The sliding section 321 slides to the end facing the hanging hole 130 and is located above the hanging wheel 200, and the sliding section 321 abuts against the upper end of the hanging hole 130 to limit the upward sliding of the hanging wheel 200.

At least one side of the sliding section 321 in the up-down direction exceeds the anti-falling section 322, and an abutting section 323 is formed; in the anti-drop position, the side of the abutment portion facing the hanging hole 130 abuts against the side wall of the sliding groove 313 facing the change gear 200. At least one side of the sliding section 321 in the up-down direction exceeds the anti-drop section 322, and correspondingly, in the sliding groove 313, the aperture of at least one end of the sliding groove 313 in the up-down direction exceeds the perforation 314.

It should be noted that, the hanging plate 100 is provided with a corresponding limiting hole 140, the anti-falling section 322 is located in the limiting hole 140 and can slide in the limiting hole 140, and the side wall of the limiting hole 140 can limit the sliding position of the anti-falling section 322.

In this embodiment, the anti-falling assembly 300 further includes an elastic member 330, where the elastic member 330 is clamped between the anti-falling pin 320 and the anti-falling body 310, so as to drive the anti-falling pin 320 to move toward the hanging hole 130, and keep the anti-falling pin 320 at the anti-falling position.

In this embodiment, the elastic member 330 is a compression spring, one end of the compression spring abuts against the anti-disengagement pin 320, and the other end abuts against the anti-disengagement housing 310. In some embodiments, the elastic member 330 is a tension spring, and two ends of the tension spring are fixedly connected to the anti-falling pin 320 and the anti-falling body 310, respectively. In other embodiments, the elastic member 330 may be an elastic structure such as a spring plate.

In this embodiment, a through hole 324 penetrating from front to back is formed in the sliding section 321; a protruding stopper 315 is formed in the sliding groove 313; the stop portion 315 extends into the through hole 324; the elastic member 330 is disposed in the through hole 324 of the anti-release pin 320, one end of the elastic member 330 facing the hanging hole 130 abuts against a sidewall of the through hole 324, and one end of the elastic member 330 facing away from the hanging hole 130 abuts against the stop portion 315.

In the present embodiment, a protruding limit rib 325 is formed on a side wall of the through hole 324 facing the hanging hole 130; the limit rib 325 extends in a direction away from the anti-drop section 322; the elastic member 330 is sleeved on the periphery of the limit rib 325, so as to effectively avoid the elastic member 330 from radial deformation or distortion along the elastic member 330. In some embodiments, the through hole 324 is not provided with the limiting rib 325, and the through hole 324 is concavely provided with a limiting groove, and one end of the elastic member 330 extends into and abuts against the limiting groove.

One end of the anti-drop pin 320 facing the hanging hole 130 is formed with an inclined guide slope 326; the guide slope 326 extends in the direction from top to bottom toward the hanging hole 130; in the process that the gear 200 extends into the penetrating segment 131 and moves downwards, the gear 200 is abutted against the guide inclined surface 326, and the anti-drop pin 320 is driven to move back to the hanging hole 130, so that the anti-drop pin 320 is in an unlocking position, and when the gear 200 moves downwards to a preset position, the anti-drop pin 320 returns to the anti-drop position under the action of elastic force and abuts against the upper end of the gear 200, so that the movement of the gear 200 is limited.

The anti-slip assembly 300 further includes a pull cord 340; one end of the pull cord 340 is fixed on the anti-drop pin 320, and the other end of the pull cord is threaded out of the anti-drop housing 310, so as to pull the anti-drop pin 320 to move back to the hanging hole 130. When the display device needs to be detached from the hanging plate 100, the pull rope 340 is pulled to drive the anti-falling pin 320 to move back to the hanging hole 130, so that the anti-falling pin 320 and the hanging wheel 200 are misplaced, and the hanging wheel 200 can move upwards, so that the hanging hole 130 is pulled out from the penetrating section 131.

In the present utility model, the hanging plate 100 is used for fixing on a wall, and the hanging hole 130 penetrating from front to back is formed on the hanging portion 120 of the hanging plate 100. The hanging hole 130 is fixed on the back of the display main body 20, the hanging wheel 200 can pass through the penetrating section 131 of the hanging hole 130 from front to back and can slide downwards in the hanging hole 130, so that the bottom end of the hanging wheel 200 is supported on the limiting section 132 of the hanging hole 130, the rear end of the hanging wheel 200 is attached to the rear side surface of the hanging plate 100 forwards, and the forward movement of the hanging wheel 200 is limited, so that the display main body 20 is hung on the hanging plate 100, and the display main body 20 is hung on a wall.

The rear side of the hanging plate 100 protrudes forward to form the hanging portion 120, and a space is provided between the hanging portion 120 and the wall in the front-rear direction. The anti-drop assembly 300 is fixed on the back of the engaging portion 120 and is located in the interval between the engaging portion 120 and the wall, when in the anti-drop position, one end of the anti-drop assembly 300 facing the hanging hole can abut against the upper end of the change gear 200 in the limiting section 132 to limit the upward movement of the change gear 200, limit the change gear 200 in the limiting section 132, and prevent the change gear 200 from falling out from the hanging hole. On the basis of ensuring the ultrathin wall hanging 10, the display main body 20 is effectively prevented from falling off the hanging plate 100, and the display device is effectively protected.
