Abstract

A kind of magnetic force lock core with the magnetic switch door lock has noise, wearing and tearing and uneasy congruent problem when having solved the manually opened device switch of existing interior door lock; The utility model comprise locking bar and with the corresponding jam plate of locking bar, its special character is, magnetic patch is equipped with in front portion at locking bar, an associated driving lever is arranged at the rear portion of locking bar, have on the jam plate one with locking bar on the magnetic patch inhaled mutually of magnetic patch, utilize the suction of two magnetic patch to make locking bar enter into the groove of jam plate, door lock is lived, utilize driving lever that locking bar is separated with jam plate again, door is opened; Advantage is; not collision and friction in the process of opening and closing; not only reduced to open the door or noise at closing time; make people's dwelling environment more comfortable, and, the surface of doorframe and jam plate can not damaged; it is attractive in appearance that door is remained; and stopped the chance that locking bar contacts with human body, with the protection children, avoid coming to harm.

Description

The magnetic force lock core

Technical field

The utility model belongs to a kind of door lock open and close device, particularly a kind of magnetic force lock core with the magnetic switch door lock.

Background technology

Interior door lock of the prior art has two cover switching devices usually, and one applies mechanically handle opens or close, and another set of usefulness is key operated or close.Mainly form by lock core, dead bolt, spring and with the jam plate that dead bolt matches with key operated device, the purposes of this covering device is with on the door lock, and must have anti-theft feature with key operated.The device of opening with handle mainly by locking bar, dial insert, back-moving spring, square shaft, handle and jam plate etc. constitute, the purposes of this covering device is that door is closed, after door was closed, wind can not blow it open, but can open with handle, thereby it does not possess anti-theft feature.Have dead bolt on the described locking bar, the lockhole on dead bolt and the jam plate matches, and back-moving spring is installed on the locking bar, handle has two, installs one respectively the inside and outside of door, and handle drives to dial to insert by square shaft and rotates, dial and insert the motion of drive locking bar, dead bolt and jam plate are separated, door is opened.The subject matter that this covering device exists is, 1, opening the door or at closing time, dead bolt and doorframe and jam plate are collided, can send impact sound, and can influence people's rest at night.2, dead bolt can rub when contacting with doorframe and jam plate, causes the wearing and tearing on doorframe and jam plate surface, influences the attractive in appearance of door.3, after door was opened, dead bolt was in outdoors, and children are constituted unsafe factor.

Summary of the invention

The technical problems to be solved in the utility model is, when overcoming the manually opened device switch of existing interior door lock noise, wearing and tearing and uneasy congruent problem arranged, and a kind of noiselessness is provided, does not does not wear and tear, the magnetic force lock core with the magnetic switch door lock safe in utilization.

The utility model comprise locking bar and with the corresponding jam plate of locking bar, its special character is, magnetic patch is equipped with in front portion at locking bar, an associated driving lever is arranged at the rear portion of locking bar, have on the jam plate one with locking bar on the magnetic patch inhaled mutually of magnetic patch, utilize the suction of two magnetic patch to make locking bar enter into the groove of jam plate, door lock is lived, utilize driving lever that locking bar is separated with jam plate again, door is opened.

Advantage of the present utility model is:

1, utilize the suction of magnetic patch to make locking bar enter into the groove of jam plate, and utilize driving lever that locking bar is separated with jam plate, thereby not collision has reduced to open the door or noise at closing time greatly in the process of opening and closing, makes people's dwelling environment more comfortable.

2, opening the door or at closing time, the surface of locking bar and doorframe and jam plate does not have friction, thereby, can not damage the surface of doorframe and jam plate, it is attractive in appearance that door is remained.

When 3, door was opened, locking bar was in retracted mode, all is contained in the door, has stopped the chance that locking bar contacts with human body, with the protection children, avoided coming to harm.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the vertical view of Fig. 1;

Fig. 3 is that the A of Fig. 1 is to view.

The specific embodiment

As shown in drawings, the utility model comprises locking bar 6 and jam plate 1, and locking bar 6 and jam plate 1 usefulness nonferromugnetic material are made, and jam plate 1 is installed on the doorframe, and locking bar 6 is installed in the lock body, and lock body is installed on the interior door, and jam plate 1 is corresponding with locking bar 6; A groove is arranged in the front portion of locking bar 6, magnetic patch 5 is housed in the groove, magnetic patch 5 is a permanent magnet, magnetic patch 5 usefulness backing plate 4 and screw, the shape of described groove and magnetic patch 5 is not limit, the groove of present embodiment and magnetic patch 5 are cylindrical, also can adopt square, rectangle or other shapes, all do not influence its use; An associated driving lever 7 is arranged at the rear portion of locking bar 6, driving lever 7 usefulness nonferromugnetic materials are made, two inserted links on the top of driving lever 7, two inserted links match with the rear portion of locking bar 6, and it is stirred backward, and a square hole is arranged at the bottom of driving lever 7, the square shaft of packing in the square hole, rotate so that drive driving lever 7, thereby stir locking bar 6, lock is opened with handle; The groove that on jam plate 1, has a front portion with locking bar 6 to match, be equipped with in the groove one with locking bar 6 on the magnetic patch 2 inhaled mutually of magnetic patch 5, magnetic patch 2 is a permanent magnet, magnetic patch 2 usefulness backing plates 3, screw and nut are fixed; During assembling, the N utmost point of magnetic patch 2 should be extremely relative with the S of magnetic patch 5, and perhaps the S utmost point of magnetic patch 2 is extremely relative with the N of magnetic patch 5, guarantees that both attract each other; When door was shut, locking bar 6 was corresponding with jam plate 1, and magnetic patch 2 and magnetic patch 5 attract each other, and both suction makes locking bar 6 enter into the groove of jam plate 1, and door lock is lived; When opening the door, turning handle drives driving lever 7 by the square shaft in the door lock and rotates, and driving lever 7 drives locking bar 6 and retreats, and locking bar 6 is separated with jam plate 1, and door lock promptly is opened.

Claims

1, a kind of magnetic force lock core, comprise locking bar and with the corresponding jam plate of locking bar, it is characterized in that, in the front portion of locking bar magnetic patch is housed, an associated driving lever is arranged at the rear portion of locking bar, have on the jam plate one with locking bar on the magnetic patch inhaled mutually of magnetic patch.
