[0039] As Figures 1 to 16 As shown, an explosion-proof LED display screen with a splicing protection structure is provided in an embodiment of the present application, which includes a protection seat 10 and a display screen 20 that can be telescopically arranged in the protection seat 10. The protection seat 10 provides an accommodation and protection space for the display screen 20. During normal use, the display screen 20 can be located outside the protection seat 10 and the entire display screen 20 is completely exposed, so as to display information to the surrounding personnel. When the surrounding environment or the conditions of the device itself do not meet the explosion-proof requirements, it automatically retracts into the protection seat 10. Specifically, this device further includes: a monitoring and heat dissipation component 13 and a display screen protection sheet 30. The monitoring and heat dissipation component 13 is arranged on the outer wall of the protection seat 10; the display screen protection sheet 30 is attached to and covers the arc surface of all the light-emitting diode lamp beads on the display screen 20. The display screen protection sheet 30 is used to cool and protect the light-emitting diodes in the display screen 20.

[0040] Among them, a convex seat 24 is further provided on the display screen 20. The convex seat 24 is slidably arranged in the inner cavity of the protective seat 10. Inside the convex seat 24, there are provided: a water pump 245 and a through-flow channel 246. Among them, the through-flow channel 246 is located inside the convex seat 24. One end of the through-flow channel 246 communicates with the monitoring and heat dissipation component 13, and the other end communicates with the display screen protection piece 30. The water pump 245 is communicated with the through-flow channel 246 to realize the circulating flow of water. Specifically, the monitoring and heat dissipation component 13 is arranged on the outer wall of the protective seat 10, which can monitor environmental dust and assist in heat dissipation. The display screen protection piece 30 fits and covers the arc surface of the diode lamp beads of the display screen 20, playing a role in cooling and protection. The convex seat 24 can be used as a part of the display screen 20 and is located on one side of the inner cavity of the protective seat 10. It can slide in the inner cavity of the protective seat 10. The through-flow channel 246 inside it communicates the monitoring and heat dissipation component 13 and the display screen protection piece 30. The water pump 245 is connected to the through-flow channel 246 to realize the water circulation, transferring the heat from the display screen protection piece 30 to the monitoring and heat dissipation component 13 for release. During operation, the staff pulls out the display screen 20 through the handle 23, and the clamping seat 40 fixes the display screen 20 to make it in the display state. The display screen protection piece 30 provides protection and liquid cooling effects. The monitoring and heat dissipation component 13 releases heat and monitors dust when the liquid cooling medium flows in. When the dust exceeds the standard, the clamping seat 40 releases the restriction, and the power structure inside the convex seat 24 makes the display screen 20 contract. The overall structure realizes good heat dissipation, protection and the ability to cope with the dust environment, effectively protecting the display screen 20 and prolonging its service life.

[0041] As Figure 1 , Figure 2 , Figure 3 , Figure 9 and Figure 10 shown, in some examples, furthermore, the protective seat 10 includes a fixed storage shell 11, and also includes: at least one set of slide rails 12 and a connecting rope 14. At least one set of slide rails 12 is fixed in the inner wall of the storage shell 11. A rope inner channel 141 is arranged inside the connecting rope 14. One end of the connecting rope 14 communicates with the monitoring and heat dissipation component 13, and the other end extends into the inner cavity of the convex seat 24 and communicates with the through-flow channel 246.

[0042] In this example, it can be understood that the storage shell 11 serves as the main part of the protective seat 10 to provide a basic accommodating structure. The slide rails 12 are fixed on the inner wall of the storage shell 11 to provide guidance and support for the sliding of the convex seat 24, ensuring that the display screen 20 can be extended and retracted smoothly. On the one hand, the connecting rope 14 serves as a connecting component between the storage shell 11 and the display screen 20. On the other hand, the rope inner channel 141 inside the connecting rope 14 is used to transport the liquid cooling medium. One end of the rope inner channel 141 is connected to the monitoring and heat dissipation component 13, and the other end is connected to the through-flow channel 246, so that the heat can be transferred to the monitoring and heat dissipation component 13 for heat dissipation, and then flow back to the display screen 20 side through the rope inner channel 141, thereby being able to provide a continuous heat absorption function.

[0043] As Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 and Figure 12 As shown, in some examples, further, the display screen 20 includes: at least two abutting seats 21, corner protectors 22 and a handle 23. The at least two abutting seats 21 are arranged on the outer wall of the end of the display screen 20 far from the convex seat 24; the corner protectors 22 can be detachably installed on the two exposed bottom corners of the display screen 20; the handle 23 is arranged on the outer wall of the display screen 20 between the two corner protectors 22.

[0044] In this example, the abutting seats 21 are arranged on the outer wall of the end of the display screen 20 far from the convex seat 24. When the display screen 20 extends out of the protective seat 10, the abutting seats 21 can contact the structure arranged on the protective seat 10, such as contacting the wall surface or the outer wall of other devices, playing a role in supporting and stabilizing the display screen 20. Even when the display screen 20 extends out completely, through the abutting structure of the abutting seats 21, the structural stability of the display screen 20 can be ensured, and it can withstand a certain impact force; the corner protectors 22 are detachably installed at the exposed bottom corners of the display screen 20, which can protect the bottom corners of the display screen 20 from collision and damage, and improve the firmness of the structure of the display screen 20; the handle 23 is arranged on the outer wall of the display screen 20 between the two corner protectors 22, which is convenient for the staff to pull the display screen 20 to make it extend out of the protective seat 10. During the operation, the staff applies force through the handle 23 to drive the display screen 20 to move out of the protective seat 10, and the abutting seats 21 move with the display screen 20 and move on the wall surface or the outer wall of the installed device, providing support for the back of the display screen 20. Therefore, this example improves the safety of operating the display screen 20, also provides effective protection for the corners of the display screen 20, and extends the service life of the display screen 20.

[0045] As Figure 13 , Figure 1,4 and Figure 15 As shown, in some examples, further, the display screen protector 30 includes: a plurality of spherical grooves 31, a plurality of flow guiding plates 32 and two splicing protrusions 33. The plurality of spherical grooves 31 are arranged on the outer wall of the display screen protector 30 that fits the side of the light emitting diode; and correspond one by one to the positions of the diodes in the display screen 20; the plurality of flow guiding plates 32 are arranged in the inner cavity of the display screen protector 30 and form a flow channel that can flow through the positions of the spherical grooves 31; the two splicing protrusions 33 are both arranged on the outer wall of the display screen protector 30 and are connected to both ends of the flow channel.

[0046] In this example, the spherical groove 31 is provided on the outer wall of the display protection sheet 30 on the side where the diode is attached, corresponding to the position of the diode, which can increase the contact area between the protection sheet and the diode and improve the heat dissipation effect; the flow guide plate 32 is arranged in the inner cavity of the protection sheet to form a flow channel, which can guide the flow of the cooling medium, so that the cooling medium flows through the spherical groove 31 and takes away the heat generated by the diode, as Figure 14 and Figure 15 shown. The flow guide plate 32 can be in a straight shape or a continuously bent shape; specifically, it can be selected according to the arrangement of the light-emitting diodes in the display screen; the two splicing convex ports 33 are arranged on the outer wall of the display protection sheet 30 and are connected to the inlet and outlet positions at both ends of the flow channel. The two splicing convex ports 33 are used for splicing with other components and are finally connected to the detection and heat dissipation component through the inner channel 141 of the rope to ensure the integrity of the circulation path of the cooling medium; during operation, the cooling medium flows in the channel formed by the flow guide plate 32, takes away heat through the spherical groove 31, and is connected to other components through the splicing convex port 33 to realize the transfer and circulation of heat; thus effectively improving the heat dissipation efficiency of the display screen 20, playing a good protective role for the light-emitting diodes, and extending the service life of the display screen 20.

[0047] As Figure 3 、 Figure 8 、 Figure 9 and Figure 10 shown, in some examples, further, the convex base 24 is further provided with: a rotating shaft 241, a damping device 242, a winding section 243, a spring seat 244 and two splicing sockets 247. The rotating shaft 241 is rotatably arranged around its own axis in the inner cavity of the convex base 24; the damping device 242 is fixed in the middle of the inner cavity of the convex base 24 and is sleeved on the rotating shaft 241 to prevent the rotating shaft 241 from rotating too fast; the winding section 243 is arranged on the rotating shaft 241 for winding the connecting rope 14; the spring seat 244 is connected to both ends of the rotating shaft 241 and is fixed in the inner cavity of the convex base 24; the two splicing sockets 247 are arranged in the display screen 20 or the convex base 24, and the splicing sockets 247 can be inserted into the splicing convex ports 33 one by one.

[0048] In this example, it should be noted that the rotating shaft 241 can rotate around its own axis within the convex seat 24, mainly providing a rotation basis for the winding of the connecting rope 14; the damping device 242 is fixed in the middle of the inner cavity of the convex seat 24 and sleeved on the rotating shaft 241, which can control the rotation speed of the rotating shaft 241, avoid the drawback of the rapid retraction of the display screen 20 caused by its too fast rotation, and play a protective role in the contraction of the display screen 20; the winding section 243 is arranged on the rotating shaft 241 as the area for winding the connecting rope 14, ensuring that the connecting rope 14 can be wound and released orderly during the telescopic process of the display screen 20; the spring seat 244 is connected to both ends of the rotating shaft 241 and fixed in the inner cavity of the convex seat 24, providing power for the rotation of the rotating shaft 241. When the display screen 20 is in the inner cavity of the protective seat 10, the spring in the spring seat 244 does not deform. When the display is pulled out, through the release process of the connecting rope 14 in the winding state, the rotating shaft 241 rotates, and the rotated rotating shaft 241 drives the spring to generate an elastic reset trend; the two splicing sockets 247 are used to be correspondingly inserted into the splicing protrusions 33 of the display screen protection piece 30, ensuring the connection of the cooling medium circulation path, and as a detachable configuration, improving the flexibility of the device; when the surrounding environment is abnormal, by monitoring the surrounding environment by the monitoring and heat dissipation component 13, a control signal can be generated, and the control signal can be transmitted into the clamping seat 40, and the clamping seat 40 then releases the limit restriction on the convex seat 24. The rotating shaft 241 rotates under the action of the torsion of the spring seat 244, and the winding section 243 winds or unwinds the connecting rope 14, and the damping device 242 controls the rotation speed, so that the display screen 20 can contract into the protective seat 10 at a reasonable speed, improving the reliability and overall performance of the display screen 20 during use.

[0049] As Figure 3 and Figure 16 shown, in some examples, furthermore, the monitoring and heat dissipation component 13 includes: a convex block 131, an air flow channel 132, a driving device 133, a central shaft 134, a plurality of heat dissipation fins 135, a guiding fan blade 136 and a dust sensor 137. The convex block 131 protrudes from the outer wall of the protective seat 10; the air flow channel 132 is arranged in the inner cavity of the convex block 131; the driving device 133 is arranged on the inner wall of the inner cavity of the convex block 131; the central shaft 134 is fixedly arranged in the inner cavity of the air flow channel 132, the central shaft 134 is in a hollow state, and both ends of the central shaft 134 are respectively connected to two rope inner channels 141 on both sides; a plurality of heat dissipation fins 135 are fixed in the air flow channel 132 and connected to the outer wall of the central shaft 134; the guiding fan blade 136 is rotatably sleeved on the outer wall of the central shaft 134; the guiding fan blade 136 is in transmission connection with the driving device 133; the dust sensor 137 is fixedly arranged on the outer wall of the central shaft 134, and the dust sensor 137 is in signal connection with the clamping seat 40.

[0050] In this example, it can be understood that the bump 131 protrudes from the outer wall of the protective seat 10 and is fixed to the side of the display screen 20; the air flow channel 132 is arranged in the inner cavity of the bump 131, and it can be opened in the bump 131 in the form of a through channel. The air flow channel 132 is a path for air flow, enabling external air to flow through the inside of the air flow channel 132. On the one hand, it can improve the heat dissipation effect of the fins and ensure that the cooling medium remains at a low temperature continuously. On the other hand, by introducing the air in the external environment into the bump 131, it can monitor the air condition in the surrounding environment in real time, especially the dust condition, achieving a two-in-one effect. And the channel is not exposed, avoiding external working interference and not requiring frequent maintenance; the driving device 133 is arranged on the inner wall of the inner cavity of the bump 131, providing power for the guide fan blade 136, enabling the guide fan to rotate continuously to maintain the continuous flow of air in the air flow channel 132; the central shaft 134 is fixed in the inner cavity of the air flow channel 132 and is in a hollow state. The central shaft 134 does not rotate as a whole and is set in a fixed manner. The central shaft 134 is hollow and is respectively connected to the inner channels 141 of the ropes on both sides, used for transmitting the cooling medium and providing support for the heat dissipation fins 135 and the guide fan blade 136; the heat dissipation fins 135 are fixed in the air flow channel 132 and are connected to the outer wall of the central shaft 134 to increase the heat dissipation area; the guide fan blade 136 is sleeved on the outer wall of the central shaft 134 and is in transmission connection with the driving device 133, and when rotating, it promotes air flow and enhances the heat dissipation effect; the dust sensor 137 is fixed on the outer wall of the central shaft 134 and is in signal connection with the clamping seat 40, used for monitoring the dust content; during operation, the driving device 133 drives the guide fan blade 136 to rotate, the air flows in the air flow channel 132, is cooled by the heat dissipation fins 135, and at the same time the dust sensor monitors the dust. When the dust exceeds the standard, it sends a signal to the clamping seat 40; therefore, it can realize the functions of efficient heat dissipation and dust monitoring, effectively protect the display screen 20, and improve its working stability and service life.

[0051] As Figure 2 , Figure 3 , Figure 4 , Figure 7 , Figure 8 and Figure 9 shown, in some examples, further, the clamping seat 40 includes: an electromagnetic driver 41, an electromagnet 42 and a limit block 43. The electromagnetic driver 41 is embedded in the inner wall of the protective seat 10 and protrudes near the side where the display screen 20 extends; the electromagnet 42 is movably arranged on the driving end of the electromagnetic driver 41; the limit block 43 is fixedly arranged on the outer wall of the convex seat 24 and corresponds to the position of the electromagnet 42. The limit block 43 is used to maintain the extended state of the display screen 20.

[0052] In this example, the specific structure of the clamping seat 40 is further disclosed. The function of the clamping seat 40 is to limit the contraction of the display screen 20, so that the display screen 20 can remain in the extended state after being pulled out. Specifically, the clamping seat 40 includes an electromagnetic driver 41, which is embedded in the inner wall of the protective seat 10 near the side where the display screen 20 extends, and provides power for the movement of the electromagnet 42; the electromagnet 42 is movably arranged at the driving end of the electromagnetic driver 41 and can move under the action of electromagnetic force; the limiting block 43 is fixed on the outer wall of the convex seat 24 and corresponds to the position of the electromagnet 42, and is used to be clamped on the electromagnet 42 to keep the display screen 20 in the extended state.

[0053] Specifically, the electromagnet 42 is defaultly extended outside the clamping seat 40 and remains in the extended state under the action of the spring. The outer wall of the electromagnet 42 is an inclined surface so that the display screen 20 will not be affected by the electromagnet 42 during the extension process. When the display screen 20 extends out of the protective seat 10, the electromagnet 42 cooperates with the limiting block 43 to be clamped, and the display screen 20 is fixed at the extended position; when the dust sensor 137 detects that the dust exceeds the standard or other situations, the electromagnetic driver 41 changes the magnetic force of the electromagnet 42 and adsorbs the electromagnet 42 into the clamping seat 40, so that it is disengaged from the limiting block 43, and the display screen 20 can contract; therefore, this example ensures that the display screen 20 can be stably extended for display during normal use and can be contracted in time when protection is needed.

[0054] In some examples, further, a temperature sensor is also arranged in the convex seat 24. The temperature sensor is located on the through-flow channel 246, and the temperature sensor is signal-connected to the electromagnetic driver 41.

[0055] In this example, it should be noted that the temperature sensor is located on the through-flow channel 246 in the convex seat 24, and can monitor the temperature situation in the through-flow channel 246 in real time; the temperature sensor is signal-connected to the electromagnetic driver 41. When the temperature is too high, the temperature sensor transmits the signal to the electromagnetic driver 41; the electromagnetic driver 41 can control the actions of relevant components according to the received signal, such as changing the magnetic force of the electromagnet 42, so as to switch the position of the display screen 20; to realize the real-time monitoring and automatic control of the temperature of the display screen 20, effectively prevent the display screen 20 from being damaged due to overheating, and enable it to automatically retract into the protective seat 10 when the temperature is too high, avoiding reacting to the dust in the surrounding environment, thereby further improving the explosion-proof effect of this device.

[0056] As Figure 11 shown, in some examples, further, the abutting seat 21 is also provided with: a sealing piece 211 and at least two rollers 212. The sealing piece 211 is fixedly arranged at the end of the abutting seat 21, and the sealing piece 211 protrudes from the edge of the display screen 20 in a bent shape; at least two rollers 212 are arranged on the abutting seat 21.

[0057] In this example, the sealing sheet 211 is fixed to the end of the abutment seat 21 and the edge is bent, and the bend includes a bending point, so that the sealing sheet 211 can be in an inclined state and contact the installed structure regardless of whether it follows the display screen 20 to extend or retract. When the display screen 20 is in the retracted state, it can effectively prevent dust and other impurities from entering the gap between the protective seat 10 and the display screen 20, thereby playing a sealing and explosion-proof role; the roller 212 is placed on the abutment seat 21 and can roll and fit on the outer wall of the supporting structure on which the protective seat 10 is installed, where the supporting structure can be a wall, or other equipment or support frame in the factory. When the display screen 20 is extended or retracted, the roller 212 can reduce the friction between the abutment seat 21 and the protective seat 10, so that the display screen 20 moves more smoothly.

[0058] like Figure 12 As shown, in some examples, further, the wrap angle 22 also includes an end limit piece 221, which is located on the outside of the display screen protective sheet 30. The end limit piece 221 is located on the outside of the display screen protective sheet 30. During the use of the display screen 20, it can limit the display screen protective sheet 30 to ensure that the protective sheet is in close contact with the display screen 20; when the display screen 20 is subjected to external force or slight shaking during normal use, the end limit piece 221 can prevent the protective sheet from separating from the display screen 20, ensuring that the protective sheet can continue to effectively cool and protect the display screen 20; and enhance the connection stability between the display screen protective sheet 30 and the display screen 20.

[0059] The above are merely embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application should all be included within the scope of the claims of the present application.
