Description
Technical field
The invention belongs to photographic goods technical field, be specifically related to a kind of intermediate plate for filter support.
Background technology
At present, on existing filter support, be equipped with flexible plastic sheet, adjacent plastic sheet uses bolted on filter support, rely on the Surface Contact of plastic sheet single-point and filter eyeglass to produce distortion, form elastic clamping filter, although this kind of structure is simple in structure, but repeatedly extract after can cause filter sheet wearing and tearing, scratch, filter sheet inserts effective usable floor area that can take filter sheet when adjacent plastic sheet forms holding force, causes the inconvenience in work, is therefore necessary to improve.
Summary of the invention
The technical matters that the present invention solves: a kind of intermediate plate for filter support is provided, adopt arc cantilever shell fragment and Compress Spring composition Double-spring structure to carry out clamping square filter sheet, filter sheet does not does not only wear and tear in the time of clamping, and can increase effective usable floor area of eyeglass, and handling are simpler, convenient.
The technical solution used in the present invention: for the intermediate plate of filter support, there is body, described body middle part is shaped with T-shaped limited block, two ends, body side symmetry is shaped with arc cantilever shell fragment, the free end of described arc cantilever shell fragment is stuck in the stopper slot of T-shaped limited block side and with body sidepiece and forms cavity, elastic device is located in cavity and its one end pushes against arc cantilever shell fragment medial surface, its other end pushes against body sidewall pushes against arc cantilever shell fragment and stopper slot sidewall, described body upper surface is also shaped with through hole, both sides, body upper surface are all shaped with reference column, its relevant position, back side is all shaped with the pilot hole suitable with reference column, body lateral surface is shaped with gathering sill I, described arc cantilever shell fragment lateral surface is shaped with gathering sill II.
Wherein, described elastic device is Compress Spring, described arc cantilever shell fragment medial surface is shaped with spring stack I, body sidewall and spring stack I opposite position are shaped with spring stack II, between described spring stack I and spring stack II, leave gap, Compress Spring two ends are set in spring stack I and spring stack II.
Further, described spring stack I and spring stack II are obliquely installed, after described Compress Spring two ends are enclosed within spring stack I and spring stack II and body bottom face be angle setting.
Further, described Compress Spring and body bottom face are 10 ° of-30 ° of angle settings.
Further, described body and arc cantilever shell fragment are integral die moulding.
The present invention compared with prior art laterally clamps filter sheet, stop the phenomenon that filter support and filter sheet in the past use Surface Contact, the filter sheet that do not wear and tear uses surface, increase the effective usable floor area of filter, be more suitable for the use of wide-angle and bugeye lens, and it is more convenient, quick to make filter sheet install and use, accurate positioning.
Brief description of the drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is structure schematic diagram of the present invention;
Fig. 3 is use view of the present invention.
Embodiment
Below in conjunction with accompanying drawing 1-3, a kind of embodiment of the present invention is described.
For the intermediate plate of filter support, there is body 1, described body 1 middle part is shaped with T-shaped limited block 2, and body 1 two ends, side symmetry is shaped with arc cantilever shell fragment 3, and above-mentioned body 1 and arc cantilever shell fragment 3 are integral die moulding.The free end of described arc cantilever shell fragment 3 is stuck in the stopper slot 4 of T-shaped limited block 2 sides and forms cavity 5 with body 1 sidepiece, elastic device is located in cavity 5 and its one end pushes against arc cantilever shell fragment 3 medial surfaces, its other end pushes against body 1 sidewall pushes against arc cantilever shell fragment 3 and stopper slot 4 sidewalls, described body 1 upper surface is also shaped with through hole 6, body 1 both sides, upper surface are all shaped with reference column 7, its relevant position, back side is all shaped with the pilot hole 14 suitable with reference column 7, body 1 lateral surface is shaped with gathering sill I 11, described arc cantilever shell fragment 3 lateral surfaces are shaped with gathering sill II 16.
Above-mentioned elastic device is Compress Spring 8, described arc cantilever shell fragment 3 medial surfaces are shaped with spring stack I 9, body 1 sidewall and spring stack I 9 opposite positions are shaped with spring stack II 10, between described spring stack I 9 and spring stack II 10, leave gap, make arc cantilever shell fragment 3 have certain extension leeway, Compress Spring 8 two ends are set in spring stack I 9 and spring stack II 10.Furtherly, described spring stack I 9 and spring stack II 10 are obliquely installed, after described Compress Spring 8 two ends are enclosed within spring stack I 9 and spring stack II 10 and body 1 bottom face be 10 ° of-30 ° of angle settings, preferably 20 ° of angles, torsional deformation when this structure setting can prevent that Compress Spring 8 from compressing, thus better clamp filter sheet.
When use, first the pilot hole on intermediate plate 14 is inserted on the reference column 7 of adjacent clips, then screw and be integrated with the threaded hole 15 on filter support 12 by the through hole 6 on body 1 with bolt 13, intermediate plate is symmetricly set on filter support 12, on filter support 12, can be provided with multiple intermediate plates, when clamping, filter sheet is inserted from the gathering sill I 11 of body 1 side, in order to reduce the wearing and tearing to filter sheet, the groove depth of gathering sill I 11 is very shallow, only guiding, the gathering sill II 16 of the gathering sill I 11 of filter sheet two ends and body 1 side and arc cantilever shell fragment 3 lateral surfaces is fitted, rely on arc cantilever shell fragment 3 and Compress Spring 8 to uphold acting in conjunction and produce elastic force, clamping filter sheet, filter sheet is clamped.As required, on a filter support 12, can clamp multiple filter sheets.
When the present invention installs, can well adapt to the filter sheet of different manufacturers, also can avoid filter sheet both sides to scratch, increase effective usable floor area of filter sheet simultaneously, when multi-disc is used in combination, realize the convenient, fast installation of filter, and simple in structure, practical.
Above-described embodiment, is preferred embodiment of the present invention, is not used for limiting the scope of the present invention, and the equivalence of being done with content described in the claims in the present invention therefore all changes, within all should being included in the claims in the present invention scope.
