Abstract
The invention discloses a door lock with a silencing effect, comprising a locking box, wherein the locking box is internally provided with a transmission mechanism and a locking tongue capable of doing axial and telescopic movement; the transmission mechanism comprises a sliding block; one side of the sliding block is provided with a sliding block spring; and one end of the sliding block spring is fixedly arranged on the sliding block by a second sliding block rubber pad, and the other end of the sliding block spring extends out of the sliding block, and the extending line is intersected with a fixed part in the locking box. The door lock disclosed by the invention has the advantages that on one hand, by use of cushioning parts such as the spring, the moving speed of the transmission mechanism is reduced; and on the other hand, since a great amount of nonmetallic silencing materials such as rubber rings and rubber pads are used, the friction and the collision among metal parts are furthest avoided, so that the noise caused by the door lock is greatly reduced.
Description
Technical field
The invention belongs to household five metals technical field, particularly relate to door lock, the door lock with muting function that especially noise is less.
Background technology
Door lock is that its basic structure comprises a dead bolt that can carry out under external force stretching motion, matches with the button box being contained on doorframe in order to keep space privacy to be arranged on a kind of hardware on door, can prevent from being opened by fortuitous events such as winds.
In some special occasions, as ward etc., very high to the requirement that environment is quiet, the sound that switch gate produces is enough to become noise source; For the noise of door and doorframe collision generation, people have found out many solutions, as adopted damp hinge, and at door and doorframe junction, adhesive tape etc. are set.After this problem solves, the sound that door lock sends at closing time just seems considerably loud, makes us irritated.
Summary of the invention
The object of the invention is to solve the noise problem that door lock sends in switching process, the door lock that a kind of sound is lighter is provided.
Applicant is by careful research discovery, and the noise that door lock sends is mainly from following action: the collision of button box panel on dead bolt and doorframe; Dead bolt is compressed motion, with the collision of other transmission mechanisms in lock box; Dead bolt is released after entering button box, to the shock of button box; When artificial driving dead bolt, the frictional impact between transmission mechanism.The wherein sound maximum thirdly to send especially.
Based on above analysis, the technical scheme that the present invention proposes is such: the door lock with muting function, comprise lock box, in lock box, be provided with transmission mechanism and can make the dead bolt that axial stretching moves, it is characterized in that: described transmission mechanism comprises a slide block and a shifting block, shifting block is installed in lock box, can rotate as pivot under external force; Dead bolt rear portion is with dead bolt neck, one end of slide block and dead bolt neck fit, and suit place is with a packing ring, and the other end of slide block is provided with a through hole, and the moving tooth of shifting block snaps in this through hole, and engaging place is with a cushion block; In lock box, be fixed with a divider wall with U v notch v, dead bolt and dead bolt neck main body are in divider wall front side, and slider body is in divider wall rear side, and both fit positions are through the U v notch v of divider wall; Dead bolt neck overcoat has latch bolt spring, and one end props up dead bolt, and the other end props up divider wall antetheca; In lock box, there is a pair of the first slide block rubber cushion, be divided into the upper and lower of slide block; Slide block both sides are respectively arranged with sliding block spring and shifting block spring, and shifting block spring one end props up divider wall rear wall, and the other end and shifting block are inconsistent; Sliding block spring one end is by the second slide block elastic mounting on slide block, and the other end stretches out outside slide block, and its extension line is crossing with divider wall rear wall, and intersection is provided with one the 3rd slide block rubber cushion.
On slide block of the present invention, with sliding block spring, in the time of slide block movement, can directly not bump against the fixed part in lock box like this, but be cushioned with sliding block spring; The 3rd slide block rubber cushion is set in intersection, can further cushions and absorb noise.
In the present invention taking the direction that connects lock box and button box for axially, stretch out the direction of lock box taking dead bolt as front, taking its opposite direction as after.
After the present invention installs, under free state, latch bolt spring opens, and dead bolt is stretched out outside lock box.When at closing time, dead bolt is subject to the compressing indentation backward of button box on doorframe, and latch bolt spring is also compressed, and slide block is motion backward simultaneously also; Work as door-closing in-place, dead bolt enters after button box completely, and latch bolt spring discharges, dead bolt is ejected, and slide block also travels forward simultaneously, in motion process its with sliding block spring can encounter the 3rd slide block rubber cushion of divider wall rear wall, thereby play cushioning effect, reduce the movement velocity of slide block and dead bolt; Slide block and dead bolt move forward, and dead bolt can be encountered button box inwall, and because there is outstanding quiet cushion rubber on dead bolt surface, first it will touch button box, further play the effect of buffering and noise reduction.In the time using handle to open the door, rotate shifting block by handle, moving tooth pulls slide block and dead bolt to move backward, makes in dead bolt retraction lock box; Shifting block spring is compressed simultaneously, and shifting block is formed to buffering, makes the movement velocity of shifting block and slide block, dead bolt be unlikely to too fast; When decontroling handle, when dead bolt ejects, course of action and noted earlier basically identical.
From above analysis, one aspect of the present invention, by using the bolsters such as spring, has reduced the movement velocity of transmission mechanism; Use in a large number on the other hand the nonmetallic quieter material such as cushion rubber, rubber cushion, farthest avoided the frictional impact between metalwork, thereby greatly reduced the noise that door lock brings.
