Description

The vane type lock pin safe-guard door lock that has safeties

The utility model relates to the lockset that a kind of security door is used, and especially has the vane type lock pin safe-guard door lock of safeties.

At present, the employed vane type lock pin of security door safe-guard door lock is by lock body, blade, main dead bolt, oblique tongue, locking bar brace up and down, pusher dog, spring, reference column, cover plate, wainscot, outer panels, side's stalk, compositions such as handle.Adopt key and handle to carry out locking and unlatching, can realize multi-facetedly, Multi-point locking reaches the purpose of pick-proof.

But above-mentioned general vane type lock pin safe-guard door lock is anti-to be opened, and anti-function of spying on more can not be closed door lock without key indoor, and make its take precautions against performance and ease of use not good enough.

The purpose of this utility model provides a kind of safe-guard door lock with safeties, it can not only utilize key to finish multi-faceted and Multi-point locking, and available knob closes door lock, also keyhole can be sealed simultaneously, increased anti-unlatching, anti-function of spying on, thus precaution and ease of use improved.

The purpose of this utility model is achieved in that the device that is provided with three kinds of difference in functionalitys in lock body, promptly main dead bolt device, tiltedly tongue device and safeties.Preceding two kinds of devices can be finished the function of general safe-guard door lock, and then a kind of device has adopted sled mechanism.Slide plate one end riveting has the insurance keeper, when driving slide plate with knob and move, not only can but also can promote to insure keeper with the keyhole sealing, door lock is closed, thereby finish anti-the unlatching, anti-function of spying on locking.

Owing to adopted such scheme, can easily door lock have been closed indoor, and can prevent to open and spy on to indoor by keyhole from outdoor.Accomplish to realize the purpose of this utility model with novel and reliable structure.

With embodiment the utility model is further described with reference to the accompanying drawings.

Fig. 1 is a structural principle front view of the present utility model.

Fig. 2 is the sectional view of Fig. 1.

As shown in drawings, in lock body 3, be provided with the device of three kinds of difference in functionalitys, promptly main dead bolt device, tiltedly tongue device and safeties.

Main dead bolt device is by main dead bolt 2, reference column 11, blade 12, locking bar brace 17 compositions such as grade up and down.Three the cylindrical keepers of main dead bolt 2 and the lateral aperture of lock body 3 are slidingly matched, reference column 11 and lock body 3 riveted joints, and the fluting of the slotted hole of locking bar brace 17 and blade 12 is sleeved on the reference column 11 up and down.

Locking bar brace 17 and main dead bolt 2 interlocks up and down.When inserting with key in the keyhole 23, when stirring blade 12, make three cylindrical keepers of main dead bolt 2 and up and down locking bar brace 17 stretch out simultaneously, can finish the Multi-point locking of Three-bearing, reach the pick-proof purpose.During unlatching, key oppositely stirred just can.

Tiltedly the tongue device is by oblique tongue 1, torsion spring 4, spring abutment 5, pusher dog 6, wainscot 7, extension spring 8, side's stalk 9, compositions such as handle 13 and outer panels 18.Tiltedly the cylindrical bolt that bumps on the tongue 1 embeds in the lateral aperture of lock body 3, spring abutment 5 and lock body 3 riveted joints, torsion spring 4 is sleeved on the spring abutment 5, two shaft shoulders of pusher dog 6 place the locating hole of lock body 3 and cover plate 10 respectively, extension spring 8 can make pusher dog 6 and handle 13 reset, side's stalk 9 inserts in the square hole of pusher dog 6, and its end is connected with handle 13.Tiltedly tongue 1 is subjected to the elastic force effect of torsion spring 4 to keep stretching out state.Just locking voluntarily when door is closed conveniently plays the latch effect.Swing handle 13 just can be opened.

Safeties are by slide plate 14, lead 15, shift fork 16, torsion spring 19, spring abutment 20, compositions such as insurance keeper 21 and driver blade 22.

Long garden borehole jack is arranged on lead 15 on the slide plate 14 right-hand member planes, the left end riveted joint has insurance keeper 21, the limit groove at middle part has specific shape, it is equivalent to the part of tooth bar and the long pawl of shift fork 16 is meshed, lead 15 is riveted with the base plate of lock body 3, two shaft shoulders of shift fork 16 place the locating hole of lock body 3 and cover plate 10 respectively, the long pawl of shift fork 16 is equivalent to the part of gear and the special-shaped limit groove of slide plate 14 is meshed, and the groove of short pawl and the active section of torsion spring 19 reliably contact, and torsion spring 19 is loaded on the spring abutment 20.Spring abutment 20 and lock body 3 riveted joints, insert in the locating hole of lock body 3 sides the end of insurance keeper 21, and an end of driver blade 22 is inserted in the rectangular central aperture of shift fork 16, and the knob on the other end and the wainscot 7 is with hinge-coupled.

When during with knob turn left, through driver blade 22 shift fork 16 being rotated in the same way indoor, the long pawl of shift fork 16 stirs that slide plate 14 is parallel to be moved left, when moving to final position, is subjected to the elastic force effect of torsion spring 19 and locked.

Can illustrate from Fig. 1 dotted portion, the keyhole 23 on lock body 3 base plates can't be opened from outdoor slotting key by the sealing of the baseplane of slide plate 14 at this moment.Can not spy on to indoor from keyhole 23, realize anti-unlatching, anti-function of spying on, simultaneously, insurance keeper 21 also is pushed and puts in place, and door lock is closed, and has reached the purpose that just door lock can be closed at indoor not key.

When knob turn to the right, safeties return to opening again.

Can understand the attainable purpose of the utility model from above-mentioned.Can bring about tangible results after the enforcement.
