Description
Technical field
The utility model relates to a kind of safe-guard door lock, particularly relates to the bolt device on a kind of this door lock.
Background technology
Safe-guard door lock is used for security door is realized locking, and safe-guard door lock is when realizing the locking of security door, and the locking bolt in the safe-guard door lock is plugged in the locking bolt hole set on the doorframe.The locking bolt overwhelming majority in the existing safe-guard door lock is straight-bar type, and the pick-proof performance of this safe-guard door lock with straight-bar type is not good.For increasing the pick-proof performance of safe-guard door lock, now also occurred a kind of with arc-shaped lock bolt or the hook-shaped safe-guard door lock that colludes tongue, arc-shaped lock bolt or to collude tongue be to move around their pivot in when action, their action is driven by toggle mechanism, toggle mechanism contacts with shifting block on the tapered end, shifting block drives arc-shaped lock bolt by toggle mechanism or the hook tongue reaches the lock body outside, or is fully retracted in the lock body.
The motion amplitude of this hook tongue in lock body is large, need to reserve enough spaces in lock body, so that the hook tongue moves in the mode of rotating.The setting of other transmission mechanism in this inconvenient lock body, therefore, generally speaking, the lock body of this safe-guard door lock is relatively large.And, comparatively complicated for the structure of the transmission mechanism that the hook tongue is rotated.
The utility model content
For overcoming defects, the purpose of this utility model is: a kind of bolt device of door lock is provided, and it is so that the small volume of door lock, and simple in structure.
Reach the technical measures that described purpose is taked: a kind of bolt device of door lock, described door lock has panel, comprise supporting plate, be arranged on the locking bolt of supporting plate end rotationally, the outer end of locking bolt is provided with the convex body that protrudes into its outer peripheral face outside, it is characterized in that, locking bolt is provided with trundle, and trundle is plugged in the saturating groove set on the panel with gap, and groove is dihedral thoroughly.
Described groove is made of the straight trough that is connected as a single entity and skewed slot, and straight trough is along the width setting of panel, and skewed slot is in the setting that tilts of the length direction of panel, and the angle between straight trough and the skewed slot is the obtuse angle.
Described trundle is arc.
The inner end of described locking bolt is provided with jack, and trundle is plugged in the jack.
The locking bolt inner end is provided with pressure head, and the inner end top of pressure head is pressed on the trundle.
Be fixed with columnar fixed cover in the end of supporting plate, locking bolt is arranged in the fixed cover coaxially, and the both ends of locking bolt reach respectively the outside of fixed cover, and locking bolt is with respect to the fixed cover axial restraint.
The inner end of fixed cover is riveted on the supporting plate, is provided with jump ring in the outside of fixed cover inner end on the locking bolt.
The utlity model has following effect: locking bolt can rotate under the drive of trundle in following the supporting plate motion process, and the set convex body in locking bolt outer end can be connected in the locking bolt hole on the doorframe, but the anti-theft effect of Effective Raise safe-guard door lock.Convex body on the locking bolt to realize with doorframe on the phase clamping of locking bolt hole, just the circumferential rotation by locking bolt realizes, do not need specially in lock body, to reserve the larger space for the locking bolt rotation, be conducive to the miniaturization of safe-guard door lock, and be convenient to the setting of other transmission mechanism in the lock body.By the rotation of the saturating groove realization locking bolt on trundle and the panel, simple in structure, the rotational stability of locking bolt is good.
Description of drawings

Fig. 2 is locking bolt and the supporting plate structural representation when being linked together, and fixed cover is vertically cut open.
Fig. 3 is the structural representation of trundle.
The specific embodiment
The bolt device of this door lock is arranged on the safe-guard door lock, and structure comprises supporting plate 9 and locking bolt 7, and the outer end of supporting plate 9 is provided with the flanging 10 perpendicular with main part, and locking bolt 7 can circumferentially be connected on the flanging 10 rotationally.The outer end of locking bolt 7 is provided with convex body 8, and convex body 8 protrudes into the outside of the outer peripheral face of locking bolt 7.The width of convex body 8 is less than the diameter of locking bolt 7, and convex body 8 is generally two, and they are located at the relative both sides of locking bolt 7 symmetrically.
Be fixed with columnar fixed cover 6 at described flanging 10, the mode of the inner end of fixed cover 6 by riveted joint realizes fixing with flanging 10.Be plugged in the fixed cover 6 to locking bolt 7 coaxial space, the both ends of locking bolt 7 all reach the outside of fixed cover 6, and convex body 8 is positioned at the outside of fixed cover 6 outer ends simultaneously.Arranged outside in fixed cover 6 the inners on locking bolt 7 has jump ring 13, by the restriction of jump ring 13 and convex body 8, so that locking bolt 7 is with respect to fixed cover 6 axial restraints.
Side face at the inner end of locking bolt 7 is provided with jack 11, is plugged with trundle 5 in the jack 11, and trundle 5 is positioned at the outside of jump ring 13.Be to improve the connectivity robustness of trundle 5 on locking bolt 7, be provided with pressure head 12 at the side face of locking bolt 7 inner ends, the top, the inner of pressure head 12 is pressed on the trundle 5.
Safe-guard door lock has panel 2, is provided with groove at panel 2, and trundle 5 is plugged in the groove with gap, and can thoroughly slide in the groove.Thoroughly groove is dihedral, and groove is to be made of the straight trough 3 that is connected as a single entity and skewed slot 4 thoroughly, and straight trough 3 is along the width setting of panel 2, and skewed slot 4 is in the setting that tilts of the length direction of panel 2.Have angle between straight trough 3 and the skewed slot 4, this angle is the obtuse angle, and when this was convenient to locking bolt 7 and follows supporting plate 9 motion, trundle 5 drove locking bolts 7 and circumferentially rotates.For further improving the smoothness of rotating when locking bolt 7 moves, trundle 5 is curved.
Supporting plate 9 is when moving towards lock body 1 lateral direction, trundle 5 is before this in straight trough 3 interior slips, because straight trough 3 is along the direction of motion setting of supporting plate 9, trundle 5 can not impel locking bolt 7 to rotate when straight trough 3 interior slip, and convex body 8 stably reaches the outside of the side panel of lock body 1.When treating that trundle 5 moves to the position, boundary of straight trough 3 and skewed slot 4, just peg graft in the locking bolt hole of convex body 8 on doorframe of this moment and put in place, under the restriction effect of skewed slot 4, trundle 5 impels locking bolt 7 circumferentially to rotate gradually, thereby finally finishes the clamping in convex body 8 and locking bolt hole.During the unlatching of safe-guard door lock, skewed slot 4 impels locking bolt 7 backward rotation by trundle 5 first, when treating that trundle 5 is positioned at the position, boundary of skewed slot 4 and straight trough 3, convex body 8 on the locking bolt 7 rotate in place, convex body 8 can stably be deviate from the self-locking keyhole, and finally is retracted in the hole set on lock body 1 side panel, that match with convex body 8 and locking bolt 7 outers.
