Detailed Description

The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, and the scope of the present invention can be more clearly and clearly defined.

Referring to fig. 1 to 3, a hinge connecting structure for a front plate and a rear plate of a security door comprises an upper hinge 4, a lower hinge 7 and a pressure bearing 5, wherein the upper hinge 4, the lower hinge 7 and the pressure bearing 5 are sequentially stacked from top to bottom, a movable groove 8 is arranged in the upper hinge 4, the movable groove 8 is communicated with the outer side of the upper hinge 4, a fixed groove 9 is arranged in the lower hinge 7, the fixed groove 9 is communicated with the outer side of the lower hinge 7, and a core rod 3 is arranged on the inner side of the movable groove 8, the fixed groove 9 and the inner side of the pressure bearing 5.

The top end of the upper hinge 4 is provided with an upper through hole 1 for the thin rod to pass through. The diameter of the upper through hole 1 is smaller than that of the movable groove 8, so that the core rod 3 is prevented from being separated from the top end of the movable groove 8. And the inner hexagonal countersunk head screw 2 is also connected to the upper part of the core rod 3 on the movable groove 8, so that the lower hinge 7 is prevented from being released after the core rod 3 moves upwards. The upper hinge 7 is provided with a limiting groove 6 communicated with the fixing groove 9 and positioned on the lower end side of the lower hinge 7, and the lower end side of the limiting groove 6 and positioned at the bottom end of the lower hinge 7 are provided with a lower through hole 10 communicated with the limiting groove 6, so that the mandrel 3 can not move downwards in the fixing groove 9. The diameter ratio of spacing groove 6 is less than fixed slot 9 diameter, and lower through-hole 10 diameter ratio is less than spacing groove 6 diameter, and plug 3 can't move down again in fixed slot 9, and the slim rod passes through easily. The upper end and the lower end of the core rod 3 are of chamfer structures, so that the installation is more convenient.

In this embodiment, the anti-theft door plate is welded and fixed with the upper hinge 4 or formed at one time, the anti-theft door frame is welded and fixed with the lower hinge 7 or formed at one time, when in installation, firstly the anti-theft door frame is fixed, then the core rod 3 and the pressure bearing 5 are knocked into the movable groove 8 in the upper hinge 4 from bottom to top by a thin rod as shown in fig. 2, then the upper hinge 4, the pressure bearing 5 and the core rod 3 are sleeved into the upper end of the lower hinge 7 transversely, at this time, if the bottom end of the core rod 3 is exposed out of the lower end surface of the pressure bearing 5, after the upper hinge 4 is placed on the lower hinge 7, the thin rod is jacked up from the lower through hole 10 to make the bottom end of the core rod 3 higher than the lower end surface of the pressure bearing 5, at this time, the core rod 3 is positioned inside the upper hinge 4 and the pressure bearing 5, then the upper hinge 4, the pressure bearing 5 and the lower, and (3) moving the core rod 3 downwards to the middle of the upper hinge 4, the pressure bearing 5 and the lower hinge 7, wherein the upper end of the upper hinge 4 is provided with a threaded hole for screwing the inner hexagonal countersunk head screw 2, and finally, the inner hexagonal countersunk head screw 2 is screwed at the upper hinge 4 in a threaded manner, so that the end part of the inner hexagonal countersunk head screw extends into the movable groove 8 and is positioned at the upper end of the core rod 3.

The core rod 3 is in clearance fit with the lower hinge 7 and the pressure bearing 5, and is in clearance fit with the upper hinge 4, which can be of an opposite structure, or the core rod 3 is in clearance fit with the lower hinge 7, the pressure bearing 5 and the upper hinge 4, as long as the upper hinge 4 and the lower hinge 7 can rotate relatively.

The above description is only the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that are not thought of through the creative work should be covered by the present invention.
