Abstract
The utility model relates to a theft-proof lock for a bicycle, which comprises a U-shaped lock frame and a straight-rod lock bolt. The open end of the U-shaped lock frame is respectively provided with a lock bolt sleeve for locking and positioning and a lock core assembly; one end of the straight-rod lock bolt is provided with an unlocking positioning part of the lock bolt, and the corresponding position on the side edge of the U-shaped lock frame is provided with a positioning part matched with the unlocking positioning part of the lock bolt; one end of the straight-rod lock bolt is provided with an unlocking positioning clamp spring of the lock bolt; the upper side edge of the U-shaped lock frame is provided with a positioning groove; one side of the lock core assembly is extended with a positioning open groove of the straight-rod lock bolt. As both ends of the straight-rod lock bolt of the utility model are respectively provided with a positioning structure, the positioning is exact and firm, and the use is more convenient; in addition, the structure is simple and reasonable, and the processing and the assembly are easy.
Description
The utility model relates to a kind of anti-theft lock for bicycle, also applicable to motorcycle and tricycle.
Existing anti-theft lock for vehicle kind is more, structure is different.As No. 98233694.2, Chinese patent disclosed " anti-theft lock for vehicle ", it comprises U-shape lock frame and straight-bar locking bolt, the locking bolt sleeve of the intrinsic locking location, one termination of U-shaped lock frame, the other end of its U-shaped lock frame be articulated and connected fastener and tapered end sleeve, tapered end assembly and straight-bar locking bolt by rise simultaneously unblank and the spacing pin of locking fuse, can rotate around swivel pin after unblanking, can in locking bolt sleeve and tapered end sleeve, endwisely slip when opening and closing lock.Be provided with tapered end assembly location U-shaped reed between its connection fastener and the tapered end sleeve, it unblanks the back by U-shaped reed location.For strengthening theftproof, the diameter of existing straight-bar locking bolt constantly increases slightly, the also corresponding increase of weight, existing U-shaped reed is because of its structure and the difficult location of elastic force restriction, particularly reed uses after a period of time and when travelling on the uneven road of jolting, and may take place that the straight-bar locking bolt breaks away from the control of U-shaped reed and the accident of blocking wheel.
The purpose of this utility model aims to provide a kind of simple and reasonable, firm position, anti-theft lock for bicycle easy to use, to overcome the deficiencies in the prior art.
Anti-theft lock for bicycle by this purpose design, comprise U-shaped lock frame and straight-bar locking bolt, the openend of U-shaped lock frame is respectively arranged with the locking bolt sleeve and the lock core assembly of locking location, its architectural feature is that an end of straight-bar locking bolt is provided with the locking bolt keeper of unblanking, and the side relevant position of U-shaped lock frame is provided with the keeper that matches.
One end of described straight-bar locking bolt is provided with locking bolt and unblanks to locate jump ring, and the upper side edge relevant position of U-shaped lock frame is provided with the detent that matches.The straight-bar locking bolt is the hollow stem slidingtype, and an end is provided with jump ring location lid.The straight-bar locking bolt also can be the solid hopkinson bar slidingtype, and the location jump ring is riveted on an end of locking bolt.One side of described lock core assembly is extended straight-bar locking bolt locating aperture groove.Described keeper also can be the mutual alignment pin of chucking/collude/block/projection.
The two ends of straight-bar locking bolt of the present utility model are provided with the location structure of unblanking, and make its accurate positioning firm, use more convenient, and simple and reasonable, process and assemble is easy.
