Description

Technical Field

[0001] The utility model relates to the technical field of anti-theft doors, in particular to an anti-theft door with good sound insulation. Background Art

[0002] Equipped with anti-theft locks, it can resist abnormal opening under certain conditions within a certain period of time, has certain safety protection performance and meets the corresponding anti-theft security level. Anti-theft doors can be made of different materials, but only those that meet the standard inspection and obtain the security product production certificate can be called anti-theft doors. The common anti-theft doors on the market currently have inner door panels made of rock wool and honeycomb paper, and there is no sound insulation material at the joints between the door frame and the wall. Therefore, it is necessary to use anti-theft doors with good sound insulation.

[0003] For example, a sound-proof anti-theft door with patent application number 202321506109.3 includes an inner door frame, an outer door frame is integrally formed on one side of the inner door frame, an outer door panel is movably installed on the side of the outer door frame away from the inner door frame through a hinge, an inner door panel is integrally formed on the side of the outer door panel close to the outer door frame, and an electronic fingerprint lock is provided on the side of the inner door panel away from the hinge. The inner door frame and the outer door frame are installed in designated door frame grooves, and then the inner door frame and the outer door frame are fixed to the door frame grooves with anchor bolts, and then an injection molding tool is used to pour the filling sound-absorbing material from the position of the injection pipe, and then enter the filling groove along the opening, the sound-absorbing material passes through a number of through grooves until the filling groove is densely filled, thereby improving the sound insulation of the installation seam of the anti-theft door.

[0004] However, during the use of the above-mentioned equipment, due to the setting of its internal and external door frames, the sound-absorbing material is pressed into the inside of the anti-theft door when leaving the factory, and is not easy to disassemble and replace. The anti-theft door has poor sound insulation effect after long-term use, which reduces the usage restrictions. Therefore, in response to this situation, we propose a more convenient and practical anti-theft door with good sound insulation to meet the usage needs. Utility Model Content
