Abstract

The utility model discloses a glass product; to be specific, the utility model provides a lamp glass cover; the glass cover is more convenient for installation; the cost is lower and the high-temperature resisting capability is excellenter. The glass cover includes an inter-layer glass and an outer-layer glass; the inner-layer glass is equipped in the outer-layer glass and one end is connected with one end of the outer-layer glass; the inner-layer glass forms a first hollow cavity which can hold the lamp bulb along the axial direction of the glass cover; a secondary hollow cavity is formed between the inner-layer glass and outer-layer glass; the upper end port of the first hollow cavity is equipped with female threads which can be matched with the male threads of the lamp holder shell.

Description

The light fixture cloche

Technical field

The utility model relates to glassware, provides particularly that a kind of installation is more convenient, cost is lower, more resistant to elevated temperatures light fixture cloche.

Background technology

Growing along with China market economy, the style of the critical piece cloche of light fixture emerges in an endless stream, yet the cloche that designs in the prior art, with other parts of light fixture be connected the problem that the ubiquity interconnection technique falls behind.Prior art is to hole on cloche, by handware cloche is connected with shell of lamp base then, and is time-consuming, cost is high, and not attractive in appearance.Handware is easy oxidation damage owing to the high-temperature baking that produced by bulb.In addition, prior art is directly boring on cloche, and difficulty of processing is big, and adopts simple glass production, and heat resistance is not good, bursts when being subjected to high temperature easily.

The utility model content

Main order of the present utility model is to overcome deficiency of the prior art, provides that a kind of installation is more convenient, cost is lower, more resistant to elevated temperatures light fixture cloche.

To achieve these goals, the technical solution adopted in the utility model is:

A kind of light fixture cloche, this cloche comprises inner layer glass and glass outer, wherein, this inner layer glass is positioned at glass outer one end inner and by one end and glass outer and interconnects, this inner layer glass form along the cloche axis direction can ccontaining light fixture bulb first cavity, form second cavity between this inner layer glass and the glass outer, the upper port of this first cavity is provided with the internal thread that can match with the external screw thread on the light fixture shell of lamp base.

The following end closure of this first cavity or be provided with opening.

The outer wall of this inner layer glass is provided with the sandblast layer or is coated with translucent coating, and this glass outer is the transparent body.

Because the upper port of first cavity is provided with internal thread, therefore, can directly cloche be bolted in suitable having on the externally threaded shell of lamp base, not only install simple, convenient, save time, and save the operation of punching together, reduced cost.Simultaneously saving of handware added cloche and is divided into inside and outside two-layerly, and glass outer is transparent, inner layer glass is provided with the sandblast layer or be coated with translucent coating, makes whole light fixture more attractive in appearance.In addition, adopt threaded engagement, save handware, and cloche adopts more resistant to elevated temperatures high-boron-silicon glass pipe to make, the hear resistance of light fixture is improved.

Below in conjunction with drawings and Examples the utility model is further described.

Fig. 1 is a kind of three-dimensional decomposition texture schematic diagram that other parts of the utility model embodiment and light fixture cooperate;

Fig. 2 is the another kind of three-dimensional decomposition texture schematic diagram that other parts of the utility model embodiment and light fixture cooperate;

Fig. 3 is another three-dimensional decomposition texture schematic diagram that other parts of the utility model embodiment and light fixture cooperate.

The specific embodiment

As Fig. 1, Fig. 2, shown in Figure 3, the described light fixture of present embodiment cloche 1, comprise inner layer glass 2 and glass outer 3, wherein, this inner layer glass 2 is positioned at the inside of glass outer 3, and interconnects by an end of one end and glass outer 3, this inner layer glass 3 form along light fixture with cloche 1 axis direction can ccontaining light fixture bulb first cavity 5, form second cavity 6 between this inner layer glass 2 and the glass outer 3, the upper port of this first cavity 5 is provided with internal thread 7.

Comprise bulb 8 and shell of lamp base 9 with the lamp holder that light fixture matches with cloche 1.This lamp holder can be selected GP lamp holder E14 or E27 for use, and its shell of lamp base 9 is provided with external screw thread 10.Above-mentioned internal thread 7 is processed into the model that is complementary with external screw thread 10.

Like this, when this light fixture is installed with cloche 1, can directly light fixture be rotated with on lamp holder with cloche 1 by the external screw thread 10 on internal thread on it 7 and the shell of lamp base 9.With the available technology adopting handware light fixture is connected on the lamp holder with cloche and compares, the utility model light fixture is more convenient with installation, the dismounting of cloche 1.Saved handware, not only saved cost, and avoided influencing drawback attractive in appearance owing to handware is subjected to the high-temperature oxydation corrosion.

The lower end of this first cavity 5 is provided with opening 11, and the heat that bulb is discharged in time distributes by cross-ventilation, avoids lamp holder and light fixture too high with the temperature of cloche 1.

This light fixture adopts high-boron-silicon glass to make with cloche 1, can anti-high temperature more than 300 ℃.Compare with cloche with the light fixture of available technology adopting simple glass, resistance to elevated temperatures is better, is difficult for bursting.In addition, when making this light fixture with cloche 1, can glass outer 3 and inner layer glass 2 makes respectively get well after, by the coal gas oxygen flame, inner layer glass 2 and glass outer 3 sintering are in the same place, manufacture more or less freely.Avoided in the prior art changeing on cloche the problem of hole difficulty at light fixture that glass makes.

In addition, the outer wall of this inner layer glass 2 is provided with the sandblast layer or is coated with translucent coating (not shown), and this glass outer 3 is the transparent body.Like this, the transparent cover of the saving of handware, double glazing adds the setting of sandblast layer, makes light fixture more attractive in appearance on the whole.

The above only is preferred embodiment of the present utility model; when the scope that can not limit the utility model patent application with this; be allly to replace and modify etc. according to the utility model patent claim being equal to of doing, all should still belong within the scope of patent application protection of the present utility model.
