Description

The switchboard door lock

The utility model relates to a kind of low-voltage distribution or gauge tap cabinet door lock, particularly relates to a kind of switchboard door lock that has position-limit mechanism.

As everyone knows, traditional switchboard door lock adopts snap-lock, and its shortcoming is that the fastening function is relatively poor, still has the rolling momentum after locking, switchboard poor sealing, the feel of having no a sense of safety.CN2083177U, application number 91202051.2, the utility model title: low-voltage distribution the complete sets of equipment door lock mechanism, the door lock of this application have solved the problem of rocking after door lock is locked.But the door lock of this application does not have position-limit mechanism when unblanking, when causing key to twist not in place or stubborn lockset position of coupler, and the switchboard door phenomenon of still not opening, user's operation is not too convenient.

The purpose of this utility model is in order to make the switchboard door latch structure more rationally and the improvement technical scheme that proposes.

The utility model is achieved in that a kind of switchboard door lock, contain upper and lower lock body that is combined into, upper and lower central authorities of lock body have the circular hole that lock core is installed, in lock body, be provided with the groove cave that gear is installed, each chute of upper and lower both sides of lock body to there being one tooth bar is installed, lock core one end is the trough of belt hollow cylinder, the other end is punctured into the on-circular cross-section solid, solid passes and fixed gear, also contains locking bar, and feature of the present utility model is: gear band has position-limit mechanism.

Position-limit mechanism on the gear can be the long tooth of locating to be provided with than other tine length lengthening of gear at 0 ° and 180 °, tooth bar is approximate L shaped, two tooth bars are installed in the chute on lock body both sides with the antisymmetry form, square hole in the tooth bar cooperates with gear teeth, upper and lower locking bar is fastened on the transverse arm end of L shaped tooth bar respectively, laterally lock bolt sleeve is joined and is fixed on lock core on-circular cross-section solid end, rotates with lock core.

The lock core hollow circuit cylinder is sleeved in the locking closure central circular hole, the central circular hole of upper and lower combination lock body is a stepped hole, outside shrinking solid, lock core is with annulus, at upper and lower lock body circular hole upper and lower, respectively be provided with a step pilot hole, there is the projection fixing hole at the Dui Ying locking closure back side with it, and securing member passes upper and lower of lock body and is fixed tightly in the nipple hole of the locking closure back side.

The utlity model has good effect, set up position-limit mechanism in door lock, promptly locate to set up a pair of long tooth 0 ° and 180 ° of gear, it is spacing to realize unblanking and locking, and improves operating accuracy and reliability, has the sense of security.Easy and simple to handle, quick; Set up horizontal dead bolt in addition, further improve the locking stability of door lock; Locking closure is designed beautifully generous; The tooth bar antisymmetry is installed, and upper and lower locking bar becomes same vertical line, flexible movements, and it is safe to lock; Upper and lower of lock body adopts symmetric design, and the injection moulding manufacturing reduces mould, reduces cost.

Embodiment sees Fig. 1 to 11,1 is well-designed locking closure among the figure, elegant in appearance, there is vertical decorative pattern on the surface, there is a circular hole 13 centre, suit lock core 5, the fixing hole 14 that has two projections to form in center hole above and below, the back side of

locking closure

1,2,3,4 are respectively on the lock body, following part 9 and locking closure 1 be connected the securing member screw, packing ring, elastic washer, 5 is lock core, upper semisection is the trough of belt hollow cylinder, the on-circular cross-section solid 20 of lower semisection for shrinking, here adopt the square sectional solid, 6 for being sleeved on lock core on-circular cross-section contraction solid outside, be placed in the annulus cover in the part step circular hole under the lock body, 7 for being fixed tightly in horizontal dead bolt 11 trip bolt on the lock core 5 solid ends, 8 is gear, gear centre has a square hole 21 to pack in the solid 20 of lock core 5, gear is installed on the lock body, in the groove cave 15 of following part 9, locate respectively to be provided with a spacing long tooth 22 at 0 ° and 180 ° in the gear 8, when the rotation of lock core 5 driven gears, rotating to changes motionless after long tooth 22 is run into tooth bar 10, the groove of lock core hollow cylinder is at horizontal level at this moment, laterally dead bolt 11 also arrives horizontal level, locking bar inserts in the switchboard doorframe mating groove up and down, this moment, door lock was locked, 9 is on the lock body, following part, on, down lock body is a same structure, antisymmetry is installed and is combined into complete lock body, there is step circular hole 16 at the center, 15 for installing the groove caves of gear 8, and 18 for tightening up the connection stepped hole, on, there is tooth bar chute 17 on the down lock body both sides, 10 is L shaped tooth bar, in tooth bar 10 vertical arms, have the tooth bar square hole 19 mutually meshing with gear 8, have on the transverse arm of tooth bar tighten up vertical on, the mating holes of following locking bar 12 is fastenedly connected tooth bar 10 and locking bar 12 by securing member, the horizontal dead bolt 11 of step is fixed on the end of the solid 20 of lock core 5 by the square hole suit, with lock core 5 rotations.When lock core 5 rotates, driven gear 8 and laterally dead bolt 11 rotations, gear is stirred the tooth bar 10 and the locking bar 12 of two antisymmetry installations and is done upper and lower moving, finish latching operation, when lock core rotated round about, upper and lower locking bar shrank to the center, laterally dead bolt transfers to vertically, finish unlock operation, flexible and convenient operation, safe and reliable.
