Embodiment
See also Fig. 1 to Fig. 5, digital mirror head unit provided by the utility model mainly includes: a lens mount 1 and can be screwed together in the lens barrel 2 in lens mount 1 endoporus 11; Wherein:
This lens mount 1, its endoporus 11 walls are provided with one a section internal thread 12 and a salient point contact site 13, and the salient point contact site 13 of present embodiment is made as a level and smooth friction hole wall, and certainly, the aperture of this friction hole wall is equal to or greater than the aperture of internal thread 12;
This lens barrel 2, its periphery wall are provided with one section external thread 21, an outer portion 22, and a torsion adjustment part 23 that is positioned at 22 of external thread 21 and outer portion;
This lens barrel 2 rotates and is arranged on the lens mount 1, its external thread 21 that utilizes lens barrel 2 is by behind the salient point contact site 13 of this lens mount 1, and with the internal thread 12 of lens mount 1 with screw thread mutual designation mutually, both pass on motion via mutual guiding function again the external thread 21 of this lens barrel 2 and the internal thread of lens mount 1 12, when the external thread 21 of this lens barrel 2 can utilize the internal thread 12 of lens mount 1 to regulate digital mirror head unit interior location, make the position, summit of torsion adjustment part 23 prop up and be supported in the salient point contact site 13 of lens mount 1, and then be embedded in a salient point contact site 13 of this lens mount 1 inside.
The torsion adjustment part 23 of present embodiment is that three above quantity constitute, but its annular arrangement is in the outside surface of lens barrel 2, but the spacing stationary phase of its annular arrangement is arranged together or according to distance inequality, and this torsion adjustment part 23 also can form along lens barrel 2 outside surface equal angles or non-equal angles distribution setting; Torsion of the present utility model adjustment part 23 presents convex in present embodiment, it also can be cone, cone, hemisphere, prism or it is in conjunction with the outside surface that is arranged at lens barrel 2; This torsion adjustment part 23 and external thread 21 preset distance of being separated by, simultaneously, the maximum outside diameter that its each circular-arc surface constituted is equal to or greater than the aperture of lens mount 1 its salient point contact site 13, therefore, when the internal thread 12 of the external thread 21 of lens barrel 2 and lens mount 1 screwed togather mutually, each 23 circular-arc surface, torsion adjustment part of its torsion adjustment part 23 just can produce with the hole wall of salient point contact site 13 reverse rubbing contact.
As shown in Figure 7, the torsion adjustment part 23 of this lens barrel 2 is to reverse frictional resistance in salient point contact site 13 inner formation of lens mount 1, thereafter, after lens barrel 2 propped up and be supported in the salient point contact site 13 of lens mount 1 with torsion adjustment part 23, then the outer portion 22 of this lens barrel 2 and 14 of lens mount 1 opposing end surfaces then were formed with a gluing space 24.
Digital mirror head unit of the present utility model, further can via the screw thread in lens barrel 2 and the lens mount 1 mutually mutual designation screw in and reverse the friction location, thereafter, can be the adhesive agent 25 of heat-curable glue again in these gluing space 24 inner coatings one, as Fig. 6, shown in Figure 9, to form the gummed driving fit of whole circle; Certainly, as shown in Figure 8, lens barrel 2 of the present utility model and lens mount 1 and known identical can be installed several eyeglasses 3 in advance in inside when actual assembled.
It should be noted that, because the utility model lens mount 1 and lens barrel 2 are when mutual designation screws in and reverses friction and locatees mutually via screw thread, between the two more can be by the frictional resistance that reverses of salient point contact site 13 with 23 generations of torsion adjustment part, this lens mount 1 is combined closely each other with this lens barrel 2, therefore, can effectively overcome and knownly in the combine and assemble process, produce in small, broken bits or small broken end easily because of thread gaps, powder quarrel and can influence the sharpness of photographic picture, cause the problem of influence photography quality, in addition, the utility model utilizes the design of the whole circle of coating adhesive agent 25 in the gluing space 24, this adhesive agent 25 can make lens mount 1 cohere mutually with the surface of contact of lens barrel 2, as rubber, synthetic resin etc., this adhesive agent 25 is except that can further improve lens mount 1 and lens barrel 2 bonding tightness, the more important thing is and to produce sealing effectiveness, to prevent that extraneous dust or moisture from infiltrating lens mount 1 and lens barrel 2 inside via this between cog slit, the result that causes photographing produces problem smudgy or that refraction is damaged, so structure of the present utility model really can increase the sharpness and the quality stability of photography.
