When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

Example 1

Fig. 1 is a schematic structural diagram of a fixing mechanism of this embodiment, fig. 2 is an assembly schematic diagram of the fixing mechanism of this embodiment, and with reference to fig. 1 and fig. 2, a fixing mechanism is used for fixedly mounting an elastic member of a lamp, and the fixing mechanism includes a housing 1 and an elastic member 2, where the elastic member 2 may be a spring such as a snap spring, a torsion spring, or the like, having a mounting arm, a torsion spring tube, and a torsion arm, so as to facilitate the lamp to be embedded and mounted in a ceiling or a suspended ceiling.

According to the configured lamp structure, the housing 1 may be a ring-shaped, cylindrical or square structural member with a cavity, and the present embodiment is described by taking a down lamp as an example, so the housing 1 is a cylindrical structure, and has a top surface 101 and a side wall 102, a joint 103 is between the top surface 101 and the side wall 102, and an outer edge 104 of the housing 1 is below the side wall 102. In order to fix the elastic element 2, the housing 1 has a limiting groove 11 at the side wall 102, and a limiting bridge 12, a limiting block 13 and a convex hull 14 are provided on the top surface 101. The stopper groove 11 is formed by recessing the side wall 102 inward at the junction 103 with the top surface 101.

As shown in fig. 1, the elastic member 2 includes a mounting arm 21, a torsion spring tube 22, and a torsion arm 23; the mounting arms 21 and torsion arms 23 are located on either side of the torsion spring tube 22 and the torsion arms 13 ride on the outer rim 104 of the housing 1. The torsion spring tube 22 is arranged in the limiting groove 11 and is abutted against the limiting groove 11 to form a first mounting position of the elastic piece and the shell; while the mounting arm 21 extends from the torsion spring tube 22 to form a closed structure having a first pull rod 211, a locking strip 212 and a second pull rod 213, which may be square, circular or oval, the square being exemplified in this embodiment. With further reference to fig. 1, the first and second tie rods 211 and 213 each have an L-shaped configuration, while the check bridge 12 is an elastic structural member provided with a slot.

It should be noted that, since the limiting bridge 12 and the top surface 101 form a closed annular structure, the limiting bridge 12 limits the mounting arm 21 of the elastic element 2 in the vertical direction, so as to form a second mounting position of the elastic element and the housing.

In the installation process, as shown in fig. 2, the torsion arm 23 is lifted to move the clip strip 212 forward toward the stopper 13 until the clip strip 212 is connected to the stopper 13 in a snap-fit manner. Card strip 212 is cylindrical metal strip, and in order to its spacing fixed, the height value of the stopper 13 of this embodiment will be more than or equal to 2/3 of card strip 212 diameter value, and card strip 212 just can not take place the displacement after with stopper 13 lock like this, under the effect of cooperation spacing groove, can realize that the front and back position on the horizontal direction is spacing to the elastic component. Thus, a third mounting position of the elastic element and the shell is formed. Of course, in order to further ensure the connection stability, in some embodiments, a groove may be further disposed at the position of the limiting block 13, so that the limiting block is matched with the clamping strip 212.

Further, in order to limit the horizontal position of the elastic member, the housing 1 is further provided with convex hulls 14 on the top surface 101, the convex hulls 14 are positioned at both sides of the limit block, and a gap 141 is left between the convex hulls 14 and the end of the limit block 13, and the first pull rod 211 and the second pull rod 213 travel along the gap 141. After the fastening strip 212 is fastened to the limiting block 13, the convex hull 14 limits the horizontal left and right positions of the elastic member, so as to form a fourth mounting position of the elastic member and the housing.

It should be further noted that, in order to better assemble the elastic element 2, the limiting groove 11, the limiting bridge 12 and the limiting block 13 are located on the same axis y together, so that the elastic element 2 is smoothly and not jammed during installation.

Elastic component 2 can set up to more than two, and the elastic component 2 of this embodiment sets up to two, and its symmetry is fixed on the opposite face of casing 1, when subsequent needs are installed lamps and lanterns, and torsion arm 23 alright joint through two elastic components is on ceiling or furred ceiling, accomplishes the embedded installation of lamps and lanterns.

On this structure basis, accomplished the fixed mounting of elastic component 2 on casing 1, it is convenient that this inserts buckled fixed mode installation, and structural stability is good, has promoted the assembly efficiency of spring in the recessed lamp moreover.

Example 2

Fig. 3 is an exploded view of the fixing mechanism of the present embodiment, fig. 4 is a cross-sectional view of the fixing mechanism of the present embodiment, and with reference to fig. 3 and fig. 4, the fixing mechanism of the present embodiment is additionally provided with an upper cover 3 on the basis of the fixing mechanism of embodiment 1, the upper cover 3 is fixed above the housing 1, and a cavity 30 is provided between the bottom surface of the upper cover 3 and the top surface of the housing.

In addition, the upper cover 3 is further provided with a stopper 31 downward, and the stopper 31 is provided with a through hole 32. The stopper leg 31 of the present embodiment covers the stopper groove 11, and the torsion arm 23 and a part of the torsion spring tube 22 protrude from the through hole 32.

After the elastic member 2 is mounted to the housing 1, the upper cover 3 is snap-coupled to the housing 1, thereby ensuring structural integrity.

Example 3
