Abstract
The utility model relates to a pry-proof device of a theft-proof door. One side of a door body is connected with one side of a door frame through a hinge; the other side of the door body and the other side of the door frame are respectively provided with a main lock point and a side lock point. The door body is provided with a pry-proof folding edge. The door frame is provided with a groove corresponding to the pry-proof folding edge. The main lock point is connected with the side lock point through a linking mechanism, the side lock point and the main lock point are arranged in the front and the back vertical directions, and one side of the groove on the door frame corresponding to the side lock point is provided with a lock hole of the side lock point. The pry-proof folding edge of the door body comprises an inner side folding edge and an outer side folding edge which are connected, and the lock hole of the side lock point on the pry-proof folding edge is only arranged on the inner side folding edge. Because the side lock point is wrapped in the pry-proof folding edge, destroyers can not destroy the side lock point and the main lock point even if the destroyers pry off the pry-proof folding edge. Therefore, the utility model has very ideal pry-proof performance.
Description
Technical field
The utility model relates to a kind of anti-picking device of security door.
Background technology
At present, the anti-picking device of security door is generally realized by the overlap joint of door-plate and doorframe.Two layers of thin iron sheet after the pick-proof limit of this anti-picking device is made up by forward and backward door-plate constitutes, because have the gap between door-plate and the doorframe, and does not connect again, once firmly prying open the outside, the lockset that exposes is destroyed slightly.Another kind of anti-picking device is the position of upper and lower side chain point being brought up to the pick-proof limit, is used for fixing the pick-proof limit, prevents to pry open the pick-proof limit and further destroys main lock again.But the side chain point of this anti-picking device part has through hole, and the saboteur can destroy side chain point earlier and destroy main lock point again, and its pick-proof performance is still not ideal enough.Moreover side chain point lock jack exposes, and influence attractive in appearancely, and manufacturing process bothers.
Summary of the invention
The purpose of this utility model is: the anti-picking device that a kind of pick-proof performance ideal, easily manufactured security door are provided.
The utility model is achieved through the following technical solutions:
A kind of anti-picking device of security door, a side of Men Tiyu doorframe links to each other by hinge, and the opposite side of door body and doorframe is provided with main lock point and side chain point; The door body is provided with the pick-proof flanging, and doorframe is provided with and the corresponding groove of pick-proof flanging; Link to each other by interlinked mechanism between main lock point and side chain point.Described side chain point and main lock point are provided with before and after vertical direction, one side of doorframe upper groove is provided with side chain point lockhole in side chain point corresponding position, the pick-proof flanging of door body comprises continuous interior side edgefold and outer side edgefold, in the lockhole of side chain point on the pick-proof flanging only is located on the side edgefold.Because the side chain point is wrapped in the pick-proof flanging, even the saboteur is mashed side chain point and the main lock point of also can't destroying of pick-proof flanging sled, because side chain point is in the concealment state fully in motion process, all can not see from longitudinal and transverse direction and the position at its place to make that the utility model pick-proof performance is very good.Moreover because side chain point and main lock point are provided with before and after vertical direction, it has further improved the pick-proof performance.
In the utility model, the pick-proof flanging of described door body is the trapezoidal shape of chamfer.It can do the crack between a door and its frame gap less not influencing under the prerequisite of body unlatching.
In the utility model, be provided with stiffener in the described door body pick-proof flanging.It can further improve the pick-proof performance.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model cross section enlarged diagram-for more clearly demonstrating the utility model, side chain point and main lock point are illustrated on the same drawing.
The specific embodiment
In conjunction with Fig. 1, shown in Figure 2, the anti-picking device of present embodiment security door, door body 1 links to each other by hinge 3 with a side of doorframe 2, and the opposite side of door body and doorframe is provided with main lock point 4 and side chain point 5; The door body is provided with pick-proof flanging 6, and the pick-proof flanging of door body is the trapezoidal shape of chamfer.Doorframe is provided with and the corresponding groove 7 of pick-proof flanging; Link to each other by interlinked mechanism 8 between main lock point and side chain point.Side chain point 5 and main lock point 4 are provided with before and after vertical direction, one side of doorframe upper groove is provided with side chain point lockhole 9 in side chain point corresponding position, the pick-proof flanging of door body comprises continuous interior side edgefold 10 and outer side edgefold 11, in the lockhole 12 of side chain point on the pick-proof flanging only is located on the side edgefold 10.Be provided with stiffener 13 in the door body pick-proof flanging.
Present embodiment is because side chain point and main lock point are provided with before and after vertical direction, and the side chain point is wrapped in the pick-proof flanging, makes that the utility model pick-proof performance is very good.
