Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of down lamp, especially a mounting structure of down lamp face ring. BACKGROUND

[0002] In the production and assembly process of the down lamp, the connection stability, assembly convenience and cost control of the face ring and the lamp shell are the core consideration factors. In the prior art, the connection mode of the down lamp face ring and the lamp shell mainly adopts buckle type clamping or direct fastening of multiple screws, but both of these two mainstream modes have significant defects and are difficult to balance practicability and economy.

[0003] Among them, although the buckle type connection has the advantage of fast assembly speed, the structural strength of the buckle is limited, and the buckle is prone to fatigue loss due to the influence of environmental temperature changes, daily slight vibration and other factors during long-term use of the down lamp, thereby causing loosening and falling off. This not only causes the face ring to deviate and misalign, directly affecting the lighting effect of the down lamp, but also may cause safety hazards due to the falling off of the face ring.

[0004] The connection mode of direct fastening of multiple screws can improve the connection stability to a certain extent, but the operation is complicated and the cost is high. During installation, the operator needs to manually position and continuously fix the lamp shell and the face ring, and then lock the screws one by one, which significantly increases the assembly time and labor intensity. In addition, the spring clip assembly of the down lamp also needs to be fixed to the lamp shell by screws, which increases the number of screws required during the entire assembly process, increases the material procurement cost, further increases the assembly steps, and reduces the production efficiency. SUMMARY

[0005] The utility model aims at solving one of the problems in the prior art to a certain extent, and provides a down lamp face ring mounting structure which is simple in structure, convenient to install and disassemble, and low in production cost.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical scheme:

[0007] A mounting structure of a down lamp face ring, comprising a lamp shell and a face ring, wherein a circular baffle is arranged on the face ring, the lower end of the lamp shell is arranged in the circular baffle, mounting bosses are symmetrically arranged on the outer side wall of the lamp shell, spring clip assemblies are arranged on the two mounting bosses, a card slot is arranged on the outer side of the mounting boss, a reverse L-shaped hook which can be clamped in the card slot is integrally formed on the circular baffle, and the reverse L-shaped hook and the spring clip assembly are threadedly connected with the mounting boss through a first screw.

[0008] In some embodiments, a slot is arranged at the upper end of the mounting boss, the spring clip assembly comprises a metal sheet inserted into the slot and a spring clip arranged on the metal sheet, and a threaded hole for cooperating with the first screw is arranged on the metal sheet.

[0009] In some embodiments, the inverted L-shaped hook comprises a connecting piece arranged at the upper end of the circular ring baffle and a clasp arranged at the upper end of the connecting piece, the clasp is arranged in the clamping slot, and a through hole for cooperating with the first screw is arranged on the connecting piece.

[0010] In some embodiments, a guide slot for cooperating with the mounting boss is arranged on the circular ring baffle, and the mounting boss is arranged in the guide slot.

[0011] In some embodiments, a limiting convex ring is arranged on the inner side of the lower end of the circular ring baffle, and the lower end of the lamp shell abuts against the limiting convex ring.

[0012] In some embodiments, a spring washer is arranged between the head of the first screw and the outer surface of the inverted L-shaped hook.

[0013] In some embodiments, an extension plate is arranged on the outer side wall of the lamp shell between the two mounting bosses, a screw column corresponding to the extension plate is arranged on the circular ring baffle, and a second screw is arranged on the extension plate and threadedly cooperates with the screw column.

[0014] In some embodiments, a rubber sleeve is sleeved on the end of the spring clip away from the metal sheet.

[0015] Compared with the prior art, the utility model has the beneficial effects that:

[0016] 1. When the face ring is installed, the inverted L-shaped hook integrally formed on the circular ring baffle of the face ring is first precisely clamped and cooperated with the clamping slot on the mounting boss of the outer side wall of the lamp shell, so that the preset positioning and temporary fixing of the face ring and the lamp shell are quickly realized; the preset fixing structure can replace manual holding positioning, and subsequent assembly operation can be completed, so that the installation process is greatly simplified, and the assembly efficiency is effectively improved.

[0017] 2. The first screw can be used to simultaneously realize the synchronous fixing of the lamp shell, the face ring and the spring clip assembly, and multiple groups of screws do not need to be arranged for the connection of the face ring and the fixing of the spring clip assembly; compared with the existing multiple screw fastening mode, the number of screws used is significantly reduced, not only the material cost of the screws is reduced, but also the process of locking the screws is reduced, the production efficiency is further improved, and the labor intensity is reduced.

[0018] 3. The L-shaped hook and the slot engage to form a preliminary mechanical limit. Combined with the tightening effect of the first screw, the face ring and the lamp housing form a double fixing structure, which greatly improves the connection stability. Even if the face ring is affected by temperature changes, slight vibrations and other factors during long-term use, it can effectively prevent the face ring from loosening, shifting or falling off, ensuring the stability of the downlight's lighting effect and the neat and beautiful appearance, while reducing the safety hazards caused by the detachment of parts.
