Abstract

The utility model relates to a novel vehicle anti-theft lock. The structure is that a lock hole is opened on a lock body, the end portion of a U-shaped lock rod is inserted in the lock hole, the lock body is a straight rod shape, and is provided with a center hole which is communicated to the lock hole, one end of the lock body is open, a section of internal threads is arranged in the center hole, and a locking pin with external threads is rotated into the center hole. A lock core is fixed in the opening end of the lock body, and the front end of a shifting plate which is connected in the inner end of the lock core is inserted in a slot of the locking pin. The novel vehicle anti-theft lock uses the locking pin as a locking element, has large locking strength, strong damage resistance ability, and excellent security roles for various stealing ways, firm structure and convenient usage, can effectively reduce the stealing cases of bicycles or electric bicycles, and is beneficial for the harmony and security of society.

Description

The novel automobile theftproof lock

Technical field

The utility model relates to the lockset that uses on a kind of bicycle or the electric bicycle, specifically a kind of novel automobile theftproof lock.

Technical background

A kind of lockset that uses on bicycle or electric bicycle at present includes lock body and U-shape lock bar two parts.The lock body of this lockset is the flat-square shaped shape, has lockhole on it.The U-shape lock bar passes vehicle frame and wheel from a side of bicycle or electric bicycle wheel, and the lockhole of the lock body that is arranged in the wheel opposite side is inserted in its end.Locking mechanism in the closed lock body can be positioned at the U-shape lock bar in the lockhole of lock body, thereby pins bicycle or electric bicycle.But because the intensity of locking mechanism in this lock body is not high, easily destroyed and open lockset, robber's car case of Yin Faing still happens occasionally at present thus, has brought certain adverse influence to the common people's stable life.

The utility model content

The purpose of this utility model just provides a kind of intensity height, novel automobile theftproof lock that theftproof performance is good, to reduce the generation of bicycle or the stolen case of electric bicycle effectively.

The utility model is achieved in that a kind of novel automobile theftproof lock, has lockhole on lock body, and insert in the lockhole end of U-shape lock bar; Lock body is a direct rod shape, the one end opening, and have centre bore to be communicated in the lockhole, and in centre bore, be provided with one section internal thread, be provided with externally threaded lock pin and be screwed in the centre bore; Be fixed with lock core in the openend of lock body, the front end that is connected on the plectrum of lock core inner end inserts in the slot of lock pin.

After key inserted in the keyhole on the lock core, key can drive the plectrum of inner end and follow together rotation with the plectrum front end lock pin that cooperates of pegging graft by lock core.Because lock pin is screwed in the lock body centre bore by screw thread, therefore in the continuous rotation process of key, lock core, plectrum and lock pin, move with regard to having the front and back position of lock pin in centre bore---when the lock pin forward facing position moves in the lockhole that communicates with the lock body centre bore, just the leading section locking of the U-shape lock bar in the lockhole can be realized locking; Otherwise, when lock pin when the position moves in the centre bore that all is withdrawn into lock body backward, just the leading section of the U-shape lock bar in the lockhole can be discharged, realize unblanking.

The utility model with by be threaded and the lock pin that can move forward and backward as the locking piece in the lock body locking mechanism, its locking intensity is big, anti-damage ability is strong.The particularly centre bore setting of the lock body of direct rod shape design and internal thread is stirred the front and back position of realizing big distance down for lock pin continuously at plectrum and is moved possibility is provided.Key of the present utility model just is this.

The utility model is because lock body and locking bar part is all thicker, and lock core partly is positioned at the openend of lock body, therefore have stronger anti-ly pound, anti-anti-theft feature such as cut.If lock core is drilled, also just can not rotate plectrum and lock pin again, also just can not again lock be opened naturally, so the utility model also has anti-drilling anti-theft feature.The utility model all has preventive effect preferably to multiple theft mode, and sound construction is easy to use, can reduce the generation of bicycle or electric bicycle larceny case effectively, and the harmony that helps lend some impetus to society is stable.

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

Description of drawings

Fig. 1 is a structural representation of the present utility model.

The specific embodiment

As shown in Figure 1, this novel automobile theftproof lock has shaft-like always lock body 1, has two lockholes on lock body 1, with two leading sections of grafting U-shape lock bar 8.Also the left front end of U-shape lock bar 8 can be rotatably connected in the left lockhole of lock body 1, and the right lockhole of lock body 1 is made for the form that side is opened.Like this, U-shape lock bar 8 is connected on the lock body,, realizes the discrepancy of locking bar right front ends in the right lockhole of lock body by rotating rod lock 8.

Right-hand member at lock body 1 is provided with opening, and has centre bore to be communicated in the right lockhole; In centre bore, be shaped on one section internal thread 9.The front end of lock pin 2 is slightly thin polished rod, and the shank at rear portion is got on the bus and is shaped on external screw thread, and also has the center slot 3 of after-opening on shank 2.Shank 2 is screwed in the centre bore of lock body 1.Lock core 6 is housed in the openend of lock body 1, and retainer ring 5 of welding can be fixed on lock core in the openend of lock body in the lock body openend before lock core.Lock core 6 preferably adopts the cross anti-theft lock, anti-ly dials, chooses performance with what improve lockset.Be connected to plectrum 7 in the inner end of lock core 6, plectrum 7 stretches in the centre bore of lock body 1, in the slot 3 on its front end insertion lock pin 2.Like this, lock pin 2 can rotate with lock core 6 in company with plectrum 7.

Because being lock pin 2, one of characteristics of this novel lockset can realize in the centre bore of lock body 1 that the front and back position of big distance moves, and therefore can leave a jack radially in the end of locking bar 8, in order to the front end polished rod part of cross-under lock pin 2.The locking intensity of lockset is increased substantially, and anti-damage ability obviously strengthens.

As shown in Figure 1, the utility model also can protect the inclined-plane that the openend of lock body 1 is arranged to protract along 4, so just can make the spacing between the lockhole on lock body 1 opening end edge periphery and the lock core is a variable, can suppress pirate of the open behavior thus effectively, thereby further improve the theftproof performance of this lockset the instigation rotation of lock core enforcement.
