Abstract

The utility model provides a protecting block structure for an anti-inserting spring bolt. The structure comprises a spring bolt protecting block, a fixing box, a pressure spring, and an anti-inserting box, wherein at least one surface of the fixing box is open, turnup edges are arranged on two sides of the opening, the turnup edges are in lap joint and fixed with the inner side surface of the spring bolt protecting block, a positioning boss is arranged on the inner side of the bottom surface of the fixing box, and the pressure spring is sleeved outside the positioning boss; at least one surface of the anti-inserting box is open, a right-angled turnup edge is arranged on one side of the opening, and an inclined turnup edge is arranged on the other side of the opening; and the anti-inserting box is mounted in the fixing box and obliquely mounted in a square hole of the spring bolt protecting block, the right-angled turnup edge of the anti-inserting box is in lap joint with the inner side surface of the spring bolt protecting block, the inclined turnup edge of the anti-inserting box is exposed on the outer side of the spring bolt protecting block, and the bottom surface thereof is supported by the top end of the pressure spring in the fixing box. The structure can effectively prevent a card from being inserted into the spring bolt to open, thereby guaranteeing the safety of a user.

Description

A kind of Anti-inserting lock bolt guard block structure

Technical field

The utility model belongs to the door lock anti-theft technique.

Background technology

Security door can be stirred the oblique tongue of lockset with plastic cards from door leaf and the insertion of doorframe slit and just security door can be opened if main dead bolt is not locked on the market a few days ago, makes it lose due function, and the safety that this will have a strong impact on the user causes bad influence.

Summary of the invention

The purpose of this utility model is to propose a kind of Anti-inserting lock bolt guard block structure at the deficiency of prior art existence, effectively prevents from illegally to open door leaf.

Technical solution of the present utility model is as follows:

A kind of Anti-inserting lock bolt guard block structure, its dead bolt with the lockhole outside that is installed on the doorframe protects piece, also includes fixed bin, stage clip and anti-plug box.

Wherein fixed bin has an opening at least, in the both sides of described opening flange is arranged, and described flange and dead bolt protect the medial surface overlap joint of piece and fix, and is provided with a location boss in inboard, fixed bin bottom surface, and described compression spring sleeve is outside positioning boss.

Described anti-plug 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 is gone into dead bolt and is protected in the square hole of piece, its right angle flange is overlapped on the medial surface that dead bolt protects piece, the activity surplus is pushed down and left to the side of box of being fixed, its oblique flange is exposed at dead bolt outward and protects the piece outside, its bottom surface is withstood by the stage clip top in the fixed bin, and described oblique flange exposes to dead bolt and protects the width of the height in the piece outside greater than crack between a door and its frame under the effect of stage clip.

Advantage of the present utility model is as follows:

1, simple in structure, reliable in function.

2, do not influence the 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.

Fig. 1 is the structure explosive view of a kind of specific embodiment of the utility model;

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 utility model in detail below in conjunction with accompanying drawing:

As shown in Figure 1, the major part of this Anti-inserting lock bolt guard block structure has fixed bin 1, stage clip 2, anti-plug box 3 and dead bolt to protect piece 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 dead bolt protecting piece 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-plug 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.Dead bolt protects piece 4 and protects piece for conventional inward with dead bolt, and the perforate on this part is oblique tongue square hole.

During installation, anti-plug box 3 is contained in the fixed bin 1, anti-plug box 3 angle mounts are gone into dead bolt to be protected in the square hole of piece 4, its right angle flange 31 is overlapped on the inboard that dead bolt protects piece 4, be exposed at dead bolt outside its oblique flange 32 and protect piece 4 outsides, its bottom surface is withstood by stage clip 2 tops in the fixed bin 1, and tiltedly flange 32 exposes to dead bolt and protects the width of the height in piece 4 outsides greater than 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 dead bolt protects piece 4 inboards, anti-plug box 3 is covered, and it also has a side to push down the right angle flange 31 of anti-plug box 3 and the activity surplus is arranged, it is fixing that fixed bin 1 and dead bolt are protected piece 4, this moment, stage clip 2 contacted with anti-plug box 3 bottom surfaces, and it is withstood.When masterpiece was used for the oblique flange 32 of anti-plug box 3, stage clip 2 promptly was compressed, but anti-plug box 3 part retraction dead bolts protect in the piece 4.Be that anti-plug box 3 can partly stretch out according to the size that acts on the power on the oblique flange 32 or the retraction dead bolt protects in the square hole of piece 4, and the oblique flange 32 of anti-plug box 3 contact 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 the oblique flange 32 of power in anti-plug box 3, stage clip 2 compressions, and the oblique flange 32 of anti-plug box 3 is close to the side of door leaf 5.This moment is if there is thin thing such as card to insert from the slit of door leaf and doorframe, just the chamfered portion that can not act on oblique tongue 6 can effectively prevent from illegally to open door leaf with oblique tongue 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 oblique tongue 6.
