Specifically, the second slider 130 may slide back and forth along the direction of the second groove 114, and when the lock head 131 extends, it may be locked in the locking notch 1031 on the chassis body 103, so as to control the chassis cover 102 not to move in a direction perpendicular to the plane of the chassis cover 102 and in a direction parallel to the plane of the chassis cover 102, that is, when the chassis cover 102 and the chassis body 103 are locked. In addition, a slide pin 132 is fixed to the top end of the second slider 130.
Further, the first slider 140 is installed in the base 110, and the first slider 140 can slide left and right in a rectangular space formed by the wall surface of the base 110, the support frame 112 and the edge of the opening 1021 of the chassis cover 102. The first slider 140 has a hollow S-shaped chute 141, and the slide pin 132 can slide in the S-shaped chute 141. In particular, the S-shaped chute extends into a line perpendicular to the second groove 114 at both ends of the "S" shape, and the slide pin 132 is at a dead point position where it is no longer slidable at both ends of the S-shaped chute 141.
Further, the slide cover 143 is fixed to the first slider 140, and preferably, may be fixed to the first slider 140 by welding, bonding, clamping, or the like. After the sliding lock catch structure 101 is assembled, the sliding nail 132 is matched with the S-shaped sliding groove 141, and can slide along the sliding groove in the S-shaped sliding groove 141. The operator can slide the slide cover 143 within the opening 1021 of the housing cover 102. Preferably, the sliding cover 143 further has lines for increasing friction force on the surface of the sliding cover, so that the sliding cover is easier to slide.

As shown in the figure, referring to fig. 5, the first slider 140 has a hollow S-shaped chute 141, and the slide pin 132 can slide in the S-shaped chute 141. The back of the first slider 140 has a protrusion for penetrating into the compression spring 120 to fix the hook 142 of the compression spring 120. When the compression spring 120 is in a natural state, an extension force is applied to the hook 142, so that the first slider 140 is pushed to the side of the locker part 101 away from the compression spring 120.
Fig. 7 and 8 are schematic views showing a sliding state of the latch slider of the chassis, respectively. As shown in fig. 7, the compression spring 120 pushes the first slider 140 at the end of the locking member 101 away from the compression spring 120 in a natural state, the slide pin 132 is located at the end of the slide groove 141 in the first slider 140, at this time, the lock head 131 of the second slider 130 protrudes out of the locking member 101, the chassis cover 102 is immovable in a direction perpendicular to the face of the chassis cover 102 and a direction horizontal to the chassis cover 102, and the chassis cover 102 is locked with the chassis body 103. As shown in fig. 8, when the box cover 102 needs to be opened, the operator presses and pushes the sliding cover 143, and pushes the first slider 140 connected to the sliding cover 143 to the end of the locking member 101 close to the compression spring 120 through friction force, at this time, the compression spring 120 is in a deep compression state, the slide nail 132 moves to the other end of the first slider 140 along the slide groove 141, and drives the second slider 130 to retract into the second groove 114, so that the box cover 102 is opened.
Optionally, in some cases, because of the influence of electronic components or other structures, the space in the vertical direction is less, and the sliding latch structure is flat and occupies less space.
