The specific embodiment

Describe the specific embodiment of the invention in detail below in conjunction with accompanying drawing.

Fig. 1, Fig. 2 and shown in Figure 3, a kind of safety lock comprises lock object 1, lock housing body 2, lock core 3 and key 4; The lock housing body is provided with connector 201, and lock object inserts in the connector, inserts the connector middle part at lock object and is arranged with lock slots or lock plane 101, and key is operated lock slots or the lock plane that the lock core that is complementary could contact or leave lock object.

Lock housing body internal cylinder is other to be provided with the locking device that an instrument that prevents to use non-key prizes lock core, and locking device is made of spring 6 and pellet shot from a slingshot 5, but locking device also the mounting spring sheet replace pellet shot from a slingshot and spring.Also can small magnet be installed at the pellet shot from a slingshot head, spring replaces with magnet, and the principle of utilizing the same sex to repel each other plays spring action.Also can only use pellet shot from a slingshot, replace spring by gravity without spring.Pellet shot from a slingshot withstands under the active force of spring in the breach 301 of lock core head setting usually; When in key inserts the lock housing body, being complementary with lock core, behind pushing spring leaf or the pellet shot from a slingshot, could rotary locking cylinder.Make lock core contact or leave and the lock slots of deadlock lever or contacting of lock plane, so that locking or open protected electric fixtures.

Connector 201 is an open type on the lock housing body, and connector is made of with lock housing body middle part two parts the gland 204 that screw 203 is fixed together.

Fig. 1, Fig. 2 and shown in Figure 3 are the safety locks of band plane gland.Connector 201 mid-planes are separated on the lock housing body, and gland 204 is fixed on the lock housing body by two screws 203, can be provided with between gland and the lock housing body to adjust pad 205.

Fig. 4 and shown in Figure 5 is the safety lock of " U " font gland of band.Gland is for falling " U " font structure, and gland 204 is fixed on the square platform of lock housing body protrusion by the side of screw 203 from gland on the square platform 206 that tips upside down on lock housing body protrusion.

Fig. 6 and shown in Figure 7, a kind of safety lock with fluting.Offer the open slot 202 that a kayser is used perpendicular to connector 201 on the lock housing body, the screw 203 of an anti-avulsion is equipped with at the notch place.

After above-described screw 203 was tightened gland 204, screw 203 holes on the gland were by lead sealing.
