Abstract

The utility model relates to a lock head of a code-type latch anti-theft lock with a photoswitch, which comprises a lock sleeve, a lock core, latches, latch jacking rods, latch springs, a light-emitting element, a photosensitive receiving element and a key, wherein the lock core is fixed at the upper part of the lock sleeve; a key hole is formed on one side of the lock core; elongated slots and round holes corresponding to round holes on the lock core are formed at the lower part of the lock sleeve, the sizes of the round holes formed at the lower part of the lock sleeve are the same; 2 to 6 round holes are arranged into a row; a latch, a latch jacking rod and a latch spring which form a group are placed into each round hole; and holes for accommodating the light-emitting element and the photosensitive receiving element are correspondingly formed on two lateral surfaces at the lower part of the lock sleeve. When the key is inserted into the lock core 2, a curved surface with irregular key teeth transversely pushes the latches and the latch jacking rods to synchronously move towards the photoswitch consisting of the light-emitting element and the photosensitive receiving element, and further enables the latch jacking rods to perform reciprocating movement by compressing the latch springs; and the holes and the surfaces on the latch jacking rods can control the on/off of the electric current of the photosensitive receiving element, further enables the electric current to be acquired and decrypted by a circuit system, so that normal unlocking is realized. The head lock of the code-type latch anti-theft lock with a photoswitch has the advantages of simple structure, stable property and reasonable layout.

Description

Code type optoelectronic switch anti-theft cylinder lock tapered end

Technical field

The utility model relates to a kind of anti-theft cylinder lock, relates to particularly that a kind of machinery and electronics organically combine, simple in structure and safe and reliable code type optoelectronic switch anti-theft cylinder lock tapered end.

Background technology

As everyone knows, lock has long history.Anti-theft cylinder lock also has experienced one-hundred-year history, because its classics design, performance, inexpensive characteristics are liked by masses reliably! But its anti-pirate of the open performance is unsatisfactory, is easy to the technical pirate of the open of unlocking tool.Along with development of science and technology, modern lock is arranged core-locking type anti-theft cylinder lock, acoustic control lock, light-operated lock, fingerprint control lock or the like, kind, of all shapes and colors to develop into the combination of various multiple technologies from original mechanical antitheft lock as abnormal shape more.But be easy to also occur that key-cut inconvenience, password are easily stolen, problems such as information is unblanked in nonrecognition, method for unlocking complexity! Also bring a lot of worries when bringing the sense of security to masses.

Summary of the invention

The utility model provides for solving the technical problem that exists in the known technology that a kind of machinery and electronics organically combine, simple in structure and safe and reliable code type optoelectronic switch anti-theft cylinder lock tapered end.

The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: it comprises lock tube, lock core, pellet shot from a slingshot, marble spring and key, it is characterized in that: the top fixed lock core of lock tube, one side of lock core has circular hole, the bottom of lock tube have elongated slot and with lock core on the corresponding measure-alike circular hole of circular hole, one row has 2-6 circular holes, place one group of pellet shot from a slingshot, pellet shot from a slingshot push rod and marble spring in each circular hole, the two sides correspondence of lock tube bottom have a hole, place light-emitting component in one side opening, place photosensitive receiving element in another side opening.

The utility model can also be by the following technical solutions:

Described pellet shot from a slingshot push rod is made of cylinder identical with billiards diameter and the cuboid that has the hole, and they are integral.

Described light-emitting component 6 and photosensitive receiving element 7, their center line should be corresponding with the centerline hole opened on the pellet shot from a slingshot push rod 4 bottom cuboids.

The hole that has of the two sides correspondence of described lock tube 1 bottom is circular hole or square hole or slot.

Advantage and the good effect that the utlity model has are: machinery and electronics organically combine, simple in structure, dependable performance, rationally distributed, are convenient to the existing upgrading of producing cylinder lock producer to this kind series products.This design is locked the same use with common spring when not using anti-theft feature.

Fig. 2 is the A-A section structure schematic diagram of Fig. 1;

Fig. 3 is the B-B section structure schematic diagram of Fig. 1;

Fig. 4 is the structural representation of pellet shot from a slingshot push rod 4.

Among Fig. 1-Fig. 4: 1. lock tube, 2. lock core, 3. pellet shot from a slingshot, 4. pellet shot from a slingshot push rod, 5. marble spring, 6. light-emitting component, 7. photosensitive receiving element, 8. key.

The specific embodiment

For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows, see also Fig. 1-Fig. 4.

As Fig. 1-shown in Figure 3: the top fixed lock core 2 of lock tube 1, one side of lock core 2 has circular hole, the bottom of lock tube 1 have elongated slot and with lock core 2 on the corresponding measure-alike circular hole of circular hole, one row has 5 (general 2-6) circular holes, place one group of pellet shot from a slingshot 3 in each circular hole, pellet shot from a slingshot push rod 4 and marble spring 5, the two sides correspondence of lock tube 1 bottom have a circular hole (also can be square hole or slot), place light-emitting component 6 in one mother rib lateral rotundum, place photosensitive receiving element 7 in the opposite side circular hole, their center line should be corresponding with the centerline hole opened on the pellet shot from a slingshot push rod 4 bottom cuboids; As shown in Figure 4: described pellet shot from a slingshot push rod 4 is made of cylinder identical with pellet shot from a slingshot 3 diameters and the cuboid that has the hole and is integral.

Insert in the process of lock core 2 at key 8, the irregular curved surface of tooth on the key 8 laterally promotes pellet shot from a slingshot 3 and pellet shot from a slingshot push rod 4 moves to the optoelectronic switch direction that light-emitting component 6, photosensitive receiving element 7 are formed synchronously, compress marble spring 5 simultaneously, pellet shot from a slingshot push rod 4 is under the effect of pellet shot from a slingshot 3 and marble spring 5, can only move reciprocatingly with restriction owing to stomidium under the lock tube, the electric current that hole on the corresponding pellet shot from a slingshot push rod 4 and face can make photosensitive receiving element 7 forms through and off, and gathered and decipher, thereby normally unblank by Circuits System; Because of tapered end is made up of many groups pellet shot from a slingshot 3, pellet shot from a slingshot push rod 4, marble spring 5, light-emitting component 6 and photosensitive receiving element 7, key 8 teeth all can form the current signal of switching when passing through every group, will form one group of square matrix code that specific rule is arranged by the multidigit password, for Circuits System provides reliable password guarantee, thereby realize anti-theft feature.

Its advantage is: machinery and electronics organically combine, simple in structure, dependable performance, rationally distributed, are convenient to the existing upgrading of producing cylinder lock producer to this kind series products.This design is locked the same use with common spring when not using anti-theft feature.

Above-described embodiment is described preferred implementation of the present utility model; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that those of ordinary skills make the technical solution of the utility model all should fall in the definite protection domain of the utility model claims.
