[0043] Please refer to Figure 1 As shown in the drawings, the present application provides an electronic screen, which comprises a frame 2 and a screen body 3 arranged on the frame 2, and a corner guard mechanism 1 is arranged at both ends of the side edge of one side of the frame 2. The corner guard mechanism 1 can be extended out of the frame 2 or accommodated on the frame 2. When the electronic screen is vertically stored or placed against the wall, the corner guard mechanism 1 extends out of the frame 2 and abuts against the to-be-placed position, avoiding the edge of the screen body 3 from being knocked when contacting the to-be-placed position, so as to avoid damage to the bulb at the edge position of the screen body 3.

[0044] In other embodiments, more than two corner protection mechanisms 1 may be provided on the side of the electronic screen, and the multiple corner protection mechanisms 1 may be arranged at intervals to ensure the stability of the electronic screen support.

[0045] For details, please refer to Figures 2 to 4 As shown, in some embodiments of the present application, the corner protection mechanism 1 includes a base 10 and a support leg 20. The base 10 is disposed on the side of the frame 2, and the support leg 20 is rotatably disposed on the base 10. By rotating, the support leg 20 can switch between a first state and a second state. When the support leg 20 is in the second state, it is retracted on the base 10, which can avoid interfering with the installation of the electronic screen. When the support leg 20 rotates from the second position to the first position, the free end of the support leg 20 extends outside the frame 2, so that when the electronic screen is erected, the free end of the support leg 20 can abut against the placement position.

[0046] In some embodiments of this application, please refer to Figures 2 to 4 As shown, the support leg 20 is provided with a first locking structure 21. When the support leg 20 is in the first state and the second state, the base body 10 is provided with a second locking structure 11 that cooperates with the first locking structure 21. The first locking structure 21 and the second locking structure 11 can be locked and unlocked with each other to limit the position of the support leg 20 when the support leg 20 is in the first state and the second state, and to facilitate the rotation of the support leg 20. For ease of operation, the first locking structure 21 can be a ball, and the second locking structure 11 can be a ball groove. The ball is inserted into the ball groove to achieve the locking of the first locking structure 21 and the second locking structure 11. When a force greater than the compression of the ball is applied to the support leg 20, the first locking structure 21 and the second locking structure 11 can be unlocked.

[0047] If the support legs 20 are in the second state, they will protrude from the base 10, which will affect the overall aesthetics. Therefore, in some embodiments of the present application, please refer to Figures 2 to 4 As shown, a receiving groove 12 is provided on the base body 10, a rotating shaft 13 is provided in the receiving groove 12, and a rotating shaft hole 22 is provided at one end of the supporting foot 20. When the supporting foot 20 rotates to the second state in which it abuts against the groove wall of the receiving groove 12, the supporting foot 20 is accommodated in the receiving groove 12, and the side of the supporting foot 20 facing away from the receiving groove 12 is flush with the outer side surface of the base body 10.

[0048] When the support foot 20 is in the first state, the first locking member and the second locking member are unlocked to prevent the worker from misoperating or the electronic screen from being subjected to external force. Figures 2 to 4As shown, a slide groove 14 parallel to the screen body 3 is provided on the base body 10 at the rotation axis 13. The longitudinal section of the rotation axis hole 22 is an oblong hole, so that the rotation axis 13 can move within the length of the oblong hole, and the direction of movement is perpendicular to the rotation axis 13. When the support leg 20 rotates from the second state to be parallel to the screen body 3, the support leg 20 can slide along the slide groove 14 until the end of the support leg 20 located at the rotation axis 13 is accommodated in the slide groove 14. The slide groove 14 can limit the position of the support leg 20 at the end of the rotation axis 13. When the electronic screen is in an upright position, the weight of the electronic screen is all pressed on the support leg 20, so that the support leg 20 will not move along the slide groove 14 in the direction away from the frame 2, thereby limiting the rotation of the support leg 20. In this state, the first locking member and the second locking member will not disengage.

[0049] If the support foot 20 is limited by the wall of the chute 14, the wall of the chute 14 may be damaged by excessive pressure. Figures 2 to 4 As shown, a second limiting groove 24 is provided on one of the sidewalls of the chute 14 on the side facing away from the accommodating groove 18 and the end of the support leg 20 located on the rotating shaft 13, and a second limiting block 16 is provided on the other side. The second limiting block 16 matches the second limiting groove 24. The second limiting groove 24 can be provided on the groove wall of the chute 14 and the second limiting block 16 can be provided on the support leg 20, or the second limiting block 16 can be provided on the groove wall of the chute 14 and the second limiting groove can be provided on the support leg 20. The cooperation between the second limiting groove 24 and the second limiting block 16 enables the groove wall of the second limiting groove 24 to limit the position of the second limiting block 16, thereby increasing the blocking force when the support leg 20 rotates, thereby further preventing the support leg 20 from rotating in the first position.

[0050] Since the cooperation between the first limiting block 15 and the first limiting groove 23 and the slide groove 14 can only limit the support leg 20 to be located at the end of the rotating shaft 13, and there is no restriction on the free end of the support leg 20. Therefore, in some embodiments of the present application, please refer to Figures 2 to 4As shown, limiting grooves 17 are provided on the side walls on both sides of the slide 14, limiting sliders 25 are provided on both sides of the support foot 20, and receiving grooves 18 are provided on the side walls on both sides of the receiving groove 12. When the support foot 20 is in the first state, the limiting slider 25 can be slidably set in the limiting groove 17. When the support foot 20 is in the second state, the limiting slider 25 is received in the receiving groove 18. It should be noted that when the support foot 20 rotates from the second state to be parallel to the screen body 3, the limiting slider 25 is aligned with the limiting groove 17. As the support foot 20 moves along the slide 14, the limiting slider 25 enters the limiting groove 17 and moves along the limiting groove 17. The slide 14 wall of the limiting groove 17 can limit the position of the limiting slider 25, thereby preventing the support foot 20 from rotating when it is in the first state and increasing the resistance to rotation of the support foot 20 when it is in the first state.

[0051] When the support leg 20 is in the second state, in order to prevent the support leg 20 from falling out of the receiving groove 12, in some embodiments of the present application, please refer to Figures 2 to 4 As shown, a magnetic sheet 27 is provided on the side of the support leg 20 facing the base 10 . When the support leg 20 is in the second state, the support leg 20 and the base 10 will not separate due to the magnetic attraction of the magnetic sheet 27 .

[0052] Further, in some embodiments of this application, please refer to Figures 2 to 4 As shown, the magnetic sheet 27 is located at the free end of the support leg 20, so that the magnetic attraction force exerts a greater rotational torque on the support leg 20 to rotate along the rotating shaft 13 toward the receiving groove 12, thereby increasing the ability to resist the support leg 20 from separating from the receiving groove 12. In addition, although the support leg 20 is mainly limited by the cooperation of the first locking structure 21 and the second locking structure when it is in the second state, the provision of the magnetic sheet 27 can further limit the position of the support leg 20 within the receiving groove 12, so that the support leg 20 will not be displaced relative to the receiving groove 12, ensuring that the support leg 20 will not separate from the receiving groove 12.

[0053] In some embodiments of this application, please refer to Figures 2 to 4 As shown, a first limiting block 15 is provided on one of the groove wall of the receiving groove 12 and the side of the supporting leg 20 facing the receiving groove 12, and a first limiting groove 23 is provided on the other. When the supporting leg 20 is in the second state, the first limiting block 15 is received in the first limiting groove 23 to limit the position of the supporting leg 20. Alternatively, the first limiting block 15 may be provided on the groove wall of the receiving groove 12 and the supporting leg 20 may have the first limiting groove 23, or the first limiting groove 23 may be provided on the groove wall of the receiving groove 12 and the supporting leg 20 may have the first limiting block 15. With the first limiting block 15 and the first limiting groove 23 in alignment, the supporting leg 20 will not move within the receiving groove 12.

[0054] In order to facilitate the operation of rotating the support foot 20 from the second state to the first state, in some embodiments of the present application, please refer to Figures 2 to 4 As shown, a hand-grip groove 26 is provided on the free end of the support foot 20. The operator can apply force to the hand-grip groove 26 to drive the support foot 20 to rotate, thereby disengaging the first locking structure 21 from the second locking structure 11 and driving the support foot 20 to rotate.

[0055] In some embodiments of this application, please refer to Figures 2 to 4 Figures 2 to 4 Figures 2 to 4 As shown, a wear-resistant sheet 28 is provided at the free end of the supporting foot 20. The wear-resistant sheet 28 extends beyond the end surface of the free end of the supporting foot 20. The wear-resistant sheet 28 is stronger than the supporting foot 20, thereby protecting the supporting foot 20 from damage and improving the service life of the supporting foot 20.

[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
