Novel computer desk

[0015] The front panel (1), the vertical board (3), and the lining board (13) are rectangular and are made of wood or fiberboard. They are glued and wood screws to form the main body of the table. The keyboard is placed on one side of the middle vertical board (3) The drawer of (101) is composed of a drawer plate (8) and a drawer panel (11), and the drawer is connected to the vertical plate (3) through a sliding rail (2) and maintains a relatively movable positional relationship. Two brackets (12) for the keyboard (101) are arranged in parallel on the drawer plate (8). The brackets (12) are rectangular rods with a small hole at one end and are installed on the drawer panel (11) by hinge support. On the side and the other end is a tenon with two shoulders symmetrical. A slot is provided in the wide plane of the tenon, and the slot direction is parallel to the small hole. The bracket (12) is connected with the lifting block (5) through the shaft pin (10) to lift The block (5) is a rectangular block part with a screw hole at one end and a concave notch at the other end. The concave notch end is also provided with a small hole for mounting the shaft pin (10), the concave notch and the tenon of the bracket (12) The bracket (12) is inserted into the concave notch of the lifting block (5), and the shaft pin (10) is inserted into the small hole and slot hole, so that the bracket (12) and the lifting block (5) are around the shaft pin (10) While rotating, the shaft pin (10) can still slide relatively along the groove of the tenon. The stud (4) is in a stepped shape, with threads at both ends, the large end thread is engaged with the screw hole of the lifting block (5), the diameter of the middle smooth circle section is in clearance fit with the installation hole of the drawer plate (8), and the gasket (6), Install the lock nut (7) and the lifting knob (9) on the drawer plate (8). The function of the lock nut (7) is to adjust the axial movement between the stud (4) and the drawer plate (8) And lock the lifting knob (9) on the stud (4). After the installation is ready, the lifting block (5) can be moved up and down by rotating the lifting knob (9), thereby driving one end of the bracket (12) to correspondingly lift, so as to meet people's requirements for different inclination of the keyboard (101). On the other side of the middle vertical plate (3), a mouse support plate (17) is set. Using the principle of parallelogram mechanism, the mechanism is deduced into hinge support (14), hinge support rod (15), adjusting nut (16), T The structure of the shaped screw (18), hinge support plate (19), hand wheel (20), and slide groove (21) enables the support plate (17) to be adjusted up and down properly. The pallet (17) is a rectangular flat plate, which is connected to the panel (1) by a hinge (14) and a hinge rod (15), and is usually arranged in parallel with the panel (1). The hinge rods (15) on both sides of the front end of the pallet are In a split structure, the upper half and the lower half are provided with reverse threads, which are screwed into an adjusting nut (16) provided with reverse threads. The relative length of the hinge rod (15) can be changed by rotating the adjusting nut (16). The hinge support plate (19) is provided with two front and rear hinge support holes, the front hinge support hole is hinged with the hinge support rod (15), the rear hinge support hole is hinged with the sliding groove (21) and the T-shaped screw (18), the sliding groove ( 21) Fixed on the vertical plate (3) in the middle, the T-shaped screw (18) is embedded in the arc-shaped chute (21), and can move along the chute (21) in a circular arc. The T-shaped screw (18) and the handwheel (20) Threaded connection, the arc radius of the slide groove (21) is equivalent to the front hinged support rod (15), the center setting point meets the conditions of the parallelogram mechanism, the slide groove (21) is the support plate (17) as the rod The arc trajectory of the rear fulcrum of the parallelogram mechanism of the parts, the pallet (17) will keep the horizontal state and move along the chute (21). The trajectory of the pallet (17) forms an area that moves back and forth up and down. Select the position of the pallet (17) in this area at will, and lock it with the handwheel (20). In addition, the front and back inclination angle of the support plate (17) can also be set by rotating the adjusting nut (16).
