Description

Technical Field

[0001] The utility model relates to the technical field of lighting, in particular to a recessed downlight which is easy to assemble and disassemble. Background Art

[0002] In the application process of embedded downlights, in addition to the traditional installation method of embedding in the ceiling, there is also an installation method of connecting with a junction box, where such junction boxes are all standard products in the existing market.

[0003] The inventors have observed that traditional recessed downlights using conventional retaining springs typically experience two phenomena during the connection process with the junction box: one is that the lamp is easy to insert into the junction box, but difficult to remove during maintenance, and may even damage the lamp or junction box; the other is that after the lamp is inserted into the junction box, it has poor stability and is prone to falling off.

[0004] The reason is that the conventional retaining springs of existing embedded downlights are usually designed to adapt to ceiling installation. For example, similar to the existing technology "Downlight Installation Structure and Downlight" (patent application number 202321827817.7), this type of downlight needs to be installed through the retaining spring and the lampshade to clamp the ceiling panel to fix the lamp body. Therefore, the supporting part of the retaining spring needs to be close to the lamp body in the design so that when the retaining spring is turned outward at a small angle, it can generate a lasting inward elastic clamping force.

[0005] However, the existing junction box structure is different from the ceiling, and its space is limited. Figure 1 As shown, when this type of existing embedded downlight is matched with the junction box, its retaining spring needs to be turned outward to a state close to the flush state of the tail end of the lamp body so that the tail end of the lamp body can be received into the junction box. At the same time, it is necessary to rely on the inward elastic clamping force of the retaining spring to form supporting friction with the inner wall of the junction box to stabilize the matching position of the lamp body. Therefore, when the retaining spring is turned outward at an excessively large angle for a long time, it will cause damage to itself, thereby affecting the durability of its elastic force, and thus it is impossible to ensure a long-term stable connection between the lamp body and the junction box.

[0006] On the other hand, Figure 2 As shown, for some existing embedded downlights with shorter retaining springs, although the retaining springs can be inserted into the junction box without being turned outward and engage with the inner groove of the opening end of the junction box to stabilize the lamp body, when disassembling, the lamp body can only be pulled outward, which makes disassembly very inconvenient and can easily damage the retaining springs or even the lamp body.

[0007] It can be seen that how to solve the two situations mentioned above is the key to solving the problem of stable matching between embedded downlights and junction boxes. Utility Model Content

[0008] Therefore, the main purpose of the present invention is to provide a recessed downlight that is easy to install and remove, so as to solve the two problems mentioned in the background art and facilitate installation, removal and maintenance between the lamp and the junction box.

[0009] In order to achieve the above-mentioned purpose, according to one aspect of the utility model, a recessed downlight that is easy to load and unload is provided, which is suitable for being assembled with a junction box, comprising: a lamp body, a retaining spring, the retaining spring being arranged on the outer wall of the lamp body, wherein the retaining spring comprises: a torsion spring, a fixing foot, wherein one end of the torsion spring extends a mounting foot to be engaged with the outer wall of the lamp body, and the other end extends a supporting rod to be connected with the fixing foot, and the mounting foot and the supporting rod are normally outwardly open, wherein the fixing foot is provided with a locking tooth that is engaged with the inner groove wall of the opening end of the junction box.

[0010] Preferably, the torsion springs are arranged in pairs, and the mounting legs of the same pair of torsion springs are connected and the abutting rods are spaced apart, so that the fixing legs are spaced apart from each other.

[0011] Preferably, the foot body section of the fixed foot provided with the latching teeth is cylindrical, and the latching teeth are in the shape of arc teeth.

[0012] 1. Preferably, the latch teeth are arranged in multiple sections at intervals along the longitudinal direction of the fixed foot.

[0013] Preferably, the normal outward opening angle between the supporting rod and the mounting foot is less than 90° and greater than or equal to 30°.

[0014] Preferably, the back surface of the front cover of the lamp body is an annular concave surface, so that the open end of the junction box can sink.

[0015] Preferably, the fixing foot is made of any one of rubber, plastic, resin or a combination thereof.

[0016] The embedded downlight that is easy to assemble and disassemble provided by the utility model cleverly designs the retaining spring to be outward-opening, so that after the retaining spring is compressed inwardly, an outward expansion force can be generated, so that the fixing foot can be pressed tightly against the inner groove wall of the opening end of the junction box. At the same time, the locking teeth on the fixing foot and the inner groove wall of the opening end of the junction box form an inverted structure. Therefore, even when the lamp slides down, the locking tooth structure can be firmly clamped with the inner groove wall of the junction box under the support of the outward expansion force of the torsion spring, so that the lamp is not easy to fall off. At the same time, because the inverted position between the locking teeth and the inner groove wall of the junction box is small, it is not easy to get stuck. Therefore, when disassembling, the lamp can be easily pulled out by applying force to pull down the lamp without damaging the lamp or the retaining spring, thereby meeting the requirements of convenient installation and removal of the lamp.

And one or more of the components in the diagram may be necessary or non-essential, and the relative positional relationship between the components in the above diagram can be adjusted according to actual needs.

[0034] In order to solve the two problems mentioned in the background technology and facilitate the installation and maintenance of the lamp, as Figures 3 to 5 As shown, the present invention provides an embedded downlight that is easy to assemble and disassemble, which is suitable for assembly with a junction box 2. It mainly includes: a lamp body 1, a clip 3, wherein Figure 4 As shown, the clamping spring 3 is matched with the connecting portion 11 on the outer wall of the lamp body 1 to be fixed on both sides of the outer wall of the lamp body 1.

[0035] Among them, Figures 4 and 5 As shown, the clamping spring 3 in this example includes: a torsion spring 31 and a fixing foot 32, wherein one end of the torsion spring 31 extends with a mounting foot 311 for mating with the connecting portion 11 of the outer wall of the lamp body 1, and the other end of the torsion spring 31 extends with a holding rod 312 for connecting with the fixing foot 32, wherein after the clamping spring 3 is compressed inwardly, an outward expansion force can be generated so that the fixing foot 32 can be pressed tightly against the inner groove wall 21 of the open end of the junction box 2. In this example, it is preferred that the mounting foot 311 and the holding rod 312 are set to be normally open outward, that is, Figure 5 As shown, by changing the winding direction of the torsion spring 31, an outward opening angle is formed between the supporting rod 312 and the mounting foot 311. In order to ensure the expansion elasticity of the torsion spring 31 and facilitate the assembly with the junction box 2, the outward opening angle θ can be set to be less than 90° and greater than or equal to 30°.

[0036] In order to enhance the stability of the connection between the fixing foot 32 and the junction box 2, Figure 5 As shown, in this example, the fixing legs 32 are provided with latching teeth 321 that engage with the inner groove wall 21 of the opening end of the junction box 2. Therefore, when the lamp is inserted into the junction box 2, the torsion spring 31 expands the fixing legs 32 outward, and the latching teeth 321 on the fixing legs 32 securely engage with the inner groove wall 21 of the opening end of the junction box 2, thereby strengthening the fixture.

[0037] At the same time, in a preferred embodiment, the latch 321 can be arranged in multiple sections longitudinally. Therefore, through the design of the multi-section latch 321, even if the latch 321 fails to be snapped into place at once when the lamp is assembled with the junction box 2, and there is a slight slippage causing the lamp to slide down slightly, the adjacent rear row of latches 321 can be snapped into place again with the support of the outward expansion force of the torsion spring 31, thereby stopping the slide and improving the stability and reliability of the lamp assembly.

[0038] In addition, in order to improve the reliability of the clip 3, in a preferred embodiment, as Figures 3 to 5 As shown, the torsion springs 31 can be arranged in pairs, and the mounting legs 311 of the same pair of torsion springs 31 are connected so as to be matched with the connecting portion 11 of the lamp body 1 in pairs, while the supporting rods 312 are arranged at intervals so that the fixing legs 32 are spaced apart from each other.

[0039] With this arrangement, two pairs of four fixing legs 32 can be formed on both sides of the lamp, so that when mating with the inner groove wall 21 of the opening end of the junction box 2, it can ensure a snap connection in multiple directions to improve the firmness and reliability of the mating.

[0040] On the other hand, since the inner groove wall 21 at the open end of the junction box 2 is annular, in order to increase the friction contact area between the fixed foot 32 and the inner groove wall 21 when they are in contact, improve the friction resistance, and enhance the matching stability, in this example, it is preferred that the foot body section with the latching tooth 321 on the fixed foot 32 is set to be cylindrical, and the latching tooth 321 here is in the shape of an arc tooth.

[0041] Through this arrangement, not only the shape of the fixing foot 32 and the inner groove wall 21 is more adapted, the contact area is increased and the friction resistance is enhanced, but also, with the arc-shaped latch 321, the undercut position between the latch 321 and the inner groove wall 21 of the junction box 2 can be smaller, and it will not be completely locked, thereby facilitating later disassembly.

[0042] In addition, in order to strengthen the friction resistance between the fixing foot 32 and the inner groove wall 21, and at the same time leave material elasticity for the latch 321 to prevent the latch 321 from breaking during disassembly and assembly, in this example, the fixing foot 32 is preferably made of any one of rubber, plastic, resin or a combination of these materials.

[0043] On the other hand, Figures 6 and 7 As shown, in order to hide the opening of the junction box 2 from the side while leaving room for adjustment of the retaining spring 3 and the junction box 2, so that the lamp can be conveniently assembled with the junction box 2, the latch 321 can be snapped into place with the inner groove wall 21 of the junction box 2. In a preferred example, the back side of the front cover 12 of the lamp body 1 can be set to be an annular concave surface so that the opening end of the junction box 2 can sink, thereby leaving space for floating the lamp up and down, and adjusting the latch 321 of the fixing foot 32 to be matched with the inner groove wall 21.

[0044] The following will describe the process of connecting the embedded downlight and the junction box 2 in this example. Figure 6 As shown, when the lamp is inserted into the junction box 2, the fixing leg 32 of the retaining spring 3 will gradually be squeezed by the inner groove wall 21 of the junction box 2, thereby forcing the torsion spring 31 to form an outward expansion elastic force to support the fixing leg 32 and the inner groove wall 21 of the junction box 2. Then, as the lamp goes deeper into the junction box 2 until the opening of the junction box 2 is immersed in the annular concave surface on the back of the front cover 12 of the lamp body 1, if the locking teeth 321 of the fixing leg 32 can be locked into place with the inner groove wall 21 of the junction box 2, the installation is completed. Otherwise, the depth of the lamp is slightly adjusted until the locking teeth 321 are locked into place. The final appearance of the embedded downlight when it is fully assembled with the junction box 2 is as shown in the figure below. Figure 8 shown.

[0045] When the cam 32 is in the unlocked position, the locking teeth 321 are in the unlocked position, and the locking teeth 321 are in the unlocked position, so that the cam 321 is locked and the cam 322 is locked.
