Description
Technical field
The utility model relates to a kind of safe-guard door lock that has sliding bolt.
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 a straight-bar type, and the pick-proof performance of this safe-guard door lock that has a straight-bar type is not good.For increasing the pick-proof performance of safe-guard door lock, a kind of safe-guard door lock that has arc-shaped lock bolt has also appearred now, the action of this arc-shaped lock bolt 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 and reaches the lock body outside, or is fully retracted in the lock body.Because the space of lock body inside is less relatively, and also need to be provided with other movable part in the lock body, this makes that the structure of toggle mechanism is comparatively complicated, and inconvenience is provided with described toggle mechanism in lock body, and the action stability of arc-shaped lock bolt is also bad.
The utility model content
For overcoming above-mentioned defective, the purpose of this utility model is: a kind of safe-guard door lock that has sliding bolt simple in structure is provided.
Reach the technical measures that described purpose is taked: a kind of safe-guard door lock that has sliding bolt, comprise lock body, be located at sliding bolt and supporting plate in the lock body, supporting plate is provided with distribution, on sliding bolt, be provided with inclined hole, has angle between the direction of motion of inclined hole and distribution, promoting is plugged in the inclined hole with gap, in lock body, be provided with lock bridge, lock bridge is to be made of connecting portion that is connected as a single entity and arc body, outer end at connecting portion is provided with gear in the home position place of arc body, in lock body, be fixed with pivot, be socketed on the pivot to gear clearance; Be provided with the tooth bar that is meshed with described gear on sliding bolt, under the drive of sliding bolt, described body is extended to the lock body outside, or is fully retracted in the lock body.
Described lock bridge is arranged in pairs in the lock body, and two lock bridges in the every pair of lock bridge are coaxial relatively to stack together, and corresponds respectively to a sliding bolt.
Be provided with slot on gear, the depth direction of slot is consistent with the short transverse of gear, and the outer end of described connecting portion is plugged in the slot.
Have the tooth that protrudes into the outside, connecting portion outer end on the described gear, these teeth extend in the thickness range of connecting portion.
In lock body, be provided with described lock bridge in the both sides of supporting plate.
This reality is novel to have following effect:
By the engagement between the rack and pinion, when sliding bolt moves, can drive the lock bridge body and reach the lock body outside, or be fully retracted in the lock body, simple in structure, the rotational stability of lock bridge in lock body is good.Rack and pinion can not take too much space in the lock body, has made things convenient for the design of safe-guard door lock, and convenient assembling to safe-guard door lock.Replace comparatively complicated toggle mechanism with rack and pinion, make the cost of safe-guard door lock low, safe-guard door lock is being locked or during open operation, it is laborsaving also to seem.

Fig. 2 is the structural representation of sliding bolt in this safe-guard door lock.
Fig. 3 is the front view of the cogged lock bridge of assembling in this safe-guard door lock.
Fig. 4 is the right view of the cogged lock bridge of assembling in this safe-guard door lock.
The specific embodiment
Originally the structure that has a safe-guard door lock of sliding bolt comprises lock body 1 and is located at supporting plate 11 in the lock body 1, and the end of supporting plate 11 is connected with the locking bolt 7 of straight-bar type, and under the shifting block on the tapered end drove, supporting plate 11 can drive locking bolt 7 and reach lock body 1 outside or be retracted in the lock body 1.
Vertically be fixed with on supporting plate 11 and promote 9, be provided with sliding bolt 2 in lock body 1, the outer end of sliding bolt 2 reaches the outside of lock body 1.Lock body 1 is box-like, and lock body 1 side plate is provided with stopper slot, and sliding bolt 2 is positioned at stopper slot with gap, when stopper slot slides at sliding bolt 2, is used to limit the position of sliding bolt 2.Sliding bolt 2 is provided with inclined hole 8, promotes 9 and is plugged on gap in the inclined hole 8, has angle between the direction of motion of inclined hole 8 and distribution 9.When supporting plate 11 motions were followed in distribution 9, distribution 9 can promote sliding bolt 2 and slide.
Be provided with lock bridge 12 in lock body 1, lock bridge 12 is to be made of connecting portion 6 that is connected as a single entity and arc body 5, is fixed with gear 4 in connecting portion 6 outer ends, and gear 4 is positioned at the home position place of arc body 5 simultaneously.Vertically be fixed with pivot 10 in lock body 1, gear 4 is socketed on the pivot 10 with gap.Be provided with the tooth bar 3 that is meshed with gear 4 at sliding bolt 2, when sliding bolt 2 moved, tooth bar 3 can drive lock bridges 12 by gear 4 and rotate, and makes body 5 reach lock body 1 outside, or is fully retracted in the lock body 1.
The lock bridge that is provided with is two covers in pairs, and this two covers lock bridge apportion is in the both sides of supporting plate 11, and each sliding bolt 2 is provided with two described tooth bars 3.
Taken up space by saving, on gear 4, be provided with slot, the depth direction of slot is consistent with the short transverse of gear 4, the outer end of described connecting portion 6 is plugged in the slot, thereby make have between the short transverse of the thickness direction of connecting portion 6 and gear 4 overlapping, thereby can effectively save two lock bridges that stack together 12 shared space in lock body 1.
Have the tooth that protrudes into the outside, connecting portion 6 outer ends on the gear 4, these teeth extend in the thickness range of connecting portion 6, thereby are convenient to the engagement between gear 4 and the tooth bar 3, the stability when improving tooth bar 3 transmissions.
When realizing the locking of this safe-guard door lock, body 5 reaches the outside of lock body 1, and two bodies 5 in a pair of lock bridge are fitted at lock body 1 Outboard Sections and stacked together, and fits and stack together in the outer end of two connecting portions 6.
