Description
Of the present utility model pair of bolt safety lock belongs to a kind of lockset.
Prior art has the double door bolt formula safety lock (China Patent No. 98251075.6) of double door bolt-lock (China Patent No. 91205335.6) and my design in 1998 at present, and it is convenient inadequately to there is operation, the not ideal enough deficiency that waits of security performance.
The purpose of this utility model is, at the deficiencies in the prior art, proposes a kind of double door that can be used for, and also can be used for two safety locks of fastening of single open-door.
Fasten safety lock for of the present utility model pair, by housing (1), lockhole housing (2), lock is fastened (3), big lock is fastened (4), driven wheel (5), lock pin drive rod (6), lock pin (7), spring (8), lock is fastened slip positioning strip (9), core (11), (12), knob handle (15), handle (16) is formed, it is characterized in that: its lock is by driven wheel (5), and big lock is fastened (4), and little lock is fastened (3), lock pin drive rod (6), lock pin (7), spring (8) the match locking that constitutes or the drive unit of unlatching.Of the present utility model pair of bolt safety lock, little locking bolt (3) is provided with core rotating moving piece contact turn position cavity (23), is provided with one by outer lock core revolving fragment contact driving sliding bevel (c), and its chamfered angle a should be advisable 40 ° of-70 ° of scopes.Be provided with locking bolt tongue (25) at little locking bolt (3), in (25), be provided with location hole of the spring groove (19), so that the installation of spring.In little locking bolt (3), also be provided with and lock turn-knob field joint (22), be provided with in the joint and lock turn-knob bolt hole (20), with lock bolt location anticreep pin-and-hole or screw (21), make and lock turn-knob and rotate within the specific limits and realize tightening or unclamping, be unlikely to produce obscission again.Lock pin drive rod of the present utility model (6) is provided with inner lock core contact-actuating (f), outer lock core contact-actuating (e), and lock pin drives the contact (n) of unblanking, turn axis hole (26).Of the present utility model pair of bolt safety lock, big locking bolt is provided with location hole of the spring, groove (19), outside playing the location, the more important thing is and can adopt long spring, makes it to have stronger stretching strength.The tooth bar (29) that is complementary with gear (5), but profile of tooth, replace profile of tooth better with boring, performance can satisfy instructions for use and be easy to processing, time and labour saving.When the utility model is locked down, when door is pulled on, little locking bolt (3) is finished one automatically and is contracted and stretch action under the effect of spring, and little dead bolt (25) inserts lockhole (2) automatically and is in locking states, at this moment, turn handle turn-knob (15) makes big locking bolt (4) move to the A direction from B, when entering lockhole (2) precalculated position, lock pin (7) is under automatic locking under the effect of spring, and this moment, big or small locking bolt was in the state of closing.When unblanking with key outdoors, core (11) running contact at first acts on the expense of little locking bolt and tiltedly touches face (c), little locking bolt is moved to the B direction from A, make little dead bolt (25) leave pin-and-hole (2) and when opening, (e) that the running contact of core (11) arrives drive rod (6) touches face, continue turn, (e) move to the H direction, the unlatching sheet (m) of the lock pin of the lock pin all-or-nothing piece (n) of drive rod (6) driving meanwhile moves to the K direction, move to the K direction thereby drive lock pin (7), when arriving the precalculated position, lock pin (7) is in the full open state, at this moment, big locking bolt (4) moves to the B direction from A under the effect of spring, withdraws from lockhole (2), at this moment, big or small locking bolt is all opened.Door is opened.When the door drawback lock, with key turn core (12), (f) that the core contact drives lock pin drive rod (6) touches face, make it when the H direction moves, the unlatching sheet (m) that lock pin all-or-nothing piece contact (n) drives lock pin moves to the K direction, and when lock pin (7) arrived the full open state, big locking bolt (4) moved to the B direction from A in the effect of spring, leave lockhole (2), big locking bolt full open.Pulling is locked turn-knob (13) and is made it to move to the B direction from A in door, arrives dead-centre position, and dead bolt (25) all withdraws from lockhole (2), and this moment, big or small locking bolt was all opened.In door, lock turn-knob (13), when tightening, can make little locking bolt be fixed in locking or opening.(13) unclamp after, little locking bolt is in automatically down lock state.Of the present utility model pair of bolt safety lock, its little locking bolt (3) is under the locking states, and turn-knob (13) is tightened in turn, promptly play the effect of locking, at this moment, with the key driving little locking bolt (3) is moved outdoors, promptly can not open little locking bolt (3), more can't open big locking bolt (4).In door, there is not key, can not open door, lock turn-knob (13) with the hand-screw pine, (12) are moved to the B direction, can drive little locking bolt and open, during manually opened little locking bolt, little locking bolt is not opened the function of big locking bolt, have only in door with key and could open big locking bolt, this also is one of insurance function of this lock.Because the special entity of the two above-mentioned designs of bolt safety lock of the utility model, and obtain especially, stronger insurance function.More convenient for lockset is installed, positioning performance is better, can be provided with interior envelope locating piece (10) is installed, and also can not establish.Spring is dispensable structure because of following closely position breach (31) and lock pin position mouth (33), can decide with needs as the case may be.
Advantages such as of the present utility model pair of bolt safety lock has compact conformation, makes, easy to assembly, and the insurance design is special, and the security insurance performance is good.
