The lock sheath or the shaft sheath are provided with the shaft connecting holes, and a matching card stopping part which can limit the lockpin rotation is provided in the shaft connecting hole and the shaft connecting end of the lockpin or the pin body. The utility model has good anti-theft performance, simple structure, and low manufacturing costs.
Description
Technical field
The utility model relates to a kind of theftproof lock, particularly a kind of multiduty U type theftproof lock.
Background technology
Existing U type theftproof lock generally comprises U-shape lock frame, lock tube, axle sleeve and lock pin, and lock tube and axle sleeve are fixed on the two ends of U-shape lock frame, and the lock pin pivot bush unit forms a fixed structure in lock tube and axle sleeve.Lock pin comprises main shaft, be coupling in the lock end of lock tube and be coupling in the tail end of axle sleeve.As the patent No. is the Chinese utility model patent of ZL 012210056.Though existing U type theftproof lock has pick-proof, the anti-function of sawing, preventing welding, because its lock end is designed to cylindrical shape, after artificial A/F with the U-shape lock frame compressed, tail end just broke away from axle sleeve.As long as firmly rotating lock pin just can unblank easily, the chance of theft is provided for people like this with illegal objective.Simultaneously, the lock tube and the cylinder-type lock end of existing theftproof lock are destroyed easily, cause the consequence that can't lock or unblank.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of safety firm, is not easy to be pried open, specious, a kind of novel anti-burglar lock that cost of production is low.
A kind of novel anti-burglar lock of the present utility model, comprise U-shape lock frame, lock pin and be located at the lock tube and the axle sleeve at U-shape lock frame two ends, be provided with the lock core that can spin with lock pin in the lock tube, lock pin comprises pivoted connection end and the pin body that is coupling in lock tube and axle sleeve, described lock tube or axle sleeve are provided with shaft-jointed hole, and shaft-jointed hole and lock pin pivoted connection end or pin body are provided with that coupling is used, as can to limit lock pin rotation fastener.
Described fastener is recess or a protuberance of being located at the mutual coupling on be coupling hole wall and lock pin surface.
The recess of described shaft-jointed hole is the polygonal interior angle in shaft-jointed hole cross section, and the protuberance of described lock pin is the polygonal summit of lock pin cross section and shaft-jointed hole coupling.
Described shaft-jointed hole is provided with arc-shaped depression portion, and described lock pin is provided with the arc protuberance with the shaft-jointed hole coupling.
Described shaft-jointed hole is provided with the arc protuberance, and described lock pin is provided with the arc-shaped depression portion with the shaft-jointed hole coupling.
Described lock pin and lock core spin the end screw thread be internal thread or external screw thread.
Described lock pin comprises and is coupling in the lock end of lock tube and is coupling in the tail end of axle sleeve, is provided with a screens in the described axle sleeve, and the tail end correspondence is provided with a convex bayonet lock.
The shaft-jointed hole of theftproof lock lock tube of the present utility model can limit the rotation of lock pin, even dwindle the width of U-shape lock frame opening, also can not unblank because of rotating lock pin; Therefore can't open theftproof lock by the A/F that draws back or dwindle the U-shape lock frame, can only just can unblank with the key of special use.So the utility model theftproof performance is good, simple in structure, cheap for manufacturing cost.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model lock end;
Fig. 3 is the structural representation of the utility model tail end.
The specific embodiment
As shown in Figure 1, the utility model comprises U-shape lock frame 1, lock pin 2 and is located at the lock tube 3 and the axle sleeve 4 at U-shape lock frame two ends, is provided with the lock core 5 that can spin with lock pin 2 in the lock tube 3.Lock pin 2 comprises lock end 21, tail end 22 and pin body, and lock end 21 is coupling in lock tube, and lock end 21 can be designed to internal thread or external thread structure with lock core 5 screw-on places, and tail end 22 is coupling in axle head.Be provided with a screens 41 in the axle sleeve, tail end 22 correspondences are provided with a convex bayonet lock 23.Lock tube 3 or axle sleeve 4 are provided with the shaft-jointed hole of the fastener that can limit the lock pin rotation, and the distance of the Kong Bianyu axle of shaft-jointed hole is inconsistent, and promptly the cross section of shaft-jointed hole is non-circular, the fastener coupling use of lock end 21, tail end 22 or pin body and shaft-jointed hole.The cross section of shaft-jointed hole can be quadrangle, hexagon, Any shape trapezoidal, oval or that be made of plural arc section, and the shaft-jointed hole of present embodiment adopts hexagonal structure.
Shown in Fig. 2,3, the fastener of shaft-jointed hole is recess or a protuberance of being located at the mutual coupling on be coupling hole wall and lock pin surface.The recess of shaft-jointed hole is the polygonal interior angle in shaft-jointed hole cross section, and the protuberance of lock pin is the polygonal summit of lock pin cross section and shaft-jointed hole coupling.In the present embodiment, the recess of shaft-jointed hole is hexagonal interior angle.When the shaft-jointed hole of lock tube 3 was hexagonal structure, the cross section of lock end 21 also was a hexagon, just can't rotate after lock end 21 inserts shaft-jointed hole like this.When axle sleeve 4 was hexagon, the cross section of pin body and tail end 22 must be a hexagon also, made lock pin 2 to rotate and can not open theftproof lock.Shaft-jointed hole also can be made as arc-shaped depression portion or protuberance, and the lock pin correspondence is made as arc protuberance or the recess with the shaft-jointed hole coupling.Lock end 21 and tail end 22 can insert, withdraw from shaft-jointed hole easily like this, but can't rotate in shaft-jointed hole; Even if therefore compression U-shape lock frame 1 also can't be opened theftproof lock of the present utility model by rotation lock pin 2.
When locking, the lock end 21 with lock pin 2 inserts shaft-jointed hole earlier, and key screws tight lock core 5 and lock end 21, just finishes the action of locking.When unblanking,, lock pin 2 is just unblanked easily to pusher by the key lock core 5 of outwarding winding.
