Abstract

The utility model relates to a rainproof, dustproof and burglarproof lock cylinder and a key, which are mainly characterized in that the shell and the inner cylinder of the lock cylinder are correspondingly provided with a stop key way, a stop key provided with an inclined plane is arranged in the stop key way, a part on the circumferential wall of the shell and corresponding to the stop key is provided with an elastic pushing component of an outer stop key, an elastic sheet hole communicated with a key hole is formed on the circumferential wall of the inner cylinder, a specially-shaped elastic sheet and an elastic sheet pressure spring are arranged in the key hole, a key socket door-closing component is arranged at the unlocking end of the lock cylinder, and four rows of teeth are formed on the two sides of the key matched with the lock cylinder. With the structure of the specially-shaped elastic sheet, the lock cylinder can greatly reduce the probability of technical unlocking and violent unlocking, and can effectively prevent burglary unlocking by all kinds of technical tools; besides, the transformation amount of tooth shapes of the key is between 60,000 and 1,600,000 so that the mutual unlocking rate of keys is extremely low, so that the key cylinder has the advantages of safe use, simple manufacture, low manufacture cost and the like, and can be matched with all kinds of door locks and frame locks.

Description

Rain-proof dust-proof anti-theft lock and key

Technical field

The utility model belongs to lock technology field, is specially adapted to supporting rain-proof dust-proof anti-theft lock and the keys of general lock body such as door lock and lock.

Background technology

Lockset commonly used mostly is a cylinder lock, and the pellet shot from a slingshot hole of cylinder of spring lock mostly is radially setting, and not only key is prepared easily, even dials the twist lock inner core with a slice substance, can unblank, and theftproof performance is poor.At present, disclosed various locks on the market in the improvement that all has aspect pellet shot from a slingshot arrangement and the Key structure in various degree, have plenty of at the teeth and the gathering sill position of key and take some structural measures, but still have the mutual opening rate height and copy easier defective.Also has plenty of the multiform shape of key body being made three tooth punchings, though anti-theft effect improves to some extent complex manufacturing technology.Along with the development of social science and technology, the high iq crime constantly increases, and the theft technology is also more ingenious, and therefore, it is very necessary to research and develop novel anti-theft lock.In addition, existing cylinder of spring lock, its key hole mostly is smooth open type, and not dustproof, rainproof measure cause the corrosion or the obstruction of lock core easily.

The utility model content

The purpose of this utility model provides and a kind ofly can more effectively prevent technology and violence pirate of the open, improves the lockset theftproof performance, and mutual opening rate is low, and can effectively avoid rain-proof dust-proof anti-theft lock and the key thereof copied.

Realize that the technical scheme that the purpose of this utility model is taked is: correspondence is provided with blocking key groove on the overcoat of this lock core and the inner core, the block key on band inclined-plane is housed in the blocking key groove, block key elasticity holds out against assembly outside being provided with the block key corresponding position on the circumferential wall of overcoat, the circumferential wall of inner core is provided with the shell fragment hole that is communicated with keyhole, be laid with special-shaped shell fragment and shell fragment stage clip in the hole, the lock core opening end is provided with the key hole assembly of sealing up a door, with the supporting two-sided four toothrow teeth that have of key of lock core.

The described key hole assembly of sealing up a door has a lid of sealing up a door that is installed in that lock core unblanks to hold and rolls position, both sides that key, two rolls key and be fixed on the return spring that covers on the inside wall of sealing up a door and be connected with a pair of sealing up a door of being in contact with one another.

The described closed contact surface that rolls key of sealing up a door is an arc.

Described elasticity holds out against assembly and is made of block key pellet shot from a slingshot, holddown spring and shutoff.

Shell fragment hole on the described inner core is that 8～12 double symmetries are laid.

Rain-proof dust-proof anti-theft lock and the key made according to such scheme, adopt special-shaped elastic piece structure, can reduce the probability that technical opening and violence are opened greatly, and can prevent the pirate of the open of various technical tools effectively, the conversion quantity of its shaped as key bit is 60,000～1,600,000, make the key mutual opening rate extremely low, this lock core has advantages such as safe in utilization, simple for production, that cost is low, can with the supporting use of the lock body of various door locks and lock.

The specific embodiment

Referring to Fig. 1, Fig. 2, Fig. 3, rain-proof dust-proof anti-theft lock of the present utility model and key comprise inner core 1, overcoat 2, block key 3, block key pellet shot from a slingshot 4, holddown spring 5, shutoff 6, shell fragment hole 7, shell fragment stage clip 8, special-shaped shell fragment 9, return spring 10, seal up a door cover 11, roll key 12, locating slot 13, shop bolt 14, interior blocking key groove 15, outer blocking key groove 16, key hole 17, key 18, each member is formed whole lock core.Wherein, interior blocking key groove 15, outer blocking key groove 16 are two pairs, and symmetry is located on the circumferential wall of inner core 1 and overcoat 2 respectively.Two block keys 3 place respectively in the inside and outside blocking key groove 15,16.On the circumferential wall of overcoat 2 with outside blocking key groove 16 corresponding positions be provided with block key elasticity and hold out against assembly, this assembly is made of block key pellet shot from a slingshot 4, holddown spring 5 and shutoff 6, block key pellet shot from a slingshot 4 touches mutually with block key 3, and block key 3 is pushed to the center of inner core 1 under the pressure effect of holddown spring 5.The shell fragment hole 7 of inner core 1 is 8～12 double layings, corresponding with two block key 3 positions respectively, abnormity shell fragment 9 (referring to Fig. 4) is connected in the shell fragment hole 7 by return spring 10, can move up and down along shell fragment hole 7, because what special-shaped shell fragment 9 adopted is special-shaped gabarit, can reduce the probability that technical opening and violence are opened greatly.Referring to Fig. 5, Fig. 6, key hole 17 is located at the centre of inner core 1, supporting with it key 18 is for directly tabular, the two-sided four toothrow teeth that have, after it inserted keyhole, its teeth promoted special-shaped shell fragment 9 block key 3 are pushed in the outer blocking key groove 16, break away from interior blocking key groove 15, be rotatable inner core 1, realize the unlatching of lock body, significantly reduce the mutual opening rate of key thus.The lock core opening end is provided with the key hole assembly of sealing up a door, this assembly have one by locating slot 13 and shop bolt 14 sealing up a door of being installed in that lock core unblanks to hold cover 11 and a pair of sealing up a door roll key 12, two positions, both sides of rolling key be fixed on the return spring 10 that covers on 11 inside walls of sealing up a door and be connected, after key 18 is extracted, two roll key 12 is in contact with one another closure under the pressure of return spring 10, can prevent that dust, rainwater from entering in the key hole 17, the two closed contact surfaces that roll key 12 are arc, are convenient to the reeve of key 18 and extract.
