DETAILED DESCRIPTION

[0019] like Figure 1-2As shown, an armored door that is easy to assemble includes a transverse frame 1 and a side frame 2. The transverse frame 1 is symmetrically distributed up and down, and the side frames 2 are symmetrically distributed left and right. The side frames 2 are slidably inserted into the transverse frame 1. The transverse frame 1 and the side frames 2 are bolted together by a right-angle connector 17. A mother door 3 and a sub-door 4 are movably installed between the transverse frame 1 and the side frames 2. The inner part of the sub-door 4 is a cavity setting, and also includes a positioning component, which is arranged in the sub-door 4.

[0020] like Figure 1-4 As shown, in order to quickly complete the locking work of the sub-door 4, the positioning assembly includes a worm 5, a two-way screw 6, an adjusting cylinder 8 and a plug column 9. One end of the worm 5 is rotatably connected to the sub-door 4, and the other end of the worm 5 passes through the sub-door 4 and is rotatably connected thereto. One end of the worm 5 is fixedly connected to an adjusting handle 10, and a symmetrically arranged fixing block 11 is fixedly connected inside the sub-door 4. The two-way screw 6 passes through the fixing block 11 and is rotatably connected thereto. The adjusting cylinder 8 passes through the two-way screw 6 and is threadedly connected thereto. The adjusting cylinder 8 is symmetrically distributed. The plug column 9 is fixedly connected to one end of the adjusting cylinder 8, and one end of the plug column 9 passes through the sub-door 4 and is slidably connected thereto. The sub-door 4 is provided with two symmetrically distributed limiting grooves 12, and the limiting grooves 12 are arranged in a long strip shape. The outer side wall of the adjusting cylinder 8 is fixedly connected to a symmetrically distributed limiting block 13, and the limiting block 13 is slidably arranged inside the limiting groove 12. A worm wheel 14 is fixedly connected to the middle position of the two-way screw 6, and the worm 5 and the worm wheel 14 are meshed.

[0021] The transverse frame 1 is provided with positioning holes 15 symmetrically distributed on the left and right, the transverse frame 1 is provided with positioning grooves 16, the positioning grooves 16 are adapted to the plug posts 9, and the side frames 2 are provided with mounting holes 7, which are symmetrically distributed up and down.

[0022] During specific use, first, the two sets of transverse frames 1 are fixed and installed by bolts passing through the positioning holes 15, and then the side frames 2 are inserted into the transverse frames 1, and then the side frames 2 are installed and fixed by bolts passing through the mounting holes 7. At this time, the installation of the entire door frame is completed. When locking the sub-door 4, the adjusting handle 10 is turned, and the rotation of the worm 5 drives the worm wheel 14 and the bidirectional screw 6 to rotate. The adjusting cylinders 8 at both ends of the bidirectional screw 6 drive the plug column 9 to move under the limiting and guiding action of the limit block 13 and the limit groove 12, until the plug column 9 is inserted into the positioning groove 16 to complete the locking of the sub-door 4. The operation is simple.
