Detailed description of the invention

Accompanying drawing, only for exemplary illustration, can not be interpreted as the restriction to this patent; In order to better the present embodiment is described, some parts of accompanying drawing have omission, zoom in or out, and do not represent the size of actual product; To those skilled in the art, in accompanying drawing, some known features and explanation thereof may be omitted is understandable.

In description of the present utility model, it should be noted that, unless otherwise clearly defined and limited, term " installation ", " connection " should be interpreted broadly, and such as, can be fixedly connected with, also can be removably connect, or connect integratedly; Can be mechanical connection, also can be electrical connection; Can be directly be connected, also can be indirectly connected by intermediary, the connection of two element internals can be said.For the ordinary skill in the art, concrete condition above-mentioned term can be understood at concrete meaning of the present utility model.Below in conjunction with drawings and Examples, the technical solution of the utility model is described further.

As shown in Figure 1, a kind of safe-guard door lock, comprise lock body 1, panel 2, to be fixed on panel 2 and the latch assembly matched with lock body 1 and the door handle 3 controlling latch assembly, door handle 3 is provided with safety button 4 and rotary spacing device, rotary spacing device one end is connected with safety button 4, the other end is connected with latch assembly, by arranging safety button 4 on door handle, need maintenance to pin safety button 4 during use could open the door, can prevent lawless person from carrying out stealing into room, effectively can protect the work property of numerous people, wherein, rotary spacing device comprises the fixed leg 5 be fixed on panel 2, plug blades 6, angle positioning sheet 7 and the blocking tab 8 leant with fixed leg 5, plug blades 6 one end is connected with safety button 4, the other end is successively through angle positioning sheet 7 and blocking tab 8, and be connected with latch assembly, at this, safe-guard door lock is under the effect not having external force, fixed leg 5 can be locked at any time after blocking tab and to be resetted, increase the difficulty of lawless person's picking lock, probability into room theft is minimized.

In the utility model, blocking tab 8 is provided with the groove or through hole that match with fixed leg 5, by groove or through hole, fixed leg 5 is made to pin blocking tab 8 when locking, blocking tab can not be rotated, reach the object of locking, and in the present embodiment, latch assembly comprises square shaft 9 and spring 10, spring 10 one end is embedded on square shaft 9, the other end is embedded in plug blades 6, stretched or Compress Spring 10 by plug blades 6, make square shaft 9 near lock body, at this moment, door is closed, or make square shaft 9 leave lock body, at this moment, door is closed, in addition, square shaft 9 and plug blades 6 are equipped with screens, spring 10 is fixed between square shaft 9 screens and plug blades 6 screens, by arranging spring 10 between square shaft 9 screens and plug blades 6 screens, spring 10 can not be shifted because of collision, screens can better fixing spring 10, it is made not to be subjected to displacement.

In addition, square shaft 9 is provided with open slot 11, open slot 11 and plug blades 6 size match, by plug blades 6 being injected in the open slot 11 on square shaft 9, plug blades 6 is made better to control the tension and compression of square shaft 9, in addition, also comprise meson 12, meson 12 is fixed between square shaft 9 screens and spring 10, and the use of meson 12 can reduce the loss of square shaft 9 screens, extends the application life of safe-guard door lock.

As shown in Figure 2, after we go out to lay the key under the door, blocking tab 8 is under the effect of spring 10 elastic force, fixed leg 5 on panel 2 will inject in blocking tab 8, if now turn the handle 3, blocking tab 8 also can be rotated thereupon, but is seized blocking tab 8 due to now fixed leg 5, it can not be rotated thus make door handle 3 not rotate yet, such door is not just opened.

As shown in Figure 3, angle positioning sheet 7 is in the process of rotating, and when angle positioning sheet 7 turns to certain angle, fixed leg 5 can limit angle positioning sheet 7 position, angle positioning sheet 7 can not be rotated further after turning to certain angle, door handle 3 can not be rotated down always.

As shown in Figure 4, when we need revolving door handle 3 to open the door in doors, with hand, safety button 4 is inwardly pressed tight, now pin sheet 6 inwardly will advance blocking tab 8, force it to leave fixed leg 5 and stop scope, so we just can turn the handle 3 realization enabling objects, due to lawless person is put in instrument by modes such as opals within doors can not be continual by tight safety button 4, so our novel safe-guard door lock just can guarantee that household gate can not have been stolen from utilizing cleek or film to open the door outdoors by offender.

In figure, describe position relationship only for exemplary illustration, the restriction to this patent can not be interpreted as; Obviously, above-described embodiment of the present utility model is only for the utility model example is clearly described, and is not the restriction to embodiment of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all embodiments.All do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., within the protection domain that all should be included in the utility model claim.
