DETAILED DESCRIPTION

[0031] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0032] like Figures 1 to 9 As shown, an embodiment of the present invention provides a display screen that is easy to maintain, comprising: a display screen body 2 and an inner iron frame 1, a back plate 5 is provided on the back of the display screen body 2, and positioning components 6 are provided at the four corners of the inner iron frame 1, and the back plate 5 is detachably connected to the inner iron frame 1 through the positioning components 6;

[0033] like Figures 1 to 9 As shown, by the design that positioning components 6 are provided at the four corners inside the middle iron frame 1, the four positioning components 6 can pre-position the back panel 5 so that the back panel 5 is first stably attached to the middle iron frame 1, thereby facilitating the subsequent fixation of the back panel 5. Therefore, the use of the positioning components 6 at the four corners can effectively improve the efficiency of the display screen body 2 during installation.

[0034] The installation and removal components 4 are provided in two groups, and the two groups of installation and removal components 4 are respectively provided on both sides of the middle iron frame 1, and the two groups of installation and removal components 4 are composed of quick-release components 401 and two groups of fixed shells 402. The quick-release components 401 are provided on one side of the middle iron frame 1, and the two groups of fixed shells 402 are movably connected to the middle iron frame 1, and the two groups of fixed shells 402 are movably connected to the quick-release components 401, so that the two groups of fixed shells 402 are approached or moved away from each other through the quick-release components 401, and the two groups of fixed shells 402 are detachably connected to the back plate 5, and the two ends on both sides of the middle iron frame 1 are movably connected with the heat dissipation net 3, and the heat dissipation net 3 and the fixed shell 402 are provided in pairs.

[0035] like Figures 1 to 9 As shown, the two sets of fixed shells 402 are designed to be movably connected to the quick-release component 401. The two sets of fixed shells 402 can be synchronously moved closer to each other through the quick-release component 401 to achieve rapid fixation of the back panel 5 to the middle iron frame 1. At the same time, the two sets of fixed shells 402 can also be synchronously moved away from each other to achieve rapid removal of the back panel 5. Therefore, it is convenient to disassemble the display screen body 2 for maintenance.

[0036] Furthermore, the positioning assembly 6 includes a card rod 602 and a hook 603, the hook 603 is fixedly connected to the back plate 5, and the card rod 602 is elastically connected to the middle iron frame 1, the hook 603 is engaged with the outer side of the card rod 602, and an arc-shaped groove is provided on one side of the hook 603, and the arc angle of the arc-shaped groove is consistent with that of the card rod 602, so that the arc-shaped groove fits the outer side of the card rod 602; both ends of the outer side of the card rod 602 are fixedly installed with limit plates 604, and a docking cavity is formed between the two groups of limit plates 604, and the internal space of the docking cavity is consistent with the width of the hook 603; spring push rods 601 are provided at the four corners inside the middle iron frame 1, and one end of the piston rod of the spring push rod 601 is fixedly connected to one group of limit plates 604, so that the card rod 602 is elastically connected to the middle iron frame 1 through the spring push rod 601;

[0037] like Figures 1 to 9As shown, through the design of the hook 603 being engaged with the outside of the card rod 602, when the back panel 5 is installed, the two groups of hooks 603 on the upper side of the back panel 5 can be pushed downward and engaged with the outside of the two groups of card rods 602, and then the back panel 5 is pushed upward, and the two groups of hooks 603 on the lower side of the back panel 5 are engaged with the outside of the other two groups of card rods 602, and then the back panel 5 is automatically centered under the elastic action of the four groups of spring top rods 601, thereby realizing the positioning of the back panel 5, thereby facilitating the steady fixation of the subsequent installation and removal of the components 4. When disassembly is required, it is only necessary to push the back panel 5 up and down, and push the hooks 603 on the back panel 5 to the outside of the card rod 602 to achieve disassembly.

[0038] It should be noted that, among the four groups of spring top rods 601 mentioned above, two groups are divided into a pair, and the two pairs of spring top rods 601 are respectively located at the upper and lower parts of the middle iron frame 1, and the movable rods of the upper and lower groups of spring top rods 601 are relatively movable. Therefore, the back panel 5 can be easily pushed up and down to achieve installation and disassembly, thereby greatly improving the installation and disassembly efficiency of the display screen body 2 and facilitating disassembly and maintenance by the staff.

[0039] Furthermore, docking blocks 7 are fixedly mounted on both ends of the back panel 5 on the side away from the display screen body 2. Both ends of the docking blocks 7 are inclined. The two sets of fixed shells 402 have inclined grooves at opposite ends, and the inclined grooves are corresponding to the ends of the docking blocks 7. The docking block 7 is located between the two sets of fixed shells 402, and the docking block 7 is perpendicular to the inclined grooves.

[0040] like Figures 1 to 9 As shown, by the design in which the docking block 7 and the inclined groove are arranged vertically correspondingly, when the two sets of fixed shells 402 are close to each other, the inclined groove and the two ends of the docking block 7 are used to squeeze and fix, thereby realizing the fixed connection between the middle iron frame 1 and the back plate 5. On the contrary, when the two sets of fixed shells 402 are away from each other, the back plate 5 can be disassembled.

[0041] Furthermore, a sliding plate 9 is fixedly installed at one end of the same side of the two sets of fixed shells 402, and a movable groove is opened at both ends of both sides of the middle iron frame 1. A sliding rod 8 is fixedly installed inside the movable groove. The sliding plate 9 is slidably sleeved on the outside of the sliding rod 8, and a return spring 10 is fixedly installed on one side of the sliding plate 9. One end of the return spring 10 is fixedly connected to the inside of the movable groove, and one end of the sliding plate 9 is fixedly connected to the heat dissipation network 3;

[0042] like Figures 1 to 9As shown, by the design of fixing a return spring 10 on one side of the sliding plate 9, the sliding plate 9 can drive the fixed shell 402 and the heat dissipation net 3 to rise and fall synchronously, and the force of the return spring 10 is used to move the two groups of fixed shells 402 away from each other, so that when the two groups of fixed shells 402 are cancelled from being fixed to each other by the quick-release component 401, the two groups of fixed shells 402 can be automatically moved away from each other by the return spring 10. Therefore, when the user completes the operation of the quick-release component 401, the next step is to push the display screen body 2 up and down and disassemble the display screen body 2, so that the user can conveniently disassemble the display screen body 2 for maintenance.

[0043] Furthermore, a connecting plate 4011 is fixedly mounted on one side of the two sets of heat dissipation nets 3 on the same side, and a plug-in rod 4012 is fixedly mounted on one end of the opposite side of the two sets of connecting plates 4011. The two sets of plug-in rods 4012 are symmetrically arranged, and the other ends of the opposite sides of the two sets of connecting plates 4011 are each provided with a plug-in slot, and one end of the plug-in rod 4012 is engaged with the inside of the plug-in slot;

[0044] like Figures 1 to 9 As shown, by the design that one end of the plug-in rod 4012 is engaged with the inside of the plug-in slot, when the two groups of heat dissipation nets 3 are close to each other, their respective plug-in rods 4012 are plugged into the inside of each other's plug-in slot, thereby achieving the first step of fixing the two groups of heat dissipation nets 3 to each other.

[0045] Furthermore, the quick-release component 401 includes a mounting seat 4013 and four groups of clamping rods 4014, two groups of clamping rods 4014 are arranged in pairs, and the four groups of clamping rods 4014 are all movably connected to the mounting seat 4013, the mounting seat 4013 is fixedly connected to the middle iron frame 1, and the mounting seat 4013 is located between the two groups of movable grooves, both ends of one side of the mounting seat 4013 are provided with fitting grooves, the plug-in rod 4012 is located inside the fitting groove, and the plug-in rod 4012 is located between the two groups of clamping rods 4014; both ends of the interior of the mounting seat 4013 are provided with fixed grooves, and the two groups of fixed grooves are arranged in communication, and the fixed The interior of the groove is communicated with the interior of the fitting groove. One end of the clamping rod 4014 is fixedly installed with a rotating seat 12. The rotating seat 12 is rotatably installed in the fixed groove, and a reset groove is opened on one side of the rotating seat 12. A rotating rod 14 is fixedly installed in the reset groove. A torsion spring 13 is sleeved on the outside of the rotating rod 14. One end of the torsion spring 13 is fixedly connected to the rotating seat 12, and the other end of the torsion spring 13 is fixedly installed in the fixed groove. The clamping rod 4014 is close to the outside of the plug-in rod 4012 through the torsion spring 13. Two groups of card slots 11 are opened on the outside of the plug-in rod 4012, and the two groups of card slots 11 are symmetrically arranged.

[0046] like Figures 1 to 9As shown, through the design that the connecting rod 4012 is located between the two groups of clamping rods 4014, the two groups of clamping rods 4014 can be close to each other under the action of the torsion spring 13, so that they are always attached to the outside of the connecting rod 4012. When the opposite ends of the two groups of heat dissipation nets 3 contact the mounting seat 4013 at the same time and the connecting rod 4012 is engaged with the inside of the connecting slot, the two groups of clamping rods 4014 are automatically engaged with the inside of the slot 11 under the action of the torsion spring 13, thereby achieving the fixation of the two groups of heat dissipation nets 3 and the mounting seat 4013. Therefore, the stability of the two groups of heat dissipation nets 3 and the two groups of fixed shells 402 when they are close to each other is further improved, thereby effectively improving the stability of the display screen body 2 when connected to the middle iron frame 1.

[0047] Furthermore, an adjustment groove is provided at the upper end of each of the two groups of fixed grooves, and two groups of micro gears 4016 are rotatably connected inside the adjustment groove. The two groups of micro gears 4016 are meshed with each other, and the micro gears 4016 are fixedly connected to the rotating seat 12. One side of one group of micro gears 4016 is meshed with a tooth plate 4015, and the tooth plate 4015 is slidably mounted inside the adjustment groove, and a transmission rod 15 is fixedly mounted on one end of the tooth plate 4015. An avoidance hole is provided in the middle of one side of the mounting seat 4013, and the avoidance hole is communicated with the interior of the adjustment groove. The transmission rod 15 is located inside the avoidance hole, and a push plate 4017 is fixedly mounted on one end of the transmission rod 15, and the push plate 4017 is slidably mounted on one side of the mounting seat 4013.

[0048] like Figures 1 to 9 As shown, through the design that one side of one group of micro-gears 4016 is meshedly connected with a tooth plate 4015, when the display screen body 2 needs to be disassembled, the two groups of push plates 4017 are controlled to approach each other, and the two groups of push plates 4017 each drive the tooth plate 4015 to move through the transmission rod 15, so that the two groups of micro-gears 4016 are meshed with each other to achieve the effect of relative rotation. Therefore, the two groups of clamping rods 4014 on the same side can rotate in opposite directions to achieve the effect of moving away from the inside of the card slot 11. Then, the two groups of heat dissipation nets 3 are slid up and down respectively, so that the two groups of fixed shells 402 can move away from each other at the same time, thereby releasing the docking block 7, thereby facilitating the disassembly and maintenance of the display screen body 2.

[0049] It should be noted that by providing a heat dissipation net 3 that can slide up and down, it is not only convenient to control the two sets of fixed shells 402 to move closer or farther away from each other, but also by opening the heat dissipation net 3, it is possible to understand the impurities inside the middle iron frame 1 and the situation of the back plate 5.
