Abstract
The utility model discloses an anti-theft lock with improved structure, which comprises a U-shaped lock frame and a straight rod lock bolt. A hinged end of the U-shaped lock frame is rotatably connected with one end of the straight rod lock bolt, a free end of the U-shaped lock frame is connected with an opening-closing lock tenon at an opposite end of the straight rod lock bolt, a lock cylinder is disposed inside the straight rod lock bolt, a lock hole of the lock cylinder is disposed on the side of a rotary connection end of the straight rod lock bolt, and a through hole disposed at the hinged end of the U-shaped lock frame is correspondingly engaged with the lock hole of the lock cylinder when the anti-theft lock is in locking state. Compared with the prior art, the anti-theft lock has the advantages of 1 simple structure, convenient manufacturing and realization of being formed by means of structural improvement on the basis of an existing U-shaped anti-theft lock, 2 novel structure, safe and reliable properties, comparatively excellent anti-theft performance and capability of effectively preventing burglary members from employing special tools to unlock the anti-theft lock to steal, 3 low cost and capability of being favorable for market competition.
Description
Technical field
The utility model relates to a kind of theftproof lock, belongs to wheel anti-theft product technical field such as motorcycle, bicycle, refers in particular to a kind of theftproof lock that improves structure.
Background technology
Vehicle such as motorcycle, electric motor car is the important vehicles of current people's trip, and particularly in small and medium-sized cities and cities and towns, its scope of application is more extensive.And how to prevent that own loved vehicles are stolen, then be the problem that car owners very are concerned about.At the stolen problem of vehicle, one of solution is theftproof lock on the vehicle, so occurred a large amount of fashionable, anti-theft lock for vehicle that structure is different on the market, U type theftproof lock is wherein a kind of.
U type theftproof lock generally comprises U-shape lock frame and straight-bar locking bolt, one end of the hinged end of U-shape lock frame and straight-bar locking bolt is rotationally connected, free end opens and closes with the opposite end of straight-bar locking bolt and is connected, and straight-bar locking bolt inside is provided with lock core and lock core lockhole in straight-bar locking bolt and the free-ended link position of U-shape lock frame, and to be positioned at this link position distolateral, during use, private key inserts the lock core rotation and unblanks, the U-shape lock frame is passed behind the wheel hole to live with straight-bar locking bolt snap close, extract private key, thereby make the wheel can't normal rotation, easy to use, and have certain anti-theft feature.But, thief is easy to utilize special tool to insert in the lock core lockhole, twisting destroys lock core by force, reach the purpose of opening theftproof lock, simultaneously, the lock core lockhole of this U type theftproof lock is exposed to the outside, makes that thief can be than being easier to carry out picking lock, cause the safety factor of this theftproof lock not high enough, thereby cause vehicle stolen easily.
The utility model content
The purpose of this utility model is to overcome shortcoming of the prior art with not enough, and a kind of theftproof lock of simple in structure, safe and reliable, improvement structure that anti-theft effect is preferable is provided.
To achieve these goals, the utility model is realized by following technical scheme:
A kind of theftproof lock that improves structure comprises U-shape lock frame and straight-bar locking bolt, and an end of the hinged end of described U-shape lock frame and straight-bar locking bolt is rotationally connected, and free end opens and closes trip with the opposite end of straight-bar locking bolt and is connected, and straight-bar locking bolt inside is provided with lock core; It is distolateral that the lockhole of described lock core is located at being rotationally connected of straight-bar locking bolt, and the U-shape lock frame is provided with one when theftproof lock is in blocking and the through hole of lock core lockhole corresponding matching in its hinged end.
Further, the supporting private key that is provided with of described lock core, the spoon bar of private key is provided with a smooth cylinder at the link with the shank of the key, and smooth cylindrical length adapts to the through hole of U-shape lock frame and cooperates.
Further, the through hole of described U-shape lock frame is provided with a pair of reseting spring leaf that is used to cover through hole in nose end position toward the outer side.
The utility model compared with prior art, its beneficial effect is:
1, simple in structure, simple for production, on the architecture basics of existing U type theftproof lock, improve forming;
2, novel structure, safe and reliable, theftproof performance is preferable, and the molecule that effectively avoids theft utilizes special tool to open theftproof lock and steals;
3, cost is low, helps market competition.
In order to understand the utility model more clearly, set forth the specific embodiment of the present utility model below with reference to description of drawings.
Description of drawings
Fig. 1 is the structural representation of the utility model blocking.
Fig. 2 is the partial sectional view of Fig. 1.
Fig. 3 is the structural representation of the utility model unlocking condition.
Fig. 4 is the partial sectional view of Fig. 3.
The specific embodiment
Shown in Fig. 1～4, the theftproof lock of improvement structure described in the utility model comprises U-shape lock frame 1 and straight-bar locking bolt 2, and the hinged end 11 of described U-shape lock frame 1 is rotationally connected with an end of straight-bar locking bolt 2, and free end 12 opens and closes trip with the opposite end of straight-bar locking bolt 2 and is connected.
Above-mentioned straight-bar locking bolt 2 inside are provided with lock core, and it is distolateral that the lockhole 21 of lock core is located at being rotationally connected of straight-bar locking bolt 2; And U-shape lock frame 1 is provided with one when theftproof lock is in blocking and the through hole 13 of lock core lockhole 21 corresponding matching in its hinged end 11, and through hole 13 is provided with a pair of reseting spring leaf 131 that is used to cover through hole 13 in nose end position toward the outer side.
The supporting private key 3 that is provided with of above-mentioned lock core, the spoon bar 32 of private key is provided with a smooth cylinder 33 at the link with the shank of the key 31, and the length of smooth cylinder 33 adapts to the through hole 13 of U-shape lock frame 1 and cooperates.
Use principle of the present utility model is as described below: during use, private key inserts the through hole of U-shape lock frame, reseting spring leaf is stressed to be strutted, the spoon bar of private key passes the lock core lockhole that through hole enters the straight-bar locking bolt, rotate private key and drive the lock core rotation, remove the straight-bar locking bolt and be connected, extract private key afterwards and can rotate the straight-bar locking bolt around pin joint and open theftproof lock with the free-ended trip of U-shape lock frame; If do not extract private key, because private key passes across U-shape lock frame through hole and straight-bar locking bolt lock core,, the straight-bar locking bolt is connected even removing trip with U-shape lock frame free end, the straight-bar locking bolt promptly can't be unblanked because the inhibition of private key still can't rotate; Simultaneously since built-in lock pin in the straight-bar locking bolt and lockhole blocked by the U-shape lock frame, disguised better, the difficulty of thief picking lock is bigger, thereby has improved theftproof performance, and is safer reliable.
The utility model is not limited to above-mentioned embodiment, if various changes of the present utility model or modification are not broken away from spirit and scope of the present utility model, if these are changed and modification belongs within claim of the present utility model and the equivalent technologies scope, then the utility model also is intended to comprise these changes and modification.
