Specific embodiment

The door lock embodiment that Fig. 1 and Figure 16 represents, including lock body 1 and lock 2, lock body 1 includes lock 100, main dead bolt machine Structure, pair spring bolt mechanism, main spring bolt mechanism definition is can be opened and closed by key, and pair spring bolt mechanism is orientated as by interior handle or held outward Handss open and close.Lock 2 includes main dead bolt button 900, secondary dead bolt button 200.

Main spring bolt mechanism includes lead 140, main dead bolt 110, main dead bolt link rod 120, and pair spring bolt mechanism includes secondary dead bolt 160th, secondary dead bolt link rod 170 and secondary dead bolt stopping means 191.Remain retracted in lock 100 under the ordinary state of secondary dead bolt 160 In, it is subject to acting on of secondary dead bolt stopping means 191 all the time, specifically secondary dead bolt stopping means 191 include slide block 180, Fixed block 192 and stage clip 193, stage clip 193 two ends are connected to fixed block 192 and slide block 180 respectively it can be seen that secondary dead bolt 160 is the poised state being limited by stage clip 193 under normal conditions, and slide block 180 is then interaction relation with secondary dead bolt link rod 170, secondary lock Tongue link rod 170 and slide block 180 cannot overcome stage clip 193 suppression in the state of the equilibrium, and therefore secondary dead bolt link rod 170 is limited System bottom in FIG, secondary dead bolt 160 contracts in lock body 1.

Lock 2 is fixedly mounted on doorframe, is static for lock 2 doorframe relatively, the major-minor dead bolt button 900 of lock 2, 200 essential structure is button hole, for passing in and out respectively for major-minor dead bolt 110,160, to complete the overall process opened the door and close the door.

Secondary dead bolt 160 with secondary dead bolt link rod 170 fixing assembling it is intended that expression both be the relation being fixedly connected, this enforcement In example, involved fixing assembling should be all that identical understands.

Secondary dead bolt 160, secondary dead bolt link rod 170, overall lock relatively 100 activity of slide block 180 are assembled, and premise herein is Lock 100 under confined state be static installation on door, therefore secondary dead bolt 160, secondary dead bolt link rod 170, slide block 180 whole Body is that lock 100 is longitudinally up and down relatively in FIG, and main dead bolt 110 and main dead bolt link rod 120 are also longitudinally to live up and down in the same manner Dynamic.

Secondary dead bolt 160, the overall opposing slider 180 activity assembling of secondary dead bolt link rod 170, slide block 180 is to be socketed in secondary lock Outside tongue link rod 170, because secondary dead bolt link rod 170 and slide block 180 are the relations being flexibly connected, secondary dead bolt 160, secondary dead bolt connection Space can be produced because of the priority transmission of activity command between the entirety of bar 170 and slide block 180.And thus secondary dead bolt link rod 170 and slide block 180 both can produce contact part respectively each other, be that secondary dead bolt link rod 170 has secondary dead bolt link rod contact part 171, slide block 180 has slide block contact part 181, and contact part herein should be understood to contact or abuts, rather than the containing of opposing Justice.Impact noise is just produced by this two contact parts.

Secondary dead bolt link rod contact part 171 is after secondary dead bolt link rod 170 assembles, slide block 180 position that can touch, and is Slide block contact part 181, it is mutually echoed with slide block contact part 181, and slide block contact part 181 is also and secondary dead bolt link rod supports in the same manner Contact portion 171 is mutually echoed.

Figure 10 to Figure 12 illustrates slide block 180 and includes slide block end face 182, and secondary dead bolt link rod 170 includes mobile jib 172 and spacing Block 173, the lateral cross section of mobile jib 172 is circle, and the lateral cross-sectional area of limited block 173 is more than the lateral cross-sectional area of mobile jib 172, Secondary dead bolt link rod contact part 171 is located at limited block 173, and slide block contact part 181 is located at slide block end face 182, and elastomeric element includes pair Dead bolt external member 600, secondary dead bolt external member 600 includes exterior feature 610 and secondary dead bolt external member gabarit 620, secondary dead bolt external member in secondary dead bolt external member Interior wide 610 is circle, and in secondary dead bolt external member, wide 610 diameter is less than the transverse cross-sectional diameter of limited block 173, wide in secondary dead bolt external member 610 sockets are assemblied in outside mobile jib 172.

Under normal circumstances, the side wall of the secondary dead bolt link rod 170 of Figure 10 and Figure 11 and slide block 180 socket also can be secondary dead bolt connection Bar contact part 171, because stress is more uniform in the slipping of opposing slider 180 at this, can be considered the relation of friction, produces Slight noise, but for secondary dead bolt link rod 170, limited block 173 and slide block 180 have the effect of shock, limited block 173 In opening-closing process, stress is more swift and violent, is considered as shock relation between the two, and the strike note being sent substantially can be more than aforementioned The noise that friction produces.From the angle of noise reduction, if the noise clashing into can be reduced, then produced noise may be used To accept, because the noise between friction is can be ignored, certainly ideally will be whole for the noise of friction and shock Weaken.

Tentatively the present embodiment only considers to solve the impact noise of limited block 173 and slide block 180, just as it was previously stated, first not examining Consider both and be slidably socketed the friction noise at position.

Therefore, the secondary dead bolt buffer unit of lock 100, isolation is for confined state, and slide block 180 is enclosed within secondary lock After tongue link rod 170, both are between isolated by this secondary dead bolt buffer unit assembling, it is to avoid both directly contacts.That Its confined state has three kinds of possibility: the first is assemblied in secondary dead bolt link rod 170；It two is assemblied in slide block 180；Its three are It is assemblied in lock 100.And on the premise of passing over cost, it is all can be with fixing assembling or work with the relation of three Dynamic assembling.

The secondary dead bolt buffer unit of the present embodiment includes elastomeric element.Elastomeric element herein does not refer to mechanical field technology Noun spring, but refer to the material with elastic deformation property.By the elasticity absorption of elastomeric element, for obtaining anticipation Buffering effect, conveniently produces and with low cost.

Elastomeric element is made up of plastic cement or plastics or rubber or synthetic fibers.

The secondary dead bolt link rod 170 of the present embodiment and secondary dead bolt external member 600 relative motion assembling, secondary dead bolt external member 600 is phase The loose joint relation that secondary dead bolt link rod 170 is rotated.But the diameter due in secondary dead bolt external member wide 610 is less than limited block 173 Transverse cross-sectional diameter, secondary dead bolt external member 600, without departing from secondary dead bolt link rod 170, can reduce assembling and production difficulty further.

The lateral cross-sectional area of secondary dead bolt external member gabarit 620 is more than the lateral cross-sectional area of limited block 173.Secondary dead bolt external member The lateral cross section of the lateral cross section of gabarit 620 or limited block 173 can be illustrated by Figure 12, employs left and right directions in Figure 12 The section of s is as lateral cross section it can be seen that the lateral cross-sectional area of limited block 173 is more than the horizontal stroke of secondary dead bolt external member gabarit 620 To area of section, it is up-narrow and down-wide shape.

Why embodiment is only made to the concrete shape of in secondary dead bolt external member wide 610 and mobile jib 172 is all the restriction of circle, It is because that limited block 173 and secondary dead bolt external member gabarit 620 are need not to be set as justifying, and only need to meet aforesaid lateral cross-sectional area Condition.

A little variation can be made on the basis of above-described embodiment, such as by secondary dead bolt link rod 170 and secondary dead bolt external member 600 Geo-stationary assembles.Specifically secondary dead bolt external member 600 is securely fitted in the limited block 173 of secondary dead bolt link rod 170, permissible Raising buffers noise reduction but assembly difficulty is higher.

The flexible structure of embodiment, difference is secondary dead bolt external member 600 and slide block end face 182 fixing assembling, specifically It is the lateral cross-sectional area more than mobile jib 172 for the lateral cross-sectional area of limited block 173, secondary dead bolt link rod contact part 171 is located at limit Position block 173, slide block contact part 181 is located at slide block end face 182, secondary dead bolt external member 600 and slide block end face 182 fixing assembling, secondary lock The entirety socket of tongue external member 600 and slide block 180 is assemblied in outside mobile jib 172, in secondary dead bolt external member between wide 610 and mobile jib 172 There is space, this space is the mass activity for the relatively secondary dead bolt external member 600 of mobile jib 172 and slide block 180.Compare enforcement Example, both for secondary dead bolt external member 600 and limited block 173 fixing assembling, 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, and so-called external member is not the ring of closure, Present invention is primarily targeted at solution impact noise, and the noise of aforementioned friction is then secondary.Secondary dead bolt external member 600 pole The form at end is that form is several paster shapes when its fixing assembling relation, is fitted in the slide block contact part 181 of slide block 180 Or the secondary dead bolt link rod contact part 171 of pair dead bolt link rod 170, also can play the effect of buffering collision of closed, but Comparatively speaking stress Not uniform.

The flexible structure of embodiment, can also be with reference to kind of an embodiment, respectively in secondary dead bolt link rod contact part 171 and slide block Secondary dead bolt external member 600 is set up on contact part 181, and is the relation of fixing assembling with them respectively.By two secondary dead bolt external members 600 can substantially reduce noise it may be said that being almost not have noise, but relative cost also considerably increases, corresponding dress Join difficulty to be also significantly increased.

Figure 13 to Figure 20 represents the magnetic self-absorbing structure details of door lock, and lock body 1 includes secondary dead bolt magnet 10, secondary dead bolt block piece 11, secondary dead bolt 160 includes secondary lock tongue cavity 161, and secondary lock tongue cavity 161 includes secondary lock tongue cavity opening 162, secondary dead bolt magnet 10 and secondary lock Tongue block piece 11 receiving is assemblied in secondary lock tongue cavity 161, and secondary dead bolt block piece 11 is assemblied in secondary dead bolt magnet 10 and secondary lock tongue cavity opening 162 Between, secondary dead bolt block piece 11 and secondary dead bolt 160 fixing assembling.

Secondary lock tongue cavity opening 162 direction is in the right side side of Figure 14, and being arranged on left side is also equally possible scheme, should Secondary lock tongue cavity 161 can be considered as a narrower blind hole, is primarily used to as secondary dead bolt magnet 10 and secondary dead bolt block piece 11 The space laid, secondary dead bolt magnet 10 and secondary dead bolt block piece 11 are all flake, but secondary lock tongue cavity 161 can not be from secondary dead bolt 160 top end faces in fig. 14 are too remote, and otherwise magnetic force can weaken.It is same that secondary dead bolt block piece 11 is typically designed as secondary dead bolt 160 Kind material, shaping style of the same race, it is believed that being to get lodged in secondary dead bolt magnet 10 in secondary lock tongue cavity 161, is being consolidated with secondary dead bolt 160 Surely, after assembling, secondary lock tongue cavity opening 162 is difficult to observe the harmony it is ensured that visual effect by being filled up by it.
