The front end of the box bottom assembly is provided with an inclined lock dog hole in the front end, provided with a fixing block, a guide groove and a sliding block in the middle and provided with a damper positioning hole in the rear; the rear end of the damper is provided with a capel; the damper is provided with a clamping ring in the middle and provided with a damping rod in the rear, and the end of the damping rod is provided with a positioning hook; the front end of the damper is fixedly embedded in the capel at the rear end of the inclined lock dog, the middle of the damper penetrates through a guide hole in the middle of the fixing block, and the positioning hook at the rear end of the damper is embedded into the damper positioning hole in the rear of the box bottom assembly; the damper is a wire diameter damper, the inclined lock dog can be driven to move backwards without resistance by rotating the poking peach, and the poking peach needs to overcome buffering resistance of the damper to return, so that it is avoided that the inclined lock dog rapidly returns to the start-stop position under the action of the spring.
Description
Technical field
The present invention relates to five metals door lock fittings, especially the lock body parts with damping.
Background technology
At present, on market, use lock body widely, for realizing noise reduction at closing time, take the disclosed a kind of low-resistance silent door lock of multiple technologies scheme: CN203050243U, adopt at lock box front end the soft lock box roller of matter is installed, at button box front end, matter soft button box guide card roller is installed, the scheme that the soft button box shell fragment of matter is installed in button box, can slow down the parts friction such as dead bolt and lock box and button box at closing time or shock and the noise that sends; The disclosed a kind of silent door lock of CN202530854U, adopts the scheme with a packing ring in dead bolt neck and slide block suit place, can make not occur between dead bolt and slide block relative motion collision, thereby can therefore not make a noise; CN202530855U discloses silent door lock, adopt dead bolt surface to establish groove, the fit scheme of quiet cushion rubber of groove, the thickness of quiet cushion rubber is greater than the degree of depth of groove, make the surface of its surface higher than other parts of dead bolt, farthest avoid the frictional impact between metalwork, thereby greatly reduced the noise that door lock brings.Above-mentioned patent documentation, is all 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 effect.But it is all to adopt recoil of spring structure that the dead bolt of such scheme resets, at closing time, under the screen resilience effect of spring, dead bolt ejects fast, strikes any hard part and all can sound, therefore, such scheme all could not fundamentally solve the problem that produces at closing time noise.
Summary of the invention
The object of the invention is further to reduce the collision sound that Door-lock bolt at closing time produces, a kind of mute lock body with damping is provided, eliminated at closing time because dead bolt and other parts collide the sound sending, reached good muting function.
The technical solution used in the present invention is: be provided with a box bottom component, a latch bolt, a back-moving spring, a damper, one group of peach; Box bottom component front end is provided with inclined tongue hole, middle part is established a fixed block, a guide groove and a slide block, rear portion and is provided with a damper locating hole; Described fixed block middle part is provided with a guide hole, and described slide block middle part is provided with a draw-in groove, side is provided with sliding tenon; Described latch bolt rear end is provided with capel; Described damper middle part is provided with a snap ring, rear portion is provided with a damper rod, and damper rod end is provided with a location hook; Described group of peach one side is provided with dials cutter; Described damper front end build-in in the capel of latch bolt rear end, middle part embeds and is located in the damper locating hole at case assembly rear portion, the end through the location hook of guide hole, rear end of being located at fixed block middle part; Described back-moving spring is embedded in outside damper, presses between latch bolt and fixed block; Described slide block is fastened in the snap ring at damper middle part, and the sliding tenon of its side snaps in guide groove; The dialling cutter and can insert slide block front and stir slide block and move along chute direction of described group of peach one side.
Damper of the present invention is wire diameter damper, by such scheme, rotates group peach and can drive latch bolt to move backward, now, in the damper non-resistance effect of latch bolt rear end; In the time dialling peach return, latch bolt moves forward under action of reset spring power, and damper plays a buffering drag effect, avoids latch bolt under spring-force driven dual, to be returned to rapidly start-stop position.The present invention takes this to have realized the latch bolt slowly and stably function that resets, and has reached and has reduced the shock sound that lockset latch bolt is closed, and further reduces door lock and use the technique effect of noise.

The specific embodiment
The present invention can implement in the following way:
As shown in Figure 1, the present invention is provided with a box bottom component 1, a latch bolt 2, a back-moving spring 3, a damper 4 and one group of peach 5; Box bottom component 1 front end is provided with inclined tongue hole 11, and a fixed block 12, a guide groove 13 and a slide block 14 are established in middle part, and rear portion is provided with a damper locating hole 15; Described fixed block 12 middle parts are provided with a guide hole 121, and described slide block 14 middle parts are provided with a draw-in groove 141, side is provided with sliding tenon 142; Latch bolt 2 rear ends are provided with capel 21; Damper 4 middle parts are provided with a snap ring 41, rear portion is provided with a damper rod 42, and damper rod 42 ends are provided with a location hook 421; Dial peach 5 one sides and be provided with group cutter 51.Described slide block 14 can be fastened in the snap ring 41 at damper 4 middle parts, and the sliding tenon 142 of its side can snap in guide groove 13.
As shown in Figure 2, damper 4 of the present invention is wire diameter damper, its front end build-in in the capel 21 of latch bolt 2 rear ends, middle part is arranged in fixed block 12, the location hook of rear end 421 embeds and is located in the damper locating hole 15 at end case assembly 1 rear portion; Back-moving spring 3 is embedded in outside damper 4, presses between the capel 21 and fixed block 12 of latch bolt 2 rear ends; Group cutter 51 of dialling peach 5 one sides can insert slide block 14 fronts, and rotation group peach 5 can stir slide block 14 and move backward along chute 13 directions, thereby drives in dead bolt 2 retraction box bottom components 1.In this process, damper rod 42 retracts in damper 4, and non-resistance effect.
As shown in Figure 3, in the time dialling peach 5 return, latch bolt 2 moves forward under back-moving spring 3 active forces, damper rod 42 rear ends are as fixed end, damper rod 42 front ends are drawn out from damper 4, now, need to overcome the buffering resistance of damper, therefore, can avoid latch bolt 2 to be returned to rapidly start-stop position under the screen resilience effect of spring 3.The present invention takes this to have realized that latch bolt 2 resets slowly and function stably, has reached and has reduced the shock sound that lockset latch bolt 2 is closed, and further reduces door lock and use the technique effect of noise.
