Description
Technical field
The utility model relates to a kind of lighting, particularly a kind of ceiling type explosion-proof lamp.
Background technology
Explosion-proof lamp refers to the hazardous area existed for imflammable gas and dust, can prevent lamp inner issuable electric arc, spark and high temperature to ignite imflammable gas in surrounding environment and dust, thus reach the light fixture of requirement of explosion proof.Existing ceiling type explosion-proof lamp, as shown in Figure 1, it generally comprises the mounting bracket 101, anti-explosion terminal box 102, anti-explosion movable joint 103, lead collar 104 and the light fixture 105 that connect successively from top to bottom.Not only structure is comparatively complicated for the ceiling type explosion-proof lamp of said structure, need during installation to use together with annexes such as mounting bracket 101, anti-explosion terminal box 102, anti-explosion movable joints 103, the many costs of annex are higher, and power line needs first to be incorporated in anti-explosion terminal box 102, again through anti-explosion movable joint 103, finally just can be incorporated in lead collar 104, thus greatly reduce the installation effectiveness of ceiling type explosion-proof lamp, be unfavorable for very much the installation and maintenance of ceiling type explosion-proof lamp, in addition, in the Assembling Production process of reality, the cloche upper end-face edge of light fixture 105 is generally first be pressed on geosphere by trim ring, and then geosphere is connected on the housing of explosion suppression type explosion-preventing lamp, thus cloche has been arranged on the housing of explosion suppression type explosion-preventing lamp, and before trim ring is arranged on geosphere, first the gap epoxide-resin glue between the upper end-face edge of cloche and geosphere to be filled, and then trim ring is arranged on geosphere thus cloche is pressed on geosphere, but, trim ring is being arranged in the process on geosphere, the epoxide-resin glue of filling easily flows out from the faying face between cloche and trim ring or geosphere, produce the phenomenon of leaking glue, light then affect the outward appearance of light fixture 105, heavy then can product rejection be caused.
Utility model content
The technical problems to be solved in the utility model is, not only structure is simple to provide one, and annex is few, and production cost is low, installation and maintenance is convenient, and the ceiling type explosion-proof lamp that can effectively prevent epoxide-resin glue from flowing out from the faying face between cloche and trim ring or geosphere.
For solving the problems of the technologies described above, the utility model provides and a kind ofly adopts the ceiling type explosion-proof lamp of following structure: comprise lead collar and light fixture, light fixture comprises housing, geosphere, cloche, protective cover and trim ring, lead collar lower end is connected with housing upper end, geosphere is connected with housing lower end, housing be internally connected with lamp holder, lamp holder is connected with bulb, cloche is enclosed within the outside of bulb, the top of cloche is enclosed within geosphere, trim ring is connected to the inside of geosphere and is pressed on the upper surface of cloche, between the upper outside of cloche and geosphere, there is gap, epoxide-resin glue is filled with in gap, protective cover upper end is connected with geosphere lower end, wherein, lead collar top is provided with an explosion-proof chamber communicated with the inner chamber of lead collar, the perisporium of explosion-proof chamber is provided with two through wires holes communicated with explosion-proof chamber, lead collar upper end is provided with mount pad, mount pad is provided with two screw holes passed for screw, gap lower end is provided with a sealing gasket, sealing gasket is pressed between cloche and geosphere, on trim ring, circumference is evenly equipped with some manholes, some manholes all communicate with gap.
After adopting said structure, the utility model has the following advantages: first, because a kind of ceiling type explosion-proof lamp of the utility model is by mounting bracket originally, anti-explosion terminal box and lead collar have been designed to one, and eliminate the anti-explosion movable joint be originally connected between anti-explosion terminal box and lead collar, therefore not only structure is simple for a kind of ceiling type explosion-proof lamp of the utility model, and the quantity of annex also greatly reduces, thus effectively reduce the production cost of a kind of ceiling type explosion-proof lamp of the utility model, in addition, a kind of ceiling type explosion-proof lamp of the utility model when mounted, power line is only needed to introduce from through wires hole in the explosion-proof chamber on lead collar inner chamber top, therefore installation and maintenance is very convenient, secondly, because gap lower end is provided with a sealing gasket, sealing gasket is pressed between cloche and geosphere, on trim ring, circumference is evenly equipped with some manholes, some manholes all communicate with gap, therefore, in the Assembling Production process of reality, after gap is filled with epoxide-resin glue, trim ring is being arranged in the process on geosphere, under the effect of sealing gasket, the epoxide-resin glue of filling can not flow out between cloche and geosphere, unnecessary epoxide-resin glue can enter in the manhole on trim ring, thus there will not be the phenomenon of leaking glue, ensure that product quality.
