Abstract
The utility model relates to a bicycle lock acting with the arm braces, and has a housing, a tapered ned and a lock core which are inside the housing, and arm braces which are arranged at the outside of the housing. The utility model is characterized in that the gear acting with the arm braces and the spiral pieces on the gear shaft meshing with the gear connect with the tapered ned; one side of the tapered ned is provided with grooves perpendicular to the axes, and the breadth of the grooves is a little bigger than the thickness of the spiral pieces; the gear acting with the arm braces is a fan leaf gear greater than 90 degree. The utility model makes the bicycle lock acting with the arm braces and has the advantages of simple and reasonable structure, easy manufacture, novel design, reliable using, etc., also effectively prevents the matter of the bicycle being forced, and avoiding the bicycle being stolen due to the negligence of not locking well.
Description
Technical field
The utility model relates to a kind of bicycle lock, especially relates to bicycle lock a kind of and the spike interlock.
Background technology
Known bicycle lock is the shape of a hoof, generally is installed on the vehicle frame of bicycle rear, pins wheel Radiation bar with lock pin, and trailing wheel can not be rotated, and reaches the application target of lockset.The shortcoming one of this kind conventional lock is to be easy to be prized, the 2nd, and be two independently actions because spike is supported in parking with the lock lock, so after spike has been supported in parking, be easy to forget lock is pinned, give opportunity of auto theft person because of carelessness.China Patent No. 95244551.4 " a kind of bicycle lock that links with back pole-bracket ", comprise lock body, back pole-bracket, drive spindle and dead bolt are installed on lock body, when the drive spindle up-and-down movement, move in the skewed slot of protruded stigma on the drive spindle on dead bolt, make the motion of dead bolt occurred level, back pole-bracket comprises fixed support and movable pin, on movable pin, there is hitching post to connect, drive spindle is moved along with stirring up and down of movable pin with drive spindle.The shortcoming of above-mentioned patent is a complex structure, and link is many, the productive costs height.
Summary of the invention
The utility model main purpose is at above-mentioned deficiency, thereby designs a kind of bicycle lock that links with spike that adopts, and to solve complex structure, the interlock link is many, the technical matters that productive costs is high.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals: have shell, there is tapered end the inside, lock core, link gear, there is the spike of interlock with it the outside, it is characterized in that: described link gear be with the gear of spike interlock and with the axle of its gears in mesh on flight is arranged, the groove on its flight and the tapered end is commissure mutually; The gradient of groove and width match with flight.
As preferably, described gear with the spike interlock is the sector gear greater than 90 ° of angles.
Therefore, the utility model is the interlock of spike and bicycle lock, has simple and reasonable for structurely, easily manufactured, novel, uses characteristics such as reliable, and problem such as prevent that effectively bicycle from being prized has also been avoided because of neglecting not with the good bicycle theft that causes of lock.
Description of drawings
Accompanying drawing 1 is a kind of structure front schematic view of the present utility model;
Accompanying drawing 2 is a kind of texture edge scheme drawings of the present utility model.
The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is further described in detail.
Embodiment: as shown in Figure 1 and Figure 2, tapered end 8, linkages such as lock core 2 and gear 7,4 are installed among the shell 5, mesh with gear 4 again with the sector gear 7 of spike 6 interlocks, on the axle 9 of gear 4, flight 3 is housed, flight 3 matches with groove on the tapered end 8, and the tapered end 8 of present embodiment is a round section, also can be rectangle, square or other odd-shaped cross section in the practical application; As shown in the figure, angled with 49 of gears with the sector gear 7 and the axle 10 of spike 6 interlocks, its degree of dip is decided by the factors such as width of shell 5; Be illustrated as the state that spike 6 does not put down, that is the state of tapered end 8 when not stretching to the steel ring spoke.
During use, when spike 6 puts down, with spike 6 coaxial and the sector gear 7 of interlock and gear 4 rotations that are engaged with, drive flight 3 rotations that cooperate with tapered end 8 on the axle 9, flight 3 revolve liter, it is protruding from horizontal direction to promote tapered end 8, and exceeds steel ring abutting end spoke position; The connecting rod 1 that links to each other, acts on the tapered end 8 with lock core 2 fastens tapered end 8, makes tapered end 8 locking that fixes; The connecting rod 1 that links to each other with lock core 2 also can act on the sector gear 7, and it can not be rotated, and plays equally to make tapered end 8 locking that fixes.In the time will opening tapered end, key is put into lock core 2, make the connecting rod 1 that links to each other with lock core 2 throw off tapered end 8 or sector gear 7, mention spike 6, this moment, tapered end 8 was withdrawn automatically, finished the unlatching of tapered end 8.The utility model can be installed in the position of bicycle bottom rail near rear axle.
