Description
Technical field
The utility model relates to a kind of lighting, specifically is a kind of head lamp.
Background technology
Head lamp is a kind of light fixture that illumination was gone up and provided to head that is worn on, fields such as it is widely used in climbing the mountain, camps, exploration, large-scale construction operation, machine maintenance, accident maintenance, rescue and relief work.Because traditional head lamp illumination zone is narrow, irradiated area is little; Therefore present most of head lamp adopts zoom formula head lamp to adjust the range of exposures and the irradiation distance of head lamp, the range of exposures that this zoom formula head lamp is regulated illuminator through the focal length of lens and illuminator in the adjusting lampshade.The structure of this zoom formula head lamp generally comprises support, lamp socket, switch, power supply, fairlead, lampshade, lens and illuminator; Described lamp socket and support are hinged, and illuminator is installed on the lamp socket, and described fairlead is fixedly connected with lamp socket; Described lens are installed in the endoporus of lampshade; Described lampshade and fairlead endoporus matched in clearance, and the sidewall of lampshade is provided with guide finger, and the fairlead sidewall is provided with along its axially extended pilot hole; Described guide finger matched in clearance and is installed with an adjusting knob on the outer face of guide finger in pilot hole.This head lamp promotes adjusting knob through front and back and adjusts the distance of lampshade and illuminator, thereby reaches the purpose of focusing.The focusing type head lamp of this structure in use comes with some shortcomings: such as, when focusing, adopt and promote the distance that adjusting knob is adjusted lampshade and illuminator, promote in the process of adjusting knob; The mobile range of lampshade is big; Not steady, can not accurately focus, operation is inconvenience comparatively; In addition, hard-wired adjusting knob is easy to come off on the outer face of guide finger, thereby influences the adjusting of head lamp focal length, uses comparatively inconvenience.
The utility model content
The technical problem that the utility model will solve is, overcomes the defective of above prior art, provide a kind of focusing convenient, accurately, head lamp stably.
The technical solution of the utility model is; A kind of head lamp with following structure is provided: it comprises support, lamp socket, switch, power supply, fairlead, lampshade, lens and the illuminator that is used to install elastic cord, and described lamp socket and support are hinged, and described fairlead is fixedly connected with lamp socket; Described lampshade and fairlead endoporus matched in clearance; Said lens are installed in the lampshade, and the sidewall of said fairlead is provided with two along its axially extended pilot hole, and the sidewall of said lampshade is provided with two leads; In two pilot holes of said two lead matched in clearance on the fairlead sidewall, and the free end of two leads is arranged on outside the sidewall of fairlead; The adjusting knob that has been rotatably connected on the said fairlead, the inwall of said adjusting knob is provided with one along its axially extended helical guide slot, and the free end matched in clearance of said lead is in helical guide slot.
After adopting above structure; The utility model head lamp compared with prior art has the following advantages: this head lamp rotates adjusting knob with hand when the adjustment focal length; Adjusting knob rotates on fairlead; The lead that helical guide slot on the adjusting knob inwall drives on the lampshade moves along the pilot hole on the fairlead, thereby adjusts the distance of interior lens of lampshade and illuminator, reaches the purpose of focusing; The focusing structure focusing of this head lamp is very convenient, accurate and steady, the deficiency of also having avoided adjusting knob of the prior art to come off simultaneously.
As a kind of improvement, said fairlead bottom is provided with two circular arc stopper slots, and the lower end of said adjusting knob is provided with two limited posts, and described two limited posts are positioned at the circular arc stopper slot.When rotating adjusting knob, circular arc stopper slot end walls is spacing to the limited post of adjusting knob lower end, thereby prevents that adjusting knob rotation amplitude from crossing ambassador's lampshade and coming off, and therefore operates as safe as a house, convenient.
