[0016] Figure 3 is Figure 1 the left view of

[0017] Figure 4 is a structural schematic diagram after splicing of two Lego brick bases. Detailed Embodiments

[0018] The following Figures 1 to 4 is combined with

[0019] and Figure 1 and Figure 2 to further illustrate the technical solution of the present utility model through specific embodiments. Figure 4 As shown in the convenient-to-assemble anti-loosening Lego brick structure, it includes: a Lego brick base 1 with a cuboid structure. On the front of the Lego brick base 1, there are outwardly protruding positioning blocks 2 arranged at intervals. On the back of the Lego brick base 1, there are inwardly concave positioning grooves 4 corresponding to the positioning blocks 2 one by one. As

[0020] shown, two adjacent Lego brick bases 1 can be spliced through the cooperation of the positioning groove 4 and the positioning block 2, with accurate positioning and high assembly efficiency.

[0021] In this embodiment, the cross-section of the positioning block 2 is an isosceles trapezoid structure, and the structure of the positioning groove 4 is the same as that of the positioning block 2, which is beneficial for the positioning block of the rear Lego brick base to quickly enter the positioning groove of the front Lego brick base for guiding during assembly, further improving the assembly speed. The Lego brick base 1 and the positioning block 2 adopt an integrated structure and are integrally cast from raw materials through a mold, with high production efficiency.

[0022] On the top surface of the Lego brick base 1, there is a first steel bar positioning hole 6 extending to the bottom surface, which is beneficial for the steel bar to penetrate through two upper and lower Lego brick bases 1. The two upper and lower Lego brick bases 1 are locked through the steel bar. After the construction is completed, the first steel bar positioning hole 6 can also be grouted, and after curing, it can prevent the Lego brick base 1 from loosening.In addition, a second steel bar positioning hole 3 extending to the back surface is provided on the front surface of the Lego brick base body 1. The second steel bar positioning hole 3 can be horizontally penetrated by steel bars, improving the structural stability of the two Lego brick base bodies 1 on the left and right. In this embodiment, the number of the first steel bar positioning holes 6 is at least 2, and the number of the second steel bar positioning holes 3 is at least 2. The second steel bar positioning holes 3 are respectively penetrated by at least 2 steel bars to avoid deflection.

[0023] During the assembly process, in order to avoid looseness after the assembly of two adjacent Lego brick base bodies 1, a jack 5 communicating with at least one positioning groove is concavely provided in the top surface of the Lego brick base body 1, and a through hole 7 corresponding to the jack 5 is vertically provided on the positioning block 2. As Figure 2 shown, through holes 7 are respectively provided on the positioning blocks 2 at the left and right edges. It is not necessary to process through holes 7 for all the positioning blocks 2, reducing the cost.

[0024] As Figure 3 and Figure 4 shown, the jack 5 is a stepped hole. During the assembly process, first, two adjacent Lego brick base bodies 1 are spliced through the cooperation of the positioning groove 4 and the positioning block 2, and a pin 8 extending into the through hole is installed in the jack 5 for locking, avoiding looseness of two adjacent Lego brick base bodies 1 and ensuring structural stability.

[0025] In this embodiment, the pin 8 is a stepped pin shaft, which has high axial stability in the jack 5. A chamfer is provided at the bottom of the pin 8 to facilitate insertion into the through hole 7. The adjacent two Lego brick base bodies are locked by the pin 8, which is convenient for construction.
