Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the description is intended to be illustrative only and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.
Example 1
As shown in the drawings, a temporary iron door anti-theft locking device includes: a rotating rod 1 and a locking block 2 which are respectively arranged on two doors of the iron door;
the rotating rod 1 is a flat rod and comprises a first rod 11 and a second rod 12 which are connected at a fixed angle, and the included angle between the first rod 11 and the second rod 12 is 80 degrees. The tail end of the first rod piece 11 is arranged on the door body 4 through the rotating shaft 3, and the tail end of the second rod piece 12 is provided with a handle 5; the locking block 2 comprises a first limiting plate 21 and a second limiting plate 22 perpendicular to the first limiting plate 21, the second limiting plate 22 is perpendicular to the door body 4, a locking groove 6 is formed between the first limiting plate 21 and the door body 4, and the rod body of the second rod 12 can be buckled in the locking groove 6; when the rod body of the second rod 12 is buckled in the locking groove 6, the included angle of the first rod 11 and the second rod 12 is upward.
When the door body 4 is closed, the maximum distance between the point on the first limit plate 21 and the rotating shaft 3 is m, the distance between the handle 5 and the rotating shaft 3 is n, m is smaller than n, and the difference between m and n is smaller than or equal to 10 mm.
As shown in the figure, if a lawbreaker wants to use a small stick to lift the rotating shaft 3 from the outside of the door to open the door, the two door bodies need to be pushed inward to leave a gap between the two door bodies for the small stick to enter. At this time, as the distance between the two doors increases, the maximum distance m between the point on the first stopper plate 21 and the rotation shaft 3 increases, and the distance n between the handle 5 and the rotation shaft 3 is constant. At this time, if the rotary rod 1 is raised by a small stick, the handle 5 at the end of the second rod 12 is caught by the first stopper plate 21.
Example 2
As shown in the drawings, a further improvement of the temporary iron door anti-theft locking device provided in embodiment 1 is that, unlike embodiment 1, an included angle between the first rod 11 and the second rod 12 is equal to 90 degrees. The rotating shaft 3 is movably mounted in a chute 7 on the door body 4. First limiting plate 21 is kept away from and is installed the locking pole 8 parallel with horizontal limit on the horizontal limit of second limiting plate 22, and locking pole 8 forms the right angle shape draw-in groove with the hypotenuse of first limiting plate 21, and when rotary rod 1 passed through 7 upward movements of spout, handle 5 can block in the draw-in groove. When the rod body of the second rod 12 is snapped into the locking groove 6, the center of gravity of the rotary rod 1 is lower than the center of gravity of the locking piece 2. When the door body 4 is closed, the maximum distance between the point on the locking rod 8 and the rotating shaft 3 is m ', the distance between the handle 5 and the rotating shaft 3 is n, m ' is smaller than n, and the difference between m ' and n is smaller than or equal to 10 mm.
As shown in the figure, if a lawbreaker wants to use a small stick to lift the rotating shaft 3 from the outside of the door to open the door, the two door bodies need to be pushed inward to leave a gap between the two door bodies for the small stick to enter. At this time, as the distance between the two doors increases, the maximum distance m' between the point on the lock lever 8 and the rotation shaft 3 increases, and the distance n between the handle 5 and the rotation shaft 3 is constant. At this moment if will use little rod to pick up rotary rod 1, the handle 5 of the end of second member 12 will be blocked by the hypotenuse formation right angle shape draw-in groove of locking lever 8 and first limiting plate 21, compare in embodiment 1 through the hypotenuse of first limiting plate 21 with handle 5 card end, locking lever 8 forms the right angle shape draw-in groove more effectively with stable with the hypotenuse of first limiting plate 21.
It is to be understood that the above-described embodiments of the present invention are merely illustrative of or explaining the principles of the invention and are not to be construed as limiting the invention. Therefore, any modification, equivalent replacement, improvement and the like made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention. Further, it is intended that the appended claims cover all such variations and modifications as fall within the scope and boundaries of the appended claims or the equivalents of such scope and boundaries.
