Description of drawings
Fig. 1 is a kind of structural representation of the present utility model, and Fig. 2 is the structural representation of outer valve jacket shown in Figure 1, and Fig. 3 is the structural representation of lock pin shown in Figure 1, and Fig. 4 is the structural representation of padlock shown in Figure 1.
The specific embodiment
In the accompanying drawing, 1 be padlock, 2 for outer valve jacket, 3 for cross-drilled hole, 4 for dead bolt, 5 for lock pin, 6 for the spill annular groove, 7 for shift fork, 8 for lock bridge, 9 for projection, 10 for the attacker.As shown in drawings, the utility model safety anti-theft lock is to convert on the basis of former padlock 1, mainly is made up of former padlock 1, outer valve jacket 2 and lock pin 5, and padlock 1 is provided with unlatching with key and lockhole, lock bridge 8.Above-mentioned lock pin 5 is designed to cylindrical, and this lock pin 5 is made up of lock, the spill annular groove 6 and the attacker 10 that match with above-mentioned lock bridge 8, and lock is used for externally locking, and attacker 10 can make things convenient for the taking-up of lock pin 5; During locking, the lock bridge 8 of padlock 1 just in time is positioned at above-mentioned spill annular groove 6, by the locking of spill annular groove 6 being finished the locking of lock pin 5.Above-mentioned outer valve jacket 2 is an empty capsid in the square steel, and the size of its inner chamber and padlock 1 adapt, and the bottom of this outer valve jacket 2 is provided with opening, and above-mentioned padlock 1 can stretch in the outer valve jacket 2 by this opening; Also be provided with a cross-drilled hole 3 outside on the valve jacket 2, the position of this cross-drilled hole 3 is corresponding with formed hole, padlock 1 closed back.Be provided with a dead bolt 4 that has groove on the lock body between 1 two lockholes of above-mentioned padlock, this dead bolt 4 is designed to circular arc; During padlock 1 locking, lock bridge 8 forms a circular hole with dead bolt 4, and this circular hole just in time matches with spill annular groove 6 on the above-mentioned lock pin 5, makes that the spill annular groove 6 on the lock pin 5 is stuck on lock bridge 8 and the dead bolt 4, moving forward and backward of locking lock pin 5, thus reach the purpose that locks lock pin 5.Lock pin 5 can penetrate door and go up in the hole of reserving, and also can directly penetrate position, motor vehicle institute lock section, finishes locking.The top of valve jacket 2 also is provided with a rotating shift fork 7 outside, and this shift fork 7 is designed to U-shaped.Under the normal condition, this shift fork 7 is parallel with lock bridge 8, and when the padlock 1 of valve jacket 2 needed locking outside being positioned at, the above-mentioned shift fork 7 of lateral rotation made shift fork 7 perpendicular to lock bridge 8, is used to stop lock bridge 8, firmly, can finish the locking of padlock 1 in padlock 1 bottom.
For increasing tamper-resistant function of the present utility model, the Cross-section Design of the lock bridge 8 of above-mentioned padlock 1 is square, like this when lock bridge 8 locking lock pins 5, cooperates firm between lock pin 5 and the lock bridge 8.
On two sidewalls of the inside at above-mentioned cross-drilled hole 3 places, be respectively equipped with projection 9, make cross-drilled hole 3 extend internally, lock bridge 8 can insert in two spaces between the projection 9 simultaneously, thereby guaranteed fully contacting between lock bridge 8 and the outer valve jacket 2, avoid external impact force to reach lock body, thereby guaranteed the firm performance of this lock.
During locking, at first padlock 1 is stretched in the outer valve jacket 2, make that hole that lock bridge 8 and lock body surround and cross-drilled hole 3 on the outer valve jacket 2 are corresponding, insert lock pin 5 by cross-drilled hole 3 then, make spill annular groove 6 on the lock pin 5 between lock bridge 8 and dead bolt 4, lock pin 5 was inserted in door and went up in the hole of reserving or the latched position of motor vehicle this moment; Rotate shift fork 7, make shift fork 7 withstand on the lock pin 5, the opening by outer valve jacket 2 bottoms upwards promotes padlock 1, and promptly the lockable padlock 1, thus locking lock pin 5.During unlatching, at first open padlock 1, rotate shift fork 7 then, can extract lock pin 5 out.When not needing to lock, lock pin 5 oppositely can be inserted in the cross-drilled hole 3, be locked on the outer valve jacket 2 by padlock 1 again, prevent losing of padlock 1 and lock pin 5.
