[0021] See Figure 1 As shown, this embodiment of the utility model provides a self-locking translation mechanism, including an inclined plate 1, with the distal end of the inclined plate 1 being the high end and the proximal end being the low end. It also includes a sliding plate 2 and a self-locking drive device 3. Specifically, a linear slide rail 11 is provided on the inclined plate 1, and the sliding plate 2 is slidably mounted on the linear slide rail 11 via a slider. Limiting blocks 12 are respectively provided at the high and low ends of the inclined plate 1 to limit the sliding stroke of the sliding plate 2 on the linear slide rail 11. A base 13 is provided at the bottom of the inclined plate 1.
[0022] See Figure 2 As shown, the slide plate 2 is slidably mounted on the inclined plate 1; specifically, anti-collision blocks 23 adapted to the limiting blocks 12 are respectively provided at both ends of the slide plate 2. A boss 21 is provided on the slide plate 2, and a connecting lug 22 for connecting the fourth rotating shaft 310 is provided at the proximal end of the boss 21. The distal end of the boss 21 is bent upward to form a vertical plate portion 24. A reinforcing plate 25 is provided between the vertical plate portion 24 and the boss 21.
[0023] See Figure 3As shown, the self-locking drive device 3 is used to drive the slide plate 2 to slide between the high end and the low end of the inclined plate 1. It includes a fixed seat 301, a flip plate 304, a connecting clamp 305, and a connecting plate 306. The fixed seat 301 is installed on the low end of the inclined plate 1. The flip plate 304 has an L-shaped structure, and one end of the flip plate 304 is hinged to the far end of the fixed seat 301 through the first rotating shaft 307. The other end of the flip plate 304 is hinged to the piston rod of the drive cylinder 302 through the second rotating shaft 308. Specifically, the cylinder body of the drive cylinder 302 (cylinder) is hinged to the near end of the fixed seat 301 through the fifth rotating shaft 311, and the piston rod of the drive cylinder 302 is connected to the second rotating shaft 308 through the U-shaped joint 303. The proximal end of the connecting clamp 305 is fixedly connected to the bend of the flip plate 304; the proximal end of the connecting plate 306 is hinged to the distal end of the connecting clamp 305 via a third pivot 309, and the distal end of the connecting plate 306 is hinged to the proximal end of the slide plate 2 via a fourth pivot 310; when the piston rod of the drive cylinder 302 extends and drives the slide plate 2 to the high-end locking position of the inclined plate 1, the first pivot 307, the third pivot 309, and the fourth pivot 310 are in the same straight line. Specifically, when the slide plate 2 slides to the high-end locking position of the inclined plate 1, the first pivot 307, the third pivot 309, and the fourth pivot 310 are in the same straight line, and this straight line is parallel to the inclined plate 1.
[0024] The working principle of this utility model is as follows: When the drive cylinder extends, it drives the first, second, third, fourth, and fifth rotating shafts to perform hinge movements. However, the slide can only move in a straight line along the linear guide. When the slide hits the limit block, it stops moving. The first, third, and fourth rotating shafts are on the same straight line, and the entire mechanism is at a dead point. At this time, the slide will not slide down due to gravity. To retract, the piston of the drive cylinder must move in a straight line to open it.
