Slight noise, but for secondary dead bolt joining beam 170, limited block 173 and sliding block 180 have the effect of shock, limited block 173
Stress is more swift and violent in opening-closing process, is considered as shock relation between the two, and the strike note sent can substantially be more than foregoing
Rub the noise produced.From the angle of noise reduction, if the noise hit can be reduced, then produced noise may be used
To receive, because the noise between friction is can be certainly ideally whole by the noise for rubbing and hitting with ignored
Weaken.
The present embodiment one considers to solve the impact noise of limited block 173 and sliding block 180, just as it was previously stated, tentatively first not
Consider that both are slidably socketed the friction noise at position.
Therefore, the secondary dead bolt buffer unit of lock 100, isolation is for confined state, and sliding block 180 is enclosed on secondary lock
After tongue joining beam 170, both are isolated by secondary dead bolt buffer unit assembling therebetween, it is to avoid both directly contacts.That
Its confined state has three kinds of possibility：One is being assemblied in secondary dead bolt joining beam 170；Secondly being assemblied in sliding block 180；Its three are
It is assemblied in lock 100.And on the premise of cost is passed over, the relation of itself and three is all can be with fixing assembling or living
Dynamic assembling.
The secondary dead bolt buffer unit of the present embodiment one includes elastomeric element.Elastomeric element herein does not refer to mechanical field skill
Art noun spring, but refer to the material with elastic deformation property.Absorbed by the elasticity of elastomeric element, for being envisioned

It is both up-narrow and down-wide shape to area of section.
Why embodiment one only in secondary dead bolt external member exterior feature 610 and mobile jib 172 concrete shape make all be circle limit
It is fixed, it is because limited block 173 and secondary dead bolt external member gabarit 620 are need not to be set as circle, and need to only meet foregoing lateral cross section
Area condition.
Embodiment one also includes spring 190, and the one end of spring 190 and sliding block 180 contradict assembling, the other end of spring 190 and lock
Seat 100 contradicts assembling, and spring 190, which is socketed, to be assemblied in outside the entirety of secondary dead bolt joining beam 170 and secondary dead bolt external member 600.This spring
190 presence are in order that the reset of sliding block 180 and secondary dead bolt joining beam 170 is uniformly reliable.
A little variation can be made on the basis of above-described embodiment one, such as by secondary dead bolt joining beam 170 and secondary dead bolt external member
600 geo-stationaries are assembled.Secondary dead bolt external member 600 is specifically securely fitted in the limited block 173 of secondary dead bolt joining beam 170,
Buffering noise reduction can be improved but assembly difficulty is higher.The lateral cross-sectional area of secondary dead bolt external member gabarit 620 is more than for another example
The lateral cross-sectional area of limited block 173, both the secondary outer rim of dead bolt external member 600 can protrude secondary dead bolt under the outer rim of limited block 173, this structure
External member gabarit 620 can replace limited block 173 in longitudinally-moving, and the conflict relation rubbed with spring 190 reduces original limit
The friction noise of position block 173 and spring 190, further noise reduction.
The flexible structure of embodiment one, difference is secondary dead bolt external member 600 and the fixing assembling of sliding block end face 182, specific next
Say it is that the lateral cross-sectional area of limited block 173 is more than the lateral cross-sectional area of mobile jib 172, secondary dead bolt joining beam contact part 171 is located at
Limited block 173, sliding block contact part 181 is located at sliding block end face 182, secondary dead bolt external member 600 and the fixing assembling of sliding block end face 182, secondary
The overall socket of dead bolt external member 600 and sliding block 180 is assemblied in outside mobile jib 172, in secondary dead bolt external member exterior feature 610 and mobile jib 172 it
Between there is space, the space is the mass activity for the relatively secondary dead bolt external member 600 of mobile jib 172 and sliding block 180.Compare implementation
Example one, both for secondary dead bolt external member 600 and the fixing assembling of limited block 173, muting function is slightly worse, and assembly difficulty is higher.
Secondary dead bolt external member 600 is not limited to the concrete form of embodiment one, and so-called external member is not the ring-type of closure
Thing, it is a primary object of the present invention to solve impact noise, and the noise of aforementioned friction is then secondary.Secondary dead bolt external member 600
Most extreme form is that form is several paster shapes when its fixing assembling relation, is fitted in the sliding block contact part of sliding block 180
The secondary dead bolt joining beam contact part 171 of 181 or secondary dead bolt joining beams 170, can also play the effect of buffering collision of closed, but Comparatively speaking by
Power is not uniform enough.
The flexible structure of embodiment one, can also be with reference to kind of an embodiment one, respectively in the secondary He of dead bolt joining beam contact part 171
Secondary dead bolt external member 600 is set up on sliding block contact part 181, and is respectively the relation of fixing assembling with them.Pass through two secondary dead bolts
External member 600 can substantially reduce noise, it may be said that be almost no noise, but relative cost is also considerably increased, accordingly
Assembly difficulty be also significantly increased.
In addition as shown in figure 1, also including the main lock-tongue port 101 stretched for main dead bolt 110 on lock 100, and for secondary lock
The flexible secondary lock-tongue port 102 of tongue 160, main lock-tongue port lasso 103 and pair are arranged in main lock-tongue port 101 and secondary lock-tongue port 102 respectively
