Abstract
A double-helix-type upper cover used for an energy-saving lamp relates to the technical field of lighting lamps. The double-helix-type upper cover includes a round upper cover body. The edge of the upper cover body protrudes upward, so that a cover edge is formed. The lower end face of the upper cover body is open. The outer wall of the cover edge of the upper cover body is provided with threads. Two round mounting holes are arranged in positions adjacent to two sides of the upper end face of the upper cover body symmetrically. Semicircular blocking edges are arranged at positions of the back face, on the outer peripheries of the mounting holes, of the upper end face. The blocking edges protrude upward. Two ends of each blocking edge are connected to the inner wall of the cover edge in an overlapped manner. Fastening clamps are arranged on the sides of the mounting holes adjacent to the blocking edges. The double-helix-type upper cover used for the energy-saving lamp is simple in structure, reasonable in design and convenient in installation. By using the double-helix-type upper cover, a lamp tube can be fixed well and can be prevented from falling off and service lifetime of the energy-saving lamp can be prolonged. The double-helix-type upper cover can create very good economic benefit.
Description
Technical field
The utility model relates to illuminating lamp technical field, is specifically related to a kind of double helical form electricity-saving lamp upper cover.
Background technology
Electricity-saving lamp, is called again Electricity-saving lamp bulb, electronic bulbs, compact fluorescent lamp and Integral fluorescent lamp, refers to fluorescent lamp and ballast (stabilizer) are combined into an overall lighting apparatus.Within 2008, country starts " green illumination " engineering, and urban and rural residents and enterprise are used acceptance of the bid industry energy conservation lamp to enjoy a certain proportion of subsidy, and the dissemination of electricity-saving lamp is great.
Show in November, 2011 according to " 2013-2017 China's electricity-saving lamp manufacturing production and marketing demand and investment forecasting analysis report " data, China issues " incandescent lamp is eliminated route ", and route is pointed out: be the transitional period on September 30,1 day to 2012 November in 2011; Play nonimportation on October 1st, 2012 and sell 100 watts and above ordinary lighting incandescent lamp; Play nonimportation on October 1st, 2014 and sell 60 watts and above ordinary lighting incandescent lamp; Be the mid-stage assessment phase on September 30,1 day to 2016 October in 2015; Play nonimportation on October 1st, 2016 and sell 15 watts and above ordinary lighting incandescent lamp; Or adjust depending on mid-stage assessment result.
Incandescent lamp is eliminated, and the market space staying is that electricity-saving lamp has brought huge development potentiality.The coming years, the output of incandescent lamp and demand will reduce gradually, and electricity-saving lamp will be played protagonist.Facing to good opportunity to develop, electricity-saving lamp is also faced with other puzzlement, all needs to improve especially, to ensure safety, high efficiency operating state for traditional production equipment.Traditional light cover is not good for the fixed effect of light cover, easily comes off, and the generation causing the accident.
Utility model content
Technical problem to be solved in the utility model is to improve a kind of double helical form electricity-saving lamp upper cover simple in structure, easy for installation.
Technical problem to be solved in the utility model realizes by the following technical solutions:
A kind of double helical form electricity-saving lamp upper cover, comprise a circular upper cover body, described upper cover body edge raises up to form and covers limit, the lower surface of described upper cover body is opened wide, on the outer wall of described upper cover body cap limit, be provided with screw thread, on described upper cover body upper surface, be arranged with two circular mounting holes near both sides, the back side of described upper surface is positioned at installing hole and is arranged with semicircle rib outward, described rib raises up, the two ends of this rib are overlapped on to be covered on the inwall of limit, be provided with fastener in described mounting hole site in rib one side, this fastener forms fixing fluorescent tube together with rib, prevent fluorescent tube displacement or come off.
The centre, upper surface of described upper cover body is provided with louvre, and this louvre is flaabellum shape.
Described fastener is " 7 " character form structure, is an elastic plastic member, has certain elasticity, prevents fluorescent tube to damage.
