Abstract
The utility model relates to a high theftproof U type lock, including U type locking lever and lock body, the lock body includes tapered end subassembly, stop and lock body shell, tapered end subassembly and stop setting in the lock body shell, U type locking lever both ends are the mortise lock end, with mortise lock end clearance fit jack on the lock body shell, with arbitrary center that is in the cross -section of U type locking lever, the last part at least of section contour extremely distance and all the other parts at center are extremely the center apart from the imbalance, the jack shape is the same with the section contour shape of U type locking lever. Since U type locking lever cross -section and jack be not be circular, ought the one end of U type locking lever is stolen the molecule sawing and is destroyed the back, U type locking lever still can't wind other end rotation and open the lock, must increase the degree of difficulty of unblanking simultaneously with opening the lock behind the equal sawing in both ends, has improved theftproof nature.
Description
Technical field
The utility model relates to field of lockset, and more particularly, it relates to a kind of high Anti-theft U-shape lock.
Background technology
U-shaped a kind of common lockset, is usually used on the bicycle such as bicycle, electric motor car with two wheels as lock.U-shape lock generally includes U-shape lock bar and lock body, described lock body comprises lock head component, stop and lock body shell, lock head component and stop are arranged in lock body shell, described U-shape lock bar one end is link, the other end is mortise lock end, also the U-shape lock bar two ends of part U-shape lock are had to be mortise lock end, described lock body shell is provided with the connecting hole and mortise lock hole that coordinate with link and mortise lock splaying respectively, described link inserts in connecting hole and is connected with lock body, described mortise lock end can insert with mortise lock hole and extract and coordinate, lock head component controls stop position, locking or unblock are carried out to the mortise lock end inserted in mortise lock hole.Because the locking bar cross section of existing U-shape lock and the shape in connecting hole and mortise lock hole are circular, therefore, only need by sawed-off for one end of locking bar, U-shape lock bar can be rotated around the other end and opened by lock, theftproof performance is still weak.
Summary of the invention
The purpose of this utility model is the deficiency existed for overcoming prior art, and provides the U-shape lock that a kind of theftproof performance is stronger.
For achieving the above object, the utility model provides following technical scheme: a kind of high Anti-theft U-shape lock, comprise U-shape lock bar and lock body, described lock body comprises lock head component, stop and lock body shell, lock head component and stop are arranged in lock body shell, described U-shape lock bar two ends are mortise lock end, described lock body shell is provided with the mortise lock hole coordinated with mortise lock splaying, described mortise lock end can insert with mortise lock hole and extract and coordinate, it is characterized in that: centered by any point in the cross section of described U-shape lock bar, distance at least partly to distance and the remainder extremely described center at described center on described cross section profile is unequal, described mortise lock hole shape is identical with the cross-section profile shape of U-shape lock bar.
The utility model is by by unequal for the distance at least partly to distance and the remainder extremely described center at described center on described cross section profile, namely U-shape lock bar cross section and mortise lock hole shape are not rounded, after the sawed-off destruction of molecule is stolen in one end of described U-shape lock bar, described U-shape lock bar still cannot rotate around the other end and be opened by lock, must simultaneously two ends are all sawed-off after lock could be opened, add the difficulty of unblanking, improve theftproof.
Below in conjunction with specific embodiments and the drawings, the utility model is described further.
