Abstract
The utility model relates to an anti-prizing bicycle lock using the method of internal locking. The spring bodies of the lock core are arranged in the hole of the bracket of a lock body, a T-shaped keyhole is arranged in the lock core, and spring cavities which can be used for containing springs are arranged on the spring bodies on the two symmetrical ends of the keyhole respectively. A gear is arranged on a cylinder on the lower segment of the lock core, and the gear is engaged with a rack bar on a movable rod in the bracket of the lock body. The whole bicycle lock is arranged in the tube of a bicycle. A key is inserted in the keyhole to rotate the lock core, and a locking pin on the end of the movable rod locks or opens a front shaft or a centre shaft in the mode of a plug by the gear and the rack bar.

Description
The utility model relates to bicycle and constitutes one, can prevent a kind of lock of bicycle theft.
In the background technology field, lock and bicycle (or tricycle) itself all are a kind of independently products, are by mechanical attachment it to be combined, and play effects antitheft, security personnel.Recently the stolen case of bicycle is also more, and its main cause is that the thief often adopts and destroys lock or with the malfeasance of special tool used in crime unlatching lock, cause numerous bicycles stolen.In recent years, also there are many people to move brains, improve the structure of lock and spend the time up and down, once designed various theftproof locks, pick-proof car, but all do not tackle the problem at its root, do not obtain significant effect from lock.
The purpose of this utility model is: by hidden bicycle lock, lock is contained in the car pipe (the front and back cant beam of bike rack or crossbeam pipe) of bicycle, and locking front axle or axis, the pick-proof of raising lock finally reaches bicycle theft-prevention.
The technical solution of the utility model is: lock core and pellet shot from a slingshot body are installed in the hole of lock body support, have "T"-shaped keyhole in the lock core, on the pellet shot from a slingshot body of keyhole two symmetry ends the pin chambers that can shoot son is arranged respectively, on the cylinder of lock core hypomere gear is housed, it with the lock body support in an end have the tooth bar on the motion bar of lock pin to be meshed, whole lock is installed in the car pipe of bicycle." T " key inserts in the keyhole, rotational lock core, and the tooth bar on the gear driven motion bar makes the lock pin insertion front axle of motion bar one end (be meant to connect handlebar and front-wheel, and be enclosed within the steel pipe part in the bike rack pipe; The steel pipe part that promptly often is called front fork) in the lockpin hole, or locks in axis (be meant and drive the axle that the two steps are rotated) lockpin hole.
The utility model is compared with background technology, and the useful effect that has is:
1. because lock is hidden is installed in the car pipe, not readily removable sled, with other lock comparatively speaking, its safety improves;
2. when lock pin is locked in the angle of front axle lockpin hole setting, pushes the machine and to turn-take in the original place; When lock pin is locked in axis, the bicycle of then can't riding;
3. bicycle front axle and axis are critical component, if destroying lock, stolen to bicycle then become and do not have use value.
Therefore, this lock all can be promoted the use of on bicycle or tricycle.
Below in conjunction with accompanying drawing,, provide details of the present utility model by description to embodiment.
Fig. 1, A-A sectional view of the present utility model;
Fig. 2, front view of the present utility model;
Fig. 3, B-B sectional view of the present utility model;
Fig. 4, C-C sectional view of the present utility model;
Fig. 5, D of the present utility model are to view;
The structure chart of Fig. 6, motion bar;
The E of Fig. 7, motion bar is to view.
As Fig. 1, Fig. 2, Fig. 3, Fig. 4, shown in Figure 5, the pellet shot from a slingshot body 2 that the utility model will be equipped with lock core 3 is installed in the hole of lock body support 1, have "T"-shaped keyhole 9 in the lock core 3, in the pin chambers 4 on the pellet shot from a slingshot body 2 of 9 liang of symmetry ends of keyhole the two symmetrical groups pellet shot from a slingshot is arranged, one group of pellet shot from a slingshot is housed on the lock core 3, or the two symmetrical groups pellet shot from a slingshot is housed, gear 8 is installed on the lock core 3 hypomere cylinders, it with lock body support 1 in an end have the tooth bar 7 on the motion bar 5 of lock pin 6 to be meshed, whole lock can be installed in the car pipe of bicycle, for the volume that guarantees lock as far as possible little, be convenient to be installed in the car pipe, therefore, a section of motion bar 5 made flat one-tenth stairstepping, as Fig. 6, shown in Figure 7, tooth bar 7 is only opened on one section of the motion bar that is reamed.
When "T"-shaped key inserted 180 ° of "T"-shaped keyhole transfers, gear 8 drove tooth bars 7 and rotates, and the lock pin 6 of motion bar 5 one ends is inserted in the lockpin hole of bicycle front axle or axis and locks."T"-shaped key can be tooth punching on one side, and all tooth punchings of both sides that also can symmetry are all states of tooth punching of both sides among Fig. 1, and when "T"-shaped key was tooth punching on one side, the pellet shot from a slingshot on the lock core 3 had only one group.
For guaranteeing that the pinion 8 and the lock pin 6 of 7 pairs of motion bar 5 one ends of tooth bar have a predetermined pressure, contact with spring 10 at motion bar 5 other ends, and fix with plunger.
