Detailed Description
The utility model discloses below combine the figure to explain specifically the utility model, as shown in the figure, the left and right direction in the description figure is lateral shifting's direction, a door latch hook drive structure with self-locking function, including lock box 1, set up latch hook 2 and gleitbretter 3 in the end box 7 part of lock box, and form a whole through gland 4 lock, gleitbretter 3 and the curb plate 12 butt of lock box, set up special-shaped slide 4 on the latch hook and be connected with the cooperation of self-locking pin 5 on the gleitbretter, and the latch hook sets up round hole 6 and is connected with fixed pin 61 on the end box, special-shaped slide on the latch hook divide into arc segment 41 and straightway 42, under the state that the latch hook withdrawed, self-locking pin 5 sets up in the middle part position department of special-shaped slide, when gleitbretter 3 lateral shifting, latch hook 2 atress rotates to screw out and arrives assigned position department after, self-locking pin 5 moves to the tip department of straightway on the straightway; in order to realize the self-locking of the sliding piece 3 and the locking hook 2, the straight line segment 42 is arranged in a horizontal line and is parallel to the bottom box side plate 12; and the straight line segment 21 of the latch hook is perpendicular to the straight line segment 71 of the bottom box thin wall after being screwed out; in order to limit the axial movement of the locking hook along the rotating shaft in the screwing-out process, a convex block 8 is arranged at the butt joint of the locking plate and the gland, and the convex block 8 is also abutted against the lower bottom surface of the gland.
The bottom box is provided with a ribbed plate 72 which is abutted against the sliding sheet.
The sliding plate is provided with an auxiliary lock pin 10, the sliding plate is provided with the auxiliary lock pin, the auxiliary lock pin is arranged in a groove 41 in the gland 4, and the groove 41 can provide guidance for the sliding plate by matching with the auxiliary lock pin.
The left end and the right end of the sliding sheet are respectively abutted against the left wall 73 and the right wall 74 of the inner side of the bottom box in two states of screwing the locking hook in and out.
