Specifically, the front face 22 of the display module 2 faces outward, and several display modules 2 are spliced ​​together to form a display screen. The box body 1 and the display module 2 are adsorbed and connected to each other through the first magnetic attraction component 3 and the second magnetic attraction component 5. The first magnetic attraction component 3 and the second magnetic attraction component 5 both include magnets for easy installation and removal. In addition, in the embodiment of the present invention, the first end of the safety rope 6 is set as a lasso 61 and the lasso 61 is formed by a fishing line. The diameter of the fishing line is usually small but the strength is very strong and the cost is low. The material of the fishing line is usually nylon line, carbon line, braided line of polyethylene fiber, high-horsepower line of ultra-high molecular weight polyethylene fiber, and the diameter of the fishing line can be selected to be greater than or equal to 0.5 mm and less than or equal to 1.5 mm, preferably 0.8 mm. The height of the middle waist of the I-shaped connecting part 30 is greater than the straightness of the fishing line. The difference between the height of the middle waist of the I-shaped connecting part 30 and the diameter of the fishing line can be set to be greater than or equal to 0.1 mm and less than or equal to 0.3 mm. The diameter of the fishing line is very small and can be directly sleeved on the middle waist of the I-shaped connecting part 30. The first end of the safety rope 6 can be connected to the display module 2 by tightening the adjusting sleeve 62. That is, the first magnetic component 2 is used for connection with the second magnetic component 5, and also has a hook function to be connected with the lasso 61. There is no need to find additional space to glue and fix the hook. At the same time, a connecting member 66 is set at the second end of the safety rope 6, and the connecting member 66 is connected to the box body 1, so as to prevent the display module 2 from accidentally falling off during maintenance and use. In addition, the number of safety ropes 6 connected to each display module 2 can be designed and connected according to actual needs.

[0026] The embodiment of the present invention uses a fishing line to form a lasso 61 and sleeves it on the I-shaped connecting portion 30 formed between the first magnetic attraction component 3 and the back side 21, thereby achieving the connection between the display module 2 and the safety rope 6, effectively solving the problem that the IC components on the back side 21 of the existing display module 2 are densely packed and there are no hooks for fixing positions or the fixing of the hooks will affect the IC components. It saves space, saves process and meets the installation requirements of the safety rope 6. The design is very clever.

[0027] In the embodiment of the present invention, Figures 5 to 7As shown, the first magnetic member 3 is an inverted convex structure and includes a first magnetic head 31 and a first intermediate rod 32 provided on the first magnetic head 31. The first intermediate rod 32 is connected to the back 21 of the display module 2 to form an I-shaped connection portion 30, and the lasso 61 is sleeved on the first intermediate rod 32. Specifically, the first magnetic head 31, the first intermediate rod 32 and the back 21 form an I-shaped connection portion 30 for clamping the lasso 61. After the lasso 61 is sleeved on the first intermediate rod 32, the adjustment sleeve 62 moves and locks the lasso 61 to fix the lasso 61 on the first intermediate rod 32.

[0028] In some other specific implementations of the present invention, the first magnetic member 3 is in an I-shaped shape and includes a second magnetic head, a first magnetic tail, and a second intermediate rod portion disposed between the second magnetic head and the first magnetic tail portion, the second magnetic head, the first magnetic tail, and the second intermediate rod portion form an I-shaped connecting portion 30, the first magnetic tail portion is connected to the back surface 21 of the display module 2, and the lasso 61 is sleeved on the second intermediate rod portion. Specifically, after the lasso 61 is sleeved on the second intermediate rod portion, the adjustment sleeve 62 moves and locks the lasso 61 to fix the lasso 61 on the second intermediate rod portion.

[0029] In some specific implementations of the embodiments of the present invention, a connecting rod member is installed on the back 21 of the display module 2, and the connecting rod member includes a connecting rod, and the connecting rod has a docking end face. The size of the first magnetic member 3 is larger than the size of the docking end face, and the first magnetic member 3 is connected to the docking end face and forms an inverted convex structure with the connecting rod. An I-shaped connecting portion 30 is formed between the back 21, the connecting rod and the first magnetic member 3, and the lasso 61 is sleeved on the connecting rod. Specifically, the connecting rod member can be a boss structure, including a connecting head and a connecting rod provided on the connecting head, the connecting head is connected to the back 21, and a second magnetic member 5 is installed on the connecting rod. The size of the first magnetic member 3 can be larger than the size of the connecting head, or can be equal to the size of the connecting head, or can be smaller than the size of the connecting head. Of course, the connecting rod member can also only include a connecting rod, one end of the connecting rod is connected to the back 21 of the display module, and the other end of the connecting rod is connected to the first magnetic member 3.

[0030] In the embodiment of the present invention, Figure 2 As shown, the fishing line is brought together at both ends to form a lasso 61. At this time, both ends of the fishing line extend out from the adjusting sleeve 62. Specifically, the adjusting sleeve 6 may be provided with two through holes corresponding to the both ends of the fishing line, and the both ends are slidably connected to the corresponding through holes. In some other specific embodiments, only one through hole may be provided on the adjusting sleeve 6, and both ends extend out from this one through hole.

[0031] In some other specific implementations of the present invention, Figure 3As shown, one end of the fishing line is fixed to the adjusting sleeve 62 and the other end of the fishing line passes through the adjusting sleeve 62 to form a noose 61.

[0032] In some specific implementations of the present invention, Figure 4 As shown, two ends of the fishing line are respectively passed through the adjusting sleeve 62 from two ends of the adjusting sleeve 62 and passed out from the adjusting sleeve 62 to form a lasso 61.

[0033] It should be noted that the specific structure of the lasso 61 is not limited, as long as it can cooperate with the adjustment sleeve 62 to be locked on the I-shaped connecting portion 30.

[0034] In the embodiment of the present invention, Figure 2 As shown, the adjustment sleeve 62 includes at least one rubber ring sleeved on the lasso 61. Specifically, the rubber ring is provided with a hole for the fishing line to pass through, and the adjustment sleeve 62 with a rubber ring structure has a simple structure and is light in weight.

[0035] In the embodiment of the present invention, Figure 2 As shown, at least one rubber ring includes a first rubber ring 621 close to the ring 611 of the lasso 61, and the outer diameter of the first rubber ring 621 is smaller than the height of the middle waist of the I-shaped connecting part 30 so that the first rubber ring 621 is embedded in the I-shaped connecting part 30. Specifically, as Figures 5 to 7 As shown, the height of the middle waist portion corresponds to the length of the first middle rod portion 32 or the length of the second middle rod portion or the length of the connecting rod. The outer diameter of the first rubber ring 621 is set to be smaller than the height of the middle waist portion of the I-shaped connecting portion 30. After locking the lasso 61, the first rubber ring 621 can be inserted into the I-shaped connecting portion 30 to effectively prevent the lasso 61 from falling off from the I-shaped connecting portion 30. In addition, a second rubber ring 622 can be set on the side of the first rubber ring 621 away from the ring 611. The second rubber ring 622 is used to press against the first rubber ring 621 to prevent the first rubber ring 621 from loosening. At the same time, in order to further enhance the anti-retraction effect, a third rubber ring or even a fourth rubber ring can be set in sequence.

[0036] In the embodiment of the present invention, a plurality of metal gaskets 4 are evenly arranged on the back side 21 of the display module 2, and at least one rubber ring includes a first rubber ring 621 close to the ring 611 of the lasso 61, and the first rubber ring 621 avoids the corresponding metal gasket 4. Specifically, the display module 2 is rectangular, and a plurality of metal gaskets 4 are evenly arranged on the edge of the back side 21 of the display module 2, and a plurality of first magnetic members 3 are evenly arranged on the inner side of the area surrounded by the plurality of metal gaskets 4, so the metal gaskets 4 need to be avoided when the lasso 61 and the adjustment sleeve 62 are installed.

[0037] In the embodiment of the present invention, the first rubber ring 621 has a central axis, the central axis is oriented to the side of the corresponding first magnetic member 3, and the angle between the central axis and the horizontal direction is greater than or equal to 0 degrees and less than or equal to 60 degrees. Specifically, the side here refers to the direction other than directly above and directly below the first magnetic member 3, and the horizontal direction refers to the direction parallel to the length direction of the lower bottom surface of the display module 2. The display module 2 is vertically arranged, that is, the lower bottom surface of the display module 2 is oriented to the ground. When the central axis of the first rubber ring 621 is also oriented to the ground, if the display module 2 falls off the box 1, the display module 2 falls toward the ground under the action of gravity, and the lasso 61 is easily pulled off. Therefore, the central axis is oriented to the horizontal direction or the central axis is oriented to the side of the corresponding first magnetic member 3, and the angle between the central axis and the horizontal direction is greater than or equal to 0 degrees and less than or equal to 60 degrees, which can effectively prevent the lasso 61 from being pulled off. Of course, the display module 2 can also be arranged horizontally or tilted. In this case, the first rubber ring 621 also needs to avoid the metal gasket 4 and avoid the situation where the central axis of the first rubber ring 621 is facing the bottom surface of the display module 2 and is perpendicular to the bottom surface.

[0038] In the embodiment of the present invention, the safety rope 6 further includes a rope portion 64, one end of the rope portion 64 is connected to the lasso 61 via a first fixing member 63, and the other end of the rope portion 64 is connected to a connecting member 66. Specifically, the other end of the rope portion 64 is connected to the connecting member 66 via a second fixing member 65. The material of the rope portion 64 can be different from that of the lasso 61 and the cross-sectional diameter of the rope portion 64 can be larger. The specific material of the rope portion 64 can be selected according to actual needs, as long as it meets the strength requirements of the safety rope 6.

[0039] In the embodiment of the present invention, Figure 2 as well as Figures 8 to 9 As shown, the connecting member 66 is a metal ring, a mounting post 11 is provided on the box body 1, the second magnetic member 5 is threadedly connected to the mounting post 11, the metal ring is sleeved on the mounting post 11 and the outer diameter of the second magnetic member 5 is larger than the inner diameter of the metal ring. Specifically, the second magnetic component 5 includes a mounting seat 51, a mounting hole is provided on one side of the mounting seat 51, and a threaded column extending outward is provided on the other side of the mounting seat 51, a magnet 52 is embedded in the mounting hole, and a threaded hole is provided at the end of the mounting column 11, and the threaded column is threadedly connected to the threaded hole. When installing the metal ring, the metal ring is first sleeved on the mounting column 11, and then the threaded column is threadedly connected to the threaded hole to install the second magnetic component 5, thereby limiting the metal ring on the mounting column 11. In some other embodiments, a lobster clasp that cooperates with the metal ring can also be provided on the box body 1, and the connection with the metal ring is achieved through the lobster clasp. In addition, the space on the box body 1 is relatively ample, and other structures such as hanging buckles or hooks can be provided on the box body 1 for matching and fixing. The specific selection can be made according to actual needs and is not limited here.

[0040] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention still fall within the scope covered by the present invention.
