Description

Safety anti-theft lock

Technical field

The utility model belongs to lock class technical field, particularly a kind of theftproof lock that has lock pin that is converted by padlock.

Background technology

The lock class is used very extensive in actual life, especially for padlock, is widely used in the safety lock of gate and vehicle.Being seen padlock mainly is made up of lock body and lock bridge on the market now, and lock bridge stretches in the lockhole, finishes locking.But the padlock of this kind structure after the locking, is very easily pried open, and poor safety performance has influenced the safety of vehicle and family.

Though occurred diversified lock now, found no the lock that padlock and lock pin combine by retrieval.

Summary of the invention

The purpose of this utility model is to provide a kind of padlock and lock pin to combine, the novel safety anti-theft lock that is locked by lock pin.The utility model adopts following technical proposals for this reason: a kind of safety anti-theft lock, mainly form by padlock, it is characterized in that: also include an outer valve jacket that can insert above-mentioned padlock, the bottom of valve jacket is provided with opening outside, valve jacket is provided with a cross-drilled hole outside, is provided with a dead bolt that has groove on the lock body between two lockholes of padlock; Also include a lock pin that can insert in the above-mentioned cross-drilled hole, lock pin is provided with the spill annular groove that matches with groove on lock bridge and the dead bolt.After the utility model adopted technique scheme, owing to set up valve jacket outside on the basis of former padlock, padlock was finished outside locking by the locking lock pin by lock pin simultaneously.Has effect simple in structure, easy to use, easy to maintenance.Former padlock by with a kind of novel kayser of being combined into of lock pin.Padlock is wrapped in the firm outer valve jacket, and its impact capacity of bearing external force is strengthened greatly, can bear the external impacts of various directions.Can't pry open simultaneously, also can't carry out sawed-off, destruction, strengthen antitheft, tamper-resistant function, can be widely used in the locking of motor vehicles and family's door from the outside to lock body.

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.
