Abstract
The utility model provides a magnetic lock protection device for anti-theft door and comprises a lock protection casing, a key hole at the lock casing and a magnetic lock protection. The utility model is characterized in that the lock protection casing is provided with an arm board driven by a lock core of the magnetic lock protection with a pin shaft and a lock protection start device formed by a moving connecting rod which is respectively connected with the pin shaft and a lock protection baffle. When opening the door, users can open the lock protection device and an anti-theft door lock with a key, which has convenient operation without remembering any code. Besides, the lock core of the lock protection device is provided with a smooth key channel, thereby avoiding blocking the key channel due to eyewinker or glue water and effectively preventing a magnetic marble from being damaged and improving the service life of the lock protection device. Therefore, the utility model is a relatively ideal lock protection device for anti-theft door.
Description
The utility model relates to a kind of door lock protective device, especially a kind of Lock protector that the security door door lock is protected.
The security door lock-protector of known technology production mostly is the mechanical code device, complex structure not only, and the manufacturing cost height, and also the unlatching of lock-protector is comparatively complicated, and to remember the password of accurate lock, otherwise will be difficult to open the door.The repetition rate of coding of this class encryption apparatus is higher in addition, is easy to be decrypted, and can not play real antitheft effect.That Chinese patent 98203007X discloses is a kind of " full-automatic lock-protector ", and it utilizes the magnetic pole permutations of known magnetic pin, is combined into very many cipher symbols, need not memory cipher, and password is stored in key and the lock-protector naturally.But still there is complex structure in it, is difficult to deficiencies such as manufacturing, therefore, is necessary prior art is improved.
The purpose of this utility model is to overcome the deficiency of prior art, provide a kind of simple in structure, need not memory cipher, lockhole can not block up, hold with same key the security door magnetic lock-protector of two locks.
The utility model is realized by following technical proposal: it comprises protects lock housing, be located at the keyhole and the magnetic of protecting on the lock housing and protect lock, it is characterized in that protecting lock housing be provided with the lock core that protects lock by magnetic drive the arm plate which is provided with pivot pin of its rotation and respectively with pivot pin with protect the lock-protector opening device that movable rod constituted that the stopper plate links to each other.Described arm plate is the lobe plate of a middle part perforate, and the perforate at middle part places on the lock core of magnetic lock by jump ring, so that the arm plate can be rotated with the rotation of lock core.Described pivot pin one end is fixed on the cam point of arm plate, and the other end is fixed on the connecting rod.Described movable rod is made of two straight-bars that vertically link into an integrated entity, and wherein one end links to each other with shaft lock, the end of another root with protect the stopper plate and link to each other, the rotating band moving axis pin by the arm plate rotates, connecting rod is upper and lower to be moved thereby make.The described stopper plate that protects places and protects the lock housing inboard, has through hole on it, when protecting the stopper plate under connecting rod promotes and when mobile, the through hole on it with protect lock housing on keyhole and the lockhole on the security door be communicated with, can open safe-guard door lock.
The utility model compared with prior art has following advantage and effect: since protect be provided with on the lock housing simple in structure; dependable performance; lock-protector opening device easy for installation; and make the Magnetic lockwork that protects on the lock housing consistent with the Magnetic lockwork on the security door; make the user when opening the door; only need to open lock-protector and safe-guard door lock simultaneously with same key; not only easy and simple to handle; and need not remember any password; in addition because the Magnetic lockwork on the lock-protector is provided with a passage; and magnetic bullet is hidden in the passage inboard fully; make passage form a smooth key channel; neither can stop up this key channel because of the existence of foreign matter or glue; effectively protect magnetic bullet not impaired again; is improved the application life of lock-protector, therefore, is a kind of comparatively desirable security door lock-protector.
Fig. 1 is the perspective view of the utility model;
Fig. 1 is the structure schematic diagram of the utility model.
Below in conjunction with accompanying drawing the utility model is described further, is not limited in this but hold within the utility model.
Among the figure, 1 for protecting lock housing, be installed on the security door, 2 protect lock for magnetic, its lock core shell 21 and lock core inner bag 23 are provided with magnetic bullet 22 and mechanical positioning pellet shot from a slingshot 25, on lock core inner bag 23, be provided with a smooth key channel 24,3 is key, which is provided with mechanical billiard 31 and magnetic bead 32, in the time of in it inserts passage 24, can drive lock core inner bag 23 rotates, finish magnetic and protect the unlatching of lock 2,4 is the opening device of lock-protector, arm plate 42 on it is the lobe plate that a middle part has hole 47, hole 47 is installed on the lock core inner bag 23 of magnetic lock by jump ring 48, so that rotate with the lock core inner bag, the cam point of arm plate 42 is provided with pivot pin 41, the other end of pivot pin 41 is fixed on the connecting rod 43, connecting rod 43 and connecting rod 44 vertical linking into an integrated entity, the other end of connecting rod 44 with protect stopper plate 45 and link to each other, protect stopper plate 45 and be provided with through hole 46, when arm plate 42 rotated with lock core inner bag 23, pivot pin 41 drivening rods 43 on it moved up, and promoted to protect on the stopper plate 45 simultaneously to move, keyhole 5 that through hole 46 is aimed at protect on the lock housing and the lockhole on the security door, then just open safe- guard door lock 6,61 with same key 3 and be the mechanical billiard on the lock 6,62 are the magnetic bullet on the lock 6,7 is the handle handle, and 8 for protecting the lock housing hold-down nut.
