Abstract
The utility model relates to an anti-collision silent door lock. The door lock comprises a door sheet installation part and a door frame installation part and is characterized in that the door sheet installation part and the door frame installation part are respectively an E-shaped permanent magnet; and the poles of the corresponding positions of the two magnets are opposite. In a door closing process, when the door sheet installation part approaches the door frame installation part, due to variation of the relative positions, the door is successively subjected to the gravity, repulsion and re-gravity and is finally in a closed state. In the whole closing process, a door sheet and a door frame are not in direct contact, thus achieving all-process silence. Meanwhile, in the door closing process, the door is subjected to repulsion before being completely closed, thus the aim of anti-collision can be achieved. The door can be opened by pulling or pushing forcibly. The silent door lock is very suitable for places such as various doors or baby rooms in families, hospitals, kindergartens and the like without anti-theft problems.
Description
Technical field
The utility model relates to a kind of door lock, particularly a kind of crashproof silent door lock.
Background technology
At present, at the door of family and office, door lock is installed all, plays the effect of safety, sound insulation, protection privacy.At some special occasions, such as infant room, hospital or the late into the night, conventional door lock opens or closes in process at door, all can produce noise to a certain degree, makes troubles to life.
Chinese patent 201110404982.7,201210143801.4,201010300841.6 grades disclose the design scheme of some silent door locks, have reduced to a certain extent door noise in use.Although above Patent design has all to a certain degree reduced noise, with existing Mechanical Contact in process, can not fundamentally solve noise problem.
Summary of the invention
For the problem of present existence, the utility model provides a kind of non-contact type crashproof silent door lock.
The crashproof silent door lock of the utility model design comprises door-plate installed part and doorframe installed part, and it is characterized in that: door-plate installed part and doorframe installed part are respectively E shape permanent magnet, and 2 groups of magnet correspondence position magnetic poles are opposite.
In the process of closing the door, when door-plate installed part and doorframe installed part near the time, due to the variation of relative position, successively be subject to gravitation, repulsion, then the effect of gravitation, finally make door be in closed condition.In whole closing process, door-plate without directly contacting, is realized omnidistance quiet with doorframe.Simultaneously, due in the process of closing the door, before the complete closure of door, be subject to the repulsion effect, therefore can play crashproof purpose.In the time of need to opening the door, only need pull at or push away, door can be opened.This utility model silent door lock is highly suitable for not existing the occasions such as the various doors of household internal of antitheft problem or infant room, hospital, kindergarten.
Compared with prior art, the utlity model has following significant advantage is:
1, door lock is to realize by magnetic attraction on function, has therefore eliminated the noise that conventional door lock produces in the Mechanical Contact process fully.
2, unique magnetic Circuit Design can be avoided the shock that may exist at closing time, and is practical.
Description of drawings
Fig. 1 is the position view of crashproof silent door lock.
Fig. 2 is the plan structure schematic diagram of door-plate and doorframe installed part magnet part.
Fig. 3 is door door-plate and doorframe installed part magnetic circuit distribution schematic diagram when not closed.
Door-plate and a doorframe installed part magnetic circuit distribution schematic diagram when Fig. 4 is closed.
Wherein door-plate installed part 1, doorframe installed part 2, door-plate 3, doorframe 4 and the magnetic line of force 5.
The specific embodiment
By the following examples technical solutions of the utility model are described further.
Crashproof silent door lock comprises door-plate installed part and doorframe installed part, it is characterized in that: door-plate installed part 1 and doorframe installed part 2 are respectively E shape permanent magnet, and 2 groups of magnet correspondence position magnetic poles are opposite.
In the process of closing the door, when door-plate installed part 1 and doorframe installed part 2 are close, due to the variation of relative position, successively be subject to gravitation, repulsion, then the effect of gravitation, finally make door be in closed condition.In whole closing process, door-plate 3 without directly contacting, is realized omnidistance quiet with doorframe 4.Simultaneously, due in the process of closing the door, before the complete closure of door, be subject to the repulsion effect, therefore can play crashproof purpose.In the time of need to opening the door, only need pull at or push away, door can be opened.This utility model silent door lock is highly suitable for not existing the occasions such as the various doors of household internal of antitheft problem or infant room, hospital, kindergarten.
