Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Embodiment 1 dead bolt overturn self-locking device
As shown in figures 1 to 6, a kind of dead bolt overturn self-locking device, the first torsion spring 8 comprise dead bolt 1, dead bolt being rotated unblank, to coordinate limit dead bolt and rotate the block 4 of unblanking, the second torsion spring 9 block being rotated limit dead bolt to rotate to unblank, make dead bolt blocks rotation and remove the restriction of block to dead bolt to make dead bolt rotate the driving mechanism of unblanking with dead bolt, block coordinates with the draw-in groove of dead bolt sidewall and limits dead bolt and rotate and unblank.Make dead bolt blocks rotation and remove the cam 2 that the restriction of block to dead bolt make dead bolt rotate the driving mechanism of unblanking to comprise motor 7 and be connected with machine shaft, the rotating shaft 3 of described motor, cam 2 are arranged with dead bolt 1 concentric, be provided with between described cam 2 and dead bolt 1 cam 2 rotate back down block 4 after dead bolt 1 just can be driven to rotate transmission mechanism.Described machine shaft 3 end is flat bar, and described cam 2 center is provided with through hole, described through hole hole wall is established two equally distributed teeth that machine shaft band moving cam is rotated mated with machine shaft end.Described transmission mechanism comprises groove 5 and driving lever 6, described groove 5 is located at dead bolt 1 end face, described driving lever 6 one end is fixedly arranged on cam 2 end face, and the other end is placed in groove 5, and the length of described groove 5 just can drive dead bolt rotation to be as the criterion to make cam 2 rotation back down the rear driving lever 6 of block 4.Described motor 7 is toothed gearing electric motor.Described dead bolt 1 is hook tongue.
As shown in Figure 2, toothed gearing electric motor 7 clockwise direction rotates, and is with moving cam 2 to rotate by machine shaft 3.As shown in Figure 3, cam 2 there is cam driving lever 6, be stuck in the dead bolt groove 5 of dead bolt 1, dead bolt 1 can be driven to rotate, but because dead bolt groove 5 is longer, therefore cam 2 has one section of idle stroke, dead bolt 1 can not be made at once to rotate, but first back down block 4, treat that the restriction of dead bolt 1 is removed, cam 2 acts on dead bolt groove 5 by cam driving lever 6, thus drives dead bolt 1 to rotate, and reach the object of unblanking in the maximum rotation angle that the effect of the first torsion spring 8 and toothed gearing electric motor 7 is issued to dead bolt 1, as shown in Figure 4.
At blocking, also can push block 4 aside with manual clockwise direction, remove the restriction of dead bolt 1, dead bolt 1 is under the first torsion spring 8 acts on, automatic clockwise direction rotates, also be with moving cam 2 to rotate, owing to there being one section of idle stroke between cam 2 and machine shaft 3, be free state simultaneously, so the rotation of dead bolt 1 is not by the restriction of machine shaft 3, dead bolt 1 under the first torsion spring 8 acts on, can reach maximum rotation angle, reaches the object of unblanking.
As shown in Figure 5, toothed gearing electric motor 7 counterclockwise rotates, be with moving cam 2 to rotate by machine shaft 3, cam 2 acts on dead bolt groove 5 by cam driving lever 6, thus drives dead bolt 1 to rotate, and the maximum rotation angle of dead bolt 1 is issued in the effect of toothed gearing electric motor 7, block 4 is under the effect of the second torsion spring 9 simultaneously, and automatic fall-back, in the draw-in groove of dead bolt 1, stops dead bolt 1 resilience under the first torsion spring 8 acts on, reach the object of locking, as shown in Figure 6.
Embodiment 2 is applicable to vertical hinged door
As shown in Figure 7, doorframe 13 is fixed on body of wall 14, and the dead bolt overturn self-locking device shown in Fig. 1-6 is installed on doorframe 13, and when vertical hinged door 12 is closed, dead bolt 1 drives the folding being issued to maximum anglec of rotation limiting door at toothed gearing electric motor 7.
As shown in Figure 8, when vertical hinged door 12 needs to open, drive dead bolt 1 to rotate by toothed gearing electric motor 7 until the folding of its no longer limiting door 12, or manual toggle block 4 removes its restriction to dead bolt 1, dead bolt 1 can rotate and make it no longer limit the folding of vertical hinged door 12 under the effect of the first torsion spring 8.
The safety contacted with dead bolt 1 for avoiding vertical hinged door 12 and avoid making a noise, dead bolt 1 with the contact surface of vertical hinged door 12 are provided with dead bolt rubber cushion 11.
Embodiment 3 is applicable to sliding door
As shown in Figure 9, dead bolt overturn self-locking device shown in Fig. 1-6 is installed on fixed gate 17, because dead bolt 1 is hook tongue, only a latch hook 15 mated with hook tongue need be installed in sliding door 16 corresponding hook tongue position, dead bolt 1 drives at toothed gearing electric motor 7 and is issued to the maximum anglec of rotation, latch hook 15 in sliding door 16 is subject to the restriction of dead bolt 1, and sliding door 16 can not be moved right.
As shown in Figure 10, when glass sliding door 16 needs to open, dead bolt 1 is driven to rotate until it no longer limits latch hook 15 by toothed gearing electric motor 7, or manual toggle block 4 removes its restriction to dead bolt 1, dead bolt 1 can rotate and make it no longer limit latch hook 15 under the effect of the first torsion spring 8, and glass sliding door 16 can move right and open.
In like manner, drawer is suitable for too.
The above; only preferred embodiment of the present utility model; it is not restriction the utility model being made to other form; any those skilled in the art of being familiar with can utilize the technology of above-mentioned announcement to be changed improvement; in every case be do not depart from technical solutions of the utility model content; according to the utility model technical spirit to any simple modification implementing above to do, still belong to the protection domain of technical solutions of the utility model.
