Description

Technical Field

[0001] This utility model relates to the field of lighting technology, and in particular to a downlight retaining spring suitable for junction boxes and its embedded downlight. Background Technology

[0002] In addition to the traditional method of embedding in the ceiling, recessed downlights can also be installed by connecting to a junction box, and these junction boxes are all standard products in the existing market.

[0003] The inventor has observed that traditional recessed downlights using conventional snap rings typically exhibit two problems when connected to junction boxes: one is that while it is relatively easy for the light fixture to snap into the junction box, it is difficult to remove it during maintenance, and this can often damage the light fixture or the junction box; the other is that the light fixture is unstable after being snapped into the junction box and is prone to falling off.

[0004] The reason for this is that the conventional retaining springs of existing recessed downlights are usually designed to be used in ceiling installations. For example, similar to the existing technology "downlight mounting structure and downlight" (patent application number 202321827817.7), such downlights require the retaining spring to cooperate with the lampshade to clamp the ceiling panel to fix the lamp body during installation. Therefore, in the design, the abutting part of the retaining spring needs to be close to the lamp body so that when the retaining spring is turned outward at a small angle, a lasting inward elastic clamping force can be generated.

[0005] However, existing junction box structures differ from those in suspended ceilings, and their space is limited, as shown in the instruction manual. Figure 1 As shown, when this type of existing recessed downlight is connected to the junction box, the retaining spring needs to be turned outward to be almost flush with the tail end of the lamp body so that the tail end of the lamp body can be retracted into the junction box. Therefore, it can only be used with relatively deep junction boxes. At the same time, it also needs to rely on the inward elastic clamping force of the retaining spring to form a supporting friction with the inner wall of the junction box to stabilize the lamp body connection position. Therefore, when the retaining spring is turned outward at an excessive angle for a long time, it will cause damage to itself, affecting its elasticity durability, thus failing to ensure a long-term stable connection between the lamp body and the junction box.

[0006] Therefore, the key to solving the problem of stable connection between recessed downlights and junction boxes lies in addressing the aforementioned issues. Utility Model Content

[0032] In order to facilitate stable maintenance of the connection between the down lamp and the junction box 9, and facilitate the mounting and dismounting of the down lamp, as shown in Figure 2 The utility model provides a down lamp clamp spring 7, it includes: fixed rod 1, first elastic part 2, bracing piece 3, first top joint 4, second elastic part 5, second top joint 6, wherein in the example, the fixed rod 1, first elastic part 2, bracing piece 3, first top joint 4, second elastic part 5, second top joint 6, are twisted into by a spring wire in turn.

[0033] Specifically, as shown in Figure 2 The first elastic part 2 is curved in an arc shape, the fixed rod 1 and the bracing piece 3 are in a straight rod shape, the first elastic part 2 is connected between the fixed rod 1 and the bracing piece 3 to support the bracing piece 3 to be elastically outward opened in an inclined shape relative to the fixed rod 1. The first top joint 4 is arranged at the tail end of the bracing piece 3, the second elastic part 5 is in an arc shape, and the second top joint 6 is elastically connected with the first top joint 4 through the second elastic part 5.

[0034] The first top joint 4 and the second top joint 6 are in a fluctuation shape, and the peak of the second top joint 6 is closer to the normal a of the inner wall vertical plane of the junction box 9 than the peak of the first top joint 4, as shown in the local enlarged view in Figure 2 That is, the two top peaks are not co-linearly arranged, and the peak of the second top joint 6 is more outwardly protruding than the peak of the first top joint 4, thereby forming two independent elastic abutting systems. This not only increases the friction between the down lamp clamp spring 7 and the inner wall of the junction box 9, but also enables the two independent elastic systems to tolerate each other, effectively reducing the risk of lamp falling caused by relaxation of the elastic part.

[0035] Furthermore, in the preferred embodiment, the normal outward opening angle of the supporting rod 3 and the fixed rod 1 can be set to be less than 90° and greater than or equal to 30°, so as to provide sufficient outward expansion resistance of the first top joint 4 and sufficient elastic support for the second elastic member 5 and the second top joint 6 without damaging the elasticity of the first elastic member 2.

[0036] Through the above arrangement, as shown in Figures 5 to 7 when the tubular lamp clamping spring 7 is matched with the lamp body 81, the fixed rod 1 is vertically connected to the clamping spring seat 82 of the lamp body 81, at this time, as the tubular lamp clamping spring 7 is inserted into the junction box 9, as shown in Figure 6 the inner wall of the junction box 9 will preferentially press the supporting rod 3, at this time, the first elastic member 2 will provide elastic feedback, so that the peak top of the first top joint 4 is in contact with the inner wall of the junction box 9 first, forming the first elastic contact, to ensure the basic assembly friction.

[0037] Then, as the tubular lamp clamping spring 7 is further inserted, since the peak top of the second top joint 6 is designed to be higher than that of the first top joint 4, the peak top of the second top joint 6 will also be in contact with the inner wall of the junction box 9 and be pressed, as shown in Figure 7 at this time, the second elastic member 5 will provide elastic feedback under the elastic support of the first elastic member 2 transmitted by the first top joint 4 and the supporting rod 3, so that the peak top of the second top joint 6 is in contact with the inner wall of the junction box 9, thereby forming the second elastic contact, to increase the assembly friction and form a resistance insurance with the first top joint 4, to mutually tolerate errors and effectively reduce the risk of lamp falling caused by relaxation of the elastic member.

The tail ends of the pair of fixed rods 1 extend towards each other and have clamping rods 72. The coaxial clamping rods 72 are arranged at intervals, and the interval between the clamping rods 72 can leave a torsion and elastic allowance, which facilitates the subsequent installation in the clamping spring seat 82 of the embedded down lamp lamp body 81, and the clamping buckle connection or disconnection.
