Description

Clamp type bike lock

The utility model relates to a kind of bicycle lock.

At present, for bicycle lock is to continue to use traditional sliding ring type structure.Though this lock is simple in structure, its safety is relatively poor.The snap close that the sealing that the car stealer often utilizes the iron wire hook to pass lock base and locking closure bottom is stirred lock is opened lock and bicycle is stolen.

The purpose of this utility model is to provide comparatively simple, the safe and reliable for bicycle lock of a kind of structure can not stolen because of lock is firm with the bicycle that guarantees people.

Technical conceive of the present utility model is: adopt the lock ring of two upper end band card wheels, when shutting under two lock rings termination close, when unblanking under two lock rings end separate; The card of one of them lock ring wheel is provided with bayonet socket so that realize two firm joints in lock ring lower end by this bayonet socket and the fastening of snap close, and the card wheel of another lock ring is provided with and connects lug that spring uses and realize two lock ring lower ends separation so that the elastic reaction by spring makes card take turns rotation.

Accompanying drawing is the structural representation of jaw type bicycle lock described in the utility model, below in conjunction with accompanying drawing the utility model is described in detail.

Referring to accompanying drawing, the utility model comprises right lock ring (1), lock base (2), locking closure (3), spring (7), is installed on the locking closure (3) and cylinder lock (10), T shape snap close (15) and left lock ring (21) band driving lever (12), it is characterized in that fixedly connected one of end has center hole and card wheel (5) band lug (8) on the right lock ring (1), fixedly connected one of end has center hole and card wheel (19) band bayonet socket (17) on the left lock ring (21); Lock base (2) is provided with the rotating shaft (4) that is complementary with the center hole that blocks wheel (5) and is provided with and blocks the rotating shaft (18) that the center hole of wheel (19) is complementary, described card wheel (5) is rotationally connected by its center hole and rotating shaft (4) formation, its lug (8) connects an end of spring (7), hook (6) the card wheel (19) that the other end of spring (7) connects lock base (2) is rotationally connected by its center hole and rotating shaft (18) formation, its bayonet socket (17) fastens with snap close (15), snap close (15) one ends are rotationally connected by its circular hole and rotating shaft (16) formation that is fixed on the lock base (2), its other end is fixedlyed connected with one of spring (14) end, and the other end of spring (14) is connected with the hook (13) of lock base (2).The gear teeth (20) engagement of the gear teeth (9) of described card wheel (5) and card wheel (19).Described lock base (2) and locking closure (3) tighten together or tighten together by welding method by some rivets after all the part assembling finishes.For ease of shutting, on left lock ring (21), be provided with handle (23), have one at end under the right lock ring (1) and supply the interface (24) that end inserts under the left lock ring (21).Can circular hole (11) be installed and square hole (22) is installed by it when using the utility model it is installed on the relevant position of bicycle.

Brief description action principle of the present utility model.When lock is under the unlocking condition, when shutting left lock ring (21) is pulled to the right, the card wheel (19) of fixedlying connected with left lock ring (21) just rotates counterclockwise, the card wheel (5) that is meshed with card wheel (19) then clockwise rotates and drives and is attached thereto the right lock ring (1) that connects and is moved to the left, so termination lumps together and makes lock be in the state of shutting under two lock rings.Meanwhile, spring (7) is in confined state, and snap close (15) is tightly fastening card wheel (19) plays the lock car to guarantee the firm joint of end under right lock ring (1) and the left lock ring (21) effect under the effect of spring (14).In the time of need opening lock, insert in the cylinder lock (10) the lock key and clockwise unlocking spring lock, the driving lever (12) that links to each other with cylinder lock (10) has upwards been dialled an end of snap close (15), and spring (14) makes snap close (15) separate with the bayonet socket (17) of card wheel (19) by compression.Because snap close (15) separates with bayonet socket (17) of blocking wheel (19), card wheel (5) rotates counterclockwise under the effect of above-mentioned compression spring (7) and drives right lock ring (1) and move right, the card wheel (19) that is meshed with card wheel (5) then clockwise rotates and drives left lock ring (21) and be moved to the left, the result that right lock ring (1) moves right with left lock ring (21) is moved to the left causes to hold under right lock ring (1) and the left lock ring (21) and separates, and at this moment lock is opened.

The utility model bicycle simple in structure, safe and reliable, suitable various uses.
