Summary of the invention
Prior art is difficult to meet the needs of people, for the problem solving above-mentioned existence, the utility model proposes a kind of Novel sound-silencing lock body, quiet circle and muting pad isolation movable part mechanical activity that its employing wear-resistant plastic is made prevent from clashing into, startup chain bar also uses wear-resistant plastic, metal and plastics collision will not send sound.
For achieving the above object, this utility model following technical scheme of offer: a kind of Novel sound-silencing lock body, including cassette bottom assembly, the first dead bolt and the second dead bolt；Described cassette bottom assembly front end offers the first groove and the second groove matched with the first dead bolt and the second dead bolt, and the first dead bolt and the second dead bolt are fastened in the first groove and the second groove respectively；Described first dead bolt and the second dead bolt rear end are connected to noise reduction and stretch chain bar and tumbler, and noise reduction is stretched and is respectively arranged with the first quiet circle and the second quiet circle between chain bar and tumbler and cassette bottom assembly antetheca；Described noise reduction is stretched to be provided with between deck, and deck and the first quiet circle and cassette bottom assembly rear wall in the middle part of chain bar and is respectively arranged with return spring；Described cassette bottom assembly front has been opened in lockhole, and rotor is arranged in lockhole；Startup bearing it is provided with between described rotor and lockhole；It is provided with the first pole and the second pole on described rotor, and the first pole is fastened in deck；It is provided with journal stirrup on described tumbler, and journal stirrup is connected by bolt and the second pole；It is additionally provided with pillar on described tumbler, and startup chain bar is arranged on tumbler by pillar.
Further, described first dead bolt is additionally provided with muting pad.
Further, described cassette bottom assembly is further opened with several fixing hole.
Further, described first quiet circle, the second quiet circle, muting pad and startup chain bar respectively wear-resistant plastic are made.
Compared with prior art, the beneficial effects of the utility model are: this Novel sound-silencing lock body, quiet circle and muting pad isolation movable part mechanical activity that its employing wear-resistant plastic is made prevent from clashing into, and startup chain bar also uses wear-resistant plastic, metal and plastic drive and will not send sound；No matter opening the door or close the door all without producing noise, thus not affecting environment or the people in room of having a rest, substantially improving the noise pollution that in work and rest environment, lock body brings；Practical, it is easy to promote the use of.
