Description
Technical field
The utility model relates to a kind of five metals door lock fittings, especially the lock body parts of magnetic door lock.
Background technology
At present, magnetic force lock body market extensively used is all utilize magnetic force swing arm that is attracting or the promotion magnetic force dead bolt that repels each other to reach showing of dead bolt.Namely CN2916042Y discloses a kind of magnetic key operated lock, comprise lock body and latch plate composition, wherein said lock body is built-in with bolt component and assembly of unblanking, described latch plate composition includes buckle magnet steel, described bolt component includes dead bolt magnet steel, and between described buckle magnet steel and described dead bolt magnet steel, heteropole is attracting.Under magneticaction, there is certain speed and acceleration in fork and dead bolt, when fork stops, must having the mutual collision of mechanical part, cause ear-piercing noise; And shuttle-type magnetic force dead bolt, when showing dead bolt top and bottom exist linear velocity difference and after causing dead bolt to be shown completely upper and lower side extension elongation inconsistent, make dead bolt seem crooked, lose its aesthetic appearance.In addition, at present for conventional door back gauge specification 50mm, 55mm, 60mm, 65mm, adopt different lock body specifications respectively, adopt the component of different size to produce, material kind is more, and management cost is higher.
Summary of the invention
The utility model provides a kind of quiet magnetic force lock body, its objective is the noise and deficiency in shape that improve existing product, reduces door lock and uses noise, makes that door lock opening and closing are more quiet, feel is better; Dead bolt is optimized, makes it more attractive in appearance; In addition, for the door back gauge lock body being used in different size, realize single component multiple use, reduce material quantity, reduce management cost.
The technical scheme that the utility model adopts is: establish a lock case bottom component, side's tongue assembly, a handle to dial peach and a button box assembly; Lock case bottom component comprises at the bottom of a liner plate, a box, and liner plate is provided with square bolt hole, the front portion side of being provided with tongue guide groove at the bottom of box, spacing salient point on rear side of side's tongue guide groove, be provided with noise reduction stud in the middle part of at the bottom of box and put a noise reduction gum cover, rear portion at the bottom of box is provided with pull bar gathering sill, is provided with buffering foam on rear side of at the bottom of box; Side's tongue assembly comprises side's tongue overcoat, side's tongue, side's tongue magnet, a pull bar, a fairlead, a back-moving spring and an E type jump ring; Side's tongue overcoat side is provided with buckles block by outside the square tongue outer hitch side of being fixed in tongue; Tongue front end, the tongue magnet side of embedding, side, outside the square tongue overcoat side of being placed on tongue, tongue rear end, the pull bar side of being located at; Fairlead and back-moving spring are located on pull bar, and fairlead side is provided with guide pad and snaps in the pull bar gathering sill at rear portion at the bottom of box, and fairlead central authorities are provided with through hole so that slide on pull bar; Back-moving spring presses between E type jump ring and fairlead; Pull bar rear portion is provided with several draw-in groove, E type jump ring can be selected to snap onto in corresponding draw-in groove according to adaptive lock body specification; Handle dials that peach one end is provided with sliding piece, the other end is provided with banking stop, and middle part is provided with anti-rotation block, and sliding piece and fairlead compress, and banking stop and anti-rotation block are stuck in noise reduction stud both sides; When external force clockwise direction rotation handle dials peach, sliding piece is stirred fairlead backward and is exerted pressure to back-moving spring, until the banking stop of the other end and the noise reduction gum cover be enclosed within noise reduction stud compress; After external force is cancelled, fairlead pushes away forward by the elastic-restoring force of back-moving spring, until anti-rotation block and noise reduction gum cover compress; Button box assembly is made up of a buckle, a button box and a button box magnet, and button box magnet is fastened in button box, attracting with square tongue magnet heteropole.
When being in free state, anti-rotation block and noise reduction gum cover compress and are fixed in the middle part of pull bar by fairlead, and under the elastic force effect of back-moving spring, magnetic force side's tongue is withdrawn at the bottom of box inner by the E type jump ring at pull bar rear portion, and can not freely stretch out outside at the bottom of box, when being in locking condition, lock case bottom component aligns with button box component level, square tongue magnet in side's tongue and the button box magnet in button box assembly are in heteropole attracting state, at attracting magneticaction, side's tongue starts to button box horizontal movement, in side's tongue motion process, two blocks of magnet more and more closely cause and drive magnetic force to strengthen gradually, E type jump ring moves with square tongue and also makes back-moving spring compression more and more, reseting elasticity increases gradually, in this motion process, drive that magnetic force is always faint is greater than reseting elasticity, the side's of driving tongue buckles in button box and achieves locking, and in turn ensure that the acceleration of square tongue in whole motion process and speed are unlikely to excessive and the side's of causing tongue stops after stretching out completely suddenly time and button box cause mechanical collision to produce noise, reach muting function during locking, when using handle to unblank, handle is dialled peach clockwise direction and is rotated, sliding piece promotes fairlead backward, fairlead pressed home spring increases reseting elasticity, when reseting elasticity is greater than driving magnetic force, side's tongue starts retraction in lock case bottom component until be pulled lock case bottom component inside completely, now, the banking stop that handle dials the peach other end compresses with the noise reduction gum cover be enclosed within noise reduction stud, ward off and exempt from noise generation, meanwhile, pull bar tail end contacts with buffering foam and plays buffering effect, the collision of the side's of slow down tongue and spacing salient point, wards off and exempts from noise generation.
The utility model, by such scheme, reaches good muting function, improves lock body and uses feel; Dead bolt directly stretch into, without crooked phenomenon, fashion attractive in appearance; Magnetic force side's tongue achieves the multi-purpose design optimization of single component, decreases material quantity, reduces management cost.
