Abstract
A novelcross bolt type theft-proof lock for a bicycle of the utility model is provided. A cross bolt is arranged in the groove of a lock body, one end of a spring drive machine member which is installed on the lock body is clamped in the lock body, and the other end of the spring drive machine member is connected to the cross bolt. A groove is arranged on the cross bolt, when the novelcross bolt type theft-proof lock for a bicycle is in a locking status, the part of the lock body corresponding to the groove arranged on the cross bolt is provided with a bolt, the bolt is connected to a lock core installed on the lock body, the bolt stretches and contracts with the turning of the lock core, a small spring is provided between the bottom and the lock body, and the lock body is closed over by an outer shell. Because the spring is adopted to be as a driving element, the structure is simple and practical, the movement of each component is flexible, stuck and rusted phenomena can not occur, and the theft-proof ability is greatly enhanced.
Description
The utility model relates to a kind of lockset, especially anti-theft lock for bicycle.
The kind of existing bicycle lock is a lot, at present newer a kind of be the horizontal bolt-lock of tooth bar.Gear, tooth bar are arranged in this lock, rotate by gear and drive horizontal bolt, play the effect of unlatching or locking.But the mechanical part of this lock is loaded down with trivial details, processing difficulties, and the opening and closing operations underaction is convenient, also is prone to stuck fault.
The purpose of this utility model provides a kind of novel cross-latch type anti-theft lock for bicycle, and it is simple and practical, and each parts flexible movements is easy to processing, and safe and reliable.
The purpose of this utility model is achieved in that on lock body [ 2 ] opens a groove, horizontal bolt [ 3 ] is housed in the groove, spring transmission device [ 4 ] is contained on the lock body [ 2 ], the one end is stuck in the lock body, the other end links to each other with horizontal bolt [ 3 ], spring transmission device [ 4 ] both can adopt torsional mode, also can adopt compression.One end of horizontal bolt [ 3 ] has a groove, and dead bolt [ 5 ] is equipped with at lock body position corresponding with horizontal bolt groove during locking states, and dead bolt [ 5 ] links to each other with lock core [ 6 ] on being contained in lock body [ 2 ], and stretches with the rotation of lock core [ 6 ].Between the bottom of dead bolt [ 5 ] and the lock body [ 2 ] little spring [ 7 ] is arranged.Shell [ 1 ] one end and lock body [ 2 ] join, and it is covered, and the other end is fluted, and horizontal bolt [ 3 ] is inserted in this groove during locking states.
The twisting key, lock core [ 6 ] rotates and makes in the dead bolt [ 5 ] and contracts, and just can utilize the elastic force of spring transmission device [ 4 ] to drive horizontal bolt [ 3 ] to the enable possition, thereby open lock.During locking, only need horizontal bolt [ 3 ] is applied external force greater than spring transmission device [ 4 ] elastic force, make horizontal bolt [ 3 ] slide to locked position, dead bolt [ 5 ] ejects under the effect of little spring [ 7 ], block horizontal bolt groove, lock core [ 6 ] is replied, and can play the locking effect.
The utility model has been cancelled in the existing cross-latch type lock gear, tooth bar and the associated components in order to transmission, use spring instead and directly drive horizontal bolt, so lock of the present utility model, practicality simple for structure, be easy to processing, the dead phenomenon of becoming rusty the common jam of other pattern lock can not appear, in each parts flexible movements.
Each position component of lock of the present utility model all can be done bigger change, material has multiple choices, because movable part occupies little space, can also improve the design of other parts (can be single-casting) simultaneously, the anti-theft capability of lock is greatly strengthened as lock body.
Be the detailed description of drawings and Examples below.
Fig. 1 is an outline drawing of the present utility model.
Fig. 2 is the structural representation of this novel cross-latch type anti-theft lock for bicycle.
Fig. 3 is the side schematic view of this novel cross-latch type anti-theft lock for bicycle.
Among the figure: 1. shell; 2. lock body; 3. horizontal bolt; 4. spring transmission device; 5. dead bolt; 6. lock core; 7. little spring.
Among Fig. 1, lock is in locking states, and an end of shell [ 1 ] and lock body [ 2 ] join, and with the lock body capping, horizontal bolt [ 3 ] one ends that are contained in the lock body [ 2 ] insert in the groove of shell [ 1 ] other end.
Among Fig. 2, the solid line position of horizontal bolt [ 3 ] and spring transmission device [ 4 ] is a locking states, and dotted line position is an opening.Among Fig. 2, horizontal bolt [ 3 ] is housed in the groove on the lock body [ 2 ]; Spring transmission device [ 4 ], dead bolt [ 5 ], lock core [ 6 ] are contained on the lock body [ 2 ], and its medi-spring transmission device [ 4 ] is a torsional mode, and an end is stuck in the lock body [ 2 ], and the other end links to each other with horizontal bolt [ 3 ]; One end of horizontal bolt [ 3 ] is fluted, and dead bolt during locking states [ 5 ] can inject in this groove.Less for lock is taken up space when the opening, horizontal bolt [ 3 ] is preferably folding.
Among Fig. 3, dead bolt [ 5 ] links to each other with lock core [ 6 ], and little spring [ 7 ] is between dead bolt [ 5 ] and lock body [ 2 ].Lock body has a groove on [ 2 ], and horizontal bolt [ 3 ] is contained in this groove.
