[0023] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0024] See also Figure 1-5 The embodiment of the utility model provides a technical solution: an LED display screen structure that is easy to replace, including a shell 1, a cover plate 3 is rotatably arranged on the shell 1 through a first rotating shaft 5, a visual window is arranged on the cover plate 3, and a mounting groove 2 is opened in the shell 1, a display screen body 4 is installed in the mounting groove 2, a stopper 9 and a sliding rod 8 are vertically slidably arranged in the shell 1, the stopper 9 is used to initially limit the display screen installed in the mounting groove 2, and a connecting rod 11 is rotatably arranged in the shell 1 through a second rotating shaft 10, the sliding rod 8 is used to unlock the fixed block 6 and drive the stopper 9 to move at the same time, one end of the connecting rod 11 is movably connected to the sliding rod 8, and the other end is movably connected to the stopper 9, so that when the sliding rod 8 moves vertically, the connecting rod 11 drives the stopper 9 to slide; a fixed block 6 is slidably arranged in the cover plate 3, and the fixed block 6 slides vertically along the cover plate 3 (refer to Figure 4 ), and the cover plate 3 is connected to the fixed block 6 by an elastic member 7, one end of the elastic member 7 is fixedly connected to the cover plate 3, and the other end is fixedly connected to the fixed block 6. A fixing groove 14 adapted to the fixed block 6 is provided on the shell 1. The cooperation between the fixed block 6 and the fixing groove 14 can fix the cover plate 3 after the cover plate 3 is closed. The position of the sliding rod 8 corresponds to the fixed block 6, that is, in this setting, the sliding rod 8 can not only squeeze the fixed block 6 to slide and unlock the cover plate 3, but also drive the stopper 9 to move upward through the sliding of the sliding rod 8 to release the limit on the display screen, thereby facilitating the replacement of the LED display screen.

[0025] The utility model can fix the cover plate 3 during the process of rotating and closing the cover plate 3 by cooperating with the fixed block 6 and the fixed groove 14, and can unlock the cover plate 3 by cooperating with the sliding rod 8, that is, the design can realize the fast fixing and opening of the cover plate 3, thereby realizing the fast installation of the display screen, and facilitating the maintenance and replacement of the display screen. At the same time, the cooperating stopper 9 and the connecting rod 11 can perform preliminary limit fixing on the display screen through the stopper 9 when the display screen is installed, so as to facilitate the subsequent closing of the cover plate 3 and avoid the display screen from tipping over when the cover plate 3 is closed, so as to facilitate the installation of the display screen. At the same time, the sliding rod 8 can not only squeeze the fixed block 6 to slide and unlock the cover plate 3, but also can drive the stopper 9 to move upward by the sliding of the sliding rod 8, so as to release the limit on the display screen, thereby facilitating the replacement of the LED display screen, and solving the problems of screw fixing, inconvenient operation, time-consuming and labor-intensive, and inconvenience caused by subsequent maintenance and replacement of the LED display screen.

[0026] In another embodiment provided by the utility model, sliders 12 are provided at both ends of the connecting rod 11, and U-shaped grooves 13 suitable for the sliders 12 are opened on the sliding rod 8 and the stop block 9, and the slider 12 is movably arranged in the U-shaped groove 13. This design enables the slider 12 to slide along the U-shaped groove 13 when the connecting rod 11 rotates, so that the sliding rod 8 and the stop block 9 slide vertically.

[0027] In another embodiment of the present invention, a torque spring is sleeved on the second rotating shaft 10, and the elastic force of the torque spring is used to drive the connecting rod 11 to rotate and reset, that is, when the pressing plate 15 loses pressure, the connecting rod 11 rotates and resets, thereby driving the sliding rod 8 and the stopper 9 to reset.

[0028] In another embodiment of the present invention, a torque spring is provided on the first rotating shaft 5, and the elastic force of the torque spring is used to drive the cover 3 to rotate and open. This design enables the cover 3 to open automatically when the cover 3 is unlocked, that is, when the fixing block 6 is disengaged from the fixing groove 14.

[0029] In another embodiment of the present invention, a rounded corner is provided on the fixing block 6 so that the fixing block 6 can be squeezed to slide and shrink into the cover plate 3, that is, this design makes the fixing block 6 not affect the rotation of the cover plate 3, and can fix the cover plate 3 after it is closed.

[0030] In another embodiment of the present invention, the elastic member 7 is a compression spring, and its elastic force is used to drive the fixing block 6 to slide and reset, that is, after the cover plate 3 is rotated and closed, the fixing block 6 can automatically reset to fix the cover plate 3.

[0031] In another embodiment provided by the utility model, there are two sliding rods 8, and the two sliding rods 8 are connected by a pressing plate 15. This design enables the two sliding rods 8 to slide by pressing the pressing plate 15, and the movement of the two stoppers 9 can be realized at the same time, which makes the operation more convenient.

[0032] In another embodiment of the present invention, a pressing block 16 is provided on the inner side of the cover plate 3. The pressing block 16 is a component made of elastic material and can press against the display screen body 4 after the cover plate 3 is closed to limit and fix the display screen body 4.

[0033] In actual use, when the display screen needs to be replaced, pressure is first applied to the pressing plate 15 so that the pressing plate 15 drives the sliding rod 8 to slide vertically downward (refer to Figure 4 ), so that the sliding rod 8 squeezes the abutting block 16, so that the abutting block 16 slides and shrinks into the cover plate 3 and enters the cover plate 3. At this time, the torque spring on the first rotating shaft 5 drives the cover plate 3 to rotate and open. At the same time, during the vertical sliding process of the sliding rod 8, the connecting rod 11 is driven to rotate, and the connecting rod 11 drives the stopper 9 to slide vertically upward, that is, the stopper 9 slides vertically and shrinks into the housing 1 (refer to Figure 5 ), the limit is released, at this time, the display screen body 4 can be taken out, and then the replaced display screen body 4 is installed in the installation groove 2, the pressing plate 15 is released, and the torque spring on the second rotating shaft 10 drives the connecting rod 11 to rotate and reset, so that the sliding rod 8 slides upward and resets, and the stopper 9 slides downward to block and limit the display screen body 4, and then the cover plate 3 is rotated and closed to fix it. After the cover plate 3 is opened, the elastic restoring force of the elastic member 7 drives the fixing block 6 to slide and reset. During the process of the cover plate 3 being rotated and closed, the fillet on the fixing block 6 is squeezed by the shell 1 to slide and shrink into the cover plate 3. When the cover plate 3 is closed, at this time, the fixing block 6 is opposite to the fixing groove 14, and the elastic restoring force of the elastic member 7 drives the fixing block 6 to slide and reset and insert into the fixing groove 14, so as to fix the cover plate 3.

[0034] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
