The purpose of this utility model is, a kind of Anti-theft handle is provided, and it can be installed in the outside of door lock lockhole, plays antitheft purpose.

A purpose more of the present utility model is that a kind of Anti-theft handle is provided, and it is simple in structure, installs and makes easily.

The utility model safe-guard door lock, comprising leader's body is arranged: a narrow wall of fan-shaped key channel, generally be fan-shaped, its scallop one side and handle body inwall cambered surface upper side are affixed; One lockhole protecting cover, the inwall of its both end sides and handle body up and down 2 affixed, a side straight flange of its side wall surface and narrow wall of fan-shaped key channel is affixed; Handle body is the semicircle arcuation, on the wall of handle body, approximately apart from the upper end 1/4 place along its major axis to the last keyhole that has a rectangle, the both end sides of handle body respectively has a kink, kink is general like the rectangle plate body, one side has square groove on the surface of kink, at the center of square groove one circular hole is arranged; Narrow wall of fan-shaped key channel is that plate body bending forms, and the centre is formed with fan-shaped key road; The lockhole protecting cover generally seemingly is a strip, and there is the lockhole of the circle cover plate of screening the centre, and two ends have protruded out a protecting cover side arm, the round keyhole of centre screen cover plate in the middle of prolong the following keyhole that direction of principal axis has a rectangle; Handle body is general to have an opening like an annulus, and its opening two ends and lock collar are affixed.

For further specifying feature of the present utility model and effect, below in conjunction with drawings and Examples the utility model is described further, wherein:

Fig. 1 is a schematic perspective view of the present utility model.

Fig. 2 is the schematic perspective view of the narrow wall of fan-shaped key channel assembly among Fig. 1.

Fig. 3 is the schematic perspective view of the lockhole protecting cover among Fig. 1;

Fig. 4 is user mode figure of the present utility model, and shows the process of unblanking;

Fig. 5 is the structural representation of another embodiment of the present utility model;

At first, see also Fig. 1, be schematic perspective view of the present utility model and component diagram to shown in Figure 3.Comprising leader's body 10 is arranged, handle body 10 is a circular shape, and its cross section is a rectangle, or circular arc.At the two ends of handle body 10 kink 101 is arranged respectively, this kink 101 is general like rectangle, and the plane of two kinks 101 is on the horizontal plane; Upper surface at each kink 101 has a square groove 12, has a circular hole 121 at the center of square groove 12, and for penetrating of screw 122, square groove 12 is inserted for the square spigot 123 of the tail end of screw 122; About 1/4 place in handle body 10 upper ends, is inserted for the key of the lock that opens the door to the last keyhole 11 that has a rectangle along major axis.

One narrow wall of fan-shaped key channel 20 (among Fig. 2), it is to form with sheet material bending, there is a fan-shaped key road 22 centre, all there is opening on one side and circular arc limit, only its base is a closed, circular arc limit one side of this narrow wall of fan-shaped key channel 20, affixed with the place, internal face top of handle body 10, the thickness of narrow wall of fan-shaped key channel 20 is less than the width of handle body 10.

One lockhole protecting cover 30 (among Fig. 3), it is general like a strip, there is the lockhole of the circle cover plate 30 ' of screening the centre of this lockhole protecting cover 30, the lockhole of the circle in the middle of this lockhole protecting cover 30 cover plate 30 ' of screening can optionally be made the specification of the diameter that differs in size, its diameter is big more, its antitheft function is strong more, but also increased us relatively and utilized the time of key unlocking, be extended with the cover plate side arm 32 of screening at the screen two ends of cover plate 30 ' of the lockhole of circle, the lockhole on lockhole protecting cover 30 screen the center of cover plate 30 ' along major axis to the following keyhole 31 that has a rectangle; 2 Joints up and down of protecting cover side arm 32 two ends at these lockhole protecting cover 30 two ends and the internal face of handle body 10; One side of while lockhole protecting cover 30 and a side Joint of narrow wall of fan-shaped key channel 20; The screen base of the following keyhole 31 on the cover plate 30 ' of the inner bottom surface in this fan-shaped key road 22 and lockhole is equal.

Seeing also shown in Figure 4ly again, is to be user mode figure of the present utility model, and shows the process of unblanking.Wherein handle body 10 usefulness screws 122 are mounted on the door-plate 50, and cover is buckled in the front of door lock 302, and with the following lockhole 31 on the lockhole protecting cover 30 in alignment with the lockhole on the door lock 302 301.When opening the door, earlier key 40 is inserted from the last keyhole 11 on the handle body 10, the fan-shaped key road 22 of the head of its key 40 by narrow wall of fan-shaped key channel 20 stretches out in screen following keyhole 31 (the A position of key 40 among Fig. 4) on the cover plate 30 ' of lockhole, then, key 40 free-fallings are in the bottom (the B position of key 40 among Fig. 4) in fan-shaped key road 22, because of the front end of its key has been exposed to down outside the keyhole 31, the finger that turns round and look at personnel selection can pinch the leading section of key 40, and be inserted in the lockhole 301 on 3 door locks 302, when key 40 is inserted into the end, the tail end of its key stretches out in down outside the keyhole 31 just, and be in the space 60 of unblanking among Fig. 4, and can supply staff screw key 40, door lock 302 is opened.When after opening door lock, desiring to withdraw from key 40, with finger key 40 is fallen back on the end earlier, this moment, the tip of key 40 exposed to down keyhole 31 slightly, press down with the tip of finger again key 40, make the shank perk of key 40, the shank of key 40 upwarps supreme keyhole 11 places (returning back to aforesaid A position), and we can take out key 40 with the another hand.Or at the shank of the key place of key 40 a fixed rope body, when earlier key 40 being fallen back on the end, lift the rope body that exposes to keyhole 11 places with finger, can be with key 40 taking-ups.

What wherein need further specify is, after key 40 is placed in keyhole 11, be slightly larger than the thickness of key 40 because of the narrow wall in its fan-shaped key road 22, so can not take place key 40 insert behind the keyhole 11 side, because of the width of 22 bottoms, fan-shaped key road length,, the head of key 40 can not reveal the situation of keyhole 31 down again so also can not taking place less than key 40.

Seeing also shown in Figure 5ly again, is another embodiment of the present utility model, and its structure substantially is identical in previous embodiment, has no longer carefully described.Its difference is in, the side of handle body 80 general like circular, tool one peristome, and both ends and the lock collar on the door lock 70 of its opening are affixed, just handle body 80 and lockset are connected as a single entity.

The utility model compared with prior art, on the basis of the structure that does not change original lockset, Can reach the purpose that prevents from utilizing the skeleton key theft, the utility model also has the structure letter simultaneously List and make the advantages such as easy.
