Abstract

The utility model relates to a locking device of an antitheft door. A shifting and rotating toothed wheel is arranged on a bottom plate. Two toothed plates with teeth are arranged on both sides of the shifting and rotating toothed wheel, and are engaged with the shifting and rotating toothed wheel. The two toothed plates are respectively provided with a horizontal sliding long hole and an inclined sliding hole. A sliding pin which is fixed to the bottom plate is arranged in the horizontal sliding long hole. The ends of the two toothed plats are connected with a horizontal lock bolt. The upper end and the lower end of the bottom plate are provided with a guiding element, an upper lock bolt and a lower lock bolt penetrate through the guiding elements, and a movable sliding pin on the end part is inserted in the inclined sliding hole. The present invention has the advantage that the door can be locked in four directions; the locking device is matched with a built-in lock with double lock bolts, and eight locking points can be achieved; the safe program is high; the structure is simple; the cost is low.

Description

Lock device for safety door

The utility model belongs to a kind of locking device of security door.

At present, molecule is forced open the door in order to avoid theft, all kinds of security doors are provided on the market, the iron sheet formula arranged with the iron railings bar or the like, but its locking does not partly have great improvement, still take common built-in lock structure, thereby the thief that has reaches the purpose of crossing the threshold and stealing by locking position or the destruction door hinge position of destroying one to two dead bolt.Thereby safe coefficient is high not enough.

The purpose of this utility model provides a kind of novel security door locking device, the locking position of the four direction of a lockable door, and the safe coefficient height, easy to use flexible, and simple in structure, cost is low, is convenient to install.

The purpose of this utility model is achieved in that it includes base plate, dead bolt, and its technical scheme feature is: the base plate center connects to dial by the axle rotation changes gear, and dialling the commentaries on classics gear face has dial hole, inserts lock core shift lever when the built-in lock core is installed; Have two tooth plates of teeth to be loaded on to dial the both sides of changeing gear and with its engagement, the level that all has on two tooth plates slides slotted hole and and tiltedly slides the hole, is fixed on two on the base plate and decides the sliding pin level of being installed on and slide in the slotted hole, the level of tooth plate is slided play the guiding role; The both ends that two tooth plates are opposite connect horizontal dead bolt; The upper and lower side of base plate respectively is fixed with the guide in tape guide hole, dead bolt is threaded onto respectively in the pilot hole of guide up and down, the inner connection of dead bolt moved sliding pin up and down, two moving sliding pins are inserted in two respectively and tiltedly slide in the hole, the level of two tooth plates slides, and drives stretching out and retraction of dead bolt up and down by two moving sliding pins.

Operating principle: the utility model is fixed in the empty stomach of door, the assembling of the built-in lock core driving lever of door is inserted and is dialled in the dial hole that changes gear face.When using key lock, dialling commentaries on classics gear rotation drive two tooth plate levels slides, in horizontal dead bolt lock door both sides, the moving sliding pin of dead bolt tiltedly slides under the effect in hole at two tooth plates up and down, driving up and down, dead bolt stretches out the also position up and down of lock door, during unlatching, key turns in the other direction, and group commentaries on classics gear backward rotation is got final product.

The utility model has the advantages that: the four direction locking position that can realize the locking security door, the safe coefficient height, easy to use flexible, cooperate installation with the double lock tongue built-in lock, can reach eight keyed ends (being two keyed ends of four keyed ends of the present utility model, double lock tongue and two keyed ends of door hinge) of security door, and simple in structure, cost is low, is convenient to install.

Below in conjunction with accompanying drawing embodiment of the present utility model is described further.

Fig. 1 is the utility model concrete structure schematic diagram.

Fig. 2 is the A-A sectional drawing of Fig. 1.

Fig. 3 is that the utility model is installed on a last schematic diagram.

See Fig. 1-3, the utility model concrete structure is as follows: the center of base plate 8 connects to dial by axle 16 changes gear 9, dials the jam 11 of the affixed band dial hole 10 of end face that changes gear 9.Two tooth plates 3 that have teeth 7 are assembled in relatively dials the both sides of changeing gear 9, and with its engagement, the level of having slides slotted hole 5 on two tooth plates 3, each level slides and installs two in the slotted hole 5 and decide sliding pin 15, tooth plate 3 is actively connected on the base plate 8, and plays the horizontally-guided effect.Decide suit roll sleeve 14 on the sliding pin, with the power of reducing friction, respectively have on two tooth plates 3 and tiltedly slide hole 4, the opposite ends of two tooth plates 3 connects horizontal dead bolt 6 by bearing pin 12, the upper and lower side of base plate 8 respectively welds the guide 2 in tape guide hole, and upper and lower dead bolt 1 is installed on respectively in two guides 2, the inner of upper and lower dead bolt 1 is fixedly connected and moves sliding pin 13, suit roll sleeve 14 on the moving sliding pin 13.Two moving sliding pins 13 are inserted into two respectively and tiltedly slide in the hole 5.

Claims

1, a kind of locking device of security door, comprise base plate, dead bolt, it is characterized in that: the base plate center rotates to connect to dial by axle changes gear, dial the commentaries on classics gear face dial hole is arranged, have two tooth plates of teeth to be loaded on to dial the both sides of changeing gear and with its engagement, the level that all has on two tooth plates slides slotted hole and and tiltedly slides the hole, is fixed on two on the base plate and decides the sliding pin level of being installed on and slide in the slotted hole, and the both ends that two tooth plates are opposite connect horizontal dead bolt; The upper and lower side of base plate respectively is fixed with the guide in tape guide hole, and dead bolt is threaded onto respectively in the pilot hole of guide up and down, and inner connection of dead bolt moved sliding pin up and down, and two moving sliding pins are inserted in two respectively and tiltedly slide in the hole.
