Abstract
The invention provides a theft-proof bolt guard block structure of a door lock, which comprises a bolt guard block, a fixed box, a pressure spring and an insertion preventing box. The fixed box is a rectangle box structure with an opening at one side, the two sides of the opening are provided with flanging, the flanging is lapped and fixed with the inside surface of the bolt guard block, a positioning lug boss is arranged on the inner side of the bottom surface of the fixed box, and the pressure spring is sleeved outside the positioning lug boss. The insertion preventing box is a rectangle box structure with an opening at one side, one of two sides of the opening is provided with a right-angled flanging, and the other side of the opening is provided with an oblique flanging. The insertion preventing box is arranged in the fixed box and obliquely arranged in a square hole of the bolt guard block, the right-angled flanging of the insertion preventing box is lapped on the inside surface of the bolt guard block, the oblique flanging of the insertion preventing box is exposed from the bolt guard block, and the bottom surface of the insertion preventing box is jacked by the top end of the pressure spring in the fixed box. The structure can effectively prevent the door lock from being opened by inserting a card so as to ensure the safety of a user.
Description
Technical field
The invention belongs to the door lock anti-theft technique.
Background technology
If security door is not locked the master lock tongue on the ahead market, insert from door leaf and doorframe slit with plastic cards and can stir the lockset latch bolt and just security door can be opened, make it lose due function, the safety that this will have a strong impact on the user causes bad impact.
Summary of the invention
The object of the invention is to the deficiency for the prior art existence, propose a kind of theft-proof bolt guard block structure of door lock, effectively prevent illegal opened door leaf.
Technical solution of the present invention is as follows:
A kind of theft-proof bolt guard block structure of door lock, the bolt protective block that it has the lockhole outside that is installed on the doorframe also includes fixed bin, stage clip and anti-insert box.
Wherein fixed bin has an opening at least, in the both sides of described opening flange is arranged, and the medial surface overlap joint of described flange and bolt protective block is also fixing, is provided with a location boss in inboard, fixed bin bottom surface, and described compression spring sleeve is outside positioning boss.
Described anti-insert box has an opening at least, and one side has the right angle flange in the both sides of described opening, and a side has oblique flange.
Described anti-plug is box-packed in fixed bin, and angle mount enters in the square hole of bolt protective block, its right angle flange is overlapped on the medial surface of bolt protective block, the activity surplus is pushed down and left to the side of box of being fixed, its oblique flange is exposed at the bolt protective block outside outward, its bottom surface is withstood by the stage clip top in the fixed bin, and described oblique flange exposes to the height in the bolt protective block outside greater than the width of crack between a door and its frame under the effect of stage clip.
Advantage of the present invention is as follows:
1, simple in structure, reliable in function.
2, do not affect use and the outward appearance of door.
3, prevent that effectively card from inserting unlatching, guarantees user's safety.
4, cost is low, is convenient to processing.
Description of drawings
Fig. 1 is the structure explosive view of a kind of specific embodiment of the present invention;
Fig. 2 is the front schematic view after the structure of Fig. 1 is assembled;
Fig. 3 is the schematic rear view after the structure of Fig. 1 is assembled;
Fig. 4 is that structure shown in Figure 1 is installed in the state diagram (when closing) on the door.
The specific embodiment
Describe structure of the present invention in detail below in conjunction with accompanying drawing:
As shown in Figure 1, the major part of this theft-proof bolt guard block structure of door lock has fixed bin 1, stage clip 2, anti-insert box 3 and bolt protective block 4.
In conjunction with Fig. 2 and Fig. 3 as seen, fixed bin 1 is the cuboid box of an opening, and there is flange 11 both sides of its opening, is used for overlap joint and is fixed on bolt protective block 4 inboards.Inboard, fixed bin 1 bottom surface is fixed with a columniform positioning boss 12, and stage clip 2 is enclosed within outside the positioning boss 12.Anti-insert box 3 also is the cuboid box of an opening, and at a side right angle flange 31 of its opening, a relative side has oblique flange 32.Bolt protective block 4 is conventional inwardopening door bolt protective block, and the perforate on this part is the latch bolt square hole.
During installation, anti-insert box 3 is contained in the fixed bin 1, anti-insert box 3 angle mounts are entered in the square hole of bolt protective block 4, its right angle flange 31 is overlapped on the inboard of bolt protective block 4, its oblique flange 32 outer bolt protective block 4 outsides that are exposed at, its bottom surface is withstood by stage clip 2 tops in the fixed bin 1, and tiltedly flange 32 exposes to the height in bolt protective block 4 outsides greater than the width of crack between a door and its frame under the effect of stage clip.
The positioning boss 12 that stage clip 2 is inserted in fixed bin 1 is outer and fixing.The flange 11 of fixed bin 1 both sides is overlapped on bolt protective block 4 inboards, to prevent that insert box 3 covers, and it also has a side to push down the right angle flange 31 of anti-insert box 3 and the activity surplus is arranged, fixed bin 1 and bolt protective block 4 is fixing, this moment, stage clip 2 contacted with anti-insert box 3 bottom surfaces, and it is withstood.When acting on effectively the oblique flange 32 of anti-insert box 3, stage clip 2 is namely compressed, but in the anti-insert box 3 part retraction bolt protective blocks 4.Namely anti-insert box 3 can be according to the size that acts on the power on the oblique flange 32 and part be stretched out or the square hole of retraction bolt protective block 4 in, and the oblique flange 32 of anti-insert box 3 contacts with the acting surface of power all the time.
Be illustrated in figure 3 as this structure and be installed in state on the door, door leaf 5, dead bolt 6, doorframe 7 are the conventional components on the door.When door leaf 5 cut out, the side of dead bolt 6 applied power in the oblique flange 32 of anti-insert box 3, stage clip 2 compressions, and the oblique flange 32 of anti-insert box 3 is close to the side of door leaf 5.If there is this moment the thin thing such as card to insert from the slit of door leaf and doorframe, just the chamfered portion that can not act on latch bolt 6 can effectively prevent illegal opened door leaf with latch bolt 6 fan 5 that pulls out that bride visits her parents with her husband for the first time after the wedding, worn vest as giving latch bolt 6.
