[0025] A docking slot 7 is provided on the positioning protrusion 5, and snap-in slots 8 are provided on the side of the lower shell 1 and on both sides of the docking slot 7, and the snap-in slot 8 is connected with the accommodating slot, and a contact frame 9 corresponding to the accommodating cavity 3 is extended from the bottom end of the upper cover 2, and a snap-in column 10 is protruded outward from the side of the abutting frame 9 and snap-fitted with the snap-in slot 8, and a making way slot 11 is provided on the side of the abutting frame 9 and makes way for the positioning protrusion 5, and a docking protrusion 12 is extended from the bottom end of the upper cover 2 and on the making way slot 11 and is plugged into the docking slot 7, and the docking protrusion 12 is protruded from the abutting frame 9.

[0026] In the technical solution of the utility model, a docking slot 7 is provided at the central position of the two side edges of the lower shell 1, and a snap-in slot 8 is provided on both sides of the docking slot 7, so that one snap-in slot 8 on the same side is close to the front end position of the lower shell 1, and the other snap-in slot 8 is close to the rear end position of the lower shell 1, and a corresponding snap-in column 10 and a docking protrusion 12 are provided at the bottom end of the upper cover 2, so that during the production and assembly process, the upper cover 2 and the lower shell 1 can be connected and positioned with each other through the plug-in cooperation of the docking protrusion 12 and the docking slot 7, and the upper cover can be connected and positioned with each other through the snap-in cooperation of the snap-in column 10 and the snap-in slot 8. 2 is connected and fixed with the lower shell 1, and the docking protrusion 12 is convexly arranged on the abutting frame 9, so that the cooperation between the docking protrusion 12 and the docking slot 7 can take precedence over the cooperation between the clamping column 10 and the clamping slot 8, so that the connection between the upper cover 2 and the lower shell 1 can be accurately docked first and then fixed. Furthermore, by convexly providing a positioning protrusion 5 at the position of the docking slot 7 on the side of the lower shell 1, combined with the corresponding positioning groove 6 on the circuit board 4, the circuit board 4 can be quickly positioned through the docking cooperation between the positioning protrusion 5 and the positioning groove 6. In summary, the fixed hard disk can be fixed without the use of tools, thereby achieving high production and assembly efficiency.

[0027] In the embodiment of the utility model, the clamping groove 8 includes a guide groove 13 and a limit groove 14 arranged in sequence from top to bottom, and the guide groove 13 and the limit groove 14 are connected to each other, wherein the guide groove 13 is located at one end of the groove and gradually decreases in diameter toward the end of the guide groove 13 connected to the limit groove 14, so that the guide groove 13 is located at one end of the connected limit groove 14 to form a limit opening 15 acting on the clamping column 10.

[0028] By dividing the snap-fitting groove 8 into a guide groove 13 and a limiting groove 14 which are connected from top to bottom, and combining the setting of the guide groove 13 gradually reducing its diameter to form the limiting opening 15, when the upper cover 2 is docked with the lower shell 1, the snap-fitting column 10 can quickly enter the guide groove 13 through the guiding effect of the guide groove 13, and through the elastic snap-fitting with the limiting opening 15, that is, under the action of external force, the limiting opening 15 undergoes elastic deformation (elastic deformation provided by the material of the plastic product itself), allowing the snap-fitting column 10 to pass through the limiting opening 15 and enter the limiting groove 14, thereby completing the connection and fixation between the upper cover 2 and the lower shell 1.

[0029] The clamping groove 8 is in a dovetail shape, and the limiting groove 14 is in an arc shape corresponding to the clamping column 10 .

[0031] By setting the expansion mouth 16, the limiting opening 15 can obtain more space allowing itself to undergo elastic deformation, so that the diameter of the limiting opening 15 can be smaller, thereby effectively preventing the clamping column 10 from being easily separated from the limiting groove 14, effectively ensuring the firmness of the connection between the upper cover 2 and the lower shell 1; and by the setting that the inner side wall of the guide groove 13 can be connected to the inner side wall of the limiting groove 14, and the outer side wall of the guide groove 13 can be separated from the outer side wall of the limiting groove 14, not only effectively allowing the limiting opening 15 to obtain more space allowing itself to undergo elastic deformation, but also effectively ensuring the connection strength between the guide groove 13 and the limiting groove 14.
