Assembling structure for portable memory device

Claim 2

Assembling structure for portable memory device, comprising: a memory device main body, one end of the main body being provided with a projecting adapter, middle portions of two sides of the main body being respectively formed with two lateral projecting blocks; and a sheath, a first end of which is formed with an opening for placing the main body therein, a second end of the sheath is formed with a through hole through which the projecting adapter outwardly protrudes, middle portions of two sides of the sheath are respectively formed with two inwardly extending stop boards for stopping the lateral projecting blocks of the main body from slipping out, whereby the main body is reciprocally slidable within the sheath and the projecting adapter can be extended out from the through hole of the sheath or retracted therein.

Claim 3

Assembling structure for portable memory device as claimed in claim 1 , wherein the main body is composed of a bottom cover, an upper cover and a circuit board, the bottom cover being a casing having a central depression, one end of the bottom cover being formed with a radially expanded arch edge, two corners of the other end being formed with recessed sections, a projecting arch edge being formed on each recessed section and adjacent to the periphery of the opening of the bottom cover, two lateral projecting blocks being respectively formed on two sides of the bottom cover, a thread hole being formed at the center of the expanded arch edge, a memory module and relevant circuits being received in the circuit board, one end of the circuit board being formed with a through hole, while the other end thereof having an extending adapter, the upper cover being also a casing having a central depression, one end of the upper cover being formed with a through hole and an expanded arch edge respectively corresponding to the thread hole and expanded arch edge of the bottom cover, the middle of the other end of the upper cover being formed with a dent, two corners of the end of the upper cover being formed with projecting hook boards corresponding to the recessed sections, whereby the hook boards of the upper cover are inserted into the recessed sections of the bottom cover and hooked on the projecting arch edges to fix one end of the bottom cover and the upper cover, the adapter of the circuit board extending out of the dent of the upper cover, a bolt being passed through the through holes of the upper cover and the circuit board and screwed into the thread hole of the bottom cover, whereby the other end of the bottom cover and the upper cover is firmly connected to clamp the circuit board.

Claim 4

Assembling structure for portable memory device as claimed in claim 2 , wherein the memory device main body further comprises a lateral decorative strip which is an arched strip, an inner side thereof being formed with multiple hook sections having opening facing downward for hooking the periphery of the expanded arch edge of the bottom cover, the periphery of the expanded arch edge of the upper cover being formed with multiple notches corresponding to the hook sections of the lateral decorative strip, the hook sections of the lateral decorative strips being respectively hooked on the expanded arch edge of the bottom cover and received in the notches of the upper cover, whereby when the upper cover is connected with the bottom cover, the mating faces thereof are snugly adjoined and the lateral decorative strip covers the seam between the upper cover and the bottom cover.

Claim 5

Assembling structure for portable memory device as claimed in claim 2 , wherein two lateral projecting blocks are formed on two sides of the upper cover corresponding to the lateral projecting blocks of the bottom cover.

Claim 6

Assembling structure for portable memory device as claimed in claim 3 , wherein two lateral projecting blocks are formed on two sides of the upper cover corresponding to the lateral projecting blocks of the bottom cover.

Claim 7

Assembling structure for portable memory device as claimed in claim 2 , wherein a shift switch is disposed on one side of the circuit board for controlling the execution of writing of the memory module, the upper cover being formed with a lateral notch corresponding to the shift switch and the sheath being also formed with a lateral opening corresponding to the shift switch, whereby the shift switch protrudes from the lateral notch and the lateral opening and is exposed to outer side.

Claim 8

Assembling structure for portable memory device as claimed in claim 3 , wherein a shift switch is disposed on one side of the circuit board for controlling the execution of writing of the memory module, the upper cover being formed with a lateral notch corresponding to the shift switch and the sheath being also formed with a lateral opening corresponding to the shift switch, whereby the shift switch protrudes from the lateral notch and the lateral opening and is exposed to outer side.

Claim 9

Assembling structure for portable memory device as claimed in claim 2 , wherein the middle portion of the bottom cover or upper cover of the main body is formed with at least one projecting block, an inner side of the sheath being formed with a guide channel corresponding to the projecting block, whereby the projecting block is inlaid in the guide channel to guide the main body to slide within the sheath.

Claim 10

Assembling structure for portable memory device as claimed in claim 3 , wherein the middle portion of the bottom cover or upper cover of the main body is formed with at least one projecting block, an inner side of the sheath being formed with a guide channel corresponding to the projecting block, whereby the projecting block is inlaid in the guide channel to guide the main body to slide within the sheath.

Claim 11

Assembling structure for portable memory device as claimed in claim 1 , wherein at least one hook hole is formed on one end of the main body extending out from the opening of the sheath for a string or a key ring to pass therethrough and tied.

Claim 12

Assembling structure for portable memory device as claimed in claim 1 , wherein the adapter is a USB plug.
