rods into the slots in an interference fit manner, so that the building blocks are simple and easy to operate, and the assembly degree of freedom is higher.

Detailed Description
In order to make the objects, technical solutions and advantages of the present utility model more apparent, the technical solutions of the present utility model will be further described below.
As shown in figure 1, the utility model provides a large building block which is convenient to lap joint and fix, and a plurality of groups of symmetrical through holes 1 are arranged on the upper surface and the lower surface of the building block; through-hole 1 is used for packing to the building blocks inside, and in this embodiment, the surface of building blocks is wrapped up through the rubber waterproof layer, and the inside ABS that fills of building blocks also can pack sand and some fine materials that do not volatilize harmful substance, and the child of being convenient for plays.
After filling, each group of symmetrical through holes 1 is inserted with a sealing rod 2 for sealing; as shown in fig. 2, the sealing bar 2 comprises an upper half 21 and a lower half 22 which are detachably connected; the end of the upper half section 21 facing the lower half section 22 is a bolt, and the end of the lower half section 22 facing the upper half section 21 is a threaded hole; the upper half section 21 is inserted from the upper surface through hole 1 of the building block, and the lower half section 22 is inserted from the lower surface through hole 1 of the building block, and is screwed and fixed through bolts after being inserted. The slot bottom of the upper half section 21 is cross or linear groove, so that the screw driver can be conveniently screwed and fixed, and the screw driver can be conveniently screwed. Two ends of the connecting rod 3 are provided with a circle of skirt edges around the periphery of the slot, the outer diameter of the skirt edges is larger than the outer diameter of the through hole 1, and when the sealing rod 2 is inserted into the through hole 1, the upper half section 21 and the lower half section 22 are in butt joint and screwed up, so that the skirt edges are pressed on the side wall of the through hole 1 to form a sealing structure; the two ends of the seal rod 2 after screwing and fixing are flush with the upper surface and the lower surface of the building block, so that the surface of the building block can be smooth, and the building block assembly effect is better.
