Such as Fig. 9, Figure 10 and shown in Figure 11, Fig. 9 is the structural representation of resetting-mechanism 8 among Fig. 4; Figure 10 is the structural representation that fitting seat 4 slides in return stroke among Fig. 4; Figure 11 is the structural representation that block 63 drives dwang 2 among Figure 10.
Clear in order to explain, at first the sliding stroke of fitting seat 4 is explained: sliding stroke comprises glide direction locking stroke and return stroke in opposite directions;
Locking stroke: push away handle 66 and promote fitting seat 4 is slid into lockable mechanism 7 locking fitting seats 4 by initial state stroke;
Return stroke: fitting seat 4 is removed locking, is slid into the stroke of initial state by lockup state.
Then tell about resetting-mechanism 8: resetting-mechanism 8 is used in return stroke again, promotes fitting seat 4 and returns back to initial state, resets.
Resetting-mechanism 8 comprises that the second Returnning spring 81, the second Returnning springs 81 are located in the base 6, and an end of the second Returnning spring 81 and base are 6 affixed, the other end and fitting seat 4 are affixed;
In the locking stroke, promotion lower compression the second Returnning spring 81 that fitting seat 4 is pushing away handle 66;
In return stroke, the second Returnning spring 81 discharges its elastic potential energy promotion fitting seat 4 and returns back to initial state, resets; And in return stroke, blade 9 cutting optical fibres, ratchet mechanism 5 is with cutting blades 9 single direction rotation set angles afterwards, changes the surface of contact of blade 9 cutting optical fibres.
In addition, free end 64 is rotatably connected to handle 67, handle 67 is provided with card splenium 68, card splenium 68 is used for the end that butt stretches out the snak link 72 of penetration hole 61, handle 67 is used for pressing snak link 72 when card splenium 68 butt snak link 72, leave penetration hole 61 so that snak link 72 promotes spring latch 71, remove locking.
Next is explained to the course of action of the ratchet mechanism of the present embodiment, may further comprise the steps:
S1: optical fiber to be cut is positioned on the base 6, closed loam cake 62, optical fiber is between loam cake 62 and base 6;
S2: promote fitting seat 4 and slide;
S3: in the sliding stroke of fitting seat 4, blade 9 cuts draws optical fiber; And ratchet mechanism 5 stopped in the sliding stroke of fitting seat 4, and then ratchet mechanism 5 is rotated; Stop releasing, then ratchet mechanism 5 resets and is with cutting blade 9 rotations, changes the surface of contact of blade 9 cutting optical fibres.
In the method for the cutting optical fibre of ratchet mechanism of the present utility model, specifically may further comprise the steps:
S1.1: rotary upper cover 62 pushes away handle 66 and promotes fitting seat 4 by the initial state slip, simultaneously fitting seat 4 compression resetting-mechanisms 8 in the rotation process;
S1.2: slide into lockable mechanism 7, then lockable mechanism 7 is with fitting seat 4 lockings;
S1: optical fiber is positioned on the base 6, closed loam cake 62, optical fiber is between loam cake 62 and base 6;
S2: press free end 64, remove the locking of 7 pairs of fitting seats 4 of lockable mechanism, fitting seat 4 slides under the promotion of resetting-mechanism 8 behind the releasing locking, slides into initial state and resets;
S3: in the return stroke of fitting seat 4, blade 9 cuts draws optical fiber; And ratchet mechanism 5 is rotated when being subject to stopping; Stop releasing, then ratchet mechanism 5 resets and is with cutting blade 9 rotations, changes the surface of contact of blade 9 cutting optical fibres.
Further:
1, opens loam cake 62.In the process of opening loam cake 62, push away handle 66 promotion fitting seats 4 and slide in the locking stroke.In the locking stroke, lockable mechanism 7 is with locking fitting seat 4: mounting hole 41 is relative with penetration hole 61, and then spring latch 71 springs into penetration hole 61 and spring latch 71 and snak link 72 butts, with locking fitting seat 4.In above-mentioned locking stroke, promotion lower compression the second Returnning spring 81 that fitting seat 4 is pushing away handle 66, by the time behind the lockable mechanism 7 locking fitting seats 4, the compressive deformation of the second Returnning spring 81 is to maximum, and because of the locking of lockable mechanism 7, the elastic potential energy that the second Returnning spring 81 produces can not promote fitting seat 4 at this moment and reset.Optical fiber to be cut is placed on the base 6.
2, closed loam cake 62, closed rear card splenium 68 and the end butt that stretches out the spring latch 71 of penetration hole 61.Press handle 67, then handle 67 presses snak link 72, leaves penetration hole 61 so that snak link 72 promotes spring latch 71, removes locking.
3, remove because of locking, the elastic potential energy that the second Returnning spring 81 produces will promote fitting seat 4 and slide in return stroke, reset.In this return stroke, dwang 2 will be subject to stopping of block 63.Because being subjected to stopping of block 63, dwang 2 will be to the direction opposite with return stroke (locking stroke directions) rotation, and after the rotation ratchet 21 and ratchet 3 cards and.Stop that releasing (opens loam cake 62, block 63 is separated with dwang 2), then dwang 2 resets under the restoring force effect of the first Returnning spring 1, and dwang 2 promotes ratchet 3 one-way rotation, ratchet 3 band cutting blades 9 single direction rotation set angles, the surface of contact of change blade 9 cutting optical fibres.
Blade 9 single direction rotation set angles are by the angle decision of the gear teeth of ratchet 3, and also, if ratchet 3 peripheries have 12 equally distributed gear teeth, blade 9 will rotate 12 times in a rotation period (circumference) so, rotate 30 degree at every turn.Certainly, it is 12 that the quantity of the gear teeth of ratchet 3 also is not limited to, and also can be other quantity, such as being 16 or 6 etc.
In certain embodiments, such as Fig. 2, shown in Figure 3, also a non-return card hand 5 can be set below ratchet 3 again, non-return card hand 5 butt ratchets 21 are used for 3 counter-rotatings of restriction ratchet, so that ratchet 3 single direction rotations.This non-return card hand 5 can limit the reverse rotation of ratchet 3, also is that ratchet 3 can only rotate along the locking stroke directions, and can not be along the return stroke direction rotation.In addition, need to prove the ratchet mechanism of the present embodiment, in the locking stroke, dwang 2 can not be subject to stopping of block 63, and blade 9 can not rotate yet, and problem, the problem includes: flimsy problem if avoided like this dwang 2 to be subjected to its sense of rotation opposite effect power.In return stroke, dwang 2 band cutting blades 9 single direction rotation set angles, the surface of contact of change blade 9 cutting optical fibres, and cutting optical fibre.
In certain embodiments, also can be: ratchet mechanism comprises the first Returnning spring 1, dwang 2 and ratchet 3; The first Returnning spring 1 is connected on the dwang 2, and dwang 2 is rotationally connected with ratchet 3, and dwang 2 is provided with the ratchet 21 that cooperates with ratchet 3.Placement is same as described above.In these embodiments, it is optical fiber cleaver that the purposes of ratchet mechanism is not limited to, and also can be to be used on other equipment.
The above is described embodiment of the present utility model by reference to the accompanying drawings; but the utility model is not limited to above-mentioned embodiment; above-mentioned embodiment only is schematic; rather than restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; not breaking away from the scope situation that the utility model aim and claim protect, also can make a lot of forms, these all belong within the protection of the present utility model.
