Abstract
The utility model relates to an automatic suspended type anti-explosion lamp with safe structure, comprising a main cavity body and a glass cover which is arranged under the main cavity body and is in threaded connection with the main cavity body through a cover ring. The utility model is characterized in that: a connection structure which is used to connect the main cavity body and the glass cover when the screw thread between the main cavity body and the cover ring of the glass cover is loosed is arranged between the main cavity body and the glass cover; the connection structure comprises a draw ring connected with the cover ring, a hanging board connected with the main cavity body and a draw rod connected with the draw ring and the hanging board. When the screw thread between the main cavity body and the cover ring of the glass cover is loosed, the main cavity body and the cover ring of the glass cover are suspended together through a hanging rod by another connection structure. The automatic suspended structure is realized and waste of operation time and the unsafe factors are avoided.
Description
Technical field
The utility model relates to a kind of explosion-proof lamp, and especially relating to a kind of way of realization is underslung explosion-proof lamp.
Background technology
In the existing explosion-proof industry, the general structure of explosion-proof lamp commonly used is plane or fixing structure, the threaded flame-proof type structure.Wherein, the way of realization that the light fixture of threaded flame-proof type structure is general is: main cavity and cloche are connected by the cover circle that links to each other with the cloche form with screw thread, in the time will installing or change light source or maintenance maintenance, the two must be separated, this just brings danger to a great extent and bothers because generally the setting height(from bottom) of light fixture is all more than 3 meters to the installment work personnel, the staff must pass through some aids, carries out work such as lift, rope climbing etc.Will there be following problem in this:
1. in the replacing process, when main cavity separates in an instant with cloche, the easy landing of cloche.
2. after separating successfully, cloche can not put with having, and cloche cover circle screw thread damages easily, causes the difficulty of going back is installed, and in addition, the damage of screw thread causes explosion-proof unsafe factor easily.
Summary of the invention
The utility model mainly is to solve the existing in prior technology problem, thereby after developing a kind of cloche and main cavity separating, the automatic suspension type safeguard construction explosion-proof lamp that the two still can connect together.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of automatic suspension type safeguard construction explosion-proof lamp, have main cavity and be positioned at main cavity, it is characterized in that: also be provided with the syndeton that after the screw thread between main cavity and the cloche cover circle gets loose, still the two can be suspended on automatically together between main cavity and the cloche below by the cloche that the cover circle is threaded with main cavity; Described syndeton comprises the circle that draws that is connected on the cover circle, is connected the boatswain chair on the main cavity, with the pull bar that draws circle to link to each other with boatswain chair.
The technical solution of the utility model can also be further perfect,
As preferably, on the cover circle, be provided with to place restrictions on and draw the some of circle axially-movable boss, every pair of boss comprises convex platform and lower convex platform, the distance between convex platform and the lower convex platform is slightly larger than draws loop diameter.
As preferably, the height of convex platform is a little more than lower convex platform, and in described lower convex platform, the height of other boss of aspect ratio of one of them boss is lower slightly.
In described lower convex platform, the height of other boss of aspect ratio of one of them boss is lower slightly.
As preferably, the two ends of described pull bar are provided with ring, and the described other end that is connected the boatswain chair on the main cavity is provided with aperture, and the described circle that draws is provided with a little ring, one end of described pull bar links to each other with the aperture on the boatswain chair, and the other end of pull bar links to each other with little ring on drawing circle.
As preferably, described slightly larger in diameter of drawing the diameter of circle than the cover circle.
Therefore, the utility model since between main cavity and the cloche by another set of syndeton, when being threaded between main cavity and cloche cover circle gets loose, another set of syndeton just is suspended on the two together by peg, realize automatic suspended structure, the time waste when so just avoiding operating has also been eliminated unsafe factor.
Description of drawings
Accompanying drawing 1 is a kind of structural upright schematic diagram when suspension status of the present utility model.
The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail:
Automatic suspension type safeguard construction explosion-proof lamp as shown in Figure 1 by main cavity 8, has the cloche 9 of cover circle 4, and main cavity 8 and cloche 9 are threaded by cover circle 4.Be connected with boatswain chair 3 on the main cavity 8, in the radial direction of covering circle 4 diameter is housed and encloses 1 than bigger the drawing of cover circle, draw on the circle 1 and be connected with a little ring, installation is drawn the position of circle 1 to be provided with and is placed restrictions on 4 pairs of boss that draw the circle axially-movable on the cover circle 4, every pair of boss comprises convex platform 6 and lower convex platform 5, the height of convex platform is a little more than lower convex platform, in lower convex platform 5, the height of other lower convex platform 5 of the aspect ratio of one of them lower convex platform 7 is lower slightly, distance between convex platform and the lower convex platform is slightly larger than draws circle 1 diameter, draw circle 1 will cover snare by top four boss 6 and following four boss 5 and 7 usefulness, draw the little ring 11 that encloses on 1 to link to each other with the ring 21 at pull bar 2 two ends with aperture on the boatswain chair 3.
During installation, earlier lower convex platform 7 is entangled, a little firmly will draw circle to draw about 45 degree outward then, on boss 5, screw on again with screw, convex platform 6 is for after split than the high purpose of lower convex platform, and cover circle 4 falls power up, draws circle 1 to be buckled in convex platform 6 and can not drop out with regard to what let nature take its course.Two screws of boatswain chair 3 usefulness are fixed on the main cavity 8, the ring 21 of pull bar 2 by two ends connect draw circle 1 to be connected and fix with boatswain chair 3 light fixtures after, owing to light source damages or other reason demand when safeguarding, unscrew the screw thread between main cavity 8 and the cover circle 4, when main cavity 8 and cloche 9 are thrown off, hooked by pull bar 2 when cloche 9 comes off downwards and form the suspension shape, can not produce the phenomenon on the ground that hangs down because of coming off.
