Description

Quiet button box

Technical field

The utility model relates to building household door lock fittings, relates in particular to the quiet adjustable button box that noise is less.

Background technology

Door lock fittings used, makes with metal material conventionally at present, 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 people's the level of consumption, in office space or household occasion, all wish to reduce this type of noise as far as possible.There are many inventors to propose the disclosed a kind of low-resistance silent door lock of corresponding solution: CN203050243U from different technical standpoints, adopt at lock box front end the soft lock box roller of matter is installed, at button box front end, the soft button box guide card roller of matter is installed, the scheme of the soft button box shell fragment of matter is installed in button box, can slows down the parts friction such as dead bolt and lock box and button box at closing time or shock and the noise that sends.This scheme is from the most easily producing the dead bolt clashing into, directly slowing down the shock of dead bolt or improve around the parts that are in contact with it, and alleviating this one side of noise producing at closing time, has produced certain good effect.But such scheme is all to have reduced to a certain extent the noise producing at closing time.In fact; in door lock use procedure; under the shock many times of dead bolt, can there is friction or displacement in button box, fit clearance between dead bolt and button box is strengthened and produce loosening, and; because material difference and the weatherability difference of door body; also can make fit clearance between dead bolt and button box strengthen and produce loosening, once have loosening generation, in the time that door is shut; often can make door shake because of wind outdoors or indoor Air Flow, thereby produce noise between dead bolt and button box.

Summary of the invention

The purpose of this utility model is to solve door lock in use, between dead bolt and button box, because of the loosening problem making a noise, provides a kind of quiet button box.The technical scheme adopting is: between button box and buckle, establish the inner box of a position-adjustable, an inner box groove is established respectively at inner box two ends, and inner box groove one side is convexly equipped with a limited block, and a line position hole is established at inner box middle part, and an adjusting chamber is established in inner side, line position hole; A buckle fixing hole and a dead bolt hole are established respectively in buckle two ends, wherein dead bolt hole is corresponding with the inner box groove of being located at inner box, dead bolt hole one side is established respectively stopper slot engaging corresponding to the limited block of being located at inner box groove side, and it is corresponding with the line position hole at inner box middle part that an adjustment hole is established at buckle middle part; It is corresponding with buckle fixing hole fixing that a button box fixing hole is established respectively at button box two ends, and it is corresponding with the line position hole of inner box that button box center bottom is provided with an adjusting uropore; If an adjusting screw(rod), its middle part is provided with a square shaft, and front end is provided with regulating tank, tail end is provided with threaded post; If an eccentric wheel is placed in the adjusting chamber at inner box middle part, if a square hole runs through eccentric wheel one side, its side is provided with multipair standstill face, adjusting screw(rod) penetrates from adjustment hole, through behind line position hole, square shaft is inserted in square hole, the threaded column of its tail end is through regulating uropore to pass, and a cushion and a nut and this double-screw bolt spiral shell are solid.The utility model is by rotating adjusting screw(rod), its square shaft of nationality drives eccentric wheel, drive inner box to make lateral displacement, thereby regulate the gap between inner box groove and dead bolt, avoid making a noise because excesssive gap makes a body produce to rock, greatly improved the suitability of door lock, obviously extended the application life of door lock, and reached good muting function.
