Description
Technical field
The present invention relates to hinge fields, more particularly to a kind of magnetic ratchet hinge structure.
Background technology
Door and window can make the stability of frame poor, especially be blown by strong wind, door and window is just when opening due to hinge
It can automatically swing, or even can automatic locking.
To solve the above problems, also someone it is proposed that ratchet hinge structure, such as patent No. CN201020277002.2
Five grades of hinges, but it is difficult to perfect cooperation between the cam and ratchet of this hinge, so interim card is still more serious, especially
Bounce of the pawl per lattice has abnormal sound when being hinge rotation, could not reach smooth folding effect.
Invention content
The purpose of the present invention is being directed to the existing above problem, a kind of magnetic ratchet hinge with slow reply effect is provided
Structure.
Object of the invention can be realized by the following technical scheme:The present invention includes hinge one and hinge two, hinge one
It is connect by shaft between hinge two, the hinge one is the opposed fixed member for shaft, and hinge two is rotated with shaft, institute
The hinge one stated is equipped with pawl, and pawl is hinged with hinge one, and the shaft is equipped with ratchet, the ratchet distribution on ratchet
Account for the 1/6~1/3 of ratchet circumference, which is characterized in that be respectively provided with shift plate at the both sides clearing end of continuous ratchet on ratchet, the shift plate
Length be more than ratchet tooth it is long, at the shift plate to ratchet have spacing, the hinge one be equipped with permanent magnet, pawl tail
Portion be equipped with magnetic conductive board, when ratchet thereto a direction rotate and make pawl disengaging ratchet when, one of shift plate stirs pawl,
Make magnetic conductive board on pawl and permanent magnet close to and be attracted, low resilience return unit is equipped between pawl and ratchet.
The low resilience return unit includes the magnetic core being located inside ratchet, which is circular ring structure and and ratchet
Coaxially, the pawl head of pawl is divided into magnetic conductive metal, is set on the hinge one there are two connecting seat, is clipped between two connecting seats
Pawl, pawl is hinged with connecting seat, and connecting seat is equipped with forward and backward block piece, and forward and backward block piece limits the front and back rotation of pawl respectively
Maximum position.
When the magnetic conductive board is attracted with permanent magnet patch, when pawl upwarps and ratchet rotates, pawl is non-contact with ratchet.
The shift plate is on the outer ring tangent line of ratchet.
The shift plate length differs.
Compared with prior art, muting function of the present invention is good, and opening for door and window can be arbitrarily fixed under certain angle
Position is closed, reversely smooth can be folded hinge again after opening to the limit.

Part.
Specific implementation mode
The invention will be further described with reference to the accompanying drawings and examples.
Shown in Fig. 1-Fig. 2, the present invention includes hinge 1 and hinge 21, and hinge connection part 4, hinge are connected on hinge 21
There is sunk screw 5 again on connector 4.It is connected by shaft 3 between hinge 1 and hinge 21, hinge 21 is rotated with shaft 3, institute
Bearing 8 is connected in the shaft 3 stated, while hinge 1 is also connect with shaft 3.
It is set on the hinge 1 there are two connecting seat, pawl 6,6 connecting seat of pawl hinge is clipped between two connecting seats
It connects.Shaft 3 is equipped with ratchet 7, and the ratchet distribution on ratchet 7 accounts for the 1/6~1/3 of 7 circumference of ratchet, continuous spine on ratchet 7
It is respectively provided with shift plate 13 at the both sides clearing end of tooth, the length of the shift plate 13 is long more than the tooth of ratchet, and the length of two pieces of shift plates 13 is not
Deng there is spacing, the hinge 1 to be equipped with permanent magnet 11, permanent magnet 11 passes through interior hexagonal at the shift plate 13 to ratchet
Screw 12 is fixed on hinge 1, and 6 tail portion of pawl is equipped with magnetic conductive board 14, when a direction rotates and makes pawl ratchet 7 thereto
6 when being detached from ratchet, and one of shift plate 13 stirs pawl 6, make magnetic conductive board 14 on pawl 6 and permanent magnet 11 close to and be attracted.
When the magnetic conductive board 14 is attracted with the patch of permanent magnet 11, when pawl 6 upwarps and ratchet 7 rotates, pawl 6 and ratchet are non-contact.It is described
Shift plate 13 be on the outer ring tangent line of ratchet 7.
Low resilience return unit is equipped between ratchet 7 and pawl 6, it includes the magnetic core 9 being located inside ratchet 7, the magnet
Core 9 is circular ring structure and coaxial with ratchet 7, and the pawl head of pawl 6 is divided into magnetic conductive metal, connecting seat equipped with front catch member 10, after
Block piece 15, front catch member 10, backup member 15 limit the maximum position of the front and back rotation of pawl 6 respectively.When the ratchet of ratchet 7 pushes away spine
When pawl 6, the magnetic adsorbability of magnetic core 9 and pawl 6 has decaying, and backup member 15 is to limit the magnetic that pawl 6 is detached from magnetic core 9
Power range.In quick rotary hinge, pawl 6 will not be adsorbed onto on ratchet at once, therefore pawl 6 will not during rotation
It is engaged with each ratchet, not will produce excessive noise.When rotational positioning, pawl 6 can there are three processes, first, pawl 6 is separate
Ratchet 7, second is that being prevented a position, third, slowly being reached quick when magnetic force high point close to ratchet 7 during hinge vibrations
It is pull-in at ratchet, while pawl 6 leans against in front catch member 10.
Shown in Fig. 3-Fig. 5, when hinge is unfolded, using the one-way movement of 7 mechanism of ratchet, to realize consolidating for the random angle of hinge
It is fixed.When hinge expanded angle, which reaches, is more than 90 °, pawl 6 covers last tooth, and is jacked up by the shift plate 13 of 7 bottom of ratchet.Work as angle
When degree reaches 100 °, the magnetic conductive board 14 of 6 tail portion of pawl is sucked by permanent magnet 11, the power of torsional spring and the suction phase interaction of permanent magnet 11
With the position of pawl 6 remains unchanged.Ratchet 7 can rotate counterclockwise at this time, and hinge can also close up therewith, in 7 inverse time of ratchet
When needle rotates, the shift plate 13 of ratchet 7 gives 6 one power of pawl, and the magnetic conductive board 14 at 6 rear portion of pawl is allowed to be detached from the suction of permanent magnet 11,
And by the magnetic force of magnetic core 9, make ratchet engagement of the pawl 6 again with ratchet 7.
It should be understood that above example only expresses the preferred embodiment of the present invention, description is more specific and detailed
Carefully, but it cannot be construed as a limitation to the scope of the present invention;It should be pointed out that for the common skill of this field
For art personnel, without departing from the inventive concept of the premise, above-mentioned technical characterstic can be freely combined, can also be done
Go out several modifications and improvements, these are all within the scope of protection of the present invention;Therefore, all to be done with scope of the invention as claimed
Equivalents and modification, should all belong to the covering scope of the claims in the present invention.
