Abstract
The utility model relates to a film coating clamp for optical filters, which is used in the film coating procedure in the optical filter production process. The clamp comprises an annular clamp body, wherein a supporting region is formed on the inner periphery of the clamp body and comprises an arc region and a straight line region; the two ends of the straight line region are respectively connected with the two ends of the arc region; and two angle regions are formed at the joints of the arc region and the straight line region. The clamp is characterized in that supporting blocks are fixed on the supporting region. The clamp has reasonable structural design, reduces the contact areas with the optical filters and can reduce the fracture rates of the optical filters.
Description
Technical field
The utility model relates to a kind of optical filter coating anchor clamps, is used in the filming process of spectral filter production process.
Background technology
Need in the spectral filter production process spectral filter is carried out coating film treatment, process is that spectral filter is put in the coating clamp, again anchor clamps is put into umbrella stand, at last umbrella stand is put into the coating equipment plated film.Such as Fig. 1～shown in Figure 3, the coating clamp of prior art comprises the clamp body 1 ' of annular, and the inner peripheral of clamp body 1 ' forms Support 2 ', the Support comprises two angular regions 3 ', spectral filter is placed on the Support 2 ', contacts with whole Support 2 ', and two angles on the spectral filter then are positioned at angular region 3 '.Spectral filter can expanded by heating in coating process, and contacted many to spectral filter of the coating clamp of prior art, thereby spectral filter is broken because of expansion.
The utility model content
Technical problem to be solved in the utility model is to overcome deficiency of the prior art and a kind of optical filter coating anchor clamps are provided, and reasonable in design can reduce the rupture rate of spectral filter.
The technical scheme in the invention for solving the above technical problem is: a kind of optical filter coating anchor clamps, the clamp body that comprises annular, the inner peripheral of clamp body forms the Support, the Support comprises arcuate segments and linearity sector, the two ends of linearity sector link to each other with the two ends of arcuate segments respectively, connecting place in arcuate segments and linearity sector forms two angular regions, it is characterized in that: be fixed with back-up block in described Support.
Back-up block described in the utility model is five.
The utility model has groove in described angular region.
The utility model compared with prior art has following advantage and effect: reasonable in design, the utility model have reduced the contact area with spectral filter, can reduce the rupture rate of spectral filter.

Fig. 1 is the structural representation of spectral filter to be coated.
Fig. 2 is the structural representation of the coating clamp of prior art.
Fig. 3 is the sectional structure synoptic diagram of the A-A of Fig. 2.
Fig. 4 is the structural representation of the utility model embodiment.
Fig. 5 is the structure for amplifying synoptic diagram of B part among Fig. 4.
Fig. 6 is near the structural representation the utility model embodiment angular region.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and by embodiment.
Referring to Fig. 3～Fig. 6, Fig. 1, the utility model embodiment comprises the clamp body 1 of annular, and the inner peripheral of clamp body 1 forms Support 2.Support 2 comprises arcuate segments 21 and linearity sector 22, and the two ends of linearity sector 22 link to each other with the two ends of arcuate segments 21 respectively, and the connecting place in arcuate segments 21 and linearity sector 22 forms two angular regions 3 thus.
2 are fixed with five back-up blocks 4 in the Support, and 3 have groove 5 in the angular region.
During use, spectral filter is placed on five back-up blocks 4, does not contact with whole Support 2, has reduced the contact area with spectral filter, thereby reduces the swelling fracture rate of spectral filter.Two angles on the spectral filter then are positioned at angular region 3, and groove 5 has been given the expansion leeway, two angles on the spectral filter, and when the spectral filter expanded by heating, two angles on the spectral filter can be to groove 5 interior extensions, thereby reduce the rupture rate that two angles of spectral filter cause because of expanding compress.
