Detailed description of the invention

The door lock embodiment that Fig. 1 and Figure 16 represents, including lock body 1 and snap close 2, lock body 1 includes lock 100, main dead bolt machine Structure, pair spring bolt mechanism, the definition of main spring bolt mechanism is can be opened and closed by key, and pair spring bolt mechanism is orientated as by interior handle or holds outward Hands opens and closes.Snap close 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 160, secondary dead bolt link rod 170 and secondary dead bolt stopping means 191.Remain retracted at lock 100 under the secondary ordinary state of dead bolt 160 In, it is all the time by the effect of secondary dead bolt stopping means 191, 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.

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

Secondary dead bolt 160 and the fixing assembling of secondary dead bolt link rod 170, it is intended that expressing both is the fixing relation connected, this enforcement Fixing assembling involved in example should be all identical understanding.

Secondary dead bolt 160, secondary dead bolt link rod 170, the overall movable assembling of lock 100 relatively of slide block 180, premise herein is Lock 100 under confined state is static mounted on a door, therefore secondary dead bolt 160, secondary dead bolt link rod 170, slide block 180 whole Body is that relative lock 100 is the most up and down in FIG, and the most main dead bolt 110 and main dead bolt link rod 120 are also longitudinally to live up and down Dynamic.

Secondary dead bolt 160, the movable assembling of overall opposing slider 180 of secondary dead bolt link rod 170, slide block 180 is to be socketed in secondary lock Outside tongue link rod 170, owing to 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 entirety and the slide block 180 of bar 170.And thus secondary dead bolt link rod 170 and slide block 180 both can produce contact part each other respectively, 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 that contact or abut rather than resist contains Justice.Impact noise is just produced by these two contact parts.

Secondary dead bolt link rod contact part 171 is after secondary dead bolt link rod 170 assembles, and slide block 180 position that can touch is Slide block contact part 181, it and the concord of slide block contact part 181 phase, in like manner slide block contact part 181 is also to support with secondary dead bolt link rod Contact portion 171 phase is 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 positioned at limited block 173, and slide block contact part 181 is positioned 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 in secondary dead bolt external member, secondary dead bolt external member Interior wide 610 is circle, and in secondary dead bolt external member, the diameter of wide 610 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 secondary dead bolt link rod 170 of Figure 10 and Figure 11 and the sidewall of slide block 180 socket also can be secondary dead bolt connection Bar contact part 171, because stress is more uniform in 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 sent substantially can be more than aforementioned Fricative noise.From the angle of noise reduction, if the noise clashed into can be reduced, then produced noise may be used To accept, because the noise between Mo Ca is can be uncared-for, certainly it would be desirable whole to friction and the noise clashed into Weaken.

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

Therefore, the secondary dead bolt buffer unit of lock 100, for isolation is for confined state, slide block 180 is enclosed within secondary lock After tongue link rod 170, this pair dead bolt buffer unit is assemblied in and both is isolated between the two, it is to avoid directly contact both.That Its confined state has three kinds of possibilities: 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 to fix assembling or live 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 character.By the elastic absorption of elastomeric element, it is used 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 owing in secondary dead bolt external member, the diameter of 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 gabarit 620 or the lateral cross section of limited block 173 can be illustrated by Figure 12, employ left and right directions in Figure 12 The cross 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 it is up-narrow and down-wide shape.

Why the concrete shape of exterior feature 610 and mobile jib 172 in secondary dead bolt external member is only made by embodiment is all round restriction, It is because limited block 173 and secondary dead bolt external member gabarit 620 is without being set as circle, and only need to meet aforesaid lateral cross-sectional area Condition.

A little variation can be made, as by pair dead bolt link rod 170 and secondary dead bolt external member 600 on the basis of above-described embodiment 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 the fixing assembling of slide block end face 182, specifically Being the lateral cross-sectional area lateral cross-sectional area more than mobile jib 172 of limited block 173, secondary dead bolt link rod contact part 171 is positioned at limit Position block 173, slide block contact part 181 is positioned at slide block end face 182, secondary dead bolt external member 600 and the fixing assembling of slide block end face 182, secondary lock The overall 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 Having space, this space is for the relatively secondary dead bolt external member 600 of mobile jib 172 and the mass activity of slide block 180.Compare enforcement Example, for both secondary dead bolt external member 600 and limited block 173 fix 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 Guan Bi, Present invention is primarily targeted at solution impact noise, the noise of aforementioned friction is then secondary.Secondary dead bolt external member 600 pole The form of end is when it fixes assembly relation, and form is several paster shapes, is fitted in the slide block contact part 181 of slide block 180 Or the secondary dead bolt link rod contact part 171 of secondary dead bolt link rod 170, also can play the effect of buffering collision of closed, but Comparatively speaking stress The most uniform.

The flexible structure of embodiment, it is also possible to be to combine kind of an embodiment, respectively at secondary dead bolt link rod contact part 171 and slide block Set up secondary dead bolt external member 600 on contact part 181, and be the relation of fixing assembling with them respectively.By two secondary dead bolt external members 600 can be substantially reduced noise, it may be said that be to be close to not have noise, but relative cost also considerably increases, and fills accordingly Join difficulty to be also significantly increased.
