Detailed Description

The embodiments described below with reference to the drawings are illustrative only and should not be construed as limiting the invention.

As shown in fig. 1 to 4, an embodiment of the present invention provides a top and bottom hook opening and closing assembly of a security door, including:

bottom plate 1, in the lock box was located to bottom plate 1, main spring bolt assembly, vice spring bolt assembly and world hook assembly all set up on bottom plate 1, because the main innovation point of this application lies in on the control to the world hook, so hidden some other irrelevant parts such as main spring bolt assembly, vice spring bolt assembly in the picture, can not carry out too much repeated description to these irrelevant parts yet, bottom plate 1 is the concave two guide ways 2 that are equipped with, two guide way 2 sets up along the vertical direction interval syntropy, and the vertical direction in this application is perpendicular to ground direction, and guide way 2 is waist type pore structure.

A top-to-bottom hook opening and closing assembly comprising a base plate 3, an L-shaped pull block 4, and a drive unit, wherein:

the base plate 3 is fixed in on the bottom plate 1, be equipped with in the base plate 3 and hold the chamber, hold the chamber in the top and the bottom of base plate 3 form uncovered, it has guiding groove 5 to run through on the base plate 3, guiding groove 5 is equipped with two, two guiding groove 5 symmetry sets up, forms positive eight shape structure, two guiding groove 5 and two guiding groove 2 one-to-one.

The L-shaped pull block 4 is accommodated in the accommodating cavity, two L-shaped pull blocks 4 are arranged, two L-shaped pull blocks 4 are arranged in a deviating mode, the long edge section of the L-shaped pull block 4 extends out of the opening of the accommodating cavity, the tail end of the long edge section of the L-shaped pull block 4 is connected with a top-bottom hook, the top-bottom hook is used for pulling a door bolt at the upper position and the lower position of a door, the bottom surface of the short edge section of the L-shaped pull block 4 is convexly provided with a guide block 6, the guide block 6 penetrates through the guide groove 5 and then extends into the guide groove 2, the top surface of the short edge section of the L-shaped pull block 4 is convexly provided with a connecting block 17, when the L-shaped pull block 4 moves from the mutually close parts of the regular eight-shaped structures to the mutually far parts of the regular eight-shaped structures, the L-shaped pull blocks 4 are far away from each other, so that the top-bottom hook is extended, the door bolt is locked and then extends out, and the door bolt is driven, and when the L-shaped pull block 4 moves from the mutually far parts of the.
