The shape of the shell 1 is matched with that of the 86 bottom box, and the shell 1 can be fixed in the 86 bottom box through screws, so that the front of the shell is basically level with a wall, and the attractiveness of interior decoration is ensured.

The static contact 2 comprises a live wire static contact and a zero line static contact, the commercial power connecting end 3 comprises a live wire connecting end and a zero line connecting end, and the commercial power connecting end is correspondingly and electrically connected with the static contact 2. The static contact 2 is arc-shaped or bar-shaped (shown in fig. 2) and comprises an upper part and a lower part, and a movable contact insertion gap (shown in fig. 3) of the electric appliance is formed between the upper part and the lower part. The utility power connecting end 3 is a screw fixed type wire column slot, and a stop block is arranged at the tail end of the wire column slot, so that potential safety hazards such as contact between a zero wire and a fire wire caused by too long extension of an inserted bare wire out of the wire column slot can be effectively avoided.

As shown in fig. 5 to 9, the lamp (such as a down lamp, a flying saucer lamp, etc.) matched with the screwing lamp cap includes a fixed shaft 41 and a movable contact piece 42, wherein the movable contact piece 42 is vertically fixed on the side surface of the fixed shaft 41, the fixed shaft 41 is fixed above the lamp 4, and the movable contact piece 42 is electrically connected with a light-emitting element in the lamp 4 through a conductor inside the fixed shaft 41. The fixed shaft 41 and the movable contact piece 42 can be inserted into the screwing lamp holder through the rectangular hole 11 formed in the front of the shell 1, and the movable contact piece 42 can correspondingly contact the static contact piece 2 to form electric connection by rotating around the fixed shaft 41.

The lamp 4 is further provided with a first rotating block 43, the first rotating block 43 is rotatably arranged on the lamp 4 around the first fixed shaft 41, and the first rotating block 43 is provided with a groove (non-through hole) for accommodating the first movable contact piece 42. The upper part of the first rotating block 43 is rotatably connected with the top end of the first fixed shaft 41, the middle part of the first rotating block 43 is provided with a gap for accommodating the first fixed shaft 41, the lower part of the first rotating block is fixed on a rotary table 44, the rotary table 44 is rotatably arranged on the lamp 4 around the axis of the first fixed shaft 41, and the circumference of the rotary table 44 is provided with a notch 441 as shown in fig. 9. The lamp 4 is provided with a button 45, the lower end of the button 45 is connected with a guide rod 46, the lower end of the guide rod 46 is hinged with one end of a warping rod 47, the middle part of the warping rod 47 is hinged on the lamp 4, the hinged part of the warping rod 47 and the lamp 4 is provided with a torsion spring 48, and the other end of the warping rod 47 is bent to be in a hook shape. The hook-shaped end of the tilting lever 47 can be automatically inserted into the notch 441 of the turntable 44 to lock the turntable 44 under the elastic torsion force of the torsion spring 48. The recess 441 is disposed on the turntable 44, so that the angle between the first rotating block 43 and the first movable contact 42 is 90 ° when the turntable 44 is locked.

The invention has the use process and working principle:

when the lamp 4 is not in use, the first rotating block 43 is rotated to the same angle position as the first movable contact piece 42, so that the first movable contact piece 42 is hidden in the groove on the first rotating block 43, and the first movable contact piece 42 is prevented from being collided and damaged. The lamp 4 is very fast to install and use, the first rotating block 43 is inserted into the rectangular hole 11 of the lamp cap shell, and the lamp is rotated by 90 degrees according to the set direction. The first rotating block 43 (and the turntable 44 fixed thereto) is held in place by the rectangular aperture 11. The movable contact piece 42 (and the fixed shaft 41 fixed with the movable contact piece) rotates 90 degrees along with the lamp 4, so that the movable contact piece 42 and the rotating block 43 are in a vertical state and contact with the static contact piece 2 (inserted into a gap formed by the upper part and the lower part of the static contact piece 2), and the electric connection between the movable contact piece 42 and the static contact piece 2 is formed. At this time, the hook-shaped end of the tilting lever 47 is automatically inserted into the recess 441 of the turntable 44 under the elastic torsion force of the torsion spring 48, and the turntable 44 and the first rotating block 43 are locked to be unable to rotate freely. Thus, the first movable contact piece 42 is contacted and clamped with the fixed contact piece 2 and the first rotary block 43 is contacted and clamped with the rectangular hole 11 to form a stable cross connection. Good electrical and physical connection can be formed only by inserting and rotating 1/4 circle, and the installation and the use are convenient and the connection is more stable and reliable compared with the traditional screw socket and hanging lamp cap.

When the rotary table 44 is detached or replaced, the button 45 is pressed to lift the hook-shaped end of the seesaw rod 47, so that the hook-shaped end is separated from the notch 441 of the rotary table 44. Then, the lamp is reversely rotated by 92 degrees, and the movable contact piece I42 and the rotary block I43 are rotated to the same angle (the same angle position as the rectangular hole 11 of the shell 1), so that the lamp can be removed from the lamp cap (in the rectangular hole 11).

The invention is suitable for lamps such as down lamps, flying saucer lamps and the like, and is particularly used for the flying saucer lamps. Because the screwing lamp cap is arranged in the 86 bottom box, after the flying saucer lamp is connected and fixed on the screwing lamp cap according to the scheme, the flying saucer lamp can be tightly attached to a ceiling or a wall, a gap between the flying saucer lamp and the ceiling or the wall is avoided, the indoor lamp is more compact and attractive in decoration, and the indoor space occupation is reduced.

The connection principle of the lamp and the screwing lamp cap can be utilized to design a power adapter 5 matched with the lamp cap, as shown in fig. 10. The power adapter 5 matched with the screwing lamp cap comprises a shell 51, a second fixed shaft 52, a second movable contact piece 53 and a second rotary block 54. The shell 51 is provided with a power jack, the shell 51 is internally provided with a plug sheet opposite to the power jack, the second fixed shaft 52 is arranged below the shell 51, the second movable contact sheet 53 is vertically fixed on the side surface of the second fixed shaft 52, and the second movable contact sheet 53 is electrically connected with the plug sheet in the shell 51 through a conductor in the second fixed shaft 52. The second rotating block 54 is rotatably disposed on the second fixed shaft 52, and a groove for accommodating the second moving contact piece 53 is disposed on the second rotating block 54. The power supply jack can be a three-hole or two-hole jack matched with a plug of a common electrical appliance, or can be a USB jack subjected to transformation or rectification, so that the power supply jack can supply electric energy to the common electrical appliance for families and offices, or can supply power or charge for low-power electronic products and intelligent equipment.

It is intended that all such modifications, equivalents, and improvements fall within the spirit and scope of the invention.
