The present invention relates to a control structure of a door lock which contains a motor configured to drive a deadbolt to move outward or retract backward with respect to an open segment of a body easily, and the control structure contains a first cap and a second cap which is integrally formed respectively so as to obtain structural reinforcement to avoid easy deformation, wherein the control structure contains the deadbolt pushed forward by a latch.
A conventional door lock is connected by several components, so it is operated badly after a period of using time. Furthermore, the conventional deadbolt is deformed easily after being hit.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.
The primary object of the present invention is to provide a control structure of a door lock which contains a motor configured to drive a deadbolt to move outward or retract backward with respect to an open segment of a body easily.
Further object of the present invention is to provide a control structure of a door lock which contains a first cap and a second cap which is integrally formed respectively so as to obtain structural reinforcement to avoid easy deformation.
Another object of the present invention is to provide a control structure of a door lock which contains the deadbolt pushed forward by a latch.
To obtain above-mentioned aspect, a control structure of a door lock provided by the present invention contains: a body, a slidable partition, a motor, a slide cylinder, a deadbolt, a latch, a first resilient element, and a second resilient element.
The body includes a first cap, a second cap, an open segment, a close segment, a drive space, a holder, a groove, and an abutting post.
The slidable partition is accommodated in the body, and the slidable partition includes a slot, two spaced first driving extensions, a second driving extension, a through hole, two symmetrical hooks, a seat, a drive orifice, a first paw, a second paw, and a shaft. The shaft has a hole corresponding to the drive orifice.
The motor is accommodated in the holder of the body, the motor includes a guide rod, and a side wall of the motor is positioned by the abutting post of the body.
The slide cylinder is received in the drive space of the body. The slide cylinder includes an opening and a fixing segment. The fixing segment has a fence, a guide orifice, a trench, two troughs, at least one horizontal trench, a first positioning segment, and a first locating protrusion.
The deadbolt is fixed in the body and is movably received in the opening of the slide cylinder. The deadbolt includes a locking segment, a chamber.
The latch is accommodated in the notch of the deadbolt, and the latch includes a lock fringe and a second location protrusion.
A first end of the first resilient element is positioned on the second positioning segment of the slide cylinder, and a second end of the first resilient element is fixed on the first positioning segment of the deadbolt.
A first end of the second resilient element is positioned on the first locating protrusion of the slide cylinder, and a second end of the second resilient element is fixed on the second location protrusion of the latch.
The present invention will be clearer from the following description when viewed together with the accompanying drawings, which show, for purpose of illustrations only, a preferred embodiment in accordance with the present invention.
