Description

Technical Field

[0001] This utility model relates to the field of door core technology, and in particular to an intelligent fireproof door core. Background Technology

[0002] Fire doors are doors that can meet the requirements of fire resistance stability, integrity, and heat insulation within a certain period of time. Installed on fire-resistant partitions with a certain degree of fire resistance, fire doors can prevent the spread of fire for a certain period, ensuring the evacuation of personnel. Fire doors are a key line of defense for building fire safety, playing a crucial role in critical moments. The materials used in fire doors undergo strict selection and special treatment, possessing excellent fire resistance performance. In addition to the functions of ordinary doors, fire doors can effectively block the spread of fire and smoke. In the event of a fire, fire doors can buy valuable time for personnel evacuation, while also protecting fire-fighting facilities and building structures, reducing fire losses.

[0003] Fire door lock cylinders are critical components of fire doors, ensuring their proper opening and closing and maintaining their integrity during a fire. Made from special high-temperature resistant materials, their internal structure is meticulously designed to resist high-temperature deformation. Fire door lock cylinders must not only fulfill everyday anti-theft functions but also maintain stable operation for extended periods in high-temperature fire environments. While ordinary lock cylinders may fail due to heat during a fire, preventing the door from opening and closing properly, fire door lock cylinders can ensure smooth opening and closing within a specified fire resistance time, facilitating evacuation and preventing the spread of flames and smoke through door gaps, thus buying valuable time for evacuation and fire rescue. However, current fire door lock cylinder lubrication methods only apply surface lubricant, failing to lubricate the internal components. This leads to friction and wear between internal parts, shortening the lock cylinder's lifespan, increasing replacement costs, and causing metal debris to accumulate inside, leading to lock cylinder malfunctions and severely weakening the fire door's protective function in fire safety. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an intelligent fireproof door core, which aims to improve the problem that in the existing technology, adding lubricating oil to the fireproof door core can only be applied to the surface and cannot lubricate the inside of the lock core, resulting in friction and wear between internal parts, shortening the service life of the lock core, and increasing replacement costs.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an intelligent fireproof door core, comprising a shell, a locking block rotatably connected to the outer wall of the shell, a limiting block fixedly connected to the outer wall of the locking block, a side plate fixedly connected to the outer wall of the locking block, a rotating tooth rotatably connected between adjacent side plates, a rotating column rotatably connected to the outer wall of the shell, a ratchet fixedly connected to one end of the rotating column, a single gear fixedly connected to the outer wall of the rotating column, multiple auxiliary blocks fixedly connected to the outer wall of the shell, a pressing column slidably connected to the inner wall of the auxiliary blocks, a fixing tooth fixedly connected to the outer wall of the pressing column, an oil storage box provided at the top of the shell, a pump head provided at one end of the oil storage box, an oil delivery pipe provided on the outer wall of the locking block, a triangular block fixedly connected to the top of the pressing column, and an automatic locking mechanism provided on the bottom surface of the shell for automatic locking in case of fire.

[0006] As a further description of the above technical solution:

[0007] The automatic locking mechanism includes a backup battery, the top surface of which is fixedly connected to the top surface of the outer casing.

A sleeve is fixedly connected to the bottom surface of the outer casing, and a thermosensitive material is provided on the inner wall of the sleeve. A conductive rod is slidably connected to the inner wall of the sleeve, and a terminal is fixedly connected to the outer wall of the conductive rod. A fixed contact is fixedly connected to the center of the bottom surface of the outer casing.

[0008] As a further description of the above technical solution:

[0009] The outer wall of the housing is provided with a heat insulation shell, and an installation plate is fixedly connected to the outer wall of the housing.

[0010] As a further description of the above technical solution:

[0011] A slanted tongue is provided on the upper middle part of the right outer wall of the housing, and a locking tongue is provided on the lower middle part of the right outer wall of the housing.

[0012] As a further description of the above technical solution:

[0013] The outer front wall of the housing is provided with a lock hole, and a buzzer is fixedly connected to the upper end of the outer wall of the mounting plate.

[0014] As a further description of the above technical solution:

[0015] A power supply is located on the right outer wall of the housing, and a controller is located at the bottom of the power supply.

[0016] As a further description of the above technical solution:

[0017] A spring is provided between the adjacent limit block and the rotating tooth, an oil injection hole is provided at the top of the oil storage box, a tension spring is provided at the bottom of the extrusion column, and the other end of the tension spring is fixedly connected to the outer shell through a fixing block.

[0019] The outer wall of the heat insulation shell is provided with a door, a face recognition probe is provided on the upper front side of the door, and an alarm is provided on the upper middle front side of the door.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, rotating the locking block controls the extension and retraction of the latch. When the locking block is rotated, the rotating teeth press the ratchet, causing the ratchet to rotate. A rotating column is fixedly connected to the middle of the ratchet, and the rotating column is fixedly connected to the outer shell. The ratchet is fixed on the rotating column, that is, the rotating column rotates. When the locking block is reset, since the spring is fixed between the limiting block and the rotating teeth, the spring pulls the rotating teeth upward, causing the rotating teeth to reset as well. When the door is opened multiple times, that is, the locking block is rotated multiple times, the rotating teeth push the ratchet to rotate multiple times. When the ratchet rotates once, the single gear also rotates once. The teeth on the single gear push the fixed teeth on the extrusion column, causing the extrusion column to move upward. The triangular block at the top of the extrusion column engages with the bottom surface of the pump head. The pump head presses to the left, pumping the lubricating oil from the oil storage box into the interior of the outer shell through the oil delivery pipe to lubricate the interior of the outer shell, thus achieving automatic lubrication after multiple unlocking and unlocking.

[0022] 2. In this utility model, the heat-sensitive material expands when heated. When the temperature rises due to a fire, the heat-sensitive material expands and pushes the conductive rod. The conductive rod contacts the fixed contact. The negative terminal of the backup battery is connected to the fixed contact through a wire, and the positive terminal is connected to the telescopic rod. The telescopic rod is connected to the terminal block on the outer wall of the conductive rod. When the conductive rod contacts the fixed contact, the telescopic rod is energized. The telescopic rod pushes the locking block to achieve automatic locking in case of fire. When the telescopic rod is energized, it can communicate with the controller to activate the sound and light alarm and the facial recognition door opening and closing function.

[0044] The thermal material 208 expands when heated. When the temperature rises during a fire, the thermal material 208 expands and pushes the conductive rod 203. The conductive rod 203 contacts the fixed contact 202. The negative terminal of the backup battery 201 is connected to the fixed contact 202 through a wire, and the positive terminal is connected to the telescopic rod 205. The telescopic rod 205 is connected to the terminal 207 on the outer wall of the conductive rod 203. When the conductive rod 203 contacts the fixed contact 202, the telescopic rod 205 is energized. The telescopic rod 205 pushes the locking block 206 to achieve automatic locking in case of fire. When the telescopic rod 205 is energized, it can communicate with the controller 23 to activate the audible and visual alarm and the facial recognition door opening and closing function.
