The specific embodiment
Describe the utility model with reference to the accompanying drawings in detail.Fig. 1 has provided the oblique view as the lock body with anti-plugging function of preferred embodiment of the present utility model, dead bolt 3, the two spring arms that wherein show lock box 1, be arranged on dead bolt arm-tie 2 on the lock box 1, are connected with dead bolt arm-tie 2 be stuck in the torsion spring 5 on lock box 1 and the dead bolt arm-tie 2 and be arranged on dead bolt arm-tie 2 and dead bolt 3 between side plate 4.This lock body with anti-plugging function also comprise the connector 7 of fixedlying connected with dead bolt 3 and be arranged on dead bolt 3 and connector 7 between compression spring 6.Dead bolt 3 is ensconced in the lock box 1 in the ground, effect lower part of compression spring 6.One end of connector 7 keeps often contacting with dead bolt arm-tie 2.
Shown in Fig. 2 to 3, lock box 1 is provided with riveting post 13 with holes.Lock body also comprises the anti-plug device that is arranged in the lock box 1.Anti-plug device comprises anti-plug unit 9, reset unit 8 and removes unit 12.Anti-plug unit 9 rotatably is socketed on the riveting post 13.Removing unit 12 can be rotatably set between anti-plug unit 9 and the dead bolt arm-tie 2.Be inserted with screw 11 in the hole of riveting post 13 to limit the position of torsion spring 10 and anti-plug unit 9.Screw 11 along axis X pass torsion spring 10 successively, anti-plug unit 9 is inserted in the hole of riveting post 13.Fig. 4 is the oblique view of anti-plug unit.This anti-plug unit 9 has anti-spigot 90, the position 91 that resets, hole 92 and remove end 93; Fig. 5 and Fig. 6 have provided the oblique view and the front view of reset unit respectively.Reset unit 8 comprises anti-tongue 80, reset baffle block 81 and is socketed in reseting groove 82 on the riveting post 13.Reset unit 8 is arranged on the lock box 1 movably.Reset unit 8 is used to limit the position of anti-spigot 90.Reset baffle block 81 moves to the position 91 that resets at closing time.Reset baffle block 81 rebounds and the anti-spigot 90 of butt when opening the door.Remove unit 12 and have shift fork 120 and projection 121.The equipped square shafts of shift fork 120, during rotation and the backboard 20 of dead bolt arm-tie 2 keep in touch.Projection 121 drives when opening the door removes end 93 rotations.Be provided with compression spring 14 in the reseting groove 82.One end of compression spring 14 is connected on the riveting post 13.Anti-tongue 80 stretches out and indentation lock box 1 simultaneously with dead bolt 3 under the effect of compression spring 14.Remove unit 12 when opening the door and be accompanied by moving of dead bolt arm-tie 2 and rotate, thereby drive 9 rotations of anti-plug unit to allow dead bolt 3 indentation lock boxes 1.Be with torsion spring 10 on the riveting post 13.As shown in Figure 1, 2, the short spring arm of torsion spring 10 is inserted on the relevant position of lock box 1, and the bending place of long spring arm props up anti-plug unit 9.Torsion spring 10 is used to make anti-plug unit 9 to rotate to the rear of front apron 21 to prevent dead bolt 3 indentation lock boxes 1.Compression spring 14 places the reseting groove 82 of dead bolt 3 and is loaded on lock box 1 bottom.
When closing the door, in the time of dead bolt 3 indentation lock boxes, anti-tongue 80 contracts in indentation lock box the inside, and anti-plug unit 9 can rotate under the active force of torsion spring 10 automatically, arrives to reset baffle block 81 up to the position 91 that resets of anti-plug unit 9.At this moment, the anti-spigot 90 of anti-plug unit 9 is positioned at the rear of the front apron 21 of dead bolt arm-tie 2.In other words, in the process of dead bolt 3 indentation lock boxes, anti-plug unit 9 can prop up dead bolt arm-tie 2 and stop action, thereby realizes anti-plugging function.
When opening door lock by correct way, the mobile of arm-tie 2 turned clockwise shown in the shift fork 120 of releasing unit 12 was followed.When turning clockwise this action beginning in releasing unit 12, releasing unit 12 will drive anti-plug unit 9 simultaneously and be rotated counterclockwise.In other words, the projection 121 of removing unit 12 turns clockwise, and releasing end 93 rotations of contact and drive anti-plug unit 9.Thereby remove the anti-plugging function of dead bolt 3, make the dead bolt 3 can indentation lock box the inside.
When opening door, dead bolt 3 will eject lock box under the active force of compression spring 14.At this moment, because the active force of compression spring 14 greater than the active force of torsion spring 10, begins next circulation so automatically reset to initial position thereby anti-plug unit 9 will can not be subjected to the control of torsion spring 10 at this moment.
Should be noted in the discussion above that above-mentioned preferred implementation only is exemplary.Those of ordinary skill in the art will be appreciated that and can carry out multiple modifications and changes in the scope that is defined by the following claims.
