Preferably, referring to fig. 5, a stopper 117 is formed at the outer side of the third plate portion near the push button, and when the splice unit is formed, the stoppers of the respective detachable locking mechanisms are surrounded together to protect the push button from accidental touching the push rod, resulting in unlocking of the splice unit.

The action principle of the splicing unit is as follows:

1) The spring pin and the button are in a locking state when being ejected bidirectionally, and are in an unlocking state after being tightened bidirectionally;

2) Before splicing, each splicing unit is positioned in an unlocking state in advance, namely, the first hook part is hung in the tightening gear hole, when two splicing units are spliced, the elastic pin in the misplug of one splicing unit is retracted under the driving of the second connecting block of the other splicing unit, and then the ejector rod part is driven to drive the first hook part to separate from the tightening gear hole, at the moment, the locking mechanism can be driven by the restoring force of the elastic piece to change from the unlocking state to the locking state, at the moment, one part of the elastic pin is ejected from the first connecting block and is inserted into the third through hole of the second connecting block of the other splicing unit, and two adjacent splicing units are locked.

3) When the two splicing units are disassembled, the button is pressed by external force, the button is retracted, and the first hook part can be driven to be separated from the ejection gear hole and pushed to the tightening gear hole. At this time, the elastic pin also retracts at the same time, the two splicing units can be disassembled, and the elastic pin returns to the locking state again under the driving of the restoring force of the elastic piece.

The invention also provides a splicing body comprising at least two splicing units, wherein the two adjacent splicing units are spliced in the horizontal direction or the vertical direction, the second connecting block of one splicing unit is inserted into the slot of the adjacent splicing unit, in the inserting process, the elastic pin in the slot of the other splicing unit is retracted under the driving of the second connecting block of the other splicing unit, the ejector rod part is driven to drive the first hook part to separate from the tightening gear hole, the locking mechanism is driven by the elastic part to be changed from the unlocking state to the locking state, and the elastic pin is ejected from the first connecting block into the slot and is inserted into the third through hole of the second connecting block of the other splicing unit, so that the two adjacent splicing units are locked. Therefore, the splice body applying the splice unit can finish locking in the direct splicing process of the splice unit, and is simple in assembly and convenient to operate.

Through splicing a plurality of splice units in the horizontal direction or the vertical direction, can splice and form multiple structures, the user can splice a certain amount of splice units according to own needs. For example, the packaging box can be formed into a closed type or an open type packaging box, can be applied to the fields of packaging logistics and the like, can be expanded in a horizontal plane, can be formed into a detachable spliced wall body or plate body, and can be applied to the fields of building decoration and the like. The toy bricks can also be used as the high-level toy bricks, at the moment, the stop block 117 is not arranged at the position, close to the button, of the outer side of the third plate part, and reverse 180-degree splicing can be performed, so that the toy bricks, simple furniture, houses of pets and the like which are wanted by children can be spliced.

FIG. 9 is a perspective view of a preferred embodiment 1 of a splice of the present invention; FIG. 10 is a perspective view of a preferred embodiment 2 of the splice of the present invention; referring to fig. 9, the splicing unit of the invention can be spliced into a packaging box which is applied to the field of packaging logistics, the packaging box can be composed of six or five splicing units, the six splicing units are spliced into a closed square box body, and the five splicing units are spliced into an open square box body with one surface being short. When the packaging box is applied to logistics, the packaging box can replace the traditional packaging box, and is very high in standardization degree, very convenient to assemble and disassemble, and capable of easily realizing relevant works such as recycling centralized processing, thereby protecting the environment and saving the whole social resources.

Referring to fig. 10, the splicing unit of the present invention can be spliced into a planar wall or a planar plate for application in the field of decoration construction, and is formed by arbitrarily splicing a plurality of splicing units, and the plurality of splicing units are spliced on a horizontal plane to form a planar plate or a planar wall. Referring to fig. 10, the planar plate body is formed by splicing four splicing units, and is very firm as a whole, very convenient to assemble and disassemble after splicing due to the very high standardization degree in the aspect of building decoration, so that the current situation that the conventional building material is inconvenient to construct and can not be reused after being used once can be changed.

The splicing unit applying the locking mechanism can splice more forms, so that the splicing is more flexible, and the splicing body can finish locking simultaneously in the direct splicing process of the splicing unit, is simple to assemble and is convenient to operate. The splicing unit can be spliced by any person at will according to the needs and the size can be adjusted at the later stage in the splicing process, so that the product cannot be damaged at all, and the splicing unit has wide application prospect.

The above embodiments are described in detail with reference to the accompanying drawings. Modifications and variations in the above-described embodiments may be made by those skilled in the art without departing from the spirit of the invention, which fall within the scope of the invention.
