DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Example

[0032] See Figures 1 to 4 As shown, a support frame mounted downlight structure comprises a downlight body 1 and a mounting surface ring 2, and a support frame mounting structure 3 is fixed on the symmetrical side surface of the mounting surface ring; in this embodiment, the downlight body and the mounting surface ring are both structures of the prior art, so they are not described in detail;

[0033] In actual application, the support frame mounting structure includes a mounting plate 31, a cross-shaped threaded rod 32, a spring 33, a torsion spring 34 and two support frames 35; during installation, the mounting plate is fixed to the side of the mounting surface ring by a screw; a convex plate 4 is provided on the upper part of the outer side surface of the mounting plate; the cross-shaped threaded rod passes through the bottom surface of the mounting surface ring and the two support frames and is threadedly connected to the convex plate; the torsion spring is sleeved on the cross-shaped threaded rod and its two ends are respectively abutted on the two support frames; a locking groove 5 is provided on the inner side surface of the support frame; one end of the spring is inserted into the locking groove for positioning, and the end edge of the spring abuts on the cross-shaped threaded rod; when the two support frames are expanded or reset in a V shape with the cross-shaped threaded rod as the center, the end edge of the spring abuts on the cross-shaped threaded rod for positioning. In this embodiment, the spring is provided to cooperate with the two support frames, which can improve the stability and reliability of the installation, and can also increase the load-bearing performance;

[0034] During installation, the cross-shaped threaded rod can be operated from the bottom of the mounting surface ring by a screwdriver to return the two support frames to the bottom, and then pressed into a closed state with both hands, and then inserted into the mounting hole of the ceiling. After the external force is released, the two support frames will expand into a V shape under the action of the torsion spring. At this time, the body of the downlight is still in a loose state. Since the spring piece is an arc-shaped curved part corresponding to the thread groove of the cross-shaped threaded rod and arranged downward, it cannot be removed under normal circumstances, thereby ensuring the stability and reliability of the installation, and also improving the overall load-bearing performance;

[0035] When disassembly is required, use a screwdriver to operate the cross-shaped threaded rod from the bottom surface of the mounting surface ring to put the cross-shaped threaded rod in its initial state, and then use both hands to press the two support frames from the hollow part of the mounting surface ring to a closed state to achieve automatic detachment. The operation is convenient and practical.

[0036] In actual application, a V-shaped retaining groove 6 is provided on the end edge of the spring sheet, and one end of the V-shaped retaining groove is an arc-shaped curved portion 7 bent downward; the cross-shaped threaded rod is pressed into the V-shaped retaining groove to limit the position. The spring sheet is arranged in an L shape; a locking piece 10 is provided on the spring sheet; the spring sheet is locked into the locking groove and is pressed and positioned by the locking piece. In this embodiment, through the above-mentioned spring sheet structure, it can be locked into the locking groove to improve the convenience of installation and the stability and reliability of installation, and at the same time, it can also ensure the effectiveness of the use of the spring sheet, and it is highly practical.

[0037] In actual application, there are C-shaped grooves 8 on the sides of the two support frames, the middle part of the cross-shaped threaded rod is inserted into the C-shaped groove, and the torsion spring is in the concave area of ​​the C-shaped groove. Through the above structure, the stability and effectiveness of the installation of the two support frames can be guaranteed.

[0038] A positioning connecting plate 9 is fixed to the top surface of the mounting surface ring; the mounting plate is attached to the inner surface of the positioning connecting plate and fixed by screws. The thickness of the support frame matches the thickness of the positioning connecting plate; through the above structure, when the support frame is reset, the outer surface of the support frame and the edge of the mounting surface ring are in the same plane. This facilitates installation from the mounting hole of the ceiling, improves the smoothness of installation, and improves the convenience and effectiveness of installation.

[0039] The utility model has positive effects: the structure of the utility model is reasonably arranged, and its support frame installation structure includes a mounting plate, a cross-shaped threaded rod, a spring sheet, a torsion spring and two support frames. It is not only convenient to disassemble and assemble, but also conducive to maintenance operations. In addition, it is provided with a spring sheet, which can make the two support frames rotate and expand into a V shape or reset with the cross-shaped threaded rod as the center under the action of external force, and the spring sheet is abutted against the cross-shaped threaded rod for pressing and positioning, which can not only improve the convenience of installation, but also improve the overall load-bearing performance, and can also ensure the stability and reliability of installation, with strong applicability and good practicality.

[0040] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components recorded in the specification can also be directly processed according to existing technical common sense. At the same time, the connection method of each component adopts the mature conventional means in the prior art, and the machinery, parts and equipment all adopt the conventional models in the prior art, so no specific description will be given here.

[0041] Obviously, the above embodiments of the present invention are merely examples for clearly explaining the present invention, and are not intended to limit the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. However, these obvious changes or modifications derived from the essential spirit of the present invention still belong to the protection scope of the present invention.
