Abstract

The utility model discloses an anti-theft lock with a rotating core, which is composed of a lock frame (1), a lock core (2) which can freely rotate in the lock frame (1) and can be pulled out and installed in according to requirements and a set bar (3). Compared with an existing lockset, the utility model can prevent thieves from using special tools to insert a keyhole to forcibly rotate and to destroy a rotor or a marble of the lock core for unlocking the lock, and the anti-theft lock has the advantages of firm structure, prying, cutting and impact preventing ability and convenient use, especially outstanding superiority in the aspect of theft protection for motorcycles.

Description

The core rotation type theftproof lock

The utility model relates to a kind of novel anti-burglar lock, especially a kind of core rotation type theftproof lock.

The lockset of people's use at present is various in style: pattern is different, but all be the traditional structure principle of continuing to use, promptly drive lock core rotor with key, stirring trip by rotor again finishes and unblanks and lock, that is to say that as long as lock core rotor is done with lock core and just relatively rotated and can unblank because lock core is fixed together with lock body, thief is easy to insert in the keyhole with special tool, twisting destroys lock core rotor or pellet shot from a slingshot by force, reaches the purpose of unblanking.Now, said method has become the customary means that thief unblanks to commit theft, and is particularly more common in the theft motorcycle.Conventional lock has also that pick-proof anti-is cut, the shortcoming of protecting against shock poor performance in addition.

The purpose of this utility model provides a kind of firm in structure, protecting against shock, pick-proof, anti-cutting, the particularly survivable novel lockset of lock core.

For achieving the above object, the utility model core rotation type theftproof lock is made up of lock frame and the lock core and the locking bolt that can freely rotate therein and can extract out as required and pack into, described lock core is the common lock core that can cross out two trips simultaneously, described locking bolt is that garden cylindricality end is connected with a movable wire cap, the movable wire cap has the notch of easy disassembly and can freely rotate around its staple, described lock frame is the U type, two ends have barrel-shaped lock core chamber, garden and locking bolt chamber respectively, the outdoor end internal diameter of lock core is outer through matching with lock core, the inner end internal diameter can be for the interior screw thread of movable wire cap folding dress with outer being associated with through matching of locking bolt, the indoor ring-like draw-in groove in garden that can hold the lock core trip just in addition of lock core, lock core can freely be rotated in the lock core chamber, the outdoor end sealing of described locking bolt, match in the position when its degree of depth is tightened with the movable wire cap.

As improvement of the present utility model, the lock core external surface is lower than outdoor mouthful of lock core slightly.

As further improvement of the utility model, this inner end, lock core chamber near locking bolt chamber one side, also has the level and smooth locking bolt chamber of certain-length except that screw thread.

Further improve as of the present utility model, the frame body of this lock frame is flat structure, and the lock frame also can be other shape beyond the U type.

After adopting above-mentioned design,, can prevent from that special tool from inserting in the keyhole to twist by force destruction lock core rotor or pellet shot from a slingshot and unblank because lock core can freely rotate in the lock core chamber; Because the lock core external surface is lower than lock core chamber mouth, more not easy-to-use other means fixed lock core slightly.Because after the movable wire cap of locking bolt was tightened, shut at the locking bolt two ends, make the shearing locking bolt lose extending space, thereby locking bolt have the anti-function of cutting; Locking bolt and silk cap adopt and flexibly connect, and the silk cap after can preventing to tighten unclamps by rotating lock bolt again; After tightening the movable wire cap simultaneously, also has the function that prevents to borrow locking bolt impact lock core.There is the level and smooth locking bolt chamber of certain-length inner end, lock core chamber again except that screw thread in addition, can increase the firm degree of lock and locking bolt; The frame body of lock frame adopts the flat structure, helps to improve anti-sled tensile strength under identical materials situation.The movable wire cap is twisted and is not twisted and can both lock, and the erosion control performance was better when ratio was not twisted when tightening, and the locking states that provides two kinds of different safe coefficients to need is easy for people to use.

Below in conjunction with accompanying drawing the utility model is described in further detail:

Fig. 1 is the three-dimensional structure diagram of the utility model core rotation type theftproof lock.

Fig. 2 is incomplete (lock core does not cut open) vertical view cutaway drawing of the utility model core rotation type theftproof lock.

As seen from Figure 1, Figure 2, the utility model core rotation type theftproof lock is made up of lock frame (1), lock core (2) and locking bolt (3).Lock core (2) and locking bolt (3) can freely rotate in lock frame (1), and can extract out as required and pack into.Lock core (2) is the common lock core that can cross out two trips (7) simultaneously.Locking bolt (3) is that garden cylindricality end is connected with a movable wire cap (6), and movable wire cap (6) has the notch (11) of easy disassembly, and its staple (9) of can having mercy on freely rotates.Lock frame (1) is that U type two ends have barrel-shaped lock core chamber (4), garden and locking bolt chamber (5) respectively, lock core chamber (4) the same lock core of outer end internal diameter (2) external diameter matches, the same locking bolt of inner end internal diameter (3) external diameter matches to be associated with and can supply the interior screw thread (10) of movable wire cap (6) dismounting, a ring-like draw-in groove in garden (8) that can hold lock core trip (7) is just arranged in the lock core chamber (4), lock core (2) can freely be rotated in the lock core chamber, and the position of draw-in groove (8) should make lock core (2) outer end concordant with lock core chamber (4) mouth.The sealing of outer end, locking bolt chamber (5), the degree of depth of locking bolt chamber (5) matches with the position of movable wire cap (6) locking bolt (3) when tightening.

As the novel improvement of this reality, lock core (2) external surface is lower than lock core chamber (4) collar extension slightly: inner end, lock core chamber (4) also has the level and smooth locking bolt chamber of certain-length near locking bolt chamber (5) one sides except that screw thread (10); The frame body of lock frame (1) is flat type structure, and lock frame (1) also can be other shape beyond the U type.

The utility model is not limited only to above-mentioned several embodiment, for the person of ordinary skill of the art, under the prerequisite that does not break away from the core rotation type principle, can also make some modification and improvement, and these also should be considered as belonging to protection domain of the present utility model.
