anti-theft door

Define the door equipped with anti-theft lock, which can resist abnormal opening under certain conditions within a certain period of time, has certain security protection performance and meets the corresponding anti-theft security level. According to the classification, there are four levels of anti-theft security, namely, A, B, C and D, which decrease from high to low. Intelligence is mainly reflected in the intelligence of its key components (locks), including various electronic anti-theft locks that have been widely used, such as fingerprints, passwords, IC card locks, etc. With the progress of technology, in addition to replacing traditional mechanical locks with intelligent locks, IoT security doors will also be combined with smart home systems with functions such as security, home appliance control, elderly and child care, and can realize online alarm, video monitoring, data transmission and remote control, which are all manifestations of intelligent security doors.

The standard GB 17565-2007 General Technical Conditions for Security Doors shall be implemented. Technical performance I. Appearance (1) The surface of door frame and door leaf components shall be smooth and clean without obvious dents and mechanical damage. (2) Nameplate signs shall be upright, firm and clear. (3) The anti-theft security door shall be marked with permanent anti-theft security level. (4) The anti-theft security level mark consists of its Chinese code and flat circle, and the Chinese code should be located at the diameter of Φ 25 mm plane circle. (5) It shall be permanently fixed on the upper corner of the inner hinge edge in the form of Song typeface gravure printing, at a height of 1600mm ± 100mm from the ground. 2、 Plate and material (1) Plate material can be steel, stainless steel, steel/wood, copper or other composite materials. (2) The thickness of steel plate a) The door frame shall be 2.00mm, 1.80mm and 1.50mm according to the grade B, C and D of anti-theft safety. b) The thickness of the outer panel and inner panel of the door leaf is expressed in the form of "outer panel/inner panel". According to the anti-theft security level B, C and D, 1.00 mm/1.00 mm, 0.80 mm/0.80 mm and 0.80 mm/0.60 mm shall be selected respectively. c) The thickness of grade A security door shall be selected according to the product design under the condition that it meets the anti damage performance. If the steel plate is selected, its thickness shall not be less than the thickness and allowable deviation requirements of the door frame and door leaf of Class B anti-theft security level. Unqualified low-quality anti-theft doors Unqualified anti-theft doors, as the name implies, fail to meet national standards. Unqualified anti-theft doors have a wide variety in the market, as long as consumers keep a calm attitude. Don't be tempted by low price doors. Select manufacturers with well-known trademarks. Basically, you won't buy unqualified anti-theft doors. Choose the key of the lock cylinder first. The deeper the "teeth" of the key, the more complicated the door lock arrangement is, and the larger the opening is. Second, look at the color of the door lock. The door locks with good quality are all electroplated, with good gloss and smoothness. If the color is dark yellow, it should be copper core. This material is firm, so the protection is good. Third, look at the weight of the door lock. The heavier the weight, the better the quality of the lock cylinder. The more beads in the lock cylinder, the better the protection performance of the lock.
There are many types of security doors in the market today. According to the standard GB25-92 General Technical Conditions for Security Doors issued by the Ministry of Public Security, security doors can be divided into three types: fence type security doors, solid doors and composite doors. The fence type security door is a common security door welded by steel pipes. Its biggest advantages are ventilation, portability, beautiful appearance and relatively low price. The upper part of the anti-theft door is a fence type steel pipe or steel plate, and the lower part is a cold-rolled steel plate, which is locked with multiple locking points to ensure the anti prying ability of the anti-theft door. But the anti-theft effect is not as good as the closed anti-theft door. Solid doors are extruded from cold-rolled steel plates. The door plates are all steel plates. The thickness of steel plates is 1.2 mm and 1.5 mm, with strong impact resistance. The double-layer steel plate of the door leaf is filled with rock wool thermal insulation and fireproof material, which has the functions of anti-theft, fire prevention, heat insulation, sound insulation, etc. General solid anti-theft doors are equipped with cat's eyes, doorbells and other facilities. The compound anti-theft door is composed of a solid door and a fence type anti-theft door, which has the characteristics of anti-theft, fly and mosquito prevention in summer, ventilation and cooling, and warmth and sound insulation in winter. The security doors are classified according to the structural characteristics, mainly including push-pull fence security door, side opening fence security door, plastic embossed security door and multi-functional luxury security door. For ordinary consumers, the security door of residents is mainly a side hung security door. The side hung door is a kind of security door with the largest demand in the market at present. Some standards call this door a household door or an entrance door, indicating that it is a door that distinguishes between indoor and outdoor. Therefore, in addition to anti-theft, it also involves heat preservation, sound insulation, beauty and many other aspects. The side hung door can be formally divided into: ordinary side hung door, door in door, secondary door and compound door. The ordinary side hung door is a closed door with a single leaf. The middle door has the advantages of both a fence door and a side hung door. The outer door is a fence door, and there is a small door behind the fence door. Opening the small door can be used for ventilation of the fence door, and closing the small door can be used as a side hung door. The child and mother doors are generally used in houses with large doorframes for family entry, which can ensure convenient access at ordinary times and also allow large furniture to be moved in conveniently. The compound door is also called one frame and two doors. The front door is a fence door, and the rear door is a closed side hung door.
