[specific embodiment]
A kind of outer dress lock, as shown in Figure 8, comprise lock housing 1, place the base plate 2 within the lock housing 1, pass described base plate sword iron 3, be fixed on the latch-up structure 5 on the base plate 2, be located at linkage 4 and the moving plate 6 of magnetic on the base plate, the rotation of sword iron 3 promotes linkage 4 and rotates, and linkage 4 drives described latch-up structure 5 and stretches.
As shown in Figure 1, a via hole 11 is arranged on the lock housing 1.The width of via hole 11 is preferably 40mm-70mm tolerable sword iron 3 and passes and translation therein greater than the width of sword iron 3 heads.The shape of via hole 11 is according to the difference of sword iron 3 and difference.The shape of via hole 11 was preferably square when sword iron 3 was flat.
As shown in Figure 2, base plate 2 is arranged on the lock housing 1.Have on the base plate 2 also to be provided with two hinge holes 21, the two ends of linkage 4 are connected with base plate 2 by hinge hole 21.Also be provided with pivoted hole 22 and through hole 23 on the base plate 2.Sword iron 3 passes the below that is positioned at linkage 4 behind via hole 11 and the through hole 23.Key inserts lockhole and drives sword iron 3 and rotate, and sword iron 3 rotating certain angle can promote linkage 4 after being preferably 45 ° and rotate.
As shown in Figure 3, sword iron 3 is a flat, and 11 of via holes are square, and the shape size of via hole 11 allows that sword iron 3 rotates therein.Sword iron 3 also can be cylindrical rod portion and square or erose head, and head passes the below that is positioned at linkage 4 behind lock housing 1 and the base plate 2, so the width of via hole 11 with get final product with the diameter of cylindrical rod portion is adaptive.
Linkage 4 contacts with the head of sword iron 3, but the swing of the rotation drivening rod mechanism 4 of sword iron 3, and the swing of linkage 4 drives the flexible of latch-up structure 5, opens latch-up structure with this, reaches the purpose of unblanking.
As shown in Figure 4, linkage 4 comprises vane 41 and two connecting rods 42.The two ends of vane 41 are hinged with two connecting rods 42 respectively, and the other end of two connecting rods 42 is hinged at hinge hole 21 places and base plate 2.Make between linkage 4 and the base plate 2 structure that forms parallelogram, can on base plate 2, swing.In the present embodiment, vane 41 is positioned at the top of sword iron 3, and sword iron 3 and connecting rod 42 are positioned at the homonymy of vane 41.The distance of vane 41 and sword iron 3 is less than half of sword iron 3 head widths, that is to say that can contact and promote vane 41 with vane 41 when sword iron 3 forwards certain angle to moves.In the present embodiment, the mobile retaining mechanism 5 drive dead bolts that can promote of vane 41 stretch.Owing to form the structure of parallelogram between linkage 4 and the base plate 2, utilize parallel four limit row afterburning principle that all can realize linkage 4 whole swings on any point, the position of sword iron 3 can not fixed, that is to say, when the accuracy of lockhole is not high, though move to some extent relative to accurate position the position of sword iron 3, still can drivening rod mechanism 4, realize unlocking function.In other embodiments, linkage also can adopt other structures outside the parallelogram, as long as sword iron 3 places described linkage one side movably and promote linkage when rotating in moving range, linkage drives flexible realization of latch-up structure and unblanks to get final product.
In other embodiments, between linkage 4 and retaining mechanism 5, be provided with the moving plate 6 of magnetic.The fixed end of the moving plate 6 of magnetic is hinged by pivoted hole 22 and base plate 2, free end and retaining mechanism 5 butts.Promoting the moving plate 6 of magnetic when vane 41 moves rotates around fixed end.Linkage 4 also comprises a driving lever 43.Driving lever 43 is arranged on the vane 41, can lay respectively at vertical the setting up in both sides of vane 41 with connecting rod 42, also can protrude in the plane at vane 41 places.When vane 41 moved, driving lever 43 cooperated with vane 41, promoted the moving plate 6 of magnetic better and rotated around its fixed end.
The course of work is as follows:
Key inserts lockhole can drive sword iron 3 rotations, because the head of sword iron 3 is square, when it turns an angle, during as 45 °, the vane 41 that can promote its top moves, and the moving plate 6 of vane 41 promotion magnetic rotates, and it is flexible to make moving plate 6 free ends of magnetic promote retaining mechanism 5 drive dead bolts.
Because the width of via hole 11 can be allowed sword iron 3 translation therein, when the door back gauge changes, can mobile lock housing 1 cooperate the needs (be exactly that sword iron 3 is mobile in via hole 11 this moment) of a back gauge.Move cooperating of plate 6 with linkage 4, magnetic again, dress lock outside can in the scope of 40mm-70mm door back gauge, normally using.
Those skilled in the art should understand, the above-mentioned primary structure that just provides the utility model embodiment, other necessary parts be dead bolt and make the spring etc. of the moving sheet reset of magnetic be also included within the structure of the present utility model for example.
