Below in conjunction with embodiment, and with reference to accompanying drawing, realization, functional characteristics and the advantage of the utility model purpose is described further.
The specific embodiment
As Fig. 1, Fig. 2 and shown in Figure 3, the utility model provides a kind of focusing type torch embodiment.
Described focusing type torch comprises the cylindrical shell 1 of hollow, these cylindrical shell 1 one ends are threaded with bonnet 2, described bonnet 2 is provided with switch 21, the other end of described cylindrical shell 1 is threaded with the pedestal 3 that is provided with electric light source 5, be arranged with movably focusing 4 on the cylindrical shell 1 that is provided with pedestal 3 one ends, this focusing 4 is provided with lens 6, wherein, be provided with limiting section 41 in the described focusing 4, this limiting section 41 cooperates spacing with pedestal 3 one ends along its auxiliary section 31 that forms that extends radially outwardly.
Specifically, described pedestal 3 is the T font along its axial cross section, is provided with electric light source 5 on this pedestal 3, and this electric light source 5 can be selected LED as required for use, but also can be other electroluminescence devices.A side that is provided with electric light source 5 at described pedestal 3 is a minute surface, and this minute surface is provided with convenient at least one pilot hole 32 of installing, and this pilot hole 32 can be made as one or two, and when the quantity of pilot hole 32 was two, it was with pedestal 3 rotating shaft symmetries; The quantity of described pilot hole 32 can also be made as a plurality of, for example three or four etc.Because described pedestal 3 one sides are minute surface, therefore more rays can be reflected away, the luminous flux of scioptics is increased.The one side of described lens 5 is the plane, and it is spherical that another side is, and the light that can better electric light source 5 be sent becomes collimated light beam.
Also be provided with cannelure 11 on the described cylindrical shell 1, be provided with in this cannelure 11 and 4 water proof ring that cooperate (accompanying drawing does not indicate) of focusing, this water proof ring cooperates with focusing 4, can prevent that sealing enters the position of pedestal 3.Described cylindrical shell 1 outside is provided with spacing collar 12 and tread plate (accompanying drawing does not indicate), wherein, described spacing collar 12 is arranged on cylindrical shell 1 and cooperates an end with pedestal 3, the axially parallel of described tread plate and cylindrical shell 1, this tread plate can increase the contact-making surface with the user, prevents landing; Described spacing collar 12 can prevent that focusing 4 displacement are excessive.
