Description
The utility model is a kind of security door safety lock body of new structure, and it relates to improvement on existing product structure and the performance and raising.
The theftproof lock of the security door in using at present is divided into that outer tapered end separates with lock body or these two kinds of forms of entire combination, but the lockhole panel on their lock body is exposed all, referring to shown in Figure 1, like this, the crime molecule will root easily destroys outer tapered end or with the instrument of special use outer tapered end is pulled out.Bring hidden danger to safety.
The purpose of this utility model designs the outer tapered end built-in lock body that a kind of new structure is provided at existing deficiency on the present product structure just, and its molecule that can successfully prevent to commit a crime destroys outer tapered end.
The purpose of this utility model realizes by following measure:
The outer tapered end built-in lock of this kind body, its internal construction and present employed theftproof lock be difference not, it comprises lock body and these primary clusterings of lockhole panel equally, be characterised in that on its structure design, one stiffener is installed on the outer perimeter of lockhole panel, and the diameter of the circular hole at this stiffener center only is slightly larger than the diameter of the keyhole on the lockhole panel.The molecule that so just can successfully prevent to commit a crime destroys outer tapered end.According to changing on this structure, the assembly direction of the lock of this kind band stiffener is for from inside to outside.
The drawing of accompanying drawing is described as follows:
Fig. 1 is the structure and the assembly relation schematic diagram of existing lock body product
Fig. 2 is the structure and the assembly relation schematic diagram of the utility model product
Below with reference to drawings and Examples the utility model is described in further detail:
Shown in accompanying drawing 2, the outer tapered end built-in lock of this kind body comprises assemblies such as lock body 1 and lockhole panel 2, it is characterized in that, one stiffener 3 is installed on the outer perimeter of lockhole panel 2, and the diameter of its center hole 4 only is slightly larger than the diameter of the keyhole on the lockhole panel 2.Stiffener 3 adopts high-intensity hard metal to make.In addition, the assembly direction of the lock body of this kind band stiffener 3 is for from inside to outside.
The utility model product is compared with existing product to have simple in structurely, and safety firmly, and is easy to process etc. Advantage.
