Abstract

The utility model relates to a new theft-proof bicycle lock comprising a lock pipe, a lock column, a lock body sleeve, a lock bolt and a spring. As the utility model adopts the structure that the lock column can comprise a main lock column, a minor lock column and a small lock column, and each cross-sectional area of the main lock column and the minor lock column is equal or approximate to the cross-sectional area of an inner hole of the lock pipe, or the main lock column, the minor lock column and the lock pipe form clearance fit, each cross-sectional area of the main lock column and the minor lock column is furthest increased under the condition that the dimension of the lock pipe is definite, and accordingly, favorable theft-proof performance of the utility model is effectively ensured. In addition, the utility model also adopts the structure that a plurality of hollow lock column sleeves are arranged between the lock pipe and the small lock column, and accordingly, the small lock column can be ensured to stably slide in the lock pipe; in addition, the theft-proof performance of the lock becomes better. The utility model has the advantage of reasonable structure, artful design, good performance, convenience and practicability.

Description

A kind of novel anti-theft bicycle lock

The utility model is a kind of bicycle lock, belongs to the renovation technique of bicycle lock.

Existing bicycle lock, in order to realize the locking of locking bolt and lock, it is exactly to have to leave certain spacing between lock and the lock pipe that there is a common problem in its structure, under the certain situation of lock pipe size, the sectional area of lock can only be made littler than the sectional area of lock pipe orifice, and therefore, the robber usually can cut off lock easily, bicycle is stolen, and the anti-theft capability of lockset is relatively poor.

The purpose of this utility model is to overcome above-mentioned shortcoming and provides a kind of and can guarantee the anti-theft bicycle lock that its theftproof performance is good effectively.

Structural representation of the present utility model as shown in Figure 1, include lock pipe (1), lock (2), lock body sheath (3), locking bolt (4), spring (6), lock (2) is provided with locking bolt (4) and matches to realize the draw-in groove (21) of locking, it places in the lock pipe (1), spring (6) is nested with on lock (2), and an end of spring (6) is installed on the lock (2), other end fastening is on lock pipe (1), wherein lock (2) can include main lock (2A), secondary lock (2B), little lock (2C), the sectional area of main lock (2A) and secondary lock (2B) is greater than the sectional area of little lock (2C), and main lock (2A) and secondary lock (2B) are packed in the two ends of little lock (2C) respectively.

The cross sectional shape of above-mentioned main lock (2A), secondary lock (2B) and little lock (2C) can be circle, also can be rectangle.

The sectional area of above-mentioned main lock (2A) and secondary lock (2B) equates to be matched in clearance between close or main lock (2A) and secondary lock (2B) and the lock pipe (1) with the sectional area of lock pipe (1) endoporus.

Describe concrete structure of the present utility model in detail below in conjunction with embodiment:

Embodiment 1:

Structural representation of the present utility model as shown in Figure 1, include lock pipe (1), lock (2), lock body sheath (3), locking bolt (4), spring (6), lock (2) is provided with locking bolt (4) and matches to realize the draw-in groove (21) of locking, it places in the lock pipe (1), spring (6) is nested with on lock (2), and an end of spring (6) is installed on the lock (2), other end fastening is on lock pipe (1), wherein lock (2) can include main lock (2A), secondary lock (2B), little lock (2C), the sectional area of main lock (2A) and secondary lock (2B) is greater than the sectional area of little lock (2C), and main lock (2A) and secondary lock (2B) are packed in the two ends of little lock (2C) respectively.The cross sectional shape of above-mentioned main lock (2A), secondary lock (2B) and little lock (2C) can be circle, also can be rectangle.Easy to process for making, the cross sectional shape of main lock (2A), secondary lock (2B) and little lock (2C) is as circle in the present embodiment.The sectional area of above-mentioned main lock (2A) and secondary lock (2B) equates to be matched in clearance between close or main lock (2A) and secondary lock (2B) and the lock pipe (1) with the sectional area of lock pipe (1) endoporus, is matched in clearance between main lock (2A) and secondary lock (2B) and the lock pipe (1) in the present embodiment.

Lock car for the convenience of the user, also be connected with handle (7) on the above-mentioned secondary lock (2B).For avoiding little lock (2C) situation of Free Slosh in lock pipe (1), to occur effectively, to guarantee the smooth sliding of little lock (2C) in lock pipe (1), and make the theftproof performance of lockset better, also be provided with the lock cover (5) of several hollows between above-mentioned lock pipe (1) and the little lock (2C), little lock (2C) is located on the lock cover (5).For making structure of the present utility model simple as far as possible, can guarantee its functional performance again, be provided with a lock cover (5) in the present embodiment.In addition, above-mentioned lock cover (5) can be packed in lock pipe (1), and an end of spring (6) is installed on the end of secondary lock (2B), and other end fastening is on lock cover (5).

When the utility model uses, it is installed on the bicycle, the user spurs handle (7) and drives secondary lock (2B) toward counterclockwise sliding (as shown in Figure 1), the C end of main lock (2A) is inserted in the D end of lock pipe (1), when the draw-in groove (21) on the little lock (2C) is corresponding with the position of locking bolt (4), then realize the locking of locking bolt and lock, compress spring (6) simultaneously.When need are unblanked, then turn key, make locking bolt (4) leave draw-in groove (21), at this moment, little lock (2C) and be attached thereto main lock (2A) together, secondary lock (2B) resets under the effect of spring (6).

The utility model is because the employing lock can include the structure of main lock, secondary lock, little lock, and the sectional area of main lock and secondary lock equates with the sectional area of lock pipe orifice to be matched in clearance between close or main lock and secondary lock and the lock pipe.Therefore, under the certain situation of lock pipe size, improved the sectional area of main lock and secondary lock to greatest extent, thereby guaranteed that effectively its theftproof performance is good; In addition, the utility model has also adopted between lock Guan Yuxiao lock and has been provided with the structure of several hollow lock covers, thus can guarantee the smooth sliding of little lock in the lock pipe, and make the theftproof performance of lockset better.The utility model is a kind of rational in infrastructure, design ingenious, function admirable, convenient and practical novel anti-theft bicycle lock.
