Detailed Description

The technical features and advantages of the present invention are described in more detail with reference to the accompanying drawings.

In the first embodiment, taking the example of the mechanical lock of the present invention being installed on a box, the mechanical lock comprises a box, the box comprises a bottom plate, two side plates, two end plates and a cover plate, one of the end plates is used as the fixed part 2 of the present invention, the cover plate 1 is used as the movable part of the present invention, the opposite surfaces of the two side plates are both provided with a groove, the two sides of the movable part 1 are respectively arranged in the grooves, the two sides of the movable part 1 can slide in the grooves, the fixed part 2 is provided with a locking device, the locking device is provided with a tenon 5, the movable part 1 is provided with a mortise 4, the tenon 5 is provided with a handle 18, the tenon 5 can be withdrawn from the mortise 4 of the movable part 1 by rotating and moving the handle 18, and the locking device further comprises: a cross bar 6 fixed with the tenon 5, a left support bar 10, a right support bar 9 respectively connected with the fixed part 2 by a shaft, a groove 7 arranged on the fixed part 2, a chute 8 arranged in the groove 7, the tenon 5 arranged in the chute 8, the left support bar 10 connected with the left side of the groove 7 by a left shaft 12, the right support bar 9 connected with the right side of the groove 7 by a right shaft 11, a left spring 14 arranged between the left side of the groove 7 and the left support bar 10, a right spring 13 arranged between the right side of the groove 7 and the right support bar 9, a lower spring 15 arranged between the lower side of the chute 8 and the tenon 5, notches respectively arranged at the two ends of the cross bar 6, the notches respectively matched with the end parts of the left support bar 10 and the right support bar 9, a handle 18 connected with the tenon 5 by a central shaft 16, the central shaft 16 passing through the fixed part 2 and the shaft body of the tenon 5 and provided with a cross pin 3, the fixed part 2 is provided with a long hole which can enable the central shaft to transversely or vertically move at the penetrating position of the central shaft 16, the fixed part 2 is provided with a cover plate which can hide the locking device, when the movable part 1 is opened, the handle 18 is rotated, the hand exerts force downwards, when the horizontal pin 3 on the central shaft 16 rotates to the nine o 'clock direction, the horizontal pin 3 pushes the left support rod 10 to compress the left spring 14, the tenon 5 and the cross rod 6 can slightly move downwards, the end part of the left support rod 10 slightly enters the notch of the cross rod 6, the handle 18 is continuously rotated, when the horizontal pin 3 on the central shaft 16 rotates to the three o' clock direction, the horizontal pin 3 pushes the right support rod 9 to compress the right spring 13, the tenon 5 and the cross rod 6 can both move downwards, the tenon 5 exits the mortise 4, the movable part 1 can be opened, but the precondition is that when the handle 18 is rotated, the hand must exert force downwards, if the hand is loosened halfway hand, the downward force is not, the lower spring lock 5 can bounce the tenon 5 together with the cross rod 6, so that the left support rod 10 and the right support rod 9 are restored under the elastic forces of the left spring 14 and the right spring 13, the left support rod 10 and the right support rod 9 are simultaneously propped against the lower part of the cross rod 6, the tenon 5 cannot be withdrawn from the mortise 4 below the cross rod 6, and the machine-closing lock cannot be opened.
