[0021] The present invention is further described in detail below in conjunction with the accompanying drawings. In the description of the present invention, it should be understood that the directions or positional relationships indicated by directional words such as "upper, lower" and "top, bottom" are usually based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description. Unless otherwise stated, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present invention; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0022] like Figure 1-5 As shown, a conversion frame for external use of an LED lamp comprises a main frame 1 and an end frame 2, wherein the main frame is U-shaped, the end frame is arranged opposite to the opening of the main frame, and hangers 3 are fixedly installed on both sides of the opening of the main frame; and mounting holes are arranged on the hangers;

[0023] Both sides of the opening of the main frame are bent inwardly and extended to form a bracket 4, and the bracket is penetrated by a through hole 5; the mounting hole is located in the inner side of the bracket in the vertical direction to avoid interference with the bracket;

[0024] The two sides of the end frame are installed with a card plate 6 through a rotating reset structure, and a card block 7 is fixed to the outer end of the card plate. The card plate is plugged into the through hole, and a card slot 8 is opened on the main frame body to be engaged with the card block.

[0025] In this way, during installation, the main frame is fixed on the ceiling through the hanger. After the flat panel light is connected, the flat panel light is inserted into the main hanger from the opening of the main frame. The bracket supports the flat panel light, and finally the end frame is installed at the opening of the main frame. When installing the end frame, the card plate is rotated to face the perforation of the bracket, and the card plate is inserted into the perforation. Under the action of the rotation reset structure, the card block on the outside of the card plate is inserted into the card slot to complete the connection. When disassembly is required, the card block is pushed inward, and the card block is disengaged from the card slot, and the card plate can be taken out from the bracket to realize the disassembly of the end frame.

[0026] During implementation, the rotation reset structure includes a connection block 9 fixedly connected to the end frame, a rotating shaft is fixedly installed on the connection block, the card plate is provided with an axial hole for rotating with the rotating shaft, the upper end of the rotating shaft is threadedly connected with a pressure block, and the rotation reset structure also includes a torsion spring 10, the two ends of which are respectively fixedly connected to the end frame and the card plate. The torsion spring is provided to provide a torque for the card plate to rotate outward, so that the card block can be better connected with the card slot. The pressure block is provided to limit the card plate to prevent the card plate from being separated from the rotating shaft.

[0027] During implementation, the outer side of the clamping plate has an arc surface. Through the setting of the arc surface, when the end frame needs to be disassembled, the end frame is pulled outward, and the clamping block can be separated from the clamping slot under the action of the arc surface and the rotation reset structure.

[0028] During implementation, guide plates 11 are fixedly installed on both sides of the end frame, the guide plates are spaced apart from the card plate, a plurality of guide grooves 12 are provided on the guide plates, and ribs 13 are provided on the through holes of the bracket to slide with the guide grooves. The guide plates provide a support effect for the end frame.

[0029] During implementation, the inner end of the guide plate is rounded to facilitate better insertion of the guide plate into the perforation.

[0030] During implementation, magnets 14 are fixedly installed on the outside of the openings of the main frame on both sides. The magnets are annular. A through hole is provided through the inner hole of the main frame facing the magnet. The cardboard is provided with a plug hole 5 and an iron plug pin 16. The plug pin passes through the magnet and the through hole and is plugged into the plug hole. The plug pin is attracted to the magnet. The cardboard can be limited by the setting of the plug pin. When it needs to be disassembled, the plug pin can be pulled out. The magnet can attract the plug pin to fix the position of the plug pin.

[0031] Finally, it should be noted that those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include these modifications and variations.
