Description

Quiet button box

Technical field

The present invention relates to building household door lock fittings, particularly relate to the quiet adjustable button box that noise is less。

Background technology

Presently used door lock fittings, makes typically by metal material, is opening the door and at closing time, because of the shock between each parts or friction, all can make a noise。Along with the raising of the level of consumption of people, in office space or residential applications, it is intended to reduce this type of noise as far as possible。Many inventors have been had to propose corresponding solution from different technical standpoints: the disclosed a kind of low-resistance silent door lock of CN203050243U, adopt and the lock box roller that matter is soft is installed in lock box front end, the button box guide card roller that matter is soft is installed in button box front end, the scheme of the soft button box shell fragment of matter is installed in button box, it is possible to slow down dead bolt and the parts friction such as lock box and button box or shock at closing time and the noise that sends。The program is from the dead bolt being easily generated most shock, directly slows down clashing into or improving around the parts being in contact with it of dead bolt, alleviating this one side of noise produced at closing time, creates certain good effect。But, such scheme is all reduce the noise produced at closing time to a certain extent。Actually; in door lock use procedure; can there is friction or displacement in button box, make the fit clearance between dead bolt and button box strengthen and produce to loosen under the shock many times of dead bolt, and; because the material difference of door body and weatherability difference; also the fit clearance between dead bolt and button box being made to strengthen and produce to loosen, loosening generation once have, when door is finally closed; often door is made to shake because of the air flowing of wind outdoors or indoor, thus producing noise between dead bolt and button box。

Summary of the invention

Present invention aim to address that door lock is in use, the problem made a noise between dead bolt and button box, it is provided that a kind of quiet button box because loosening。The technical scheme adopted is: set the inner box of a position-adjustable between button box and buckle, and inner box two ends set an inner box groove, inner box groove side projection one limited block respectively, set a line position hole, set an adjustment chamber inside line position hole in the middle part of inner box；Buckle two ends set a buckle fixing hole and a dead bolt hole respectively, wherein dead bolt hole is corresponding with the inner box groove being located at inner box, engaging corresponding to the limited block being located at inner box groove side that dead bolt hole side sets a stopper slot respectively, sets an adjustment hole corresponding with the line position hole in the middle part of inner box in the middle part of buckle；Button box two ends set that a button box fixing hole is corresponding with buckle fixing hole to be fixed respectively, and it is corresponding with the line position hole of inner box that button box center bottom is provided with an adjustment uropore；If an adjusting screw rod, being provided with a square shaft in the middle part of it, front end is provided with regulating tank, tail end is provided with threaded post；If an eccentric is placed in the adjustment intracavity in the middle part of inner box, if a square hole runs through eccentric side, its side is provided with multipair standstill face, adjusting screw rod penetrates from adjustment hole, behind line position hole, square shaft is inserted in square hole, the threaded post of its tail end is adjusted uropore and passes, and a cushion and a nut are solid with this stud spiral shell。The present invention is by rotating adjusting screw rod, its square shaft of nationality drives eccentric, inner box is driven to make lateral displacement, thus the gap regulated between inner box groove and dead bolt, avoid and make because of excesssive gap door body produce to rock to make a noise, drastically increasing the suitability of door lock, the service life of door lock is obviously prolonged, and has reached good muting function。

Detailed description of the invention

As shown in Figure 1: the present invention sets the inner box 2 of a position-adjustable between button box 1 and buckle 3, inner box 2 two ends set an inner box groove 21, inner box groove 21 side projection one limited block 211 respectively, set a line position hole 22 in the middle part of inner box 2；Buckle 3 two ends set buckle fixing hole 32 and a dead bolt hole 31 respectively, wherein dead bolt hole 31 is corresponding with the inner box groove 21 being located at inner box 2, engaging corresponding to the limited block 211 being located at inner box groove 21 side that dead bolt hole 31 side sets a stopper slot 311 respectively, sets an adjustment hole 33 corresponding with the line position hole 221 in the middle part of inner box 2 in the middle part of buckle 3；It is corresponding with buckle fixing hole 32 fixing that button box 1 two ends set a button box fixing hole 11 respectively, and it is corresponding with the line position hole 22 of inner box 2 that button box 1 center bottom is provided with an adjustment uropore 12；If an adjusting screw rod 4, being provided with a square shaft 40 in the middle part of it, tail end is provided with stud 401, and front end is provided with regulating tank 402；If an eccentric 41 sets a square hole 411 runs through eccentric 41 side, its side is provided with multipair standstill face 412。

As shown in Figure 2: the dead bolt hole 31 at buckle 3 two ends of the present invention is corresponding respectively with inner box groove 21, stopper slot 311 engaging corresponding to limited block 211。

As shown in Figure 3, Figure 4: inside line position hole 22 of the present invention, set an adjustment chamber 23, eccentric 41 is placed in adjustment chamber 23；Adjusting screw rod 4 penetrates from adjustment hole 33, is inserted by square shaft 40 in the square hole 411 of eccentric 41 behind line position hole 22, and the threaded post 401 of its tail end is adjusted uropore 12 and passes, and a cushion 42 and a nut 43 are solid with this threaded post 401 spiral shell。

As shown in Figure 5: the present invention is by rotating adjusting screw rod, its square shaft 40 of nationality drives eccentric 41 to rotate, behind standstill face 412 and adjustment chamber 23 contact internal walls, inner box 2 can being driven to make lateral displacement, stopper slot 311 engaging corresponding to limited block 211 can ensure that the stationarity that inner box 2 moves。Translation by inner box 2, i.e. gap between scalable inner box groove 21 and dead bolt, it is to avoid make because of excesssive gap door body produce to rock to make a noise, drastically increase the suitability of door lock, the service life of door lock is obviously prolonged, and has reached good muting function。
