Abstract

The utility model discloses a three directional theft-proof door lock, comprising a lock shell, a group of lock cores and deflector rod ands, and a transversal bolt which is controlled by the group of lock cores and deflector rods. The utility model is characterized in that the three directional theft-proof door lock also comprises another group of lock cores and deflector rods, the lock shell is provided with a transversal tongue plate which corresponds to the group of deflector rods and is provided with a gear rack, the lock shell is also provided with a gear engaged with the transversal tongue plate, and two blocks of longitudinal upper and lower drawplates with gear racks are engaged in parallel on the gear. Owing to the transmission action of the transversal tongue with the gear rack and the gear, simultaneously extending out the upper and the lower drawplates and recessing the upper and the lower drawplates into the lock shell are realized. The three directional theft-proof door lock is favorable in confidentiality and flexible in opening, and the main tongue and the auxiliary tongues are strong in resisting static pressure.

Description

The three-dimensional safe-guard door lock

The utility model relates to a kind of three-dimensional lock.

Existing three-dimensional door lock all is made up of one group of tapered end, and confidentiality is poor, a little less than the anti-static pressure of main tongue and labella, and complex structure, open dumb.

The purpose of this utility model is to provide a kind of good confidentiality, open flexible and main tongue and the anti-static pressure of labella strong, and a kind of three-dimensional safe-guard door lock of three directions of locking door simultaneously.

For achieving the above object, the utility model adopts following scheme:

A kind of three-dimensional safe-guard door lock includes lock housing.One group of lock core and dead man and by the horizontal dead bolt of this group lock core and dead man control, it is characterized in that also including another group lock core and dead man, be equipped with corresponding on the lock housing and be provided with the horizontal hyoplastron of tooth bar with this group dead man, two parallel being engaged on the gear of vertical upper and lower arm-tie that have tooth bar also are housed on the lock housing and this horizontal hyoplastron meshed gears.

Three-dimensional safe-guard door lock described in the utility model because the band horizontal hyoplastron of tooth bar and the gearing of gear, realized horizontal hyoplastron and upper and lower arm-tie stretch out with retraction synchronously; In addition, this locks good confidentiality, open flexible and main tongue and the anti-static pressure of labella strong,

Below in conjunction with accompanying drawing structure of the present utility model is elaborated.

Fig. 1: structural representation of the present utility model;

Fig. 2: lateral view of the present utility model.

Three-dimensional safe-guard door lock described in the utility model includes lock housing 1, one group of lock core 2 and dead man 3 and by one group of horizontal dead bolt 4,5 of this group lock core 2 and dead man 3 controls; In addition, this door lock also includes another group lock core 6 and dead man 7, be equipped with corresponding on the lock housing 1 and be provided with the horizontal hyoplastron 8 of involute teeth with this group lock core 6 and dead man 7, also be equipped with on the lock housing 1 and these horizontal hyoplastron 8 meshed gears 9, lock housing is provided with two blocks of band tooth bars and the parallel vertical upper and lower arm-tie 10,11 that is engaged in gear 9.

Stirring lock core 2 drives driving levers 3 and can control horizontal dead bolt 4,5 and stretch out or retraction lock housing 1; Stir lock core 6 and drive dead mans 7 counterclockwise or when turning clockwise, driving horizontal hyoplastron 8 stretches out or retraction lock housing 1, and by stirring last arm-tie 10, lower pulling plate 11 with gears engaged with horizontal hyoplastron 8 meshed gears 9, make them do upper and lower motion, thereby form horizontal hyoplastron 8, go up arm-tie 10, three directions of lower pulling plate 11 are stretched out or being synchronized with the movement of retraction lock housing.Lock core 6 drives dead mans 7 counterclockwise or when turning clockwise, the side's of driving hyoplastron 10,11 stretches out or retraction lock housing 1.
