Hereinafter, embodiments will be described with reference to the drawings. The embodiments described below do not limit the contents of the invention described in the claims. The entire contents of the configurations shown in the following embodiments are not limited to those required as solutions of the inventions described in the claims.

Referring to fig. 1 to 21, the present embodiment provides a splicing structure, which includes a plurality of first splicing units 11. The first building elements 11 may be embodied as plate-like or block-like structures. Each of the first building units 11 includes a main body portion 12 and a connecting portion 13.

The outline shape of the main body 12 is 6 n-sided polygon, where n is a positive integer, for example, n may be 1, when n is 1, the outline shape of the main body 12 is hexagonal, when n is 2, the outline shape of the main body 12 is dodecagon, when n is 3, the outline shape of the main body 12 is octadecagon, and the like.

Each edge 16 of the main body 12 is provided with a connecting portion 13, and the connecting portion 13 and the main body 12 are of an integral structure, for example, the connecting portion 13 and the main body 12 can be connected by injection molding, sheet metal or welding.

The connecting parts 13 on each side 16 of the main body part 12 of each first assembling unit 11 are connected with each adjacent first assembling unit 11 through sliding pairs, each sliding pair between any two first assembling units 11 comprises a first sliding groove 14 arranged on the connecting part 13 of one first assembling unit 11 and a sliding fit structure 15 which is arranged on the connecting part 13 of the other first assembling unit 11, can be connected with the first sliding groove 14 and slides along the first sliding groove 14, and the sliding direction of each sliding pair is the same as the extending direction of the side 16 where the sliding pair is located.

In this embodiment, the first sliding groove 14 has two groove side walls 21, which are disposed opposite to each other and keep a certain distance, i.e., a groove width. The bottoms of the two channel side walls 21 are connected by a channel bottom wall 22 of the first runner 14, so that a channel-shaped structure with two channel side walls and one channel bottom wall is formed.

It should be noted that any two of the first assembling units 11 are connected by a sliding pair when they are assembled together, specifically, the sliding fit structure 15 is slid into the first sliding groove 14. The first runner 14 extends in the same direction as the edge 16 of the connecting portion 13, and in order to enable the sliding engagement structure 15 to extend into the first runner 14 and slide along the first runner 14, the top of the first runner 14, i.e. the side opposite to the bottom wall 22 of the groove, is open. The extension of the first runner 14 may be the same as the extension of the edge 16 on which it is located, or less than the extension of the edge 16 on which it is located.

With the arrangement, any one of 6n sides of the 6 n-sided polygon is connected with other peripheral splicing units in a sliding pair manner, and during connection, the sliding fit structure 15 slides into the first sliding groove 14, and the sliding direction is the same as the direction of the side 16 where the sliding pair is located, so that after the sliding pair is completely connected in a sliding manner, the extension lines of the sliding direction intersect at the same point, the sliding freedom degrees of the sliding pairs can form mutual constraint.

For example, after the adjacent three sliding pairs are connected, the sliding directions of the three sliding pairs intersect at the same point, and the sliding of one sliding pair is constrained by the other two sliding pairs, so that the three sliding pairs cannot slide under the constraint action.

Therefore, after the assembly of each sliding pair is completed, the sliding pair is restrained by the other two sliding pairs, and the sliding pair cannot be unlocked under natural conditions. And when one sliding pair is failed to be connected, the other two sliding pairs still can be restrained with each other. The damage of the local first splicing unit can not influence the restraint between the whole sliding pairs, and further can not influence the strength of the whole structure.

The main body part of the first assembling unit can be of a one-time bending structure or a multi-time bending structure.

It should be noted that, in the assembly structure provided in this embodiment, after the assembly is completed, if an individual assembly unit is to be detached, a special tool needs to be used to apply a compound force in a specific direction to drive the associated first assembly units 11 to generate linkage, so that the detachment of each first assembly unit 11 can be realized.

After the assembly of the sliding pairs on the adjacent sides 16 is completed, the directions of the notches of the first sliding groove 14 and the second sliding groove 23 on the two adjacent sides 16 on the same assembly unit are opposite, specifically: the first sliding groove 14 on the assembly unit is matched with the second sliding groove 23 on the other assembly unit to form a sliding pair, the second sliding groove 23 on the assembly unit is matched with the first sliding groove 14 on the other assembly unit to form another sliding pair, the vertical freedom degrees of the two sliding pairs are opposite, and therefore mutual restraint can be achieved, and stable assembly is achieved in the vertical direction. Thus, after the assembly is completed, the two sliding pairs can form mutual restraint, and the problem that the first sliding groove 14 and the second sliding groove 23 which form the same sliding pair are separated from each other is further avoided.

The extending direction of the first sliding groove 14 and the second sliding groove 23 is the same as the extending direction of the side 16 where the first sliding groove and the second sliding groove are located, and the extending length is preferably less than or equal to the extending length of the side 16 where the first sliding groove and the second sliding groove are located.
