Description
Technical field
The present invention relates to field of lockset more particularly to a kind of lock body mechanisms with fast-escape function.
Background technique
People increasingly pay attention to this safety problem of the fast-escape under emergency case, occur on the market quickly
The door lock of escape, although the function that these door locks are unlocked for a key, but there are deficiencies below:
(1) part lock body band safety tongue, people rotate the safety tongue knob in lock panel safety tongue with hand in door at present
It gets (locking) to retract (unlocking) safety tongue, pressure gate lock handle can not retract safety tongue, occur emergency (such as fire)
Shi Kaimen is slow, first to rotate safety tongue knob and safety tongue is opened, then pushes the main lock tongue of hand handle and latch bolt opening, that is to say, that
It wants two movements all lock tongues can just be opened, can not achieve personnel and quickly flee danger condition.
(2) existing fast-escape function setting is in rear of lock body, because space limitation can not lean on structure real completely in mechanism
It now retracts, is flicked by torsional spring, it is unreliable.
Above-mentioned in order to overcome the shortcomings of, we have invented a kind of lock body mechanisms with fast-escape function.
Summary of the invention
Goal of the invention of the invention is that safety tongue can not be retracted by solving existing part lock body door lock handle, need two
A movement can just open all lock tongues, the setting of existing fast-escape function is in rear of lock body, because space limitation can not be complete
It realizes and retracts in mechanism, insecure problem is flicked by torsional spring.Its specific solution is as follows:
A kind of lock body mechanism with fast-escape function, including lock housing, positioned at the lock housing side side plate, be located at institute
State the insurance hypistoma component of side plate one end, positioned at the latch bolt component of the side plate other end.It further include below the insurance hypistoma component
Dentation plectrum, one end be located at the dentation plectrum in the following, the first lower pillar socket of the other end and latch bolt plectrum component solution
Pull rod is locked, the left end for unlocking pull rod is equipped with the first kidney slot, and the first kidney slot is socketed the second lower pillar of the dentation plectrum, solution
The middle part for locking pull rod is equipped with the second kidney slot, and it is parallel contour that the second kidney slot covers two be arranged in the middle part of the lock housing lower case
Pillar on, a kidney-shaped tabletting is set on pillar again.The latch bolt plectrum component is placed on the main tongue plectrum group in handle axis
The upper surface of part, the plectrum of the latch bolt plectrum component are stirred with the tail end slide plate of the latch bolt component and are connect.
It further include the shifting block component engaged with the dentation plectrum, shifting block component lower part, which is equipped with, turns tooth, and top is equipped with angle
For the first shifting block and the second shifting block of 60-80 degree, the first shifting block and the second shifting block can be matched with the insurance hypistoma component tail portion
It dials hook and stirs connection, the both ends of the shaft in the middle part of shifting block component is through at the safety tongue knob hole of the upper and lower casing of the lock housing respectively
In.
It further include being located at the shifting block component right, the torsional spring locating rack being mounted in the lock housing lower case square hole is turned round
Spring locating rack lower left corner is cased with the first annulus of torsional spring, and the middle part of torsional spring is free second annulus, and the other end of torsional spring is equipped with
Third annulus, third annulus cover on the head of pin, and the logical of first shifting block end is from bottom to top inserted in the tail portion of the pin
Kong Zhong.
Third kidney slot is equipped in the middle part of the insurance hypistoma component, third kidney slot and the circle of the end of the dentation plectrum are logical
It is inserted in the positioning column in the lock housing lower case together in hole.
Further, the upper surface of described insurance hypistoma component is equipped with upper pillar, and convex column sleeve is in the cunning of the lock housing upper housing
In slot, it is against on the right side of the insurance hypistoma component on the left part step of the torsional spring locating rack.
Further, the torsional spring locating rack is enclosed with the U-shaped board on the left side and is connect by the asymmetric two blocks of L-type plates in front and back,
L-type plate right lower quadrant is respectively provided with a square foot.
Further, the angle of 100-140 degree is formed between the first annulus of the torsional spring, third circle and the second annulus,
Three annulus are located in approximately the same plane.
Further, the unlock pull rod can rotate with handle and the latch bolt plectrum component and slide to the right, can be with handle
Hand and latch bolt plectrum component reset are slided to the left again.When insure tongue when, the shifting block component counterclockwise, on the one hand
It stirs the insurance hypistoma component to stretch out outside the side plate, the dentation plectrum is on the other hand driven to rotate clockwise, described the
Two lower pillars are located at the left end of first kidney slot, rotate clockwise handle at this time and are able to rotate the main tongue plectrum component, institute
Latch bolt plectrum component is stated, makes main tongue component, the latch bolt component, be retracted in the side plate, while the unlock pull rod is slided to the right
Dynamic, first kidney slot drives the described second lower pillar to turn right, and the dentation plectrum counterclockwise drives described dial
Block assembly rotates clockwise, and the insurance hypistoma component is retracted in the side plate.When do not insure tongue when, the described second lower pillar
Positioned at the right end of first kidney slot, the unlock pull rod is to the right, when sliding to the left again, not will drive the described second lower pillar
Rotation.
In conclusion being had the advantages that using technical solution of the present invention
This programme solves existing part lock body door lock handle and can not retract safety tongue, needs two movements just can be with
All lock tongues opening, the setting of existing fast-escape function in rear of lock body, because space limitation can not be realized in mechanism completely
It retracts, insecure problem is flicked by torsional spring.This programme has the advantage that
(1) lock body fast-escape function retracts all lock tongues (including safety tongue) when pushing door lock handle.
(2) main lock tongue is got and is retracted under two states, and safety tongue individually can be got and retract.
(3) fast-escape structure realizes that the first kidney slot of unlock pull rod is dialled to the right on the middle part of lock body lock housing, mechanism
Dynamic second lower pillar, the second lower pillar make dentation plectrum to rotation, drive shifting block component to rotate clockwise, the first shifting block counterclockwise
Insurance hypistoma component is retracted in side plate with the second shifting block, torsional spring is only used as the effect of auxiliary positioning.
It can be seen that the structure design of this programme is simple, reliable, swift to operate, highly-safe, real key escape is realized
Function.
