[0045] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0046] Embodiment 1

[0047] See also Figure 1-5, a full-color LED display screen with high safety, comprising a main body component 1, the main body component 1 comprising: a side plate 11, a connecting block 12 is movably connected to the front side of the side plate 11; a display screen body 13, fixedly connected to the right side of the connecting block 12; a mounting component 2 is arranged on the side plate 11 and the connecting block 12, and the mounting component 2 comprises: a mounting frame 21, arranged on the right side wall of the side plate 11; a spring 22, symmetrically arranged on the inner side wall of the mounting frame 21; a limit block 23, arranged at the opposite end of the spring 22, and the right side wall of the limit block 23 has an inclined surface; a limit hole 231, symmetrically opened on the outer side wall of the connecting block 12; a connecting plate 24, respectively fixedly connected to the top of the limit block 23; a frame 25, fixedly connected to the top of the mounting frame 21, and the top of the connecting plate 24 extends to the inside of the frame 25; a linkage mechanism 26, arranged on the frame 25 and the connecting plate 24. The linkage mechanism 26 includes: a spring 261 fixedly connected to the bottom surface of the frame 25; a pressure rod 262 fixedly connected to the top of the spring 261, the pressure rod 262 penetrates and extends to the top of the frame 25; a connecting rod 263 symmetrically and hinged to the bottom of the pressure rod 262; a push plate 264 hinged to the opposite end of the connecting rod 263; a slider 265 symmetrically arranged at the bottom of the push plate 264, a slide groove for the slider 265 to slide is provided on the bottom surface of the frame 25, and the opposite end of the slider 265 is fixedly connected to the connecting plate 24. A protective shell 267 is movably connected to the top of the frame 25, and the protective shell 267 is sleeved on the outside of the pressure rod 262.

[0048] When in use, the staff uses the installation component 2 to conveniently install the display screen body 13: the staff pushes the connecting block 12 toward the installation frame 21, and when the connecting block 12 contacts the inclined surface on the front side of the limit block 23, the limit block 23 is squeezed outward at the same time, and the limit block 23 squeezes the spring 1 22. When the limit hole 231 on the connecting block 12 moves to the direction of the limit block 23, the elastic force of the compressed spring 1 22 bounces the limit block 23 into the limit hole 231, completing the limiting of the connecting block 12 and the display screen body 13 by the limit block 23. The display screen body 13 can be installed by only pushing the connecting block 12, thereby improving the installation efficiency. When the display screen body 13 is damaged and needs to be disassembled for repair, the linkage mechanism 26 is used to realize the simultaneous movement of the two limit blocks 23 outward, so as to facilitate the release of the restriction on the connecting block 12: the staff presses the pressure rod 262, the pressure rod 262 compresses the spring 261, and drives the hinged connecting rods 263 on both sides to move to both sides, the connecting rod 263 drives the push plate 264 and the slider 265 to slide to both sides, the slider 265 guides the movement of the push plate 264, and when the push plate 264 moves, it pushes the connecting plate 24 connected to it to both sides, and the connecting plate 24 drives the limit blocks 23 on both sides to disengage from the limit holes 231 at the same time, thereby releasing the restriction on the connecting block 12 and improving the disassembly efficiency. The protective shell 267 protects the pressure rod 262 and can be opened when the pressure rod 262 is in use. The pressure rod 262 is protected when there is no need to disassemble the display screen body 13 to prevent the pressure rod 262 from being accidentally touched, causing the display screen body 13 to fall off, damaging the display screen body 13 or injuring the user. The provision of the protective shell 267 improves the safety of the device when in use.

[0049] Embodiment 2

[0050] On the basis of the first embodiment, an auxiliary function is added.

[0051] See also Figure 1-5 The side plate 11 and the installation frame 21 are provided with a fixing mechanism 27, and the fixing mechanism 27 includes: a bracket 271, symmetrically arranged on the right side wall of the installation frame 21; a bidirectional screw rod 272, rotatably connected between the brackets 271; a motor 273, arranged on the right side wall of the bracket 271 on the right side, and the output shaft of the motor 273 is fixedly connected with the bidirectional screw rod 272; a threaded block 274, symmetrically and threadedly connected to the bidirectional screw rod 272; a vertical plate 275, respectively arranged on the top of the threaded block 274, and a through slot for the vertical plate 275 to move is opened at the bottom of the installation frame 21. A telescopic rod 266 is fixedly connected between the pressure rod 262 and the inner bottom surface of the frame 25, and the second spring 261 is sleeved on the outside of the telescopic rod 266. The first spring 22 is divided into multiple groups.

[0052] The fixing mechanism 27 fixes the position of the limit block 23 after the limit block 23 limits the connection block 12, so as to avoid the problem of the limit block 23 moving and causing damage to the installation stability of the display screen body 13: after the limit block 23 enters the limit hole 231, the motor 273 is started, and the motor 273 drives the bidirectional screw rod 272 to rotate. The threaded block 274 threadedly connected to the bidirectional screw rod 272 approaches or deviates from each other as the bidirectional screw rod 272 rotates. The rotation direction of the motor 273 is controlled so that the threaded block 274 approaches each other until the two vertical plates 275 on the threaded block 274 abut against the different surfaces of the limit block 23, and the motor 273 is turned off. At this time, the vertical plate 275 limits the movement of the limit block 23, thereby improving the stability of the display screen body 13 after installation. At the same time, when it is necessary to disassemble the display screen body 13, the motor 273 is reversed so that the two vertical plates 275 are away from the limit block 23. At this time, the linkage mechanism 26 can be used to normally release the restriction on the limit block 23. The telescopic rod 266 is extended and retracted along with the extension and retraction of the second spring 261, and the telescopic rod 266 guides the extension and retraction of the second spring 261, so as to prevent the second spring 261 from being skewed when being extended and retracted after being squeezed by the pressure rod 262, thereby affecting the normal use of the linkage mechanism 26. The multiple groups of equally divided springs 1 22 increase the contact area between the springs 1 and the limit block 23, improve the supporting effect on the limit block 23, and increase the stability of the limit block 23 when it moves.
