Fig. 2 is a kind of right view of anti-loose insulation scissors of the present invention.
Embodiment
Refer to Fig. 1 and Fig. 2, the present inventor in order to preferably understand technical scheme,
It is described in detail below by specifically embodiment, and with reference to accompanying drawing：
A kind of anti-loose insulation scissors of the present invention includes insulated handle 1, scissors body 2 and insulated connecting rod 3.
Insulated handle 1 is a kind of major insulation part of anti-loose insulation scissors of the present invention, it is desirable to possesses insulating properties, absolutely
Edge handle 1 uses fiberglass, i.e. glass fiber forms in epoxy resin-impregnated matrix through high temperature pultrusion, possesses preferable insulation
Performance and mechanical performance.Its main performance includes：Density at 20 ± 2 DEG C is 2.1g/cm3, water absorption rate (23 ± 1 DEG C, 24h) is small
In equal to 0.05%, tensile strength is more than or equal to 1200MPa, and suction rainbow, which is tested, is more than or equal to 15Min, specific insulation (140 DEG C,
96h) it is more than or equal to 1010 Ω m, dc breakdown voltage is more than or equal to 50kV, and lightning impulse voltage (100kV) is more than or equal to 5,
Hot (143 DEG C ± 1 DEG C) of bending failure load test is more than or equal to 230%, anti-flammability V0.
Insulated connecting rod 3 includes scissor connecting part 32, and is bonded with insulated handle 1, and the ratchet parallel with insulated handle 1
Connecting portion 31.The top of ratchet connecting portion 31 is connected with the bottom of scissor connecting part 32, and is connected by buckle 4 and insulated handle 1
Connect.Between scissor connecting part 32 and ratchet connecting portion 31 in obtuse angle, scissor connecting part 32 is made to away from the lateral bending of insulated handle 1 one
Folding, insulated connecting rod 3 can revolve round the sun around insulated handle 1.
Scissors body 2 divides for operator first 21 and secondary cutter head 22.Wherein operator first 21 and secondary cutter head 22 are pivotally connected, head of operating
It is higher than the part of pivot connection in 21 top and the top of secondary cutter head 22, i.e. operator first 21 and secondary cutter head 22, is provided with opposite directions
Broached-tooth design, form the edge of a knife of scissors body 2.The lower end of operator first 21 is connected by fastening bolt with the top of insulated handle 1.
The lower end of secondary cutter head 22 is connected by fastening bolt with the top of the scissor connecting part 32 of insulated connecting rod 3.Operator first 21 and secondary knife
First 22 also with insulated connecting rod 3, and synchronization is revolved round the sun around insulated handle 1, easy to operation.
It is close to insulated handle 1 by setting, and the insulated connecting rod 3 that top is bent to the side away from insulated handle 1, and will
The lower end and the top of insulated connecting rod 3 of secondary cutter head 22 are fixed, and the occlusion stroke of secondary cutter head 22 is slower than the occlusion row of operator first 21
Journey, when wire is cut off in operator first 21, pair cutter head 22, will while wire is cut so as to realize only by conductor clamping
By the purpose of cutting conductor clamping.Operator first 21 and secondary cutter head 22 are using high-carbon steel forging and quenched processing.
The radial outside socket ratchet device 5 of insulated handle 1, ratchet device 5 are one by insulated connecting rod 3, control master
The powder operation device of cutter head 21 and the stroke of secondary cutter head 22.Ratchet device 5 includes the ratchet carriage for being socketed in the radial outside of insulated handle 1
51 and the ratchet mechanism (not shown) between ratchet carriage 51 and the radial direction of insulated handle 1, one end and the ratchet
Mechanism connects, the ratchet rocking bar 52 that extends radially out ratchet carriage 51 of the other end along ratchet carriage 51, the spine of insulated connecting rod 3
The bottom for taking turns connecting portion 31 connects the ratchet mechanism, passes through the push-and-pull up and down of the ratchet mechanism and ratchet rocking bar 52, band
Dynamic insulated connecting rod 3, unclamps secondary cutter head 22.
The ratchet mechanism is also connected with extending downwardly from the ratchet locking rocking bar 53 of ratchet carriage 51.
When ratchet locking rocking bar 53 is in plumbness, i.e., when parallel with the plane where the edge of a knife of scissors body 2, insulation
Connecting rod 3 is engaged with ratchet device 5, pulls ratchet rocking bar 52 to be gradually engaged operator first 21 and secondary cutter head 22, such as Fig. 1 institutes
Show.
When ratchet locking rocking bar 53 is vertical with the plane where the edge of a knife of scissors body 2, insulated connecting rod 3 and the ratchet
Mechanical unlocking, ratchet rocking bar 52 is pulled to unclamp operator first 21 and secondary cutter head 22.
To ensure a kind of the simple and practical of anti-loose insulation scissors of the present invention, operator first 21 and secondary cutter head 22 are engaged stroke
Different but position is relatively fixed, and ratchet device 5 is identical with the ratchet device of existing insulation scissors, but can control operator head simultaneously
21 and secondary cutter head 22.
Ratchet locking rocking bar 53 plays to be mainly reflected in the blocking function of ratchet device：
Ratchet locking rocking bar 53 is L-shaped, is divided into the vertical component effect 531 of ratchet mechanism connection, and with vertical component effect bottom
The horizontal part 532 of connection.The vertical component effect 531 of ratchet locking rocking bar 53 with ratchet rocking bar 52 in the same plane when, ratchet device 5
Not locking, ratchet rocking bar 52 can be freely to upper and lower push-and-pulls, so as to make operator first 21 and the pine of secondary cutter head 22 by insulated connecting rod 3
Open, but can not be engaged operator first 21 and secondary cutter head 22.
When the vertical component effect 531 of ratchet locking rocking bar 53 is vertical with the place plane of ratchet rocking bar 52, the locking of ratchet device 5,
Ratchet rocking bar 52 need to be pulled firmly repeatedly up and down, due to the single-direction transmission performance of ratchet device 5, so that operator first 21 and secondary knife
First 22 occlusion, but can not unclamp operator first 21 and secondary cutter head 22.
When needing to unclamp operator first 21 and secondary cutter head 22, ratchet device 5 is unclamped, makes hanging down for ratchet locking rocking bar 53
Straight portion 531 in the same plane, ratchet rocking bar 52 is pushed up, you can withdrawing with ratchet rocking bar 52.
A kind of anti-loose insulation scissors of the present invention, first 21 He of operator is controlled by ratchet device 5 and insulated connecting rod 3 simultaneously
Secondary cutter head 22, the stroke of secondary cutter head 22 is slower than the stroke of operator first 21, will be cut while wire is cut so as to realize
The purpose of conductor clamping.
A kind of anti-loose insulation scissors of the present invention, it be able to will be cut while cutting wire or removing foreign matter
Wire or foreign matter clamp, so as to prevent the potential safety hazard swung and triggered by wire or foreign matter, so as to greatly improve
The safety coefficient of livewire work, in terms of preventing that being cut wire swings and trigger potential safety hazard.
Those of ordinary skill in the art it should be appreciated that the embodiment of the above be intended merely to explanation the present invention,
And be not used as limitation of the invention, as long as in the spirit of the present invention, the change to embodiment described above
Change, modification will all fall in the range of claims of the present invention.
