Description
Technical field
The utility model relates to lockset, specifically a kind of double lock tongue chain lock that is used for motorcycle, electric motor car, bicycle.
Background technology
Existing motorcycle, electric motor car, bicycle lock generally have three kinds of form of structure, and a kind of is the annular enclosed type structure, second kind be cross-latch type (do not seal, structure, the third is a chain structure.The annular enclosed type bicycle lock generally is installed on the mud breeches pipe under the bike saddle saddle, is mainly used in the trailing wheel of lock bicycle, and the cross-latch type bicycle lock is installed on the front fork tube of bicycle, is mainly used in the front-wheel of lock bicycle.The common drawback of these two kinds of bicycle locks is, only is applicable to the self-locking of single bicycle, and can not realizes the interlocking of many bicycles, perhaps bicycle and certain stay hook (interlocking of railing, electric pole etc., thereby theftproof performance is relatively poor.Though the chain type bicycle lock can solve the interlocking problem of many bicycles, the chain of locking owing to bolt is very easily destroyed by pliers one class hardware ﹠ tools, so antitheft reliability is relatively poor.In addition, these three kinds of bicycle locks also exist locking bar and lock body is inseparable, dead bolt is single, when unblanking, the car key symbol rotates to an angle, the shortcomings such as the back key can not take out of unblanking, like this, not only tie the user and brought inconvenience, and influenced the reliability of lock and the application life of lock.The patent No. is that 92215828 Chinese patent discloses a kind of push-down double lock tongue theftproof lock, form by lock body, locking bar and lock body socket, it is characterized in that this lock body and locking bar are separate type, on lock body, be provided with two locking bar jacks, be provided with dead bolt and spring in the locking bar jack, in lock body, be provided with one and be used to control the push rod that dead bolt is opened, an end of push rod is connected with lock core by bolt.The lock body of this theftproof lock and locking bar adopt separate type, and locking bar adopts U type structure, and the two ends of U type structure are provided with locked groove, be provided with double lock tongue in the lock body, the push-down control mode is adopted in the unlatching of dead bolt, promptly as long as key is inserted in the lock core, inside one pushes away, and can open lock.This theftproof lock performance be better than above-mentioned lockset, but still have following deficiency: it has only a lock core, by a lock core control double lock tongue, destroyed when lock core, double lock tongue is just ineffective.Therefore, its antitheft effect is still limited.In addition, lock body and locking bar adopt separate type, and inconvenience is in use arranged more.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of theftproof performance better and double lock tongue chain lock easy to use.
The utility model solves the problems of the technologies described above the technical scheme that is adopted:
A kind of double lock tongue chain lock, comprise the cylindricality lock body, one end and the described lock body of one U-shape sword iron are hinged, the other end of U-shape sword iron is the tapered end part, in the end of lock body first lock core is set, is provided with rotating lock tongue in described first lock core, it is characterized in that: second lock core is set on lock body, be provided with the slip dead bolt in described second lock core, the tapered end of described U-shape sword iron partly has first locked groove and second locked groove that holds rotating lock tongue and slip dead bolt respectively.
For optimizing technique scheme, the measure that the utility model is taked also comprises:
The axis of the axis of described second lock core and first lock core is spent at an angle of 90.
Be provided with the flexible spring of control slip dead bolt in described second lock core, the head of slip dead bolt has wedge structure.
Be connected with chain on described lock body, an end of chain is connected with the chain ring that can be placed on the U-shape sword iron;
First locked groove of described tapered end part is opposite with the opening direction of second locked groove, and staggers up and down.
Because the utility model has adopted above-mentioned technical measures, making it to contrast prior art has following advantage:
1, independently be provided with twin-lock core and double lock tongue, safety factor doubles;
2, on a tapered end, be provided with first locked groove and second locked groove that holds rotating lock tongue and slip dead bolt respectively, make the structure of lockset very compact;
3, U-shape sword iron one end and lock body are hinged, and the U-shape sword iron other end is the tapered end part, and the switch lockset is convenient;
4, the setting of chain makes it not only can to realize the self-locking to the single vehicle any part, and can realize the interlocking to many cars, and the interlocking of car and fixture.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
The structural representation of lock core part when Fig. 2 is the utility model embodiment lockset opening.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
With reference to Fig. 1, the utility model comprises that an end 2 of cylindricality lock body 4, one U-shape sword irons 1 is hinged by pin 3 and lock body 4.The other end of U-shape sword iron 1 is a tapered end part 12, and tapered end part 12 has two locked grooves, holds first locked groove 17 and second locked groove 13 of rotating lock tongue 16 and slip dead bolt 7 respectively.The opening direction of first locked groove 17 and second locked groove 13 is opposite, and staggers up and down, to increase the intensity of tapered end part 12.Be provided with in first lock core, 14, the first lock cores 14 in the end of lock body 4 cylinders and be provided with rotating lock tongue 16.Second lock core 11 is set on the cylinder of lock body 4 in addition.The axis 19 of second lock core and the axis 18 of first lock core are spent at an angle of 90.Be provided with slip dead bolt 7 in second lock core 11, the spring 8 in the lock core is controlled the flexible of slip dead bolts 7.The head of slip dead bolt 7 has wedge structure 9, is convenient to when closing tapered end part 12, and slip dead bolt 7 can enter in second locked groove 13 automatically.Be connected with chain 6 on lock body 4, an end of chain 6 is connected with the chain ring 5 that can be placed on the U-shape sword iron 1.
During use, the slip dead bolt 7 of the tapered end part of closing 12, the second lock cores 11 enters under the effect of spring 8 in second locked groove 13, will lock locking.Key 15 with first lock core inserts in first lock core 14 again, rotates the key 15 of first lock core, and rotating lock tongue 16 is screwed in first locked groove 17, will lock locking once more, forms a chain of locking, and the safety of lockset increases greatly.When unblanking, the key 15 of first lock core is inserted in first lock core 14, the key 15 of backward rotation first lock core, rotating lock tongue 16 is screwed out in first locked groove 17, key 10 with second lock core inserts in second lock core 11 again, rotate the key 10 of second lock core, the effect that overcomes spring 8 withdraws from slip dead bolt 7 from second locked groove 13.At this moment, U-shape sword iron 1 can be rotated around pin 2, open U-shape sword iron 1 and unblank.The key 10 of second lock core also can take off when slip dead bolt 7 openings, and the key 15 of first lock core can not take off when rotating lock tongue 16 openings.Also the chain 6 that is connected with lock body 4 can be enclosed within on many cars or be enclosed within on the fixture, the chain ring 5 that will be connected in chain 6 one ends then is enclosed within and realizes interlocking on the U-shape sword iron 1.
