The purpose is realized by the following technical scheme.
A high-strength anti-theft handle lock comprises a base component and a handle component, wherein a handle groove is formed in one side of a base of the base component, the handle component is arranged in the handle groove of the base, one end of a handle of the handle component is fastened and fixed in the handle groove of the base, the other end of the handle extends out of the bottom of the base through a rotating shaft, a sealing ring is arranged on the outer diameter of the rotating shaft in the base, and a torsion spring is arranged at the joint of the rotating shaft and the handle; the handle assembly is characterized in that a handle insert fixed on the handle is arranged at the bottom of the handle assembly, and the handle insert is a high-hardness steel plate. The handle insert is embedded into the bottom of the handle or the groove corresponding to the bottom of the handle, so that the strength and rigidity of the handle are enhanced, and the handle is prevented from being forcibly opened by cutting, prying and other destructive means.
The base assembly is characterized in that a base insert is arranged in a ring groove at the bottom edge of the base assembly and is a high-hardness steel plate. The base insert enhances the strength and rigidity of the base and prevents the base from being forcibly opened by means of damage such as prying.
The handle lock end of the handle assembly is provided with a lock core assembly, and the handle is fixed in the handle groove of the base through the lock core assembly. The above is an embodiment in which the handle is secured to the base by a plug assembly, which may also be secured to the base by a button or the like.
A raised arc-shaped step edge is arranged at one end, buckled with the handle, of the base assembly, and a bevel groove is formed in the bottom of the end, corresponding to the arc-shaped step edge, of the handle, buckled with the end. The structure prevents tools such as a screwdriver and the like from extending into the base to pry the handle.
The handle lock bilateral symmetry in base subassembly other end pivot hole is equipped with breach limit groove, is equipped with triangle protruding border between the breach limit groove, and the both sides in breach limit groove are equipped with triangle transition limit respectively, and handle subassembly's handle and pivot junction round pin axle bilateral symmetry are equipped with bellied triangle limit groove, and the triangle limit groove of handle is located the breach limit groove of base. The structure enables the rotation stroke of the handle to be limited, and further prevents tools such as a screwdriver and the like from extending into the base to pry the handle.
The utility model has reasonable structure design, convenient assembly and use, good anti-theft and anti-prying effects, and high overall rigidity and strength; it is suitable for being used as a rotary handle lock and the structural improvement of the similar products.
