The theft-proof door is composed of a door frame, a door leaf, a bolt, a connecting rod, a drive plate, a door with a double bolt, a sector gear, a pinion gear, deadlock points, hinges, a door mirror, a revolving pair, and an auxiliary lock. The door frame is a box-shaped weldment, and the door leaf is a box body formed from the welding after being pressed. The door leaf is connected with the side of the door frame by hinges, the bolt is connected with the drive plate by one connecting rod, the drive plate is connected with the sector gear by one connecting rod and the revolving pair, and the sector gear, the pinion gear, and the door with a double bolt are installed on the door leaf. The utility model has the advantages of simple structure, reasonable process, good locking performance, and low cost.
Description
The utility model relates to a kind of burglary insurance door in the building trade.
At present, along with improving constantly of living standards of the people, the insurance of the property safety of family has become a big problem of society.Epoch timber and iron gate can not satisfy people's living needs far away now, although the security door that has manufactured and designed is multifarious, 6 lockings, 8 lockings etc. are arranged, project organization is unreasonable, locking point relativeness mismate but all exist, pick-proof poor performance, product cost height, manufacturing process complexity, therefore, develop a kind of 9 locking novel anti-theft doors is new problem anxious to be solved always.
The purpose of this utility model be exactly for provide a kind of novel in design unique, manufacturing process is simple, collocation is reasonable, cheap between locking point, the pick-proof performance is good, product strength is high, the hinge good stability, can realize 9 locking novel anti-theft doors of anti-drilling, anticorrosion, fire prevention, insulation, sound insulation function.
The purpose of this utility model is achieved in that whole device is by doorframe, door leaf, dead bolt, connecting rod, dial, two tongue locks, sector gear, pinion, the deadlock point, hinge, peephole, revolute pair, secondary lock is formed, doorframe is a box-shaped weldment, door leaf is the casing that is welded after the compacting, door leaf links together in the side with hinge and doorframe, four in about dead bolt divides and left side, two dead bolts are connected with dial by connecting rod up and down, two dead bolts in left side are connected with dial by connecting rod, connect with revolute pair in the middle of the dead bolt, dial divides two up and down, dial is installed on the door leaf, and dial is used connecting rod respectively up and down, revolute pair is connected with sector gear, and sector gear is installed on the door leaf, two tongue lockings fix on the door leaf left side, pinion is installed on the door leaf, and meshes with sector gear, and secondary lock is installed on the door leaf, and be connected as a single entity with pinion, at three deadlock points of doorframe right side welding, front end inserts the door leaf right side, and peephole is fixed on door leaf top.Main points of the present utility model are its structural shape and locking principle.Its operating principle and method of operating are: at first security door is installed in place door within the walls and and basic fixed.When closing security door, the dead bolt of deadlock point enters in the hole of door leaf side automatically, and key is inserted in two tongue locks, rotate counterclockwise, the dead bolt of two tongue locks is inserted in the frame hole, another key is inserted in the secondary lockhole, rotate counterclockwise, pinion drives sector gear and rotates, drive two connecting rods and move up and down, promote dial and rotate, the dial drivening rod moves, four dead bolts in about making and left side insert in the frame holes, and at this moment whole security door is locked fully.When opening security door, earlier key is inserted in the secondary lockhole, clockwise rotate, pinion drives sector gear and rotates, drivening rod promotes two dials respectively up and down and rotates, and drivening rod moves, and four dead bolts are withdrawn from frame hole, another key is inserted in two tongue lockholes again, clockwise rotate, two dead bolts are extracted out from doorframe, the pulling door leaf, the dead bolt of deadlock point leaves door leaf, makes a complete opening.
Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof.
Fig. 1 is a structural representation of the present utility model.
With reference to accompanying drawing, doorframe 1 is a box-shaped weldment, door leaf 2 is the casings that are welded after the compacting, door leaf 2 usefulness hinges 12 link together with doorframe 1, four in dead bolt and left side about in the of 3 minutes, two dead bolts 3 are connected with dial 5 by connecting rod 10 up and down, connected by revolute pair 14 in the middle of the dead bolt 3, two dead bolts in left side 3 are by connecting rod 4, revolute pair 14 is connected with dial 5, two up and down of dials 5 minutes, be installed in respectively on the door leaf 2, two connecting rods 6 are respectively by revolute pair 14 and dial 5 up and down, sector gear 8 connects, and sector gear 8 is installed on the door leaf 2, and pinion 9 is installed on the door leaf 2, and with sector gear 8 engagement, secondary lock 15 is installed on the door leaf 2, and is connected as a single entity with pinion 9, at three deadlock points 11 of doorframe 1 right side welding, front end inserts door leaf 2 sides, and peephole 13 is fixed on the door leaf 2.
9 locking Anti-theft doors compared with prior art, have that structure uniqueness, technology are simple, the locking point collocation rationally, the pick-proof performance is good, cost is low, will be widely used in the building trade.
