detailed description

Embodiment: A notebook computer rotating shaft protection cover, including a cylindrical kit 1 and a bottom plate 2, the bottom plate 2 is fixedly inserted in the cylindrical kit 1, and the inner wall of the cylindrical kit 1 and one side of the bottom plate 2 jointly form a shaft for accommodating The rotating shaft accommodating space 3 is fixedly connected by the cylindrical sleeve 1 and the bottom plate 2 to form the rotating shaft accommodating space 3 for fixing and accommodating the rotating shaft. It is dense and bright, easy to deal with various surface colors, beautiful in appearance, low in production cost, and meets environmental protection requirements.

The bottom plate 2 is located at a set depth in the cylindrical kit 1, the inner side wall of the cylindrical kit 1 and the other side of the bottom plate 2 jointly form a line accommodation space 4, and the other side of the cylindrical kit 1 and the bottom plate 2 forms a line accommodation space 4 It is used to place the lines of the laptop to avoid the lines from being scattered and damaged.

The line storage space 4 jointly formed by the inner side wall of the cylindrical kit 1 and the other side of the bottom plate 2 is also equipped with a line management device, through which the lines can be arranged to prevent them from being entangled and causing breakage or signal interference.

The cable management device is a foam tightly inserted in the circuit accommodation space 4, and a slot for circuit accommodation is formed in the foam, and the circuit arrangement is realized through the foam cable management device. The cost of the foam is low and can be tightly inserted into the In the cylindrical kit 1, it is easy to assemble, and because of its soft texture, it will not damage the circuit.

The bottom plate 2 is connected to the cylindrical kit 1 by laser welding. There is no welding material accumulation problem in this welding method, and the inner surface is smooth to avoid damage to the die-casting shaft, while maintaining the shaft accommodation space formed by the die-casting shaft, the cylindrical kit 1 and the bottom plate 2 3 perfect combination, in addition, it can also be a fixed connection such as interference fit.
