The specific embodiment

Diagram is first kind of embodiment schematic diagram of the utility model, and in this mode, this device is installed on the security door frame 9.As shown in Figure 1, 2, 3, housing 1 base plate is stuck on the security door frame 9, and housing 1 base plate rear portion is provided with hold-down screw 8, holds out against frame 9 by hold-down screw 8 and fixes this device.Adopt the connected mode of this kind clamping, conveniently on existing security door, install, do not need existing security door is done any change, and, installation, convenient disassembly, highly easy to adjust.Striker 2, horizontal spring 3, support spring 4 and fixture block 5 are set in the housing 1, striker 2 is supported on the axle 10, and can rotate around axle 10, striker 2 ends have inside flanging 11, do not do the time spent there being external force, striker 2 is protruding under the effect of horizontal spring 3, under the effect of support spring 4, inwardly rotate, make flanging 11 be stuck in security door frame 9 places, owing to the obstruction of flanging 11, security door can not be in place, do not lock when security door cut out, it is all very tight that existing security door designs, and very thin flanging 11 exists just can make safe-guard door lock not go up.Housing 1 surface is provided with keyhole 6 and hand push button 7, as shown in Figure 3, keyhole 6 and hand push button 7 align striker 2 parts that support spring 4 supports, insert key by keyhole 6, can make support spring 4 pressurizeds, striker 2 is outwards rotated around axle 10, in the rotation process, striker 2 can rise to the step place that certain angle can be stuck in fixture block 5, as shown in Figure 5 dotted portion along rising on the inclined-plane of fixture block 5, at this moment, the flanging 11 of striker 2 breaks away from frame 9, as shown in Figure 4, and more at closing time, door can freely bang into striker 2 in the housing 1, no longer influence the in place of security door, the while, striker 2 was pressed towards in the housing 1 along with security door closes, striker 2 breaks away from fixture block 5, when door was opened again, striker 2 was protruding under the effect of horizontal spring 3 again, was stuck on the security door frame 9 inside rotation the under the effect of support spring 4.So, this device has been realized a function, needs before going out to throw keyhole 6 with key, makes striker 2 break away from the restriction state that is stuck in frame 9, could door lock is dead, thus effectively remind user's band key of going out.The action principle of hand push button 7 is the same, and difference is that use occasion has any different, and people just need not use key indoor inwardly at closing time, can close the door by this button 7, are easy to use.

The utility model also can be installed on the security door, and but, this kind embodiment need necessarily be reequiped existing security door, and the installation of need punching on security door is installed and the relative trouble of adjustment.

The utility model can also directly be contained in security door or security door frame 9 inside, when the production and processing of security door, just the design of this device is entered, these two kinds of embodiments, it is compacter that this device can design, this device case 1 can combine together with security door or security door frame 9, and is more succinct in appearance attractive in appearance.

Above-mentioned three kinds of embodiments, its internal construction is identical substantially with first kind of embodiment, and main difference is that the position of housing 1 installation is different, no longer carries out accompanying drawing at this and represents.

When the utility model was installed on security door or the security door frame 9, its outward appearance can be designed to various animal and plant shapes such as tiger, trees, to increase decoration function.
