Abstract

The utility model discloses an antifogging down lamp decorative ring, which comprises a fixing ring connected fixedly with a down lamp bracket or a shell and embedded with an outer ring of antifogging glass piece, and is characterized in that: the inner wall of the outer ring is provided with two or more latch fastener shrapnels; latch fastener holes corresponding with the latch fastener shrapnels are provided on the ring surface of the fixing ring; the outer ring is covered on the fixing ring and is fixed by the latch fastener shrapnels and the latch fastener holes. With the structure, the antifogging glass piece is safe, firm and reliable in assembly and use, and simple and convenient in assembly and disassembly, thus having wide application in supporting and embedding use with varies spot lamps and down lamps.

Description

A kind of anti-mist barrel lamp rosette

Technical field

The utility model relates to the field of light fixture member, particularly with the rosette of antifog glass.

Background technology

Traditional anti-mist barrel lamp, influence light source in the Down lamp for preventing that steam, dust etc. from entering, be provided with the transparent glass sheet in light source the place ahead, its assembly structure be with sheet glass as interior circle, be connected with the internal diameter of rosette, though can be embedded in the rosette antifog glass is on chip like this, but can only relative fixed between sheet glass and the rosette, as easy as rolling off a log anti-pine, come off, see very insecurely from use angle, have potential safety hazard; On the other hand, the mounting or dismounting of sheet glass extremely bother, and relate to the Down lamp internal structure during mounting or dismounting, involve a plurality of members, and sheet glass is connected with rosette as interior circle, and both are close to same horizontal plane and install, and are difficult to put forth effort the dismounting difficulty during dismounting.

The utility model content

The purpose of this utility model is the structure that changes traditional decoration ring and sheet glass, proposes a kind of easy, firm and reliable connection, anti-mist barrel lamp rosette simple in structure installed and removed.

The purpose of this utility model is achieved through the following technical solutions: a kind of anti-mist barrel lamp rosette, include the retainer ring that is connected with Down lamp support or housing, be inlaid with the outer shroud of antifog glass sheet, the inwall of outer shroud is provided with two or more snap close shell fragments, then be provided with the bonnet lock hole corresponding with the snap close shell fragment on the anchor ring of retainer ring, outer shroud covers on the retainer ring and is connected by snap close shell fragment and bonnet lock hole spinner.Further, the snap close shell fragment is tab shape, the tongue piece undulate that cooperates with bonnet lock hole.

Such design has tangible advantage:

1, locking is firm behind snap close shell fragment on the outer shroud and the bonnet lock hole spinner on the retainer ring, and outer shroud can be anti-loose, the danger that sheet glass does not come off;

2, mounting or dismounting are all carried out on the retainer ring surface, can not involve the Down lamp internal structure, and mounting or dismounting are very convenient, easy;

3, delicate structure is succinct, and production cost is low;

4, safe in utilization, reliable.

Fig. 2 is a three-dimensional assembling schematic diagram of the present utility model;

Fig. 3 is the schematic diagram that the utility model assembly becomes Down lamp.

The specific embodiment

Referring to Fig. 1-Fig. 3, the rosette of present embodiment mainly is made of retainer ring 1 and movable outer shroud 2.Retainer ring 1 central authorities have installing hole 11, so that with the corresponding interlocking of reflection shield of Down lamp and light source is installed, have three bonnet lock holes 12 on the ring body of retainer ring 1; The central authorities of movable outer shroud 2 are inlaid with antifog glass sheet 3, the installing hole 11 corresponding couplings of the diameter of sheet glass 3 and retainer ring 1, solid welding has the snap close shell fragment 21 of three tab shapes on the inner wall of ring body of outer shroud 2, and the distributing position of snap close shell fragment 21 is just in time corresponding with bonnet lock hole 12.The internal diameter of outer shroud 2 is a bit larger tham the external diameter of retainer ring 1, outer shroud 2 enclosures are on retainer ring 1, be adjacent to and be rotated in the forward, the waveform tongue piece 22 of snap close shell fragment 21 is just through the ring body snapping of bonnet lock hole 12 and retainer ring 1 and compress, thereby outer shroud 2 is locked on the retainer ring 1, sheet glass 3 is installed on the rosette.In the time of need unloading outer shroud 2, only need reverse rotation outer shroud 2, make waveform tongue piece 22 withdraw from retainer ring 1 bonnet lock hole 12 and get final product.

Except that Down lamp shown in Figure 3, the utility model also extensively assembly on various forms of anti-mist barrel lamps, shot-light, no longer describe in detail here, and other and retainer ring, outer shroud, snap close shell fragment, bonnet lock hole are equal to, structure roughly the same, all belong to the protection category of this patent.

Claims

1, a kind of anti-mist barrel lamp rosette, include the retainer ring that is connected with Down lamp support or housing, be inlaid with the outer shroud of antifog glass sheet, it is characterized in that: the inwall of outer shroud is provided with two or more snap close shell fragments, then be provided with the bonnet lock hole corresponding with the snap close shell fragment on the anchor ring of retainer ring, outer shroud covers on the retainer ring and is connected by snap close shell fragment and bonnet lock hole spinner.

2, rosette according to claim 1 is characterized in that the snap close shell fragment is tab shape, the tongue piece undulate that cooperates with lockhole.
