Description
Technical field
The present invention relates to latch, particularly relate to a kind of latch of soft unlatching.
Background technology
In order to can the parts of relative motion be fixed together two, lock is usually adopted.Latch in lock is due to when dead bolt touches lock ring, and dead bolt automatically can enter in lock ring and realize locking, so application is very extensively weary.
Chinese Patent Application No. be 2008801256179, date of publication be December 29 in 2009 day, be called in the patent document of " have independent grapple control protecgulum safety systems " and disclose a kind of latch.The basic structure of latch comprises dead bolt and lock ring, and being set to by dead bolt can along the mode of the axial stretching of lock ring or be designed to by lock ring can the mode of folding, realizes on the automatic locking in touching process.
Existing latch be all by handle with in both dead bolt and lock ring can move when touching and the one that realizes locking is rigidly connected and realize unblanking.Rigidly connected mode handle can only be arranged on from the place close to latch body; In the process of practical application, sometimes because the device space is narrow and small or the device space is complicated, the needs that rigidly connected mode can not meet the device space are installed, when carrying out remote opening time especially, and the poor reliability of transmission.
Summary of the invention
The present invention aims to provide a kind of latch that can carry out the good soft unlatching of remote space adaptability of opening, to solve the problem of existing latch space adaptability difference.
Above technical problem is solved by following technical proposal: a kind of latch of soft unlatching, comprise latch body, unlocking mechanism, and by flexible linking device that described latch body and described unlocking mechanism link together, described latch body comprises lock ring and dead bolt, described dead bolt and lock ring touch rear dead bolt can enter lock ring automatically, described flexible linking device comprises flexible sleeve, the shift transmission part displacement that unlocking mechanism inputs being passed to described lock ring or dead bolt and can deviate from from described lock ring to make described dead bolt is provided with in described flexible sleeve.When unblanking, drive unlocking mechanism, the displacement that unlocking mechanism produces is passed in the one that the process of unblanking is moved in both lock ring or dead bolt by shift transmission part, thus dead bolt and lock ring can be separated, to realize unblanking.
As preferably, described latch comprises locking frame, locking plectrum and locking card, described locking plectrum and locking card are all hinged with described locking frame, described locking card is provided with internal stop and outer baffle block, described lock ring is formed between described internal stop and outer baffle block, described locking plectrum is provided with the latch stoping described locking card rotating, and described shift transmission part links together with described locking plectrum.The structure of latch body is simple, and convenience when latch is opened is good, can adapt to installation needs of narrow space better, collides and the distortion action that produces in the process locked is little.
As preferably, described unlocking mechanism comprises handle, and described shift transmission part is drag-line, and one end of described shift transmission part is connected with described lock ring or dead bolt, the other end is fixed together with described handle.Convenient during making.
As preferably, described unlocking mechanism also comprises unlocking mechanism back-moving spring.Can realize automatically reseting, convenience is good.
As preferably, described unlocking mechanism also comprises opening mechanism holder and is arranged at the guide rod of opening mechanism holder, described taper knob is located at described guide rod, described unlocking mechanism back-moving spring is helical spring, described unlocking mechanism back-moving spring is sheathed on described guide rod, and described unlocking mechanism back-moving spring one end links together with described handle, the other end links together with described opening mechanism holder.Good reliability during operation.
Preferred as another, the sealing of described sleeve pipe one end is placed on described latch body, described unlocking mechanism comprises unlocking mechanism back-moving spring and sealing is located in the plunger of the sleeve pipe other end, and described displacement transferring member is be filled in sleeve pipe and liquid between plunger and latch body.In use procedure, plunger promotes liquid translation in sleeve pipe, the corresponding component translation in liquid-driving latch body or rotation, thus realizes unblanking.Displacement is transmitted by liquid, convenient during commutation.The better adaptability of lock to installing space.More laborsaving during driving.Wearing and tearing or tensile phenomenon can not be produced, good reliability as drag-line.
As preferably, described flexible linking device also comprises protection cylinder, and one end of protection cylinder is connected with the inner space of described sleeve pipe, is provided with piston and makes the piston reset spring of piston reset in described protection cylinder.Normally liquid is promoted and in the process that latch is unblanked when plunger, under the effect of back-moving spring, piston can not move in protection cylinder, if the displacement that plunger promotes liquid has exceeded set amount, then now liquid can increase the pressure of piston, and the result of increase is that piston moves towards the one end connected away from same sleeve pipe, and the amount of liquid flowed in protection cylinder increases, the pressure drop of liquid, thus play the effect preventing from being damaged lock inner part by excessive movement at latch.When moving outside plunger, under the effect of back-moving spring, the liquid entered because of overvoltage in protection cylinder flows back to sleeve pipe again, and the amount of liquid in retaining sleeve is constant.Safety is good.
As preferably, described unlocking mechanism also comprises opening mechanism holder and is connected to the handle of described plunger, and described handle is provided with locating piece, and described opening mechanism holder is provided with the locating hole matched with described locating piece.Latch can be made reliably to remain on enable possition, play prevent again on effect, good reliability.
The present invention has following advantage: by arranging sleeve pipe and arrange shift transmission part in sleeve pipe, makes can long-rangely to carry out during opened lock; Sleeve pipe is flexible structure, freely can alter course, therefore space adaptability is strong according to institute's usage space situation; Latch body can be carried out buried and closed installation, safety is good; Unlocking mechanism can be arranged on the position of convenient operation, comfortableness when unblanking can be improved.
