The design is connected with the safety component 7 through the hook rod 13, so that the safety of locking of the lock catch can be further improved, and the upper and lower retaining rings can fall off when the bolt 6 is prevented from loosening, so that potential safety hazards are caused.

As shown in fig. 6, fig. 6 is a schematic sectional view of the area C in fig. 5. The safety assembly 7 comprises a telescopic rod 71 and a second spring 72; the telescopic rod 71 is positioned at the second through hole 24 communicated with the hook groove 23, one end of the telescopic rod 71 is positioned outside the second horizontal plate 21, and the other end of the telescopic rod 71 is provided with a second hook 74 for being clamped with the hook rod 13; the second through hole 24 is provided with a second chute 25, the middle part of the telescopic rod 71 is provided with a middle plate 73 positioned in the second chute 25, and the second spring 72 is positioned between the middle plate 73 and the second chute 25. In the above design, the second hook 74 can be released from the hook lever 13 by pressing the telescopic lever 71, so that the up-down buckle can be opened.

The hook 131 below the hook lever 13 is provided with a second inclined surface 1311 abutting against the second hook 74 in the direction in which the hook lever 13 is inserted. When the hook 131 is inserted into the hook groove 23, the second hook 74 abuts against the second inclined surface 1311, so as to generate a component force in the horizontal direction, thereby pushing the second hook 74 to move outwards, and when the second hook 74 is completely higher than the hook 131, the elastic force of the second spring 72 pushes the second hook 74 to be clamped with the hook 131.

The specific theory of operation, when needing to use sliding latch device to lock the part that waits to lock, will go up buckle 1 and lower buckle 2 cover and put and wait to lock the part outside, will slide downwards with the movable pin 4 that upper bracket 31 is connected to make the limiting plate 42 joint of movable pin 4 to hook 511, accomplish the combination connection of axle bed 3, merge the horizontal plate of opposite side hasp simultaneously, with the hooked rod 13 joint of first horizontal plate 11 to the second hook 74 of second horizontal plate 21, accomplish the preliminary lock joint of horizontal plate, screw in screw hole 22 through bolt 6 and with the horizontal plate complete fastening connection.

When the components in the locking device are required to be taken out, the bolt 6 is partially unscrewed from the threaded hole 22, the telescopic rod 71 is pressed simultaneously, so that the second hook 74 is separated from the clamping hook 131 of the hook rod 13, the first horizontal plate 11 and the second horizontal plate 21 are separated, the clamping rod 51 in the lower support 32 is pushed simultaneously, the hook 511 on the clamping rod 51 is separated from the limiting plate 42 of the movable pin 4, the movable pin 4 is enabled to slide upwards out of the sliding groove 321, the upper support and the lower support are enabled to be separated in a limited mode, the limiting plate 42 can prevent the movable pin 4 from being completely separated from the lower support 32, limited separation of the upper retaining ring and the lower retaining ring is achieved, the middle component can be taken out without completely opening the lock catch, the unlocking step is simplified, and the construction efficiency is improved.

The foregoing description is only illustrative of the present utility model and is not intended to limit the scope of the utility model, and all equivalent structures or equivalent processes or direct or indirect application in other related technical fields are included in the scope of the present utility model.
