Abstract
The utility model discloses a molybdenum guide arm for lamps and lanterns, including base pole, intermediate lever and ejector pin, the intermediate lever is installed perpendicularly the intermediate position of base pole, the ejector pin is installed perpendicularly the intermediate position of intermediate lever, just base pole, intermediate lever and ejector pin integrated into one piece set up, the square groove of two symmetries is seted up to the side of ejector pin, and it has the mounting hole just to run through between two square grooves, along the helicla flute has been offered on the outer circumferencial direction of ejector pin. Adopt base pole, intermediate lever and ejector pin three -section structure integrated into one piece to make to be provided with helicla flute and mounting hole on the ejector pin, install through the screw thread on the one hand, on the other hand can be in the mounting hole connecting piece such as driven -in pin axle install, the installation is reliable, makes the installation more convenient with the process of dismantling, through setting three -section structure to, to be convenient for on the one hand dispel the heat when electrically conductive production high temperature, on the other hand makes the electric current of process and voltage more stable.
Description
Technical field
This utility model relates to technical field of lamps, particularly relates to a kind of molybdenum guide rod of conduction on light fixture.
Background technology
Light fixture is when installing and using, it is necessary to using guide rod, current guide rod is generally adopted molybdenum guide rod, is applied on light fixture by molybdenum guide rod, for instance above hernia lamp, can either conduct electricity and be capable of withstanding high temperature.But current molybdenum guide rod is a polished rod, one is conveniently not easy to install, and on the other hand in use, radiating effect needs to be improved further, simultaneously so that electric current and voltage are more stable, it is necessary to molybdenum guide rod is improved.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that a kind of light fixture molybdenum guide rod.
This utility model is to be achieved through the following technical solutions:
A kind of light fixture molybdenum guide rod, including base rod, intermediate bar and push rod, described intermediate bar is vertically mounted on the centre position of described base rod, and described push rod is vertically mounted on the centre position of described intermediate bar and the one-body molded setting of described base rod, intermediate bar and push rod；The side opening of described push rod is provided with two symmetrical square grooves, and runs through between two square grooves and have installing hole, offers helicla flute on the excircle direction of described push rod.
As optimal technical scheme of the present utility model, described base rod away from the curved portions being provided with outwardly convex on the surface of intermediate bar, this curved portions and the one-body molded setting of base rod.
As optimal technical scheme of the present utility model, the diameter of described push rod is minimum, and the diameter of base rod is maximum；The length of described base rod is the shortest, and the length of push rod is the longest.
As optimal technical scheme of the present utility model, described installing hole is circular hole.
As optimal technical scheme of the present utility model, the centrage of described base rod, intermediate bar and push rod is on same straight line.
Compared with prior art, the beneficial effects of the utility model are: 1, this utility model adopts base rod, intermediate bar and push rod three stage structure is one-body molded makes, and on push rod, it is provided with helicla flute and installing hole, installed by screw thread on the one hand, the connectors such as bearing pin can be inserted in installing hole on the other hand to install, install reliable so that the process of installation and removal is more convenient；2, by being arranged to three stage structure, be easy to when conduction produces high temperature on the one hand and dispel the heat, make on the other hand through electric current and voltage more stable, the service life of light fixture increases.
