Abstract
The utility model discloses a double interlock head, a group of interlock member is connected with two groups of single lock core, which is characterized in the integration of two single lock heads, and an double head interlock core is used for the lock. The machinery structure is characterized in that: an auto lock pin is arranged inside the interlock to integrate two lock cores into an auto locking member, which enables two lock cores to be interlocked. Two keys are required to open the lock, thereby effectively preventing the universal key from being opened.
Description
Affiliated technical field
The utility model relates to a kind of door lock assembly, can prevent that especially the master key sled from opening.
Background technology
At present the door lock that uses is to be combined by a tapered end, a lock core, and have one key operated.Very easily opened by the master key sled.
Summary of the invention
In order to overcome the deficiency of single head lock core door lock, the utility model door lock provides a kind of " dual-head conjoined tapered end ", and this lock not only has the function of pin tumbler lock, and has the double end twin-core insurance function that contracts mutually, prevents that effectively the master key sled from opening.
This " dual-head conjoined tapered end " has fundamental difference in design with traditional one group of single head lock core door lock, the technical scheme that its technical solution problem is adopted is: it is to adopt two groups of tapered ends and lock core combination, one group of conjuncted mechanism of middle design, two groups of lock cores are formed by connecting, three groups of special lock pin pellets shot from a slingshot are arranged in this is conjuncted, connecting two groups of lock cores is one, forms interlock
The beneficial effects of the utility model are: not only have the function of bullet tapered end, have the interlocking insurance function simultaneously, adopt two keys of primary and secondary during use, and easy to operate.
Description of drawings
Below in conjunction with accompanying drawing the utility model is illustrated:
Fig. 1 is the plan view of this dual-head conjoined tapered end.
Fig. 2 is the A-A sectional view.
Among the figure: 1. lock body (inferior), 2. lock core (inferior), 3. conjuncted, 4. dead bolt, 5. lock core (master), 6. lock body (master), 7. key (master), 8. key (inferior), 9. conjuncted self-lock pin (three groups).
The specific embodiment
(1) inferior lock body, (3) conjuncted, (6) main lock body are linked as assembly among the figure, by (3) conjuncted in, (9) conjuncted three groups are combined into self-locking device to, (5) main lock core with (2) inferior lock core from trivial pin, realize interlocking (no key insertion state).
(1) locks a door.
1. will arrive the precalculated position in (8) inferior key insertion (2) inferior lock core, make three groups (9) conjuncted self-lock pin action, open conjuncted letter lock device, remove the interlock function of (5) main lock core and (2) inferior lock core.
2. (7) master key is inserted (5) main lock core, rotate 360 ° of (5) lock cores and rotate 360 ' synchronously with (4) dead bolt, door lock is sealed.
3. extract (7) master key, (8) inferior key successively, (9) conjuncted self-lock pin automatically resets, conjuncted self-locking device action.(5) main lock core is carried out interlocking with (2) inferior lock core, and locking a door finishes.
(2) unblank.
1. with locking a door (1), omit.
2. (8) inferior key is motionless, rotates (7) master key, makes (5) main lock core and the action of (4) dead bolt, and door lock is opened.
3. extract (7) master key and (8) inferior key successively, (9) conjuncted self-lock pin automatically resets, conjuncted self-locking device action, and (5) main lock core is realized interlocking with (2) inferior lock core, unblanks to finish.
Claims (3)
1. one kind " dual-head conjoined tapered end " is combined into one by one group of conjuncted mechanism in the middle of two groups of single head door locks, it is characterized in that: three groups of self-lock pins of design in conjuncted, connect the double end lock core by self-lock pin respectively, and the double end lock core is combined into self-locking device.
2. require described " dual-head conjoined tapered end " according to right 1, it is characterized in that: be divided into the primary and secondary lock core and connect two groups of lock cores by the in-house three groups of lock pin pellets shot from a slingshot of disjunctor and combine interlock.
3. require described " dual-head conjoined tapered end " according to right 1, it is characterized in that: this tapered end comprises two keys of primary and secondary, inferior key open and close interlock, and master key is realized the open and close door lock.
