Description
Technical field
The utility model relates to optical fiber shearing, in particular to a kind of optical fiber cutter.
Background technique
Optical fiber cutter is the tool for cutting bare fibre during fused fiber splice.
Authorization Notice No. is that the Chinese patent of CN202502269U discloses a kind of optical fiber cutter, including knife rest, top cover,
Carrying fine slot, blade guide rail and blade further includes for returning cutter mechanism for what is automatically reset after optical fiber shearing.By the guarantor outside optical fiber
Bare fibre is placed in the fine slot of load after peeling off and cuts bare fibre by moving blade guide rail by sheath, and using returning, cutter mechanism is automatic
It resets and completes shearing.
But need to peel off using dedicated wire stripper there are also one layer of coat outside bare fibre, tool is needed replacing among this
It operates not simple enough.
Utility model content
The purpose of this utility model is to provide a kind of optical fiber cutters, it has the function of peeling coat off.
The above-mentioned purpose of the utility model has the technical scheme that a kind of optical fiber cutter, including
Pedestal is covered for fixing the upper cover of optical fiber on pedestal, and the shearing component for cutting optical fiber passes through between upper cover and pedestal
Magnetism is stained with conjunction, is provided on upper lid and helps for pry open upper cover and pedestal from bar, described help is provided with from bar for ring cutting
The bark knife of optical fiber coating.
By using above-mentioned technical proposal, coat is peeled off by bark knife after the protective layer of optical fiber is peeled off, it will
Bare fibre is placed on after pedestal fixes optical fiber and is cut optical fiber by cutting assembly.It saves replacement tool and peels coat off
The step of, it operates simpler, while bark knife setting being helped from bar, using helping hinged from bar itself and rotation function
It can be carried out the debarking action of coat, the processing technology of saving has saved a large amount of cost, while helping that be both able to achieve from bar will be upper
It covers the removing that separates with pedestal, and can be carried out coat and realizes one and dual-purpose reached making full use of for optical fiber cutter.
The utility model is further arranged to: helping hinged with upper cover from the middle part of bar, one end and base contacts, the other end are set
There is hand-held part, bark knife, which is arranged in, to be helped from bar and the hinged position of upper cover.
By using above-mentioned technical proposal, pushes hand-held part pedestal can be made to separate with upper cover using lever principle, solve
Upper cover and pedestal are stained with conjunction due to magnetism and lead to the problem of being not easily separate.It utilizes and is helped from the hinged reality between bar and upper cover simultaneously
The peeling work of existing bark knife.
Further, bark knife includes helping from the bottom knife for corresponding to upper cover position on bar and cooperating bottom knife on upper lid
The cutter of ring cutting coat.
Through the above technical solutions, can be realized ring cutting coat by the cooperation of cutter and bottom knife.
Further, help from bar altogether there are two, be located at upper cover two sides, and two help and rotate synchronously from bar with respect to upper cover.
Through the above technical solutions, be located at helping for upper cover two sides is able to maintain balance from bar in operation.It drives simultaneously
Helping for dynamic side can drive helping for the other side to carry out peeling work from the bark knife between bar and upper cover from bar, increase power
Arm.
Further, being arranged side by side between cutter and bottom knife has for coat that ring cutting diameter is 0.25mm, straight
The protective layer that the tail optical fiber and diameter that diameter is 0.9mm are 3mm sets fine mouth.
It sheared, operated more through the above technical solutions, the bark knife can peel the three-layer protection layer of optical fiber off
Conveniently, the step of reducing replacement tool.
Further, optical fiber storage box includes that hinged and lid is located on box body positioned at the box body of base side and with box body
Storage lid.
Through the above technical solutions, the optical fiber being sheared covers storage lid after falling in optical fiber storage box can prevent optical fiber
Fall.
Further, cutter groove is provided on pedestal, shearing component is located at below cutter groove and can do reciprocal fortune in cutter groove
It is dynamic, it is provided on upper lid and shearing component is prevented to shear the limit assembly resetted after optical fiber, cooperation limit is provided on shearing component
The block board of component.
Through the above technical solutions, fiber cross-sections are still at cutter groove after bare fibre is cut, if shearing component is multiple
Position, which may contact again and damage to generate after optical fiber is cut, connects section, and it is defeated to influence light.
Further, limit assembly includes the elastic component being arranged on upper lid, the connecting plate being connected on elastic component, connection
Extend the limit plate with block board cooperation on plate.
Through the above technical solutions, covering upper cover, limit plate is supported with block board when shearing component is in initial position
It connects, when shearing component is moved to extreme position, block board and limit plate misplace, and are supported limit plate by the elasticity of elastic component
Out, being stuck in block board side prevents shearing component from resetting, and when upper cover is opened, reset assembly again resets shearing component.
Further, elastic component includes the insertion pipe across upper cover setting, the spring in insertion pipe, and is fixed on
The fixed block of upper exterior surface, spring one end are connected to insertion bottom of the tube, and the other end is connected on fixed block, are embedded at pipe nozzle
Restricted insertion pipe is arranged will not be popped up the limit edge of upper cover by spring, and insertion bottom of the tube is fixed on connecting plate.
Through the above technical solutions, by spring be embedded in insertion pipe in, prevent double swerve or the deformation of spring, to spring into
Row protection, increases the service life of spring, while the elastic force of spring being allowed uniformly to be added on connecting plate, allows the telescopic effect of connecting plate
More preferably.
Further, shearing component is additionally provided with for shearing the reset assembly for automatically resetting sliding component after optical fiber, institute
It states reset assembly and includes and the magnet of sliding component initial position and extreme position is set, and cooperate on shear knife above-mentioned
Magnet has the magnet to initial position movement tendency using reset assembly.
Through the above technical solutions, automatically reseting for sliding component is realized by the interaction force of magnet, it is on the one hand convenient
Cost is saved in installation.
In conclusion the utility model has the following beneficial effects:
