Description
Technical field the utility model relates to lockset and opens the key of lockset.
No matter the lockset that the present people of background technology use is hanging bright lock or be embedded in the interior built-in lock of door, and no matter whether it is called theftproof lock on paper, but basic goal all is as antitheft.The existing lockset keyhole of its lock core end in design all is outwardly open, and the robber adopts instrument such as screwdriver to insert easily lock is pried open, and makes the anti-theft feature of lock can not get ensureing.
The summary of the invention the purpose of this utility model will provide a kind of improved theftproof lock and key thereof exactly, and it can overcome existing lockset is effectively pried open by the people easily because of keyhole exposes, thereby influences the problem of anti-theft feature.
The purpose of this utility model is achieved in that theftproof lock has lock body, and lock core is installed in the lock body, is provided with keyhole in the lock core, it is characterized in that also being fixedly connected with backplate in the outer end of described lock core, is provided with on the backplate and leads to the arc road of keyhole.
As further scheme of the present utility model, be the side that the outlet in described arc road is arranged on backplate.
As the further scheme of another kind of the present utility model, be that being fixedly connected between described lock core and the backplate is welded construction.
The realization of the utility model purpose also depends on the key of opening theftproof lock, and this key has a handle and a spoon tooth, it is characterized in that also having intermediate zone between described handle and spoon tooth, and intermediate zone and a spoon tooth is chip architecture of the spring.
The utility model has been owing to adopted guard board structure in the lock core outer end, thus prevented directly to lockhole insert the instrument picking lock may, the anti-theft feature of theftproof lock is strengthened; Simultaneously, the utility model has been also owing to adopted chip architecture of the spring with the main body of key, thus make key by the arc road insert, extracting keyhole still can be freely smooth and easy; And also because lock core and backplate have been formed the structure that connects firmly together, when key was inserted into the position in lock after, driving lock core by the rotation backplate can open lock or locking the utility model easily.
Description of drawings Fig. 1 is the structural representation of the utility model theftproof lock, and Fig. 2 is the structural representation that the utility model is opened the key of theftproof lock, and the utility model is described in further detail below in conjunction with accompanying drawing.
Specific embodiment Fig. 1 shows the structure of the utility model theftproof lock, and lock core 4 is installed in the lock body 1, is provided with keyhole 5 in the lock core 4, and the outer end of lock core 4 also is fixedly connected with backplate 3, is provided with on the backplate 3 and leads to the arc road 2 of keyhole 5.As a kind of preferred version, the outlet in described arc road 2 is arranged on the side of backplate 3, being fixedly connected between described lock core 4 and the backplate 3 is welded construction.
Fig. 2 shows the structure that the utility model is opened the key of theftproof lock, and this key has handle 6 and spoon tooth 8, also has intermediate zone 7 between handle 6 and the spoon tooth 8, and intermediate zone 7 is a chip architecture of the spring with spoon tooth 8.As a kind of preferred version, the chip architecture of the spring that key of the present utility model adopts spring steel to make, a spoon tooth 8 both can have been made and one-sidedly also can make bilateral.
The course of work of the present utility model is: the key of chip architecture of the spring is inserted keyhole 5 by the arc road on the backplate 32, make lock pin be pushed up lock core 4 rotating positions, the intermediate zone 7 of key rests on 2 positions, arc road and coincide with this position shape, rotates backplate 3 with hand and drives lock core 4 with theftproof lock unlatching or locking; Extract key, lock pin resets, and lock core 4 is locked, and this moment, backplate 3 can not rotate in any case to backplate 3 application of forces, and theftproof lock remains on the stable state of unlatching or locking.
