The term "more than two" includes two or more than two situations. Example

[0019] like Figures 1 to 16 As shown, an embodiment of the present application provides an explosion-proof LED display screen with a splicing protection structure, including a protective seat 10 and a display screen 20 that can be telescopically arranged on the protective seat 10. The protective seat 10 provides a storage and protection space for the display screen 20. During normal use, the display screen 20 can be located on the outside of the protective seat 10 and completely exposed to display screen 20, so as to display information to the surrounding personnel. When the surrounding environment or the equipment itself does not meet the explosion-proof requirements, it automatically shrinks into the protective seat 10. Specifically, the device also includes: a monitoring heat dissipation component 13 and a display screen protection sheet 30. The monitoring heat dissipation component 13 is arranged on the outer wall of the protective seat 10; the display screen protection sheet 30 is attached to and covers the arc surface of all light-emitting diode lamp beads on the display screen 20, and the display screen protection sheet 30 is used to cool and protect the light-emitting diodes in the display screen 20.

[0020] The display screen 20 is also provided with a convex seat 24, which can be slidably arranged in the inner cavity of the protective seat 10, and the convex seat 24 is provided with: a water pump 245 and a through flow channel 246, wherein the through flow channel 246 is located in the convex seat 24, one end of the through flow channel 246 is connected to the monitoring heat dissipation component 13, and the other end is connected to the display screen protective sheet 30; the water pump 245 is connected to the through flow channel 246 to realize the circulation of water; specifically, the monitoring 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 protective sheet 30 fits and covers the arc surface of the diode lamp bead of the display screen 20, which plays 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, which can It slides in the inner cavity of the protective seat 10, and the through flow channel 246 inside it connects the monitoring heat dissipation component 13 and the display screen protection sheet 30. The water pump 245 is connected to the through flow channel 246 to realize water circulation, and the heat is transferred from the display screen protection sheet 30 to the monitoring heat dissipation component 13 for release. When working, the staff pulls out the display screen 20 through the handle 23, and the clamping seat 40 fixes the display screen 20 to put it in a display state. The display screen protection sheet 30 provides protection and liquid cooling effect. The monitoring 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 in the protrusion 24 shrinks the display screen 20. The overall structure achieves good heat dissipation, protection and the ability to cope with dust environments, effectively protecting the display screen 20 and extending its service life.

[0021] like Figure 1 , Figure 2 , Figure 3 , Fig. 9 and Fig.10 As shown, in some examples, further, 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; an inner rope channel 141 is provided in the connecting rope 14, one end of the connecting rope 14 is connected to the monitoring and heat dissipation component 13, and the other end extends to the inner cavity of the protrusion 24 and is connected to the through flow channel 246.

[0022] In this example, it can be understood that the storage shell 11 serves as the main body of the protective seat 10 and is used to provide a basic containing structure; the slide rail 12 is fixed to the inner wall of the storage shell 11 to provide guidance and support for the sliding of the protrusion 24, ensuring that the display screen 20 can be smoothly extended and retracted; the connecting rope 14, on the one hand, serves as a connecting component between the storage shell 11 and the display screen 20, and on the other hand, is used to transmit liquid cooling medium through the inner rope channel 141 in the connecting rope 14, one end of the inner rope channel 141 is connected to the monitoring 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 heat dissipation component 13 for heat dissipation, and then flow back to the display screen 20 side through the inner rope channel 141, thereby providing a continuous heat absorption function.

[0023] like Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 , Fig.11 and Fig.12 As shown, in some examples, further, the display screen 20 includes: at least two abutment seats 21, corner wraps 22 and a handle 23, at least two abutment seats 21 are arranged on the outer wall of the display screen 20 away from one end of the protrusion 24; the corner wraps 22 can be detachably installed on the two exposed bottom corners of the display screen 20; the handle 23 is placed on the outer wall of the display screen 20 between the two corner wraps 22.

[0024] In this example, the abutment seat 21 is arranged on the outer wall of the end of the display screen 20 away from the convex seat 24. When the display screen 20 extends out of the protective seat 10, the abutment seat 21 can contact the structure on which the protective seat 10 is placed, such as contacting with the wall or contacting with the outer wall of other equipment, to support and stabilize the display screen 20. Even if the display screen 20 is fully extended, the abutment structure of the abutment seat 21 can ensure the structural stability of the display screen 20 and can resist a certain impact force; the wrap angle 22 can be detachably installed at the exposed bottom corner of the display screen 20, which can protect the bottom corner of the display screen 20 from collision and damage. The structural firmness of the display screen 20 is improved; the handle 23 is arranged on the outer wall of the display screen 20 between the two wrapping corners 22, so that the staff can pull the display screen 20 to extend it from the protective seat 10; during 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 abutment seat 21 moves with the display screen 20 and moves on the wall or the outer wall of the device where it is placed, providing support for the back of the display screen 20. Therefore, this example improves the safety of the operation of the display screen 20, and also provides effective protection for the corners of the display screen 20, thereby extending the service life of the display screen 20.

[0025] like Fig.13 , Fig.14 and Fig.15 As shown, in some examples, further, the display screen protection sheet 30 includes: a plurality of spherical grooves 31, a plurality of guide plates 32 and two splicing protrusions 33, the plurality of spherical grooves 31 are arranged on the outer wall of the display screen protection sheet 30 that is attached to one side of the light-emitting diode; and correspond one to one with the position of the diode in the display screen 20; a plurality of guide plates 32 are arranged in the inner cavity of the display screen protection sheet 30, and form a flow channel that can flow through the position of the spherical grooves 31; the two splicing protrusions 33 are both arranged on the outer wall of the display screen protection sheet 30, and are connected to the two ends of the flow channel.

[0026] In this example, the spherical groove 31 is arranged on the outer wall of the display screen protection sheet 30 on the side where the diode is attached and corresponds 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 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. Fig.14 and Fig.15 As shown, the guide plate 32 can be in a straight line shape or in a continuously bent shape; it can be specifically selected according to the arrangement of the light-emitting diodes in the display screen; two splicing protrusions 33 are arranged on the outer wall of the display screen protective plate 30, and are connected to the inlet and outlet positions at both ends of the flow channel, and the two splicing protrusions 33 are used for splicing with other components, and finally connected to the detection heat dissipation component through the inner rope channel 141 to ensure that the circulation path of the cooling medium is complete; when working, the cooling medium flows in the channel formed by the guide plate 32, takes away the heat through the spherical groove 31, and is connected with other components through the splicing protrusions 33 to realize heat transfer and circulation; thereby 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.

[0027] like Figure 3 , Figure 8 , Fig. 9 and Fig.10 As shown, in some examples, further, the boss 24 is also provided with: a rotating shaft 241, a damping device 242, a winding section 243, a coiling spring seat 244 and two splicing sockets 247. The rotating shaft 241 is rotatable around its own axis and is arranged in the inner cavity of the boss 24; the damping device 242 is fixed in the middle of the inner cavity of the boss 24 and is sleeved on the rotating shaft 241 to prevent the rotating shaft 241 from rotating too quickly; the winding section 243 is arranged on the rotating shaft 241 to wind up the connecting rope 14; the coiling spring seat 244 is connected to both ends of the rotating shaft 241; and is fixed in the inner cavity of the boss 24; two splicing sockets 247 are arranged in the display screen 20 or the boss 24, and the splicing sockets 247 can be plugged into the splicing bosses 33 one by one.

[0028] In this example, it should be noted that the rotating shaft 241 can rotate around its own axis in the inner cavity of the protruding seat 24, mainly to provide 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 protruding seat 24 and is sleeved on the rotating shaft 241, which can control the rotation speed of the rotating shaft 241 to avoid the disadvantage of rapid retraction of the display screen 20 caused by its excessive 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 an area for winding the connecting rope 14, ensuring that the connecting rope 14 can be wound and released in an orderly manner during the extension and retraction of the display screen 20; the winding spring seat 244 connects the two ends of the rotating shaft 241 and is fixed in the inner cavity of the protruding seat 24, providing the rotating shaft 241 with rotation power. When the display screen 20 is in the inner cavity of the protective seat 10, the winding spring in the inner cavity of the winding spring seat 244 does not deform. When the display screen 20 is pulled out, the winding section 243 is wound. The release process of the connecting rope 14 causes the rotating shaft 241 to rotate, and the rotating shaft 241 after rotation drives the winding spring to produce an elastic reset tendency; the two splicing sockets 247 are used to be plugged into the corresponding splicing protrusions 33 of the display screen protection plate 30 to ensure the connectivity of the cooling medium circulation path, and as a detachable configuration, improve the flexibility of the device; when the surrounding environment is abnormal, the monitoring of the surrounding environment by the heat dissipation component 13 can generate a control signal, and the control signal can be transmitted to the clamping seat 40, and the clamping seat 40 releases the limit restriction on the protrusion 24, and the rotating shaft 241 rotates under the action of the torque of the winding 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 be retracted into the protective seat 10 at a reasonable speed, thereby improving the reliability and overall performance of the display screen 20 during use.

[0029] like Figure 3 and Fig.16 As shown, in some examples, further, the monitoring heat dissipation component 13 includes: a protrusion 131, an air flow channel 132, a driving device 133, a central axis 134, a plurality of heat dissipation fins 135, a guide fan blade 136 and a dust sensor 137, the protrusion 131 is protrudingly arranged on the outer wall of the protective seat 10; the air flow channel 132 is arranged in the inner cavity of the protrusion 131; the driving device 133 is arranged on the inner wall of the inner cavity of the protrusion 131; the central axis 134 is fixedly arranged in the inner cavity of the air flow channel 132 In the figure, the central axis 134 is in a hollow state, and the two ends of the central axis 134 are respectively connected to the 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 axis 134; the guide blades 136 are rotatably mounted on the outer wall of the central axis 134; the guide blades 136 are transmission-connected to the driving device 133; the dust sensor 137 is fixedly mounted on the outer wall of the central axis 134, and the dust sensor 137 is signal-connected to the clamping seat 40.

[0030] In this example, it can be understood that the protrusion 131 is protrudingly arranged on the outer wall of the protective seat 10 and fixed to the side of the display screen 20; the air flow channel 132 is arranged in the inner cavity of the protrusion 131, which can be opened in the inner part of the protrusion 131 in the form of a through channel. The air flow channel 132 is the path for air flow, so that external air can flow through the inner part 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 is continuously in a low temperature state. On the other hand, by introducing air from the external environment into the protrusion 131, the air condition in the surrounding environment, especially the dust condition, can be monitored in real time, achieving the effect of killing two birds with one stone. In addition, the channel is not exposed to the outside to avoid interference from external work and does not require frequent maintenance. The driving device 133 is placed on the inner wall of the inner cavity of the protrusion 131 to provide power for the guide fan blades 136, so that the guide fan can rotate continuously to maintain the continuous flow of air in the air flow channel 132; the central axis 134 is fixed in the inner cavity of the air flow channel 132 and is empty. In the central state, the central axis 134 does not rotate as a whole and is arranged in a fixed manner. The central axis 134 is hollow and connected to the inner rope channels 141 on both sides for transmitting cooling medium and providing support for the heat dissipation fins 135 and the guide blades 136; the heat dissipation fins 135 are fixed in the air flow channel 132 and connected to the outer wall of the central axis 134 to increase the heat dissipation area; the guide blades 136 are sleeved on the outer wall of the central axis 134 and are connected to the driving device 133 for transmission, and promote air flow when rotating to enhance the heat dissipation effect; the dust sensor 137 is fixed on the outer wall of the central axis 134 and is connected to the card seat 40 for monitoring the dust content; when working, the driving device 133 drives the guide blades 136 to rotate, and the air flows in the air flow channel 132 and dissipates heat through the heat dissipation fins 135. At the same time, the dust sensor 137 monitors the dust and sends a signal to the card seat 40 when the dust exceeds the standard; therefore, efficient heat dissipation and dust monitoring functions can be achieved, the display screen 20 can be effectively protected, and its working stability and service life can be improved.

[0031] like Figure 2 , Figure 3 , Figure 4 , Figure 7 , Figure 8 and Fig. 9 As 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 close to 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 protrusion 24 and corresponds to the position of the electromagnet 42, and the limit block 43 is used to maintain the extended state of the display screen 20.

[0032] 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 close to the extended side of the display screen 20 to provide 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 limit block 43 is fixed on the outer wall of the protrusion 24 and corresponds to the position of the electromagnet 42, and is used to be clamped at the electromagnet 42 to keep the display screen 20 in the extended state.

[0033] Specifically, the electromagnet 42 is extended out of the card seat 40 in the default state and is maintained in the external 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 is extended out of the protective seat 10, the electromagnet 42 cooperates with the limit block 43 to lock the display screen 20 in the extended position; when the dust sensor 137 detects that the dust exceeds the standard, etc., the electromagnetic driver 41 changes the magnetic force of the electromagnet 42 and absorbs the electromagnet 42 into the card seat 40, so that it is separated from the limit block 43, and the display screen 20 can be retracted; therefore, this example ensures that the display screen 20 can be stably extended for display during normal use, and can be retracted in time when protection is needed.

[0034] In some examples, further, a temperature sensor is disposed in the boss 24 , the temperature sensor is located on the through-flow channel 246 , and the temperature sensor signal is connected to the electromagnetic driver 41 .

[0035] In this example, it should be noted that the temperature sensor is located on the through-flow channel 246 in the protrusion 24, and can monitor the temperature conditions in the through-flow channel 246 in real time; the temperature sensor is connected to the electromagnetic driver 41 signal, and 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 related components according to the received signal, such as changing the magnetic force of the electromagnet 42, thereby switching the position of the display screen 20; so as to realize 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, so as to avoid reacting to dust in the surrounding environment, thereby further enhancing the explosion-proof effect of the device.

[0036] like Fig.11 As shown, in some examples, further, the abutment seat 21 is also provided with: a sealing sheet 211 and at least two rollers 212, the sealing sheet 211 is fixedly set at the end of the abutment seat 21, and the sealing sheet 211 protrudes from the edge of the display screen 20 in a bent shape; at least two rollers 212 are placed on the abutment seat 21.

[0037] 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 role in sealing and explosion-proofing; 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, wherein the supporting structure can be a wall, or it can be other equipment or a supporting 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.

[0038] like Fig.12 As shown, in some examples, further, the corner 22 also includes an end limit piece 221, and the end limit piece 221 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 is slightly shaken 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.
