DETAILED DESCRIPTION

[0019] In the embodiment, refer to Figures 1-4The core assembly strength higher CD player, including the shell 1 and the core 4, the shell 1 has CD warehouse 3, CD warehouse 3 is provided with CD door 2;In the shell 1 in the position of CD warehouse 3 is provided with several screw columns, the core 4 is fixed on the screw column through screw 7;Screw column body 51 is provided with a ring bone 53 outside the periphery, the height of ring bone 53 is lower than the column body 51;Between ring bone 53 and column body 51 is provided with several connecting bones 52, the ring bone 53 and column body 51 are connected into a whole by connecting bone 52 to form ring skeleton screw column 5, and the ring bone 53, connecting bone 52 and column body 51 are connected into a whole structure with the shell 1, so that the column body 51 is strengthened and fixed by double structure, and the bottom is locked by the ring of reinforcing force and is difficult to be pulled off.

[0020] The ring bone 53 is a circular structure, and the height thereof is not more than half of the column body 51, so that the core 4 is not interfered during installation.

[0021] The connecting bone 52 includes three (as shown in Figure 5 or four (as shown in Figure 6 The connecting bone 52 is arranged at uniform intervals, and the three connecting bones 52 are arranged at an angle of 120 degrees, and the four connecting bones 52 are arranged in a cross shape.

[0022] The ring skeleton screw column 5 includes at least two, and the ring skeleton screw column 5 is arranged on the planar area of the shell 1. If the positions of the core 4 to be installed are all planar areas, the ring skeleton screw column 5 can be used.

[0023] For the case that the side inclined surface of the shell 1 needs to be occupied, the cross skeleton screw column 6 is arranged near the side inclined surface of the shell 1, and the cross skeleton 61 is arranged outside the column body of the cross skeleton screw column 6. This is mainly because it is difficult to form a ring bone on the inclined surface, so the ring skeleton screw column 5 is used in combination with the cross skeleton screw column 6, which is beneficial to balance the installation strength of the core 4 and the process cost.

[0024] The end of the cross skeleton 61 connected with the side inclined surface of the shell 1 extends outward to form a reinforcing portion 62, and the reinforcing portion 62 is connected with the side inclined surface of the shell 1, so as to improve the structural strength of the cross skeleton screw column 6.

[0025] The position near the cross skeleton screw column 6 in the shell 1 has a protruding portion 11, and the cross skeleton 61 of the cross skeleton screw column 6 near the protruding portion 11 is connected with the protruding portion 11, so as to further improve the structural strength of the cross skeleton screw column 6 and increase the difficulty of breaking the cross skeleton screw column 6.

[0026] The utility model has been described in detail above, the above-mentioned are only the preferred embodiment of the utility model, and cannot limit the utility model implementation range, namely, all equal changes and modifications made according to the scope of the application should still belong to the utility model coverage.
