Abstract
The utility model relates to an automatic magnetic lock. The automatic magnetic lock comprises a lock body and a panel, a main lock bolt, a main lock bolt support plate, a main lock bolt opening mechanism, a main lock bolt opening state fastening bit and a main lock bolt tension spring are arranged in the lock body, a magnetic component is movably arranged in the lock body and close to the panel, a magnet is fixedly arranged on an area, corresponding to the magnetic component, of a door frame, and polarity of opposite sides of the magnetic component and the magnet is identical or opposite. When the magnetic component gets close to the magnet, the magnetic component moves by means of the principle of mutual repulsion of same polarity and mutual attraction of different polarities, and the main lock bolt opening state can be triggered to open by the motion of the magnetic component. In the above structure, the magnetic component is mounted in the lock body, triggering is completed in the lock body by means of the principle of mutual repulsion of same polarity and mutual attraction of different polarities without protruding the panel of the lock body to touch the door frame, so that matching gap requirements between a door leaf and the door frame are not high since the gap is suitable for allowing the door leaf to enter the door frame only, and external paint of the door frame cannot be scraped.
Description
Technical field:
The utility model relates to door latch structure, especially a kind of magnetic automatic locking.
Background technology:
Automatic locking be because can automatically locking at closing time, thereby easy to use, obtains customer's generally favor.At present, automatic locking on the market is of a great variety, but structural principle is roughly the same, basically all adopt the touch-type structure, for example at master latch one contact is set, this contact outer end protrudes from lock panel, the inner links to each other with the master latch screens by toggle mechanism, when locking a door, according to contact and touching of doorframe and drive toggle mechanism and open the master latch screens, make the overhanging locking of master latch.The shortcoming of this structure is that the fit clearance between door leaf and the doorframe is had relatively high expectations, if fit clearance is excessive, then contact touches less than doorframe, can't touch the master latch screens realizes locking a door, if fit clearance is too small, then contact can be blocked by doorframe again, can't touch equally the master latch screens and realize locking a door.In addition, the contact in this structure also can cause scratch to the outer lacquer of doorframe, affects attractive in appearance.
The utility model content:
The purpose of this utility model is to overcome the deficiency of above-mentioned prior art, provides a kind of less demanding to the fit clearance between door leaf and the doorframe, and can not cause to the outer lacquer of doorframe the magnetic automatic locking of scratch.
The purpose of this utility model is achieved through the following technical solutions:
A kind of magnetic automatic locking comprises lock body and panel, is provided with master latch, master latch supporting plate, master latch opening mechanism, the screens of master latch opening, master latch extension spring in the lock body.In lock body, near the activity of panel place one magnetic element is set, on doorframe, zone that should magnetic element is fixedly installed a magnet, described magnetic element is identical or opposite with the polarity of magnet forward surface, when the close magnet of magnetic element, utilize the two two like magnetic poles repel each other or the principle that there is a natural attraction between the sexes that magnetic element is moved, the screens of described master latch opening is triggered according to the motion of magnetic element and opens.
Described magnetic element and magnet can be magnet or magnet steel.
Described magnetic element is identical with the polarity of magnet forward surface, described master latch opening screens one end rotates and arranges, the other end cooperates with draw-in groove clamping on being arranged on master latch, described magnetic element and the free end of a driving lever are supported and are connected or are fixedly connected with, the other end of described driving lever rotates to arrange and support with the joint end of master latch opening screens and cooperates, and is provided with the driving lever extension spring on the described driving lever.
Described master latch opening mechanism comprises lock core shifting block and revolving fragment, and described revolving fragment one end is respectively with the lock core shifting block be arranged on trundle on the master latch supporting plate and support and cooperate, and the other end is provided with a master latch lock-out state screens.
Also be provided with left and right secondary latch bolt in the described lock body, described left and right secondary latch bolt connects as one by contiguous block and master latch supporting plate, is provided with the bayonet lock that matches with the screens of master latch lock-out state on the described contiguous block.
Also be provided with latch bolt, slide block and drive link in the described lock body, described slide block one end is supported with latch bolt and is connected, and the other end and drive link one end are flexibly connected, and the described drive link other end and revolving fragment are flexibly connected.
Compared with prior art, the beneficial effects of the utility model are:
The magnetic element that is used for the screens of triggering master latch opening in the utility model magnetic automatic locking is installed in the lock body, need not protrude lock panel and touch doorframe, in lock body, finish trigger action but utilize with doorframe upper magnet two like magnetic poles repel each other or the principle that there is a natural attraction between the sexes, therefore less demanding to the fit clearance between door leaf and the doorframe, only needing door leaf can enter doorframe gets final product, thereby improved the reliability of locking a door, and this trigger architecture can not cause scratch to the outer lacquer of doorframe yet, and then guaranteed the aesthetic property of doorframe.
Description of drawings:
Introduce in detail the utility model below in conjunction with the drawings and specific embodiments.
Fig. 1 is the structural representation of the utility model magnetic automatic locking opening.
Fig. 2 is the structural representation of the overhanging state of the utility model magnetic automatic locking.
The specific embodiment:
As depicted in figs. 1 and 2, as a kind of embodiment of the present utility model, this magnetic automatic locking comprises lock body 1 and panel 2, be provided with master latch 3, master latch supporting plate 4, master latch opening mechanism 5, master latch opening screens 6 (namely when master latch is in opening, it is carried out spacing and prevents the screens that it is overhanging), master latch extension spring 7 in the lock body 1.Near panel 2 places activity one magnetic element 8 is set in that lock body 1 is interior, on doorframe zone that should magnetic element 8 is fixedly installed a magnet (meaning not shown in the figures), magnetic element 8 and magnet can be magnet or magnet steel, and the polarity of the two forward surface is identical.
Master latch opening screens 6 one ends rotate to arrange, and the other end cooperates with draw-in groove 31 clampings on being arranged on master latch 3.Magnetic element 8 and the free end of a driving lever 9 are supported and are connected or are fixedly connected with, and the other end of driving lever 9 rotates to arrange and support with the joint end of master latch opening screens 6 and cooperates, and is provided with on the driving lever 9 for its driving lever extension spring 91 that resets.
When locking a door, magnetic element 8 is near magnet, utilize the principle of the two two like magnetic poles repel each other to make magnetic element 8 lateral movement in the lock body, driving driving lever 9 rotates counterclockwise, driving lever 9 drives master latch opening screens 6 again and rotates counterclockwise, make its throw off with master latch 3 on the cooperating of draw-in groove 31, at this moment, master latch 3 is overhanging locking under the effect of master latch extension spring 7.
