Description

A kind of lockable mechanism is located at the anti-stubborn anti-theft lock on lock core body

Technical field

The utility model is related to lockset manufacturing technology field, especially refer to a kind of lockable mechanism be located at it is anti-on lock core body Twist anti-theft lock.

Background technology

There are many illegal unlock method of prevalence in the world now:Hit spoon (English be Bump Lock) is unlocked, drill bit is unlocked, Pull lock core is unlocked, picklock is unlocked etc..And anti-illegal unlock technology is also with there are many kinds:It is prizing-proof lock core, anti-drilling Lock core is prevented pulling out lock core, anti-twistlock core (anti-snap), anti-bump key lock core (anti-bump) etc..

Currently, some robbers also begin to implement theft using the means that violence is unlocked, they are entangled with special socket bar Either the lock core head of outer side of door one is clamped with locking pliers and then firmly pulled up and down or left in the lock core head of outer side of door one The right side is firmly pulled, and is made the middle part fracture that lock core is weaker and is destroyed lock core structure, since the parts in lock core can be mutually detached from, The lock core of fracture can be extracted and then open lock by robber easily.

The middle part of lock core most weakness is twisted into two parts in order to prevent, and original lock core uses on a lock core body of outer side of door Vertical to open up anti-stubborn slot together, because than being more easy to disconnect in the middle part of lock core at one of outer side of door anti-stubborn slot, disconnection is lock One small section of part of core is to play the effect of protection lock core safety.Robber was twisted into two parts at the anti-stubborn slot of lock core in order to prevent later The methods of secondary violence unlocking is carried out with locking pliers again afterwards, prevent stubborn slot using setting twice, increase reinforcing member, but anti-theft effect It is not very satisfied to throw away.In addition, the lock core inner core that robber's rotation has been damaged in order to prevent is directly unlocked, therefore, spy must also be set Different mechanism is prevented, so, the structure of lock core is further improved.

Invention content

The purpose of the utility model is to make up above-mentioned deficiency, and simple and reasonable for structure, easy to make, energy is disclosed to society Enough it effectively prevent a kind of lockable mechanism that violence is unlocked to be located at the anti-stubborn anti-theft lock on lock core body.

What the technical solution of the utility model was realized in:

The utility model is described in further detail below in conjunction with the accompanying drawings:

Embodiment one, as shown in Figure 1 to Figure 3,

A kind of lockable mechanism is located at the anti-stubborn anti-theft lock on lock core body, including lock core inner core 1, lock core body 2, lock core inner core With the rows of marble hole of ordered series of numbers being arranged with being communicated in lock core body, the lower pellet 31 in lock core in in-core marble hole, lock core body Closure door pellet 32 at the top of marble hole, the spring 33 sealed up a door under pellet are upper in lock core body marble hole when lock core opening state Pellet 34 opens the thumb wheel 4 of lock tongue, be connected to driven on lock core inner core thumb wheel 4 in turn part 5, it is vertical on the lock core body 2 What is opened up prevents stubborn slot 21, and the inside that the anti-stubborn slot 21 is located on the lock core body 2 is provided with lockable mechanism, the lockable mechanism Include the closure door pin 61, locking spring 62 and lock pin 63 being set to from top to bottom in the pin hole of lock core body 2, it is described Consignment 64 is provided on lock core inner core 1, the lower section of the pin hole of lock core body 2 is stretched into the rear end of the consignment 64, in the lock core Be provided with the first locking hole 65 on core 1 below pin hole, it is described in turn to be provided with the second locking hole 66, lock core on part 5 Inside it is additionally provided with the mobile mechanism for making the second locking hole 66 be located at below the first locking hole 65 under the crack conditions of lock core front.

The mobile mechanism includes the rear top spring 71 being axially set in a lock core inner core 1 for inside and rear ejector pin 72, the front end of the rear ejector pin 72 offsets with the interior rear end for turning part 5.

Operation principle:

When installation, the side for being provided with anti-stubborn slot 21 is installed on outer side of door;When lock core is complete, the consignment on lock core inner core 1 64 rear end is located at the lower section of the pin hole of lock core body 2, and the lock pin 63 of lockable mechanism can not be fallen by 64 blocking of consignment.

When robber is unlocked with locking pliers come violence, they entangle the lock core head of outer side of door one with special socket bar The lock core head that outer side of door one is either clamped with locking pliers is then firmly pulled up and down or left and right is firmly pulled, and lock core can be anti- It twists and is twisted into two parts at slot 21, when robber, which will twist into two parts part, to extract outward, consign 64 as lock core inner core 1 is pulled out together;At this moment Lock pin 63 loses the blocking of consignment 64, hurtles down under the action of locking spring 62, simultaneously as after mobile mechanism The effect for pushing up spring 71, and under the position-limiting action of the stern notch because of the interior lug for turning part 5 in lock core inner core 1, inside turn the front end of part 5 with Lock core inner core 1 offsets, and interior the second locking hole 66 for turning part 5 is located at 65 lower section of the first locking hole.Lock pin 63 falls, its underpart The first locking hole 65 across lock core inner core 1 is fallen into interior the second locking hole 66 for turning part 5, to make lock core body 2, lock core inner core 1, the interior part 5 that turns forms an entirety, and then lock core is prevented to be opened.

Embodiment two, as shown in figure 4,

Lock core in the present embodiment is similar to the lock core structure in embodiment one, the difference is that in the present embodiment, it is described Mobile mechanism include preceding drawing pin 81 and the connecting pin 82 being axially set in the lock core inner core 1 of outer side of door, the preceding drawing Pin 81 is connected by connecting pin 82 with the lock core inner core 1 of outer side of door, the rear end of the preceding drawing pin 81 and the interior part 5 that turns Front end is connected.

When the front of lock core is twisted into two parts by violence, is extracted outward with part is twisted into two parts, inside turn part 5 in the lock core of extraction Core 1 is drawn forward under the action of preceding drawing pin 81 of mobile mechanism, to make the second locking hole 66 be located under the first locking hole 65 Side;Meanwhile 64 are consigned as lock core inner core 1 is drawn out, the whereabouts of lock pin 63 makes lock core body 2, lock core inner core 1, the interior part 5 that turns be formed One entirety, prevents lock core to be opened.

Embodiment three, as shown in figure 5,

On the basis of embodiment one or embodiment two, inclined-plane is added on lock core body 2, remaining structure is identical.

The lock core body 2 is being formed with the first inclined-plane 22 that outer side of door is high, low on the inside of door, institute positioned at the outside of anti-stubborn slot 21 The lock core body 2 stated is being formed with the second inclined-plane 23 that outer side of door is low, high on the inside of door positioned at the inside of anti-stubborn slot 21.

The rear end on first inclined-plane 22 and 21 flush of the anti-stubborn slot, the front end on second inclined-plane 23 and institute State 21 flush of anti-stubborn slot.

First inclined-plane 22 and the second inclined-plane 23 are set, so that locking pliers inconvenience is exerted a force, further enhances anti-theft performance.
