In view of this, the utility model aims at providing a simple structure, it is convenient to dismantle and assemble to can guarantee the safe lock of security, in order to realize above-mentioned purpose, the utility model discloses a accomplish by following technical scheme: a safe lock comprises a lock body, a lock core and a lock tongue, and is characterized in that a lock core sleeve is fixedly arranged on the lock body, a lock sheet groove is arranged in the lock core sleeve, an opening is arranged at the upper end of the lock core sleeve, a rotary disc is arranged on the lock core, a lock sheet in the lock core is matched with a card, the card is matched with the lock sheet groove, the rotary disc synchronously rotates along with the lock core, a clamping groove is arranged on the rotary disc, the lock tongue is connected with a connecting rod, a buckle is arranged on the connecting rod, the buckle and the clamping groove are matched to work, a containing cavity for containing the buckle is arranged on the lock body, an elastic piece for enabling the connecting rod to abut against the rotary disc is arranged on the connecting rod, the rotary disc rotates to enable the buckle to fall into the clamping groove from the containing cavity through the opening, when the buckle falls into the clamping groove, the rotary disc, the reverse rotation of the rotary disc can extrude the buckle out of the clamping groove from the opening from the gap part to realize locking.

Still be equipped with on the lock body and prevent external damage locking device, it includes the pendulum rod to put external damage locking device, the pendulum rod articulates on the lock body, be equipped with the bayonet socket on the spring bolt, the front end of pendulum rod is equipped with the locking knot, the rear end of pendulum rod supports and leans on the casing, and the front end passes through the elastic component and makes the pendulum rod produce decurrent power all the time, the pendulum rod rear end breaks away from the restriction of casing, and the elastic component makes the locking knot fall into in the bayonet socket on the spring bolt.

The lock body is provided with a limiting bulge, and the depressed part of the step is matched with the limiting bulge on the lock body.

The utility model discloses mainly through set up a carousel on the lock body to through the connecting rod with spring bolt and carousel intercommunication, consequently, as long as rotate the lock core, just can rotate the carousel, thereby make the spring bolt realize shutting or the state of unblanking.

Drawings

The utility model discloses there is following figure:

FIG. 1 is a sectional view of the structure of the present invention;

FIG. 2 is a perspective view of the present invention;

fig. 3 is a perspective view of the connecting rod of the present invention leaving the slot.

Detailed Description

The drawings show the structure of the invention, and the details and the working principle of the embodiment are further described below with reference to the drawings: the safe lock comprises a lock body 1, a lock core 2 and a lock tongue 3, wherein a lock core sleeve 4 is fixedly arranged on the lock body, an opening 5 is arranged at the upper end of the lock core sleeve 4, a lock sheet groove is arranged in the lock core sleeve, an opening is arranged at the upper end of the lock core sleeve, a rotary disc is matched on the lock core, a lock sheet in the lock core is matched with a card, the card is matched with the lock sheet groove, when a key is inserted into the lock core, the lock sheet falls into the groove of the key, so that the card can be separated from the constraint of the lock sheet groove to realize rotation (not shown in the figure), thereby further realizing the unlocking function, a rotary disc 6 is matched on the lock core 2 and synchronously rotates along with the lock core, a clamping groove 7 is arranged on the rotary disc, the lock tongue 3 is connected with a connecting rod 8, a buckle 9 is arranged on the connecting rod 8, the buckle is matched with the clamping groove to work, the elastic member may be a spring or other elastic member. The carousel 6 rotates, makes buckle 9 falls into the draw-in groove the inside of carousel through opening 5 from holding the chamber, when the buckle falls into the draw-in groove, the carousel continues to rotate in the same direction and can drives the connecting rod pulling spring bolt and realize unblanking, the clearance between the external diameter of carousel and the internal diameter of lock core cover is less than the diameter of buckle, consequently, the buckle can not fall into this clearance the inside to, the opening part can produce a stop part, the carousel contrarotation can be followed the stop part that the clearance position produced and extruded the draw-in groove with the buckle from the opening part and realized shutting.

Still be equipped with on the lock body and prevent external damage locking device, prevent external damage locking device includes pendulum rod 12, the pendulum rod articulates on the lock body, be equipped with bayonet 13 on the spring bolt, the front end of pendulum rod is equipped with locking buckle 14, the rear end 17 of pendulum rod supports and leans on the casing, it explains here, because the casing is the components of a whole that can function independently including shell body and cap, is the disjunctor a bit, consequently, the casing here is the cap position, and the front end passes through the elastic component, and this elastic component also can be elasticity production parts (not shown in the figure) such as spring or extension spring or torsional spring and make the pendulum rod produce decurrent power all the time, the pendulum rod rear end breaks away from the restriction of casing, and the elastic component makes the locking buckle fall into in the bayonet. And when the cap position of casing was destroyed by external force, the pendulum rod had broken away from the constraint of cap, and its front end can be through the spring with the locking knot can fall into the bayonet socket of spring bolt in, realize the shutting, this just prevents under the prerequisite of external force destruction lock core, still can realize the shutting function.

The lock body is characterized in that a step 15 is arranged on the connecting rod, a limiting bulge 16 is arranged on the lock body, and a sunken part of the step is matched with the limiting bulge on the lock body. Therefore, the lock bolt can be prevented from being exposed excessively when the connecting rod is reversed by the lock cylinder, and the rotation angle of the lock cylinder is limited.
