Summary of the invention
The utility model is for traditional teleconverter and extension ring function singleness, the defect extending focal length or change at a distance of a function can only be realized, the teleconverter that a kind of increment/microspur is two-in-one is proposed, realized the simple and convenient dismounting of extension ring and mirror group by the special construction of trim ring, realize the shooting effect of increment or microspur; And mirror group can be fixed in extension ring and do not shake, ensure shooting effect.
In order to achieve the above object, the utility model adopts and proposes a kind of trim ring, this trim ring inner ring is provided with the guide slide installing fixed bar, the entrance of this guide slide is positioned at trim ring upper surface, chute surface is extended to form to trim ring inside from entrance, chute surface end is provided with draw-in groove, and during installation, mirror group fixed bar slides in draw-in groove fixing by entrance by chute surface;
Described trim ring edge is provided with contact notch part, and trim ring upper surface is provided with at least two grooves, and bottom portion of groove is provided with screw hole, the bore of this groove is slightly larger than the diameter of screw cap, be provided with elastic body in groove, elastomeric upper end is resisted against bottom screw cap, and lower end abutment is at bottom portion of groove.
The utility model proposes a kind of teleconverter being provided with above-mentioned trim ring in addition, comprising: mirror group, and its sidewall is provided with at least two fixed bars; Extension ring, top end face has threaded hole, and described trim ring is fixed by screws on extension ring top end face.When installing mirror group, mirror group fixed bar slides in draw-in groove fixing by entrance by chute surface.
As preferably, guide slide is diametrically outward extending L-type slideway.
As preferably, described mirror group is provided with two symmetrical fixed bars.
As preferably, described trim ring is evenly provided with four cylinder shape grooves.
As preferably, described elastic body is spring, is sleeved on described screw.
As preferably, trim ring material is metal, can be stainless steel or aluminium alloy.
As preferably, described guide slide entrance is U-shaped.
Compared with prior art, advantage of the present utility model and good effect are: teleconverter provided by the utility model is not only with increment function, pull down mirror group just to use as extension ring, a kind of equipment two kinds of functions, to be not only cost-savingly also convenient for carrying; By the special construction of trim ring, coordinate elastic body, achieve the simple and quick dismounting of mirror group, and compressed by trim ring when mirror group is installed in extension ring, can not shake, thus ensure shooting effect.

Embodiment
In order to better understand the utility model, illustrate below in conjunction with drawings and Examples.
Embodiment: as Figure 1-3, teleconverter described in the utility model comprises mirror group 1, extension ring 2 and trim ring 3.Mirror group 1 sidewall is provided with two fixed bars 11, extension ring 2 top end face has the threaded hole 21 for fixing trim ring 2,
Fig. 4, Fig. 5 illustrate the structure of the utility model trim ring, as shown in Figure 4, Figure 5, this trim ring 3 inner ring is provided with the guide slide 31 installing fixed bar 11, the entrance 311 of this guide slide is positioned at trim ring upper surface, chute surface 312 is extended to form to trim ring inside from entrance 311, chute surface 312 end is provided with draw-in groove 313, and draw-in groove 313 upper surface is a little more than chute surface 312.Trim ring 3 edge is provided with contact notch part 32, trim ring 3 upper surface is provided with at least two grooves 33, bottom portion of groove is provided with screw hole 34, the bore of this groove 33 is slightly larger than the diameter of screw cap, elastic body 4 is installed in groove 33, the upper end of elastic body 4 is resisted against bottom screw cap, and lower end abutment is at bottom portion of groove.As shown in Figure 2, screw 5, through the groove 33 on trim ring 3 and the elastic body 4 in groove, by being screwed in the screw hole 21 of extension ring 2 after screw hole 34, is fixed on extension ring 2.
As stereographic map when Fig. 3 illustrates that mirror group is installed on extension ring, during installation, fixed bar 11 is put in trim ring 3 guide slide entrance 311, rotate along chute surface 312 after pressing to bottom, the spatial altitude that now chute surface 312 and extension ring 2 upper surface are formed is less than the height of fixed bar 11, trim ring 3 moves up under the effect of fixed bar 11, the pressure of elastic body 4 pressure ring groove 33 bottom surface and screw cap and shrinking, because the bore of groove 33 is greater than screw cap, screw cap is absorbed in groove 33.Be rotated further in fixed bar 11 to draw-in groove 313, elastic body 4 gives trim ring groove 33 end prone pressure, and trim ring 3 part moves down and is fixed bar 11, and under the pressure of trim ring 3 and the backstop of draw-in groove 33, fixed bar 11 position is fixed.Now, this teleconverter is connected to the effect that can realize extending focal length between camera body and camera lens, under mirror group is tightly fastened on trim ring, can not be moved during shooting, thus ensure shooting effect.When needing microshot, only need backwards rotation mirror group, taken off.Teleconverter described in the utility model achieves microspur/increment two kinds of functions, and convenient to disassembly.
Improve as one of the present utility model, as shown in Figure 7, guide slide 31 is set to diametrically outward extending L-type slideway, and guide slide entrance 311 is U-shaped, and because trim ring thickness is less, this shape is easy to processing.
In order to better fixed mirror group, mirror group 1 is provided with two symmetrical fixed bars 11, trim ring 3 is evenly provided with four cylinder shape grooves 33.
Described elastic body 4 can be spring, is sleeved on described screw 5; Also can be elastic caoutchouc, be filled in trim ring groove 33.
Trim ring 3 material is metal, and can be stainless steel or aluminium alloy, the trim ring intensity of metal material be good, long service life.
The above; it is only preferred embodiment of the present utility model; it is not restriction the utility model being made to other form; the Equivalent embodiments that any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as equivalent variations is applied to other field; but everyly do not depart from technical solutions of the utility model content; according to any simple modification, equivalent variations and remodeling that technical spirit of the present utility model is done above embodiment, still belong to the protection domain of technical solutions of the utility model.
