[0027] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0028] like Figures 1 to 3 As shown, a high connection strength two-color injection molding decorative plate includes a first decorative plate 1 and a second decorative plate 2 arranged at intervals, a first enclosure 5 is fixedly provided on the first decorative plate 1, and a second enclosure 6 is fixedly provided on the second decorative plate 2, and the first enclosure 5 and the second enclosure 6 are consistent. The high connection strength two-color injection molding decorative plate also includes:

[0029] A plurality of mother lock assemblies 3 are arranged on the first enclosure 5 and a plurality of child lock assemblies 4 are arranged on the second enclosure 6. The mother lock assemblies 3 and the child lock assemblies 4 match each other and are used to fix the adjacent first decorative panels 1 and second decorative panels 2.

[0030] The female lock assembly 3 comprises:

[0031] A guide sleeve 32 fixed on the first decorative plate 1 .

[0032] A metal plug rod 35 is slidably connected to the guide groove 34 provided on the guide sleeve 32.

[0033] A spring sheet 31 is hinged to the metal insert rod 35 , and one end of the spring sheet 31 is hinged to the inner wall of the first enclosure 5 .

[0034] The sub-lock assembly 4 comprises:

[0035] A transverse inserting block 41 is arranged outside the second enclosure 6 , and a through slot 42 is arranged on the transverse inserting block 41 .

[0036] The first enclosure 5 is provided with a limiting groove 43 for the transverse inserting block 41 to enter. When the transverse inserting block 41 enters the limiting groove 43 , the metal inserting rod 35 passes through the through groove 42 .

[0037] The initial state of the metal plug rod 35 is that the horizontal bar is on one side of the limit groove 43. During installation, it is necessary to first use the magnetic force of a strong magnet on the surface of the first decorative panel 1 that is opposite to the first enclosure 5 to attract the metal plug rod 35 and translate it along the length direction of the metal plug rod 35. Under the influence of the magnetic force, the metal plug rod 35 is driven to move in the same direction and compress the spring sheet 31 to accumulate elastic force until the metal plug rod 35 is completely on one side of the limit groove 43 and does not block the limit groove 43. At this time, one side of the second decorative panel 2 can be aligned with the first decorative panel 1, and the horizontal plug block 41 on the second enclosure 6 can be inserted into the limit groove 43 until the opposite surfaces of the first enclosure 5 and the second enclosure 6 are tightly attached. Finally, the strong magnet is removed and the metal plug rod 35 is in a state without magnetic force. Under the influence, the elastic force accumulated by the spring sheet 31 pushes it to reset and passes through the through hole 42 on the cross plug block 41, so that the cross plug block 41 and the metal plug rod 35 are in a perpendicular relationship with each other, thereby constraining the freedom of the cross plug block 41, so that the metal plug rod 35 forms an interlocking relationship with the cross plug block 41 and the guide sleeve 32 under the elastic force of the spring sheet 31, thereby realizing the fixed splicing between the first trim panel 1 and the second trim panel 2. When disassembly is required, repeat the above steps and pull the cross plug block 41 out of the limit groove 43 to complete the non-destructive disassembly operation, so as to facilitate recycling and reuse, save the cost of multiple uses, and also facilitate the simple and quick replacement operation when the first trim panel 1 or the second trim panel 2 is damaged.

[0038] In this embodiment, the female lock assembly 3 also includes a stopper sleeve 33 arranged opposite to the guide sleeve 32. One end of the metal insert rod 35 passes through the through groove 42 and is plugged into the slot 36 provided on the stopper sleeve 33. With such a design, when the first decorative panel 1 and the second decorative panel 2 are assembled, the metal insert rod 35 is reset under the elastic force of the spring sheet 31 and is inserted into the slot 36 on the stopper sleeve 33 after passing through the through groove 42, thereby strengthening the structural strength of the metal insert rod 35, improving the interlocking firmness and structural strength between the cross block 41 and the metal insert rod 35, and improving the firmness of the connection between the first decorative panel 1 and the second decorative panel 2 and the resistance to external force.

[0039] In this embodiment, the mother lock assembly 3 is evenly distributed between the first enclosure 5 and the first trim panel 1 along the circumference of the first enclosure 5, and the sub-lock assembly 4 is evenly distributed outside the second enclosure 6 along the circumference of the second enclosure 6. Such a design allows a second trim panel 2 to be installed in four directions around a first trim panel 1 when the first trim panel 1 and the second trim panel 2 are spliced ​​and installed with each other. In each direction, the first trim panel 1 and the second trim panel 2 are alternately arranged and assembled in sequence, so that a plane can be quickly covered, thereby improving the efficiency of laying the first trim panel 1 and the second trim panel 2 on the plane.

[0040] In this embodiment, the transverse plug block 41 matches the limiting groove 43, the metal plug rod 35 matches the through groove 42, the sub-lock assembly 4 corresponds to the mother lock assembly 3, the limiting groove 43 is located between the guide sleeve 32 and the stop sleeve 33, and the two are arranged relatively, so that when the first decorative plate 1 and the second decorative plate 2 are spliced, it is possible to not affect the insertion of the transverse plug block 41 into the limiting groove 43, and after the transverse plug block 41 is plugged in, the metal plug rod 35 can penetrate the through groove 42 on the transverse plug block 41 in a direction perpendicular to the transverse plug block 41, and one end of the metal plug rod 35 can be inserted into the through groove 42 on the transverse plug block 41 It is precisely inserted into the slot 36 on the baffle sleeve 33 to limit the free end of the metal rod 35, so that the metal rod 35 and the cross-insertion block 41 are interlocked and fixed, reducing the difficulty of assembling the first trim panel 1 and the second trim panel 2, improving the assembly efficiency, and being able to improve the connection firmness and stability between the first trim panel 1 and the second trim panel 2. After installation, it can have strong resistance to external forces, avoiding the connection firmness between the first trim panel 1 and the second trim panel 2 being easily affected by the action of forces other than magnetic force.

[0041] In this embodiment, the first trim panel 1 is consistent with the second trim panel 2, and the first enclosure 5 is located at the boundary of the first trim panel 1. Since the first trim panel 1 and the second trim panel 2 are also consistent, when the two are assembled, after the mother lock assembly 3 and the child lock assembly 4 are interlocked, the relative surfaces of the first enclosure 5 and the second enclosure 6 are in a state of conflict and alignment, so as to avoid affecting the installation neatness of the first trim panel 1 and the second trim panel 2 in the other three directions.
