Detailed Description

In order to illustrate the invention more clearly, the invention is further described below with reference to preferred embodiments. It is to be understood by persons skilled in the art that the following detailed description is illustrative and not restrictive, and is not to be taken as limiting the scope of the invention.

As shown in figure 1, a semi-automatic latch lock box is characterized by comprising a box body 1, wherein an upper hook 2 is arranged at the upper part of the box body, a lower hook 3 is arranged at the lower part of the box body, one end of each of the upper hook 2 and the lower hook 3 is positioned inside the box body 1, the other end with a bent hook extends out of the box body 1, a first transmission device 4, a second transmission device 5 and a third transmission device 6 are arranged in the box body 1, the first transmission device 4 drives the second transmission device 5 to displace, the second transmission device 5 drives the upper hook 2 to displace downwards, the third transmission device 6 drives the lower hook 3 to displace upwards through the displacement of the upper hook 2, one end of the second transmission device 5 is riveted with one end of the first transmission device 4, the other end of the second transmission device 5 is riveted with the upper hook 2, one end of the third transmission device 6 is riveted with the upper hook 2, the other end of the third transmission device 6 is riveted with the lower hook 3. One end in the box body of the upper hook 2 is provided with a first safety device 7 and a second safety device 8, and the first safety device 7 is used for locking the upper hook 2. Go up couple 2, couple 3, second safeties 8 down and all adopt the spring return, first safeties 7 adopt the torsional spring return. The box body is made of stainless steel, and the first transmission device, the second transmission device and the third transmission device are made of galvanized plates.
