Description

Technical Field

[0001] This utility model belongs to the field of downlight technology, specifically relating to a spring mounting structure for a downlight and the downlight itself. Background Technology

[0002] Downlights are recessed lighting fixtures that project light downwards into walls. Existing downlights typically have slots on both sides of the light body to secure the ends of two spring clips, which hold the downlight to the wall. During installation, the spring clips on both sides of the downlight are inserted into pre-drilled holes in the wall, and the downlight is pushed until it is flush with the wall. The ends of the spring clips automatically spring back and lock into the wall, ensuring a secure installation. However, this method of installing the ends of the spring clips into the slots places high demands on the materials and manufacturing process of the downlight. If the downlight material is too soft or the injection molding tolerance is too large, or the gap between the slot and the side wall of the light body is too large, the ends of the spring clips may not be able to hold securely in the slot, leading to the spring clips easily coming loose when inserted. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings and deficiencies in the prior art and provide a spring mounting structure for a downlight, which limits the spring and makes the spring securely installed in the spring slot of the downlight.

[0004] This utility model is achieved through the following technical solution:

[0005] A spring mounting structure for a downlight includes a downlight housing, a spring slot, an elastic protrusion, and limiting strips. The spring slot is vertically disposed on the side surface of the downlight housing and has an opening near the top of the downlight housing. The spring slot includes a bottom wall and two opposing first and second side walls extending along the side surface of the downlight housing. The elastic protrusion is disposed on the first side wall, and a first gap for accommodating a spring clip is formed between the elastic protrusion and the bottom wall. Two limiting strips are disposed on the second side wall. The elastic protrusion projects onto the second side wall, and the two limiting strips are located on opposite sides of the projection of the elastic protrusion. The elastic protrusion extends in a direction close to the second side wall, and the distance between the elastic protrusion and the second side wall is less than the thickness of the limiting strips.

[0006] This utility model provides a spring mounting structure for a downlight. The spring slot is vertically disposed on the side surface of the downlight housing. The spring slot has an opening near the top of the downlight housing, allowing the spring clip to be installed into the spring slot from top to bottom along the opening. An elastic protrusion is disposed on the first side wall, forming a first gap between the elastic protrusion and the bottom wall to accommodate the spring clip. This allows the spring clip to be fitted onto the elastic protrusion and partially accommodated within the first gap when installed in the spring slot. Two limiting strips are disposed on the second side wall, and the two limiting strips are respectively located at... On both sides of the projection of the elastic protrusion, the elastic protrusion extends along the direction close to the second sidewall. The distance between the elastic protrusion and the second sidewall is less than the thickness of the limiting strip. When the spring clip is installed in the spring slot, the spring clip is sleeved on the elastic protrusion. The elastic protrusion limits the spring clip in the vertical direction. Since the distance between the elastic protrusion and the second sidewall is less than the thickness of the limiting strip, if the spring comes out of the gap between the elastic protrusion and the second sidewall, it will be blocked by the limiting strip, thus limiting the spring clip in the horizontal direction and preventing the spring clip from coming out of the spring slot. The spring mounting structure of the downlight provided by this utility model limits the spring clip, making the spring clip securely installed in the spring slot.

[0007] Furthermore, the elastic protrusion includes an elastic connecting portion and an elastic extension portion connected to the elastic connecting portion, the elastic extension portion protruding from the elastic connecting portion; the elastic connecting portion is connected to the first sidewall; the elastic extension portion is disposed near the bottom wall and extends towards the second sidewall, the distance between the elastic extension portion and the second sidewall is less than the thickness of the limiting strip. The elastic connecting portion is connected to the first sidewall, and the elastic extension portion is disposed near the bottom wall. When the spring clip is installed from top to bottom in the spring slot, it squeezes the elastic connecting portion, creating a space between the elastic connecting portion and the limiting strip to accommodate the spring clip. The spring clip continues to move downwards until it is fitted onto the elastic connecting portion and the extension portion. Since the distance between the elastic extension portion and the second sidewall is less than the thickness of the limiting strip, if the spring clip comes out of the gap between the elastic extension portion and the second sidewall, it will be blocked by the limiting strip, thus limiting the horizontal direction of the spring clip.

[0008] Furthermore, the elastic extension is arc-shaped; or, the elastic extension is inclined from the elastic connecting portion toward the second sidewall. The elastic extension is arranged in an arc or inclined manner to facilitate the spring clip entering the spring slot and pressing the elastic protrusion until it is fitted onto the elastic protrusion.

[0009] Furthermore, the first sidewall is disposed away from the downlight housing; a through hole is formed in the first sidewall; one end of the elastic connecting portion away from the elastic extension portion is fixed to the first sidewall, and the elastic extension portion is located within the through hole. When the spring clip is installed from top to bottom into the spring slot, it compresses the elastic connecting portion, creating a space between the elastic connecting portion and the limiting strip to accommodate the spring clip. When the elastic protrusion is compressed, the through hole provides space for the elastic protrusion to move.

[0010] Furthermore, the width of the top of the limiting strip gradually decreases along the direction close to the opening of the spring slot. When the spring clip is installed in the spring slot from top to bottom, the gradual decrease in width of the top of the limiting strip along the direction close to the opening of the spring slot facilitates the insertion of the spring clip into the spring slot.

[0011] Furthermore, the width of the middle and bottom of the limiting strip is the same, and the top end of the limiting strip near the middle has the same width as the middle portion. The equal width of the middle and bottom of the limiting strip, along with the equal width of the top end near the middle, forms a straight limiting strip that limits the movement of the spring clip.

[0012] Furthermore, a second gap for accommodating the spring is formed between the limiting strip and the first sidewall. This second gap facilitates the spring clip's entry into the spring slot.

[0013] This utility model also provides a downlight, including a spring clip and the above-mentioned spring mounting structure for the downlight; the spring clip includes a torsion spring, a mounting frame, and a snap fastener, the mounting frame and the snap fastener being fixed to both sides of the torsion spring respectively; the mounting frame is installed in the spring slot from the opening of the spring slot and sleeved on the elastic protrusion, the mounting frame part being located in the first gap formed between the elastic protrusion and the bottom wall; the snap fastener is located outside the spring slot.

[0014] In the downlight of this utility model, the spring clip is securely engaged in the spring slot by the mounting frame, and the snap fastener is located outside the spring slot, so that the snap fastener can be pushed into the reserved hole in the wall and then latch onto the wall.

[0029] Example 1

[0030] This embodiment provides a spring mounting structure for a downlight. Figure 1 This is a schematic diagram of the spring mounting structure for a downlight. Figure 2 This is a structural diagram of a downlight. Figure 3 This is the front view of the spring mounting structure of the downlight. Figure 4 yes Figure 3 Cross-sectional view along the BB direction. Figure 5 yes Figure 3 Please refer to the enlarged view at point A in the middle. Figure 1-5 The spring mounting structure of the downlight includes a downlight housing 1, a spring slot 2, an elastic protrusion 3, and a limiting strip 4. The spring slot 2 is vertically disposed on the side surface of the downlight housing 1, and has an opening near the top of the downlight housing 1. The spring slot 2 includes a bottom wall 21 and two opposing first side walls 22 and second side walls 23, which extend along the side surface of the downlight housing 1. The elastic protrusion 3 is disposed on the first side wall 22. A first gap is formed between the elastic protrusion 3 and the bottom wall 21 to accommodate the spring latch 5. There are two limiting strips 4, which are disposed on the second side wall 23. The elastic protrusion 3 forms a projection on the second side wall 23, and the two limiting strips 4 are located on both sides of the projection of the elastic protrusion 3. The elastic protrusion 3 extends in a direction close to the second side wall 23, and the distance between the elastic protrusion 3 and the second side wall 23 is less than the thickness of the limiting strip 4.

[0031] In the spring mounting structure of the downlight provided in this embodiment, the spring slot 2 is vertically disposed on the side surface of the downlight housing 1. The spring slot 2 has an opening near the top of the downlight housing 1, allowing the spring clip 5 to be installed in the spring slot 2 from top to bottom along the opening. The elastic protrusion 3 is disposed on the first side wall 22, and a first gap is formed between the elastic protrusion 3 and the bottom wall 21 to accommodate the spring clip 5, so that when the spring clip 5 is installed in the spring slot 2, it can be fitted onto the elastic protrusion 3 and partially accommodated in the first gap. Two limiting strips 4 are disposed on the second side wall 23, and the two limiting strips 4 are respectively located on the projection of the elastic protrusion 3. On both sides, the elastic protrusions 3 extend along the direction close to the second sidewall 23. The distance between the elastic protrusions 3 and the second sidewall 23 is less than the thickness of the limiting strip 4. When the spring clip 5 is installed in the spring slot 2, the spring clip 5 is sleeved on the elastic protrusions 3. The elastic protrusions 3 limit the spring clip 5 in the vertical direction. Since the distance between the elastic protrusions 3 and the second sidewall 23 is less than the thickness of the limiting strip 4, if the spring clip 5 comes out from the gap between the elastic protrusions 3 and the second sidewall 23, it will be blocked by the limiting strip 4, thus limiting the spring clip 5 in the horizontal direction and preventing the spring clip 5 from coming out of the spring slot 2. The spring mounting structure of the downlight provided in this embodiment limits the spring clip 5, so that the spring clip 5 is securely installed in the spring slot 2.

[0032] In the spring clip mounting structure of the downlight provided in this embodiment, since the spring clip 5 is limited in the vertical and horizontal directions by the elastic protrusion 3 and the limiting strip 4 respectively, and there is a gap between the elastic protrusion 3 and the second side wall 23, the requirements for injection molding precision in the prior art are reduced. It is only necessary to control the gap between the elastic protrusion 3 and the second side wall 23 and the gap being less than the thickness of the limiting strip 4. It also reduces the requirements for the hardness of the downlight housing 1 material.

[0033] Figure 6 This is a schematic diagram of the elastic protrusion structure; please refer to [link / reference]. Figure 6In this embodiment, the elastic protrusion 3 includes an elastic connecting portion 31 and an elastic extension portion 32 connected to the elastic connecting portion 31. The elastic extension portion 32 protrudes from the elastic connecting portion 31. The elastic connecting portion 31 is connected to the first side wall 22. The elastic extension portion 32 is disposed near the bottom wall 21 and extends toward the second side wall 23. The distance between the elastic extension portion 32 and the second side wall 23 is less than the thickness of the limiting strip 4. The elastic connecting part 31 is connected to the first side wall 22, and the elastic extension part 32 is disposed near the bottom wall 21. When the spring buckle 5 is installed in the spring slot 2 from top to bottom, it squeezes the elastic connecting part 31, so that a space is formed between the elastic connecting part 31 and the limiting strip 4 to accommodate the spring buckle 5. The spring buckle 5 continues to move downward until it is sleeved on the elastic connecting part 31 and the extension part 32. Since the distance between the elastic extension part 32 and the second side wall 23 is less than the thickness of the limiting strip 4, if the spring buckle 5 comes out from the gap between the elastic extension part 32 and the second side wall 23, it will be blocked by the limiting strip 4, thereby limiting the horizontal direction of the spring buckle 5.

[0034] In this embodiment, the elastic extension 32 is arc-shaped; or, the elastic extension 32 is inclined from the elastic connecting portion 31 toward the second sidewall 23. The elastic extension 32 is arranged in an arc or inclined manner to facilitate the spring clip 5 entering the spring slot 2 and pressing the elastic protrusion 3 until it is fitted onto the elastic protrusion 3.

[0035] Please see Figure 6 In this embodiment, the first sidewall 22 is disposed away from the downlight housing 1; the first sidewall 22 has a through-hole 24; one end of the elastic connecting part 31 away from the elastic extension part 32 is fixed to the first sidewall 22, and the elastic extension part 32 is located in the through-hole 24. When the spring buckle 5 is installed in the spring slot 2 from top to bottom, it squeezes the elastic connecting part 31, so that a space is formed between the elastic connecting part 31 and the limiting strip 4 to accommodate the spring buckle 5. When the elastic protrusion 3 is squeezed, the through-hole 24 provides room for the elastic protrusion 3 to move.

[0036] Figure 7 This is a structural diagram of the limit bar. Figure 8 yes Figure 7 For a magnified view, please refer to Figure 6-8 In this embodiment, the width of the top of the limiting strip 4 gradually decreases along the direction close to the opening of the spring slot 2. When the spring clip 5 is installed in the spring slot 2 from top to bottom, the width of the top of the limiting strip 4 gradually decreases along the direction close to the opening of the spring slot 2, which facilitates the spring clip 5 entering the spring slot 2.

[0037] In this embodiment, the width of the middle and bottom of the limiting strip 4 is the same, and the top end of the limiting strip 4 near the middle of the limiting strip 4 has the same width as the middle of the limiting strip 4. The equal width of the middle and bottom of the limiting strip 4, and the equal width of the top end of the limiting strip 4 near the middle of the limiting strip 4, form a straight limiting strip 4, which serves to limit the movement of the spring clip 5.

[0038] In this embodiment, a second gap is formed between the limiting strip 4 and the first sidewall 22 to accommodate the spring latch 5. This second gap facilitates the spring latch 5's entry into the spring slot 2.

[0039] Example 2

[0040] This embodiment provides a downlight. Figure 9 This is a structural diagram of the downlight from another angle. Figure 10 This is a schematic diagram of the spring clip structure. Please refer to it. Figure 2 and Figure 9-10 The downlight includes a spring clip 5 and the spring mounting structure of embodiment 1; the spring clip 5 includes a torsion spring 51, a mounting frame 52 and a spring clip 53, the mounting frame 52 and the spring clip 53 are respectively fixed to both sides of the torsion spring 51; the mounting frame 52 is installed in the spring slot 2 from the opening of the spring slot 2 and sleeved on the elastic protrusion 3, and part of the mounting frame 52 is located in the first gap formed between the elastic protrusion 3 and the bottom wall 21; the spring clip 53 is located outside the spring slot 2.

[0041] In this embodiment of the downlight, the spring clip 5 is securely engaged with the spring slot 2 via the mounting frame 52, and the snap 53 is located outside the spring slot 2, allowing the snap 53 to engage with the wall after being pushed into the pre-drilled hole in the wall. Specifically, the torsion spring 51 and the snap 53 are integrally formed, with both ends of the torsion spring 51 extending downward to form the snap 53; a connecting rod passes through the torsion spring 51, and the mounting frame 52 is fixed to the torsion spring 51 via the connecting rod and extends downward, with the mounting frame 52 and the snap 53 forming a certain angle.

[0042] Please see Figure 2 and Figure 9In this embodiment, the downlight housing 1 includes an inner housing 11 and an outer housing 12. The inner housing 11 is used to accommodate the lamp body, and the outer housing 12 is fitted onto the inner housing 11. The inner housing 11 has a first notch, and the outer housing 12 has a second notch corresponding to the first notch. The first notch and the second notch surround to form a spring slot 2. The portion of the inner housing 11 that forms the first notch serves as a first sidewall 22, and the portion of the outer housing 12 that forms the second notch serves as a second sidewall 23 and a bottom wall 21. The mounting frame 52 enters the spring slot 2 through the opening, sequentially pressing the elastic connecting part 31 and the elastic extension part 32, creating space between the elastic connecting part 31 and the limiting strip 4 to accommodate the mounting frame 52. The mounting frame 52 continues to move downward until its bottom end reaches the first gap between the elastic extension part 32 and the bottom wall 21. The two sides of the mounting frame 52 are located at the two ends of the elastic connecting part 31, so that the mounting frame 52 is fitted onto the elastic protrusion 3. At this time, the elastic connecting part 31 and the elastic extension part 32 are reset and cooperate with the limiting strip 4 to prevent the mounting frame 52 from coming out of the gap between the elastic protrusion 3 and the second side wall 23. The torsion spring 51 is located at the opening of the spring slot 2, and the snap 53 is located outside the spring slot 2. A handle is provided at the end of the snap 53 away from the torsion spring 51.
