Title: Door Bolt Lock Structure

Description:
FIELD OF THE INVENTION 
     The present invention relates to a door bolt lock structure by which the head extends in different distances based on using requirements by selectively aligning the threaded orifice of the head with the first locating orifice or the second locating orifice of the slide plate easily. 
     BACKGROUND OF THE INVENTION 
     A door frame contains a groove defined thereon and configured to receive a head a conventional door bolt lock, thus locking a door. 
     However, the head cannot extend in different distances based on using requirements. 
     The present invention has arisen to mitigate and/or obviate the afore-described disadvantages. 
     SUMMARY OF THE INVENTION 
     The primary aspect of the present invention is to provide a door bolt lock structure by which the head extends in different distances based on using requirements by selectively aligning the threaded orifice of the head with the first locating orifice or the second locating orifice of the slide plate easily. 
     To achieve above-mentioned aspect, a door bolt lock structure provided by the present invention contains: a casing, a drive element, a slide plate, and a head. 
     The casing includes a cavity defined therein, and the case includes a locking orifice formed on a predetermined position of a first end thereof. The drive element is accommodated in the cavity of the casing, the drive element includes a lock cylinder mounted on an end thereof, and the drive element includes a control lever extending from a side of the lock cylinder. 
     The slide plate is slidably received in the drive element and includes a holder formed on a first end of the slide plate, a groove defined in the holder so that the control lever of the drive element slides in the groove, a free segment extending from a second end of the slide plate, a first locating orifice defined on a side of the free segment adjacent to the defining portion, and a second locating orifice defined on the side of the free segment away from the defining portion and spaced from the first locating orifice. 
     The head includes a trench configured to receive the free segment of the slide plate, a threaded orifice defined on a top of the head and communicating with the trench. The threaded orifice is selectively aligned with the first locating orifice or the second locating orifice of the slide plate, and a second screw element is inserted through the locking orifice of the casing, the first locating orifice or the second locating orifice, and the threaded orifice of the head so as to adjustably move the head with respect to the slide plate.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     With reference to  FIGS.  1 - 6   , a door bolt lock structure according to a preferred embodiment of the present invention comprises a body A, and the body A includes: 
     a casing  10 , a cavity  12  defined in the casing  10 , a locking orifice  11  formed on a predetermined position of a first end of the casing  10 , a connection segment  13  formed on a second end of the casing  10 , multiple apertures  14  defined on multiple predetermined positions of the connection segment  13 , a cap  15  covered on the connection segment  13 , multiple fixing portions  16  formed on the cap  15  and corresponding to the multiple apertures  14 , multiple first screw elements  17  inserted through the multiple apertures  14  and the multiple fixing portions  16  so as to connect the cap  15  with the connection segment  13  of the casing  10 ; wherein the casing  10  further includes a stop sheet  60 , and the stop sheet  60  has a through orifice  61  passing through a center of the stop sheet  60  and aligning with the cavity  12  of the casing  10 ; 
     a drive element  30  accommodated in the cavity  12  of the casing  10 , the drive element  30  including a lock cylinder  31  mounted on an end of the drive element  30 , and the drive element  30  including a control lever  32  extending from a side of the lock cylinder  31 ; 
     a slide plate  40  slidably received in the drive element  30  and including a holder  41  formed on a first end of the slide plate  40 , a defining portion  43  formed opposite to the holder  21 , a groove  42  defined in the holder  41  so that the control lever  32  of the drive element  30  slides in the groove  42 , a free segment  46  extending from a second end of the slide plate  40 , a first locating orifice  44  defined on a side of the free segment  46  adjacent to the defining portion  43 , and a second locating orifice  45  defined on the side of the free segment  46  away from the defining portion  43  and spaced from the first locating orifice  44 ; and a head  50  including a trench  51  configured to receive the free segment  46  of the slide plate  40 , a threaded orifice  52  defined on a top of the head  50  and communicating with the trench  51 , wherein the threaded orifice  52  is selectively aligned with the first locating orifice  44  or the second locating orifice  45  of the slide plate  40 , and a second screw element  20  is inserted through the locking orifice  11  of the casing  10 , the first locating orifice  44  or the second locating orifice  45 , and the threaded orifice  52  of the head  50  so as to adjustably move the head  50  with respect to the slide plate  40 . 
     Referring to  FIGS.  1 - 3   , the threaded orifice  52  of the head  50  is connected with the first locating orifice  44  of the slide plate  40  so that the head  50  extends in a first distance. As shown in  FIGS.  4 - 6   , the threaded orifice  52  of the head  50  is connected with the second locating orifice  45  of the slide plate  40  so that the head  50  extends in a second distance, wherein the first distance is less than the second distance. 
     Accordingly, the head  50  extends in different distances based on using requirements by selectively aligning the threaded orifice  52  of the head  50  with the first locating orifice  44  or the second locating orifice  45  of the slide plate  40  easily. 
     While the preferred embodiments of the invention have been set forth for the purpose of disclosure, modifications of the disclosed embodiments of the invention and other embodiments thereof may occur to those skilled in the art. Accordingly, the appended claims are intended to cover all embodiments which do not depart from the spirit and scope of the invention.
