The utility model overcomes the single technical defect that also can open two keys locks who exists among the prior art provides two people of needs and has cooperated and to realize the operation of unblanking and lock.
Description
Technical field
The utility model relates to a kind of building materials Hardware fitting, specifically conbined public or double key lockable mechanism.
Background technology
Our lockset used in daily life, great majority are all the corresponding locksets of a key.But under some particular surroundings, then propose special requirement.Such as in the designing requirement of firearms and ammunition safety cabinet, need two people to open when emergency machine is locked in unlatching simultaneously, just can open cabinet door.This just needs a kind of lockable mechanism of particular/special requirement, needs the lock core arranged for two key turns, and by lock core and link gear thereof drive dead bolt away from or be inserted in locked groove, thus realize the lock of door body or open.
Provide a kind of conbined public or double key lockable mechanism in prior art, comprise a lock core, this lock core provides two lockholes penetrated for key, drive the plectrum on lock core to rotate by the synergic rotation of two keys, described plectrum drives dead bolt to move relative to locked groove.
There is following technological deficiency in above-mentioned technology: owing to being penetrated for two keys by a lock core simultaneously, so just can inserting two keys by a people simultaneously and unlock, so just not reach the object that two people unblank mutually to supervise.
Utility model content
The utility model is intended to provide a kind of needs two people to coordinate the conbined public or double key lockable mechanism that could realize unlock operation.
Conbined public or double key lockable mechanism in this programme, comprise a dead bolt, two lock cores and two plectrums be located at respectively on lock core, rotating shaft is equipped with between each plectrum and dead bolt, one end of described rotating shaft is rotatably connected on dead bolt, self-locking mechanism is provided with between the other end of described rotating shaft and plectrum, described self-locking mechanism comprises the axle sleeve being sleeved on rotating shaft outside, this axle sleeve is fixed on dead bolt, described axle sleeve is provided with guide, be provided with alignment pin in guide, described rotating shaft is provided with locating slot, and described alignment pin is penetrated in locating slot by guide.
Adopt the technical solution of the utility model, there is following technique effect:
If alignment pin penetrates in locating slot by 1, so described dead bolt, rotating shaft and plectrum will be fixed together in turn; If only have a dead bolt, even if dead bolt, rotating shaft and plectrum are fixed in turn, plectrum also can drive dead bolt to swing; But have two plectrums and be fixed together by respective rotating shaft and dead bolt, the position of action point of two plectrums is different, if simultaneously to two plectrum forces (inserting key, rotational lock core), the force effect of two plectrums can pin down each other, makes which plectrum that dead bolt all cannot be driven to move.
If alignment pin shifts out by 2 in locating slot, two rotating shafts just can be rotated relative to described plectrum, and the restraining function between such two plectrums just can disappear, and two plectrums, when rotating in same direction, can drive described dead bolt to move relative to locked groove.
3, in sum, the operation of locking or opening be carried out, two alignment pins and key must be operated simultaneously, so just considerably increase the difficulty of one man operation, need two people to coordinate and could realize unblanking and upper latching operation.
Further, back-moving spring is provided with between described alignment pin and guide.
Alignment pin can be penetrated in locating slot automatically by back-moving spring, realize automatic locking.
Further, its one end passing guide of described alignment pin is provided with draw ring.
Described draw ring, provides the handle that convenient operation personnel pull alignment pin.
Further, the length direction of described guide and the radial direction of axle sleeve consistent.
If adopt the length direction of guide consistent with the axial direction of axle sleeve, can make to produce certain interference between alignment pin and rotating shaft.By consistent with the radial direction of axle sleeve for the setting of the length direction of guide, belong to a kind of optimal design.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model conbined public or double key lockable mechanism embodiment.
Fig. 2 is self-locking mechanism structure enlarged diagram in Fig. 1.
Detailed description of the invention
Below by detailed description of the invention, the utility model is described in further detail:
Reference numeral in Figure of description comprises: door-plate 23, lock core 22, plectrum 24, rotating shaft 2, dead bolt 21, axle sleeve 1, alignment pin 3, guide 6, draw ring 5, back-moving spring 4, locating slot 7.
As shown in Figure 1, the present embodiment conbined public or double key lockable mechanism, comprises a dead bolt 21, two lock cores 22, is located at two plectrums 24 on lock core 22 and is located between each plectrum 24 and dead bolt 21 and is equipped with rotating shaft 2 respectively.
As shown in Figure 1, described lock core 22 and plectrum 24 are in the side of door-plate 23, and described dead bolt 21 is in the opposite side of door-plate 23, and described rotating shaft 2 is through described door-plate 23, one end of described rotating shaft 2 is rotatably connected on dead bolt 21, is provided with self-locking mechanism between the other end of described rotating shaft 2 and plectrum 24.
As shown in Figure 2, described self-locking mechanism comprises the axle sleeve 1 being sleeved on rotating shaft 2 outside, and this axle sleeve 1 is fixed on dead bolt 21, described axle sleeve 1 is provided with guide 6, be provided with alignment pin 3 in guide 6, described rotating shaft 2 is provided with locating slot 7, and described alignment pin 3 is penetrated in locating slot 7 by guide 6.
