Multi-purpose desk lamp capable of adjusting illumination position

A multi-purpose desk lamp capable of adjusting illumination position,

• comprising a base, a support column, a luminous lampshade and a light emitting component, wherein,
• at least one press button being configured on a surface of the base;
• a bottom end of the support column being flexibly connected with a top of the base through a movable disk;
• the luminous lampshade being flexibly connected with a top end of the support column through a pivot structure, the luminous lampshade being composed of a top shell and a bottom cover box, wherein the top shell having a hollow bottom with a plurality of clamping slots disposed on inner edges of two sides of the hollow bottom, and an inner space of the top shell being configured with a plurality of long hole columns extending downward;
• the bottom cover box and the top shell corresponding to each other, outer edges of two sides of a bottom of the bottom cover box being configured with a plurality of tenons, wherein the tenons being configured correspondingly to the clamping slots, a space defined by a peripheral wall near to an outer edge of a top surface of the bottom cover box, the top surface disposed with assembly holes corresponding to the long hole columns, when the top shell covers the bottom cover box, the long hole columns of the top shell one by one correspond to the assembly holes of the bottom cover box and further connect with the long hole columns via assembly components passing through the assembly holes, and meanwhile, the clamping slots of the top shell being correspondingly engaged with the tenons of the bottom cover box, the light emitting component being configured inside an inner space of the bottom cover box, the light emitting component being controlled by the at least one press button to light up, light out or adjust a variety of lighting modes;
• an inner bottom of the bottom cover box being configured with a grille to enhance a light gentleness and an anti-glare function, wherein an open slot disposed on a top surface of the top shell is closed toward one end, a short hole column respectively disposed inside the inner space of the top shell is closed toward the open slot and on a middle section;
• the luminous lampshade having a telescopic sliding structure, comprising
• a positioning seat, an upper-layer frame, a lower-layer frame, a buffer frame and a lower positioning plate, wherein,
• the positioning seat being designed as a three-dimensional frame with left and right sides communicating with each other, a bottom extending toward the left and right sides to form a panel with a larger area, a big through-hole being disposed on a center of the bottom, a small through-hole being disposed on a top surface, the panel formed by extending the bottom toward the left and right sides which are disposed with a plurality of assembly holes, a positioning bolt passing through the entire positioning seat through the big through-hole from down to up, then through the small through-hole, and further through the open slot of the top shell, thereby securely connecting with the positioning bolt by a stop nut to enable the positioning seat to be suspended under the open slot of the top shell;
• a plate body of the lower positioning plate being disposed with a plurality of assembly holes, and front and rear sides extending upward to form a S-shaped side wall, when assembled, the lower positioning plate penetrating and reaching inside the positioning seat and horizontally resting on the panel formed by extending the bottom of the positioning seat toward left and right sides, and then to be secured via an assembly component passing through the assembly hole of the positioning seat and the assembly hole of the lower positioning plate, thereby enabling the lower positioning plate to be rested horizontally on the bottom of the positioning seat;
• the buffer frame being a cover shape having a hollow bottom and front and rear sides extending vertically downward to form side walls, the side walls being disposed with a series of buffer holes, the buffer frame being longer than the lower positioning plate, when assembled, the buffer frame penetrating and resting inside the positioning seat and covering the lower positioning plate, thereby enabling top ends of the S-shaped side walls on two sides of the lower positioning plate to be respectively against a top edge inside the side walls on two sides of the buffer frame to form a state in which the lower positioning plate supports the buffer frame, so that the buffer frame is capable of sliding left and right in relation to the lower positioning plate;
• the lower-layer frame being a cover shape having a hollow bottom and front and rear sides extending vertically downward to form a S-shaped side wall, one side extending vertically downward to form a limiting wall, an assembly hole being respectively disposed on a plate surface of the lower-layer frame at a position close to two ends thereof, the lower-layer frame being longer than the buffer frame, when assembled, the lower-layer frame penetrating and resting inside the positioning seat and covering the buffer frame, thereby enabling the top edges of the side walls on two sides of the buffer frame to be respectively against the top edges inside the S-shaped side walls on two sides of the lower-layer frame to form a state in which the buffer frame supports the lower-layer frame;
• and
• the upper-layer frame being a cover shape having hollow left and right sides and a hollow bottom, the front and rear sides thereof extending vertically downward to form side walls, an inner assembly hole and an outer assembly hole being respectively disposed on a plate surface of the upper-layer frame at a position close to two ends thereof, the upper-layer frame being longer than the lower-layer frame, when assembled, the upper-layer frame penetrating and resting inside the positioning seat and covering the lower-layer frame, then being secured via an assembly component passing through the inner assembly hole of the upper-layer frame and the assembly hole of the lower-layer frame, and meanwhile, an assembly component passing through the outer assembly hole of the upper-layer frame and being correspondingly secured with the short hole column inside the top shell, thereby enabling a middle-layer frame and the upper-layer frame to being securely connected with the top shell.
