Embodiment
The jewel substrate optical filter that rectangle optical filter 4 described in present embodiment is 25.0*1.5*0.5mm.
As shown in Figure 9, a kind of buckle-type erecting device for rectangle optical filter that this patent proposes, comprises filter holder 1, gland 2 and a pair of dome latch 3.
As shown in Figure 1, filter holder 1 adopts the metal cold processing technology of stainless steel material to process, and base thickness is 0.3mm.Rectangle optical filter 4 can be placed on enclosing in frame 1-1 of filter holder 1, the thick 0.3mm of surrounding frame wall, enclose frame in enclose size and rectangle optical filter is in the same size, be 25.0*1.5mm, and the plus tolerance of getting 0.05mm; Filter holder 1 has rectangle light hole 1-3, and size is determined according to the clear aperture of optical system requirement; Enclosing frame one end has a pair of circular hole 1-2, is used for installing dome latch 3, and Circularhole diameter is 0.5mm, gets the plus tolerance of 0.05mm; There is pair of L type draw-in groove 1-4 one end different with circular hole 1-2, and draw-in groove position and size should ensure that gland 2 can freely fall at releasing orientation B, and at stationary state A, fixture block 2-3 can be inserted in draw-in groove 1-4; Filter holder 1 has rectangular opening 1-5, guarantees in the time that gland 2 freely rotates, and ear shape shell fragment 2-1 can not touch filter holder.
As shown in Figure 2, the main body 2-A of gland 2 uses the thick stainless steel substrates of 0.3mm, adopts sheet metal process to process, and to grow limit peripheral distance consistent for the frame 1-1 that encloses of the long limit of gland inner distance and filter holder, and the plus tolerance of getting 0.05mm; One end of main body 2-A is the driving lever 2-5 for stirring gland 2, and the other end is processed into two ear shape shell fragment 2-1, and while stirring gland 2, dome latch 3 can back down the protruding position C of ear shape shell fragment 2-1, makes it enter recess A or B, respectively unclamping or stationary state of corresponding gland.Size and the distance of recess A, B and protruding position C should meet in the time of stationary state, and two shell fragment 2-2 are above the two ends of rectangle optical filter.
As shown in Figure 3, respectively there is 1 shell fragment 2-2 at the two ends of described gland 2, adopt the sheet metal process of 0.2mm copper sheet to process, and are then welded on the main body 2-A of gland 2, distance between two shell fragments should ensure that at gland 2 shell fragment 2-2 is above the two ends of rectangle optical filter during at stationary state.
As Fig. 3, shown in 4, described gland 2 differs from both sides, ear shape shell fragment 2-1 one end the fixture block 2-3 of 1 pair of projection, it is bent out by the main body 2-A of gland 2, and in the time stirring gland 2 rectangle optical filter is installed, fixture block 2-3 inserts the draw-in groove 1-4 of filter holder 1, make shell fragment 2-2 keep elastic force, fixing optical filter; Described gland 2 has an about 0.5*1.8mm rectangular opening 2-4 in same one end of ear shape shell fragment, the length of this rectangular opening can not be too little, should ensure that gland 2 can be fixing and unclamp two states and move freely, can not be oversize, ensure fixing and unclamping under two states, what gland 2 was too large becomes flexible.
Described a pair of dome latch 3(is as shown in Figure 5), the cylinder that bottom 3-1 is high 0.6mm, diameter of section is 0.5mm, gets the minus tolerance of 0.05mm; The high 0.35mm of top 3-2, through dome processing, maximum cross-section diameter is 0.7mm.Dome latch 3 is through the rectangular opening 2-4 of gland 2, insert the circular hole 1-2 of filter holder 1, and by itself and filter holder 1 firm welding, now, gland 2 connects together with filter holder 1, and gland 2 can be around 3 translations of dome latch and rotation (as shown in Figure 6).The top of dome latch 3 should exceed salient point C lowermost end 0.2～0.3mm of ear shape shell fragment 2-1.
When rectangle optical filter is installed, first make gland 2 in releasing orientation B, picked up, then rectangle optical filter is placed on and is enclosed in frame 1-1, then put down gland 2(as shown in Figure 7), pin driving lever 2-5, it is allocated to stationary state A from releasing orientation B, and fixture block 2-3 inserts in the horizontal cut of draw-in groove 1-4 simultaneously, makes shell fragment 2-2 keep elastic force, push down optical filter, now just complete the installation (as shown in Figure 9) of optical filter; When dismounting optical filter, gland 2 is allocated to releasing orientation B(as shown in Figure 8 from stationary state A), then pick up gland 2, take out optical filter.
Above content is the detailed description of this patent being done in conjunction with the mounting condition of the rectangle optical filter running in real work, can not assert that the concrete enforcement of this patent is confined to these explanations.To various equivalent modifications, adjustment, increase and decrease or the replacement done according to actual optical filter service condition, all should be considered as belonging to the protection domain of this patent.
