Embodiment Construction

[0007] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0008] A fireproof sealing protection structure of a fireproof lock, which consists of a lock bolt 1, a lock box 2, a fireproof sealing box 3, graphite material 4, a heat-insulation adjustment pad 5, aluminum silicate needle-punched cotton 6, aluminum silicate cotton 7, a lock Head 8, installation screw rod 9, rotating rod 10 are formed, the deadbolt 1 of lockset, lock head 8, rotating rod 10 are installed on the fireproof door in normal way, and a lock box 2 is installed on the outer periphery of dead bolt 1, on the lock box 2 A lock installation hole is punched, and a fireproof sealing box 3 is installed on both sides of the lock box 2. The fireproof sealing box 3 is filled with a fireproof sealing graphite material 4, and heat insulation adjustment pads are arranged on both sides of the outside of the fireproof sealing box 3. 5. The heat insulation...

Abstract

The invention relates to a fireproof lockset, in particular to the fireproof airtight protection structure of the fireproof lockset that is used for the fireproof door, the theftproof door and the door which has the dual fireproof and theftproof function. The invention comprises a bolt, a tapered ned, a tumbler and a lock case which is punched with a mounting hole; two fireproof seal boxes are arranged at both sides of the lock case, a graphite material that is for fireproof sealing purpose is filled inside the fireproof seal box, two heat-insulating adjustment pads which are made of asbestos sheet are arranged at both sides of the graphite material, an aluminum silicate needled wool is filled at the bottom of the lock case and an aluminum silicate wool is filled between the outsides of the lock case and the fireproof seal box and the door. When the temperature is higher than 300 DEG C in fire, the graphite material in the fireproof seal box starts to expand, which fills the clearance between the cylinder of the lockset, the tumbler, a mounting lever and other parts and the lock case, the external heat and smoke cannot enter the inside of the lock case, and thus, the fireproof and heat-insulating and smokeproof effect of a fireproof lock is realized, which guarantees that the fireproof lock is not damaged in fire and can be unlocked normally.

Description

Technical field: [0001] The invention relates to a fireproof lock, in particular to a fireproof seal protection structure for a fireproof door, an antitheft door and a fireproof and antitheft dual-function door. Background technique: [0002] At present, the installation of fire-proof series door-to-locks focuses on adding a lock body protection box with the support function as the main function. When installing the handle and cover plate, it is only for the purpose of ensuring that the surface of the door body does not collapse. Aluminum silicate silk cotton, after a period of use, there will be a large gap due to the rotation of the lock. When a fire occurs, the flame will do great harm to the lock. Smoke will be emitted from the keyhole of the lock, and the temperature will be transmitted to the back of the door through the lock. The fire surface makes people unable to open the lock handle facing the high temperature, and even causes the internal parts of the lock to be d...
