[0028] Working principle:
[0029] During the actual design process of the present invention, the following defects existing in the prior art are solved: In the prior art, in order to realize leakage detection of the key of the anti-theft lock, the common practice is to take out the key and connect it to the leakage detection circuit, and then test the leakage part of the key; although this detection method simulates the leakage of the key, it cannot completely restore the effect of the key actually being used inside the anti-theft lock, and it cannot restore the real leakage situation. Therefore, the key leakage detection device of the prior art has certain defects. A universal adapter detector 2 is specifically proposed; the universal adapter detector 2 can be adapted to different models of keys 5, and can realize the detection effect of the key 5 under the actual working conditions. The universal adapter detector 2 includes a key 5 that is plugged into and installed inside the car anti-theft lock cylinder 1, and a shielding cover 6 is installed on the surface of the key 5. The shielding cover 6 can be sleeved on the surface of the key 5, thereby avoiding the phenomenon of electric shock caused by direct contact.
[0030] During the use of this detection device, the key 5 simulates the actual working conditions. That is, the key 5 is inserted into the interior of the lock cylinder 1 during the detection process; the chuck 3 and the bolt 4 are the fixing devices of the anti-theft lock. During the detection, the shielding cover 6 is placed on the surface of the key 5. The shielding cover 6 has a certain anti-electric shock effect. The reserved slot 7 set inside the shielding cover 6 can be adapted to install keys of different models and sizes. Conductive columns 9 are telescopically set on both sides of the shielding cover 6. The conductive columns 9 can achieve the effect of adjusting the detection position and depth on both sides of the shielding cover 6; the electrodes 8 at the ends of the conductive columns 9 are in direct contact with the surface of the key 5 to achieve the effect of contact detection. The spring 11 changes the internal extension length of the conductive column 9 under the action of the limit plate 10. The conductive columns 9 on both sides are connected to the wires 13 as the anode and cathode circuits respectively, and are finally connected to the surface of the ammeter 14, realizing current detection through the display screen 15, and then accurately measuring the location of the leakage.
