The specific embodiment
The utility model embodiment comprises in order to be connected in the lock body 1 and the lock bridge cover 2 that is connected on the front fork opposite side pillar on front fork one lateral brace, lock body is provided with lock core 3 and can inserts the lock bridge 4 of lock bridge cover, it is characterized in that: the perisporium of lock bridge inner end 5 is provided with limited impression 6, described lock core is connected with fork 7 on radially, and the upper end 8 of this fork is embedded in the limited impression of lock bridge and slides with the restriction lock bridge.
For the ease of just can be when lock bridge moves into place with on the bicycle front fork automatic locking, the sidepiece of above-mentioned fork is provided with recessed joint 9, the end that is connected in the elastic wire 10 of fork side embeds in the recessed joint of fork and resets to control it, the middle part of elastic wire is provided with the spacing snap ring 11 that limits its swing, when lock bridge moves into place, elastic wire inwardly compresses fork under the effect of its elastic force and spacing snap ring, force fork to be embedded in the limited impression of lock bridge, and lock bridge is locked.Described lock bridge front side is provided with and pushes away handle 12, and this head that pushes away handle passes the conduit of offering the lock body front side 13 and reaches lock body the place ahead, is convenient to people during use and moves forward and backward by pushing away handle promotion lock bridge.
In order further to improve theftproof performance, be plugged with the key 14 of its rotation of control on the above-mentioned lock core, be hinged with licence plate 15 on the key, this licence plate be turned to surface of lock body on groove surface 16 when fitting, the numeral 17 on its board face forms an integral body with numeral 18 on the surface of lock body.Like this, when key is pulled up, the numeral on the surface of lock body is just incomplete half.This device matches with the grade of steel of mint-mark on vehicle body, in case lock is prized, the robber is difficult to configure and the corresponding licence plate of surface of lock body numeral, thereby is recognized easily.
In order to prevent thief's picking lock, above-mentioned lock body connects on the pillar that is locked at front fork one side with the tight locking button 20 of its rear lateral portion through the bolt connection part 19 that Carburization Treatment is crossed, described lock bridge cover is made of preceding hasp and the back hasp that the middle part has lock bridge perforation 21, and it is preceding, back hasp is locked on the front fork opposite side pillar through bolt connection part 22 connections, the head of described bolt connection part has diameter passes through hole 23 greater than bolt shoulder 24, afterbody passes bolt and passes through hole and connect with nut head 25, the outer end of described shoulder is provided with bolt tappet head 26, has the less axle journal of diameter 27 between bolt tappet head and the shoulder.The user when mounted, adopt spanner 28 rotating bolt tappet heads, when bolt connection part is tightened, continue firmly rotating spanner, because the diameter of axle journal is less, the moment that spanner turns has surpassed the stress that axle journal can bear, the bolt tappet head is twisted into two parts from axle journal, bolt can not reversely be back-outed, and the lock body once mounting puts in place, and so present road thief all tools used in crime commonly used all can't unload it.
For the ease of difference, the numeral of above-mentioned surface of lock body is filled in the spill font hole of surface of lock body by the coating of two kinds of different tones, wherein a kind of numeral of tone is engraved on the surface of lock body fully, the first half of the numeral of another kind of tone is engraved on the surface of lock body, and the latter half is engraved on the license surface.Like this when font is incomplete, whether by the contrast of two kinds of tones, allowing the people find vehicle easily is to steal and come.And, can scribe this bicycle location and tax revenue sign thereof above the surface of lock body so that people's identification prevents the trans-regional car incident of stealing.
In addition, the rear lateral portion of above-mentioned lock body is provided with the cover plate 29 in order to sealing lock body middle part cavity, and this cover plate is plugged in the set grafting line of rabbet joint in lock body rear portion by the one sidepiece, and the outside of this cover plate is pressed on the lock body by the tight locking button that is connected in the lock body rear lateral portion.Because after the lock body once mounting put in place, lock body can not separate with the tight locking button at its rear portion again, makes cover plate to be pried open.
