Abstract
The present invention relates to a burglary-resisting lock for rolling gate. Its taperad end is fixed on the collar-beam of rolling gate, and its striking plate is controlled by said tapered end, and can be leftwards and rightwards slipped, and said stricking plate is formed from two portions which are crossed perpendicalarly, over the lock box a lock plate is sot, and said lock plate is equipped with a convex hole. Said burylary-resisting lock of rolling gate is simple in structure, easy to manufacture, can not change orginal unlocking mode, and is low in cost, safe and firm, can effectively prevent rolling gate, from being picked.
Description
The present invention relates to a kind of theftproof lock, relate in particular to the theftproof lock that is applied to rolling-gate.
Existing rolling-gate lock box is exposed to ground, and is both dangerous attractive in appearance, inconvenient again.Chinese patent 96243298.9 disclosed " improvement of rolling gate door lock ", it with the both sides of tapered end respectively establish one by tapered end control can about flexible strip dead bolt, it is corresponding higher that dead bolt need be provided with two costs, complex structure; The bottom of strip dead bolt also links L shaped dead bolt, and its direction is respectively to the left and right sides, so easily pries open L shaped dead bolt from the side, and is dangerous.
The objective of the invention is under the situation of the mode of unblanking that does not change original door lock, to reduce cost in order to overcome the deficiencies in the prior art, the lock box good concealment, safety firmly attractive in appearance, prevent that rolling-gate from being prized very effectively.
In order to achieve the above object, the present invention is by the following technical solutions: tapered end is fixed on the bottom girder of rolling-gate, dead bolt is flexible about being controlled by tapered end, dead bolt is that the two parts that intersect vertically are formed " " shape, jam plate is set above lock box, jam plate has the hole of convex, and the male ports bottom of jam plate is similar to dead bolt " " shape bottom shape.Dead bolt is provided with latch hook, and bumper is fixed on the angle steel of bottom girder.The bottom lengths of dead bolt is smaller or equal to the maximum caliber of jam plate male ports, and greater than the male ports lowest calibre, the lowest calibre of jam plate male ports is wider than the thickness of dead bolt.The lock box bottom has reinforced hole.Lock box and jam plate are fixed with union piece.
The present invention forms " " shape with the dead bolt two parts that are designed to intersect vertically, and jam plate is set above lock box, and jam plate has male ports, can effectively rolling-gate and jam plate be connected to become an integral body, and testing the antitheft power of deciding of this rolling-gate by the power table is 4.8 horsepowers.Dead bolt is provided with latch hook, and bumper is fixed on the angle steel of bottom girder, can prevent that lock box is embedded in underground with the cement pouring, make rolling-gate overall appearance and safety firmly from prying open.Dead bolt only need be provided with one, and is simple in structure, reduced cost.
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is the structural representation of burglary-proofing lock for rolling door embodiment one.
Fig. 2 is dead bolt embodiment one structural representation.
Fig. 3 is jam plate embodiment one structural representation.
Fig. 4 is the vertical view of dead bolt embodiment two.
Fig. 5 is the vertical view of jam plate embodiment two.
Embodiment one
Embodiment two
Be embedded in lock box 1 underground, it and ground are fixed from reinforced hole 3 with two setscrews, water with cement again, above lock box 1, be screwed jam plate 2, jam plate 2 has the hole of convex, the male ports bottom is circular, tapered end is fixed on the rolling-gate bottom girder, dead bolt 5 is flexible about being controlled by tapered end, and dead bolt 5 is formed " " shape for the two parts that intersect vertically, and the lower end is circular, dead bolt 5 middle parts are provided with latch hook 6, bumper 4 is fixed on the angle steel of bottom girder, and the diameter of a circle of jam plate 2 male ports is corresponding with the bottom lengths of dead bolt 5, and the lowest calibre of jam plate 2 male ports is wider than the thickness of dead bolt 5.
