Abstract
A spirally-latched burglarproof door comprises a gate wing, a door-frame and a door lock. Indoor and outdoor cavities of the door lock are provided with a tooth gearing mechanism; and inside the gate wing, a movable bolt-nut the mechanism is provided; a driven gear on the tooth gearing mechanism is fixed to connect with a bolt guide sleeve on the bolt-nut mechanism. The burglarproof door adopts a spiral three-point latch mode in upper, left-medium and lower positions (four-point latch mode if necessary). The gate wing is firmly connected with the door-frame with considerable lever-proof and damage-proof capacity. The utility model has the advantages of simple manufacturing and convenient installation and positioning; as well as effectively saving gate wing materials and lowering cost; light manual operation and high durability; broad utilization scope and being suitable to be installed in cities or villages and adapting for safe box, therefore universal expansion and utilization values can be ensured.
Description
Technical field
The utility model relates to the home-use twist-lock of a kind of resident to be prevented forcing open the door.
Background technology
Original house mostly is two kinds of forms with anti-forcing open the door, and a kind of is the anti-of five safety locks directly to be installed force open the door, and its locking form is simple, and easy installation and removal is easily extractd tapered end or by the human simple tool door leaf separated with doorframe by the people in the use.Then to be that 3 slide locks in upper, middle and lower are anti-force open the door another kind, and tapered end is equally easily extractd by the people, also easily prized by the human crowbar to make the door leaf distortion and separate with doorframe.These two kinds of locksets all are the reciprocal straight line transmissions of simple form, dead bolt can only directly advance or directly move back, the forward and back journey is shorter, belong to smooth cooperation locking, even increase substantially door leaf intensity, can not effectively improve the anti-whole stability of forcing open the door, so that, making the anti-forfeiture of forcing open the door effectively stop the function of isolating the illegal discrepancy of stranger in that utilized external force to make the time spent door leaf by the people easily separated with doorframe.
Summary of the invention
The purpose of this utility model is exactly for overcoming the existing anti-defective of forcing open the door and existing, adopt 3 the locking forms in spiral upper, middle and lower, and by the gear drive of high pass efficient, a kind of efficient, light, durable, reliable twist-lock is anti-forces open the door thereby provide.
Anti-the forcing open the door of twist-lock comprises door leaf, doorframe and door lock, establish gear drive between the inside and outside tapered end of door lock, dress mobile screw nut body in the door leaf, its screw rod and can with the supporting connection of corresponding nut in the doorframe, the screw rod pilot sleeve of the driven gear of gear drive and bolt and nut mechanism is for fixedlying connected.
Gear drive comprises gear housing, and the drive bevel gear in the casing and three driven wheels of differential that are engaged with.Gear housing then is fixed in door leaf Inner door lock place.
The door lock cover is threaded with the gear housing employing and by dowel fixes, lock core is concentric with drive bevel gear, and latter's endoporus adapts with the lock core endoporus and with key shape.
The mobile screw nut body comprises screw rod pilot sleeve, mobile screw, door leaf nut and doorframe nut, and the door leaf nut joins with the doorframe nut is corresponding, and pitch, direction are all identical.
Screw rod fairlead barrel is processed with elongated slot vertically, is slidingly matched with the set pin of screw shaft one side, and screw rod can move axially along the sleeve elongated slot with pin and enter or withdraw from nut.
Adopt on the spiral bikini, in the left side, (in case of necessity also can 4 points) locking form down, can significantly improve the degree that is connected firmly of door leaf and doorframe, even by jack doorframe is separated with door leaf by the people.Tapered end makes the people wait instrument that the tapered end extraction is removed by embracing card because employing is threaded with door leaf internal tooth roller box.
This utility model latch-up structure has significant pick-proof, anti-damage ability; Make simply, installing and locating is convenient; Can effectively save the door leaf material, reduce cost; Manual operation is light, and is durable in use; The scope of application is wide, and town and country all can be installed at home, and is suitable for the safety cabinet use, and general application value is arranged.
