Abstract

The utility model discloses a ceiling lamp, comprising a lamp cover, an illuminant installed in the lamp cover, and a connection box connected with the lamp cover. At least two screwed mechanisms for pressing are installed on the lamp cover, and the screwed mechanism for pressing is composed of a support bracket, a screw and a screw pressing block; the screw pressing block radically extends out of the screw and is matched with the screw in a screwing way; the screw pressing block can follow the turning screw to move up and down. The conformation of the utility model, making use of the screwing and clamping way of installation, has the light fitting embedded firmly and reliably on the ceiling, and has the advantages of simple and convenient assembly and disassembly, and high safety.

Description

A kind of ceiling ceiling lamp

Technical field

The utility model relates to the field of lighting, the particularly assembly fitting structure on ceiling.

Background technology

The light fixture of tradition assembly on ceiling, be embedded on the installing hole of ceiling in order to allow light fixture bow, generally paired shell fragment or torsion spring are installed on lamp bracket or lamp housing, utilize the elastic force of shell fragment or torsion spring to clamp the ceiling on installing hole limit, light fixture is positioned on the ceiling.But such assembly mode is difficult to meet nation's security standards such as European Union, the U.S., since light fixture only with shell fragment, torsion spring support on ceiling, light fixture is movable with respect to the ceiling installing hole, getting loose arranged at any time, the danger under weighing down, therefore must the mounting structure of traditional smallpox downlight be improved.

The utility model content

The purpose of this utility model is the weak point that overcomes traditional support formula structure, and it is firm, safe and reliable to propose a kind of assembly, simple load and unload again ceiling ceiling lamp.

The purpose of this utility model is achieved by the following technical solution: a kind of ceiling ceiling lamp, include lampshade, be loaded on the lighting source in the lampshade, the terminal box that is connected with lampshade, two spiral hold-down mechanisms are housed on the lampshade at least, the spiral hold-down mechanism is made up of support, screw, spiral briquetting, the spiral briquetting extends radially out outside the screw, and cooperate with the screw spiral, and can move up and down with the rotation of screw.Further, for preventing that the spiral briquetting from developing the inconvenient assembly of lampshade when rotating with screw, the both sides, front and back of screw are respectively equipped with the front apron and the backboard of restriction spiral briquetting pendulum angle when rotating with screw, make the spiral briquetting only can open, fold swing in 0-90 degree scope.For ease of installing, regulating, screw vertically is interspersed on the support, its cap end down, tail end is up and self-locking nut is housed.And the spiral briquetting is the sheet of downward bending.

Such design makes the assembly between light fixture and the ceiling installing hole mechanically be locked by the spiral briquetting, and light fixture and ceiling are no longer loosening, and the light fixture assembly firmly, reliably.When unloading light fixture, but the reverse rotation screw move on the spiral briquetting, remove clamping, and the spiral briquetting is flapped toward front apron to ceiling, light fixture is taken out from installing hole easily, install and remove simple and convenient.

Description of drawings

Fig. 1 is a schematic perspective view of the present utility model;

Fig. 2 is the schematic diagram of the utility model installment state;

Fig. 3 is the schematic diagram of spiral hold-down mechanism.

The specific embodiment

Referring to Fig. 1-Fig. 3, the light fixture of present embodiment mainly is made of lampshade 1, terminal box 2, light cover 3, spiral hold-down mechanism 4 and lighting source.It focuses on spiral hold-down mechanism 4, it is welded in lampshade 1 outer wall both sides with the form of two groups of symmetries, and constitute by support 41, screw 42, spiral briquetting 43, self-locking nut 44, screw 42 vertically is interspersed on the support 41, the cap end of screw 42 down, tail end up, and self-locking nut 44 is loaded on tail end, thereby screw 42 can freely be rotated on support 41 and do not get loose, and the position of corresponding screw 42 cap ends has adjustment hole 31 on the light cover 3, and screwdriver can pass adjustment hole 31 rotation screws 42.Spiral briquetting 43 is loaded on and forms the spiral cooperation on the screw 42, support 41 is provided with front apron 46 in the front side of screw 42, rear side at screw 42 is provided with backboard 47, front and rear baffle 46,47 position just can be limited spiral briquetting 43 and be swung in the angular range of 0-90 degree, like this, when using screwdriver to be rotated in the forward screw 42, spiral briquetting 43 is rocked to backboard 47 places, be in 90 degree deployed position (as shown in Figure 2), be subjected to stopping of backboard 47, spiral briquetting 43 can only constantly move down as straight line with the rotation of screw 42, compress the ceiling on installing hole limit until the lower end of its bending-like, light fixture is clamped and fixed on the ceiling; When reverse rotation screw 42, spiral briquetting 43 is rocked to front apron 46 places, can only be with the rotation of screw 42 moved on constantly by the restriction of front apron 46, on spiral briquetting 43, move to the wedge place 45 of front apron 46, spiral briquetting 43 can be rocked to 0 degree stowed position (as shown in Figure 1), releasing is to the constraint of ceiling, and light fixture can unload from the ceiling installing hole.

Certainly; here only enumerated a kind of preferred implementation; in fact; this spiral hold-down mechanism can be widely used in each alastrim ceiling lamp; and be not limited to concrete form, the structure of light fixture; and the concrete member of spiral hold-down mechanism, form, quantity also can be done multiplely to be equal to, variation roughly the same, and they all should belong to the protection domain of this patent, repeat no more here.

Claims

1, a kind of ceiling ceiling lamp, include lampshade, be loaded on the lighting source in the lampshade, the terminal box that is connected with lampshade, it is characterized in that: two spiral hold-down mechanisms are housed on the lampshade at least, the spiral hold-down mechanism is made up of support, screw, spiral briquetting, the spiral briquetting extends radially out outside the screw, and cooperate with the screw spiral, and can move up and down with the rotation of screw.

2, ceiling lamp according to claim 1, the both sides, front and back that it is characterized in that screw are respectively equipped with the front apron and the backboard of restriction spiral briquetting pendulum angle when rotating with screw.
