Description

Plum blossom lockset and matched key thereof

Technical field

The utility model relates to a kind of lockset, particularly a kind of plum blossom lockset and matched key thereof.

Background technology

The position of the keyhole in the plum blossom lockset of the prior art on the lock body is arranged on lock core hole upper end on the lock core with regard to the close neighbour, and stealer often can directly stretch into unlocking tool in the lock core hole, by dialling the methods such as pellet shot from a slingshot in lock core, reach the purpose of opening lockset easily, this shows that this class plum blossom lockset pick-proof ability is poor.Supporting with it key is made up of grip part and insertion section, and the insertion section directly is connected the grip part front end, and the insertion section is a hollow cylindrical, and its excircle is provided with the shrinkage pool that is complementary with lock core.

Summary of the invention

The purpose of this utility model is at not enough defective of the prior art, provides a kind of pick-proof performance good plum blossom lockset and matched key thereof.

For achieving the above object, the utility model adopts a kind of plum blossom lockset and matched key thereof, the plum blossom lockset comprises lock body, lock core, have one with the supporting key of plum blossom lockset and can insert the insertion section of lock core and the grip part that is connected with the insertion section tail end, be provided with connecting rod between the insertion section of key and the grip part vertically, the lateral dimension of connecting rod is less than the external diameter of insertion section, lock body front end at the plum blossom lockset forms die cavity, die cavity is suitable with the length of the connecting rod of key to the distance of lock core, the groove of one band opening is positioned at the upper surface of die cavity, the size of groove is less than the external diameter of the insertion section of key, offer on the outer wall of lock body with die cavity on groove key perpendicular and that be communicated with it put into the hole, it is suitable that key is put into the size of insertion section of the size in hole and key.

The groove that this practicality further is set on the lock body is a long through groove, and it is circular port that key is put into the hole, and the connecting rod cross section of key is circular.

The utility model is by providing a kind of plum blossom lockset and matched key thereof, be provided with connecting rod between the insertion section of key and the grip part vertically, the lateral dimension of connecting rod is less than the external diameter of insertion section, lock body front end at the plum blossom lockset forms die cavity, die cavity is suitable with the connecting rod size of key to the distance of lock core, the groove of one band opening is positioned at the upper surface of die cavity, the size of groove is less than the external diameter of the insertion section of key, offer on the outer wall of lock body with die cavity on groove key perpendicular and that be communicated with it put into the hole, it is suitable that key is put into the size of insertion section of the size in hole and key.When opening and closing lock, the hole is put into from the key of lock body in the insertion section of key stretch into, the connecting rod of key is put into the hole connecting portion along groove and key and is moved, and when key forwarded the position vertical with groove to, the insertion section of key faced lock core, just can realize opening and closing and lock.The size that antitheft principle of the present utility model is a groove is less than the external diameter of the insertion section of key, just mean that also the size of groove is less than the size of lock core hole certainly, even stealer uses unlocking tool to stretch into from groove, can not stir the circle pellet shot from a slingshot in the lock core simultaneously, can't reach the purpose of unblanking, if put into the hole and stretch into and attempt from the side key, more since key to put into orifice angle vertical with lock core hole, can't reach the purpose of unblanking, therefore the pick-proof performance of plum blossom lockset of the present utility model and matched key thereof is good.

The specific embodiment

As Fig. 1,2,3, shown in 4, this practical specific embodiment is a kind of plum blossom lockset and matched key thereof, the plum blossom lockset comprises lock body 1, lock core 2, have one with the supporting key 3 of plum blossom lockset and can insert the insertion section 31 of lock core 2 and the grip part 32 that is connected with insertion section 31 tail ends, be provided with the cross section between the insertion section 31 of key 3 and the grip part 32 vertically and be circular connecting rod 33, the diameter of connecting rod 33 is less than the external diameter of insertion section 31, lock body 1 front end at the plum blossom lockset forms die cavity 11, die cavity 11 is less than the distance of 31 bottoms to the insertion section, the top of the connecting rod 33 of key 3 to the distance of lock core 2, the microscler groove 12 of band opening is positioned at the upper surface of die cavity 11, the width of groove 12 is less than the external diameter of the insertion section 31 of key 3, but be greater than the diameter of the connecting rod 33 of key 3, offer on the outer wall of lock body 1 with die cavity 11 on the rounded key in groove 12 cross sections perpendicular and that be communicated with it put into hole 13, the internal diameter that key is put into hole 13 is greater than or equals to insert the external diameter of going into portion 31 of key.

The size that pick-proof principle of the present utility model is a groove 12 is less than the external diameter of the insertion section 31 of key 3, just mean that also the size of groove 12 is less than the size of lock core hole certainly, even stealer uses unlocking tool to stretch into from groove 12, can not stir the circle pellet shot from a slingshot in the lock core 2 simultaneously, can't reach the purpose of unblanking, if put into hole 13 and stretch into and attempt from the side key, more since key to put into hole 13 angles vertical with lock core hole, can't reach the purpose of unblanking.When we normally open and close lock, the hole is put into from the key of lock body in the insertion section of key stretch into, the connecting rod of key is put into the hole connecting portion along groove and key and is moved, when key forwards the position vertical with groove to, the insertion section of key faces lock core, just can realize opening and closing lock.
