Detailed Description

To further illustrate the technical means and effects of the present invention adopted to achieve the intended purpose, the following detailed description of the embodiments of the present invention is provided in conjunction with the accompanying drawings and preferred embodiments.

Referring to fig. 1 to 3, an embodiment of the present invention provides a dual-safety logistics lock, including a lock body 1, wherein the lock body 1 has a fixed end 11 and a movable end 12. The logistics lock of the embodiment further comprises a protective sleeve 2 connected between the fixed end 11 and the movable end 12. Simultaneously, be provided with a detection wire 3 in this protective case 2, both ends contact (31, 32) that should detect wire 3 all are located stiff end 11 to the electricity is connected to the control circuit board of lock body 1, both ends contact (31, 32) through detecting wire 3 all set up in stiff end 11, and do not have the contact in the expansion end 12, even plug expansion end 12 repeatedly, both ends contact (31, 32) that detect wire 3 also can not receive wearing and tearing damage, bad contact's phenomenon can not appear.

Meanwhile, a resistor 4 is arranged on the detection lead 3, and the resistor 4 is positioned in the movable end 12. Preferably, the resistor 4 is disposed at the center of the entire length of the detection wire 3, i.e., at the end of the movable end of the detection wire 3. Specifically, as shown in fig. 3, two ends of the detection wire 3 are folded in half to form a first end portion 33 located in the fixed end 11 and a second end portion 34 located in the movable end 12, two end contacts (31, 32) of the detection wire 3 are located on the first end portion 33, and the resistor 4 is located on the second end portion 34. This embodiment is through setting up resistance 4 on detecting wire 3 to set up resistance 4 in movable end 12, through the resistance of real-time detection resistance 4, as long as the resistance value changes, the system is reported to the police promptly, from this, improves the security by a wide margin.

Normally, the resistance of the resistor 4 detected by the system is kept constant or within a certain range, and only when the detection wire 3 is damaged, the resistance of the resistor 4 detected by the system is changed greatly. For example, when the detection wire 3 is cut off at any position by a person and then connected with an external wire, the detection wire 3 cannot form a loop, and the detected resistance value is greatly changed, so that the detection wire 3 is judged to be damaged, and the system gives an alarm.

In this embodiment, preferential, this protective case 2 is the mild steel pipe, and this embodiment will detect wire 3 and set up in protective case 2 (mild steel pipe), is protected detection wire 3 by protective case 2 (mild steel pipe), can not receive external environment to disturb, can not harm inner circuit, effectively prevents to appear the electric leakage phenomenon that discharges, uses not impaired for a long time moreover, improves life.

As a further improvement of this embodiment, as shown in fig. 4, a locking piece 5 is connected to an end portion of the protective sleeve 2 near the movable end 12, a magnet is disposed on a lower end surface of the locking piece 5, and a hall sensor 6 corresponding to the magnet is disposed inside the lock body 1 and at the movable end 12. When the locking block 5 is inserted into the lock body 1, the position of the magnet on the lower end face of the locking block 5 is changed, so that the distance between the Hall sensor 6 and the magnet is changed, and therefore, the Hall sensor 6 is used for detecting whether the locking block 5 is inserted in place or not and informing the system of the insertion.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the technical scope of the present invention, so that other structures obtained by adopting the same or similar technical features as the above embodiments of the present invention are all within the protection scope of the present invention.
