Description

Be used for the burglar-proof mechanism on the door

Technical field

The utility model relates to a kind of structure on the door, specifically, relates in particular to the burglar-proof mechanism that is used on the door.

Background technology

As shown in Figure 1, the burglar-proof mechanism on the existing door (like anti-theft safety door, steel door) comprises dead bolt 1 and lockhole 2, and wherein dead bolt 1 is located on the door leaf 3, and dead bolt 1 links to each other with lockset or drive unit 4 on the door leaf 3.Said lockhole 2 is opened in the moulding 6 corresponding on doorframe, and the angle that forms between the axial line of dead bolt 1 and the above-mentioned moulding 6 simultaneously is 90 ° (axial line and the above-mentioned moulding 6 that are dead bolt 1 are perpendicular), and the direction of axis line of dead bolt 1 is equal to the direction of motion of dead bolt 1.At closing time, said dead bolt 1 inserts in the lockhole 2 under the drive of lockset or drive unit 4, thereby realizes antitheft.

When the robber forced open the door with the rod kind tool, the direction and the said moulding 6 of dead bolt 1 suffered sled power were perpendicular, again because the axial line and the said moulding 6 of dead bolt 1 are perpendicular; The direction of dead bolt 1 suffered sled power and the direction of axis line of dead bolt 1 (also being the direction of motion of dead bolt 1) are paralleled; Thereby cause dead bolt 1 under the effect of sled power, very easily from lockhole 2, to withdraw from, and then the robber is pried open door, cause traditional structure to lose efficacy; And the forfeiture anti-theft feature, be badly in need of solving the problems of the technologies described above for this reason.

The utility model content

The utility model technical problem to be solved is to provide a kind of burglar-proof mechanism that is used on the door, and it can prevent effectively that the robber from prying open door.

The technical scheme of the utility model is following: a kind of burglar-proof mechanism that is used on the door; Comprise dead bolt (1) and lockhole (2), wherein dead bolt (1) is located on the door leaf (3), and dead bolt links to each other with lockset or drive unit (4) on the door leaf (3); It is characterized in that: said lockhole (2) is opened on boss (5); This boss (5) is located on the moulding (6) of doorframe, forms angle (θ) between the axial line of said dead bolt (1) and this moulding (6), and 0 °≤(θ)＜90 °; At closing time, dead bolt (1) inserts in the said lockhole (2).

Compare with traditional structure; The utility model is opened said lockhole (2) on boss (5); This boss (5) is located on the moulding (6) of doorframe, and with the angle (θ) that forms between said dead bolt (1) axial line and this moulding (6) by original 90 ° be adjusted into >=0 °, and＜90 °.

When the robber forced open the door with the rod kind tool, the direction of dead bolt 1 suffered sled power and said moulding (6) were perpendicular, because the angle of formation is adjusted into 0 °≤θ＜90 ° between the axial line of dead bolt (1) and the above-mentioned moulding (6); And the direction of axis line of dead bolt (1) is equal to the direction of motion of dead bolt (1), so the angle that forms between the direction of motion of the direction of dead bolt 1 suffered sled power and dead bolt 1 equals above-mentioned angle (θ), so just can significantly increase the difficulty that the robber pries open door; Der Rauber Hotzenplotz difficulty that door is pried open is also big more more for the angle of angle (θ); Thereby avoid dead bolt 1 under the effect of sled power, from lockhole 2, to withdraw from well, and then prevent that effectively the robber from prying open door, guarantee the normal operation of anti-theft feature; Be skillfully constructed; Simple in structure, easy to make, overcome the defective of traditional structure well; Have good technological value and potential economic benefit, be suitable for the large-scale promotion utilization.

As second embodiment of the utility model, the angle that forms between the axial line of said dead bolt (1) and the moulding (6) is 0 °, and promptly the axial line of dead bolt (1) and moulding (6) parallel.In the present embodiment, when the robber forced open the door with the rod kind tool, the direction of dead bolt 1 suffered sled power was vertical each other with the direction of motion of dead bolt 1, and robber's difficulty that door is pried open is maximum in this case, thereby further improved the pick-proof performance of the utility model.

In order to play purpose attractive in appearance, said dead bolt (1) is located at the inside of door leaf (3), and the end of door leaf (3) locates to be provided with open slot (3a) near said moulding (6), at closing time, dead bolt (1) and boss (5) all stretch in this open slot (3a).

Beneficial effect: the utility model can significantly increase the difficulty that the robber pries open door, thereby avoids dead bolt under the effect of sled power, from lockhole, to withdraw from well, and then prevents that effectively the robber from prying open door; Guarantee the normal operation of anti-theft feature, be skillfully constructed, simple in structure; Easy to make; Overcome the defective of traditional structure preferably, had good technological value and potential economic benefit, be suitable for the large-scale promotion utilization.
