Description

Technical Field

[0001] This utility model relates to the field of armored door technology, specifically a quick-installation interface for a fireproof door core for armored doors. Background Technology

[0002] Armored doors (also known as security armored doors) typically need to have both anti-theft and fireproof functions. The door core is the core part, which directly affects the door's protective performance. It can resist violent damage and meet fireproof and heat insulation requirements. In order to greatly improve construction efficiency and maintenance convenience, and simplify the traditional complicated installation process, it is possible to quickly install and fix the door core to the door frame.

[0003] As indicated by announcement number CN214220915U, this door hinge features a quick-release mechanism. The device includes a left locking plate, a right locking plate, a locking sleeve, a spindle, and a hinge plate. The spindle is embedded within the left and right locking plates. The locking sleeve is an open-type sleeve that engages with the spindle at a certain angle. This door hinge offers quick-release functionality, convenient and reliable installation, flexible rotation, and reduced maintenance and tool requirements.

[0004] When the above-mentioned device is in use, the door frame and the door panel need to be connected by hinges so that the door panel can open and close. However, the installation method of the hinges is relatively complicated, which is not conducive to quick installation and disassembly, and is also inconvenient to maintain. Therefore, we propose a quick installation interface for the fireproof door core of armored doors to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide a quick-installation interface for a fireproof door core for armored doors, so as to solve the problems mentioned in the background art that the hinge installation method is relatively complicated, which is not conducive to quick installation and disassembly, and is also inconvenient during maintenance.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a quick-installation interface for a fireproof door core for an armored door, comprising a door core body and a door frame, wherein the door core body is installed inside the door frame;

[0007] Also includes:

[0008] The locking grooves are respectively located on the inner side of the door core body and the inner side of the door frame, and the two sets of locking grooves are interconnected. The locking grooves are movably locked with plug plates, and there are two sets of plug plates that are locked in the two sets of locking grooves respectively. The outer side of the plug plate is provided with a limiting hole. The inner wall of the locking groove is provided with a movable groove, and the movable groove is aligned with the limiting hole. The movable groove is movably installed with a limiting pin. The front end of the limiting pin is an arc surface structure, which is located in the direction in which the plug plate is inserted into the locking groove, and the front end of the limiting pin is movably locked in the limiting hole.

[0009] Preferably, the two plug-in plates are provided with hinges at the ends away from the door frame, and the two plug-in plates are connected and fixed by the hinges. The engagement groove is integrally formed with a limit groove on the side surface near the hinge, and the hinge is movably engaged inside the limit groove.

[0010] Preferably, a spring is installed at the bottom of the inner side of the movable groove, and the spring is attached to the rear end of the limiting post.

[0011] Preferably, a second reset groove is provided inside the door core body on the side near the engaging groove, and a first reset groove is provided inside the door frame on the side near the engaging groove. A connecting rod is installed at the rear end of the limiting post inside the door core body and the door frame, and the connecting rod inside the door core body and the door frame extends into the first reset groove and the second reset groove, respectively.

[0012] Preferably, the first reset plate is movably engaged inside the first reset groove, and all connecting rods inside the first reset groove are connected to the first reset plate. The inner wall of the rear end of the door frame is provided with a through groove, and the through groove communicates with one side of the first reset groove. A pressing rod is provided at the end of the first reset plate near the through groove, and the pressing rod is located inside the through groove.

[0013] Preferably, the second reset slot is movably engaged with the second reset plate, and the connecting rods inside the second reset slot are all connected to the second reset plate. The rear end of the door core body is provided with a sliding groove, and the sliding groove is connected to one end of the second reset slot. The end of the second reset plate near the sliding groove is provided with a lever, and the lever is slidably engaged inside the sliding groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] (1) By setting a locking groove at the connection between the door frame and the door core, two sets of plug-in plates are inserted into the two sets of locking grooves respectively. The plug-in plates are connected and fixed by hinges. A movable limiting post is set on the inner side of the locking groove. When the door core needs to be installed quickly, the plug-in plates are inserted into the two locking grooves respectively. During the insertion process, they contact the arc surface at the front end of the limiting post, causing the limiting post to be pressed backward. Then the limiting post aligns with the round hole on the surface of the plug-in plate. Under the action of the limiting post, the plug-in plate can be fixed in the locking groove, thus completing the quick installation of the door core and improving the installation efficiency.

[0016] (2) When it is necessary to disassemble the door core, on the inside of the door core, by pushing the lever to one side, the limiting pin inside the door core can be moved out of the round hole by the second reset plate. Then, press the pressing rod with the other hand, and move the limiting pin inside the door frame out of the round hole by the first reset plate, so that there is no limiting structure on both sides of the plug plate. Then the plug plate can be quickly taken out, which facilitates the quick disassembly of the door core. The disassembly method is located on the inside of the armored door, so that the operator can only operate from inside the door, preventing unauthorized personnel from disassembling it from the outside of the door. In addition, the disassembly structure requires two hands to operate at the same time to open, and another person needs to pull out the plug plate from the outside of the door to prevent accidental contact.
