Description
Technical field
The utility model relates to a kind of door lock, is specifically related to a kind of silent door lock with buffer.
Background technology
Door lock of a great variety, all can produce noise usually in use.But, along with the pursuit of people to quality of the life is more and more higher, also more and more higher to the instructions for use of door lock, when needing especially to eliminate door interlock switch, the noise produced.Such as, application number: the patent of invention of 201410150578.5, disclose a kind of mute lock body with damping, be provided with a box bottom component (D1), a latch bolt (D2), one back-moving spring (D3), one damper (D4), one group of peach (D5), described box bottom component front end is provided with inclined tongue hole, a fixed block (D12), a guide groove (D13) and a slide block (D14) are established in middle part, and rear portion is provided with a damper locating hole (D15); A guide hole is provided with in the middle part of described fixed block; Be provided with a draw-in groove in the middle part of described slide block, side is provided with sliding tenon; Described latch bolt rear end is provided with capel (D21); Be provided with a snap ring in the middle part of described damper, rear portion is provided with a damper rod (D42), damper rod end is provided with a location hook (D421); Described slide block is fastened in the snap ring in the middle part of damper, and the sliding tenon of its side snaps in guide groove; Described damper front end build-in in the capel of latch bolt rear end, middle part be arranged in the middle part of fixed block guide hole in, the location hook of rear end embeds and is located in the damper locating hole at case assembly rear portion, the end; Described back-moving spring is embedded in outside damper, between the capel pressing on latch bolt rear end and fixed block.
Mute lock body with damping in above-mentioned prior art, its advantage is: when dialling peach return, latch bolt moves forward under action of reset spring power, damper plays a cushioned resistance effect, latch bolt is avoided to be returned to rapidly start-stop position under spring force, take this to achieve latch bolt to reset slowly and stable function, reach the shock sound reducing lockset latch bolt and close, reduce the technique effect that door lock uses noise; But, its shortcoming is: group peach of this mute lock body inside, to move after latch bolt or in reseting procedure, still produce noise because colliding with slide block and other positioning elements, simultaneously because the processing cost of damper is higher, installing and using precision higher, and easily there is stuck situation in Long-Time Service, thus causing the processing cost of this mute lock body higher, installation accuracy is higher, and job stability is poor.
Summary of the invention
The purpose of this utility model to solve above-mentioned the problems of the prior art, provides a kind of processing cost lower, and installation accuracy requires lower, good operating stability, and the better silent door lock of muting function.
For achieving the above object, the technical scheme that adopts of the utility model is as follows:
A kind of silent door lock, comprise lock housing, dead bolt, drive link, locating piece, spring and turning arm, described dead bolt is fixed in one end of drive link, described drive link transverse splicing is in locating piece, and can relative to locating piece transverse shifting, drive link is located at by described spring housing, its two ends contact with locating piece with dead bolt respectively, described turning arm is movably connected on the inwall of lock housing, described turning arm top is provided with slide block, it is characterized in that: described turning arm bottom is provided with limited block, described lock housing is provided with left positioning elastic element in the limited block contact position near right side wall and turning arm.
The material of described left positioning elastic element is rubber.
Described drive link is provided with snubber elastomeric element at the slide block contact jaw with turning arm.
The material of described snubber elastomeric element is rubber, and described snubber elastomeric element housing is located at drive link, and described snubber elastomeric element-external is also arranged with fixed cover.
Described lock housing is being provided with right positioning elastic element with left positioning elastic element corresponding height place.
The material of described right positioning elastic element is rubber, and described right positioning elastic element is circular.
Compared with prior art, the utility model has the advantage of: the utility model is by being provided with limited block in turning arm bottom, simultaneously, lock housing is provided with the left positioning elastic element of quality of rubber materials in the limited block contact position near right side wall and turning arm, thus play cushioning effect when dead bolt resets, eliminate the noise between dead bolt and door body, and this kind of structure processing cost is lower, installation accuracy requires lower, good operating stability; In addition, the snubber elastomeric element of the drive link end of being made up of rubber and the right positioning elastic element of lock-shell lining, avoid and produce noise with turning arm because colliding, thus make the muting function of this silent door lock better.
