Description
Technical field
The utility model belongs to bicycle lock, is specifically related to a kind of bicycle lock of rope-locking type.
Background technology
China is bicycle big country, then also will be a lot of relative to the Structural Development of the various parts of bicycle, such as bicycle lock, bicycle lock is divided into two kinds substantially, a kind of is bayonet type, a kind of is rope-locking type, namely so-called rope-locking type adopts lock rope as connector, can the use length of prolongation bicycle lock of amplitude peak, but the structure of the bicycle lock of most rope-locking type is all relatively complicated, and lack recovery capacity in the position of latch fitting, in use, the problem easily occurring due to rigidity causes the damage of latch fitting.
Summary of the invention
The utility model in order to solve the technical problem mentioned in background technology, then provides a kind of bicycle lock of rope-locking type.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
A kind of bicycle lock of rope-locking type, comprise lock rope, lock rope one end connects the output of lock core, the input of lock core is provided with lock bolt sleeve successively, dead bolt and torsion spring, the other end of lock rope is provided with pin, the side of lock core is provided with pin patchhole, the output of dead bolt is provided with cylinder and installs projection, the link that projection installed by torsion spring and cylinder is provided with first supporting leg, what projection end face installed by cylinder is provided with for the locating slot with the suitable installation of the first supporting leg, the other end of torsion spring is provided with the second supporting leg, second supporting leg is connected with lagging, the head of pin is circular platform type, the lower head of pin is provided with a circle groove, pin inserts pin patchhole, lagging inserts the side of a circle groove of pin.
The circular platform type head and one of pin encloses between groove as inclined-plane is connected.
The input of lock bolt sleeve is provided with key insertion hole, and the output of lock bolt sleeve is provided with connection projection, and lock bolt sleeve is rotationally connected by connection projection and dead bolt.
Lagging and the connection side of the second supporting leg are provided with the groove for being connected with the second supporting leg.
After adopting above technical scheme: adopt lock bolt sleeve successively from outside to inside, dead bolt, torsion spring, lock core, the structure of lock rope and plug, compare prior art, the utility model realizes conversion connection status in junction by torsion spring-lagging, namely when pin inserts pin patchhole, lagging inserts in the side of the groove of pin, then rotational lock core is passed through, drive torsion spring, torsion spring drives lagging to rotate, then lagging rotates thus compression torsion spring, the circular platform type head and one that then lagging rotated pin encloses the inclined-plane between groove, at this time pin then can freely leave pin patchhole, structure of the present utility model is simple, and it is easy to use.
Accompanying drawing explanation
Fig. 1 is structure sectional view of the present utility model.
Detailed description of the invention
See Fig. 1, a kind of bicycle lock of rope-locking type, comprise lock rope 1, lock rope 1 one end connects the output of lock core 2, the input of lock core 2 is provided with lock bolt sleeve 3 successively, dead bolt 4 and torsion spring 5, the other end of lock rope 1 is provided with pin 6, the side of lock core 2 is provided with pin patchhole 7, the output of dead bolt 4 is provided with cylinder and installs projection 8, the link that projection 8 installed by torsion spring 5 and cylinder is provided with first supporting leg 9, what projection 8 end face installed by cylinder is provided with for the locating slot 10 with the suitable installation of the first supporting leg 9, the other end of torsion spring 5 is provided with the second supporting leg 11, second supporting leg 11 is connected with lagging 12, the head 13 of pin 6 is circular platform type, a circle groove 14 is provided with below the head 13 of pin 6, pin 6 inserts pin patchhole 7, lagging 12 inserts the side of a circle groove 14 of pin 6.
All parts of the present utility model is explained:
1) the circular platform type head 13 and of pin 6 encloses between groove 14 as inclined-plane is connected;
2) input of lock bolt sleeve 3 is provided with key insertion hole, and the output of lock bolt sleeve 3 is provided with and connects projection 15, and lock bolt sleeve 3 is rotationally connected with dead bolt 4 by connecting projection 15.
3) lagging and the connection side of the second supporting leg are provided with the groove 16 for being connected with the second supporting leg.
The beneficial effects of the utility model: adopt lock bolt sleeve successively from outside to inside, dead bolt, torsion spring, lock core, the structure of lock rope and plug, compare prior art, the utility model realizes conversion connection status in junction by torsion spring-lagging, namely when pin inserts pin patchhole, lagging inserts in the side of the groove of pin, then rotational lock core is passed through, drive torsion spring, torsion spring drives lagging to rotate, then lagging rotates thus compression torsion spring, the circular platform type head and one that then lagging rotated pin encloses the inclined-plane between groove, at this time pin then can freely leave pin patchhole, structure of the present utility model is simple, and it is easy to use.
