Description
Technical field
The present invention relates to five metals door lock fittings, especially the lock body part with damping.
Background technology
At present, market uses extensive lock body, for realizing noise reduction at closing time, takes multiple technologies scheme:
A kind of low-resistance silent door lock disclosed in cn203050243u, installs the soft lock box roller of matter using in lock box front end, before button box
The soft button box guide card roller of matter is installed at end, installs the scheme of the soft button box shell fragment of matter, can slow down dead bolt at closing time in button box
The noise sending with the part friction such as lock box and button box or shock；A kind of silent door lock disclosed in cn202530854u, adopts
Carry the scheme of a packing ring in dead bolt neck and slide block suit place, can make between dead bolt and slide block, not occurring relative motion to collide,
Thus not therefore making a noise；Cn202530855u discloses silent door lock, sets groove using dead bolt surface, and groove pastes
Close the scheme of quiet cushion rubber, the thickness of quiet cushion rubber is more than the depth of groove so as to surface is higher than the surface of dead bolt other parts,
Farthest avoid the frictional impact between metalwork, thus greatly reducing the noise that door lock brings.Above-mentioned patent literary composition
Offer, be all directly to slow down the shock of dead bolt from the dead bolt being also easy to produce shock most or changed around the part being in contact with it
Enter, mitigating this one side of the noise producing at closing time, creating certain effect.But, the dead bolt of such scheme resets all
It is that at closing time, under the resilience force of spring acts on, dead bolt quickly ejects, and strikes any hard using recoil of spring structure
Part all can send sound, and therefore, such scheme fails to fundamentally solve the problems, such as to produce at closing time noise.
Content of the invention
The purpose of the present invention is to reduce the collision sound that Door-lock bolt at closing time produces further, provides a kind of band to damp
Mute lock body, eliminates the sound colliding and sending with other parts because of dead bolt at closing time, has reached preferable muting function.
The technical solution used in the present invention is: be provided with a cassette bottom assembly, a latch bolt, a back-moving spring, an antivibrator, one group
Fructus Persicae；Cassette bottom assembly front end is provided with inclined tongue hole, middle part sets a fixed block, a guide groove and a slide block, rear portion are provided with an antivibrator positioning
Hole；It is provided with a guide hole 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
It is provided with capel；It is provided with a snap ring, rear portion is provided with a damper rod, damping boom end is provided with a location hook in the middle part of described antivibrator；
Described group of Fructus Persicae side is provided with dials knife；Described antivibrator front end build-in is in the capel of latch bolt rear end, middle part passes through located at fixed block
The antivibrator that the guide hole at middle part, the location hook of rear end embed located at back box module back positions in the hole；Described back-moving spring is embedded in
Outside antivibrator, press between latch bolt and fixed block；Described slide block is fastened in the snap ring in the middle part of antivibrator, and the cunning of its side
Tenon snaps in guide groove；Dialling of described group of Fructus Persicae side stirs slide block along the movement of chute direction in front of the pluggable slide block of knife.
Antivibrator of the present invention is linear radial antivibrator, by such scheme, rotates group Fructus Persicae and can drive latch bolt
It is moved rearwards by, now, the antivibrator non-resistance in latch bolt rear end acts on；When dialling Fructus Persicae return, latch bolt is in action of reset spring power
Lower forward movement, antivibrator plays a cushioned resistance effect, it is to avoid latch bolt is returned to rapidly start stop bit under spring force
Put.The present invention takes this to achieve latch bolt and resets slow and stable function, has reached the strike note reducing the closing of lockset latch bolt
Sound, reduces the technique effect that door lock uses noise further.

Specific embodiment
The present invention can be implemented in the following way:
As shown in figure 1, the present invention is provided with a cassette bottom assembly 1, a latch bolt 2, a back-moving spring 3, an antivibrator 4 and one group of Fructus Persicae
5；Cassette bottom assembly 1 front end is provided with inclined tongue hole 11, and middle part sets a fixed block 12, a guide groove 13 and a slide block 14, and rear portion is provided with a resistance
Buddhist nun's device location hole 15；It is provided with a guide hole 121 in the middle part of described fixed block 12, be provided with a draw-in groove 141 in the middle part of described slide block 14, side sets
There is sliding tenon 142；Latch bolt 2 rear end is provided with capel 21；It is provided with a snap ring 41, rear portion is provided with a damper rod 42, damping in the middle part of antivibrator 4
Bar 42 end is provided with a location hook 421；Dial Fructus Persicae 5 side and be provided with group knife 51.Described slide block 14 can be fastened in antivibrator 4 middle part
In snap ring 41, and the sliding tenon 142 of its side can snap in guide groove 13.
As shown in Fig. 2 antivibrator 4 of the present invention is linear radial antivibrator, its front end build-in is embedding in latch bolt 2 rear end
In ring 21, middle part is arranged in fixed block 12, the location hook 421 of rear end embeds the antivibrator positioning located at back box assembly 1 rear portion
In hole 15；Back-moving spring 3 is embedded in outside antivibrator 4, presses between capel 21 and the fixed block 12 of latch bolt 2 rear end；Dial Fructus Persicae 5 side
Knife 51 of dialling can be inserted in front of slide block 14, rotate and dial Fructus Persicae 5 and can stir slide block 14 and be moved rearwards by along chute 13 direction, thus driving
In dead bolt 2 retraction cassette bottom assembly 1.In the process, damper rod 42 retracts in antivibrator 4, and non-resistance effect.
As shown in figure 3, when dialling Fructus Persicae 5 return, latch bolt 2 moves forward under back-moving spring 3 active force, damper rod 42 rear end
As fixing end, damper rod 42 front end is drawn out from antivibrator 4, at this time, it may be necessary to overcome the cushioned resistance of antivibrator, therefore,
Latch bolt 2 can be avoided to be returned to rapidly start-stop position under the resilience force effect of spring 3.The present invention takes this to achieve latch bolt 2 and resets
Slow and stable function, has reached the shock sound reducing lockset latch bolt 2 closing, reduces door lock further and uses noise
Technique effect.
